[0019] 4. The present invention causes the breaker hammer to reciprocate while the high-pressure fluctuating airflow is discharged. The high-pressure fluctuating airflow cleans the bottom of the breaker hammer when passing through the breaker hammer along the inclined surface of the screen plate. When the breaker hammer reciprocates, it collides with the screen plate to generate vibration, which further cleans the bottom of the breaker hammer and the screen plate.

[0030] The outer movable sleeve of the eccentric rod 705 is provided with a rotating plate 706, and the end of the rotating plate 706 away from the eccentric rod 705 is rotatably connected to a rotating seat 708 through a rotating shaft 707.

[0031] Specifically, when the raw materials in the material hopper 2 are discharged onto the drop table 6 through the guide hopper 5, the hammer motor 703 is used to drive the rotating disk 704 to rotate, and the rotating seat 708 and the guide column 709 are driven to move up and down through the rotating plate 706. The guide column 709 drives the breaker 710 to move up and down. When the breaker 710 moves downward to the bottom, it hammers and breaks the raw materials in the drop table 6.

[0032] The crushing assembly 8 includes a side frame 801 and two crushing rollers 807 that cooperate with each other. The side frame 801 is arranged on the outside of the crusher box 1. A crushing motor 802 is arranged on the side frame 801. The output shaft of the crushing motor 802 is fixedly connected to a main pulley 803. A secondary pulley 805 is arranged on the upper side of the main pulley 803. The main pulley 803 and the secondary pulley 805 are connected through a belt 804.

[0033] A mounting shaft is provided in the middle of the two crushing rollers 807, and one end of the two mounting shafts is fixedly sleeved with a transmission gear 806. The two transmission gears 806 are meshed with each other. The end of one of the mounting shafts is fixedly connected to the secondary pulley 805, and the two mounting shafts are horizontally rotatably connected to the inside of the crusher box 1.

[0034] Specifically, when the raw material falls between the two crushing rollers 807, the crushing motor 802 is used to drive one of the crushing rollers 807 to rotate through the main pulley 803, the secondary pulley 805 and the belt 804, and the crushing rollers 807 on both sides are rotated in opposite directions through two mutually meshing transmission gears 806, so as to squeeze and crush the raw material passing through the two crushing rollers 807, realize secondary crushing, and the material enters the grinding equipment 9 for grinding after passing through the crushing roller 807.

[0035] When in use, the raw materials are put into the feed hopper 3, and the driving motor 402 is started to rotate the two sprockets 403 through the toothed belt 404 and synchronously drive the rotating shaft 406 and the transmission rod 408 to rotate. The rotation of the guide vane 407 is used to stir and guide the raw materials in the feed hopper 3 to avoid blockage of the raw materials. After the raw materials enter the interior of the leveling hopper 2 from the feed hopper 3, the transmission rod 408 drives the worm 409 to rotate, so that the worm wheel 410 drives the mounting rod 411 and the fixed rod 412 to rotate at the same time, and the fixed rod 412 drives multiple leveling plates 413 to rotate, and the materials fill the space between the two adjacent leveling plates 413 in turn, and the raw materials entering the leveling hopper 2 are evenly separated, and the materials are evenly dropped in batches when the leveling plates 413 rotate.

[0036] After the raw materials are discharged through the material leveling hopper 2, they are discharged to the material drop platform 6 by the guide hopper 5. The hammer motor 703 is started to rotate the rotating disk 704. The rotating disk 704 causes the rotating plate 706 to drive the rotating seat 708 to reciprocate up and down. When the material passes through the bottom of the crushing hammer 710, the crushing hammer 710 uses the downward movement to hammer and crush the material, thereby realizing the primary pre-crushing of the raw materials. Then the raw materials fall on the two crushing rollers 807, and the crushing motor 802 is started. The crushing motor 802 drives the main pulley 803 to rotate and uses the belt 804 to make the secondary pulley 805 rotate synchronously. Since the two transmission gears 806 are meshed, the two crushing rollers 807 can rotate in opposite directions. When the raw materials pass between the crushing rollers 807, the crushing teeth are used to perform secondary crushing.

[0037] However, when the material after being hammered by the hammer assembly 7 is discharged along the drop table 6 to the crushing roller 807, since the discharge position of the material is fixed, the material will accumulate between the two crushing rollers 807 and cannot be evenly dispersed along the axial direction of the crushing roller 807, resulting in low crushing efficiency. Therefore, the following improvements are made: The material dropping platform 6 includes a sieve plate 601 and an electric slide rail 602. The sieve plate 601 is tilted on the inner side of the material dropping platform 6. The breaker 710 is equal to and parallel to the sieve plate 601 in width. The electric slide rail 602 is arranged on the top inclined surface of the material dropping platform 6. The top inclined surface of the material dropping platform 6 is parallel to the sieve plate 601. The setting of the electric slide rail 602 realizes the movement of the hammering assembly 7. The sieve plate 601 is used to screen the material after hammering, and the material with qualified particle size falls through the sieve holes of the sieve plate 601.

