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 reaping device, the 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 handling cylinder of the threshing device, selection from the other side in the body width direction of the red pepper shaft It has been proposed to transmit rotational power to the mechanism and the reaping device.

  Thus, the conventional configuration using the Karatsu shaft as the main transmission shaft of the handling cylinder and sorting mechanism of the threshing device and the transmission path from the engine to the reaping device is the whole of the culm harvested by the reaping device. Is also used in a so-called ordinary combine that is threshed in a state where it is put into the handling room of the threshing device (see Patent Document 1 below), while the cereal harvested by the reaping device is conveyed by the feed chain device, It is also used in a so-called self-decomposing combine that is threshed with only the tip side of the harvested cereal buds entering 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 sorting mechanism of the threshing device and the reaping device, and the tang shaft in the threshing device. On the other hand, it has the following improvements.

  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 combined force of the power for driving the barrel, the power for driving the cutting device and the power for driving Karatsu, and further supports both ends of the Karatsu shaft. The portion to be made must also be strong enough to withstand the load applied to the Karatsu shaft, resulting in an increase in cost.

  According to the combine 1 which concerns on this Embodiment provided with such a structure, the following effect can be acquired.

  That is, in the present embodiment, the first output shaft 27a, the first working system endless body transmission mechanism 410, the pipe shaft 500, the second shaft are connected to the handling shaft 210 that supports the handling drum 220. Rotational power is transmitted through the work system transmission mechanism 420, the barrel input shaft 510, and the bevel gear mechanism 530.

  And, to the selection mechanism 250 of the reaping device 100 and the threshing device 200, although the transmission path from the first output shaft 27a to the handling cylinder input shaft 510 is common to the handling cylinder shaft 210, the handling cylinder Rotational power is transmitted from the input shaft 510 via the work system transmission mechanism 540.

  Here, the threshing device is included in a common transmission path of rotational power for driving the reaping device 100 and the threshing device 200 (that is, the transmission path from the first output shaft 27a to the barrel input shaft 510). There is no long shaft that penetrates 200 in the body width direction.

  Therefore, compared with the conventional configuration in which the rotational power is transmitted from the engine to the threshing device and the reaping device through the long shaft that penetrates the threshing device in the body width direction, the transmission load is concentrated on the long shaft. It is possible to effectively transmit power to the threshing device and the reaping device while effectively preventing the threshing.

  That is, an engine placed on the front side of the traveling machine body and one side in the machine body width direction, a threshing device placed on the other side in the machine body width direction of the traveling machine body, and a reaping device connected to the front of the traveling machine body In the combine equipped, the rotational power from the engine is inputted to one side (inner end side) of the tang shaft in the threshing apparatus, and the threshing is performed from the other side (outer end side) in the body width direction of the tang shaft. The structure (henceforth a conventional structure) which transmits rotational power to the handling cylinder and sorting mechanism of an apparatus, and the said cutting device is proposed.

  As the transmission shaft for transmitting the rotational power from the engine from the one side in the body width direction of the threshing device (substantially the center in the body width direction of the traveling aircraft body) to the other side in the body width direction of the threshing device. Although it also serves as the Karatsu shaft, it has the following disadvantages.

In other words, the tang shaft has a length penetrating the handling chamber in the machine width direction below the handling chamber of the threshing apparatus.
Therefore, in the conventional configuration, the entire long rod shaft can withstand the resultant force of the power for driving the handling cylinder, the power for driving the sorting mechanism including the rod shaft, and the power for driving the reaping device. It is necessary to have strength, and it is also necessary to increase the strength so that the portions supporting both ends of the rod shaft can withstand the transmission load applied to the rod shaft, resulting in an increase in cost.

  On the other hand, in the present embodiment, as described above, the driving force for driving the barrel 220, the driving force for driving the sorting mechanism 250 including the rod shaft 281 and the driving force for driving the reaping device 100 are transmitted. In the common transmission path, there is no long shaft that penetrates the handling chamber 201 such as the tang shaft 281 in the machine body width direction.

  Therefore, while effectively preventing concentration of transmission load on the long shaft having a length corresponding to the machine width direction length of the threshing device 200, the handling barrel 220, the reaping device 100, and the tang shaft 281 are arranged. Transmission of rotational power from the engine 25 to the sorting mechanism 250 can be realized.

  Further, in the present embodiment, as shown in FIG. 5, the transmission input shaft 32 operatively connected to the first output shaft 27a via the traveling system endless body transmission mechanism 400 and the first working system endless The transmission 30 is arranged so that the pipe shaft 500 operatively connected to the first output shaft 27a via the body transmission mechanism 410 is opposed to the first output shaft 27a.

  That is, the transmission 30 is arranged so that the transmission input shaft 32 is positioned approximately opposite to the pipe shaft 500 that is rotatably inserted relative to the flange shaft 281 with respect to the first output shaft 27a. ing.

  According to such a configuration, the force applied to the first output shaft 27a by the traveling system endless body transmission mechanism 400 and the force applied to the first output shaft 27a by the first work system endless body transmission mechanism 410 are offset. be able to. Accordingly, it is possible to take out the traveling system rotational power and the working system rotational power from the first output shaft 27a while effectively reducing the load on the first output shaft.
