A plant protection spraying device for agricultural planting

Abstract

The invention relates to an agricultural planting and plant protection spraying operation device, which comprises a base frame, a spraying unit, a liquid guiding unit, a driven unit and a connecting block. It is arranged at the lower end of the base frame, and the upper end of the base frame is provided with a connecting block, which is located on the left side of the spraying unit; the present invention can spray a wide range of farmland at the same time by using a spraying device pulled by a tractor, and can carry a large amount of pesticides at one time, thereby It solves the problem that the area of ​​farmland that can be treated by common devices at a single time is small and it is difficult to confirm where the pesticides are exhausted, which makes the concentration of pesticides in some areas too low; High-pressure spraying of pesticides can lead to excessive accumulation of pesticides at the injection point, and the coverage of a single pesticide spray is increased by secondary spraying.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, in particular to a plant protection spraying device for agricultural planting. Background technique [0002] Plant cultivation: the agricultural production sector that cultivates various crops and obtains plant products. Planting is one of the main components of agriculture. The social production sector that uses the life functions of plants to obtain food, non-staple food, feed and industrial raw materials through artificial cultivation. The most important components of agricultural production in my country are rice and wheat. In the process of planting rice and wheat, pesticides are often sprayed, and a device for automatically spraying pesticides is required in the process of mechanized planting. [0003] Pesticide spraying in agricultural planting often has the following problems: 1. The existing equipment for spraying pesticides usually uses plant protection drones for pestici...

AI Technical Summary

Problems solved by technology

[0003] Pesticide spraying in agricultural planting often has the following problems: 1. The existing equipment for spraying pesticides usually uses plant protection drones for pesticide spraying. The area of ​​farmland that can be processed by drones at a time is too small, and the speed of drones is too fast. , so it is difficult to confirm where the pesticide is exhausted, making the concentration of pesticide in some areas too low; 2. When spraying with nozzles, since the pesticide needs to be directed to multiple nozzles, it is necessary to divide the pesticide into multiple nozzles through high pressure Spray, so that the pesticide will be excessively concentrated at the spray point
