Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse snow removal, in particular to snow melting and snow removal equipment for vegetable greenhouses. Background Art

[0002] With the continuous progress of society, the traditional agricultural production model can no longer meet the needs of the development of modern civilization. Vegetable greenhouses have emerged under this trend. They are not restricted by seasons and are therefore widely used in the field of vegetable breeding to increase crop yields, advance planting or delay planting, and achieve staggered listing of agricultural products, meet people's different needs, and increase farmers' income.

[0003] However, in most parts of my country, especially in the north, there is a lot of snowfall in winter. At present, vegetable greenhouses lack roof snow removal equipment. Whenever there is heavy snow, vegetable farmers deal with the snow on the roof by burning it for heating or cutting the plastic film with a knife. If they are not timely (at night or the roof area is too large, and the manual cutting of the greenhouse is not in place to reduce the pressure), the snow will crush the roof and cause it to collapse, causing huge losses to vegetable farmers.

[0004] The existing snow removal methods for rooftops have gradually exposed their shortcomings in actual operation, mainly in the following aspects:

[0005] First, the method of removing snow by burning combustibles to increase the temperature in the greenhouse can easily cause air pollution and reduce the environmental protection indicators of organic and green vegetables.

[0006] Second, the method of cutting and removing snow can easily cause the temperature inside the greenhouse to drop significantly, resulting in reduced yields in some vegetable fields due to concentrated snow accumulation. In addition, the cracked parts of the roof will need to be repaired later, increasing facility costs.
