Scratching smearing type weed removal device with targeted localization function

Abstract

The invention discloses a scratching smearing type weed removal device with a targeted localization function. The scratching smearing type weed removal device with the targeted localization function comprises a parallel operation part and a scratching smearing tool, wherein the parallel operation part comprises a servo motor, a driving arm, a driven arm, a telescopic rotating shaft, a connecting rotating shaft, a cross type universal joint and a load bearing tray; and the core parts of the scratching smearing tool are a scratching cutter head and a sponge smearing disc. According to the theory of plant physiology, a weed killer directly entering into weed bodies gives play to a relatively great pesticide effect, and therefore, the scratching smearing type weed removal device artificially scratches weeds and smears the weed killer on the cutting edges of the weeds so as to accelerate the absorption and conductive process of the weed killer in the weed bodies, improves the pesticide effect and reduces the dosage of the weed killer.

Description

technical field [0001] The invention belongs to the technical field of agricultural engineering, and relates to a weeding device, in particular to a scratching and smearing type weeding device with the function of targeting and positioning. Background technique [0002] At present, the commonly used weeding methods include manual weeding, mechanical weeding, weed quarantine, biological control and chemical weeding. Among them, for sudden weed damage, chemical weeding is the fastest. [0003] Precision pesticide application technology is a new trend in the development of weed control in the world today. It can target and fix pesticides according to the specificity of weeds' spatial distribution. However, the existing post-emergence chemical weeding devices mainly use simple covering spraying technology, which is not only highly destructive to the environment, but also easily causes crops to develop drug resistance. The most serious thing is that drug residues will endanger h...

Problems solved by technology

[0007] In order to solve the problems that the existing chemical weeding devices need to consume a large amount of chemicals and cause environmental pollution, etc., the present invention provides a weeding device, which can perform fixed-point treatment on the weeds after the machine vision technology obtains the spatial position of the weeds. Wound the weed cuticle, then apply a very small amount of the solution to the scratched surface
