RU200464U1 - DISC WORKING BODY FOR SOIL PROTECTION FARMING - Google Patents

Abstract

The utility model belongs to the agricultural engineering industry, namely to disk working bodies and can be used for surface tillage on slopes with surface water erosion.

The technical result of the utility model is the retention of water runoff and a decrease in the intensity of soil erosion, both in the longitudinal and transverse directions with respect to the movement of the unit during soil cultivation on slopes with surface water erosion.

The technical result is achieved due to the fact that both parts are rigidly attached through the hubs to the opposite ends of the common axis, fixed by the middle part in the bearing unit of the rack at an angle to the direction of movement, each part of the working body has the shape of a half disk, and the projection of both parts, in side view , do not overlap.

A disk working body for soil-protecting agriculture, containing a cutting edge, consisting of two separate parts, each of which is soldered, and both parts are rigidly attached through hubs to opposite ends of a common axis, fixed by the middle part in the bearing assembly of the rack at an angle to the direction of movement, each part of the working body has the shape of a half of a disc, and the projections of both parts, in the side view, do not overlap.

Description

The utility model belongs to the agricultural engineering industry, namely to disk working bodies and can be used for surface tillage on slopes with surface water erosion.

Known analogue (Patent No. 95213, publ. 11.07.2011, bull. No. 13), containing a disk mounted on a frame with the possibility of rotation. Part of the arc of the cutting edge of the disc is additionally equipped with a flat support gusset with low pressure on the soil. The disadvantages of the analog are:

- poor-quality formation of bridges in the longitudinal direction, relative to the movement of the working body, on light soils due to the sinking of the support gusset into the soil;

- the impossibility of the formation of bridges that hold back water flow and soil erosion in the transverse direction relative to the movement of the working body;

- pulsating violation of the optimal operating mode of the tractor engine and excessive fuel consumption;

- accelerated wear of the device for ensuring the movement of the working body in the vertical plane and, accordingly, an increase in operating costs to ensure its operability.

The closest analogue to the claimed is the disc working body of the tillage machine [Copyright certificate RU patent No. 174882, IPC class. А01В 13/1, А01В 23/06, А01В 7/00, 2017], containing a cutting edge, and consisting of two separate parts, each of which has a soldering and a cut on the cutting edge, while a gap is formed between the parts of the disk working body. The disadvantages of this design are:

- poor-quality formation of bridges in the longitudinal direction, relative to the movement of the working body, on light soils. Due to the narrowness of the slots between the parts of the working body, the bulkheads are narrow and loose, which reduces their ability to retain water flow;

- the impossibility of the formation of bridges that delay the flow of water and erosion of the soil in the transverse direction relative to the movement of the working body due to the work of both parts on the same track.

The technical result of the utility model is the retention of water runoff and a decrease in the intensity of soil erosion, both in the longitudinal and transverse directions with respect to the movement of the unit during soil cultivation on slopes with surface water erosion.

The technical result is achieved due to the fact that both parts are rigidly attached through the hubs to the opposite ends of the common axis, fixed by the middle part in the bearing unit of the rack at an angle to the direction of movement, each part of the working body has the shape of a half disk, moreover, the projections of both parts, in the form from the side, do not overlap.

The specified set of essential features provides the emergence of a disk working body for soil conservation agriculture new properties, different from the prototype.

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

FIG. 1 shows a diagram of a working body for soil protection agriculture, explaining its device, front view, in Fig. 2 - the same, view A, without designation of the rack and bearing assembly, in Fig. 3 is a diagram of the placement of jumpers during soil cultivation by the claimed working body.

A disk working body for soil-protecting agriculture, containing a cutting edge, consisting of two separate parts 2, 4, each of which has a soldering 7, and both parts are rigidly attached through the hubs 1 to opposite ends of the common axis 6, fixed by the middle part in the bearing unit 5 of the rack 3 at an angle to the direction of movement, each part of the working member has the shape of a half of a disk, moreover, the projections of both parts, in the side view, do not overlap.

The work of the disk working body for soil conservation agriculture is carried out as follows. During the movement, each part 2 and 4 of the working bodies assembled into a battery for soil conservation agriculture alternately enters the soil, cultivating it and maintaining the continuous rotation of the common shaft. The part of the working body that is in the soil at an arbitrary moment of time, due to the installation of the axis of rotation at an angle to the direction of movement of the unit, cuts weeds and loosens the soil in section 9, Fig. 3, and the second part at this moment in time moves over the soil without interacting with it. In this case, the bridge 8 of FIG. 3, from soil of undisturbed structure. The dimensions, density and staggered arrangement of the formed bridges, Fig. 3, allow to retain water drains in both longitudinal and transverse directions.
