(54) MACHINE FOR CONTOUR CUTTING TREES AND CRUSHING CUT OFF BRANCHES

t

The invention relates to agricultural machinery, in particular, machines for contour pruning of trees with simultaneous chopping of cut branches.

A known machine for contour pruning of trees, comprising a frame with a cutting member fixed on it (disc saws) (1).

However, the cut branches are dropped between rows in a disorderly state, which makes it difficult to carry out subsequent technological operations to care for the garden.

A machine for trimming plant stems is also known, which contains a frame with stem lifters attached to it, a cutting organ, a trailer and a bunker. This machine provides the selection of thin stems with a weak branching branch structure 2.

Branched and thick branches of trees when entering the conveyors create congestion, which disrupts the work process.

The purpose of the invention is to expand the operational capabilities of the machine and

prevention of branched branching.

The goal is achieved by the fact that the machine is equipped with a beater-pick-up, a grinder, blocks of circular saws and conical augers attached to the belt with an orter, and the beater-pick-up is installed in the feed zone of large diameters of the conical augers, while the blocks of circular saws are fixed on a spring loaded lever suspension, and conical bows are set at an acute angle relative to

10 longitudinal axis of the machine.

FIG. 1 shows a machine for contour pruning of trees and shredding of cut branches, side view; FIG. 2 - the same, plan view; in fig. 3 - kinema1 $ 1 tichesky scheme of the machine, side view (nodes conventionally spaced along the length of the machine); / in FIG. 4 is the same, top view.

The machine for contour pruning trees and chopping the cut branches (Fig. 1 and 2) consists of a frame 1, fixed

The ED of the vehicle is 2 and two rotary beams 3 with rotating disc saws 4. One of the beams is made with a telescopic and movable link 5 which is horizontally hinged with a horizontal bar 6 with saws 7 to reduce the crown of trees. On the vehicle, the upper 8 and lower 9 sloping shields for cut branches are fixed. Longitudinal conveyors 10 are installed on the frame on the sides of the vehicle. Above each conveyor (Fig. 3 and 4) circular saw arms 12 are installed on the swing arm 11. Under the circular saw blocks on the frame, the guide 13 with longitudinal notches is pivotally installed, through which working edges of circular saws.

Over each conveyor in the rear part at an acute angle relative to the longitudinal axis of the machine are installed conical augers 14, which are located with their large diameters in the direction of the pick-up, 15 and connected to the shaft of the latter through an intermediate link 16. On the pick-up shaft, there are helix fingers 17. The feed rollers are mounted behind the beater-baler, the upper 18 and lower 19. The upper drum is mounted on the lever suspension 20 and is spring-loaded. A rotary chopper 21 with a pneumatic actuator 22 is located behind the rollers. The machine is driven from the tractor's power take-off shaft and contains a telescopic cardan shaft 23, from which movement is transmitted to the bevel gear 24. From the right, downstream gear output shaft 25, the movement is transmitted via V-belt transmission 26 on the shaft 27 of the drum grinder. From the left, along the assembly, shaft 28 of the bevel gearbox, the movement is transmitted by chain 29 to the counter-drive shaft 30, from which all other working bodies are driven: the pick-up, conveyors, upper and lower rollers, and circular saw blades. Under the receiving part of the chopper, the bottom 31 is fixed with edges curved in front and behind. The receiving hopper 32 is installed behind the chopper.

When the vehicle is moving between the rows, circular saws 4 and 7 (Fig. 1) of vertical 3 and horizontal 6 beams cut tree crowns in accordance with the specified dimensions.

The cut branches descend along shields 8 and 9 or fall directly onto the conveyors 10. The conveyors move the cut branches into the zone of spring-loaded blocks of circular saws 12. As the thickness of the layer of branches increases, the lever suspensions 11 turn overcoming the resistance of the springs and press the branches to the conveyors. The blocks of circular saws 12 (Figs. 3 and 4) cut the cutting edges Yio through the slots of the guide into separate parts, which are moved by screws 14 to the area of the beater picker 15 and further to the bottom 31. The beater picker fingers 17 pick up the previously cut the branches from the bottom 31 and direct them to the rollers 18 and 19, which compress these branches and feed them to the chopper 21. The chopped branches are thrown through the pneumatic actuator 22 into the hopper 32.

The use of the invention will expand the operational capabilities of the machine for contour pruning of trees and shredding of cut branches.
