Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is directed to a cradle for receiving a bundle of discharged straw discharged from the conveying device below the end of the conveying device for conveying the bundle of discharged straw from the binding device. And a dropper device equipped with a forced drive device for swinging the receiving table once to change the receiving position from the receiving position to the discharging position and then to return to the receiving position again. A combine sensor discharge straw provided with a detection sensor for detecting a bundle of discharged straws, and a dropper control device for operating the forced drive device when a counter for counting the number of detections by the detection sensor counts a set bundle number. Regarding a processing device.

[Conventional technology]

In the combine straw discharge processing device of this type, conventionally, in forming the dropper device, a receiving base that receives the discharge straw bundle discharged from the conveying device is pivotally movable up and down around a horizontal support shaft. It was provided with an electromagnetic cylinder that supports and maintains the receiving posture and a spring that returns from the discharging posture to the receiving posture (for example, Japanese Utility Model Laid-Open Nos. 60-27626 and 56-52936).

[Problems to be solved by the invention]

When the electromagnetic cylinder is unlocked, the receiving base is switched to the releasing position depending on the weight of the bundle of discharged straws, but since the pullback spring is acting, the receiving base is reversed to return to the receiving position side during the release. , The stack of discharged straws, which is delayed at the time of discharging, returns to the receiving posture and is caught between the receiving stand and the guide rod that guides the discharged stack of discharged straws from the conveyor to this receiving stand. There was a problem that the return to the posture was not sufficient, and the instability of the operation due to the use of the spring force could not be resolved. Also, it is difficult to match the timing when the receiving base returns to the receiving posture and the timing when the electromagnetic cylinder locks, so if you try to return and lock it correctly, the mechanism that links the electromagnetic cylinder and the receiving base with high precision Since it must be manufactured and the control of the control device must be performed with high accuracy, the cost is high.

The present invention makes the operation of the dropper device more reliable by modifying the attitude switching mechanism for the receiving base, and the discharging operation and the receiving operation of the receiving base without using high-precision parts or controls. It is an object of the present invention to provide a combine straw discharge processing device capable of favorably performing a posture return operation.

[Means for solving problems]

In order to achieve the above-mentioned object, the combine straw discharging device according to the present invention has the above-mentioned structure and has the above-mentioned structure so that the receiving base is oscillated one reciprocation by one rotation drive by the forced drive device. A drive arm that is driven to rotate once by a forced drive device is linked to the receiving base through a linking mechanism, and the linking mechanism operates the rotational movement of the drive arm and the swinging of the receiving base. A characteristic feature is that a spring that absorbs a deviation in the timing of the operation of is inserted.

The function and effect of this characteristic configuration are as follows.

[Action]

That is, the discharge operation of the bundle of discharged straws and the return operation of the receiving base to the receiving posture are performed through the linkage mechanism by driving the drive arm one rotation by the forced drive device. Is held by the drive arm and the linkage mechanism that have stopped in the state of returning to the return position, it can be stopped without locking. In addition, even if the drive arm is in the return operation state, the spring in the linkage mechanism delays the return operation of the receiving base so that the receiving base returns to its receiving posture quickly. It is possible to eliminate the problem that the bundle of exhaust straws is caught by passing it, and it is not necessary to adjust the timing of the returning operation.

[Effect of device]

Therefore, the forcible drive device has a simple structure in which the drive arm is driven to rotate once, and a spring is provided in the linking mechanism that links the drive arm and the receiving base. It is possible to obtain a structure that can avoid catching the bundle of discharged straws when returning to the operation, and since the receiving base can be securely fixed and held in the receiving posture, the drive control of the forcible drive device in the control device is simply the drive arm. It was possible to obtain a dropper device with a simple structure and at a low cost by simply controlling it by rotating it once.

〔Example〕

 Hereinafter, the present invention will be described with reference to the drawings.

At the rear of the combine traveling machine body, a threshing device (1), a waste straw conveying device (2), a waste straw shredding cutter (3), and a waste straw binding device (4) are provided behind the waste straw binding device (4). , A transport device (5) for transporting the bundle of discharged straws later is provided,
A dropper device (6) that receives the discharged straw bundles discharged from the transport device (5) below the rear end of the transport device (5) and discharges the received bundles when the number of received bundles reaches a set number. Is provided to form a combine straw discharge processing device.

Providing a support frame (5b) for supporting the sandwiching rail (5A) together with a protruding chain (5B) for sandwiching and transporting the bundle of discharged straws,
A vertical frame (7) is hung from the holding rail (5A) supporting frame, and a receiving stand (8) for receiving the bundle of discharged straw discharged from the carrying device (5) is laterally provided at the lower end of the vertical frame (7). It is pivotally supported to swing up and down around the support shaft (X). A swing arm (9) that can rotate integrally with the receiving base (8) was attached to the position of the horizontal support shaft (X), and was attached to the output shaft of a one-rotation motor as a forced drive device (10). The drive arm (11) and the swing arm (9) are connected by a tension spring (12) as a spring. While the drive arm (11) makes one revolution by the one-rotation motor (10), the swing arm (9) swings back and forth to switch the receiving base (8) from the receiving posture to the discharging posture, and
Return to the receiving posture again. Above, these are called a dropper device (6). The swing arm (9) and the tension spring (12) constitute a linkage mechanism (18).

On the other hand, in the transport path of the transport device (5), a sensor (13B) that is in contact with the discharged straw bundle and a sensor unit (13B) such as a potentiometer that senses contact swing of the contact (13A) ( 13) is provided to detect the discharged straw bundle sent by the transport device (5). Then, the detection result is the counter (1
4), the control device (15), the driver (16) and the like are output to the dropper control device (17) equipped with, the start signal is output to the one-rotation motor (10) when the set number of bundles. When the sensor (13) outputs a bundle sensing state for a set time or longer, the engine is stopped, etc. to stop the discharge of waste straw.

[Another embodiment]

(A) The sensor (13) may be a non-contact type such as light or ultrasonic waves.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the structure of the accompanying drawings by the entry.
