Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to working machines such as power pest control machines, power spreaders, and power brush cutters. This is related to.

(Prior Art) As a conventional starting device for a backpack-type working machine, there is one shown in FIGS. 4 and 5, for example (see Japanese Utility Model Application Publication No. 118259/1983). In this starting device, when carrying the working machine 1 on one's back, a grip holder 3 is attached to the side of the backpack frame 2, and the starter grip 4 is held in the holder 3. It is designed to be operated by pulling it out to the front.

(Problems to be Solved by the Invention) However, in the case of the above-mentioned configuration, the starter grip must be pulled out from the left rear of the body to the front, and must be operated in an extremely uncomfortable posture. Also, since you have to pull out the starter grip by pushing out your arm, it is difficult to put pressure on your arm. Additionally, this part usually has a throttle device, which has the disadvantage of not being very practical.

In addition to the above, there is also one in which the starter grip is placed on the opposite side of the backpack frame, as shown in Japanese Utility Model Application No. 56-154517. in this case,
It is impossible for a worker to start the engine while carrying the work machine on his or her back, and if the engine is temporarily stopped during work, it is necessary to take the work machine down in order to restart it, which is very inconvenient.

In addition, there is one in which a starter rope is guided by a flexible guide tube as shown in Japanese Utility Model Application Publication No. 59-19975. However, in this case, since the guide tube is not positioned, it gets in the way during work, makes it difficult for the rope to move at the time of starting, and makes it difficult to perform a smooth pulling operation. Additionally, when the work equipment is lowered, the starter grip touches the ground and gets dirty.

(Purpose of the invention) The present invention was made in order to eliminate the various drawbacks mentioned above. It is an object of the present invention to provide a starting device that can easily perform a starter grip pulling operation.

(Means for solving the problems) a. This is a backpack-type work machine in which at least the engine part is carried on the back using a backpack frame and a backpack band.

b. Attach a rope guide along the backpack band to the vicinity of the shoulder contact area of the backpack band, and use this rope guide to hold the recoil starter rope.

c. Tie one end of the rope to the recoil starter reel and the other end to the rope pulling starter grip.

(Function) The present invention is constructed as described above, and when a worker carries a working machine such as a power spreader or a power brush cutter on his or her back, the starter grip of the recoil starter is positioned exactly on the shoulder of the worker. It will be done.

Therefore, when starting the engine, the starter grip is pulled diagonally downward with the hand on the opposite side of the starter grip. Also, place the work equipment on the ground,
You may start the engine by pulling the starter grip toward you.

In this way, when you pull the starter grip,
Since the rope guide of the recoil starter draws a large arc along the worker's shoulders, the rope is pulled out smoothly in a gentle curve, rotating the recoil starter and starting the engine.

After starting the engine, the spring in the recoil starter unwinds the rope and the starter grip returns to its original position on the operator's shoulder.

(Example) A case where an example according to the present invention is applied to a power spreader will be explained with reference to the drawings. Figure 1 is a side view showing a worker carrying a power spreader on his back.
10 is a worker, and 11 is a power spreader which is one of the working machines, and is composed of an engine 12, a chemical tank 13, a fuel tank 14, and the like. Reference numeral 15 denotes a backpack frame, which is approximately L-shaped when viewed from the side, and a back support 16 made of an elastic material is attached to the back contact portion of the worker 10.
is attached to hold the driving force spreader 11. 17 is a starter grip, and the starter grip 17 has a reel 24 of the recoil starter 18.
(See FIG. 3) is tied to a rope 19 wound around the rope 19 (see FIG. 3). 20 is a rope guide, and the above rope 1
9 is pierced. Reference numeral 21 denotes a shoulder strap, and the rope guide 20 is attached to the shoulder strap near the shoulder contact portion 22 of the worker 10.
This rope guide 20 is shown in FIG.
Hold the backpack frame 1 with the holding material 23 as shown in the line cross-sectional view).
5 and the backpack band 21 at multiple locations. The holding material 23 is fixed to the backpack band 21 by sewing or the like.

Next, the relationship between the recoil starter 18 and the engine 12 will be briefly explained with reference to FIG. The recoil starter 18 has a reel 24 around which a rope 19 is wound.
and a cover 25. On the other hand, a fan 27 and a transmission shaft 28 are fixed to a crankshaft 26 of the engine 12 with bolts 29. By pulling the rope 19 of the recoil starter 18, a claw (not shown) built into the recoil starter pops out, engages with the transmission shaft 28, rotates the crankshaft 26, and starts the engine 12. .

(Effects of the invention) As described above, according to the invention, a rope guide is attached along the backpack band, and the starter grip of the backpack-type work machine is located near the shoulder contact area, so that the worker's hand can It is now easier to reach the starter grip, and the starter grip can now be pulled diagonally downward, making it easier to start the machine while carrying it on your back.

In addition, during work such as chemical spraying or mowing, when it is necessary to remove weeds or obstacles such as stones, even if the engine is stopped, it can be restarted immediately, significantly improving work efficiency. Now I can do it.
