The side plate is hollow, and the multiple turntables are all arranged inside the side plate. The multiple striking heads are all in contact with the side wall of the grinding mill discharge hopper. The striking heads are pushed outward by the connecting springs and are brought into contact with the side wall of the grinding mill discharge hopper, so that the striking heads strike the side wall of the grinding mill discharge hopper when rotating.
[0010] Preferably, a threaded plate is fixedly connected to the bottom of the fixed sleeve, the threaded rod passes through the threaded plate and is threadedly connected to the threaded plate, a rotating ring is rotatably connected inside the horizontal plate, limit blocks are fixedly connected to both sides inside the rotating ring, limit grooves are opened on both sides of the threaded rod, and the two limit blocks are slidably connected to the two limit grooves and adapted to the two limit grooves respectively.

Horizontal grooves are opened on both sides of the sliding rod. The two limiting plates are slidably connected to the two horizontal grooves and are adapted to the two horizontal grooves. The limiting plates limit the horizontal grooves, thereby driving the sliding rod to rotate synchronously.
[0012] Preferably, a fixed spring is provided inside the rotating sleeve, and the two ends of the fixed spring are fixedly connected to the rotating sleeve and the slide rod respectively. The slide rod passes through the front guide plate and is rotatably connected to the front guide plate.

[0017] 1. This ultrafine grinding mill, which facilitates material discharge, uses connecting springs to limit the striking heads. Multiple striking heads strike the side wall of the mill's discharge hopper, thereby knocking down the dust from the inner wall of the discharge hopper and preventing blockage at the discharge port. By setting up a turntable and striking head structure, driven by the rotating shaft, multiple striking heads continuously strike the side wall of the mill's discharge hopper under the action of connecting springs, effectively shaking off the dust adhering to the hopper wall, avoiding blockage, and ensuring smooth material discharge.
[0018] 2. This ultrafine grinding mill, which facilitates material discharge, uses a threaded rod to drive a threaded plate and a fixed sleeve to move up and down reciprocally. This, in turn, moves a horizontal plate and a rotating sleeve, which in turn moves a front guide plate and a side plate. The side plate then moves a rotating shaft, which in turn moves multiple turntables and striking heads. This causes the striking heads to move along the side walls of the mill's discharge hopper. Simultaneously, a diagonal rod limits and guides the front and rear guide plates, ensuring that the side plates remain in contact with the sides of the mill's discharge hopper and that the multiple striking heads are in contact with the side walls of the mill's discharge hopper. The guide rail also guides the limiting sleeve, thereby improving the stability of the striking heads. Attached Figure Description

