Efficient deep ploughing machine tool with controllable ploughing depth

Abstract

The invention relates to the field of farming machines, in particular to an efficient deep ploughing machine tool with controllable ploughing depth. The efficient deep ploughing machine tool comprises a rack and a rotary tillage mechanism installed on the rack. Plough share sets with adjustable wedge-in angles are arranged on the portion, in front of the rotary tillage mechanism, of the rack in rows. The rack is connected to the tail of a tractor through an upper connecting rod and a lower connecting rod, a quadrilateral structure capable of moving in the vertical direction is formed by connecting parts of the rack and the tractor, and a jacking hydraulic cylinder is arranged in the middle of the quadrilateral structure. One end of the jacking hydraulic cylinder is connected to the position, close to an upper connecting rod connecting point, of the rack, and a cushioning device is arranged at the connecting end. The other end of the jacking hydraulic cylinder is connected to the tail of the tractor, and a stable triangular structure is formed by the jacking hydraulic cylinder and the upper connecting rod. By the adoption of the scheme, the efficient deep ploughing machine tool with controllable ploughing depth is simple in structure and convenient and rapid to operate, can effectively control the ploughing depth, and efficiently completes ploughing work at high quality.

Description

technical field [0001] The invention relates to the field of farming machinery, in particular to a high-efficiency deep-plowing machine capable of controlling the depth of plowing. Background technique [0002] With the rapid development of agricultural machinery, the process of agricultural mechanization is also advancing rapidly, especially in flat plain areas, the degree of mechanization of agricultural production is already very high. However, when all kinds of agricultural machinery enter the farmland to bring convenience to agricultural production, they are also constantly rolling the lower soil of the farmland, making it increasingly firm or even compacted, affecting the penetration of water and fertilizers, and causing the root development of crops. If it is not good, the yield will eventually be reduced, so it is necessary to carry out effective deep plowing operations on the farmland before sowing, and then there is a deep plowing machine. Existing deep plowing ma...

AI Technical Summary

Problems solved by technology

Existing deep plowing machinery, its main operation mode is similar to plow, its cultivated layer is deep, the active soil layer of farmland is thicker after operation, but there is the problem that the soil block of active soil layer is big, uneven, and is not convenient for sowing; at the same time Due to the fact that it is impossible to maintain a flat natural environment on the surface of the farmland, agricultural tractors and farming equipment fluctuate irregularly with the terrain, resulting in uneven thickness of the cultivated living soil layer, which affects the growth of local crops

[0003] In order to overcome these problems, some enterprises have achieved effective control of the depth of tillage by adding modern electrical control devices to agricultural machinery, but their structures are often fine and complex. The cost is relatively high, and farmers still need to obtain arable land suitable for crop growth and sowing through repeated operations more often, the farming efficiency is low, and the farming cost is high
