[0023] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a concrete block recycling mechanism, including a box body 1, two first crushing rollers 3 are symmetrically rotatably connected at a position near the bottom between the front and rear inner surface walls of the box body 1, two second crushing rollers 4 are symmetrically rotatably connected at a position near the top between the front and rear inner surface walls of the box body 1, a discharge mechanism 6 is arranged near the middle of the right surface of the box body 1, and a diversion mechanism 5 is arranged near the middle of the inside of the box body 1, and the diversion mechanism 5 includes a cylinder 501, the cylinder 501 is fixedly mounted on the front surface of the box body 1, and a connecting block is fixedly connected to the telescopic end of the cylinder 501 502, a redirecting plate 503 is fixedly connected to the rear surface of the connecting block 502, the redirecting plate 503 slides through the left surface of the box body 1 and extends to the other side, the redirecting plate 503 and the cylinder 501 are both inclined, the interior of the box body 1 is wide at the top and narrow at the bottom, a fine material opening 12 is opened near the bottom of the left surface of the box body 1, a slope 11 is set at the inner bottom of the box body 1, the inner bottom of the box body 1 is inclined, a coarse material opening 23 is opened near the middle of the right surface of the box body 1, and the first motor 32 and the second motor 43 are fixedly installed on the rear surface of the box body 1. The output ends all slide through the rear surface of the box body 1 and extend to the front side. The output end of the first motor 32 is fixedly connected to the rear end of one of the first crushing rollers 3. The output end of the second motor 43 is fixedly connected to the rear end of one of the second crushing rollers 4. The front surface of the box body 1 is rotatably connected to two first gears 31 near the middle. The front surface of the box body 1 is rotatably connected to four second gears 41 near the top. The two first gears 31 are meshed and connected to each other. The four second gears 41 are meshed and connected to each other. The two first gears 31 are fixedly connected to the front ends of the two first crushing rollers 3 through shafts. The two second gears 41 are fixedly connected to the front ends of the two second crushing rollers 4 through the shaft, the spacing between the two first crushing rollers 3 is smaller than the spacing between the two second crushing rollers 4, the discharging mechanism 6 includes two guide rails 601, the guide rails 601 are symmetrically fixedly connected to the right surface of the box body 1 near the middle, a baffle 602 is slidably arranged between the inner surface walls of the two guide rails 601, the baffle 602 and the coarse material opening 23 are in corresponding positions, an electric push rod 604 is installed at the bottom of the baffle 602, and a mounting block 603 is fixedly connected to the bottom of the electric push rod 604, and the mounting block 603 is fixedly connected to the right surface of the box body 1.

[0024] The effect achieved by the entire embodiment 1 is that when the device is used to recycle discarded concrete blocks, the blocks are first put into the box 1, and then the first motor 32 and the second motor 43 are started to drive one of the first crushing rollers 3 and the second crushing roller 4 to rotate. At this time, the first crushing roller 3 will drive one of the first gears 31 to rotate and cooperate with the other first gear 31 to drive the other first crushing roller 3 to rotate in the opposite direction, and the second crushing roller 4 will drive the other second crushing roller 4 to rotate in the opposite direction through the four second gears 41, and the distance between the two second crushing rollers 4 is greater than the distance between the two first crushing rollers 3. Therefore, when the concrete blocks pass through the two second crushing rollers 4, they will be crushed into larger particles, and then they will be crushed into smaller particles when they pass through the two first crushing rollers 3. When large-particle concrete blocks are needed, the cylinder 501 is started to contract and cooperate with the connecting The connecting block 502 can drive the redirection plate 503 to be obliquely inserted into the interior of the box body 1. At this time, the concrete blocks broken into large particles will fall to the top of the redirection plate 503 and then be discharged from the coarse material opening 23 on the right. The overall structure is reasonable, and the discarded concrete blocks can be broken into large particles for filling foundations, etc., or broken into small particles for recycling, etc., which solves the problem of a high degree of limitation during recycling. When processing large-particle concrete blocks, the electric push rod 604 is started at the same time during the process of starting the cylinder 501 to drive the baffle 602 to move downward and then leak out of the coarse material opening 23, so that the large-particle concrete blocks are discharged. When processing small-particle concrete blocks normally, the electric push rod 604 is started to drive the baffle 602 to move upward and then close the coarse material opening 23, which can effectively prevent the concrete blocks from falling from the coarse material opening 23. It is highly practical, and the guide rail 601 is set to limit the baffle 602.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, the front and rear inner walls of the box body 1 are symmetrically fixedly connected with guide strips 21, which cooperate with the diversion plate 503. Side stoppers 2 are provided near the bottom of the inner walls on both sides of the box body 1, and guide plates 22 are symmetrically fixedly connected with the inner walls on both sides of the box body 1 near the top.

[0026] The effect achieved by the entire embodiment 2 is that the guide strips 21 are provided to guide the redirection plate 503, and when the redirection plate 503 slides between the guide strips 21, the guide strips 21 support it, thereby improving the stability of the redirection plate 503. The design of the side block 2 prevents the concrete block from falling from the side when passing through the first crushing roller 3. One end of the guide plate 22 is bent downward, and is mainly used to discharge the concrete blocks to be processed to the position between the two second crushing rollers 4.

[0027] Working principle: When using the device to recycle discarded concrete blocks, first put them into the box 1, and then start the first motor 32 and the second motor 43 to drive one of the first crushing rollers 3 and the second crushing roller 4 to rotate. At this time, the first crushing roller 3 will drive one of the first gears 31 to rotate and cooperate with the other first gear 31 to drive the other first crushing roller 3 to rotate in the opposite direction, and the second crushing roller 4 will drive the other second crushing roller 4 to rotate in the opposite direction through the four second gears 41. The distance between the two second crushing rollers 4 is greater than the distance between the two first crushing rollers 3. Therefore, when the concrete block passes through the two second crushing rollers 4, it will be crushed into larger particles, and then it will be crushed into smaller particles when it passes through the two first crushing rollers 3. When large-particle concrete blocks are needed, the cylinder 5 is started. 01 contracts and cooperates with the connecting block 502 to drive the diversion plate 503 to be obliquely inserted into the interior of the box body 1. At this time, the concrete blocks broken into large particles will fall to the top of the diversion plate 503 and then be discharged from the coarse material port 23 on the right. The overall structure is reasonable, and the discarded concrete blocks can be broken into large particles for filling foundations, etc., or broken into small particles for recycling, etc., which solves the problem of high degree of limitation during recycling. When processing large-particle concrete blocks, the electric push rod 604 is started at the same time during the process of starting the cylinder 501, driving the baffle 602 to move downward and then leak out of the coarse material port 23, so that the large-particle concrete blocks are discharged. When processing small-particle concrete blocks normally, starting the electric push rod 604 to drive the baffle 602 to move upward and then close the coarse material port 23 can effectively prevent the concrete blocks from falling from the coarse material port 23, and it is highly practical.
