In addition, according to the present invention, the intermediate discharge means 30 is provided with a gumbulnet 31, a sand net 32, and a guide plate 33 in the middle region of the main body 10, and It is a structure that causes infinite circulation of the scraper 35 upward. As shown in FIG. 5, the gumbulnet 31, the sand net 32, and the guide plate 33 are in a stacked state, and as shown in FIG. 3, the slope that decreases from the front to the rear of the main body 10 is maintained. The intermediate discharging means 30 moves the scraper 35 to the gumbul net 31 on the upper side and discharges the small gumbul to the foreign matter discharging port 14 at the rear. The scraper 35 is mounted on the movable chain 36 so as to be transferred infinitely. The sand net 32 disposed under the gumbul net 31 discharges the falling sand to the sand outlet 15 at the side. The guide plate 33 disposed below the sand net 32 sends the falling secondary raw material to the lower discharge means 40.

In addition, according to the present invention, a structure in which the lower discharge means 40 is provided with a chasing plate 41 and a guide plate 43 in the lower region of the main body 10, and induces a chasing motion through the link 46 to be. The chafing plate 41 and the guide plate 43 of the lower discharge means 40 are in a stacked state and maintain a slope that decreases from the rear of the main body 10 to the front. A drive shaft 45 is rotatably installed on the upper side of the chamfer 41, and a link 46 for inducing a keying motion by a cam is connected between the drive shaft 45 and the guide plate 43. The chafing plate 41 has a fine perforation to serve as a key (winnowing basket), and the entrance becomes narrower toward the inclined upper side and communicates with the stone outlet 16. The guide plate 43 is bent at a steep incline toward the inclined lower side and communicates with the collecting port 12.

Thus, the intermediate discharging means 30 kneads the secondary raw material that has fallen to the scoring plate 41, and moves the heavy stones to the inclined upper side and discharges them to the stone outlet 16, and the third selected grains Silver is discharged to the collecting port 12 on the lower side through the guide plate 43 from the stalk plate 41. The airflow by the blowing fan 18 disposed under the lower discharge means 40 also serves to aid in the keying.

In this case, as shown in FIGS. 1 to 3, the intermediate driver 38 and the lower driver 48 may be connected using the same single motor. The drivers 38 and 48 operate the link 46 through one end of the drive shaft 45, and the other end of the drive shaft 45 operates the blower fan 18. In addition, a separate actuator for imparting vibration to the intermediate discharge means 30 may be installed.

On the other hand, the intermediate discharge means 30 and the lower discharge means 40 of the present invention is preferably installed in a drawer structure that can be withdrawn to the outside of the main body 10. The drawer structure means that it slides onto a rail installed on the inner surface of the main body 10. Accordingly, it is easy to replace the gumbul net 31 of the intermediate discharging means 30, the chafing plate 41 of the lower discharging means 40, and the like according to the type of grain (grain size).

In addition, according to the present invention, the controller 50 is connected to the main body 10, the upper discharge means 20, the intermediate discharge means 30, and the lower discharge means 40, and conveys grain and air by a set algorithm.

It is characterized in that the flow resistance of the means 20 is varied, the application of the excitation force of the intermediate discharge means 30 is regulated in response to a set condition, and the cleaning speed of the lower discharge means 40 is varied in response to the set conditions. .

The detection sensor 54 detects the grain size of the grain using a laser sensor method, and detects the input amount by a load acting on the front plate 21 or the rear plate 22. The camera 56 detects the state of separation of foreign substances through the analysis of the captured image, and at the same time assists in detecting the particle size and the amount of the detection sensor 54. Control algorithms corresponding to the signals from the detection sensor 54 and the camera 56 are stored in the memory of the controller 50 and executed.

As an example of operation, when the input amount of grains through the inlet 11 is temporarily increased, the upper actuator 28 is operated to lower the falling speed to maintain a constant processing speed. Nevertheless, if the amount flowing into the intermediate discharge means 30 increases, the excitation force of the intermediate discharge means 30 is increased while increasing the operation speed of the scraper 35, and when a foreign substance or stone is detected in the collecting port 12, the scaffolding 41 Fluctuates the speed of picking. If automatic control is insufficient according to the situation of the field, the operator can manually control each process through the touch screen 52, and optimization control is possible as such history is accumulated in the memory.
