Operator's Seat of Work Vehicle

Abstract

The present invention aims to increase the storability around the operator's seat and reduce labor for reverse rotation in a work vehicle in which the operator's seat is formed to be reversely rotated. The operator's seat support member is disposed on the machine frame of the work vehicle so that the operator's seat can be rotated on the support member, hydraulic hoses are held along the side face of the support member, a storage part rotated together with the operator's seat is installed on the front lower seat surface of the operator's seat, and that the rotating center axis of the operator's seat at the sliding center of the operator's seat is approximately on the seat index point of the operator's seat.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a structure of a rotatable seat arranged in a work vehicle.[0003]2. Background Art[0004]A work vehicle called Backhoe Loader is conventionally known in which a front loader is attached to the front part of the tractor vehicle body, and a backhoe is attached to the back part.[0005]In such work vehicle, a seat frame is generally formed into a box shape, and access to under the seat frame in time of maintenance is made by removing the cover configured into a great number of layers. The space under the seat is formed narrow since the seat frame is a box shape.[0006]Furthermore, a storage part for storing instruction manual and the like is installed on the back surface of the operator's seat or on the side of the seat in the conventional work vehicle.[0007]Patent document 1 discloses one example of an operator's seat of the backhoe loader.[0008]In the backhoe loader disclosed in the relevant ...

AI Technical Summary

Benefits of technology

[0017]In an operator's seat of a work vehicle of the present invention, an operator's seat support member is disposed on a machine frame of the work vehicle so as to be rotatably formed on the support member, and a storage part rotated together with the operator's seat is installed on a front lower seat surface of the operator's seat, and thus access to the storage part from the sitting state is facilitated irrespective of the position of the operator's seat.

[0018]Furthermore, in an operator's seat of a work vehicle of the present invention, an operator's seat support member is disposed on a machine frame of the work vehicle so as to be rotatably formed on the support member, a seating surface of the operator's seat is slidable towards the front and the back, and a rotating center axis of the operator's seat at the central position of the slide of the operator's seat is approximately on the seat index point of the operator's seat, and thus the stricture of the operator's seat is simplified, and the assembly property of the operator's seat and the support member is enhanced. The access to under the operator's seat is facilitated, and the operator's seat can be rotated while sitting thereon through a natural operation when rotating the driver's seat.

[0019]Moreover, in an operator's seat of a work vehicle of the present invention, an operator's seat support member is disposed on a machine frame of the work vehicle so as to be rotatably formed on the support member, and holding parts of hydraulic hose are installed on the support member to hold the hydraulic hose along the side face of the support member, and thus replacement of the hydraulic hose of the work machine is facilitated, and maintenance of the hydraulic path is enhanced.

Problems solved by technology

Piping cannot be arranged in the vicinity of the operator's seat since the operator's seat is reversely rotated by a complex mechanism.

However, in the tractor disclosed in patent document 1, the space between the operator's seat and a safety frame is narrow, it is troublesome when the operator reversely rotates the operator's seat and again sits on the operator's seat, and a great amount of trouble is needed when reversely rotating the operator's seat.

Furthermore, taking out from and putting in to the storage part become difficult if the storage part is arranged around the operator's seat or on the back surface of the operator's seat.

If the storage part is arranged on the side of the operator's seat, there is a possibility that the storage part may be missed when reversely rotating the operator's seat.

If the storage part is arranged on the back surface of the operator's seat, taking out from and putting in to the storage part become difficult.
