AUTOMATIC FULLY-OPEN ROOF SYSTEM OF MULTI-SPAN SOFT-COVERED GREENHOUSE}

The present invention relates to an interlocking vinyl greenhouse, and relates to a roof automatic complete opening and closing system of an interlocking vinyl greenhouse that can automatically open and close the entire vinyl by adjusting the tension of the support band surrounding the roof vinyl.

In general, vinyl greenhouses should be able to produce crops of good quality by cultivating crops in optimal conditions by freely controlling the temperature, humidity, and light inside.

The general vinyl greenhouse currently installed is well shown in FIG. 1, and as shown, a typical vinyl greenhouse is provided with a plurality of arcuate frames (1) covered with a roof vinyl (2a) and continuously installed at equal intervals. It has a roof (2) made of a support band (3) which is installed at equal intervals on the upper part of the vinyl (2a) to surround and fix the roof vinyl (2a).

The lower end of the roof vinyl 2a is fixed to the lower part of the roof 2, and the roof vinyl 2a is wound while being rotated by the rotation driving force of the winding motor M1 provided on one side, thereby opening and closing the roof 2. While winding the air (5) is installed to circulate the indoor air to the outside.

At this time, the winding rod (5) is installed inside the support band (3) so as to wind the roof vinyl (2a), and opens and closes the roof (2) while lifting due to the winding force generated during winding. .

Of course, the winding rod (5) is self-rotating due to the drive of the winding motor (M1), thereby winding the roof vinyl (2a), and ascends along the roof vinyl (2a) by this winding operation In addition, the fall is prevented by the suspension action due to the wound roof vinyl 2a.

However, it is possible to prevent the fall of the winding rod 6 by installing the rotary link 6 as shown at both ends of the winding rod 5, it is also possible to smoothly guide the lifting.

On the other hand, the vinyl greenhouse is configured as at least one consecutively installed as shown is called the interlocking vinyl greenhouse, the interlocking vinyl greenhouse is installed side by side facing each other side of the roof (2).

Thus, rain gutters 4 for draining rainwater are installed in the valleys V between the roofs 2 facing each other.

 However, in such a general vinyl greenhouse, as the support band 3 pressurizes the outer circumferential surface of the winding rod 5, the winding rod 5 does not elevate to the upper end of the roof 2, and opens and closes only a part of the lower end of the roof 2. The opening and closing height (h) of the roof 2 opened and closed is only about 1 m, so that the indoor air of the vinyl house is not circulated in all but only part of the roof is circulated.

In addition, as the roof vinyl 2a wound on the winding rod 5 is damaged due to an increase in friction with the support band 3 pressed from the outside, the roof vinyl 2a needs to be discarded and replaced with a new one. There is also a frequent problem.

In addition, as the winding motor (M1) is provided on one side of the winding rod (5), the rotational driving force transmitted to both ends of the winding rod (5) is transmitted differently, so that the winding rod (5) close to the winding motor (M1) While the end rotates smoothly, the opposite end rotates less than this, so that both ends of the take-up rod 5 are lifted to different heights. Thus, a height difference occurs at both ends of the take-up rod 5, so that the roof vinyl 2a As well as being wound up inclinedly, there is also a problem that the winding rod 5 is bent.

The present invention was created in order to solve the conventional problems as described above, it is possible to automatically adjust the tension of the support band for supporting the roof vinyl of the interlocking vinyl greenhouse to prevent the support band to press the winding rod during the winding of the winding rod In addition, the winding rod can be lifted to the top of the roof to open and close the entire roof, and the roof of the interlocking vinyl greenhouse can be lifted up and down while winding the roof vinyl in a horizontal state by raising and lowering the same circumference at both ends. The purpose is to provide a fully open and closed system.

