[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. 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.

[0034] Figure 1 The illustration schematically shows a grinding apparatus for a vibratory mill applicable to an embodiment of the present invention.

[0035] Reference Figures 1-8 As shown, this application provides a grinding apparatus for a vibratory mill, comprising:

[0036] A container 10 is used to hold raw materials; the container 10 is provided with a discharge port 11.

[0037] A bowl cover 20 is used to seal the bowl body 10; the bowl body 10 is covered and sealed to the bowl body 10; the bowl body 10 and the bowl cover 20 together form a grinding cavity;

[0038] A grinding assembly 30 is used to grind the raw material inside the grinding chamber; the grinding assembly 30 is disposed inside the grinding chamber.

[0039] A switch assembly 40 is used to block or open the discharge port 11; the switch assembly 40 is movably connected to the container body 10.

[0040] A sample cup 60 is used to hold an object; the sample cup 60 is movably connected to the switch assembly 40.

[0041] When the switch assembly 40 moves to the first position, it seals the discharge port 11; when it moves to the second position, it opens the discharge port 11. It should be noted that in this application, opening the discharge port 11 can be partial or complete. The size of the discharge opening formed after opening the discharge port 11 is smaller than the size of the connecting cylinder 46, thus preventing the discharge port from being too large and causing the ground material to be discharged from the connecting cylinder 46, resulting in spillage.

[0042] In this embodiment, the bowl cover 20 is placed on the bowl body 10, forming a sealed grinding chamber for holding raw materials. The grinding assembly 30 grinds the raw materials to obtain grinding powder, and the discharge port 11 discharges the grinding powder. During grinding, the switch assembly 40 moves to the first position, at which time the switch assembly 40 seals the discharge port 11, and the raw materials are ground in the sealed grinding chamber. After grinding is completed, the switch assembly 40 moves to the second position, at which time the switch assembly 40 opens the discharge port 11, and the grinding powder is discharged from the discharge port 11. The sample cup 60 is used to hold raw materials or ground samples. The sample cup 60 is movably connected to the switch assembly 40. The opening shape of the sample cup 60 is the same as the lower shape of the connecting cylinder 46 to facilitate movable connection with the connecting cylinder 46.

[0043] In this embodiment, the bowl 10 serves as the container for the raw materials, and its outlet 11 is used to discharge the ground materials. The design of the bowl is fundamental, ensuring a suitable environment for the grinding operation. The bowl cover 20 seals the bowl 10, forming a closed grinding chamber. This design effectively reduces dust leakage during grinding and improves the working environment. The grinding assembly 30 is located within the grinding chamber and is responsible for grinding the raw materials, ensuring effective grinding. The innovation of the switch assembly 40 lies in its dual function—blocking or opening the outlet 11. The switch assembly is movably connected to the bowl, allowing for flexible operation. When the switch assembly is in the first position, it tightly seals the outlet to prevent dust leakage during grinding; when moved to the second position, it opens the outlet, allowing the ground materials to be discharged. This design not only reduces dust but also simplifies the material discharge process. The sample cup 60 is used to hold the raw material discharged from the grinding chamber. The sample cup is movably connected to the switch assembly. When the switch assembly opens the discharge port, the ground raw material can fall directly into the sample cup, which is convenient for collection and avoids dust flying.

[0044] Through the above design, the grinding apparatus of this application achieves the following improvements:

[0045] Dust Reduction: The sealed connection between the bowl and the bowl cover, as well as the sealing and opening control of the discharge port by the switching assembly, effectively reduce the leakage of raw material dust during the grinding process and improve the working environment.

[0046] Simplified operation: The design of the switch component makes it easier to discharge raw materials without manual cleaning, and the direct collection of sample cups also avoids secondary processing of raw materials.

[0047] Improved efficiency: The entire grinding process is more automated and efficient, reducing manual intervention and improving grinding efficiency and safety.

[0048] For example, a tray 12 is provided on the container 10, and the tray 12 is close to the discharge port 11. When the switch assembly 40 moves to the first position, the tray 12 supports the switch assembly 40; when the switch assembly 40 moves to the second position, the switch assembly 40 is partially disengaged from the tray 12.

