Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-row cutting combine in which cut culms are transported in a Y-shape in plan view and supplied to a threshing unit for threshing. The present invention relates to a harvested grain culm transport device. 2. Description of the Related Art Conventionally, a multi-row cutting combine, in which a harvesting culm is fed to a threshing unit by a transport mechanism for transporting the harvested culm in a Y-shape and subjected to threshing processing, is composed of an upper and lower section having a fulcrum at the end of the transport mechanism. The handling depth is adjusted by movement, but this handling depth adjustment lacks the smooth transfer of the transfer action from good to poor ones in the transport mechanism. Japanese Patent Laid-Open No. 58-13
As disclosed in Japanese Patent No. 4907 and Japanese Utility Model Application Laid-Open No. 63-53220, even if the transport mechanism is further provided with a chain for engaging the tip of the head to adjust the handling depth, the inheriting action is smooth and the culm is prevented from being disturbed. I am trying to do it. [0003] However, even if it is possible to prevent the grain culm from being disturbed while the grain culm is being conveyed by the conveying mechanism by providing the chain for feeding the spikes as described above, the mechanism of the conveying mechanism can be prevented. Since the whole becomes complicated and the number of parts increases, the present invention does not increase the number of parts as much as possible, and the culm during transportation is adjusted even if the handling depth is adjusted while simplifying the configuration. It was invented for the purpose of smoothly transporting the threshing unit without disturbance. [0004] In order to achieve the object described in the preceding paragraph, the present invention relates to a method for feeding a harvested grain culm to a threshing unit by a transport mechanism for transporting the harvested culm in a Y-shape in plan view. In the transport mechanism, the right and left roots of the cereal culm that the right and left roots of the cereal lumps join together by the root transport chain are inherited and transported. An extending right spike transfer chain and a left spike transfer chain connected by a transmission case detoured downward from the starting end of the vertical transfer chain are provided above the left stock root transfer chain. The end of the transport mechanism of the right and left spike chains is configured to be able to move up and down integrally with the fulcrum as a fulcrum to adjust the handling depth. [0005] As a result, the harvested culm is passed from the good to the poor by the transport mechanism, supplied to the threshing unit, and subjected to threshing. That is, the roots of the grain stems that are joined by the right and left roots are conveyed to the vertical conveying chain, and the left front is transferred from the left by the left front feeding chain. The spikes sent by the spike chain are merged with the spikes at the middle part, the right spikes are transferred at the middle part of the tine, and supplied to the threshing unit in cooperation with the vertical transport chain. It is. When the culm of the harvested grain culm is a long culm, the vertical conveying chain is moved upward with the end of the conveying mechanism as a fulcrum, so that the culm portion with the tip of the horn is pinched and shallowly handled. In the case of short culm, the vertical transport chain is moved down to hold the base of the stock and adjusted to the state of deep handling, but the vertical transport chain is adjusted to this shallow or deep handling state Then
At the same time, the left and right spike feeding chain can move up and down with the relative position of the vertical transport chain and the relative position of the left and right spike feeding chain unchanged, without disturbing the culm. It is inherited from the thing of the walnut to the thing of the poor walnut, and the threshing unit is conveyed.

The transmission case (27) which is detoured toward the left side integrally moves the chain with the left spike (6) up and down. Accordingly, the adjustment of the handling depth is performed by the wiper
In this case, when the culm of the harvested grain culm is a long culm, the starting end of the vertical transport chain (4) is moved up with the output shaft (22) as a fulcrum. When the spikes of the grain culm conveyed by the right and left stems are conveyed by the chain (2) and (3), the culm of the culm is clamped and adjusted to a shallow condition. The chain (5) and the chain with the left ear tip (6) move upward together with this, and become the state shown by the phantom line in FIG. 1. In the case of a short culm, the chain (4) with the vertical conveyance is reversed. When it is moved down to hold the base of the stock and adjusted to the deep handling state, the right spike transfer chain (5) and the left spike transfer chain (6) move down at the same time. Chain for sending the left and right spikes in adjusting the depth (6)
(5) moves up or down with the relative position with the vertical transport chain (4) and the mutual relative position of the left and right spike chains (6) and (5) unchanged, so that the culm is disturbed. The threshing section is conveyed without any effort. In FIG. 1, the right spike transfer chain (5) and the left spike transfer chain (6) are illustrated as having a difference in height. As shown, they are of the same height, and when viewed from the side, they are superposed and difficult to understand. As described above, the harvested grain culm transport apparatus according to the present invention supplies the harvested grain culm to the threshing unit by the transport mechanism (1) for transporting the harvested grain culm in a Y-shape in plan view.
Right and left stock transfer chain (2) in the transfer mechanism (1)
A vertical transport chain (4) that inherits and transports the root of the grain stem that joins by (3), and extends from above the right root to the vertical transport chain (4). The right spike forward chain (5) and the transmission case (2) diverted downward from the starting end of the vertical transport chain (4).
7), the left spike chain and the chain (6) are provided above the left strain root chain (2).
The end of the transport mechanism (1) of the right ear tip chain transfer chain (6) (5) is configured to be able to move up and down integrally with the fulcrum as a fulcrum to adjust the handling depth. Therefore, when the culm of the harvested grain culm is a long culm, the vertical transport chain (4) is moved upward with the end of the transport mechanism (1) as a fulcrum to pinch the culm part where the ears are close. In the case of a short culm, the vertical transport chain (4) is moved down to clamp the base of the stock and adjust to the deep-handed state. When the vertical transport chain (4) is adjusted to the state, the right and left spike chain transfer chains (6) and (5) are located at the relation position with the vertical transport chain (4) and the left and right spike chain (6). ) Since the relative position of (5) moves up or down while the relative position remains unchanged, the culm is not disturbed, and Since it is smoothly inherited and the threshing section is conveyed smoothly, it is not necessary to attach a chain for transferring ears in addition to the conveying mechanism (1) as in the conventional one. Keep the configuration simple without increasing the size. In addition, the left ear tip transfer chain (6) has a transmission case (2) which is detoured downward from the start end of the vertical transport chain (4).
Since the connection is carried out according to 7), a support member for preventing the tip of the grain culm to be conveyed is not required, the machine body can be kept low, and the threshing unit can be smoothly conveyed.
