Description

The manual roller shutter machine of booth

Technical field

The utility model relates to a kind of greenhouse curtain rolling machine, relates to the manual roller shutter machine that a kind of plastic tunnel uses specifically.

Background technology

In order to improve the temperature of booth, general woven straw or other thermal insulation quilt of covering above the booth is owing to woven straw weight is heavier, folding and unfolding is very inconvenient, and insulation and light transmission are relatively poor, therefore in recent years, occurred that some are in light weight, heat-insulating property is thermal insulation quilt preferably.In order to solve the bigger difficult problem of the folding and unfolding amount of labour, various roller shutter machines have appearred, and the roller shutter machine that has is manual operations, and what have is electric operating.Most roller shutter machine structure more complicated, weight is heavier, drives roller shutter with chain or stay cord, and accidents happened easily during the roller shutter machine operation that has, and safety coefficient is low.

The utility model content

It is a kind of simple in structure that the purpose of this utility model provides, and weight is lighter, and is easy and simple to handle, the manual roller shutter machine of the booth that security performance is good.

For achieving the above object, the technical solution of the utility model is: the manual roller shutter machine of booth, described roller shutter machine comprises frame, manual driving device, decelerator, curtain rolling shaft, described manual driving device, decelerator are fixed on the frame, described curtain rolling shaft is fixedlyed connected with the output of decelerator, described drive unit drives curtain rolling shaft by decelerator and rotates, it is characterized in that: described curtain rolling shaft is a major axis, described roller shutter facility have running gear, described roller shutter machine is positioned at booth one end, and described roller shutter machine and curtain rolling shaft move up and down along booth with the roller shutter of scrolling.

The utility model adopts said structure, described roller shutter machine is arranged at booth one end, described curtain rolling shaft is a major axis, described roller shutter machine is mainly used in the lighter thermal insulation quilt of weight, whole thermal insulation quilt is fixed on the curtain rolling shaft, and described roller shutter facility have running gear, can guarantee that therefore described roller shutter machine and curtain rolling shaft move up and down along booth with the roller shutter of scrolling, and simple in structure, weight is lighter.

Improve as another kind, described manual driving device comprises driving wheel, and the hand crank that is connected with driving wheel with the driven pulley that the decelerator input is connected, is provided with transmission device between described driving wheel and the driven pulley.

Shake hand crank, driving wheel drives driven pulley, and driven pulley drives reducer shaft, and decelerator drives curtain rolling shaft, just can carry out the roller shutter operation.

Improve as another kind, described driving wheel and driven pulley are gear, and described transmission device is a chain gearing.

Improve as another kind, described running gear comprises roller shutter machine road wheel and the drawbar of fixedlying connected with the roller shutter machine, and described drawbar is consistent with roller shutter machine direction of travel, and described drawbar is provided with hauling rod wheel.

Drawbar and tugboat setting can guarantee that the roller shutter machine moves up and down along booth, and hauling rod wheel, road wheel and roller shutter guarantee the normal walking of roller shutter.

Improve as another kind, described curtain rolling shaft is thicker near roller shutter machine part.

Improve as another kind, described frame is provided with handrail.

Improve as another kind, described running gear comprises pulley and slide rail.

The utility model adopts said structure, because the utility model body itself only uses frame, transmission device and decelerator, so weight is lighter, very easy to use, the utility model is mainly used in the lighter thermal insulation quilt of weight, security performance is higher, the intensity of curtain rolling shaft when curtain rolling shaft more slightly can guarantee roller shutter near roller shutter machine part, be unlikely to fracture, frame is provided with handrail, and the another hand can held up handrail when shaking hand crank, conveniently shake hand crank, running gear can also be pulley and slide rail, guarantees that better the roller shutter machine moves up and down along booth, and whole system is simple in structure, very laborsaving, easy and simple to handle, the safety coefficient height has market using value preferably.
