[0023] Specifically, the dust collecting device 3 includes a fixed frame 31, an inclined net 32, a closing component 33, a fan 35, a filter cloth 36 and a connecting box 38. The fixed frame 31 is installed above the feed barrel 2, the inclined net 32 ​​is installed on the inner side of the fixed frame 31 and at a position obliquely above the feed barrel 2, the connecting box 38 is installed below the fixed frame 31 and at a position on one side of the crushing box 1, a plurality of fans 35 are installed below the connecting box 38, the filter cloth 36 is installed on the inner side of the connecting box 38, and the closing component 33 is installed on one side of the fixed frame 31 near the edge.

[0024] By adopting the above technical solution, the device can separate and collect dust in the waste when necessary through the cooperation of structures such as the fan 35 and the inclined net 32, thereby reducing the possibility of dust flying during the recycling and classification process and ensuring effective dust recovery.

[0025] Specifically, the dust collecting device 3 further includes a threaded block 34 and a vibrator 37 . The threaded block 34 is installed on the side of the connecting box 38 away from the crushing box 1 through threads, and two vibrators 37 are installed below the filter cloth 36 .

[0026] By adopting the above technical solution, the staff can unscrew the threaded block 34 to remove the dust in the connection box 38 when necessary, and the device can drive the filter cloth 36 to vibrate through the vibrator 37 when necessary, so as to prevent the filter cloth 36 from being blocked.

[0027] Specifically, the closing assembly 33 includes an electric telescopic rod 331 and an L-shaped plate 332 . The electric telescopic rod 331 is installed on one side of the fixed frame 31 , and the L-shaped plate 332 is installed on the outer side of the electric telescopic rod 331 and above the connection box 38 .

[0028] By adopting the above technical solution, the device can close the connection box 38 through the cooperation of the electric telescopic rod 331 and the L-shaped plate 332 when necessary, thereby preventing liquid from entering the connection box 38 when the waste contains liquid.

[0029] When the present embodiment is used, when the device is needed for recycling and sorting in a construction project, the worker pushes the device and moves the device to the working position through the universal wheels 8, and then starts the electric telescopic rod 331 in the closed component 33 of the dust collecting device 3, thereby driving the L-shaped plate 332 to move, so that the connecting box 38 is no longer closed, and the waste is poured from the top of the inclined net 32 ​​in the fixed frame 31.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the buffer fixing device 5 includes a connecting frame 51, an elastic rubber frame 52, a damper 53 and a bottom plate 54; the connecting frame 51 is installed on the side of the filtering and sorting component 6 close to the multiple universal wheels 8; the bottom plate 54 is installed above the multiple universal wheels 8 and at a position located on the inner side of the connecting frame 51; the elastic rubber frame 52 is installed between the inner top surface of the connecting frame 51 and the outer top surface of the bottom plate 54; and multiple dampers 53 are installed between the inner top surface of the connecting frame 51 and the outer top surface of the bottom plate 54 and at a position located on the inner side of the elastic rubber frame 52.

[0032] By adopting the above technical solution, the device can buffer external vibrations to a certain extent through the cooperation of structures such as the elastic rubber frame 52 and the damper 53, thereby reducing the possibility that the recycling and sorting work is adversely affected by external vibrations.

[0033] Specifically, the buffer fixing device 5 also includes an insert cone 55, a connecting plate 56 and an electric lifting rod 57. The electric lifting rods 57 are installed on both sides of the connecting frame 51. The connecting plate 56 is installed below the electric lifting rod 57, and multiple insert cones 55 are installed below the connecting plate 56.

[0034] By adopting the above technical solution, the device can, when necessary, perform auxiliary fixation on its own position through the cooperation of structures such as the insert cone 55 and the electric lifting rod 57, thereby reducing the possibility of accidental movement of the device due to external collisions and the like.

[0035] When this embodiment is used, during operation, the elastic rubber frame 52 and the damper 53 between the inner top surface of the connecting frame 51 and the outer top surface of the bottom plate 54 in the buffer fixing device 5 can buffer external vibrations to a certain extent, thereby reducing the possibility that the recycling and sorting work is adversely affected by external vibrations. When it is necessary to assist in fixing the position of the device, the two electric lifting rods 57 are started to drive the two connecting plates 56 to descend until each cone 55 is inserted into the ground, thereby assisting in fixing the position of the device, thereby reducing the possibility of accidental movement of the device due to external collisions and the like.

