[0051] Example 2

[0052] Reference Figure 2 This embodiment differs from the first embodiment in that: a coal crushing device includes the crushing device S as described above, including a crushing component 100, including a material passing component 101, and a crushing component 102 provided in the material passing component 101;

[0053] The material shaking component 200 includes a rotating plate 201 arranged in the material passing component 101, a synchronous component 202 connected to the end of the rotating plate 201, and a driving component 203 arranged between the crushing component 102 and the synchronous component 202; wherein, the driving component 203 can drive the rotating plate 201 to rotate; there are two groups of rotating plates 201, and the two groups of rotating plates 201 are arranged above the crushing component. After the coal blocks enter the material passing component 101, the crushing component 102 drives the synchronous component 202 through the driving component 203, so that the two groups of rotating plates 201 rotate in opposite directions to squeeze the coal blocks and perform preliminary crushing on them. After the preliminary crushing, the coal blocks enter the crushing component 102 to be crushed.

[0054] Specifically, the material passing component 101 includes a square frame 101a and a material guide hopper 101b arranged at the bottom of the square frame 101a; wherein, the rotating plate 201 is arranged in the square frame 101a, and the material guide hopper 101b is fixedly connected to the bottom of the square frame 101a, and the crushing component 102 and the material shaking component 200 are both arranged in the square frame 101a, and the material shaking component 200 is arranged above the crushing component 102.

[0055] Furthermore, the crushing assembly 102 includes a drive motor 102a provided on one side of the square frame 101a and a crushing roller 102b provided in the square frame 101a; wherein, the drive motor 102a is connected to the crushing roller 102b, and the drive motor 102a is installed on one side of the square frame 101a. Two groups of crushing rollers 102b are rotatably connected in the square frame 101a. The output end of the drive motor 102a is connected to one group of crushing rollers 102b, and one end of the two groups of crushing rollers 102b is connected to a gear set. The drive motor 102a drives the crushing rollers 102b to rotate, and the gear set causes the two groups of crushing rollers 102b to rotate in relative directions. The two groups of crushing rollers 102b rotate to squeeze and crush the coal blocks.

[0056] Furthermore, the synchronization component 202 includes a sector tooth plate 202a provided at the end of the rotating plate 201, a rack 202b engaged with one side of the sector tooth plate 202a, and a horizontal plate 202c provided on the rack 202b. A square frame 101a is extended from one end of each of the two sets of rotating plates 201 and connected to the sector tooth plate 202a. A rack 202b is slidably connected to one side of the square frame 101a, and the two sets of sector tooth plates 202a are respectively engaged with both sides of the rack 202b. Two sets of horizontal plates 202c are fixedly connected to the rack 202b. The driving motor 102 When a drives the crushing roller 102b to rotate, the driving component 203 synchronously drives the rack 202b to slide back and forth. The reciprocating sliding of the rack 202b pushes the sector tooth plate 202a to rotate back and forth. The sector tooth plate 202a drives the rotating plate 201 to rotate. When the coal block enters the square frame 101a, it first falls between the two groups of rotating plates 201. The reciprocating rotation of the two groups of rotating plates 201 intermittently squeezes the coal block and performs preliminary crushing. The coal block then falls into the crushing roller 102b for further crushing. By crushing the coal block multiple times, the coal block crushing efficiency is improved.

[0057] Furthermore, the driving assembly 203 includes a rotating shaft 203a provided on one side of the square frame 101a, a cam 203b provided on the outside of the rotating shaft 203a, and a synchronous gear set 203c provided between the driving motor and the rotating shaft 203a; wherein the horizontal plate 202c cooperates with the cam 203b, the rack 202b has a through slot 202d corresponding to the rotating shaft 203a, and the rotating shaft 203a is rotatably connected to one side of the square frame 101a. A cam 203b is fixedly connected and arranged between the two sets of horizontal plates 202c. A synchronous wheel set 203c is provided on the output end of the driving motor 102a at the rotating shaft 203a. The driving motor 102a drives the cam 203b to rotate through the synchronous wheel set 203c. The cam 203b rotates in a first direction to conflict with the upper horizontal plate 202c, causing the rack 202b to slide upward. The cam 203b rotates in a second direction to conflict with the lower horizontal plate 202c, causing the rack 202b to slide downward.

