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.

  Thus, the conventional configuration (hereinafter referred to as the first conventional configuration) using the Karatsu shaft as a main transmission shaft of the transmission path from the engine to the threshing device and the swinging selection mechanism and the reaping device from the engine, Grains harvested by the reaping device are also used in so-called ordinary combine harvesters that are threshed in the state where the whole cereals harvested by the reaping device are put into the handling chamber of the threshing device (see Patent Document 1 below). It is also used in a so-called self-removing combine in which the culm is transported by the feed chain device and only the tip side of the harvested cereal culm is rushed into the handling room of the threshing device (the following patent document) 2).

  The first 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. 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 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.

  In addition, since the tang shaft is positioned on the upstream side in the transmission direction with respect to all of the handling cylinder, the swing sorting mechanism, and the cutting device, the handling cylinder, the sorting mechanism, and the cutting device are driven. In some cases, 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 of the reaping device. In the first conventional configuration, when the reaping device is driven in reverse. In addition, there is room for improvement in terms of reducing fuel consumption because the Karatsu shaft must be driven to rotate.

  In addition, an engine placed on the front side of the traveling machine body and 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 liftable connection to the front of the traveling machine body In the combine provided with the reaping device, the machine width direction one side and the other side extend from the threshing device outward in the body width direction in the state where the one side and the other side extend from the threshing device along the body width direction. Providing a countershaft, transmitting rotational power from the engine to one side of the fuselage shaft in the body width direction, transmitting rotational power from one side of the fuselage shaft in the body width direction of the countershaft to the one side of the countershaft in the body width direction; A configuration for transmitting rotational power from the other side of the counter shaft in the body width direction to the handling cylinder, the sorting mechanism, and the reaping device (hereinafter referred to as a second conventional configuration) has also been proposed (see Patent Document 3 below).

  In the second conventional configuration, it is necessary to secure an installation space for the counter shaft that is longer than the length in the machine width direction of the threshing device on the front side of the threshing device, which causes an increase in the size of the transmission structure. is there.

  In addition, the entire long counter shaft must be formed to have a strength that can withstand the combined force of the power that drives the barrel of the threshing device, the power that drives the swing sorting mechanism, and the power that drives the reaping device. In addition, there is a problem that the cost increases.

  Further, since the driving force of the handling cylinder, the swing sorting mechanism and the reaping device is taken out from one side in the body width direction of the Karatsu shaft, the handling cylinder, the same as the first conventional configuration, When driving the swing sorting mechanism and the mowing device, the tang shaft must be driven.

  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 rotational power for driving the handling cylinder 220 is the first output shaft 27a of the engine 25 → the first side of the first countershaft 610 → the handling cylinder input shaft 510. → Transmitted via a transmission path formed by the barrel cylinder 210.

  On the other hand, the rotational power for driving the reaping device 100, the swing sorting mechanism 260, and the sorting wind supply mechanism 280 is from the first output shaft 27a of the engine 25 to the first side of the first counter shaft 610. → The second side of the first countershaft 610 → the second countershaft 620 → transmitted via a transmission path formed by the reaping device 100, the swing sorting mechanism 260 and the sorting wind supply mechanism 280.

There is no long shaft that penetrates the threshing device 200 in the machine width direction.

  Therefore, compared to the conventional configuration in which the long shaft that penetrates the threshing device in the machine width direction is a common transmission path from the engine to the threshing device and the reaping device, the transmission load is concentrated on the long shaft. Power transmission to the threshing device and the reaping device can be effectively performed while effectively preventing.

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 drives the power for driving the handling cylinder, the power for driving the sorting mechanism including the rod shaft and the swing sorting mechanism, and the cutting device. It is necessary to have a strength that can withstand the resultant force of the power, and further, it is necessary to increase the strength so that the portions that support both ends of the tang shaft also can withstand the transmission load applied to the tang shaft, resulting in an increase in cost. Invite.

In the common transmission path that transmits the resultant force of the driving power, there is no long shaft that penetrates the handling chamber 201 such as the Karatsu shaft 281 in the machine body width direction.

  Therefore, while effectively preventing transmission load from being concentrated on the long shaft having a length corresponding to the length of the threshing device 200 in the body width direction, the handling cylinder 220, the reaping device 100, and the sorting mechanism 250. Rotational power transmission from the engine 25 can be realized.

  In the present embodiment, as described above, the rotational power to be transmitted to the swing sorting mechanism 260 is directly extracted from the second counter shaft 620, but instead, the rotational power is It is also possible to deform so as to be taken out from the hot shaft 281.

Rotational power for driving 100 is extracted.

  Specifically, as shown in FIG. 7, rotational power is transmitted from the first output shaft 27 a of the engine 25 to the first counter shaft 710 via the first work system endless body transmission mechanism 410.

  The rotational power transmitted to the first counter shaft 710 is transmitted to the first side of the second counter shaft 720 via a tenth work system endless transmission mechanism 730 such as a pulley transmission mechanism, and the first counter shaft 710 transmits the rotational power. 2 The operation is transmitted from the first side of the counter shaft 720 to the barrel input shaft 510 through an eleventh work system endless body transmission mechanism 740 such as a pulley transmission mechanism.

The driven side rotating body 752 is supported, and the driving side rotating body 751 and the endless body 753 wound endlessly around the driven side rotating body 752 are provided.

  The twelfth working system endless body transmission mechanism 750 can be a continuously variable transmission mechanism using a split pulley, like the sixth working system endless body transmission mechanism 460 in the first embodiment.

  In the present embodiment configured as described above, the rotational power for driving the handling cylinder 220 is as follows: the first output shaft 27a of the engine 25 → the first counter shaft 710 → the second counter shaft 720. Transmission is performed via a transmission path formed by the first side → the handling cylinder input shaft 510 → the handling cylinder shaft 210.

  On the other hand, the rotational power for driving the harvesting device 100, the swing sorting mechanism 260, and the sorting wind supply mechanism 280 is the first output shaft 27a → the first counter shaft 710 → the second power of the engine 25. Transmission is performed via a transmission path formed by the first side of the countershaft 710 → the second side of the second countershaft 720 → the reaping device 100, the swing sorting mechanism 260, and the sorting wind supply mechanism 280.

There is no long shaft that penetrates the threshing device 200 in the machine width direction.

  Therefore, compared to the conventional configuration in which the long shaft that penetrates the threshing device in the machine width direction is a common transmission path from the engine to the threshing device and the reaping device, the transmission load is concentrated on the long shaft. Power transmission to the threshing device and the reaping device can be effectively performed while effectively preventing.

  As described above, the first rotary shaft (the first counter shaft 610 in the first embodiment, and the red shaft 700 in the second embodiment) is hollow with the second rotary shaft (the first embodiment) via the bearing member. In the case where the tang shaft 281 and the first counter shaft 710 in the second embodiment are extrapolated so as to be relatively rotatable, there is preferably a rotational speed difference between the first and second rotation shafts. A transmission mechanism can be formed to occur.

  According to such a configuration, the bearing member supports the second rotating shaft only in the circumferential direction specific region, effectively preventing a so-called “one-sided” state, and the bearing member extends over substantially the entire circumferential direction. The second rotating shaft can be evenly supported.
