Background

China has attracted attention for agricultural development, and great breakthrough is made on a plurality of agricultural production projects. The method has a breakthrough around the mechanization of nine major crops such as wheat, rice, corn, potato, soybean, rape, peanut, cotton, sugarcane and the like. However, in the process of agricultural mechanization development in China, a plurality of problems are exposed, such as landforms of hills, mountains and the like, large-scale mechanized agricultural production cannot be carried out, and some cultivations are carried out by manpower, so that rapid development of agriculture is greatly restricted. The main reasons are as follows: hills and mountains are numerous, the terrain is complex, the operation scale of agricultural production is small, large and medium-sized agricultural implements are difficult to operate on the ground in the growth state of crops, and the utilization rate of small agricultural implements is low during operation; the different topography in hilly mountain area, the climate difference is great, and the crop kind is more, and the high-yield high-quality high-efficient agricultural development has higher and higher requirements to agricultural machinery and agronomy integration, and same kind of crop, under different growth conditions, the agronomy also probably has great difference, and required agricultural implement type is many.

In a plurality of agricultural implements, the difference of structure and power requirements is obvious, the degree of universalization of parts is low, great difficulty is brought to research, development, manufacturing and maintenance of the agricultural implements, the research and development period is long, the mechanization process of the mountain agriculture is slow, and the development speed of the agriculture is influenced. The research and development of universal parts of agricultural implements are accelerated, the design and manufacturing period can be shortened, and the method has important significance for the development of agricultural mechanization.

The transmission mechanisms of agricultural implements at home and abroad are mostly arranged in a mechanical transmission mode, and the hitching machine frames are different. The problems of transmission and hanging between the prior agricultural implement and the tractor are shown in the following aspects:

1. most of the existing agricultural implements are hung on a tractor in a three-point suspension mode, power is output from the rear power of the tractor, and under the mechanical transmission condition, due to space limitation, the layout of a transmission structure is difficult, and the product development and production difficulty is high;

2. for the agricultural implement adopting the front suspension, under the mechanical transmission condition, most of transmission needs to be arranged below the tractor, so that the ground clearance of the tractor is reduced, and the passing performance is influenced;

3. the rear power output rotating speed of the tractor is only 1-2, because of the difference of the power rotating speed requirements of different agricultural implements, in the traditional mechanical transmission mode, each agricultural implement must be equipped with a corresponding transmission device and a corresponding speed reducer, and a corresponding suspension frame is designed and manufactured according to the requirement of the arrangement direction, the forms of the frames of the agricultural implements are different and can not be used universally, so that the cost of the implements is high.
