In addition, in the present embodiment, be embedded in the gear of the gyroaxis leading section that send dirt conveyer 50 outward and be meshing with each other, send the rotating speed of dirt conveyer 50 to handle the ratio constant of the rotating speed of cylinder 22 with sending the dirt mouth with being embedded in the gear that send the dirt mouth to handle the gyroaxis leading section of cylinder 22 outward.Therefore, can be held in by predetermined scale dimension send dirt handle cylinder 22 separate, by the amount of the object being treated that send dirt conveyer 50 to catch with by the amount of the object being treated that send dirt conveyer 50 to carry towards the place ahead.Also can be in the rearward end side that send dirt conveyer 50 and send the dirt mouth to handle the gyroaxis of cylinder 22, with gear, belt and belt pulley or chain and sprocket etc., send dirt conveyer 50 and the rotating ratio that send the dirt mouth to handle cylinder 22 to keep constant ground distribution driving force.

Fall the object being treated of below by being located at the hole (mesh) of handling in the cylinder net 24, (promptly handle the opposite direction of throughput direction of cylinder 22) by this conveyer 50 towards fuselage the place ahead and carry with sending the dirt mouth.This object being treated is put into sorting portion 17 again from being located at the dust-exhausting port 50a that send dirt conveyer 50 front ends.More particularly, object being treated is in the position that drops to (i.e. the top of the 1st conveyer 36) above the stream paddy plate 39 on the glume-shell screen 33.

In the present embodiment, send dirt conveyer 50 to be screw type conveyer, but be not limited thereto, also can be belt-type conveyer.In addition, also can be on Qian Liugu plate 30 by the position of sending dirt conveyer 50 to drop into object being treated again.

Below, according to Fig. 5, Figure 25 and Figure 26 sensor 51 is described.

Sensor 51 is used to detect the amount of the Lysimachia sikokiana that is deposited in the preceding stream paddy plate 30 of being located at sorting portion 17 front upper parts and glume-shell screen 33, thereby adjusts the aperture of glume-shell screen 33, mainly is made of contact 51a and the 51b of sensor portion.

Contact 51a is elongated tabular component, and the one end is installed on the gyroaxis of the 51b of sensor portion.The 51b of sensor portion is angle of revolution sensors such as resolver, swinging potential difference meter, rotary encoder, can detect the posture of the relative fuselage of contact 51a by the form of angle.

Such as shown in figure 26, be piled up in the thickness T [mm] of the above-below direction of object being treated on the glume-shell screen 33 (mixtures of paddy and cataclasm grass bits), according to above glume-shell screen 33 to the height H [mm] of the 51b of sensor portion, the length R[mm of contact 51a], by the angle of revolution of the detected contact 51a of the 51b of sensor portion

When

The time be expressed as 0＜T＜H-R, when

The time be expressed as T=H-R * cos θ.The angle of revolution of contact 51a

Definition like this: contact 51a towards under the time (when contact) with object being treated be zero, when contact 51a contact with the object being treated that is transported to the rear, when turning round towards the rear be on the occasion of.

On the other hand, in sorting portion 17, can separate by good accuracy in the scope of grass bits and paddy, increase as much as possible from the fall amount of glume-shell screen 33, wait the relation of thickness T [mm] of the above-below direction of the aperture of obtaining the glume-shell screen 33 of sorting process ability when maximum in advance and object being treated (mixture that paddy and cataclasm grass are considered to be worth doing) by experiment to grain sieve 32.

Then, according to from sensor 51 and the angle of revolution

The relevant information information of the accumulating amount of object being treated on glume-shell screen 33 and preceding stream paddy plate 30 (promptly about), the aperture of regulating glume-shell screen 33.

For example, only be piled into the mountain shape under the sensor 51 at object being treated, such occasion is not piled up in other place on glume-shell screen 33 and preceding stream paddy plate 30, according to by sensor 51 detected angles of revolution

The not talkative accumulating amount (, having estimated accumulating amount) that has correctly reflected the object being treated on actual glume-shell screen 33 and the preceding stream paddy plate 30 of the thickness T of obtaining [mm] than the accumulating amount of reality in this occasion with Duoing.Therefore, object being treated is distributed on glume-shell screen 33 and preceding stream paddy plate 30 equably, from the viewpoint of obtaining thickness T [mm] by good accuracy with see all important by the viewpoint that good efficiencies is carried out sorting.

In fact, swing by sorting portion 17 distributes object being treated equably on glume-shell screen 33 and preceding stream paddy plate 30, but only under the dust-exhausting port 50a that send dirt conveyer 50 front ends, particularly during the travel speed when when harvesting big (unit interval harvested material put into threshing portion 12 and sorting portion 17 amount many), be piled into the mountain shape sometimes from the object being treated that dust-exhausting port 50a falls.

Therefore, the installation site of sensor 51 is preferably the position of leaving slightly from " mountain " of the part that is produced by object being treated (putting into sorting portion 17 again by sending dirt conveyer 50), and is sent object being treated that dirt conveyer 50 puts into sorting portion 17 again and mixed by swing and dispose equally distributed position by holding object being treated that net 20 falls by this.

As Fig. 5 and as shown in Figure 25, in the present embodiment, the gyroaxis of threshing cylinder 21 central authorities (C-C of Central Line, the left and right sides shown in Figure 25) side of turning left partially from about the sorting portion 17, the gyroaxis that send the dirt mouth to handle cylinder 22 is inclined to one side towards right side side.Therefore, conveying the gyroaxis that send dirt conveyer 50 that send the dirt mouth to handle the object being treated that cylinder 22 takes place also from about the sorting portion 17 central authorities turn right partially, the object being treated that drops in the sorting portion 17 from dust-exhausting port 50a forms mountain 70 in central authorities from about sorting portion 17 toward the position of right avertence.

Sensor 51 is configured in the fuselage rear (being the conveyance direction downstream side of the object being treated of sorting portion 17) of the dust-exhausting port 50a that send dirt conveyer 50, and more leans on the position of past threshing cylinder 21 than central authorities about sorting portion 17.Therefore, the detected value that is piled up in the amount of the object being treated in the sorting portion 17 can not be subjected to the influence on mountain 70 and become from the accumulating amount of reality departing from bigger value, and, mixing and equally distributed position by swing by the object being treated that send dirt conveyer 50 to put into sorting portion 17 again with by holding the object being treated that net 20 falls, detect the amount of object being treated, so, can go out the accumulating amount of object being treated by good accuracy detection.

Even following either party ground configuration is satisfied in the position of sensor 51, also can obtain same effect, promptly, (1) send the fuselage rear (being the downstream of the throughput direction of the object being treated in the sorting portion 17) of the dust-exhausting port 50a of dirt conveyer 50, perhaps, (2) threshing cylinder 21 lower rear, than central authorities about sorting portion 17 more by toward the position of threshing cylinder 21.

In addition, in the present embodiment, the 51b of sensor portion of sensor 51 is angle of revolution sensors such as resolver, swinging potential difference meter, rotary encoder, but be not limited thereto, also can form such formation: the 51b of sensor portion of this formation is the switch of contact, when the predetermined angle of contact 51a rotation is above, carry out the break-make of this switch.In addition, also can use static capacity sensor etc.
