Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery clamp device for a work vehicle or the like.

[0002]

2. Description of the Related Art Conventionally, a battery clamping device for a work vehicle such as a tractor has a battery fixed on the machine body as shown in Japanese Utility Model Publication No. 56-164852, and a connecting terminal is fastened to the machine body with a bolt to connect the battery terminal. (electrode)
There was one that connects the battery circuit elastically with the battery circuit.

[0003]

However, although the fastening and fixing of the battery clamp device with the bolt and the connection of the battery terminal are performed at the same time, the work of removing the battery for loosening the bolt becomes complicated, and a tool is required for the removal. Due to inconvenience, etc., forget to remove the cord of the battery circuit due to forgetting to release the clamp, especially for work vehicles etc. that are often stored for a long time without use, install it with the circuit connection state Due to this, there was a problem that the battery often runs out.

[0004]

SUMMARY OF THE INVENTION A battery clamp device according to the present invention for solving the above problems is provided with a locking tool 17 for removably fixing a battery 11 on a machine body 1 of a working vehicle. In the above, the engaging member 21 is provided with an engaging portion 21 that engages and disengages with at least one electrode 18 of the battery 11 when the battery 11 is engaged and disengaged, and connects or disconnects a circuit with the electrode 18. It is characterized in that clamp engaging / disengaging tools 27, 31 for engaging / disengaging the clamps are provided between the machine body 1 and the locking tool 17 by a single operation.

[0005]

By the above mechanism, the battery 11 on the machine body 1
It is possible to perform the engaging / disengaging operation of the clamp and the connection with the battery terminal 18 simultaneously and extremely easily by a single operation of the clamping engagement / disengagement tools 27 and 31, and to prevent forgetting to remove the cord of the battery circuit. In particular, in a work vehicle or the like that is often stored in a unused state for a long period of time, the battery 11 is prevented from running down due to being installed while the circuit is connected.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment shown in FIG.
Shows an overall side view of the tractor. The traveling machine body 1 has a machine body frame 2 supported by front and rear wheels 3 and 4, and a radiator 9 in front of an engine 8 in a hood 7 in front of a driver's seat 6.
However, in front of it, a box-shaped battery 11 is in the fuselage 1.
It is installed and placed on top.

2 to 4, the battery 11 has a bottom plate 12 and a side plate 13 integrally fixed to each other in an angle shape, and reinforcing ribs 14 fixed to a corner where the both cross each other. The battery mounting base 16 is stored and mounted on the base 16, and is detachably mounted on the machine body 1 side by bolting or the like.

Further, on the side plate 13 of the battery mounting base 16, there is provided a locking member 17 having a side plate 17a and a top plate 17b which form an angled cross section when viewed from the front and which covers the upper outer end of the battery 11. The top plate 17b has one electrode (ground electrode) 1 projecting from the upper surface of the battery 11.
8 is a ring-shaped connecting portion 21 provided with a fitting hole 19 for fitting
Is attached.

The electrode 18 and the fitting hole 19 are formed in a taper adapted to each other, and the locking member 17 is placed over the outer end portion of the battery 11 from above to form the electrode 18.
Is a mechanism that is grounded via the connecting portion 21 and the locking member 17, and has a tapered structure of the electrode 18 and the fitting hole 19, and between the top plate 17b and the upper surface of the battery 11 at the time of connection. The clearance 22 has a structure that ensures the circuit connection.

On the outer surfaces of the side plate 13 of the battery mounting base 16 and the side plate 17b of the locking member 17, upper and lower protrusions 23 and 24 are provided, respectively, and the lower protrusion 23 has a pin 26 interposed therebetween. The upper end of the engaging / disengaging lever 27 is pivotally supported.

Two elastic members 31 made of coil springs are provided at the front and rear protruding ends of spring engaging pins 28 and 29 provided in the front and rear direction on the shaft support end side of the lever 27 and the upper protrusion 24. Has a structure in which the battery mounting base 16 and the locking tool 17 are connected via the elastic member 31.

With the above mechanism, the battery mounting base 16
For the battery 11 inserted and placed in the regular position above,
The connection member 21 is connected to the electrode 18 so that the locking member 17
When the lever 27 is rotated in the clockwise direction (downward) with the cover covered with the spring (elastic member) 31 to a position beyond the lever rotation fulcrum (pin) 26 (see FIG. 5), the locking member 17 Is positioned by fitting with the electrode 18, and elastically presses and fixes the battery 11 to the battery mounting base 16 side by the elastic member 31. On the contrary, when the lever 27 is rotated counterclockwise and the elastic member 31 crosses the fulcrum (pin) 26 in the opposite direction, the fixing of the battery 11 on the body 1 is released and the ground electrode 18 is also grounded. It is released (open circuit).

Grounding of the earth electrode 18 to the body 1 side in the above embodiment is performed via a spring (elastic member) 31, but as shown in FIG. And the clamp engaging / disengaging device (lever 27, elastic member 3) may be connected separately.
The connection and disconnection of the electrode by 1) is not always the ground electrode (cathode)
Not limited to

[0014]

As described above, according to the present invention, the operation of engaging and disengaging the battery clamp on the machine body and the connection with the battery terminal can be performed simultaneously by a single operation, so that both operations are easy. In addition, it is easier to remove than the conventional bolt tightening type, so it is possible to prevent forgetting to remove the cord of the battery circuit,
Particularly in a work vehicle or the like, which is often stored unused for a long period of time, there is a great advantage that the battery is prevented from running down by being installed while the circuit is connected.
