Description

The invention relates to agricultural engineering, in particular to soil cultivating rollers.

A well-known soil-cultivating roller [Khalansky V.M., Gorbachev I.V. Agreecultural machines. Agreecultural equipment. - M.: Kolos, 2004, p. 86-87], which is a hollow cylinder equipped with an axis and mounted on a frame with the possibility of rotation. To clean the hollow cylinder from adhering soil, the tillage roller is equipped with scrapers pressed to the surface of the hollow cylinder by springs.

The disadvantage of the tillage roller is the poor quality of soil compaction and crumbling of soil lumps.

The technical result is improved quality of soil compaction and crumbling of soil lumps.

The technical result is achieved by making the hollow cylinder perforated. On both sides, at an equal distance from the bases of the hollow cylinder, springs are installed on its inner surface with equal angular pitch along the circumference. Metal weights are installed at the outer end of the springs.

In fig. 1 shows a general view of the soil-cultivating roller; Fig. 2 - the same, section along A - A.

The tillage roller is made in the form of a perforated hollow cylinder 1, equipped with an axis 2. On both sides of the bases of the hollow cylinder 1, at an equal distance from them, springs 3 are installed on its inner surface with equal angular pitch along the circumference. Metal weighting agents 4 are installed at the outer end of the springs 3 .

The tillage roller operates as follows. Axle 2 of the perforated hollow cylinder 1 is connected to the coupling of the tillage unit. When the tillage roller moves, the perforated hollow cylinder 1 rolls over the soil surface, destroying soil lumps and compacting the soil. Due to the presence of perforation of the hollow cylinder 1, its contact area with soil lumps is reduced, which causes a corresponding increase in pressure on the lumps. As a result, the quality of their crumbling improves.

When rolling a perforated hollow cylinder 1 over the soil, springs 3 installed at an equal distance from the base on its inner surface with equal angular pitch around the circumference, together with metal weighting agents 4 installed at their outer end, due to shocks arising due to the unevenness of the field surface and the presence of lumps on it increased hardness, they begin to oscillate chaotically. These vibrations are accompanied by the emergence of additional multidirectional forces that create greater pressure on the soil surface and contribute to better destruction of soil lumps, providing an oscillating mode of soil compaction. The magnitude of these forces depends on the stiffness of the springs 3 and the mass of the metal weights 4.

Thus, making the hollow cylinder perforated, installing on both sides at an equal distance from the bases of the hollow cylinder on its inner surface with equal angular pitch along the circumference of the springs, as well as installing metal weighting agents at the outer end of the springs improves the quality of soil compaction and crumbling of soil lumps.
