Description

The invention relates to working bodies for group cleaning of trees from branches and bark and can be used as technological equipment for forest machines.

The purpose of the invention is to increase productivity and simplify operation.

5 bore holes, in which horizontal rods 6 are inserted, fixing the shanks of 3 segments of chains 4 "

Hlostovik 3 each segment of the chain 4 is made rotatable relative to its longitudinal axis and with a side notch,

Each horizontal rod 6 is made with a side chamfer 8 and is spring-loaded in the longitudinal direction by springs 9 o From one end of the horizontal rod 6 a flange 10 and a side bracket 11 are fixed, on the other - a flange 12 and a thrust nut 13 "are fixed at the end of the rotating body 1 stops 14 with recesses 15 for placing the ends of the side brackets 11 o The side bracket 11 may be provided with a handle 16 Along the edges of the rotating body 1, annular rims 17 may be worn

The working body works as follows

In the transverse holes 2 of the rotating housing 1 install the shanks of 3 segments of chains 4 o Horizontal rods 6 are rotated while

engine (not shown). When mounted on a logging machine, rotating body 1 with segments of chains 4 can be on top and on its sides is closed by a housing

When the machine is in operation, body 1 rotates around the longitudinal axis together with segments of chains 4 and when moving it relative to the trees being cut, segments of chains 4 strike the branches of the tree and the outer surface of the trunk, clearing the trunk of boughs and measles

If it is necessary to replace the broken lengths of chains 4, the rotating body 1 is turned upwards so that the corresponding shank

3 was directed upwards. Then turn the corresponding horizontal rod 6 by 180 °, release the lateral recess 7 of this shank 3 from fixing (FIG 4), remove it from the longitudinal hole 5 and put the new chain into working position (Fig. 3) „

This construction reduces the time spent on the installation of segments of chains.

as shown in fig „4, with this

side chamfer 8 is directed towards these shanks 3 and side notches 7 of shanks 3 of the corresponding row do not overlap with horizontal rods 6 o Then the corresponding horizontal rod 6 is rotated 180 ° (FIG 3), while its side chamfer 8 is directed in the opposite direction from the shank 3 and the horizontal rod 6 overlaps the side recesses 7 of the shank 3, fixing the lengths of the chains 4 in the working position Ho The reliability of fixation is ensured by the fact

that the horizontal rod 6 is re-energized, and each horizontal is stern, and the side bracket 11 has a side chamfer, is rotatable relative to its longitudinal axis, spring-loaded in the longitudinal direction and provided with a side bracket fixed at one end, and to accommodate the ends of the brackets.
