Description

[Detailed description of the invention] The present invention allows the harvested stem culms introduced from a plurality of paths formed by a plurality of pulling devices to be transferred from both the left and right sides of the machine by the cooperation of the first and second conveyance devices. A merging conveyance device is provided that conveys and merges toward the center and conveys the merged stem culm toward one side at the rear of the machine, and conveys the merged stalk culm from the merge conveyor device to a post-processing device. This invention relates to a reaping harvester equipped with a vertical conveyance device.

In the above-mentioned reaping and harvesting machine, in order to drive and support the first conveying device located on the side of the vertical conveying device in the left-right direction of the machine, the driving wheel body of the first conveying device is conventionally attached to the hoisting drive shaft for the hoisting device. is spline-fitted, and the cover of the first conveying device is detachably attached to the case in which the lifting drive shaft is housed. However, in the initial stage, when assembling the lifting drive shaft, it must be assembled with the first conveyor device attached, which makes it difficult to assemble, and it is also difficult to remove only the first conveyor device. Repairs, such as removing straw debris stuck inside, had to be carried out while the shaft was still attached to the lifting drive shaft, making the repair troublesome and time-consuming.

In view of the above points, it is an object of the present invention to provide a first conveyance device that can be easily assembled and repaired without expanding the installation space.

Next, embodiments of the present invention will be described in detail based on illustrative drawings.

The upper part of the endless rotation band 11 is covered by a cover 13 having a simple structure.

The lifting drive shaft 14 for the lifting device 1 is inserted into the bent portion A of the first conveying device 3a and is close to the outer peripheral edge of the cover 13.
is set upright, and its lifting drive shaft 14 and the drive shaft 15 of the first conveyance device 3a are interlocked and connected via a bevel gear mechanism 16 that employs a reduction configuration, which is an example of a gear type transmission mechanism, and a bevel gear mechanism. Raise the gear case 17 containing the gear case 16 inside the drive shaft 14.
At the same time, the cover 13 is detachably attached to the gear case 17, and the first conveying device 3a is raised by the drive shaft 14.
is supported.

The driven shaft ₁ is moved upward from the wheel 9 that bends the endless rotating belt 11 from the horizontal conveyance device r1 to the combined conveyance path _r2 .
9 is provided in a protruding manner, and locking and conveying devices 20, 20 are provided on the driven shaft 19 at intervals in the axial direction to act on the middle of the grain culm in the direction of the culm and on the ear side.

At or near the end of the combined conveyance path _r2 , the upper surface of the cover 13 is bent downward to be positioned lower than other parts, and the vertical conveyance device 5 is used to adjust the handling depth. When swinging around the horizontal axis P on the conveyance starting end side, the pinning rail 21 is inserted into the bent part B, and the tip of the pinning rail 21 is brought as close to the cover 13 as possible over the entire handling depth adjustment range, and the grain is The structure is designed to allow smooth culm delivery.

In summary, in the above-mentioned reaping/harvesting machine, the first conveying device 3a located on the vertical conveying device 5 side in the left-right direction of the machine is constituted by a horizontal conveying path _r1 and a converging conveying path _r2. One endless rotating band 11 that rotates along the non-conveying action path _r3 is bent so that it enters inside the fuselage, and when it enters the bent part A, and the above-mentioned A lifting drive shaft 14 for the lifting device 11 is set upright while passing beside the cover 13 of the endless rotation band 11, and the lifting drive shaft 14 and the drive shaft 15 of the endless rotation band 11 are connected to each other by gears. The first conveying device 3 is interlocked and connected via a transmission mechanism 16.
Case 1 in which a is raised and the drive shaft 14 is installed inside.
8 and is detachably supported via a case 17 in which the gear type transmission mechanism 16 is housed.

That is, since the path of the endless rotating band 11 constituting the first conveying device 3a is bent, and the drive shaft 14 is provided by pulling it up while entering the bent part A,
In order to remove the lifting drive shaft 14 from the rotation path of the endless rotation band 11, the lifting drive shaft 14 is moved to the first position.
By extending the transfer device 3a laterally outward to expand the installation space, it is possible to avoid the problem of damage, and moreover, the lifting drive shaft 14 and the drive shaft 1 of the endless rotation band 11 can be
5 are interlocked and connected via a gear type transmission mechanism 16, and the first conveyance device 3a is detachably supported by the case 18 of the drive shaft 14 by lifting it up by attaching and detaching the cases 17 and 18. The first conveying device 3a can be attached and detached after the shaft 14 is assembled, making it easy to assemble the lifting drive shaft 14, and making repairs such as removing straw waste easily by removing only the first conveying device 3a. I was able to do it.
