The invention relates to the timber and woodworking industry and can be used in delimbing machines.

A working part of the delimbing machine is known, which has a body with successively located front and rear blades and a window for cutting wood 1 with a rear knife.

However, the design of this tool is effective when cutting branches, but it does not provide the splicing required to speed up the drying of fine-sized wood to be alloyed.

Also known is the working body of the tensile machine. The housing consists of consecutive front and rear knives, one of the knives is U-shaped with a radius of a circle at its top equal to 3-10 cm, and the other knife is flat and parallel to chord of the arc of a circle of the U-shaped knife 2.

This working body has advanced technological capabilities, as it additionally provides for thinning of thin wood, which is subject to alloying. However, the drawback of the knife design is that the quality of the glade decreases sharply in the summer, because the window for removing the cut wood is constantly clogged with bark and chips, which significantly improves the performance of the tool and performance.

The aim of the invention is to increase productivity.

This goal is achieved by the fact that the working body of the delimbing machine, containing its body with consecutive front and rear blades, one of the blades made LI-shaped with a radius of the arc of a circle at its apex 3-10 cm, and the other blade - with a flat cutting edge located parallel to the chord of the arc of a circle, a knife with a flat cutting edge mounted on the body of the working body with the placement of its cutting edge in front of the cutting edge of the U-shaped knife, while the flat knife is made in the form of a l-shaped lever, one of the balls which is fixed to the working body housing and the cutting edge of the flat

the knife is made on the kolsolny end of the other lever arm.

FIG. 1 schematically shows the worker

organ, side view; in fig. 2 - the same view

from above; in fig. 3 shows section A-A in FIG. one.

The working body consists of a body made in the form of a plate 1, having a U-shaped profile and fixed to the holder 2. / Along one longitudinal edge of the plate 1, the rear knife 3 is fixed with the cutting edge a, in this case the cutting edge of the knife 3 is the leading edge plates 1. The front knife 4 with a flat cutting edge b is made in the form of an L-shaped lever, one of the shoulders 5 of which serves as a platform for fastening it by bolting through the holder 2 on the body, and the cutting edge b is made on the cantilever end of the other shoulder 6 lever and placed in front of the cutting edge and the rear knife 3. The knife 4 is attached to the holder 0 2 with the possibility of its height adjustment by installing gaskets under the knife.

The working body works as follows.

Before the tree is pulled by the delimbing machine, the working body is pressed against the surface of the trunk. The drag in this case is carried out by the tip forward. When a tree is pulled through the working unit by means of the front knife 4, a spider search is performed with simultaneous cutting of the boughs that fall in its path, and the back knife 3 cuts the bulk of the branches.

With further pulling of the tree as the diameter of the trunk increases in the direction of the butt part, for example, up to 20 cm, the knife 4 is disconnected, i.e. it is cutting, the edge b comes out of contact with the surface of the tree trunk, and further pruning occurs without splitting the trunk.

Thus, the proposed working body of the delimbing machine provides for mechanized prolyushka of tree trunks at the same time as cutting branches, and without sacrificing productivity and quality of piercing in the summer period, since the bark and

chips are freely removed from the front knife.

Claims (1)

A WORKING BODY OF A TARGET MACHINE, comprising a body with successively located front and rear knives, one of the knives being U-shaped with a r.adius of a circular arc at its apex of 3-10 cm, and the other knife with a flat cutting edge parallel to the chord of the arc a circle, characterized in that, in order to increase productivity, a knife with a flat cutting edge mounted on the body of the working body with the placement of its cutting edge in front of the cutting edge of a U-shaped knife, while the flat knife is made in the form of a L-shaped ychaga, one arm of which is fixed to the working body housing and the cutting edge of the knife is formed flat on the cantilever end of the other lever arm.
