A leakage plate 107 is fixedly connected to the opening of the collecting hopper 106, and the leakage plate 107 is located below the discharge port of the filter cartridge 81. The bottom end of the No. 1 drop hopper 6 is extended and arranged in the inlet 108. The collection hopper 106 and the leakage plate 107 cooperate to collect the concrete crushed materials discharged from the drop port of the filter cartridge 81, so as to further improve the quality of the concrete waste. The collected gravel and the gravel discharged from the No. 1 drop hopper 6 will all enter the crushing barrel 101, and the No. 3 driving shaft 103 will drive multiple crushing disks 104 to rotate between multiple crushing rings 105, so as to perform secondary crushing on the gravel that has undergone primary crushing, so as to crush the gravel into a particle size that meets the use requirements, and the distance between the crushing disk 104 and the crushing ring 105 can be adjusted by the lifting component 11 to adjust the particle size of the secondary crushing, so as to crush the gravel size suitable for different use requirements, thereby improving the convenience of use.

[0034] like Fig.14 and Fig.15In the figure, the lifting assembly 11 includes a lifting frame 111, which is fixedly connected to the curved surface of the sliding sleeve 102.

[0035] During operation, when the existing crusher is crushing concrete containing steel bars, it is difficult to effectively peel off the concrete attached to the steel bars, and the concrete on the surface of the steel bars needs to be thoroughly peeled off later. In addition, when the steel bars and other debris enter the crusher, they are also easily entangled in the crusher, which can easily cause damage to the crusher. In this solution, by throwing concrete waste from the top of the outer shell 2 and throwing it between the fixed jaw plate 31 and the movable jaw plate 32, under the drive of the crankshaft 33 by the No. 1 motor 36, the lower end of the movable jaw plate 32 will rotate in the fixed shaft sleeve 34 through the connecting plate 35, and the higher end of the movable jaw plate 32 will swing with the connecting axis between the connecting plate 35 and the movable jaw plate 32 as the axis due to the rotation of the crankshaft 33, thereby causing the movable jaw plate 32 to engage and rub with the fixed jaw plate 31, so as to crush the concrete. The soil waste is crushed by the engagement and rubbing of the movable jaw plate 32 and the fixed jaw plate 31. The crushed debris will pass through the gaps between the multiple cross bars 41 and enter the outer shell 2, while the longer steel bars mixed therein will be blocked by the multiple cross bars 41. The No. 1 hydraulic rod 43 is controlled to extend. When the inclined No. 1 hydraulic rod 43 is extended, it will drive the pressing plate 44 to move above the multiple cross bars 41, so that the pressing plate 44 moves above the multiple cross bars 41, and when the pressing plate 44 moves, it drives the cutter 45 to move toward the upper surface of the support beam 42. Under the support of the support beam 42, the cutter 45 will cut the steel bars above the multiple cross bars 41 to shorten their length so that they can pass through the gaps between the multiple cross bars 41, while the shorter steel bars will directly pass through the gaps between the multiple cross bars 41 and enter the outer shell 2. The No. 1 drive shaft 53 is driven by the No. 1 drive shaft 53 to drive the multiple telescopic components 54 thereon to rotate around the No. 1 drive shaft 53, and the multiple telescopic components 54 drive the driven cylinder 55 to rotate synchronously with the No. 1 drive shaft 53. Under the action of the special-shaped guide ring 52, when the telescopic component 54 rotates to above the No. 1 drop hopper 6, under the action of the No. 1 spring 5409, the telescopic plate 5402 will extend out of the hollow plate 5401. At this time, when crushed materials and metal debris fall on the telescopic plate 5402, the metal debris will be adsorbed on its surface under the action of the magnetic plate 5404. With the drive of the No. 1 drive shaft 53, the crushed stones and debris falling thereon will rotate with the telescopic plate 5402, and when the telescopic plate 5402 rotates and the No. 1 drop hopper 6 opens, the crushed stones on the telescopic plate 5402 will fall into the No. 1 drop