Compound land preparation machine

Abstract

The invention discloses a compound land preparation machine. The machine comprises a walking tractor body, a front support, a rear support, tilling wheels and a seat, and is characterized in that a bearing table is arranged on the rear support, a lifting hydraulic cylinder is vertically fixed to the rear support, and the lifting hydraulic cylinder and the bearing table are parallellly arranged. An angle hydraulic cylinder is hinged to the bearing table, the middle of the cylinder body of the angle hydraulic cylinder is hinged to the end of a piston rod of the lifting hydraulic cylinder, the end of the piston rod of the angle hydraulic cylinder is fixedly connected to a protective hood, a first rotary tillage cutter set is installed at the two sides of the protective hood through a bearing pedestal, a rotary shaft at one end of the first rotary tillage cutter set penetrates through the protective hood, guiding shafts are symmetrically installed at the two sides of the protective hood, and are arranged in arc guiding cylinders, a second rotary tillage cutter set is arranged at the front end of a rotary tillage support, and a ridging cutter set is installed on a cross rod. The compound land preparation machine has the advantages that rotary tillage work and ridging work are conducted simultaneously, and the tillage time is thus shortened; meanwhile, the investment cost of equipment is reduced, and the automated degree is high.

Description

technical field [0001] The invention belongs to the technical field of agricultural land preparation machines, and in particular relates to a compound land preparation machine. Background technique [0002] With the continuous improvement of the level of agricultural science and technology, most of the farmland preparation work has realized mechanical operations, such as the use of machinery to complete operations such as rotary tillage of farmland soil, ditching and ridging, which greatly improved work efficiency. At present, among the plowing and land preparation equipment widely used in agricultural production, none of the equipment can complete the multi-operation procedures of loose plowing, crushing soil, and leveling at one time, and reach the ridge or sowing state after the operation. Most of the traditional farming methods of turning, harrowing, leveling, ridging or deep loosening, harrowing, and ridging are a waste of time and energy, and because of the need to wai...

AI Technical Summary

Problems solved by technology

Most of the traditional farming methods of turning, harrowing, leveling, ridging or deep loosening, harrowing, and ridging are a waste of time and energy, and because of the need to wait for the opportunity between each operation, precious time is wasted in vain. Because the whole process of land preparation took too long to complete, most of the water in the soil in the plow layer was completely lost. Although the plowed land was rectified, it lost precious water, which was counterproductive.

In addition, no matter what kind of land, the same rotary blade is used, which has great limitations, and it is impossible to select a suitable rotary blade for rotary farming on the land.
