Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an engine starting device for a backpack-type power spreader, which allows the engine to be started while carrying the machine on the back.

[Prior Art] In conventional backpack-type power spreaders of this type, in order to start the engine, the machine must be lowered to the ground and started by grasping the starter knob on the rear side of the machine, or another person must perform the starting operation. A typical structure is such that the starting operation is performed at the rear of the aircraft.

[Problems to be solved by the invention] Therefore, when working with the aircraft on one's back, if the engine stalls, starting the engine becomes troublesome.

[Means for solving the problem] The present invention solves the problem and makes it possible to start the engine easily while carrying the bag on one's back, and also allows the handle body to be stored well. Therefore, a guide path for the starting rope extends from the engine's recoil starter toward the side of the backpack, and the end of the starting rope extending from the tip of the guide path is shaped like a T-shape at the tip. The handle body is connected to a handle body having a knob, and a recessed portion is formed in the base of the handle body so that the handle body can be engaged with the mouthpiece by changing its posture to a hanging state in a perpendicular direction.

[Function] Therefore, if the engine stalls during work, you can easily grasp the handle while carrying the aircraft on your back and start the engine by operating the handle. During work, the handle body can be stored in a hanging state so that it is easy to reach when starting up, and so that it does not get in the way or cause rattling.

[Example] Next, the embodiment shown in the drawings will be described.

FIG. 2 shows a perspective view of a backpack-type power sprayer, in which a drug tank 9 is installed at the rear upper part of the back support 3 having a shoulder strap, and below the drug tank 9,
It is equipped with an engine 1 having a recoil starter 2 at the rear and a blower 10, and has a dispersion pipe connected to an elbow 11 extending laterally from the blower 10, similarly to the conventional structure.

A guide path 5 formed with a cover is provided extending from the side of the recoil starter 2 to the upper outer side of the elbow 11, and a bent part of the guide path 5 is provided with a guide path 5 from the recoil starter 2. A roller 1 that engages and guides the extending starting rope 4
2 and 13 respectively, and a terminal end of the guide path 5 that opens toward the lateral side of the backrest 3,
A cap 6 whose outwardly protruding portion has a truncated conical shape
is fixedly constructed so that the starting rope 4 can be inserted therethrough.

Reference numeral 7 designates a rod-shaped handle body, with a T-shaped knob 7a integrally formed at the tip thereof, and a base 7 of the handle body 7.
b, a handle body 7 is attached to the protruding tip of the base 6;
A recess 8 is formed so that the starting rope 4 can be engaged by changing its posture to a hanging state in the orthogonal direction, and the end of the starting rope 4 extending from the base 6 is passed through the recess 8 and into the inside of the handle body 7. Constructed by extending and connecting.

Note that the base portion 7b of the handle body 7 is also formed so that it can be gripped.

Therefore, when carrying out work with the machine on the back, as shown in Figures 5 to 7, the base 6
When the recess 8 is engaged with the handle body 7, the handle body 7 is in a drooping state, and the handle body 7 is held in a hanging state to prevent rattling caused by the swinging of the aircraft body and to prevent the handle body 7 from getting in the way.
can be kept in storage.

In addition, when starting the engine for the first time or when an engine stall occurs, the base 7b of the handle body 7 or the knob 7a, which is in a state where it is easy for the operator carrying the machine on his back to reach with his hand, is provided. As shown in FIGS. 1 to 4, the handle body 7 is brought into a horizontal position so that the recess 8 remains engaged with the base 6, and then the knob 7a is placed with a finger and the arrow mark is pressed. If the engine 1 is pulled safely in the direction, the engine 1 can be started, and after the engine 1 is started, the handle body 7 that has moved back can be folded and stored in a hanging state.

[Effect of the invention] As described above, the present invention has the advantage that the tip side cap 6 of the guide path 5
The handle body 7 is attached to the base 6 so that the recess 8 engages with the handle body 7.
Since the posture can be changed to a hanging state at right angles to the handle body 7, when working while carrying it on your back, keep the handle body 7 in a hanging position and store it well to prevent it from rattling or getting in the way. This means that when starting the engine, you can keep the aircraft on your back and lift it up while placing your hand on the handle body 7, which is in a hanging state so that you can easily put your hand on it, and you can start the engine reliably and easily. It has a simple structure with good operability and can be suitably implemented.
