[0002] Concrete is a general term for engineering composite materials composed of aggregates bonded together by a cementitious material. The term generally refers to cement as the binder, sand and stone as aggregates, mixed with water (optionally with admixtures and additives) in a specific proportion, and then mixed together to create cement concrete, also known as conventional concrete. It is widely used in civil engineering. A concrete mixer is a machine that mixes cement, sand and stone aggregates, and water to create the concrete mixture. Concrete mixers require regular cleaning, but existing concrete mixers are difficult to disassemble and disassemble due to their heavy components, making cleaning the interior of the concrete mixer very cumbersome and inconvenient for subsequent use.

A support plate 802 is fixedly connected to the lower part of the second guide plate 8. The right side of the support plate 802 is rotatably connected to the screw rod 803, the top of the screw rod 803 is fixedly connected to the hand wheel disc 804, the bottom end of the screw rod 803 is fixedly connected to the support foot 2, the left side of the support plate 802 is slidably connected to the guide rod 805, the bottom end of the guide rod 805 is fixedly connected to the support foot 2, the middle bottom end of the support plate 802 is fixedly connected to the discharging port 6, and a valve 601 for switching is provided on the discharging port 6.

[0024] like Figure 2 As shown, a vibration motor 9 is also included, and the vibration motor 9 is installed on the outside of the second guide plate 8.

[0025] like Figure 3 As shown, it also includes a scraper 703 and a first fixing screw 704. The scraper 703 is detachably connected to the outside of the stirring rod 701. The scraper 703 matches the shape of the side baffle 111. The scraper 703 and the stirring rod 701 are threadedly connected by the first fixing screw 704.

[0026] like Figure 4 and Figure 5 As shown, it also includes a connecting plate 15, a block 1501, a pull rod 1502, a connecting frame 1503 and an elastic member 1504. The connecting plate 15 is fixedly connected to the baffle 111 on the right side of the material blocking door 5. The connecting frame 1503 is fixedly connected to the right side of the connecting plate 15. The pull rod 1502 is slidably connected in the middle of the connecting frame 1503.

[0028] When using the device, open the material blocking door 5, pour the concrete raw materials into the device from the first material guide plate 4 to the feed port 3, close the material blocking door 5, start the servo motor 7, and the output shaft of the servo motor 7 rotates to drive the connecting rod 702 to rotate, and the connecting rod 702 rotates to drive the stirring rod 701 to rotate to stir the concrete raw materials. When the concrete mixing is completed, during the mixing process, the shock absorber 1 can reduce the vibration amplitude of the device to prevent the device from tipping over during the mixing process. Then open the valve 601 and guide the mixed concrete out of the discharge port 6. When all the raw materials in the device are poured out, water is injected into the water tank 10 from the water inlet 11. Then, the water pump 12 is started, and the water in the water tank 10 flows into the water pipe 13 through the water pump 12, and then flows from the water pipe 13 to the high-pressure nozzle 14. The high-pressure nozzle 14 sprays to clean the stirring rod 701 and the inner wall inside the device. Then, the second fixing screw 801 is twisted to separate the baffle 111 from the second guide plate 8, and the handwheel 804 is rotated. The screw rod 803 rotates accordingly, and the support plate 802 moves downward with the screw rod 803 and the guide rod 805, driving the second guide plate 8 to move downward. The staff can clean the parts that the high-pressure nozzle 14 at the lower end cannot clean. The concrete mixer is cleaned and convenient for next use.

The scraper 703 can scrape off the attachments on the inner wall, making it more convenient for the subsequent high-pressure nozzle 14 to clean the interior. After the scraper 703 is damaged, the first fixing screw 704 can be rotated to replace the scraper 703; when feeding the device , pull the pull rod 1502 outward, the pull rod 1502 drives the block 1501 to move outward, at this time the elastic member 1504 is squeezed, and after the material blocking door 5 is opened, release the pull rod 1502, at this time the elastic member 1504 loses the tension and resets, driving the pull rod 1502 to move inward, driving the block 1501 to move inward, thereby fixing the material blocking door 5 to prevent the material blocking door 5 from falling during the material arrival process; during use, the staff can observe the stirring and cleaning conditions inside the device through the observation window 16.
