Abstract

A pulley roll-up machine for the shed is an agricultural machinery. The rope fixed on the steel tube is turned backward by utilizing the pulley, and is winded through the motor and the worm wheel reducer, with the steel tube rotation reduced by more than 90% comparing with the prior art; the straw curtain of the sunlight green house shed is rolled up as driven by the rope.

Description

The pulley greenhouse curtain rolling machine

One, technical field:

The utility model is above the roll-top day-light greenhouse, the agricultural machinery of the straw screen or mat that is used to be incubated.

Two, background technology:

Prior art is the driven by motor worm reduction gear, is transferred to and isometric being fixed on the steel pipe on booth top with support of booth again, utilizes the rotation connection of steel pipe to be fixed on rope on the steel pipe.Straw screen or mat is rolled or covered down.This is a kind of locates more common (see figure 1) in Shouguang City, Shandong Province science and technology demonstration etc.Another kind is to be fixed on the V-type travel(l)ing rest with motor, worm reduction gear and with the isometric steel pipe of booth, utilizes steel pipe to rotate walking on booth, straw screen or mat is rolled or covered down (seeing patent ZL99247270.9 or accompanying drawing 2).

Three, summary of the invention:

The utility model institute's gas-distributing motor and worm reduction gear etc. are same as the prior art, the technical problem that it solved is: reduce materials such as the used steel pipe of prior art, axle, bearing, watt box more than 90%, the rope that utilizes pulley that the roll-top straw screen or mat is used leads on the steel pipe of booth length below 10%, make the stressed of steel pipe by becoming both direction to the left and right forward, along with (seeing Fig. 3, Fig. 4, Fig. 5) rolled straw screen or mat or cover down in the rotation of steel pipe.Beneficial effect: manufacturing of roller shutter machine and installation cost are reduced greatly, not only do not influence the quality and the speed of roll-top straw screen or mat, and alleviated the burden of motor, reductor and pillar, balance steel pipe stressed, steel pipe is not yielding, has reduced cost, the peasant easily accepts, and is easy to popularize.

Five, embodiment:

Following index map 3, Fig. 4, Fig. 5 explanation: with motor (1), worm reduction gear (2), steel pipe (3), axle, bearing is connected with a watt box (4) and is fixed on the steel pipe support (11), pulley (5) is fixed on the pulley bracket (6), with some ropes (7) (what of rope, decide according to booth length) end is fixed on the top of booth (10), and be tiled in above the booth (10), end with some straw screen or mat (8) also is fixed on booth (10) top then, and the whole booth of open and flat covering (10), the other end of straw screen or mat (8) is fixing with bamboo bar (9), it is become one, again with the other end of rope (7), after process pulley (5) turns to, strain and be vertically fixed on the steel pipe (3).The distance that 20-30cm will be arranged between the last every rope of steel pipe (3) (7) is in case twine mutually.Motor (1) but rotating, when just changeing, straw screen or mat (8) is rolled, on the contrary lid down.

Claims

1, pulley greenhouse curtain rolling machine and prior art are all finished volume amplification canopy straw screen or mat task by motor, worm reduction gear and steel pipe, the feature of pulley greenhouse curtain rolling machine is: motor, worm reduction gear, steel pipe, axle, bearing and a watt box are connected and are fixed on the steel pipe support, pulley is fixed on the pulley bracket, rope one end is fixed on the booth top, after the other end changes the direction of motion by pulley, link to each other with steel pipe, rope vertically is wound on the steel pipe, finish the task that volume is put straw screen or mat.

2, according to claim 1, the feature of pulley greenhouse curtain rolling machine is: as long as rope vertical with steel pipe, installed steel pipe in any case and all can after pulley turns to.

3, according to claim 1, the feature of pulley greenhouse curtain rolling machine is: vertical with steel pipe in order to make rope, the quantity of pulley and trend can change as required.
