Onion harvester with leaf topper US Patent:US20040216441A1

An orientation system for vegetables includes a plurality of rotating rollers that both pull the vegetable into an inverted position, with leafy top down, and advance the vegetable along the length of the rollers to deliver the vegetables to a cutting system. The orientation system may be included in a vegetable harvester and topper or may be used separate from the harvester vehicle. The orientation system preferably has a plurality of orientation roller pairs, made up of first and second counter-rotating orientation rollers. These rollers may include strips of elastomeric fingers or other protrusions that engage the leafy top and pull it downward. Preferably, one of the rollers may also have a vegetable advancing spiral that moves the vegetables in “auger-style” by pushing the vegetables along in front of the rotating spiral. These rollers deliver the vegetables to the cutting system in the inverted position, so that the leafy top, when cut off, falls down to a trash removal system and the vegetable roots/bulbs' momentum carries them past the cutting system into another portion of the harvester for further processing or collection.

Similarity between this machine and my invention is in cutting and removing onion stems; however, the mechanism of this action in my invention is different in that when the onion stem reaches the rollers, involved between horizontal wire of second chain and rollers and onions are suspended in the air and then cut by the razor.

Mechanical harvester for harvesting bulb crops US6484810B1

A mechanical harvester for harvesting, topping and sacking bulb crops, such as onions. The harvester extracts the onions from the ground and transports them rearward to a cutting assembly by conveyor systems that drop out small onions, dirt, rocks and debris. The cutting assembly comprises a set of elongated cutting blades positioned to cooperatively accept and sever the leaves and roots from the bulb. The offal drops away from the harvester to the ground by manner of gravity. After cutting, the onions are transported through an inspection assembly for inspection, sorting, grading and further distribution. The onions are then transported rearward to a sacking assembly for placing the onions into sacks, to a chute device returning the onions to the ground or to a conveyor system transferring the onions to an adjacent vehicle. Platforms on the sides and ends of the harvester facilitate the above operations.

This invention is a complete harvesting system, soil separator, stem cutter, grading and transferring to storage location; however, in my machine there is only the operation of soil separation and stem cutting on a smaller scale, which design and operation of the other mentioned steps in this invention are also different from mines.

Root-crop harvester with recirculation mechanism-US7789166B2

A root-crop harvester is configured to temporarily store tubers by recirculating tubers on the conveyor system of the harvester. The conveyor system has selectable first and second operating configurations. In the first operating configuration the conveyor system transports tubers from the digger bed to an outlet where tubers are unloaded from the harvester (e.g., onto a truck). In the second operating configuration the conveyor system transports tubers along the conveyor system for a period of time and then diverts tubers to an earlier position within the conveyor system, thereby recirculating tubers on the harvester. After a period of time, the harvester operator selects the first operating configuration and the recirculating tubers along with newly dug tubers are unloaded from the harvester.

In this invention harvesting crops is done rotatory from inside the soil; however, in my invention the onion comes straight out of the soil and the next step the process of separating soil, clods and cutting stem, which is different with this mentioned invention.

Mechanized harvesting machine with rotating picking elements-US Patent: US6338236B1

A harvesting machine particularly suitable for picking or harvesting vegetables, such as peppers or tomatoes, employs a harvesting frame on which is mounted a rotating shaft aligned transversely to the direction of movement of the machine. A pair of spaced apart picking members are mounted on the shaft on opposite sides of a row of plants having a crop to be harvested. The picking members are simultaneously rotated; and each of them has a plurality of arcuate picking elements pivotally mounted on them. The picking elements rotate with the picking members in the same direction of movement of the machine; and as the picking elements rotate downwardly above the row of plants, a cam pivots them into a position adjacent the picking members, spaced away from a plant located between the picking members. As the machine passes over the plant, the picking elements are moved by a second cam into a position to extend into the space between the picking members to engage the plant to be picked and remove crop therefrom for deposition onto a conveyor for removal from the machine.

This invention is for harvesting different types of vegetables, which arrange herbal products via special embedded parts and are ejected from machine by the conveyor. This invention is related to my design for the purpose of construction and service; however, about mechanism and structural properties are quite different.

The mentioned invention is about a complete large-scale harvesting system, for example beetroot, which removes the plant from earth cleanly and without damage on the band and conveyor and transfer to the storage compartment. This invention has a different mechanism and is aimed to harvesting of mass product, my invention is in smaller dimension to harvest onions and this plan applied to farmers.

This invention is called an onion harvesting machine with the capability of cutting stems and separating clods and stones, by attaching and carrying via tractor, no need for transplanting machine, which is applicable to all agricultural lands. The components of this machine include parts related to the onion harvesting part, the mechanism of onion-stone clod separator and the mechanism of onion separation from the stem is as follows: Gears, shafts, hands connected to the tractor, front blade, downpipe, chains, plastic horizontal strips, rollers and cutting blades. As mentioned, this machine is attached to the back of the tractor and connected to the tractor power transmission arm that the power of this machine is provided via tractor PTO.

