[0031] In actual application of this embodiment, when the automatic discharging crusher is used to crush coal, the first shaft roller 201 and the second shaft roller 202 are rotatably assembled on the first frame 101 and the third frame 103 respectively, and the first shaft roller 201 and the second shaft roller 202 are respectively stacked with the first shaft disc 203 and the second shaft disc 204, the first shaft disc 203 is gap-set in the spacing groove of the second shaft disc 204, the second shaft disc 204 is set in the spacing groove of the first shaft disc 203, and the forward milling teeth 205 and the reverse milling teeth 206 do not mechanically interfere with the second shaft disc 204 and the first shaft disc 203. When the coal blocks to be processed are transported between the primary screening cylinder 301 and the shaft ring 401, the coal blocks pass through the shaft ring 401 and collide with the primary screening cylinder 301 under the action of gravity. The top of the screen drum 301, and then the coal blocks fall onto the material guide component 5 during the process of rolling along the outer wall of the primary screen drum 301. The material guide component 5 guides the rolling coal blocks from the side of the discharge port 303 to the inside of the primary screen drum 301, so that the coal blocks fall between the first shaft roller 201 and the second shaft roller 202. The first shaft roller 201 and the second shaft roller 202 rotate in opposite directions by default in the working state, and the rotation direction is limited to one side of the coal blocks, so that the coal is continuously squeezed and crushed between the forward milling teeth 205 and the reverse milling teeth 206. The crushed coal powder particles pass through the gap between the first shaft disc 203 and the second shaft disc 204 and fall to the bottom side of the primary screen drum 301 along the second direction y, and are continuously accumulated on the inner wall of the primary screen drum 301. The primary screen drum 301 is in the driving state. The primary screening drum 301 rotates in conjunction with the first shaft roller 201 and the second shaft roller 202, so that during the rotation of the primary screening drum 301, the coal powder accumulated on the bottom side thereof is constantly turned over, and is constantly screened out through the primary screening holes 302 during the turning process, and the screened out large-size coal continuously moves toward the side of the discharge port 303 while following the rolling of the primary screening drum 301. When the large-size coal moves to the edge of the discharge port 303, it immediately falls onto the secondary screening drum 402 at the outer diameter end of the primary screening drum 301. The two groups of secondary screening drums 402 rotate in conjunction with the primary screening drum 301, and during the rotation of the secondary screening drum 402, the secondary screening holes 403 thereon can roll and screen out the small-size coal, while the large-size coal that slides out through one side of the discharge port 303 falls between the clamping plates 404. The re-screening drum 402 rotates circumferentially, and the clamping plate 404 can continuously lift the large-size coal in the second direction y until the large-size coal falls onto the material guide assembly 5, and then rolls to the top of the first shaft roller 201 and the second shaft roller 202 again, so that the large-size coal and the coal blocks roll down to between the first shaft disc 203 and the second shaft disc 204. Under the mutual extrusion of the first shaft disc 203 and the second shaft disc 204 and the coal and the coal blocks, the large-size coal can be squeezed and crushed for the second time, so as to achieve the purpose of refining the coal. When the primary screening drum 301 rotates circumferentially, when the crushed coal falls to one side of the bottom position of the primary screening drum 301, some wet coal particles will be blocked in the primary screening hole 302, causing the screening efficiency of the primary screening drum 301 to continuously decrease.When the blocked coal particles follow the primary screening cylinder 301 to rotate to the top position of the primary screening cylinder 301, the coal blocks directly hit the outer diameter end of the primary screening cylinder 301 under the action of gravity, so that the primary screening cylinder 301 generates continuous vibration in the second direction y. On the one hand, the vibration effect causes the wet coal particles blocked in the primary screening hole 302 to fall off, and on the other hand, the primary screening cylinder 301 is in a vibrating state as a whole, which can accelerate the screening of coal particles at the bottom position of the primary screening cylinder 301, effectively utilize the gravitational potential energy of the coal blocks falling on the conveyor belt, achieve the purpose of energy saving and environmental protection, and at the same time improve the screening efficiency of coal after crushing, and reduce the blocking of the filter structure by wet coal particles.

[0032] See also Fig. 9 In a preferred embodiment of the present invention, the frame assembly 1 also includes a driver 104, a driving shaft 105, a rolling wheel 106 and a driving gear 107.

The two groups of rolling wheels 106 are respectively connected to the outer walls of the two groups of complex screen drums 402 in rolling connection. The end of the driving shaft 105 is also fixedly connected to a driving gear 107.

[0033] In actual application of this embodiment, the two groups of drivers 104 respectively control the first shaft roller 201 and the second shaft roller 202 to rotate in opposite directions, and the driving shaft 105 is connected to any group of drivers 104 in transmission, so that during the rotation of the driving shaft 105, the two groups of rolling wheels 106 coaxially arranged thereon can rotate synchronously, and use friction to drive the secondary screen drum 402 to roll, so that the two groups of secondary screen drums 402 rotate simultaneously relative to the shaft ring 401, and the sieve hole of the secondary screen hole 403 is smaller than the sieve hole diameter of the primary screen hole 302, so that the coal particle size obtained after multiple crushing meets the required particle size.

[0034] In one case of the present embodiment, the clamping plate 404 is tiltedly arranged in the inner wall of the re-screening cylinder 402, so that the large-particle coal that falls into the re-screening cylinder 402 can be stuck in the angle between the clamping plate 404 and the re-screening cylinder 402 when it rotates with the re-screening cylinder 402, until the clamping plate 404 moves close to the top side of the primary screening cylinder 301, and the clamping plate 404 tends to be parallel to the horizontal plane. At this time, the large-particle coal on the clamping plate 404 slides onto the material guide assembly 5 under the action of gravity.

