Air-conveying spray pesticide spraying device

Abstract

The invention provides an air-conveying spray pesticide spraying device, and belongs to the technical field of agriculture. The problem that part of pesticide sprayed by an existing air-conveying spray pesticide spraying device is condensed into water drops and naturally settles is solved. The air-conveying spray pesticide spraying device comprises a shell assembly, a fan and a spray head, wherein an air passing channel is formed in the shell assembly, an air inlet of the air passing channel is located in one end wall of the shell assembly, and an air outlet of the air passing channel is located in the side wall of the shell assembly; the air passing channel comprises an air inlet section and an air outlet section, the fan is located in the air inlet section, the spray head is located in the air outlet section, the air passing channel further comprises a drainage section, the air inlet section and the air outlet section communicate through the drainage section, a rectification structure is arranged in the drainage section, and the rectification structure is fixedly connected with the shell assembly. The air passing channel of the air-conveying spray pesticide spraying device is additionally provided with the drainage section, and the rectification structure is additionally arranged in the drainage section; and the circumferential air pressure uniformity in the air outlet section is improved, and the possibility that water mist sprayed from the spray head is condensed into water drops is reduced, that is, more water mist is taken away by airflow.

Description

Technical field [0001] The present invention belongs to the field of agricultural technology, and involves a pharmaceutical device, particularly a wind-moving spray drug. Background technique [0002] Pharmaceutical refers to people who spray pesticides during treatment of crops, and air-moving spray drugs are equipment that spray pesticides. About the related literature of spraying pesticide equipment, such as a self-propelled drug (application number 201922090839.x), including crawler, internal combustion engine, medicine box, fan, pill, oil pump, fuel tank and other components. The upper portion of the fan support frame is provided, and the liquid pump outputs the spray device for the fan; the structure can achieve spraying pesticides, there are some shortcomings: 1. The length of the liquid sprayed out is relatively short, usually only suitable for A low shrub spraying pesticide, not suitable for tall trees spraying pesticides. 2. Some pesticides discharged from the spraying ...

AI Technical Summary

Problems solved by technology

A fan is arranged on the upper part of the fan support frame, and the drug pump outputs the liquid medicine to the spraying device of the fan; although this structure can realize the spraying of pesticides, there are some shortcomings: 1. The length of the sprayed liquid medicine is relatively short, usually only suitable for spraying pesticides. Spraying pesticides on low shrubs is not suitable for spraying pesticides on tall trees

2. Part of the pesticide sprayed by the spraying device condenses into water droplets, which drop on the ground under the action of gravity, which not only wastes agriculture, but also affects the environment

3. The medicine box and the fan are respectively arranged at the two ends of the longitudinal beam, which not only has the problem of long liquid transportation distance and complicated pipeline arrangement, but also has the problem that the medicine liquid will sway in the medicine box when the vehicle is running, and as the liquid medicine gradually If it is used, the center of gravity of the vehicle will shift, which is not conducive to walking, especially not conducive to climbing
