Description

[Technical field]

[0001] The present invention relates to an agricultural work support system, for example, to an agricultural work support system that reduces the labor involved in harvesting agricultural products such as vegetables and fruits grown in vinyl greenhouses. [Background technology]

[0002] Generally, when harvesting agricultural products grown in vinyl greenhouses, workers put the harvested agricultural products in baskets, load the baskets onto carts, and carry them outside the greenhouse. In this harvesting work, workers repeatedly squat and stand, which puts a lot of strain on their legs and back, and can even hurt their backs. In other words, the conventional agricultural harvesting work had a problem of putting an excessive strain on workers.

[0003] Furthermore, as a technology for reducing the labor required for harvesting agricultural crops, Patent Document 1 proposes an agricultural work assistance robot that transports agricultural crops by autonomous driving. The agricultural work assistance robot described in Patent Document 1 has a main body provided with a crop placement section on which harvested crops are placed, a signal receiving section that receives a worker-side signal from a transmitter carried by the farm worker, a control section to which the signal received by the signal receiving section is input, and a power supply section that supplies power to the control section and the signal receiving section. In addition, a moving means for moving the crop placement section and the main body is provided below the crop placement section and the main body.

[0004] In addition, the above-mentioned agricultural work assistance robot is provided with obstacle detection sensors on at least the front side of the main body in the direction of travel and on both sides widthwise relative to the direction of travel, which detect obstacles such as ridges or crop stumps and transmit obstacle detection signals to the control unit, and the control unit is configured to avoid the obstacles based on the obstacle detection signals, and to drive and control the moving means to move in the direction of the farm worker based on a signal from the worker.

[0005] [Patent Document 1] JP 2005-66809 A Summary of the Invention [Problem to be solved by the invention]

[0006] Incidentally, the above-mentioned agricultural work assistance robot transports harvested crops by automatic driving, thereby reducing the labor required from workers to carry the harvested crops on a cart or the like. However, this agricultural assistance robot is equipped with a control unit (a computer with special shiftware installed and a specially developed control circuit) that has advanced functions such as automatically driving and avoiding obstacles when they are detected, and this poses the issue of being costly. It should be noted that the above-mentioned agricultural work assistance robot is specialized only for transporting harvested products, and is not intended to reduce the physical burden on workers when harvesting crops.

[0007] The present invention has been made in consideration of the above problems, and has an object to provide a low-cost agricultural work support system that reduces the burden on workers during agricultural work. [Means for solving the problem]

[0008] The present invention, which has been made to solve the above-mentioned problems, is an agricultural work support system comprising: a hanger rail attached to a beam portion near the ceiling of a vinyl greenhouse in which agricultural crops are harvested and extending in the depth direction of the vinyl greenhouse on the ceiling side of the vinyl greenhouse; a first movable body supported movably on the hanger rail and capable of reciprocating along the longitudinal direction of the hanger rail; a first hanging belt suspended from the first movable body; and a storage box for storing agricultural crops fixed to a lower end of the first hanging belt, wherein the storage box attached to the first movable body via the first hanging belt can be freely moved back and forth in the depth direction of the vinyl greenhouse along the hanger rail together with the first movable body when a worker applies a load in the depth direction.

[0009] According to the above configuration, when the storage box becomes full of agricultural products, the worker in the vinyl greenhouse stands up and pulls the storage box full of agricultural products to the vicinity of the entrance of the vinyl greenhouse, whereby the storage box suspended from the first movable body movably supported on the hanger rail can be easily transported. In other words, according to the present invention, it is not necessary to load the basket (storage box) containing the harvested agricultural products onto a cart or the like and transport it to the entrance of the vinyl greenhouse, or for the worker to carry the basket containing the agricultural products by hand, so the labor of the worker in the transportation work is significantly reduced.

[0010] Furthermore, the agricultural work support system of the present invention has a simple configuration including a hanger rail attached to the ceiling and nearby beams of a vinyl greenhouse, a first movable body supported for free movement on the hanger rail, and a storage box attached to the first movable body via a first hanging belt, and does not include a power supply unit (power source) or a computer (or a dedicated control circuit) like the agricultural work support robot described in Patent Document 1 mentioned above. In other words, compared to the agricultural work assistance robot described in Patent Document 1 mentioned above, the agricultural work support system of the present invention has fewer parts and can be introduced at low cost, and since its structure is simple, maintenance costs can also be reduced.

