An arch shed ventilation device for agricultural planting and its application method

Abstract

The invention relates to an arch shed ventilation device for agricultural planting, which comprises an arch shed main body, the arch shed main body includes a plurality of arc-shaped support beams arranged side by side, and plastic cloth covers the arc-shaped support beams; the plastic cloth at the head end of the arch shed main body can be Partially opened to form the head vent, the plastic cloth at the end of the main body of the shed can be partly opened to form the tail vent, and the plastic cloth on both sides of the main body of the shed can be opened at intervals to form side vents. Through the reasonable structural configuration of the reduction motor, the first gear commutator, the second gear commutator and the square tube, it is connected with the side winding roller, the head winding roller and the tail winding roller, and combined with the first side ventilation The special winding and fixing methods of the pull rope, the second side ventilation pull rope, the head ventilation pull rope and the tail ventilation pull rope realize that the head ventilation port, the tail ventilation port and multiple side ventilation on both sides are driven by a geared motor The mouth opens and closes simultaneously. On the one hand, it saves the cost of equipment purchase, and on the other hand, it saves labor and time.

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
