Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a culm transfer and conveyance device in a reaping and threshing machine.

In conventional devices of this type, the terminal end of the reaping transport device that transports the harvested husk and the starting end of the threshing machine's pinning transport device are in a vertical relationship, and in order to vertically adjust the reaping position, When the reaping conveyance frame is moved up and down, the terminal end of the reaping conveyance device that moves up and down along with it moves closer to or away from the start end of the husk culm conveyance device each time, resulting in a large deviation in the vertical position. It had become.

In other words, if the vertical positions of the two are far apart, the terminal end of the reaping conveyance device will be located above the starting end of the culm transfer conveyance device, and the vertical height will be higher, and the inherited culm will fall due to this drop. There was a drawback that the posture was disordered and the inheritance was not carried out smoothly.

In addition, if the relative positions of the two are too close, that is, if the reaping position is set high, the terminal end of the reaping transport device may collide with the starting end of the threshing rod of the threshing machine, resulting in a defect. there were.

In contrast, the present invention has a structure in which the starting end of the threshing rod of the threshing machine can be moved up and down in conjunction with the vertical movement adjustment of the reaping transport frame, and the position relative to the terminal end of the reaping transport device is adjusted. Regardless of whether the reaping conveyance frame is adjusted up or down, the reaping culm is always maintained properly to ensure smooth and reliable succession of reaped husk culms.

Hereinafter, one embodiment of the present invention will be specifically described based on the drawings.

First, we will discuss its configuration.

The reaping transport frame 1 includes a reaping device 2 provided at a low front position,
A reaping and conveying device 4 whose starting end is positioned on the reaping device 2 and whose terminal end is viewed from a culm trapping and conveying device 3 to be described later is constituted as a framework, and is installed on the front part of the chassis 5 so as to be able to adjust its vertical movement. ing.

The threshing machine 6 is located at the rear of the reaping conveyance frame 1, and the husk culm conveying device 3 is provided with a threshing chain 7 on the upper side and a threshing rod 8 on the lower side along the handling opening. Equipped with

The starting end portion 8a of the pinning rod 8 is provided with one end pivotally connected to the pinning rod 8 and the other end being pivotally connected to the connecting rod 9, and the end of the connecting rod 9 is connected to the mounting rod 10. It is attached to the vicinity of the rotational fulcrum of the reaping conveyance frame 1 via the reaping and conveying frame 1.

In addition, the connecting rod 9 is provided on the mounting rod 10 so as to be freely slidable in the axial direction.
The spring 11 is configured to tension the starting end portion 8a of the clamping rod upward.

12 indicates a retaining pin.

Reference numeral 13 indicates a cutting body, 14 indicates a culm pulling device, 15 indicates a narrow guide, 16 indicates a crawler, 117 indicates a transfer guide rod, and b indicates a pivot point of the reaping conveyance frame 1.

Next, its effect will be explained.

First, when the work is carried out with the reaping transport frame 1 positioned at a low position as shown in FIG. The culm is transferred from the terminal end to the starting end of the culm gripping and conveying device 3.

The culm is then subjected to threshing processing by the threshing machine 6.

During such work, the starting end portion 8a of the clamping rod maintains an appropriate distance from the terminal end portion of the reaping and conveying device 4, so that the extra husks can be reliably inherited.

Next, when the length of the culm in the field is long, the reaping conveyance frame 1 is rotated upward as shown in FIG. 4, and the reaping device 2 is adjusted to a high position to perform the work.

Then, as the reaping transport frame 1 rotates, the reaping transport device 4 approaches the gripping rod 8 side significantly. At the same time, it is rotated downward via the mounting rod 10 and the connecting rod 9, so that the distance from the terminal end of the reaping and conveying device 4 described above can be corrected to an appropriate state.

If the work is carried out in this manner, the husks cut by the reaping device 2 will be reliably supplied to the starting end of the culm gripping and conveying device 3 of the threshing machine 6 by the reaping and conveying device 4, and subjected to the threshing action. be.

The present invention provides a reaping conveyance frame which is constituted by a reaping conveyance device that inherits and supplies the reaped husk culm to the starting end of the husk gripping conveyance device of a threshing machine, and a reaping device installed at a low position in front of the reaping conveyance device. The shell is located on the front side of the threshing machine, and is provided so that the reaping position can be adjusted up and down using the rear frame portion on the side of the shell culm inheritance and conveyance device as a rotation fulcrum, and the shell is provided along the handling opening of the threshing machine. The culm clamping conveyance device is constituted by an upper clamping chain and a clamping rod provided along the lower side thereof, the starting end of which is close to the terminal end of the reaping conveyance device, and the reaping conveyance frame body When the is rotated up and down to adjust the reaping position up and down, the starting end of the gripping rod is positioned in an appropriate vertical relationship with the terminal end of the reaping and conveying device, which both move up and down, for culm inheritance. The culm transfer and conveyance device in the reaping and threshing machine is constructed in such a way that the starting end of the clamping rod is interlocked and connected to the reaping and conveying frame body in order to rotate in an interlocking manner up and down while maintaining the reaping position. When the reaping transport frame is rotated up and down, the starting end of the clamping rod moves vertically in sync with the rotation, and the end of the reaping transport device on the reaping transport frame side always maintains the proper vertical position for culm inheritance. As a result, it is possible to maintain the interval and prevent a large difference in the rise and fall between the two.
This feature prevents the receiving husk culm from being disturbed in the process of falling due to the difference in fall, and allows the receiving and conveying of the reaped husk culm to be carried out smoothly and reliably.

In particular, it is possible to prevent problems such as the terminal end of the reaping and conveying device colliding with the gripping rod when the reaping position is raised as in the conventional configuration described at the beginning.
