Technical field

Technical solution of a piece of equipment for chipless wood cutting.

Prior art

There is a very rapid development of science and especially technology in the world, which is also related to the development of production, which results in an increasingly intensive extraction 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 with them less and less waste generation during the shading of trees and trees.

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

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

CN107599072 (A) -2018-01-19 Applicant's "Chipless cutting saw" by YANTAI CHUNLIN AGRICULTURAL MACHINERY AUTOMATION CO LTD describes a chipless cutting saw capable of chipless wood cutting. The device consists of a cutting 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 suspended from the top of the tail end of the cutting saw via mounting bases. The stand and the hydraulic station are connected to a hydraulic cylinder. The chipless cutting saw improves work efficiency, and it is advantageous that sawdust is not generated during machine operation.

One of the possible solutions is the use of chipless wood cutting in the actual logging. Chipless wood cutting in the forestry process is mainly used for machines intended for machine branching of trees. Increasingly, however, chipless wood cutting is used in the form of chipless shading heads for single-operation stands. The disadvantage of modern chipless shading heads is the use of a straight cutting edge together with a rectangular type of cutting.

The essence of the invention

These shortcomings of the prior art are eliminated by the device according to the present solution, the essence of which consists in the use of a saw-shaped cutting edge of a shielding knife and an oblique type of cutting. This configuration can reduce the cutting force required to divide the wood by up to 60%.

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

The chipless wood splitting device comprises a shading blade for splitting wood, which is inserted in part of its base between the front bracket and the rear bracket, and is fixed between them by a screw connection by means of socket head cap screws on one side and hexagon nuts on the opposite side. parties.

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

Attaching the shielding knife with the help of handles allows its quick replacement in case of its damage or wear.

This technical solution will increase the efficiency of the device, simpler service of the device and reduce the economic complexity of the device.

Thanks to the handle, the cutting tool can be easily replaced when worn, making the device economically advantageous

Examples of embodiments of the invention

Example 1

The technical solution is explained in more detail with the aid of Figure 1, which shows the design of the pie-chipless wood cutting device. Figure 1 is two isometric views of the design of the device.

The device consists of a shading knife 1, which performs the process of cutting wood, further a front holder 2 and a rear holder 3, which ensure easy replacement of the shading knife 1 in case of damage or in case of necessity of sharpening due to wear of cutting edges.

The chipless wood cutting device according to FIG. 1 comprises a shading knife 1 for dividing wood, which is inserted in a part of its base between the front holder 2 and the rear holder 3, and is fixed between them by a screw connection by means of screws 4 with a cylindrical head with an internal hexagon on one side, hexagon nuts 5 from the opposite side.

The cutting part of the screening knife 1 has a saw-shaped cutting edge cut in the shape of a letter V for cutting with oblique contact.

The front bracket 2 has an L-shape in cross section, both of its perpendicular arms having holes, and the rear bracket 3 has the shape of a rectangle with holes, and the number of holes and their arrangement are the same for the front bracket 2 and the rear bracket 3.

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

Industrial applicability

The chipless wood cutting device is intended for chipless cutting of trees during the process of shading wood in forestry.
