Both ends of the grinding chamber are sealed by end covers respectively. A main shaft extends into the grinding chamber through an end cover. A grinding rotor driven to rotate by the main shaft is arranged in the grinding chamber.

[0033] At present, when the grinder is in normal use, after the material is ground by the grinding rotor, it enters the separation chamber through the separator and then flows out from the discharge chamber; however, the separator and the discharge chamber in the general grinder are statically fixed, which may easily cause the material and the grinding medium to block the separator and reduce the grinding efficiency, which is not conducive to the use of the grinder itself; when the grinder of the embodiment of the present invention is in normal use, the grinding material is passed into the interior of the grinding cylinder 2 through the feed pipe, and then the driving motor drives the grinding shaft 3 to rotate, and the grinding shaft 3 drives the grinding rod pin 31 on its surface to rotate. Under the continuous rotation of the grinding rod pin 31, the material inside the grinding cylinder 2 will gradually be ground to the required particle size, and then the material will slowly pass through the discharge chamber. The sieve holes on the surface of the screen 4 enter the lower part of the grinding cylinder 2, and during the rotation of the grinding shaft 3 and the grinding rod pin 31, the bottom end of the grinding rod pin 31 will contact with the top end of the arc frame 5, giving a certain pressure to the arc frame 5, so that the discharge screen 4 moves downward, and the elastic column 41 is compressed and in an extruded state. When the grinding rod pin 31 and the arc frame 5 are separated from each other, the elastic column 41 in the extruded state recovers, thereby driving the discharge screen 4 to vibrate with a certain amplitude, so that the material on the surface of the discharge screen 4 can fall as soon as possible. Setting the discharge screen 4 to be dynamic can prevent the material and the grinding medium from accumulating in blocks on the surface of the discharge screen 4, which is beneficial to the use of the grinder.

[0034] It should be noted that when feeding materials, it is necessary to feed in sections, and the amount of feed and the weight of the discharge screen 4 are less than the elastic force of the elastic column 41, ensuring that the elastic column 41 has sufficient elastic force to shake the discharge screen 4 to facilitate the discharge of materials.

[0040] During operation, when the discharging screen 4 moves, the discharging screen 4 will simultaneously drive the pressure column 12 to move, and the pressure column 12 will move to the side close to the inclined plate 11, and then the pressure column 12 will contact the inclined surface of the inclined plate 11 and squeeze the inclined plate 11. Since the push plate 10 under the inclined plate 11 is slidably connected to the surface of the receiving frame 9, the push plates 10 on both sides will approach each other, pushing the material at the edge of the receiving frame 9 to the middle of the receiving frame 9, which is convenient for the subsequent centralized processing of the material, avoiding the material from being scattered around the receiving frame 9, and reducing the workload of the staff.

[0041] The lower surface of the push plate 10 is rotatably connected to a plurality of rollers 13; the plurality of rollers 13 are equidistantly arranged on the surface of the push plate 10; the lower surface of the rollers 13 is in contact with the material receiving frame 9. The rollers 13 are arranged on the lower surface of the push plate 10, which can reduce the friction between the push plate 10 and the material receiving frame 9, and when the inclined plate 11 is pressed, it will drive the push plate 10 to move a certain distance, thereby facilitating the pushing of materials.

[0042] A telescopic spring 14 is fixedly connected to the surface of the push plate 10; the telescopic spring 14 is connected to the surface of the material receiving frame 9 on one side away from the push plate 10; during operation, when the inclined plate 11 moves, it will simultaneously pull the telescopic spring 14 on the other side, and when the inclined plate 11 and the pressure column 12 move away from each other, the telescopic spring 14 will drive the inclined plate 11 and the push plate 10 to recover, making it convenient for the push plate 10 to push the material again, thereby continuously pushing the materials scattered around, and facilitating the centralized processing of the materials.