[0011] It is also desirable to have a second movable body that is movably supported on the hanger rail and can move back and forth along the longitudinal direction of the hanger rail, a second hanging belt suspended from the second movable body, and an approximately plate-shaped seat on which an operator can sit, fixed to the lower end of the second hanging belt, wherein the seat attached to the second movable body via the second hanging belt can be freely moved back and forth in the depth direction of the vinyl greenhouse along the hanger rail together with the second movable body by the operator applying a load in the depth direction.

[0012] According to the above configuration, a greenhouse worker can move the sheet and storage box to a position near the crops to be harvested, harvest the crops while sitting on the sheet, and store the harvested crops in the storage box while remaining in a seated position. Furthermore, after harvesting the crops in front of the sheet, the worker can move the sheet and storage box laterally while remaining in a seated position to the position of the unharvested "adjacent crops." Thus, according to the present invention, crops can be harvested while sitting on the seat, which reduces the number of times the worker has to squat and stand repeatedly inside the greenhouse, thereby easing the physical strain on the worker when harvesting crops.

[0013] Also, an agricultural work support system to be installed in an outdoor field where agricultural products are grown includes a framework structure having a plurality of generally U-shaped steel pipes arranged at a predetermined interval so as to straddle the agricultural products in a predetermined direction in which the agricultural products are grown in the field, the generally U-shaped steel pipes having a pair of straight pipe sections erected vertically to the field and a horizontal pipe section connecting upper ends of the pair of straight pipe sections, a hanger rail attached to the horizontal pipe section of the framework structure and extending in the predetermined direction above the agricultural products, a first moving body and a second moving body movably supported on the hanger rail and capable of reciprocating along the longitudinal direction of the hanger rail, a first hanging belt suspended from the first moving body, and a second moving body. The device has a second hanging belt that is suspended above the ground, a storage box for storing agricultural products fixed to the lower end of the first hanging belt, and an approximately plate-shaped seat on which an operator can sit, fixed to the lower end of the second hanging belt, wherein the storage box attached to the first moving body via the first hanging belt can be moved freely back and forth in the specified direction along the hanger rail together with the first moving body by the operator applying a load in the specified direction, and the seat attached to the second moving body via the second hanging belt can be moved freely back and forth in the specified direction along the hanger rail together with the second moving body by the operator applying a load in the specified direction.

[0014] According to the above configuration, a worker performing agricultural work in an outdoor field can move the seat and storage box to a position near the crops to be harvested, harvest the crops while sitting on the seat, and store the harvested crops in the storage box while remaining in a seated position. Furthermore, after harvesting the crops in front of the seat, the worker can move the seat and storage box laterally while remaining in a seated position to the position of the unharvested "adjacent crops." Thus, according to the present invention, when working in outdoor fields, crops can be harvested while sitting on a seat, reducing the number of times the worker has to squat and stand up, thereby easing the physical strain on the worker when harvesting crops outdoors.

[0015] According to the present invention, it is possible to provide a farm work support system at low cost that reduces the burden on workers during farm work. [Brief description of the drawings]

[0017] Hereinafter, a farm work support system W according to an embodiment of the present invention will be described with reference to the drawings.

[0018] <<Outline of the agricultural work support system W>> First, a schematic configuration of the farm work support system W of this embodiment will be described with reference to FIGS. 1 and 2. FIG. Here, Fig. 1 is a schematic diagram for explaining the overall configuration of the agricultural work support system installed in the vinyl greenhouse of the present embodiment. Fig. 2 is a schematic diagram for explaining the operation of the agricultural work support system installed in the vinyl greenhouse of the present embodiment.

[0019] The agricultural work support system W of this embodiment is installed, for example, inside a vinyl greenhouse 100 in which agricultural crops 200 are grown, and is intended to reduce the physical burden on workers (agricultural workers) when harvesting the agricultural crops 200, as well as the labor required to transport the harvested agricultural crops.

[0020] As shown in FIG. 1, the agricultural work support system W includes a hanger rail 3 that is attached to a beam portion (cross beam 105 in the illustrated example) near the ceiling of a vinyl greenhouse 100 and extends in the depth direction (Y direction) on the ceiling side (upper side) of the vinyl greenhouse 100, and a "tool carriage (first movable body) 5A(5), tool carriage (second movable body) 5B(5)" that is movably supported on the hanger rail 3 and can move back and forth along the longitudinal direction of the hanger rail 3. The tool carriage (first movable body) 5A(5) and the tool carriage (second movable body) 5B(5) are the same.

