UA127353U - SOIL LEVEL LEVEL - Google Patents

Abstract

The ground leveler contains a trailing device, frame, running wheels, alignment devices, spring mechanisms, support wheels, and additionally contains tooth harrows, which are equipped with teeth with damping devices and connecting chains.

Description

The useful model belongs to agricultural engineering and can be used in combined tillage units for pre-sowing tillage.

A well-known leveler, which includes a supporting frame to which a planning bucket is attached, running equipment, a photoreceiver of laser radiation and a bucket control hydraulic system

Prospectus of the Tom/peg company, 340, USA, 19821.

The disadvantage of this leveler is the leveling of small irregularities in the height and length of the field.

A.F. Zubkov / Bul. - 15.10.92. - Mo 38)|, which includes a frame, a ripper, a bucket, a furrow-roller and a device for supporting the cutting body of the furrower on the design profile.

The disadvantage of this planner is the inability to cut the soil in elevated places below the design mark during its first pass. Scrapers are used to eliminate elevated places characterized by small sections of soil, which work on leveling such irregularities with reduced productivity and insufficient accuracy of planning. In addition, the planer is unable to stably and qualitatively level the surface of the ground in various soil planning conditions, which requires increased energy costs.

The soil surface leveler is taken as a prototype, which consists of a trailing device, main and side frames, two rows of leveling devices, support and running wheels, rod rollers, curtains, spring mechanisms, hydraulic cylinders of side frames, hydraulic cylinders of running wheels and mechanisms for adjusting the support wheels (Pat. 121628 Ukraine, IPC (20106.01).

The disadvantages of this tool include the low quality of loosening in difficult and hard soil conditions in accordance with agrotechnical requirements and the impossibility of combing weeds and plant remains from the soil surface.

The useful model is based on the task of improving the leveler of the soil surface, in which, by installing toothed harrows equipped with teeth with damping devices,

It ensures high-quality leveling and loosening of the soil surface with simultaneous combing of weeds and plant residues in accordance with agrotechnical requirements. Damping devices on harrow teeth ensure stable, high-quality operation of the soil surface leveler in difficult and hard soil conditions.

The task is solved by the fact that tooth harrows, which are equipped with teeth with damping devices and connecting chains, are installed on the leveler of the soil surface, which consists of a trailing device, a frame, running wheels, leveling devices, spring mechanisms, support wheels.

The figure shows the proposed leveler of the soil surface.

The leveler of the soil surface consists of a trailing device 1, a frame 2, two rows of leveling devices 3, support 4 and running wheels 5, toothed harrows 6, which are equipped with teeth 7 with damping devices 8 and connecting chains 9, spring mechanisms 10, hydraulic cylinders of running wheels 11 and support wheel adjustment mechanisms 12.

The leveler of the soil surface works as follows. The work of the leveler begins with the adjustments of the working bodies. Adjustment of the working bodies is carried out on a firm, even platform in accordance with soil moisture. The support wheels 4 are adjusted to the appropriate height by the adjustment mechanism 12, then the leveling devices C are adjusted to the depth of soil cultivation using spring mechanisms 10.

With the help of a trailing device 1, the leveler of the soil surface is connected to the power tool (tractor). To transfer the machine from the transport position to the working position, the hydraulic cylinder 11 raises the running wheels 5, as a result of which the working bodies of the leveler are lowered to the ground surface. Toothed harrows are installed on the surface of the soil and the connecting chains 9 are tightened.

During the movement of the tillage unit along the field, the first row of leveling devices C sinks into the soil and levels high ridges, the second row smoothes the surface with the remains of the ridges, and finally, tooth harrows b, which are equipped with teeth 7 with damping devices 8, loosen the soil, finally level the field surface and combing weeds.

Thus, the application of the principle scheme of the proposed leveler of the soil surface makes it possible to perform high-quality leveling and loosening of the soil surface in difficult and hard soil conditions with simultaneous combing of weeds and plant residues 60 in accordance with agrotechnical requirements.
