Description

[Detailed Description of the Invention] The present invention relates to a continuous pinching and conveying device for a threshing machine, which is provided with an upper chain type waste straw pinching and sending device connected to the conveying end of an underchain type threshing section pinching and conveying device.

In this type of conventional continuous pinching and conveying device of a threshing machine, the receiver from the conveying end of the threshing section pinching and conveying device to the conveying start end of the straw removing straw holding and sending device is provided at both ends as a means to ensure the passing action. In the meantime, a rigid guide rod for baton touch was provided, but this would not only complicate the structure of the transfer section of the waste straw holder, but also make it difficult for the holder to transfer the waste straw while holding it between the straws and sending it out. There is no lifting function on the clamping and conveying surface of the device, and the distance between this guide rod and the clamping and conveying surface of the straw clamping and sending device is kept constant, so the volume of the straw is particularly small. When this happens, there is a problem in that the conveying posture of the waste straw is disturbed and the straw tends to fall off.

In view of the above-mentioned circumstances, the present invention provides a transfer function for the waste straw receiver from the threshing section holding and conveying device to the waste straw holding and sending device.
This can be carried out reliably and well at all times regardless of changes in the volume of the waste straw, and the structure for this can be easily constructed using the members originally attached to the threshing section holding and conveying device side. Have a purpose to be as calm as possible.

That is, the continuous clamping and conveying device for a threshing machine according to the present invention is officially registered, and is located at the end of the conveyance of the guide rail that guides the movement of the endless chain on the side of the threshing section clamping and conveying device, and at the The feature is that a guide rail portion of an appropriate length located opposite to the conveyance starting end of the clamping and feeding device is configured to be able to be elastically displaced downward, so that the threshing portion can be fed out from the threshing section clamping and conveying device. The waste straw, which tends to fall downward under its own weight, can be elastically pressed against the clamping and conveying action surface of the straw removal clamping and feeding device by the guide rail portion. Even when the transport volume of waste straw is small, the waste straw can be reliably received and transferred without any disturbance in the transport posture or dropping of waste straw. Therefore, continuous conveyance can be carried out smoothly without any clogging.

Furthermore, by using the guide rail originally attached to guide the movement of the endless chain on the side of the threshing section holding and conveying device, the end of the chain is connected to the end of the chain and the starting end of the chain of the straw removing straw holding and sending device. The above-mentioned effects can be achieved by a simple structural improvement in which the guide rail portion of an appropriate length is configured to be elastically displaceable downward.

Embodiments of the present invention will be described below based on the drawings.

(The drawing shows the rear part of the threshing machine mounted on a combine harvester.) In the figure, 1 is an underchain type threshing section clamping and transporting device that clamps and transports the harvested husks along the suction port of the threshing device 2 in an eJ posture. , an endless chain 3 with protrusions whose upper moving portion 3A serves as a clamping and conveying surface, and this chain 3.
A guide rail 4 that comes into contact with the back surface of the upper moving part 3A to guide the movement of the chain 3, a plurality of split clamping rails 5 provided opposite to the clamping and conveying working surface 3A, and
A spring 6 for biasing the divided clamping rails 5 toward the clamping and conveying working surface 3A of the chain 3 is also constructed.

The threshing section holding and conveying device 1 also pinches and conveys the waste straw sent out in a sideways posture 11 to the rear inside of the machine body, and transfers this to the rear of the threshing device 2. This is an upper chain type waste straw clamping/feeding device that supplies waste straw to the processing device 8, and this is a device that clamps the lower movable portion 9A, which is partially overlapped with the conveying end portion of the chain 3, and provides a conveying working surface. An endless chain 9 with protrusions, a clamping rail 10 opposite to the clamping and conveying surface 9A, and a spring 11 that biases the clamping rail 10 toward the clamping and conveying surface 9A of the chain 9.
・It is configured like this.

Then, at the conveyance end of the guide rail 4 of the threshing section clamping and conveying device 1, and at the end of the guide rail 4 of the threshing section clamping and conveying device 1,
A guide rail portion 4A of an appropriate length located opposite the conveyance start end of the is pivoted to the other guide rail portion 4B in the direction of the culm of the waste straw about axis 5 along axis a. A coil spring 12 is interposed between the guide rail portion 4A and a fixed portion on the side of the threshing device 2, which swings and biases the guide rail portion 4A upward. It is configured so that it can be elastically displaced downward according to the conveyance volume of the passing and discharging straw.
