Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spray hose mounting structure for a power sprayer in which a spray hose extending from a drug tank can be mounted so as not to sag.

[0002]

2. Description of the Related Art Conventionally, as seen in Japanese Patent Application No. 2-126445 filed by the applicant of the present invention, a spray pipe which can be attached to a medicine tank is connected to a pump in the medicine tank. In the power sprayer, the spray hose extending from the drug tank is straight and long so as to improve workability.

[0003]

[Problems to be Solved by the Invention] However, when the spray pipe is attached to the drug tank for storage, the spray hose greatly hangs or sags, which is a hindrance to the treatment at the time of storage. Depending on the posture at the time of work, there was a problem that the workability was poor because the spray hose got in the way, and it got caught in plants and the like.

[0004]

SUMMARY OF THE INVENTION The present invention has been devised to solve such a problem and has a simple structure so that it can be suitably implemented. Therefore, the present invention is located below the portion where the spray pipe is mounted. On the side of the medicine tank, a guide body having a circular cross section is installed around the lower horizontal axis as a pivoting function.
Both ends of a long coil-shaped spray hose that can be fitted into the guide body while being restored to a coil shape and shrinking are connected to the pump in the medicine tank and the spray pipe, respectively.

[0005]

Therefore, when the spray pipe is mounted on the medicine tank and stored therein, the entire coil-shaped spray hose is restored to the guide body in a coil shape and is fitted while shrinking, so that the slackened as in the conventional case. It will be satisfactorily stored without doing, and at the time of work, while rotating the guide body in the direction of the spraying posture, the coil-shaped spray hose pulled out by the spray pipe is smoothly extended from the guide body, Since it is possible to follow the spray pipe side without sagging, it is possible to perform the control work with good workability.

EXAMPLE FIG. 1 is a side view of a backpack type power sprayer. A cap 5 is attached to the upper part of a drug tank A formed by blow molding a synthetic resin material, and the upper part on the back side of the drug tank A is covered. The attached hook 6 and the attachment holes 7 formed on both sides of the lower back side are connected to the upper and lower ends of both shoulder straps 8 and 8, respectively, and the backrest 10 is detachably attached by screws 9 at four corners. And the ventilation grooves 11 and 11 on the opening side
A recess 12 communicating with the medicine tank A is formed in the lower inner part of the medicine tank A. A battery 13 and a motor 14 are provided inside the recess 12 and the medicine tank A is directly connected to the pump 1 directly below the motor 14. To the bottom of the strainer 1
5 is extended, and a locking piece 16 is provided on the lateral side portion of the medicine tank A, which can vertically lock the spray pipe B and can be detachably locked.

A round bar-shaped guide whose upper end 2a is frustoconical and whose cross section is circular is laterally lateral to the lower part of the medicine tank A below the portion where the spray pipe B is engaged. Body 2
It is rotatably installed around the lower horizontal shaft 3 projecting from the medicine tank A, and has a light spring force so that the guide body 2 can be fitted into the outer periphery of the guide body 2 while being restored in a coil shape and shrinking. Both ends of the long coil-shaped spray hose 4 are connected to the base side of the grip portion 17 of the spray pipe B and the discharge side of the pump 1, respectively, and one end of a plate body 18 extended from the lower portion of the guide body 2. Horizontal weak tension spring 19 on the side
The guide body 2 can be urged and biased so that the guide body 2 is erected upright, but the guide body 2 can also be configured to return to the erected state by using another elastic force means.

FIG. 4 shows another embodiment of the present invention, which is substantially the same as the above-described embodiment as indicated by the same reference numeral, but the guide member 2
Is formed in a cylindrical shape whose upper end portion 2b is largely opened and has a circular cross section, and the coiled spray hose 4 is configured to be restored into a coil shape and can be fitted while shrinking. .

Therefore, as shown in FIGS. 1 and 2, when the spray pipe B is mounted on the locking piece 16 and stored, the coil is attached to the guide body 2 which is in an upright state by pulling the tension spring 19. Since the entire spray hose 4 is restored to a coil shape and is fitted while shrinking, the spray hose 4 can be favorably stored without sagging as in the conventional case. Is removed from the locking piece 16 and directed to the work position as shown by the phantom line in FIG. 1,
The guide body 2 resists the elastic force, and in the direction thereof, the guide body 2 is rotated about the horizontal axis 3 and tilted as shown by the arrow a.
Coil type spray hose 4 pulled out by spray pipe B
Can be smoothly extended from the guide body 2 as it is and can follow the spray pipe B without sagging. Furthermore, when the spray pipe B is brought closer to the guide body 2 at the end of the work, the coil-shaped spray hose 4 contracts. While being restored to a coil shape and fitted into the guide body 2, the tension spring 19
While raising the guide body 2 by pulling on the spray pipe B
Can be stored by being locked to the locking piece 16.

[0010]

As described above, according to the present invention, when the spray pipe B is mounted on the medicine tank A for storage or transportation,
Since the coil-shaped spray hose 4 is fitted into the guide body 2 while shrinking into a coil shape, the coil-shaped spray hose 4 can be stored well without being slackened and exposed as in the conventional case without disturbing. Therefore, at the time of work, the coil-shaped spray hose 4 pulled by the spray pipe B can be smoothly extended from the guide body 2 while rotating the guide body 2 in the direction of the spray posture, so that the spray pipe B side without sagging. Therefore, it is possible to perform pest control work with good workability without sagging and getting in the way as in the past and getting caught in plants, etc., and it is preferable to have a simple structure. It has features that can be implemented.
