Description

The invention relates to devices for pruning and debarking timber and can be used in the timber and woodworking industry.

A device for cutting branches from fallen trees is known, which contains a cutting body in the form of a milling cutter, on the surface of which a screw c is fastened between the cutting elements, limiting the depth of cut 1.

The disadvantage of this device is the impossibility of debarking the trunk during pruning. In addition, the longitudinal movement of the trunk in the process of cutting limbs limits the performance of the device. When using this cutter, it is impossible to change the thickness of the layer being cut depending on the length of the tree.

A device for cutting branches and debarking timber, including a frame, a working body in the form of paired drums with springs located on them along a helical line, pivotally interconnected by tape cutting bodies 2.

However, the known device does not produce debarking during pruning due to the lack of control of the depth of the cut bark layer. This necessitates additional equipment for debarking after pruning.

The purpose of the invention is to expand the technological capabilities of the device.

The goal is achieved by the fact that in a device for cutting branches and debarking of timber, including a frame, a working body in the form of paired drums with spring-loaded springs, pivotally interconnected by tape cutting bodies located on them, are provided with equal distances from each other. other limiting elements, filled in the form of rings installed on the slide supports with conical working surfaces, the line passing through these working surfaces being forming a cone with a taper of 1 / 500-1 / 1500.

FIG. 1 shows the proposed device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - the same, option

performance; in fig. 4 shows a section BB in FIG. 3

Devices for cutting branches and debarking timber contains a frame 1, on which 5 an actuator 2 is installed and paired drums 3 fitted with helix-mounted spring-loaded pivotally connected tape-cutting members 4. The drums 3 have limiting elements 5 which are made in the form of rings 6, installed in the supports 7 slip. The rings 6 of the restrictive elements 5 can be made detachable and consist of two half-rings 8 interconnected with a gasket 9 and a bolted connection 10. The slide support 7 is made detachable, consisting of three inserts 11. The side surfaces of the rings 6 of the restrictive elements 5 They are made with conical working surfaces that fit into an imaginary cone with a taper of 1/5001/500, which corresponds to the thickness of the bark of the tree in the apex and butt part of the tree. The supports of the restrictive elements 5 are installed with uniform pitch.

5 The device works as follows. The tree is placed on the drum 3 and the drive 2 is turned on. The drums 3 rotate towards each other, dragging the tree, which with its own weight sinks the spring-loaded pivotally connected parts of the cutting bodies 4 and rests on the limiting elements 5. At the same time, the cutting bodies 4 with simultaneous cutting of branches produced and debarking. The thickness of the cut bark chips corresponds to the difference in diameters of the rings of rings of the restrictive elements 5 and can be adjusted for different breeds by a set of interchangeable restrictive elements 5. The tree, rotating, is gradually processed by poliosti, then it is discarded and the cycle is repeated.

0 The proposed design makes it possible to carry out simultaneously with tree clearing of branches and debarking, transverse feeding in the proposed device reduces the processing time of one tree, increases the productivity of the process equipment and reduces the number of workers.
