[0003] In the prior art, including the aforementioned patents, an external snow removal device is used to push the snow. However, when the snow is too thick, the device may not be able to remove the snow effectively due to its weight. Furthermore, if the snow removal device scrapes the snow towards both ends of the greenhouse for a long time, it will accumulate at the greenhouse entrance. Moreover, the external device may also malfunction due to the guide rail getting stuck, thus hindering the snow removal work. Utility Model Content

[0008] Furthermore, a stop bar is fixedly installed on one side of the mounting plate, a top block is installed above the worm gear, the top block is slidably connected to the housing, and limit rods are slidably installed on both sides of the lower end of the top block. The upper end of the limit rods is fixedly connected to the housing, and a roller is rotatably installed inside the housing on one side of the winding shaft.

[0009] Furthermore, a spring is fixedly installed on one side of the roller. The spring is arc-shaped, and a hammer is fixedly installed on the other end of the spring. One end of the hammer is rotatably connected to the housing, and the other end of the hammer can be connected to the winding shaft by ropes, steel cables, etc. passing through the roller. A motor is fixedly installed on one side of the hammer, located on the side of the mounting base. The motor is connected to the worm gear via a belt.

[0010] Furthermore, a base is provided at the lower end of the bracket, and a pneumatic rod is fixedly provided at the upper end of the base. The upper end of the pneumatic rod is fixedly connected to the bracket. A movable plate is slidably provided in the middle of the upper end of the base. Slots are provided on both sides of the movable plate, and electrode plates are provided in the slots.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the greenhouse arch with the function of preventing snow accumulation from collapsing is reasonable and has the following advantages:

[0013] (1) The snow removal device is equipped with guide rails, toothed grooves and gears. These components work together to expand the working area of ​​the snow removal device. At the same time, the snow can be loosened by the cooperation of the hammer and top block and other components in the device. The vibration can also be used to force the snow to slide to both sides. Such a snow removal device installed inside the greenhouse has the following advantages: On the one hand, it avoids the obstruction of the normal operation of the device due to the thick snow, and ensures that the snow removal work can be carried out continuously and smoothly. On the other hand, the relatively closed interior of the greenhouse can prevent the guiding components of the device from being blocked by foreign objects. In addition, this layout can also prevent snow from accumulating at the entrances at both ends of the greenhouse, which makes it convenient for workers to enter and exit the greenhouse. In summary, the device reduces the interference of external factors on the device while ensuring snow removal efficiency.

[0014] (2) When the snow on the greenhouse is too thick, the greenhouse can be pressed down. After being pressed down, the relevant components can supply power to the snow removal components. At this time, the snow removal components start to work. When the snow is cleared, the greenhouse will rebound under the action of the air pressure rod. At this time, the snow removal device is de-energized. This can prevent the device from working for a long time and wasting energy. It also does not require workers to supervise or manually start the snow removal device. This can save energy and allow the device to be opened in time to avoid unnecessary losses.

The upper end of the limiting rods 15 is fixedly connected to the housing 6. A roller 16 is rotatably installed inside the housing 6 on one side of the winding shaft 10.

[0028] In this embodiment, a spring 17 is fixedly installed on one side of the roller 16. The spring 17 is arc-shaped. A hammer 18 is fixedly installed on the other end of the spring 17. One end of the hammer 18 is rotatably connected to the housing 6. The other two ends of the hammer 18 can be connected to the winding shaft 10 by ropes, steel cables, etc. after passing through the roller 16. A motor 19 is fixedly installed on one side of the hammer 18 on the side of the mounting base 4. The motor 19 is connected to the worm gear 7 by a belt.

[0029] In this embodiment, a base 20 is provided at the lower end of the bracket 1, and a pneumatic rod 21 is fixedly provided at the upper end of the base 20.

[0031] Working principle: When snow accumulates on the greenhouse, the weight of the snow causes the greenhouse and support 1 to move downwards under pressure. After the support 1 moves downwards, the electrode post 24 connects with the electrode plate at the lower part of the settling trough 23. The electrode plate on one side of the guide rail 2 is then energized, and the motor 19 is energized and started, driving the worm gear 7 to rotate. During the rotation of the worm gear 7, on the one hand, the snow removal device is moved by the gear 5, and on the other hand, the worm wheel 8 is rotated synchronously. When the worm wheel 8 rotates, the ratchet 9 drives the winding shaft 10 to start winding, and the winding force pulls down the hammer 18. When the pawl 11 is disengaged by the stop bar 13, the spring 1... 7. The hammer 18 is reset and strikes the top block 14. The top block 14 vibrates from the strike, thereby loosening the snow on the greenhouse and causing it to slide to both sides. After the hammer 18 is reset, it can also drive the winding shaft 10 to reset, ready for the next operation. When the mounting base 4 moves to the end of the guide rail 2, the inclined surfaces at both ends of the movable plate 22 are used to slide it to one side of the mounting base 4. In this way, the electrode plate on the guide rail 2 changes its energized position due to the change in the position of the movable plate 22. Because only one electrode plate on the guide rail 2 is in the conductive state at the same time, the reciprocating motion of the snow removal device can be realized.