hopper 6, and the metal debris will be attracted by the magnetic plate 5404. The plate 5404 continues to rotate under the adsorption of the plate 5404, and when the telescopic plate 5402 drives the metal debris to rotate to the opening of the No. 2 drop hopper 7, under the action of the special-shaped guide ring 52, it will push the guide wheel 5406 in the direction of the No. 1 drive shaft 53, and when the guide wheel 5406 is squeezed, it will squeeze the No. 1 spring 5409 to shrink and shrink the telescopic plate 5402 into the hollow plate 5401. In this process, the metal debris adsorbed on the magnetic plate 5404 will be scraped off by the opening of the hollow plate 5401 and fall into the No. 2 drop hopper 7, thereby removing the metal debris such as steel bars in the concrete waste, and with the drive of the No. 1 drive shaft 53, the retracted telescopic plate 5402 will extend out of the hollow plate 5401 again under the action of the No. 1 spring 5409 and the guidance of the special-shaped guide ring 52 to the guide wheel 5406 when it rotates above the No. 1 drive shaft 53, so as to carry out the next separation operation; Under the action of the vibration motor 13, the No. 1 drop hopper 6 and the secondary separation component 8 will vibrate, and the crushed stones entering the No. 1 drop hopper 6 will directly enter the secondary crushing component 10, and the metal debris entering the No. 2 drop hopper 7 will enter the secondary separation component 8, and the No. 3 motor 85 will drive the No. 2 drive shaft 83. When the No. 2 drive shaft 83 rotates, it will drive the multiple groups of hammer assemblies 84 on it to rotate in the filter cartridge 81. Under the action of the centrifugal force of the No. 2 drive shaft 83, the hammer head 8403 will rotate around the No. 2 drive shaft 83 in the filter cartridge 81. When the metal debris enters the filter cartridge 81, When the metal debris is in the filter, the rapidly rotating hammer head 8403 will hammer the concrete remaining on the metal debris so that the remaining concrete will fall off from it, and the fallen gravel will enter the outer cylinder 82 through the filter cylinder 81, and enter the No. 1 drop hopper 6 from the connecting pipe 9 at the lower end of the outer cylinder 82 for collection, and the steel bars after the hammering will be discharged from the discharge port of the filter cylinder 81, so that the steel bars in the waste can be recycled, and the gravel discharged from the filter cylinder 81 after discharging will fall on the leakage plate 107, and enter the secondary crushing assembly 10 through the collecting hopper 106 for collection, thereby improving the utilization rate of concrete waste; When the crushed stone enters the secondary crushing assembly 10, the third drive shaft 103 is driven by the fourth motor 1012, and the third drive shaft 103 rotates in the sliding sleeve 102, and the plurality of crushing disks 104 rotate between the plurality of crushing rings 105. As the gaps between the plurality of crushing disks 104 and the plurality of crushing rings 105 gradually decrease from top to bottom, the crushed stone entering the crushing barrel 101 is crushed again in the process of falling downward, so that the concrete waste is crushed into the required particle size for recycling; By controlling the No. 2 hydraulic rod 112 to rise and fall, the No. 2 hydraulic rod 112 will drive the lifting frame 111 to rise and fall when it is extended and retracted, and the lifting frame 111 is fixed to the sliding sleeve 102. When the sliding sleeve 102 rises and falls, it will drive the No. 3 driving shaft 103 to rise and fall, and when the No. 3 driving shaft 103 rises and falls, it will drive the multiple crushing discs 104 thereon to move, thereby adjusting the gap size between the crushing disc 104 and the crushing ring 105, so as to adjust the size of the crushed stones crushed by the secondary crushing assembly 10, thereby improving the scope of application after the crushed stones are crushed and improving the convenience of use; The combination achieves the purpose of removing steel bars and metal debris when crushing concrete waste, effectively avoiding steel bars and other metal debris from being drawn into the device and causing damage to the device, and can peel off the auxiliary concrete on the steel bars, effectively improving the utilization efficiency of concrete waste.
