Following technical proposal can be used to realize in the above-mentioned purpose of the utility model: a kind of flexible screw conveyor, including
It is fixedly connected with the rigid pipe of support, flange a thereon, feed opening is provided on the rigid pipe and is fixed in end and motor
Connection；The output shaft of the motor is fixedly connected with spiral, wherein further includes flexible pipe, impeller chain, the flexible pipe passes through it
The flange b of end is fixedly connected with the flange a；The impeller chain includes impeller hub, universal-joint fork, and the impeller hub exists
Both ends are fixedly connected with the universal-joint fork, and the universal-joint fork is connect with cross pivot hinge, the cylindrical surface of the impeller hub
On be fixedly connected with blade；It the impeller chain and the flexible pipe almost coaxial and is enclosed in wherein.
Preferably, the blade is arranged relative to the axis of impeller hub with same angle tilt.
Preferably, the inclined direction of the blade on all impeller hubs is identical.
Preferably, the length of the spiral is less than the length of the rigid pipe.
Preferably, discharge port is not stretched out in the front end of the impeller chain.
Preferably, the flexible pipe is the interior rubber tube for having helical form steel-wire carcass.
The utility model have the advantages that compared with prior art guarantee conveyer it is flexible under the premise of, due to
Flexible shaft using concatenated candan universal joint as conveying blade improves the abrasion resistance properties of flexible shaft；Conveying blade can
To be fixed on impeller hub using cheap welding method, manufacture difficulty and cost are reduced.
