Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bundled culm discharging device for a combine knotter, and more particularly to a bundled culm discharging device for a knotter equipped with a conveying device for discharging the bundled culm in a state where it stands upright in the field with the bundled culm facing down toward the plant. This invention relates to a culm release device.

A conveying device that grasps the tip side of the bundled culm and transports it with the base side hanging down to the bundled culm release position of the combine knotter, and then releases the bundled culm in a state where it stands upright in the field. The present applicant et al. has proposed a system equipped with the following.

In this case, a particular problem arises when transferring the bundled culms bound by the knotter to the conveying device.
If the stock side does not droop quickly when the tip side is being held and moved, the posture of the bundled culms being transported by the transport device will be disturbed, and the bundled culms that fall from the transport device will not be able to stand firmly on the field. There is no such thing.

The present invention has been conceived in view of the above circumstances, and the knotter is located at a position where the knotter releases the bundled culm, at a position behind the position where the conveying device clamps the tip side of the bundled culm, and with the root side of the bundled culm facing downward. By disposing a pressing member that presses down, the bundled culm whose tip side is held by the conveyance device is immediately hung down to maintain a constant conveying posture, and the bundled culm released from the conveyance device is placed in the field. To provide a bundling culm discharge device for a combine harvester which can be surely erected.

Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings.

In the figure, reference numeral 1 denotes a knotter that is attached to the rear of a combine harvester (not shown) and binds the threshed culms, and a conveying device 2 is connected to the knotter 1 at the binding and culm release position. This conveying device 2 grasps the tip side of the bundled culm bound by the knotter 1, transports it with the plant base side hanging down, and drops it from the end of the conveyance so that the bundled culm stands upright on the field. It is for discharging, and is equipped with a conveyor belt 3 made of an endless chain, a guide plate 4, a guide rod 5, a pinning rail 6, etc. is guided to the conveying band 3 side, the tip side of the bundled culm is pinched and conveyed between the guide rod 5 and the conveying band 3, and the tip side of the bundled culm is transferred from the guide rod 5 to the pinching rail 6.

On the other hand, a vertically rotating rotor blade 7 is pivotally supported on the stock side of the bundled culm at the bundled culm release position of the knotter 1.
Rotational power is received from the rotational drive section of the engine via a chain transmission system 8. and rotor blade 7
rotates so as to press the base side of the bundled culm downward, but the timing of this pressing is slightly later than the time when the tip side of the bundled culm is clamped by the guide rod 5 and the conveyor belt 3 (delayed). It is set as follows.

Note that the rotor blade 7 is not limited to the one in this embodiment, and may be configured in a star wheel shape or a crank finger shape, for example.

In such a configuration, the shed culms that have been harvested and threshed by the combine harvester are tied together by the knotter 1 and released in a substantially horizontal lateral position. Then, the discharged bundled culm is guided toward the conveying belt 3 side by the guide plate 4 and guide rod 5 of the conveying device 2, and immediately after being held between the conveying belt 3 and the guide rod 5, the bundled culm is bundled and discharged. The root side of the culm is pressed downward by the rotor 7. Therefore, in the bundled culm, the tip side is the conveyor belt 3.
When it is clamped by the guide rod 5, the stock side is immediately lowered, moves while being held in a constant posture without any delay, and moves from the guide rod 5 to the clamping rod 6.
It is then transferred to the end of the conveyance, where it falls from the end of the conveyance and is securely erected on the field.

As described above, according to the bundled culm discharging device for a combine knotter of the present invention, the bundled culm is conveyed to the bundled culm discharge position of the knotter 1 in an attitude in which the tip side thereof is held and the stock side is hanging down. A conveying device 2 that drops the bundled culm and discharges it in a standing state on the field is installed in series, and the knotter 1 is at the bundled culm release position from the time when the transportation device 2 clamps the tip side of the bundled culm. Rotary blade 7 that pushes down the stock side of the bundled culm with a delay
Since the (pressing member) is arranged, when the tip side of the bundled culm is pinched, the stem side is immediately hung down and held in a substantially constant posture, so that the end of the conveyance of the conveyance device 2 The bundled culms that are released and fall from the plant are securely erected in the field with the stock side facing down, promoting the drying effect.
