Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a cabin of a work vehicle such as a wheel loader or a riding lawn mower.

[0002]

2. Description of the Related Art In a wheel loader, a cabin is provided so as to cover a driving part and a driving part because a driver's seat is arranged on the driving part. And, for example, the actual Kaihei 2-
As shown in Japanese Patent Publication No. 96275, in this cabin,
The structure is provided with a swingable door that opens and closes an entrance / exit to and from the driver, and a wall portion that is located on the lateral outer side of the driving part and behind the door.

[0003]

However, during maintenance of the driving part, the driving part located on the other side of the fixed wall portion from the entrance / exit has to be treated, which makes maintenance work difficult and maintenance of the driving part is difficult. There was room for improvement in terms of workability.
An object of the present invention is to make it possible to easily perform maintenance work on a driving part without being obstructed by a wall portion.

[0004]

A characteristic structure of the present invention is that a cabin that covers a driving part and a driving part, a swingable door that opens and closes an entrance / exit of the driving part, and a door on the lateral outer side of the driving part. In a work vehicle having a wall portion located at the rear, the wall portion is attached together with a door so as to be openable and closable in an openable state.

[0005]

That is, at the time of maintenance of the prime mover, the wall portion located laterally outward of the prime mover can be opened together with the door. Therefore, the maintenance work can be performed by using the wide opening formed by the opening of the wall portion and the entrance / exit. Can be performed easily.

[0006]

As a result, it has become possible to provide a work vehicle which is further excellent in maintainability and which can easily perform maintenance work of the prime mover without being obstructed by the wall portion of the cabin.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a front body 1 and a rear body 2
Is connected by a hydraulic cylinder 3 so that the waist can be bent and steered freely.
The front vehicle body 1 is provided with a shovel device in which a bucket 6 is rotatably mounted by a hydraulic cylinder 7 on an arm 5 which is vertically swingable by a hydraulic cylinder 4, and a driving portion 8 and a driving portion 9 are provided on a rear vehicle body 2. A wheel loader with a backhoe, which is an example of a work vehicle, is configured by being provided in a state of being covered with the cabin 10 and by being detachably provided with a backhoe device 13. Swing-type door 10 for opening / closing the entrance / exit for the driver's part 8
a and a wall portion 10b located laterally outside of the driving portion 9 and behind the door 10a are provided in the cabin 10, and as shown in FIG. 2, slide rails 12 slide back and forth on upper and lower fixed rails 11 respectively. Freely attached, the wall portion 10b is attached to the slide rail 12, the door 10a is integrally slidably and swingably attached to the wall portion 10b, and the wall portion 10b can be opened / closed together with the door 10a in an openable state. Then, the wall portion 10b is opened together with the door 10a to form a wide opening so that the maintenance work of the driving portion 9 can be easily performed.

To form the backhoe device 13, a swing bracket is attached to a mounting frame having an operating portion and a pair of left and right outriggers 13a so as to be rotatable left and right by a hydraulic actuator, and a boom is freely swingable up and down by a hydraulic cylinder. Attached to a swing bracket, an arm 13b attached to a boom so as to be swingable by a hydraulic cylinder, a bucket 13c attached to an arm 13b so as to be rotatable by a hydraulic cylinder, and a chain 15 with a hook 14 attached to an upper portion of an outrigger 13a. Thus, the backhoe device 13 in the retracted posture, which is moved to the cabin 10 side, is configured to be steady by the chain 15 in which the hook 14 is hooked on the arm 13b. Step 16 for entrance / exit
3, the left and right plate-shaped suspension members 16a are swingably attached to the rear body 2 around the support shafts 16b, and the lower ends of both suspension members 16a are relatively swingable around the support shafts 16c. The step plate 16d is attached to the step 16 so that the step 16 will not be damaged by the backward swinging motion around the support shafts 16b and 16c even if the step 16 collides with another object during traveling.

[Other Embodiment] To attach the wall portion 10b together with the door 10a in an openable state so as to open and close freely, as shown in FIG.
As shown in FIG.
b, the door 10a is swingably mounted around the support shaft 18, or the door 10a is swingably mounted around the support shaft 19 and the wall portion 10b around the support shaft 20 as shown in FIG. The specific configuration can be changed appropriately. The type of the wheel loader can be appropriately selected such as a type without the backhoe device 14 and a type in which the rear wheels are turned to steer.
It can also be applied to riding lawn mowers.

It should be noted that although reference numerals are given in the claims for convenience of comparison with the drawings, the present invention is not limited to the structures of the accompanying drawings by the entry.