In the roof automatic complete opening and closing system of the interlocking vinyl greenhouse according to the present invention for achieving the above object, the plurality of support bands (3) at the same interval from the outside of the roof vinyl (2a) covered on the plurality of arcuate frame (1) In the interlocking vinyl greenhouse having a plurality of vinyl greenhouses having a tunnel-shaped roof (2) wrapped and facing each other roof 2 side, the arch-shaped frame (1) in the longitudinal direction of the roof (2) A mounting block 100 installed on the roof vinyl 2a and the upper end of the support band 3; The lower end of the roof vinyl 2a is fixed to the lower end fixing part 212 of the outer circumference and rotated by the driving force of the winding motor M1 provided integrally, while lifting and lowering the roof vinyl 2a to lift the roof. (2) winding rod 210 to open and close; Winding rod horizontal holding means (300) installed at both ends of the winding rod (210) to maintain the horizontal while inducing the lifting of the winding rod (210); Band tension adjusting means 400 for restraining a portion of the support band 3 to adjust the tension of the support band 3 while selectively pulling or releasing the support band 3 in accordance with the winding operation of the winding rod 210. It characterized in that it includes;

Hereinafter, with reference to the accompanying drawings will be described the automatic roof opening and closing system of the interlocking vinyl greenhouse according to the present invention as follows, in the description will be described with the same reference numerals for the components having the same technical idea as the prior art. .

And, Figure 5 is a side cross-sectional view showing the configuration of the mounting block and the winding rod shown in Figure 2, Figure 6 is a front view showing the eccentric disc pulley shown in Figure 2, Figure 7 is the eccentric disc shown in Figure 6 Figure 8 is a perspective view of the pulley, Figure 8 is a conceptual diagram showing the operating concept of the eccentric disc pulley shown in FIG.

As shown in the roof automatic complete opening and closing system of the interlocking vinyl greenhouse according to the present invention, a plurality of support bands 3 are equally spaced from the outside of the roof vinyl 2a covered by a plurality of arcuate frames 1 continuously installed rearward. It consists of a plurality of vinyl greenhouses having a tunnel-shaped roof (2) fixed to wrap, these vinyl greenhouses are installed in succession while facing each other the roof (2) side.

A valley V is formed between the facing roofs 2, and a rain gutter 4 is provided in the valley V.

At this time, in the present invention, the mounting block 100 for fixing the upper end of the roof vinyl (2a) and the support band (3) on the arch frame (1) was fixedly installed in the longitudinal direction of the roof (2), mounting The block 100 may be fixed to the arch frame 1 using the clamp 101 shown in FIG. 5, or may be fixed by welding the arc frame 1 and the mounting block 100.

The roof vinyl 2a fixed to the mounting block 100 is configured such that the upper end is fixed to both sides of the lower mounting block 100 by vinyl fixing means, and the support band 3 fixed to the mounting block 100. In the case, the upper end portion is fixed to the upper both sides of the mounting block 100 by the band fixing means.

Herein, the vinyl fixing means and the band fixing means will be described in detail with reference to FIG. 5. First, the vinyl fixing means has the insertion grooves 110 formed on both sides of the lower portion of the mounting block 100 in the longitudinal direction, thereby forming the roof vinyl 2a. Insert the upper end of the insert groove cover 112 is formed to be inserted into the insertion groove 110 into the insertion groove 110 by fastening the mounting block 100 with the fastening member 114, roof vinyl (2a) was configured to be pressed and fixed by the insertion groove cover 112.

At this time, the upper end of the roof vinyl (2a) should be inserted into the insertion groove 110 so as to project to the upper side of the mounting block 100, the insertion groove cover 112 is the roof vinyl (2a) in a zigzag manner (zigzag) For example, it is preferable to extend at least one rib R as shown in the longitudinal direction of the inner side so as to be fixed in a fixed manner.

Of course, the rib (R) is most preferably formed in the upper, lower and center of the insertion groove cover 112, in this case, the rib (R) formed in the center should be formed to be inserted into the insertion groove (110), Ribs (R) formed on the upper and lower ends of the insertion groove cover 112 should be formed to press the outside of the insertion groove (110).

