Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Example 1: Reference Figure 1-4The coal gangue sorting device shown includes a fixed frame 1 and a motor 2. The fixed frame 1 serves as the basic framework of the entire device, supporting and protecting the internal components. A filter plate 16 is hinged to its inner wall side. The filter plate 16 performs preliminary screening of the coal gangue, allowing coal gangue meeting certain particle size requirements to pass through, while larger particles remain above the filter plate 16, achieving preliminary separation of coarse and fine particles and improving sorting efficiency and accuracy. The motor 2 provides power for the operation of the device, and its output end passes through the fixed frame 1. The output end of the motor 2 is fixedly connected to... A deflector rod 20 is connected, and the rotation of the deflector rod 20 can drive a pair of top blocks 21 fixedly connected to the outside to move. The top blocks 21 can intermittently contact the filter plate 16, and generate vibration by pushing the filter plate 16, preventing coal gangue from clogging the screen holes of the filter plate 16 and ensuring the continuous and smooth progress of the screening process. A baffle 15 is provided on the outside of the filter plate 16. The baffle 15 can prevent coal gangue from sliding off the edge of the filter plate 16 during the screening process, ensuring that the screening is carried out within the predetermined area, avoiding material scattering and waste, and improving the accuracy and stability of the sorting. A feed frame 14 is fixedly connected to the inner wall of the fixed frame 1. The feed frame 14 provides a dedicated channel for coal gangue to enter the fixed frame 1, facilitating control of the feed position and direction, so that the coal gangue can accurately fall onto the filter plate 16 for screening. A filter chamber 5 is fixedly connected to the side of the fixed frame 1. The filter chamber 5 is used for further processing and screening of the coal gangue that has undergone preliminary screening. A secondary screening component is set inside the filter chamber 5. The secondary screening component includes a rotating rod 9 that is rotatably connected to the inner wall of the filter chamber 5. The rotating rod 9 can rotate stably inside the filter chamber 5, providing support and power transmission for the movement of subsequent components. Multiple stirring rods 10 are fixedly connected to the outer side of the rotating rod 9. The stirring rods 10 stir the coal gangue entering the filter chamber 5 as the rotating rod 9 rotates, making the coal gangue more evenly distributed inside the filter chamber 5, avoiding coal gangue accumulation in one place, ensuring the comprehensiveness and accuracy of the subsequent screening process, preventing some coal gangue from not being fully screened due to material accumulation, and improving the effect and quality of secondary screening.An arc-shaped filter plate 12 is fixedly connected to the inner wall of the filter chamber 5. The arc-shaped filter plate 12 can further screen the stirred coal gangue. Due to its arc-shaped design, during the flow of coal gangue in the filter chamber 5, smaller coal gangue particles will pass through the screen holes of the arc-shaped filter plate 12 and enter the next process or collection area, further improving the accuracy of coal gangue sorting and separating coal gangue of different particle sizes more finely. A material-pushing plate 11 adapted to the arc-shaped filter plate 12 is fixedly connected to the outer side of the rotating rod 9. During the rotation, the material-pushing plate 11 can promptly dislodge the coal gangue adhering to the arc-shaped filter plate 12, preventing the coal gangue from clogging the screen holes of the arc-shaped filter plate 12 and ensuring... The arc-shaped filter plate 12 ensures efficient screening, enabling the secondary screening process to continue efficiently, thereby improving the overall working efficiency and sorting quality of the coal gangue sorting device. A first feed inlet 7, which is adapted to the feed frame 14, is provided on the outside of the fixed frame 1. The first feed inlet 7 provides an entrance for coal gangue to enter the feed frame 14, facilitating the accurate delivery of coal gangue into the device for sorting, ensuring a smooth start to the entire sorting process. A second feed inlet 8, which is connected to the first feed inlet 7, is provided on the outside of the filter chamber 5. The second feed inlet 8 allows the coal gangue after preliminary screening to smoothly enter the filter chamber 5 from the fixed frame 1 for secondary screening.

[0027] In this embodiment, the material is introduced into the fixed frame 1, and the filter plate 16 filters the material. Small pieces of material fall into the bottom frame 17. The control motor 2 drives the deflection rod 20 and the top block 21 to rotate, lifting the filter plate 16. As the deflection rod 20 continues to rotate, the filter plate 16 will reset under the action of gravity, realizing the reciprocating motion of the filter plate 16, which improves the filtration effect of the material. After the initial filtration of the material is completed, the bolt 19 is unscrewed and the baffle 15 is removed to remove the obstruction of large pieces of material. Large pieces of material fall into the feed frame 14 and fall into the arc-shaped filter plate 12 through the first feed port 7 and the second feed port 8. The control motor 22 drives the rotating rod 9 to rotate, and the rotating rod 9 drives multiple stirring rods 10 to stir the large pieces of material. Small pieces of material wrapped in the large pieces of material fall into the guide frame 13. Finally, the rotating rod 9 drives the material-pushing plate 11 to deflect, pushing the material out of the discharge port 6 and collecting the large pieces of material.

[0028] Example 2: Reference Figure 1-4Based on the same concept as in Embodiment 1 above, this embodiment also proposes that an installation frame 18 is fixedly connected to the outer side of the filter plate 16. The installation frame 18 not only provides a stable installation position for the baffle 15, but its top and bottom are also connected to facilitate the entry and exit of materials. The baffle 15 set inside the installation frame 18 can block and adjust the flow direction of materials. Through the cooperation of the bolts 19 set on the outer side and the threaded holes opened on the inner side of the installation frame 18, it is easy to block large pieces of materials and achieve more thorough filtration of large pieces of materials. The filter chamber 5 has a discharge port 6 on the outer side, which is the channel for the filtered materials to be discharged, ensuring the smoothness of the filtration process. The guide frame 13 fixedly connected to the bottom of the filter chamber 5 can effectively guide the filtered materials to be discharged in a concentrated manner, avoiding the accumulation of materials at the bottom of the chamber and ensuring the continuous and efficient operation of the filtration work; the outer side of the fixed frame 1 The fixed frame 3 provides a stable support structure for the motor 2, enabling the motor 2 to operate smoothly after being fixedly connected to the inner wall of the fixed frame 3, ensuring stable power output. The bottom frame 17, which is fixedly connected to the bottom of the fixed frame 1, helps to collect and guide materials that may leak or overflow from the filter chamber 5, preventing materials from scattering and facilitating subsequent cleaning and secondary processing of materials. The positioning frame 4, which is fixedly connected to the outside of the filter chamber 5, provides the motor 22 with precise positioning and a solid installation foundation. The output end of the motor 22 passes through the filter chamber 5 and is fixedly connected to the rotating rod 9. The motor 22 serves as a power source, driving the rotating rod 9 to rotate, thereby driving the relevant components in the filter chamber 5 to operate, realizing the stirring, turning and other operations of materials, promoting the filtration process, improving the filtration effect and speed, and ensuring that the materials in the filter chamber 5 can be fully and effectively filtered.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
