Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a walk-behind engine working machine such as a tiller.

(Prior art) When equipping a walk-behind engine working machine such as a power tiller with a cell starter, the battery, which is relatively heavy, should be placed near the center of gravity of the machine and on the hand side where maintenance is easy. will be held. For example, as disclosed in Japanese Utility Model Application Publication No. 59-38183, it is common to arrange a battery behind the engine mounted on the engine bed.

(Problem to be solved by the invention) By the way, the cell starter should preferably be placed in front of the engine to facilitate maintenance, but the wiring connecting the cell starter and the battery placed before and after the engine is difficult. The problem is the route. That is, there are various types of movable equipment such as a throttle, clutch, belt, etc. arranged above and on the sides of the engine, and there is a possibility that the wiring at the bottom of the engine bed may be damaged by splashing mud or stones.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a walking-type engine working machine in which the engine bed is modified so that wiring can be routed using the bed, and the risk of damage to the wiring is eliminated.

(Means for Solving the Problems) In order to achieve the above object, the present invention forms the engine bed 20 in the shape of a hollow box, and uses wiring to connect the cell starter 14 and battery 13 disposed at the front and rear of the engine 2, respectively. 15 to engine bed 2
It is characterized in that the wire runs within 0.

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

FIG. 1 is a perspective view of a walking engine working machine 1.
FIG. 2 is an enlarged front view of the engine bed 20, and FIGS. 3 and 4 are a side view and a plan view of the engine bed 20.

The engine 2 is mounted on the engine bed 20, a transmission case (not shown) is connected to the rear of the bed 20, a transmission case 5 is provided on one side of the engine 2, and the transmission case 5 is mounted on the transmission case. A handle post 6 is connected thereto, a handle pipe 7 projects from the post 6, and drive wheels 8 are disposed on both sides of the lower part of the transmission case. Further, a fuel tank 9 is installed above the engine 2, a headlight 11 is installed in front of the fuel tank 9, and a muffler 12 is installed above the transmission case 5.

A cell starter driving battery 13 is attached to the side wall of the handle post 6, and a cell starter 14 is attached to the front wall of the crankcase 3 of the engine 2. An oil drain cap 4 is disposed at the lower part of the front wall of the crankcase 3 below the cell starter 14.

The engine bed 20 has a wide engine mounting plate 31 on a hollow box part 21 that is long in the front and rear direction.
It is made by fixing. That is, the front and rear of the hollow box part 21 are open, the bottom wall 22 of the box part 21 is formed flat, the upper edge 23 rises up as if the front part 24 is tilted forward, the rear part 25 is raised greatly as if it is tilted backward, and the upper edge 23 is formed in the middle. The portion 26 is formed to be higher toward the rear with respect to the bottom wall 22, and the middle portion 32 is flat on the upper edge 21 of the box portion 21.
The engine bed 20 is constructed by integrally joining a mounting plate 31 with a front part 33 bent high forward and upward and a rear part 34 bent high rearward and upward.

The mounting plate 31 is sufficiently wider than the box part 21, and two elongated holes 36 for engine mounting are formed in the left and right parts 35, 35, and the left and right side edges 37, 37 are bent downward. to ensure rigidity.

The front upper part of the engine bed 20 is provided with a U-shaped hitch 55 which is integrally joined with bolts 56 and welding or brazing, and the rear part serves as an attachment part to the transmission case.

In the above, the intermediate portion 32 of the mounting plate 31
Wiring holes 41 and 42 are respectively opened in the central part of the front part 33 and the central part of the rear part 34 which are located at a higher position,
Each hole 41, 42 faces above the box part 21.

A cross pipe 28 is laterally passed through and fixed to the front middle part of both side walls 27, 27 of the box part 21, and a plate is located in front of the pipe 28 and faces the oil drain cap 4 close to the top. Oil drain holes 44 are opened at 31 locations,
The hole 44 faces above the box part 21. This drain hole 44 is formed within the recess 43 .

Furthermore, the box portion 21 below this drain hole 44
A drain guide 45 is fixed to one side wall 27 inside. The drain guide 45 forms a space with the other side wall 27, the bottom piece 46 is slightly inclined downward, and the bottom piece 46 is provided with upstanding pieces 47 and 48 bent upward at the front and rear thereof.

By the way, the stand 16 is pivotally supported by the cross pipe 28, and the stand 16 is biased toward the falling side by the return spring 17.

Hollow box part 2 of the engine bed 20 above
1, pass the wiring 15 through the front and rear wiring holes 41, 4.
Wiring 15 from bushings 51 and 52 fitted to 2
The front and rear of the battery are raised upward, and each is connected to the cell starter 14 and battery 13. Here, the wiring 15 passes above the cross pipe 28 and below the base of the drain guide 45, and is maintained in a stretched state by the bushings 51 and 52 by pulling the front and rear ends.

Since the wiring 15 is routed inside the hollow part of the engine bed 20 in this manner, the wiring 15 can be protected from the outside.

Next, the engine oil draining process will be explained.

First, the stand 16 is raised and placed on the ground. As a result, the front part of the fuselage is lowered and the rear part is raised, so that the bottom wall 22 of the box part 21 of the engine bed 20 is lowered forward.

When the cap 4 is removed, the oil flows into the box part 21 from the drain hole 44, falls onto the bottom wall 22 from one side at the drain guide 45, and is discharged from the front opening according to the slope. .

In this way, when draining oil, drain guide 4
5 prevents oil from falling onto the wiring 15, and especially since the guide 45 is provided with a front upright piece 47, the guide 4 can be prevented from falling onto the wiring 15.
5. Oil falling onto the wiring 15 from the front can be effectively prevented. Further, since the wiring 15 is restricted from downward by the cross pipe 28, the wiring 15 can be separated upward from the bottom wall 22 and run.

Furthermore, since the hole 41 for taking out the front part of the wiring 15 is provided at a high position, the wiring 15 can be separated upward from the oil flowing on the bottom wall 22.

According to the embodiment, the wiring 15 can be protected even during oil drain.

(Effects of the invention) As described above, according to the walking-type engine working machine of the present invention, the wiring connecting the cell starter and battery placed at the front and rear of the engine is routed through the engine bed formed in the shape of a hollow box. Since the wires are wired, protection of the wiring from the outside can be achieved.

Furthermore, if configured as in the embodiment, protection of the wiring during oil draining can also be achieved.
