Description

The utility model relates to agricultural engineering, in particular to implements for cultivating soil in two or more layers.

Known tool for processing salt licks [Copyright certificate SU patent No. 1142907, IPC class. А01В 79/02, А01В 35/02, 1989], including stands-knives, installed between them, made in the form of a torsoidal surface, plowshares with a lifting plate and side plates of a conoid shape fixed to the knives in front and bent at the rear.

The disadvantage of this tool for processing salt licks is the crumbling of the soil by the most energy-intensive method of compression and poor-quality processing of ordinary soils due to mixing of the fertile layer with the infertile one.

The closest analogue to the claimed is the working body of the soil cultivator [Copyright certificate SU patent No. 1724036, IPC class. А01В 35/22, А01В 13/00, 1992], containing knife stands with upper rectilinear and lower curved sections, the centers of curvature radii of which are located between the knife stands, installed between them in the lower part of the ploughshare, the blade and trailing edge of which are located horizontally , and the length of the trailing edge of the share is less than the length of the blade.

The disadvantage of this design is the insufficient crumbling of the soil and high energy consumption due to the compression of the soil by the stanchions-knives, installed with lateral planes at an angle to the direction of movement.

The technical result of the utility model is to improve the quality of deep loosening of the soil while reducing traction resistance.

The technical result is achieved due to the fact that the share is located at a certain angle to the horizon, the length of the rear edge of the share is equal to the length of its blade, the planes of the knife stands are parallel to the direction of movement, and above the share, between the knife stands, two freely rotating rotors with knives are horizontally installed separated by an additional share similar to the main lower share and extended forward and backward relative to it.

The specified set of essential features ensures the appearance of the inventive two-tier working body of the soil cultivator of new properties, different from the prototype.

Thus, the declared features of a utility model meet the “novelty” criterion.

FIG. 1 shows a diagram of a two-tier working body of a soil cultivator, front view, in Fig. 2 - the same, side view.

Two-tier working body of the soil cultivator, containing knife stands 2, 8 with upper rectilinear and lower curved sections, installed between them in the lower part of the share 1, and the share is located at a certain angle to the horizon, the length of the rear edge of the share is equal to the length of its blade, the plane of the stands - knives are parallel to the direction of movement, and above the ploughshare, between the knife racks, two freely rotating rotors with knives are horizontally installed, separated by an additional ploughshare, similar to the main lower one and extended forward and backward relative to it.

The work of the two-tier working body of the soil ripper is carried out as follows.

Before work, the soil cultivator is connected to the tractor using lugs 6, a connecting device located on a horizontal bar 7 welded to the knife racks 2,8 and in the upper part of the knife racks.

During operation, the additional ploughshare 4 cuts the top fertile soil layer, lifts it, partially crumbles it and feeds it to the rotor 5. Due to the difference in soil resistance in depth, the rotor 5 rotates and its knives 9 additionally crushes the fertile layer.

With a slight delay, the lower ploughshare 1 cuts the infertile soil layer, raises it, partially crumbles it and feeds it to the rotor 3.

Due to the difference in soil resistance in depth and the fact that in the upper position the knives of the rotor 3 are in the space under the furrow of the additional ploughshare 4, the rotor 5 rotates and with its knives 9 additionally crushes the infertile soil layer.

Due to the fact that the upper additional ploughshare is extended backward relative to the lower one, the soil of the lower infertile layer loosened by the rotor 3 is laid to the bottom of the furrow earlier, and then it descends from the ploughshare 4, feeding the loosened soil of the upper fertile layer by the rotor 5. At the same time, the elongated rear part of the additional ploughshare 4 prevents mixing of fertile and infertile soil layers, improving the quality of work.

The process of operation of the lower share requires less energy, since it takes place without the pressure of the upper fertile layer lifted by the upper additional share.

Due to the fact that the length of the trailing edge of the share is equal to the length of its blade, the side walls of the knife stands are parallel to the direction of movement and do not have an energy-consuming compressive effect on the soil.

All design features of the proposed two-tier working body of the soil cultivator in aggregate provide a better and less energy-consuming process of soil cultivation in two layers.