[0028] like Figures 1-7 As shown, this utility model embodiment provides an ultrafine grinding mill for easy material discharge, including a grinding mill discharge hopper 1. A threaded rod 2 is rotatably mounted on the front side of the grinding mill discharge hopper 1. A horizontal plate 3 is provided on the outer side of the threaded rod 2. A fixing sleeve 4 is fixedly connected to the bottom of the horizontal plate 3. Rotating sleeves 5 are rotatably connected to both sides of the fixing sleeve 4. Side plates 6 are provided on both sides of the grinding mill discharge hopper 1. A front guide plate 7 and a rear guide plate 27 are fixedly connected to the two ends of the side plates 6, respectively. A rotating shaft 8 is rotatably connected inside the side plates 6. Multiple turntables 9 are fixedly connected to the outer side of the rotating shaft 8. Multiple striking heads 10 are slidably connected in a circular array inside the multiple turntables 9. Multiple connecting springs 11 are provided inside the turntables 9. The two ends of the connecting springs 11 are fixedly connected to the striking heads 10 and the turntables 9, respectively. The side plates 6 are hollow, and the multiple turntables 9 are all located on the side plates. Inside the 6, multiple striking heads 10 are attached to the side wall of the discharge hopper 1 of the grinding mill. The striking heads 10 are pushed to move outward by the connecting spring 11, and the striking heads 10 are attached to the side wall of the discharge hopper 1 of the grinding mill, so that the striking heads 10 strike the side wall of the discharge hopper 1 of the grinding mill when rotating. The bottom of the fixed sleeve 4 is fixedly connected to a threaded plate 15. The threaded rod 2 passes through the threaded plate 15 and is threadedly connected to the threaded plate 15. The inside of the horizontal plate 3 is rotatably connected to a rotating ring 12. Limiting blocks 13 are fixedly connected to both sides of the rotating ring 12. Limiting grooves 14 are opened on both sides of the threaded rod 2. The two limiting blocks 13 are slidably connected to the two limiting grooves 14 and are adapted to the two limiting grooves 14. The limiting grooves 14 limit the limiting blocks 13, thereby driving the limiting blocks 13 and the rotating ring 12 to rotate.
[0029] A first bevel gear 16 is fixedly connected to the bottom of the rotating ring 12. A second bevel gear 17 is fixedly connected to one end of the rotating sleeve 5 inside the fixed sleeve 4. The first bevel gear 16 and the second bevel gear 17 are meshed together. Limiting plates 18 are formed on both sides inside the rotating sleeve 5. A sliding rod 20 is slidably connected inside the rotating sleeve 5. A transverse groove 21 is opened on both sides of the sliding rod 20. The two limiting plates 18 are slidably connected to the two transverse grooves 21 and are adapted to the two transverse grooves 21. The limiting plates 18 limit the transverse grooves 21, thereby driving the sliding rod 20 to rotate synchronously. A fixing spring 19 is set inside the rotating sleeve 5. The two ends of the fixing spring 19 are fixedly connected to the rotating sleeve 5 and the sliding rod 20 respectively. The sliding rod 20 passes through the front guide plate 7 and is rotatably connected to the front guide plate 7. A third bevel gear 22 is fixedly connected to one end of the rotating shaft 8 and the sliding rod 20 close to each other. The third bevel gears 22 mesh with each other, causing the slide bar 20 to rotate and drive the rotating shaft 8 to rotate. The front and rear ends of the mill discharge hopper 1 are fixedly connected with inclined rods 23. The front guide plate 7 and the rear guide plate 27 are slidably connected to the outside of the four inclined rods 23 respectively. The inclined rods 23 limit and guide the front guide plate 7 and the rear guide plate 27, thereby supporting the rotating shaft 8 and improving the stability of the rotating shaft 8 when moving. The rear ends of the horizontal plate 3 are fixedly connected with limit sleeves 25. The front ends of the mill discharge hopper 1 are fixedly connected with guide rails 24. The two limit sleeves 25 are slidably connected to the outside of the two guide rails 24 respectively. The guide rails 24 limit the limit sleeves 25, thereby guiding the horizontal plate 3. The front end of the mill discharge hopper 1 is equipped with a motor 26, and the output end of the motor 26 is fixedly connected to the threaded rod 2.
[0030] In use, when the hopper 1 of the grinding mill is discharging material, the motor 26 is started, which drives the threaded rod 2 to rotate. When the threaded rod 2 rotates, it drives the threaded plate 15 and the fixed sleeve 4 to move up and down, thereby driving the horizontal plate 3 and the rotating sleeve 5 to move. The rotating sleeve 5 drives the front guide plate 7 and the side plate 6 to move, which in turn drives the rotating shaft 8 to move. The rotating shaft 8 then drives multiple turntables 9 and striking heads 10 to move, causing the striking heads 10 to move on both sides of the hopper 1 of the grinding mill. At the same time, the inclined rod 23 limits and guides the front guide plate 7 and the rear guide plate 27, so that the side plate 6 is kept in contact with the side edge of the hopper 1 of the grinding mill, and the multiple striking heads 10 are in contact with the side wall of the hopper 1 of the grinding mill. Meanwhile, the guide rail 24 guides the limiting sleeve 25, thereby improving the stability of the striking heads 10.
[0031] When the rotating sleeve 5 drives the sliding rod 20 to move, it in turn moves the rear guide plate 27 and the side plate 6. The sliding rod 20 extends and retracts inside the rotating sleeve 5, limiting the side plate 6. Simultaneously, the threaded rod 2 rotates, causing the limiting groove 14 to limit the limiting block 13, thereby driving the rotating ring 12 to rotate. This rotating ring 12 then drives the first bevel gear 16 to rotate, which in turn drives the second bevel gear 17 to rotate. The second bevel gear 17 then drives the rotating sleeve 5 to rotate, causing the rotating sleeve 5 to rotate during its reciprocating movement. This causes the limiting plates 18 on both sides of the rotating sleeve 5 to limit the transverse groove 21, thus causing the rotating sleeve 5 to drive the sliding rod 20 to rotate, which in turn drives the transverse groove 21 to rotate. During the rotation of the slide bar 20, the slide bar 20 is driven by the third bevel gear 22, which drives the rotating shaft 8 to rotate. This causes the rotating shaft 8 to drive multiple turntables 9 to rotate. When the multiple turntables 9 rotate, they drive multiple striking heads 10 to rotate, causing the multiple striking heads 10 to extend outwards during the swinging motion. The striking heads 10 are limited by the connecting spring 11. The multiple striking heads 10 strike the side wall of the mill discharge hopper 1, thereby knocking down the dust on the inner wall of the mill discharge hopper 1 and preventing the discharge port from being blocked. By setting up the structure of turntables 9 and striking heads 10, under the drive of the rotating shaft 8, the multiple striking heads 10 continuously strike the side wall of the mill discharge hopper 1 under the action of the connecting spring 11, effectively shaking off the dust attached to the hopper wall, avoiding blockage, and ensuring smooth discharge.
