[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0021] This utility model embodiment provides a coal gangue raw material crushing and grinding device, such as... Figure 1-4 As shown, the coal gangue raw material crushing and grinding device includes: a support frame 1; a vertical grinding mill 2 installed on the support frame 1 for grinding coal gangue; a feed pipe 3 fixed at the feed end of the vertical grinding mill 2 for guiding the addition of coal gangue; a filter box 4 installed on the top of the feed pipe 3 for screening coal gangue raw materials; a support plate 7 fixed on the outer wall of the filter box 4 for receiving large pieces of coal gangue raw materials; a receiving component 19 set on the support frame 1 for receiving spilled large pieces of coal gangue raw materials; a crushing box 10 set on the top of the filter box 4 for breaking large pieces of coal gangue; and a screening structure set inside the filter box 4 for screening coal gangue raw materials.
[0022] In this embodiment, the support frame 1 serves as the foundation for the entire device, ensuring the stable installation and operation of all components. The vertical grinding mill 2 is a key piece of equipment for coal gangue grinding, effectively grinding coal gangue with acceptable particle size after screening to improve product quality. The feed pipe 3 guides the coal gangue raw material into the grinding mill, ensuring that the coal gangue can smoothly and orderly enter the grinding process. The filter box 4, through screening, sends coal gangue with acceptable particle size into the feed pipe 3, while coal gangue with unacceptable particle size remains in the filter box 4 for further processing. The support plate 7 is used to receive large pieces of coal gangue. The receiving part 19 is used to receive large pieces of coal gangue raw material spilled from the filter box 4 or the crushing box 10, preventing coal gangue from scattering and causing environmental pollution. It also facilitates the collection and processing of these large pieces of coal gangue. The crushing box 10 is used to break up large pieces of coal gangue. Through the processing of the crushing box 10, coal gangue that does not meet the particle size standard is crushed into smaller particles so that it can be screened or ground again. This design significantly reduces the need for manual processing of large pieces of coal gangue. Through the fine processing of the screening structure, it can be ensured that only coal gangue that meets the particle size standard enters the grinding mill, improving grinding efficiency and product quality.
[0023] In a further preferred embodiment of the present invention, the screening structure includes a fixing plate 11 fixed on the inner wall of the filter box 4, a spring 12 mounted on the fixing plate 11, a connecting plate 13 fixed on the spring 12, a filter plate 14 fixed on the connecting plate 13 for screening coal gangue raw materials, a power box 16 fixed on the inner wall of the filter box 4, and a camshaft 15 rotatably mounted in the filter box 4 and in contact with the filter plate 14. The power box 16 is provided with a servo motor whose output shaft is connected to the camshaft 15.
[0024] In this embodiment, the screening structure ensures effective screening of coal gangue raw materials through the coordinated work of internal components. The fixing plate 11 is firmly installed on the inner wall of the filter box 4, providing a stable installation base for subsequent components. The spring 12 provides a certain elasticity and buffer for the screening process, ensuring the stability and durability of screening. The connecting plate 13 connects the spring 12 and the filter plate 14, a key component for screening coal gangue raw materials. The filter plate 14 is provided with screen holes for screening coal gangue raw materials according to particle size. When the servo motor is started, it drives the camshaft 15 to rotate, thereby driving the filter plate 14 to reciprocate and vibrate. This vibration helps the coal gangue raw materials to be screened more thoroughly on the filter plate 14. Through the coordinated work of the fixing plate 11, spring 12, connecting plate 13, filter plate 14, power box 16 and camshaft 15, efficient screening of coal gangue raw materials is achieved.
[0025] In a further preferred embodiment of this utility model, the top of the vertical grinding mill 2 is hinged with a support leg 5 and a hydraulic rod 6. The support leg 5 is connected to the bottom of the support plate 7. The output rod of the hydraulic rod 6 is hinged to the support plate 7. A crushing roller is rotatably installed inside the crushing box 10. A reciprocating motor for driving the crushing roller to rotate is installed on the crushing box 10. The output shaft of the reciprocating motor is connected to the crushing roller.
[0026] In this embodiment, the vertical grinding mill 2 is a key piece of equipment for coal gangue grinding. Its top is connected to the support leg 5 and the hydraulic rod 6 by a hinge. This design allows the vertical grinding mill 2 to obtain more stable support during installation and operation. By extending and retracting the hydraulic rod 6, the angle of the support plate 7 can be adjusted to facilitate the pouring out of the large pieces of coal gangue in the support plate 7. The large pieces of coal gangue enter the receiving part 19 and are conveyed by the receiving part 19 and put into the crushing box 10 for crushing. The crushing roller is a key component for crushing large pieces of coal gangue. It can crush coal gangue that does not meet the particle size standard into smaller particles so that it can be screened or ground again.
[0027] In a further preferred embodiment of this utility model, the receiving component 19 comprises a slider 18 slidably mounted on the support frame 1, a support plate 20 fixed on the slider 18, an adjusting plate 21 hinged on the support plate 20, a rubber sheet 22 fixed between the support plate 20 and the adjusting plate 21, a storage space for storing large pieces of coal gangue provided between the support plate 20, the adjusting plate 21 and the rubber sheet 22, a support cylinder 23 fixed on the support plate 20 and the adjusting plate 21, an adjusting ball 24 rotatably mounted in the rotating shaft support cylinder 23, and an electric telescopic rod 25 installed between the two adjusting balls 24 for adjusting the angle between the support plate 20 and the adjusting plate 21.
