Technical field

The technical solution relates to a device for woodless cutting of wood.

BACKGROUND OF THE INVENTION

There is a very rapid development of science and technology in the world, which is connected with the development of production, which results in an increasingly intensive acquisition of natural resources. In order to ensure the rational management of forests, it is necessary to use more and more modern techniques of logging, which would bring less and less waste generation in shading of trees and trees.

Several solutions are known from the prior art for cutting leafless wood.

For example, CN 208196940 (U) -2018-12-07 is the utility model of QINGDAO RUNJIA YUYAO PLASTIC MACHINERY CO LTD Applicant, which describes a vertical bladeless cutting machine, including its fixed station. The undersides of the fixed station are all equipped with supporting legs. The wall of the station is equipped with a photoelectric switch, which is equipped with a roller at a fixed station, and the upper part of the roller has a conveyor belt. The cutting blade is equipped with six cutting blades with a blade thickness of 0.6 mm. The problem with the machine is that the cutting speed is slower.

CN107599072 (A) - 2018-01-19 “Applicant's Chipless Cutting Saw by YANTAI CHUNLJN ACRICULTURAL MACHINERY AUTOMATION CO LTD describes a bladeless saw that is capable of performing bladeless sawing. The machine consists of a saw, a hydraulic station and a hydraulic cylinder. The hydraulic station is fixed at the bottom of one side of the tail end. The hydraulic cylinder is hinged to the top of the tail end of the cutting saw through the mounting bases. The stand and the hydraulic station are connected to the hydraulic cylinder The bladeless saw improves work efficiency, and it is advantageous that sawdust is not generated during machine operation.

One possible solution is the use of leafless wood splitting in the actual logging. Woodless log splitting in the forest harvesting process is mainly used for machines intended for tree branching. Increasingly, however, flapless wood splitting is used in the form of flapless shading heads for single-operation stands. The disadvantage of modern flapless shading heads is the use of a straight cutting edge along with a rectangular type of cutting.

The essence of the technical solution

These drawbacks of the prior art are overcome by a device according to the present invention, which is based on the use of a saw-like cutting edge of a shielding knife and an angular type of cutting. This configuration can reduce the cutting force required to split the wood by up to 60%.

This solution increases machine efficiency thanks to the innovative shape of the cutting edge of the shielding knife.

The flapless timber splitting device comprises a timber splitting blade, which is inserted between the front and rear fasteners in a portion of its base, and is firmly fastened between them by a screw connection with hexagon socket head screws from one side and hexagon nuts from the opposite Party.

The cutting portion of the shielding knife 1 has a saw-shaped cutting edge cut out in a V-shape for cutting with an angular contact

Attachment of the shielding blade by means of grips allows it to be quickly replaced in case of damage or wear.

This technical solution will increase the efficiency of the device, simplify service of the device and reduce the cost and cost of the device.

Thanks to the grips, the cutting tool can be easily replaced when it is worn, making the machine economical

An exemplary embodiment

Example 1

The technical solution is explained in more detail with the help of figure 1, which shows the constructional solution of the device for woodless cutting of wood. Figure 1 shows two isometric views of the design of the device.

The device consists of a shading knife 1, which carries out the wood splitting process, a front grip and a rear grip 3, which ensure easy replaceability of the shade blade 1 in case of damage to it, or in case of sharpening of the blade due to wear of cutting edges.

The flapless wood splitting device of FIG. 1 comprises a wood shading blade 1 which is inserted in part of its base between the front grip 2 and the rear grip 3 and is fixed therebetween by a screw connection by means of cylindrical hexagon head screws 4 on one side and hexagon nuts 5 from the other side.

The cutting part of the shielding knife 1 has a saw-shaped cutting edge cut out in a V-shape for cutting with an angular contact

The front grip 2 has an L-shaped cross-section with both its perpendicular arms comprising openings, and the rear grip 3 has a rectangular shape with openings, and the number of openings and their arrangement is the same for the front grip 2 and the rear grip.

The shearing knife 1 in FIG. 1 is fastened to the brackets by means of five hexagon socket head screws 4 with five hexagon nuts 5 from the opposite side.

Industrial usability

Equipment for leafless wood splitting is designed for leafless wood splitting in the forest shading process.
