For the stirring of the materials, most of the existing technologies directly put the materials into the stirring tank and drive the stirring components to rotate through rotating equipment, so as to realize the mixing of the materials. For the fine stirring of the materials, the stirring blade stirring method is generally adopted. When mixing and stirring the materials, sometimes it is also necessary to add water to realize the mixing of the materials and at the same time achieve the purpose of suppressing dust for the put-in materials.

Stirring rods 11 are fixedly connected to the stirring shaft 10. The stirring rods 11 are arranged inside the stirring tank 1. The stirring tank 1 is a box or cylinder with an open top surface. A top support assembly 3 is connected to the top surface of the stirring tank 1. The top support assembly 3 includes an angle steel support ring 4, columns 5, cross bars 6 and a central plate 18. There are multiple columns 5. Multiple columns 5 are all fixedly connected to the top surface of the angle steel support ring 4. Multiple columns 5 are circumferentially and evenly distributed around the axis of the angle steel support ring 4. There are multiple cross bars 6. The number of multiple cross bars 6 is the same as that of multiple columns 5. Multiple cross bars 6 are respectively fixedly connected to the tops of multiple columns 5. The central plate 18 is fixedly connected to one end of multiple cross bars 6 away from the columns 5. The central plate 18 is coaxial with the angle steel support ring 4. The angle steel support ring 4 is connected to the open top surface of the stirring tank 1. The central plate 18 is arranged above the open top surface of the stirring tank 1. A motor 9 is fixedly connected to the top surface of the central plate 18 facing away from the stirring tank 1. The output shaft of the motor 9 penetrates the central plate 18. There is a hole on the central plate 18 for the output shaft of the motor 9 to pass through. The top end of the stirring shaft 10 is fixedly connected to the output shaft of the motor 9. A filter screen 12 is fixedly connected to the stirring shaft 10. The filter screen 12 is coaxial with the stirring shaft 10. The filter screen 12 is arranged inside the stirring tank 1. The filter screen 12 is arranged above the stirring rods 11. The filter screen 12 is close to the open top surface of the stirring tank 1. A rib plate 7 is fixedly connected between each column 5 and each cross bar 6. The rib plate 7 is triangular.

[0025] When the present utility model is in use, building materials or water are added through the open top surface of the stirring tank 1. The setting of the top support assembly 3 does not affect the addition of building materials. There is space between multiple columns 5 for adding building materials or water. The motor 9 drives the stirring shaft 10 to rotate, and the stirring shaft 10 drives the stirring rods 11 to rotate so as to realize the mixing and stirring of materials. And the filter screen 12 is above the stirring rods 11. After the materials enter the stirring tank 1, they first pass through the filter screen 12, and the filter screen 12 screens and filters the agglomerated or solidified materials.

[0026] The provision of the rib plate 7 improves the stability of the connection structure between the column 5 and the crossbar 6 .

[0027] The filter screen 12 is fixedly connected to a cone cylinder 13, the top of the cone cylinder 13 is fixedly connected to the outer wall of the filter screen 12, the bottom of the cone cylinder 13 is fixedly connected to a straight cylinder 14, the cone cylinder 13 and the straight cylinder 14 are coaxial with the filter screen 12, the cone cylinder 13 and the straight cylinder 14 are both arranged inside the mixing box 1, and there is a gap between the outer wall of the straight cylinder 14 and the inner wall of the mixing box 1, a support ring 16 is fixedly connected to the mixing shaft 10, a support rod 15 is fixedly connected to the outer wall of the support ring 16, one end of the support rod 15 away from the support ring 16 is fixedly connected to the inner wall of the straight cylinder 14, and a plurality of support rods 15 are provided, and the plurality of support rods 15 are evenly distributed around the circumference.

[0028] Since the filter screen 12 rotates with the stirring shaft 10, the agglomerated or solidified materials on the filter screen 12 will move toward the inner wall of the stirring box 1. After leaving the filter screen 12, the agglomerated or solidified materials fall into the cone cylinder 13 and pass through the cone cylinder 13 into the gap between the outer wall of the straight cylinder 14 and the inner wall of the stirring box 1. Since the cone cylinder 13 and the straight cylinder 14 also rotate with the stirring shaft 10, the agglomerated or solidified materials in the gap between the outer wall of the straight cylinder 14 and the inner wall of the stirring box 1 will be crushed and the crushed materials fall into the stirring box 1 for mixing and stirring.

[0029] The provision of the support ring 16 and the support rod 15 improves the structural strength of the conical cylinder 13 and the straight cylinder 14, and ensures the crushing effect of the straight cylinder 14 on the agglomerated or solidified materials.

The sliding plate 21 is slidably connected to the inside of the fixed cylinder 19. The spring 22 is connected between the sliding plate 21 and the top wall of the fixed cylinder 19. The rapping rod 20 is fixedly connected to the bottom surface of the sliding plate 21. The rapping rod 20 is slidably connected in the through hole 1901.

The top surface of the filter screen 12 is fixedly connected with a rapping block 17, and the rapping block 17 includes a thin block part 1701 and a thick block part 1702. The top surfaces of the thin block part 1701 and the thick block part 1702 form a step, and the outer side surface of the thick block part 1702 away from the thin block part 1701 is an arc surface 1703, and the arc surface 1703 faces the inclined surface 2001. The inclined surface 2001 and the fillet 2002 are slidably connected to the arc surface 1703. A plurality of rapping blocks 17 are fixedly connected to the top surface of the filter screen 12, and the plurality of rapping blocks 17 are evenly distributed around the circumference.

[0031] When the filter net 12 rotates, the vibration block 17 rotates along with the filter net 12. The arc surface 1703 contacts the inclined surface 2001 and the rounded corner 2002 to lift the vibration rod 20. At this time, the sliding plate 21 compresses the spring 22.

The setting of multiple vibration blocks 17 and multiple vibration components 8 improves the vibration effect.

[0032] The stirring rods 11 are provided with multiple layers, and the multiple layers of stirring rods 11 are linearly distributed evenly along the length direction of the stirring shaft 10.

[0035] The setting of the support seat is beneficial to the stable rotation of the stirring shaft 10. The setting of the support seat also needs to consider the use of bearings, bearing caps, circlips and dynamic seals. Since the use of bearings and related accessories are structures commonly used in this field, no detailed description will be given here. In addition, since the support seat is arranged inside the mixing tank 1, the use of dynamic seals for isolation from the building materials also needs to be considered for the bearings here.

[0036] On the side wall at the bottom of the mixing tank 1, a discharge pipe 2 is provided, and a valve is connected to the discharge pipe 2. The setting of the discharge pipe 2 is used for discharging the building materials after mixing and stirring.
