Abstract

The utility model relates to agricultural engineering, namely to the working bodies of soil-cultivating machines. The technical result of the utility model is to improve the quality of work. The technical result is achieved due to the fact that vertical bushings are welded to the plane of the wings on the side of the longitudinal axis of symmetry of the tillage device with the same pitch, not protruding beyond the upper and lower edges of the wing, into which elastic fingers made of spring steel of a curved shape with a smooth bend are inserted with the possibility of rotation. in a longitudinal-vertical plane, ending on one horizontal line perpendicular to the direction of movement, spaced 7 cm from the ends of the wings in the top view, and 10 cm in the side view.

A universal soil-cultivating device, including an inclined holder with a horizontal plate heel welded at the bottom, a vertical axis screwed into the heel from below, two separate wings, mounted in front with a hole on the axis with the ability to rotate and connected behind each other by a mini-hydraulic cylinder installed with the ability to change the working width and remotely connected wireless an actuator with the hydraulic system of the unit, characterized in that vertical bushings are welded to the plane of the wings on the side of the longitudinal axis of symmetry of the tillage device with the same pitch, not protruding beyond the upper and lower edges of the wing, into which elastic fingers made of spring steel of a curved shape with the possibility of rotation are inserted a smooth bend in the longitudinal-vertical plane, ending on one horizontal line perpendicular to the direction of movement, spaced from the ends of the wings in the top view by 7 cm, and in the side view by 5 cm.

Description

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

A cultivator paw is known [RU patent No. 2714843, IPC class. A01B 35/20, 2020], containing a holder and two wings. The disadvantage of the known device is the low quality of tillage and high traction resistance.

The closest analogue to the claimed one is a combined unit with a universal tillage device [patent RU No. 206814, IPC class. A01B 35/20, 2021].

The disadvantage of the known device is the low quality of work. The design is not capable of combing cut weed roots to the surface, does not sift small erosion-hazardous soil fragments into the lower layer, and partially covers the mulch layer with soil.

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

The technical result is achieved due to the fact that vertical bushings are welded to the plane of the wings from the side of the longitudinal axis of symmetry of the tillage device with the same pitch, not protruding beyond the upper and lower edges of the wing, into which elastic fingers made of spring steel, curved, are inserted with the possibility of rotation. a smooth bend in the longitudinal-vertical plane, ending on one horizontal line perpendicular to the direction of movement, spaced 7 cm from the ends of the wings in the top view, and 10 cm in the side view.

This set of essential features ensures that the proposed universal soil-cultivating device has new properties 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 universal soil-cultivating device, a perspective view; Fig. 2 - view A of the wing in Fig.1.

A universal tillage device, including an inclined holder 4 with a horizontal plate heel 2 welded at the bottom, a vertical axis 1 screwed into the heel from below, two separate wings 3, 7, dressed in front with a hole on the axis 1 with the possibility of rotation, and connected behind each other by a mini-hydraulic cylinder 6 installed with the ability to change the working width and a remotely connected wireless actuator with the hydraulic system of the unit, characterized in that vertical bushings 8 are welded with the same pitch to the plane of the wings 3, 7 from the side of the longitudinal axis of symmetry of the tillage device, not protruding beyond the upper and lower edges of the wing, in the bushings are inserted with the possibility of rotation; elastic fingers 5 are made of spring steel of a curvilinear shape with a smooth bend in the longitudinal-vertical plane, ending on one horizontal and perpendicular to the direction of movement line, spaced from the ends of the wings in the top view by 7 cm, and in the side view - by 10 cm.

The universal tillage device works as follows.

Before starting work, the axle 1 is screwed into the heel 2 of the holder 4 from below. On axis 1, two separate straight wings 3, 7 with elastic fingers 5 are placed on top of each other through holes in their front parts and secured from below with a cotter pin 10.

When the tillage device moves in the soil, the wings 3, 7 cut off the soil layer and the roots of weeds with their cutting part 9. Next, the layer moves along the surface of the wings, the working body, where it crumbles under the influence of bending forces into fragments of various sizes. In this case, the connection between the roots of weeds and the soil is partially destroyed.

The resulting layer of soil moves onto elastic fingers 5. The curvilinear shape of fingers 5 contributes to the further destruction of the soil layer into smaller fragments. Due to the oscillations of the elastic fingers 5 in the longitudinal-vertical and horizontal planes, roots of weeds and large soil fragments are carried to the surface and small fragments are sifted between the fingers into a lower layer. A mulch layer is also brought to the surface, partially sprinkled with soil, gushing out when the holder moves.

Thus, there is a more effective destruction of weeds, preservation of the mulch layer on the surface, and sifting of small erosion-hazardous soil fragments into the lower layer, which characterizes an increase in the quality of work.
