Description

[Technical field]

[0001] The present invention relates to a guide device. [Background technology]

[0002] Patent Document 1 discloses a guide device that guides a chemical hose when spraying agricultural chemicals. This guide device includes a base and a guide pulley that is provided on the base so that the rotation plane is horizontal to the ground. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Jpn. Jpn. Published No. 62-25589 Summary of the Invention [Problem to be solved by the invention]

[0004] The above-mentioned guide device is installed at a position where the direction of the hose is to be changed, and is used so that the hose is engaged with the pulley. However, the spraying operation is performed while changing the position of the spray target and while the hose is being unwound from the spray device. In this case, the relative positional relationship between the pulley and the hose changes, which easily changes the bending angle of the hose at the pulley, and it is considered that the hose may fall off the pulley.

[0005] An object of one embodiment of the present invention is to provide a guide device that can appropriately guide an elongated body (hose) even if the position of the elongated body changes. [Means for solving the problem]

[0006] One example of a guide device includes a guide portion (10) including a roller portion (11) that guides a long body (105a) that moves back and forth along the longitudinal direction, and a base portion (40) that supports the guide portion (10) from below, and the guide portion (10) is rotatable relative to the base portion (40).

[0007] In the above guide device, the long body (105a) moves in the front-rear direction while being guided by the roller portion (11) of the guide portion (10). In this case, even if the position of the long body (105a) changes in the left-right direction, the guide portion (10) rotates following the position of the long body (105a) because the guide portion (10) is rotatably provided with respect to the base portion (40). Therefore, the roller portion (11) and the long body (105a) are likely to form an appropriate positional relationship. Therefore, the long body (105a) can be appropriately guided.

[0008] The roller unit (11) may include a pair of first rollers (12) facing each other with the long body (105a) therebetween, a second roller (13) located below the first roller (12) and supporting the long body (105a) from below, and a frame (20) rotatably supporting the first roller (12) and the second roller (13). In this configuration, when the direction of the long body (105a) changes left and right at the position of the guide device, the long body (105a) is guided by the first roller (12). When the direction of the long body (105a) does not change left and right at the position of the guide device, that is, when the long body (105a) is guided linearly by the guide unit (10), the long body (105a) is guided by the second roller (13). Since rollers are provided on the left, right and bottom of the long body (105a), the long body (105a) is guided by one of the rollers.

[0009] The base (40) may include a shaft (48) that protrudes upward along the rotation axis of the guide part (10), and the frame (20) may include a lower surface that extends so as to intersect with the extending direction of the shaft (48) and a cylindrical body (24) that protrudes downward from the lower surface, and the cylindrical body (24) may be rotatably supported by the shaft (48). With this configuration, foreign matter is prevented from entering between the shaft (48) and the cylindrical body (24).

[0010] The guide portion (10) may include a scraper portion (50) for scraping off mud adhering to the elongated body (105a) guided by the roller portion (11). In this configuration, the elongated body (105a) guided by the guide portion (10) moves in the front-rear direction, so that mud adhering to the elongated body (105a) can be easily scraped off.

[0011] The scraper portion (50) is formed by elastic plate-like members (61, 62), and the plate-like members (61, 62) may include a central opening (51) through which the elongated body (105a) passes, a plurality of slits (52) formed radially from the central opening (51), a rib (55) formed between the plurality of slits (52), and a central slit (57) extending upward from the central opening (51) to the outer periphery of the plate-like members (61, 62). In this configuration, the plurality of slits (52) allow the vicinity of the central opening (51) of the scraper portion (50) to freely deform in accordance with the elongated body (105a). In addition, the rib (55) is provided between the slits, so that the vicinity of the central opening (51) of the scraper portion (50) has appropriate elasticity, and thus mud adhering to the elongated body (105a) can be effectively scraped off. In addition, since the inside and outside of the central opening (51) are connected via the central slit (57), the long body (105a) can be easily set in the central opening (51).

