Abstract

The invention concerns a lateral finisher/distributor which can be mounted on the arms of loaders, tractor backhoe loaders, diggers or tractors (1), comprising a container (2) of adjustable height mounted upstream of the carrier device (1) and supported by a support height-adjusting device (13, 14), and a distributor (5) mounted laterally on said container (2). The material tipped into the container (2) by tip trucks is brought by a conveying device, for example screw conveyor (10) or a conveyor belt in front of the distributor (5) and distributed by the withdrawal board of the distributor (5).

Description

Page maker / distributor

The invention relates to a mounting / distributor for mounting on loaders, backhoe loaders, excavators and tractors.

Distributors and pavers are used in road construction in order to distribute road construction material such as sand or asphalt on the road to be built and to install it at a certain height. These devices are called pavers if they not only distribute and install the material, but also compact them. These pavers / distributors are supplied with material by dump trucks by feeding a container attached to the front of the paver / distributor from these dump vehicles. The tipped material is transported to the front and installed there. However, there are also material distribution work that must be carried out in an area where normal pavers / distributors cannot work, must not drive in order not to damage the surface or cannot be loaded by the tippers, e.g. in the manufacture of banquets, in in some cases of foot and bike path or road repair work. The construction machinery industry has developed special equipment for such work, such as banquet manufacturers. The Blaw Knox USA company manufactures banquet manufacturers in which a conveyor belt directed to the side is placed under a front container onto which the material is tipped, onto which the material is tipped from the tipping vehicles. The conveyor belt transports the material to the side next to the Pertiger. The installation width can be adjusted using a dozer blade on the side behind the conveyor belt, the angle of which can be changed on the device. The dozer blade distributes the soil evenly and paves it at a certain height on the paver side. The paver drives on the road without damaging the banquets installed on the side. Another company has a banquet maker manufactured in that it has installed a screw in the container of a normal road paver, with which the soil tilted into the container is conveyed into the area of the banquets to be carried out. Behind the auger on the side of the paver, a divider was set up the width of the banquets to be installed. DEMAG has developed an additional device for its pavers that consists of a conveyor belt that is attached to the bottom of the paver's material container. The material tipped into the paver's container is transported to the side by the conveyor belt. Behind the conveyor belt on the side of the paver there is a distributor device with which the material is distributed and installed at a certain height. This additional device was primarily developed to create footpaths and cycle paths with the paver.

There is a whole range of work in civil engineering and road construction where material has to be installed and distributed on the side. The devices developed so far can do this

Only function to a limited extent. The banquet manufacturers are special devices with which only banquets can be produced. They are self-propelled, expensive devices for a very limited purpose. They are therefore only bought and used by companies that specialize in the manufacture of banquets. For the normal civil engineering and road construction company, the purchase of such a relatively expensive device would not be worthwhile, because although he occasionally does such work, such a device would only be used 5 - 10% a year. In addition, other work in which material has to be installed on the side could not be carried out with such special banquet cutters. The result is that the civil engineering and road construction contractor does this work in a very inefficient and costly manner with equipment that he has anyway, such as Excavator, front loader or backhoe loader, or he must even have this work carried out manually.

The DEMAG additional device for your paver has the following disadvantages: in terms of the design, as the device is designed today, it can only be attached to paver. According to the information provided by telephone, the device is also only available for paver manufacturers and only for DEMAG paver manufacturers. In its current form, this device could not be attached to front loaders, excavators or backhoe loaders. First of all, it would have to be equipped with a container. The device is also much too heavy because it was designed for attachment to pavers. As pavers, asphalt pavers are very heavy and are naturally designed for the installation of road building materials. But even if one took very large and heavy loaders, an attachment to these loaders would not be possible because there are no hydrostatically driven loaders of this size that are required for slow driving when installing material. Loaders up to around 6 - 8 t are mainly equipped with hydrostatic drives. But even if the design of DEMAG were very light, it would not be possible to attach it to a loader because the one-sided load from the laterally protruding conveyor belt always leads to an inclined position of the container and the distributor. All loaders are equipped with low-pressure tires, which yield differently under uneven loads. This is already the case with normal pneumatic tires. The fact that all loaders, excavators, backhoe loaders and tractors are equipped with pneumatic tires not only leads to a one-sided inclination of the container and distributor, which is extremely cumbersome during installation, but this also means that each time the container is refilled give way to the tires due to the refilled material from the tipping vehicle and thus press the container and distributor downwards. This will produce a straight surface impossible through the distributor. The additional device for road pavers, as designed by DEMAG, is therefore not suitable as an attachment for loaders, excavators, backhoe loaders and tractors without additional resources. Apart from the technical impossibility, there is also the impossibility of selling the device to entrepreneurs in acceptable quantities in order to meet the actual needs. According to information, this additional device costs between DM 150,000 and DM 200,000 today. The result is that, although it has been on the market for about 10 years, only a very small number of pieces have been manufactured and sold.

