The invention provides a drive system for switching between a sunshade net and a thermal insulation curtain for a greenhouse, which includes an active drive device, a main drive beam, a first drive beam, a second drive beam, a hook clutch device and a limit device, and the active drive device includes a drive Motor, power coupling output reel, driving rack and push rod, the driving motor is installed on the power coupling output reel arranged on the first side of the greenhouse main beam; The pulley provided at the end can be slidably connected, the drive rack at the second end of the push rod meshes with the gears at both ends of the power coupling output reel; the two ends of the main drive beam are fixedly connected with the middle position of the push rod, the first drive beam and the second drive The beam is located on both sides of the main driving beam, the hook clutch device is arranged on the main driving beam, and the limit device is fixed on the main beam of the greenhouse. The invention can alternately select and drive one of the two sets of control systems according to requirements, realize different action tasks, run more stably, and reduce failure rate.
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 ...
