Agricultural greenhouse support

Abstract

The invention relates to the technical field of agriculture, and discloses an agricultural greenhouse support which comprises an elastic supporting rod and a rectangular sleeve, the lower end of the elastic supporting rod is divided into two parts, a special-shaped sliding groove penetrating through the two ends of the rectangular sleeve is formed in the rectangular sleeve, a branch at the lower end of the elastic supporting rod is slidably clamped in the special-shaped sliding groove, and an arc-shaped frame is arranged at the lower end of the rectangular sleeve. The upper end of the arc-shaped frame is arranged in the special-shaped sliding groove in a sleeved mode, and an adsorption assembly is arranged on the outer wall of the arc-shaped frame. According to the device, the interior of the fixing sleeve can be in a negative pressure state, a plastic film is adsorbed, the plastic film can be rapidly fixed, the plastic film does not need to be perforated and bound, the greenhouse effect in a greenhouse is better, snow can smoothly slide down along an inclined plane, icing and shielding are prevented, and the device is convenient to use. And the plastic film can be prevented from being scraped.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to an agricultural greenhouse support. Background technique [0002] In agriculture, in order to allow crops to grow all year round, greenhouses are built. The current greenhouse framework is mainly fixed by arc-shaped metal tubular poles, which are arched and covered with plastic films. Simple Form agricultural greenhouses; [0003] But this design is not suitable for any place, for example, in the cold area of ​​Northeast China, the area where agricultural greenhouses are more sustainable, the winter is longer and the temperature is lower, so there are more rainy and snowy weather, in such an environment There will be a lot of snow accumulated on the agricultural greenhouses, as well as ice cubes formed by snow melting, which will not only easily crush the plastic on the greenhouses, but also easily block the sunlight, making the crops in the greenhouses in a cold state.

[0003] But this design is not suitable for any place, for example, in the cold area of ​​Northeast China, the area where agricultural greenhouses are more sustainable, the winter is longer and the temperature is lower, so there are more rainy and snowy weather, in such an environment There will be a lot of snow accumulated on the agricultural greenhouses, as well as ice cubes formed by snow melting, which will not only easily crush the plastic on the greenhouses, but also easily block the sunlight, making the crops in the greenhouses in a cold state. It is beneficial to the growth of crops, so it needs to be cleaned manually, and when the scope of the greenhouse is very large, it is difficult to operate. Here we propose an agricultural greenhouse support
