[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Please refer to the following: Figure 1 , Figure 2 and Figure 3The system includes: a mixing tank, a cleaning structure, a base plate, and a filter structure. The cleaning structure is located on the upper surface of the mixing tank. As the main container for concrete mixing, the mixing tank provides space for mixing concrete raw materials, ensuring that various materials are thoroughly and evenly mixed. The cleaning structure includes an equipment box, a transmission rod, gears, a rack, a fixing ring, and rubber scrapers. The transmission rod is located inside the equipment box, with both ends rotatably connected to the inner walls on both sides of the box. Gears are fixedly connected to the outer surface of the transmission rod, and a rack meshes with one side of the gears. As a key component for power transmission, the rotation of the transmission rod drives the gears fixedly connected to its outer surface to rotate. Through the meshing relationship between the gears and the rack, the circular motion of the transmission rod is converted into gear rotation. The linear motion of the rack enables the rack to move up and down in conjunction with the gear, thereby driving the cleaning components to clean the inner wall of the mixing drum. The cleaning structure prevents concrete residue from adhering to the inner wall of the mixing drum. A base plate is fixedly connected to the lower end of the mixing drum. An installation groove is opened on the upper surface of the base plate, and a filter structure is installed inside the installation groove. The base plate is the support and installation foundation of the mixing drum, providing stable support for the mixing drum. At the same time, the installation groove is used to install the filter structure, so that the filter structure can function in the appropriate position. The filter structure includes a feed pipe and a spiral auger. The spiral auger is rotated inside the feed pipe. The filter structure is used to separate the liquid and concrete residue in the cleaning fluid used to clean the concrete mixing drum.
[0021] In the specific implementation process, a first discharge pipe and a second discharge pipe are fixedly connected to both sides of the lower end of the mixing tank, respectively. Control valves are installed on the upper surfaces of the first and second discharge pipes. The first discharge pipe is used to discharge the concrete and other materials after mixing, while the second discharge pipe is used to discharge the cleaning fluid used to clean the concrete mixing tank. The control valves installed on the upper surfaces of the first and second discharge pipes can control the opening and closing of the discharge, allowing for flexible material discharge according to actual needs. A mounting plate is fixedly connected to the upper end of the mixing tank, and a drive motor is fixedly connected to the upper surface of the mounting plate. The drive motor is electrically connected to an external power source, and through holes are provided on the upper surface of the mounting plate for installation. A stirring rod is rotatably connected inside the through-hole on the upper surface of the plate. The mounting plate provides a mounting position for the drive motor, and the through-hole is used to rotatably connect the stirring rod, ensuring that the stirring rod can rotate stably within it, thus realizing the stirring function of the materials in the mixing tank. The upper end of the stirring rod is fixedly connected to the power output end of the drive motor, and the lower end of the stirring rod is rotatably connected to the bottom of the mixing tank. The stirring rod rotates under the drive motor. Several sets of stirring blades are fixedly connected to the outer surface of the stirring rod. The stirring blades rotate with the rotation of the stirring rod, breaking up the agglomeration of the materials by continuously stirring them, promoting the full contact and mixing of different raw materials, and achieving the effect of uniform concrete mixing.
[0022] The equipment box has a through hole on one side of its outer surface. The lower surface of the equipment box is fixedly connected to the upper end of the mixing tank. The equipment box provides space for the installation and protection of components such as transmission rods, gears, and racks, enabling them to work together in a relatively stable environment. At the same time, by being fixedly connected to the upper end of the mixing tank, it provides a supporting foundation for the entire cleaning structure. The upper and lower surfaces of the equipment box have through grooves. The upper and lower ends of the rack extend through the through grooves on the upper and lower surfaces of the equipment box to the top and bottom of the equipment box, respectively. The lower end of the rack extends into the interior of the mixing tank. A fixing ring is fixedly connected to the lower end of the rack. The inner diameter of the fixing ring is larger than the diameter of the mixing blade. A rubber scraper is fixedly connected to the outer surface of the fixing ring. The rubber scraper is in contact with the inner wall of the mixing tank. Driven by the gears, the rack moves up and down in a linear motion. The rack can drive the fixing ring and the rubber scraper on it to move up and down, thereby scraping and cleaning the inner wall of the mixing tank and preventing concrete residue from adhering to the inner wall of the mixing tank.
