装置。A device having a flow path switching valve provided in the hopper so that the opening at one end alternately faces one of a pair of cylinders having an opening communicating with a hopper into which fresh concrete is charged by swinging. The valve is disposed on both sides of the flow path switching valve, and the opening at one end faces one of the cylinders due to the swinging of the flow path switching valve, and the opening at the other end is oriented substantially upward. a pair of guide members that are directed toward each other and communicate with the inside of the hopper; and a cover that is attached to the guide members and the flow path switching valve to cover the gap therebetween, and that is curved along the swing locus of the flow path switching valve. 1. A flow path switching valve device for a concrete pump, comprising: a member.