[0038] When in use, in the initial state, the breaker hammer 710 is located at the top of the material drop platform 6. When the material is discharged from the guide hopper 5, the electric slide rail 602 is started to drive the guide frame 701 to move to the bottom of the material drop platform 6. At the same time, the hammer motor 703 is started to make the breaker hammer 710 reciprocate to hammer the material. When the material moves along the inclined surface of the material drop platform 6, the breaker hammer 710 also moves toward the bottom of the material drop platform 6. At this time, the reciprocating motion frequency of the breaker hammer 710 and the downward moving speed are sufficient to ensure that the material is hammered at least once before completely passing through the breaker hammer 710.

[0039] After being hammered and crushed, the material falls through the sieve holes of the sieve plate 601 after the particle size meets the requirements, and as the material and the crushing hammer 710 move obliquely downward, the material with the qualified particle size is evenly distributed along the axial direction of the crushing roller 807, preventing the material from piling up at the fixed position on the top of the crushing roller 807 and affecting the crushing efficiency. The material with the unqualified particle size is reset again to the top of the drop table 6 as the bottom of the crushing hammer 710 moves obliquely upward against the sieve plate 601, and is crushed together with the next batch of materials to fully crush the material.

[0040] It should be noted that, under the action of the guiding component 4, the materials fall onto the drop table 6 in quantitative batches, and there is a gap between each batch. The time interval after each batch completes the drop is sufficient to allow the breaker 710 to move downward to the bottom of the drop table 6 and reset to the top of the initial state. The above operation can be repeated after the next batch of materials is discharged.

[0041] In addition, after crushing, the sieve holes of the sieve plate 601 will be clogged with materials, and the bottom crushing surface of the breaker 710 and the crushing roller 807 will also be adhered with residues and debris, which will affect the crushing accuracy and be inconvenient to clean. In order to solve the above problems: The guide blades 407 are arranged in an inclined manner in the shape of fan blades.

[0042] The material guide hopper 5 includes an elastic cover 501 and a material blanking frame 502 . The elastic cover 501 is arranged between the material leveling hopper 2 and the material blanking frame 502 . The elastic cover 501 is made of rubber. The setting of the elastic cover 501 provides conditions for the movement of the material blanking frame 502 .

[0043] A locking mechanism is provided between the guide frame 701 and the blanking frame 502. The sliding portion of the electric slide rail 602 is fixedly connected to the bottom of the guide frame 701. The setting of the locking mechanism enables a detachable connection between the blanking frame 502 and the guide frame 701 when the guide frame 701 moves to the position of the blanking frame 502.

[0044] After use is completed and there is no material in the feed hopper 3 and the material leveling hopper 2, the drive motor 402 is started to make the guide blade 407 and the material leveling plate 413 idle. When the guide blade 407 rotates, due to the fan-shaped inclined setting, a downward airflow is generated. At the same time, the rotation of the material leveling plate 413 realizes the intermittent opening and closing of the bottom port of the material leveling hopper 2, so that intermittent fluctuating high-pressure airflow is discharged from the bottom of the material leveling hopper 2. The high-pressure airflow passes through the guide hopper 5 and is discharged to the top of the sieve plate 601. At the same time, when the guide frame 701 is located at the top of the blanking platform 6, the locking mechanism is used to lock the guide frame 701 and the blanking frame 502, and the electric slide rail 602 is used to drive the guide frame 701 to move obliquely downward, and the guide frame 701 drives the blanking frame 502 to move The elastic cover 501 is gradually stretched, and the high-pressure fluctuating airflow discharged from the blanking frame 502 cleans the residue and debris blocked in the screen plate 601 while moving obliquely downward. At the same time, the hammer motor 703 is started to make the breaker 710 reciprocate. The high-pressure fluctuating airflow cleans the residue and debris attached to the bottom of the breaker 710 when passing through the bottom of the breaker 710, and collides with the screen plate 601 when the breaker 710 moves downward to generate vibration, further improving the cleaning effect of the breaker 710 and the screen plate 601, and the high-pressure fluctuating airflow passes through the screen plate 601 when the blanking frame 502 moves, and blows toward the crushing roller 807, so that the residue and debris on the crushing roller 807 are cleaned by rotating the crushing roller 807.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
