In the process of conveying the first aggregate into the shaping mechanism 6, the smaller first aggregate can pass through the space between the recovery port 31 and the splashing port 42, at this time, steel balls left in the screening cylinder 2 and the larger second aggregate can enter the inside of the rotating wheel 4 to accelerate through the rotating mechanism 41, so that the second aggregate and the steel balls can be thrown out from the splashing port 42 under the action of centrifugal force and inertia, the second aggregate and the steel balls collide with the first aggregate, and cement paste sand hardened on the surfaces of the first aggregate and the second aggregate is removed through collision. The process only impacts the material with smaller volume by the material with larger volume, the impact effect of the material is increased, and the cement paste sand removal effect of the surface hardening of the recycled aggregate is enhanced.
Because the first aggregate and the second aggregate are waste materials such as building cement and the like, the recycled aggregates are objects with similar density, the recycled aggregates have larger weight as the recycled aggregates have larger volume, and the centripetal force, the inertia and the kinetic energy loss are proportional to the weight, so that the steel balls and the second aggregate lose part of the kinetic energy after colliding with the first aggregate, but because the weight of the steel balls and the second aggregate is larger than that of the first aggregate, the steel balls and the second aggregate can still be continuously transmitted under the action of the centripetal force and the inertia, the steel balls and the second aggregate can pass through the recovery port 31 to be transferred onto the reflux mechanism 7 in the transmission process, and the reflux mechanism 7 can transmit the steel balls and the second aggregate back into the screening cylinder 2 after starting to carry out the reflux process.
It should be noted that, the recycled aggregate entering the particle shaping device 1 always needs to have a requirement on volume, and the recycled aggregate such as the second aggregate placed in the particle shaping device 1 can have a slight requirement on volume, so as to facilitate strengthening the impact effect, and meanwhile, when the second aggregate and the steel ball are in the rotating mechanism 41, the steel ball and the second aggregate are impacted by the centrifugal force, so that the second aggregate is subjected to the grinding and crushing process, the volume and the weight of the second aggregate are reduced, and the second aggregate becomes the first aggregate with the composite requirement after being subjected to multiple grinding.

As shown in fig. 2, 3, 5, 6, 7, 8, 10 and 11, when the first threaded rod 122 is not rotated by the driving assembly 8, the first aggregate is conveyed into the shaping mechanism 6 along the first conveying channel 321, at this time, the second blocking block 641 is blocking the second opening 121, so that the first aggregate is stacked in the discharge hole 12, at this time, the second motor 61 drives the second rotating shaft 63 and the second stirring plate 631 to stir the first aggregate, so that friction is performed between the first aggregates, cement paste sand hardened on the surface of the first aggregate is reduced, and the surface of the first aggregate becomes smooth. When the first aggregate is accumulated for a certain time, the driving assembly 8 drives the first threaded rod 122 to rotate, so that the first annular plate 62 and the second annular plate 64 synchronously move, the housing 621 is firstly used for blocking the first opening 322, then the second blocking block 641 is separated from the second opening 121, the first aggregate is transmitted from the discharge hole 12, and the phenomenon that the first opening 322 is not blocked and the second opening 121 is opened in the transmission process is prevented, so that the first aggregate which is not subjected to secondary polishing is transmitted from the discharge hole 12. The bottom end of the second blocking block 641 is provided with a downward extending blocking ring plate to prevent the second opening 121 from being opened prematurely.
A third spur gear 1221 is sleeved on the first threaded rod 122; the drive assembly 8 comprises a third motor 81, a fourth spur gear 82, a fifth spur gear 83, a first drive socket plate 84 and a second drive socket plate 85; the third motor 81 is fixedly arranged on the outer surface of the discharge hole 12, the fourth spur gear 82 and the fifth spur gear 83 are both sleeved on an output shaft of the third motor 81, the diameter of the fourth spur gear 82 is smaller than that of the fifth spur gear 83, the first transmission sleeve plate 84 is sleeved outside the discharge hole 12, the first transmission sleeve plate 84 is provided with a second tooth surface 841, the second tooth surface 841 is respectively meshed with the third spur gear 1221 and the fourth spur gear 82, the second transmission sleeve plate 85 is provided with a third tooth surface 851 meshed with the fifth spur gear 83, and the other end of the second transmission sleeve plate 85 is connected with the reflux mechanism 7.
As shown in fig. 2, 3, 5, 6, 7, 8, 10 and 11; the third motor 81 drives the fourth spur gear 82 and the fifth spur gear 83 to rotate, so that the first driving sleeve plate 84 drives the third spur gear 1221 and the first threaded rod 122 to rotate through the second tooth surface 841, and the plurality of first threaded rods 122 synchronously rotate, so that the first ring plate 62 and the second ring plate 64 connected with the first threaded rods 122 move, and meanwhile, the second driving sleeve plate 85 is synchronously driven by the fifth spur gear 83 through the third tooth surface 851, so that the reflux mechanism 7 and the shaping mechanism 6 synchronously move up and down. Since the height of the return mechanism 7 required to rise is larger than that of the shaping mechanism 6, it is necessary to reduce the transmission efficiency of the fourth spur gear 82 by reducing the diameter of the fourth spur gear 82, and it is prevented that the same distance as that of the return mechanism 7 rising during the lifting of the shaping mechanism 6 occurs, resulting in damage to the shaping mechanism 6 or the driving unit 8. It should be noted that the fourth spur gear 82 may be a non-complete gear or may be eccentrically connected to the motor, thereby reducing the transmission effect.

As shown in fig. 2, 3, 5, 6, 7, 8, 10 and 11; when the recycling bin 71 is used for receiving the steel balls and the second aggregate, the annular electromagnet 72 can attract the elastic piece 712 and push the elastic piece 712 to enable the elastic piece 712 to be in a contracted state, after the second transmission sleeve plate 85 rotates, the sixth straight gear 74 can drive the second threaded rod 73 to rotate to enable the recycling bin 71 to move upwards, in the moving process, the outer surface of the recycling bin 71 can gradually seal the recycling opening 31 to prevent the steel balls and the second aggregate from being continuously transmitted, meanwhile, the attraction force of the annular electromagnet 72 to the push plate 711 and the elastic piece 712 can be gradually reduced due to the increase of the distance, the elastic force of the elastic piece 712 gradually overcomes the gravity of the steel balls and the second aggregate to move upwards, the steel balls and the second aggregate are pushed to the upper side of the sieving bin 2, and the steel balls and the second aggregate slide into the sieving bin 2 along the top end of the push plate 711. It should be noted that the elastic member 712 is a spring set formed by a plurality of springs for increasing the elastic force, and has a height difference between a plurality of connection ends of the recovery cylinder 71 connected to the second threaded rod 73, so as to enhance the stability and the supporting effect of the recovery cylinder 71.
