Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction equipment technology, specifically to a concrete mixer that can enhance the performance of recycled aggregates. Background Technology
[0002] Recycled aggregates refer to recyclable materials formed by processing waste concrete blocks or other construction wastes through a series of specific processes and screening. Recycled concrete refers to green and environmentally friendly concrete made using recycled aggregates. Using recycled aggregates to make recycled concrete can not only reduce the pollution of construction waste to the environment, but also reduce the construction industry's dependence on natural resources, thus achieving sustainable development.
[0003] Using screened recycled aggregates in concrete production reduces the mechanical properties of the concrete. However, mechanically activating the aggregates before using them in concrete preparation significantly improves their strength. Mechanically strengthening recycled aggregates before their use in the construction industry can not only solve the problem of construction waste accumulation but also achieve resource conservation and ensure mechanical properties, offering broad benefits and promising prospects. Currently, the processing and transportation methods are cumbersome, requiring the aggregates to be transported to separate aggregate strengthening equipment for strengthening before being transported to the application site. This increases the cost of use and hinders the widespread use of recycled aggregates. Therefore, there is a need for an integrated equipment that combines aggregate strengthening and concrete mixing.

[0025] The material conveying device includes a side guard 301, a discharge plate 302, a screen 303, a screen fixing port 304, a baffle 305, a baffle hinge shaft 306, a fixing rope 307, and a baffle fixer 308. The side guard 301 is located on both sides of the discharge plate 302, which is located below the cylinder 101. The screen 303 can be placed on the discharge plate 302 through the screen fixing port 304. The baffle 305 is located at the bottom edge of the screen 303. The baffle hinge shaft 306 connects the screen 303 and the baffle 305. The fixing rope 307 is located on the baffle 305, and the baffle fixer 308 is located at the bottom end of the discharge plate 302.
[0026] The control device includes a control panel 401, a control line 402, a connecting shaft 403, and a motor 404. The control panel is located above the support platform 201.

[0029] The concrete mixer mentioned in this utility model can enhance the performance of recycled aggregates. In specific use, first unscrew the screws 104 on the arc-shaped cover plate 103, open the arc-shaped cover plate 103 with the handle 105, and form an inlet through the hinge shaft 102 of the arc-shaped cover plate. Put the recycled aggregate and steel balls into the cylinder 101 together, close the arc-shaped cover plate 103 with the handle 105, and use the screws 104 to firmly fix the arc-shaped cover plate 103 to the cylinder 101. At the same time, rotate the cleaning port cover plate 106 onto the cleaning port 107 to prevent particles from falling from the cleaning port 107 when the equipment is running.
[0030] Then, the rotation speed and number of rotations are set via the control panel 401. The equipment automatically stops after completing the set parameters. At this point, the screen 303 is placed on the discharge plate 302 along the screen fixing opening 304. After installation, the screws 104 are removed, and the arc-shaped cover plate 103 is opened to form an outlet. Using the control panel 401, the outlet of the cylinder 101 is aligned with the discharge plate 302 to pour out the recycled aggregate. The recycled aggregate then rolls and displaces along the screen 303, which has a certain angle of inclination. Its particle size... Fine particles with a diameter d ≤ 5 mm are collected into the screen 303 by the screening device and converge at the baffle 305. Recycled aggregate with a diameter d > 5 mm and steel balls converge at the bottom of the discharge plate 302 and fall down along the inclined direction of the discharge plate 302. At this time, the fixing rope 307 fixed at the baffle fixing device 308 can be removed and the baffle 305 can be lifted. The baffle 305 will rotate around the baffle hinge shaft 306, which can collect fine particles with a diameter ≤ 5 mm collected in the screen 303.
[0031] After collection, the screen 303 is removed along the screen fixing port 304, and the cylinder 101 and the discharge plate 302 are cleaned. The water pressure and water flow rate are adjusted on the control panel 401, the cleaning port cover 106 is opened, and the head of the infusion pipe 504 is rotated to form a cleaning nozzle and inserted into the cleaning port 107 for cleaning. At this time, water is transferred from the water tank 501 along the inlet pipe 502 through the water controller 503 to the infusion pipe 504. The cleaned water flows out from the discharge plate 302 through the outlet.
[0032] After all excess water has drained out and the surface remains moist, insert the stirring shaft 602 into the cylinder 101 through the inlet along the track groove 110. When the stirring shaft 602 is flush with the end of the connecting shaft 402, use the buckle 108 and the retainer 109 to restrict the displacement of the stirring shaft 602. At this point, the reinforced recycled aggregate can be placed into the cylinder 101 through the inlet. Close the arc-shaped cover plate 103 with the handle 105 and use the screws 104 to firmly fix the arc-shaped cover plate 103 to the cylinder 101. At the same time, rotate the cleaning port cover plate 106 onto the cleaning port 107 to prevent particles from falling from the cleaning port 107 during equipment operation. Set the rotation speed and rotation time on the control panel 401. Once the equipment completes the set parameters and stops automatically, open the cleaning port cover 106, insert the infusion tube 504, and input the mixing ratio water volume on the control panel 401. After completion, the water controller 503 draws water from the water tank 501 according to the input weight and inputs it into the cylinder 101. When the specified input volume is completed, the water controller 503 stops automatically. At this time, pull out the infusion tube 504, rotate the cleaning port cover 106 to the cleaning port 107, and continue to set the rotation speed and rotation time on the control panel 401. After completion, remove the screw 104, open the arc-shaped cover 103, and use the control panel 401 to align the outlet with the discharge plate 302. At this time, the concrete is collected into the container along the discharge plate 302.
[0033] After the above operations are completed, the inside of the cylinder 101 is cleaned. The water pressure and water flow rate are adjusted on the control panel 401, the cleaning port cover 106 is opened, the head of the infusion tube 504 is rotated to form a cleaning nozzle and inserted into the cleaning port 107 for cleaning. The cleaned water flows out from the discharge plate through the outlet.

Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
