Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse, in particular to a snow treatment device for greenhouse. Background Art

[0002] A greenhouse is a modern agricultural facility, whose main purpose is to solve the limitation of natural conditions on the plant growth season by simulating and creating a suitable climate environment. In the greenhouse, means such as warming, heat preservation, cooling, ventilation, control system and irrigation system can be used to provide the most suitable growth environment for plants.

[0003] In the snowy environment in winter, the greenhouse will be affected by snow accumulation. The snow on the top of the greenhouse will block the sunlight, resulting in a decrease in the temperature inside the greenhouse. Such a sudden temperature change will affect the growth of plants. Especially during the process of snow melting, a large amount of heat will be absorbed, further reducing the temperature inside the greenhouse. In addition, if the snow accumulation is too thick, it will increase the pressure on the greenhouse structure. When it exceeds a certain threshold, it may cause the greenhouse to collapse, resulting in economic losses and potential dangers. Snow accumulation not only affects the lighting conditions and temperature inside the greenhouse, but also increases the pressure on the greenhouse structure. Therefore, the snow on the greenhouse needs to be cleared in time.

[0004] The traditional snow clearing method is to manually use a snow shovel or a blower to clear snow. The traditional snow clearing method has the problems of high labor intensity and low snow clearing efficiency. The disadvantage of the snow shovel is that the length of the handle is limited. When the operator clears snow on the ground, it is often impossible to clean the top of the greenhouse, resulting in incomplete snow clearing. The disadvantage of the blower is that the blowing distance is limited, and the same problem of incomplete snow clearing will occur. Moreover, for relatively thick snow accumulation, the blower cannot achieve a good snow clearing effect. Summary of the Utility Model

Then, the push rod of the driving device 203 extends, driving one end of the first rod 4011 to move forward. At this time, the telescopic rod 4 gradually contracts, bringing the snow shovel 5 back to the initial position. Then, the motor 103 drives the driving rod 104 to rotate, and further drives the roller 105 to rotate, moving the first driving assembly 1 and the second driving assembly 2 forward along the sliding rail 3. When reaching the designated position, the first driving assembly 1 pauses working. Then, the second driving assembly 2, the telescopic rod 4 and the snow shovel 5 repeat the snow pushing work.

[0046] During the whole working process, by controlling the movement of the first driving assembly 1 on the sliding rail 3, the initial position of the snow shovel 5 before snow pushing is adjusted. In this way, as the first driving assembly 1 drives the second driving assembly 2 to move and pause on the sliding rail 3, the snow shovel 5 can rhythmically perform partial snow clearing along the direction of the sliding rail 3 until the snow clearing work of the entire greenhouse top is completed. Moreover, as the driving assembly moves, the snow in the sliding rail 3 can be cleared by the snow clearing device 7, and the snow that the snow shovel 5 fails to clear can be further cleared by the snow clearing brush 8.