[0012] The base 40 may include a rod 42 extending vertically and buried in the ground, and a plate-shaped anti-rotation member 43 extending radially from the rod 42. In this configuration, the base 40 fixed to the ground is prevented from rotating relative to the ground. Effect of the Invention

[0013] As described above, according to one aspect of the present invention, it is possible to provide a guide device that can appropriately guide an elongated body even if the position of the elongated body changes. [Brief description of the drawings]

[0015] An example of the guide device will be described below with reference to the attached drawings. In this specification, as an example of the guide device, a guide device that guides a hose (long body) of a spray device will be described. In the following description, "upper" and "lower" are defined based on a state in which the guide device is installed on a horizontal surface such as the ground. In addition, "front" and "rear" are defined based on the hose of the spray device, with the tip side of the hose being the front and the base end side being the rear, and this definition also applies to the guide device that engages with the hose. In addition, the spray device may be a power sprayer that sprays a chemical solution (liquid) such as an agricultural chemical. The power sprayer pressure-feeds the chemical solution stored in a chemical solution tank to the hose by a pump driven by the power of an engine or the like, and sprays the chemical solution from a nozzle provided at the tip of the hose. The power sprayer may have a hose reel for winding and unwinding the hose using power.

[0016] FIG. 1 is a front view of an example of the guide device 1. FIG. 2 is a rear view of the example of the guide device 1. FIG. 3 is a perspective view of the example of the guide device 1 as viewed from the rear side. FIG. 4 is a perspective view of the example of the guide device 1 as viewed from the front side. Note that FIG. 4 illustrates the guide device 1 in a state in which a scraper, which will be described later, has been removed. As shown in FIGS. 1 to 4, the guide device 1 includes a guide portion 10 and a base portion 40.

[0017] The guide portion 10 includes a roller portion 11. The roller portion 11 is a portion that guides a hose (long body) that moves in the front-rear direction along the longitudinal direction. The roller portion 11 includes a first roller 12, a second roller 13, and a frame (bracket) 20. A pair of first rollers 12 are provided as an example. The pair of first rollers 12 are arranged apart from each other in the left-right direction so as to face each other with the hose in between. The first roller 12 is substantially cylindrical with a curved surface 12a whose center in the axial direction is recessed radially inward. The rotation axis of the first roller 12 is along the vertical direction. That is, the first roller 12 has a through hole along the vertical direction to accommodate a shaft body that serves as the rotation axis. The vertical positions of the pair of first rollers 12 are aligned with each other. In addition, the front-rear positions of the pair of first rollers 12 are aligned with each other.

[0018] The second roller 13 is located below the first roller 12 and supports the hose from below. The second roller 13 has a generally cylindrical shape with a curved surface 13a that is recessed radially inward at the center in the axial direction. For example, the first roller 12 and the second roller 13 may have the same shape. The rotation axis of the second roller 13 is along the left-right direction. That is, the rotation axis of the second roller 13 intersects (is perpendicular to) the up-down direction and the front-rear direction. In one example, the position of the second roller 13 in the up-down direction may be lower than the lower end of the first roller 12. In the illustrated example, the position of the lower end of the first roller 12 and the position of the upper end of the second roller 13 are generally the same. In addition, the position of the second roller 13 in the left-right direction may be midway between the pair of first rollers 12. In the illustrated example, the pair of first rollers 12 are separated left-right by approximately the same amount as the axial length of the second roller 13. Furthermore, the position of the second roller 13 in the front-rear direction may be the same as the positions of the pair of first rollers 12 in the front-rear direction.

[0019] The frame 20 supports the first roller 12 and the second roller 13 so as to be rotatable. In the illustrated example, the frame 20 has a first frame 21 and a second frame 31. The first frame 21 has a rectangular bottom plate portion 22 extending along the left-right direction, a front plate portion 25 standing from the front end edge of the bottom plate portion 22, and an upper plate portion 29 extending rearward from the upper end edge of the front plate portion 25. The front plate portion 25 includes a lower frame portion 26 standing uniformly from the front end edge of the bottom plate portion 22, and a pair of vertical frame portions 27 extending upward from both the left and right ends of the lower frame portion 26. A pair of upper plate portions 29 are provided on the left and right. The pair of upper plate portions 29 are connected to the upper end edges of the pair of vertical frame portions 27, respectively.

[0020] The second frame 31 has a rectangular bottom plate portion 32 that is shorter in the left-right direction than the bottom plate portion 22 of the first frame 21, a pair of side plate portions 33 that stand up from the left and right edges of the bottom plate portion 32, and an upper plate portion 39 that extends away from each other in the left-right direction from the upper edges of each of the pair of side plate portions 33.

[0021] The bottom plate portion 32 of the second frame 31 is fixed on the bottom plate portion 22 of the first frame 21. For example, the bottom plate portion 32 of the second frame 31 may be welded to the bottom plate portion 22 of the first frame 21. The pair of side plate portions 33 face each other. The pair of side plate portions 33 are separated in the left-right direction by a length substantially equal to the axial length of the second roller 13. The second roller 13 is disposed between the pair of side plate portions 33. In one example, a through hole is formed in each of the pair of side plate portions 33. The second roller 13 is rotatably supported by the bolt 13b inserted into the through hole, with the bolt 13b serving as a rotation axis.