[0058] The rest of the structure is the same as that of Example 1.

[0059] Operation process: The coal blocks fall between the two sets of rotating plates 201, and the driving motor 102a drives the two sets of crushing rollers 102b to rotate in opposite directions. At the same time, the driving motor 102a drives the rotating shaft 203a to rotate through the synchronous wheel set 203c, and the rotating shaft 203a drives the cam 203b to rotate. During the rotation process, the cam 203b alternately conflicts with the upper and lower cross plates 202c, and then drives the rack 202b to slide back and forth. The rack 202b reciprocates and drives the fan-shaped toothed plate 202a to rotate back and forth, so that the two sets of rotating plates 201 intermittently squeeze the coal blocks, and the coal blocks are initially crushed. The coal blocks that reach a certain particle size fall between the two sets of crushing rollers 102b, and the two sets of crushing rollers 102b further crush them. The crushing efficiency is improved through multiple crushing of the coal blocks.

The sieve bucket assembly 302 is movably provided in the tank body 301 through the limiting component 403. The driving portion 401 can push the sieve bucket assembly 302 to rise. When the sieve bucket assembly 302 rises, it is guided by the limiting component 403. During the rising process of the sieve bucket assembly 302, the pushing component 402 pushes it to rotate. A feed port is provided at the top of the tank body 301, and a discharge port is provided at the bottom.

[0064] The driving assembly 402 includes a fixing member 402a provided on the inner wall of the tank body 301, a reciprocating spring 402b provided on the fixing member 402a, and a retaining member 402c provided between the fixing member 402a and the sieve bucket assembly 302. The fixing member 402a and the retaining member 402c are each provided in two sets. When the driving unit 401 pushes the movable cylinder 302a upward, the reciprocating spring 402b provided via the fixing member 402a pushes the movable cylinder 302a to rotate via the retaining member 402c.

[0065] The fixing member 402a includes two sets of fixing blocks 402a-1 fixed on the inner wall of the tank 301, and an arc-shaped rod 402a-2 disposed between the two sets of fixing blocks 402a-1; wherein the reciprocating spring 402b is sleeved on the outer side of the arc-shaped rod 402a-2;

[0066] The blocking member 402c includes a cross bar 402c-1 sleeved on the outside of the arc rod 402a-2, and a round rod 402c-2 fixed to the bottom of the guide plate 302c; wherein, the reciprocating spring 402b pushes the cross bar 402c-1 to always resist the round rod 402c-2, and the two ends of the reciprocating spring 402b respectively resist the cross bar 402c-1 and the fixed block 402a-1, and the cross bar 402c-1 has an arc groove P that matches the round rod 402c-2. The reciprocating spring 402b pushes the arc groove P of the cross bar 402c-1 to correspond to the side of the round rod 402c-2, and then the round rod 402c-2 limits the cross bar 402c-1 to prevent it from rotating and always resisting the round rod 402c-2.

[0067] The limiting assembly 403 includes a shaking member 403a disposed on the inner wall of the tank body 301 and a guide member 403b disposed between the guide plate 302c and the tank body 301. When the driving unit 401 pushes the movable cylinder 302a, the guide member 403b limits the movable cylinder 302a. The tank body 301 is movably connected to the movable cylinder 302a via the shaking member 403a. The movable cylinder 302a is guided by the shaking member 403a during both the upward and rotational processes.

[0068] The shaking member 403a includes a fixed cylinder 403a-1 fixed on the inner wall of the tank body 301, a reciprocating groove 403a-2 provided on the fixed cylinder 403a-1, and a fixed column 403a-3 provided on the outside of the moving cylinder 302a; wherein the fixed cylinder 403a-1 is sleeved with the moving cylinder 302a, the fixed cylinder 403a-1 extends into the reciprocating groove 403a-2, the fixed cylinder 403a-1 is located above the pushing assembly 402, and the fixed cylinder 403a -1 has multiple sets of reciprocating grooves 403a-2, each of which has a longitudinal section Y1, a sliding section Y2, a shaking section Y3, and an oblique arc section Y4. The shaking section Y3 has multiple sets of oblique teeth. Multiple sets of fixed columns 403a-3 are fixed to the outside of the movable cylinder 302a, and the number of fixed columns 403a-3 corresponds to the number of reciprocating grooves 403a-2. The reciprocating spring 402b can push the reciprocating groove 403a-2 to a length greater than or equal to the length of the sliding section Y2.

