Abstract

The invention relates to a horizontal disc type weeding claw device which comprises a spindle, a shell, a bottom disc, a cover plate and a weeding claw tooth. The shell is fixed on the cover plate; the weeding claw tooth is mounted on the bottom disc; the lower end of the spindle is connected with the bottom disc; the upper end of the spindle penetrates through the cover plate; the middle part of the spindle is sheathed with a joint coupler; the joint coupler is connected with the weeding claw tooth through a connecting bar; the joint coupler is provided with an adjusting plate; the adjusting plate is connected with the joint coupler; the adjusting plate is provided with a first adjusting nut and a second adjusting nut; the first adjusting nut and the second adjusting nut are respectively matched with a first adjusting screw and a second adjusting screw mounted on the shell and the cover plate; the joint coupler is controlled to drive the connecting bar to push or pull the weeding claw tooth connected with the joint coupler by rotating any adjusting screw so that all the weeding claws are simultaneously opened or folded so as to adjust the rotating radius of the weeding claw tooth and the distribution spaces between the tip ends of the weeding claw tooth to adapt to weed crops planted with different row spacing and line spacing. The horizontal disc type weeding claw device is skillfully designed, has a simple structure and is easy to realize automation and intellectualization.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a horizontal disc-type weeding claw device with an adjustable rotation radius. Background technique [0002] Cultivation and weeding is an important link in agricultural production. At present, weed control in agricultural production mainly relies on herbicides. Although herbicides have high weeding efficiency and quick results, they will bring about biological extinction, changes in weed communities, and weeds. Enhanced drug resistance and expanded drug resistance spectrum, environmental pollution and pesticide residues and other issues. In order to overcome the harm caused by chemical weeding, get rid of the heavy manual labor of manual weeding, and produce green food better, mechanical weeding methods have begun to receive more and more attention. The horizontal disc type weeding part is composed of a disc and claws on the outer edge of the disc. It is suitable for cult...
