JPH0632857Y2 - Battery mounting structure for backpack type working machine - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a battery mounting structure for a backpack-type working machine in which a battery for a starter motor mounted on a machine body is mounted on the front side of the machine body.

[Prior Art] Conventionally, in a backpack-type working machine that is equipped with an engine with a starter motor and can be carried by a backpack band, for example, as seen in Japanese Utility Model Laid-Open No. 59-131270, the battery is a liquid tank. It was structured so that it would be equipped below.

[Problems to be solved by the invention] Therefore, the liquid chemicals and fuel are easily attached to the battery and the waterproof property is poor, and when the user carries the battery, the battery is located at the lower rear side of the aircraft, so that the weight of the battery does not work. It presents a problem that the person feels unbalanced due to imbalance.

[Means for Solving the Problems] The present invention solves such a problem and enables the battery to be attached to the operator's back side in a close manner, and therefore, the front surface of the machine body. The back support (4) or the waist support (5) provided on the side is provided so as to be openable at one end in the lateral direction, and the battery (6) for the starter motor (1) is attached to the back support (4) or the waist. The pad (5) is stored horizontally with the cushion material (21) intervening from the side, and the battery (6) is stored in the back support (4) or the waist support (5) so that it can be taken in and out freely. The cushion material (21) is provided between the battery (6) and the back of the worker.
It is configured such that a part of the can be buffered.

[Operation] Therefore, when the battery is placed inside the backrest or the waistrest so that it can be taken out during charging, it can be equipped with a waterproof cover to prevent chemicals and fuel from adhering to it. In addition, since the battery in the lateral direction comes close to the operator's back with the cushioning material interposed, it is comfortable to carry on the back and can be carried on the back in good balance.

[Embodiment] Next, an embodiment shown in FIGS. 1 to 4 will be described.

Fig. 1 shows a side view of a backpack-type working machine which is a power sprayer. A drug tank (8) is integrated on top of the machine frame (7) on which the engine (2), pump (P), etc. are mounted. The fuel tank (9) is joined to the rear surface side of the medicine tank (8),
On one side, a plurality of locking pieces (11) capable of hooking the spray pipe (10) communicating with the pump (P) are projected, and a latch (12) provided on the front side of the drug tank (8). , Both ends of both shoulder straps (3) are respectively connected to both locking bodies (13) provided on the lower portions of both sides of the machine frame (7), and are also connected to side portions of the engine (2). The recoil starter part (14) and the starter motor (1) are power-coupled via the gear transmission case (15), and the recoil starter part (14) can be started by a starting rope linked to the knob (17). As shown in FIG. 4, a circuit for connecting the engine (2), the starter motor (1), the switch (18), the relay (19), and the battery (6) is formed.
The structure is the same as the conventional structure.

A cushion material (2) is provided above and below the front surface of the back support plate (20) stretched from the lower front surface of the medicine tank (8) to the front surface of the machine frame (7).
Wear the horizontal backrest (4) filled with 1) and the waist rest (5), respectively, but cover piece (5
a) is opened and closed so that the inside can be opened, and is fixed by a hook (22), and the battery (23) is arranged sideways with a cord (24) having a connector (23) at the tip that can be connected to the starter motor (1) side. 6) is inserted into and removed from the waist rest (5) so that part of the cushion material (21) is placed between the battery (6) and the operator's back side as shown in FIG. It is configured to be interposed.

When the battery (6) is inserted inside the backrest (4) or when the backrest (4) and the waist rest (5) are connected to form one backrest, A battery (6) will be installed inside to configure.

Therefore, open the cover piece (5a), insert the battery (6) inside the waist rest (5), and use the hook (22) to insert the cover piece (5a).
It can be installed by closing the cord (24) and connecting the cord (24) to the starter motor (1) side via the switch (18) and the relay (19) .When charging, the cover piece (5a) can be opened and taken out. become.

If it is installed in this way, it will be possible to install it by covering it with a waist support (5) with good waterproofness so that chemicals, fuel, etc. do not adhere, and when the aircraft is carried on its side, ) Will approach the operator's back side with the cushioning material (21) interposed, so that the battery (6) can be carried in good balance and comfortably on the back without damaging the battery (6).

FIG. 5 shows another example, which is a backpack type brush cutter, and an engine (2) having a recoil starter portion (14) which is started by a starter motor (1) and a knob (17) on a machine casing (7). Is rotatably mounted, and a cutting blade is transmission-coupled to the tip side of a flexible transmission shaft (25) extending from the engine (2),
A back support (4) was attached to the front of the front of the machine frame (7) in which both shoulder straps (3) were connected, and hooks (22) were attached to the sides of the back support (4). Open the cover piece (4a)
The battery (6) is configured to be inserted and removed freely in the inside of (4) with a cushioning material interposed as in the above-described embodiment.

[Advantage of the Invention] As described above, in the present invention, the battery (6) is installed sideways on the backrest (4) or the waistrest (5) so that it can be easily taken out during charging, so that the chemical solution or the fuel can be used. It will be possible to equip it with a waterproof cover so that it will not adhere, and the battery will be warmed by the worker's body temperature in cold weather, so the battery performance will not deteriorate and the horizontal battery (6) Will approach with the cushioning material (21) interposed on the operator's back side.
Without damaging the battery (6), it will be well-balanced and comfortable to carry,
The battery (6) has a feature that it can be made into a compact structure so that it does not occupy space and can be preferably implemented.
