[0042] In one embodiment of the present application, the third sliding table 403 is fixedly connected with a first clamping block 411 at the side away from the second sliding table 402, the first sliding table 401 is fixedly connected with a first support 412 at one side of the top, the first support 412 is fixedly connected with a first cross rod 413 at one side, the first cross rod 413 is rotatably connected with a push rod 414 at one end, the push plate 304 is provided with a second clamping block 415 at one end and at the side close to the third sliding table 403, and the push block 406 and the push rod 414 are both provided with inclined surfaces at the opposite sides, and the torsional spring (not shown in the figure) is installed at the rotatable connection position of the first cross rod 413 and the push rod 414;

[0043] As Figure 7As shown, the first clamping block 411 and the second clamping block 415 can be clamped to each other, when the second sliding table 402 is driven to move by the push plate 304, the first clamping block 411 and the second clamping block 415 are clamped, the push block 406 on the second sliding table 402 moves synchronously and compresses the first spring 407 to store energy, when the push block 406 moves to the end of the push rod 414 and the inclined surface of the push block 406 abuts against the inclined surface of the push rod 414, the continuous movement of the push block 406 will push the push rod 414 to rotate around the connection between the push rod 414 and the first horizontal rod 413, so as to make the second clamping block 415 on the push rod 414 and the first clamping block 411 disengage, at this time, the first spring 407 is in contact with the force and releases the elastic potential energy to push the third sliding table 403 to pop out quickly in the direction away from the push block 406, the movement of the third sliding table 403 will drive the second top rod 409 and the second paddle 410 connected at the end of the second top rod 409 to move, so that the second paddle 410 hits on the film, and the energy is transmitted to the film through the second paddle 410, and the energy is transmitted to the foreign matter outside the film through the film, so as to knock the foreign matter outside the film, so as to remove some foreign matters which are not easy to roll or slide, and also facilitate to remove some foreign matters which are not easy to be removed by the first paddle 301 and are closely adhered to the film;

[0045] It should be noted that the second paddle 410 can adopt a hollow shape as shown in Figure 7 The material of the second paddle 410 includes but is not limited to rubber material, and the purpose is to avoid the second paddle 410 to pierce the film when it hits the film, the hollow shape of the second paddle 410 can also reduce the impact force when it collides with the film to a certain extent, for some films which are thick and not easy to be damaged, the second paddle 410 can adopt the same general plate material as the first paddle 301;

[0046] Furthermore, when the push plate 304 moves, the first tapping plate 301 of the vibrating tapping device 3 acts on the film first. At this time, the film is already under a certain degree of tension. If the second tapping plate 410 directly taps the connection between the first tapping plate 301 and the film, the film will be easily damaged due to excessive force. Therefore, in this embodiment, the second tapping plate 410 should maintain a certain distance from the first tapping plate 301.

The bottom of the first rod body 3021 is rotatably connected to the inner wall of the first cylinder 303. One end of the second rod body 3022 passes through the first rod body 3021, the first cylinder 303 and the impact plate 307 in sequence and is slidably connected to the inner wall of the first rod body 3021, the first cylinder 303 and the impact plate 307.

[0052] When the vehicle body 2 moves on the first track 1, the first top rod 302 and the second top rod 409 can both keep tangent to the hemispherical greenhouse, but the difficulty of foreign matter adhesion is different for the film close to the top position and the film close to the top position, and the difficulty of foreign matter removal is also different under the action of the first beating plate 301 and the second beating plate 410, the film close to the top position of the hemispherical greenhouse is more likely to be retained when the foreign matter falls on the film surface due to the smaller angle between the tangent and the horizontal plane, and the film close to the top position is more likely to be retained than the film close to the bottom position.

[0053] By arranging the arc-shaped plate 9 and the second sliding groove 10 in a semi-elliptical shape, the second rod body 3022 can be extended or retracted relative to the first rod body 3021, and during the movement of the vehicle body 2 to the top position of the first track 1, the counterweight 13 cooperates with the arc-shaped plate 9 to continuously rotate, so that the second rotating shaft 11 gradually moves to the middle of the second sliding groove 10, at this time, the second rotating shaft 11 is farthest from the center of the arc-shaped plate 9, and the second rod body 3022 is elongated to the longest state, so that the height of the first beating plate 301 driven by the push plate 304 is higher than that of other positions, the inclination angle of the film at this position is larger, so as to facilitate the removal of foreign matter, and at the same time, the second beating plate 410 can further remove the foreign matter.

[0054] In an embodiment of the present application, the first track 1 is fixedly connected with a sliding block 14 at the bottom of both ends, and a horizontal annular track 15 is arranged below the first track 1, and the two sliding blocks 14 are in sliding connection with the annular track 15, as shown in Figure 8 By rotating the first track 1, the position of the vehicle body 2 can be adjusted, so that multiple first tracks 1 and vehicle bodies 2 are not needed to clean the film on the outside of the hemispherical greenhouse from multiple directions, the equipment cost is saved, the occupation of the internal space of the greenhouse is reduced, and the convenience of the protection device is improved.
