Hoisting slider device for insulating layer in greenhouse

Abstract

The invention discloses a hoisting slide device for an insulating layer in a greenhouse. The device provided by the invention comprises a frame, wherein a tackle capable of hoisting the insulating layer in the greenhouse is arranged below the frame; and the tackle is in slip connection with the frame. According the invention, a material steel angle which is never used in a greenhouse heat insulating object operation track design is utilized, so that products can be standardized more easily; the tackle is easy to develop and realize large-scale production; and the overall system is stable in operation, small in resistance, large in bearing, less possibility of digression and less possibilities of squeezing and torsion failure. Compared with the prior art, according to the invention, the cost for each common greenhouse can be saved about ** yuan, thus due to the change, a hanging-type inner heat insulating greenhouse has great popularization and application prospects.

Description

technical field [0001] The invention relates to a hoisting and sliding device for an insulating layer, in particular to a hoisting and sliding device for an inner insulating layer in a greenhouse, and belongs to the technical field of agricultural machinery. Background technique [0002] Internal thermal insulation solar greenhouse is a new type of greenhouse that has just emerged in the past few years. Its structure and various materials are being rapidly improved. As far as the opening and closing methods of the insulation layer are currently used, there are two types: laying type and hanging type. One, the former needs the inner skeleton for support, and the latter only needs the outer skeleton as the track. Obviously, the latter has great structural advantages and cost advantages. But the application of hanging type heat preservation is still only a few at present, and its track mainly still borrows curtain track to reform and use, does not have this track and supportin...

AI Technical Summary

Problems solved by technology

The price of the curtain track is very high, generally about 20 yuan per meter, and an ordinary greenhouse needs 24,000 yuan, which is expensive for agricultural greenhouses, which greatly reduces the possibility of application of this kind of greenhouse

[0003] We tried to make a kind of track suitable for heat preservation in the greenhouse. The available forms are: steel wire cable, steel plate, channel steel, I-beam, square steel pipe, etc. After comparison, we found that the cost of steel wire cable is low, but the operation is too Unstable and easy to derail; the steel plate is easy to deform after many days of operation, that is, the two sides are bent down, resulting in derailment; channel steel and I-beam are difficult to participate in the production of the arch skeleton; square steel pipes need to undergo secondary processing to open a seam to As a track material, it is more troublesome

[0004] Moreover, the suspender of the general block is fixedly connected to the main body of the block, and the frame has an arched curvature. The angle between the block and the track changes constantly during operation, so that it is easy to generate internal torsion inside the block or squeeze the track. These factors put forward higher requirements for the structure of the block itself and the coordination between the block and the track.
