A greenhouse with adjustable space size

Abstract

The invention relates to the technical field of agricultural greenhouses, and discloses a greenhouse with an adjustable space size. The greenhouse with an adjustable space size includes a movable block and a fixed rod, and a connecting hole is opened in the center of the two movable block bodies. A telescopic rod is fixedly connected to the bottom of the movable block, and a hinge is rotatably connected to the side of the two movable blocks close to the fixed rod. The greenhouse with adjustable space size, through the structural design of the rotating handle and the rotating gear, can facilitate the farmers to turn the rotating handle to make the rotating gear rotate, and then through the structural design of the transmission rod and the first conical gear, the rotating gear can drive the second The two bevel gears rotate so that the transmission gear can also rotate, and then through the structural design of the transmission gear and the semi-circular gear, the connecting rod can be rotated to a certain extent, so that the greenhouse with adjustable space size can be achieved without rebuilding The bracket serves the purpose of expanding the interior space.

Description

technical field [0001] The invention relates to the technical field of agricultural greenhouses, in particular to a greenhouse with adjustable space size. Background technique [0002] With the production of high molecular polymers - polyvinyl chloride and polyethylene, plastic films are widely used in agriculture. In the early 1950s, Japan and European and American countries successfully applied greenhouse films to cover hotbeds, and then covered small sheds and greenhouses with good results. , my country introduced polyvinyl chloride agricultural film in the autumn of 1955. It was first used in small sheds to cover vegetables in Beijing, and achieved the effect of early maturity and increased production. Greenhouses were originally special equipment for vegetable production. With the increasing popularity of greenhouses, farmers can use them even in winter. With the development of production, the application of greenhouses has become more and more extensive. At present, gree...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a greenhouse with an adjustable space size, which has the advantage of expanding the internal space without re-building the bracket, and solves the problem that the internal space of the existing greenhouse is fixed. When there is a need to expand or reduce the internal space of the greenhouse, the support needs to be removed and rebuilt, which increases the working hours of the farmers and the cost of the greenhouse support.
