Abstract
The utility model relates to a tool which used for rolling up straw mats in greenhouses. To solve the problems of complicated structure and operation inconvenience existing on an existing rolling apparatus, the utility model provides a rolling apparatus which is simple, handy and applicable. A pull rope is fixed on one side of a cross beam in a herringbone shape. Two arm ropes are respectively fixed on the left and the right ends of the other side of the cross beam. The other end of each of the arm ropes is movably connected with a rolling shaft through a bearing. The utility model has the advantages of simple structure, easy manufacture, easy operation, time saving and labor saving.
Description
The utility model relates to a kind of screen for hothouse device of mainly being made up of stay cord, crossbeam, curtain rolling shaft etc., specifically is used for the instrument of volume lifting straw screen or mat in the kind pipe greenhouse.
For kind of the peasant in pipe greenhouse, it is the work of wasting time and energy very much that every day volume is put straw screen or mat, and along with popularizing of greenhouse, this problem is also more outstanding.So produced the mechanization roller blind device, but its investment is big, expense is high, inapplicable for the little people of economic condition difference or planting greenhouse area.Disclose a kind of structure of screen for hothouse device in 1997 the 6th phases " the practical science and technology in rural area " that the Prairie Fire Program office of State Education Commission sponsors: rectangular empty framework is being fixed on the top of stay cord, the parts that link with stay cord are that crossbeam, relative edge are baffle plate for curtain rolling shaft, two ends, the left and right sides, one side shield is fixed, and a side shield is by tenon and the movable connection of mortise.During use, tenon inserts mortise, straw screen or mat is twisted in be pulled to ceiling on the curtain rolling shaft, and tenon and mortise are dismantled taken off screen-roller usefulness more again, though more time saving and energy saving than original method, this screen-roller complex structure, use trouble, be not easy to popularization.
The purpose of this utility model provides a kind of screen for hothouse device.This screen-roller is not only time saving and energy saving, and easy to operate, and is simple in structure, easy to manufacture, is easy to promote.
Concrete technical scheme of the present utility model is: this screen-roller mainly is made up of stay cord, crossbeam, curtain rolling shaft etc., wherein, stay cord is fixed on a side of crossbeam, and the two ends of the opposite side of crossbeam are fixed with two arm ropes, and the free-end of two arm ropes is associated with a bearing that matches with curtain rolling shaft respectively.
During use, two people cooperate, and a people twists in the straw screen or mat front end on the curtain rolling shaft in bottom, another people moves screen-roller to top at ceiling with stay cord, separates an end axle and a bearing, and curtain rolling shaft is extracted out from the straw screen or mat volume, assemble again, slide, repeat next operation along front roof.
For make bearing needn't be too big and straw screen or mat be easy to roll, the two ends of curtain rolling shaft can be narrower than the curtain rolling shaft main body and match with bearing on the arm rope.
In order to make curtain rolling shaft and bearing difficult drop-off when carrying straw screen or mat and scroll up, the curtain rolling shaft main body can be equal to or greater than the length of crossbeam.
Frictional resistance in using for reducing, crossbeam can link by iron hoop fixed thereon and stay cord and arm rope.
From structure of the present utility model its advantage and good effect as can be seen: this screen-roller is because simple in structure, not only make easily, whole light and handy, and spur laborsaving, repetitive operation convenient, very easily popularize.
Accompanying drawing is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with embodiment:
As shown in the figure: this screen-roller is made up of stay cord 1, crossbeam 2, curtain rolling shaft 3, stay cord 1 is the side that " people " font (also can be three fork-shapeds) is fixed on crossbeam 2, the two ends, the left and right sides of the opposite side of crossbeam 2 are fixed with two arm ropes 4, the other end of arm rope 4 is associated with bearing 5, and bearing 5 matches with the two ends of curtain rolling shaft 3.
During use, curtain rolling shaft 3 peaces are gone in the bearing 5, straw screen or mat is twisted on the curtain rolling shaft 3, upwards spur stay cord 1, straw screen or mat is rolled onto ceiling, pacify again to go in the bearing 5 after again curtain rolling shaft 3 being extracted out from bearing 5 and straw screen or mat, and glide, repeat next operation along front roof.
In addition, littler and make two arm ropes, 4 unlikely drawing close to the centre for making bearing 5 in order to avoid hang on the straw screen or mat, can make the two ends, the left and right sides of curtain rolling shaft 3 be narrower than curtain rolling shaft main body 6, and make its main body 6 be equal to or greater than the length of crossbeam 2.
Resistance when gliding along front roof for reducing screen-roller, crossbeam 2 can link by iron hoop fixed thereon 7 and stay cord 1 and arm rope 4.
For preventing screen-roller damage plastic greenhouse film, the two ends of crossbeam 2, curtain rolling shaft 3 are first-class all should be bright and clean, slick and sly.
