TECHNICAL FIELD
[0001] The utility model relates to a film covering and transplanting machine technical field, especially a film covering and transplanting machine film feeding mechanism with anti -winding function. BACKGROUND
[0002] The film covering and transplanting machine is an agricultural machine that can transplant seedlings while covering the ground with film. It combines the functions of film covering and transplanting, aiming to improve work efficiency, reduce labor costs, and improve soil environment and promote crop growth. However, the film is prone to winding during transportation, which affects the stable operation of the transplanting machine.
[0003] The existing film covering and transplanting machine film feeding mechanism with anti -winding function may affect the stability of the film during transportation when the film tension is too large or too small.

Frequent downtime is required to clean the film winding, which seriously affects the work efficiency. When the film roller is used up, a new film roller needs to be replaced for continuous work. Workers need to disassemble multiple fixed components (such as bolts, buckles, bearing end covers) to remove the film roller.

[0036] Embodiment two:
[0037] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the second embodiment of the utility model is based on the previous embodiment.

[0046] Embodiment three:
[0047] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 5 , the third embodiment of the utility model is based on the first two embodiments.
[0048] Specifically, the driving assembly 10 comprises a motor 101 fixed below the mounting frame 1, and the output end of the motor 101 is provided with a transmission rod 102.
[0049] The motor 101 is powered by an external power supply and is signal-connected with the controller of the transplanter, and the motor 101 drives the transmission rod 102 to move in a circle after being started.
[0050] Specifically, the guide assembly 11 comprises a guide block 111 fixed on the outer side of the moving block 12, and the inner wall of the fixed frame 2 is provided with a guide groove 112, and the outer side of the guide block 111 is slidingly connected with the inner wall of the guide groove 112.
[0051] When the moving block 12 moves, the guide block 111 slides along the inner side of the guide groove 112, and the guide groove 112 limits the movement path of the guide block 111, so that the moving block 12 moves vertically according to the predetermined track.
[0052] Specifically, the transmission assembly 13 comprises a pushing block 131 fixed on one end of the transmission rod 102, and the inner wall of the moving block 12 is provided with a horizontal groove 132, and the outer side of the pushing block 131 is slidingly connected with the inner wall of the horizontal groove 132.

[0054] Specifically, the balance assembly 14 comprises a fixed block 141 fixed on one side of the fixed frame 2, and the bottom of the fixed block 141 is fixedly connected with a tension spring 142.

[0056] Specifically, the bottom end of the tension spring 142 is fixedly connected to the top of the moving block 12.
[0057] The tension generated by the tension spring 142 can balance during the lifting and moving of the moving block 12, thereby improving the stability.
[0058] In use, when the film roller 7 needs to be disassembled, the knob 42 is first driven to rotate the positive and negative screw rods 41, so that the two sets of threaded sleeves 5 move in opposite directions in parallel, the bearing seat 61 and the connecting seat 62 are separated from the film roller 7, at the same time, the positioning block 81 and the clamping block 91 are respectively separated from the inner side of the limiting groove 82 and the clamping groove 92, and then the film roller 7 is limited, and the disassembly is completed. When installing, the knob 42 is rotated, so that the two sets of threaded sleeves 5 move to the middle point of the positive and negative screw rods 41 at the same time, the bearing seat 61 moves at the same time, and the positioning block 81 and the clamping block 91 are respectively inserted into the inner side of the limiting groove 82 and the clamping groove 92, so that the position of the film roller 7 is fixed, and the installation is completed. When the tension roller 15 detects that the film conveying tension deviates from the set range, a signal is transmitted to the controller, and the controller starts the motor 101 according to the signal content, and then the motor 101 drives the transmission rod 102 to rotate counterclockwise, drives the shifting block 131 to move in a circle, and the shifting block 131 slides along the inner side of the horizontal groove 132, pushes the moving block 12 to move downward, and the two tension springs 142 balance the stability of the moving block 12 during movement, so that the moving block 12 drives the tension roller 15 to vertically descend, so that the film is stretched, and when the film tension reaches the set range, the movement of the tension roller 15 stops, so that the film does not appear to be stacked and wound.
[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit it. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalent, without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
