Technical Field

[0001] This utility model relates to the field of crushing equipment technology, specifically to a crushing equipment for producing recycled brick aggregate from waste concrete. Background Technology

[0002] Waste concrete aggregate crushing equipment is a mechanical device used to crush waste concrete blocks into recycled aggregates. It is widely used in construction waste treatment and resource recycling.

[0003] Common waste concrete aggregate crushing equipment in existing technologies includes jaw crushers, impact crushers, and double roll crushers. However, these crushing devices produce larger, unqualified fragments when crushing waste concrete blocks. This requires filtration to feed the larger fragments into other crushers for further crushing. In addition, these existing crushing devices require additional screening equipment and cannot be linked, making the overall operation of the device cumbersome. Therefore, an improved waste concrete aggregate crushing equipment for making recycled bricks is needed to address this problem. Utility Model Content

[0019] Please see Figure 1-3 This utility model provides a technical solution: a crushing device for aggregates in the production of recycled bricks from waste concrete, comprising a fixed frame 1. A crushing mechanism for crushing waste concrete is provided on one side of the upper end of the fixed frame 1. The crushing mechanism includes a crushing chamber 2, crushing rollers 3, and a discharge port 4. The crushing chamber 2 is fixedly installed on one side of the upper end of the fixed frame 1. Crushing rollers 3 are movably installed on both sides of the inside of the crushing chamber 2 via rotating shafts. The discharge port 4 is fixedly installed at the lower end of the crushing chamber 2. A screening machine for screening the crushed material is provided on one side of the discharge port 4 on the surface of the fixed frame 1. The screening mechanism includes a chute 5, a slider 6, a screening frame 7, a rotating disk 8, and a transmission rod 9. The fixed frame 1 has a chute 5 in the middle of its surface. The slider 6 is movably engaged inside the chute 5. The screening frame 7 is fixedly arranged between the sliders 6. The rotating disk 8 is movably arranged on one side of the fixed frame 1 via a rotating shaft. The transmission rod 9 is movably arranged on the outer surface of the rotating disk 8 via a rotating shaft. The end of the transmission rod 9 near the slider 6 is movably connected to the slider 6 via the rotating shaft. A transmission mechanism for power transmission is provided on one side of the fixed frame 1.

[0020] The transmission mechanism includes a motor 10, a first pulley 11, a first transmission belt 12, a second pulley 13, and a second transmission belt 14. The motor 10 is fixedly installed on one side inside the fixed frame 1. The first pulley 11 is fixedly installed on both the power output shaft end of the motor 10 and one end of the crushing roller 3. The first transmission belt 12 is sleeved between the first pulleys 11. The second pulley 13 is fixedly installed on one side of the power output shaft end of the motor 10 and the rotating disk 8. The second transmission belt 14 is sleeved between the second pulleys 13. Through the transmission mechanism, the crushing roller 3 can be driven to rotate and crush concrete, and the rotating disk 8 can also be driven to rotate. This can drive the slider 6 and the crushing frame to move back and forth continuously. In this way, the continuously moving crushing frame can improve the screening efficiency and screening effect.

[0021] Inside the fixed frame 1, a support rod 15 is movably installed at the lower end of the screening box 7 via a rotating shaft. The support rod 15 can also support the fixed frame 1, reducing the stress on the slider 6.

[0022] A gear 16 is fixedly provided at one end of the crushing roller 3. The gears 16 mesh with each other and can link the two crushing rollers 3 together.

[0025] Working principle: When using this device, the motor 10, the first pulley 11, the first transmission belt 12, the second pulley 13, and the second transmission belt 14 drive the crushing roller 3 and the rotating disk 8 to rotate respectively. When the crushing roller 3 rotates, the convex teeth on the surfaces of the two relatively rotating crushing rollers 3 can crush the waste concrete. The crushed pieces can enter the upper end of the screening frame 7 through the discharge port 4. Then, the crushing frame can be continuously moved back and forth to screen the crushed pieces. This constitutes a complete crushing process. In this way, the device integrates the roller crusher and the screening equipment, making the device compact and easy to transport to the construction site for use.

[0026] Furthermore, this device is easy to use, as it links the screening frame 7 and the crushing roller 3 together without requiring any other operations. The entire device can be controlled simply by controlling one motor 10, which makes it easy to promote and use.
