DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a needle shaft on which a needle for winding a tying string around an culm bundle is attached.
The culm which is housed in the transmission case and supported on the shaft, and the other end of the shaft is fastened to a binding guide plate for receiving the culm to be conveyed and condensed, and the culm is supplied with the culm and stopped until a predetermined amount is reached. The present invention relates to a focusing device in which a receiver is formed in a substantially H shape when viewed from a transfer direction.

[0002]

2. Description of the Related Art For example, in a binding machine mounted on a combine or the like, a grain stalk cut by a combine harvester is supplied to a threshing machine to be threshed, and the threshed grain culm becomes a waste culm. To the binding machine. The culm is transferred and bundled by the packer of this binding machine, received in a U-shaped culm receiving member viewed from the transfer direction, stopped while being bundled until a predetermined amount is reached, and when reaching the predetermined amount, the power is transmitted. The needle attached to the needle shaft, which has one side inside the case and is supported in a cantilevered state, rotates, and the tying string attached to this needle is wrapped around this bundle of culms and bound. The tied bundle is discharged from the tying machine to the outside of the machine.

[0003]

The needle shaft on which the needle for winding the tying string around the culm bundle is mounted is housed in a transmission case and is supported in a cantilevered state. , The needle oscillates, and the tying string is not wound correctly, resulting in a tying error.
The culm receiving device that receives and stops the supply of the culm that is transferred and bundled has a U-shape and has no lower portion, so the culm enters from the lower portion of the culm receiving portion, and the culm that has entered is not bound. However, the present invention is intended to solve these problems.

[0004]

According to the present invention, a needle shaft 52 for mounting a needle 51 for winding a tying string (a) around a bundle of bundles of grain and a shaft at an end thereof, and one side of the needle shaft 52 are provided. A transmission case 46 that is installed and supported axially; a packer 47 that is attached to the transmission case 46 to transfer and bundle the culm;
A binding guide plate 48 for receiving the root of the culm is provided, and the shaft end on the other side of the needle shaft 52 is attached to one side of the tying guide plate 48, and the culm to be conveyed and focused is provided. The culm receiving device 50 for receiving and stopping until reaching a predetermined amount is formed in a substantially H-shape as viewed from the transfer direction, and provided.

[0005]

According to the binding machine mounted on the combine, the combine stalks cut by the combine reaper are fed to the threshing machine and threshed by running the combine in the field, and the threshed stalks are It becomes culm and is supplied from the threshing machine to the binding machine. This culm is condensed while being transferred by the packer 47 of the binding machine, and has a substantially H-shaped culm receiver 5.
It is received at 0 and stopped while focusing until it reaches a predetermined amount. When the predetermined amount is reached, one end is mounted inside the transmission case 46 and is pivotally supported, and the other end of the shaft is supported by the binding guide plate 48 for receiving the root side of the culm to be conveyed and condensed by the packer 47. The needle 51 attached to the needle shaft 52 which is fastened to one side and supported at both ends is rotated, and the tying string (a) attached to the needle 51 is wound around the bundle of bundles of culms. The bundle of culms that have been attached and bound is discharged from the binding machine to the outside of the machine.

[0006]

A needle shaft 52 having a needle 51 mounted thereon
Since the both ends are supported by both the transmission case 46 and the binding guide plate 48, the strength is increased, the needle 51 can be prevented from swaying, the binding error can be prevented, and By forming the receiver 50 into an H shape and extending the lower part, it was possible to prevent the culm from entering from the lower part, and to eliminate the culm discharged without being bound.