[0036] In actual application of this embodiment, two groups of blocking plates 207 are respectively arranged at the two ends of the first shaft roller 201 and the second shaft roller 202, and the outer diameter of each group of blocking plates 207 is set to have a gap with the inner wall of the primary screening cylinder 301. Under the condition of not interfering with the rotation of the primary screening cylinder 301, it can prevent coal blocks from sliding through the gap between the primary screening cylinder 301 and the first shaft disk 203 and the second shaft disk 204, and a plurality of spaced blocking plates 207 are respectively arranged between the spacing grooves of the first shaft disk 203 and the second shaft disk 204.

[0037] See also Figure 7 In a preferred embodiment of the present embodiment, the primary screening assembly 3 also includes an outer gear ring 305 and a transmission gear 306, the outer gear ring 305 is fixedly arranged at the outer diameter end of the material blocking port 304, one end of the transmission gear 306 is meshed and connected with the driving gear 107, and the other end of the transmission gear 306 is meshed and connected with the outer gear ring 305.

[0038] In actual application of this embodiment, the material blocking port 304 is arranged at the other end of the primary screening cylinder 301, and the diameter of the material blocking port 304 is smaller than the diameters of the primary screening cylinder 301 and the discharge port 303, so that the coal on the inner wall side of the primary screening cylinder 301 can be blocked at one end of the material blocking port 304, and the outer tooth ring 305 arranged on the outer wall side of the material blocking port 304 is meshed with the transmission gear 306, and the other end of the transmission gear 306 is meshed with the driving gear 107, so that the driving shaft 105 can synchronously drive the primary screening cylinder 301 to rotate during the rotation process, so that the first shaft roller 201, the second shaft roller 202, the primary screening cylinder 301 and the secondary screening cylinder 402 of the crusher can move synchronously.

[0039] In one case of the present embodiment, a receiving ring 405 is also installed on the secondary screen cylinder 402 near the discharge port 303, and the distance of the receiving ring 405 in the first direction x exceeds that of the primary screen cylinder 301, so that the coal dropped from the discharge port 303 can fall back into the secondary screen cylinder 402 along the receiving ring 405, and prevent the coal in the secondary screen cylinder 402 from sliding out along the first direction x.

[0040] See also Figure 3In a preferred embodiment of the present invention, the automatic discharging crusher based on coal equipment processing also includes a material guide component 5, the material guide component 5 includes a material guide plate 501, an inclined guide groove 502, a discharge plate 503 and a discharge groove 504, two groups of the material guide plates 501 are fixedly arranged at one end of the first frame 101, and a gap is set between the inner wall of the material guide plate 501 and the outer wall of the primary screening cylinder 301, an inclined guide groove 502 inclined along the second direction y is arranged inside the material guide plate 501, the discharge plate 503 is fixedly arranged at one end of the first frame 101 and arranged inside the primary screening cylinder 301, one end of the discharge plate 503 is connected with the two groups of inclined guide grooves 502, and a discharge groove 504 is also arranged in the middle of the discharge plate 503.

[0041] In actual application of this embodiment, the two groups of guide plates 501 are respectively arranged on both sides of the outer wall of the primary screening cylinder 301, and are arranged between the cavities of the primary screening cylinder 301 and the secondary screening cylinder 402, so that the coal blocks passing through the shaft ring 401 and falling to the top side of the primary screening cylinder 301 fall onto the inclined guide groove 502 during the rolling process, and the inclined guide groove 502 is inclined in the second direction y, so that the coal blocks slide along the inclined guide groove 502 to the discharge plate 503, and the discharge plate 503 is arranged in the inner cavity of the primary screening cylinder 301, and the discharge trough 504 is arranged between the first shaft roller 201 and the second shaft roller 202, so that the coal blocks pass through the discharge trough 504 and directly fall on the first shaft plate 203 and the second shaft plate 204. The coal blocks are crushed between the primary screening cylinder 301 and the secondary screening cylinder 402 on the side of the material blocking port 304, thereby crushing the coal blocks. When the crushed coal blocks fall on the bottom side of the primary screening cylinder 301, the small-size coal will be distributed on the bottom side of the primary screening cylinder 301 during the rolling process, and will fall onto the secondary screening cylinder 402 on the side of the discharge port 303 and the secondary screening cylinder 402 on the side of the material blocking port 304 during the screening process. Since the large-size coal is discharged along the discharge port 303, the secondary screening cylinder 402 at one end of the material blocking port 304 can quickly screen and discharge the small-size coal, while the retained large-size coal follows the clamping plate 404 on the inner wall side of the secondary screening cylinder 402 to rotate to one end of the material guide plate 501, so that the large-size coal slides into the material guide plate 501, thereby realizing multiple crushing of the large-size coal.

[0043] In actual application of this embodiment, the feed pipe 601 is fixedly arranged at the bottom of the shaft ring 401, and the rotary disk 603 is rotatably assembled on the feed pipe 601. When the rotary disk 603 reciprocates on one side of the feed pipe 601, the coal blocks transported into the feed pipe 601 at one end can pass through the semi-cylinder groove 602 and fall onto the semi-cylinder sleeve 604, and slide along the guide port 605 at the bottom of the semi-cylinder sleeve 604 to the primary screening cylinder 301, so that the gravitational potential energy of the coal blocks is converted into kinetic energy, and the kinetic energy of the coal blocks in the collision process is partially transmitted to the feed pipe 601, so that the feed pipe 601 vibrates continuously, thereby driving the shaft ring 401 to vibrate synchronously.
