The utility model discloses an adopt following technical scheme to realize: a prismatic shaft connecting structure of a screw conveyor comprises a front screw, wherein a connecting shaft is arranged at the front end of the front screw, a connecting sleeve is sleeved outside the connecting shaft, the shape of the inner cavity of the connecting sleeve is the same as that of the connecting shaft and is in clearance fit with the connecting shaft, a rear connecting shaft is further sleeved at the other end in the connecting sleeve, and the rear connecting shaft is arranged at the front end of the rear screw;
the connecting shaft is a front connecting prismatic shaft, the rear connecting shaft is a rear connecting prismatic shaft, the connecting sleeve is a prismatic connecting sleeve, and the inner cavity of the prismatic connecting sleeve is the same as the front connecting prismatic shaft and the rear connecting prismatic shaft in shape and is in a polygon shape.
Preferably, the device also comprises a bearing sleeved outside the prismatic connecting sleeve, a supporting sleeve is sleeved outside the bearing, and one end of the supporting sleeve is fixedly connected with the wall of the conveying pipe.
Preferably, the front connecting prismatic shaft, the rear connecting prismatic shaft and the inner cavity of the prismatic connecting sleeve are hexagonal.
Preferably, the bearing is an oil-free self-lubricating bearing.
The utility model has the advantages that:
(1) screw conveyer prism shaft connection structure, preceding connection prism axle and the back of many prisms are connected the prism axle and are passed through the butt joint of prism adapter sleeve, and the moment of torsion that transmission was connected to many prisms is big, joint strength is high, turns round that to decrease the probability also relatively lower, and conveying efficiency is higher.
(2) Screw conveyer prism shaft connection structure, be provided with oil-free lubrication bearing and support the cover, provide traction force for the butt joint department of preceding spiral and back spiral through supporting the cover for both concentric degree is higher, the efficiency of transport is higher, carry more steady of operation, the part loss rate reduces because the even running of equipment.
