Claims

[Scope of Claim for Utility Model Registration] (1) A gate pivot for pivotally supporting the gate on the hopper body so as to open and close the lower opening surface of the cylindrical hopper body, a driven part for opening and closing the gate, and a first a first pivot connecting the links, and a first link and a second
a second pivot that connects the link to the hopper body; and a third pivot that pivotally supports the second link on the hopper body, and the second link is rotated around the third pivot. Therefore, in the gate opening/closing device of the hopper configured to open and close the gate, at least one of the pivot parts for the gate, the first pivot part, the second pivot part, and the third pivot part is for the gate. The pivot, the second pivot, and the third pivot are formed by a first connector having a pivot protruding to one side and a second connector having an insertion portion through which the pivot is inserted, and the gate is opened and closed. A stopper is provided on one of the two connecting bodies and engages with the outer edge of the other so as to stop the first and second connecting bodies from moving in the axial direction within the corresponding rotational range, The invention is characterized in that a groove-like notch is provided on the outer edge where the stopper is located at a rotational position out of the range, through which the stopper passes, so that the two connecting bodies can be separated by allowing relative axial movement. Hoppa gate opening/closing device. (2) A hopper attachment device for removably attaching a cylindrical hopper body to a base body, wherein a first member provided on the hopper body and having a notch portion opened to the base body side at the edge of the base body side; a second member provided on the base body side that has an engaging portion that engages with the inner edge of the notch and supports the hopper body in this engaged state; and a second member provided on the side of the hopper body or a side of the hopper body from the base body a recess provided in the side plate protruding toward the direction; and a convex portion that fits into the recess when the notch is engaged with the engaging portion; in this fitted state, the notch is removed from the engaging portion The side plate or the hopper locks the movement of the hopper body in the direction in which the hopper body is disengaged, and also allows the hopper body to move in the direction in which the notch is disengaged from the engagement portion with the convex portion removed from the recessed portion. A hopper mounting device characterized by comprising a locking portion provided on a side surface of a main body. (3) The hopper mounting device according to claim (2), wherein the first member is provided on the base side, and the second member is provided on the hopper main body.
