Description

Technical Field

[0001] The utility model belongs to the technical field of greenhouses, and in particular relates to a transversely movable snow removal mechanism suitable for multi-span greenhouses. Background Art

[0002] To achieve temperature control and promote optimal plant growth, agricultural greenhouses are being upgraded to multi-span greenhouses (multi-span greenhouses). Multi-span greenhouses offer advantages such as better environmental control, lower heating costs, high land utilization, ample internal space, easy expansion, flexible zoning, and a high degree of automation. However, they also have drawbacks such as difficulty in ventilation and rain and snow removal.

[0003] Existing multi-span greenhouses mainly achieve snow removal by installing anti-snow / snow removal equipment on the greenhouse. However, the anti-snow / snow removal equipment has shortcomings such as complex structure, inconvenient use, and easy damage to the greenhouse plastic film. Chinese patent CN 218889047 U discloses "a multi-span greenhouse with built-in snow removal function". By installing a V-shaped opening and closing mechanism above the gutter, the snow in the V-shaped opening and closing mechanism is controlled to fall into the gutter by opening and closing the V-shaped opening and closing mechanism. The water flowing in the gutter is then used to melt the snow, thereby achieving the purpose of snow removal. However, this snow removal method requires the installation of a V-shaped opening and closing mechanism above each gutter, and the cost still needs to be reduced. In addition, the repeated opening and closing actions during actual operation make the components easily damaged, resulting in high maintenance costs. Summary of the Invention

[0004] In view of the above-mentioned technical problems and shortcomings, the purpose of the present invention is to provide a transversely movable snow removal mechanism suitable for multi-span greenhouses, wherein the snow removal mechanism is provided with at least two snow-clearing tracks at the upper end of each arch frame of the multi-span greenhouse along the longitudinal intervals of the multi-span greenhouse, and a snow-clearing driving rope is provided on the snow-clearing track, and a snow-clearing rope is provided between adjacent snow-clearing driving ropes. The snow-clearing driving rope drives the snow-clearing rope to reciprocate laterally along the arch frame to clear the snow into the gutter or outside the group, and then the water flowing in the gutter is used to melt the snow. This mechanism has lower cost and is easier to implement in actual operation. The mechanism is not easy to be damaged and has a longer service life.
