Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The present invention relates to a portable engine working machine with a starting motor for performing welding and other work in the absence of a commercial power source.

(Prior Art) A general structure of a portable engine working machine is one in which an engine and a generator as a working machine which is driven by this engine are mounted inside a frame having wheels for movement mounted at the bottom. It is normal. And as an application, the output of the generator driven by the engine is used as the power source of the lighting,
Or it will be used as a power source for welding. For a small engine, the recoil starter is usually used to start the engine, but when the engine becomes large, a large force is required to pull the recoil starter, and therefore a cell starter is provided as an auxiliary function. If the cell starter is provided, the battery is naturally required.

(Problems to be solved by the invention) When mounting a battery in this way, there are some things to consider. In other words, since this type of work machine is often used for outdoor work, it will continue to be used for a while after starting use, but when the work is completed, it will be in a stored state until the next use, and the need arises. It is likely that the battery will not be charged until it is taken out. Therefore, it is advantageous to use a battery of a relatively large size, and use of a type widely used for automobiles has the advantage that it can be replenished regardless of region.

So when using a battery for this type of work machine,
If you just want to start the engine, you'll be equipped with the most versatile battery that has more capacity than you need. However, using such a large battery makes it difficult to secure a space therefor inside the frame. For this reason, in the past, the battery is mounted outside the frame so as to protrude from the frame. Was normal. This causes the following problems. First, since the battery is outside the frame, it may be damaged by hitting other objects when moving the entire working machine. In addition, since only the battery part projects, a large space is required for storage and installation. There is also a problem that there is no cohesive appearance. The present invention solves these problems by improving the battery mounting position and mounting structure.

(Means for Solving the Problems) As means for solving the above problems, the present invention attaches a moving wheel to a lower portion of a frame formed by bending a pipe material to surround the entire circumference, Inside the frame, an engine and a generator driven to rotate by the engine,
The output shaft of the engine and the rotating shaft of the generator are arranged so as to be directly connected on the same line, and the battery holder is arranged at a position where the outer surface is inside the outer surface of the wheel and the inner surface is opposite the outer surface of the generator. The lower part of the battery holder is detachably attached to the frame by a bracket that holds the frame from both sides, and the upper part is detachably attached to the frame by a weld nut attached to the panel underframe and a bolt screwed to the weld nut. A control panel is attached to the surface of the frame which houses the battery and is located above the battery, and a fuel tank is attached to the upper part inside the frame on the back side of the control panel.

(Operation) With such a configuration, since the battery is mounted in a place that has not been conventionally used as a so-called dead space, no special space is required for mounting the battery. Further, since the outer surface of the battery does not extend outside the moving wheels, there is no risk of the battery being hit by another object and being damaged during the movement. Furthermore, since the battery is externally housed in the frame, the appearance is not impaired. Since the battery holder is detachably attached to the frame, it can be shared with a model that does not use a battery.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 3 and FIG. 4, a portion surrounded by the frame 1 is an engine 4, and a rotation shaft is directly connected to an output shaft of the engine 4 and is driven to rotate by the engine 4 to generate electricity as a working machine. A machine 5, a control panel 6 provided with operation knobs and output terminals for switching output voltage and frequency, a fuel tank 7, a muffler 8 and an air cleaner and a carburetor (not shown) are provided. . The control panel 6 is provided on the surface of the frame 1 above the battery 9 described below, and the fuel tank 7 is provided on the back inside of the control panel 6 inside the frame 1. In addition to this, the battery 9 is mounted in the structure according to the present invention. A recoil starter (not shown) is attached to the engine 4. The engine 4 is designed such that the cylinder 4 is tilted at an appropriate angle with respect to the floor surface so that the overall height becomes low.

The mounting portion of the battery holder 14 will be described with reference to FIGS. 1 and 2. A battery holder 14 is attached to a portion of the frame 1 below the control panel 6 adjacent to the generator 5 via brackets 10 and 11, bolts 12 and nuts 13. The position of the battery holder 14 is such that the outer surface is inside the outer surface of the wheel 3 and the inner surface faces the outer side of the generator 5. Then, the battery 9 is mounted on the battery holder 14. As shown in FIG. 1, the battery holder 14 is generally L-shaped, and the outside is opened so that the battery 9 can be accommodated from that portion. A battery cover provided with a check window 15 at the front of the battery holder 14 so that the liquid level of the battery 9 can be seen.
16 are attached at the sides by bolts 17. The battery cover 16 is inclined upwards, and that portion includes a battery holder 14, a bolt 18, and a weld nut 19.
Covering the panel underframe 20 joined by.

In this portable engine working machine configured as described above, when the battery 9 is mounted at the time of assembly or replacement of the battery, the bolt 16 is loosened, the battery cover 16 is removed from the battery holder 14, and the battery is removed from the front of the battery holder 14. Store 9. After that, the battery cover 16 is attached. After installing the battery cover 16, check window 15
