Claims

[Claims for Utility Model Registration] Closing and opening are accomplished by connecting a pair of half-containers with their open ends facing each other through a hinge, and driving cylinders with both ends attached to each of the half-containers. A device for mechanically restraining and maintaining the closed state of the hopper, which includes a loose fitting mounting member for attaching one end of the cylinder to one of the half-containers with a predetermined distance of play in the cylinder driving direction; a pair of locking members attached near the open end of each of the half containers so as to abut each other when closed; and a pair of locking members that are in contact with each other from a direction along the open end so as to come into contact with each other. a restraint member capable of restraining and holding the state; a support member attached to the one half-container and movably supporting the restraint member in the engagement direction; one end of the cylinder is located at the proximal end of the play; When the restraint member and the locking member are engaged, and when one end of the cylinder is at the far end of the play, the restraint member and the locking member are disengaged from each other. A hopper comprising a wire connecting one end to the restraining member, and a spring interposed between the restraining member and the support member to press the restraining member toward the locking member. Automatic locking device.