[0069] The driving part 401 pushes the moving cylinder 302a to rise, causing the fixed column 403a-3 to slide in the longitudinal section Y1 of the reciprocating groove 403a-2. The guide member 403b prevents the fixed column 403a-3 from entering the oblique arc section Y4. At this time, the reciprocating spring 402b is in a compressed state. When the fixed column 403a-3 rises to correspond to the sliding section Y2, the reciprocating spring 402b pushes the fixed column 403a-3 to move in the sliding section Y2 by contacting with the round rod 402c-2, causing the moving cylinder 302a to rotate in the first direction. When the fixed column 403a-3 moves to correspond to the shaking section Y3, the moving cylinder 302a falls due to its own weight. During the falling process, the fixed column 403a-3 and the shaking section The contact with the inner wall of Y3 causes the movable cylinder 302a to shake, thereby causing the screen 302b to screen the coal blocks. The fixed column 403a-3 enters the oblique arc section Y4 from the shaking section Y3. The slope of the oblique arc section Y4 guides it, causing the fixed column 403a-3 to slide back to the longitudinal section Y1. When the fixed column 403a-3 gradually moves from the shaking section Y3 to the longitudinal section Y1, the movable cylinder 302a rotates in the second direction, thereby causing the round rod 402c-2 to squeeze the reciprocating spring 402b through the cross bar 402c-1. When the fixed column 403a-3 completely falls into the longitudinal section Y1, the movable cylinder 302a stops moving. When the driving unit 401 pushes the movable cylinder 302a again, the movable cylinder 302a repeats the above action.

[0070] The guide member 403b includes a side block 403b-1 fixedly arranged on the inner wall of the tank body 301 below the round rod 402c-2, a limiting post 403b-2 slidably arranged in the round rod 402c-2, and a circular groove 403b-3 provided on the side block 403b-1; wherein the circular groove 403b-3 corresponds to the limiting post 403b-2, the limiting post 403b-2 can slide in the round rod 402c-2, and a limiting groove is provided in the round rod 402c-2 to match the limiting post 403b-2. With the circular groove 403b-3 as the dividing line, the side block 403b-1 is close to one end of the oblique arc segment Y4. It is wider than the other end. When the movable cylinder 302a rises, the limiting column 403b-2 is located in the circular groove 403b-3 to limit it, preventing the fixed column 403a-3 from sliding into the oblique arc segment Y4. When the movable cylinder 302a falls into the oblique arc segment Y4, the limiting column 403b-2 is located above the side block 403b-1 and gradually contacts it and retracts into the round rod 402c-2. When the fixed column 403a-3 returns to the longitudinal segment Y1, the limiting column 403b-2 falls due to its own weight and is plugged into the circular groove 403b-3. The length of the limiting column 403b-2 is longer than the connection between the longitudinal segment Y1 and the oblique arc segment Y4.

[0071] The screening component 300 is provided with a material passing component 500 , which cooperates with the moving component 400 .

[0072] The material passing component 500 includes a fixed bucket 501 fixed on the fixed cylinder 403a-1, and a plurality of groups of protrusions 502 are fixedly provided at the bottom of the fixed bucket 501, wherein the movable cylinder 302a can be connected with the fixed bucket 501, the edge of the fixed bucket 501 is inclined inward, and the bottom of the fixed bucket 501 is parallel to the surface of the screen 302b. When the movable cylinder 302a rises, the screen 302b and the bottom of the fixed bucket 501 cooperate to squeeze the material, so that the material remaining above the screen 302b is crushed. When the movable cylinder 302a rotates, the protrusions 502 cooperate with the screen 302b to crush the material, so that it is further crushed.

[0073] The moving part 503 includes a thin rod 503b fixed at the center position of the screen 302b and a thin rod 503b provided at the bottom of the cylindrical part 503a; wherein, the cylindrical part 503a is plugged into the fixed bucket 501, and a cylindrical part 503a is fixed on the top of the thin rod 503b, and the cylindrical part 503a is plugged into the fixed bucket 501. When the screen 302b rises, the cylindrical part 503a gradually separates from the fixed bucket 501. When the fixed column 403a-3 moves in the sliding section Y2, the cylindrical part 503a is completely separated from the fixed bucket 501, and the material falls onto the screen 302b through the gap between the thin rod 503b and the fixed bucket 501. When the moving cylinder 302a falls, the cylindrical part 503a is plugged into the fixed bucket 501 again.

