[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1:

[0028] See also Figure 1-5, a closed retracting and releasing device for a salt film cover, comprising a main body 1, a retracting mechanism, an adjusting mechanism and a pulling and releasing mechanism, the retracting mechanism comprising a retracting motor 2, a retracting frame 3, a covering piece 4 and a connecting rod 5, the retracting motor 2 is fixedly mounted on the main body 1, the retracting frame 3 is mounted inside the main body 1 and is rotatably connected to the main body 1, one end of the retracting frame 3 is fixedly connected to the output end of the retracting motor 2, one end of the covering piece 4 is fixedly connected to the retracting frame 3, the connecting rod 5 is fixedly connected to one end of the covering piece 4, the adjusting mechanism comprises a movable plate 6, a roller 7, a limiting rod 8, a first roller 9 and a fixed assembly, the movable plate 6 is mounted inside the main body 1 and is slidably connected to the main body 1, the roller 7 is mounted on the movable plate 6 and is rotatably connected to the movable plate 6, the limiting rod 8 is arranged at both ends of the movable plate 6, the first roller 9 is mounted inside the limiting rod 8 and is rotatably connected to the limiting rod 8.

[0029] In this embodiment, the retraction mechanism includes a retraction motor 2, a retraction frame 3, a covering piece 4 and a connecting rod 5. When in use, the retraction motor 2 is driven to drive the retraction frame 3 to rotate inside the main body 1. At this time, the covering piece 4 installed on the retraction frame 3 rotates inside the retraction frame 3 under the action of the positioning block 20, and the connecting rod 5 fixedly connected to one end of the covering piece 4 is retracted accordingly, and during this process, the connecting ring 15 installed inside the connecting hole on the connecting rod 5 also slides accordingly.

[0030] In this embodiment, the adjustment mechanism includes a movable plate 6, a roller 7, a limit rod 8, a first roller 9 and a fixed component. During use, after the covering sheet 4 moves out between the two rollers 7, it may be necessary to adjust the angle of the covering sheet 4 due to the different heights of the salt field ridges. At this time, the block 11 is pressed in the card hole 23. At this time, the block 11 disengages from the card hole 23 and squeezes the spring 10. At the same time, the limit block 12 on the block 11 slides in the limit slot inside the movable plate 6. When the block 11 disengages from the card hole 23, the limit rod 8 is pulled to slide in the first slot 24 on the main body 1, thereby adjusting the position of the movable plate 6. The covering sheet 4 rotates in the first roller 9 during the process of being retracted or pulled out. When the movable plate 6 is adjusted to the appropriate position, the compressed spring 10 exerts force to push the block 11 into the card hole 23, thereby fixing the position of the movable plate 6.

[0031] In this embodiment, the pulling and releasing mechanism includes a pulling and releasing motor 13, a traction rope 14, a connecting ring 15, a second pulley 16 and a fixing frame 17. When in use, the pulling and releasing motor 13 is driven to drive the pulling and releasing disc 26 to rotate, so that the traction rope 14 slides in the traction hole 22 and drives the second pulley 16 to rotate on the fixing frame 17. At this time, the position of the fixing frame 17 is placed at the other end of the ridge, and the ground nail 18 is inserted to fix the fixing frame 17. When the traction rope 14 slides, it pulls the connecting port 21, so that the connecting rod 5 moves accordingly, thereby pulling out the covering piece 4. When removing the fixing frame 17, use a tool to lift the rocker 19 of the ground nail 18, thereby pulling out the ground nail 18 to complete the removal.

[0032] Example 2:

[0033] To sum up, when in use, the pulling discharge motor 13 is driven to drive the pulling and releasing disc 26 to rotate, so that the traction rope 14 slides in the traction hole 22, and drives the second pulley 16 to rotate on the fixing frame 17. At this time, the position of the fixing frame 17 is placed at the other end of the field ridge, and the ground nail 18 is inserted to fix the fixing frame 17. When the traction rope 14 slides, it pulls the connecting port 21, so that the connecting rod 5 moves accordingly, thereby pulling out the covering piece 4. When removing the fixing frame 17, use a tool to tilt the rocker 19 of the ground nail 18, so as to pull out the ground nail 18 and complete the removal. When it needs to be retracted, the retraction motor 2 is driven to drive the retraction frame 3 to rotate inside the main body 1. At this time, the covering piece 4 installed on the retraction frame 3 rotates inside the retraction frame 3 under the action of the positioning block 20, and the connecting rod 5 fixedly connected at one end of the covering piece 4 is retracted accordingly, and During this process, the connecting ring 15 installed inside the connecting hole on the connecting rod 5 also slides accordingly. During the above retraction or pulling and releasing process, after the covering piece 4 walks out between the two rollers 7, it may be necessary to adjust the angle of the covering piece 4 out due to the different heights of the salt field ridges. At this time, the block 11 is pressed in the card hole 23. At this time, the block 11 disengages from the card hole 23 and squeezes the spring 10. At the same time, the limit block 12 on the block 11 slides in the limit slide groove inside the movable plate 6. When the block 11 disengages from the card hole 23, the limit rod 8 is pulled to slide in the first slide groove 24 on the main body 1, thereby adjusting the position of the movable plate 6. The covering piece 4 rotates in the first roller 9 during the process of being retracted or pulled and released. When the movable plate 6 is adjusted to the appropriate position, the compressed spring 10 exerts force to push the block 11 into the card hole 23, thereby fixing the position of the movable plate 6.

[0034] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
