[0003] The patent application with the application number CN202011172880.2 discloses a building energy-saving and environmental protection device, which consists of a bending and compressing mechanism, an installation frame, a supporting arm, and a waste storage box. The bending and compressing mechanism is arranged in the installation frame, the waste storage box is arranged in the installation frame, the waste storage box is directly below the bending and compressing mechanism, and openings are provided on both sides of the installation frame. There are two supporting arms. However, this patent also has the following deficiencies.

The components inside the equipment are prone to damage under such unstable working conditions, increasing the maintenance cost and downtime, and further reducing the processing efficiency.

[0040] The crushing protection mechanism 3, the crushing protection mechanism 3 includes a first rotating shaft 301, the first rotating shaft 301 is fixedly connected to the outer surface of the eccentric shaft 5, a first connecting rod 302 is rotatably connected to the outer surface of the first rotating shaft 301, an arc-shaped connecting block 303 is fixedly connected to the outer surface of the first connecting rod 302, a screw 304 is rotatably connected to the inside of the arc-shaped connecting block 303 through a through hole, a triangular rotating shaft 305 is rotatably connected to the inside of the first connecting rod 302 through a through hole, a second rotating shaft 306 is rotatably connected to the inside of the triangular rotating shaft 305, and an electromagnet 307 is fixedly connected to the inside of the second rotating shaft 306.

[0041] The crushing protection mechanism 3 further includes a triangular column 308, the second rotating shaft 306 is slidably connected to the triangular column 308 through a card slot, a card slot column 309 is slidably connected to the outer surface of the triangular rotating shaft 305, a card slot connecting block 310 is clamped to the top of the triangular rotating shaft 305, a second moving jaw plate 311 is clamped to the outer surface of the card slot connecting block 310, and a flat plate 312 is fixedly connected to the outer surface of the card slot column 309.

[0042] The first rotating shaft 301 is eccentrically and fixedly connected to the outer surface of the eccentric shaft 5, the screw 304 is threadedly connected to the second rotating shaft 306, the outer surface of the electromagnet 307 is in contact with the outer surface of the triangular column 308, the card slot column 309 is rotatably connected to the outer surface of the eccentric shaft 5. By providing the crushing protection mechanism 3, the preliminary crushing treatment of construction waste is realized through the second moving jaw plate 311 and the flat plate 312, which can avoid the blockage of large-volume waste at the feed inlet, thereby ensuring the smooth progress of the crushing process; and the loose part on the surface of the waste can be removed through the second moving jaw plate 311; the electromagnet 307 and the triangular column 308 are adapted to different sizes of waste, effectively preventing the loosening and jumping problems caused by the clamping of the crusher, and greatly ensuring the stability of the entire crushing process and the safe operation of the crusher.

[0043] The working principle of this embodiment is as follows: When using this building energy-saving and environmental protection device, the waste is put in through the flat plate 312. At this time, while the eccentric shaft 5 rotates, the first connecting rod 302 is driven to rotate by the first rotating shaft 301 arranged eccentrically, and drives the triangular rotating shaft 305 to slide inside the slot of the slot column 309. The sliding of the triangular rotating shaft 305 drives the slot connecting block 310 to slide. At this time, the slot connecting block 310 drives the second moving jaw plate 311 to slide along the slot of the slot column 309, and the slot column 309 swings around the eccentric shaft 5 following the rotation of the triangular rotating shaft 305, so that the second moving jaw plate 311 slides upward and moves upward and to the right at the same time, realizing the preliminary extrusion and crushing of the waste. When it is necessary to adjust the second moving jaw plate 311 to adapt to wastes of different sizes, the screw 304 rotates, drives the second rotating shaft 306 to rotate and move along the axis direction of the screw 304, drives the triangular rotating shaft 305 to move, so that it moves out of the slot connecting block 310. At the same time, after moving out, the electromagnet 307 is activated to push the triangular column 308 to be clamped with the slot of the triangular rotating shaft 305, so that the triangular rotating shaft 305 rotates. After rotating a certain angle, the electromagnet 307 sucks back the triangular column 308, so that the triangular rotating shaft 305 stops rotating, and the screw 304 rotates in the reverse direction, so that the triangular rotating shaft 305 rotated by a certain angle is re-clamped with the slot connecting block 310, realizing the angle adjustment of the slot connecting block 310, and thus realizing the angle adjustment of the second moving jaw plate 311.

[0044] Embodiment 2: Please refer to Figures 4 - 6 , on the basis of Embodiment 1, the present invention provides a technical solution: The horizontal limiting mechanism 6 includes a first sliding rod 601, the first sliding rod 601 is fixedly connected to the top of the crusher frame 2, the outer surface of the first sliding rod 601 is slidably connected with a first slot slider 602, the outer surface of the first slot slider 602 is fixedly connected with a semi-circular ring 603, the inside of the first slot slider 602 is clamped with a first arc-shaped block 604, the outer surface of the semi-circular ring 603 is fixedly connected with a sector-shaped ring 605 through a circular column, the outer surface of the semi-circular ring 603 is slidably connected with a first rotating block 606 and a second rotating block 607, the outer surface of the first rotating block 606 is fixedly connected with a second sliding rod 608, the outer surface of the second sliding rod 608 is fixedly connected with a first spring 609, the top of the first spring 609 is fixedly connected with the lower surface of the second rotating block 607, the lower surface of the first rotating block 606 is fixedly connected with a flexible connecting block 610, the lower surface of the flexible connecting block 610 is fixedly connected with the upper surface of the second rotating block 607, the inside of the first rotating block 606 is fixedly connected with an elastic strut 611 through a slot, and the top of the elastic strut 611 is fixedly connected with the slot of the second rotating block 607.

