BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to easily start an engine of a backpack control machine with a starter motor.

[0002]

2. Description of the Related Art Conventionally, in a backpack control machine, an engine is driven by a cell motor, and the cell motor M
It is known that the technology of mounting the battery for driving the. For example, as disclosed in Japanese Utility Model Laid-Open No. 59-130035.

[0003]

However, in the prior art, since the battery is arranged in the part of the battery case integrally formed with the engine, the battery is easily affected by heat generation of the engine, and Since the battery is located further outside the engine,
There was a problem that the battery was caught on the branches and leaves of the tree while working, and the work performance was reduced. According to the present invention, a battery mounting portion is provided in a space on the backrest portion, which has not been conventionally used, so that the space on the backrest portion can be effectively used.

[0004]

The object of the present invention is as described above, and the means for achieving the object will be described below.
In a backpack control machine in which a mounted engine can be started by a cell motor, a mounting portion for a battery for driving the cell motor is provided on a backrest side.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The object and structure of the present invention are as described above. Next, the structure of the embodiment shown in the accompanying drawings will be described. FIG. 1 is a rear view of a backpack control apparatus of the present invention, FIG. 2 is a side view of the same, FIG. 3 is a perspective view of a battery case 4, a battery 5, and a charger 9 and FIG. 4 is a resin frame showing a harness case 2a. 2, FIG. 5 is a side sectional view of the battery case 4, and FIG. 6 is a harness case 2a.
FIG. 7 is an electric circuit diagram showing a portion of FIG.

The overall configuration of the backpack control machine will be described with reference to FIGS. The backpack control machine of this configuration has a base frame made of resin, and the resin frame 2 is integrally formed by blow molding. The upper part of the resin frame 2 is a medicine tank 2b, and the lower part is an engine mounting table 2c.

Further, a recess is formed inside the back pad 3 attached to the front surface of the resin frame 2, and the recess is formed in the harness case 2a. Harness case 2a
Is closed by a harness case lid 19 as shown in FIG. A battery case 4 is disposed on a right side surface of the resin frame 2 when viewed from the back pad 3 side, and the battery case 4 is also covered with a battery case cover 10.

A battery 5 and an engine side coupler 12 are arranged inside the battery case lid 10, and an engine starting switch 20 is arranged below the battery case 4. Further, an accelerator lever 14 is disposed below the engine start switch 20.
A choke knob 15 is disposed below the bottom.

As shown in FIG. 6, an engine stop switch 24 is disposed at a position where the accelerator lever 14 has turned the engine to the stop side. When the accelerator lever 14 is turned to the lowest position, the mounted engine E Are configured to stop. Fuel tank 6 under the mounted engine E
A medicine pump P for pressurizing and discharging the medicine in the medicine tank 2b is arranged at a position below the medicine tank 2b in the portion of the mounted engine E and the output shaft. Reference numeral 30 denotes an opening / closing cock of the medicine tank 2b.

Next, an electric circuit diagram of FIG. 7 having the above-described overall configuration will be described. The cell motor M is arranged inside the mounted engine E, and when the engine start switch 20 is pressed by the operator, the cell motor M starts rotating by the electric power from the battery 5 to start the mounted engine E. However, the recoil starter 16 is also provided when the battery 5 is discharged and the cell motor M does not rotate, or when the cell motor M cannot be driven due to an electrical trouble. Further, when it is desired to stop the mounted engine E, the engine stop switch 24 is turned off by turning the accelerator lever 14 to stop the engine rotation. 25 is a relay.

When the wiring harnesses connecting the relay 25 and the battery 5 with the engine start switch 20 and the engine stop switch 24 are exposed to various parts of the body,
As shown in FIG. 6, a harness case 2a is provided on the surface of the resin frame 2 on the backrest pad 3 side and is stored therein because it may be short-circuited or cut.

Further, the battery 5 is not a battery such as an ordinary automobile or a motorcycle, but is provided with two connecting portions of a battery side coupler 7 and a charging jack 8. Therefore, in the case of charging as shown in FIG. 3, the charging jack 8 is connected to the charger jack 11 of the charger 9, and the charger 9 itself is inserted into the outlet 100 of a household 100-volt power supply. The charger 9 converts the alternating current into a direct current so that the battery 5 can be charged.

After charging is completed, the connecting portion between the charger jack 11 and the charging jack 8 is removed, and the battery side coupler 7 is connected to the engine side coupler 12 on the backpack control machine. Then, the battery-side coupler 7 and the engine-side coupler 12 are fitted to the battery case 4 in a connected state, and the battery case lid 1 is attached.
It is closed by 0.

If the battery 5 has been discharged after a long use, the parts of the engine-side coupler 12 and the battery-side coupler 7 are removed, the battery 5 is taken out of the battery case 4, and the charging jack 8 and the charging jack 8 are connected. Charger jack 11 is connected and left for several hours,
This ends charging. 29 is a carrying band.

FIG. 8 is a front view of a back pad in which a battery case is integrally formed, and FIG. 9 is a side sectional view of the same. As shown in FIGS. 8 and 9, the resin plate surface 3a located on the central back surface of the back pad 3 integrally formed of resin is provided with a recess 3b serving as a battery case on a surface located on the mounted engine E side. Alternatively, the battery 5 may be housed in the recess 3b.

According to this structure, since the central portion of the backrest pad 3 is made thin, and because there is a space between the resin plate surface 3a of the backrest pad 3 and the main body of the control machine, the backrest pad 3 has a small thickness. The battery 5 can be easily taken out by inserting a hand into the space above the resin plate surface 3a from the direction of the back surface of the pad 3 and reaching for the mounted engine E side.

Further, it is not necessary to separately provide a battery case on the side of the fuselage, and only the recess 3b is formed in the conventional back pad 3 itself. Therefore, it is not necessary to provide an extra space and an extra space is required. The battery housing can be constructed at low cost without using materials.

Further, since the concave portion 3b can be provided at the center of the backrest pad 3, the weight of the battery 5 does not depend on the eccentric position of the fuselage, but is substantially at the position of the center of gravity. This eliminates the risk of eccentric loads.

[0019]

Since the present invention is configured as described above, it has the following effects. First, since the battery can be attached to the space on the backrest side in order to use the space on the backrest side, the space on the backrest side, which has not been conventionally used, can be effectively used.

Secondly, since the battery does not project to the outside of the backpack control machine, there is no possibility that the battery gets caught in the branches or leaves during the work, the control work is facilitated, and the work performance is improved.
