Description

{Harvest carrying device installed in vinyl greenhouse}

The present invention reduces the sagging of the greenhouse harvest transport device and the upper rail of the greenhouse through a device for reducing the deflection of the greenhouse harvest transport device and the upper rail, thereby preventing the rollers that transport the greenhouse harvest transport device from getting caught in the rail, thereby enabling cultivation inside the greenhouse. This relates to a harvest transport device for installing greenhouses that allows more stable transport of agricultural crops.

Vinyl greenhouses have the advantage of being easy to construct and providing sufficient thermal insulation, so most farms use greenhouses to grow various crops such as fruits and vegetables.

However, due to the high temperature and humidity inside the greenhouse and the limited space, there are many difficulties in harvesting crops and moving them outside the greenhouse. In particular, when the space between crops is small and the harvested product is transported using a basket or cart, there is a problem of damage to the crops or fruits.

To solve this problem, various types of greenhouse harvest transport equipment have been proposed, in which rails and rollers are installed on the ceiling and sides of the greenhouse frame, and these are connected to a transport truck using a connecting frame to move them.

However, the greenhouse frame sags due to various causes such as ground settlement over time, wind, snow, and changes in the weight of crops loaded on the cart, and the rails installed in the frame are also affected by the sagging. However, the harvest transport equipment applied to conventional greenhouses has a problem in that the rollers become stuck in the rail and do not move or are separated from the rail due to deformation such as sagging of the greenhouse frame.

In particular, in the case of Korean Patent Publication No. 10-2013-0000168, a transport device for greenhouses is proposed in which a number of rails are fixed at regular intervals to the support frame at the top of the greenhouse and the loading box moves back and forth along the rails. If the spacing between rails is not parallel due to bending or sagging of the house frame, a problem occurs where the roller comes off the rail.

Referring to these drawings, the harvest transport device for installing a greenhouse according to an embodiment of the present invention includes an upper transport device 100 installed to extend longitudinally in the middle of the inside of the greenhouse, and side parts installed to extend longitudinally on both sides. Transport device 400, transport tool 500 connected to the upper transport device 100 and side transport device 400, transport hanger 130 connecting the upper transport device 100 and transport tool 500, upper rail sagging It includes a reduction device 200, a vehicle deflection reduction device 600, a vehicle drive unit 700, and a control unit for controlling the drive unit.

The upper transfer device 100 and the side transfer device 400 largely include rails connected longitudinally along the structural frame A of the greenhouse, and rollers moved longitudinally within the rails.

Referring to Figures 2 and 4 together, the upper transport device 100 includes an upper rail 110 installed longitudinally on the upper part of the greenhouse frame (A); It is configured to include; an upper roller 120 capable of moving in the longitudinal direction within the upper rail 110.

The upper rail 110 is fastened at regular intervals by a plurality of semicircular clamps 250 to the bottom of the support frame 210 installed in the longitudinal direction to support the structural frame A of the greenhouse.

At this time, the support frame 210 is a cylindrical or oval-shaped pipe with a wire rope 220 installed therethrough, and the upper rail 110 includes a body 111 having a square cross-section, and the body It consists of a guide hole 112 formed in the longitudinal direction on the bottom of the guide hole 111, and a locking protrusion 113 extending to the upper end of both ends of the guide hole 112.

That is, since the moving part 114 of the upper roller 120 is inserted and rotated by the inner surface of the body 111 and the locking protrusion 113, the upper roller 120 maintains a horizontal state and moves longitudinally on the rail. moves to .

The side transfer device 400 includes side rails 410 installed longitudinally on the left and right sides of the greenhouse frame frame (A), and side rollers 420 that can move longitudinally within the side rails 410. It is composed.

As shown in FIG. 3, the side rails 410 are installed to extend longitudinally along both sides of the inside of the greenhouse. For this purpose, the side rails 410 are installed vertically at regular intervals on the side of the greenhouse. The fixing clamp 471 is fastened.

The rail fixing clamp 471 is fastened with a bolt to the back plate 472, which is provided in a round shape to cover the rear of the greenhouse side frame 470, and the back plate 472 with the side frame 470 in between. It consists of a front plate 473. One side of the front plate 473 is provided with a double vertically bent wing portion 474.

When a pair of rail fixing clamps (471) are fastened to the side frame (470) to face each other up and down at a certain distance, the roller guide (460) is moved by the upper and lower wings (474) of the facing front plate (473). A space is formed into which a can be inserted.

The roller guide 460 is inserted between a pair of rail fixing clamps 471. The roller guide 460 has a generally 'ㄷ'-shaped cross-section and is provided with both ends vertically bent inward, so that the inserted side roller 420 moves in the longitudinal direction within the rail without being separated.

