The end of the rotating shaft 3 is fixedly connected to the turntable 4. The moving frame 7 is slidably installed inside the turntable 4. The moving frame 7 is fixedly connected to the positioning rod 8 and the coupling shaft 10. The positioning rod 8 is clamped with the film covering cylinder 5. The coupling shaft 10 is rotatably installed on the auxiliary frame 11. The connecting rod 13 is rotatably installed on the auxiliary frame 11 and the main frame 12. The hydraulic cylinder 14 is fixedly installed at the top of the transplanter mounting frame 1. The hydraulic rod of the hydraulic cylinder 14 is fixedly connected to the main frame 12.

[0038] Through the above replacement mechanism, after the film 6 on the film covering cylinder 5 is used up, the hydraulic cylinder 14 is started, so that the main frame 12 moves upward. The main frame 12 drives the auxiliary frame 11 to move horizontally through the connecting rod 13. Furthermore, the coupling shaft 10 can be moved horizontally. The coupling shaft 10 drives the positioning rod 8 to move through the moving frame 7, so that the positioning rod 8 moves out of the positioning groove 9. Then, the film covering cylinder 5 is pulled, and the film covering cylinder 5 can be quickly removed and replaced, which is more convenient to replace and reduces the labor intensity.

[0039] Specifically, a power motor 15 is fixedly arranged on the side of the support plate 2. The output end of the power motor 15 is fixedly provided with a main gear 16. A secondary gear 17 is fixedly sleeved on the outside of one turntable 4. The main gear 16 meshes with the secondary gear 17.

[0040] Through the above structure, when the power motor 15 is started, the main gear 16 can drive the secondary gear 17 to rotate. In this way, the turntable 4 can be rotated, and then the film covering cylinder 5 can be rotated for film covering treatment.

[0041] Specifically, a splicing block 18 is fixedly arranged on the film covering cylinder 5. Four splicing grooves 19 are formed on the turntable 4. The splicing block 18 is clamped with the splicing groove 19.

[0042] With the above structure, an assembly block 18 is aligned with an assembly groove 19, so that the assembly block 18 is snapped into the assembly groove 19, which facilitates the limit treatment of the film covering cylinder 5.

[0043] Specifically, the end of the turntable 4 is in contact with the film covering cylinder 5. A film 6 is wound around the film covering cylinder 5. A positioning groove 9 is provided at the end of the film covering cylinder 5. The positioning rod 8 is snap-fitted with the positioning groove 9. It should be noted that the limit treatment of the film covering cylinder 5 is carried out.

[0044] Specifically, a round hole is provided at the end of the rotating shaft 3. The connecting shaft 10 is in contact with the inner wall of the round hole. A sliding hole is provided at the end of the turntable 4. The positioning rod 8 is slidably installed in the sliding hole. It should be noted that it facilitates the lateral movement of the positioning rod 8 and the connecting shaft 10 and can rotate following the rotating shaft 3.

A stable hole is provided on the side wall of the inner groove. A stable block is fixedly provided on the side of the auxiliary frame 11. The stable block is slidably installed in the stable hole. A main hole is provided on the side wall of the back groove. The main frame 12 is slidably installed vertically in the main hole. The side wall of the back groove is in contact with the auxiliary frame 11. It should be noted that it can make the main frame 12 and the auxiliary frame 11 move stably.

[0046] Working principle:

[0047] S1: Start the power motor 15, which can drive the auxiliary gear 17 to rotate by the main gear 16. In this way, the turntable 4 can be rotated, and then the film covering cylinder 5 can be rotated, so that the film 6 is wound out from the film covering cylinder 5 for film covering treatment.

[0048] S2: After the film 6 on the film covering cylinder 5 is used up, start the hydraulic cylinder 14 to move the main frame 12 upward. The main frame 12 drives the auxiliary frame 11 to move horizontally through the connecting rod 13. Then the connecting shaft 10 can be moved horizontally. The connecting shaft 10 drives the positioning rod 8 to move through the moving frame 7, so that the positioning rod 8 is removed from the positioning groove 9. Then pull the film covering cylinder 5, and the film covering cylinder 5 can be quickly removed and replaced. The replacement is relatively convenient and the labor intensity is reduced.

[0049] S3: Prepare a new film covering cylinder 5, and align an assembly block 18 with an assembly groove 19, so that the assembly block 18 is snapped into the assembly groove 19. At this time, the positioning rod 8 is aligned with the positioning groove 9. Then start the hydraulic cylinder 14 to make the positioning rod 8 return to its position and snap into the positioning groove 9, and quickly carry out the installation and limit treatment of the film covering cylinder 5.
