[0043] In this embodiment, a speed regulating motor 8 is fixed on a support rod to which a seat bearing 10 is fixed, and the output shaft of the speed regulating motor is connected to the first rotating shaft 11 through a chain transmission. Specifically, a third sprocket is fixed to the output shaft of the speed regulating motor 8, a fourth sprocket is fixed to the end of the first rotating shaft 11, and the third sprocket and the fourth sprocket are connected through a transmission chain 9. During the operation of the speed regulating motor 8, the torque is transmitted to the first rotating shaft 11 through the transmission chain 9, and the first rotating shaft 11 can drive the film collector 14 to rotate. The film collector 14 can be rotated to wrap the film around the film collector, thereby realizing film peeling. At the same time, the film peeling speed of the film collector can be adjusted by adjusting the rotation speed of the speed regulating motor 8.

[0044] like Figure 3 to Figure 4 As shown, the film collector 14 includes a large end disc 26 and a small end disc 27. The diameter of the large end disc 26 is larger than the diameter of the small end disc 27. The centers of the large end disc 26 and the small end disc 27 are fixedly connected by a central shaft 28. The large end disc 26 and the small end disc 27 are also connected by a plurality of connecting shafts 29, which are arranged at intervals along the circumferential edges of the large end disc and the small end disc. One end of the connecting shaft 29 is rotatably connected to the large end disc 26, and the other end of the connecting shaft 29 is connected to the small end disc 27 through the film collector retracting mechanism 15. Therefore, the diameter of one end of the film collector 14 is fixed, and the diameter of the other end is adjustable.

[0045] The film collector retracting mechanism 15 includes a connecting shaft sleeve 32 fixedly connected to the connecting shaft, a disc sleeve 31 fixedly connected to the small end face disc, and a connecting rod 30 located between the connecting shaft sleeve and the disc sleeve, and the two ends of the connecting rod 30 are respectively connected to the connecting sleeve by connecting bolts. When the connecting bolts are loosened, the connecting rod and the connecting sleeve are in a rotationally connected state, and the connecting shaft 29 can rotate around the connection with the large end face disc. At this time, the spacing between the connecting shafts facing one end of the small end face disc can be adjusted accordingly, thereby realizing the adjustable diameter of one end of the film collector. When the diameter of this end of the film collector is reduced, it is convenient to remove the film wrapped on the film collector.

[0046] like Figure 5 As shown, the open-close bearing seat 19 includes an upper bearing seat 34 and a lower bearing seat 35. The bottom surface of the lower bearing seat 35 is fixedly connected to the support rod 33, and the lower bearing seat 35 is rotatably connected to the upper bearing seat 34 above it. A fixed groove 37 is provided on one side of the lower bearing seat 35, and a fixed snap ring 36 is rotatably connected on the same side of the upper bearing seat 34. When the fixed snap ring 36 is rotated to be embedded in the fixed groove 37, the fixed connection between the upper bearing seat 34 and the lower bearing seat 35 can be achieved, and the open-close bearing seat 19 is in a closed state. When the fixed snap ring 36 leaves the fixed groove 37, the upper bearing 34 and the lower bearing seat 35 are in a rotatably connected state, and the open-close bearing seat 19 is in an open state.

[0047] In this embodiment, the distance between the two rotary tillers 22 is adjustable. The rotary tillage gearbox 21 connected to the two rotary tillers 22 is respectively arranged on the soil-raising device connecting rod 39. The soil-raising device connecting rod 39 includes a vertical rod and a horizontal rod connected vertically, the front end of the horizontal rod is sleeved on the front part of the frame 1 through a U-shaped bolt 7, the rear end of the horizontal rod is fixedly connected to the top end of the vertical rod, and the box body of the rotary tillage gearbox 21 is fixed on the vertical rod. The rear end of the horizontal rod is fixedly connected to the connecting sleeve 6 through a bolt.

[0048] When it is necessary to adjust the distance between the two rotary tillers 22, loosen the U-shaped bolt connecting the horizontal rod and the front end of the frame, and the bolt between the horizontal rod and the connecting sleeve. At this time, the two soil-raising device connecting rods 39 are in a movable state. During the sliding process of the soil-raising device connecting rods 39 along the front end of the frame, the distance between the two soil-raising device connecting rods 39 changes, thereby driving the two rotary tillage gear boxes 21 and the spacing between the two rotary tillers 22 to change, thereby realizing the adjustment of the spacing between the two rotary tillers 22 to adapt to tobacco fields with different ridge widths.

[0049] When the distance between the two rotary tillers 22 is adjusted to the right position, the U-shaped bolt at the front end of the soil-raising device connecting rod and the bolt between the soil-raising device connecting rod and the connecting sleeve are tightened to fix the position of the soil-raising device connecting rod, thereby fixing the distance between the two rotary tillers.

[0050] The working process of the utility model is as follows. Before operation, first adjust the distance between the two loosening shovels 24 and the distance between the two rotary tillers 22 according to the ridge width. Loosen the bolts between the horizontal guide tube 25 of the loosening shovel and the guide sleeve at the top of the vertical guide tube of the loosening shovel. During the horizontal sliding of the guide sleeve along the horizontal guide tube 25 of the loosening shovel, the spacing between the two loosening shovels 24 can be adjusted. When the relative position between the telescopic tube 40 of the loosening shovel and the vertical guide tube 23 of the loosening shovel is adjusted, the vertical position of the loosening shovel can be adjusted, thereby adjusting the loosening depth of the loosening shovel. When the distance between the two soil-raising device connecting rods 39 is adjusted, the distance adjustment between the two rotary tillers 22 can be achieved.

[0051] When the tractor drags the machine forward through the traction plate 3, the loosening shovel 22 loosens the soil covering the ground film, and the speed regulating motor 8 is activated to drive the film collector 14 to rotate, so that the ground film is wound around the film collector 14 to complete the film peeling operation. During the working process, the speed of the speed regulating motor 8 is adjusted according to the forward speed of the tractor to control the film peeling speed. The rotary tilling blades 22 on both sides lift the soil between the ridges, and the rotary tilling blade shields 20 guide the soil to the ridges to complete the soil cultivation operation.

[0052] After all operations in the tobacco field are completed, the retractable bearing seat 19 is opened, and the first latch 12 and the second latch 16 are pulled out, and the entire film collector 14 can be removed from the machine. At this time, the film collector retracting mechanism 15 is activated, and the connecting rod 30 in the film collector retracting mechanism 15 swings along the axial direction of the film collector 14, so that the diameter of one end of the film collector 14 is reduced, so that the film wrapped on the film collector can be quickly removed.
