[0015] 2. By setting up a stirring component, the present invention can stir the construction waste at the discharge port, which can effectively prevent a large amount of construction waste from accumulating at the discharge port and causing blockage.

[0016] 3.

[0023] Example 1 Reference Figure 1-6 This is the first embodiment of the present invention, which provides a construction waste recycling and processing device and method, including a crusher body 1, crushing rollers 2, a feeding port 3, a discharging port 4 and a drive mechanism 5. The feeding port 3 is opened on the upper side of the crusher body 1, and the discharging port 4 is opened on the lower surface of the crusher body 1. Two crushing rollers 2 are provided, and the outer surfaces of the two crushing rollers 2 are rotatably connected to the inner wall of the crusher body 1 through bearings. The drive mechanism 5 is fixedly connected to the front end face of the crushing rollers 2, and the rear surface of the drive mechanism 5 is fixedly connected to the front surface of the crusher body 1. A grinding mechanism 6 is provided on the surface of the feeding port 3. The grinding mechanism 6 includes a grinding roller 61, a first connecting rod 62, a first motor 63, a fixed plate 64, and a drive assembly 65. The grinding roller 61 is located on the left side of the feed port 3. The outer surface of the first connecting rod 62 is fixedly connected to the inner wall of the grinding roller 61. The inner wall of the fixed plate 64 is rotatably connected to the outer surface of the first connecting rod 62 through a bearing. The output end of the first motor 63 is fixedly connected to the front end face of the first connecting rod 62. The rear surface of the first motor 63 is fixedly connected to the front surface of the fixed plate 64. The drive assembly 65 is located on the right side of the fixed plate 64. The drive assembly 65 includes a transmission plate 651, a threaded rod 652, a second motor 653, and a fixed sleeve 654. The left surface of the transmission plate 651 is fixedly connected to the right surface of the fixed plate 64. The outer surface of the threaded rod 652 is rotatably connected to the inner wall of the transmission plate 651 via a thread. The outer surface of the threaded rod 652 is rotatably connected to the inner wall of the crusher body 1 via a bearing. The output end of the second motor 653 is fixedly connected to the upper end face of the threaded rod 652. The inner wall of the fixed sleeve 654 is fixedly connected to the outer surface of the second motor 653. The lower end face of the fixed sleeve 654 is fixedly connected to the upper surface of the crusher body 1. The surface of the crusher body 1 is provided with a first sliding groove 7, and the inner wall of the first sliding groove 7 is slidably connected to the outer surface of the transmission plate 651.

[0024] Specifically, through this design, when large pieces of construction waste are stuck in the feed inlet 3, the grinding roller 61 can grind the upper side of the large pieces of construction waste through high-speed rotation, thereby reducing the volume of the construction waste and making it easier for the construction waste to enter the crusher body 1.

[0025] Furthermore, the crushing roller 2 is driven to rotate by the drive mechanism 5. The crushing roller 2 can crush the incoming construction waste. When large pieces of construction waste cannot pass through the feed port 3, the first motor 63 and the second motor 653 are started by the controller. The first motor 63 drives the grinding roller 61 to rotate through the first connecting rod 62. The second motor 653 drives the threaded rod 652 to rotate. The rotation of the threaded rod 652 can drive the transmission plate 651 to move downward along the inner wall of the first slide groove 7 through the thread. The downward movement of the transmission plate 651 can drive the connecting rod 82 through the fixed plate 64. The connecting rod 82 then drives the grinding roller 61 to move downward together.

[0026] Example 2 In the second embodiment of the present invention, a stirring assembly 8 is provided on the rear end face of the crushing roller 2. The stirring assembly 8 includes a pulley 81, a connecting rod 82, a stirring rod 83, and stirring blades 84. Two pulleys 81 are provided, and the outer surfaces of the two pulleys 81 are connected by belt drive. The front surface of the upper pulley 81 is fixedly connected to the rear end face of the crushing roller 2. The rear end face of the connecting rod 82 is fixedly connected to the front surface of the lower pulley 81. The rear end face of the stirring rod 83 is fixedly connected to the front end face of the connecting rod 82. The outer surface of the stirring rod 83 is rotatably connected to the inner wall of the feed port 4 through a bearing. A plurality of stirring blades 84 are provided, and the side of the plurality of stirring blades 84 near the stirring rod 83 is fixedly connected to the outer surface of the stirring rod 83.

