Greenhouse structure with conveniently replaceable greenhouse film

Abstract

The invention provides a greenhouse structure with conveniently replaceable greenhouse film, which comprises a rectangular frame, an unwinding unit, greenhouse frame units, a fixing unit, a guide roller, a clamping block and a winding unit. The invention helps solve the problems that, for instance, most existing greenhouse films that are in roll form are replaced by being manually unfolded and laid on a greenhouse frame, the greenhouse films are perforated and are fixed on the greenhouse frame through ropes, and perforating the greenhouse films helps reduce the heat insulation performance of the greenhouse films and reduce their capacities to bear wind drag; the heights of the greenhouses are different according to different requirements for planting crops, and it is difficult to cover some greenhouses with great heights manually with the greenhouse films on the greenhouse frames, so that manual replacement of the greenhouse films is difficult.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a greenhouse structure which is convenient for replacing the greenhouse film. Background technique [0002] Greenhouse film is a special plastic film used for agricultural production and construction. Its light transmittance, heat preservation, tensile and aging resistance are better than ordinary agricultural film. It is of great significance to the growth of greenhouse crops, increasing production and increasing income. However, the greenhouse film has a certain service life. After reaching a certain service life, its light transmittance becomes low, and it is easy to cause damage and affect the temperature in the shed, resulting in a decrease in the growth rate of the plants in the shed. Therefore, the greenhouse film needs to be replaced regularly. . [0003] However, most of the existing greenhouse membrane replacements are manually unfolding and laying the...

Problems solved by technology

However, the greenhouse film has a certain service life. After reaching a certain service life, its light transmittance becomes low, and it is easy to cause damage and affect the temperature in the shed, resulting in a decrease in the growth rate of the plants in the shed. Therefore, the greenhouse film needs to be replaced regularly.

[0003] However, most of the existing greenhouse membrane replacements are manually unfolding and laying the rolled greenhouse membrane on the scaffold; punching holes in the greenhouse membrane and fixing it on the scaffold with ropes, the perforation of the greenhouse membrane reduces the thermal insulation performance of the greenhouse membrane , and reduce its ability to withstand wind resistance; and the height of the greenhouse is also different for different planting crops. For some high-height greenhouses, it is difficult to manually cover the greenhouse film on the scaffold, making it difficult to quickly replace the greenhouse film manually.
