Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a brush cutter with a starter motor that can be connected to a power source from the side of a suspension band that can be attached to and detached from the machine and supported by hanging.

[Conventional technology]

Conventionally, in brush cutters that are constructed by interlocking cutting blades on the tip side of an operating rod that extends from an engine equipped with a starter motor that starts when a switch is turned on, the battery for the starter motor is placed on the side of the machine near the engine. It was structured to be equipped.

[Problems that this invention attempts to solve]

As a result, the structure of the machine near the engine side has become larger and heavier, and when working in a suspended state, it becomes difficult to swing due to poor balance, resulting in poor operability and difficulty for workers. The problem is that it can cause fatigue.

[Means for solving problems]

The present invention solves this problem and makes it possible to easily remove the machine from the suspension band without disturbing the wiring. A lower connecting body that can be quickly attached and detached is connected to the upper connecting body on the hanging band side, and a battery is attached to the hanging band and wired to the upper connecting body, and from the lower connecting body to the starter motor side. is constructed by wiring, and both the upper and lower connectors are provided with terminals that can be connected to and separated from the upper and lower connectors when they are connected to each other.

[Effect]

Therefore, by attaching the battery to a suspension band that is placed on the worker's shoulder, the battery can be carried without increasing the size of the machine and without putting any strain on the machine. can be connected to the cell motor side, and if you want to remove the unit with the suspension band on your shoulder as usual,
The terminals are separated from both the connectors and can be removed without any problem with the wiring.

〔Example〕

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a perspective view of a brush cutter, in which a long operating rod 3 with a transmission shaft 14 inside extends from a clutch case 13 on the engine 2 side.
The cutting blade 4 is placed below the gear case 15 connected to the tip of the blade 4.
The crankshaft 16 of the engine 2 has a ring gear 1 on its outer periphery.
7 and a cooling fan 19 having a centrifugal clutch shoe 18 inside thereof is connected to the clutch drum 20 connected to the transmission shaft 14 so that the centrifugal clutch shoe 18 is inscribed therein.

Further, on the lower side of the clutch case 13, a starter motor M is installed in a holder 21 having a finger seat on the outside.
The wiring 9 is installed so that the pinion 24 of the starting motor M connected to the torque spring 23 can mesh with the ring gear 17, and the wiring 9 is arranged along the operating rod 3. The switch 1 connected to the starting motor M and interposed on one side of the wiring 9 is connected to the pinion 2.
4 meshes with the ring gear 17.
While rotating the movable contact 1 to the fixed contact 1a.
b, 1b are installed and configured so that they can be connected and turned on.

A lower connecting body 7 is attached to the upper part of the support metal 25 that is fitted and fixed to a portion of the operating rod 3 near the engine 2.
At the same time, an upper connecting body 6 is connected to the lower part of the suspension band 5 that can be hung on the worker's shoulder, and a connecting piece 6a having a hole 26 is hung from the upper connecting body 6. The hole 26 is provided inside the lower connecting body 7 into which the connecting piece 6a can be inserted from above.
An engagement spring plate 7a that can be engaged with the upper connecting body is inserted, and the upper coupling body 6 and lower connector 7
and are installed and configured so that they can be quickly attached and detached from each other.

Further, a case 8a is attached to the middle of the suspension band 5 through which the battery 8 can be inserted and removed, and both pin jack-shaped terminals 10 protruding from the lower surface of the upper connecting body 6 and the battery 8 are attached to the suspension band 5. Pin jack-shaped terminals 11 are installed on the upper surface side of the lower connecting body 7 to which both terminals 10 can be removably fitted. 3 to form the circuit shown in FIG. 6.

Therefore, when the hanging band 5 is put on the worker's shoulder and the upper connecting body 6 is pushed into the lower connecting body 7 to connect them as shown in FIGS. 7 and 8, both terminals 10 and both terminals 11 are connected. By connecting it, you can carry the brush cutter by hanging it.

To start the engine 2, put your finger on the finger seat 21 and push the starter motor M as shown by the imaginary line in FIG. This turns on, and the engine 2 can be started by driving the starting motor M, so that the mowing operation can be carried out by suspending and supporting the suspension band 5.

To remove the brush cutter at the end of work or to immediately remove the brush cutter from the worker in case of danger, push down the release piece 27 on the side of the lower connecting body 7, and the engagement spring plate 7a will release the connecting piece 6a. This means that the lower connecting body 7 can be immediately separated from the upper connecting body 7 to remove the brush cutter, and the connection with the battery 8 can be disconnected and removed without pulling the wires one by one. It will be possible.

[Effect of idea]

In this way, in the present invention, the battery 8 is attached to the hanging band 5 that is worn on the worker's shoulder, so the brush cutter side becomes smaller and lighter, improving operability, and does not interfere with the grass cutting work. In this way, the battery 8 can be carried around, and the power can be automatically connected by connecting the upper and lower connectors 6 and 7, so that when the brush cutter is removed with the hanging band 5 on the shoulder as usual, , both the upper and lower connectors 6, 7 and the terminals 10, 11 are automatically and properly separated, without having to pull the wires one by one.
Moreover, it can be removed in a safe state, and has the advantage of being of a simple structure and suitable for implementation.
