Abstract

 A digging machine, including a frame with load-bearing bars, a device for hanging on a tractor, vertical racks and a working body, characterized in that a half-bucket is equipped in the rear of the working body, the walls of which converge at an angle of 8 °.

Description

The utility model relates to forestry and agricultural engineering, in particular, to machines for digging seedlings and seedlings with lumps of soil in nurseries and under the forest canopy for subsequent transplantation.

Known digging machine, including a frame with a hinged device for hanging on the rear linkage of the tractor, two buckets that perform the function of working bodies, and two hydraulic cylinders (RF patent No. 56112, IPC A01C 11/00, publ. 10.09.2006). However, this machine has an insufficient quality cut of the soil layer due to rupture, and not cutting of the roots, and their destruction. In addition, this machine is not intended for the preparation of landing pits.

Also known is a machine for digging up wood and shrub plants, including a frame with load-bearing bars, a device for hanging on a tractor, vertical stands and a staple-like working body with a lift (RF patent No. 2349078, IPC A01G 23/04, publ. March 20, 2009 - prototype) .

The disadvantage of this machine is the low quality of the digging of planting material due to damage to the root system in the process of digging. A lump of soil is not sufficiently densely formed.

The utility model solves the problem of increasing the efficiency and quality of digging large-sized planting material and preparing planting pits for subsequent plantings.

To solve this problem, in a digging machine containing a frame with load-bearing bars, a device for hanging on a tractor and vertical racks, according to a utility model, the working body is made in the form of two triangles directed by sharp angles towards the dug out seedling, a half-bucket is equipped in the back of the working body whose walls converge at an angle of 8 °.

This form of the working body gives a smoother, without jerking, entry into the soil, and a decrease in the loads acting on it due to an increase in the length of the cutting edge. Hydraulic drive loads are also reduced. The roots of plants are cut better and not broken, which improves the quality of the cut.

The base of the half-bucket is made with a variable radius, gradually decreasing towards its rear.

The walls of the half-bucket converge at an angle of 8 ° for a small compaction so that the soil lump is more rationally formed.

In Fig, 1 shows the proposed digging machine - side view; figure 2 is a section aa. Figure 3 shows the working body of the digging machine - side view; figure 4 is a top view of the working body.

The machine contains a frame with load-bearing bars 1 and a fastening device to the tractor 2, vertical racks 3 with a working body fixed to them in the form of two triangles 4, a half-bucket 5 in its rear part.

The vertical struts 3 and the working body 4 form a two-arm lever, which can be rotated by hydraulic cylinders 6.

Bearing bars 1 are made cantilevered with the ends lowered. They are equipped with hinges 7 for fastening the vertical struts and supports 8, placed under the hinges on the underside of the supporting bars.

The machine has a tubular stop 9 mounted on vertical posts 3.

The lower edge of the blade of the working body 4 in the initial I and final II positions is located at or below the supporting surface OO.

The half-bucket 5 is made with a variable radius R ₁ <R.

The digging machine works as follows.

The tractor with the attached machine moves in the direction V. The machine is in this case in a raised position, and the working body 4 is in the initial position I.

When the limiter 9 rests on the tree trunk, the operator stops the tractor, and using the hinged system, forcibly lowers the supports 8. The working body 4 is partially embedded in the soil until the bearings are in full contact with the soil.

Then the operator, using the handle of the distributor, sets the hitch control hydraulic cylinder to the neutral position and activates the hydraulic cylinders 6. With the oil supplied to the hydraulic cylinders 6, the working element 4 is turned to position II, cutting out the root system of the tree together with the lump of soil. A half-bucket 5 made with an alternating decreasing radius during rotation raises the soil lump, thereby facilitating its separation from the soil monolith and, to an insignificant degree, compacting it for better formation of the lump. When lifting a hitch, the soil lump completely breaks away from the soil surface. A cut seedling with a lump of soil is transported to the planting site or to a warehouse for storage.

The proposed machine can also be used to prepare planting pits for planting dug out seedlings by it. An educated planting hole completely repeats the contours of a soil coma with a seedling, thereby reducing labor costs and increasing the efficiency of work when planting plants or landscaping.