If the rib (R) formed on the upper and lower ends of the insertion groove cover 112 to press the outside of the insertion groove 110 more firmly, the receiving groove or jaw that accommodates the upper and lower ribs (R). It may be formed on both sides of the mounting block 100.

Therefore, the roof vinyl 2a is integrally fixed to the mounting block 100 by the insertion groove 110, the insertion groove cover 112, and the fastening member 114.

Next, the band fixing means forms a locking protrusion 122 at the upper end of the support band 3, and forms an open protrusion insertion groove 122 having one side into which the locking protrusion 122 is inserted at both upper sides of the mounting block 100. As such, the locking protrusion 122 is inserted into the protrusion insertion groove 120 to be caught and fixed.

At this time, since the support band (3) is made of a plurality of as shown in Figure 2 by inserting in a manner to be sequentially inserted one by one in the front or rear projection insertion groove 120 of the mounting block 100, projection insertion groove It shall be arranged at equal intervals along (120).

Therefore, the support band 3 is fixed to the mounting block 100 because the locking protrusion 122 is inserted into the protrusion insertion groove 120 is fixed.

Of course, the shape of the locking projection 122 and the projection insertion groove 120 of the band fixing means is not limited to the spherical shape as shown, it may be variously formed in a square or triangle, depending on the case.

In addition, the support band 3 may be fixed to the mounting block 100 using screws or nails without forming the locking protrusion 122 and the protrusion insertion groove 120 in the mounting block 100.

In addition, the band fixing means may be formed in the shape of a ring, as shown, and the support band 3 may be penetrated and fixed to the ring.

In more detail, a plurality of rings standing on the upper surface of the mounting block 100 can be fixedly installed at equal intervals, and the support band 3 can be configured to penetrate the inner circumferential surface of the ring, so that the support in this configuration The band 3 is fixed without being flowed on the mounting block 100 by being partially constrained to the ring.

Subsequently, in the present invention, the lower end of the roof vinyl 2a is fixed to the lower end fixing part 212 on the outer circumferential surface thereof, and wound around the roof vinyl 2a as it is rotated by the rotation driving force of the winding motor M1 provided integrally. While lifting up and down includes a winding rod 210 for opening and closing the roof (2).

Here, the vinyl lower end fixing portion 212 forms a vinyl accommodating groove 212a in the axial direction on the outer circumferential surface of the winding rod 210 as shown in FIG. 5 to insert the lower end of the roof vinyl 2a, and the vinyl accommodating groove. The roof vinyl 2a is supported by the support piece 212b by inserting the support piece 212b formed to be inserted into the 212a into the vinyl accommodating groove 212a and fastening the winding rod 210 with the fastening member 212c. It was configured to be pressurized by the fixed by.

At this time, the support piece 212b is inserted along the vinyl accommodating groove 212a and preferably formed long in the axial direction of the winding rod 210 so as to pressurize and support the entire lower end of the roof vinyl 2a.

Therefore, the lower end of the roof vinyl 2a is pressed against the support piece 212b and firmly fixed to the vinyl accommodating groove 212a of the winding rod 210.

However, in order to more firmly fix the roof vinyl 2a to the winding rod 210, at least one rib R 'as shown inside the support piece 212b is formed to form the rib R'. The roof vinyl (2a) should be secured by wedges.

Meanwhile, the reason for forming and fixing the vinyl accommodating groove 212a in the winding rod 210 is to prevent the support piece 212b and the fastening member 212c from protruding to the outer circumferential surface of the winding rod 210. .

If the lower end of the roof vinyl 2a is wound around the outer circumferential surface of the winding rod 210 in which the vinyl accommodating groove 212a is not formed and then fixed by the support piece 212b and the fastening member 212c, the support piece 212b is provided. Due to the thickness of the fastening member 212c, the roof vinyl (2a) is wound in a laminated manner is projected from the support piece (212b) and the fastening member (212c) portion, whereby the protruding portion is the support band (3) It can get caught and damage or wrinkle the vinyl.

