  In addition, each cleaning member 30 includes a pair of operation cables 37a and 37b that are alternately pulled by a rotational drive of a drive motor 34, a balance arm 38 that reciprocates, a balance arm shaft 39, and a swing arm 40 that reciprocates. In order to reciprocate in the left-right direction via an interlocking mechanism such as

  When the drive motor 34 is driven, the pair of operation cables 37a and 37b connected to the crank pin 36 are alternately pulled by the rotation of the crank arm 35, and the balance arm shaft 39 is rotated by the reciprocating rotation of the balance arm 38. The swing arm 40 reciprocally swings left and right as the center. The cleaning member 30 connected to the swing arm 40 via the connecting pin 40a and the long hole 41 is forcibly reciprocated in the left-right direction. Is set so that the swing speed of the swing sorting shelf 15 swinging in the front-rear direction is faster. That is, the horizontal swing speed of the cleaning member is set to be slow so as not to hinder the backward feeding action by the swing sorting shelf. The drive motor 34, the crank arm 35, the crank pin 36, the cable 37, the balance arm 38, the balance arm shaft 39, and the swing arm 40 constitute a drive mechanism.

  Further, the swing sorting shelf 15 swinging in the front-rear direction has the number of swings per unit time as A times / second and the swing stroke as Bmm, and the cleaning member 30 swinging in the left-right direction has this unit time. When the number of swings per hit is C times / second and the swing stroke is Dmm, a relationship of A × B> C × D is set. That is, since the moving amount per unit time of the sorting processed product on the swing sorting shelf 15 is larger than the moving amount in the left-right direction by the cleaning member 30, the sorting processed product can be swung back without stagnation. As a result, the desired swing sieve selection can be performed satisfactorily.

  The crank pin 36 and the operation cable 37b are connected and held via a spring 42 and a plate 43 so that an excessive load is not applied to the cable 37.

  When the drive motor 34 is operated by engaging the threshing clutch with the threshing clutch lever 45, the drive switch 46 to the drive motor 34 is automatically turned on, and the drive motor 34 drives the cleaning member 30 to start swinging motion. Linked configuration. Since the swinging operation of the swing sorting shelf 15 and the cleaning member 30 is started by entering the threshing clutch, it is possible to effectively perform the cleaning action and the sieve screening while exhibiting the respective functions.

  The cleaning member 30 is interlocked to start a swing operation after a predetermined time has elapsed after the threshing clutch is engaged. According to this, it is possible to remove the swarf on the chaff sheave while the swarf is sent rearward after the swing drive of the swing sorting shelf 15 is started until a newly sorted processing product is introduced. Cleaning performance can be improved.

  Further, if the operation stop of the cleaning member 30 is configured to be stopped at the same time as the threshing clutch “off”, the driving of the cleaning member 30 is stopped at the time of the threshing stop when the newly selected processed material is not charged. It is possible to ensure durability. In addition, after the threshing clutch is turned off, the cleaning member 30 can be operated and stopped until a predetermined time has elapsed, and the load on the scraper 29 at the next start-up is reduced by stopping the top surface of the sheave after cleaning. can do.

  The operation (swinging) speed of the cleaning member 30 is variably controlled in accordance with the sensing amount of the layer pressure sensor 47 that senses the amount of the sorting processed product provided on the transfer shelf 16 of the swinging sorting shelf 15. When there is a large amount of sorting processed products, the swinging speed of the cleaning member 30 is increased, and when it is small, the swinging speed of the cleaning member 30 is decreased to optimize the processing speed.

  That is, the detection result of the processing amount by the layer pressure sensor 47 is input to the controller 48, and the rotational speed of the drive motor 34 is detected by the speed detection sensor 49 and input to the controller 48. When it is determined that the operating speed of the cleaning member 30 with respect to the amount of the sorted processed product is slower than a preset speed, the rotational speed of the drive motor 34 is increased, and the cleaning member 30 with respect to the amount of the sorted processed product is increased. If it is determined that the operating speed is fast, the rotational speed of the drive motor 34 is decreased. In short, by changing the rocking speed of the cleaning member 30 according to the amount of the sorting processed product and rocking it at high speed when there are many, it is possible to reliably remove the deposits on the sheave.

  In the swing speed control of the cleaning member 30 according to the amount of the sorting processed product, the swing speed of the cleaning member 30 can be changed according to the cutting work speed, the dry humidity of the crop, or the like. During low-speed work or dry crop conditions, the swinging speed of the cleaning member 30 is slowed to reduce the load on the cleaning member 30 and the drive unit. 30 functional effects can be enhanced.

  Further, it is convenient to provide means for changing the swing speed of the cleaning member 30 in the vicinity of the operation seat, and the operation speed can be easily adjusted.
