However, the structure of the crushing component contained in the equipment is relatively simple, the material handling capacity is poor, and the small materials after crushing are mostly in a state of mutual entanglement, and the size of the small materials after crushing varies.

Two associated frames 515 are fixedly installed on the bottom of the second rectangular cover 502, and a third rectangular cover 516 is fixedly installed between the bottoms of the two associated frames 515. Two linkage rods 517 are movably inserted between the two sides of the inner wall of the third rectangular cover 516, and the outer wall of each linkage rod 517 is fixedly sleeved with a crushing roller rod 518. A gathering funnel 525 is fixedly installed at the bottom of the third rectangular cover 516.

[0024] according to Figure 5 and Figure 6 As shown, a U-shaped bracket 512 is fixedly installed between the two sides of the outer wall of each first limiting protective shell 503, and a first positioning seat 513 is fixedly installed on the outer wall of each U-shaped bracket 512. A hydraulic push rod 514 is fixedly inserted inside each first positioning seat 513, and the axial end of each hydraulic push rod 514 is respectively fixedly inserted inside a corresponding solid plate 506. By presetting the above-mentioned components and utilizing the movable connectivity of the translation slide 504 and the T-shaped rail 505, when each group of hydraulic push rods 514 is turned on, the two relative hydraulic push rods 514 can operate synchronously, so as to drive the connected solid plates 506 to move inside the first rectangular cover 501 and the second rectangular cover 502, and successively perform shape-breaking processing on plate materials of different degrees.

[0025] according to Figure 5 and Figure 6As shown, a first external frame 519 is fixedly installed on the front surface of the second rectangular cover 502, a load-bearing support plate 520 is welded to the bottom of the first external frame 519, a servo motor 521 is fixedly installed on the outer wall of the load-bearing support plate 520, an active roller 522 is fixedly sleeved on the output end of each servo motor 521, a secondary roller 523 is fixedly sleeved on one end of the outer wall of each linkage rod 517, a traction belt 524 is movably sleeved between the outer walls of each active roller 522 and the secondary roller 523, by presetting the above components, the mechanism completes power transmission by belt traction, drives the two crushing rollers 518 to roll relative to each other, and maximizes the crushing of the pre-treated plate into a small volume.

[0026] according to Figure 5 and Figure 6 As shown, a group of second limiting protective shells 526 are fixedly installed inside each U-shaped bracket 512, and a synchronization rod 527 is movably inserted inside each second limiting protective shell 526. One end of the outer wall of each group of synchronization rods 527 is fixedly inserted inside a corresponding solid plate 506. By presetting the above components, when each solid plate 506 moves inside the first limiting protective shell 503, the corresponding group of synchronization rods 527 can also slide synchronously inside the second limiting protective shell 526, so as to further limit the initial position of each solid plate 506 and ensure the stability of the plate when it is broken.

[0027] according to Figure 2 , Figure 7 and Figure 8 As shown, the adsorption dust removal mechanism 6 includes an intersection box 601, which is fixedly installed inside the hollow frame 3, and a group of diversion pipes 602 are fixedly connected to the front surface of the intersection box 601. A second external frame 603 is fixedly installed on one side of the outer wall of the square tube 7, and an induction component 604 is provided on the top of the second external frame 603. The input end of the induction component 604 is fixedly connected to a group of air guide pipes 608, and the air inlet ends of a group of air guide pipes 608 all pass through the top of the intersection box 601 and are connected to the interior of the intersection box 601. By presetting the above components, the mechanism adopts a reverse exhaust method. When the mechanical components are running, the air inlet end of each diversion pipe 602 has a strong adsorption force, and continuously extracts the air in the external protective shell 1 and the dust generated by the crushed plate.

[0028] according to Figure 7As shown, a wiring sealing plate 605 is fixedly installed on the rear surface of the intersection box 601, and a group of second positioning seats 606 are fixedly installed on the front surface of the wiring sealing plate 605, and the number of a group of second positioning seats 606 is equal to a group of diversion pipes 602, and an electrostatic adsorption rod 607 is fixedly inserted inside each second positioning seat 606, and each electrostatic adsorption rod 607 is respectively placed inside a corresponding diversion pipe 602. By presetting the above components, when each electrostatic adsorption rod 607 is energized, an electric field will continue to be formed in the corresponding diversion pipe 602, forcing the uncharged dust entering the diversion pipe 602 to combine with positive and negative electrons, and then the electrostatic adsorption rod 607 completes the adsorption of charged dust.

[0029] according to Figure 7 As shown, a group of wiring bases 609 are fixedly installed on the rear surface of the wiring sealing plate 605, and the number of a group of wiring bases 609 is equal to a group of flow pipes 602. The output end of each wiring base 609 is respectively connected to a corresponding electrostatic adsorption rod 607, and the wiring end of each wiring base 609 is fixedly connected to a group of second wires 612, and the input end of each group of second wires 612 is connected to the internal wiring of the wiring sealing plate 605.

