[0025] Embodiment 1: A tear-proof film covering device for broad bean planting, such as Figure 1-Figure 4As shown, it includes a rotating support roller 1, and a transverse support plate 2 inserted and arranged on the corresponding two sides of the rotating support roller 1, a first limiting guide groove 15 is opened on one side of the transverse support plate 2, the rotating support roller 1 is rotatably arranged inside the first limiting guide groove 15 and extends out of one side thereof, a buffer spring 10 is fixedly connected to one side of the inner wall of the first limiting guide groove 15, a buffer support rod 7 is inserted into the buffer spring 10, a pressure-resistant movable plate 5 is fixedly connected to the side of the buffer support rod 7 away from the buffer spring 10, a buffer support plate 9 is arranged between the pressure-resistant movable plate 5 and the buffer spring 10, a buffer shell 8 is arranged on the outside of the buffer spring 10, the buffer shell 8 is fixedly arranged on one side of the inner wall of the first limiting guide groove 15, the buffer support plate 9 is located inside the buffer shell 8, and when the device is running, the rotating support roller 1 is supported by the transverse support plates 2 at both ends of the rotating support roller 1 and the first limiting guide grooves 15 opened therein The first limit guide groove 15 is used to support the rotating support roller 1 and the outer film material on the outer side thereof, so as to ensure the stability of the rotating support roller 1 and the outer film material when rotating, and to ensure that the rotating support roller 1 can slide upward under the arc support of the first limit guide groove 15 to ensure that the device encounters resistance during the pulling process, and then the pressure-resistant movable plate 5 inside the first limit guide groove 15 is pressure-moved. The movement of the pressure-resistant movable plate 5 will drive the buffer support plate 9 on one side to move simultaneously under the connection of the buffer support rod 7, thereby compressing and moving the buffer spring 10 inside the buffer shell 8. By the elastic support of the buffer spring 10 and the limitation of the buffer shell 8, the effect of buffering when the pressure-resistant movable plate 5 moves is achieved, thereby preventing the rotating support roller 1 and the outer film material from breaking due to the sudden resistance pulling, thereby ensuring the stability of the device when it continues to move when encountering resistance during pulling.

[0026] like Figure 1-Figure 4 As shown, a contact switch 11 is provided in the middle of one side of the buffer spring 10, and the contact switch 11 is located on one side of the buffer support rod 7. The contact switch 11 is fixedly provided on one side of the inner wall of the first limit guide groove 15. The contact switch 11 is electrically connected to an alarm 14, and the alarm 14 is fixedly provided on the outer side of the transverse support plate 2.

When it contacts the contact switch 11, it can turn on the alarm 14 under the connection of the external power supply and the wire, and the alarm 14 emits a sound to remind the user to stop checking.

[0027] like Figure 1-Figure 4 As shown, a limiting support block 6 is fixedly connected to the outer side of the pressure-resistant mobile plate 5, and the limiting support block 6 is slidably arranged on one side of the inner wall of the first limiting guide groove 15. By limiting the sliding position of the limiting support block 6 in the first limiting guide groove 15, the stability of the distance and direction of the pressure-resistant mobile plate 5 when sliding is ensured, thereby improving the stability and reliability of the device during operation.

The end of the guide rod 12 away from the auxiliary block 13 is slidably connected to the first limiting guide groove 15. By supporting the sliding of the guide rod 12 by the first limiting guide groove 15, the pressure-resistant mobile plate 5 is guided and moved under the support of the auxiliary block 13 and the guide rod 12, thereby improving the stability of the pressure-resistant mobile plate 5 when moving in multiple directions.

[0029] like Figure 1-Figure 4 As shown, a vertical support plate 3 is fixedly provided on one side of the transverse support plate 2, and a second limiting guide groove 4 is opened on one side of the vertical support plate 3. One end of the rotating support roller 1 is rotatably set in the second limiting guide groove 4, and the vertical support plate 3 and the transverse support plate 2 are fixedly connected with a fixed support frame 16 at the same time. There are at least two fixed support frames 16, and the rotating support roller 1 is located between the two fixed support frames 16. Through the overall support of the fixed support frames 16 on both sides, and the support and sliding guide limit of the rotating support roller 1 when the transverse support plate 2 and the vertical support plate 3 rotate at the same time, it is ensured that the rotating support roller 1 can slide upward only when it receives greater resistance, thereby improving the rationality of the overall operation of the device.

[0030] Working principle: With the support of the lateral support plates 2 at both ends of the rotating support roller 1 and the first limiting guide groove 15 opened inside thereof, the stability of the rotating support roller 1 and the film material on its outside is ensured during rotation, and the rotating support roller 1 can be ensured to be able to slide upwards when the device encounters resistance during the pulling process under the arc support of the first limiting guide groove 15, and then the pressure-resistant movable plate 5 inside the first limiting guide groove 15 is pressure-moved, and the movement of the pressure-resistant movable plate 5 will drive the buffer support plate 9 on one side to move simultaneously under the connection of the buffer support rod 7, thereby compressing and moving the buffer spring 10 inside it under the limitation of the buffer shell 8, and with the elastic support of the buffer spring 10 and the limitation of the buffer shell 8, the effect of buffering when the pressure-resistant movable plate 5 moves is achieved, thereby preventing the rotating support roller 1 and the film material on its outside from breaking due to the sudden resistance pulling, thereby ensuring the stability of the device when it continues to move when encountering resistance during pulling. The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
