DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical conveying device for feeding cereals to a threshing feed chain, which is provided so as to be swingable in the longitudinal direction of the conveying culms around a fulcrum on a rear end side for adjusting a depth. The present invention relates to a grain culm transport section of a self-removing type combiner having a stock delivery rod for delivery at the stock side between a vertical transport device and a threshing feed chain, and more particularly, to a mounting structure of the stock delivery rod.

[0002]

2. Description of the Related Art Conventionally, the front end side of a stock payout rod is fixed to a vertical conveying device in a cantilevered rearward direction, so that the stock payout rod moves up and down integrally with the vertical conveying device.

[0003]

However, when the vertical conveying device is swung downward in order to correspond to the short culm, the stock payout rod goes down from the starting end side of the threshing feed chain to move the short culm stock side. There was a possibility that the short culm could not be properly transferred from the vertical conveying device to the threshing feed chain and could fall, resulting in room for improvement in terms of culm conveying performance. An object of the present invention is to smoothly and reliably supply grain culms from a vertical transport device to a threshing feed chain regardless of the grain culm length.

[0004]

The feature of the present invention is that a vertical conveying device for feeding grain culms to a threshing feed chain is swung in the longitudinal direction of the grain culm around a fulcrum on the rear end side for adjusting the depth. In the self-removing type combine where a stock delivery bar is provided between the vertical conveyance device and the threshing feed chain, the front end side of the stock delivery bar is connected to the vertical conveyance device with a universal joint. Connect and after the stock payout rod
The end side is provided at the transport start end of the threshing feed chain.
That it is connected to a threshing device via a universal joint .

[0005]

[Function] In other words, the front end of the stock delivery rod is connected to the vertical conveying device and the rear end is connected to the threshing device near the conveying start end of the threshing feed chain by a universal joint. Even if the culm is swung in the longitudinal direction around the fulcrum around the rear end side for adjustment, the front end side of the stock dispensing rod can be maintained at a position where the culm can be received well from the vertical conveyance device, and The rear end of the dispensing rod can be maintained at a position where the culm can be passed to the threshing feed chain in a favorable manner, and the dispensing rod acts to supply the culm from the vertical transport device to the threshing feed chain regardless of the length of the culm. Can be realized smoothly and reliably.

[0006]

As a result, regardless of the length of the culm, the supply of cereal culm from the vertical conveying device to the threshing feed chain can be smoothly and reliably realized by the action of the stock dispensing rod. A self-contained combine can now be provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a cutting unit 2 is connected to a front part of a vehicle body traveling by a crawler type traveling device 1 by a hydraulic cylinder 3 swinging around a support shaft 4 so as to be vertically movable. A threshing device 7, a driving unit, a control unit, and the like are mounted on the vehicle body, and a planted grain culm raising device 5, a cutting blade 6, a feeder side clamping / conveying device 8a for sending the harvested grain culm to the threshing device 7, and a head side keeper. The cutting unit 2 is provided with a vertical conveying device 8 comprising a stopping conveying device 8b, etc., and a threshing feed chain 9 for receiving the culm from the cutting unit 2 in a sideways posture is provided on a side surface of the threshing device 7 to provide a self-removing combine. It is composed.

As shown in FIG. 2, a vertical conveying device 8 is mounted on the grain culm conveying path so as to be swingable in the longitudinal direction of the conveying culm around the lateral fulcrum P on the rear end side for adjusting the handling depth. The vertical conveying device 8 is automatically swung by an actuator 10 such as an electric motor so that the grain culm tip is located between the pair of culm length detection sensors Sa and Sb, and the threshing device is independent of the grain culm length. An automatic processing depth control device for maintaining the processing depth at 7 substantially constant is provided.

[0009] As shown in FIG.
a is composed of a chain 8aa with a conveying protrusion, a clamping rail 8ab and an extending rail 8ac which elastically move in opposition to the chain 8aa. Threshing feed chain 9
And is conveyed to the starting end of the transfer. And
This stock side holding and conveying device 8a and threshing feed chain 9
A stock delivery rod 11 for stock delivery is provided between
The front end side of the stock payout rod 11 is held at the stock side holding and conveying device 8a.
And a universal joint 12 such as a ball joint, and the rear end side of the stock payout rod 11 is connected to the threshing device 7 by a universal joint 13 near the conveying start end side of the threshing feed chain 9.

In order to form the universal joint 13 with respect to the rear end side of the stock payout rod 11, a bracket 14 is mounted on a rail frame (not shown) supporting the threshing feed chain 9 with the bracket 14 disposed inside the cover 15, and The rod 16 rotatably mounted on the rod 14 is prevented from coming off by a pin 17, and a support shaft 18 is attached to a protruding end of the rod 16 from the cover 15.
, The stock payout rod 11 is swingably connected. A plurality of pin holes for the pin 17 are juxtaposed in the longitudinal direction of the rod 16, and the rear end position of the stock dispensing rod 11 can be adjusted in the perspective direction with respect to the threshing feed chain 9 by selecting the pin hole for mounting the pin 17. It is composed.

That is, the front end side of the stock payout rod 11 is connected to the vertical conveying device 8 and the rear end side thereof is connected to the threshing section 7 near the conveying start end side of the threshing feed chain 9 by universal joints 12 and 13, respectively. Even if the device 8 is swung around the fulcrum P on the rear end side for the handling depth adjustment in the longitudinal direction of the conveying culm, the front end side of the stock dispensing rod 11 can receive the cereal stalk from the vertical conveying device 8 satisfactorily. And the rear end side of the stock dispensing rod 11 is maintained at a position where the grain culm can be satisfactorily passed to the threshing feed chain 9 regardless of the length of the grain culm. The construction is such that the supply of cereal stalks to 9 is smoothed by the action of the stock delivery rod 11.

[Other Embodiments] A universal joint 12 for connecting the front end of the stock payout rod 11 to the vertical conveying device 8 and a universal joint 13 for connecting the rear end of the stock payout rod 11 to the threshing device 7. The type can be appropriately selected from known ones, and the mounting positions of the universal joints 12 and 13 with respect to the vertical conveying device 8 and the threshing device 7 can be appropriately changed.

In the claims, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the configuration shown in the attached drawings.