An upper roller connector 140 and a side roller connector 450 are connected to the upper rail 110 and the side rail 410, respectively. The upper roller connection body 140 and the side roller connection body 450 transport the carriage 500 by rollers running along the upper rail 110 and the side rail 410, respectively.

In one embodiment, the upper roller connector 140 has an upper roller 120 running along the upper rail 110, one side of which is installed on the upper roller 120, and the other side of which is connected to the central part of the transportation device 500. Includes (130).

In one embodiment, the side roller connector 450 includes a plurality of side rollers 420, a roller alignment frame 430 in which the plurality of side rollers 420 are aligned and fixed at regular intervals, and a transport device 500 is fixed. It includes a transport fixing plate 440 and a wire connection member to which a wire is connected.

In this embodiment, it has been described that a plurality of side rollers 420 are fixed to the roller alignment frame 430, but the number of side rollers 420 may be one. The side roller 420 is fixed to the roller alignment frame 430, so when the side roller 420 travels, the roller alignment frame 430 travels together.

The upper part of the transport fixing plate 440 is attached to the roller alignment frame 430, and the transport tool 500 is fixed to the lower part of the transport fixing plate 440.

The transport device 500 is placed with crops grown in a greenhouse, crops harvested from crops, or a box containing the harvest, and moves along the longitudinal direction of the greenhouse at a speed set in the control unit or by operation of a remote controller.

However, the greenhouse frame (A) experiences uneven deflection due to various causes such as ground subsidence, temperature changes, snow cover, and changes in the weight of crops loaded on the cart over time, and as a result, the structure that supports the frame frame (A) There is a risk that the strain may be transferred to the upper rail. However, the harvest carrier 500 applied to the conventional greenhouse cannot cope with deformation such as sagging of the upper rail due to sagging of the greenhouse frame (A) or sagging of the carrier 500, so the roller gets stuck in the rail and does not move. There is a problem with it coming off the rail.

In order to solve the problem of deformation or deflection of the carriage due to deflection of the upper rail due to deflection of the frame frame, the present invention includes an upper rail deflection reduction device 200 for reducing deformation related to deflection of the upper rail 110. And, the carriage deflection reduction device 600 is adopted to reduce the deflection of the carriage 500.

As shown in FIGS. 2 and 4 to 6, the upper rail sagging reduction device 200 has an upper rail 110 fastened to the bottom, and the top is cylindrical or has a cylindrical shape capable of supporting the structural frame (A) of the greenhouse. A support frame 210 composed of an oval-shaped pipe, a wire rope 220 installed through the inside of the support frame 210 to suppress sagging deformation of the upper rail together with the support frame due to tension, and the wire rope It is configured to include a wire rope tension maintenance means for maintaining the tension of (220).

The support frame 210 is supported by support frame support pillars installed at both longitudinal ends of the greenhouse, and the wire rope tension maintaining means is attached to a support pillar 240 for installing the wire rope tension maintaining means spaced apart from the support pillars. It is installed.

The wire rope tension maintaining means may be a hydraulic tension maintaining means in addition to the pulley-type (310) tension maintaining means and the spring-type (320) tension maintaining means as shown in FIGS. 5 and 6.

As shown in FIG. 5, the pulley-type tension maintaining means 310 is a pulley in which a major pulley 311 and a small pulley 312 are combined; and a pulley support 313, an upper support 314, and a lower support 315. It consists of a support base consisting of ), where a wire rope 220 penetrating the inside of the support frame 210 is connected to the small pulley 312, and a tension weight 316 is suspended from the large pulley 311, The tension of the wire rope 220 is maintained by the vertical movement of the tension weight 316.

The pulley-type tension maintaining means 310 ensures that when a load is applied to the frame frame for some reason and the support frame 210 is about to sag, tension due to the same load is added to the wire rope 220 penetrating the inside of the support frame. do. When tension is added to the wire rope, the wire rope tries to cause rotation of the small sheave because the minor sheave 312 is connected to the end of the wire rope 220, and when rotation of the minor sheave is caused, the major sheave (311) also tries to rotate in conjunction with the pulley, and the tension weight 316 is connected to the pulley, so the tension weight must rise. However, since the tension weight resists the load applied to the wire rope 220 while continuing to apply tension to the wire rope 220 connected to the small pulley through the large pulley above a certain load, the tension weight fastened to the support frame 210 The deflection of the upper rail 110 is reduced.

The spring-type tension maintaining means 320 is a means for maintaining the tension of the wire rope 220 using the elasticity of the spring 324, as shown in FIG. 6, and penetrates the middle barrel into the outer barrel 321, A coil spring is installed on the outside of the pierced middle barrel, and one end of the middle barrel is supported by the coil spring. Then, the inner barrel 323 is penetrated inside the middle barrel, and the coil spring 324 is installed on the outside of the inner barrel 323. However, one end of the inner tube 323 is connected to the wire rope 220 and the other end is supported by the coil spring 324.

