In other words, although the stock-holding / conveying device and the auxiliary conveying device partially overlap in the front-rear direction, at the start end of the auxiliary-transporting device, only the receiving grain stem from the stock-holding / conveying device is engaged to carry out the locked conveyance. In order to pass the culm from the root carrier to the auxiliary transport device by clamping at the middle part, the transport surface at the start end of the auxiliary transport device is formed to have a gentle curved surface But the curved transfer surface at the start end of the auxiliary transfer device is close to the transfer surface of the stock transfer device due to the manufacturing or assembly error of the auxiliary transfer device or the pinch transfer device. Conventionally, the stock feeder is provided at the middle part of the auxiliary transport device in the front-rear direction, so that the stock feeder is used to prevent the locked transfer at the start end of the auxiliary transport device. Can not be Conveying path in a three-point clamping state by the auxiliary transport device as well as strains based pinching transport apparatus becomes long, culms there was a possibility that torn by the relative speed difference between the strains based on nip-conveyed apparatus and the auxiliary transport device. Needless to say, the stock-holding / conveying device and the auxiliary conveyance device are configured to be driven at the same speed, but both are driven at the same speed by the power transmission structure for the stock-holding / conveying device and the power transmission structure for the auxiliary conveyance device. It cannot be done.

で修正される。According to the first aspect of the present invention, there is provided a vertical transport device for transporting a harvested grain culm to a feed chain by an ear-locking transport device and a stock-holding transport device.
The stock-holding / conveying device is configured to be swingable up and down around a front fulcrum for adjusting the handling depth, and a harvested grain culm is provided between an end portion of the stock-holding / conveying device and a start end of a feed chain. An auxiliary transport device that acts on the middle part of the culm body direction to impart a backward transfer force is provided in a fixed position, and at the lower part of the auxiliary transport device, abuts on the base of the cereal culm and acts on the grain culm. In a combine grain dispensing device provided with a stock dispenser for guiding the stock dispenser to the upper surface of the feed chain starting end, the stock dispenser is divided into two in the front-rear direction, and the front dispenser is rearward. The rear dispensing tool is fixedly provided on the auxiliary transporting device in a state having a guide function to the dispensing device, and the rear dispensing device is attached to the auxiliary transporting device in a cantilevered support state toward the feed chain side and capable of adjusting the posture. [Operation] According to this configuration, the stock dispenser provided at the lower portion of the auxiliary transport device is moved to the start end of the feed chain due to an assembly error of the transport system including the head, stock source, and auxiliary transport device and the threshing system. When the position is shifted back and forth and up and down,
As shown in FIGS. 3 and 4, when the rear dispensing tool 17B is changed in angle about the horizontal axis X with respect to the holder 19, the displacement of the dispensing surface in the vertical direction is corrected, and the holder 19 is moved to the auxiliary transport device. When the angle is changed around the vertical axis Y with respect to the fixing portion 11 of No. 5, the dispensing action position is corrected in the front-rear direction.

始端部に円滑に載り上がらせることができる。When the stock-holding / conveying device 3B is raised around the front fulcrum to adjust the handling depth for short culm, the rear dispensing tool 17B is moved to the horizontal axis X with respect to the holder 19. When the angle is changed upward, the stem of the short culm can be pushed up by the rear dispensing tool 17B and positioned above the start end of the feed chain 6, so that the stem is dragged by the start end of the feed chain. It is possible to avoid the stock source preceding transport state caused. In addition, in order to adjust the handling depth for long culm, the stock-holding and conveying device 3B
Is lowered around the front fulcrum, the rear dispensing tool 17
When the angle of B is changed downward about the horizontal axis X with respect to the holder 19 and the angle of the holder 19 is changed about the vertical axis Y, the action position of the rear dispensing tool 17B is positioned on the stock end side. This makes it possible to suppress the root portion of the grain culm from being bent by its own weight, and to smoothly raise the root portion of the long culm on the starting end of the feed chain.

Even when assembled in the state, that is, even when the transport path in the three-point support state by the tip-locking transporting device 3A, the auxiliary transporting device 5, and the stock-holding and transporting device 3B is formed long, the stock-out dispensing tool 17 can be used. Since the front dispenser 17A having the function of guiding to the rear dispenser 17B is provided at the start end of the auxiliary transport device 5 at the front end of the auxiliary transport device 5, the front dispenser 17A allows the front dispenser 17A to be used at the start end of the auxiliary transport device 5. Locked conveyance is prevented, and the transported culm is guided to the rear dispensing tool 17B while being guided by the front dispensing tool 17A.
Further, since the stock payout device is provided from the start end to the end portion of the auxiliary transport device and is divided into two parts in the front and rear, for example, as in the case of being constituted by one stock payout device, By adjusting the position of the end portion of the original dispensing tool back and forth, the position of the start end portion can be prevented from being displaced. [Effect] According to the invention according to claim 1, assembling errors of the transport system and the threshing system, and satisfactorily guiding the root portion of the grain culm to the upper surface of the starting end of the feed chain regardless of the length of the grain culm. And the culm can be transported favorably.

いる。)[Another Embodiment] As shown in FIG. 6, the starting end of the feed chain 6 may be configured to be vertically adjustable. In such a case, the volume of the transported cereal stem is large,
When the stock dispensing surface of the rear dispensing tool 17B is set at the lower position, the conveying surface at the start end of the feed chain 6 is set at the lower position, so that the transfer of the conveying grain can be smoothly performed. More specifically, the guide rail 25 of the feed chain 6 is divided into two front and rear parts, and the front guide rail 2
A passive sprocket 26 at the tip of the feed chain is mounted on 5A, and the front guide rail 25A is rotatably mounted on the rear guide rail 25B around the horizontal axis P1, and the front guide rail 25A is mounted on the rear guide rail 25B with a through bolt. It is fixed via 27. Two bolt insertion holes 27a are provided in the front guide rail 25A, and the upper surface of the tip of the feed chain 6 can be selectively changed vertically by selectively switching the connection holes 27a. . A tension arm 29 of a tension pulley 28 is rotatably mounted concentrically with the rotation axis of the front guide rail 25A.
A tension spring 30 is provided across the other end of the front guide rail 25A and the tension force of the tension pulley 28 is automatically adjusted with the upward movement of the front guide rail 25A. I have. The overlapping portion of the front guide rail 25A and the rear guide rail 25B is formed in an arc surface centered on the horizontal axis P1. (Note that components having the same functions as those of the above-described embodiment are denoted by the same reference numerals and symbols as those of the embodiment.)
