Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to an engine working machine.

(Prior Art) The present applicant has proposed in Japanese Patent Application No. 128764/1987 that an engine is placed in the lower part of a case, a generator is placed in the upper part, and the engine output shaft and the generator input shaft are connected via a transmission device. We proposed a motor generator that is connected to each other. According to this, since the engine and generator are arranged one above the other, the bottom area of the aircraft body is reduced, and the installation space can be reduced, making it suitable for installation on the street.

(Problems to be solved by the invention) By the way, in such an engine working machine,
Furthermore, the overall height of the aircraft body is required to be low, and the packaging density is high and it is required to be more compact.

An object of the present invention is to provide an engine working machine that requires less installation space, has a lower overall height, and has improved packaging density, so that it can be configured more compactly.

(Means for solving the problem) Therefore, the present invention has two side plates 5 of the box-shaped case 1,
The engine 31 is housed below the support frame 21, which is anti-vibration supported by a support stand provided at 6, via anti-vibration rubber, and the work implement 41 is housed above the engine output shaft 34 and the work implement input shaft 42. Transmission device 71, 72, 73
In an engine working machine connected with is arranged so as to extend obliquely upward, and a muffler 38 is disposed within a space formed by the cylinder 32 and the inner bottom surface of the case.

(Embodiment) A preferred embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

2 to 7 are perspective views of an engine working machine implementing the present invention, in which a box-shaped case 1 forms a vertically long rectangular parallelepiped, a lower plate part 3, an upper plate part 4, left and right side plate parts 5,
A case body 2 consisting of 6 has an upper door 11 and a lower door 12 which are hinged at one side edge and can be opened and closed on the front side, and an upper door 13 and a lower door 14 which can be opened and closed on the back side. Here, the lower doors 12 and 14 are formed to be longer than the upper doors 11 and 13 so as to cover the lower half or more of the front and rear surfaces of the case body 2.

Furthermore, wire mesh doors 15, 17 are placed inside the lower doors 12, 14.
Similarly, the six doors can be opened and closed freely, and the above six doors can be locked and unlocked using a locking device. In particular, in the structure of the embodiment, as is clear from the drawings, the lower door 12,
By having a structure in which the upper doors 11, 13 and the wire mesh doors 15, 17 are held down by the lower doors 12, 14,
All six doors are locked with a chisel lock.

The inside of the case body 2 is divided into upper and lower parts by a bed 21, an internal combustion engine 31 is arranged below the bed 21, a generator 41 which is a working machine is placed on the bed 21, and a generator 41 is placed on the side of the generator 41. A fuel tank 61 is arranged.

Specifically, the bed 21 is supported via a mount rubber 91 serving as vibration-proof rubber at approximately the center in the vertical direction of the side plates 5 and 6 of the case body 2, and the bed 21 is
An engine 31 is suspended and supported, and a generator 41 is mounted directly above the engine 31 on the bed 21. The engine 31 is of a recoil starter type, with a recoil starter section 33 arranged on the front side of the case 1, an output shaft 34 of the engine 31 and an input shaft 42 of the generator 41 arranged on the back side of the case 1, and both shafts 34, 42 are interlocked and connected by a transmission device consisting of a belt 71 and pulleys 72 and 73. In the figure, 74 is a tension roller.

In addition, the engine 31 has a cylinder 32 inclined to one side with respect to the door opening/closing surface, and a carburetor (not shown) and an air cleaner 36 are arranged on the front side of the case 1 with respect to the cylinder 32. An exhaust pipe 37 is arranged on the back side, and a muffler 3 is placed on the back side of the case 1 in the space below the inclined cylinder 32.
Place 8. A lever 30 for controlling stop, start, and operation of the engine 31 is made to face a horizontally elongated window 23 of a vertical piece 22 formed on the front side of the bed 21. 24 in the figure is an oil warning light.

Furthermore, a control box 51 is arranged in the space above the generator 41. control box 5
The input cord 49 from the generator 41 is connected to the back side of the 1, and the dedicated output terminal 5 provided on the back plate 52.
A dedicated output cord 54 is connected to the case 3, and the dedicated output cord 54 is led out from a drawer section provided on the case lower plate section 3. Also control box 51
A general-purpose output terminal, that is, an outlet 56 is provided on the front plate 55 of the main body, and a display section 58 such as a frequency indicator and a time meter is also provided.

A fuel tank 61 is housed in a side space of the generator 41 and the control box 51 above it so as to be freely drawn out in a cartridge manner.

The arrangement structure of the above internal equipment is shown in Fig. 1.
In the figure, 81 is a muffler separator surrounding the muffler 38.

In this way, the motor generator is housed in the box-shaped case 1, and the brackets 7, 7 on the case side plate 6 are fixed to a telephone pole with a metal band, or installed on a special post, so that it can be installed outdoors at a relatively high height. It is placed at a location and used as a power generator for signal lights in emergencies.

Because the engine 31 is placed at the bottom and the generator 41 is placed at the top, the bottom area of the aircraft is small.Moreover, the engine 31 is placed with the cylinder 32 slanted laterally with respect to the door opening/closing surface, so the aircraft The overall height of the airframe is reduced, and the space below the inclined cylinder 32 can be used to arrange the muffler 38, so the mounting density can be improved and the airframe can be configured compactly.

When the generator is in operation, both upper doors 11 and 13 are closed, and both lower doors 12 and 1 are closed, as shown in FIGS. 6 and 7.
4 is opened and both wire mesh doors 15 and 17 are closed. Since the front and rear lower doors 12 and 14 are thus opened and the wire mesh doors 15 and 17 are closed during operation, the engine 31 can be cooled and the internal equipment can be protected from tampering.

By the way, in the example, a motor generator was used, but
The present invention is also effective for other engine working machines. It is also possible to further divide the upper door.

(Effects of the invention) As described above, according to the engine working machine of the present invention, the cylinder is placed laterally with respect to the opening/closing surfaces of the doors provided on both the front and rear sides of the box-shaped case that houses the engine in the lower part and the working machine in the upper part. Place the engine at an angle,
In addition, since the muffler is assembled in the space below, the installation space is small, the overall height is low, and the mounting density is high, making it very compact, improving the practicality of an outdoor-installed engine-powered machine.
