Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0057] Embodiment, please refer to Figures 1 to 5, The recycled concrete strengthening device includes a preparation tank 1, and further includes: a stirring component, a defoaming component, a feeding component, and a driving component. A discharge pipe 2 is provided at the bottom of the preparation tank 1, and a valve 3 is installed on the discharge pipe 2.

Through the preparation tank 1, the mixture of the crushed and screened concrete, cement, and water can be placed. Through the stirring component, it can be stirred. While stirring, the defoaming component can eliminate the bubbles inside the mixture, reduce the generation of bubbles, and improve the mixing effect between the crushed and screened concrete, cement, and water. Through the driving component, feeding, defoaming, and material stirring can be driven simultaneously, enabling the above processes to be carried out simultaneously, improving the preparation and strengthening effect of recycled concrete, and thus improving the use quality of recycled concrete.

[0058] In this embodiment, correspondingly, the driving component includes: a motor 4, a driving shaft 5, and a driving wheel 6. The motor 4 is installed on the top of the preparation tank 1 through a bracket. The driving shaft 5 is installed at the bottom output end of the motor 4. The driving wheel 6 is fixedly sleeved outside the driving shaft 5. By rotating the motor 4, the driving shaft 5 and the driving wheel 6 are driven to rotate, providing a power source.

[0059] In this embodiment, correspondingly, the defoaming component includes: a plug rod 7, a sliding frame 8, and a reciprocating lifting mechanism. The plug rod 7 is arranged circumferentially inside the preparation tank 1. The sliding frame 8 is fixedly installed on the inner wall of the preparation tank 1. The plug rod 7 slides through the inside of the sliding frame 8. The reciprocating lifting mechanism is arranged between the driving shaft 5 and the plug rod 7. By driving the reciprocating lifting mechanism through the driving shaft 5, the plug rod 7 continuously moves up and down reciprocally on the sliding frame 8, realizing that the plug rod 7 continuously penetrates into the mixture, thereby continuously piercing the bubbles generated inside it, and improving the mixing effect between the mixtures. The bottom end of the plug rod 7 is provided with a pointed shape.

[0060] In this embodiment, correspondingly, the reciprocating lifting mechanism includes: a cam 9, a runner 10, an elastic member, and a cam 9 rotating mechanism.

The spring 14 is sleeved outside the insertion rod 7, and both ends of the spring 14 are respectively connected to the carriage 8 and the limiting ring 13. Through the cooperation of the limiting ring 13 and the spring 14, under the action of the cam 9, the top end of the insertion rod 7, that is, the runner 10, can always be in contact with the cam 9, so as to cooperate with the cam 9 to realize the continuous reciprocating movement of the insertion rod 7 up and down.

[0063] In this embodiment, correspondingly, the cam 9 rotating mechanism includes a turntable 15, a tooth block 16 and a gear 17. The turntable 15 is fixedly sleeved above the stirring shaft 11.

The motor 4 drives the driving shaft 5 to rotate, the driving shaft 5 drives the stirring shaft 11 to rotate, and the stirring shaft 11 drives the turntable 15 to rotate. Thus, under the meshing of the plurality of tooth blocks 16 and the gear 17, the gear 17 is driven to rotate. The gear 17 rotates concentrically with the cam 9, so as to drive the cam 9 to rotate while stirring, that is, drive the insertion rod 7 to move up and down continuously, and realize the integrated operation of stirring and defoaming at the same time.

[0064] In this embodiment, correspondingly, the feeding assembly includes a hopper 18, a feeding pipe 19, a conveying shaft 20, a driven wheel 21 and a transmission belt 22.

The bracket is fixedly installed inside the hopper 18. The preparation tank 1 stably supports the hopper 18, and the hopper 18 stably supports the bracket.

[0065] In this embodiment, correspondingly, a baffle plate 23 is further included. The baffle plate 23 is in an arch shape and is arranged above the transmission belt 22 and connected to the bracket, reducing the impact of the crushed and screened concrete, cement, and water on the transmission belt 22, the driving wheel 6, and the driven wheel 21.

[0066] In summary, when the regenerated concrete strengthening device is in use, first place the crushed and screened concrete, cement, and water in the hopper 18 in proportion, and then start the motor 4. The motor 4 drives the drive shaft 5, the stirring shaft 11, and the driving wheel 6 to rotate, thereby driving the turntable 15, the stirring blades 12, and the conveying shaft 20 to rotate, continuously conveying the crushed and screened concrete, cement, and water into the preparation tank 1. The rotating turntable 15 drives the cam 9 to rotate, causing the insertion rod 7 to continuously penetrate above the mixture of the crushed and screened concrete, cement, and water to pierce the bubbles generated inside, and at the same time, the mixture is fully stirred again under the action of the stirring blades 12. Finally, open the valve 3 at the bottom of the preparation tank 1 and discharge it to the use position through the discharge pipe 2.
