An observation window 14 is provided on the front side of the processing box 2. A processing mechanism 5 is provided inside the processing box 2. A dustproof mechanism 6 is provided on the feeding box 3.

[0024] Specifically, the magnetic suction plate 10 on the conveyor belt 9 can adsorb the metal waste in the screened construction waste, while the non-metal waste continues to be transported and falls into the non-metal collection box 11. When the magnetic suction plate 10 adsorbing the metal waste is transported to the metal collection box 12, the scraper 13 on the conveyor frame 8 can scrape the metal waste on the magnetic suction plate 10 into the metal collection box 12, thus completing the sorting of construction waste.

[0025] See Figure 2 and Figure 3Furthermore, the processing mechanism 5 includes a crushing trough 501 opened on the processing box 2. Two crushing rollers 502 are rotatably arranged in the crushing trough 501. The roller shafts of the two crushing rollers 502 rotatably pass through the crushing trough 501 and are driven by a gear transmission assembly 503. A support frame 504 is fixedly arranged on the base 1. A motor 505 is fixedly arranged on the support frame 504. Cranks 506 are fixedly arranged on the rotating shaft of the motor 505 and on the roller shaft of one of the crushing rollers 502. A connecting rod 507 is fixedly connected between the two cranks 506. A movable shaft 512 is fixedly arranged in the processing box 2. A screening screen plate 513 is rotatably arranged on the movable shaft 512. A wedge-shaped slide rail 508 is fixedly arranged on the side of the processing box 2 near the motor 505. A wedge block 509 is slidably connected in the wedge-shaped slide rail 508. A fixing rod 510 is fixedly arranged on the wedge block 509. A rotating plate 511 is rotatably sleeved on the fixed rod 510. The other end of the rotating plate 511 is rotatably sleeved on the connecting rod 507. A slider 514 is fixedly installed at one end of the screening screen plate 513. A groove 515 is opened at one end of the processing box 2 and is slidably connected to the slider 514. A sliding rod 516 is fixedly installed in the groove 515 and is slidably connected to the slider 514. A spring 517 is sleeved on the sliding rod 516 and is fixedly installed between the groove 515 and the slider 514. An L-shaped connecting rod 518 is fixedly connected between the fixed rod 510 and the slider 514. The screening screen plate 513 is inclined. The end of the screening screen plate 513 near the movable shaft 512 is the bottom end. A slag collection box 519 is installed below the screening screen plate 513. A slot is opened on the front side of the processing box 2 and is slidably connected to the slag collection box 519. A handle 520 is fixedly installed on the front side of the slag collection box 519.

[0026] Specifically, when the motor 505 rotates, the two cranks 506 drive the connecting rod 507 to rotate. The rotating plate 511 on the connecting rod 507 can drive the wedge block 509 to move up and down along the wedge slide rail 508 through the fixed rod 510. This allows the L-shaped connecting rod 518 connected to the fixed rod 510 to drive the slider 514 to slide up and down in the slide groove 515. The slider 514 slides along the surface of the slide rod 516 in the slide groove 515 and repeatedly squeezes the spring 517, so that the higher end of the screening screen plate 513 can vibrate up and down. This allows the construction waste falling on the screening screen plate 513 to be screened evenly, while effectively preventing the material from clogging the screen holes.

[0027] See Figure 4Furthermore, the dustproof mechanism 6 includes a dustproof cover 601 fixedly installed on the feed box 3. The dustproof cover 601 has an installation groove 602. A bracket 603 is fixedly installed in the installation groove 602. An exhaust fan 604 is fixedly installed on the bracket 603. A dustproof mesh cover 606 is installed below the exhaust fan 604. A dustproof mesh cover 605 is installed above the exhaust fan 604. Both the dustproof mesh cover 606 and the dustproof mesh cover 605 are fixedly installed in the installation groove 602.

[0028] Specifically, the exhaust fan 604 can absorb the dust generated during the crushing of construction waste upwards, and the dustproof mesh cover 606 below the exhaust fan 604 can block impurities in the dust, allowing the exhaust fan 604 to discharge dust-free air upwards, thereby achieving a dust prevention effect and preventing dust from spreading everywhere and polluting the environment and harming the health of workers when the equipment is in use. The dustproof mesh cover 605 installed above the exhaust fan 604 can prevent the exhaust fan 604 from being contaminated by external dust when the equipment is not in use.

[0029] In actual operation, construction waste is poured into the feed box 3, and the motor 505 is started to make the two crushing rollers 502 rotate in opposite directions under the transmission of the gear transmission assembly 503. The construction waste enters the crushing tank 501 through the feed box 3 and is crushed by the two crushing rollers 502. The crushed construction waste falls onto the screening screen plate 513. After screening, the slag passes through the screen holes and falls into the slag collection box 519 for storage. The remaining construction waste is guided by the screening screen plate 513 and falls onto the conveyor belt 9 through the discharge pipe 7. The magnetic suction plate 10 on the conveyor belt 9 can adsorb the metal waste in the construction waste, while the non-metal waste continues to be conveyed and falls into the non-metal collection box 11. When the magnetic suction plate 10 adsorbing the metal waste is conveyed to the metal collection box 12, the scraper 13 on the conveyor frame 8 can scrape the metal waste on the magnetic suction plate 10 into the metal collection box 12, thus completing the sorting of construction waste.

[0030] When the motor 505 rotates, the two cranks 506 drive the connecting rod 507 to rotate. The rotating plate 511 on the connecting rod 507 can drive the wedge block 509 to move up and down along the wedge slide rail 508 through the fixed rod 510. This allows the L-shaped connecting rod 518 connected to the fixed rod 510 to drive the slider 514 to slide up and down in the slide groove 515. The slider 514 slides along the surface of the slide rod 516 in the slide groove 515 and repeatedly squeezes the spring 517, so that the higher end of the screening screen plate 513 can vibrate up and down. This allows the construction waste falling on the screening screen plate 513 to be screened evenly, while effectively preventing the material from clogging the screen holes.

[0031] When construction waste is being crushed, the exhaust fan 604 can draw the dust generated during the crushing process upwards. The dustproof mesh cover 606 below the exhaust fan 604 can block impurities in the dust, allowing the exhaust fan 604 to discharge dust-free air upwards, thereby achieving a dustproof effect and preventing dust from spreading everywhere and polluting the environment and harming the health of workers when the equipment is in use. The dustproof mesh cover 605 installed above the exhaust fan 604 can prevent the exhaust fan 604 from being contaminated by external dust when the equipment is not in use.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
