Description

[Detailed Description of the Invention] If the component parts are molded from synthetic resin or the like in order to reduce the manufacturing cost and weight of an instrument control panel for a mobile agricultural machine, the desired strength may not be obtained.

In such a case, if the stay for reinforcing the instrument control panel and the safety of the operator are made separate, the cost will increase, and if the stay is formed into a gate shape for both reinforcement and safety, the operating range of the operating lever will be limited by the stay. Not only is this restrictive, but even if the operator tries to grab onto it in an emergency, there is a risk of being thrown off as there is no part to hold onto, and furthermore, the reinforcing effect cannot be expected to be that great.

This invention protects the control panel and ensures the safety of the operator, and can be obtained at a low cost.In addition, in an emergency, it is easy to grab and will not fall off, and the forward field of vision and control lever operation range are wide. The purpose of this invention is to provide a stay for the driver's seat of a mobile agricultural machine.

An example of applying the present invention to a combine harvester will be explained with reference to the drawings. In FIG. A paddy distribution device 5a is provided at the upper end opening of the grain lifting machine 5 of the threshing machine 4 mounted above, and a paddy bag for storing the paddy flowing out from the paddy distribution device 5a is provided on the paddy receiving stand 6a below the paddy distribution device 5a. 6 is suspended by a hanging rod 6b.

Further, a seat 10 is provided immediately behind the instrument operation panel 8 provided on the driving frame 7, and a driver's seat cover 9 is provided on the side thereof.

A pair of pillars 11b, 11b made of pipes are erected on the operating frame 7 on both sides of the instrument operation panel 8,
The stay A is composed of a horizontal support rod 11a made of a pipe, and the horizontal support rod 11a has a horizontal support portion a along the upper front side of the instrument operation panel 8, and both ends thereof are bent upward. Once raised, the rising portion is then bent rearward, and the distal end thereof is sequentially curved from below to the front.
The vicinity of the upper end of the rising portion S,b, that is, the rearward portion following it, is welded to the upper ends of the pair of left and right columns 11b, llb, and the lower end of the rear protruding portion C is welded to the upper end of the pair of left and right columns 11b, llb.
It is welded to the rear surface of the middle part of lb.

Further, the inner end of the connecting rod 11c, whose outer end is welded to the inner side of the intermediate portion of the supports 11b and llb, is fixed to the outer surface of the instrument operation panel 8 by the mounting seat 12 and the pole 13.13.

Further, the seat 10 is supported by a pantograph-shaped mounting seat 14, the front part of which is connected to a front pivot 14a of the mounting seat 14, and the rear part thereof connected to a top plate 14b.

When the seat 10 is to be raised and operated in a standing position, the adjustment rod 15, which is inserted so as to rotate at a fixed position on the front pivot 14a and screwed into the rear pivot 14c, is rotated. When the seat 10 is raised, the rear part of the seat 10 is raised more than the front part, so that the seat 10 rises and stands up in a forward leaning position as shown by the dotted lines in FIGS. 1 and 3.

Therefore, the robot can be operated in a standing position in an extremely stable state while leaning backwards as shown in FIG.

In addition, in the drawing, 16 is a mounting seat, 17 is a steering lever, 18 is a speed change lever, 19 is a hydraulic lever, 20 is a continuously variable speed lever,
21 is a pre-processing lever, 22 is a working machine lever, and 23 is a cutter switching lever.

The stay of the present invention does not obstruct the forward view along the upper front side of the instrument operation panel, but
Both sides are bent diagonally backward and upward at a portion close to the outer side of the instrument operation panel, and then the ends thereof are bent diagonally forward and downward into an arc shape, and the ends are bent diagonally forward and downward to form a curve behind the instrument operation panel. By protruding to the side, it is possible to comfortably grasp the curved portion and operate the vehicle in a natural and comfortable posture, whether seated or standing, and with the hand extended obliquely from behind and above.

Furthermore, even if the machine body suddenly tilts laterally when working in an upright position, the curved part protruding rearward from the instrument operation panel acts as a handrail to prevent the machine from being thrown off. Can be done.

Further, the horizontal frame rod and the column constitute a framework in which the middle portion of the upper portions of both sides of the horizontal frame rod and the end portion of the portion bent toward the front and downward are integrally fixed to the upper portions of the pair of columns. As a result, the strength can be increased, and the sides of the instrument operation panel and the control section can be covered to improve safety.

Claims (1)

[Scope of utility model registration request] A pair of supports are erected on both sides of the instrument control panel of the control section of the mobile agricultural machine, and both sides of the horizontal horizontal rod, which is made of a pipe and is approximately horizontal, are once diagonally rearward at a portion close to the outside of the instrument control panel. Bend it upwards, then bend the end diagonally forward and downward in an arc shape so that it protrudes beyond the instrument operation panel, so that the horizontal part of the transverse frame is bent so that its approximately horizontal part is above the instrument operation panel. A stay for a driver's seat in a mobile agricultural machine, which is arranged along the front surface of the upper part and integrally fixes the middle part of both upper parts and the end part of the part bent forward and downward to the upper part of the pair of supports.
