[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1: Please refer to Figure 1-Figure 3 , the utility model provides a technical solution:

[0021] A mixer for producing foamed concrete comprises a mixing tank 1, wherein a driven gear 2 is provided at the center above the mixing tank 1, a rotary joint 3 is provided at the center above the driven gear 2, a foam conduit 4 is connected inside the rotary joint 3, one side of the driven gear 2 is meshed with a transmission gear 1 5, the top of the transmission gear 1 5 is connected to the output end of a first motor 6, a metal conduit 7 is provided at the bottom of the driven gear 2, a plurality of stirring blades 8 are connected to the outside of the metal conduit 7, a material guide pipe 9 is connected below the stirring blades 8, a gear ring 10 is provided at the bottom outside the mixing tank 1, one end of the gear ring 10 is meshed with a transmission gear 2 11, and the bottom of the transmission gear 2 11 is connected to the output end of a second motor 12.

[0022] Specifically, the metal conduit 7 passes through the interior of the driven gear 2 and is connected to the rotary joint 3. The metal conduit 7 is communicated with the foam conduit 4 through the rotary joint 3. The metal conduit 7 is communicated with the material guide pipe 9. Both the metal conduit 7 and the material guide pipe 9 are provided with a plurality of discharge holes 13. The rotary joint 3 can connect the foam conduit 4 with the metal conduit 7, so that the foam in the foam conduit can be introduced into the metal conduit 7, so that the foam can be directly guided to be mixed in the concrete.

[0023] Specifically, a support seat 14 is provided under the mixing tank 1, and a plurality of support legs 15 are provided at the bottom of the support seat 14. The mixing tank 1 is rotatably connected inside the support seat 14. The rotation direction of the mixing tank 1 is opposite to the rotation direction of the metal conduit 7 and the stirring blade 8. A discharge pipe 16 is provided at the bottom of the mixing tank 1, and a solenoid valve 17 is provided on the discharge pipe 16. The mixing tank 1 can rotate inside the support seat 14, thereby driving the concrete in the mixing tank 1 to rotate, and then cooperating with the stirring blade 8 to increase the stirring and mixing speed of the concrete and foam.

[0024] Example 2: Please refer to Figure 2 , Figure 3 The difference between this embodiment and embodiment 1 is that a plurality of balls 18 are provided at the bottom of the mixing tank 1, and the balls 18 are distributed in a circular ring shape at the bottom of the mixing tank 1.

The balls 18 can be connected between the mixing tank 1 and the support seat 14 to reduce the friction between the mixing tank 1 and the support seat 14, thereby reducing the resistance of the mixing tank 1 when rotating inside the support seat 14.

[0025] The working principle of the utility model is as follows: when in use, concrete is first introduced into the mixing tank 1, and then the foam conduit 4 is connected and the first motor 6 and the second motor 12 are started. When the first motor 6 is running, it can drive the transmission gear 1 5, the driven gear 2 and the metal conduit 7 to rotate, thereby driving the stirring blade 8 to rotate and stir. When the stirring blade 8 rotates, the concrete can be stirred. When the second motor 12 is running, it can drive the transmission gear 2 11 and the gear ring 10 to rotate, thereby driving the mixing tank 1 to rotate in the opposite direction of the stirring blade 8, so that the stirring blade 8 can quickly stir the concrete. When stirring the concrete, the foam can be guided into the concrete through the metal conduit 7 and the guide pipe 9, so that the foam can be directly guided to stir inside the concrete, thereby increasing the mixing speed of the foam and the concrete, and making the foam and the concrete mixed more evenly.
