Abstract

PURPOSE:To facilitate the loading work of a working machine onto the loading bed of a truck by constituting a transport vehicle from a belt meshed with the crawler belt of the working machine. CONSTITUTION:A transport vehicle has a rotatable axle 13 for traveling wheels 4 consisting of the right and left front and rear wheels in pairs onto a car base 3, and an endless belt 6 is laid between the sprockets 14 installed onto the axle 13. When a working machine 1 is loaded onto the transport vehicle, the crawler 5 of the working machine 1 is received by the upper surface of the endless belt 6, and the machine body 2 is fixed onto the car base 3. The lugs 15 and 16 of the crawler 5 and the endless belt 6 are meshed with each other. Therefore, the transport vehicle can be traveled by steering-operating the working machine 1, and the working machine 1 can be easily loaded onto the loading bed of a truck.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a transport vehicle equipped with a working machine such as a combine harvester having a crawler-type traveling device.

Conventional technology and problems to be solved by the invention Work machines with crawlers, such as combine harvesters and bulldozers, are often carried on trucks when they are transported on the road. is not easy and can be dangerous.

Means for Solving the Problems This invention provides a chassis (3) on which a working machine (1) is mounted and which fixes the movement of this machine body (2), with a pair of left and right running wheels (4).
), and left and right endless bands (6) are provided on the upper side to receive crawlers (5) disposed on the left and right sides of this working machine (1), and are rotationally driven to transmit power to the opposing running wheels (4). The construction of the work equipment carrier is as follows.

Effects of the invention When mounting the work machine (1) on the transport vehicle, this work a (1)
) on the upper surface of the endless band (6),
This body (2) is fixed to the chassis (3) so that it cannot be moved in the longitudinal direction. When transporting, the vehicle platform (5) that receives the crawlers (5) is mounted on the work It (1) and drives the left and right crawlers (5) by transmission operation in the same manner as when the work machine (1) is traveling. The endless belt (6) of 3) is rotated, and the crawler (5) on one side is rotated by the steering operation of the zero work machine (1), which travels on the road by transmission rotation of the left and right wheels (4). When the power transmission is cut off, the endless belt (6) and the wheel (4) on this side will be in the same state, so the wheel (
4) Steering during driving is performed.

When the working machine (1) is to be lowered after being transported, the machine body (2) is unfastened from the chassis (3).

In this way, the transport vehicle is a crawler (5) with a work capacity of 4 tons (1).
This aircraft (
2) is fixed to the chassis (3), the vehicle can be driven by the wheels (4) of the transport vehicle by operating the work equipment (1), and the vehicle is driven by the engine as its sole power source. There is no need to provide a transmission device or the like, the structure is simple, the chassis (3) can be made low, and the vehicle can be driven quickly on the road.

Embodiment In the illustrated example, one working machine (1) is a combine harvester, and a pair of left and right crawlers (5) is provided at the bottom of the machine body (2).
The engine is installed under the driver's seat (7) and is configured to drive the crawler (5) by transmitting power to the left and right travel shafts (9) via a travel transmission device (8). Also, this traveling transmission! (8) is provided with a steering transmission mechanism such as a steering clutch, and can be operated by operation from the steering bag 21 (10). (11) is a reaping device on the front side of the machine body (2), and is configured to transfer and supply the husk to be harvested to the threshing device a (12) on the rear side for threshing processing. The cockpit (7).

and a control device (10) at the rear of this reaping device (11).
It is placed on the side.

The transport vehicle has an axle (13) of running wheels (4) consisting of a pair of left and right front wheels and a rear wheel rotatably provided on a chassis (3), and sprockets (14) provided on the front and rear axles (13).
), an endless belt (6) is placed between the two wheels, and the rotating diameter of the endless belt (6) is smaller than the diameter of the running wheels (4), so that it does not touch the ground.

The left and right spacing between the left and right endless bands (6) is the same as the spacing between the left and right crawlers (5) of the working machine (1), and the outer circumferential surface is designed to interlock with the lugs (15) of the crawlers (5). Matching rug (1B
) to ensure transmission of power from the crawler (5) to the endless band (6) without slipping.

At one end of the chassis (3), an inclined surface (17) that faces the front of one end of the endless band (6) and slopes forward and downward is provided,
The crawler (5) may be configured to be easily loaded and unloaded (Fig. 2), and locking devices (18) may be provided protruding from the front and rear ends of the chassis (3). , combine harvester work equipment (1
The hooks (19
) can be engaged. This hook (18) is
By rotating the lever (20) provided on a part of the body (2), the connecting rod (21) can be used to rotate both the front and rear at the same time, and each hook (18) can be engaged and disengaged from the locking tool (18). Let it happen.

The combine harvester work is performed by driving the engine to transmit various parts such as the crawler (5), reaping device (11), and threshing device (12).It is operated by the operator sitting on the cockpit (7). When the pair of left and right crawlers (5) are transmitted and rotated by operating the control device (lG), the vehicle is in a straight running state, and when steering is performed, the transmission is cut off from the crawler (5) on the turning side. To stop traveling, use the left and right crawlers (
5) by cutting off the power transmission and further applying the brake.

When this combine harvester is transported on the road, it is mounted on a transport vehicle. When mounted, the left and right claws (5) are placed in such a way that they can be received by the upper surface of the endless belt (6), and the lugs (15) and (1B) are interlocked with each other, the operator is seated in the cockpit (7), and when moving forward, the crawler (
5) can be used as a reverse gear to transmit rotation, similar to the traveling operation of the combine harvester described above. In this case, the reaping device (1
1) And threshing equipment! ! (12) etc. are not carried out, and the transmission of this crawler (5) is carried out at variable speed transmission in a high speed range, thereby allowing the transport vehicle to travel at high speed.
