Novel vegetable greenhouse fixing device

Abstract

The invention discloses a novel vegetable greenhouse fixing device and relates to the technical field of agriculture. A connection cross rod is fixedly arranged on the bottom sides of the upper ends of each two adjacent supporting frameworks through a connection device, the upper portion of each supporting framework is penetratingly arranged in clamping grooves formed in left and right side wallsof a U-shaped clamp, and each connection cross rod is penetratingly arranged at the bottom of the corresponding clamping groove vertically; a sliding groove is fixedly formed in the inner side wall ofthe U-shaped clamp, sliders are fixedly arranged on two sides of a clamping block and slidably arranged on the inner side of a sliding groove, a gasket is arranged above the clamping block and abutted against the bottom of each connection cross rod, a screw is rotatably arranged in the middle of the bottom side of the gasket through a bearing, the bottom end of the screw rotatably penetrates themiddle of the clamping block through a thread and then is fixedly connected with the middle of a thumb screw, and a plurality of fixing nails are fixedly arranged at the bottom of a base in an equal round corner manner. Stability among frameworks can be improved greatly, a greenhouse can be effectively prevented from being overturned when encountering strong wind, economic loss of a user is reduced, resources are protected, and the novel vegetable greenhouse fixing device is higher in practicability.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a novel vegetable greenhouse fixing device. Background technique [0002] Plastic greenhouse is a simple and practical protective cultivation facility. Plastic greenhouse makes full use of solar energy, has a certain heat preservation effect, and can adjust the temperature and humidity in the shed within a certain range through roll film; Less, with the development of the plastic industry, it is widely used by countries all over the world; using bamboo, steel and other materials, and covered with plastic film, to build an arched shed for the cultivation of vegetables, which can advance or delay the supply and increase the output per unit area. It is beneficial to defend against natural disasters; therefore, in the northern part of my country, plastic greenhouses mainly play the role of thermal insulation cultivation in advance of spring and late in autumn; In addition to over...

[0002] Plastic greenhouse is a simple and practical protective cultivation facility. Plastic greenhouse makes full use of solar energy, has a certain heat preservation effect, and can adjust the temperature and humidity in the shed within a certain range through roll film; Less, with the development of the plastic industry, it is widely used by countries all over the world; using bamboo, steel and other materials, and covered with plastic film, to build an arched shed for the cultivation of vegetables, which can advance or delay the supply and increase the output per unit area. It is beneficial to defend against natural disasters; therefore, in the northern part of my country, plastic greenhouses mainly play the role of thermal insulation cultivation in advance of spring and late in autumn; In addition to overwintering cultivation, the shading net can also be replaced for shading and cooling in summer and autumn, and rainproof, windproof, hailproof and other facility cultivation; the supporting framework of plastic greenhouses mostly adopts the supporting framework of steel pipe structure, and the framework in the prior art Generally, it is directly inserted into the soil and fixed. When encountering strong winds, the film paper on the greenhouse is easy to be lifted, and the skeleton is easy to deform, which will easily cause economic losses to users and waste resources. It needs to be improved urgently.
