[0028] As Figures 1-4 shown, a slate grinding machine in an embodiment of this utility model includes a positioning structure 1, a grinding device 2, and a collection box body 3. The grinding device 2 is arranged on both sides of the positioning structure 1; the collection box body 3 is arranged below the positioning structure 1 and communicated with the positioning structure 1. The collection box body 3 is divided into a collection cavity 31, a transfer cavity 32, and a treatment cavity 33.

A slag outlet 14 corresponding to the collection cavity 31 is arranged at the bottom of the support box body 11. A second inclined plate 15 is arranged in the support box body 11, and the second inclined plate 15 is inclined downward from the direction away from the slag outlet 14 towards the direction close to the slag outlet 14, so that the waste slag can naturally slide from the support box body 11 to the slag outlet 14 under the action of gravity, further ensuring the smooth discharge of the waste slag.

[0030] As a preferred embodiment of the present utility model, it may further have the following additional technical features: An extension plate 16 is fixedly connected above the support box body 11, increasing the support area above the support box body 11, thereby enhancing the stability of the entire positioning structure 1, preventing flying objects or waste slag generated during the grinding process from causing harm to the operator, and reducing the flying range of the waste slag.

[0031] As a preferred embodiment of the present utility model, it may further have the following additional technical features: A treatment device 34 and an aggregate box 35 are arranged in the treatment cavity 33. The aggregate box 35 is arranged below the treatment device 34. The treatment device 34 is fixedly connected to the inner wall of the treatment cavity 33, and the aggregate box 35 is detachably connected to the inner wall of the treatment cavity 33. The treatment device 34 is located in the treatment cavity 33 and can further treat the waste slag transported from the transfer cavity 32.

The vibration structure 341, the filtering structure 342, and the crushing structure 343 are respectively fixedly connected to the inner wall of the treatment cavity 33. The vibration structure 341 is arranged below the discharge pipe 322. When the waste slag enters the treatment cavity 33 from the transfer cavity 32 through the discharge pipe 322, it will first come into contact with the vibration structure 341. The vibration structure 341 helps the waste slag flow and disperse better through vibration. The filtering structure 342 is located below the vibration structure 341, and its main function is to preliminarily screen and filter the waste slag. The crushing structure 343 is located below the filtering structure 342, and its main function is to crush the filtered waste slag.

[0033] As a preferred embodiment of the present utility model, it may further have the following additional technical features: The vibration structure 341 includes a limit buffer structure 3411, a vibration frame 3412, and a vibration motor 3413.

The surface of the vibration frame 3412 away from the vibration motor 3413 is fixedly connected to the filtering structure 342. The vibration motor 3413 provides power for the vibration structure 341 to generate vibration; the vibration frame 3412 is a bracket for fixing the vibration motor 3413 and the filtering structure 342; the limit buffer structure 3411 is used to control the amplitude and stability of the vibration.

[0034] As a preferred embodiment of the present utility model, it may further have the following additional technical features: The limit buffer structure 3411 includes a telescopic rod 34111 and an elastic member 34112.

The end of the elastic member 34112 away from the telescopic rod 34111 is fixedly connected to the vibration frame 3412. By providing the telescopic rod 34111 and the elastic member 34112, the telescopic rod 34111 can limit the movement of the vibration frame 3412 when the vibration motor 3413 works to drive the vibration frame 3412 to vibrate, avoiding the situation of the vibration frame 3412 shaking up and down, and ensuring the stable movement of the vibration frame 3412.

[0035] As a preferred embodiment of the present utility model, it may further have the following additional technical features: The filtering structure 342 includes a coarse metal mesh 3421, a fine metal mesh 3422, and a retaining rod 3423. The coarse metal mesh 3421 and the fine metal mesh 3422 are respectively connected to the vibration frame 3412. The coarse metal mesh 3421 and the fine metal mesh 3422 are both inclined downward in the direction away from the vibration frame 3412. The coarse metal mesh 3421 is arranged above the fine metal mesh 3422. Two retaining holes 34231 are formed on the retaining rod 3423. The ends of the coarse metal mesh 3421 and the fine metal mesh 3422 away from the vibration frame 3412 respectively abut against one of the retaining holes 34231. The coarse metal mesh 3421 is mainly used to filter out larger particles and impurities in the waste residue, while the fine metal mesh 3422 can further filter out finer particles and powders, ensuring the hierarchical filtration of the slate waste.

[0036] As a preferred embodiment of the present utility model, it may further have the following additional technical features: The crushing structure 343 includes a crushing motor 3431, a rotating shaft 3432, and a crushing assembly 3433. The crushing motor 3431 is fixedly arranged on the outer wall of the collection box 3. One end of the rotating shaft 3432 is connected to the crushing motor 3431. The end of the rotating shaft 3432 away from the crushing motor 3431 penetrates the collection box 3 and enters the processing cavity 33. Two crushing assemblies 3433 are arranged on the rotating shaft 3432. One of the crushing assemblies 3433 abuts against one end of the coarse metal mesh 3421 away from the vibration frame 3412, and the other crushing assembly 3433 abuts against one end of the fine metal mesh 3422 away from the vibration frame 3412.

[0037] As a preferred embodiment of the present utility model, it may further have the following additional technical features: The crushing assembly 3433 includes a crushing roller 34331, a crushing shell 34332, and a connecting rod 34333. The crushing roller 34331 is fixedly connected to the rotating shaft 3432. One end of the connecting rod 34333 is connected to the retaining rod 3423. The end of the connecting rod 34333 away from the retaining rod 3423 is connected to the crushing shell 34332. The crushing shell 34332 is arranged corresponding to the position of the crushing roller 34331. By arranging the crushing roller 34331 and the crushing shell 34332, the crushing roller 34331 rotates under the drive of the rotating shaft 3432 and contacts the crushing shell 34332 to crush the waste material falling into the crushing shell 34332, ensuring that the crushing process of the waste material can proceed smoothly.

[0038] The working principle of the slab grinding machine in this embodiment is as follows: The waste material ground from the slab falls into the collection cavity 31 from the slag outlet 14. The screw conveyor 321 is started to convey the grinding waste material upward to the discharge pipe 322. At this time, the processed waste material passes through the discharge pipe 322 and falls on the coarse metal mesh 3421 through the vibration frame 3412. At the same time, the vibration motor 3413 starts to work, causing the coarse metal mesh 3421 and the fine metal mesh 3422 to vibrate. At this time, the larger grinding waste material directly falls into the crushing shell 34332. At the same time, the crushing roller 34331 rotates to roll the waste material, so that the rolled waste material continues to fall into the second crushing shell 34332 for continuous rolling. At the same time, the smaller grinding waste material falls onto the fine metal mesh 3422, so that the smaller grinding waste material falls into the second crushing shell 34332 for rolling. The rolled waste material falls into the aggregate box 35. The aggregate box 35 can be pulled out to take out the collected and crushed waste material. At this time, the collection and treatment process of the waste material is completed.

[0039] The structural design of the slab grinding machine in this embodiment is reasonable and convenient to use. For other devices with similar usage requirements, this structure can also be adopted. In this embodiment, through the collection and treatment of slab waste chips and residues, the recyclable parts can be recovered, improving the resource utilization rate and reducing the production cost.
