Abstract

The utility model provides a curtain rolling up machine for sunlight greenhouses. A power is transmitted to a one-stage belt pulley and a three-stage gear reduction device through a forwards rotating and a backwards rotating motor output shafts. Then the output power is transmitted to a curtain rolling up shaft. A supporting base which is arranged on the upper end of a machine shell is fixed with a support rod. One end of the support rod is movably hinged with one end of a single armed rod with an angle, and the other end of the single armed rod is hinged with a supporting base shaft on a lower supporting base which is fixed on a foundation. A motor runs to drive the curtain rolling up shaft to rotate to roll up or lay down straw curtains to complete curtain rolling up automation for greenhouses. The utility model has the advantages of simple structure, convenient operation, time saving and labour saving, and being suitable for curtain rolling up automation of various greenhouse structures.

Description

Greenhouse by solar heat roller shutter machine

The utility model belongs to crops booth accessory device, particularly a kind of greenhouse by solar heat roller shutter machine.

Winter, the crops booth was warming, need to cover one deck straw screen or mat above, straw screen or mat is manual during daylight rolls, when night is cold straw screen or mat put down again and alternately finish the operating process that this is wasted time and energy, in order to solve this heavy and fall behind operation problem, at present, though a kind of roller shutter machinery occurred, but also will be subjected to the restriction of booth structure when mounted, install the back of need building a wall, and only can finish volume in the operation, also need artificial the cooperation when putting curtain, under canopy on the canopy, also twin shaft to be installed in addition, complexity be installed, the cost height, still it is time saving and energy saving to solve effectively, easy and simple to handle, cost is low, is not subjected to the problem of booth structure restriction.

The purpose of this utility model aims to provide a kind of in the installation of canopy front middle part, and the applied engineering mechanics lever principle, supports lifting by single armed, adapts to various booth structures, realizes the greenhouse by solar heat roller shutter machine of roller shutter automation, and is not enough to overcome in the prior art.

The novel purpose of this reality realizes with following technical scheme:

A kind of greenhouse by solar heat roller shutter machine, it is characterized in that, clockwise and anticlockwise motor is installed on casing, motor output shaft is given the one-level pulley decelerates with transmission of power, the one-level big belt pulley passes to the secondary plate gear with power by the toothed output major axis of terminal and slows down, the power of big plate gear passes to tertiary gear by band tooth minor axis and slows down, three grades of gear wheels are given the level Four gear reduction with transmission of power again, output shaft output with the level Four gear wheel, fixedly connected with curtain rolling shaft respectively in its output shaft two ends, curtain rolling shaft more respectively with booth on straw screen or mat one end fix, the straw screen or mat other end and ceiling are fixed, fixing upper bracket in addition in the casing upper end, be fixed with the upper bracket bar on the upper bracket, the termination that cradling piece has the angle of inclination becomes an activity point of view hinged with carriage bar one end, and the carriage bar other end is hinged with the bearing axle on the undersetting that is fixed on the ground.

Above-mentioned resultant gear ratio is 380: 1.

Above-mentioned upper bracket bar adds the long sum of carriage bar and equates with the distance that the greenhouse rolling blind arc length adds undersetting.

Characteristics of the present utility model are: can install at various canopy front middle parts, that can finish straw screen or mat rolls and puts down action, and time saving and energy saving, easy for installation, simple in structure, cost is low.

Below in conjunction with drawings and Examples in detail the utility model is described in detail:

Accompanying drawing 1 structural representation of the present utility model.

Accompanying drawing 2 the utility model support the A of lifting to schematic diagram.

Accompanying drawing 3 the utility model external structures.

Among the figure: 1 clockwise and anticlockwise motor, the large and small belt pulley of 2,3 one-levels, the large and small plate gear of 4,5 secondarys, 6,7 tertiary gears, 8,9 level Four gears, 10 output shafts, 11 curtain rolling shafts, 12 band tooth minor axises, 13 band tooth major axis, 14 upper brackets, 15 upper bracket bars, 16 carriage bar, 17 undersettings, 18 casings, 19 booths, 20 straw screen or mat.

As Fig. 1, at casing 18 sides three-phase 0.75KW clockwise and anticlockwise motor 1 is installed, motor 1 output shaft gives one-level big transmission of power, small belt pulley 2,3 slow down, terminal band tooth major axis 13 on the one-level big belt pulley 2 is given secondary big or small slice gear 4 in the casing with transmission of power, 5 slow down, three grades of pinions 6 and gear wheel 7 that band tooth minor axis outputting power on the big plate gear 4 passes on the band tooth major axis 13 slow down, three grades of gear wheels 7 slow down transmission of power again to the gear wheel 9 of the level Four pinion 8 on the same axle with its engagement, the overall ratio of output shaft 10 outputting powers at gear 9 two ends is 380: 1, its output shaft 10 two ends are fixedly connected with curtain rolling shaft 11 with flange respectively, curtain rolling shaft more respectively with booth 19 on straw screen or mat 20 1 ends fix, the straw screen or mat other end and ceiling are fixed.Fixing upper bracket 14 in addition in casing 18 upper ends, the upper bracket 14 upper bracket bar 15 that has been welded, it is hinged that upper bracket bar 15 has 16 one-tenth one activity point of view in termination and carriage bar at angle of inclination, carriage bar 16 other ends then with the undersetting 17 that is fixed on the ground on the bearing axle hinged, its cradling piece 15 adds ground undersetting 17 distances with long sum of carriage bar 16 bars and booth 19 roller shutter arc length and equates that its angle of inclination is set according to design angle is installed.

Operation principle: clockwise and anticlockwise motor 1 work of just changing a job, rotate with per minute 2 rotary speeds by level Four deceleration curtain rolling shaft 11, playing the upper bracket bar 15 of reacting force of supporting and the supporting motive force of carriage bar 16 when rolling by straw screen or mat makes straw screen or mat 20 steadily roll again, finish the greenhouse solar radiation of every day, when clockwise and anticlockwise motor 1 counter-rotating work, then steadily put down the invasion and attack of solution cold at night and high wind on the contrary according to straw screen or mat 20, winter protection is incubated again.