[0021] The hanger rail 3 extends in the depth direction (Y direction) from a position near the front surface of the vinyl greenhouse 100 where the entrance is provided to a position near the rear surface of the vinyl greenhouse 100. Inside the vinyl greenhouse 100, crops 200 are grown along the depth direction (Y direction).

[0022] In addition, a suspension belt (first suspension belt) 10a is suspended from the tool cart (first movable body) 5A, and a storage box 30 for storing harvested crops is attached (fixed) to the lower end of this suspension belt 10a. In addition, a hanging belt (second hanging rivet) 10b is suspended from the tool carriage (second movable body) 5B, and a roughly plate-shaped seat 20 on which a worker can sit is attached (fixed) to the lower end of the hanging belt 10b.

[0023] As shown in Figure 2, the storage box 30 (storage box 30 in a hanging state) suspended from the tool cart 5A via the suspension belt 10a can be freely moved back and forth in the depth direction (Y direction) of the greenhouse 100 along the hanger rail 3 together with the tool cart 5A by an operator pulling it by hand (by applying a load in the depth direction (Y direction)). In addition, the sheet 20 (sheet 20 in a hanging state) is suspended via suspension belts 10b from the tool cart 5B, which is supported so as to be freely slidable on the hanger rail 3, and can be freely moved back and forth in the depth direction (Y direction) of the greenhouse 100 together with the tool cart 5B along the hanger rail 3 by the worker pulling it by hand (by applying a load in the depth direction (Y direction)).

[0024] According to this configuration, a worker in the vinyl greenhouse 100 can move the sheet 20 and the storage box 30 to a position near the crops 200 to be harvested, then harvest the crops 200 while sitting on the sheet 20, and store the harvested crops 200 in the storage box 300 while remaining in the seated position. In addition, after harvesting the crops in front of the sheet 20, the worker can, while remaining seated, shift the sheet 20 and storage box 30 laterally (in the Y direction) to move to a position in front of the unharvested “adjacent crops 300.” In this manner, according to this embodiment, crops 200 can be harvested while sitting on seat 20, and therefore the physical burden on the worker during crop harvesting work is reduced.

[0025] Furthermore, when storage box 300 is full of stored crops 200, the worker stands up and pulls storage box 30 full of crops 200 to the vicinity of the surface of vinyl greenhouse 100 where the entrance is provided, thereby easily transporting storage box 30 suspended from tool compound cart 5A movably supported on hanger rail 3. That is, according to this embodiment, it is not necessary to load storage box 300 containing harvested crops onto a cart or the like and transport it to the entrance of vinyl greenhouse 100, or for the worker to carry storage box 300 containing crops by hand, and therefore the labor of the worker in the transportation work is significantly reduced.

[0026] Furthermore, the agricultural work support system W of this embodiment is configured to have a hanger rail 3 attached to a beam (cross beam 103 in the illustrated example) near the ceiling of a vinyl greenhouse 100, tool carts (first and second movable bodies) 5A, 5B supported for free movement on the hanger rail 3, and a sheet 20 and a storage box 30 suspended from the tool carts 5A, 5B via suspension belts 10a, 10b, and is not equipped with a power source or computer (or dedicated control circuit) like the agricultural work support robot described in Patent Document 1 mentioned above. In other words, compared to the agricultural work assistance robot described in Patent Document 1 mentioned above, the agricultural work support system W of this embodiment has fewer parts and can be introduced at low cost, and since its structure is simple, maintenance costs can also be reduced.

[0027] Components of the Agricultural Work Support System W Hereinafter, the vinyl greenhouse 100 to which the agricultural work support system W of this embodiment is attached and each component of the agricultural work support system W will be described with reference to the above-mentioned Figs. 1 and 2 and Figs. 3 to 6. Here, FIG. 3 is a schematic diagram showing the state in which the hanging belt, sheet, and storage box are removed from the agricultural work support system installed in the vinyl greenhouse of this embodiment. FIG. 4 is a schematic diagram showing a single pipe lower bracket constituting the agricultural work support system of this embodiment, and FIG. 5 is a schematic diagram showing a hanger rail constituting the agricultural work support system of this embodiment. FIG. 6 is a schematic diagram showing a tool cart constituting the agricultural work support system of this embodiment, and FIG. 7 is a schematic diagram showing a door stop constituting the agricultural work support system of this embodiment.

