    • In a continuous unloader, in which an endless bucket conveyor is passed around an upper sprocket, a base sprocket therebelow and a distal sprocket in front of the upper sprocket, the base sprocket and the distal sprocket are connected to a lower end of a frame which supports the upper sprocket via a link mechanism which lowers the base socket and the distal socket when approaching each other and raises them when separating from each other. The common link mechanism causes the base sprocket and the distal sprocket to move toward and away from each other and ascend and descend, so that the continuous unloader is made simple in construction and small in weight. Also, complicated control is not necessary and a manufacturing cost is made low. The link mechanism may comprise a main link connected at one end thereof to the lower end of the frame and at the other end thereof to the distal sprocket, an auxiliary link connected at one end thereof to an intermediate point of the main link and at the other end thereof to the base sprocket, and a stay link connected at one end thereof to an intermediate point of the auxiliary link and at the other end thereof to the lower end of the frame. Such link mechanism enables the base sprocket and the distal sprocket to move toward and away from each other and to ascend and descend.
    • 在连续的卸载机中,环形斗式输送机绕着上链轮传递,底座链轮和下链轮前面的远端链轮,底链轮和远端链轮连接到框架的下端, 通过连杆机构支撑上链轮,当连接机构相互接近时,底座和远端插座相互下降,并在彼此分离时升高。 公共连杆机构使基部链轮和远端链轮相互移动并上下移动,使得连续卸载机构造简单,重量轻。 此外,不需要复杂的控制,并且制造成本低。 连杆机构可以包括在其一端连接到框架的下端并且在其另一端处连接到远端链轮的主连杆,辅助连杆在其一端连接到主连杆的中间点 其另一端连接到基部链轮,以及在其一端处连接到辅助连杆的中间点并且在另一端连接到框架的下端的撑杆连杆。 这种连杆机构使得基座链轮和远端链轮能够彼此移动并远离彼此并且上升和下降。
