Description

A kind of greenhouse curtain rolling machine

The utility model relates to stretching of plastic tunnel heat holding curtain and rolls up machinery.It exactly is a kind of greenhouse curtain rolling machine.

Along with the adjustment of the structure of agricultural production, all parts of the country utilize the people of plastic greenhouse cultivation vegetables, flowers and trees more and more.But, pendulum in the previous important problem of people's face is exactly, according to the morning and evening of time and the height of temperature, to constantly roll and stretch out the insulation straw screen or mat that covers the booth top, go round and begin again, careless slightly, straw screen or mat will be pulled apart or staved or askew heresy, directly influence service life, heat insulation effect and the income of heat holding curtain.At present, it is by manually utilizing cotton rope to connect the heat holding curtain bottom of booth sunny side that traditional heat holding curtain is stretched volume mode one, pulls at the back of booth and draws.This mode, time-consuming, easily cotton rope to be broken or heat holding curtain is torn, coverage effect is also bad, directly influences the insulation and the service life of booth.Another kind of mode is that mechanical type is stretched volume, promptly at the cloudy back side of booth, length scale according to booth does not wait, set up several supports, and these supports are coupled together by a metallic rod in the appropriate location that exceeds booth, (connecting portion employing shaft type) is provided with gear and 3kw-4kw three phase electric machine then and stretches the backguy rope on the support in canopy centre position, the pulling heat holding curtain is stretched volume.The drawback of this mode is that the support use is many, consumptive material is big, and is inconvenient by dress, and the three-phase electricity power source uses limitation big, power consumption is many, the cotton rope discontinuity, stretches to draw stressed greatly, and service life is short, about 7000 yuan every, the marketing benefit is low, uses restricted approximately for the cost height.

The utility model provides a kind of mechanical type, adopt two-phase or three phase mains, low, the low consumptive material of power consumption, long service life, by adorning greenhouse curtain rolling machine easily.

A kind of greenhouse curtain rolling machine is made up of electromotor, reductor, travel(l)ing rest, terminal pad, curtain rolling pole, auxiliary rope.Be characterized in that a travel(l)ing rest is set up at 1 meter-1.5 meters of spacing booth in the booth sunny side, base fixes on the ground with cement, support is connected with the heel pin shaft type, the height of support can be decided according to the height of booth, connect a motion bar at the top of support shaft type, it is consistent that the length of its motion bar and support stretching, extension and the width of booth add 1-2 rice.The other end of motion bar is connected with fixed screw with reductor, and its motion bar is used for connecting and supports reductor and motor and is its slide down action guiding.

One pinion is housed on the output shaft of reductor, at reductor wing-rooms on either side of a one-story house plate lengthening, a driven axle is housed, driven axle is adorned a gear wheel, makes it and the output shaft pinion, and the driven axle two ends are stretched out and linked to each other with curtain rolling pole.

Two phase-plates add that the driven axle that stretches out is connected on curtain rolling pole and the reductor, and parallel with booth, and its length is with identical with the length of booth, and (available as required flange connects), its adopts galvanized pipe or stainless steel tube to make.Weld a fixed claw every 0.5 meter on the surface of curtain rolling pole, when curtain rolling pole rotated, each fixed claw stretched into and catches straw screen or mat, made it to rotate with curtain rolling pole.Straw screen or mat is rolled immediately.

An auxiliary nylon cotton rope is placed every 2-3 rice position in bottom at straw screen or mat.One end of cotton rope ties up on the curtain rolling pole, and the other end is fixed on the upper end of booth north wall.Its objective is to stretch to lick in the journey that the direct tension that reduces straw screen or mat prolongs the service life of straw screen or mat at straw screen or mat.When connecting 20V or 380V power supply, (1.5kw or 0.75kw) reductor turns round under electrodynamic effect, drives curtain rolling pole and rotates, and the grip of the fixed claw of straw screen or mat on curtain rolling pole and the effect of auxiliary cotton rope convergent force are down auxiliary, finish straw screen or mat and roll task.This machine is simple in structure, and is easy for installation, and cost is low easily to be promoted.

Specify enforcement of the present utility model below in conjunction with accompanying drawing.

Fig. 1 is the utility model overall structure schematic diagram

Fig. 2 is an A-A B-B phantom shown in Figure 3

Fig. 3 is the utility model result of use figure

A kind of greenhouse curtain rolling machine is by electromotor 1 as shown in Figure 1, reductor 2, and travel(l)ing rest 3, terminal pad 4, curtain rolling pole 5, auxiliary cotton rope 6 is formed.Travel(l)ing rest 3 is installed in the booth sunny side and apart from booth 1-2 rice, it adopts stainless steel material to make, and its end is fixed on the ground the other end by base, link to each other with motion bar 17 shaft types as shown in Figure 3, it is identical that the length that motion bar 17 and support 3 stretches and the width of booth add 1-2 rice.As shown in Figure 3, the other end of motion bar 17 adopts screw to be connected with reductor 2, its objective is that supporting reductor also leads for it moves up and down.

Shown in Fig. 2 A-A portion, the output shaft 8 of reductor is provided with a pinion 11, at reductor wing-rooms on either side of a one-story house plate lengthening, a driven axle is housed, and its driven axle is installed a gear wheel 12, and meshes with pinion 11.As shown in Figure 1, reductor driven axle two ends are stretched out and are linked to each other with curtain rolling pole 5, and the length of curtain rolling pole is identical with the length of booth, and can increase and its length of employing flange connection increase on curtain rolling pole according to booth length.Curtain rolling pole adopts galvanized pipe or stainless steel tube to make.When the stressed rotation of curtain rolling pole, each fixed claw 18 stretches into and catches straw screen or mat, makes it to rotate with curtain rolling pole.Thereby roll straw screen or mat.

An end of placing auxiliary nylon rope 6 ropes every 2-3 rice position in the bottom of booth ties up on the curtain rolling pole 5 as shown in Figure 1, and the other end is fixed on the upper end of booth north wall.Its objective is to stretch and lick in the journey at straw screen or mat, reduce the direct tension of straw screen or mat, prolong its service life, (220V-380V after connecting power supply, 1.5w-0.75kw) reductor 2 turns round under electrodynamic effect, drive curtain rolling pole 5 and rotate, assisting down of the grip of the fixed claw 18 of straw screen or mat on curtain rolling pole and 6 contractions of auxiliary cotton rope finished straw screen or mat and rolled task.