[0027] Specifically, this design allows for the mixing of construction waste at the discharge port, effectively preventing the accumulation of large amounts of construction waste at the discharge port and thus avoiding the risk of blockage.

[0028] Furthermore, when the crushing roller 2 rotates, it can drive the rear pulley 81 to rotate, so that the pulley 81 drives the stirring rod 83 to rotate through the connecting rod 82. The stirring rod 83 then stirs the crushed construction waste through the stirring blade 84, and accelerates the discharge speed of the crushed construction waste.

[0029] Example 3 In the third embodiment of the present invention, a stroke component 9 is provided on the front end face of the stirring rod 83. The stroke component 9 includes a rotating disk 91, a stroke ring 92 and a stroke column 93. The rear surface of the rotating disk 91 is fixedly connected to the front end face of the stirring rod 83, the rear end face of the stroke column 93 is fixedly connected to the front surface of the rotating disk 91, the inner wall of the stroke ring 92 is slidably connected to the outer surface of the stroke column 93, and a sliding component 10 is provided on the outer surface of the stroke ring 92. Two sliding components 10 are provided. The two sliding components 10 include a sliding plate 101 and a support member 102. The sliding plate 101 is fixedly connected to the outer surface of the stroke ring 92 at one end. The inner wall of the support member 102 is slidably connected to the outer surface of the sliding plate 101. The rear surface of the support member 102 is fixedly connected to the front surface of the discharge port 4. Impact components 11 are provided on the rear surface of the sliding plate 101. There are two impact components 11, each including an impact plate 111, a stroke groove 112, a stroke rod 113, and a support rod 114. The impact plate 111 is located on the left and right sides of the discharge port 4. The stroke groove 112 is opened on the surface of the impact plate 111. The outer surface of the stroke rod 93 is slidably connected to the inner wall of the stroke groove 112. The front end face of the stroke rod 93 is fixedly connected to the rear surface of the sliding plate 101. The outer surface of the support rod 114 is fixedly connected to the inner wall of the impact plate 111. The outer surface of the support rod 114 is provided with a fixing member 12. There are four fixing members 12. The four fixing members 12 are fixedly connected to the outer surface of the discharge port 4 on the side near the discharge port 4. The inner wall of the fixing member 12 is rotatably connected to the outer surface of the support rod 114 through a bearing.

[0030] Specifically, this design causes the impact plate 111 to repeatedly impact the outer surface of the discharge port 4, preventing the crushed construction waste from adhering to the inner wall of the discharge port 4 and thus avoiding the risk of blockage.

[0031] Furthermore, when the stirring rod 83 rotates, it can drive the rotating disk 91 on the front surface to rotate. The rotating disk 91 then drives the stroke column 93 on the front surface to move in a circular trajectory. The stroke column 93 presses against the inner wall of the stroke ring 92 and slides along the inner wall of the stroke ring 92. The stroke ring 92 is forced to start moving back and forth. When the stroke ring 92 moves, it can move back and forth along the support member 102 via the sliding plate 101. When the sliding plate 101 moves, it can drive the stroke rod 113 on the rear surface to press against the inner wall of the stroke groove 112, so that the stroke rod 113 slides along the inner wall of the stroke groove 112. At this time, the impact plate 111 is forced to swing back and forth around the support rod 114 as the rotation center and impact the outer surface of the crusher body 1.

