Foldable sunshade with controllable shading degree

Abstract

The invention relates to the field of agricultural conservation, in particular to a foldable sunshade with a controllable shading degree. The foldable sunshade with a controllable shading degree comprises a sunshade assembly, a supporting assembly and a blocking assembly. Shading stripes are uniformly distributed on conveyor belt type sunshade cloths in the sunshade assembly, and the shading degree is adjusted by adjusting the dislocation degree of upper and lower layer sunshade cloths. The supporting assembly is used for providing supporting for the sunshade assembly and providing a manual operation mechanism for folding and unfolding the sunshade assembly so as to avoid the situation that plants cannot be irrigated due to the fact that rainwater is intercepted by folding the sunshade assembly. The blocking assembly is used for providing assistance for the manual operation mechanism of the supporting assembly. When the sunshade assembly is lowered, the manual operation mechanism is not prone to being controlled due to gravity. The falling speed of the sunshade assembly is reduced through the action of the blocking assembly, so that the manual operation mechanism is easy to control. The device can meet the requirement of sunshade of plants, adjust shading degree and folding and unfolding state, and has simple structure and easy operation.

Description

technical field [0001] The invention relates to the field of agricultural maintenance, in particular to a retractable awning with controllable shading degree. Background technique [0002] The shading degree of ordinary awnings is non-adjustable, and its state is only light-transmitting and shading. However, awnings with light-transmitting adjustment functions generally have complex structures and high costs, and it is not necessary to strictly control the shading degree in consideration of conventional shading. Therefore, a low-cost awning with an adjustable shading degree that can meet the requirements of use is needed. In addition, considering the problem of rainwater supply, the awning cannot block the rainwater. Supply must be able to be retracted. Contents of the invention [0003] Aiming at the problems in the prior art, the present invention provides a retractable awning with controllable shading degree, which can meet the shading requirements of plants and can re...
