It is conveyed by the hopper 3, and is dropped onto the grizzly plate 12 of the grizzly 7, which vibrates from side to side. Also. The clay that falls onto the grizzly 7, which is vibrated from side to side via the connecting rod 26 by the eccentric crankshaft 27 of the eccentric drive device 8, is sieved by the vibrating grizzly 7, and is separated between the grizzly plates 12 of the grizzly 7. Clay smaller than eye width is grizzly 7
Falling down from between the eyes. The remaining lumps of clay larger than the eye width of the grizzly 7 and foreign objects such as tree roots and wood chips move on the sloping surface of the vibrating grizzly 7 toward the left and right ends, and eventually the grizzly 7 The heavy lumps of clay and lumps fall from the edge of the flap damper 9 and land on the first flap damper 9, and the heavy clay lumps and lumps pivot downward through the damper plate 21 of the flap damper 9. foreign objects such as other tree roots and wood chips, and large lumps that were not shaken off after jumping off the first-stage flap damper 9 are moved to the next second-stage flap damper 9. Then, the remaining large lumps of clay and clumped stones fall down and are separated by the second-stage flap damper 9, and the foreign substances such as tree roots and wood chips that are finally left are removed by the second-stage flap damper 9. It passes over the top and is further discharged to the outside, so that only foreign substances such as tree roots and wood chips are finally completely separated and removed from side to side.
