[0022] As a technical optimization solution of the utility model, the widths of the two ends of the baffle plate 3 are smaller than the width in the middle, and a sealing gasket 6 is provided between the baffle plate 3 and the mixing barrel 1, thereby improving the sealing performance between the baffle plate 3 and the mixing barrel 1.
[0023] As a technical optimization solution of the present utility model, two handles 4 are fixedly connected to the baffle 3 , and one end of the cross section of the knob 502 is a hexagonal structure, so the baffle 3 can be easily moved by the handle 4 .
[0024] As a technical optimization solution of the utility model, a positioning groove 503 is provided on the baffle 3, and one end of the knob 502 is located inside the positioning groove 503, so that the positioning of the slide plate 501 can be achieved by making the end of the knob 502 located inside the positioning groove 503.
[0025] As a technical optimization solution of the utility model, the width of the opening 505 is greater than the width of the slide 501, and the inner side of the baffle 3 is flush with the inner wall of the mixing barrel 1, so that the end of the slide 501 can be slid from the opening 505 into the interior of the slide groove 504, thereby realizing the installation of the slide 501.
[0026] As a technical optimization solution of the utility model, the bottom end of the mixing barrel 1 is fixedly connected to a support frame 2, a vibration motor 11 is fixedly installed on the mixing barrel 1, and a material guide hopper 14 is fixedly connected to the mixing barrel 1, so that concrete can easily enter the interior of the mixing barrel 1 through the material guide hopper 14.
[0027] As a technical optimization solution of the utility model, two first butterfly valves 10 are installed inside the mixing barrel 1, one end of the mixing barrel 1 is fixedly connected to a discharge pipe 12, and a second butterfly valve 13 is installed on the discharge pipe 12, so that the discharge of the mixed concrete can be controlled.
[0028] As a technical optimization scheme of the utility model, the mixing barrel 1 is provided with a driving structure 7, and the driving structure 7 includes a motor 701. A plurality of motors 701 are installed on the mixing barrel 1. A first synchronous wheel 702 is fixedly connected to the output shaft of the motor 701. A plurality of connecting shafts 705 are rotatably connected to the mixing barrel 1. A second synchronous wheel 704 is fixedly connected to one end of the connecting shaft 705. A synchronous belt 703 is wound between the second synchronous wheel 704 on a connecting shaft 705 located on one side of the motor 701 and the first synchronous wheel 702 on the output shaft of the motor 701. A first stirring assembly 8 is respectively installed on two of the connecting shafts 705 near one end of the guide hopper 14, and a second stirring assembly 9 is installed on the other connecting shaft 705 near the discharge pipe 12. Therefore, stirring at different levels and speeds can be achieved, thereby effectively improving the stirring effect, while also avoiding damage to the driving motor caused by excessive load when a single driving motor is driven, thereby effectively improving the safety of use.
[0029] When the utility model is in use, when it is necessary to clean the inside of the mixing barrel 1, the knobs 502 can be twisted in sequence by a wrench. When the ends of all the knobs 502 do not conflict with the baffle plate 3, the slide plate 501 can be pushed so that the slide plate 501 does not block the baffle plate 3. Then, the baffle plate 3 can be removed from the mixing barrel 1 by holding the handle 4. After the baffle plate 3 is removed from the mixing barrel 1, a gap will appear on the side wall of the mixing barrel 1. At this time, the staff can extend their body into the mixing barrel 1 through the gap in the side wall of the mixing barrel 1 to clean the inside of the mixing barrel 1, thereby effectively ensuring the cleaning of the inside of the mixing barrel 1 and effectively ensuring the mixing. The baffle 3 is then locked with the mixing barrel 1 by holding the handle 4, and the slide plate 501 can be pushed to cover the baffle 3. As the position of the slide plate 501 changes, the end of the knob 502 will face the positioning groove 503. At this time, the knob 502 can be turned by a wrench. As the knob 502 is continuously turned, the end of the knob 502 will be located inside the positioning groove 503 and abut against the baffle 3. Then, the above operation is repeated so that the ends of all the knobs 502 abut against the baffle 3. At this time, the installation and fixation of the baffle 3 is completed. The sealing gasket 6 can be provided to improve The sealing between the baffle 3 and the mixing barrel 1 can be achieved by the simultaneous rotation of the output shafts of the three motors 701 during use. The rotation of the output shaft of the motor 701 will drive the first synchronous wheel 702 to rotate. The first synchronous wheel 702 drives the second synchronous wheel 704 to rotate through the synchronous belt 703. The rotation of the second synchronous wheel 704 drives the connecting shaft 705 to rotate. The rotation of the two connecting shafts 705 will respectively drive the two first stirring components 8 to rotate, and the rotation of the other connecting shaft 705 will drive the second stirring component 9 to rotate. At this time, the concrete to be stirred can be added from the guide hopper 14 to one end of the mixing barrel 1, and then through one of the first stirring The concrete is stirred by the mixing assembly 8. After the stirring is completed, the concrete will fall into the middle of the mixing barrel 1 and be stirred by another first stirring assembly 8. The re-stirred concrete will fall into the bottom of the mixing barrel 1 and be stirred by the second stirring assembly 9 for the final stirring. After the stirring is completed, it will be discharged from the discharge pipe 12, thereby realizing multi-stage stirring of the concrete. Since the stirring speed of each stage is controlled by a different motor 701, stirring at different levels and speeds can be achieved, thereby effectively improving the stirring effect. At the same time, it also avoids damage to the drive motor due to excessive load when a single drive motor is driven, thereby effectively improving the safety of use.
