AI Technical Summary
Existing weeding machines for walnut trees are difficult to control precisely in terms of distance from the trees. This results in damage to the trunk or root system when the machine is close to the tree, and incomplete removal of weeds when it is far away, thus affecting weeding efficiency.
A weeding machine for walnut trees was designed, comprising a telescopic swing arm, a U-shaped clamp, a rotating roller, and a torque-adjusting screw. The telescopic swing arm connects to the clamp of the walnut tree, adjusting the distance between the weeding machine and the tree to ensure stable weeding operations. The rotating roller reduces friction and enables circumferential weeding.
This effectively avoids physical damage when the weeder approaches the walnut tree, ensures thorough weed removal, improves weeding efficiency, and reduces the need for manual cleaning.