[0032] Working principle: The crushing roller 2 is driven to rotate by the drive mechanism 5. The crushing roller 2 can crush the incoming construction waste. When large pieces of construction waste cannot pass through the feed port 3, the first motor 63 and the second motor 653 are started by the controller. The first motor 63 drives the grinding roller 61 to rotate through the first connecting rod 62. The second motor 653 drives the threaded rod 652 to rotate. The rotation of the threaded rod 652 can drive the transmission plate 651 to move downward along the inner wall of the first slide groove 7 through the thread. The downward movement of the transmission plate 651 can drive the connecting rod 82 through the fixed plate 64. The connecting rod 82 then drives the grinding roller 61 to move downward together. When the crushing roller 2 rotates, it drives the pulley 81 at the rear end to rotate, which in turn drives the stirring rod 83 to rotate via the connecting rod 82. The stirring rod 83 then stirs the crushed construction waste through the stirring blades 84, accelerating the discharge speed of the crushed construction waste. At the same time, the stirring rod 83 drives the rotating disk 91 on the front surface to rotate, which in turn drives the stroke column 93 on the front surface to move in a circular trajectory. The stroke column 93 presses against the inner wall of the stroke ring 92 and slides along the inner wall of the stroke ring 92, forcing the stroke ring 92 to begin to move back and forth. When the stroke ring 92 moves, it can move back and forth along the support member 102 via the sliding plate 101. When the sliding plate 101 moves, it drives the stroke rod 113 on the rear surface to press against the inner wall of the stroke groove 112, causing the stroke rod 113 to slide along the inner wall of the stroke groove 112. At this time, the impact plate 111 is forced to swing back and forth around the support rod 114 as the rotation center, impacting the outer surface of the crusher body 1.

[0033] In summary, the combination of the grinding mechanism 6, the first chute 7, the mixing component 8, the stroke component 9, the sliding component 10, the impact component 11, and the fixing component 12 solves the problems of large construction waste easily getting stuck at the feeding port, requiring workers to use professional tools to clear it, and the risk of blockage at the feeding port when a large amount of construction waste is broken and flows out.

There are two impact assemblies (11). The two impact assemblies (11) include an impact plate (111), a stroke groove (112), a stroke rod (113), and a support rod (114). The impact plate (111) is located on the left and right sides of the discharge port (4). The stroke groove (112) is opened on the surface of the impact plate (111). The outer surface of the stroke column (93) is slidably connected to the inner wall of the stroke groove (112). The front end face of the stroke column (93) is fixedly connected to the rear surface of the sliding plate (101). The outer surface of the support rod (114) is fixedly connected to the inner wall of the impact plate (111).

8. The construction waste recycling and utilization device as described in claim 7, characterized in that: The outer surface of the support rod (114) is provided with a fixing member (12), and four fixing members (12) are provided. The four fixing members (12) are fixedly connected to the outer surface of the discharge port (4) on the side near the discharge port (4). The inner wall of the fixing member (12) is rotatably connected to the outer surface of the support rod (114) through a bearing.

9. A construction waste recycling and processing device and method as described in claims 1 to 8, and its usage method, the usage method includes the following steps: Step 1: Drive the crushing roller (2) to rotate through the drive mechanism (5). The crushing roller (2) can crush the incoming construction waste. When large pieces of construction waste cannot pass through the feed port (3), start the first motor (63) and the second motor (653) through the controller. The first motor (63) drives the grinding wheel to rotate through the first connecting rod (62). The second motor (653) drives the threaded rod (652) to rotate. The rotation of the threaded rod (652) can drive the transmission plate (651) to move downward along the inner wall of the first slide groove (7) through the thread. The downward movement of the transmission plate (651) can drive the connecting rod (82) through the fixed plate (64). The connecting rod (82) then drives the grinding wheel to move downward together. Step 2: When the crushing roller (2) rotates, the crushing roller (2) can drive the pulley (81) at the rear end to rotate, so that the pulley (81) drives the stirring rod (83) to rotate through the connecting rod (82). The stirring rod (83) then stirs the crushed construction waste through the stirring blade (84) and accelerates the discharge speed of the crushed construction waste. Step 3: When the stirring rod (83) rotates, the stirring rod (83) can drive the rotating disk (91) on the front surface to rotate. The rotating disk (91) then drives the stroke column (93) on the front surface to move in a circular trajectory. The stroke column (93) squeezes the inner wall of the stroke ring (92) and slides along the inner wall of the stroke ring (92). The stroke ring (92) is forced to start moving back and forth. When the stroke ring (92) moves, it can move back and forth along the support (102) through the sliding plate (101). When the sliding plate (101) moves, it can drive the stroke rod (113) on the rear surface to squeeze the inner wall of the stroke groove (112), so that the stroke rod (113) slides along the inner wall of the stroke groove (112). At this time, the impact plate (111) is forced to swing back and forth with the support rod (114) as the rotation center to impact the outer surface of the crusher body (1).
