(54) MACHINE FOR VYPODKI SEPARATION PITS

one

The invention relates to the field of agricultural engineering, in particular to a machine for crafts at planting forest and horticultural crops.

Pits when planting forest and horticultural crops are made with the help of auger diggers, mounted on tractors or self-propelled chassis.

Known wet mopers, including auger-type auger with a cylindrical casing, which is movably mounted on rails, and stop-stop, do not prepare the soil in accordance with the accepted agrotechnical conditions for laying forest, fruit and similar species.

The aim of the invention is to add a humus layer of soil to the bottom of the finished planting bed.

This goal is achieved by the fact that a spreader in the form of a cylinder and a cone attached to its outer surface is fixed conceptually and with a gap on the casing of the scooppel.

The drawing shows schematically the proposed machine.

A frame 1 is attached to the hydraulic lift of the tractor, on which a bevel gear 2 is mounted, which is connected by a drive shaft 3 to the tractor's power take-off shaft. On the driven shaft of the gearbox 2, a drill 4 is fixed, consisting of a screw 5, at the lower end of which there is a ploughshare 6. At the upper end of the drill 4 a ring reflector 7 of soil is mounted. The digger includes a spreader consisting of a cylinder 8 and a cone 9 connected by spokes 10. The cone 9 consists of an inner cylindrical wall 11 and an outer conical wall 12. The spreader is attached to the lower ends of the guides

rods 13, which pass through bushes 14, mounted on the frame of the machine. On one of the guide rods 13 under the sleeve 14 there is a frictionally fixed adjustable stop-limiter 15. The upper tails of the guide rods have stop pins 16. The digger is hung on the levers 17 of the tractor's hydraulic lift.

The drawing conventionally shows the dumps of the soil and its layers in the section: 18 - fertile topsoil, 19 - soil, 20 - btval of fertile soil layer, 21 - dump of soil, 22 - underlying soil sapling roots.

In the transport position under the action of its own weight, the spreader hangs on the rods 13, which burtal 16 abut against the ends of the sleeves 14. At the same time, the drill 4 does not protrude under the spreader. The device works as follows.

By the tractor's hydraulic ram, the machine is lowered onto the soil, and the dumper is the first to touch its surface.

The drive of the drill 4 is turned on and the oiiycKanne is continued: the driver with the levers of 17pdropod1, the tractor.

The plowshare 6 of the drill 4 cuts into the soil, which, falling on the peg 5, rises inside the cylinder 8 to its upper edge. Further, the soil, crossing over the upper edge of the pilind 8, will say i5 the annular volume formed by the cylinder 8 by the cylindrical wall of the cone 9.

After filling the ring volume, the soil passes over it and falls off around the conical wall 12. This is soil 19, which lies below the fertile soil 18. As the drill 4 is lowered into the soil, the guide rods 13 pass through the bushings 14 to the adjustable end support 15, the position :.: which, along paragraph 13, sets the final depth of us. After the excavation is completed, the machiniya is lifted by means of a hydraulic ram. At this time, the spreader continues to lie on the ground. due to the action of its own breech and due to the sliding of the guide rods 13 in the sleeves

14. Drill 4 support the dumper, and the soil left behind on the 5th screw of the screw will fall into the dump 21. After unbore 16 in the torn of the sleeves 14, the spreader will also rise simultaneously with the clamp 4.

Thus, the device digs up the landing mu, the node of which is poured by node-1 layun, 1 10, 22, at the edge we form a ring-shaped dump 20 fertile soil, conceptually dump 20 further from the edge, we separately formed a dump 21 of soil.

Subject invention

Claims (2)

1. A machine for digging up the landing m, including a screw auger with a cylindrical casing, movably mounted on the harness, and an end stop, characterized in that, with the aim of filling to the bottom finished planting we humus soil layer, on the casing, a spreader in the form of a cylinder and attached to its outer surface of the cone is concentrically and with a gap closed. 2. The machine according to claim 1, characterized in that the stop-limiter is fixed on one of the guides of the casing. 75 / i-v i rjTXj tr L, - I L / - r.i ten
