The output end of the linkage 13 is in transmission connection with a transmission disc 131, the transmission disc 131 being provided with a transmission boss 132 which is slidingly connected in the driven part 44. In actual use, when the staff drives the transmission disc 131 to rotate through the linkage 13, the transmission disc 131 can drive the transmission boss 132 to move in a circle around the transmission disc 131, and the transmission boss 132 can drive the driven part 44 to move back and forth during the rotation of the transmission boss 132, so that the driven part 44 can drive the connecting column 43 to move the second rack 45 back and forth, which can effectively drive the transmission gear 18 to rotate back and forth, so as to drive the plurality of linkage gears 16 to rotate back and forth, so as to realize the effect of continuously adjusting the position of the cut wormwood.

[0039] It is worth mentioning that in the above embodiment, the linkage between the transmission member 12 and the linkage member 13 can be a transmission belt and a transmission wheel, or a chain and a sprocket, the transmission member 12 includes a motor for providing power and a transmission wheel or a transmission belt for linkage and is externally provided with a housing; further, the linkage between the transmission member 12 and the linkage member 13 and the linkage with the sweep reel 2, the linkage of the linkage member 13 with the transmission disc 131 is provided with a speed reducer, so that the output speed of the transmission member 12 and the linkage member 13 can be effectively adjusted to realize precise control of the sweep reel 2 and the adjusting assembly 3, and the final effect is that the sweep reel 2 stirs the wormwood once, the cutting knife 15 cuts it at the same time, and the adjusting assembly 3 can adjust the position of the cutting completion to achieve the effect of resetting and starting the next round of position adjustment when the next batch of wormwood is cut and laid on the adjusting assembly 3.

[0040] Please refer to Figures 1-4 As a preferred technical solution in the embodiment, the adjusting assembly 3 includes a ring gear 31 fixedly installed on the bucket and an adjusting table 32 rotatably installed on the bucket, the bottom of the adjusting table 32 is fixedly connected with the linkage gear 16, and the ring gear 31 is located between the cutting knife 15 and the feeding auger; the adjusting table 32 is provided with a mounting groove 33, an installation seat 36 is fixedly installed in the mounting groove 33, a bidirectional screw rod 37 is rotatably connected to the installation seat 36, and a collecting unit 38 is transmissionally connected to both ends of the bidirectional screw rod 37. One end of the bidirectional screw rod 37 penetrates through the adjusting table 32 and is provided with a drive gear 39, and the drive gear 39 is in engagement with the ring gear 31. In actual use, after the staff cuts the wormwood, the cut wormwood will be laid between the collecting units 38, at this time, when the staff controls the linkage gear 16 to rotate, the linkage gear 16 can drive the adjusting table 32 to rotate, and the wormwood between the collecting units 38 can be adjusted in position during the rotation of the adjusting table 32, so that the roots of the wormwood can enter the feeding auger first, thereby effectively avoiding the situation that the stems and leaves enter the auger first during harvesting, causing damage to the stems and leaves and affecting the medicinal value of the harvested wormwood.

[0041] Meanwhile, the drive gear 39 can produce circular motion during the rotation of the adjusting table 32, and since the drive gear 39 is in engagement with the ring gear 31, the drive gear 39 can produce rotation to drive the bidirectional screw rod 37 to rotate, and the two collecting units 38 can be displaced inward during the rotation of the bidirectional screw rod 37, thereby achieving the effect of collecting the wormwood into a bundle.

[0042] The above scheme can effectively avoid the interference between the artemisia during the rotation of the adjusting table 32 and the collecting unit 38, thereby ensuring the stability of the position adjustment of the artemisia during use.

[0043] Please refer to Figures 5-6 As a preferred technical scheme in the embodiment, the collecting unit 38 comprises a sliding block 381 slidingly connected in the mounting groove 33, a threaded hole 382 provided on the sliding block 381 and threadedly connected with the bidirectional screw rod 37, a collecting column 386 provided on the threaded hole 382 and used for collecting the artemisia, a connecting shaft 385 rotatably connected with the bottom of the collecting column 386, a driven gear 384 fixedly connected with the bottom of the connecting shaft 385, and a placing groove 383 provided on the sliding block 381 and used for mounting the driven gear 384. The adjusting table 32 is further provided with a sliding groove 34 for sliding of the driven gear 384, and a first rack 35 provided at the middle portion of the sliding groove 34. When the sliding groove 34 slides to the first rack 35, the driven gear 384 can be engaged with the first rack 35. In actual use, when the driving gear 39 drives the bidirectional screw rod 37 to rotate, the two sliding blocks 381 can be driven to move relatively or oppositely. During the relative movement of the sliding blocks 381, the collecting column 386 can be driven to move relatively, and during the relative movement of the collecting column 386, the driven gear 384 can be driven to move. At this time, the driven gear 384 can be displaced along the sliding groove 34 provided on the adjusting table 32. When the driven gear 384 is displaced to the first rack 35, the driven gear 384 can be engaged with the first rack 35. At this time, the driven gear 384 can just collect the artemisia, and during the displacement of the driven gear 384 on the first rack 35, the driven gear 384 can be self-rotated, and during the self-rotation of the driven gear 384, the collecting column 386 can be rotated. Since the two driven gears 384 are relatively displaced on the first rack 35, the two driven gears 384 can be oppositely rotated, and the two collecting columns 386 can further collect the artemisia. During the self-rotation of the driven gear 384, the artemisia can be conveyed, so that the artemisia can be conveyed into the feeding auger after the position of the artemisia is adjusted.

[0044] The above embodiment has the following technical effects: by providing the driven gear 384 and the first rack 35 and enabling them to be engaged with each other, the artemisia can be collected and conveyed during the displacement of the sliding block 381, so that the artemisia bundle can be smoothly fed into the feeding auger.

The comb tooth 25 is composed of two straight rods, one end of the two straight rods is installed on the installation rod 24, and the other end is connected through a V-shaped bending rod. The distance between the two comb teeth 25 is equal to the distance between the two adjacent collecting units 38 on the adjusting assembly 3, and the distance between the two comb teeth 25 is equal to the distance between the two collecting units 38 when they are opened to the maximum. This kind of setting can reduce the distance between the multiple wormwoods during guiding and realize the effect of harvesting in bundles, so that the roots of the bundled wormwoods enter into the feeding auger under the action of the adjusting assembly 3.

[0046] Please refer to Figure 2 , as a preferred technical solution in the embodiment, one end of the transmission shaft 21 is further connected with an eccentric wheel 26, the eccentric wheel 26 is provided with a plurality of connecting arms 27 matched with the number of support arms 23, and the end of the connecting arm 27 is provided with a support 28 for supporting the installation rod 24.