[0030] according to Figure 7 and Figure 8 As shown, an independent power supply 610 is fixedly installed at the bottom of the junction box 601, and a group of first wires 611 are fixedly connected to the wiring terminals of the independent power supply 610. The output ends of the group of first wires 611 are all connected to the internal wiring of the wiring cover 605. By presetting the above components, the independent power supply 610 can be distinguished from the total power supply of the equipment, thereby ensuring that the energy introduced into the wiring cover 605 is relatively stable, ensuring the dust removal effect of the mechanism, and preventing dust from spreading into the working area of ​​the equipment.

[0031] according to Figure 1 , Figure 2 and Figure 3 As shown, one side of the outer wall of the square tube 7 is fixedly connected to a retention box 8, and a group of electric pushing components 9 are fixedly installed on the outer wall of the retention box 8. A pushing plate 10 is fixedly sleeved between the axial ends of the group of electric pushing components 9, and the pushing plate 10 is movably placed inside the retention box 8. By presetting the above components, this part of the components can temporarily store part of the pre-treated plates, and intermittently complete the plate delivery according to the crushing rate of the equipment.

[0032] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the first rectangular cover 501 is fixedly installed between the opposite sides of the two groups of inner support frames 2, and the third external frames 11 are fixedly installed on both sides of the outer wall of the external protective shell 1. A group of telescopic legs 12 are provided inside the third external frames 11. By presetting the above components, the telescopic legs 12 can be freely raised and lowered to adjust the height of the equipment from the ground, ensuring that the aggregation funnel 525 is at a sufficient distance from the ground to avoid the crushed materials being unable to be collected.

[0033] The effect achieved by the entire mechanism is: first move the equipment to the designated working area, synchronously adjust each telescopic support leg 12, determine the height of the gathering funnel 525 and the ground, ensure that the collection container can be placed at the bottom of the external protective shell 1, and then connect the external line to the main power supply of the equipment and the independent power supply 610 respectively, in order to provide energy for multiple electrical components, and stack a specified number of pre-treated plates according to the size of the retention box 8. After the equipment is started, the two electric push components 9 are synchronously turned on and act on the push plate 10 to slowly push the stacked plates into the square tube 7. When one of the plates enters the square tube 7, it can continue to fall into the external protective shell 1 under its own gravity.

[0034] In the first crushing stage, the two hydraulic push rods 514 are opened synchronously to make their inner shafts reciprocate and extend in the cavity. The movable connection between the translation slide 504 and the T-shaped rail 505 is used to drive the solid plate 506 and its connected parts to move relative to each other, so that the two groups of metal impact blocks 507 continuously impact the plate entering into the first rectangular cover 501. After multiple collisions and impacts, the complete plate is broken into blocks of materials of different sizes. In the process, the material blocks that meet the size of the discharge slot 510 continue to fall into the second rectangular cover 502.

[0035] In the secondary separation stage, through the above method, the corresponding two hydraulic push rods 514 can drive the two connected solid plates 506 to move relative to each other inside the second rectangular cover 502, continuously impacting the large pieces of material that have been initially broken, and utilizing the shape and even distribution characteristics of the second-order breaking cone head 508 to further break up the large pieces of material into multiple small-volume materials. At the same time, the glue in the material will be broken up under the strong impact of each second-order breaking cone head 508, thereby avoiding mutual entanglement between the materials, and the materials that meet the requirements of the discharge circular hole 511 will continue to fall into the third rectangular cover 516.

[0036] In the third-stage crushing stage, the two servo motors 521 are started synchronously, and the rotors of the two servo motors 521 rotate relative to each other, and act on the active roller 522, the secondary roller 523 and the traction belt 524, driving the two crushing rollers 518 to squeeze and rotate inward, completing the final crushing of small pieces of material. The generated granular powdery material gathers in the gathering funnel 525 and is continuously discharged outside the machine and recovered by relevant containers.

[0037] During the dust adsorption stage, when the independent power supply 610 is powered on, the energy in the wiring sealing plate 605 is continuously introduced and transmitted from each wiring base 609 to the corresponding electrostatic adsorption rod 607. Each electrostatic adsorption rod 607 in the powered state will form a strong electric field in each diversion pipe 602. At the same time, the second external frame 603 is turned on to continuously extract the air trapped in the air guide pipe 608, the intersection box 601 and each diversion pipe 602, so that the air inlet end of each diversion pipe 602 has a strong adsorption force, which induces the air flow in the external protective shell 1, and the dust in it will enter each diversion pipe 602 with the air. In the process, after the dust completes electronic bonding, it will be adsorbed to the surface of each electrostatic adsorption rod 607 in turn.
