Agricultural machine chassis of elevated structure

Abstract

The invention discloses an agricultural machine chassis of an elevated structure, and relates to agricultural machinery. The chassis of the structure can be used for hanging various agricultural machine tools and carrying out production operation special for high-plant crops. Vertical pipes (4) and a hydraulic steering mechanism are arranged in front of a chassis body (1), and elevated vertical legs (6) and a transmission mechanism are arranged in back of the chassis body (1). The hydraulic steering mechanism is composed of a front wheel connection frame (7), a vertical shaft (8), a steering support arm (9), a steering connection rod (10) and a steering hydraulic cylinder (11). The transmission mechanism comprises a chain (12) and a transmission gear (13). A machine head (2) can be fixed to rear wheels (5) at the lower ends of the elevated vertical legs (6) to rotate under the driving effect of the chain (12) and the transmission gear (13). The agricultural machine chassis has the advantages of being reasonable in design, small in size, simple in structure, low in manufacturing cost, high in spraying operation efficiency and the like.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to an agricultural machine chassis, through which a variety of agricultural machines can be articulated to carry out production operations for tall crops. Background technique [0002] With the continuous development of my country's agricultural mechanized production, pesticide spraying vehicles have begun to be used instead of manual spraying operations. At present, in the vast rural areas of our country, small four-wheel tractors carry medicine tanks on their backs for pesticide spraying. In the initial stage of crop planting, the crop plants are relatively short, and it is more convenient for small four-wheel tractors to work in the farmland. However, due to the low chassis of the small four-wheel vehicle, when the plants grow taller, the small four-wheel tractors are no longer suitable. Imported pesticide spraying vehicles are difficult to be accepted by farmers because they are expe...

AI Technical Summary

Problems solved by technology

Due to the high price of imported pesticide spraying vehicles, and its huge body is not suitable for field operations in various types of land in my country, it is difficult for farmers to accept them.

In recent years, many inventors have tried to use small locomotives to design sprayers that drag elevated structures, but due to imperfect structures and performance, these attempts have not been successfully introduced to the market

And because the pesticide spraying operation period is relatively short, the above-mentioned attempts all adopt an integral structure. After several times of spraying, the heads of these spraying machines will be idle and cannot be used, and the utilization rate is low. One reason why farmers are not optimistic

Furthermore, the spraying machine of the existing structure is only suitable for spraying operations, and cannot complete other agricultural productions such as loosening the soil, weeding, fertilizing, etc., and other agricultural machinery is not suitable for entering the field to work on tall crops.