[0036] The structures and principles of the crushing box 1, the collecting box 4, the filtering and sorting assembly 6 composed of a support seat, a filter plate, a mounting plate, a second motor, an eccentric wheel, a connecting plate, a connecting rod, a fixing rod, a spring and an electromagnet, and the crushing knife assembly 7 composed of a first motor, a fixing block, a rotating shaft and a crushing knife in the utility model have been disclosed in the waste recycling and sorting device for demolition construction disclosed in Chinese patent application No. 201920935023.X. The working principle is that the first motor is controlled by the first controller, the first controller model is BS216B, the first motor, the first controller and the external power supply are electrically connected in sequence through wires to form a closed loop; the second motor is controlled by the second controller, the second controller model is BS230B, the second motor, the second controller and the external power supply are electrically connected in sequence through wires to form a closed loop; first, when the waste is recycled and sorted, the first controller is turned on, the first motor is started, and as the first motor is started, the rotating shaft is driven to rotate by the output shaft of the first motor; as the rotating shaft rotates, the crushing knife is driven to rotate by the rotating shaft, and at this time, the feed inlet at the top of the crushing box is fed in. The waste material can be crushed. After the crushing is completed, the crushed waste material will move downward through the discharge port. The iron filings in the crushed waste material can be collected by the electromagnet, and the non-iron waste material falls on the filter plate; at the same time, the second controller is turned on, the second motor is started, and the output shaft of the second motor drives the eccentric wheel to rotate. As the eccentric wheel rotates, the eccentric wheel pushes the connecting plate to move; as the connecting plate moves, the two connecting rods will drive the filter plate to slide on the two support seats, and at the same time, as the connecting plate moves, the spring will be squeezed by the connecting plate; as the eccentric wheel rotates to 180 degrees, the filter plate moves the farthest to the left. When the eccentric wheel continues to rotate, the filter plate moves to the right under the elastic action of the spring. When the eccentric wheel rotates to 360 degrees, the filter plate moves the farthest to the right; through the continuous rotation of the eccentric wheel, the filter plate can be reciprocated, so that the crushed waste material is filtered faster, and impurities can be filtered through the filter plate, so that the filtered waste material falls into the collection box; iron filings can be collected by the electromagnet, and impurities can be filtered through the filter plate, which can effectively carry out waste recycling and classification.

[0037] The structure and principle of the vibrator 37 in the utility model have been disclosed in an easy-to-clean concrete mixing device disclosed in Chinese Patent Application No. 201821054815.8. Its working principle is composed of components such as springs, mass blocks, and motors. When the spring or mass block is subjected to external force from the motor, elastic deformation or displacement will occur, thereby generating vibration.

[0038] The structure and principle of the damper 53 in the utility model have been disclosed in a smart home washing machine shock absorbing device disclosed in Chinese patent application No. 201721446985.6. Its working principle consists of a piston and an oil tank, which is filled with oil. When the object moves, the piston moves in the oil, thereby consuming energy and slowing down the movement of the object.

[0039] The working principle and use process of the utility model are as follows: when the device is needed for recycling and sorting in a construction project, the staff pushes the device and moves the device to the working position through the universal wheels 8, and then starts the electric telescopic rod 331 in the closed component 33 of the dust collecting device 3, thereby driving the L-shaped plate 332 to move, so that the connecting box 38 is no longer closed, and the waste begins to be poured from the top of the inclined net 32 ​​in the fixed frame 31. The waste slides along the inclined net 32 ​​and starts each fan 35. Under the action of each fan 35, the dust in the waste passes through the inclined net 32 ​​and is sucked into the connecting box 38, and is then blocked by the filter cloth 36. The staff can start the two vibrators 37 to drive the filter cloth 36 to vibrate to prevent the filter cloth 36 from being blocked, and then the remaining waste passes through the feed barrel 2 into the crushing box 1, and the crushing knife component 7 is started to crush the waste. The crushed waste arrives at the filtering and sorting component 6, The filtering and sorting component 6 is operated to process the waste, a part of the waste is intercepted by the filtering and sorting component 6, and the other part falls into the collecting box 4, and then the staff closes each structure, unscrews the threaded block 34 to take out the dust in the connecting box 38, removes the collecting box 4 and the waste in it, and then removes the waste intercepted by the filtering and sorting component 6, and the recycling and sorting work is completed; when working, the elastic rubber frame 52 and the damper 53 between the inner top surface of the connecting frame 51 and the outer top surface of the bottom plate 54 in the buffer fixing device 5 can buffer the external vibration to a certain extent, thereby reducing the possibility that the recycling and sorting work is adversely affected by the external vibration. When it is necessary to assist in fixing the position of the device, the two electric lifting rods 57 are started, thereby driving the two connecting plates 56 to descend until each cone 55 is inserted into the ground, thereby assisting in fixing the position of the device, thereby reducing the possibility of accidental movement of the device due to external collision and the like.
