(54) MACHINE FOR STABLE CUTTING

one

The invention relates to a device for cutting stumps and can be used in the forest and wood processing industry.

Known machine for cutting edge

and stumps, including the frame, self-centering trays, splitting wedges and pressure plate drive hydraulic cylinder 1}.

Such a machine has a complex management and operation.

A device for splitting stumps is known, including the frame on which the cutter head is mounted, the pressure plate and the drive for moving it 2.

The disadvantage of this device lies in the fact that when working on it requires considerable time for laying a mon and keeping it until it is pressed by the plate to the knife head.

The purpose of the invention is to increase work efficiency.

This is achieved by the fact that in the lower part of the frame between the pressure plate and the knife head, a forked pallet is hinged, made in the form of cantilever spring-loaded beams, the free ends of which are directed towards the knife head.

Fig, 1 shows a machine for cutting stumps, side view; FIG. 2 is a section of the machine along A-A in FIG. 1; in fig. 3 - machine, top view.

The machine for cutting stumps contains frame 1, chassis 2, knife head 3, power cylinders 4, the rods of which are pivotally connected to a pressure plate 5, made in the form of a traverse with rollers, mixing along the guides of frame 1.

Between the pressure plate 5 and the blade head 3, a forked pallet 6 is hinged at the bottom of the frame 1, made in the form of several cantilever beams spring-loaded with respect to the frame 1 by springs 7. The machine for cutting stumps can be connected with a pull-on hook 8 not shown) equipped; hydraulic manipulator for feeding stumps.

The operation of the machine is carried out as follows.

Small and medium stumps are placed using the manipulator on the pallet 6. Under the action of the weight of the mon spring, the spring is 7 cm and the pallet 6 is lowered, turning relative to the hinge at an angle proportional to the weight and dimensions of the mon. At the same time, the central part of the mon is located against the knife head 3. With the working stroke of the power cylinders 4, the pressure plate 5, moving on the rollers along the guides of the frame 1, pulls the stump over the knife head 3, which cuts it into several parts.

When cutting large stumps that have long lateral roots, the pallet 6 under the action of the weight of the mon and the effort of the manipulator goes down to its lowest position, freeing up space for accommodating the lateral roots. If necessary, the largest stumps are supported by a manipulator.

After pressing through the knife head of the next day, the pallet 6 returns to its initial upper position under the action of the springs 7.

Since small and medium stumps constitute the overwhelming majority of them, but they are not cut by weight but by z

the pallet, significantly reduced the average cutting cycle of stumps increases the efficiency of the machine.
