Claims

[Scope of utility model registration request]

The screw is comprised of a screw consisting of a screw rod and a screw blade, and a casing that rotatably houses the screw, the screw is separable at the screw rod, and the divided screws are connected via a joint. In a screw conveyor, one of the divided screws connected to each other has a small-diameter shaft protruding from the end face of the screw rod, and the shaft part of the other divided screw has a small diameter shaft protruding from the end face of the screw rod of the other divided screw. A fitting hole into which the parts can be fitted is provided, and recessed portions facing each other are provided on the outer peripheral surface of the screw rod forming the fitting hole, and the axes of the screw rods coincide with the recessed portions. The first opening inward
A pin hole is provided, and a second pin hole whose axis coincides with the first pin is provided in the shaft portion, and when the shaft portion is fitted into the fitting hole, the pin hole extends between the first pin hole and the second pin hole. A connecting pin with a length smaller than the outer diameter of the screw rod is inserted into the two recesses, and the connecting pin retaining plate has a shape that prevents the outer surface from protruding from the outer circumferential surface of the screw rod when it is fitted into the recesses. The screw is fitted to hold down both ends of the connecting pin, and the retaining plate is fixed to the screw rod via a bolt, and the head of the bolt is sunk into the outer surface of the retaining plate.