However, when the vinyl accommodating groove 212a is formed in the winding rod 210 to fix the branched inyl 2a therein, the roof vinyl 2a can be prevented from protruding from the roof vinyl 2a. (3) can be prevented.

Still further, the present invention includes winding rod horizontal holding means 300 which is installed at both ends of the winding rod 210 to maintain the horizontal while inducing the lifting of the winding rod 210, the winding rod horizontal holding means ( 300 is an arcuate structure in which pinions 310 are integrally provided at both ends of the winding rod 210 that are rotated as shown in FIGS. 2 to 4, and the pinions 310 are supported on both sides of the roof 2 while being engaged with each other. Each of the racks 320 is provided so that the pinions 310 at both ends travel along the circumference of the arcuate rack 320 while the winding rods 210 rotate to induce ascending and descending at the same time. It was configured to.

Here, the arcuate rack 320 may post a post 500 having a horizontal plate 502 at the top of the roof 2, for example, to be fixed on the horizontal plate 502. Alternatively, the horizontal plate 502 may be mounted on the already installed arch frame 1 and fixed thereon.

Of course, the post 500 may be installed directly on the upper end of the post 500 without installing the horizontal plate 502, or alternatively, it may be installed on the upper portion of the arch frame 1 so as to be integrated with the arch frame 1. In addition, both ends of the arcuate rack 320 may be formed to be formed long downward to reach the ground.

On the other hand, on both sides of the pinion 310 is provided with a guide plate 350 for guiding the running while preventing the pinion 310 running by supporting both sides of the arcuate rack 320.

At this time, the lower portion of the guide plate 350 is preferably mounted to the roller 352 to assist the driving of the pinion 310 by being in close contact with the lower surface of the arcuate rack 320 when the pinion 310 is running, in this case The guide plate 350 can guide the traveling of the pinion 310 more easily by this roller 352.

The winding rod horizontal holding means 300 is configured so that when the winding rod 210 is rotated by the winding motor M1, the pinion 310 of both ends of the winding rod 210 also rotates and runs along the arcuate rack 320. Both ends of the winding rod 210 are elevated while maintaining the same height, that is, the pinion 310 is smoothly traveled without being separated from the arcuate rack 320 by the guide plate 350.

Finally, the present invention restrains a part of the support band (3) to adjust the tension of the support band (3) while selectively pulling or unwinding the support band (3) in accordance with the winding operation of the winding rod (210) It includes a tension control means (400).

Here, the band tension adjusting means 400 is a plurality of shafts respectively installed in the longitudinal direction of the roof (2) in a plurality of valleys (V) formed in the lower portion between the roof (2) facing each other as shown in Figs. 410 and a plurality of support members 420 fixed to the valleys V to rotatably support the shaft 410.

Then, the band tension adjusting means 400 is connected to the drive motor M2, the transmission member 430 for transmitting the driving force to the plurality of shafts 410 and rotating at the same time, and eccentrically installed on the shaft 410 a plurality A plurality of eccentric disc pulleys 450 as shown in FIGS. 2 and 6 to adjust tension by pulling or releasing the support band 3 while being eccentrically rotated when the shaft 410 is rotated and constrained by a portion of the two support bands 3. It consisted of.

At this time, the support member 420 is composed of a plate mounted with a circular bearing 422 in the center as shown in Figure 2 to be fixed to the rain gutter 4, the shaft 410 on the circular bearing 422 ) To be fixed to the rain gutter 4 in a rotatable state.

Of course, the support member 420 may be fixed to the lower end of the arch frame 1 without fixing the rain gutter 4, and a bar-shaped bending bar bent in a 'π' shape instead of a plate member. It may be applied so that the shaft 410 is placed on the top.

That is, the 'π' shaped banding bar may be installed in the standing position at the lower end of the rain gutter 4 or the arch frame 1, and the shaft 410 may be raised on the upper end thereof.

