[0003]   That is, the above-mentioned sorting device swings below the crimp net arranged directly above the handling cylinder. It allows the sorting wind to be sent to the sorting board in the direction of Kara so that it can leak through the swinging sorting board. The incoming grains are selected by wind.

[0004]   And, the rocking sorter is provided with a chaff sheave, and the chaff sheave is Plate-shaped fins extended in the width direction are opened at regular intervals in the front-rear width direction between the left and right support plates. Multiple fins, and each fin can be swung in the front-back direction. The tilt angle is adjusted so that the amount of grain leakage can be adjusted.

[0005]

[Problems to be solved by the device]

  However, if the rice is wet due to morning dew, etc., increase the angle of inclination of the horizontal rail. Even if it is adjusted to increase the grain leakage, the dust will adhere to each fin and the grain leakage Is significantly hindered, and eventually dust etc. accumulates and clogs the fins, There was a problem that the computer could not perform the sorting function.

[0006]

[Means for Solving the Problems]

  Therefore, the feed pan and the chaff sheave of the swing sorter that swings back and forth are supported. An anti-clogging body is installed directly above to be slidable back and forth in the left-right width direction. Prevents clogging of the same dust by forming a frame in the shape of a rectangular frame with multiple horizontal rails and connecting rods A combine sorting apparatus characterized by periodically swinging the body left and right Is intended to be provided.

[0007]   In addition, the feed pan and chaff sheave of the swing sorter that swings back and forth are supported directly. Prevents dust clogging in the upper part so that it can slide back and forth in the left-right width direction to prevent dust clogging Horizontal left / right reciprocating sliding speed change to make the left / right reciprocating sliding speed proportional to the machine's running speed. Another feature is that the additional means is provided.

[0008]

[Action]

  When sorting the grain of cut rice with a rocking sorter, use the rocking sorter. While swinging the board back and forth, leak grain through the feed pan and chaff sieve. At this time, if the harvested rice is wet due to morning dew, etc., The dust clogging prevention element placed directly above the feed pan and chaff sheave is moved in the left-right width direction. Slide it back and forth to attach dust etc. to the horizontal rail that forms the same dust clogging prevention body. The dust pan and chaff sheave do not adhere to dust, and these sorting functions are performed. It can be secured well.

[0009]   The dust clogging prevention body does not always slide back and forth, By sliding back and forth, the drive load of the drive source of the body that prevents clogging of dust etc. can be minimized. Thus, it can be economically and efficiently operated.

[0010]   In addition, the left and right reciprocating sliding speed changing means changes the left and right reciprocating sliding speed of the dust clogging prevention body. Is proportional to the traveling speed of this machine, In other words, when the amount of cutting, the amount of cutting and the amount of threshing are large, the clogging preventive body such as dust slides back and forth quickly By doing so, a large amount of dust, etc. can be reliably attached to the horizontal rail, and the swinging sorting board's sorting function Can be satisfactorily secured.

[0011]   On the other hand, when the traveling speed of the machine is low, that is, when the cutting amount and the threshing amount are small. In this case, the anti-clogging body is gently slid to the left and right to reciprocate, and the rocking sorting board has a sorting function. And the economical efficiency of the drive load of the drive source of the body that prevents clogging of dust, etc. can do.
