The outer circumferential side of the mounting frame 18 is fixedly connected to the inner wall of the grinding and screening barrel 1. The mounting frame 18 is provided to more securely fix the grinding shell 4 inside the grinding and screening barrel 1, thereby improving the overall structural stability.

[0041] In a preferred embodiment, a powder outlet hole 8 is provided between the grinding protrusions 6 on the grinding shell 4. The powder outlet hole 8 allows the metal powder generated during the downward movement of metal particles through friction to be discharged through the powder outlet hole 8, thereby improving the powder discharge efficiency.

[0042] The screening mechanism is located inside the grinding screening barrel 1, below the grinding mechanism, and is used to screen the ground metal powder.

[0043] In a preferred embodiment, the screening mechanism includes a linear guide rail 11, a screening assembly, a push-pull assembly, and a pin assembly 16; wherein,

[0044] The linear guide rails 11 are provided in two sets, and the two sets of linear guide rails 11 are symmetrically arranged on two symmetrical wall surfaces inside the grinding and screening barrel 1.

[0045] The screening assembly, located between two sets of linear guide rails 11, includes an annular base plate 12. A U-shaped side plate 13 is fixedly installed on the edge of the top surface of the annular base plate 12. A vertically folding baffle 14 is hinged to the top surface of the annular base plate 12 at the opening of the U-shaped side plate 13, that is, the baffle 14 can be folded vertically, forming a rectangular annular frame together with the U-shaped side plate 13. A screening screen 15 is fixedly installed on the inner side of the annular base plate 12.

[0046] The latch assembly 16, also known as the latch, is an anti-theft component that prevents doors and windows from being opened from the outside. Modern door and window latches are generally made of metal, while ancient door and window latches were made of wood. The latch is generally divided into two parts: one part has a movable rod, and the other part is a latch hole, also called the latch "nose". There are two sets of latch assemblies 16, which are symmetrically arranged between the top ends of the baffle 14 and the top surface of the U-shaped side plate 13 to limit the position of the baffle 14.

[0047] The push-pull assembly includes an electric push rod 17, which is arranged parallel to the length direction of the linear guide rail 11. One end of the electric push rod 17 is fixedly disposed on the inner wall of the grinding and screening barrel 1, and the other end is fixedly connected to the side of the U-shaped side plate 13 away from the baffle 14. It is used to drive the screening assembly to perform a small range of reciprocating motion along the direction of the linear guide rail 11, so as to reduce the probability of clogging of the screening screen 15.

[0049] The feeding mechanism, located at the top of the grinding and screening barrel 1, is used to transport metal particles into the interior of the grinding mechanism.

[0050] In a preferred embodiment, an annular guide cylinder 19 is provided inside the grinding and screening barrel 1 between the screening mechanism and the grinding mechanism. The inner wall of the annular guide cylinder 19 is set in a conical shape. The bottom outlet of the annular guide cylinder 19 is located inside the U-shaped side plate 13.

[0051] Driven by the electric push rod 17, the screening assembly reciprocates within a small range along the direction of the linear guide rail 11. The bottom end of the annular guide tube 19 is always located inside the U-shaped side plate 13 to prevent metal powder from leaking to the outside of the screening assembly.

[0052] In a preferred embodiment, the feeding mechanism includes a feeding pipe 20, which is fixedly disposed through the top of the grinding and screening barrel 1 and extends into the interior of the grinding shell 4; a flared feeding pool 21 is fixedly disposed at the top end of the feeding pipe 20.

[0053] The working principle of this novel invention is as follows:

[0054] During operation, metal particles are fed into the grinding shell 4 through the feed tank 21 and feed pipe 20. The drive motor 10 drives the transmission shaft 9 to rotate, which in turn drives the grinding block 5 to rotate. The grinding protrusions 6 between the grinding block 5 and the grinding shell 4 grind the metal particles. The ground metal powder enters the screening mechanism through the powder outlet 7 for screening. At the same time, when the metal particles that are relatively high between the grinding block 5 and the grinding shell 4 move downward, some metal powder will be generated due to the friction between the metal particles and the action of the grinding block 5. This metal powder can be discharged through the powder outlet hole 8 set on the wall of the grinding shell 4, further improving the powder discharge efficiency.

[0055] After grinding, the metal powder is guided by the annular guide tube 19 and enters the inner side of the U-shaped side plate 13. It is then screened by the screening screen 15. During the screening process, the screening assembly is driven by the electric push rod 17 to move back and forth along the square of the linear guide rail 11, which reduces the probability of the screening screen 15 clogging during the screening process. The screened metal powder is discharged through the bucket-shaped discharge port 3.
