[0001] The utility model relates to the technical field of concrete recycling, in particular to a waste recycling and reuse device with a screening function. Background Art
[0002] In the prior art, concrete recycling equipment usually uses a crusher to directly use the waste concrete blocks after crushing them, and cannot screen according to the size of the concrete fragments. In addition, the recycling equipment with a screen mechanism also needs to install additional vibration equipment and conveyor belt equipment, which is not conducive to cost saving. Therefore, this application provides a waste recycling and reuse device with a screening function to solve the problems raised in the above background art. Summary of the Utility Model
[0003] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a waste recycling and reuse device with a screening function is proposed. When the device is in use, the impact force of the falling crushed concrete blocks drives the first filter frame to vibrate, and the concrete fragments are screened for the first time. The screened concrete blocks will fall into the second filter frame. When the transmission shaft rotates, the belt drives the runner to rotate. There are two protrusions on the runner, which drive the second filter frame to vibrate up and down during rotation for secondary screening. The screened concrete blocks will slide into the storage box for reuse.

The first filter frame and the second filter frame are respectively rotatably arranged on the uppermost layer and the middle layer of the bracket. A support plate is fixedly arranged on the upper side of the rear end of the first filter frame, and two springs are fixedly arranged on the upper end of the support plate. Convex blocks are fixedly arranged on the upper ends of both sides of the rear end of the second filter frame. A storage frame is slidably arranged inside the lowermost layer of the bracket, and a handle is fixedly arranged on the rear end of the storage frame. The two springs are fixedly connected to the lower end of the housing;
[0006] Through the above technical solution, when the device is in use, the concrete blocks are crushed by the crushing mechanism. The crushed concrete blocks will fall inside the first filter frame. Since the rear end of the first filter frame is connected to the lower end of the housing by a spring, the impact force generated when the concrete blocks fall can drive the first filter frame to vibrate, filtering the concrete blocks. In addition, when the motor drives the transmission shaft to rotate, the transmission shaft drives the rotating shaft to rotate through the belt. When the rotating shaft rotates, the protrusions on both sides will drive the second fixed frame to vibrate up and down for secondary filtration, realizing the recycling of concrete and reducing resource consumption.
[0007] Further, the housing is fixedly arranged at the top of the bracket. Two crushing rollers are rotatably arranged inside the housing. Two gears are respectively fixedly arranged on one side of the two crushing rollers. The transmission shaft is fixedly arranged inside one of the two crushing rollers.

The two groups of first water pipes are fixedly arranged on both sides inside the bracket through a plurality of second fixing blocks. Inside both of the two third fixing blocks, second water pipes are fixedly arranged. The two groups of first water pipes are respectively connected to the front ends of the two second water pipes. A T-shaped water pipe is connected between the two second water pipes, and the T-shaped water pipe is connected to the output end of the water pump.
[0014] Through the above technical solution: it is beneficial to spray water on the first filter frame and the second filter frame from two directions simultaneously, reducing the dust generated by the falling of the concrete blocks and avoiding environmental pollution.
[0015] Further, both the first filter frame and the second filter frame have a certain inclination angle. The front end of the first filter frame is slightly longer than that of the second filter frame, and no filter holes are provided in the extended part of the first filter frame.

The front end of the first filter frame 301 is slightly longer than that of the second filter frame 306, avoiding the mixing of concrete fragments of two different sizes. The extended part of the first filter frame 301 is not provided with filter holes. There are two storage boxes 4, and the heights of the two storage boxes 4 are not equal, which is beneficial to separately loading the cement fragments of the first filter frame 301 and the second filter frame 306.
[0036] Working principle: When the device is in use, the motor 108 drives the transmission shaft 107 to rotate, and the transmission shaft 107 drives the gear 106 and the crushing roller to rotate, so that the concrete blocks can be crushed. After the crushing is completed, the cement blocks will first fall into the inside of the first filter frame 301. Since the rear end of the first filter frame 301 is fixedly arranged at the lower end of the outer shell 101 through the spring 304, the impact force generated when the cement blocks fall can be used to make the first filter frame 301 shake to filter the cement blocks. After filtering, the cement blocks will fall into the inside of the second filter frame 306. The rear end of the second filter frame 306 is arranged on the upper ends of the two rotating wheels 105 through the convex blocks 305 on both sides. A belt 103 is connected between the two rotating wheels 105 and the transmission shaft 107. The power of the motor 108 is used to drive the rotating wheels 105 to rotate. When the rotating wheels 105 rotate, the protrusions on both sides will drive the second filter frame 306 to lift. After the protrusions pass through the convex blocks 305, the second filter frame 306 will fall. Repeating like this, the second filter frame 306 is always kept vibrating to perform secondary filtering on the cement blocks. The filtered cement slag will fall into the inside of the storage frame 308. The spraying mechanism 2 is beneficial to spraying the cement blocks during filtering, reducing dust and pollution to the environment.
