[0030] Next, the technical solutions of this application will be clearly and completely described in conjunction with the drawings.

[0031] Refer to Figures 1 - 5 , the utility model provides a bunker coal hopper, which includes a bunker coal hopper main body 100 and at least one bunker sub-hopper 200. The bunker sub-hopper 200 is arranged on the bunker coal hopper main body 100 and communicates with the bunker coal hopper main body 100;

[0032] An inlet is arranged at the connection between the bunker sub-hopper 200 and the bunker coal hopper main body 100; a rotary feeding assembly 600 is arranged in the bunker coal hopper main body 100, and the rotary feeding assembly 600 is used to move the coal in the bunker coal hopper main body 100 to the inlet.

[0033] In some embodiments, the bunker coal hopper has one bunker coal hopper main body 100 and one or more bunker sub-hoppers 200. The coal in the bunker coal hopper main body 100 can flow out from the hopper opening of the bunker coal hopper main body 100, or can also flow out from the hopper openings of the bunker sub-hoppers 200 at the same time.

[0034] A rotary feeding assembly 600 is arranged inside the bunker coal hopper main body 100. Generally, the volume of the bunker coal hopper main body 100 is larger than that of the bunker sub-hopper 200. The coal in the bunker coal hopper main body 100 needs to flow out from the hopper openings of the bunker coal hopper main body 100 and the bunker sub-hopper 200 under the condition of gravity; the coal flowing out from the hopper openings falls on the receiving belt to realize the transportation of the coal.

[0035] In order to prevent the coal in the bunker coal hopper main body 100 from not flowing downward and affecting the transportation efficiency, a rotary feeding assembly 600 is arranged in the bunker coal hopper main body 100. The rotary feeding assembly 600 can move the coal in the bunker coal hopper main body 100 within a large range, so that the coal in the bunker coal hopper main body 100 will not be caked or will not stop flowing downward due to coal caking; in this way, the fluidity of the coal in the bunker coal hopper main body 100 is ensured.

[0036] And the rotary feeding assembly 600 moves the coal in the bunker coal hopper main body 100 into the bunker sub-hopper 200, ensuring the fluidity of the coal in the bunker sub-hopper 200 and guaranteeing the transportation efficiency.

[0037] In an alternative embodiment, the rotary feeding assembly 600 includes a driving motor 601 and a rotating wheel. The driving motor 601 is arranged outside the bunker coal hopper main body 100, the rotating wheel is arranged inside the bunker coal hopper main body 100, and the driving motor 601 is connected to the rotating wheel through a driving shaft.

[0038] In some embodiments, the driving motor 601 of the rotary feeding assembly 600 is generally disposed outside the main body 100 of the bunker coal hopper. The driving motor 601 is connected to a rotary wheel inside the main body 100 of the bunker coal hopper through a driving shaft, so as to drive the rotation of the rotary wheel.

[0039] In an alternative embodiment, the rotary wheel includes a mounting shaft 603 and a plurality of rotary blades 602. The plurality of rotary blades 602 are uniformly arranged along the circumferential side of the mounting shaft 603.

[0040] The mounting shaft 603 is used to be assembled on the driving shaft of the driving motor 601.

[0041] In an alternative embodiment, the rotary blade 602 has a first major surface and a second major surface. The first major surface is used to push the coal, and reinforcing ribs 6021 are arranged on the second major surface.

[0042] Generally, a plurality of rotary blades 602 are arranged on the mounting shaft 603 of the rotary wheel. In order to ensure the strength of the rotary blades 602, reinforcing ribs 6021 are arranged on the rotary blades 602.

[0043] When the rotary wheel rotates, the first major surface is used to push the coal to move, and the first major surface pushes the coal towards the bunker 200.

[0044] In an alternative embodiment, the height of the rotary blade 602 gradually decreases in the direction away from the mounting shaft 603, and the lower end surfaces of the rotary blades 602 are flush.

[0045] In an alternative embodiment, the first major surface of the rotary blade 602 is a concave arc surface; and the straight line from the upper end to the lower end of the rotary blade 602 inclines forward.

[0046] In order to make the coal more easily enter into the bunker 200, the lower end surfaces of the rotary blades 602 are flush, and the upper end surfaces gradually decrease in the direction away from the mounting shaft 603; in this way, the rotary blades 602 can move more coal towards the bunker 200, improve the fluidity of the coal in the bunker 200, and ensure the efficiency of coal transportation.

[0047] Refer to Figure 2 , in an alternative embodiment, a rotary groove 300 is arranged inside the main body 100 of the bunker coal hopper, and the rotary groove 300 is communicated with the hopper cavity 500 of the bunker 200.

[0048] The main body 100 of the bunker coal hopper has a coal hopper cavity 400, and the mounting shaft 603 is arranged between the hopper cavity 500 and the coal hopper cavity 400.

[0049] In an alternative embodiment, the main bin coal hopper body 100 and the bin dividing hopper 200 are both arranged in the vertical direction, and the hopper openings of the main bin coal hopper body 100 and the bin dividing hopper 200 are both arranged at the lowermost end.

[0050] In some embodiments, a rotating groove 300 is provided in the main bin coal hopper body 100. Some of the rotating wheels are located within the rotating groove 300, that is, some of the rotating wheels are located within the coal hopper cavity 400 of the main bin coal hopper body 100, and some of the rotating wheels are located within the bin dividing hopper 200. When the rotating wheels rotate, the rotating wheels push the coal in the main bin coal hopper into the rotating groove 300 and then into the bin dividing hopper 200. This is conducive to the coal entering the bin dividing hopper 200, ensuring that there is coal entering the bin dividing hopper 200 and guaranteeing the conveying efficiency.

[0051] In order to further improve the efficiency of the rotating wheels in pushing the coal, the first large surface of the rotating blade 602 is a concave arc surface, which can more effectively push the movement of the coal. And in order to make it easier for the coal to enter the bin dividing hopper 200, the connecting line from the lower end to the upper end of the rotating blade 602 forms an acute angle with the horizontal plane. In this way, the rotating blade 602 makes the coal tend to move downward. When the rotating blade 602 moves to the feed inlet of the bin dividing hopper 200, the coal can more easily enter the hopper cavity 500.

[0052] In an alternative embodiment, the rotating feeding assembly 600 further has a transmission assembly, and the driving motor 601 is connected to the rotating wheel through the transmission assembly.

[0053] In an alternative embodiment, two bin dividing hoppers 200 are provided on the main bin coal hopper body 100.

[0054] In some embodiments, the rotating feeding assembly 600 further has a transmission assembly, and the driving motor 601 is connected to the rotating wheel through the transmission assembly; the transmission assembly can enable the drive shaft and the rotating wheel to be arranged at a right angle; the transmission assembly can be a cross steering gear.

[0055] The main bin coal hopper body 100 of the bin coal hopper provided by the present utility model is provided with one or more bin dividing hoppers 200. A rotating feeding assembly 600 is provided in the main bin coal hopper body 100. The rotating feeding assembly 600 can move the coal in the main bin coal hopper body 100 towards the feed inlet of the bin dividing hopper 200, thereby destroying the agglomeration of the coal in the main bin coal hopper body 100, enabling the coal to flow more smoothly under the action of gravity, and guaranteeing the efficiency of coal conveying.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
