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

(Prior Art) Conventionally, in engine working machines such as motor generators, the engine and the working machine are arranged one above the other to reduce the bottom area and make it easier to install on a street or the like in a small space. For example, Tokuko Sho 56-54450
In the publication No. 1, a support frame is vibration-proofly supported on a support stand provided on a base frame forming a case via anti-vibration rubber, an engine is fixed to the upper side of this support frame, and a working machine is fixed to the lower side of the support frame. An engine working machine is proposed in which an engine output shaft and a working machine input shaft are interlocked and connected by a transmission device.

(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.

The purpose of the present invention is to provide an engine working machine that can further reduce the overall height while making use of the small installation space that is a feature of this type of model, improve the packaging density, and have a more compact structure.

(Means for Solving the Problems) Therefore, the present invention provides anti-vibration support for the support frame 21 on the support stands 7, 7 provided in the box-shaped case 1 via anti-vibration rubber 8... Engine 31 above 21
A working machine 41 is fixed to the lower side, and the engine output shaft 34 and the working machine input shaft 42 are connected to the transmission device 7.
1, 72, and 73 are interlocked and connected, and a box-shaped case 1 has a door 1 that can be opened and closed.
1, 12, 13, and 14 are provided, and the engine output shaft 3
The engine 31 is disposed with the cylinder axis extending from the cylinder 3 tilted diagonally upward and sideways, and the cylinder 3
The engine muffler 38 is disposed in the space formed by the support frame 21 and the support frame 21, and a fuel tank 61 is further disposed in the space below the support frame 21.

(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, both upper doors 11 and 13 are formed to be longer than both lower doors 12 and 14 in order to cover the upper half or more of the front and rear surfaces of case body 2.

Furthermore, wire mesh doors 15, 17 are placed inside the upper doors 11, 13.
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 upper door 11,
By having a structure in which the lower doors 12, 14 and the wire mesh doors 15, 17 are held down by the upper doors 11, 13,
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 placed on the bed 21, a generator 41 as a working machine is placed below the bed 21, and a generator 41 is placed on the side of the generator 41. A fuel tank 61 is arranged.

Specifically, as shown in FIG. 1, which shows the arrangement structure of internal devices, vibration-proof rubber 8... A bed 21, which is a support frame, is supported through..., an engine 31 is mounted on the bed 21, and a generator 41 is suspended and supported directly below the engine 31 under the bed 21. The engine 31 is of a recoil starter type, with a recoil starter section 33 disposed on the front side of the case 1, and an output shaft 34 of the engine 31 and a generator 4.
1 input shaft 42 is placed on the back side of case 1, and both shafts 34, 42 are connected to belt 71 and pulleys 72, 73.
Interlockingly connected by a transmission device consisting of. In the figure, 74 is a tension roller.

Further, the engine 31 has a cylinder 32 inclined to one side with respect to the output shaft 34 when viewed from 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. , Exhaust pipe 3 is connected from the cylinder 32 to the back side of the case 1.
7 is disposed, and a muffler 38 is disposed on the back side of the case 1 in the space below the inclined cylinder 32. A vertical piece 22 has a lever 30 formed on the front side of the bed 21 to operate the stop, start, and operation of the engine 31.
facing the horizontally long window 23. 24 in the figure is an oil warning light.

Furthermore, a control box 51 is arranged in the space below 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 below the generator 41 so as to be freely drawn out in a cartridge manner. That is, the fuel tank 61 is disposed within the space on the side of the inclined cylinder 32.

In this way, the generator is housed in the box-shaped case 1, and the brackets 9, 9 on the case side plate 6 are fixed to a utility 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.

Since the engine 31 is placed above and the generator 41 is placed below, the bottom area of the fuselage is small, and when the engine 31 is viewed from the door opening/closing surface, the cylinder 32 is tilted laterally with respect to the output shaft 34. Since the muffler 38 is arranged so that the overall height of the fuselage is low, and the space below the inclined cylinder 32 can be used to arrange the muffler 38, the mounting density can be improved and the fuselage can be configured compactly.

In the embodiment, since the fuel tank 61 is arranged in the space on the side of the generator 41 created by tilting the cylinder 32 laterally, the tank capacity can be increased, and the fuel tank 61 can be kept away from high heat sources such as the engine 31 and the muffler 38. The fuel tank 61 can be placed in isolation.

When the generator is in operation, both lower doors 12 and 14 are closed, and both upper doors 11 and 1 are closed, as shown in FIGS. 6 and 7.
3 is opened and both wire mesh doors 15 and 17 are closed. Since the front and rear upper doors 11 and 13 are 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 lower door.

(Effects of the invention) As described above, according to the engine working machine of the present invention, a door is provided in the box-shaped case housing the engine in the upper part and the working machine in the lower part, and the cylinder is tilted laterally with respect to the output shaft. and place the engine,
The muffler is placed in the space between the cylinder and the support frame, and the fuel tank is placed below the support frame, so while the installation space is small, the overall height is also low, and the mounting density is high, making it very easy to use. Its compact size improves its practicality as an outdoor-installed engine-powered machine.
