Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete mixer technology, and in particular to a concrete mixer. Background Technology
[0002] The purpose of a concrete mixer is to mix mud, sand, gravel, and some chemicals to achieve uniform dispersion of the materials. However, current concrete mixing equipment is not well-designed, resulting in the inner wall of the mixing chamber becoming covered with concrete due to prolonged mixing, which cannot be discharged from the outlet. This requires manual removal, which is time-consuming and labor-intensive. Furthermore, there is a possibility that the concrete near the inner wall of the mixing chamber may not be mixed evenly.
[0003] A concrete mixer is disclosed in the prior art patent application with publication number CN 222039054 U. In this utility model, a crossbar is provided, which facilitates the rotation of the first scraper blade and the second scraper blade. During use, the rotation of the first rotor causes the crossbar to rotate, which in turn drives the rotation of the first scraper blade and the second scraper blade. This makes them rotate in the opposite direction to the mixer during operation, simplifying the mixing process and ensuring that the concrete is mixed evenly.
[0004] After the concrete is mixed, the mixing chamber needs to be cleaned in time. However, in the existing technology, the bottom of the mixing chamber cannot be effectively cleaned. The concrete sticks to the bottom of the mixing chamber, causing the device to malfunction. Utility Model Content
[0005] The purpose of this invention is to provide a concrete mixer that solves the problem that after concrete mixing is completed, the mixing chamber needs to be cleaned in a timely manner. However, in the prior art, the bottom of the mixing chamber cannot be effectively cleaned, and the concrete sticks to the bottom of the mixing chamber, causing the device to malfunction.
[0006] To achieve the above objectives, this utility model provides a concrete mixer, including a mixing chamber and a cleaning mechanism. The cleaning mechanism includes a cover plate, a drive shaft, a rotating plate, two cleaning brushes, two connecting assemblies, a rotating ring, two scrapers, and a flushing assembly. The cover plate is disposed above the mixing chamber. The drive shaft is rotatably connected to the cover plate and extends into the mixing chamber. The rotating plate is fixedly connected to the drive shaft. The two cleaning brushes are respectively fixedly connected to both ends of the rotating plate and slidably connected to the inner sidewall of the mixing chamber. The rotating ring is rotatably connected to the mixing chamber and located at the bottom of the mixing chamber. The two scrapers are respectively fixedly connected to both ends of the rotating ring. The two cleaning brushes are detachably connected to the two scrapers through the two connecting assemblies. The flushing assembly is disposed on the cover plate.
[0007] The connecting component includes a locking block and a locking seat. The locking block is fixedly connected to the cleaning brush and located below the cleaning brush. The locking seat is fixedly connected to the scraper. The locking block is slidably connected to the locking seat and located inside the locking seat.
[0008] The flushing assembly includes an annular water pipe and multiple nozzles. One end of the annular water pipe is fixedly connected to and communicates with the cover plate, and the multiple nozzles are fixedly connected to and communicate with the annular water pipe.
[0009] The rinsing assembly further includes a water outlet pipe and a sealing cap. The water outlet pipe is fixedly connected to the mixing chamber and located below the mixing chamber, and the water outlet pipe is connected to the mixing chamber. The sealing cap is threadedly connected to the water outlet pipe.
[0010] The cleaning mechanism further includes a threaded cylinder, which is fixedly connected to the cover plate and located below the cover plate. The threaded cylinder is threadedly connected to the upper part of the mixing chamber and located inside the mixing chamber.
[0011] This utility model discloses a concrete mixer. A drive motor is externally connected to the drive shaft, controlling its rotation. After mixing cement, when cleaning the mixing chamber, the flushing assembly is activated to rinse the chamber. Then, the drive motor is activated again, driving the drive shaft and the rotating plate to rotate. The rotating plate drives two cleaning brushes to scrub the inner wall of the mixing chamber. Simultaneously, the two cleaning brushes drive two scrapers to rotate, scraping away concrete from the bottom of the mixing chamber. This method effectively cleans the bottom and inner wall of the mixing chamber, preventing concrete from adhering to the bottom and ensuring normal operation. Attached Figure Description

A drive motor 10 is externally connected to the drive shaft 105. 4. The drive motor 104 can control the drive shaft 105 to rotate. After mixing cement with this device, when cleaning the mixing chamber 101, the flushing assembly is activated to flush the mixing chamber 101. Then, the drive motor 104 is activated, driving the drive shaft 105 and the rotating plate 106 to rotate. The rotating plate 106 drives the two cleaning brushes 107 to scrub the inner wall of the mixing chamber 101. At the same time, the two cleaning brushes 107 drive the two scrapers 110 to rotate, scraping away the concrete at the bottom of the mixing chamber 101. In this way, the bottom and inner wall of the mixing chamber 101 are effectively cleaned, preventing concrete from sticking to the bottom of the mixing chamber 101 and ensuring that the device can be used normally.

The shaft 105 and the rotating plate 106 rotate, and the rotating plate 106 drives the two cleaning brushes 107 to scrub the inner wall of the mixing chamber 101. At the same time, the two cleaning brushes 107 drive the two scrapers 110 to rotate, and the two scrapers 110 scrape off the concrete at the bottom of the mixing chamber 101. The concrete scraped off from the mixing chamber 101 is discharged through the water outlet pipe 115. In this way, the bottom and inner wall of the mixing chamber 101 are effectively cleaned, preventing concrete from sticking to the bottom of the mixing chamber 101 and ensuring that the mixing chamber can be used normally.
[0027] After mixing cement using this invention, when cleaning the mixing chamber 101, the water pump 112 is started. The water pump 112 delivers high-pressure water to the annular water pipe 113 and multiple nozzles 114. The high-pressure water washes the mixing chamber 101. Then, the drive motor 104 is started, which drives the drive shaft 105 and the rotating plate 106 to rotate. The rotating plate 106 drives two cleaning brushes 107 to scrub the inner wall of the mixing chamber 101. At the same time, the two cleaning brushes 107 drive two scrapers 110 to rotate.
