In some embodiments, the vibration spring 3 includes a first vibration spring 301 and a second vibration spring 302. The vibration rod 2 is provided with a stopping part 201 positioned at the outer side of the discharging section 102, the first vibration spring 301 is positioned at the outer side of the discharging section 102, two ends of the first vibration spring 301 are respectively stopped at the stopping part 201 and the outer wall of the bin of the discharging section 102, the second vibration spring 302 is positioned in the discharging section 102, and two ends of the second vibration spring 302 are respectively stopped at the vibrating plate 4 and the inner wall of the bin of the discharging section 102.
As shown in fig. 3 to 7, the first vibration spring 301 is sleeved on the vibration rod 2, two ends of the first vibration spring 301 are respectively stopped on the stopping part 201 and the bin outer wall of the discharging section 102, the second vibration spring 302 is sleeved on the vibration rod 2, and two ends of the second vibration spring 302 are respectively stopped on the vibration plate 4 and the bin inner wall of the discharging section 102, so that the first vibration spring 301 and the second vibration spring 302 are convenient to install.
Specifically, when the vibration lever 2 moves in a direction away from the outfeed section 102, the first vibration spring 301 is stretched, and the second vibration spring 302 is compressed; when the oscillating bar 2 moves in a direction approaching the outfeed section 102, the first oscillating spring 301 is compressed and the second oscillating spring 302 is stretched. The vibration rod 2 makes reciprocating vibration under the action of the elastic force of the first vibration spring 301 and the second vibration spring 302, which is beneficial to improving the buffering effect on the vibration rod 2 and prolonging the service life of the vibration spring 3.

In some embodiments, the outfeed section 102 has a square taper, and the angle between any side wall of the square taper and the horizontal plane is greater than or equal to 75 °.
For example, the angle between any side wall of the square cone and the horizontal may be 75 °, 78 ° or 80 °. Due to the high moisture and fine granularity of the pulverized coal, the pulverized coal is extremely easy to harden on the bin wall of the discharging section 102 of the pulverized coal bin, and if the included angle between any side wall of the square cone and the horizontal plane is too small, for example, 60 degrees or 70 degrees, larger friction force exists between the pulverized coal and the inner side wall of the square cone, so that the pulverized coal is difficult to discharge and is easier to block. Through being square taper with ejection of compact section 102, and the contained angle between arbitrary lateral wall of square taper and the horizontal plane is greater than or equal to 75, is favorable to reducing the frictional force between buggy and the ejection of compact section 102 storehouse inner wall, further is favorable to reducing the risk that buggy takes place to block up in ejection of compact section 102.

The discharging section 102 is further provided with a second perforation (not shown in the figure), and the pumping rod 702 extends into the discharging section 102 along the axial direction of the second perforation and is connected with the vibrating plate 4, and the vibrating plate 4 can drive the pumping rod 702 to pump.
The main pipeline 8 is communicated with the air outlet 7011 through a one-way valve (not shown in the figure), the inlet end of the one-way valve is arranged towards the air outlet 7011, a plurality of air ejector pipes 9 are arranged on the discharge section 102 at intervals, the air inlet ends of the air ejector pipes 9 are communicated with the main pipeline 8 through a pressure release valve (not shown in the figure), and the air outlet ends of the air ejector pipes 9 extend into the discharge section 102 and are used for blowing air into the discharge section 102.
As shown in fig. 5 and 6, specifically, in the working process of the pulverized coal bin according to the embodiment of the application, since the vibrating plate 4 reciprocates along the axial direction of the vibrating rod 2 in the vibrating process, the vibrating plate 4 drives the inflating rod 702 to reciprocate, and the inflator 7 inflates the main pipeline 8 through the one-way valve. When the gas pressure in the main pipeline 8 reaches the preset pressure value of the pressure relief valve, the pressure relief valve is opened, and the high-pressure gas stored in the main pipeline 8 is sprayed into the discharging section 102 through the air spraying pipe 9, so that the coal dust can be prevented from being attached to the inner wall of the bin of the discharging section 102, or the coal dust attached to the inner wall of the bin of the discharging section 102 is prevented from being blown off, the coal dust is prevented from being attached to the inner wall of the bin of the discharging section 102 for a long time to be hardened, the cross section area of the discharging section 102 is prevented from being reduced due to the hardening on the inner wall of the bin of the discharging section 102, and the coal dust is prevented from forming arched shed materials to be blocked, so that the anti-blocking effect of the coal dust bin of the embodiment of the application is further improved.
Alternatively, the main pipe 8 is made of rubber material.
When the inflator 7 inflates the main pipeline 8 to a certain extent, the main pipeline 8 can expand due to the fact that the main pipeline 8 is made of rubber materials, more high-pressure gas can be stored in the main pipeline 8, when the main pipeline 8 expands to a certain extent to reach the preset pressure of the pressure relief valve, the pressure relief valve is opened, and the main pipeline 8 blows into the discharging section 102, so that the blowing time is improved, and the blowing effect is good.
Alternatively, the outlet ends of the gas lances 9 are arranged obliquely upwards and the angle between the gas lances 9 and the horizontal plane is 25 ° -35 °.
For example, as shown in fig. 3, 5 and 8, the angle between the gas lance 9 and the horizontal plane may be 25 °, 30 ° or 35 °. The included angle between the air jet pipe 9 and the horizontal plane is 25 degrees to 35 degrees, so that pulverized coal blown up in the discharge section 102 can fly upwards, and the flying pulverized coal can be effectively turned up and down, so that the flowing effect of the pulverized coal in the discharge section 102 is improved, and the blocking of the discharge section 102 is further prevented.

The rotating shaft 11 is rotatably connected with the vibrating plate 4, and the first gear 12 is connected with the rotating shaft 11 through a one-way bearing, so that the first gear 12 drives the rotating shaft 11 to rotate in one direction. The first rack 13 is arranged on the inner wall of the bin of the discharging section 102 and is meshed with the first gear 12, the first rack 13 can drive the first gear 12 to rotate under the vibration action of the vibration plate 4, and the rotating shaft 11 is connected with the scraping plate 10 through the crank rocker mechanism 14 so as to drive the scraping plate 10 to reciprocate in the length direction of the vibration plate 4.