[0044] Embodiment 2

[0046] During operation, when the grinder is in normal use, the grinding material is passed into the grinding cylinder 2 through the feeding pipe, and then the driving motor drives the grinding shaft 3 to rotate, and the grinding shaft 3 drives the grinding rod pin 31 on its surface to rotate. Under the continuous rotation of the grinding rod pin 31, the material in the grinding cylinder 2 will be gradually ground to the required particle size, and then the material will slowly pass through the sieve holes on the surface of the discharge screen 4 and enter the bottom of the grinding cylinder 2. During the rotation of the grinding shaft 3 and the grinding rod pin 31, the bottom end of the grinding rod pin 31 will contact the top end of the arc frame 5, giving a certain pressure to the arc frame 5, so that the discharge screen 4 moves downward, and the elastic column 41 is compressed and in an extruded state. When the grinding rod pin 31 and the arc frame 5 are separated from each other, the elastic column 41 in the extruded state recovers, thereby driving the discharge screen 4 to vibrate with a certain amplitude, so that the material on the surface of the discharge screen 4 can fall as soon as possible.

[0047] The arc-shaped grinding rod pin 31 and the arc frame 5 are on the same vertical plane, so that the arc frame 5 can be pressed down more conveniently during the rotation of the grinding rod pin 31, so that the discharge screen 4 and the elastic column 41 are in a pressed state. When the elastic column 41 recovers, the discharge screen 4 is in a shaking state, which is convenient for discharging the ground material and more convenient to use. A compression spring 6 is arranged on the outer surface of the elastic column 41, which can provide a certain supporting force for the discharge screen 4, and when the compression spring 6 recovers from the compressed state, it can drive the discharge screen 4 to vibrate to a large extent, which is convenient for discharging the material.

[0048] When the discharging screen 4 is pressed and moved, the discharging screen 4 will simultaneously move to the side close to the piercing rod 8, and then the piercing rod 8 will pass through the sieve holes on the surface of the discharging screen 4 to dredge the sieve holes on the surface of the discharging screen 4, so as to avoid the problem that too much material on the surface of the discharging screen 4 causes some sieve holes to be blocked, so that the material can completely pass through all the sieve holes and fall; a plurality of piercing rods 8 corresponding to the sieve holes are provided, and the piercing rods 8 at different positions can dredge different sieve holes, and the conical piercing rods 8 can dredge the materials piled together, which is beneficial to the discharging and subsequent processing of the materials; when the discharging screen 4 moves, the discharging screen 4 will simultaneously drive the pressure column 12 to move, and the pressure column 12 will move to the side close to the The push plate 10 below the inclined plate 11 is slidably connected to the surface of the receiving frame 9, so the push plates 10 on both sides will approach each other, and push the materials at the edge of the receiving frame 9, so that the materials are pushed to the middle of the receiving frame 9, which is convenient for the subsequent centralized processing of the materials, and avoids the materials from being scattered around the receiving frame 9, thereby reducing the workload of the staff; a roller 13 is arranged on the lower surface of the push plate 10, which can reduce the friction between the push plate 10 and the receiving frame 9, so that when the inclined plate 11 is pressed, it will drive the push plate 10 to move a certain distance, thereby facilitating the pushing of the materials;

[0049] When the inclined plate 11 moves, it will simultaneously pull the telescopic spring 14 on the other side. When the inclined plate 11 and the pressure column 12 move away from each other, the telescopic spring 14 will drive the inclined plate 11 and the push plate 10 to recover, making it convenient for the push plate 10 to push the material again. Therefore, the materials scattered around can be pushed sustainably, which is convenient for the centralized processing of the materials; an inclined plate 15 is provided, which can facilitate the materials to slide into the concave groove in the middle of the material receiving frame 9 as quickly as possible, and a limiting column 16 is provided, which can limit the position of the push plate 10 to avoid the push plate 10 from being offset during the movement, which is beneficial to the collection of materials; a pulley 17 is provided on the surface of the limiting column 16, which can facilitate the push plate 10 to move on the outer surface of the limiting column 16, avoid the push plate 10 from being stuck, and thus is beneficial to the collection of materials.
