[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Chemical weeding is an important method for controlling rice weeds, but long-term, large-scale, and high-frequency application of pesticides can easily lead to many problems such as weed resistance, crop damage, and environmental pollution. Developing environmentally friendly mechanical weeding and reducing the use of herbicides are the key to sustainable agricultural development. Therefore, this weeding equipment is needed. When using this equipment, it should be noted that before using the device, ensure that the drive device 1 and the cutting mechanism 3 are in normal working condition to avoid accidental injuries. After use, clean up the residue on the weeding device in time to avoid accumulation that affects the next use. During the operation, especially when dealing with longer weeds, pay attention to prevent the roller 209 and the weeding blade 210 of the weeding mechanism 2 from being blocked by weeds, and clean up the blockage in time.

[0022] It should be noted that during use, the telescopic rod 204 is first started to drive the first connecting frame 203 to move through the second connecting plate 206 and the connecting block 205, so that the fixed rod 201 moves up and down along the first connecting plate 202, and at the same time, the rotating shaft 208 on the fixed frame 207 drives the roller 209 and the weeding blade 210 to rotate to contact the weeds for weeding. The worker only needs to control the direction to achieve weeding, which reduces the workload of the workers and improves work efficiency.

[0024] It should be noted that, during use, first align the through holes on the second connecting frame 303 and the fixing plate 301, then manually insert the pin 302 for fixing, and then the servo motor 304 drives the connecting rod 305 to rotate while driving the rotating disk 306 and the cutting blade 307 to rotate. The setting of the cutting mechanism 3 enables the weeds to be quickly cut off during the rotation process, thereby improving the cutting efficiency, reducing the interference of the weeds on the driving device 1, and extending the service life of the driving device 1.