[0028] "100 Greenhouses" First, a brief description will be given of the vinyl greenhouse 100 to which the farm work support system W of this embodiment is attached. As shown in Figure 3, the vinyl greenhouse 100 has a number of arch pipes (steel pipes) 101 arranged in a row at a predetermined interval in the depth direction (Y direction), and a ridge pipe (steel pipe) 102 and main house pipes (steel pipes) 103, 104 that extend in the depth direction (Y direction) to connect the multiple arch pipes 101. The ridge pipe 102 and the main pipes 103, 104 are made of straight pipes.

[0029] In addition, the arch pipe 101 has a pair of straight pipe sections 101a, 101a that are erected vertically (in the Z direction) relative to the installation surface (ground), and an arch-shaped arch section 101b that connects the upper ends of the pair of straight pipe sections 101a, 101a. In each arch pipe 101, an upper portion of one straight pipe portion 101a and an upper portion of the other straight pipe portion 101a are connected by a horizontal beam (beam portion) 105 formed of a straight pipe extending in the horizontal direction (X direction).

[0030] The vinyl greenhouse 100 has a framework structure formed by a number of arch pipes 101, a number of "ridge pipes 102 and main house pipes 103, 104", and a number of cross beams 105, and this framework structure is covered with a vinyl sheet (not shown).

[0031] Furthermore, a single-pipe lower bracket 1 for supporting the hanger rail 3 is attached to the cross beam 105 that forms the framework structure of the vinyl greenhouse 100 (multiple single-pipe lower brackets 1 are attached), and the hanger rail 3 is attached to the cross beam 3 via the multiple single-pipe lower brackets 1. In the example shown in Figure 3, a single pipe lower bracket 1 is attached to each of the three cross beams 105, and a hanger rail 3 is installed so that it extends in the depth direction (Y direction) of the vinyl greenhouse 200 using the three single pipe lower brackets 1. Below, each component of the agricultural work support system W will be explained in order.

[0032] {Single pipe bottom bracket 1} As shown in Fig. 4, the single pipe lower bracket 1 has a body portion 1a having a substantially U-shaped cross section, which includes a substantially flat upper surface portion 1a1 and a pair of side portions 1a2, 1a2 extending downward at a substantially right angle from both the left and right sides of the upper surface portion 1a1. In addition, inner flange portions 1a3 are formed at the lower ends of the pair of side portions 1a2, 1a2, which are bent at a substantially right angle in a direction approaching each other (inward direction). Furthermore, the upper surface portion 1 is provided with a fastening portion 1c for fixing a hanger rail 3 on the inner portion of the main body portion 1a.

[0033] A cylindrical portion 1e is protruding from the upper surface portion 1a, and a straight pipe gripping portion 1f having a substantially C-shape is provided at the upper end of the cylindrical portion 1e. A fastening portion 1g consisting of a bolt and a nut is provided at the end of the straight pipe gripping portion 1f having a substantially C-shape.

[0034] Then, the cross beam 103 is inserted inside the straight pipe gripping portion 1f having a substantially C-shape, and the fastening portion 1g is tightened. The straight pipe gripping portion 1f clamps the cross beam 3, and the single pipe lower bracket 1 is fixed in a hanging state to the cross beam 3. In addition, when the single pipe lower bracket 1 is fixed in a hanging state to the cross beam 3, the outer periphery of the hanger rail 3 is inserted into the gap formed by the inner part of the main body portion 1a, i.e., the top surface portion 1a1, the pair of side surfaces 1a2, 1a2, and the inner flange portion 1a3, and the fastening portion 1c is fastened, whereby the hanger rail 3 is attached to the cross beam 105 via the single pipe lower bracket 1.

