Description

The utility model relates to the field of agricultural engineering, in particular to the working bodies of rollers for soil treatment.

Known rollers for rolling soil, made in the form of disks with spurs (RU 2145158 C1, АВВ 29/04, 02/10/2002, DE 3229232, АВВ 29/04, 1984).

The disadvantages of the known rollers are insufficient alignment and grinding of clods of soil, a large metal consumption and sticky soil.

A spiral loopback roller is also known, including levers and a spiral having a wedge-shaped working surface, the turns of which are made with left and right windings (GB 2228851 A, A01B 29/04, 09/12/1990).

The disadvantages of this rink are the low reliability of the process, the possibility of jamming of plant residues and lumps of soil between the turns of the spiral, insufficient crumbling of lumps of soil.

The closest analogue of the utility model is a spiral loopback roller, including levers with bearing assemblies, as well as a drum pivotally mounted with bearings between the levers, and a roller from left and right-hand spirals having a wedge-shaped working surface (patent No. 2449520, А01В 29 / 04).

The main disadvantage of the described spiral loopback roller is its low degree of crumbling of soil lumps on its surface due to jamming of plant residues between the turns of the spiral and the uneven compaction of the soil in depth.

The problem to which the claimed utility model is directed is to increase the effectiveness of the impact on the soil over the entire width of the roller.

The technical result is an increase in the degree of crumbling of soil lumps over the entire width of the roller, as well as the creation of a mulching layer on the soil surface for the accumulation and preservation of capillary moisture in the arable layer.

The essence of the utility model is as follows.

A device comprising a spiral with turns mounted on the axles of the frame, teeth are installed on the turns of the working surface of the spiral, the fastenings of which are made in the form of screw clamps with lateral ellipsoidal anvils colliding with the lateral ellipsoid impactors of adjacent turns coaxially with them.

Common features with the prototype are:

spiral with turns

the spiral is mounted on the axles of the frame.

Distinctive features of the claimed decision are:

the teeth mounted on the turns of the working surface of the spiral,

tooth fastenings are made in the form of screw clamps with lateral ellipsoidal anvils.

The specified technical result in the implementation of the utility model is achieved by the fact that teeth are installed on the turns of the spiral working surface, which makes it possible to reliably engage the turns with soil without slipping and partially mixing the soil with crop residues to create a mulching layer. The tooth fastenings are made in the form of screw clamps with lateral ellipsoidal anvils, colliding with the lateral ellipsoid impactors of adjacent turns coaxially with them, which allows elastic vibrations when bending the turns at the moment they copy the surface relief of the soil and the impact effect between the anvils and impactors, which improves the interaction turns with soil.

The device is illustrated by drawings.

In FIG. 1 shows a general view of a spiral cable loop, front view.

In FIG. 2 shows a general view of a spiral loopback roller, side view.

The spiral loopback roller contains a spiral 1 with turns 2 mounted on the half shafts 3 of the frame 4 (Fig. 1). On the turns 2 of the working surface 5 (Fig. 2) of the spiral 1 (Fig. 1), teeth 6 are installed, the fastenings of which are made in the form of screw clamps 7 with lateral ellipsoidal anvils 8, colliding with the lateral ellipsoid drummers 9 of adjacent turns 2 coaxially attached to them.

The loopback roller spiral works as follows. When moving a loop-roller spiral with a spiral 1 and turns 2 mounted on the half shafts 3 of the frame 4 (Fig. 1) by the working surface 5 (Fig. 2) of the spiral 1 (Fig. 1) with installed teeth 6, rolling over the surface of the soil, its compaction and due to the engagement by the teeth of 6 turns 2 with the soil eliminates their slipping with partial mixing of the soil with crop residues to create a mulching layer. Due to the fastening of the teeth 6, which are made in the form of screw clamps 7 (Fig. 1) with lateral ellipsoidal anvils 8 colliding with coaxially fixed lateral ellipsoid impactors 9 (Fig. 2) of adjacent turns 2 (Fig. 1). It provides bending of the turns 2 at the moment of copying the relief of the soil surface and elastic vibrations with a shock effect between the anvils 8 and the impactors 9 (Fig. 1), which improves their interaction with the lumps of soil until they are completely destroyed.

Using the proposed tillage roller will increase the degree and quality of crumbling of lumps of soil along the entire width of the grip of the roller.
