Arched shed ventilation apparatus for agricultural planting, and use method thereof

Abstract

The invention relates to arched shed ventilation apparatus for agricultural planting. The arched shed ventilation apparatus for agricultural planting comprises an arched shed main body, wherein the arched shed main body comprises a plurality of arc-shaped support beams arranged side by side, a plastic cloth covers the plurality of arc-shaped support beams, the plastic cloth at the head-end of thearched shed main body can be partially opened to form a head-end vent, the plastic cloth at the tail-end of the arched shed main body can be partially opened to form the tail-end vent, and the plasticcloth on two sides of the arched shed main body can be opened at intervals to form side vents. The simultaneous opening and closing, driven by a geared motor, of the head-end vent, the tail-end vent,and the multiple side vents on two sides is realized through the reasonable structure configuration connection of the geared motor, a first gear commutator, a second gear commutator and a square tube, at the same time the cooperation of side winding rollers, a head-end winding roller and a tail-end winding roller, and the combination of a special winding and fixing manner of first side ventilation draw ropes, second side ventilation draw ropes, a head-end ventilation draw rope and a tail-end ventilation draw rope. On the one hand, the equipment purchase cost is saved, and on the other hand, the labor and time are saved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to an arch shed ventilation device for agricultural planting and a method for using the same. Background technique [0002] Arched sheds are generally made of bamboo poles and cement columns, with a lifespan of 3-10 years. The top is curved and covered with plastic film. Also called second shed, bread shed, cold shed. It is suitable for planting and breeding sheds in southern China and northern my country in spring, summer and autumn. Compared with greenhouses, arch sheds have lower thermal insulation performance. Second or third membranes can be added to the sheds to increase the night temperature. [0003] During the use of the arch shed, it is necessary to open the plastic sheets at both ends and both sides of the arch shed according to the temperature requirements of the vegetables in the shed for ventilation. The conventional method is to manually lift the plasti...

AI Technical Summary

Problems solved by technology

There are still many deficiencies in the use of the above-mentioned mechanical ventilation device: ① One set needs to be installed on both sides of the shed, resulting in high equipment purchase costs, and many farmers cannot accept the high equipment purchase costs; ② The coiling shaft rotates and coils The plastic sheeting is to open all the plastic sheets on both sides. For some vegetables that need ventilation on both sides, the above structure cannot meet the needs of use; ③The plastic sheets at both ends of the arch shed cannot be opened in conjunction with the plastic sheets on both sides, requiring additional manual open, time consuming
