Abstract

The utility model relates to the field of agricultural engineering, namely to the working bodies of cultivators designed to care for potato plants. The technical result of the utility model is to improve the quality of work. The technical result is achieved due to the fact that on the outer side of the toothed loosening strips, between their teeth, a screw winding of a flexible rod of circular cross section is welded. Rotary cultivator, containing a crankshaft with ends bent at an angle of 15°, a stand mounted with the possibility of circular rotation around the crankshaft in its middle part, followed by fixation by means of a bolt and locknut through the holes on the stand and a disc welded to the crankshaft, two conical rotary harrows with ring-connected toothed bars, connected by profile disks, with the possibility of free rotation, to the hubs, dressed with the possibility of rotation on the bent ends of the crankshaft, and on the outer side of the toothed loosening bars, between their teeth, a screw winding of a flexible rod of round section is welded.

Description

The utility model relates to the field of agricultural engineering, namely to the working bodies of cultivators designed to care for potato plants.

Known rotary cultivator [Author's certificate RU patent No. 2388199, IPC class. А01В 21/00, 2010], containing two conical rotary harrows attached to the hubs with the possibility of free rotation around a horizontal axis.

The disadvantages of the known rotary cultivator are the limited range of regulation of rotary harrows at the angle of inclination of the sidewall of the ridge and the high metal content of the structure.

The closest analogue to the claimed is a rotary cultivator [Author's certificate RU patent No. 177399, IPC class. А01В 21/00, 2021], containing a crank axle with ends bent at an angle of 15 °, a rack mounted with the possibility of circular rotation around the crank axle in its middle part, followed by fixation by means of a bolt and a lock nut through the holes on the rack and a disk welded to the crank axle , two conical rotary harrows with toothed bars connected by rings, attached with profile disks, with the possibility of free rotation, to hubs, dressed with the possibility of rotation on the bent ends of the crankshaft axle.

The disadvantages of this design is the shedding of loose soil from the slopes of the ridges in the aisle when exposed to toothed slats and inefficient combing of the roots of weeds. Each toothed bar moves along a curvilinear trajectory and penetrates into the soil of the slopes of the ridges to a depth that is variable in the direction of movement of the unit. In addition, flaws may occur between the zones processed by adjacent strips. These circumstances reduce the quality of loosening and combing out weeds. At the same time, loose soil crumbles from the slopes of the ridges along the inclined toothed bars in the aisle, which does not contribute to the preservation of the profile of the ridges.

The technical result of the utility model is to improve the quality of work.

The technical result is achieved due to the fact that on the outer side of the toothed loosening strips, between their teeth, a screw winding of a flexible rod of circular cross section is welded.

The specified set of essential features provides the inventive rotary ripper with new properties that are different from the prototype.

Thus, the claimed features of the utility model meet the criterion of "novelty".

In FIG. 1 shows a diagram of a rotary cultivator, rear view.

Rotary ripper containing a crankshaft with ends bent at an angle of 15° 5, 8, rack 9, installed with the possibility of circular rotation around the crankshaft in its middle part, followed by fixation by means of a bolt 11 and a locknut through the holes on the rack 9 and welded to the crankshaft disk 10, two conical rotary harrows with connected rings 3, 6 toothed bars 1, attached by profile disks 4, with the possibility of free rotation, to the hubs 7, dressed with the possibility of rotation on the bent ends 5, 8 of the crank axle, characterized in that on the outer On the side of the toothed loosening bars, between their teeth, a helical winding of a flexible round bar is welded.

Rotary cultivator works as follows.

In operation, rotary harrows, rolling over the surface of the ridge, loosen the soil, comb out the weeds, destroying the connection of the root neck of the weeds with the soil. At the same time, the screw winding 2 from a flexible round rod moves inside the slopes of the ridges at the same depth, eliminates flaws from the impact of the toothed bars 1, improves the quality of loosening the soil and combing out the weeds, and, similarly to the auger working body, moves the crumbled soil from the aisle to the slopes of the ridges , restoring their profile.

Thus, the claimed technical result is achieved.
