Abstract

(57) [Summary] [Purpose] To enable the installation of a spray hose interposed between the pump and the spray pipe in a drug tank in a power sprayer so that it does not become sagging and exposed. [Structure] In a power sprayer configured by connecting a spray pipe B that can be attached to a drug tank A and connected to a pump 1 in the drug tank A, the drug tank is located below the part to which the spray pipe B is attached. On the side of A, a guide body 2 having a circular cross section is installed so as to be able to rotate around the lower horizontal axis 3, and the guide body 2 restores almost the entire body to a coil shape while contracting. Both ends of a long coiled spray hose 4 that can be fitted are connected to the pump 1 and the spray pipe B, respectively.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is installed so that the spray hose extending from the chemical tank does not become loose. This invention relates to a spray hose attachment structure for a power sprayer that can be used.

0002

[Conventional technology]

Conventionally, as seen in Utility Model Application No. 12645, filed by the present applicant, A spray pipe that can be attached to a drug tank is connected to a pump inside the drug tank. In power sprayers, the spray hose that extends from the chemical tank is designed to improve workability. It was straight and long.

0003

[Problem that the idea aims to solve]

However, when storing the spray pipe attached to the drug tank, the spray hose If it hangs down or sag, it gets in the way or is difficult to deal with when storing it. Also, depending on your posture when working, the spray hose may become sagging and get in the way, or it may get caught in the way of vegetation. This caused problems such as getting stuck in the grooves and poor workability.

0004

[Means to solve the problem]

The present invention solves such problems and has a simple structure that can be implemented suitably. Therefore, the drug tank, which is below the part where the spray tube is attached, has been devised. A guide body with a circular cross section is installed on the side of the rack for rotation around the lower horizontal axis. A long piece that can be installed and fitted to the guide body while restoring almost the entire body into a coiled shape and shrinking. Connect both ends of the coiled spray hose to the pump in the drug tank and the spray pipe, respectively. It is constructed by communicating with each other.

[0005]

[Effect]

Therefore, when storing the spray tube by attaching it to a drug tank, use a coil-shaped spray tube. The entire hose is restored to the guide body in a coiled shape and is fitted while shrinking, unlike the conventional method. It will be stored well without sagging, and when working, While rotating the guide body in the direction of the spraying position, Extend the oil-shaped spray hose smoothly from the guide body to ensure that the spray tube does not sag. This means that it can be made to follow the side, making it possible to perform pest control work with good work efficiency. Wear.

【Example】

Figure 1 shows a side view of a backpack-type power sprayer, which is formed by blow molding synthetic resin material. A cap 5 is attached to the upper part of the drug tank A, and a cap 5 is attached to the upper part of the back side of the drug tank A. Both backpack straps are attached to the attached hook 6 and both mounting holes 7, 7 formed on both sides of the lower part of the back side. Connect the top and bottom ends of heads 8 and 8, respectively, and attach them removably using screws 9 at the four corners. A recess 12 that opens on the side of the backrest 10 and communicates with the ventilation grooves 11, 11 on the opening side. is formed at the inner lower part of the drug tank A, and a battery 13 and a battery 13 are formed inside the recess 12. and a motor 14, and from the pump 1 directly connected below the motor 14. A strainer 15 is installed on the bottom of the drug tank A, and a strainer 15 is installed on the side of the drug tank A. A locking piece 16 is provided protrudingly to allow the spray pipe B to be vertically locked and detachably locked. The structure is similar to the conventional structure.

[0007] An upper A round rod-shaped guide body 2 whose end portion 2a has a truncated cone shape and whose cross section is circular is inserted into the drug. The guide body is installed rotatably around a lower horizontal shaft 3 protruding from the tank A. A light spring force is applied to the outer periphery of 2 so that almost the whole part is restored to a coil shape and can be inserted while shrinking. Both ends of the long coiled spray hose 4 with The base side and the discharge side of the pump 1 are connected to each other, and the lower part of the guide body 2 is connected to the discharge side of the pump 1. A weak horizontal tension spring 19 is connected to one end of the plate 18 extending from the side to provide a guide. Although the body 2 is configured to be elastically biased to stand up, it is not possible to guide it using other pressure means. It is also possible to configure the body 2 to return to the standing position.

[0008] FIG. 4 shows another embodiment, which has substantially the same structure as the previous embodiment as indicated by the same reference numerals. However, the guide body 2 has a cylindrical shape with a large opening at the upper end 2b and a circular cross section. The coiled spray hose 4 is restored to a coiled shape inside the cylinder. It is configured so that it can be fitted while shrinking.

[0009] Therefore, as shown in FIGS. 1 and 2, the spray pipe B is engaged with the locking piece 16. When storing the guide body 2, the tension spring 19 pulls the guide body 2 into an upright state. In this case, the entire coiled spray hose 4 is restored to a coiled shape and is then fitted while shrinking. As a result, it can be stored well without sagging like in the past. Also, during work, the spray tube B is removed from the locking piece 16, as shown by the phantom line in FIG. When the guide body 2 is oriented in the working position as shown in FIG. It will rotate and tilt as shown by arrow A, and will be pulled by spray pipe B. The coiled spray hose 4 that is slid out extends smoothly from the guide body 2. This allows the spray pipe to follow the B side without sagging, and the work is completed. Sometimes, when the spray tube B is brought closer to the guide body 2, the coiled spray hose 4 may shrink. It is restored into a coil shape and fitted into the guide body 2, and the tension spring 19 is pulled. While the guide body 2 is erected by tension, the spray pipe B can be locked to the locking piece 16 and stored. I will be able to do it.

0010

[Effect of the idea]

In this way, the present invention allows the spray tube B to be attached to the drug tank A for storage or for transportation. When transporting, almost the entire coiled spray hose 4 is shrunk into a coil while being guided. It will be fitted to body 2, and it will sag and get in the way as before. This means that it can be stored well without any problems, and when working, there is no need to spray. While rotating the guide body 2 in the direction of the posture, the coiled spray is pulled by the spray tube B. Smoothly extend the fog hose 4 from the guide body 2 and attach it to the spray pipe B side without sagging. This means that it can be made to follow the flow of the material, which prevents it from sagging and getting in the way like in the past. To perform pest control work with good workability without getting caught in plants or plants. It has the advantage that it can be implemented conveniently with a simple structure.