[0022] A pair of upper plate portions 39 of the second frame 31 face a pair of upper plate portions 29 of the first frame 21, respectively. The upper plate portions 39 and 29 facing each other are vertically spaced apart by a length substantially equal to the axial length of the first roller 12. The first roller 12 is disposed between the upper plate portions 39 and 29 facing each other. In one example, a through hole is formed in each of the upper plate portions 39 and 29. The first roller 12 is rotatably supported by the bolt 12b, which is inserted through the through hole, as a rotation axis.

[0023] A gripping member 23 is provided on the bottom plate portion 22 of the first frame 21. One example of the gripping member 23 is a cylindrical member bent into a U-shape. Both longitudinal ends 23a of the gripping member 23 are fixed to the upper surface of the bottom plate portion 22 so that a longitudinal central portion of the gripping member 23 is spaced apart from the rear end edge of the bottom plate portion 22. For example, the gripping member 23 may be welded onto the bottom plate portion 22.

[0024] A friction reduction member 28 is provided on the front plate portion 25 of the first frame 21. One example of the friction reduction member 28 is a cylindrical member. The friction reduction member 28 is fixed to the upper end of the lower frame portion 26 of the front plate portion 25. For example, the friction reduction member 28 may be welded to the lower frame portion 26. The friction reduction member 28 is provided over the entire area in the left-right direction at the upper end of the lower frame portion 26. This prevents the hose moving in the front-rear direction from coming into contact with the lower frame portion 26.

[0025] A cylinder 24 protruding downward is provided on the lower surface 22a of the bottom plate portion 22 of the first frame 21. The cylinder 24 is cylindrical. The central axis of the cylinder 24 may be perpendicular to the lower surface 22a of the bottom plate portion 22. In one example, the bottom plate portion 22 of the first frame 21 has a through hole that penetrates the bottom plate portion 22 in the up-down direction. In addition, the bottom plate portion 32 of the second frame 31 has a through hole that penetrates the bottom plate portion 32 in the up-down direction. These through holes are formed at the same position when viewed from the up-down direction, and communicate with the inner space of the cylinder 24.

[0026] The base 40 supports the guide part 10 from below. The base 40 includes an embedded part 41 that is expected to be embedded in the ground when in use, and an exposed part 46 that is expected to be exposed from the ground. The embedded part 41 includes a rod 42 and an anti-rotation member 43. The rod 42 has a cylindrical shape that extends in the vertical direction. The lower end of the rod 42 is formed into a cone shape so that it can be easily embedded in the ground.

[0027] The anti-rotation member 43 has a plate shape extending radially from the rod 42. The anti-rotation member 43 in the illustrated example is formed on the upper side from the middle position in the vertical direction of the rod 42. The anti-rotation member 43 has a triangular shape that widens toward the upper side. An upper plate portion 45 extending in one of the left and right directions is formed at the upper end of the anti-rotation member 43. A through hole 45a is formed in the upper plate portion 45.

[0028] The exposed portion 46 has a contact body 47 that contacts the ground surface when the buried portion 41 is buried in the ground. The contact body 47 is plate-shaped. The contact body 47 in the illustrated example is disk-shaped. The upper end of the rod 42 is connected to the center of the disk-shaped contact body 47. In addition, the upper plate portion 45 of the rotation prevention member 43 may be welded to the contact body 47.

[0029] An axis body 48 is formed on the upper surface of the abutment body 47 so as to protrude upward along the cylinder body 24 which is the rotation axis of the guide part 10. In one example, the axis body 48 may be formed integrally with the rod 42. The axis body 48 is inserted into the inside of the cylinder body 24 which protrudes downward from the bottom plate part 22 of the first frame 21. As a result, the cylinder body 24 is supported by the axis body 48 so as to be rotatable around the axis of the axis body 48. In one example, the outer diameter of the lower end part 48a of the axis body 48 is formed larger than the inner diameter of the cylinder body 24, so that the cylinder body 24 is supported by the axis body 48. Since the bottom plate part 22 extends so as to be perpendicular (intersect) with the extending direction of the axis body 48, the bottom plate part 22 can rotate while maintaining a parallel state with respect to the abutment body 47. In this way, the guide part 10 is provided so as to be rotatable with respect to the base part 40. In the illustrated example, the upper end of the shaft 48 is exposed from the through hole in the bottom plate portion 32 of the second frame 31, and this exposed shaft 48 is provided with a retaining member 49 such as a retaining ring or a nut (see Figure 3).

