Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and more specifically, to an automatic sample-dispensing grinding equipment. Background Technology

[0002] A grinder is a laboratory or industrial device used to grind solid materials into finer particles or powders. This equipment is widely used in fields such as chemistry, pharmaceuticals, food, geology, materials science, and environmental science. The primary purpose of a grinder is to reduce the particle size of materials through physical action to facilitate further analysis, processing, or use.

[0003] A search revealed an existing patent (publication number: CN208302993U) disclosing a grinding device with automatic feeding function, including a frame, a storage hopper, a grinding box, and a feeding mechanism. The storage hopper is equipped with a baffle plate, a scraper plate, a filter screen, and a drive cylinder. The feeding mechanism includes a lifting frame, a vertical motor, a vertical lead screw, a vertical guide rod, a horizontal motor, a horizontal lead screw, a sliding plate, and a feeding belt. The vertical motor, vertical lead screw, and vertical guide rod cause the lifting frame to perform vertical reciprocating motion, and the horizontal motor, horizontal lead screw, and sliding plate cause the feeding belt to perform horizontal reciprocating motion. The grinding box is mounted on the frame, the storage hopper is located on top of the grinding box, and the feeding mechanism is located on the left side of the storage hopper, allowing the output end of the feeding belt on the feeding mechanism to enter directly above the storage hopper under the push of the horizontal motor.

[0026] In this embodiment, the feeding lifting device 2 includes: a limiting rod 201 fixedly installed on the top of the support plate 1, a top plate 202 fixedly installed on the top of the limiting rod 201, a threaded rod 203 movably installed between the limiting rod 201 and the top plate 202, a motor 204 fixedly installed on the top of the top plate 202, the drive end of the motor 204 being fixedly connected to the top of the threaded rod 203, and a moving block 205 movably installed on the outer surfaces of the limiting rod 201 and the threaded rod 203.

[0027] In the working principle of the feeding lifting device 2, the motor 204 is fixedly connected to the top of the threaded rod 203 through its drive end, thereby driving the rotation of the threaded rod and causing the moving block 205 to move up and down along the threaded rod to achieve the lifting function. In this way, the height of the moving block 205 can be precisely controlled to adapt to different feeding needs.

[0028] In this embodiment, the uniform feeding device 3 includes: a fixing plate 301 fixedly installed at the bottom of the top plate 202, a motor 302 fixedly installed on one side of the fixing plate 301, a threaded rod 303 movably installed on the inner side of the fixing plate 301, and one end of the threaded rod 303 fixedly connected to the drive end of the motor 302.

[0029] In this embodiment, the uniform feeding device 3 further includes: a fixing plate 304 fixedly installed at the bottom of the top plate 202, a limiting rod 305 fixedly installed on the inner side of the fixing plate 304, a movable block 306 movably sleeved on the threaded rod 303 and the limiting rod 305, and a uniform feeding component 307 assembled at the bottom of the movable block 306.

[0030] In this embodiment, the uniform material spreading component 307 includes: a storage box 308 fixedly installed at the bottom of the movable block 306; an extension plate 309 fixedly installed on one side of the storage box 308; an electric lifting rod 310 fixedly installed on the top of the extension plate 309; a lifting frame 311 fixedly installed on the top of the electric lifting rod 310; an electric roller 312 movably installed inside the storage box 308; one end of the electric roller 312 fixedly connected to the inner side of the lifting frame 311; and a material conveying pipe 313 fixedly installed on one side of the storage box 308.

[0031] The working principle of the uniform feeding device 3 involves the connection between motor 302 and threaded rod 303. The motor drives the threaded rod to rotate, causing the moving block 306 to move along the threaded rod 303. The moving block 306 is equipped with a uniform feeding component 307, and its bottom storage box 308 is connected to the lifting frame 311 via an electric roller 312. By controlling the distance between the electric roller 312 and the bottom gap of the storage box 308, uniform and equal output of material in the storage box 308 is achieved. The electric lifting rod 310 on the extension plate 309 controls the height of the lifting frame 311 to adjust the position of material output. The conveying pipe 313 transports the material in the storage box 308 to the required location, achieving uniform feeding. Example

[0033] In the automatic sample feeding grinder, the sample conveying device 4 works by having a motor 3 403 drive a threaded rod 3 402 to rotate, causing a movable block 404 to move along the threaded rod, which in turn drives the conveyor belt 405 to transport the sample. This design allows for precise control of the sample delivery volume and speed, ensuring the continuity and uniformity of the grinding process.

[0036] The working principle of the sample grinding device 5 involves a motor 504 driving a rotating shaft 505 to rotate, causing the grinding rod 506 at the bottom of the shaft 505 to rotate accordingly, grinding the sample. A cleaning rod 507 rotates on the outer surface of the shaft 505 to remove residues from the grinding tank 508, maintaining a clean grinding environment.
