Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] Reference Figures 1-4 The present invention provides a construction waste crushing device, comprising:

[0044] The housing 1 is equipped with a feed inlet 2, a first discharge outlet 3 and a second discharge outlet 4;

[0045] A pair of crushing rollers 5 are installed inside the housing 1, and the pair of crushing rollers 5 are located directly below the feed inlet 2;

[0046] A pair of cleaning rollers 6 are disposed inside the housing 1, with the pair of cleaning rollers 6 located on both sides of a pair of crushing rollers 5;

[0047] The filter screen 7 is inclinedly installed inside the housing 1. The filter screen 7 is located between the crushing roller 5 and the first discharge port 3, and the lower end of the filter screen 7 is close to the second discharge port 4.

[0048] The first drive mechanism is mounted on the housing 1 and is used to drive a pair of crushing rollers 5 to rotate relative to each other.

[0049] The second drive mechanism is set on the housing 1. The second drive mechanism is used to drive a pair of crushing rollers 5 to move closer or further apart, so that the crushing rollers 5 can abut against the cleaning rollers 6.

[0050] The third drive mechanism is located inside the housing 1. The third drive mechanism is used to drive the filter screen 7 to rise, fall and vibrate.

[0051] Construction waste is fed into the housing 1 through the feed inlet 2. The first drive mechanism drives a pair of crushing rollers 5 to rotate and perform crushing operations. The crushed aggregate that meets the specifications is screened by the filter screen 7 and discharged through the first discharge outlet 3. When the pair of crushing rollers 5 become clogged or have too much waste stuck to them, the second drive mechanism drives the pair of crushing rollers 5 to move away from each other, increasing the gap between them. This allows large pieces of stuck waste to fall onto the filter screen 7. When the crushing rollers 5 come into contact with the cleaning rollers 6, the first drive mechanism drives the pair of crushing rollers 5 to rotate, so that the cleaning rollers 6 clean the crushing rollers 5, removing the impurities stuck to them. Then, the pair of crushing rollers 5 are reset and the crushing operation is quickly resumed. No machine downtime or manual maintenance is required, which improves production safety, makes cleaning convenient, shortens maintenance time, and improves crushing efficiency.

[0052] Furthermore, the crushing roller 5 includes a roller body and bristles made of nylon or steel wire disposed on the roller body.

[0053] In one embodiment of the present invention, a pair of sliding grooves 8 are provided on the side wall of the box body 1, and the two ends of the crushing roller 5 are respectively rotatably connected to the first slider 9 which is slidably fitted in the pair of sliding grooves 8.

[0054] When a pair of crushing rollers 5 slide, sliding support for the crushing rollers 5 is achieved by the first slider 9 sliding along the sliding normal 8.

[0055] Furthermore, a limiting groove is formed in the sliding groove 8, and multiple limiting sliders are slidably fitted in the limiting groove. The limiting sliders are fixedly connected to the first slider 9 and the second slider 24 to achieve guiding and limiting of the first slider 9 and the second slider 24.

[0056] In one embodiment of the present invention, the first driving mechanism includes:

[0057] Motor 10 is mounted on the outer wall of housing 1;

[0058] A pair of driven pulleys 11 are arranged on both sides of the motor 10. One driven pulley 11 is connected to the shaft of any crushing roller 5, and the other driven pulley 11 is connected to the shaft of another crushing roller 5 through a reversing assembly.

[0059] The driving pulley 12 is located at the output end of the motor 10, and the driving pulley 12 is connected to a pair of driven pulleys 11 by a transmission belt 13.

[0060] The motor 10 drives the active pulley 12 to rotate, which in turn drives a pair of driven pulleys 11 to rotate via the transmission belt 13. The reversing assembly causes a pair of crushing rollers 5 to rotate in opposite directions, effectively improving the crushing effect.

[0061] In one embodiment of the present invention, the reversing component includes:

[0062] Rotating rod 14 is rotatably connected to the first slider 9, and rotating rod 14 is connected to driven pulley 11;

[0063] The first gear 15 is fixedly connected to the rotating rod 14;

[0064] The second gear 16 is fixedly connected to the shaft of the crushing roller 5, and the second gear 16 meshes with the first gear 15.

[0065] Driven pulley 11 drives rotating rod 14 to rotate, thereby driving second gear 16 to rotate through first gear 15 on rotating rod 14, so that crushing roller 5 with second gear 16 rotates in opposite directions to another crushing roller 5.

