Description

  The present invention relates to a combine.

  A front part of the traveling machine body and an engine placed on one side in the machine body width direction, a threshing device placed on the other side in the machine body width direction from the engine of the traveling machine body, and a forward and backward connection to the traveling machine body are connected. In a combine provided with a mowing device, rotational power from the engine is input to one side in the body width direction of the red pepper shaft in the threshing device, and the barrel and the swing of the threshing device are moved from the other side in the body width direction of the red pepper shaft. It has been proposed to transmit rotational power to the dynamic sorting mechanism and the reaping device.

  As described above, the conventional configuration using the tang shaft as the main transmission shaft of the transmission cylinder to the threshing device and the swinging selection mechanism and the reaping device from the engine is the cereal harvested by the reaping device. It is also used in a so-called ordinary combine that is threshed in a state where the whole is put into the handling chamber of the threshing device (see Patent Document 1 below), and the cereals harvested by the reaping device are being conveyed by the feed chain device. Moreover, it is utilized also in what is called a self-detaching combine in which the threshing process is performed in a state where only the tip side of the harvested cereal cocoon enters the handling chamber of the threshing apparatus (see Patent Document 2 below).

  The conventional configuration is useful in that it also serves as the main transmission shaft for transmitting power from the engine to the barrel and swinging selection mechanism of the threshing device and to the reaping device, and the tang shaft in the threshing device. However, it has the following improvements.

  That is, in the conventional configuration, the rotational power from the engine is transmitted to the inner end portion in the body width direction of the tang shaft, and the handling cylinder transmission along the body width direction from the outer end portion in the body width direction of the tang shaft. Rotational power is transmitted to the shaft and the swing sorting drive shaft, and the rotational power is transmitted from the handling cylinder transmission shaft to the handling cylinder and the cutting device.

  In this conventional configuration, since the Karatsu shaft acts as a common transmission shaft to the barrel and swinging selection mechanism of the threshing device and the reaping device, only the rotation speed of the Karatsu shaft is changed independently. There is a problem that can not be.

In addition, when driving the handling cylinder, the sorting mechanism, and the reaping device, the tang shaft must be driven.
That is, for example, there is a case where the reaping device is driven in reverse to take out the harvested cereal rice cake packed in the feeder house or the like of the reaping device, but in the conventional configuration, when the reaping device is driven in reverse. The tang shaft must be driven to rotate, and there is room for improvement in terms of reducing fuel consumption.

Further, the conventional configuration has a problem that a large load is applied to the long tang shaft.
That is, the tang shaft has a length penetrating the handling chamber in the machine width direction below the handling room of the threshing device, and in the conventional configuration, the long axis in the machine width direction. The whole Karatsu shaft must be formed to have a strength that can withstand the resultant force of the power for driving the handling cylinder, the power for driving the swing sorting mechanism, and the power for driving the reaping device. The portions that support both ends of the steel must also be strong enough to withstand the load applied to the tang shaft, resulting in an increase in cost.
