DETAILED DESCRIPTION
[0022] See also Figure 1-2 The utility model provides a technical solution: an iron ore roughing equipment, including a screening drum 1 and a screen 2. The bottom outer ring of the screening drum 1 is evenly supported with a plurality of legs to achieve stable support for the screening drum 1. A feed hopper 4 is vertically arranged on the right side above the screening drum 1. A discharge pipe 41 connected to the feed hopper 4 is connected below the feed hopper 4. The discharge pipe 41 penetrates into the middle of the screening drum 1. The crushed iron ore raw material is put in through the feed hopper 4, and then falls into the middle of the screening drum 1 through the discharge pipe 41.
[0023] The screen 2 is set to be conical and fixed at the lower position inside the screening drum 1. The iron ore falling into the screening drum 1 will be screened by the conical screen 2, so that small pieces of iron ore will fall below after passing through the screen 2. A first material port 11 is connected to the middle position of the bottom of the screening drum 1. The first material port 11 is connected to the interior of the screening drum 1, and small pieces of iron ore can be discharged to the outside through the first material port 11.
[0024] A horizontal fixed plate 21 is fixed in the middle position of the screen 2, and a rotating rod 3 is vertically and rotatably installed inside the screening drum 1. A stepper motor 35 connected to the rotating rod 3 is installed in the middle position of the surface of the screening drum 1. The stepper motor 35 can drive the rotating rod 3 to rotate when working. The rotating rod 3 vertically penetrates the middle position of the fixed plate 21. The rotating rod 3 is rotatably connected to the fixed plate 21 through a bearing 34 and passes through it. While the rotating rod 3 can rotatably penetrate the fixed plate 21, it can achieve stable support for the fixed plate 21 and the middle position of the screen 2. A baffle 33 is fixed around the outer ring of the rotating rod 3 above the fixed plate 21, and the baffle 33 cover is placed above the bearing 34 to protect the bearing 34 and prevent iron ore from hitting the bearing 34 and damaging it.
[0025] The cam 312 is fixedly mounted on the cam face of the fixing plate 21, and a rotatable roller 311 is installed on the surface of the cam face, and the roller 311 is supported on the bottom surface of the screen 2. When the cam 312 is rotated, the roller 311 can be driven to rotate together, and the roller 311 can be rotated to contact the lower surface of the screen 2, so that the large pieces of iron ore blocked in the screen 2 are pushed upward to avoid being blocked in the mesh. The cam 3 passes through the side of the lower plate 31, and a plurality of triangular plates 314 are evenly welded and fixed between the lower side of the lower plate 31 and the outer surface of the cam 3. A reinforcing rod 312 is transversely welded and fixed between the cam 3 and the lower plate 31. A support rod 313 is connected and fixed between the upper and lower sides of the reinforcing rod 312 and the cam 3. The triangular plate 314, the reinforcing rod 312 and the support rod 313 can all realize the stable connection and fixation of the lower plate 31, ensuring that the roller 311 can always contact and stick to the lower surface of the screen 2.
[0026] The side of the screening drum 1 below the screen 2 is obliquely connected to the second material port 12, and the second material port 12 is connected to the interior of the screening drum 1. A cross bar 32 is laterally fixed to the side of the rotating rod 3 above the fixed plate 21, and an inclined push rod 321 is fixed below the cross bar 32 through a connecting rod 322. The push rod 321 is parallel to the upper surface of the screen 2 and close to the upper surface of the screen 2. Large pieces of iron ore and small pieces of iron ore that have not been screened can be moved, so that all small pieces of iron ore can pass through the screen 2 and be screened to the bottom, and large pieces of iron ore can be moved to the second material port 12, and then discharged from the second material port 12 to the outside.
[0027] When in use, the stepper motor 35 is connected to the control device and powered on. When screening, the stepper motor 35 is started first to drive the rotating rod 3 to rotate, and the cross bar 32 and the supporting rod 321 at the bottom are driven to rotate, and at the same time, the lower plate 31 below and the supporting roller 311 above it are driven to rotate, so that the crushed iron ore to be screened is put into the feed hopper 4, and then falls to the middle position of the screening cylinder 1 through the discharge pipe 41, and then is screened under the action of the screen 2. The small pieces of iron ore fall downward after passing through the screen 2 and pass through the first The large pieces of iron ore blocked in the mesh of the screen 2 are discharged through the material port 11 by the roller 311 which is pressed against the bottom surface of the screen 2 and rolls to the top of the screen 2, and are moved to the top of the screen 2 by the action of the push rod 321 which is driven to rotate above, thereby moving the large pieces of iron ore and the small pieces of iron ore accumulated on the top, ensuring that all the small pieces of iron ore that meet the requirements can pass through the screen 2 and fall downward, and the large pieces of iron ore will eventually be moved to the second material port 12 by the pushing action of the push rod 321 and discharged to the outside of the screening cylinder 1.
