Abstract

PROBLEM TO BE SOLVED: To provide the traveling device of a combine harvester or the like for facilitating the detachment of a traveling crawler and improving operability by forming a prescribed gap in a side face view between a traveling crawler outer peripheral upper surface part and a step supporting body lower surface part and forming a step supporting body at a non-overlapping relational position. SOLUTION: In the combine harvester provided with a threshing device for threshing reaped grain culms on the upper part of a traveling car body 5 and the traveling crawler 8 or the like rotationally driven to travel on a lower part, the prescribed gap is formed in the side face view between the outer peripheral upper surface part of the traveling crawler 8 and the lower surface part of the supporting body 7 provided on the front part of the traveling car body 5 where a pilot steps on and gets on the combine and the step supporting body 7 is formed at the non-overlapping relational position.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a step support which is mounted on a traveling vehicle body and which is positioned so that the lower surface of the step support and the upper surface of the outer periphery of the traveling crawler do not overlap with a predetermined gap in a side view. The present invention relates to a traveling device such as a combine formed and provided.

[0002]

2. Description of the Related Art A harvesting operation of a grain stalk by a combine is performed by an operator who steps on a step support provided on a traveling vehicle body and performs various operations.
The traveling crawler rotates and travels, and the harvested culm harvested is supplied to a threshing device for threshing.

When replacing the traveling crawler, the combine is tilted to one side and the traveling crawler portion is floated, or the entire combine is suspended and the traveling crawler portion is lifted and replaced.

[0004]

The lower surface of the step support and the upper surface of the outer periphery of the traveling crawler are provided in such a manner that the step support is mounted on the traveling vehicle body so as to be overlapped in a side view. However, when removing the traveling crawler, the outer peripheral upper surface portion of the traveling crawler abuts on the step support, and it is difficult to remove the traveling crawler.
It is intended to facilitate removal.

SUMMARY OF THE INVENTION The present invention provides a vehicle
A threshing device 4 for threshing a harvested grain culm at the upper part and a combine crawler provided with a traveling crawler 8 and the like driven to rotate and travel at a lower part are provided on an outer peripheral upper surface part of the traveling crawler 8 and a front part of the traveling vehicle body 5. A predetermined gap in side view with the lower surface of the step support 7 on which the operator steps on the combine
The step support 7 is formed and provided at a position where it does not overlap with the step support 7 to provide a traveling device such as a combine.

[0006]

In the harvesting operation of the grain culm by the combine, the operator steps on the step support 7 provided on the traveling vehicle body 5 and performs various operations, whereby the traveling crawler 8 is driven to rotate. The harvested culm that travels and is cut is supplied to the threshing device 4 for threshing.

When replacing the traveling crawler 8, the combine is inclined to one side and the traveling crawler 8 is lifted, or the entire combine is lifted and the traveling crawler 8 is lifted and replaced.

[0008]

The lower surface of the step support 7 and the upper surface of the outer periphery of the traveling crawler 8 have a predetermined gap (a) in a side view so that the step support 7 is positioned so as not to overlap. When the traveling crawler 8 is removed, the outer peripheral upper surface portion of the traveling crawler 8 does not come into contact with the step support member 7 and can be easily removed.

An embodiment of the present invention will be described below with reference to the drawings. The combine 1 in the figure has a configuration including a traveling device 2, a mowing device 3, a threshing device 4, and the like, and the combine 1 will be described. The traveling device 2 is provided with a pair of left and right traveling crawlers 8 that travel by rotating and driving the soil surface below the framed traveling body 5. On the frame on the right side of the traveling body 5, step supports 7, 7 of a predetermined width, both upper and lower ends of which are bent inward, are provided at predetermined intervals in the left-right direction, and protrude forward by a predetermined length. Provided. A step plate 6 is directly mounted on the upper ends of the step supports 7, 7 in order to reduce costs. When the operator boards the combine 1, the operator steps on the step board 6 and sits on a cockpit 8 a, which will be described later.

The lower end of the step support 7 and the upper end of the outer periphery of the traveling crawler 8 are provided with a predetermined gap (a) in a side view as shown in FIG. 7, 7 are formed and mounted on the traveling vehicle body 5. When the traveling crawler 8 is removed, the upper end of the outer periphery of the traveling crawler 8 does not come into contact with the step support 7, so that the removal is facilitated.

On the front frame on the front side of the traveling vehicle body 5, supporting rods 9, 9 of a predetermined length are mounted to be inclined forward and upward, and a transmission mechanism (not shown) is mounted by the supporting rods 9, 9. This is a configuration for supporting the traveling mission case 10. Crawler receiving frames 12, 12 are provided on both left and right sides of the middle frames 11, 11 of the traveling vehicle body 5, and these crawler receiving rods 1 on both sides are provided.
Crawler support frames 13 and 13 are provided at the outer ends of the two and 12, respectively.

A sprocket 15 pivotally supported by an axle 14 protruding on both left and right sides of a traveling transmission case 10 mounted on a front end of the traveling vehicle body 5 and a receiving shaft 16 protruding from a rear end of a crawler support frame 13. The traveling crawler 8 is stretched and stretched between the rear wheel 17 that is pivotally supported and each of the idle vehicles 19 that are pivotally supported by a plurality of receiving shafts 18 protruding from an intermediate position in the front-rear direction.

An operation device 21 provided with various operation levers 20 and the like is provided on the front side of the step plate 6. A pilot seat 8a is provided on the rear side of the step board 6 and above the traveling vehicle body 5 to carry out operation control such as a traveling operation, a harvesting operation, and a threshing operation while the operator is on board.
