The end is rotatably connected to the inside of the connecting cover 12, the outer surface of the connecting cover 12 is fixedly connected with a fixing rod 19, the outer surface of the fixing rod 19 is symmetrically fixedly connected with a grading screen 20, and the outer surface of the drum 11 is fixedly connected with a plurality of evenly distributed screen plates 13. An iron powder grading and screening device is formed by arranging a mounting base plate 1, a mounting block 2, a first motor 3, a collecting box 5, a trapezoidal block 7, an electric telescopic machine 8, a feeding bin 9, a feeding pipeline 10, a drum 11, a connecting cover 12, a screen plate 13, a collecting channel 14, an arc-shaped collecting plate 15 and a grading screen 20. By arranging a transmission belt 17, a large amount of iron powder inside the drum 11 is moved by the action of the first motor 3 and the transmission belt 17. When multi-stage screening is performed, it can be rotated to speed up the screening speed. There are multiple screen plates 13 and they are evenly distributed in a rectangular array on the outer surface of the drum 11, so that the screening efficiency is improved. The interior of the drum 11 is connected with the interior of the feed bin 9, so that iron powder can enter the drum 11 through the feed bin 9. The interior of the collecting channel 14 is connected with the interior of the collecting box 5, so that the screened iron powder can enter the collecting box 5 through the collecting channel 14. The outer surface of the collecting box 5 is fixedly connected with a handle 6, so that the collecting box 5 can be pulled out from the bottom end of the mounting base plate 1, and the four corners of the bottom end of the mounting base plate 1 are fixedly connected with support rollers 4, so that the device can change its position on the ground.

[0018] The pushing and unblocking component includes an electric telescopic machine 8, the outer surface of the electric telescopic machine 8 is fixedly connected to the outer surface of the feed bin 9, one end of the output shaft of the electric telescopic machine 8 is fixedly connected to a unblocking convex plate 22, and the inside of the feed bin 9 is rotatably connected to a baffle 21. By setting the electric telescopic machine 8, a large amount of iron powder can be put into the device and the feed bin 9 can be unblocked by controlling the movement of the unblocking convex plate 22 by the electric telescopic machine 8 to prevent the feed bin 9 from being blocked. The side of the unblocking convex plate 22 away from the electric telescopic machine 8 corresponds to the internal opening of the feed pipe 10, so that the unblocking convex plate 22 can push the blocked iron powder into the collection channel 14 and into the drum 11.

[0019] Working principle: When a large amount of iron powder enters the drum 11 through the feed pipe 10, the staff can start the first motor 3, and the output shaft of the first motor 3 rotates to drive the first rotating wheel 18 to rotate. The first rotating wheel 18 rotates the second rotating wheel 16 through the transmission belt 17, thereby rotating the rotating rod 23. The rotation of the rotating rod 23 drives the drum 11 to rotate on the connecting cover 12, so that the internal iron powder is graded and screened under the action of the grading screen 20 on the connecting cover 12, and is screened under the action of the screen plate 13 outside the drum 11, thereby accelerating the screening rate. The screened iron powder can enter the arc-shaped collecting plate 15 through the screen plate 13, and then enter the collecting box 5 through the collecting channel 14 for collection;

[0020] When a large amount of iron powder is added at one time and causes the feed bin 9 to be blocked, the staff can start the electric telescopic machine 8. The output shaft of the electric telescopic machine 8 extends to drive the unblocking convex plate 22 to move inside the feed bin 9 toward the opening of the feed pipe 10, and at the same time, the baffle 21 is squeezed upward. The baffle 21 is rotated under the force and pushes a part of the iron powder upward. Under the action of the unblocking convex plate 22, the iron powder at the opening of the feed pipe 10 is squeezed to enter the interior of the feed pipe 10. Then the electric telescopic machine 8 contracts, so that one end of the baffle 21 rotates to contact the bottom of the feed bin 9 to form an inclined surface, so that the iron powder can enter the feed pipe 10 along the inclined surface.

[0021] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
