Small self-propelled high-clearance spraying machine

Abstract

The invention relates to a small self-propelled high-clearance spraying machine. The small self-propelled high-clearance spraying machine is mainly applied to plant protection operation of high stalkcrops such as cotton, corn and tobacco. The small self-propelled high-clearance spraying machine includes a rack, a walking device, an adjustable chassis, a boom spraying system, a flow control systemand a transmission system. The walking device includes a front wheel track adjusting device, a road wheel track adjusting device and a chassis height adjusting device; the boom spraying system includes a height adjusting rod, a sprayer system and a boom folding mechanism; according to the small self-propelled high-clearance spraying machine, the wheel track and ground clearance of the adjustablechassis can be adjusted, the wheel track adjusting range is 1-1.6 m, the ground clearance adjusting range is 0.6-1 m, therefore, requirements for planting row spacing of different crops and the heights of the crops in growth periods are met, and the universality of the small self-propelled high-clearance spraying machine in fields is improved; spraying heads are oppositely arranged up and down onthe vertical hanging rods at the two sides of each planting row, spraying is conducted in left and right directions, and therefore diseases and insect pests on the middle and lower portions of plantsof the high stalk crops can be effectively prevented and treated.

Description

technical field [0001] The invention relates to a small self-propelled high-ground-gap sprayer, in particular to a door-type spray system and an adjustable chassis for high-stalk crops, belonging to crop field management machinery. Background technique [0002] In the process of crop production, pests and diseases are an important cause of crop yield loss. At present, the main control measures for crop pests and diseases in my country are pesticide spraying. Therefore, the development of plant protection mechanization and the research of new plant protection technologies have become a top priority. [0003] At present, my country's crop spraying machinery is mainly traditional manual backpack type, which is not only low in efficiency but also poor in effect. Large and medium-sized spraying machines in developed countries have matured, and there are various styles such as traction, suspension and self-propelled. A large number of advanced technologies are adopted, which are ...

AI Technical Summary

Problems solved by technology

A large number of advanced technologies are adopted, which are not only safe, reliable, and easy to operate, but also realize low spray volume, fine spray, less pollution, high efficacy, and high prevention efficiency, which meets the requirements of environmental protection. High, and it is difficult to adapt to my country's crop planting model

In the middle and late stages of crop growth, the branches and leaves are luxuriant and layered, such as cotton, tobacco, corn and other crops, it is difficult for ordinary spraying machines to achieve good control effects

In addition, based on my country's national conditions, the crops are relatively scattered, the plots are small, and the row spacing of crops is not uniform, and it is difficult for existing machinery to work in the field.
