Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a battery cover mounting structure for a mobile work machine.

(B) Conventional technology Conventionally, a battery cover for a mobile work machine has a battery storage space formed on the top surface of a handle support base that supports the base end of a control handle, and a battery is disposed in the space. It is mounted on the handle support base so as to cover it.

Moreover, the battery cover is fixed to the support by fitting its tip into the groove of the guide plate for supporting the gear shift lever provided at the rear end of the handle support, and by screwing a fixing pin into the base end of the cover. has been done.

When replacing or inspecting the battery, etc., open the battery by removing the fixing pin at the base end of the battery cover, sliding the battery cover forward, and removing the tip of the cover from the guide plate. condition.

(c) Problems that the invention aims to solve: When replacing or inspecting the battery, the replacement work cannot be performed unless it is completely removed, and the work of installing and removing the battery cover requires a lot of effort.
It has the disadvantage of being complicated.

(d) Means for solving the problem The present invention provides a mobile work machine in which a battery is placed on a handle support stand that supports the base end of a control handle, and a battery cover that covers the battery is attached to the support stand. , an inverted U-shaped support rod is provided at the front end of the support stand, and a support rod in the shape of an inverted U is installed in the support rod, and a recessed groove in the front and rear longitudinal direction provided in the ceiling of the battery cover is attached to the support rod, and the support rod is supported in the recessed groove. A substantially convex arc-shaped elastic body is attached to hold the rod, and the battery cover is configured to be able to slide back and forth and move up and down, and furthermore,
It is an object of the present invention to provide a mounting structure for a battery cover in a mobile working machine configured to fix the tip end of the battery cover to a handle support base.

(e) Functions and Effects In the present invention, the tip of the battery cover is fitted into the fitting groove of the speed change lever-shaped guide plate, and the elastic body holds the support frame in the groove of the ceiling of the cover. By doing so, the battery cover is closed and fixed to the handle support base.

Furthermore, since the battery cover has a concave groove in which the support rod is attached in the front and rear longitudinal direction, and the support rod is held between convex arc-shaped elastic bodies, the battery cover can be fixed securely and easily. It slides back and forth.

Then, the battery cover is opened by removing the distal end of the battery cover from the handle support base and rotating it upward around the support rod held by the elastic body.

Therefore, in the present invention, since the battery cover can be opened and closed with a one-touch operation, replacement or inspection of the battery can be easily and quickly performed with a simple operation, which is effective.

(F) Example The example of the present invention will be explained in detail based on the drawings.
In Fig. 1, A indicates a walk-behind cultivator as a mobile working machine, and the cultivator A has a rotary section 2 connected to the rear of a traveling machine body 1, and while traveling with the traveling machine body 1, it rotates around the rotary tiller. Plowing work is done in part 2.

This traveling body 1 has a prime mover 4 mounted on a body frame 3, and the prime mover 4 and the upper part of a transmission case 5 are interlocked and connected via an interlocking case 6, and wheels 7 are mounted on the lower part of the transmission case 5. It is installed so that it can move freely.

A handle support base 8 protrudes rearward from the upper portion of the transmission case 5, and a control handle 9 is connected to and supported on the support base 8 facing rearward.

In addition, 10 is a rotary frame of the rotary part 2, 11 is a tail wheel attached to the rear end of the same frame 10 via a tail wheel support rod, 12 is a rotary case hanging down from the same frame 10, and 13 is at the lower end of the same rotary case 12. The tilling claws 13 are connected to each other, and the tilling claws 13 are operated by a transmission shaft that transmits power from the transmission case 5 to the rotary case 12.

Furthermore, as shown in FIG. 1, a battery mounting section S is formed in the center of the handle support base 8 of the traveling body 1, and a battery 15 is mounted on the mounting section S. The battery cover 16 is attached freely, and the battery cover 1
The detailed structure of No. 6 is as follows.

That is, a guide plate 17 for supporting the gear shift lever is provided at the rear end of the handle support base 8, and the guide plate 17
The tip 16a of the battery cover 16 is fitted into the fitting groove 17a.

Furthermore, an inverted U is provided at the upper end of the transmission case 5.
A letter-shaped support rod 18 is provided to protrude upward, and the support rod 18
through the proximal ceiling portion 1 of the battery cover 16.
9 is installed.

Moreover, the battery cover 16 is attached to the support rod 18.
It is formed so that it can slide in the front and rear directions around the center and can freely move up and down.

That is, a concave groove portion 20 in the front and rear longitudinal direction is formed in the base end ceiling portion 19 of the battery cover 16,
The groove portion 20 is attached to the support rod 18.

Note that 20-1 is a protrusion that forms a groove 20 in the base end ceiling part 19 of the battery cover 16, and 20a and 20b are front and rear engagement parts provided before and after the groove 20. Each engaging portion 20a,
A support rod 18 is connected to 20b via an elastic body 21, which will be described later.
engage.

Further, a substantially convex arc-shaped elastic body 21 that can hold the support rod 18 is attached to the concave groove portion 20. The elastic body 21 is made of a flat spring 21a, and the base end of the flat spring 21a is It is connected to the front end of the groove 20 via a tapping pin 22, and the support rod 18 in the groove 20 is clamped by the convex arc 21b of the flat spring 21a so as to urge it either forward or backward.

With this structure, as shown in FIG. 2, the battery cover 16 has its distal end 16a fitted into the fitting groove 17a of the guide plate 17, and the proximal end of the battery cover 16 fitted into the support rod 18 with an elastic body. It is clamped and fixed via 21.

Further, the support rod 18 is connected to the battery cover 16.
Since it is attached to the base end of the cover 16 through the groove 20 in the front-rear longitudinal direction, it slides in the front-rear direction, and the tip 16a of the cover 16 is inserted into the fitting groove 1 of the guide plate 17.
7a is removed.

Then, the battery cover 16 is held between the supporting rod 1 by the tip of the elastic body 21 in the concave groove 20.
The battery 15 can be opened by rotating around 8.

In addition, at this time, the elastic body 21 allows the support rod 18 to push down the elastic body 21 and slide the battery cover 16 back and forth due to the convex arc portion 21b. The battery cover 16 can be opened and closed using the battery cover 18 as a rotational fulcrum, and in this state, the battery cover 16 can be held by the elastic body 21.

In addition, since the elastic body 21 has a distal end spaced apart from the rear engaging portion 20b of the concave groove portion 20 with a distance L, the battery cover 16 can be attached and detached from the support rod 18 with the same distance L, and the battery cover 16 can be completely removed.

Further, as shown in FIG. 4, ribs 23, 23 are provided at the base end portions of the left and right inner sides of the battery cover 16 in FIGS. 16-1 and 16-2.
A support rod 18 is interposed therebetween to prevent the battery cover 16 from shifting from side to side.
