[0031] On the basis of the above embodiments, further, in a preferred embodiment of the present invention, the diverter mechanism 200 includes a diverter plate 201 and a fixed leg 202; the diverter plate 201 is connected to the inner wall of the silo body 100 through the fixed leg 202, and the diverter plate 201 is provided with a pointed end, and the pointed end of the diverter plate 201 faces the side away from the material outlet 101, and a discharge channel is formed between the two ends of the diverter plate 201 and the inner wall of the silo body 100.

[0032] Optionally, the fixed legs 202 and the diverter plate 201 may be connected in various ways, such as welding, clamping or threaded connection. Preferably, the fixed legs 202 and the diverter plate 201 are connected by welding.

[0033] In a preferred embodiment of the present invention, the silo body 100 is conical, the diverter plate 201 is conical, and the conical direction of the silo body 100 is opposite to the conical direction of the diverter plate 201 .

[0034] In this embodiment, the silo body 100 adopts a conical structure, and the material outlet 101 is arranged at the tip of the silo body 100 with a conical structure.

[0036] Optionally, four fixed legs 202 are provided, and the four fixed legs 202 are evenly arranged at equal intervals in the circumferential direction of the diverter plate 201. Since the fixed legs 202 are provided between the diverter plate 201 and the silo body 100, there is a gap between any two fixed legs 202. When the material falls into the silo body 100 along the conical surface of the diverter plate 201, the material will fall to the material outlet 101 of the silo body 100 through any two adjacent fixed legs 202.

[0037] In a preferred embodiment of the present invention, the swing mechanism 300 includes a swing chain 301 and a guide plate 302; the swing chain 301 is connected to the center of the conical diverter plate 201, and the swing chain 301 is located on the side of the diverter plate 201 facing the material outlet 101, the swing chain 301 is connected to the guide plate 302, and the swing chain 301 can drive the guide plate 302 to swing in the space between the diverter plate 201 and the silo body 100.

The guide plate 302 is vertically downward under the action of gravity, and the guide plate 302 is located between the diverter plate 201 and the silo body 100. When the material enters the silo, it will contact the conical diverter plate 201, and then flow along the conical diverter plate 201 to the silo wall of the silo body 100, and then flow to the material outlet 101. As the material enters, under the action of the diversion of the diverter plate 201, the material contacts the guide plate 302 after contacting the silo wall of the silo body 100. The guide plate 302 swings left and right due to the impact of the material, so that the material evenly covers the upper part of the material outlet 101, and is discharged along the material outlet 101 until the material stops the guide plate 302 from swinging, forming a material-free space between the diverter plate 201 and the material outlet 101.

[0039] In order to ensure the stability of the installation of the swing chain 301, in a preferred embodiment of the present invention, it also includes a connecting plate 303; the connecting plate 303 is located at the center of the conical diverter plate 201, and the connecting plate 303 is connected to the inner wall of the diverter plate 201, so that the cross-sectional shape of the diverter plate 201 and the connecting plate 303 is triangular, and the swing chain 301 is connected to the connecting plate 303.

[0040] Optionally, the connection between the connecting plate 303 and the inner wall of the diverter plate 201 is by welding, and the cross-sectional shape of the connecting plate 303 can be circular or rectangular, and the connection between the connecting plate 303 and the diverter plate 201 only needs to be stable.

[0041] In a preferred embodiment of the present invention, an exhaust mechanism 400 is also included; an air outlet 102 is provided on the inner wall of the silo body 100, and the exhaust mechanism 400 is connected to the air outlet 102. The exhaust mechanism 400 is used to discharge high-pressure gas into the space formed by the diversion mechanism 200 and the silo body 100 through the air outlet 102.

[0042] In this embodiment, an external exhaust mechanism 400 is utilized. When the silo body 100 discharges the material, the exhaust mechanism 400 is opened and the high-pressure gas is discharged into the silo body 100 by using an air cannon to break the arch. Under the action of the gas, the material cannot fit with the inner wall of the silo body 100. The strong airflow generated by the high-pressure gas and the impact energy generated by the rapid expansion of the gas rush into the blocked and retained area of ​​the material, so that the material in the silo body 100 resumes the gravity flow to complete the arch breaking.

[0043] In a preferred embodiment of the present invention, the exhaust mechanism 400 includes an air source 401, a compression pipeline 402 and a control valve 403; the air source 401 is connected to the air outlet 102 through the compression pipeline 402, the air source 401 is used to transport high-pressure gas into the compression pipeline 402, and the control valve 403 is located on the compression pipeline 402.

[0044] Optionally, the control valve 403 may be a solenoid valve, and the gas source 401 may be a compressor, or a high-pressure blower, etc.

[0046] In this embodiment, when the material outlet 101 is opened, the material is discharged normally. Due to the presence of the conical diverter plate 201 and the guide plate 302, the material encounters less resistance during flow and storage, and the fluidity is improved. At this time, the compressed gas is supplied by the gas source 401 through the compression pipe 402, the control valve 403 is opened, and the compressed gas enters the silo body 100 along the compression pipe 402. The one-way air valve 404 is opened, and the strong airflow generated by the sudden ejection of compressed air causes the material adhering to the silo wall of the silo body 100 to fall off and resume gravity flow.

[0047] A material bin provided in this embodiment includes the material bin discharging device described above; since the technical effect of the material bin provided in this embodiment is the same as the technical effect of the material bin discharging device provided in the above embodiment, it will not be described in detail here.