[0028] In this embodiment, the slider 18 is slidably mounted on the support frame 1, allowing the receiving component 19 to move along the support frame 1 as needed. The support plate 20 provides a stable support base for the receiving component 19. The adjusting plate 21 can rotate at a certain angle relative to the support plate 20. This design allows the receiving component 19 to adjust its opening size as needed. The rubber sheet 22 acts as a buffer and closure mechanism. When large pieces of coal gangue fall onto the receiving component 19, the rubber sheet 22 can absorb some of the impact force, protecting the support plate 20 and the adjusting plate 21 from damage. At the same time, the sealing performance of the rubber sheet 22 can also prevent coal gangue from falling out of the receiving component 19. A storage space is formed between the support plate 20, the adjusting plate 21, and the rubber sheet 22 through the gap. This space is used to store large pieces of coal gangue that have spilled from the filter box 4 or the crushing box 10. The design of this storage space allows the large pieces of coal gangue to be collected in a concentrated manner, which is convenient for subsequent processing or recycling. The adjusting ball 24 is rotatably installed inside the support cylinder 23, which allows the electric telescopic rod 25 to adjust the angle between the support plate 20 and the adjusting plate 21 through telescopic movement. This design allows the receiving part 19 to quickly adjust its opening angle as needed to accommodate large pieces of coal gangue of different sizes or shapes, and to ensure that the coal gangue can fall smoothly into the storage space.
[0029] In a further preferred embodiment of the present invention, a threaded rod 26 is rotatably mounted on the support frame 1, and the slider 18 is threadedly sleeved on the threaded rod 26. A motor box 27 is mounted on the support frame 1, and a stepper motor with an output shaft connected to the threaded rod 26 is provided inside the motor box 27. The stepper motor is used to drive the threaded rod 26 to rotate.
[0030] In this embodiment, the threaded rod 26 serves as a transmission component. Its design allows the slider 18, which is threadedly engaged with it, to move along its axial direction under the rotation of the threaded rod 26. The slider 18 is specifically designed to be threaded onto the threaded rod 26. This engagement ensures the stable movement of the slider 18 when the threaded rod 26 rotates. Stepper motors are known for their precise control and stable operation. They can rotate their output shaft in fixed steps (i.e., angles) according to a preset program or instruction. In this application, the stepper motor drives the rotation of the threaded rod 26, thereby achieving precise control over the position of the slider 18 and its receiving part 19.
[0031] In a further preferred embodiment of this utility model, an adjusting ring 9 for storing large pieces of coal gangue is movably sleeved on the outside of the filter box 4, and a cylinder 8 for adjusting the height of the adjusting ring 9 is fixed on the support plate 7 with an output rod connected to the adjusting ring 9.
[0032] In this embodiment, the adjusting ring 9 is designed to be movably fitted outside the filter box 4, forming an annular space around the filter box 4. This space is used to store large pieces of coal gangue that fail to pass through the filter plate 14. As coal gangue raw materials are continuously fed in and the screening process proceeds, large pieces of coal gangue will gradually accumulate inside the adjusting ring 9. In order to achieve precise adjustment of the height of the adjusting ring 9, a cylinder 8 is fixed on the support plate 7. The output rod of the cylinder 8 is connected to the adjusting ring 9. Through the extension and retraction of the cylinder 8, the adjusting ring 9 can be pushed or pulled up and down, thereby changing the size of its internal storage space. After the adjusting ring 9 moves down, the large pieces of coal gangue stored inside fall onto the support plate 7.
[0033] In a further preferred embodiment of the present invention, the guide tube 3 is made of flexible hose, and an elastic pad 17 that can contact the filter plate 14 for noise reduction is installed on the fixing plate 11. The fixing plate 11 is also used to support the filter plate 14, and a limiting telescopic rod is provided inside the spring 12 for limiting the extension and retraction path of the spring 12.
[0034] In this embodiment, the material of the flexible tube 3 gives it better flexibility and adaptability, allowing it to bend and stretch as needed. The design of the elastic pad 17 reduces direct contact between the filter plate 14 and the fixed plate 11 during vibration, thereby reducing noise pollution. In addition, the elastic pad 17 also provides a certain buffering effect, protecting the filter plate 14 from damage. Meanwhile, the fixed plate 11, as the supporting structure of the filter plate 14, ensures the stability and accuracy of the screening process. The design of the limiting telescopic rod ensures that the spring 12 always moves along a predetermined path during extension and retraction, avoiding equipment damage or performance degradation caused by disordered extension and retraction of the spring 12. This design improves the stability and reliability of the equipment, ensuring the continuity and accuracy of the screening process.
[0035] In summary, compared with related technologies, this device, by integrating a vertical grinding mill 2, a screening structure, a crushing box 10, and a flexible material receiving and adjustment system, achieves efficient and orderly processing of coal gangue raw materials. It not only automatically screens the coal gangue raw materials, ensuring that only materials meeting the particle size standards enter the grinding mill, thereby improving grinding efficiency and product quality, but also automatically crushes large pieces of coal gangue, reducing the need for manual processing. Furthermore, through its flexible material receiving and adjustment design, this device effectively prevents environmental pollution caused by scattered coal gangue and facilitates the collection and processing of large pieces of coal gangue. In addition, it employs noise reduction and buffering designs, improving the stability and reliability of the equipment and ensuring the continuity and accuracy of the screening and grinding processes.
