Description

Technical Field

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

[0002] Under natural conditions, the growth of fruit trees requires specific environmental conditions. For example, tropical fruit trees cannot reproduce in the north. Therefore, in winter, if residents in the north want to enjoy tropical fruits, they need to transport them from the south, which undoubtedly increases costs and makes the price of fruits high in winter. The solution is to promote fruit greenhouses in the north (generally including arched frames and plastic films covering them), so that some special varieties of fruit trees can reproduce in the north; at the same time, the growth cycle of fruit trees can also be artificially adjusted so that fruit trees can produce fruits in winter.

[0003] But in winter, fruit greenhouses in the north are often tested by heavy snow. When the snow on the plastic film of the fruit greenhouse reaches a certain thickness in winter, it will damage the plastic film and even cause the greenhouse to collapse. Therefore, it is necessary to clean the snow on the fruit greenhouse. However, most of the snow cleaning in fruit greenhouses is done manually, so the snow cleaning work on fruit greenhouses is becoming more and more arduous. Utility Model Content