The object of the invention is to produce a light, in its construction simple and inexpensive device with which all lateral distribution work can be carried out and that to all excavators, backhoe loaders and loaders, especially the small loaders of 2-6 t, which as Girls are available for everything on almost any construction site that can be grown.

This object is achieved by a side paver / distributor, which is characterized in that it is attached to the arms of loaders or backhoe loaders, to the boom of excavators or by means of a lifting device on tractors, the side paver / distributor consisting of a container , into which the material is poured and a Ver side device attached to the side of the container and wherein there is also a means of transport that brings the material filled into the container from the container in front of the distribution device and wherein the container or the container distribution device is further equipped with a Support height adjustment device, for example in the form of height-adjustable support wheels or runners, which support the container / distributor device on the ground or road surface. The support height distributions direction as an essential part of the invention, has the following function: the first function is to support the container in order to prevent the container and thus the distributor from lowering when the material is tipped in, thus ensuring the production of a straight surface. This support height adjustment device eliminates the disadvantage of pneumatic tires and enables the installation height to be maintained once it has been set. Without such a facility, the installation of a side paver / distributor would not be possible at all. The second function of the support wheels is to prevent the small 2 - 6 t loader, which as a girl, tends to tip over for everything on the construction site, mainly as a carrier for the side paver / distributor in practice. These small loaders are designed for a lifting load that is less than the weight of the container including the dumped material. This container must be designed larger because it must be adapted to the larger dump trucks that are generally in use. For this reason, the weight load of the container with its material content must be absorbed by the support wheels. It is therefore advantageous if the support wheels are either fitted under the center of gravity of the container or in front of and behind the container. The third function is - for this, the height of the support wheels or runners is adjustable - the height of the screed of the distributor, so that different installation heights of the material are possible. The fourth function is the grading of the screed or the prevention of unwanted inclinations due to the one-sided loading of the distributor and means of transport that protrude to one side. This function is fulfilled on the one hand by the fact that support wheels are provided on both sides of the container and on the other hand that different heights can be set on the support wheels. Because of the support wheels on the distributor side of the container, the weight is reduced balanced by the container with the material on one side and the distributor on the other side. The one-sided height adjustment enables the surface to be installed to be inclined, for example to allow the water to run off from a footpath. The fifth function is achieved in that the support wheels are castors. This makes it possible that material filled into the container can also be moved on the construction site. If, for example, it is not possible to load the container in parking garages or garages or under bridges, the loading can take place outside and the loader can then drive the paver / distributor to the place where the material has to be installed.

In many cases there is between the street where the carrier device can travel with the container and the route where the distributor e.g. to install the asphalt surface for a cycle path, a space in the form of a future green strip. When using a conveyor belt as a means of transport, it can be pushed further to the side or provided with a slide at the bottom or equipped with an adjustable centrifugal plate, whereas the material is thrown off the conveyor belt. The auger is bridged from the container to the adjustable side limiting plate by a fixed or slidable enclosure in the form of a tube or a box open at the top. On the sides of the material to be installed are the limiting plates belonging to the distributor, which keep the material in the desired path.

Advantageously, the distributor can be removed, lowered, folded up and down in relation to the container, and can be folded for transportation in front of the container. The distributor is advantageously equipped on the container side with tubes which can be moved within the frame of the container. The rear wall of the distributor can advantageously be slidable in itself or consist of parts that can be assembled to different lengths, or the manifold itself can be of different lengths. As a result, the length of the distributor can be adapted to the respective work requirements.

There are inserts for side manufacturers / distributors, in which e.g. Different material must be installed in the trench at different depths at different heights. For example, In a street where a trench has been dug, the road surface must be restored. After filling the trench up to a certain height, an anti-freeze layer in the form of sand of a certain thickness must be installed. Then there is possibly a layer of 20 cm of gravel and then 15 cm of bituminous gravel and finally the wear layer at a height of 5 cm. This work can be carried out very inexpensively with the side paver / distributor by attaching metal sheets to the rear of the distributor upwards or to the side, or by attaching them firmly. This enables the different materials to be installed at the appropriate height using the side paver.

When installing wear layers, the screed of the distributor must be placed so high above the old road surface that the installed asphalt is at the same height as the old ceiling when compacted by rolling. To achieve this, spacer rails are installed at the appropriate height on the sides of the asphalt track to be installed under the screed of the distributor.

In order to keep the required distance from the tipping vehicles and possibly to push these tipping vehicles, the device according to the invention is advantageously equipped with holder and thrust spacer rollers mounted in front of the container at the level of the tipper tires. There is a multi-purpose attachment (European patent no.

092128 and German Patent No. DE 3213898). The device according to the invention can be designed so that it is part of a multi-purpose device. The container of the side paver / distributor can advantageously be designed as a loading foam.

