Leveling machine with hydraulic lifting device

Abstract

The invention relates to a leveling machine with a hydraulic lifting device. The temper mill comprises a vehicle body, wheels, a soil-loosening plate, the hydraulic lifting device and a traction device. The soil-loosening plate comprises a frame and a ditching groove. The frame includes a first frame and a second frame. A straight support rack, an oblique support rack and a support plate are arranged on the first frame. One end of the ditching groove is arranged at the top end of the straight support rack, and the other end thereof is connected with the support plate. Each wheel comprises a steel ring, a plurality of protrusions of the same shape are arranged on the outer wall of the steel ring, a plurality of expansion pieces are arranged on the steel ring, and the width of the expansion pieces is larger than the width of the steel ring. The leveling machine has the advantages that the leveling machine is reasonable in structural design, the first vertical plate of the soil-loosening plate loosens soil, and the second vertical plate of the soil-loosening plate levels the loosened farmland; ditching can be performed during soil loosening, and work efficiency is increased; the frame is foldable, the horizontal area of the whole frame is reduced, and traveling on a small road can be achieved; the leveling machine is stable during moving and good in grip effect, and the wheels do not sink into the land too deeply.

Description

technical field [0001] The invention relates to a leveling machine with a hydraulic lifting device, which belongs to agricultural machinery. Background technique [0002] The leveling machine is mainly used for loosening soil in paddy fields. In agricultural production, cultivating the soil is an essential step. Large-scale machinery can be used to deep plow the soil and crush large clods of soil. This method of operation is suitable for loosening the soil before planting crops. At present, the structure of general tempering machine is relatively complicated, involving various operation steps, the operation is cumbersome, the machine is prone to failure, and it is not conducive to long-term use. Moreover, the area of ​​general loosening equipment is relatively large, and some small roads are not easy to pass, and are not easy to store. [0003] The general loosening equipment that has all can not carry out ditching, must carry out separately to farmland ditching, and is ve...

Problems solved by technology

However, the larger the wheel, the narrower it is relatively, and the traces sunk into the soil are deeper, and the grip effect is not good.

Moreover, the wheel sinking too deep is not conducive to smoothing the marks with the loosening board, which will cause uneven loosening
