Abstract

FIELD: agriculture; engineering.

SUBSTANCE: tool for packing of soil includes mounted one behind the other on a frame on the axes of rollers in the form of cylinders of the same diameter. On the lateral surfaces of the two cylinders in staggered holes are made. Rollers on axles mounted on one side of the same diameter sprocket connected chain. Asterisk installed so that the projection of the holes of the second roller on one and the same portion of the soil are the openings between the projections of the first roller. Hole diameter rollers does not exceed the maximum allowable size of the agronomic requirements of the lumps of soil.

EFFECT: such a constructive solution is provided to improve the quality and packing of soil crumbling lumps of soil.

Description

The invention relates to agricultural machinery, in particular to tools for rolling soil.

Known tool for rolling soil [Patent SU No. 1189360. Tool for rolling soil. Published 07.11.1985], including rollers mounted on the frame one after the other, made in the form of truncated cones, the larger diameter of the rear roller being 0.6 ... 0.8 larger than the diameter of the front roller, the larger base of each roller made concave, and the smaller - convex, the angle at the top of the rear roller is less than the angle at the top of the front roller by 1 ... 4 °.

The disadvantage of the tool is the insufficient quality of rolling the soil and crumbling lumps of soil.

Achievable technical result - improving the quality of soil rolling and crumbling lumps of soil.

The specified technical result is achieved in that the rollers are made in the form of cylinders of the same diameter. On the side surfaces of both cylinders, holes are made that are staggered. On the axes of the rollers on one side, sprockets of the same diameter are installed. The sprockets are connected by a chain so that when the rollers rotate, the projections of the holes in contact with the soil surface, the second roller on the same soil section are between the projections of the holes of the first roller. The diameter of the openings of the rollers does not exceed the maximum allowable agrotechnical requirements size of the soil lumps.

In FIG. 1 shows a general view of the tool for rolling soil, in FIG. 2 - the same, top view.

The tool for rolling the soil contains a frame 1, mounted on it one after another on the axes 2 of the hollow cylindrical rollers 3 and 4 of equal diameter.

On the side surfaces of both cylinders, holes 5 are made staggered. On the axes 2 of the rollers 3 and 4, on one side, sprockets 6 of the same diameter are mounted, connected by a chain 7, so that when the rollers 3 and 4 rotate, the projections of the holes 5 in contact with the soil surface, the roller 4 on the same soil section are between projections of the holes of the roller 3. The diameter of the holes 5 does not exceed the maximum allowable agrotechnical requirements the size of the lumps of soil. Also on the frame 1 is a towing device 8, which is pivotally connected to the frame 1 using the fingers 9.

The tool for rolling soil works as follows.

Using the trailing device 8, the implement for rolling soil is aggregated with a seeder or directly with a tractor. The rollers 3 and 4 are pre-installed in such a way that, when the rollers rotate, the projections of the holes in contact with the soil surface, the roller 4 on the same soil section are between the projections of the holes of the roller 3, and the sprockets 6 are connected in this position by chain 7. Then traffic. Rollers 3 and 4 begin to rotate, crushing the soil lumps and rolling the soil. During the rotation of rollers 3 and 4, part of the soil lumps crumbles due to the pressure on them of the continuous side surfaces of the rollers, and other parts of the side surfaces with holes 5 located on them intensively crush the soil lumps due to the impact of the edges of the holes on them 5. Some crumpled soil lumps through the holes 5 on the lateral surfaces of the cylinders of rollers 3 and 4 fall inside, where they are captured by the walls of the cylinders during its rotation, and then fall down, being crushed. The crushed lumps through holes 5 are poured onto the soil surface.

The part of the field surface treated with the solid surface of the roller 3 is then treated with the surface of the roller 4 with holes 5 made on it, and the part of the field surface treated with the surface of the roller 3 on which holes 5 are located, is then treated with the surface of the roller 4 located between the holes 5. This allows intensive crumbling of soil lumps over the entire area of the treated surface.

The presence of staggered holes on the side surfaces of the cylinders of the roller rollers, the diameter of which does not exceed the maximum size of the soil lumps allowed by the agrotechnical requirements, improves the quality of soil rolling and crumbling of soil lumps due to the double effect of the roller surfaces on the same section of the field, as well as ensure compliance of lumps remaining on the soil surface with agrotechnical requirements.

Claims (1)

A tool for rolling soil, including rollers mounted one after another on a frame on the axles, characterized in that the rollers are made in the form of cylinders of the same diameter, staggered holes are made on the lateral surfaces of both cylinders, the sprockets on the rollers’ axes are installed on the same side diameters connected by a chain, so that when the rollers rotate, the projections of the holes in contact with the soil surface, the second roller in the same section of soil are between the projections of the holes ervogo roller, wherein the diameter of the holes does not exceed the maximum allowable size of agronomic requirements of soil lumps.
