Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1 to 6 This utility model provides a technical solution: a coal tower feeding device, including a box body 1, with a feed inlet 2 and a second discharge inlet 16 respectively provided at the top and bottom of the box body 1, and a first discharge inlet 13 opened at the lower end of one side of the box body 1. Multiple transport rollers 17 are equidistantly arranged inside the box body 1 and rotatably connected thereto. There are three transport rollers 17 and a second rotating shaft 20 is coaxially connected to them. The second rotating shaft 20 located in the middle position is rotatably connected to the box body 1 and its end is connected to a first motor 7.

[0024] like Figure 1 , 2As shown, two strip-shaped channels 8 are opened on the side wall of the box body 1. The second rotating shaft 20 at the end is slidably connected in the strip-shaped channel 8. The end of the second rotating shaft 20 is fixedly connected to the first pulley 4. The adjacent first pulleys 4 are connected by a belt. Each of the second rotating shafts 20 at the end is connected to a connecting frame 6. A connecting seat 3 is connected to the side wall of the box body 1. The connecting seat 3 is located between the two connecting frames 6. An electric telescopic rod 5 is connected between the connecting frame 6 and the connecting seat 3. The electric telescopic rod 5 pushes the second rotating shafts 20 on both sides to slide along the strip-shaped channel 8, so that the gap between adjacent conveying rollers 17 can be finely adjusted, so as to meet the conveying and screening of materials with different particle sizes and improve the practicality of processing.

[0025] like Figure 3 As shown, multiple screening rollers are equidistantly arranged on one side of the conveyor roller 17. The conveyor roller 17 and the screening rollers are on the same plane and extend downward at an inclination. The screening roller at the bottom extends to the first discharge port 13. The screening roller includes multiple first rotating shafts 11 that are rotatably connected to the box body 1. One end of the first rotating shaft 11 extends outside the box body 1 and is driven by the second motor 9. A second pulley 10 is fixedly connected to the end of the first rotating shaft 11 that extends outside the box body 1. Adjacent second pulleys 10 are connected by belts. The second motor 9 is connected to the first rotating shaft 11 located at one end. The second motor 9 drives the first rotating shaft 11 to rotate. Under the cooperation of the second pulley 10 and the belt, multiple first rotating shafts 11 can rotate synchronously.

[0026] like Figure 4 , 5 As shown in Figure 6, end plates 22 are symmetrically connected to the first rotating shaft 11 and are coaxially arranged therewith. Multiple second horizontal plates 25 are equidistantly connected between the end plates 22 along the circumference. Second annular seats 15 are rotatably connected to the outer wall of each end plate 22. Multiple first horizontal plates 18 are equidistantly connected between the two second annular seats 15 along the circumference. The number of first horizontal plates 18 and second horizontal plates 25 are equal and the width is the same. The first horizontal plates 18 and second horizontal plates 25 rotate with each other. Due to the staggered placement of the first horizontal plates 18 and second horizontal plates 25, the size of the opening formed between them can be adjusted, so that it can be used for screening materials of different particle sizes.

[0027] To facilitate the user's rotational adjustment of the first horizontal plate 18 and the second horizontal plate 25, the second annular seat 15 is fastened to the end plate 22 with bolts 21, which facilitates fixing and disassembly and allows for rotational adjustment of the second annular seat 15, improving the practicality of the device. One side of the end plate 22 is set as a stepped structure, and the second annular seat 15 is rotatably connected to the end plate 22 through bearings 24, which improves the stability of the connection between the two. An annular plate 19 is coaxially connected to one side of the second annular seat 15. The annular plate 19 is coaxially set with the outer wall of the end plate 22, and bolts 21 are used to lock the annular plate 19 and the end plate 22, further improving the stability of the connection between the end plate 22 and the second annular seat 15.

[0028] like Figure 5 As shown, in order to further ensure the stable rotation of the first horizontal plate 18 and the second horizontal plate 25, a positioning plate 26 connected to the first rotating shaft 11 is coaxially arranged between the two end plates 22. The second horizontal plate 25 is fastened to the positioning plate 26, and a first annular seat 14 is coaxially arranged on the outside of the positioning plate 26. The inner wall of the first annular seat 14 is clearance-fitted with the outer wall of the second horizontal plate 25, and the first horizontal plate 18 is fastened to the first annular seat 14. When the first horizontal plate 18 rotates on the outer wall of the second horizontal plate 25, the first annular seat 14 rotates synchronously outside the positioning plate 26. This not only ensures stable rotation adjustment, but also improves the overall stability of the first horizontal plate 18 and the second horizontal plate 25, preventing the first horizontal plate 18 and the second horizontal plate 25 from being bent by the impact of falling coal due to their excessive length, thereby ensuring normal screening.

[0029] In summary, in order to ensure the collection of large-diameter coal particles after screening, a guide seat 12 is connected to the side of the box 1 near the first discharge port 13 during use of this coal tower feeding device. The top of the guide seat 12 extends to the screening roller at the bottom, and the bottom of the guide seat 12 is connected to the first discharge port 13. A collection device is also connected to the first discharge port 13. At the same time, in order to facilitate the rapid falling of coal materials, a downward-extending inclined plate 23 is connected to the inner wall of the box 1. The bottom of the inclined plate 23 extends to the conveying roller 17 at the top, and multiple vibrating motors are installed at the bottom of the inclined plate 23 to further improve the falling efficiency of materials and improve the processing efficiency.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
