Automatic bidirectional winding and pulling device for sun protection and heat preservation of vegetable greenhouse

Abstract

The invention discloses an automatic bidirectional winding and pulling device for sun protection and heat preservation of a vegetable greenhouse, which comprises a greenhouse whole framework structure composed of a plurality of steel frames, winding frames are arranged at the two ends of the whole of the plurality of steel frames, a winding mechanism moving in the arc length direction of each winding frame is arranged on one side of each winding frame, each winding mechanism comprises a shifting motor for providing power and a pair of winding rods which are suspended above arc beams of the steel frames, can move synchronously with the shifting motor and can rotate, and a storage barrel is arranged at the top of one side of the whole of the plurality of steel frames in the direction of straight beams. The pair of winding rods is arranged above the greenhouse, sun protection and heat preservation cloth on the two sides of the greenhouse can wind around the winding rods at the same time, and the winding rods have popularization and practical value; and a storage barrel for storing the sun protection and heat preservation cloth is arranged on one side of the greenhouse steel frame, one end of the sun protection and heat preservation cloth is pulled out to wind around the winding rods through the motility of the winding mechanisms, then the sun protection and heat preservation cloth is moved to the other side of the greenhouse along with the winding mechanisms, and the top of the greenhouse is fully paved, so that the device is convenient and fast to operate, effort-saving and worry-saving.

Description

technical field [0001] The invention relates to the technical field of greenhouse planting, in particular to an automatic two-way rolling device for sun protection and heat preservation in vegetable greenhouses. Background technique [0002] At present, steel structure greenhouses are mostly used for growing vegetables in greenhouses, which are connected together by processed steel pipes and related accessories. Its construction cost is relatively high, but its service life is very long, and it is also convenient to replace the land and use it again. In winter, the greenhouse needs to be covered with insulation cloth for heat preservation, and in summer, it needs to be covered with sunscreen cloth to block direct sunlight. Generally, the motor is coaxially connected to a long shaft to wind the sunscreen insulation cloth. However, the top of the greenhouse is arc-shaped, which requires two sets of motors to be wound in half to cover the top of the greenhouse. The input cost ...

AI Technical Summary

Problems solved by technology

Generally, the motor is coaxially connected to a long shaft to wind the sunscreen and thermal insulation cloth. However, the top of the greenhouse is arc-shaped, which requires two sets of motors to be wound in half to cover the top of the greenhouse. The input cost is high. And if the sun-proof and heat-preserving cloth after winding is to be rolled out, people have to climb up to the top of the shed to pull out one end of the sun-proof and heat-preserving cloth, which is troublesome and inconvenient to operate; in addition, the long-term exposure of the motor to the sun and rain will affect its service life, which increases maintenance costs