[0030] The guide portion 10 includes a scraper portion 50 for scraping off mud adhering to the hose guided by the roller portion 11. The scraper portion 50 is formed of an elastic plate-like member. Examples of materials constituting the scraper portion 50 include rubber and the like. An example of the scraper portion 50 is composed of a first plate-like member 61 and a second plate-like member 62. The first plate-like member 61 and the second plate-like member 62 are fixed to the front surfaces of the pair of vertical frame portions 27. In the illustrated example, each of the pair of vertical frame portions 27 is provided with a plurality of bolt holes 27a (two in the illustrated example) penetrating in the front-rear direction (see FIG. 4). The first plate-like member 61 and the second plate-like member 62 are also provided with bolt holes 63a at positions corresponding to the bolt holes 27a. The first plate-like member 61 and the second plate-like member 62 are fixed to the front surfaces of the pair of vertical frame portions 27 by fastening members 63 such as bolts and nuts.

[0031] The scraper portion 50 has a central opening 51, a plurality of slits 52, a plurality of ribs 55, and a central slit 57. The central opening 51 is a portion through which a hose moving in the front-rear direction passes. In one example, the central opening 51 is formed by combining a semicircular cutout portion formed in the first plate-like member 61 and a semicircular cutout portion formed in the second plate-like member 62. The central opening 51 is disposed at the center of the scraper portion 50 in the left-right direction and below the center in the up-down direction. As a result, the position of the central opening 51 coincides with the position of the second roller 13 when viewed from the front-rear direction. In the illustrated example, the upper curved surface 13a of the second roller 13 is contained inside the central opening 51 when viewed from the front-rear direction so that the hose on the second roller 13 can pass through the central opening 51 with almost no bending. The diameter of the central opening 51 may be approximately the same as the outer diameter of the hose expected to be used.

[0032] The plurality of slits 52 are formed radially from the central opening 51. In one example, the first plate-shaped member 61 and the second plate-shaped member 62 are similarly formed with the plurality of slits 52. The plurality of slits 52 are formed at approximately equal intervals in the circumferential direction. For example, the plurality of slits 52 include a slit 52a extending along the left-right direction, a slit 52b formed above the slit 52a, and a slit 52c formed below the slit 52a. The length of the upper slit 52b is longer than the slit 52a, and the length of the lower slit 52c is shorter than the slit 52a. When the central opening 51 is taken as the base end, the tip of the slit 52 may be circular. In the illustrated example, the first plate-shaped member 61 and the second plate-shaped member 62 each have one slit 52a. The first plate-shaped member 61 and the second plate-shaped member 62 each have three slits 52b. The first plate-shaped member 61 and the second plate-shaped member 62 each have three slits 52c.

[0033] The central slit 57 extends from the central opening 51 upward to the outer periphery of the plate-shaped member (scraper portion 50). As described above, the scraper portion 50 in one example is composed of the first plate-shaped member 61 and the second plate-shaped member 62. In this case, the central slit 57 may be a gap formed between the first plate-shaped member 61 and the second plate-shaped member 62. When the first plate-shaped member 61 and the second plate-shaped member 62 are in contact with each other, the contact point becomes the central slit 57. When viewed from the front-rear direction, the first roller 12 and the second roller 13 are not arranged at the position where the central slit 57 is formed. When viewed from the front-rear direction, the pair of first rollers 12 are arranged to sandwich the central slit 57, and the second roller 13 is arranged below the central slit 57. Thus, in one example, a member extending to intersect with the central slit 57 is not provided. In the illustrated example, a slit 58 is also formed extending downward from the central opening 51 to the outer periphery of the plate-like member, but for example, when the first plate-like member 61 and the second plate-like member 62 are fixed to the first frame 21 upside down, this slit 58 functions as a central slit. In this case, the height position of the central opening 51 may overlap the height position of the curved surface 12a of the first roller 12.