[0045] The outer surface of the first arc-shaped clamping block 604 is in contact with the outer surfaces of the first rotating block 606 and the second rotating block 607. The first rotating block 606 is clamped with the second rotating block 607. The outer surface of the second rotating block 607 is in contact with the outer surface of the sector-shaped ring 605. The outer surface of the first arc-shaped clamping block 604 is in contact with the outer surface of the sector-shaped ring 605. By providing the horizontal limiting mechanism 6, the horizontal limiting of the waste is achieved through the first rotating block 606 and the second rotating block 607, enabling it to fall into the crushing opening more accurately. The elastic strut 611 and the flexible connecting block 610 ensure the stability of the waste in the horizontal direction, reducing the possibility of the waste jumping due to clamping, making the entire crushing process smoother and more orderly, reducing the incidence of equipment failures, extending the service life of the equipment, and providing a strong guarantee for the smooth progress of the waste treatment work.

[0046] The working principle of this embodiment is as follows: When using this building energy-saving and environmental protection device, when waste enters the feed inlet, the waste pushes the first rotating block 606 and the second rotating block 607 to rotate along the outer surface of the semi-circular ring 603, and the elastic strut 611 pulls the first rotating block 606 and the second rotating block 607 inward to limit the waste horizontally on the surface, making the waste more concentrated in the center of the feed inlet during the process of falling into the feed inlet. When the waste is larger, the first rotating block 606 and the second rotating block 607 rotate around the semi-circular ring 603, and the second rotating block 607 rotates out of the range of the sector-shaped ring 605. At this time, the first spring 609 pushes the second rotating block 607 to rotate outward, and the flexible connecting block 610 unfolds and cooperates with the first rotating block 606 to limit the surface of the larger waste. After the waste falls into the feed inlet, the whole mechanism slides on the outer surface of the first sliding rod 601, making the lower surface of the second rotating block 607 contact the upper surface of the waste. At this time, if the waste jumps, the rotation of the second rotating block 607 is limited by the first arc-shaped clamping block 604, preliminarily eliminating the jump.

[0047] Embodiment Three: Please refer to Figures 7 - 8, on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: The limit clamping mechanism 9 includes a lead screw 901, which is fixedly connected to the top of the crusher frame 2. A second groove slider 902 is slidably connected to the outer surface of the lead screw 901. A rotating shaft connecting column 903 is rotatably connected inside the second groove slider 902. A bracket 904 is slidably connected inside the rotating shaft connecting column 903 through a through hole opened therein. A corrugated plate 906 is fixedly connected to the lower surface of the bracket 904. A disc spring 905 is fixedly connected to the upper surface of the corrugated plate 906. The upper surface of the disc spring 905 is fixedly connected to the lower surface of the rotating shaft connecting column 903. A motor 907 is fixedly connected to the outer surface of the bracket 904. An output end of the motor 907 is fixedly connected to a cam 908. A first rotating shaft connecting block 909 is fixedly connected to the outer surface of the rotating shaft connecting column 903. A first rotating rod 910 is rotatably connected to the outer surface of the first rotating shaft connecting block 909. A second rotating shaft connecting block 911 is rotatably connected inside the first rotating rod 910.

[0048] The outer surface of the second rotating shaft connecting block 911 is fixedly connected to the outer surface of the groove connecting block 310. The length of the rotating shaft connecting column 903 is the same as the length of the first moving jaw plate 8. By setting the limit clamping mechanism 9, the corrugated plate 906 is used to effectively clamp the waste in the vertical direction. The disc spring 905 can quickly absorb and resolve the vibration energy generated by the jumping, minimizing the jumping that may interfere with the processing flow. The motor 907 and the cam 908 also provide strong assistance to the crushing process, enabling the jaw plate to act on the waste more accurately and efficiently, and avoiding problems such as uneven and incomplete crushing caused by the shaking of the waste.

[0049] By setting the above mechanisms, the following functions are mainly achieved. The second moving jaw plate 311 and the flat plate 312 are used to improve the processing efficiency and ensure that the waste accurately falls into the crushing port. The horizontal limit mechanism 6 is used to protect the processing equipment, reduce the impact force and friction generated by the jumping of the waste, and reduce equipment wear. The motor 907, the cam 908 and the disc spring 905 are used to extend the service life of the equipment, reduce unstable factors such as the disorderly movement and jumping of the waste, make the whole processing process smoother and more reliable, and enhance the continuity of the construction waste treatment.

[0050] The working principle of this embodiment is as follows: When using this building energy-saving and environmental protection device and when it is necessary to process the bouncing, the card slot connecting block 310 pushes the first rotating rod 910 through the second rotating shaft connecting block 911. The first rotating rod 910 pushes the first rotating shaft connecting block 909. The first rotating shaft connecting block 909 pushes the whole mechanism to rotate around the rotating shaft of the rotating shaft connecting column 903, causing it to deflect by a certain angle and rotate periodically. At this time, the lead screw 901 starts to push the second card slot slider 902 to move downward, and drives the corrugated plate 906 to contact and clamp the surface of the waste through the bracket 904, restricting the bouncing of the waste, and absorbing it through the disc spring 905. At this time, the motor 907 starts, driving the cam 908 to rotate, causing the bracket 904 to vibrate, and driving the corrugated plate 906 to vibrate, so as to counteract and eliminate the bouncing on the surface of the waste, and realizing the intermittent pushing of the corrugated plate 906 and the periodic extrusion of the corrugated plate 906 through the rotation of the cam 908, making the contact between the waste and the first moving jaw plate 8 closer, and realizing the treatment of the waste.
