Driving system for converting sunshade net and thermal screen for greenhouse

Abstract

The invention provides a driving system for converting a sunshade net and a thermal screen for a greenhouse. The driving system involves an active driving device, a main driving beam, a first drivingbeam, a second driving beam, hook disengagement and engagement devices and limiting devices, wherein the active driving device comprises a driving motor, a power coupling output reel, a driving rack and a push rod, and the driving motor is mounted on the power coupling output reel arranged on a greenhouse main beam on the first side; the first end of the push rod is slidably connected with slidingwheels arranged at the two ends of a greenhouse main beam located on the second side, and the driving rack at the second end of the push rod meshes with gears at the two ends of the power coupling output reel; and the two ends of the main driving beam are fixedly connected with the middle of the push rod, the first driving beam and the second driving beam are located on the two sides of the maindriving beam, the hook engagement and engagement devices are arranged on the main driving beam, and the limiting devices are fixed to the greenhouse main beams. According to the driving system, one oftwo sets of control systems can be alternately selected to be driven according to requirements, so that different action tasks are achieved, operation is stabler, and the failure rate is reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural facilities, and in particular relates to a driving system for switching between a sunshade net and a thermal insulation curtain for a greenhouse with single drive control and double systems. Background technique [0002] Through the analysis and comparison of a large number of greenhouse facilities, the internal heating and cooling facilities account for a considerable proportion of greenhouses, and they have a good effect on crops. Natural heating and cooling methods have become the first choice as an energy-saving strategy. In the greenhouse, the function of the sunshade net is to slow down or completely block the sunlight radiation to achieve the purpose of reducing the indoor temperature; the function of the thermal insulation screen is to isolate the natural convection heat exchange of the air to achieve the purpose of maintaining the indoor temperature. According to their seasonal use ...

AI Technical Summary

Problems solved by technology

Two sets of independent systems occupy two sets of relatively large driving mechanisms, which increases the weight of the top of the greenhouse, the shading rate is high, and the cost is several times higher