[0034] The ribs 55 are formed between the slits 52. The ribs 55 are formed radially from the vicinity of the central opening 51. The ribs 55 may be formed radially from the central opening 51 as a base end. For example, the ribs 55 are formed along the radial direction so as to bisect the angle between the slits 52 adjacent in the circumferential direction. In one example, a rib 55 is also formed between the central slit 57 and the adjacent slit 52. That is, the slits 52 are formed between the adjacent ribs 55. In the illustrated example, eight ribs 55 and seven slits 52 located between the ribs 55 are formed in each of the first plate-shaped member 61 and the second plate-shaped member 62. The lengths of the ribs 55 may be the same as each other. In one example, the length of the rib 55 is longer than the lower slit 52c and shorter than the left and right slits 52a. As shown in FIG. 1 and FIG. 2, the ribs 55 are formed on both the front and rear surfaces of the scraper portion 50.

[0035] 5 and 6 are schematic diagrams for explaining an example of a method of using the guide device 1. The example of Fig. 5 and Fig. 6 shows a state in which a liquid medicine such as a pesticide is sprayed on agricultural crops in a farm field, and shows ridges 101 which are the medium on which the agricultural crops are grown, and furrows 103 between the ridges 101 which are passages along which workers can walk. Also shown in this example are a power sprayer 105, a hose 105a extending from the power sprayer 105, and a guide device 1 which guides the hose 105a. The hose 105a of the power sprayer 105 can be wound up and unwound by a hose reel provided on the power sprayer 105.

[0036] In one example, an operator sprays a chemical solution from a spray nozzle provided at the tip of a hose 105a of a power sprayer 105. The operator sprays a chemical solution or the like on crops while moving through the furrow 103 with the tip of the hose 105a in hand. The hose 105a extending from the power sprayer 105 is attached to the guide device 1 so that it can be guided by the guide device 1. For example, an operator places the guide device 1 at an arbitrary location in a field before starting spraying work. In the illustrated example, the guide device 1 is placed between the power sprayer 105 and the entrance of the furrow 103a, and near the entrance of another furrow 103b. An operator can fix the guide device 1 to the field by sticking the buried part 41 of the guide device 1 into the field. An operator may stick the buried part 41 into the field until the abutment body 47 of the guide device 1 abuts against the surface of the field. When the buried portion 41 is buried in the field, an operator may drive a fixing peg or the like into the through hole 45a of the rotation prevention member 43.

[0037] After the guide device 1 is installed in the field, the operator attaches the hose 105a to the guide device 1. For example, the operator can pass the hose 105a through the central opening 51 of the scraper unit 50 of the guide device 1 via the central slit 57 formed in the scraper unit 50. The hose 105a is guided by the guide device 1 so that the position where the hose 105a passes through the central opening 51 is closer to the tip side than the position where the hose 105a passes through the roller unit 11. That is, when the hose 105a is unwound, the hose 105a moves from the roller unit 11 toward the central opening 51, and when the hose 105a is wound up, the hose 105a moves from the central opening 51 toward the roller unit 11.

[0038] Once the hose 105a is set, the worker sprays the crops with a chemical solution or the like while moving between the furrows 103 with the hose 105a in hand. In the example of FIG. 5, the power sprayer 105, the guide device 1A, and the tip of the hose 105a are aligned in a substantially straight line. In this case, the hose 105a is supported by the second roller 13 and also by the scraper unit 50. Next, as shown in FIG. 6, when the worker moves to the adjacent furrow 103b, the worker has the hose 105a supported by another guide device 1B at a position on the tip side of the portion supported by the guide device 1.

[0039] In the example of FIG. 6, the hose 105a is curved at the position of the guide device 1. In this case, the guide unit 10 of the guide device 1 can rotate with respect to the base 40 so that the front of the guide device 1 coincides with the bending direction of the hose 105a. That is, in the first guide device 1A, the tip side of the hose 105a is curved toward the direction D1, so the guide unit 10 rotates so that the scraper unit 50 provided at the front of the guide unit 10 faces the direction D1. In the second guide device 1B, the hose 105a is curved toward the direction D2, so the guide unit 10 rotates so that the scraper unit 50 provided at the front of the guide unit 10 faces the direction D2. When the spraying of the chemical solution or the like is completed, the worker operates the hose reel of the power sprayer 105 to wind up the hose 105a. The wound hose 105a moves toward the base end side (the power sprayer 105 side). When the hose 105a passes through the central opening 51 of the scraper portion 50, the hose 105a enters the central opening 51 so as to be substantially perpendicular to the plate-shaped scraper portion 50. At this time, dirt and other deposits adhering to the peripheral surface of the hose 105a are scraped off by the scraper portion 50.

