The utility model drives the discharging cover up and down by the winch in cooperation with the wire rope, can adjust the discharging height of cement clinker, prevent a large amount of dust from being raised when cement clinker falls, collects dust by cooperation of the exhaust fan, the dust hood and the dust collecting box, reduces the harm to the staff, and makes the cement clinker loaded evenly by the material dividing assembly, thereby improving the loading efficiency.

[0004] In the existing technology, although a certain cement storage output effect can be achieved during use, there are defects: the existing automatic discharging device at the bottom of the cement silo lacks effective stirring to remove bubbles and optimize the discharging effect, and there is no top-down auxiliary discharging device, which causes the cement to run slowly during discharging, affecting the overall work efficiency. In view of this, we propose an automatic discharging device at the bottom of the cement silo to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problems existing in the background technology and proposes an automatic discharging device for cement silo bottom.

[0006] The technical solution of the utility model is as follows: an automatic discharging device for the bottom of a cement silo comprises a box body, a fixed block 1, a limiting ring, a limiting nail, a roller 1 and a roller 2, a fixed block 1 is arranged in the middle of the upper end of the box body, a rotating block is rotatably installed on the upper end of the fixed block 1, the upper end of the box body is fixed with a limiting nail through a mounting frame, a fixed block 2 is fixedly installed on the lower end of the limiting nail, the upper end of the fixed block 2 is fixedly connected to the limiting ring, a rotating ring is rotatably installed on the outer wall of the limiting ring, a roller 1 is arranged on the outer wall of the rotating ring, and rollers 2 distributed in a ring array are arranged on the outer wall of the rotating block.
