Description

Sky is put cruise control formula greenhouse curtain rolling machine

Technical field

The utility model relates to a kind of roller shutter machine that is used for green house, particularly a kind ofly existing fixing box greenhouse curtain rolling machine is carried out improved sky puts cruise control formula greenhouse curtain rolling machine.

Background technology

At present, along with the development of chamber planting technology, the use of greenhouse curtain-rolling machine has obtained popularizing.Existing fixing box greenhouse curtain rolling machine great majority all put speed-controlling device, motor by cabinet, decelerator, self-locking device, hand brake device, sky and fall, institute such as clockwise switch forms.And sky is when putting, what all adopt is that manual sky is put the gliding speed that the fast mechanism of control controls the canopy curtain, the fast mechanism of this control had both involved sky and has let slip in the journey and must operate all the time with manpower, can't make the sky of canopy curtain put realization again at the uniform velocity glides, in case manually sky is put the fast mechanism of control when malfunctioning, and the accidents such as damage that the braked wheel self-destruction flies to wound the people and causes the booth affiliated facility very easily take place.

The utility model content

The purpose of this utility model provides a kind of sky and puts cruise control formula greenhouse curtain rolling machine, it has fundamentally solved the manual operation accident-prone defective out of control that existing fixing box greenhouse curtain rolling machine exists, have simple in structure, reasonable in design, when putting, sky need not manually to control the gliding speed of canopy curtain, advantage safe in utilization, reliable.

The purpose of this utility model is achieved in that this machine comprises cabinet, decelerator and self-locking device, hand brake device, sky of assembling in it are put speed-controlling device and drive unit, its technical essential is: described sky is put speed-controlling device and is adopted sky to put the cruise control device, the brake arm that sky is put the cruise control device directly is fixed on the output of the high speed shaft of decelerator, the braking hub is fixed on the axle bed of reducer shell of this high speed shaft output, and the control speed shoe plate, the fast piece of control that together rotate along with brake arm are assembled in the braking hub.

The hand-made driving wheel of described hand brake device is fixed on sky and puts on the brake arm of cruise control device, brake band is looped around on the hand-made driving wheel periphery, the brake band end utilizes bearing pin to be fixed on the support of cabinet, and by extension spring and handle location-plate that the brake handle of brake band end is spacing on support, make brake band break away from hand-made driving wheel periphery.

Because fundamentally having changed the sky of existing fixing box greenhouse curtain rolling machine, the utility model puts speed-controlling device, it is that sky is put the cruise control device that the sky that is adopted is put speed-controlling device, and the brake arm that sky is put the cruise control device directly is fixed on the output of the high speed shaft of decelerator, utilize simultaneously be assembled in the braking hub along with brake arm together the control speed shoe plate of high speed rotating and the brake force that the fast piece of control produces, automatically finish sky and put control speed, so it is simple in structure, reasonable in design, when putting, sky need not manually to control the gliding speed of canopy curtain, braking ability is stable, and sky to put speed even, safe in utilization, reliably.Let slip the brake handle of the brake band end that can also utilize hand brake device in the journey at sky, under the mating reaction of extension spring and handle location-plate, finish the work that breaks away from and hold hand-made driving wheel tightly, the normal volume of canopy curtain, the purpose of putting when speed-change and gearshift when the control sky is put braking and brakeless.

Embodiment

Describe the concrete structure of utility model in detail according to Fig. 1-5.This machine be on the architecture basics of existing fixing box greenhouse curtain rolling machine, carry out improved.It comprises that decelerator 1 and hand brake device, skies in cabinet 7, the assembling cabinet 7 put parts such as cruise control device 4, self-locking device 3 and drive unit.The specification of cabinet 7, decelerator 1, self-locking device 3 and drive unit wherein, the structure basically identical of shape and existing fixing box greenhouse curtain rolling machine.Drive unit comprises motor 6, bel-drivenn motor pulley 5 and power shaft belt pulley 2.Decelerator 1 adopts known configurations, it comprises the housing 16 on the support 28 that is fixed on cabinet 7, the power shaft (I) 12 that has power shaft belt pulley 2, change gear shaft (II) 11, change gear shaft (III) 10, output shaft (IV) 9 and be contained in this part such as Hooks coupling universal coupling 8 on 9, wherein change gear shaft (II) 11 outputs stretch out the axle bed of reducer shell 16, and support sealing with bearing 17 and sealing ring 18.

Sky is put speed-controlling device 4 and is adopted sky to put the cruise control device.It comprises braking hub 21, and brake arm 19 is controlled fast piece 15 and fast shoe plate 14 parts such as grade of control.Wherein brake arm 19 usefulness flat keys 20 directly are fixed on high speed shaft (the high speed shaft employing change gear shaft (II) 11 of present embodiment of decelerator 1, also can be fixed on as required on other high speed shaft) output, braking hub 21 is fixed on the axle bed of change gear shaft (II) 11 outputs of reducer shell 16.The control speed piece 15 and the fast shoe plate 14 of control that together rotate with brake arm 19 are assembled in the braking hub 21.The brake band 23 of hand brake device is looped around hand-made driving wheel 13 peripheries, and hand-made driving wheel 13 is fixed on sky by bolt 22 and puts on the brake arm 19 of cruise control device, and the axial float of fast shoe plate 14 of restriction control simultaneously and the fast piece 15 of control makes it do radial motion.Brake band 23 ends utilize bearing pin 24 to be fixed on the support 28 of cabinet 7, and by extension spring 26 and handle location-plate 29 that the brake handle 25 of brake band 23 ends is spacing on support 28, make brake band 23 disengagings or hold hand-made driving wheel 13 peripheries tightly.When sky was put, by propping of handle location-plate 29, let-down made the brake handle 25 of brake band 23 ends rotate around bearing pin 24, finishes the work that brake band 23 breaks away from and holds hand-made driving wheel 13 tightly.

When normal roller shutter was operated, hand was moved brake handle 25, with handle location-plate 29 spacing being supported on the support 28, made the periphery of system with the hand-made driving wheel 13 of 23 disengagings, did not produce braking effect.

When sky was put the operation of canopy curtain, first let-down handle location-plate 29 made brake handle 25 under extension spring 26 effects, drives brake band 23 and holds tightly on the periphery of hand-made driving wheel 13, produces braking effect.Handle the gear change hand lever of decelerator 1 then, make the transmission gear on the change gear shaft (II) 11 that is loaded in the decelerator 1 be in neutral position, handle location-plate 29 is supported on the support 28 again, can carry out sky and put the canopy curtain.At this moment, when change gear shaft (II) 11 glides at the canopy curtain, by reducer output shaft (IV) 9, the speed change of change gear shaft (III) 10 drives down, do high speed rotating, make the fast piece 15 of control under action of centrifugal force, compress the fast shoe plate 14 of control on the inwall of braking hub 21, make brake arm 19 rotations produce resistance, thereby the rotary speed of change gear shaft (II) 11 is reduced rapidly, the rotating speed that causes being transferred to reducer output shaft (IV) 9 also decreases, and reaches the purpose that the canopy curtain slowly, steadily, at the uniform velocity glides.
