In order to ensure the matching connection with the charging hopper 1, the charging hopper can be further matched and connected with a coal feeder (mainly considering the size compression, and meeting the requirement of smaller size of the coal feeder). This hopper 2 includes down: the device comprises a butt joint section 21 in butt joint with the feeding hopper 1, a lower vibration section 22 which is connected with a vibration device and avoids blocking, a lower transition section 23 which further transitionally shrinks the volume size of material circulation to meet the size matching requirement with a coal feeder, and a lower discharging section 24 which ensures smooth guiding and discharging. Of course, in order to ensure smooth conduction of the materials, the butt joint section 21, the lower vibration section 22, the lower transition section 23 and the lower discharging section 24 are integrally formed in sequence.

For the fit connection with the upper hopper 1, the lower end of the upper discharging section 14 extends into the upper end of the docking section 21. The inserted mode has guaranteed the smooth butt joint of material, and two segmentation structures avoid the restraint of vibration each other, improve the circulation effect.

Multistage formula structural design can further increase vibrating device's vibration effect, avoids because the too big defect that can't satisfy the vibration effect of volume, satisfies the smooth direction of material and passes through, improves the material and carries the effect.

In order to improve the sealing effect and avoid the phenomenon that dust flies at the joint to pollute the environment and seriously cause the waste of materials in the material conveying process.

The occlusion device 3 comprises: a hopper-shaped opening 31 which is communicated with the lower hopper 2, an inserting plate part 32 which can block the circulation space through the inserting plate, and a discharging part 33 which can smoothly communicate and release the material. Similarly, the hopper mouth 31, the insert plate portion 32, and the discharge portion 33 are integrally formed in this order to ensure the flow effect.

In order to improve the circulation effect and avoid the exposure of the material, the lower discharging section 24 extends into the hopper-shaped opening 31. Similarly, in order to improve the sealing effect of the joint, the materials are prevented from flying and polluting the environment. The outer walls of the lower discharging section 24 and the hopper-shaped opening 31 are provided with lower connecting rings 6, and a lower flexible sealing cylinder 7 is fixedly connected between the two lower connecting rings 6.

In order to realize the function of blocking circulation, the dredging device

In order to adjust the size of the flow, meet the requirement of slow transition and finally adapt to the size of the coal feeder, the feeding section 11, the upper transition section 12 and the upper discharging section 14 are all in a conical boss structure and are all in an upward opening structure; thereby ensuring the adjustment effect on the volume size of the material.

The feeding section 11 is adapted to the transition section of the raw coal bunker, and the feeding section 11 has a relatively large opening degree (i.e. the opening of the feeding section 11 is large), so that the feeding section and the transition section can be matched. In order to meet the regulation effect on materials, the inclination angle of the arc surface of the feeding section 11 is smaller than that of the upper transition section 12, and the inclination angle of the arc surface of the upper transition section 12 is smaller than that of the upper discharging section 14; each part contracts by a certain size to ensure the smoothness of circulation, and is arranged on two sides of the lower vibrating device 5 to ensure the vibrating effect of the lower vibrating device 5.

Similarly, the lower vibration section 22 is a vertical cylinder structure, and a lower vibration device 25 is arranged on the outer wall of the lower vibration section 22. The lower vibratory device 25 is located relatively lower than the upper vibratory device 15, primarily because the upper hopper 1 has a faster flow rate of material in the raw coal bin and a lower likelihood of plugging, and the upper vibratory device 15 is located lower. And inside hopper 2 down, because the material flows the in-process because the compression volume, the velocity of flow reduces gradually, so will descend vibrating device 25 to set up and lean on, avoid taking place to block up, and can compromise the inside material vibration effect of butt joint section 21 and lower changeover portion 23, guarantee the circulation effect.

This upper pad 131 downside has seted up the arc groove, and the protruding arc arch that is equipped with of lower pad 132 upside, the arc arch stretches into the arc groove setting, and the bellied diameter of arc is the same with the diameter in arc groove, guarantees smooth cooperation. The diameter of the connecting hole penetrating through the upper pad 131 and the lower pad 132 is larger than that of the screw 101, so that the buffering space of the nylon buffer pad 104 is increased, and the buffering effect is improved. An upper pad 131 is disposed adjacent the nut 102 and a lower pad 132 is disposed adjacent the nylon cushion pad 104.

Likewise, at least two nylon cushions 104 are arranged between the upper discharging section 14 and the connecting seat 9 of the butt-joint section 21. The number of nylon cushions 104 is also selected based on the size of the gap.

To avoid over-sizing the nut and undersizing the deformation support pad 103, it is preferable to provide a transition washer 105 between the deformation support pad 103 and the nylon cushion 104. The diameter of the deformable support pad 103 is greater than the diameter of the nut 102, the diameter of the transition washer 105 is greater than the diameter of the deformable support pad 103, and the diameter of the nylon cushion 104 is greater than the diameter of the transition washer 105. Diameter increase has in proper order guaranteed the requirement of nylon blotter 104 diameter, and the nylon blotter 104 of bigger diameter not only can guarantee the cushioning effect, can improve the inside diameter of nylon blotter 104 moreover, reduces the interact between feeding funnel 1 and the lower hopper 2.