[0035] "Clothes rail 3" As shown in FIG. 5, the hanger rail 3 is formed in a generally U-shape in cross section with an upper surface 3a and a pair of side surfaces 3b, 3b extending downward at approximately right angles from both the left and right sides of the upper surface 3a, and inner flange portions 3c, 3c bent in a direction approaching each other (inward direction) are formed at the lower ends of the pair of side surfaces 3b, 3b. Further, at the ends of the inner flange portions 3c, 3c, folded-back portions 3d, 3d are formed which are bent upward at a right angle. Further, a gap 3s is formed between the inner flange portions 3c, 3c (folded-back portions 3d, 3d).

[0036] When the wheel portion 5b of the tool cart 5 (5A, 5B) is placed on the inner flange portion 3c of the hanger rail 3, the folded portion 3d comes into sliding contact with the side portion of the wheel portion 3b, allowing the tool cart 5 to move freely back and forth along the longitudinal direction (Y direction) of the hanger rail 3.

[0037] "Tour Double 5" As shown in FIG. 6, the tool compound cart 5 (5A, 5B) has a plate-like main body 5a having an approximately inverted circular triangle shape, axle portions 5b, 5b inserted rotatably on the upper and left and right sides of the main body 5a, and wheel portions 5c, 5c attached to both ends of each axle portion 5b. Further, a locking hole 5a1 for locking a ring-shaped member R for attaching the hanging belts 10a, 10b is provided on the lower end side of the main body 5a.

[0038] The tool cart 5 is supported movably inside the hanger rail 3 with the wheel portions 5b, 5b placed on the inner flange portions 3c on both sides of the hanger rail 3 and the lower end side of the main body portion 5a protruding downward from the gap portion 3s between the inner flange portions 3c of the hanger rail 3. With this configuration, the tool cart 5 can reciprocate along the longitudinal direction (Y direction) of the hanger rail 3.

[0039] 1 and 2, a ring-shaped member R is attached to the locking hole 5a1 formed in the lower end side of the main body 5a of the tool cart 5 protruding from the hanger rail 3. Suspension belts 10a, 10b are suspended from this ring-shaped member R, and a storage box 30 for storing harvested crops and a roughly plate-shaped seat 20 on which a worker can sit are attached to the lower ends of the suspension belts 10a, 10b. The hanging belts 10a, 10b have one end fixed to the link-shaped member R and the other end capable of fixing the sheet 20 or the storage box 30, and are strong enough to hold the sheet 20 or the storage box 30 in a suspended position even when a worker is sitting on the sheet 20 or when agricultural products are stored in the storage box 30, and there are no particular limitations on their shape or material.

[0040] The seat 20 is formed in a rectangular flat plate shape and can be made of any material as long as the worker can sit on it, and can be made of synthetic resin or wood. The container box may be, for example, a rectangular box that is open at the top.

[0041] "stopper" The stoppers 6 are attached to both ends of the hanger rail 3 and function as stopper members to prevent the tool cart 5, which is slidably supported on the hanger rail 3, from falling off the hanger rail 3.

[0042] Specifically, as shown in FIG. 7, the stopper 6 includes a U-shaped main body 6a, a bolt 6b which penetrates the upper surface of the main body 6a and has a shaft which protrudes below the lower end of the main body 6a, a washer 6c which is inserted into the shaft of the bolt 6b, and a nut 6d which is screwed onto the shaft of the bolt 6a. Further, elastic portions 6e, 6e made of rubber or the like are provided on both sides of the main body portion 6a. The stopper 6 is inserted into the hanger rail 3 and fixed to both ends inside the hanger rail 3 by tightening the bolts 6b and nuts 6d.

[0043] In this way, according to the agricultural work support system W of this embodiment, it is not necessary to load baskets containing harvested crops onto a cart or the like and carry them to the entrance or exit of the vinyl greenhouse 100, or for the workers themselves to lift and carry the baskets containing the crops, so the labor required for transportation by the workers is significantly reduced. In addition, according to the agricultural work support system W of this embodiment, the worker can harvest the crops 200 while sitting on the seat 20 and place the crops into the storage box 30 while still sitting, thereby reducing the physical burden on the worker when harvesting the crops.

[0044] Furthermore, compared to the agricultural work assistance robot described in Patent Document 1 mentioned above, the agricultural work support system W of this embodiment has fewer parts and can be introduced at low cost, and since its structure is simple, maintenance costs can also be reduced.

[0045] As described above, according to this embodiment, a farm work support system that reduces the burden on workers during farm work can be provided at low cost.

[0046] The present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the present invention.

