The invention relates to the forest industry and can be used in the treatment of fallen trees.

The aim of the invention is to provide the possibility of processing comic and twisted trees.

FIG. 1 shows a machine for pruning knots from fallen trees; jS 4moment pruning pruning; figure 2 - the same, when triggered, the receiving head during the capture of zakomelistogo tree

The machine for pruning knots from fallen trees contains a self-propelled chassis 1, on which column 2 is mounted on the latter by means of an axis 3 rotatable in a vertical; the beam 4 is fixed on the ground plane; movable, 6 and one fixed 7 delimbing knives. At the rear end of the beam, the receiving head consisting of the body 9 and the pivoting levers 10 (lever drive conventionally not shown) is pivotally fixed by means of the axis 8. A rotation limiter 11 is installed between the beam and the body 9, the receiving head. On the housing 9 by means of an axis

12 installed block 13, the axis of which is located below the axis 8. The machine’s pulling device consists of a winch 14, cable 15, blocks 13 and 16, and a pulling mechanism which consists of a trolley 17, swivel clamps 18, and a cable block system containing cable 15 and blocks

13 and 16.

The pruning machine works up to the following.

By tilting the beam 4 and lowering the knives 6, the next tree is captured. By turning around axis 3 together12423702

14, trolley 17 is driven to the shaft. With the clamps 18 closed, the tree is pulled through delimbers 6 and 7. After the passage between the open levers 10, the last bones are held to support the tree. Then the trolley-17 with the clamped clamps 18 goes back to the gripping bark head 5 and pulls again the tree through the closed knives 6 and 7 for the length of the beam and so on until all the boughs are cut off on the tree. If, due to the large zakomelistost I.PI, the curved trunk does not pass between the open levers 10 and hits one of them, then the result of iner force uu moving luminant wood and traction about taskivayuschego the receiving mechanism head is rotated about an axis 8 definiteness angle. If the butt comes off the lever 10, then the body 9 under the action of the resultant R tension of the tro 15, the elastic force of the cable resulting from the difference in the lengths of the descending and rolling branch of the cable and also due to the weight of the receiving head will turn back to the stop 11 and Further processing of the tree is proceeding as described. If the butt does not come off the lever 10, the dragging will stop without breaking the levers 10, as it is removed by turning the receiver head. When the clamps-18 are opened, the butt will fall down, and with the subsequent rotation of the body 9, the beam 4 and the levers 1, it will rise to the working position and processing will continue.

Thus, due to the use of a barn-mounted receiving head, the possibility of a floor of levers is eliminated and the longitudinal axes of the tree are ensured and the processing of curved trees,

14, trolley 17 is brought to the butt of the tree. With the clamps 18 closed, the tree is pulled through the delimbing knives 6 and 7. After the passage between the open levers 10, the latter are reduced to support the tree from below. Then, the dolly-17 with the diluted clips 18 returns to the gripping-knot-knob-cutter head 5 and again pulls the tree through the closed knives 6 and 7 for the length of the beam, and so on until all the branches are cut on the tree. If, due to the high crustle resistance of I.PI, the curved trunk does not pass between the open levers 10 and hits one of them, then as a result of the inertial force of the moving tree and the pulling force of the pulling mechanism, the receiving head will turn around the axis 8 at a certain angle . If the butt comes off the lever 10, then the body 9 under the action of the resultant R tension of the cable 15, the elastic force of the cable resulting from the difference in lengths of the descending and incoming branch of the cable, as well as the weight of the receiving head, will turn back to the stop 11 and further wood processing is similar to that described. If the butt does not come off the lever 10, the dragging will stop without breaking the levers 10, as the blow is softened by turning the receiving head. When the clamps-18 are opened, the butt will fall down, and when the housing 9, the beam 4 and the arms 10 are subsequently rotated, it rises to the working position and the processing continues.

Thus, due to the use of a roaring-mounted receiving head, the possibility of lever failure is eliminated and the possibility of
