[0002] Reinforced concrete is an important component of modern buildings. Reinforced concrete generally has a lifespan of only a few decades and will become waste concrete after use. Waste concrete can be used as recycled concrete aggregate and as raw material for making new concrete.

[0003] In the process of making recycled aggregate from reinforced concrete, grinding and crushing of recycled aggregate is an indispensable process. The purpose of grinding recycled aggregate is to obtain aggregate particles of appropriate particle size. In order to obtain recycled aggregate particles of different particle sizes, coarse grinding and fine grinding are required. Particles of different particle sizes are ground and crushed on the corresponding equipment.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 3 The present invention provides a device for controlling the particle size of recycled aggregate from construction waste. The technical solution is as follows:

[0022] A device for controlling the particle size of recycled aggregate from construction waste comprises a base 1, an outer cylinder 2, a support plate 3, a top cover 4, and a crushing mechanism. The outer cylinder 2 is fixedly mounted on the top wall of the base 1, the crushing mechanism is arranged inside the outer cylinder 2, the top cover 4 is fixedly mounted on the top wall of the outer cylinder 2 through the support plate 3, and a particle size adjustment device is also provided at the bottom of the outer cylinder 2.

[0023] There are two support plates 3, which support the top cover 4. The space between the two support plates 3 becomes the feed port 15. The bottom of the outer cylinder 2 is provided with a discharge port 7. Reinforced concrete or stones are manually put into the feed port 15. After being crushed and ground by the crushing mechanism, the recycled aggregate is formed and flows out from the discharge port 7 at the bottom. When the required recycled aggregate particle size changes, the particle size adjustment device can be used to change the crushing fineness of the stone by the crushing mechanism, thereby changing the particle size of the recycled aggregate.

[0024] The crushing mechanism includes a motor 5, a guide plate 11, a transmission rod 14, a grinding disc 17, and a rotating drum 18. The motor 5 is fixedly mounted on the top wall of the top cover 4, and the output end of the motor 5 extends to the bottom of the top cover 4. The guide plate 11 is fixedly mounted on the inner wall of the outer drum 2. The transmission rod 14 is fixedly connected to the output end of the motor 5 through a coupling 16. The grinding disc 17 is movably mounted on the outer wall of the bottom of the transmission rod 14 and can swing around the transmission rod 14.

[0025] The rotating drum 18 is provided at the bottom of the transmission rod 14 and is located inside the bottom of the grinding disc 17 . The rotating drum 18 is cam-shaped with inconsistent radii on both sides. The side wall of the rotating drum 18 rests against the inner wall of the grinding disc 17 .

[0026] After stones are manually introduced through the feed port 15, they move downward through the guide plate 11 into the gap between the grinding disc 17 and the guide plate 11. Driven by the rotation of the drum 18, the grinding disc 17 intermittently squeezes the stones, crushing them. The distance between the grinding disc 17 and the bottom inner wall of the guide plate 11 determines the size of the recycled aggregate particles. The size adjustment device adjusts the distance between the grinding disc 17 and the guide plate 11 to adjust the size of the recycled aggregate particles.

[0027] The adjusting device includes a threaded column 12, a threaded sleeve 13, and a toggle rod 10. A cross bar is provided inside the outer cylinder 2, the threaded column 12 is fixedly mounted on the cross bar, the threaded sleeve 13 is threadedly mounted on the threaded column 12, the toggle rod 10 is fixedly connected to the threaded sleeve 13, an arc-shaped groove 9 is provided on the side wall of the outer cylinder 2, the toggle rod 10 extends outward through the arc-shaped groove 9, the top of the threaded sleeve 13 abuts against the bottom wall of the rotating cylinder 18, and the arc-shaped groove 9 is provided with multiple grooves.

[0028] When the particle size of the recycled aggregate particles needs to be adjusted, the toggle rod 10 is manually held and rotated, causing the threaded sleeve 13 and the threaded column 12 to rotate relative to each other, and the threaded sleeve 13 moves upward. The threaded sleeve 13 pushes the rotating drum 18 to move upward, and the rotating drum 18 pushes the grinding disc 17 upward to move, so that the distance between the grinding disc 17 and the bottom inner wall of the guide plate 11 is adjusted, thereby changing the particle size of the recycled aggregate particles.

[0029] The toggle lever 10 has a certain directional elasticity. The toggle lever 10 can be pressed down manually to make it leave the groove and then rotated. Each groove corresponds to a rotation distance, and the toggle lever 10 can be rotated to the corresponding groove according to needs.

[0030] A plurality of tooth grooves are provided in the middle of the rotating drum 18 and arranged in a circular array. A gear cylinder 19 is fixedly mounted on the bottom of the transmission rod 14 and a plurality of key teeth are provided on the gear cylinder 19 at intervals to cooperate with the tooth grooves.

[0031] A gear cylinder 19 is provided to cooperate with the key teeth on the plurality of tooth grooves, and the gear cylinder 19 is used to drive the rotating drum 18 to rotate. The gear cylinder 19 and the rotating drum 18 can also generate relative sliding in the vertical direction, so that the rotating drum 18 will not interfere with the transmission rod 14 when pushing the grinding disc 17 upward.

[0032] The bottom of the base 1 is further provided with a supporting foot 8 , and the supporting foot 8 is provided with a shock-absorbing spring 6 .

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