Like the pulley-type tension maintaining means, the spring-type tension maintaining means 320, when a load is applied to the frame frame for some reason and sagging occurs in the support frame 210, the wire rope 220 penetrating the inside of the support frame The same tension is added. When tension is added to the wire rope, the inner tube 323 connected to the wire rope is pulled and the coil spring 324 is compressed. At this time, the elastic force generated as the coil spring 324 is compressed is applied to the wire rope. Since the tension of the wire rope is maintained by being transferred to the rope 220, the sagging of the upper rail 110 fastened to the support frame 210 is reduced.

In addition, the hydraulic tension maintenance means utilizes the volume change that occurs due to the expansion or contraction of the oil sealed in the cylindrical container due to changes in the external environment and converts this into piston movement to maintain the tension of the wire rope 220. .

As shown in FIG. 7, the vehicle deflection reduction device 600 includes a cylindrical support frame 610 installed at the lower part of the vehicle 500, a wire rope 620 penetrating the inside of the support frame 210, and the wire It is configured to include a wire rope tension maintaining means 630 that maintains the tension of the rope 620.

The wire rope tension maintaining means 630 used in the conveyance deflection reduction device 600 uses a spring-type (320) tension maintaining means and a hydraulic tension maintaining means, and only the attachment position is fastened to the tension maintaining means at both lower ends of the conveyance 500. Only the part 640 is different, and the operating method is the same as the upper rail deflection reduction device 200, so detailed description will be omitted.

By using a greenhouse harvest transport device equipped with the transport device and the upper rail deflection reduction devices 600 and 200 as described above, the upper rail 110 of the greenhouse due to the deflection of the harvest carrier 500 or the load applied to the upper part of the greenhouse is reduced. By reducing the sagging, the roller driving the harvest transport tool 500 can run smoothly on the side rail 410.

Meanwhile, referring to FIGS. 8 and 9 together, the drive unit 700 includes a wire 710 connected to the side roller connection body 450, and a wire 710 wound around the wire 710 to move the side roller connection body 450 forward or backward. A driving roller 720, a wire alignment roller 730 that presses the wire 710, a wire gap adjuster 740 that ensures that the wire 710 is consistently wound around the driving roller 720, and a driving roller ( It includes a drive motor 750 that drives 720).

One side of the wire 710 is connected to the wire connection member 760 fixed to one side of the side roller connector 450, and after being wound around the drive roller 720, it turns around a wire auxiliary roller (not shown) and connects the side roller again. It is connected to a wire connection member 760 fixed to the other side of the sieve 450. Accordingly, the side roller connection body 450 connected to the wire 710 moves forward or backward according to the forward or reverse rotation of the drive roller 720.

The wire 710 is wound around the driving roller 720 more than three times to prevent slipping when the driving roller 720 rotates. In addition, a wire alignment roller 730 is installed in front of the driving roller 720 to press the wire 710 from the top and bottom so that the wire 710 is in close contact with the driving roller 720 and prevents slipping. The wire alignment roller 730 applies strong tension to the wire 710, so that the wire 710 moves forward or backward without spinning when the driving roller 720 rotates.

The wire gap adjuster 740 is used to prevent the wire 710 from shaking due to gathering in one direction or being double wound when the driving roller 720 rotates and winds and pulls the wire 710. For this purpose, the wire spacing adjuster 740 is mounted on the lower part of the driving roller 720 around which the wire 710 is wound, and is spaced apart from the driving roller 720 at an interval that allows only one strand of wire 710 to pass. It is installed. Therefore, the wire 710 is wound around the drive roller 720 in a single layer rather than double.

The control unit 800 is equipped with a speed control switch 810 that controls the speed of the driving motor 750, a forward and reverse rotation switch 820, and an emergency stop switch 830 that can perform a complete stop in an emergency. In addition, it can be operated remotely by remote controller 840, so it can be easily moved forward, backward, or stopped during work, and can also be operated outside the greenhouse.

In addition, limit switches 850 are mounted on both ends of the roller guide 460, so that when the wire connection member reaches both ends of the roller guide 460, a signal is sent to the control unit 800 to automatically stop.

As described above, the harvest transport device for installing a greenhouse of the present invention is equipped with a transport tool and an upper rail deflection reduction device 200 to reduce greenhouse gases due to sagging of the transport tool 500 for transporting the harvest or the load applied to the upper part of the greenhouse. There is an advantage in that the deflection of the upper rail 110 can be reduced to allow the roller driving the harvest transport device 500 to run smoothly on the rail.

The present invention is not limited to the described embodiments, and it is obvious to those skilled in the art that various modifications and changes can be made without departing from the spirit and scope of the present invention. Accordingly, such modifications or variations will fall within the scope of the claims of the present invention.
