Definitions

  • the invention relates to with own power source equipped remote controlled working machine, the ground clearance and wheelbase of which can be regulated and which is because of its charac ⁇ teristics suitable for harvesting in a forest.
  • a longitudinal telescope frame is used as help in a difficult terrain, in which case one of the axle systems of the machine can be pushed forward by lengthening the thelescope frame other axle systems being in their place, analogously by shortening the frame can the latter axle systems be pulled the previous one staying in its place.
  • the most important advantages of the invention can be conside ⁇ red the accomplishment of a working machine with advantageous purchase price, which has good moving abilities in a difficult terrain, wide range of functions and small own weight.
  • Espe ⁇ cially applied to harvesting the working machine according to the invention can almost in every case be driven beside the tree, we can do with it the felling and delimbing and other necessary cuts and also transport timber.
  • With the new type of wheel support the working machine can be set to a horizontal position also on a sloping ground.
  • Figure 1 presents the reducted frame construction of the wor ⁇ king machine.
  • Figure 2 presents the frame laid down.
  • Figure 3 presents the working machine seen from the front.
  • Figure 4 presents the working machine from the front the frame laid down.
  • Figure 5 presents the working machine from the side with an extra device.
  • Figure 6 presents the working machine from the side the extra device turned.
  • Figure 7 presents the working machine seen from above.
  • Figure 8 presents the working machine with another extention.
  • Figure 9 presents the working machine according to figure 8 laid down.
  • Fig. 1 presents one example of the reducted frame construction of the working machine according to the invention.
  • the working machine has four wheels 1, each of which are connected to arms 2.
  • Arms 2 have been jointed to the frame part 4 so that every four arms has own shaft 15.
  • a cylinder 3 the example having two pieces, one on each side, arms 2 are turned, when a certain ground clearance or wheelbase is wanted. Cylinders on both sides are controlled separately. With this arrangement can the working machine easily be straightened on a sloping ground. So the side tilt of the working machine can be compen ⁇ sated.
  • the arms 2 f.ex. on the side being seen in figure can be with a separate shaft mechanism forced to turn in regard to the frame part 4 always the same amount although only one cylinder 3 is being used.
  • Frame part 4 is mostly crosswise in the middle of the working machine and to it is connected a power plant, a hydraulic unit, controlling devices and the actual tools and extentions.
  • the distance between shafts can be varied and they can even be united in the middle to be the same shaft point.
  • the regulation of the ground clearance and the change in wheelbase happens always at the same time.
  • Fig. 3 the working machine being seen from the front is in the highest position as to its ground clearance and to it has been connected a harvester extention 5.
  • the extention 5 there is cutting and pruning end 6 as well as arms 7 to catch the timber.
  • the cutting down happens at different heights simply by bare regulation of the ground clearance when the working machine has been steered to the base of the tree.
  • the extention 5 is fastened to the frame part 2 to turn upon the horizontal axis so that the extention turns on and below the frame. In both of these positions of the extention the timber can be transported by the working machine.
  • Fig. 4 the frame of the working machine has been laid down to timber cutting position. With cutting device 6 at the harvester end the tree is cutted down at the wanted height usually as low as possible. The working machine is at the moment of cutting down steady, because the wheelbase is then largest.
  • Fig. 5 the working machine is presented from side in fell ⁇ ing situation. From the figure is being seen that the front wheels of the working machine are located even on the other side of the tree being cutted down than the working machine itself. The working machine is steady and can then do a controlled cutting down even if it is a question of bigger trees. Together with the frame part 4 of the working machine is presented a power plant and a unit 8 including hydraulic machinery.
  • Fig. 6 is presented the harvester extention 5 turned over the frame part 4.
  • the tree cutted down is turned controlled with the support of catching arms 7 over the working machine. In this position are done the pruning and cuttings.
  • a feeding device like rotating rollers, which carry the timber according to timber direction while pruning cutters delimb branches.
  • Fig. 7 the working machine is presented from above. Wheels have hydraulic hub motors 9, with the help of which also the steering of the working machine happens by braking the engines on the turning side. Rail width is such that the harvester end 6 has space to work and move in the room between the wheels 1 and the arms 2.
  • Fig. 8 presents another form of harvester accessory.
  • To the frame part 4 is attached also for timber transportation suitable with side poles 10 equipped space.
  • Harvester part 14 is connected to the end of boom system 11 and the tree is cutted down with this device the same way as with known harvesters.
  • At the harvester end there are transfer rollers 13 and delimbing cutters 12, which function also as support arms.
  • the harvester end can be turned 180 degrees, which enables f.ex. taking a horizontally lying timber from the ground, lifting and turning the timber to loading space from upside.
  • the tree is cutted down away from the working machine and deli bed the boom 11 lifted up so high that the trees go through delimbing cutters 12 directly to loading space.
  • the harvester part 14 is then hanging down from the boom 11.
  • the working machine In Fig. 9 the working machine is in felling position the frame laid down. With the device can even bigger trees be felled if the trees are always felled away from the working machine and the support is loosened during the felling.
  • the steering of the working machine goes most conveniently by using remote controllers.
  • the controlling person has then a good view to any direction and building of a cabin in the working machine can be avoided.
  • the working machine could't be accomplished advantageously if a steering cabin should be placed in it.
  • Working with this working machine is no more dangerous than using a chain saw, because a falling tree must be looked out in both cases.
  • the working machine is safer in that way that with it can hung trees be loosened from an appropriate distance.
  • the working machine is therefor also well suited for harvesting in storm destruction area.
  • For wheel support has been developed a progressive way, which gives the working machine a good stability, the fixing of tilt can be done according to terrain and stucking can be avoided.
  • a combustion engine having appr. 30 kW effect.
  • a hydraulic system for power transmission is used a hydraulic system, with electrically working valves, and remote control ⁇ ling functions in the known way.
  • Moving of the working machine can be remarkably improved by installated half bands, the support wheel of which is instal- lated in front of the front wheels and connected to an arm 2 so that the support wheel is lowered to the level of the real front wheel 1 when the arm 2 is turned to the shortest position of wheelbase.
  • This is a driving position in a soft country. Accordingly by lengthening the wheelbase the support wheel rices higher and helps in crossing the obstacles.
  • Rail width can be regulated in one form of the performance by regulating the distance between fastening points of the arms 2 in frame 4.
  • the working machine according to the invention is especially well suited to be in a terrain moving piledriver, drilling machine, at the roadside moving working machine, in which case it is not as a slow machine in the way on driveway as well as a.o. it is suitable to mines and as a working machine with an excavator or a bucket loader equipment.