[0047] Although the farm work support system W in the embodiment described above is installed inside the vinyl greenhouse 100, the present invention is not particularly limited to this. A framework structure made of steel pipes may be installed in a field where outdoor crops are grown in order to install the agricultural work support system W, and the above-mentioned agricultural work support system W may be installed in the upper part of the framework structure.

[0048] The above-mentioned framework structure may be the same as the framework structure of the vinyl greenhouse 100 in FIG. 3 described above, or may be a structure simpler than that of the vinyl greenhouse 100. The simplified framework structure, for example, has a plurality of roughly U-shaped steel pipes arranged at a predetermined interval so as to straddle the crops in a predetermined direction in which the crops are grown in an outdoor field. The roughly U-shaped steel pipes have a pair of straight pipe sections that stand vertically to the field, and a horizontal pipe section that connects the upper ends of the pair of straight pipe sections. In addition, it is desirable for the simplified framework structure to have multiple "approximately U-shaped steel pipes" connected by a straight pipe (steel pipe) extending in a predetermined direction. Then, clamp members are attached to each of the horizontal pipe sections constituting the roughly U-shaped steel pipes that are arranged in a row at specified intervals along a specified direction, and rail underlays (rail underlays made of straight pipes (steel pipes)) extending in the specified direction are attached to the clamp members. Single pipe lower brackets 1 for supporting the hanger rail 3 are attached to these rail underlays (straight pipes (steel pipes)), and the hanger rail 3 is attached to the multiple single pipe lower brackets. That is, the hanger rail 3 is attached to the horizontal pipe section via the single pipe lower bracket 1 and the rail underlay material.

[0049] In the above explanation, the rail underlay is attached to the horizontal pipe section via a clamp member, the single pipe lower bracket 1 is attached to the rail underlay, and the hanger rail 3 is attached to the single pipe lower bracket 1, but this is just one example. For example, the single pipe lower bracket 1 may be attached directly to the horizontal pipe section constituting a roughly U-shaped steel pipe, and the hanger rail 3 may be attached to the single pipe lower bracket 1. In this case, the rail underlay (and clamp member) will not be necessary.

[0050] Specifically, the agricultural work support system installed in an outdoor field where agricultural crops are grown has a framework structure having a plurality of roughly U-shaped steel pipes arranged at a predetermined interval so as to straddle the agricultural crops along a predetermined direction in which the agricultural crops are grown in the field. The roughly U-shaped steel pipes have a pair of straight pipe sections that are erected vertically to the field, and a horizontal pipe section that connects the upper ends of the pair of straight pipe sections. In addition, the agricultural work support system installed in a field where outdoor crops are grown includes a hanger rail 3 that is attached to the horizontal pipe portion of the framework structure via a single-pipe lower bracket 1 (or a single-pipe lower bracket and a rail underlay 1) and extends in the specified direction above the crops, a tool cart 5 (5A, 5B) that is movably supported on the hanger rail 3 and can move back and forth along the longitudinal direction of the hanger rail 3, a first suspension belt 10a suspended from the tool cart 5A, a second suspension belt 10b suspended from the tool cart 5B, a storage box 30 for storing crops that is fixed to the lower end of the first suspension belt 10a, and a seat 20 on which a worker can sit that is fixed to the lower end of the second suspension belt 10b. When an operator applies a load in a predetermined direction to the storage box 30, the storage box 30 can be moved back and forth in a predetermined direction together with the tool cart 5A along the hanger rail 3. When an operator applies a load in a predetermined direction to the sheet 20, the sheet 20 can be moved back and forth in a predetermined direction together with the tool cart 5B along the hanger rail 3.

[0051] According to this configuration, when working in an outdoor field, crops can be harvested while sitting on the seat 20, which reduces the number of times the worker has to squat and stand repeatedly, thereby reducing the physical strain on the worker when harvesting crops outdoors.

[0052] In the above embodiment, the hanger rail 3 is attached to the cross beam (steel pipe) 105 of the framework structure of the vinyl greenhouse 100 via the single pipe lower bracket 1, but this is merely an example. The framework structure of the vinyl greenhouse 100 shown in FIG. 3 is also merely an example. In the present invention, it is sufficient that the hanger rail 3 is attached via the single pipe lower bracket 1 to the ceiling part or the nearby part (steel pipe) in the framework structure that constitutes the vinyl greenhouse 100 .
