Description

(54) DEVICE FOR CUTTING OF TREES
one . The invention relates to the timber and woodworking industry and can be used in tree-cutting devices for cutting timber. A device for sawing without cutting wood is known, which includes a knife with a curved cutting edge and a drive for turning the knife 11. It is also known a device for sawing without cutting trees, including a flat knife mounted on a shaft with a curved cutting edge and a drive for rotating the crane in the form of a hydraulic cylinder 2. A disadvantage these devices is not high enough performance. The chain of invention is an increase in productivity. This is achieved by the fact that the cutting edge of the knife is made in the form of a segment of an involute, and the difference between the maximum and mIMmax distance of the evolvent points from the axis of rotation of the knife is equal to the maximum diameter of the tree. FIG. 1 shows the proposed device; in fig. 2 is a section A-A of FIG. 1. The device for sawing-free cutting consists of two FLAT knives fixed in the groove of the base 2. With the help of shaft 3 and J OH fggeyn 4 the knives are fixed with the base on the beam 5. The beam with the blades is brought to the tree 6 until it touches the stop 7. Work The proposed device is implemented as follows. The shearing device, mounted on the tractor's external suspension, is guided by the machine to a standing tree 6. In this case, the shearing knives 1 with the base 2 are in the open position. When the tree reaches the stop 7, the beams turn on the drive of the knives, which, when turned, produce a rerun of the tree. The cutting is carried out with the entire profile of the knife 1 having a symmetrical grinding. The knife travel is carried out from hydrocylesyls, having a flexible connection to the base of the knives. By providing complete cutting (without cross over), each knife cuts off cutting the trunk of the tree into the height, exceeding the diameter of the tree being cut. To protect the knives from seizure, they are moved with a shift relative to each other.