[0049] In this embodiment of the application, the tray 12 is connected to the container 10 and forms a support structure. When the switch assembly 40 moves, the switch assembly 40 moves closer to or partially away from the tray 12. When the switch assembly 40 moves to the first position, the switch assembly 40 is supported on the support structure.

[0050] For example, the switch assembly 40 includes a chassis 41 and a sealing block 43, the sealing block 43 being disposed on the chassis 41. When the chassis 41 and the sealing block 43 move to a first position, the sealing block 43 seals the discharge port; when the chassis 41 and the sealing block 43 move to a second position, the sealing block 43 opens the discharge port.

[0051] In this embodiment, the sealing block 43 is fixedly mounted on the base plate 41. The shape, size, and volume of the sealing block 43 are consistent with the shape, size, and volume of the discharge port 11 on the container body 10. The sealing block 43 is mounted on the base plate 41 and located between the base plate 41 and the container body 10. The size of the sealing block 43 can be greater than or equal to the diameter of the discharge port 11. When the base plate 41 moves away from the discharge port 11, the sealing block 43 also moves away from the discharge port 11, and the discharge port 11 is exposed. When the base plate 41 moves closer to the discharge port 11, the sealing block 43 also moves closer to the discharge port 11, and the sealing block 43 gradually enters the discharge port 11, completely sealing the discharge port 11 when the base plate 41 moves to the second position.

[0052] In this embodiment, the tray 12 is used to lift and support the chassis 41. The tray 41 can be a fixed L-shape, with the lower end of the L-shape being a flat, fixed shape, or it can be a movable pulley or bearing, the sliding of which can prevent excessive wear. When the chassis 41 moves to the first position, the entire chassis 41 is supported on the tray 12; when the chassis 41 moves to the second position, only a portion of the chassis 41 is supported on the tray 12, meaning that part of the tray 12 and the chassis 41 are no longer in contact.

[0053] For example, the switch assembly 40 further includes a connecting rod 44 and a telescopic actuator 45, wherein the connecting rod 44 is connected to the chassis 41 and the telescopic actuator 45 respectively, the telescopic actuator 45 is connected to the container 10, and the telescopic actuator 45 controls the movement of the chassis 41.

[0054] In this embodiment, the telescopic actuator 45 can be a pneumatic actuator or an electric actuator, and it can extend and retract itself to transmit power to the connecting rod 44 so that it controls the movement of the chassis 41.

[0055] like Figure 8In this embodiment, the switch assembly 40 may include two connecting rods 44 and two telescopic actuators 45. The two connecting rods 44 are distributed on both sides of the chassis 41 and are respectively connected to the two telescopic actuators 45. The telescopic actuators 45 synchronously control the chassis 41 to extend or retract horizontally. When the chassis 41 is extended to the first position by the telescopic actuators 45, the sealing block 43 seals the discharge port 11. When the chassis 41 is retracted to the second position by the telescopic actuators 45, the sealing block 43 partially opens the discharge port 11.

[0056] For example, the switch assembly 40 further includes a rotating shaft 42, which is rotatably connected to the container and the base 41 respectively. When the base 41 rotates around the rotating shaft 42 to a first position, the base 41 is supported on the tray. When the base 41 rotates around the rotating shaft 42 to a second position, the base 41 is partially disengaged from the tray, and the telescopic actuator 45 controls the base 41 to rotate around the rotating shaft 42.

[0057] In this embodiment, the chassis 41 can rotate about the rotation axis 42 and move closer to or further away from the tray 12.

[0058] like Figure 1 In this embodiment, the switch assembly 40 includes a rotating shaft 42, a connecting rod 44, and a telescopic actuator 45. The connecting rod 44 is connected to the chassis 41 and the telescopic actuator 45, respectively. The telescopic actuator 45 is connected to the container 10 or to a fixed position outside the container. The telescopic actuator 45 controls the chassis 41 to rotate around the rotating shaft 42. The rotating shaft 42 is rotatably connected to the container 10 and the chassis 41, respectively. When the chassis 41 rotates around the rotating shaft 42 to a first position, the sealing block 43 seals the discharge port 11. When the chassis 41 rotates around the rotating shaft 42 to a second position, the sealing block 43 opens the discharge port 11.

