Insecticide feeding device of agricultural insecticide spraying machine

Abstract

The invention relates to the field of agricultural machines, and discloses an insecticide feeding device of an agricultural insecticide spraying machine. The insecticide feeding device comprises an insecticide box, an insecticide feeding pump, spraying rods and spraying heads. The insecticide feeding pump is connected with the insecticide box, the spraying rods are connected with the insecticide feeding pump, and the spraying rods comprise one main rod and a plurality of branch rods which are connected with the main rod in a rotatable mode. Each spraying head is mounted on the corresponding branch rod through a universal joint, each universal joint is provided with a control valve, and each control valve is used for controlling the corresponding universal joint to rotate. Each spraying head is provided with a flow distributing cover, and each flow distributing cover is provided with a plurality of insecticide spraying holes. According to the insecticide feeding device of the agricultural insecticide spraying machine, the spraying heads and the spraying rods which are at various angles and can be adjusted and the flow distributing covers are used, so that the insecticide spraying operation area is increased, and crop insecticide spraying is even. The insecticide feeding device is reasonable in structure, convenient to use, high in working efficiency and suitable for large-area field operation.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a drug delivery device for an agricultural sprayer. Background technique [0002] my country is a large agricultural country, and the frequent occurrence of diseases and insect pests has always been a problem that plagues the agricultural production of large fields. With the increasing development of agricultural mechanization and the continuous advancement of science and technology, people's technical requirements for agricultural machinery are also getting higher and higher. In agricultural production, spraying pesticides on crops to prevent pests is one of the important links. The sprayer used for spraying has become an indispensable tool for agricultural production. [0003] Due to the low efficiency of the traditional spraying method, the inability to adjust variables, and the poor accuracy, it is very difficult to control pests and diseases in large-scale operations. ...

AI Technical Summary

Problems solved by technology

[0003] Due to the low efficiency of the traditional spraying method, the inability to adjust variables, and the poor accuracy, it is very difficult to control pests and diseases in large-scale operations.

[0004] Existing pesticide spraying machines generally use fixed, single-flow nozzles, and the spraying coverage area is small. For large-scale field spraying operations, it is easy to cause uneven drug delivery to crops
