Description

[Detailed description of the invention] [Industrial application field] This invention relates to a fuel tank for a power working machine such as a backpack power spreader.

[Prior Art] In a conventional fuel tank of this kind, as shown in FIGS. 12 and 13 showing an example of a backpack-powered spreader, fuel is stored in a container-shaped tank body a in which the fuel is stored. An inlet b is formed to be inserted into the tank body a, and a conduit member c extending outward is formed integrally with the tank body a at the inlet b, making it easy to inject fuel into the tank body a. (Illustrated in Figure 12). Note that d is a drug tank.

[Problems to be Solved by the Invention] However, in the conventional fuel tank, as described above, the conduit member c is fixed in an outwardly extended state, so that power work to equip this fuel tank is difficult. When packing the machine, the packaging box becomes relatively large and, for example, in the form shown in Fig. 13,
When lifting this power working machine, there is a risk that the conduit member c may be grasped and the fuel tank holder etc. may be bent or damaged. Further, in the form shown in FIG. 12, since the pipe line member c is integrally fixed to the tank body a, the inlet b
Generally speaking, when using a float-type cab for the engine e in backpack-type power working machines due to the need for compactness, there is less freedom in designing the position of the
It is necessary to set the fuel tank main body a above the engine e, but in such a case, spilled fuel will splash onto the high temperature parts of the engine e, which is dangerous, and it is necessary to forcefully inject the fuel. However, there are problems such as the fuel injection work being extremely troublesome.

[Means for solving the problem] This invention was created in view of the above-mentioned circumstances, and it forms a liquid feeding port in the container-shaped tank body to supply fuel to the power working machine, and also forming an inlet through which fuel can be injected; the inlet is provided with storage means; a conduit member extending outwardly from the inlet; and an opening/closing cap is provided at the open end of the conduit member. This invention proposes a removably installed fuel tank for a power working machine.

[Function] The fuel tank of this invention having the above-mentioned structure can be packed smaller, can protect the fuel tank, and can be filled with fuel more easily.

[Example] An example of this invention will be described below based on the accompanying drawings.

Figures 1, 2, and 3 are a partial rear view, a partial side view, and a partial cross-sectional view of a backpack power spreader, which is a power working machine equipped with the fuel tank of this invention. This is a partially sectional view. In the figure, 1 is a container-shaped tank body capable of containing fuel, and this tank body 1 is installed through a mounting hole 3 formed in a concave step 2 formed in the center part. It is fixed to the main body 5 of the backpack power spreader by means of mounting screws 4. Further, the tank body 1 has a liquid feeding port 6 formed at the bottom thereof for supplying fuel to an engine serving as a driving means. An inlet 7 for injecting fuel into the tank body 1 is formed above the tank body 1 . Entrance 7
In this case, a male threaded portion 8 serving as a storage means is extended in the lateral direction, and a cylindrical socket 9 can be connected to the male threaded portion 8 with a screw. A locking portion 10 that protrudes from the
is formed. When the proximal end opening of a conduit member 11 consisting of a tubular body formed into a substantially L-shape is inserted into the inside of the male threaded portion 8, and the socket 9 is attached,
A flange 12 protruding outward from the proximal opening is locked to the locking part 10, and the flange 12 and the male threaded part 8 are connected to each other.
By interposing the packing 13 between the pipe member 11 and the distal end portion of the pipe member 11, the conduit member 11 is rotatably connected to the male threaded portion 8 in a water-tight manner. Also, the pipe member 11
A male threaded portion 14 is formed at the tip opening of the cap 14, and a cap 15 capable of opening and closing the opening is screwed to the male threaded portion 14 via a strainer 16. The conduit member 11 can be projected outward by rotating the socket 9, or can be stored along the main body of the backpack power spreader (as shown in the second figure). Note that 17 is the chemical tank of the backpack-powered sprayer.

As shown in FIGS. 4 and 5, when the male threaded portion 8 formed at the inlet 7 is extended upward, the conduit member 11 may be formed into a crank shape. The pipe member 11 is made rotatable by increasing the thickness of the flange 12 formed at the proximal opening of the pipe member 11 and by interposing an O-ring 18 in place of the gasket 13. Furthermore, it is also possible to form an arm portion 19 in which the distal end portion of the conduit member 11 can be detachably held and stored by elastic force in the recess 20 of the drug tank 17 of the backpack-powered sprayer. In this case, when storing the conduit member 11, it can be reliably held and stored in the arm portion 19 by rotating into the recess 20.

As shown in FIGS. 6 and 7, the base of the conduit member 11 can be inserted into and removed from the male threaded portion 8 of the inlet 7, and is formed on the inner surface of the male threaded portion 8 instead of the gasket 13. A caulking member 2 having a plurality of tapered claws 22 that come into contact with a tapered surface 21
3 and by tightening the socket 9, insertion and removal of the conduit member 11 can be fixed at any position. A funnel 24 is provided at the tip opening of this conduit member 11.
A female threaded portion 25 is formed, and a cap 26 that can open and close the distal end opening is screwed to the female threaded portion 25. In this case, the pipe member 11 can be stored by loosening the socket 9, inserting the pipe member 11 into the tank body 1 from the inlet 7, and tightening the socket 9 again. When injecting fuel into the tank,
The conduit member 11 may be extended by the reverse operation,
In this case, since the funnel 24 is formed, it is easier to inject the fuel.

As shown in FIGS. 8 and 9, the pipe member 11 can be shaped like a bellows, and can be expanded and contracted and swung as shown by the arrows in FIG. It can also be stored along the tank body 1. In this case, the conduit member 11 is formed integrally with the inlet 7 of the tank body 1.

10 and 11, the conduit member 11 is a flexible hose, and the proximal end of the conduit member 11 is a flange portion 27 formed at the inlet 7.
The pipe member 11 is fitted from the outside and removably tightened by a band member 28, and a male thread member 29 is fitted inward to the tip opening of the conduit member 11, and an arm-shaped convex portion is provided on the outer edge. The strainer 1 is removably attached to the band member 30, and the male threaded portion 30 has a strainer 1.
A cap 15 to which the distal end opening of the conduit member 11 can be opened and closed is screwed through the cap 6 . By bending the distal end of the conduit member 11, it is removably held by an arm portion 31, which is substantially similar to the arm portion 19 shown in FIG. 11 can be stored.

[Effect of the invention] Since the fuel tank of the power working machine according to this invention is as described above, when packing, the pipe member is rotated or contracted in the direction along the main body of the power working machine, etc. By storing the conduit members so that they do not protrude outward, the packaging can be made smaller, and by being able to store the conduit members,
Since there is no need to lift the work equipment by grasping the pipe line member or hit the protruding parts, it is possible to protect the fuel tank, etc., and when injecting fuel, the pipe line member does not protrude outward. By doing so, it is possible to more easily inject fuel, and it also has the effect of avoiding the risk of spilled fuel coming into contact with the engine.
