Mechanical spraying device for plant protection

Abstract

The invention discloses a mechanical spraying device for plant protection. The mechanical spraying device comprises two spray rods and spray heads, wherein the spray rods are parallel and are connected through multiple telescopic rods, two of the multiple telescopic rods are connected with a connecting rod hinged to a mechanical body for plant protection, a hydraulic cylinder hinged to the mechanical body for plant protection is hinged to the middle of the connecting rod, and the spray heads are uniformly arranged on the connecting rod. The mechanical spraying device is simple and novel in structure, the horizontal separation distance between every two spray rods can be adjusted through a telescopic rod, jet formation of the spray heads can be increased, jet angles of the spray heads can be adjusted through the hydraulic cylinder, the jet effect reached by the spray heads is good, and a pesticide spraying effect is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a spray device for plant protection machinery. Background technique [0002] When traditional remote-controlled agricultural plant protection machinery sprays pesticides, the spray equipment sprays a mist of liquid medicine downwards. The liquid medicine falls by its own weight and can only fall on the upward surface of the crops, especially when the branches and leaves of the crops are dense. The lower stalks generally have little chemical solution, the spraying is uneven, and the spraying effect is not ideal, which will cause some pests to be on the back of the leaves of the crops, and the pesticides will not have the effect of killing insects. [0003] At present, there is a foreign method to install an air curtain on the plant protection machine, and use the strong wind generated by the air curtain to blow the crops away so that the medicine can be evenly spray...

[0002] When traditional remote-controlled agricultural plant protection machinery sprays pesticides, the spray equipment sprays a mist of liquid medicine downwards. The liquid medicine falls by its own weight and can only fall on the upward surface of the crops, especially when the branches and leaves of the crops are dense. The lower stalks generally have little liquid medicine falling, the spraying is uneven, and the spraying effect is not ideal, which will cause some pests to be on the back of the leaves of the crops, and the pesticides will not have the effect of killing insects

[0003] At present, there is a foreign method to install an air curtain on the plant protection machine, and use the strong wind generated by the air curtain to blow the crops away so that the medicine can be evenly sprayed on the crops. However, this method is too expensive and not suitable for ordinary farmers
