Description
Technical field
The utility model relates to the protector on a kind of roller shutter machine.
Background technology
Along with the agrotechnique progress, become main body in the current factory farming facility at the northern plastic green house of China, to be that agricultural obtains highly efficient and productive, the some effective of high-quality.Because winter, intensity of illumination was unfavorable for crop growth inadequately, therefore adopted the insulation measure of greenhouse rolling blind.The roller shutter machine has been installed on traditional plastic tunnel, and two surveys are provided with rolling bar about the roller shutter machine, and rolling bar supports with staking out, and rolling bar rolls in the cover of staking out, all be used for volume by a nylon rope pulling and put curtain on each rolling bar.In using when volume is put curtain, because operator's misoperation or the rope sling that has are when loosening, because of the operator breaks rules and regulations to operate under non-stop-machine situation; will be got involved in by rope; lived by rope strand, sometimes even can be in peril of one's life, so there is potential safety hazard in the roller shutter machine of this green house.
Summary of the invention
The utility model has overcome the defective of above-mentioned existence, and purpose is to be plastic greenhouse, and the protector on a kind of roller shutter machine is provided.
Protector content Description on the utility model roller shutter machine:
Protector on the utility model roller shutter machine; it is characterized in that: protector is a cut-off switch or combined floodgate switch; protector is fixed on the roller shutter machine host; protector is by safety rope and fastening stretching connection of the booth column at booth two ends; make extension spring be half arciform attitude, the height that steel wire tow line connects on the booth column is apart from volume thick stick lower end 35cm.
Safety rope is a steel wire tow line.
Protector on the utility model roller shutter machine is used for the roller shutter machine; it is the tight and personnel protection device of roller shutter machine; when the operator touches the safety rope of pulling roller shutter because of carelessness, the shutdown of can cutting off the power supply immediately of the protector on the roller shutter machine host, the generation of thoroughly having stopped potential safety hazard.
Description of drawings
