Agricultural adjustable-overturn-type greenhouse cover structure for early maturing culture of vegetables

Abstract

The invention provides an agricultural adjustable-overturn-type greenhouse cover structure for early maturing culture of vegetables. The structure comprises top wedge-shaped blocks, locating blocks, bilateral clamping grooves, first top bracing plates, second top bracing plates, third top bracing plates, clamping groove installing plates, slide plates, a top pushing plate, motors and motor installing rods; three rail rods are arrayed at equal intervals, three slide grooves are formed in the middles of the three rail rods, and the three slide plates are slidably arranged in the three slide grooves; the second top bracing plates are rotatably connected with the back ends of the rail rods, and the first ends of the second top bracing plates are rotatably connected with the portions of three fifth length of the clamping groove installing plates; through the arrangement of the three top wedge-shaped blocks and three wedge-shaped pressing blocks, it is only required that top threaded rods are contrarotated and loosened, the three wedge-shaped blocks slide backward and are separated from the three wedge-shaped pressing blocks, transparent PVC cover plates lose locating, and therefore thetransparent PVC cover plate can be conveniently slidably drawn out for replacement after being damaged.

Description

technical field [0001] The invention belongs to the technical field of vegetable greenhouses and agricultural equipment, and more specifically relates to an adjustable flip-type shed structure for early-maturity cultivation of agricultural vegetables. Background technique [0002] The vegetable greenhouse is a frame-covered structure with excellent thermal insulation performance. It appears that people can eat off-season vegetables. Generally, the vegetable greenhouse uses a bamboo structure or a steel structure frame, covered with one or more layers of thermal insulation plastic film, thus forming a greenhouse space. The outer film can prevent the loss of carbon dioxide produced by the growth of vegetables inside, so that the shed has a good heat preservation effect. The top air vents of modern greenhouses are equipped with adjustable flip-type shed covers as standard. The existing sheds on the real surface The mechanical structure for flipping and closing the cover is rel...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above technical problems, the present invention provides an adjustable flip-type shed structure for early-maturity cultivation of agricultural vegetables to solve the problem that the existing shed cover has a relatively complicated mechanical structure for flipping and opening, which causes a high mechanical failure rate and is not easy to maintain. In addition, the light-transmitting cover is locked and integrated on the support frame of the canopy, and it is inconvenient to repair and replace after damage
