Description

The invention relates to agricultural machinery, namely, devices for undermining of roots and crops, their transportation and soil separation.

A digging device is known, which contains a passive plowshare and an active separator grill in the form of anti-phase oscillating strips that have a rectilinear shape 1.

However, the known device is prone to soil sticking in wet conditions and clogging with vegetable impurities.

The closest in technical essence and the achieved result to the invention is a digger of root and tuber crops, including sectional oscillating share with rods having periodically varying curvilinear shape, and a drive mechanism 2.

The drawbacks of the device are the poor quality of crust formation, the overhang of vegetative impurities and sticking to the soil.

The purpose of the invention is to improve the process of growing and separating the soil.

This is achieved in that the rods are made in the form of spirals.

FIG. 1 schematically shows a digger, side view; in fig. 2 - the same, top view; in fig. 3 is a diagram of the effect of the device on the formation, side view; in fig. 4 - the same, top view.

The digger comprises a frame 1, a sectional oscillating blade, each section of which consists of the cutting part 2 and is rigidly

connected with it two rods 3, having the form of an elongated cylindrical helix.

Sections of the plowshares are mounted on crankshafts of two consecutive crankshafts 4. The crankshafts of each shaft 4 are 180 ° out of phase. The shafts are driven by 4 chain gears through a system of sprockets 5.

Digger works as follows.

When the digger moves along the harvested rows, the tuber-bearing stratum is undermined by the cutting part of 2 sections of the plowshare, which moves along the cycloid. Next, the reservoir enters the separator surface of the digger formed from the spiral bars 3. When a pair of bars 3 of one section are moving up, the adjacent bars move down, resulting in a fracture along the sections of the ploughshare. Depending on the kinematic mode of operation of the plowshare, a particle of the layer A (Fig. 4) can move away from the separation surface. At the same time, it receives the impact of the downward branch of the helix and simultaneously shifts along the forming helix. As a result of complex movement, the formation is constantly subjected to fracture deformation and impact, which promotes better crushing of the formation and its separation.

The use of a digger allows to intensify the process of soil fortification and separation by changing the direction of the formation movement.
