Description

Technical Field

[0001] This utility model relates to the field of concrete aggregate technology, specifically to a concrete aggregate processing device. Background Technology

[0002] Concrete aggregates refer to granular loose materials that serve as the skeleton or filler in concrete. They are divided into coarse aggregates and fine aggregates. Coarse aggregates refer to pebbles, crushed stone, etc., while fine aggregates refer to natural sand, artificial sand, etc.

[0003] The existing authorized publication number "CN216224691U" describes a recycled concrete aggregate processing device, which includes a processing unit. A motor is fixedly connected to the top wall of the processing unit. An output shaft is located on the lower outer surface of the motor, and crushing blades are welded to the outer surface of the output shaft. A raised block is fixedly connected to the bottom wall of the processing unit. A hydraulic cylinder is fixedly connected to the upper surface of the raised block. A lifting column is located on the upper outer surface of the hydraulic cylinder. A fixed plate is fixedly connected to the upper outer surface of the lifting column. A spring is located on the upper surface of the fixed plate. A screen is located at the end of the spring furthest from the fixed plate. A vibrator is located in the middle of the lower surface of the screen. The combination of the spring, screen, and vibrator vibrates and sorts the crushed raw material, causing smaller particles of concrete aggregate to fall onto the bottom inner wall of the processing unit, thereby improving the sorting efficiency during the crushing and processing of recycled concrete aggregate.

[0004] However, common aggregates are rocks or pebbles, and this device cannot effectively crush these materials, thus failing to ensure that the aggregate particles are of consistent size after crushing. This affects the subsequent use of the aggregates, and the device cannot guarantee crushing efficiency during the crushing process. Utility Model Content

The vibration force during the up and down movement can be used to screen the aggregate to prevent large particles from being mixed with normal particles. Then, with the cooperation of the roller, conveyor belt, hopper, feeding bin and discharge port, these large particles of aggregate can be transported back to the crushing area for further crushing, thereby improving the convenience of recycling.

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.

[0022] Please see Figures 1-4The present invention provides an embodiment of a concrete aggregate processing device, comprising an installation chamber 1, wherein guide plates 13 are symmetrically arranged on the top of both sides of the installation chamber 1, and the guide plates 13 are obliquely arranged downward inside the installation chamber 1, so that the aggregates can be concentrated at the rotating drum 5 for crushing. A feeding chamber 10 is provided at the bottom of one side of the installation chamber 1, and a through groove is provided between the installation chamber 1 and the feeding chamber 10. An inclined guide plate is provided on one side of the bottom of the feeding chamber 10 to guide the aggregates falling down and facilitate the filling of the aggregates. Rotary wheels 7 are symmetrically arranged at the top and bottom of one end of the feeding chamber 10, and a conveyor belt 8 is provided between the outer sides of the two sets of rotating wheels 7. Multiple sets of hoppers 9 are evenly arranged on the outer side of the conveyor belt 8. A first drive motor 19 is provided at the bottom of one end of the feeding chamber 10, and a discharge port 11 is provided at the top of one side of the feeding chamber 10.

[0023] A screen 4 is hinged to the middle of one side of the installation chamber 1. A rotating shaft 2 is provided on one side of the bottom of one end of the installation chamber 1. A cam 3 is provided on the outside of the rotating shaft 2. A hinge frame is provided in the middle of one side of the installation chamber 1. The screen 4 is located inside the hinge frame. A sliding plate is provided on one side of the bottom of the screen 4. During the rotation of the cam 3, the sliding plate is pushed to push the screen 4 to reciprocate, avoiding direct disengagement from the screen 4. A second drive motor 21 is provided at the bottom of one side of the installation chamber 1. The output end of the second drive motor 21 is connected to the rotating shaft 2. Rotating rods 6 are symmetrically provided on both sides of the top of one end of the installation chamber 1. Both ends of the installation chamber 1 are provided with mounting holes. The rotating rods 6 extend to the outside through the mounting holes for easy connection. A rotating cylinder 5 is provided on the outside of the rotating rods 6. A servo motor 20 is provided on one side of the top of one end of the installation chamber 1. The output end of the servo motor 20 is connected to the rotating rods 6. One end of the rotating rods 6 extends to the outside of the installation chamber 1 and is provided with a gear 22. Baffles 12 are symmetrically provided at both ends of the top of the installation chamber 1.

[0024] The installation chamber 1 has a liquid infusion cooling chamber 15 on one side. The cooling chamber 15 is equipped with a first conveyor belt 14 inside. The cooling chamber 15 is equipped with a heating chamber 16 on one side of the top. The bottom of both the cooling chamber 15 and the heating chamber 16 is equipped with support legs. Triangular reinforcing plates are provided between the cooling chamber 15 and the heating chamber 16 and between the cooling chamber 15 and the first conveyor belt 14 to ensure the strength of the support. The bottom of the interior of the heating chamber 16 is equipped with a second conveyor belt 17, and the top of the interior of the heating chamber 16 is equipped with a heating device 18.

[0025] Working principle: In the aggregate processing process, the stones are first fed to the second conveyor belt 17, and then the stones are conveyed on the top of the second conveyor belt 17. During the conveying process, the heating device 18 heats the stones at high temperature, so that the stones heat up quickly. After heating, the stones fall into the cooling chamber 15. The cooling water inside the cooling chamber 15 quickly lowers the temperature of the stones, and the stones become brittle due to thermal expansion and contraction.

[0026] The brittle stones are conveyed to the guide plate 13 by the first conveyor belt 14, and slide down the guide plate 13 to the rotating drum 5 for crushing and fall onto the screen 4. At this time, the second drive motor 21 is started. The second drive motor 21 drives the rotating shaft 2 and the cam 3 to rotate. During the rotation, the cam 3 pushes the screen 4. The screen 4 moves up and down back and forth under the action of gravity and the cam 3, thereby screening the aggregate. The aggregate with qualified particle size slides down the hole to the bottom of the installation bin 1, while the large aggregate slides down the inclined surface of the screen 4 into the inside of the feeding bin 10.

[0027] When these aggregates enter the inside of the feeding hopper 10, the first drive motor 19 is started. The first drive motor 19 drives the rotating wheel 7 to rotate, and then the rotating wheel 7 drives the conveyor belt 8 to move. At this time, the conveyor belt 8 loads these large aggregate particles into its interior and conveys them. During the conveying process, the hopper 9 moves to the top. At this time, these aggregates fall into the inside of the discharge port 11 under the action of gravity, and then move to the rotating drum 5 to be crushed again.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
