[0002] In bridge construction, concrete is usually poured for construction. The concrete residue generated during the process is a valuable resource, so it can be recycled and reused, thereby reducing construction costs and environmental pollution at the same time.

[0003] A concrete residue recycling mechanism for bridge construction with the publication number of CN219850661U has a box body as the main body. A feed hopper is fixed on the top side of the box body, a discharge pipe is fixed on the bottom side of the box body, two filter meshes are fixed on the inner side of the box body, an anti-blocking component is arranged on the inner side of the box body, a motor is fixed on the top side of the box body, a first rotating rod is fixed on the output shaft of the motor, a scraper is fixed on the circumferential surface of the first rotating rod, and a fixed bin is fixed on the bottom side of the filter mesh. By setting the anti-blocking component, the motor is controlled to drive the scraper to rotate, so as to scrape the materials blocking the surface of the filter mesh. At the same time, the impact rod impacts the filter mesh to make it vibrate, making the device less likely to be blocked.

[0004] There are still problems in the above-mentioned concrete residue recycling mechanism for bridge construction. It only separates the slurry and aggregate by the natural penetration of the slurry through the filter mesh, and the required separation time is relatively long during use, resulting in low recycling efficiency of the recycling mechanism. Therefore, a concrete residue recycling mechanism for bridge construction is proposed. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art, the recycling mechanisms on the market only separate the slurry and aggregate by the natural penetration of the slurry, and the required separation time is relatively long during use, resulting in low recycling efficiency of the recycling mechanism.

The output end of the servo motor passes through the fixed platform and is fixed to the small belt pulley. An inlet is opened at the top end of the tank body. A scraper is slidably installed inside the tank body. Through the structure of the filter barrel, during the rotation process, the mud is thrown out by centrifugal force, so as to separate the aggregate from the mud, and the separation efficiency is higher.

[0008] Preferably, the cleaning mechanism includes a scraper. The scraper is closely attached to the inner surface of the tank body and the outer surface of the filter barrel. Cylinders are symmetrically fixed at both ends of the top side of the tank body. A round rod is slidably installed inside the cylinder through a piston. The round rod slidably penetrates through the top side of the tank body. One end of the round rod is fixed to the scraper. A mounting seat is fixed on the circumferential surface of the bottom side of the outlet. The mud attached to the surfaces of the tank body and the filter barrel can be scraped off by the scraper, which is convenient for subsequent cleaning and maintenance.

[0009] Preferably, the fixing mechanism includes a mounting seat. A bottom cover is rotatably installed on the bottom side of the mounting seat. A fixing seat is fixed at one end of the bottom cover. A limit seat is fixed on the circumferential surface of the bottom side of the outlet. A plug rod is slidably penetrated inside the limit seat. A limit cap is fixed at the top end of the plug rod. A spring is fixedly connected between the limit cap and the limit seat. One end of the plug rod is inserted and installed inside the fixing seat.

[0010] The beneficial effects of the present invention are as follows:

[0011] 1. Through the structural design of a concrete residue recycling mechanism for bridge construction, by setting a separation mechanism, controlling the servo motor to drive the small belt pulley at the output end to rotate, and then driving the large belt pulley to rotate under the cooperation of the belt, so that the filter barrel inside the tank body rotates. At this time, the concrete residue is added through the inlet. While the filter barrel rotates, the mud is thrown out by centrifugal force, and at the same time, the aggregate in the residue is filtered out, and the separation efficiency is higher, solving the problem that the separation speed of the existing recycling mechanism is slow, resulting in a decline in the recycling efficiency.

[0012] 2.

An inlet 103 is opened at the top end of the tank body 1, and a scraper 13 is slidably installed inside the tank body 1; during operation, when encountering the problem that the existing recycling mechanism takes a long time to separate mud and aggregates, resulting in a reduction in recycling efficiency, through the structure of the separation mechanism, control the servo motor 9 to drive the small pulley 7 at the output end to rotate. Thus, with the cooperation of the belt 8, drive the large pulley 5 to rotate, so that the filter barrel 3 inside the tank body 1 rotates. At this time, add the concrete residue through the inlet 103. While the filter barrel 3 rotates, the mud is thrown out by centrifugal force, and at the same time, the aggregates in the residue are filtered out, and the separation efficiency is higher.

[0023] Please refer to Figure 3 As shown in the figure, the cleaning mechanism includes a scraper 13, the scraper 13 is in close contact with the inner surface of the tank body 1 and the outer surface of the filter barrel 3. At both ends of the top side of the tank body 1, cylinders 10 are symmetrically fixed. Inside the cylinders 10, round rods 12 are slidably installed through pistons 11. The round rods 12 slide through the top side of the tank body 1, and one end of the round rod 12 is fixed to the scraper 13.

[0026] Working principle: In bridge construction, concrete is usually poured for construction. The surplus concrete generated during the process is a valuable resource. Therefore, it can be recycled and reused, which can reduce construction costs and environmental pollution at the same time. Existing recycling institutions only separate the slurry from the aggregate by the natural penetration of the slurry through the filter screen, and the separation time required during use is relatively long, resulting in low recycling efficiency of the recycling institution. To solve this problem, by setting up a separation mechanism and a cleaning mechanism, control the servo motor 9 to drive the small pulley 7 at its output end to rotate. Thus, with the cooperation of the belt 8, drive the large pulley 5 to rotate, and make the filter barrel 3 inside the tank body 1 rotate. At this time, add the surplus concrete through the feed port 103. While the filter barrel 3 is rotating, the slurry is thrown out by centrifugal force, and at the same time, the aggregate in the surplus material is filtered out. After the separation is completed, turn off the servo motor 9, control the cylinder 10, and make the round rod 12 inside it extend, so as to drive the scraper 13 to slide inside the tank body 1, scrape the slurry on the surfaces of the tank body 1 and the filter barrel 3 to the bottom side of the tank body 1, and make it discharge through the conduit 101. Then pull the limit cap 19 to pull out the insertion rod 18. At this time, the bottom cover 15 can be rotated to open the discharge port 4, so as to discharge the aggregate. After that, close the bottom cover 15, loosen the limit cap 19, and under the action of the elastic force of the spring 20, pull the insertion rod 18 to re-insert and install it inside the fixed seat 16 to fix the position of the bottom cover 15 for the next use, solving the problem that the separation speed of the existing recycling institution is slow, resulting in a decline in recycling efficiency.
