Abstract:
PROBLEM TO BE SOLVED: To improve the classification treatment capability of a pretreating device of soil improving equipment.
SOLUTION: A rotary cylinder 14 having screen openings 15 on its outer peripheral part is freely drivably and rotatably supported on a main body frame 11. Plural agitating vanes 14 are freely drivably and rotatably supported in this rotary cylinder 14. Cutting force, rotating force, friction force, etc., are acted by rotation of the rotary cylinder 14 and the agitating vanes 14 on the soil A which is carried in by a carrying-in conveyor 30 and is before the preliminary classification. The soil C after the pretreatment is discharged from the screen openings 15 to a transfer conveyor 38. On the other hand, inclusions B are discharged from a chute 32 to a transfer conveyor 34.
