Flow guide plate for pesticide applying machine special for cotton

Abstract

The invention provides a flow guide plate for a pesticide applying machine special for cotton. The flow guide plate comprises a flow guide plate body, wherein the flow guide plate body comprises an arc-shaped partition, an S-shaped partition and a plurality of fins; the fins are vertically connected with the arc-shaped partition and the S-shaped partition; the fins, the arc-shaped partition and the S-shaped partition are connected to form a plurality of channels. The flow guide plate for the pesticide applying machine special for the cotton, provided by the invention, can change the direction of high-pressure airflow, and the high-pressure airflow is blown out of a wind barrel, so that the wind speed in the effective pesticide applying area range is basically uniform in the fogdrop dispersing process and the fogdrops can penetrate through dense branches and leaves of the cotton well.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a deflector for a special spraying machine for cotton that improves the spraying effect. Background technique [0002] Cotton is an important economic crop in my country, and for the application of cotton fields, domestically, a pure pressure atomizing sprayer is usually used to spray pesticides from the top of the cotton canopy, and the liquid medicine cannot pass through the dense cotton canopy, so , the amount of liquid medicine deposited in the middle and lower parts of the canopy is very small, and the effect of pest control is not good. [0003] In order to solve the above problems, a kind of spraying machine that sends out the medicine mist by wind is gradually developed in China. [0004] Disclosed as Chinese patent CN104012508A is a kind of high-efficiency sprayer suitable for cotton fields, including: support, fan, fan power system, medicine box, medicine...

AI Technical Summary

Problems solved by technology

However, there is a defect in the technical solutions disclosed in the above two Chinese patents: through investigation, the densest area of ​​cotton branches and leaves is distributed at a height of 250mm-700mm from the ground, and within this range, how much cotton leaves are distributed? Therefore, it is necessary to make appropriate adjustments to the demand for the liquid medicine to distribute the medicine reasonably, and improve the efficiency of the medicine application on the basis of saving costs. However, the existing air-driven sprayers all use fan-shaped nozzles, so , the wind and mist channel is narrow, especially when the leaves block the channel, it will inevitably affect the uniform spraying effect of the wind and fog, thus affecting the spraying effect
