Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a combine for cutting and threshing of grain culms in a linked manner, and a supply length of the tips of the slaughter grain culms to be supplied to the handling room is set to a constant length. Depth adjustment device for keeping the height of the handle.

"Prior art" Conventionally, as shown in Japanese Utility Model Publication No. 60-36027, front and rear transport chains and front and rear transport tines are provided, and the chains and tines hold the stems and tips of the grain stems. There is a technique in which the rear conveyance chain feed start end is moved up and down by a handling depth adjusting motor while being conveyed, and the rear conveyance tines are interlocked and moved up and down by abutting from the lower side of the chain.

[Problems to be Solved by the Invention] In the above-mentioned conventional technology, a space is provided between the front transport tine feed start end and the rear transport tine feed end so that the rear transport tine does not interfere with the front transport tine when rotating. Therefore, there is a problem in that a dead space for tine transportation is formed, and problems such as spillage occur.

[Means for Solving the Problems] Therefore, the present invention is provided with front and rear transport chains and front and rear transport tines, and allows the chains and tines to grip and transport the stems and tips of the grain culms. In a combine handling depth adjusting device for moving a rear transport chain feed start end up and down by a handling depth adjusting motor and vertically moving the rear transport tines by abutting from the lower side of the chain, a front transport tine The rear transport tine feed start end extends forward of the feed end of the rear transport tine, the rear transport tine start end is wrapped above the front transport tine end, and the rear transport tine lower surface can be raised to the front transport tine upper surface side. It is characterized in that it is provided with a stopper for supporting.

[Operation] Therefore, by mounting the stopper on the upper surface side of the front transport tine feed terminal end or the lower surface of the rear transport tine feed start end, it is possible to easily prevent the formation of a dead space between the front and rear transport tine. Thus, the conventional problems such as the occurrence of culm spill can be easily eliminated, and the grain culm inheritance between the front and rear transport tines and the handling depth adjusting operation can be properly performed.

As is clear from the above, the right culm source transfer chain (26a) and the vertical transfer chain (30a) that are the front and rear transfer chains, and the right tip tip tine (27a) and the rear tip that are the front and rear transfer chains. The transfer tines (31a) are provided, and the chains (26a) (30a) and the tines (27a) (3) are provided.
1a) holds and conveys the roots and tips of grain culms, and the handling depth adjusting motor (53) moves the feed start end of the rear transport chain (30a) up and down to bring the chain (30a) into contact with the lower side. In the combine handling depth adjusting device that moves the rear transport tine (31a) up and down in conjunction with
The rear transport tine (31a) feed start end is extended in front of the feed end of the front transport tine (27a), and the rear transport tine (31a) start end is wrapped above the end of the front transport tine (27a). First rear support tine (27a) is supported on the upper surface of the rear transfer tine (31a) so that the lower surface of the rear transfer tine (31a) can be lifted.
A stopper (58) is provided.

In this embodiment, the cutting blade (2
Conveyance where the culm side and the tip side of the grain culms cut in 5) are the feed ends of the front left and right culm-holding conveying devices (28) (26) and the front left and right cusp locking conveying devices (29) (27) When reaching the merging portion of the route (33), it is inherited by the rear culm pinching / conveying device (30) and the rear cusp locking and conveying device (31), and the culm side of the cut grain culm is fed to the feed chain (5), and the cusp is further cut. The side is supplied to the handling room and threshing processing is performed.

Further, in order to keep the supply length of the tips of the cutting grain culms to be supplied to the handling room at a constant length, when the cutting grain culm is a short culm, the motor (53) is driven to the forward rotation side. While lowering the feed start end side of the culm pinching / conveying device (30) to the position indicated by the solid line in Fig. 1 centering on the vertical conveying output case (41), the motor (53) is used when the cut culm is a long culm. By driving to the reverse rotation side, the feeding start end side of the rear squeezing device (30) is raised to the imaginary line position in FIG. 1 about the vertical transport output case (41).
The position for holding the grain culm in the feed chain (5) is appropriately changed in accordance with the length of the grain culm. At this time, the first tipper stopper (58) of the rear tip locking device (31) is used during the short culm. Until it hits the front right tip locking transfer device (27), it interlocks with the rear tip pinching transfer device (30) via the second stopper (59),
The feeding start end side is lowered around the vertical conveyance output case (41), but when the first stopper (58) hits the front right tip locking conveyance device (27), the rotation of the rear tip pinching conveyance device (30) occurs. The movement is absorbed by the rear tip transport output case (43) and is supported at that height position, and thereafter only the feed start end side of the rear tip pinching transport device (30) descends around the vertical transport output case (41). While reaching the position shown by the solid line in FIG. 1, the rotation of the rear tip pinching and conveying device (30) causes the rear tip end clamping and conveying device (31) to rotate until the second stopper (59) contacts the rear tip end conveying device (31) during long culm. The feed start end side is absorbed by the output case (43) and abutted and supported on the feed end side of the front right tip end locking and conveying device (27) via the first stopper (58), but the second stopper (58). After hitting the rear tip locking and conveying device (31), the rear culm is passed through the second stopper (59). The starting end side of the rear-end tip locking transport device (31) is integrally lifted centering on the vertical transport output case (41) in conjunction with the sandwiching transport device (30), and these rear stencil sandwiching transport device (30) and the rear part Tip locking transfer device (31)
Each of the feeding start ends of the carriage reaches the phantom line position in FIG. 1, and together with the rear stem holding device (30), the front right tip locking transport device (2
The depth of the grain culm is adjusted by rotating the rear tip locking and conveying device (31) that has a tine (31a) locus where the front end wraps at the rear end of the tine (27a) locus in 7). is there.

[Advantages of the Invention] As is apparent from the above-described embodiments, the present invention is provided with front and rear transport chains (26a) (30a) and front and rear transport tines (27a) (31a). 26a) (30a)
And the tines (27a) (31a) are used to hold and convey the roots and tips of the grain culms, and the handling depth adjusting motor (53) vertically moves the feeding start end of the rear conveyance chain (30a) to move the chains (30a). In the depth-adjusting device of the combine, which moves the rear transport tine (31a) up and down by abutting from the lower side, in the rear transport tine (31a) feed forward of the feed end of the front transport tine (27a). The start end is extended and the start end of the rear transfer tine (31a) is wrapped above the end of the front transfer tine (27a) so that the front end of the front transfer tine (27a) is raised to the bottom of the rear transfer tine (31a). A stopper (58) that is freely supported is provided. By mounting the stopper on the upper side of the front transport tine feed terminal end or the lower side of the rear transport tine feed start end, a dead space is provided between the front and rear transport tines. It is possible to easily prevent the formation of soot, easily eliminate the conventional problems such as culling spillage, and to properly perform the operation of transferring the grain culm between the front and rear transport tines and adjusting the handling depth. Is something that can be done.
