[0036] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0037] See also Figure 1-Figure 3 This embodiment provides a flow dividing device, comprising: a frame 10 and two rows of roller assemblies 20 arranged on the frame 10; wherein the frame 10 has a flow dividing starting end; wherein the flow dividing starting end is Figure 3 The position indicated by A in Figure 3 It can be seen from the figure that the flow diversion device is in a "V" shape as a whole. The two rows of roller assemblies 20 are arranged in two rows from the position close to the diversion starting end, and the angle between the two rows of roller assemblies 20 is an acute angle. The roller assemblies 20 are used to guide the diverted materials and gradually arrange the diverted materials in rows from the diversion starting end. Figure 7 and Figure 8 , which shows a schematic diagram of a diverting device being arranged on a conveyor belt to perform diverting work. In this embodiment, the diverted object is coal 70 with coal gangue. The diverting device is arranged on a bracket 60, and the bottom of the diverting device is arranged to be flush with the conveyor belt 50. The bracket 60 is fixed relative to the conveyor belt 50. When the conveyor belt 50 drives the coal 70 with coal gangue to move, the diverting device divides the coal 70 with coal gangue into two columns, so that the coal 70 with coal gangue can be more easily identified and sorted. Since the roller assembly 20 can roll and rub against the coal 70 with coal gangue, the wear of the roller assembly 20 is reduced.

[0038] The larger the angle between the two rows of roller assemblies 20, the larger the distance between the two rows of separated diverted objects. At the same time, the diverter receives greater resistance and wear. Those skilled in the art can design the specific value of the angle between the two rows of roller assemblies 20 according to needs.

[0039] Combined with reference Figure 4 In a specific embodiment, the frame 10 includes an upper cover plate 11, a lower cover plate 12 and a connecting block 13, and the two ends of the connecting block 13 are respectively connected to the upper cover plate 11 and the lower cover plate 12; the two rows of roller assemblies 20 are arranged between the upper cover plate 11 and the lower cover plate 12. The upper cover plate 11 and the lower cover plate 12 can protect the two rows of roller assemblies 20, prevent fine coal slag from entering the narrow gap of the roller assemblies 20, and reduce the problem of the roller assemblies 20 being stuck.

[0040] In the above embodiment, the connection block 13 is located at the diversion starting end of the frame 10 and has two diversion surfaces 131. The angle between the two diversion surfaces 131 is an acute angle, and one end of the two rows of roller assemblies 20 is against the connection block 13. In addition to connecting the upper cover plate 11 and the lower cover plate 12, the connection block 13 also plays an initial diversion role for the diverted material. The angle between the diversion surfaces 131 can be equal to the angle between the two rows of roller assemblies 20, or it can be unequal.

[0041] Furthermore, in order to reduce the impact of the diverted objects on the connecting block 13, a first diverter roller 30 is provided at the diverting start end of the frame 10, and the two ends of the first diverter roller 30 are respectively provided on the upper cover plate 11 and the lower cover plate 12, and can rotate relative to the frame 10; the intersection of the two diverter surfaces 131 is located on the cross section of the first diverter roller 30. Through the above arrangement, after the diverted objects hit the first diverter roller 30, they can flow to the side of the diverter surface 131 under the rotation of the first diverter roller 30, thereby improving the diverting effect.

[0042] Furthermore, the frame 10 also includes a support shaft 14 for supporting the upper cover plate 11 and the lower cover plate 12, and the support shaft 14 is arranged between the two roller assemblies 20, and one end of the support shaft 14 is connected to the upper cover plate 11, and the other end is connected to the lower cover plate 12. The support shaft 14 can make the structure of the frame 10 more stable. A plurality of support shafts 14 can be provided according to the length of the upper cover plate 11 and the lower cover plate 12. In the present embodiment, two support shafts 14 are provided, and the position of one of the support shafts 14 is arranged at the end of the upper cover plate 11 and the lower cover plate 12 as far as possible, and away from the connecting block 13. If a plurality of support shafts 14 are provided, the distances between the plurality of support shafts 14 should be arranged as evenly as possible.

[0043] Combined with reference Figure 5 Each of the roller assemblies 20 includes: a swing frame 21 and a plurality of second diverter rollers 22 disposed on the swing frame 21, and the second diverter rollers 22 can rotate relative to the swing frame 21; the plurality of second diverter rollers 22 are arranged in parallel in sequence and are located in the same plane, and one end of the two swing frames 21 is hinged to the frame 10, so that the two roller assemblies 20 can rotate relative to the frame 10. Through the above scheme, since the swing frame 21 is hinged to the frame 10, it is achieved that the roller assemblies 20 can rotate relative to the frame 10, so that the angle between the two roller assemblies 20 can be more conveniently adjusted.

[0044] Specifically, the swing frame 21 includes an upper swing plate 211, a rotating shaft 212 and a lower swing plate 213, the upper swing plate 211, the rotating shaft 212 and the lower swing plate 213 are fixedly connected in sequence to form a "U"-shaped structure, and the two ends of each second diverter roller 22 are respectively hinged to the upper swing plate 211 and the lower swing plate 213, and can rotate relative to the swing frame 21, and the rotating shaft 212 is hinged to the frame body 10. Of course, the swing frame 21 can also be replaced with other structural forms according to design requirements, which will not be described in detail here.

[0045] In order to adjust the angle between the two roller assemblies 20, an angle adjustment assembly 40 is provided between the two roller assemblies 20 for adjusting the angle between the two roller assemblies 20. The angle adjustment assembly 40 may be of any structural form as long as it can adjust the angle between the two roller assemblies 20. In this embodiment, the angle adjustment assembly 40 adopts the following structure:

[0046] See also Figure 6 The angle adjustment assembly 40 includes a first connecting plate 41, a second connecting plate 42 and a connecting shaft 43; the first connecting plate 41 and the second connecting plate 42 are respectively hinged to the two roller assemblies 20, and the first connecting plate 41 and the second connecting plate 42 are hinged together through the connecting shaft 43, and the end of the connecting shaft 43 is arranged on the frame 10 so that the connecting shaft 43 is radially constrained. The roller assembly 20 is provided with a hinge shaft 23, and the first connecting plate 41 and the second connecting plate 42 are both hinged to the roller assembly 20 through the corresponding hinge shaft 23.

[0047] In a preferred embodiment, the first connecting plate 41 is provided with a plurality of first circular holes 411 for cooperating with the connecting shaft 43, and the plurality of first circular holes 411 are arranged along the length direction of the first connecting plate 41; the second connecting plate 42 is provided with a plurality of second circular holes 421 for cooperating with the connecting shaft 43, and the plurality of second circular holes 421 are arranged along the length direction of the second connecting plate 42. The connecting shaft 43 can adjust the angle between the two roller assemblies 20 by changing different first circular holes 411 and second circular holes 421. This arrangement is simple in structure and convenient to adjust.
