Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a hose guide that allows for smooth movement of a hose when controlling pests or irrigation in a farm or the like.

``Prior Art'' Conventionally, various hose guides have been devised and used to move hoses smoothly.
All of these had drawbacks in that the resistance when moving the hose was large, and the hose easily came off from the hose guide.

``Purpose of the present invention'' In view of the above-mentioned drawbacks of the conventional technology, the present invention has been developed to create a system that has low resistance when the hose moves in any direction, and that prevents the hose from falling off or getting wedged between the rollers when moving the hose. To provide a hose guide which can efficiently prevent the occurrence of damage, and also allows easy installation of rollers and replacement of worn and damaged rollers.

"Means for Achieving the Object of the Present Invention" The present invention includes a support whose lower part can be inserted into the soil and fixed therein, a ring-shaped shaft having a notch at the upper end fixed to the upper part of the support, A large number of rollers are inserted into the notch of the shaft so that the side surface of the inner part contacts the adjacent side surface over almost the entire surface of the shaft, and can guide a rotatably attached hose. The present invention is characterized in that it includes a falling-off prevention metal fitting such as a cap nut attached to the end of the shaft to prevent a large number of rollers from falling off the shaft.

"Embodiments of the present invention" The present invention will be described in detail below with reference to embodiments shown in the drawings.

In the embodiments shown in Figures 1 to 5, reference numeral 1 denotes a support made of a metal material or the like whose lower part can be inserted into the soil and fixed. A strut body 2, a ring-shaped shaft mounting bracket 4 of an upper end opening 3 whose lower surface at an approximately central portion is fixed to the upper part of the strut body 2 by welding or the like, and a position near the upper end of the strut body 2. reinforcing members 5, 5 fixed by welding or the like to a position near the bottom of the shaft mounting bracket 4; and a shaft support member 7 on which a shaft support portion 6 is formed.

Reference numeral 8 denotes a ring-shaped shaft fixed to the upper part of the support column 1, and male screws 9, 9 are formed at both open ends of the upper part of the shaft 8, and support parts 10, 10 at both ends of the shaft mounting bracket 4 are formed. are inserted into the insertion holes 11, 11 of.

Further, the lower portion of the shaft 8, which is approximately the center thereof, is supported by the shaft support portion 6 of the shaft support member 7.

12, 12 are male screws 9, 9 at both ends of the shaft 8.
This is a cap nut that serves as a fall-preventing metal fitting that screws together with the shaft 8 to fix the shaft 8 to the support 1.

Reference numeral 13 denotes a plurality of rollers capable of guiding a hose 14 rotatably attached to the shaft 8 over substantially the entire surface of the shaft 8;
3 has each roller 13 on the inner part of the shaft 8.
are arranged so that there are no gaps between the two sides.

As shown in FIGS. 6 and 7, the hose guide 15 having the above structure is fixed by inserting the support 1 into the soil at a position in the farm 16 where the direction of the hose is to be changed. Thereafter, the hose 14 pulled out from the pump, pest control device 17, etc. is passed through the roller 13 and pulled out. As a result, no matter which direction the hose 14 is pulled out,
The hose 14 comes into contact with one of the rollers 13 attached to the ring-shaped shaft 8 and can move smoothly.

"Different Embodiments of the Present Invention" Next, different embodiments of the present invention shown in FIGS. 8 to 19 will be described. In the description of these embodiments, the same components as those of the embodiments of the present invention will be designated by the same reference numerals and redundant explanations will be omitted.

In the embodiment shown in FIGS. 8 and 9, the main difference from the embodiment of the present invention is the support 1A. The hose guide 15A may be configured in this manner in that the footrest member 18 is fixed by welding or the like so that the hose guide 15A can be inserted by placing the foot on it.

The embodiment shown in FIGS. 10 to 15 is mainly different from the embodiment of the present invention in that the substantially central lower end of the ring-shaped shaft 8 is fixed to the upper end of the column 1B by welding or the like. C-shaped stoppers 12 are attached to both ends of the ring-shaped shaft 8 to prevent them from falling off.
By attaching A and 12A, similar effects can be obtained even if the hose guide 15B is configured in this way.

The main difference between the embodiment shown in FIGS. 16 and 17 and the embodiment shown in FIGS. 10 to 15 is that fittings 19 for preventing the hose 14 from coming off are attached to both ends of the ring-shaped shaft 8. By configuring the hose guide 15C in this way, it is possible to reliably prevent the hose 14 from coming off. The retaining fitting 19 includes an arc-shaped retaining fitting body 20 and a shaft insertion hole 2 formed at both ends of the retaining fitting body 20 by bending in a substantially right angle direction.
1 is formed from mounting pieces 22, 22, respectively.

Furthermore, as shown in FIGS. 18 and 19,
The retaining fitting 19A may be formed in the shape of a lock fitting to open and close the opening of the shaft 8 so that the hose 14 having a smaller diameter can be attached or removed from the opening.

"Effects of the Present Invention" As is clear from the above explanation, the present invention has the following effects.

(1) A ring-shaped shaft fixed to the upper part of the support, with the side surface of the inner part touching the adjacent side surface over almost the entire surface of the shaft, and capable of guiding a rotatably attached hose. Since the hose is equipped with two rollers, even if the hose inserted into the roller is pulled in any direction, it will surely come into contact with the roller and guide the hose smoothly. Therefore, the hose can be moved easily. Therefore, pest control work and irrigation work using a hose can be easily performed.

(2) Due to (1) above, the structure is simple, so it can be manufactured at relatively low cost.

(3) According to (1) above, since the shaft on which the roller is rotatably mounted is formed in a ring shape, the hose inserted into the roller is moved from the horizontal axis of the ring-shaped shaft when the hose is moved. Since the diameter of the upper portion gradually decreases, the hose is located near the horizontal shaft center portion and below the vicinity, and it is possible to efficiently prevent the hose from falling off from the upper notch of the shaft.

(4) When installing multiple rollers on a ring-shaped shaft, simply insert the rollers through the notch at the top of the ring-shaped shaft and attach fall-prevention fittings such as cap nuts to both ends of the shaft. is completed.

Therefore, as in the past, after attaching a roller to a shaft, the shaft is attached to a frame by welding, etc., or after attaching a roller to a shaft, and then bending the end of the shaft, which is a labor-intensive manufacturing process. It is not necessary to do this.

Furthermore, worn and damaged rollers can be easily replaced.

(5) The inner side surface of the ring-shaped shaft is in contact with the adjacent side surface over almost the entire surface of the ring-shaped shaft, and multiple rollers are rotatably attached to the ring-shaped shaft. This can prevent the hose from getting wedged between the rollers, damaging the hose, or providing resistance to the rollers that would prevent them from rotating smoothly.