Meanwhile, the transmission member 430 is installed in the driving motor M2 and rotates with the driving pinion 432 and the driving pinion 432 as shown in FIGS. 2 and 3 to drive the driving motor M2. The horizontal rack 434 reciprocating in the direction of the shaft 410 and the plurality of shafts 410 are respectively installed at the end of the shaft and engaged with the horizontal rack 434, the plurality of shafts while rotating in the reciprocating of the horizontal rack 434 It consists of a driven pinion 436 which rotates 410.

At this time, the horizontal rack 434 is to be mounted on the horizontal plate 502 of the post 500 shown as shown above, such that the vertical load due to its own weight is supported in the lower, the horizontal plate 502 In the upper part of the), the flow prevention port 434a which prevents the horizontal rack 434 reciprocating by supporting both sides of the horizontal rack 434 to flow in both directions, and in close contact with the lower surface of the horizontal rack 434 It is preferable to provide a guide roller 434b for movement.

Accordingly, the horizontal lever 434 does not flow to both sides by the flow preventing opening 434a when the driving pinion 432 is driven by the driving motor M2, and smoothly reciprocates on the guide roller 434b. .

When the horizontal lever 434 reciprocates as described above, the driven pinion 436 integral with the shaft 410 is also rotated by the horizontal lever 434, and thus the shaft 410 also rotates in association.

Of course, the horizontal rack 434 rotates the plurality of shafts 410 at the same time as shown.

As such, when the shaft 410 is rotated, the eccentric disc pulley 450 also performs the pulling operation of the support band 3 while the eccentric rotation or the release of the pulling operation.

That is, the eccentric disc pulley 450 pulls the support band 3 while rotating downward as shown by the solid line of FIG. 8 to be described later, and releases the pulling operation while returning to the original position as shown by the dotted line. Relax the tension in (3).

On the other hand, on the outer circumferential surface of the eccentric disc pulley 450 is provided with an idle idle bearing 455 of idle rotation as shown in Figure 7, the support band 3 is pulled or released during eccentric rotation is the eccentric disc pulley 450 ) To prevent winding on the outer circumferential surface.

If the idle bearing 455 is not installed, the support band 3 is wound due to the frictional force on the outer circumferential surface of the eccentric disc pulley 450, and when it is wound, the support band (rotational side of the eccentric disc pulley 450) ( 3) is wound more than the opposite support band (3).

That is, the eccentric disc pulley 450 does not pull the support band 3 uniformly in both directions, and only pulls the rotation direction side further.

However, when the idle idle bearing 455 is installed in this way, the support band 3 is not wound on the outer circumferential surface of the eccentric disc pulley 450 due to the idle rotation of the idle bearing 455, so that the eccentric disc pulley 450 is supported. The band 3 can be pulled uniformly in both directions.

In more detail, the eccentric disc pulley 450 pulls the support band 3 downward while eccentrically rotating during forward rotation of the shaft 410, and the support band 3 pulls the eccentric disc pulley 450. At the same time as the tension due to the force and friction with the idle bearing 455, the idle force 155 idling the friction bearing.

Therefore, the support band 3 is not wound on the outer circumferential surface of the eccentric disc pulley 450 by the idle idle bearing 455, thereby the eccentric disc pulley 450 uniformly supports the support band 3 in both directions I can pull it.

The reverse rotation of the eccentric disc pulley 450, that is, the upward eccentric rotation is made in the opposite direction to the operation of the downward eccentric rotation. In this case, the idle bearing 455 is idling with the frictional force of the support band 3 and the eccentric disc pulley 450 ) Releases the support band 3 uniformly in both directions, whereby the support band 3 is relaxed in tension.

On the other hand, the outer circumferential surface of the eccentric disc pulley 450 is formed concave in the 'U' shape, and the inner circumferential surface of the idle bearing 455 is formed convex in the 'V' shape, when the idle bearing 455 is idle The outer circumferential surface and the inner circumferential surface were made in line contact so that the frictional resistance was reduced.

