[0030] A dispersion plate 5, which is arranged above one of the crushing rollers 2 and fixed to the inner wall of the processing box 1, a guide plate 6 fixed to the inner wall of the processing box 1 is arranged above the other crushing roller 2, a feed hopper 7 connected to the top surface of the processing box 1 is arranged above the guide plate 6, and a feed dispersion mechanism 8 matched with the crushing roller 2 is arranged between the guide plate 6 and the dispersion plate 5;

[0031] A screening plate 9 is arranged below the two crushing rollers 2 and rotates through the processing box 1. A discharging plate 10 is arranged below the screening plate 9 and is rotatably connected to the inner wall of the processing box 1. A feeding and rotating mechanism 11 cooperating with the feeding and dispersing mechanism 8 is arranged between the screening plate 9 and the discharging plate 10.

[0032] It should be noted that the feed dispersion mechanism 8 is used to carry out preliminary dispersion treatment on the construction waste sent into the processing box 1, so as to improve the crushing effect of the two crushing rollers 2 on the construction waste, and to a certain extent prevent the local accumulation of construction waste between the two crushing rollers 2. The supply and rotation mechanism 11 is used for the synchronous reciprocating swing of the discharge plate 10 and the screening plate 9, and it moves synchronously with the feed dispersion mechanism 8.

[0033] Further as Figure 1 , Figure 2 and Figure 4As shown, it is worth to explain in detail that the feed dispersing mechanism 8 includes a plurality of dispersing blades 81, and the plurality of dispersing blades 81 are coaxially distributed and rotatably mounted on the inner walls at both ends of the processing box 1, and the adjacent dispersing blades 81 are staggered and fitted;

[0034] Two transmission pulleys 82, one of which is coaxially fixed to the rotating shaft of the plurality of dispersion blades 81, and the other is coaxially fixed to the rotating shaft of the crushing roller 2 located above, and the outer surfaces of the two transmission pulleys 82 are provided with transmission belts 83;

[0035] It should be noted that the drive pulley 82 and the drive belt 83 are used to provide synchronous and unidirectional transmission between the dispersion blade 81 and the upper crushing roller 2. In addition, the drive pulley 82 and the drive belt 83 here can be replaced by a sprocket and a chain.

[0036] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth specifically explaining that the supply and rotation mechanism 11 includes a rotating disk 111, which is coaxially fixed with the rotating shaft of the dispersion blade 81, and a rotating column 112 is fixed to the outer surface of the rotating disk 111, and a guide sleeve 113 fixed to the outer end surface of the processing box 1 is arranged below the rotating column 112, and a movable rod 114 is slidably penetrated through the inner wall of the guide sleeve 113, and a limiting ring 115 fixed to the top of the movable rod 114 is arranged on the periphery of the rotating column 112, and a lifting rack rod 116 is fixed to the bottom end of the movable rod 114;

[0037] Two reversing gears 117, the two reversing gears 117 are symmetrically coaxially fixed to the two ends of the rotating shaft of the screening plate 9, and the lifting rack rod 116 is meshedly connected with the adjacent reversing gears 117;

[0038] Two track blocks 118, the two track blocks 118 are respectively arranged on the outside of the two reversing gears 117 and are respectively fixed to the two outer end surfaces of the processing box 1, the inner wall of each track block 118 is slidably connected with a pressing rack rod 119, the pressing rack rod 119 is meshedly connected with the adjacent reversing gear 117, a pressing rod 1110 is rotatably connected between the bottom ends of the two pressing rack rods 119, and through grooves 1111 for sliding of the pressing rod 1110 are arranged at both ends of the discharge plate 10;

[0039] It should be noted that the through groove 1111 is used to provide a movable space for the pressing rod 1110 when it performs reciprocating pressing along with the pressing rack rod 119 , so that the discharge plate 10 can reciprocate and swing on the inner wall of the processing box 1 along with the movement of the pressing rod 1110 .

[0040] This scheme has the following working process: when recycling and processing the construction waste generated by civil engineering construction, firstly, the construction waste to be processed is tilted into the interior of the processing box 1 through the feed hopper 7, and the flow is guided by the guide plate 6 so that a large amount of construction waste is located above the dispersion plate 5 for temporary storage. At this time, through the drive of the crushing motor 4 and the meshing transmission of the two transmission gears 3, the two crushing rollers 2 move synchronously toward the center in the processing box 1, and through the transmission action of the transmission pulley 82 and the transmission belt 83, the dispersion blade 81 rotates synchronously in the same direction with the upper crushing roller 2, so that the temporarily stored construction waste is dispersed and rotated by the dispersion blade 81, and through the guidance of the guide plate 6, the construction waste is concentrated and enters from the center of the two crushing rollers 2, so that the construction waste is crushed to meet the specifications of renewable resources through the synchronous reverse rotation of the two crushing rollers 2, thereby completing the preliminary crushing treatment of the civil engineering construction waste;

