[0028] Embodiment

[0029] Referring to Figures 1 - 4 , the present utility model provides a bin - type coal - dropping hopper, including a main body 100 of the coal - dropping hopper and at least one bin and hopper 200. The bin and hopper 200 is arranged on the main body 100 of the coal - dropping hopper and is in communication with the main body 100 of the coal - dropping hopper;

[0030] At least one air energy flow-aiding device 600 is provided on the coal dropping hopper main body 100, and each bin and hopper 200 is at least matched with one air energy flow-aiding device 600. The air energy flow-aiding device 600 is used to impact the coal above the bin and hopper 200.

[0031] In some embodiments, one or more bins and hoppers 200 are provided on the coal dropping hopper main body 100 of the bin-type coal dropping hopper. Generally, each bin and hopper 200 is matched with one air energy flow-aiding device 600. The air energy flow-aiding device 600 can be an air cannon. By using the air energy flow-aiding device 600 to inject high-pressure gas into the coal dropping hopper main body 100, the high-pressure gas impacts the coal, dispersing the coal, which can ensure the fluidity of the coal and enable the coal to smoothly flow into the bin and hopper 200, ensuring the coal transportation efficiency.

[0032] Generally, the diameters of the coal dropping hopper main body 100 and the bin and hopper 200 gradually decrease or remain unchanged from top to bottom, which is beneficial to gathering and discharging the coal and ensuring the continuous flow of the coal.

[0033] Refer to Figure 1 , in an alternative embodiment, at least one air energy flow-aiding device 600 is symmetrically provided on the left and right sides of the bin and hopper 200, and the flow directions of the airflows discharged by the two symmetrically provided air energy flow-aiding devices 600 intersect.

[0034] Generally, at least one air energy flow-aiding device 600 is provided on both the left and right sides of the bin and hopper 200, and the airflows discharged by the two symmetrically provided air energy flow-aiding devices 600 can intersect. In this way, the two air energy flow-aiding devices 600 can act on the same part of the coal, improving the impact effect on the coal, making the coal easier to be vibrated and dispersed, and improving the fluidity of the coal; ensuring that the coal can smoothly flow into the bin and hopper 200 and ensuring the coal transportation efficiency.

[0035] In an alternative embodiment, the flow direction of the airflow of the air energy flow-aiding device 600 is downwardly inclined.

[0036] Refer to Figure 4 , in an alternative embodiment, the air energy flow-aiding device 600 includes a flow-aiding device main body 601 and an exhaust pipe 602.

[0037] In some embodiments, the flow assistance device main body 601 of the pneumatic energy flow assistance device 600 is arranged outside the coal dropping hopper main body 100. The flow assistance device main body 601 discharges air flow into the coal dropping hopper main body 100 through an exhaust pipe 602, and the outlet of the exhaust pipe 602 is inclined downward. In this way, the air flow discharged from the exhaust pipe 602 discharges downward obliquely, so that the coal on the upper part of the hopper cavity 700 of the bin and hopper 200 is scattered, and the coal flows more smoothly. Moreover, the air flow discharges downward, reducing the straight-line distance of the air flow and extending the moving range of the air flow in the vertical direction. This is more conducive to the impact on the coal in and above the hopper cavity 700, dispersing the coal and ensuring the fluidity of the coal and the efficiency of coal transportation.

[0038] Generally, a connecting pipe is penetrated through the coal dropping hopper main body 100, and the exhaust pipe 602 is connected to the connecting pipe in a detachable manner. In this way, when it is necessary to replace or repair the pneumatic energy flow assistance device 600, the entire pneumatic energy flow assistance device 600 can be conveniently disassembled.

[0039] In an alternative embodiment, at least one connecting plate 603 is arranged on the flow assistance device main body 601, and the flow assistance device main body 601 is connected to the coal dropping hopper main body 100 through the connecting plate 603.

[0040] In an alternative embodiment, two connecting plates 603 are arranged on the flow assistance device main body 601, and the two connecting plates 603 are arranged in sequence along the height direction.

One end of the connecting plate 603 is connected to the coal dropping hopper main body 100, and the other end is connected to the flow assistance device main body 601. In order to ensure that the flow assistance device main body 601 is more firmly fixed on the coal dropping hopper main body 100, generally two connecting plates 603 are arranged on the flow assistance device main body 601. Generally, one end of the connecting plate 603 is welded to the coal dropping hopper main body 100 or the flow assistance device main body 601, and the other end of the connecting plate 603 is detachably connected to the flow assistance device main body 601 or the coal dropping hopper main body 100.

[0042] In an alternative embodiment, a pneumatic energy flow assistance device 600 is respectively arranged on the left and right sides of the bin and hopper 200, and the flow directions of the air flows discharged by the two pneumatic energy flow assistance devices 600 intersect.

[0043] In an alternative embodiment, a first blanking pipe 400 is arranged at the lower end of the coal dropping hopper main body 100, a second blanking pipe 300 is arranged at the lower end of the bin and hopper 200, and the lower end of the first blanking pipe 400 is lower than the lower end of the second blanking pipe 300.

[0044] Refer to Figure 2, in an alternative embodiment, the coal dropping hopper body 100 has a coal dropping cavity 800, and the bin and hopper 200 has a hopper cavity 700; and the coal dropping cavity 800 communicates with the hopper cavity 700.

[0045] In an alternative embodiment, gate valves 500 are provided on both the coal dropping hopper body 100 and the bin and hopper 200.

[0047] The coal dropping hopper body 100 has a coal dropping cavity 800, and the bin and hopper 200 has a hopper cavity 700. Among them, the hopper cavity 700 communicates with the coal dropping cavity 800. The feed inlet of the hopper cavity 700 is generally located at the middle position of the coal dropping cavity 800, and the coal in the coal dropping cavity 800 can enter the hopper cavity 700 from the feed inlet.

[0048] At least one bin and hopper 200 is provided on the coal dropping hopper body 100 of the bin - type coal dropping hopper provided by the present utility model. When the coal in the coal dropping hopper body 100 cannot smoothly flow into the bin and hopper 200, the air - energy flow - assisting device 600 can emit airflows to impact the coal in the coal dropping hopper body 100, so that the agglomerated coal can be dispersed, thereby improving the fluidity of the coal and ensuring the transportation efficiency of the coal.
