RU221285U1 - WORKING BODY FOR SURFACE TILLAGE OF SOIL - Google Patents

Abstract

The utility model relates to agricultural engineering, in particular to the working bodies of soil-cultivating machines.

The technical result of the utility model is a reduction in traction resistance while increasing the quality of work.

The technical result is achieved due to the fact that the furrow bottom seal consists of a roller located under the bar, the axis of which is installed horizontally and perpendicular to the direction of movement in sliding bearings on racks welded to the bar, and the end of the bar is bent down, forming a gap of 5 mm with the surface of the roller .

A working body for surface tillage of the soil, including a pointed paw, a stand, a triangular-shaped bar with holes attached to the stand with a bolted connection and a stop with a clamp, a furrow bottom compactor, wherein the furrow bottom compactor consists of a roller located under the bar, the axis of which is installed horizontally and perpendicularly to the direction of movement in the sliding bearings on the racks welded to the bar, and the end of the bar is bent down, forming a gap of 5 mm with the surface of the skating rink.

Description

The utility model relates to agricultural engineering, in particular to the working bodies of soil-cultivating machines.

A working body for surface tillage of soil is known [Copyright certificate RU patent No. 212647, IPC class. A01D 35/26, 2022], consisting of a lancet paw, a stand, additionally behind the lancet paw there is a rigidly installed bar with knuckles, attached to the stand using slats with a bracket in the upper part and a bolted connection in the lower part, while the front part of the bar has a one-sided bottom sharpening with an angle δ<90°-φ, and the front part of the tips has a double-sided sharpening with an angle (β<90°-φ, where φ is the angle of friction of the soil on the material of the elements of the working body for surface tillage, and the front part of the tips is shifted back relative to the front of the bar.

The disadvantage of the known working body is the shedding of the dry top layer of soil between the pointed paw and the bar with tips, which leads to mixing of the soil and a decrease in its moisture in the compaction zone.

The closest analogue to the claimed one, chosen as a prototype, is a working body for surface tillage [Copyright certificate RU patent No. 217453, IPC class. A01B 35/00, 2023], including a pointed paw, a stand, a triangular-shaped bar with holes and caps, attached to the stand with a bolted connection and a stop with a clamp, a furrow bottom seal.

The disadvantage of the prototype is high traction resistance and insufficient work quality. When compacting the bottom of the furrow with pads, sliding friction forces of the soil against the material of the pads arise, increasing traction resistance. The tips unevenly compact the bottom of the furrow, which does not ensure a uniform flow of moisture to all seeds sown later, and therefore reduces the quality of work.

The technical result of the utility model is a reduction in traction resistance while increasing the quality of work.

The technical result is achieved due to the fact that the furrow bottom seal consists of a roller located under the bar, the axis of which is installed horizontally and perpendicular to the direction of movement in sliding bearings on racks welded to the bar, and the end of the bar is bent down, forming a gap of 5 mm with the surface of the roller .

This set of essential features ensures the appearance of new properties in the working body for surface tillage that differ from the prototype.

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

In fig. 1 shows a diagram of a working body for surface tillage, top view, Fig. 2 - side view of the plank with the roller, Fig. 3 - top view of the bar.

A working body for surface tillage of the soil, including a pointed paw 1, a stand 2, a triangular strip 5 with holes 8, 9, attached to the stand 2 with a bolt connection 4 and a stop 3 with a clamp 12, a furrow bottom sealer, wherein the furrow bottom sealer consists of a under the bar 5 of the roller 6, the axis 7 of which is installed horizontally and perpendicular to the direction of movement in the sliding bearings on the racks 11, welded to the bar 5, and the end 10 of the bar 5 is bent down, forming a gap of 5 mm with the surface of the roller 6.

The technological process of the working body for surface tillage is carried out as follows.

When moving in the soil, the working body for surface tillage of the soil, with the working edges of the pointed paw 1, fig. 1, trims weeds and loosens the soil.

The top layer of soil and trimmed weeds move along the pointed paw 1 of the working body for surface tillage, then, passing along the upper part of the bar 5, FIG. 2, laid in an even layer on the surface of the field. Due to the rigid fastening to the stand 2 with a bolt connection 4 and a stop 3 with a clamp 12, the bar 5 with the roller 6 is held in the soil cultivation plane, copying the relief. The bottom layer of soil in the treated area is evenly compacted across the entire width by roller 6, fig. 3, which allows moisture to be drawn from deeper layers evenly to all seeds sown later and increases the uniformity of their germination time.

To prevent shedding of the dry top layer of soil between the pointed paw 1 and the bar 5, the bar has a solid surface with a rectangular hole 8, Fig. 4, for installing stand 2. This eliminates the mixing of dry and wet layers of soil in the compaction zone. The traction resistance of the working body is reduced due to the lower rolling resistance of the roller 6, compared to the resistance of the frictional forces of soil sliding on the material of the tips of the prototype.

Thus, the stated technical result is achieved.
