Description

[Detailed explanation of the idea] Industrial applications This invention relates to a harvester.

Conventional technology and problems to be solved by the invention Harvesters that move the machine body to thresh grain culms at appropriate positions generally have a threshing device in the upper front part of the running vehicle body, and a prime mover in the rear part. Harvester work is carried out by transmitting power from this prime mover to each part, but when performing maintenance inspections on the prime mover or its surroundings during or after work, the threshing device gets in the way. Even if the threshing device is rotated forward to avoid the threshing device, a cradle or the like is required to support the threshing device, and the rotating posture is unstable, making maintenance and inspection difficult.

Means for Solving the Problems This invention consists of a traveling vehicle body 2 on which a prime mover 1 is mounted and which can be maneuvered while running and driving, and this traveling vehicle body 2.
The motive power from the prime mover 1 on the traveling vehicle body 2 to the input shaft 3 of the threshing device 5 is connected to the threshing device 5, which is mounted so as to be rotatable back and forth with a support shaft 4 at a position spaced apart from the input shaft 3. A harvester comprising a belt 6 that transmits the rotation of the threshing device 5, and a locking portion 7 that locks the rotation of the threshing device 5 around the support shaft 4 in a predetermined rotational posture by the belt 6 in a non-transmission state. composition.

Effect of the invention While the traveling vehicle body 2 is driven by the drive of the prime mover 1, power is transmitted from the prime mover 1 to the input shaft 3 via the belt 6 to drive and rotate the threshing device 5 to perform harvester work. During this work or after the work is completed, the threshing device 5 is
When avoiding the surrounding area, for example, when the locking part 7 is provided on the traveling vehicle body 2 side, only one end of the belt 6 wrapped around the prime mover 2 is removed, and the rotation center is set around the spindle 4 in a non-transmission state. When the threshing device 5 is rotated forward with respect to the traveling vehicle body 2, the belt 6 also moves with this rotation, and one end of the belt 6 is locked to the locking portion 7, and The center of gravity of the threshing device 5 is locked in a predetermined rotational posture beyond the fulcrum. Conversely, if the threshing device 5 is to be returned to its working state, the procedure may be reversed.

Effect of the invention In this way, only one end side of the belt 6 that transmits power from the prime mover 1 mounted on the traveling vehicle body 2 to the input shaft 3 of the threshing device 5 is removed, and the support shaft 4 of the threshing device 5 is removed.
When the threshing device 5 is rotated forward with respect to the traveling vehicle body 2 with the rotation center at The threshing device 5 can be easily locked in a predetermined rotational posture, and the area around the prime mover 1 is left wide open, making it easy to inspect and maintain the prime mover 1 and its surroundings.
