Movable skeleton for blueberry planting greenhouses

Abstract

The invention discloses a movable skeleton for blueberry planting greenhouses. The movable skeleton comprises a plurality of vertical support rods, L-shaped horizontal support rods and a slidable support device; rectangular platforms are arranged at both the upper and lower ends of the vertical support rods; the L-shaped horizontal support rods are fixed between the rectangular platforms at the upper ends of every two vertical support rods; the slidable support device comprises a plurality of symmetric support sliding blocks, support plates, first connection rods, second connection rods and arc-shaped support frames; convex sliding blocks are arranged on the support sliding blocks; the convex sliding blocks are glidingly arranged in a convex sliding chute; the support plates are arranged at the upper ends of the support sliding blocks; hinge seats are arranged on the support plates; the first connection rods and the second connection rods are respectively hinged with the hinge seats; the arc-shaped support frames are horizontally arranged on two symmetric support plates through bolts; and the adjacent first connection rod and the second connection rod on the same side are hinged with each other. The movable skeleton is simple to assemble, stable in structure and not easy to collapse.

Description

technical field [0001] The invention relates to the technical field of blueberry planting equipment, in particular to a movable frame for blueberry planting greenhouses. Background technique [0002] With the emergence of high molecular polymers - polyvinyl chloride and polyethylene, plastic films are widely used in agriculture. In the early 1950s, Japan, 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 to cover vegetables in small sheds in Beijing, and achieved the effect of early maturity and increased production. The greenhouse was originally a special equipment for vegetable production. With the development of production, the application of greenhouses has become more and more extensive. At present, greenhouses have been used for potted flower and cut flower cultivation...

AI Technical Summary

Problems solved by technology

[0003] The general greenhouses are built with bamboo poles, fixed with ropes, and then covered with film, but this structure is not stable enough, and it is easy to be blown down in the season of strong winds. For repeated use, a large amount of materials need to be prepared every year
