Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention receives a bundle of waste straws discharged from a conveyor device under a terminal end of a conveyor device which conveys a bundle of waste straws from a binding device, and receives a bundle of catches. The present invention relates to a combine straw discharge processing device provided with a dropper device that discharges these receiving bundles when the number reaches a set bundle number.

[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 valve that supports and maintains the receiving posture and a spring that returns from the releasing posture to the receiving posture (for example, Japanese Utility Model Laid-Open No. 60-27626).

[Problems to be solved by the device]

The receiving base is switched to the releasing position depending on the weight of the bundle of exhaust straws that acts simultaneously with the unlocking of the electromagnetic valve. However, since the pullback spring is operating, the receiving base returns to the receiving position side during the release. Therefore, the stack of waste straws, which is delayed when discharged, returns to the receiving posture and is sandwiched between a guide rod that guides the stack of waste straws discharged from the transport device to this stack, and the stack is received. However, there was a problem that the return to the receiving posture was not sufficient, and the unstable operation due to the use of the spring force could not be resolved. Further, it is difficult to match the timing at which the receiving base returns to the receiving posture with the timing for locking the electromagnetic valve, and the dropper device is not functioning sufficiently.

The purpose of the present invention is to make the operation of the dropper device more reliable by changing the attitude switching mechanism with respect to the receiving base, and to set the sensor for detecting the bundle of discharged straws to a reasonable position to set the bundle of set pieces. The point is to provide an easy-to-change number.

[Means for Solving the Problems]

The characteristic configuration according to the present invention is that the bundle of discharged straws discharged from the conveying device is received below the end of the conveying device that conveys the bundle of discharged straws from the binding device, and when the number of receiving bundles reaches the set number of bundles, they are received. In a combine straw discharge device that is equipped with a dropper device that discharges a bundle, swings between a receiving posture that receives the discharged straw bundle discharged from the transport device and a discharge posture that drops and discharges the received discharge straw bundle. The dropper device is equipped with a cradle that can be dynamically switched, and a forced drive device that switches the posture of the cradle is provided. The cradle is switched from the receiving posture to the releasing posture by one rotation of the forced drive device. After that, the drive arm of the forcible drive device and the receiving base are interlockingly connected with each other via an elastic material so that they can be oscillated to return to the receiving posture again, and the receiving base is received above the receiving base. Fall into space A detection sensor that detects the bundle of discharged straws and detects that the set number of bundles has been reached is provided, and a dropper control device that activates the drive device based on the detection operation of the detection sensor is provided. A position adjusting mechanism for moving and adjusting is provided, and its action and effect are as follows.

[Operation] Since the forcible drive unit, the drive arm, and the cradle are linked by an elastic material, the movement of the cradle with respect to the movement of the drive arm is flexible, thereby releasing the operation of the cradle. When returning to the receiving posture from the start position, the return operation should be started with a sufficient time for discharging the bundle of discharged straws, that is, even if the drive arm is rotating, the receiving base is released. It is possible to maintain the posture, and it becomes possible to reliably discharge the discharged straw bundle in accordance with the discharge operation time which varies depending on the weight and bulk of the stacked stacked straw stacks.

Then, the drive arm returns to move the receiving base from the releasing posture to the receiving posture, but the elastic action of the elastic material delays the returning operation of the receiving base relative to the returning movement of the drive arm. Since it is possible, it is not possible to return to the receiving posture too quickly and catch the stack of waste straws, and the locking action timing of the electromagnetic valve must be matched with the return operation timing of the receiving base in the receiving posture. No difficult adjustments are needed.

Then, for example, as shown in FIG. 2, a detection sensor (13) (contact type or a contact type sensor) for detecting the uppermost bundle of straws positioned on the top of the stacked bundles of straws discharged onto the receiving base (8). Although it is possible to detect when the set number of bundles has been reached by a structure such as non-contact type detection such as optical type detection, the vertical position of the detection sensor (13) can be adjusted by the position adjustment mechanism (18). ing. Therefore, it becomes possible to variably set the set bundle number of discharged straw bundles according to the volume of bundles that varies depending on the type of harvested stem culm and the cutting condition (clear weather or rainy weather) and the number of discharged bundles.

Further, the dropper control device in which the forcible drive device operates based on the detection operation of the detection sensor can automatically perform a series of operations for discharging when the set number of bundles of discharged straws is reached.

[Effect of device]

As a result, the receiving stand can be smoothly switched, and the bundle of discharged straw discharged to the surface of the field is not disturbed and the number of bundles is not excessive or insufficient, and the subsequent collection of discharged straw can be carried out smoothly. Was obtained in a state in which the structure was relatively simple and yet surely operated. In addition, a simple device that can adjust the vertical position of the detection sensor in the dropper control device makes it easy to change the set number of bundles of discharged straws and improves the setting work efficiency.
