Electric spray gun for bud inhibition

Abstract

The invention relates to an electric spray gun for bud inhibition. The electric spray gun comprises a shell; a diaphragm pump and a battery are arranged in the shell; the battery is electrically connected with a time delayer through a micro switch; the time delayer is electrically connected with the diaphragm pump; a water inlet of the diaphragm pump is connected with a water inlet pipe, and a water outlet of the diaphragm pump is connected with a spray nozzle through a pipeline. According to the electric spray gun for bud inhibition, provided by the invention, through integrating the diaphragm pump, the battery and the micro switch onto a gun body, the pipeline distance is shortened, and particularly, the distance between the diaphragm pump and the pipeline of the spray nozzle is shortened, therefore, the time delay of the whole spray gun is lower; with the cooperation of the micro switch with very accurate on-off, the accurate pesticide application rate control is conveniently realized. The arranged time delayer is a time delay disconnecting device; the accurate time delay disconnection is realized by utilizing a single chip microcomputer, so that after the micro switch is pressed down once, the accurate pesticide application rate is controlled, therefore, automatic control of accurate pesticide application is realized.

Description

technical field [0001] The invention relates to the field of planting auxiliary equipment, and relates to an electric bud suppression spray gun. Background technique [0002] Each leaf axil of the tobacco plant has 1-2 axillary buds, which are usually in a latent state under the influence of the dominance of the top of the tobacco plant before topping. After the topping of the tobacco plants, due to the artificial removal of the inhibitory effect of the top auxin on the axillary buds, these latent axillary buds will germinate rapidly from top to bottom and grow into branched tobacco, which will consume a lot of leaf nutrients and water, reducing the yield and quality of tobacco leaves. Therefore, timely bud suppression after topping is an effective measure to adjust the nutrition of tobacco plants and improve the quality traits of tobacco leaves in the late growth period of tobacco plants. There are generally two kinds of bud suppression methods, one is the traditional ar...

AI Technical Summary

Problems solved by technology

Most of the budding inhibitors currently recommended for tobacco are local systemic agents, which need to be sprayed on the axillary buds of tobacco leaves, which is difficult to achieve with existing sprayers

[0003] Chinese patent 200720089442.3 discloses a tobacco leaf germ-killing drench wiper, which can control the spraying range through the drench brush installed in front of the nozzle, and is suitable for local Suction agent, the existing problem is that because it is used in the existing sprayer, it is difficult to control the spraying amount, and the residue of the medicine is easy to exceed the standard, and the handle needs to be pressed continuously in the existing sprayer, and the height of the tobacco leaves is relatively high. It is easy to damage the tobacco leaves and affect the quality of the tobacco leaves