The side paver / distributor according to the invention has the following advantages: as an attachment for loaders, backhoe loaders, excavators and tractors, it is much cheaper to manufacture than self-propelled banquet pavers and as an additional device for the DEMAG road paver. Every building contractor has a small loader as a girl for everything on the construction site. This inexpensive attachment, which can be used universally for all side distribution work, enables the entrepreneur to carry out many of his jobs more cost-effectively. Here are a few examples: Today the installation work of sand, gravel, substructure material and asphalt after digging in streets is done by tipping the material in the trench and distributing it by hand. Thanks to the loader-side paver combination that moves next to the trench, the material can be tipped into the container, conveyed into the trench and distributed there at the required height, which is much cheaper than manual installation. In the case of road surface, bike and footpath repairs, the road surface has so far been milled around the potholes or cracks and either the new asphalt material has been shoveled from the tipping vehicle into the milled tracks by hand or the material is tipped over by the tippers and then with. distributed by hand. With the device according to the invention on the loader, the material tilted into the container can now be installed in the required width and height in the milling tracks. If the loader drives next to the installed material, the tire tracks will not damage the ceiling. This method of working is much cheaper than distributing the material by hand. In the preparation of Of cycle and footpaths, the use of small road pavers is often not possible or only with difficulty because either there is no space or because the tippers must not damage the formation on the footpaths and cycle paths. In these cases, the sand, gravel, bituminous gravel and the surface course have been dumped either next to the footpath on the street or on the footpath and then distributed by hand or with small loaders. With the device according to the invention on the loader, the material is tipped on the road by tippers into the container, conveyed to the side and installed in the desired height and width. Today, unless expensive special equipment is used, which is very rare, banquets are made with the excavator. The topsoil tipped off by the tipper is brought into the correct shape with the excavator spoon. With the device according to the invention on the loader, which drives on the road, picks up the floor from the tipper and conveys it to the side and installs it there at the correct height, the manufacture of the banquets takes place much faster and more cost-effectively.

Often the cable or pipelines must first be covered with sand before the excavated soil can be refilled to prevent damage to the cables and pipelines. In the case of drainage, the excavated soil must very often not be used for backfilling at all. The trench must be filled with sand. In all of these cases, the device according to the invention can carry out this sand backfilling on the corresponding carrier device much more quickly and cost-effectively than with previous methods.

If the container of the side paver / distributor is designed as a loading shovel and the support depth adjustment device and the push rollers are attached so that they can be removed easily, and the distributor is connected to the container in an easily separable manner, for example by means of a socket and bolt connection, the Pick up dumped material from the loader with the loading shovel, drive back to the place of use, connect it to the distributor again and distribute the material

The advantage of the device according to the invention lies in the fact that with it the work listed above can be carried out faster, more rationally and more cost-effectively and with an inexpensive attachment for which there are suitable carrier devices on almost every construction site. An embodiment of the invention is shown in the drawings and is described in more detail below: FIG. 1 top view of the side finisher / distributor; FIG. 2 side view with the distributor part folded in front of the container; FIG. 3 front view of the side finisher / distributor

A container (2) is attached to the mounting plate (3), which is bolted to the mounting of the lifting arms (4), in front of a drive-steered loader (1). A distributor (5) is attached to the side of the container. The multi-purpose attachment (6) is also attached to the mounting plate. This multi-purpose attachment projects with its drive bracket (7), which also serves as a support for the container, and with the drive flange (8) into the container. The screw conveyor (10) is attached to the drive flange and to the outer limiting plate (9) of the distributor. This conveyor screw is enclosed in the area from the side wall of the container on the side of the distributor to the inner limiting plate (11) of the distributor with a tube (12). The container / distributor is equipped with a support height adjustment device consisting of a swivel castor that is adjustable in height under the center of gravity of the container, on the side facing away from the distributor (13) and two swivel castors that are adjustable in height in front of and behind the container on the distributor side ( 14). At the front of the container, two spacing slide rollers (15) have been removed in order to move the tipping vehicle to the required distance hold and possibly be able to push. La who normally only have a width of 1.40 - 1.60 m on the construction site as a girl for all existing drive-steered loaders, but the wheels of the tipping vehicles are 2.50 m apart and the loader must drive at the edge of the ditch or at the curb is the Roll attached to the side facing away from the distributor, fastened outside the track and foldable inwards. The rear wall of the distributor consists of three individual parts (16). The distributor is fastened to the container with a pivot bolt (17) and a fastening bolt (18). For transport, the fastening bolt is pulled out and the distributor is folded around the pivot bolt in front of the container and fastened there with a fastening bolt (19). The distributor can be folded up and down around the pivot point (20) with the hydraulic cylinder (21) attached to the holder (26) and the upper edge of the distributor. The sheets (22), which are adjustable in height and width, can be used to install layers of different materials at different heights in the trench. By means of rails (23) attached under the distributor, the distance between the screeds and the road surface can be adjusted so that after the asphalt has been compacted, the new and old road surfaces are at the same height. The side load is intercepted by a support rod (24).

With the distributor part folded in, the paver / distributor is transported (25).
