[0027] In order to facilitate the pressing of the left and right ends of the film 6 on the grain surface to fix the position of the film 6, as shown in Figure 1 and Figure 2 , the device further comprises first and second lifting drive devices, the first lifting drive device is arranged at one end of the cross beam 3, and the second lifting drive device is arranged at the other end of the cross beam 3. The first lifting drive device is provided with a first pressing roller 7 extending in the front-rear direction, and the ends of the first pressing roller 7 are rotatably connected with the first lifting drive device. The second lifting drive device is provided with a second pressing roller 11 extending in the front-rear direction, and the ends of the second pressing roller 11 are rotatably connected with the second lifting drive device. The first and second pressing rollers 7 and 11 are respectively arranged on the opposite sides of the two first walls 1.

[0028] Specifically, the first lifting drive device comprises two second rotary drive devices 19 fixedly arranged on two cross beams 3, the output shafts of the second rotary drive devices 19 are fixedly provided with second winding rollers, the second winding rollers are fixedly wound with first lifting ropes, the free ends of the first lifting ropes are fixedly connected with the top of first hangers, the first hangers are fixedly provided with first bearings, and the front and rear ends of the first pressing roller 7 are respectively fixedly arranged in the first bearings of the two first hangers.

[0029] The second lifting driving device comprises two third rotary driving devices 14 fixedly arranged on the two cross beams 3, a third winding roller 15 is fixedly arranged on the output shaft of the third rotary driving device 14, a second hoisting rope 16 is fixedly wound on the third winding roller 15, the free end of the second hoisting rope 16 is fixedly connected with the top of the second hanger 13, and the second bearing 12 is fixedly arranged on the second hanger 13.

[0030] As shown in Figure 4 the free end of the film 6 is fixedly embedded in the fixed head 8 extending along the front and back directions, the end of the fixed head 8 away from the film 6 is fixedly provided with a plurality of first rope rings 9 arranged at intervals in front and back directions,

[0031] The free end of the film 6 is tied and connected with the first rope ring 9 at the free end of the first rope 10 after winding around the first pressing roller 7, and the free end of the first rope 10 is connected with the free end of the film 6 through the first rope ring 9 after winding around the second pressing roller 11.

[0032] The rotary driving devices in the embodiment all adopt speed reduction motors, the speed reduction motors are all connected with the controller for control, the controller can adopt a PLC controller or a touch screen control panel, and the controller can be installed at the entrance of the granary.

[0033] Working principle: when the film coating operation is performed, the first electric winding device is controlled to release the film 6 wound on the first winding roller 4, and the second electric winding device is controlled to wind the first rope 10 through the second winding roller 17, so as to pull the film 6 to move from the first pressing roller 7 to the second pressing roller 11 until the free end of the film 6 winds around the second pressing roller 11.

[0034] Then, the first lifting driving device and the second lifting driving device are controlled to slowly lower the first pressing roller 7 to the second pressing roller 11, at the same time, the first electric winding device is controlled to continue to slowly release the film 6 wound on the first winding roller 4, until the first pressing roller 7 presses and covers the film 6 on the grain surface to the second pressing roller 11, then the movement of the first lifting driving device, the second lifting driving device and the second electric winding device is stopped. When the film 6 is wound, the above operation steps are operated in reverse.

[0035] This device can automatically cover and roll up grain surfaces, replacing manual labor. It not only operates quickly, but the lifting and lowering of the first and second pressure rollers 7 and 11 ensures the film 6 is firmly fixed to the grain surface, completing the comprehensive covering process. The fourth rotary drive device 18 and the first rotary drive device 5 are located outside the grain silo, with the first and second pressure rollers 7 and 11 respectively positioned against the surfaces of the left and right first walls 1. This maximizes the coverage area of ​​the film 6 on the grain surface. Simultaneously, the rotation of the first and second pressure rollers 7 and 11 reduces friction on the first rope 10 and the film 6, extending their service life.
