Abstract

PURPOSE:To expose traveling devices from below a working apparatus so as to facilitate maintenance for the traveling device by laterally moving the traveling devices and the working apparatus above that relatively to relatively displace at least one of the right and left traveling devices outside the working apparatus. CONSTITUTION:A machine body frame 5 loaded on a grain threshing apparatus 4 as a working apparatus 2 is framed by connecting front and rear rail frames 6a to each other by right and left square pipes 7a. Traveling devices 1 are formed by wrapping a caterpillar belt 10 round a rolling wheel 9 group supported on a rolling wheel frame 8. In this case, a frame foot 11 provided on the rolling frame 8 is connected to right and left square pipes 13a, 13b for connecting front and rear slide frames 12. Further, the cylinder side of a hydraulic cylinder 15 is connected to the square pipes 7a, and the piston side thereof is connected to the square pipes 13a, 13b to form a traveling device exposing means. The traveling devices 1 are slid by the elongation and contraction of the hydraulic cylinder 15 to be exposed outside the working apparatus 2.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a mobile working machine, such as a combine harvester, in which a working device is provided above a traveling device.

(Prior Art) Conventionally, in a mobile working machine, a working device is provided above left and right traveling devices having wheels and a track belt.

The wheels and endless track belts are positioned so that they do not protrude outwardly from the working device in plan view. This is due to safety and legal and regulatory reasons.

(Problem to be Solved by the Invention) In the above-mentioned conventional mobile work machine, the wheels of the traveling device, the track belt itself, or the support mechanisms for the wheels and the track belt are hidden by the working device above in plan view. It is in the position where it was. For this reason, the upper working equipment gets in the way when performing maintenance on the traveling gear, such as attaching and detaching wheels and track belts, removing mud that has clogged the traveling gear, and repairing the traveling gear when it breaks down. Therefore, maintenance cannot be easily performed.

(Means for Solving the Problems) The present invention takes the following technical means to solve the above problems.

That is, the working device 2 is provided above the left and right traveling devices 1, and by the relative lateral movement of the traveling device 1 and the working device 2, at least one of the left and right traveling devices 1 is moved toward the outside of the working device 2. This mobile working machine is characterized by being provided with a traveling device exposing means 3 for exposing the traveling device.

(Operations and Effects of the Invention) When the traveling device 1 of the mobile work machine requires maintenance, the traveling device 1 and the upper working device 2 are relatively moved laterally to remove at least one of the left and right traveling bags W1. one side,
When viewed from above, the working device 2 is relatively displaced outward. As a result, the upper part of the traveling device 1 is also opened, and mist comes out from the side of the working device 2. As a result, maintenance of the exposed running gear 1, e.g.
It becomes possible to easily perform attachment/detachment work of wheels, endless track belts, etc., removal of mud clogged in the traveling device 1, repair work when the traveling device 1 breaks down, etc.

(Example) An example in which the present invention is applied to a combine harvester as a mobile working machine will be described.

In the first embodiment, as shown in FIGS. 1 and 2, the spacing between the left and right endless track bands can be changed.

The fuselage frame 5 on which the threshing device 4 as the working device 2 is mounted has rail frames 6a, 6b with a U-shaped cross section located at the front and back and running in the left-right direction, and square pipes 7a, 7b located at the left and right and running in the front-back direction. The 6-travel system a21, which is connected to form a frame, has a group of 9 wheels supported on a wheel frame 8 and a track belt 10.

Frame feet 11 are provided diagonally upward from two locations on the front and rear of the wheel frame 8. Furthermore, the front and rear slide frames 12.degree. 12 extending in the left-right direction are connected by left and right square pipes 13a and 13b, respectively. and,
The frame foot 11 is connected to the square pipes 13a and 13b from above.

Further, a plurality of support rollers 14 are attached to the slide frame 12, and the support rollers 14 are attached to the rail frame 6.
Insert from the open side of a and 6b. As a result, the slide frame 12 can be moved to the rail frames 6a, 6b.
The structure of 0 or more in which the wheel frame 8 slides in the left-right direction along the left-right direction, and as a result, the wheel frame 8 is slidable in the left-right direction is applied symmetrically to the left and right traveling devices 1.1. In addition, 15 is a hydraulic cylinder, and the cylinder side is connected to the square pipes 7a and 7b, respectively, and the piston side is connected to the square pipes 13a and 13b, respectively. (The above configuration is the traveling device exposing means 3.

With the above configuration, the traveling device 1 slides by the expansion and contraction of the hydraulic cylinder 15, and when the hydraulic cylinder is extended to its longest state, the endless track belt 10 is displaced outward from the square pipes 7a and 7b. The state will be as follows. This is the traveling device 1.

When viewed from above, the working device 2 (in this case, the threshing device 4) is in a state where mist is coming out outward.

In the second embodiment, as shown in FIGS. 3 and 4, a working device 2 (a reaping section A, a parking assisting section, a grain tank C1, a threshing device 4, etc.) is provided above a traveling device 1 that is integrated on the left and right sides. It is configured to be able to slide freely in the left and right directions.

Support members 17 are arranged in the left-right direction on the front and rear sides of the body frame 16 on which the threshing device 4 as the working device 2 is mounted.
．． 17. Attach 17. The support member 17, 17.1
Among the rollers 7, those located on the right side and the left side are provided with support rollers 18, 18 having axes in the front and rear directions, respectively.

Further, a gear 20 driven and rotated by a hydraulic motor 19 is provided at a portion of the support member 17 located substantially in the center in the left-right direction.

The traveling device 1 has, as described above, a group of 9 wheels rotatably attached to a wheel frame 8 and an endless track belt 10 mounted thereon. And the left and right wheel frames 8,8.

The left and right traveling devices 1, 1 are integrally connected by front and rear frame feet 21, 21. Furthermore, left and right slide rails 22, 22 are fixed to the upper portions of the frame feet 21, 21. The slide rail 22 has a U-shaped cross section with one side open, and a rack 23 that engages with the gear 20 is provided at the upper inward direction.

Then, the support rollers 18, 18 and the gear 20 are inserted into the slide rails 22, 22.

Thereby, the body frame 16 is configured to slide in the left-right direction with respect to the slide rails 22, 22. (The above structure is the traveling device exposing means 3.) With the above structure, the support roller 18 supports the weight of the working device 2 in contact with the lower inner surface of the slide rail 22, and the gear 20 supports the rack 23. By rotating in a state where the working device 2 is engaged with the traveling device 1, the working device 2
Slide left and right against. By this sliding, in plan view, among the left and right traveling devices 1, 1,
Either one can be exposed to the outside of the working device 2.
