A movable frame 11 is provided at one end of the top of the base 1 away from the bracket 2, and the drum cover 17 is rotatably connected to the movable frame 11.

[0025] As a preferred embodiment, the knocking mechanism includes a top frame 6 arranged on the top of the bracket 2, and one end of the top frame 6 extends to the top of the screen drum 4, and a second fixed plate 20 is provided on the top frame 6, and a telescopic guide rod 24 is provided at the bottom of the second fixed plate 20. The outer side of the telescopic guide rod 24 is provided with a spring 22, and the bottom of the telescopic guide rod 24 is fixedly connected with a knocking block 21 for striking the screen 5. The circumference of the screen drum 4 is evenly provided with protrusions 7 corresponding to the screen 5, and the protrusions 7 correspond to the knocking blocks 21. The cross-sections of the protrusions 7 and the knocking blocks 21 are both quarter-circular, and the protrusions 7 and the arc-shaped surfaces on the knocking blocks 21 slide together.

[0026] In order to adjust the position of the knocking block 21, the second fixed plate 20 is arranged above the top frame 6. The top frame 6 is provided with a through hole 23 corresponding to the telescopic guide rod 24. The lower end of the telescopic guide rod 24 extends to the bottom of the top frame 6 through two or three. A mounting frame 18 is provided on the top of the top frame 6. The mounting frame 18 is provided with a second linear motor 19 for driving the second fixed plate 20 to rise and fall.

[0027] Furthermore, in order to facilitate discharging, a unloading mechanism is also provided, which includes a turntable 8 arranged on one side of the upper end of the bracket 2 and driven to rotate by the reduction motor 3, a connecting seat 9 is provided on the side of the turntable 8 away from the bracket 2, and a connecting rod 10 rotatably connected to the connecting seat 9 is provided on the side of the screen drum 4 close to the bracket 2, and a first fixed plate 12 is provided on the side wall of one end of the screen drum 4 close to the movable frame 11, and a curved groove 14 is provided on the outer side of the first fixed plate 12. The curved groove 14 is arc-shaped, and the circle of the curved groove coincides with the center of the circle of the connection rod 10 rotating around the connecting seat 9, and a driving arm 13 corresponding to the first fixed plate 12 is provided on the side of the drum cover 17, and a guide wheel 16 movably connected to the curved groove 14 is provided on the side wall of one end of the driving arm 13, so that the lateral displacement of the guide wheel 16 can realize the change of the inclination angle of the screen drum 4, and the movable frame 11 is movably connected to the top of the base 1 through a linear guide rail, and a first linear motor 15 for driving the displacement of the movable frame 11 is provided on the end of the top of the base 1 away from the bracket 2.

[0028] Working principle: when in use, the raw material is placed in the screen drum 4, and then the reduction motor 3 is controlled to drive the turntable 8 to rotate. The turntable 8 drives the screen drum 4 to rotate through the connecting seat 9 and the connecting rod 10, and the drum cover 17 rotates accordingly. As the screen drum 4 rotates, the titanium alloy powder is filtered and screened. When the screen 5 needs to be cleaned, the second linear motor 19 is controlled to drive the second fixed plate 20 to move downward until the knocking block 21 corresponds to the protrusion 7. Then, as the screen drum 4 rotates, the protrusion 7 on one side of the screen 5 will touch the knocking block 21, and the arc surface will slide and rub, and then the knocking block 21 will be pressed and gradually move upward, and then the spring 22 will be compressed. When the knocking block 21 separates from the arc surface of the protrusion 7, it will rebound. The spring 22 resets instantly, and then the knocking block 21 falls to knock on the screen 5, which can shake off the particles blocked on the screen 5 and avoid blockage. When cleaning is not needed, the knocking block 21 only needs to be driven upward by the second linear motor 19. After the completion, the first fixed plate 12 is located on the left and right sides of the screen drum 4, and the end of the curved groove 14 close to the movable frame 11 is facing upward, and then the first linear motor 15 is controlled to drive the movable frame 11 to move. The movable frame 11 drives the drum cover 17 to separate from the screen drum 4, and the drum cover 17 drives the guide wheel 16 to move through the driving arm 13, and then under the action of the curved groove 14, the turntable 8 and the connecting seat 9, the screen drum 4 tilts downward away from the end of the bracket 2, and the internal material is discharged.
