Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of the operating section of a working machine in which a battery is disposed within the internal space of a frame cover disposed below the driver's seat.

[Conventional technology]

Conventionally, in the structure of the driving part of such a work machine, the battery placed in the internal space of the frame cover is inserted into the upper opening of the frame cover, which is opened by tilting the driver's seat forward, and lifted. The battery was inspected after the battery was removed from the frame cover.

[Problem that the invention attempts to solve]

However, in the conventional structure described above, the heavy battery has to be lifted to take it in and out, which is difficult to operate, and there is also the risk of the battery slipping and dropping.

The present invention has been developed in view of the above-mentioned circumstances, and its purpose is to make it easy to take in and take out batteries.

[Means for solving problems]

The characteristic configuration of the present invention is that an opening for taking in and out batteries is formed in the front wall portion of the frame cover, and a lid body for closing this opening is detachably attached to the frame cover, and the inner surface of the lid body is , a battery cradle placed on the main frame located within the frame cover is arranged in series, and a step is mounted and connected to the main frame in front of the front wall portion of the frame cover at the front end of the battery cradle. The main feature is that a front upward slope is provided for climbing onto the vehicle, and its functions and effects are as follows.

[Effect]

That is, by holding the lid that closes the opening for taking in and taking out the battery formed on the front wall of the frame cover and pulling it out toward the step side, that is, toward the front, you can insert the battery holder connected to the inner surface of the lid. Pull it out on the steps.

At this time, the battery cradle is made to ride onto the step via a front upward slope provided at the front end of the battery cradle.

Further, the battery holder is set by sliding the battery holder which has climbed onto the step onto the frame cover side through the front upward slope.

[Effect of idea]

Therefore, the battery holder can be taken in and taken out by pulling out and pushing the lid, which makes it easier to put in and take out the battery compared to the conventional method of inserting your hand through the opening above the frame cover and lifting it. Now it's safe and easy to do. Moreover, since the battery cradle climbs from the main frame onto the step via the inclined surface of the battery cradle, the operation for climbing on the battery cradle can be carried out easily, and the battery cradle can be tilted. By sliding the battery holder located on the step through the surface, the final pushing operation to the set position on the main frame can be easily performed.

〔Example〕

FIG. 9 shows a riding-type rice transplanter in which a seedling planting device 5 is attached to the rear of the machine body 3, which is equipped with a driving section consisting of a control handle 1, a driver seat 2, etc., via an elevating link mechanism 4. The structure of the operating section will be explained in detail.

As shown in FIGS. 1 to 3, a battery 7 is disposed within the internal space of the frame cover 6 disposed below the driver's seat 2, and the battery 7 is inserted into and out of the front wall portion 6a of the frame cover 6. A lid body 9 that forms an opening 8 for use and closes this opening 8.
is detachably attached to the front wall portion 6a with two bolts 10. On the inner surface of the lid 9, a battery holder 12 is placed on the main frame 11 located inside the frame cover 6.
and a front upward slope 12a for climbing onto the step 13 mounted and connected on the main frame 11 in front of the frame cover front wall portion 6a is provided at the front end of the battery cradle 12, If you want to remove the battery 7, loosen the bolt 10, then insert your hand into the hole 9a formed in the lid 9 that also serves as a handle, and pull it out toward the front via the front upward slope 12a. , battery cradle 1
2 on top of step 13, and
When the battery 7 is pushed into the internal space of the frame cover 6 after the inspection of the battery 7 is completed, the battery holder 12 is inserted through the front upward slope 12a.
By sliding down the battery 7, the battery 7 is positioned at a set position on the main frame 11, so that the battery 7 can be easily taken in and out.

As shown in FIG. 4 and FIG.
4 and 14, and welded and fixed L-shaped members 15 to both ends of the lower surfaces of the step frames 14 and 14. When installing the step 13 to the main frame 11, the brackets 16 and L-shaped members fixed to the main frame 11 are attached. By making it easy to align with the character-shaped member 15 in the front, rear, left and right directions,
The step 13 can be easily assembled to the main frame 11. After the positioning of the fixed bracket 16 and the L-shaped member 15 is completed, the bolts 17 are inserted through the holes 13a, 14a formed in the step 13 and the step frames 14, 14, and the bolts 17 are inserted into the small holes of the bracket 16. 1
The assembly work of the step 13 can be completed by screwing the bolt 17 into the nut 18 welded to the bracket 16 via the bolt 6a.

6 to 8 show the mounting structure of the hydraulic pump 20 attached to the lower surface of the driving unit 19. To explain the mounting structure, the hydraulic pump 20 is keyed to the input shaft 21 and input pulley 22. The shaft ends of the drive shaft 23 are fitted together, and the bearing fitting 24 is fitted into the fitting part between the pump 20 and the stay 25 attached to the lower part of the driving part 19, thereby forming a concentric close fitting part. has been configured. The bearing fitting 24 concentrically fits and supports the input boss portion 20a of the pump 20, and is movable in the longitudinal direction of a long hole 25a formed in the stay 25, and is wound between the pulleys 22 and 26. belt 27
The tension is adjustable. In addition, 25b in the figure,
25b is a bolt insertion hole for fixing the pump 20 to the stay 25.

[Another example]

The present invention can be applied not only to a riding rice transplanter but also to various working machines in which a battery 7 is disposed within the internal space of a frame cover 6 disposed below the driver's seat 2.
