Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a battery mounting portion in a working vehicle in which the battery is mounted on a mounting base that is detachably mounted on the body of the vehicle.

[Conventional technology]

As shown in, for example, Japanese Utility Model Application No. 51-27825, the above-mentioned work vehicle supports the battery itself by inserting the hand deep into the battery storage space, even if there are other devices in front of, in front of, or above the battery. Even if the battery is not installed, the battery can be easily loaded and unloaded by pulling out or pushing in the battery mounting base near the battery loading/unloading port.

Conventionally, in this type of work vehicle, the connection for fixing the battery mount to the machine body and the connection for connecting the cathode side cord of the battery to the machine body have been made separately, which has the following disadvantages.

[Problem that the invention attempts to solve]

In other words, it is necessary to separately provide a structure for fixing the battery mounting base to the fuselage and a structure for connecting the battery cathode to the fuselage, which is not only disadvantageous in terms of structure, but also makes loading and unloading of the battery difficult. For this purpose, the operation for connecting and uncoupling the battery mount to the aircraft body,
Each operation for connecting and disconnecting the battery cathode to the aircraft body had to be performed separately, which was time-consuming.

The purpose of the present invention is to make fixing and unfixing of the battery mounting base, and connecting and disconnecting the battery and the aircraft body easy, both in terms of structure and operation.

[Means for solving problems]

The feature of the present invention is that, in the structure of the battery mounting portion of the above-mentioned work vehicle, the cathode side cord of the battery and the mounting base are connected to the body using the same connector that can be freely operated for release. The functions and effects are as follows.

[Effect]

When the connector is operated to a released state, the battery mount is released from being fixed to the aircraft, and
The battery becomes disconnected from the aircraft, and when the connector is operated to the connected state, the battery mounting base becomes fixed to the aircraft and the battery is connected to the aircraft.

In order to simplify the operation for coupling and uncoupling, if the battery cathode side cord is connected to the battery mount and connected to the aircraft via the battery mount, when loading and unloading the battery, the sliding If the battery mount starts to lift up, there is a risk of sparks between the battery mount and the aircraft. However, according to the present invention, when loading and unloading the battery, the battery and the aircraft are not connected, so
Spark generation can be avoided.

[Effect of idea]

By connecting or uncoupling the battery mount and connecting or separating the battery to the aircraft body, it is possible to fix the battery and connect it to the aircraft body using the same connection configuration, simplifying the structure. In addition to being able to perform sliding operations while supporting the battery, loading and unloading the battery is easy and quick in terms of operations for connecting and disconnecting the battery mounting base and the battery from the aircraft. Now I can do it. Moreover, since there is no risk of spark generation, it can now be done safely.

〔Example〕

As shown in FIG. 4, a pair of left and right wheels 1, 1,
A rotary tilling device 6 is connected to the rear of a traveling machine body having an engine 4, a control handle 5, etc. mounted on a body frame 3 and located in front of the transmission case 2 to which the wheels 1 are attached. The structure is such that power is transmitted from the transmission case 2 to the tilling device 6, thereby configuring a walking type tiller.

As shown in FIGS. 1 and 2, an engine starter (not shown) and a rotary tiller 6
A motor 8 that raises and lowers the ground tail wheel 7 for adjusting the plowing depth.
The battery 9 as a power source of the engine 4
The fuselage frame 3 is placed between the transmission case 2 and the transmission case 2, and is placed in the box-shaped battery case 10 and fixed with the fixture 11.
It is installed on.

As shown in FIGS. 1 and 2, the battery case 10 is placed on the fuselage frame 3 so that it can be slid in the lateral direction of the fuselage, and a case locking device is fixed to the fuselage frame 3. An engaging part 13 is provided at one lateral end of the battery case 10 so as to be removably engaged with the battery case 12 in the lateral direction of the fuselage. A lock bolt 16 as an example of a connector attached across the bolt attachment portion 14 and the bolt attachment portion 15 of the fuselage frame 3
are releasably connected and fixed to the fuselage frame 3 by each of them. In order to connect the cathode 17 of the battery 9 to the fuselage, a cord 18 extending from the cathode 17 is connected to the fuselage frame 3 with the battery case 10 tightened together with the lock bolt 16.

In short, by locking or unlocking the lock bolt 16, the battery case 10 is fixed to the fuselage frame 3 and the battery 9 is connected, or the battery case 10 is fixed to the fuselage frame 3 and the battery 9 is disconnected. As shown in FIG. 3, the battery case 10 can be removed by pushing it in or pulling it out while sliding it against the fuselage frame 3 from the outside side of the fuselage with the hand 19 holding the battery case 10. 9 can be loaded and unloaded while disconnected from the fuselage frame 3.

[Another example]

In addition to walk-behind tillers, the present invention can also be applied to various work vehicles such as riding agricultural tractors, combine harvesters, binders, transport vehicles, and construction vehicles.

The battery case 10 may be replaced with a frame-type or plate-shaped battery mounting stand, and these are collectively referred to as the battery mounting stand 10.
