Automatic limiting protection device for greenhouse heat preservation roller shutter

Abstract

The invention relates to an automatic limiting protection device for a greenhouse heat preservation roller shutter, and belongs to the technical field of agricultural greenhouse mechanical equipment. The limiting protection device comprises an action obtaining mechanism, a triggering mechanism and a control mechanism, the action obtaining mechanism obtains the ascending / descending terminal action of the greenhouse heat preservation roller shutter, the triggering mechanism is connected with the action obtaining mechanism and moves along with the action obtaining mechanism to trigger the control mechanism, and the control mechanism is used for controlling stopping of the ascending / descending action of the greenhouse heat preservation roller shutter. The control mechanism comprises multiple controllers, the multiple controllers are sequentially arranged on the moving path of the trigger mechanism, and the trigger mechanism can continue to move to trigger the next controller after the previous controller fails until the ascending / descending action of the greenhouse heat preservation roller shutter is controlled to stop. According to the automatic limiting protection device for the greenhouse heat preservation roller shutter, multiple controllers are arranged, limiting protection work can still be continuously provided after the previous controller fails, and application is more reliable.

Description

Technical field [0001] The present invention involves the field of mechanical equipment technology in agricultural greenhouses, and specifically involves an automatic protection device for thermal insulation rolling curtain. Background technique [0002] With the continuous development of agricultural technology, more and more application of greenhouse greenhouses. In terms of greenhouses, temperatures are absolutely influential for greenhouses. Therefore, most of the northern regions with large temperature differences in day and night adopt the insulation curtain to keep the temperature in the shed in a relatively stable state. [0003] During the application of greenhouse greenhouses, some of them use artificially rolled greenhouse rolling curtains, with large workload and low degree of mechanization; some use simple mechanization to brake rolling curtains. The degree of the insulation curtain stretching rolls to prevent the motor from the end point command without limited stre...