Core and the main part of the machine are made of three separate chains that rotate in one cycle and simultaneously. The role of the upper chains is separating objects larger than 14 cm. After filtering large objects and clod, the onion is dropped to the onion is dropped to the bottom of the machine or on the lower chain. The onion stem lies between the middle and upper chains, when the onion stem reaches to rollers, involved between horizontal wires of second chain and rollers and onions are suspended in the air and then cut by the razor. This machine cut variety of onion stem in any size with a distance of 2 to 3 cm and at one height and harvests a crop without soil - clod and healthy.

Harvesting crops traditionally and man-power is incompatible with today's conditions of agriculture and food production in the world. In fact, it is not possible to use heavy agricultural machinery to harvest crops for all farmers because of the high cost of buying and renting this machine. Accordingly, design and construction of a high-capacity onion harvesting machine and low construction cost has been applied to different agricultural lands has been carried out.

In other similar devices, it is not possible to cutting stem and complete separation of soil-clod and stone, but this device does not require transplanting device in addition to the above facilities having the above facilities as well as the design of the device is in such a way that It also has the potential of technically upgraded in order to become an independent controlled farming machine. The purpose of this invention is to provide an onion harvesting machine to speed up the harvesting process that reduces human intervention and increased production efficiency, resulting in a high quality product and low discarding.

The present invention is an onion harvesting machine with the capability of cutting stems and separating clod and stone. This machine attaches to the bottom of the tractor and when the onion harvesting process begins, first, the tractor pushes the front part of machine into the ground then move forward, the front razor sinks into the soil about 20 to 30 centimeters and because the device is moving forward, onion with soil, stone and clod moves to the end of the machine, which is the main part through chain strap, which draws its propulsion from the hydraulic and embedded engines behind the device. while the onion is rising from the front of the machine, all small stone and clod, which their diameter is less than 3 cm, during this step, as it rises from the band, it falls to the ground and is separated from the onion.

After the onion are raised up, clod and stone at the bottom of the device front band are poured into the central and main part of the machine, the main part or the main core of machine consists of three separate chains that rotate in one cycle and simultaneously. The task of separating chains of objects greater than 14 cm by means of wires that are connected at a distance of 14 cm horizontally to the chain wings, below the mentioned chains, the wires are mounted vertically and fixed at 14 cm intervals, which cause the upper chains to act as a filter and prevent objects larger than 14 cm from being thrown into the machine and because the chains are moving backwards, all the big objects fall on the ground from the end of the device.

After filtering the large objects, onion and objects under 14cm are poured into the machine, the second chain or the middle chain has a structure similar to the upper one with the same horizontal and vertical wires, both chains move at exactly the same speed and they are moving exactly the in same direction about 30 to 40 centimeters is far from high chain, the middle chain has several pieces (rollers), which are at the bottom of this chain and on top of the machine razor, this rollers exactly the same speed of chain are spinning through gears that fitted on the middle chain.

When onion and clod are poured to the bottom of the main part of device or on the lower chain, the onion stem is placed between the middle and upper chains; because all three chains are moving at the same time, onion and clod are also moving inside the apparatus, when the onion stem reaches the rollers between the horizontal chains of the second chain and the rollers are involved and the onion is suspended in the air.

In this way, the onion continues to move until it reaches the blade of the machine. The blade is mounted just below the second chain with adjustable spacing, which is driven by a hydraulic-motor; when the suspended onion in the air reaches to blade, the blade cuts stem and separates it from the onion; after the onion is cut from the stem it falls on the horizontal strip that there is behind the chain and comes out of the machine. The mentioned horizontal strap is made of soft plastic, which its mover force is a high-speed hydraulic motor and 2 cycles. Horizontal band via a metal sheet divided into two parts, which transfer onions and clods apart from each other to outside of the device separately.

Because of the fact that clods and stones are without stem and do not involve with rollers, therefore, they are poured to the first section of the horizontal strip and transported outside the machine, the beneath chain is at the same speed of the superior chains and the distance to the middle chain is adjustable depending on the onion and the ground, however as a result of onion stem involve with rollers and are suspended in the air with the help of rollers, transfer to the end of the device and after cutting the onion stem, to the second part of the horizontal band(plastic) has poured, which is without stone and clod and are individually driven out of the machine. Stems cut by the machine razor move to the end of the middle chain as they involved rollers and horizontal wire chain and between the middle chain and the upper chain are leaving that distance between the two chains is about 40 cm, then among the horizontal wires of upper chain are poured out of the machine easily and without any hassle.
