Description

Technical Field

[0001] The utility model relates to the technical field of agricultural weeding equipment, in particular to a weeding device for agricultural planting. Background Art

[0002] Agricultural herbicides need to be sprayed onto the target ground with the help of agricultural sprayers. Small, discontinuous plots of farmland need to be manually sprayed with herbicides using a backpack agricultural sprayer. During the operation, the nozzle needs to be swung back and forth to spray the herbicide on the weeds.

[0003] In the prior art with publication (announcement) number: CN220674964U and publication (announcement) date: 2024-03-29, an agricultural weeding device for agricultural facilities is disclosed, which raises the problem that "due to the back-and-forth swinging operation of the nozzle, the arm needs to maintain the elevation angle of the nozzle and needs to remain bent for a long time. This process requires the muscles to be tense all the time, which causes the arms to easily become sore when conventional backpack agricultural sprayers are operated for a long time" and solves the problem raised.

[0004] However, when using the above-mentioned prior art, it is necessary to hold the nozzle with the hand and rest on the nozzle for support. When holding the nozzle with the hand, the arm is horizontal with the nozzle, which will cause the wrist to be bent downward for a long time during operation, and the arm is placed on the circular tube of the nozzle, which is unstable. Therefore, a weeding device for agricultural planting is proposed to optimize the above-mentioned prior art. Utility Model Content
