Agricultural planting plant protection spraying operation device

Abstract

The invention relates to an agricultural planting plant protection spraying operation device. The device comprises a base frame, a spraying unit, a liquid guiding unit, a driven unit and a connectingblock, the spraying unit is arranged at the right end of the base frame, the liquid guiding unit is arranged at the upper end of the base frame, the driven unit is arranged at the lower end of the base frame, and the connecting block is arranged at the upper end of the base frame and located on the left side of the spraying unit. By the adoption of a spraying device dragged by a tractor, a large-range farmland can be sprayed at the same time, meanwhile, a large amount of pesticide can be carried at a time, and therefore the problems that the area of the farmland capable of being treated by a common device at a time is small, it is difficult to confirm where pesticide is exhausted, and the pesticide concentration of part of areas is too low are solved; and according to the agricultural planting plant protection spraying operation device, secondary spraying is conducted by receiving pesticide sprayed out under high pressure, so that the problem that the pesticide is excessively gatheredat a spraying point due to high-pressure pesticide spraying is solved, and the coverage area of single pesticide spraying is increased through secondary spraying.

Description

Technical field [0001] The invention belongs to the technical field of agricultural planting, and specifically is a spraying device for agricultural planting and plant protection. Background technique [0002] Plant cultivation industry: the agricultural production sector that cultivates various crops and obtains plant products. Plantation is one of the main components of agriculture. The social production sector that uses the life functions of plants to obtain grain, non-staple food, feed and industrial raw materials through artificial cultivation. In my country, the main components of agricultural production are rice and wheat. In the process of planting rice and wheat, pesticides are often sprayed. The mechanized planting process requires an automatic pesticide spraying device. [0003] For agricultural planting, pesticide spraying often has the following problems: 1. Existing pesticide spraying equipment usually uses plant protection drones for pesticide spraying. The area of ...

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
