PROBLEM TO BE SOLVED: To provide a snake pump in which a stator casing, a helical rotor, a drive rotary shaft, and a drive shaft of a drive deceleration motor can be disassembled and assembled rapidly and easily from a food input casing of the snake pump.SOLUTION: The food input casing 2 is arranged on a machine casing 1. A stator casing 4 is arranged between parallel guide rods 3, 3 extending forward from the machine casing 1 on both sides of the input casing 2. The casing 4 is supported between the parallel guide rods 3, 3. Female screws 7, 7 are respectively screwed in male screw-threads 3', 3' respectively formed on the extended front ends of the guide rods 3, 3. Collars 8, 8 are respectively interposed between the female screws 7, 7 and the front flange 5'. A rear end of the stator casing 4 is in press-contact with an outer peripheral upright surface 9' of a rotor insertion hole 9 pierced on a front wall 2' of the input casing 2 through the collars 8, 8 and the flanges 5, 5' by the rotation of the female screws 7, 7. |
