An orchard weeder

Abstract

The invention discloses an orchard weeding machine. The orchard weeding machine comprises a frame and a drag bar fixedly installed on the frame. A weeding device is rotationally installed at the bottom of the frame. A weed raking device is rotationally installed behind the weeding device. The weeding device is rotationally connected with one end of a first connecting rod. The other end of the first connecting rod is rotationally connected with an axle located at the rear portion of the frame. Depth limiting wheels are rotationally installed at the two ends of the axle. A lifting mechanism for adjusting the height of the frame is installed between the frame and the axle. The orchard weeding machine is simple in structure; the height of the weeding device and the height of the weed raking device can be indirectly adjusted through the lifting mechanism, and the orchard weeding machine can be well suitable for being used in orchards in different geographical environments; meanwhile, the weed raking device is further arranged on the weeding machine, weeds buried in soil can be raked out through the weed raking device, the use effect is good, weeding is complete, manufacturing cost is low, weeding efficiency is high, and the orchard weeding machine can be applied and popularized generally.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and equipment, and in particular relates to an orchard weeder. Background technique [0002] At present, in orchard weeding methods, chemical weeding and artificial weeding are mainly used. When chemical herbicides are sprayed, they will pollute the branches and leaves of fruit trees, and there may be residual toxic substances in the fruit, which is not conducive to the development of green agriculture. Artificial weeding often requires a lot of work. Manpower input, in view of the current situation where the agricultural population is decreasing and the planting area is expanding, it is not practical to simply rely on farmers to pull weeds with their hands or use simple farm tools to weed. Manual weeding cannot make scientific and effective use of the labor value of farmers. Therefore, it is necessary to break through the tradition and adopt automatic mechanized means to weed, impr...

[0002] At present, in orchard weeding methods, chemical weeding and artificial weeding are mainly used. When chemical herbicides are sprayed, they will pollute the branches and leaves of fruit trees, and there may be residual toxic substances in the fruit, which is not conducive to the development of green agriculture. Artificial weeding often requires a lot of work. Manpower input, in view of the current situation where the agricultural population is decreasing and the planting area is expanding, it is not practical to simply rely on farmers to pull weeds with their hands or use simple farm tools to weed. Manual weeding cannot make scientific and effective use of the labor value of farmers. Therefore, it is necessary to break through the tradition and adopt automatic mechanized methods to weed, improve work efficiency and save manpower input

However, there are currently large-scale weeding machines that are suitable for weeds in gardens or courtyards, but are not suitable for weeding operations in orchards that exist between mountain depressions, and are easy to damage the roots of fruit trees during the weeding process, and weeding is not thorough, and the efficiency is low. to popularize
