[0035] When the mixing device is in use, the staff transports the concrete raw materials such as water, aggregate, gel, etc. into the screening frame 6 through the transportation equipment, and contacts the sieve plate 7. At the same time, the vibration motor is started, and the vibration motor drives the sieve plate 7 to screen the concrete raw materials, screen out the debris, and facilitate the subsequent mixing of the raw materials. The screened raw materials enter the mixing barrel 2 through the connecting pipe and the telescopic pipe 11. At the same time, the drive motor 4 is started, and the drive motor 4 rotates to drive the stirring rod 9 to rotate, so that the stirring blade 10 mixes the concrete raw materials. Through the stirring mechanism, it is convenient to improve the mixing effect of the raw materials, reduce the contamination of the raw materials on the inner wall of the mixing barrel 2, and reduce the waste of raw materials and uneven mixing.

The fixed tube 18 is trumpet-shaped, and the fixed plate 17 is located inside the fixed tube 18.

[0037] When the mixing device is in use, the drive motor 4 is started, and the drive motor 4 rotates to rotate the gear 12, and the gear 12 drives the two gears 2 13 to rotate. The rotation of the gear 2 13 causes the stirring rod 2 14 to rotate. The diameters of the gear 12 and the gear 2 13 are different, and the rotation directions are opposite, so that the stirring rod 2 14 and the stirring blades 10 on the stirring rod 1 9 rotate alternately, which is convenient for uniform mixing of the concrete raw materials and improving the mixing effect. At the same time, the stirring rod 1 9 drives the fixed frame 15 to rotate, so that the fixed frame 15 drives the scraper 25 to rotate, scraping the inner wall of the mixing barrel 2 to reduce the contamination of the raw materials and facilitating the uniform mixing of the raw materials. At the same time, the stirring rod 1 9 drives the fixed plate 17 to rotate, and the fixed plate 17 rotates to cooperate with the fixed pipe 18 to facilitate the discharge of the concrete raw materials and reduce the residue of the raw materials. Through the stirring mechanism, it is convenient to improve the mixing effect of the raw materials, reduce the contamination of the raw materials on the inner wall of the mixing barrel 2, and reduce the waste of raw materials and uneven mixing.

[0038] Reference Figure 1 and Figure 4 The four corners of the lower end of the screening frame 6 are fixed with limiting columns 19. The lower ends of the limiting columns 19 are slidably arranged with the frame 1. The limiting columns 19 are sleeved with springs 20. The ends of the springs 20 are fixedly connected to the screening frame 6 and the frame 1. One end of the screening frame 6 is hinged with a hinge plate 24, and a handle is fixed on the hinge plate 24.

The collection pipe 22 corresponds to the screen plate 7. A filter 23 is set in the fan 21. An air outlet is fixed to the end of the fan 21 away from the collection pipe 22.

[0039] When the mixing device is in use, when the vibration motor is started, the vibration motor drives the screening frame 6 to vibrate, so that the screen plate 7 vibrates, which is convenient for vibrating and screening the raw materials. The telescopic tube 11 is a metal hose that is telescopic. At the same time, the limiting column 19 slides in the frame 1, so that the spring 20 is telescopic. The elasticity of the spring 20 facilitates the vibration screening of the screen plate 7. After the screening is completed, the hinged plate 24 is opened to facilitate the cleaning of the remaining debris after the screening. The inclined screen plate 7 facilitates the screening of the raw materials and the cleaning of the debris. At the same time as the screening, the fan 21 is started, and the fan 21 generates suction.

At the same time, the vibration motor is started, which drives the sieve plate 7 to screen the concrete raw materials and screen out impurities to facilitate the subsequent mixing of raw materials. The screened raw materials enter the mixing barrel 2 through the connecting pipe and the telescopic pipe 11. At the same time, the drive motor 4 is started, and the rotation of the drive motor 4 drives the stirring rod 9 to rotate, so that the stirring blades 10 mix the concrete raw materials.

[0041] When the mixing device is in use, the drive motor 4 is started, and the drive motor 4 rotates to rotate the gear 12, and the gear 12 drives the two gears 2 13 to rotate, and the rotation of the gear 2 13 causes the stirring rod 2 14 to rotate. The diameters of the gear 12 and the gear 2 13 are different, and the rotation directions are opposite, so that the stirring rod 2 14 and the stirring blades 10 on the stirring rod 1 9 rotate alternately, which is convenient for uniform mixing of the concrete raw materials and improves the mixing effect. At the same time, the stirring rod 1 9 drives the fixed frame 15 to rotate, so that the fixed frame 15 drives the scraper 25 to rotate, scraping the inner wall of the mixing barrel 2, reducing the contamination of the raw materials and facilitating the uniform mixing of the raw materials. At the same time, the stirring rod 1 9 drives the fixed plate 17 to rotate, and the fixed plate 17 rotates to cooperate with the fixed pipe 18, which is convenient for the discharge of the concrete raw materials and reduces the residue of the raw materials.

[0042] When the mixing device is in use, when the vibration motor is started, the vibration motor drives the screening frame 6 to vibrate, so that the screen plate 7 vibrates, which is convenient for vibrating and screening the raw materials. The telescopic tube 11 is a metal hose that is telescopic. At the same time, the limiting column 19 slides in the frame 1, so that the spring 20 is telescopic. The elasticity of the spring 20 facilitates the vibration screening of the screen plate 7. After the screening is completed, the hinged plate 24 is opened to facilitate the cleaning of the remaining debris after the screening. The inclined screen plate 7 facilitates the screening of the raw materials and the cleaning of the debris. At the same time as the screening, the fan 21 is started, and the fan 21 generates suction. The suction passes through the collection pipe 22 to inhale the generated dust. The inhaled dust is blocked and filtered by the filter screen 23, and the air is discharged from the air outlet to reduce the impact of the dust on the surrounding environment and the staff.
