PURPOSE:To provide the excavating part of a backet elevator with possibility to deform projectingly, for the purpose of unloading the corners of a hatch, by supporting the grasp part by an expansion/contraction device as well as to lessen the width of the excavating part by tilting the excavating part of continuous unloader. CONSTITUTION:At the undermost part of a backet chain type elvator 1 supported by the unloader body, sprockets 2, 3 are installed above the below in such a way that the backet chain 4 can have an appropriate inclination, and these two are coupled by a connecting rod 5 so as to keep a constant distance. The sprocket 3 is supported by two expansion cylinders, one 7 installed rotatably at a frame 1 of the backet chain type elevator with a pin 6 and the other 9 installed rotatably at another frame with a pin 8. The sprocket 2 is supported by another expansion cylinder 10 installed rotatably with the pin 8. |
