(54) METHOD FOR TREATING FOREST MATERIALS AND MACHINES FOR ITS IMPLEMENTATION

t. -.

FIELD OF THE INVENTION The invention relates to the timber and woodworking industry and can be applied in the lines for debarking and splitting timber.

There is a method of processing timber, including moving and splitting 1.

The disadvantages of this method are increased energy consumption during splitting and the impossibility of subsequent debarking.

There is also known a method of processing timber, including their movement, debarking and splitting (2J.

However, this method is associated with increased energy intensity.

In order to implement this method, a machine is known that includes a frame with piercing bodies mounted thereon, a receiving tray and a pressure plate with its drive 1.

The purpose of the invention is to reduce energy consumption.

This is achieved by debarking and splitting at the same time as the timber is moved. In addition, in the machine for registration of the proposed method before

To destroy the bark, split woods, located coaxially with timber.

Figure 1 shows the machine for

5 implementation of the proposed method of working & timber, side view; figure 2 is a view along the arrow. And figure 1; in fig. 3 shows a section BB in FIG. The machine includes a frame 1 with piercing organs mounted on it,

"Made in the form of a cruciform

supports 2, on branches of which

using sliders 3 installed

radial 4, horizontal 5 and

15 vertical 6 splitting wedges, as well as arc-shaped knives 7 and 8 in the shape of trays. Bearing 2 has a recess 9 in the middle part, in which the wedge-shaped knives 10 are installed.

20 Each of the sliders is provided with a hydraulic cylinder 11 of its reciprocating movement, the body of which is fixed on the branch of the support, and the rod 12 is connected to the slide at

25 bracket support 13. To place the timber (churak) to be cracked and chipped. (cutting) a rotten or middle part out of it

the puncture wedge and arcuate knives are made by a pressure plate 15 with a cylinder 16,

The coaxially pricking organs and between them and the receiving chute 14 are fixed on pc1me 1 by means of support 17 organs for destroying the bark of uncooled timber, made, for example, in V11de rotary hollow spring-loaded elements 18 nozzles 19 installed evenly around the circumference on the hollow ring holder 20, which reported to the working environment.

The organs for crust destruction are fixed on the receiving tray and made in the form of a hollow ring collector with openings on the inner side for the passage of jets of the working medium.

On the receiving chute 14, a mechanism of preliminary action on the bark of the split timber is mounted, made in the form of spring-loaded 21 ties 22 rollers 22 with knives 23.

The machine works in a perceptive manner.

During the working stroke of the ram cylinder, the 16-timber (churak) 24 fed to the splitting receiving tray 14 is pushed by an anvil plate 15 between the spring-loaded rollers 22 that enclose the splitting churak and cut (cut) and partially blasted the knives 23. Upon further thrust, the churak encounters nozzles 19. At this point, nozzles 19 are supplied (by a known method) under pressure to working nozzles 19 through a ring holder (collector) 20 (for example, compressed air with wood or metal sawdust, liquid, etc.). ), as a result of which there is an intensive destruction and partial or complete removal of the bark from the surface of the block around its perimeter. This removes the mineral impurities (sand, pebbles, etc.) contained in the crust.

Continuing to move, the blockage is pressed against the vertical B and horizontal 5 wedges, and then it encounters arcuate blades 7 and 8 mounted on a certain diameter of the rot or the middle part of the block, which are inserted into the latter.

With the further advance of the blockhead, knives 7 and 8 puncture (cut out) the middle part (rot), and knives 10,

sharpened under the wedge, rakskshvyvayut middle part (rot) churaka.

The peripheral part of the block is cleaved by wedges of vertical and horizontal sliders into four parts. If necessary, a churak can be split into two, four, six or eight parts. To do this, combine the center of the corresponding group of piercing organs with the center

® Churaka.

With an appropriate pressure of the working environment, complete destruction of the bark and sufficiently clean debarking of lumber pulled onto the stabbing organs, including measures of evil lumber, is provided, which is largely due to the preliminary incision of their bark with knives 23 of the rollers 22.

The bark covers every churak,

0 to form a solid closed shell (armor), due to the destruction (and removal) of the bark of timber before the thrust and in the process of thrusting sharply on piercing organs

5 the splitting forces are reduced and

the energy intensity of the splitting process, which reduces the metal consumption of the machine for splitting timber. Besides,

The Q energy consumption is also reduced by using one movement of timber at the same time for two operations: for debarking and splitting.

Claims (2)

1. A method of treating aloe forest mat, including their movement, debarking and raskoshshivanie, about the fact that with the aim of reducing energy intensity, debarking and splitting are carried out simultaneously with the movement of timber. 2. The machine according to claim 1, comprising a frame with stabbing installed on it organs, a receiving tray and a ngikimnaya plate with its drive, which is connected with the fact that organs are placed in front of the piercing organs to destroy the crust timber located coaxially timber.
