A hydraulically controlled vibrating pressure roller

Abstract

The invention discloses a hydraulically-controlled vibrating type suppressing roller which aims at overcoming the defects that the pressure of a suppressing roller to a ridge table is unstable in the working process, the function is single and suppressing is not uniform. The hydraulically-controlled vibrating type suppressing roller comprises a fixed roller, a movable roller, a vibration generator, a support, a hydraulic pump, a hydraulic cylinder and a three-position four-way directional control valve, the pressure of the suppressing roller to the soil can be more uniform by the vibration generator, and further the density of the soil layer of the surface of the ridge table can be more uniform. The initial pressure of the suppressing roller to the ridge table can be more stable by hydraulic control, higher suppressing quality can be obtained, and the excellent growing environment of crops can be ensured. The soil blocks can be broken more easily by the aid of the protruding stripes on the outer surface of the movable roller, and the suppressing to the soil is more uniform.

Description

technical field [0001] The invention belongs to a hydraulically controlled vibrating pressure roller in the field of agricultural seeding in arid environment. Background technique [0002] The pressure roller plays an important role in the sowing process of crops. After the crops are sown, the soil is compacted and compacted, which can increase the density of the soil above the crop seeds, which is conducive to the retention of water in the soil and can make the crops better. Germination and emergence. Before there was no pressure roller on the planter, people needed to rely on their own body weight to step on it with their feet to keep the moisture in the soil, which may have an impact on the germination rate of crops due to the uneven force of people. At present, the pressing roller on the seeder is composed of a roller frame and several rollers installed on the roller frame, and the axis direction of the roller is perpendicular to the advancing direction of the traction ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the pressure roller that is generally used now can not guarantee the stability of the pressure on the surface of the ridge table during the suppression process, the pressure of the pressure roller on the surface of the ridge table is unstable during the suppression process, and the pressure of the pressure roller on the soil surface will be unstable. A wide range of changes occurs, resulting in problems such as uneven soil density after suppression and insufficient suppression pressure during the suppression process. A hydraulically controlled vibrating pressure roller is designed. Under the vibration of the vibration generator, it can increase The pressure of the pressing roller on the soil makes the density of the soil more uniform after pressing, so as to reduce the loss of water in the soil. The striped protrusions on the surface of the moving roller can reduce the slipping phenomenon during the pressing process, and can also reduce the work wear of the moving roller during the process, prolonging the service life
