The mixer is mainly suitable for mixing UHPC concrete, and is also suitable for mixing other types of concrete.

[0035] like Figure 1 , Figure 2 , Figure 7 , Figure 8 As shown, the mixer includes a frame 1, a mixing bin 2 and a material receiving turntable 3. The frame 1 is an integral support of the mixer, which is used to install various components. The mixing bin 2 is a bin structure, and a stirring device is arranged in the mixing bin 2, and the concrete material is stirred by the stirring device. A discharge port is arranged at the lower part of the mixing bin 2 for discharging the concrete material. A material receiving turntable 3 is also hingedly arranged on the frame 1, and the material receiving turntable 3 can rotate on the frame 1. A plurality of material receiving hoppers 4 are arranged on the material receiving turntable 3. Usually, the mixing bin 2 and the material discharge place are respectively located at different positions on the frame 1. After the material receiving turntable 3 receives the concrete material from the mixing bin 2, it is transferred to the material discharge place by rotation, and the concrete material is placed in a specific template. The material receiving hopper 4 on the material receiving turntable 3 is used to contain the concrete material. The material receiving hopper 4 is a quantitative container, and then, the material receiving turntable 3 can realize the quantitative transportation of the concrete material through the material receiving hopper 4.

[0036] In a specific implementation, the frame 1 is usually formed by splicing and connecting square tubes, which can ensure a stable connection and is easy to transport and disassemble.

[0037] like Figure 4 As shown, the mixer is provided with a stirring device in a mixing bin 2, and the stirring device is continuously stirred during operation. Specifically, the upper part of the mixing bin 2 is a cylindrical structure, and the lower part is a conical structure. The stirring device in the mixing bin 2 includes a stirring shaft 8 driven by a motor, and a plurality of stirring blades 9 are fixedly arranged on the stirring shaft 8. The stirring blades 9 are fan blade structures, and preferably, the core of the stirring blades 9 is a hollow structure. Further, preferably, the stirring blades 9 are driven by a hydraulic motor, and the speed of the stirring blades 9 is 0-45 rpm and can be adjusted by a hydraulic station. The stirring blades 9 can rotate clockwise or counterclockwise. The large torque of the hydraulic motor can easily stir the concrete in the silo to prevent the concrete from solidifying.

The material receiving turntable 3 is suspended and hingedly arranged on the frame 1, and the material receiving turntable 3 is installed on the frame 1 through a rotating support. The material receiving turntable 3 can rotate around the central axis under the drive of the driving mechanism. Preferably, the material receiving turntable 3 is driven to rotate using a gear toothed disc driving mechanism. More specifically, the gear toothed disc driving mechanism includes a toothed disc 5 and a driving gear 6. A toothed disc 5 is arranged on the outer edge surface of the material receiving turntable 3, and a driving gear 6 is arranged on the frame 1, so that the driving gear 6 is engaged with the toothed disc 5 for driving. The driving gear 6 is driven by a motor and a reducer; the output end of the motor is dynamically connected to the input end of the reducer, and the output shaft of the reducer is installed with the driving gear 6.

[0039] In order to keep the material receiving turntable 3 stable during rotation, an auxiliary gear 7 is also provided on the frame 1. The auxiliary gear 7 is also meshed with the toothed disc 5, and the auxiliary gear 7 is installed on the frame 1. The auxiliary gear 7 is unpowered. The auxiliary gear 7 is provided on the opposite side of the driving gear 6, so as to stabilize the rotation of the material receiving turntable 3. Figure 5 shown.

[0040] A plurality of receiving hoppers 4 are mounted on the receiving turntable 3. The receiving hoppers 4 are set as quantitative containers to achieve quantitative delivery of concrete materials. The capacity of the receiving hoppers 4 is generally between 7 liters and 15 liters.

[0041] Usually, the receiving hopper 4 is installed on the receiving turntable 3 in a detachable manner, and the receiving hopper 4 of suitable capacity can be replaced when used as needed. The preferred shape and structure of the receiving hopper 4 is cylindrical, and a rectangular structure can also be used. An opening is set on the receiving turntable 3, and the receiving hopper is installed at the opening.

The opening and closing plate 10 is used to control the opening and closing of the drop opening at the lower part of the receiving hopper 4 to discharge the material. The opening and closing plate 10 is arranged at the lower drop opening of the receiving turntable 3. An opening and closing drive cylinder 11 is also arranged corresponding to the opening and closing plate 10, and the opening and closing drive cylinder 11 drives the opening and closing plate 10 to move linearly, thereby realizing the opening and closing control of the drop opening of the receiving hopper 4. Specifically, the opening and closing plate 10 is fixedly mounted on the moving end of the opening and closing drive cylinder 11. The lower end surface of the discharge port of the mixing bin 2 is aligned with the upper end surface of the receiving turntable 3.

[0043] The receiving hopper 4 of the mixer is designed to achieve quantitative feeding. Considering that the concrete material may stick to the inner wall of the receiving hopper 4, a scraping device is required to scrape off the concrete material stuck to the inner wall of the receiving hopper 4. Specifically, a material scraping device is provided on the frame 1 at the material discharge position. The material scraping device mainly includes a scraper 12. A lifting cylinder 13 is provided on the frame 1, and the scraper 12 is fixed to the moving end of the lifting cylinder 13. The scraper 12 is driven up and down by the lifting cylinder 13.

When the scraper 12 moves downward, it can scrape off the concrete material in the receiving hopper 4. Specifically, Figure 1 , Figure 2 shown.

[0044] In the schematic diagram, two receiving hoppers 4 are provided. After one of the receiving hoppers 4 is full of materials, the turntable rotates 180°, and the other receiving hopper 4 receives materials. At this time, the door of the first receiving hopper 4 is opened, and the concrete material is discharged to the prefabricated template. The material scraping device starts to scrape the residual material at the material port, ensuring the accuracy of the concrete volume. After the material in the first receiving hopper 4 is discharged, the door is closed, and the receiving turntable rotates back 180°. At this time, the second receiving hopper 4 is already in the discharge position and can discharge materials... The whole set of actions runs in a cycle. The prefabricated template is generally a square shell structure. When in use, a conveyor belt is set below the material port, and multiple prefabricated templates are set at intervals on the conveyor belt. The conveyor belt transports the prefabricated template, transports the empty prefabricated template to the material drop, and then transports it forward after it is filled with concrete material.

The atomizing device is provided for replenishing water by spraying water to the concrete material in the mixing bin 2.
