Walking type weeding machine

Abstract

The invention relates to a walking type weeding machine. According to the technical scheme, a horizontal work arm stretching outwards is arranged on the lower portion of a vertical supporting rod, a weeding mechanism is arranged at the front end of the work arm, and the weeding mechanism comprises a guide sleeve, a telescopic column, a motor, a weeding disc protection cover, a weeding cutter discand a weeding cutter; the guide sleeve is fixed to the front end of the work arm, the upper end of the telescopic column is coaxially connected with a height adjusting screw rod, and a limiting nut isscrewed on the height adjusting screw rod, and a pressure spring is arranged between the limiting nut and the guide sleeve; the weeding disc protection cover is fixed to the lower end of the telescopic column, the motor is fixed to the side wall of the lower portion of the telescopic column, and a rotary shaft of the motor is vertically arranged downwards, and an extending shaft coaxially connected with the rotary shaft of the motor is mounted on the rotary shaft of the motor; the lower end of the extending shaft stretches into the position below the weeding disc protection cover, and a fixedly connected weeding cutter disc is mounted at the stretching-in end of the extending shaft. According to the walking type weeding machine, the labor cost is greatly reduced, the weeding cutter rotates below the ground surface, weeds are removed with along with roots, and efficient weeding is carried out in the advancing process.

Description

technical field [0001] The invention relates to a walking weeder. Background technique [0002] Herbicides have certain side effects and will cause a lot of harm during use. Generally speaking, herbicides have certain effects on plants, pathogens, soil microorganisms and the environment. And it will not only cause environmental pollution, but also indirectly cause harm to the human body. [0003] Land pollution: After spraying herbicides on farmland, the herbicide components that are not absorbed by weeds will exist freely in the soil. At present, most of the chemical herbicides used are of the long-residue type, and their residual period in the soil can generally reach more than 36 months. According to the survey, 20% to 70% of the herbicides commonly used in production will remain in the soil for a long time, thereby polluting the soil, groundwater, and food. [0004] Not conducive to crop production: crops will absorb and accumulate herbicides, and their biological tis...