[0040] After the work is completed, the worker pulls out the guide device 1 from the field. For example, the worker may grip the gripping member 23 to pull out the guide device 1. Alternatively, the worker may tie a rope or the like to the through hole 45a of the rotation prevention member 43 and pull the rope to pull out the guide device 1.

[0041] As described above, the example guide device 1 includes a guide portion 10 including a roller portion 11 that guides a hose 105a that moves back and forth along the longitudinal direction, and a base portion 40 that supports the guide portion 10 from below, and the guide portion 10 is arranged to be freely rotatable relative to the base portion 40.

[0042] In the above-described guide device 1, the hose 105a moves in the front-rear direction while being guided by the roller portion 11 of the guide portion 10. In this case, even if the position of the hose 105a changes in the left-right direction, for example, the guide portion 10 rotates following the position of the hose 105a because the guide portion 10 is provided rotatably with respect to the base portion 40. Therefore, the roller portion 11 and the hose 105a can easily form an appropriate positional relationship. Therefore, the hose 105a can be appropriately guided.

[0043] The roller unit 11 may include a pair of first rollers 12 facing each other with the hose 105a therebetween, a second roller 13 positioned below the first roller 12 and supporting the hose 105a from below, and a frame 20 rotatably supporting the first roller 12 and the second roller 13. In this configuration, when the direction of the hose 105a changes left and right at the position of the guide device 1, the hose 105a is guided by the first roller 12. When the direction of the hose 105a does not change left and right at the position of the guide device 1, that is, when the hose 105a is guided linearly by the guide unit 10, the hose 105a is guided by the second roller 13. Since rollers are provided on the left, right, and bottom of the hose 105a, the hose 105a is guided by any one of the rollers.

[0044] The base 40 includes a shaft 48 that protrudes upward along the rotation axis of the guide part 10, and the frame 20 includes a lower surface 22a that extends so as to intersect with the extending direction of the shaft 48, and a cylindrical body 24 that protrudes downward from the lower surface 22a, and the cylindrical body 24 may be rotatably supported by the shaft 48. In this configuration, entry of foreign matter between the shaft 48 and the cylindrical body 24 is suppressed.

[0045] The guide portion 10 may include a scraper portion 50 for scraping off mud adhering to the hose 105a guided by the roller portion 11. In this configuration, the hose 105a guided by the guide portion 10 moves in the front-rear direction, so that mud adhering to the hose 105a can be easily scraped off.

[0046] The scraper part 50 is formed by a plate-like member having elasticity, and the plate-like member may include a central opening 51 through which the hose 105a passes, a plurality of slits 52 formed radially from the central opening 51, a rib 55 formed between the plurality of slits 52, and a central slit 57 extending upward from the central opening 51 to the outer periphery of the plate-like member. In this configuration, since the plurality of slits 52 are provided, the vicinity of the central opening 51 of the scraper part 50 is easily deformed according to the hose 105a. In addition, since the rib 55 formed to be partially thick is provided between the slits 52, the vicinity of the central opening 51 of the scraper part 50 has appropriate elasticity, and the mud adhering to the hose 105a can be effectively scraped off. In addition, since the inside and outside of the central opening 51 are connected via the central slit 57, the hose 105a can be easily set in the central opening 51.

[0047] Moreover, the length of the slits 52c formed on the lower side is shorter than the length of the rib 55. By reinforcing the area between the lower slits 52c, where stress from the hose 105a is likely to be applied, with the rib 55, the lower portion of the central opening 51 is prevented from bending excessively.

[0048] The base 40 may include a rod 42 extending in the vertical direction and buried in the ground, and a plate-shaped anti-rotation member 43 extending in the radial direction from the rod 42. In this configuration, the base 40 fixed to the ground is prevented from rotating.

[0049] Although the embodiment of the present invention has been described above, the specific form of the present invention is not limited to the above example.

[0050] For example, the base is illustrated as having a rod buried in the ground, but the base only needs to have a function for positioning the guide device at an arbitrary position. Therefore, in other examples, the base may be a mounting part placed on the ground surface. For example, the base may be configured by a block (weight) made of metal, concrete, etc. In this case, the base placed on the ground surface can be positioned at the position where it is placed by its own weight. In this way, the guide device can be positioned not only in farm fields, but also on ground laid with gravel, tiles, etc., ground paved with asphalt, concrete, etc., and can be used, for example, to guide a hose for cleaning solar panels, aircraft, ships, etc. [Explanation of symbols]
