DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine harvesting frame supporting device for supporting a cutting frame having a cutting device on a vehicle body.

[0002]

The mowing support bracket for supporting the mowing frame of the combine so as to be able to move up and down is generally constructed at the front of the vehicle body and below the grain culm transporting section of the mowing device. Since the transmission mechanism of each part interlocking with the traveling device, the mowing device, and the threshing device is arranged in the portion, the configuration is complicated, and it is easy to hinder the conveyance of the grain stalk. Conventionally, there is a mode in which a traveling transmission case is provided in the front part of the vehicle body and a mowing support bracket is provided in an upper portion of the transmission case. However, a mode in which the support position of the mowing support frame is lowered is not suitable. The space of the transmission mechanism is limited by the case, and it is difficult to perform maintenance.

[0003]

According to the present invention, a cutting support bracket 3 for supporting a cutting frame 2 so as to be able to move up and down is provided on a front upper part of a front portion of a vehicle body 1, and a rear lower portion of the cutting support bracket 3 is provided at a rear lower part. Threshing having a counter transmission case 6 having a main counter shaft 5 transmitted from an engine E mounted on the other side, and a threshing counter shaft 8 receiving transmission from the main counter shaft 5 and transmitting to a threshing device 7 The combine harvester support device is configured to support the counter transmission case 9.

[0004]

The mowing frame 2 supported by the mowing support bracket 3 is raised and lowered on the front portion of the vehicle body 1.
The mowing support bracket 3 has a main counter transmission case 6 in which a main counter shaft 5 is mounted and a threshing counter transmission in which a threshing counter shaft 8 of a threshing device 7 is mounted below and below the support of the mowing frame 2. Since the case 9 is supported, the mowing support bracket 3 is reinforced by the counter transmission cases 6 and 9, and the support of the mowing frame 2 and the transmission of each part are stabilized even in a light-weight configuration. Wrapping of straw waste around the main counter shaft 5 and the threshing counter shaft 8 can be reduced, the mowing support bracket 3 can be configured to be low and compact, and maintenance can be easily performed. .

The front and rear ends of the track frame 29 are connected to the ends of the crank arm 25 by arm pins 30, and the crank arm 25 around the arm axis 26. By vertically moving the track frame 29 vertically, the support height of the crawler traveling device 4 with respect to the vehicle body 1 can be changed. The crank arm 24 protrudes above the arm shaft 26, connects the front and rear arms 24 with each other with a rod 31, and moves back and forth by a hydraulically expandable and contractible rolling cylinder, thereby changing the height of the crawler traveling device 4 to each of the right and left. Can be done separately.

The reaping support bracket 3 is integrally formed on the front end of the chassis frame 20 on the side opposite to the control table 16 and behind the transmission case 21. This mowing support bracket 3 has a hollow tower configuration. For the main part, an angle material, a square tube material, a round tube material, or the like is used. An oil tank 32 for storing oil used for hydraulic drive, an engine, or the like is fitted and attached to the turret-shaped hollow interior of the mowing support bracket 3.
