Description

Technical Field

[0001] The utility model relates to the technical field of greenhouses, and more specifically, to an adjustable cherry greenhouse roof structure. Background Art

[0002] Cherries are a cultivated variety of European sweet cherries, specifically referring to large, thick-skinned cherries produced in the Americas, such as the United States, Canada, and Chile. Cherries are one of the earliest tree fruits to be marketed, and are deciduous shrub fruit trees known as the "first branch of a hundred fruits." Cherries are mostly dark red, but also red and yellow, with a larger diameter. Fresh cherries are harder and have longer stalks.

[0003] Generally, cherries grow inside greenhouses, but the existing greenhouse roofs are mostly fixed and cannot be adjusted accordingly according to the changes in the spacing of the bottom supports, resulting in a narrow range of applications. Based on this, the utility model designs an adjustable cherry greenhouse roof structure to solve the above problems. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides an adjustable cherry greenhouse roof structure, which has the advantage of a wide range of uses.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an adjustable cherry greenhouse roof structure, comprising two bottom support assemblies mounted on the ground, a greenhouse roof assembly being detachably mounted on the top of the two bottom support assemblies, and the bottom support assemblies being used to support the greenhouse roof assembly;

[0006] The bottom support assembly includes a support guardrail, and a plurality of threaded columns distributed in a straight line are fixedly installed on the top of the support guardrail;

[0007] The greenhouse roof assembly includes two symmetrically distributed horizontal connecting tubes, a fixed horizontal plate 1 is fixedly installed between the two horizontal connecting tubes, the fixed horizontal plate 1 is located in the middle position of the horizontal connecting tube, and a telescopic plate is plugged into both ends of the horizontal connecting tube.