[0023] The transmission rod has a worm gear fixedly connected to its outer surface. The worm gear is coaxial with the gear. When the worm gear rotates, it can drive the transmission rod to rotate, which in turn drives the gear to rotate. A worm is meshed above the worm gear. When the worm rotates, it can drive the worm gear to rotate. One end of the worm is rotatably connected to the inner wall of the equipment box, and the other end of the worm extends through a through hole on one side of the outer surface of the equipment box to the outer surface of the equipment box. A rotating wheel is fixedly connected to the end of the worm that extends to the outer surface of the equipment box. The rotating wheel is easy for the operator to hold and apply rotational torque. By rotating the rotating wheel, the worm is driven to rotate.
[0024] The outer surface of the feed pipe is fixedly connected to the inner wall of the mounting groove on the upper surface of the base plate. Several sets of filter holes are opened on the lower surface of the feed pipe. These filter holes can filter the passing material, allowing water and other liquids to flow out through the filter holes, thus achieving solid-liquid separation. A water collection tank is fixedly connected to the lower surface of the feed pipe. The water collection tank is used to collect the water and other liquids filtered out through the filter holes on the lower surface of the feed pipe, realizing the collection of liquids after solid-liquid separation in the concrete discharge material. This facilitates the recycling and reuse of cleaning fluid and saves water resources. A through hole is opened on the outer surface of one end of the feed pipe, and a feed inlet is opened on the upper surface of one end of the feed pipe. The lower end of the second discharge pipe extends through the feed inlet on the upper surface of the feed pipe into the interior of the feed pipe, allowing the material to smoothly enter and pass through the feed pipe. A discharge port is opened on the lower surface of the other end of the feed pipe.
[0025] One end of the auger is rotatably connected to the inner wall of the discharge port end of the guide pipe, while the other end extends through a through-hole on the outer surface of the guide pipe to the outer surface of the guide pipe. A servo motor is installed at the end of the auger extending to the outer surface of the guide pipe, and the servo motor is electrically connected to an external power source. The power output end of the servo motor is fixedly connected to the end of the auger extending to the outer surface of the guide pipe, and the outer surface of the servo motor is fixedly connected to the inner wall of the mounting groove on the upper surface of the base plate. The servo motor serves as the power source for the rotation of the auger, driving it to rotate inside the guide pipe. The rotation of the auger, driven by the servo motor, can push the material entering the guide pipe from one end to the other, facilitating the smooth discharge of the material from the discharge port and preventing blockage inside the guide pipe. At the same time, the process of pushing the material to move also helps the friction between the material and the inner wall of the guide pipe, further promoting the filtration effect.
[0026] The working principle of this utility model is as follows: During concrete mixing, the drive motor is powered on, and its power output drives the mixing rod to rotate. The mixing blades on the outer surface of the mixing rod rotate accordingly, fully mixing the concrete raw materials in the mixing drum, so that the various materials are evenly mixed to form concrete that meets the requirements. After mixing is completed, the control valve on the first discharge pipe can be opened to discharge the mixed concrete. When it is necessary to clean the mixing drum, cleaning fluid can be injected into the mixing drum through an external water source. Then, the cleaning structure is activated. The operator holds the rotating wheel and applies a rotational torque to make the worm gear rotate. The worm gear drives the worm wheel meshing with it to rotate, which in turn drives the transmission rod to rotate. The gear on the transmission rod rotates accordingly, and the rack meshing with the gear moves up and down linearly in the through groove of the equipment box. The fixing ring at the lower end of the rack and the rubber scraper on its outer surface move together with the rack, stirring the mixing drum. The inner wall of the mixing drum is scraped and cleaned to remove the attached concrete residue. The cleaning liquid containing the residue can be discharged into the feed pipe by opening the control valve of the second discharge pipe. Inside the feed pipe, the servo motor is powered on and drives the auger to rotate. The auger pushes the cleaning liquid and residue toward the discharge port. During this process, the liquid in the cleaning liquid flows into the water collection tank for recycling through the filter holes on the lower surface of the feed pipe, while the concrete residue is discharged from the discharge port by the auger. This achieves solid-liquid separation of the cleaning liquid and discharge of the residue after cleaning.
