パのゲート開閉装置。[Claims for Utility Model Registration] (1) A gate for opening and closing the lower opening of a cylindrical hopper body is pivoted to the hopper body by a gate shaft, and the gate is rotated around the gate shaft to the open position. A hopper gate opening/closing device configured to change between a closed position and a closed position, comprising: a driven part provided on the gate apart from the gate axis; and a pivot provided on the hopper main body parallel to the gate axis; A first position that is pivoted on this pivot and is away from the pivot position is attached to the driven part.
a second link connected via a link and provided to open and close the gate by being rotationally driven around the pivot shaft, and the second link is connected to the second link through a link and is provided to open and close the gate when the gate is in the closed position or when the gate is in the closed position and in the open position. The hopper gate opening/closing device is characterized in that the pivot shaft, the driven part, the first and second links, and the connecting shaft are arranged in a straight line or in the vicinity thereof in any position. . (2) In the hopper gate opening/closing device according to claim (1), the second link is located on the first link coupling side or on the opposite side to the first link coupling side with respect to the position where the second link is pivotally supported on the pivot shaft. When the gate is in the closed position, the driven part, the first link,
A gate opening/closing device for a hopper, comprising a locking portion that engages either one of the coupling shafts of the driven portion and the first link to lock rotation of the gate in the opening direction. (3) The first and second gates, which open and close the opening at the lower end of the cylindrical hopper body, are pivotally supported on the hopper body by respective gate shafts, and rotated about the gate shafts to the open position. In a hopper gate opening/closing device configured to change to a closed position, the hopper gate opening/closing device according to claim (1) or (2) provided in the first gate, and the second gate opening/closing device provided in the second gate. The second gate is located away from the gate axis.
A gate opening/closing device for a hopper, comprising: a driven part; and a third link linking the second driven part and the first gate so that the second driven part and the first gate are opened and closed together.
