Description

[Detailed description of the invention] This invention is installed at a culm discharge position where the threshed culm of a mobile threshing machine is discharged as a long culm, and the culm is collected in a predetermined amount and discharged to the field. Relating to a dropper device.

Since the falling position of the culm discharged from the culm discharge part of the mobile threshing machine is approximately constant, a culm receiving member having a width that is approximately the same as the culm length of the culm is provided at this culm falling position. This culm receiving member is configured to rotate downward by the weight of a certain amount of culm gathered to form a dropper device, but the culm that is threshed with a mobile threshing machine and discharged may be long. In this case, it is difficult for the above-mentioned culm receiving member to catch the culm, and the focusing posture is disturbed. For this reason, the culm receiving member is moved and adjusted in the direction of the culm body of the culm so that the center of gravity of the culm and the center of the culm receiving member coincide, but in the conventional configuration,
The movement adjustment mechanism of this culm receiving member was complicated.

For this reason, this invention is constructed as follows.
That is, a receiving rod 4 bent in a plane to form a culm receiving surface 3 is placed on a receiving plate 2 which is rotatably provided at the ejecting culm discharge position 1, and this receiving rod 4 is A mobile threshing machine in which a part of a receiving rod 4 placed on a receiving plate 2 is pivotally mounted 5 in order to change the position of the culm receiving surface 3 toward the culm of the culm by inverting it on the plate 2. Dropper device.

This invention has the following technical effects due to the above-described configuration. That is, since the receiving rod 4 is bent in a plane, the culm receiving surface 3 can be formed on the front and back sides, and the part of the receiving rod 4 placed on the receiving plate 2 is attached to the pivot 5. By flipping the culm from front to back, the culm receiving surface 3 moves toward the tip of the culm and the base of the plant, making it easy to handle long or short culms. This can be done by simply reversing the rod 4, making it inexpensive and easy to operate.

Next, an embodiment of this invention will be explained with reference to the drawings.

A cutter machine frame 8 is mounted on the rear side of a combine harvester body 7 equipped with a traveling device consisting of a crawler 6, and a support shaft 10 is supported on the lower rear side of the cutter machine frame 8 via a bracket 9. A receiving plate 2 is pivotally attached to this support shaft 10, and the upper surface of the receiving plate 2 is held horizontally by a tension spring 11 stretched between the cutter machine frame 8 and this receiving plate 2.

Reference numeral 4 denotes a rod made of a single wire bent in a plane, which is placed on the receiving plate 2, and a part of the portion placed on the receiving plate 2 is pivotally attached 5 by a support member 12. Therefore, the receiving rod 4 is attached to the receiving plate 2 with its pivot portion 5 as the center.
It is reversed at the top, and the discharge culm receiving surface 3 protruding from the receiving plate 2 can be freely moved in the axial direction of the support shaft 10. In the state shown in FIG. 2, the bent end of the receiving rod 4 is projected laterally, but the end may be pivoted 5 onto the receiving plate 2 as shown in FIG. 3.

At the top of the cutter frame 8, there is a culm transfer device 13.
has been established. This culm transfer device 13 supplies the waste culm into the cutter frame 8 below during the transfer, or transfers the waste culm to a position beyond the cutter frame 8 and drops it.

14 is a guide rod that guides the culm falling from the culm transfer device 13 onto the receiving rod 4.

The weight of the culm accumulated on the receiving rod 4 causes the tension spring 11
If the tensile force becomes heavier than , the receiving rod 4 will rotate downward together with the receiving plate 2, and the discharged culms will be released into the field in a focused state.