[0074] The rest of the structure is the same as that of Example 2.

[0075] Operation process: The coal blocks fall between the two sets of rotating plates 201, and the driving motor 102a drives the two sets of crushing rollers 102b to rotate in opposite directions. At the same time, the driving motor 102a drives the rotating shaft 203a to rotate through the synchronous wheel set 203c, and the rotating shaft 203a drives the cam 203b to rotate. During the rotation process, the cam 203b alternately conflicts with the upper and lower cross plates 202c, and then drives the rack 202b to slide back and forth. The rack 202b reciprocates and drives the fan-shaped toothed plate 202a to rotate back and forth, so that the two sets of rotating plates 201 intermittently squeeze the coal blocks, and the coal blocks are initially crushed. The coal blocks that reach a certain particle size fall between the two sets of crushing rollers 102b, and the two sets of crushing rollers 102b further crush them. The crushing efficiency is improved by multiple crushing of the coal blocks.

[0076] The crushed coal blocks are guided by the guide hopper 101b into the tank body 301, and the coal blocks fall on the fixed bucket 501, and then fall on the screen 302b after passing through the fixed bucket 501. The driving part 401 pushes the movable cylinder 302a to rise, and the screen 302b is driven to gradually approach the bottom of the fixed bucket 501, squeezing and crushing the coal blocks on the screen 302b. The fixed column 403a-3 rises along the longitudinal section Y1, and the cylindrical part 503a gradually separates from the fixed bucket 501. The limiting column 403b-2 is plugged into the side block 403b-1 to prevent the fixed column 403a-3 from entering the oblique arc section Y4. When the fixed column 403a-3 slides over the oblique arc section Y4, the limiting column 403b-2 is separated from the side block 403b-1. When the fixed column 403a-3 When the a-3 moves to correspond to the sliding section Y2, the reciprocating spring 402b pushes the moving cylinder 302a to rotate in the first direction through the stopper 402c. At this time, the fixed column 403a-3 moves in the sliding section Y2, and the cylindrical member 503a completely separates from the fixed bucket 501. The coal blocks fall onto the screen 302b through the gap between the thin rod 503b and the fixed bucket 501, and the protrusions 502 cooperate with the screen 302b to further crush the coal blocks. When the fixed column 403a-3 moves to correspond to the shaking section Y3, the moving cylinder 302a falls due to its own weight, and then drives the fixed column 403a-3 to move in the shaking section Y3. The fixed column 403a-3 contacts the inner wall of the shaking section Y3, causing the moving cylinder 302a to move. 02a vibrates, and then completes the material screening. Since the moving cylinder 302a is connected with the fixed bucket 501, the shaking of the moving cylinder 302a makes the material on the fixed bucket 501 fall better on the screen 302b. In the process of the fixed column 403a-3 entering the oblique arc section Y4 from the shaking section Y3, the cylindrical part 503a is driven to fall and plug into the fixed bucket 501, and the coal blocks stop falling on the screen 302b. After the fixed column 403a-3 enters the oblique arc section Y4 from the shaking section Y3, the moving cylinder 302a rotates in the second direction along the oblique arc section Y4. At this time, the limiting column 403b-2 is located above the side block 403b-1 and gradually contacts the side block 403b-1. When the fixed column 403a-3 moves to the longitudinal section Y1 When the moving cylinder 302a is fully reset, the driving unit 401 pushes the moving cylinder 302a to rise again. The material in the moving cylinder 302a is shaken and screened by the reciprocating rise and fall of the moving cylinder 302a, and the material remaining on the screen 302b is automatically crushed by the setting of the fixed bucket 501. There is no need to take out the material on the screen 302b and crush it, thereby improving the screening efficiency. The material in the fixed bucket 501 intermittently falls on the screen 302b through the reciprocating rise and fall of the moving unit 503, so that the material can be fully screened and crushed, and the screened material is discharged from the discharge port.
