[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the utility model.
[0023] See also Figure 1-4 The two ends of the two-way screw 10 are connected to each other, and the two ends of the two-way screw 10 are connected to each other by screw thread.
[0024] The inner bottom end of the mounting frame 1 on the other side is fixedly connected to a connecting frame 12, and both ends of the connecting frame 12 are rotatably connected to a threaded rod 18, and the middle part of the threaded rod 18 is threadedly connected to a second threaded block 14, and the inner sides of the first threaded block 11 and the second threaded block 14 are fixedly connected to a cutting plate 7, and the blade structure at the bottom end of the cutting plate 7 cuts against the rubber sheet 6 to complete the weed cutting operation. A roller 4 is rotatably connected between the two mounting frames 1, and the rotation of the roller 4 is driven by the drive shaft 15 structure, thereby turning over the ground in the farmland through the cutter head body 5, and during the working process, the weeds will be entangled in the rotating positions of the two ends of the roller 4, which can be driven by the first motor 2 and the second motor 16 at this time. Both ends of the roller 4 are fixedly connected with a rubber sheet 6, which increases the contact with the roller 4 during the cutting process of the cutter, thereby preventing the cutter head from being stuck and affecting the use, and the rubber sheet 6 is easy to replace. Several cutter head bodies 5 are fixedly connected to the outside of the roller 4. The two ends of the outside of the mounting frame 1 on the other side are fixedly connected to the second motor 16. The second motor 16 needs to rotate in the opposite direction, which can move the two second threaded blocks 14 closer to the middle, so as to facilitate cutting the weeds at the other end again. The driving end of the second motor 16 is fixedly connected to the fourth bevel gear 17, which will drive the third bevel gear 13 to rotate. After rotation, it can drive the rotation operation of the threaded rod 18. After rotation, the second threaded block 14 is moved. One side of the fourth bevel gear 17 is engaged with the third bevel gear 13, and the third bevel gear 13 and the threaded rod 18 are fixedly connected. The interior of the mounting frame 1 on the other side is penetrated by a drive shaft 15. By connecting the mounting frame 1 to the agricultural vehicle and then connecting it to the drive equipment through the drive shaft 15, the drive shaft 15 and the roller 4 are fixedly connected.
[0025] Working principle: When in use, first connect the mounting frame 1 to the agricultural vehicle, and then connect it to the driving device through the drive shaft 15. The drive shaft 15 structure drives the roller 4 to rotate, so that the ground in the farmland is overturned through the cutter head body 5. During the working process, weeds will be entangled at the rotating positions at both ends of the roller 4. At this time, the first motor 2 and the second motor 16 can be used to drive the first bevel gear 8 and the fourth bevel gear 17 respectively. The first bevel gear 8 can drive the second bevel gear 9 to rotate, thereby driving the rotation of the bidirectional screw 10. After rotation, The first threaded block 11 is threadedly engaged, so that the first threaded block 11 can be moved closer to or away from the middle, thereby driving the blade structure at the bottom end of the cutting plate 7 to cut the rubber sheet 6 in contact, thereby completing the weed cutting operation; and the fourth bevel gear 17 will drive the third bevel gear 13 to rotate, and after rotation, it can drive the rotation operation of the threaded rod 18, and after rotation, the second threaded block 14 is moved. Since the two second motors 16 need to rotate in opposite directions, the two second threaded blocks 14 can be moved closer to the middle, thereby facilitating the weed cutting process at the other end again.

Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