[0041] When the crushed construction waste falls to the top of the screening plate 9, the rotating disk 111 and the rotating column 112 rotate synchronously with the dispersing blade 81, and the guide sleeve 113 limits the upper and lower movable positions of the movable rod 114 and the rotating column 112 is always located in the limiting ring 115 for rotation, so that the movable rod 114 drives the lifting rack rod 116 at the bottom thereof to perform a reciprocating motion from lifting upward to resetting downward, and the meshing transmission of the lifting rack rod 116 and the reversing gear 117 makes the reversing gear 117 and the screening plate 9 on the processing box 1 The reciprocating swing is performed, that is, the crushed construction waste dropped onto the screening plate 9 is subjected to swing screening treatment. During the reciprocating rotation of the reversing gear 117, the meshing transmission of the reversing gear 117 and the pressing rack rod 119 makes the pressing rack rods 119 at both ends synchronously perform a reciprocating motion from pressing downward to resetting upward in the track block 118, so that the through groove 1111 limits the pressing rod 1110, so that the discharging plate 10 is subjected to reciprocating swing in the processing box 1, thereby realizing the swing discharging of the construction waste after crushing and screening.

[0042] According to the above working process, it can be known that: the construction waste to be processed enters the dispersion blade 81 through the feed hopper 7, and is driven by the crushing motor 4 to make the dispersion blade 81, the crushing roller 2, the screening plate 9 and the discharge plate 10 move synchronously, so that the construction waste is rotated and dispersed through the dispersion blade 81 and enters between the two crushing rollers 2 for crushing processing, and the reciprocating swinging screening plate 9 and the reciprocating swinging discharge plate 10 are used to realize the swing screening and swing discharging of the crushed construction waste, which greatly improves the screening and discharging rate of the construction waste. In addition, the construction waste is dispersed and tilted to enter between the two crushing rollers 2 for crushing, thereby effectively avoiding the phenomenon of concentrated impact of the construction waste on the screening plate 9 and the discharge plate 10, effectively improving the service life of the screening plate 9 and the discharge plate 10, and enhancing its practicality.

[0043] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth explaining in detail that the screening plate 9 and the discharge plate 10 are respectively rotated on the inner walls on both sides of the processing box 1, and the top surface of the screening plate 9 and the top surface of the discharge plate 10 are both inclined slopes. The screening plate 9 and the discharge plate 10 are staggered, so that the construction waste screened by the screening plate 9 can be separated and processed from both sides, which improves the convenience of collection after screening and discharging to a certain extent, and the slope setting, combined with the reciprocating swing of the screening plate 9 and the discharge plate 10, effectively improves the screening and discharging effects.

[0044] Further as Figure 4 As shown, it is worth explaining in detail that the top surface of the dispersion plate 5 is arranged in an arc surface, so that the construction waste entering the dispersion plate 5 can be better dispersed by the rotation of the dispersion blade 81 and enter between the two crushing rollers 2 for crushing processing. The top surface of the guide plate 6 is arranged in an inclined slope surface, and the ends of the dispersion plate 5 and the guide plate 6 that are close to each other are located at the center of the two crushing rollers 2, so that the construction waste fed from the feed hopper 7 and the construction waste fed into the dispersion blade 81 are guided between the two crushing rollers 2 for crushing processing.

[0045] Further as Figure 1 and Figure 4 As shown, it is worth explaining in detail that the feed hopper 7 and the top surface of the processing box 1 are inclined, and the inclination direction of the feed hopper 7 is the same as the inclination direction of the two crushing rollers 2. The feed hopper 7 is inclined so that the construction waste to be processed is inclined to enter the processing box 1, which reduces the local impact phenomenon to a certain extent, and its inclination direction is the same as that of the crushing rollers 2, so that the construction waste after entering the dispersion blade 81 for dispersion treatment enters between the two crushing rollers 2 again, which can effectively avoid excessive aggregation between the two crushing rollers 2 and significantly improve the effect of crushing the construction waste.

[0046] In summary: through the driving of the crushing motor 4, the dispersing blade 81, the crushing roller 2, the screening plate 9 and the discharging plate 10 are made to move synchronously, so that the construction waste is rotated and dispersed by the dispersing blade 81 and enters between the two crushing rollers 2 for crushing processing, and the reciprocating oscillating screening plate 9 and the reciprocating oscillating discharging plate 10 realize the swing screening and swing discharging of the crushed construction waste, which greatly improves the screening and discharging rate of the construction waste;

[0047] The screening plates 9 and the discharge plates 10 are staggered, so that the construction waste screened by the screening plates 9 can be separated and processed from both sides, which improves the convenience of collection after screening and discharge to a certain extent. The feed hopper 7 is tilted, so that the construction waste to be processed is tilted into the processing box 1, which reduces the local impact phenomenon to a certain extent, and its tilt direction is the same as that of the crushing roller 2, so that the construction waste after entering the dispersion blade 81 for dispersion processing can enter between the two crushing rollers 2 again, which can effectively avoid excessive aggregation between the two crushing rollers 2 and significantly improve the effect of crushing the construction waste.

[0048] The crushing motor 4 can be purchased from the market and equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
