The discharging pipe is internally and rotatably connected with a rotating shaft along the axial direction of the discharging pipe, the outer wall of the rotating shaft is fixedly connected with a helical blade, and a driving motor for driving the rotating shaft to rotate is installed on the top surface of the sealing plate.

A plurality of arc bulges are fixedly connected to the inner wall of each arc clamping plate, and arc grooves matched with the arc bulges are formed in the outer wall of each annular plate.

Each material guide pipe is provided with a control valve.

Adopt above-mentioned technical scheme, the utility model has the advantages of as follows:

1. when carrying out the bagging-off, put into between each arc splint and the annular slab with cement wrapping bag opening edge, control each die clamping cylinder's piston rod shrink to drive arc splint and be close to the annular slab and remove, and press from both sides tight wrapping bag opening, make the closing plate seal the wrapping bag, the arc arch of arc splint inner wall improves its leakproofness with the arc wall extrusion fit of annular slab outer wall.

2. The material in the discharge hopper falls to in the discharging tube to in leading-in to the wrapping bag through each passage, set up a plurality of passages and make the material that falls to in the wrapping bag distribute evenly, improve the speed of unloading simultaneously.

3. In the discharging process, the driving motor is controlled to drive the rotating shaft to rotate, and the spiral blade on the rotating shaft conveys materials in the discharging pipe to avoid blockage.

4. The effect of the suction fan is controlled, so that the raised dust generated in the falling process of the material is sucked into the dust collection box, enters the suction fan through the air suction pipe, and is conveyed into the material collection box through the exhaust pipe under the effect of the suction fan, and is prevented from being scattered to the external environment.
