に構成してあるコンバインに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a machine equipped with a threshing device, in which a reaping section is connected so as to be freely raised and lowered around the axis of an input shaft in a horizontal position, which has an input pulley at one end in the left and right direction. Specifically, in the combine harvester installed, the reaping section is moved forward and backward relative to the machine so that the cutting height in the horizontal direction of the reaping section can be maintained almost constant regardless of the left and right tilting of the machine. This invention relates to a combine harvester configured to be able to roll freely around its axis.

つた。 In this type of conventional combine harvester, as shown in FIG. 4, the rolling axis P of the reaping section B is located on the axis of the input shaft 27 and passes through the center of the machine width when viewed from the front. However, in this case, it is necessary to separately provide an intermediate transmission shaft 26 on the rolling axis in a front-rear posture that meshes and interlocks the input shaft 27 with the front inclined transmission shaft 25 on the reaping section B side. This not only complicates the transmission structure, but also requires a lot of effort to assemble.

成とするものである。 In order to achieve the above object, the combine harvester according to the present invention has the above-mentioned structure, and the input shaft is supported near the input pulley among a pair of bearings that rotatably support the input shaft at both left and right ends. The supporting bearing part at one end is configured to be able to roll freely around the front and rear axes intersecting the input shaft, and the bearing part at the other end is configured to be freely repositionable and fixed around the front and rear axes. This is a characteristic configuration.

伝動トラブルの発生も抑制される。 In other words, the bearing part that supports the input shaft near the input pulley on one end of the input shaft in a horizontal position with respect to the aircraft is configured to be able to roll freely around the longitudinal axis that intersects the input shaft. Since the bearing part on the other end side of the is configured so that its position can be changed and fixed around the front and rear axes, the axial center is concentric with the axial center position of the transmission shaft that branches power forward from the input shaft to the reaping part. To enable rolling of a reaping part without rolling the reaping part around it. Furthermore, since the rolling center of the reaping section is set at a position near the input pulley, the distance fluctuation between the input pulley and the driving section on the machine side is small, and the occurrence of transmission troubles due to the distance fluctuation is also suppressed.

易化を図れるに至つた。 Therefore, according to the present invention, due to the integral rolling of the input shaft and the reaping section, there is no need to provide a special intermediate transmission shaft in the transmission system from the input shaft to the reaping section as in the past, and the transmission structure is improved. We have achieved simplification and ease of assembly.
