Bidirectional blade quick discharge type dual-purpose shafted quasi-spiral body of efficient double-crushing conveyor

The utility model relates to a bidirectional blade quick discharge type dual-purpose shafted quasi-spiral body of an efficient double-crushing conveyor, which is characterized in that an existing unidirectional blade tail slow discharge type dual-purpose shafted quasi-spiral body is improved into the bidirectional blade quick discharge type dual-purpose shafted quasi-spiral body, and the bidirectional blade quick discharge type dual-purpose shafted quasi-spiral body comprises a quasi-spiral rotating shaft and dual-purpose bidirectional blades; the dual-purpose bidirectional blade comprises a forward material pushing blade and a reverse material pushing blade, the forward pushing blades and the reverse pushing blades are obliquely welded on the left section, the right section, the left section, the right section and the left section of the rotating shaft at intervals in a spiral mode, a quasi-spiral rotating shaft with the forward pushing blades is formed on the left section of the rotating shaft, and a quasi-