[0066] In one embodiment of the present invention, the first driving mechanism further includes:

[0067] A pair of fixing plates 17 are fixedly connected to the outer wall of the box body 1;

[0068] A pair of first elastic elements 18 are fixedly connected to a pair of fixed plates 17. The pair of first elastic elements 18 are located on both sides of the motor 10. The telescopic end of the first elastic element 18 is fixedly connected to a first bearing seat 19. A connecting rod 21 with a tension wheel 20 is rotatably connected to the first bearing seat 19. The tension wheel 20 abuts against the transmission belt 13.

[0069] As the pair of crushing rollers 5 move, the drive belt 13 deforms, and the first elastic element 18 and the tensioning wheel 20 enable the drive belt 13 to maintain a drive connection with the pair of driven pulleys 11.

[0070] In one embodiment of the present invention, the second driving mechanism includes:

[0071] A double-outlet cylinder 22 is installed on the outer wall of the housing 1. The two output ends of the double-outlet cylinder 22 are respectively fixedly connected to the second bearing seats 23. The pair of second bearing seats 23 correspond to and are rotatably connected to the shafts of the pair of crushing rollers 5.

[0072] The second bearing seat 23 is pushed by the double-outlet cylinder 22, thereby driving the crushing roller 5 to move.

[0073] In one embodiment of the present invention, the two ends of the cleaning roller 6 are respectively fixedly connected to the second slider 24, the second slider 24 is slidably connected in the sliding groove 8, and the second elastic member 25 is fixedly connected between the second slider 24 and the end face of the sliding groove 8. The end of the first slider 9 near the second slider 24 is fixedly connected to the push rod 26, and the end of the push rod 26 away from the first slider 9 is used to abut against the second slider 24.

[0074] The end of the push rod 26 away from the first slider 9 extends beyond the crushing roller 5, so that after the push rod 26 abuts against the second slider 24, the crushing roller 5 only contacts the bristles on the cleaning roller 6, avoiding contact between the crushing roller 5 and the roller body of the cleaning roller 6. Furthermore, by providing the second elastic element 25, when excessively large debris adheres to the crushing roller 5, it can avoid excessive rigid contact between the debris and the cleaning roller 6 after contact during rotation due to the stretchable effect of the cleaning roller 6, thus preventing damage to both the cleaning roller 6 and the crushing roller 5.

[0075] In one embodiment of the present invention, the third driving mechanism includes:

[0076] Multiple support plates 27 are fixedly connected to the inner side wall of the housing 1;

[0077] Multiple telescopic sleeves 28 correspond one-to-one with multiple support plates 27. The telescopic sleeves 28 are fixedly connected between the support plates 27 and the bottom surface of the filter screen 7. The telescopic sleeves 28 are provided with a first single-outlet cylinder 29 fixedly connected to the support plate 27, a vibrator 30 fixedly connected to the bottom surface of the filter screen 7, and a third elastic element 31 fixedly connected between the output end of the first single-outlet cylinder 29 and the vibrator 30.

[0078] During crushing, the vibrator 30 causes the filter screen 7 to vibrate, thereby improving the passing efficiency of the aggregate on the filter screen 7. When maintenance is required, oversized waste falls onto the filter screen 7. Due to the tilting setting of the filter screen 7, the waste moves towards the second discharge port 4 by gravity. When the waste needs to be discharged, the first single-outlet cylinder 29 pushes the filter screen 7 upward, so that the filter screen 7 exceeds the second discharge port 4, and the waste is automatically discharged from the second discharge port 4.

[0079] In one embodiment of the present invention, a pair of guide plates 32 are rotatably connected to the top of the box 1, and a feed inlet 2 is formed between the pair of guide plates 32. A second single-outlet cylinder 33 is provided between the guide plates 32 and the inner side wall of the box 1.

[0080] When cleaning the crushing roller 5, the guide plate 32 can be pushed by the second single-outlet cylinder 33 to make the feed opening 2 between the pair of guide plates 32 smaller, so as to avoid too much garbage falling onto the filter screen 7 during cleaning.

[0081] In one embodiment of the present invention, a baffle 34 is provided at the second discharge port 4, and a third single-outlet cylinder 35 is provided between the baffle 34 and the outer wall of the box 1.

[0082] When discharging oversized pieces of waste from the filter screen 7, the baffle 34 is opened by the third single-outlet cylinder 35 to discharge the waste. During crushing, the baffle 34 closes the second discharge port 4 to prevent dust or sized aggregate from overflowing from the second discharge port 4.

[0083] Furthermore, an extendable and retractable component such as a bellows plate is fixedly connected between the first slider 9 and the second slider 24, and between the second slider 24 and the sliding channel 8, to prevent dust or compliant aggregate from overflowing from the sliding channel 8.

[0084] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0085] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
