Abstract

The utility model relates to agricultural engineering. The working body of the tillage roller is a disk made in the form of a truncated cone and mounted on the shaft vertically relative to its base, and on the smaller base of each disk there is a hub with a hole for the shaft and a rim having a polyhedral outer edge, the edges of which have recesses, due to which Pointed ribs are formed on the outer edge. The recesses on the edges of the outer edge can be made in the form of an angle, or a semicircle, or a semi-oval. The recesses on the edges of the outer edge can be made transversely, either along, or at an angle to the edge of the outer edge. On the rim of the disk can be additionally made stiffeners. Holes may be made on the rim of the disc. Disks on a shaft can be installed to each other with the same or opposite bases. The technical result is an increase in the quality of soil cultivation, due to the intensification of the process of crushing and destruction of blocks, lumps and soil crusts.

Description

The technical field to which the utility model relates.

The utility model relates to agricultural engineering, namely to the soil cultivating working bodies of field rollers, and can be used to level and compact the soil surface, crushing and destroying blocks, lumps and crusts.

State of the art

Known working body for tillage (RF patent for the invention No. 2402895, class IPC A01B29 / 04, publ. 10.11.2010), which is made in the form located at an angle to the direction of movement of the ring. The ring has the shape of a truncated cone and is connected via knitting needles to a hub or axle. The larger base of the ring is directed forward in the direction of travel and has a working edge 6–12 mm thick. The surface of the working edge is inclined outward from the plane of the larger base. The angle of inclination of the surface of the working edge is more than 20 °. Such a constructive implementation will improve the efficiency of weed control mainly by tearing and the quality of soil cultivation by increasing the depth of the ring.

The disadvantage of the working bodies of this skating rink is the relatively low quality of soil cultivation, namely, insufficient crushing of blocks, lumps and crusts, which is due to the ring shape of the working body of the tillage device.

Utility Model Disclosure

The problem to which the claimed utility model is directed is to create a device that can be used to crush dry lumps even on the hardest soils, to roll winter crops in order to increase tillering, as well as to press plants into the soil and prevent them from bulging out.

The technical result achieved using the proposed utility model is to improve the quality of soil cultivation due to the intensification of the crushing and destruction of blocks, lumps and soil crusts.

The specified technical result is achieved in that the working body of the tillage roller is a disk made in the form of a truncated cone and mounted vertically on the shaft relative to its base, with a hub with a hole for the shaft and a rim having a many-sided outer edge located on the smaller base of each disk which have recesses, due to which pointed edges are formed on the outer edge.

The recesses on the edges of the outer edge can be made in the form of an angle, or a semicircle, or a semi-oval.

The recesses on the edges of the outer edge can be made transversely, either along, or at an angle to the edge of the outer edge.

On the rim of the disk can be additionally made stiffeners.

Holes may be made on the rim of the disc.

Disks on a shaft can be installed to each other with the same or opposite bases.

The following notation is used in the figures: 1 - hub with a hole for the shaft 8, 2 - disk rim, 3 - multifaceted outer edge of the disk, 4 - recesses on the edges of the outer edge, 5 - pointed ribs on the outer edge 3, 6 - stiffeners of the rim 2 7 - holes on the rim 2, 8 - the shaft of the disk battery, 9 - disks - the working bodies of the roller.

Utility Model Implementation

The working body of the tillage roller is a disk 9, made in the form of a truncated cone and mounted on the shaft vertically relative to its base, and on the smaller base of each disk there is a hub 1 with an opening for the shaft 6 and a rim 2 having a polyhedral outer edge 3. The edges of the outer edge 3 have recesses 4, due to which pointed ribs 5 are formed on it.

The recesses 4 on the edges of the outer edge can be made in the form of an angle, or a semicircle, or a semi-oval. The recesses 4 on the edges of the outer edge can be made transversely, either along, or at an angle to the edge of the outer edge 3.

Disks 9 are cast, made of cast iron, have a large weight, which ensures guaranteed powerful impact of the rink disks on the soil with high-quality crushing of soil lumps.

To strengthen the design of the disk on the rim 2 can be made of stiffening ribs 6 (see Fig. 2), which is especially true for large disks used for processing heavy soils.

To facilitate the design of the disk, holes can be made on the rim 2 (see Fig. 3), which also provides an additional opportunity for the cultivated soil to pass.

Disks 9 on the shaft can be mounted to each other with the same (smaller or larger) bases, that is, the smaller base of one disk to the smaller base of the other and the larger base of one disk to the larger base of the other. Disks 9 can also be mounted to each other with opposite bases, that is, a smaller base of one disk to a larger base of another (see Fig. 4), and vice versa (not shown in Fig.).

The working body of the tillage roller is used as follows.

When the tillage roller moves, the disk 9 is rolled onto blocks of soil, while the constructive (toothed) solution of the edge 3 of the disk having recesses 4 and pointed ribs 5 provides intensive crumbling and leveling of the soil. In the process of movement of the roller on the multifaceted outer edge 3 of the disk 9 due to the inclination of its surface, a compacted soil wedge is formed. Loosening of the soil layer and the effect on weeds is carried out by a compacted soil wedge. At the same time, the soil reaction, pushing the discs, is reduced, which contributes to the penetration of plants into the soil.

Due to the constructive solution of the disk 9 in the form of a truncated cone and the use of several disks 9 as a part of the working body, the working body of the roller ensures high-quality soil rolling.

The recesses 4 additionally provide rolling of the adhered soil and prevent the adherence of the soil to the disks 9.

Thus, the claimed design of the working bodies - the rink disks, provides a very aggressive effect on the soil and plants, which allows this type of disc to be used, for example, for pre-treatment of stubble in severe drought, or to crush dry lumps even on the hardest soils, or use these rollers for rolling winter crops in order to increase tillering, as well as pressing plants into the soil and preventing them from bulging out.

A comparative analysis of the claimed utility model showed that the set of essential features of the claimed device is not known from the prior art and therefore corresponds to the patentability condition “Novelty”.

The above information confirms the possibility of using the claimed device in agricultural engineering, which can be used to level and compact the soil surface, crushing and destroying blocks, lumps and crusts and therefore meets the patentability condition “Industrial Applicability”.