[0059] For example, the switch assembly 40 further includes a connecting cylinder 46, which is connected to the chassis 41. The shape of the connecting cylinder 46 can be square, round, or the like. The connection between the connecting cylinder 46 and the chassis 41 is tightly fitted together without any gaps. When the chassis 41 and the sealing block 43 move to the second position, the sealing block 43 opens the discharge port, and the upper opening of the connecting cylinder 46 is tightly attached to the discharge port. The sample cup is movably connected to the connecting cylinder 46.

[0060] In this embodiment, the upper edge of the opening of the connecting cylinder 46 is parallel and close to the upper edge of the chassis 41, and a rubber sealing ring is installed in the upper opening of the connecting cylinder 46. When the chassis 41 rotates to the second position, the sealing block 43 also moves out from the discharge port 11, and a portion of the discharge port 11 is exposed to form a discharge port. The connecting cylinder 46 is located directly below the exposed portion of the discharge port 11. The diameter of the connecting cylinder 46 is larger than the discharge opening formed by the discharge port 11 at this time. The grinding material enters the movably connected sample cup 60 through the discharge opening formed by the discharge port 11 and the connecting cylinder 46, completing the discharge operation.

[0061] For example, the grinding assembly 30 includes a grinding ring 31, which is disposed inside the bowl 10.

[0062] In this embodiment, the grinding ring 31 is movably disposed inside the bowl 10. During the grinding process when the bowl 10 is subjected to external force and shakes or rotates, the grinding ring 31 contacts and squeezes the raw material, and grinds the raw material together with the inner wall of the bowl 10.

[0063] For example, the grinding assembly 30 further includes a grinding block 32, which is disposed within the grinding ring 31.

[0064] In this embodiment, the grinding block 32 is movably disposed within the grinding ring 31. During the process of the bowl body 10 being shaken or rotated by external force, the grinding ring 31 and the grinding block 32 come into contact with and squeeze the raw material, and the two grind the raw material together.

[0065] For example, it also includes a cleaning assembly 50, which is detachably and movably connected to the connecting cylinder 46.

[0066] In this embodiment, when grinding is completed and the chassis 41 moves to the second position, the grinding material is discharged from the discharge opening formed by the discharge port 11. The cleaning component 50 is then connected to the connecting cylinder 46. Through the discharge opening formed by the discharge port 11, the cleaning component 50 cleans the inside of the grinding chamber. During the cleaning process, the cleaning component 50 pressurizes the cleaning liquid or gas into the grinding chamber. The grinding device can be in a state of external shaking at this time. Through the combined action of the grinding ring 31, the grinding block 32 and the liquid or gas, the cleaning is completed.

[0067] For example, the cleaning assembly 50 includes: a mounting cylinder 51, a connecting pipe 52, and a cleaning pipe 53, wherein the mounting cylinder 51 and the connecting cylinder 46 are detachably rotatably connected by a thread, the connecting pipe 52 is connected to the mounting cylinder 51, and the cleaning pipe 53 extends into the interior of the mounting cylinder 51 through the side wall therein.

[0068] In this embodiment, the connection between the mounting cylinder 51 and the connecting cylinder 46 is provided with a threaded or snap-fit ​​structure, allowing them to be tightly fitted together. The cleaning pipe 53 is connected to external cleaning liquid or gas. Under pressure, the cleaning liquid or gas is injected into the grinding chamber through the discharge opening formed by the outlet 11. The cleaning liquid or waste liquid or gas passes through the connecting cylinder 46 and the mounting cylinder 51 and then enters the connecting pipe 52 for discharge. The cleaned impurities, waste liquid, or waste gas are discharged from the grinding chamber through the discharge opening formed by the outlet 11, the connecting cylinder 46, the mounting cylinder 51, and the connecting pipe 52 under the action of gravity or pressure, thus completing the cleaning process.