That is, the eccentric disc pulley 450 has a recessed outer circumferential surface like a general V belt pulley, and the idle bearing 455 has a sharply protruding center portion like the V belt.

Therefore, the eccentric disc pulley 450 and the idle bearing 455 can minimize the frictional resistance generated during idling due to the outer peripheral surface and the inner peripheral surface formed to be in line contact.

At this time, the idle bearing 455 is preferably formed of a rubber or urethane material to ensure the friction force for the support band (3) and at the same time to be inserted into the outer peripheral surface of the eccentric disc pulley (450).

The operating concept of the eccentric disc pulley 450 constructed and operated as described above is shown in FIG. 8, and the vertical direction formula for calculating the momentum of the eccentric disc pulley 450 rotating as shown in the figure is as follows.

Vertical formula

* ω = π / 30sec

Here, the diameter d of the shaft 410 and the radius r of the eccentric disc pulley 450 are numerical values according to the embodiment, and the size (diameter) of the shaft 410 and the eccentric disc pulley 450 manufactured according to the embodiment. And radius).

This vertical formula can be used to set the size of the shaft 410 and the eccentric disc pulley 450 by calculating the flow distance that the support band 3 is pulled, otherwise the shaft 410 and the eccentric disc pulley ( It can also be used to calculate the flow distance of the support band (3) according to the size of 450.

On the other hand, the eccentric disc pulley 450 has to relax the support band (3) by winding upward eccentric rotation when the roof vinyl (2a) of the winding rod 210 described above, and again when the winding of the roof vinyl (2a) is completed again Eccentric rotation should tension the support band (3).

In other words, after the eccentric disc pulley 450 relaxes the support band 3 first, the winding rod 210 should wind the roof vinyl 2a, and when the winding of the winding rod 210 is completed, the eccentric disc pulley ( 450 again has to tension the support band (3).

Therefore, the winding rod 210 is not subjected to the interference of the support band 3 when the roof vinyl 2a is wound, and is firmly fixed by the support band 3 after the winding is completed.

Since the support band 3 does not interfere with the winding of the winding rod 210, the winding rod 210 has a height H (approximately 3.8 m) close to the mounting block 100 installed on the roof 2 as shown in FIG. 4. It can be lifted up and down to open and close most of the roof (2).

As described above, the roof automatic complete opening and closing system of the interlocking vinyl greenhouse according to the present invention includes a vinyl lower fixing part provided at a lower end of the roof vinyl 2a wound on the winding rod 210 to the inside of the winding rod 210. Since it is inserted into and fixed to 212, even if the roof vinyl 2a is wound around the winding rod 210, a part thereof does not protrude to the outer circumferential surface.

Then, the winding rod 210 is both ends by the winding rod horizontal holding means 300 to the same height, it can be a winding operation and lifting operation while maintaining a horizontal state.

In addition, since the tension of the support band 3 can be selectively adjusted, not only the interference of the support band 3 to the winding rod 210 can be prevented, but also the winding of the mounting block 100 of the roof 2 to the lower end. The rod 210 may be wound to open and close the entire roof 2.

The above embodiment is merely a description of the preferred embodiment of the present invention, the scope of application of the present invention is not limited to such, and can be changed as appropriate within the scope of the same idea.

Accordingly, the components, shapes, structures, and the like shown in the embodiments of the present invention may be modified and implemented, and such modifications are naturally within the scope of the appended claims.

The roof automatic complete opening and closing system of the interlocking vinyl greenhouse according to the present invention as described above, the tension of the plurality of support bands can be automatically adjusted by the band tension adjusting means, so that the winding rod can be raised and lowered to the top of the roof. Opening and closing is possible, thereby circulating the air in the room at once.

In addition, it is possible to prevent the support band from interfering when the winding rod is wound, thereby preventing damage to the roof vinyl due to friction with the supporting band, and the winding rod is elevated in a horizontal state due to the winding rod horizontal holding means. It is also possible to prevent the roof vinyl from being wound at an angle, thereby preventing the winding rod from bending.
