Abstract

The utility model provides a kind of telescopic shutter, include booth, electromotor, roll bar, control head, expansion link, it is characterized in that: the ground of booth side is equipped with two fixtures, fixture is connected with one end of expansion link by articulated elements, the other end of expansion link is by being connected with electromotor, the other end of electromotor is connected with control head, connected by roll bar between two control heads, establish at booth top and a stop is housed, roll bar and thermal insulation quilt touching stop rear motor power themselves down.Advantage of the present utility model and good effect are: structure is simple, reasonable in design, make rely on roll bar and thermal insulation quilt self gravitation when launching thermal insulation quilt and do not need electromotor work, not only simple operation, can also economize energy; Electromotor is as individual components, and convenient disassembly, is convenient to safeguard and change, easy to manufacture and use.

Description

Telescopic shutter
Technical field
The utility model belongs to a kind of agricultural machinery, particularly relates to a kind of for the telescopic shutter of plastic greenhouse.
Background technology
Plastic greenhouse has obtained in rural area and has applied widely, has greatly promoted the development of rural economy, for
The growths of applicable crops in plastic greenhouse, temperature and humidity in booth all needs regularly to adjust, so some green houses in the winter time at night time, in order to be incubated, usually need thermal insulation quilt to be covered on booth ceiling, play necessary thermal insulation function, and to daytime, thermal insulation quilt is needed again to roll, the film of booth is allowed to be under the sun shines, carry out warming and heat insulation, traditional thermal insulation quilt adopts manually to be rolled, labour intensity is large, operating efficiency is low, although some place also uses some hand toolss or electric tool to roll up thermal insulation quilt, but can not synchronously roll whole thermal insulation quilt owing to designing unreasonable causing, so still convenient not, inadequate convenient power-saving, sometimes the thermal insulation quilt rolled comes irregular, not straight, also need to press with rope or draw, particularly for large-scale canopy, people are needed to go piecemeal to roll up thermal insulation quilt, waste time and energy, efficiency is low.
Summary of the invention
The utility model provides a kind of easy to use, the telescopic greenhouse insulation quilt shutter that can significantly raise the efficiency for solving in known technology the technical problem that exists.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
A kind of telescopic shutter, include booth, electromotor, roll bar, control head, expansion link, it is characterized in that: the ground of booth side is equipped with two fixtures, fixture is connected with one end of expansion link by articulated elements, the other end of expansion link is by being connected with electromotor, and the other end of electromotor is connected with control head, is connected between two control heads by roll bar, establish at booth top and a stop is housed, roll bar and thermal insulation quilt touching stop rear motor power themselves down.
Advantage of the present utility model and good effect are: structure is simple, reasonable in design, make rely on roll bar and thermal insulation quilt self gravitation when launching thermal insulation quilt and do not need electromotor work, not only simple operation, can also economize energy; Electromotor is as individual components, and convenient disassembly, is convenient to safeguard and change, easy to manufacture and use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, electromotor, 2, roll bar, 3, control head, 4, stopper slot, 5, expansion link, 6, fixture, 7, thermal insulation quilt, 8, stop.
Embodiment
For summary of the invention of the present utility model, Characteristic can be understood further, exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As shown in Figure 1: a kind of telescopic shutter, include booth, electromotor 1, roll bar 2, control head 3, expansion link 5, it is characterized in that: the ground of booth side is equipped with two fixtures 6, fixture is connected by articulated elements one end with expansion link 5, the other end of expansion link is by being connected with electromotor 1, the other end of electromotor is connected with control head 3, connected by roll bar 2 between two control heads, establish at booth top and a stop 8 is housed, roll bar and thermal insulation quilt 7 touch stop rear motor power themselves down.
Utility model works principle is: when green house needs volume thermal insulation quilt, electromotor l starts, electromotor by transmission of power to control head 3, control head 3 drives roll bar 2, thermal insulation quilt 7 on green house is wound in roll bar 2 after rotating by roll bar 2, electromotor l also promotes along large ceiling simultaneously, and elongate expansion link, now expansion link damping is less, until ceiling top, touching stop 8, automatic controller sends the signal of telecommunication, electromotor l is stopped operating, the thermal insulation quilt 7 of booth all can be rolled like this; When green house needs insulation, control head decontrols roll bar 2, roll bar 2 rotates backward under gravity, simultaneous retractable bar 5 is constantly compressed, because expansion link is larger by damping during compression, roll bar uniform speed slow can be made to decline, and the thermal insulation quilt in roll bar covers on booth ceiling again, and works without the need to electromotor 1.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
