[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0023] Reference Figure 1-5 As shown, a pouring mixer for producing autoclaved aerated concrete blocks comprises a pouring mixer body 1, a lower hopper 3 arranged above the pouring mixer body 1, and a material passing pipe 2 connected and fixed between the lower hopper 3 and the pouring mixer body 1, and also comprises a pre-treatment mechanism for improving the material production quality of the pouring mixer body 1;

[0024] The pre-treatment mechanism includes a screen plate 4 for intercepting agglomerated materials and a crushing component for crushing agglomerated materials, and the screen plate 4 is fixed inside the lower hopper 3;

[0025] By setting the sieve plate 4 and the rolling component, when the material is added from the lower hopper 3 to the inner side of the pouring mixer body 1, the sieve plate 4 can effectively filter and intercept the agglomerated part of the added material to prevent the agglomerated material from directly entering the pouring mixer body 1 and affecting the mixing effect of the aerated concrete. In addition, the rolling component can still perform the rolling operation on the sieve plate 4 in real time, so that the agglomerated material can be further crushed and fall into the inner side of the pouring mixer body 1 for utilization, thereby increasing the utilization rate of the material and improving the use effect.

[0026] Further, refer to Figure 2 and Figure 4 As shown, it is worth noting that the rolling component includes a driving seat 5 with a cavity inside and arranged below the sieve plate 4, and a rotating rod 6 vertically rotatably arranged on the inner wall of the bottom end of the driving seat 5, the end of the rotating rod 6 rotates through the driving seat 5 and the sieve plate 4 in turn, and a bearing rod 7 is vertically rotatably arranged on the rod body of the rotating rod 6 located above the sieve plate 4, and a pressing roller 8 is tightly sleeved on the rod body of the bearing rod 7, and the driving seat 5 is fixedly connected to the inner wall of the lower hopper 3 through a bracket;

[0027] A circular ring-shaped movable groove 9 is provided on the inner wall of the lower hopper 3, a bevel gear plate 10 is fixed on the inner wall at the top of the movable groove 9, the end of the bearing rod 7 penetrates into the movable groove 9 and is fixed with a transmission bevel gear 11, and the transmission bevel gear 11 is meshed with the bevel gear plate 10;

[0028] By controlling the rotation of the rotating rod 6, the rotating rod 6 can be carried by the bearing rod 7 to rotate the pressure roller 8 above the screen plate 4 in the circumferential direction during the rotation process, and the transmission bevel gear 11 is meshed with the bevel gear plate 10 inside the movable groove 9 in real time, so that the pressure roller 8 rotates while rotating, and can crush the agglomerated materials on the screen plate 4 in all directions.

[0029] Further, refer to Figure 2 As shown, it is worth noting that a motor 12 is mounted on the outer wall of the lower hopper 3 through a bracket, a transmission rod 13 fixedly connected to the rotating rod 6 is rotatably penetrated through the bottom of the driving seat 5, and a transmission belt 14 is connected between the output shaft of the motor 12 and the rod body of the transmission rod 13, and the transmission belt 14 is inserted into the inner wall of the lower hopper 3;

[0030] When the motor 12 is turned on, the output shaft of the motor 12 can drive the transmission rod 13 via the transmission belt 14 , thereby providing continuous rotation force for the rotating rod 6 .

[0031] In addition, refer to Figure 2 and Figure 3 As shown, it is worth noting that the pre-treatment mechanism also includes a shock component for preventing the material from accumulating on the screen plate 4. The shock component is divided into two groups, and the two groups of shock components are respectively arranged on both sides of the rotating rod 6;

[0032] By setting the shock component, the bottom surface of the sieve plate 4 can be intermittently impacted from bottom to top during the process of the crushing component crushing the agglomerated material, thereby forming a vibration effect on the sieve plate 4. Then, by utilizing the vibration force, the material can be quickly dropped from the filter holes of the sieve plate 4, thereby reducing the residue of the material on the sieve plate 4 to avoid affecting the utilization rate of the material.

[0033] Further, refer to Figure 3 and Figure 5As shown, it is worth noting that the shock component includes a punching rod 22 vertically arranged beside the rotating rod 6, one end of the punching rod 22 vertically passes through the driving seat 5 upward, and an intermittent extrusion component is arranged below the other end of the punching rod 22. The punching rod 22 is located on the rod body inside the driving seat 5 and is tightly sleeved with a pressing sheet 20. Two spring telescopic rods 21 are symmetrically fixed between the pressing sheet 20 and the inner wall of the bottom end of the driving seat 5, and the punching rod 22 is located between the two spring telescopic rods 21;

[0034] The intermittent extrusion assembly includes a power rod 15 vertically rotatably arranged on the inner side wall of the driving seat 5 and a cam 17 tightly sleeved on the rod body of the power rod 15. The other end of the punching rod 22 is provided with a force groove 16 adapted to the cam 17, and the outer periphery of the cam 17 abuts against the inner wall of the top end of the force groove 16.

[0035] A driven bevel gear 18 is tightly sleeved on the end of the power rod 15, and a driving bevel gear 19 meshing with the driven bevel gear 18 is tightly sleeved on the body of the rotating rod 6;

[0036] When the rotating rod 6 rotates, the active bevel gear 19 can continuously mesh with the driven bevel gear 18, so as to rotate the power rod 15 and the cam 17 as a whole, causing the cam 17 to intermittently squeeze the inner wall of the top end of the force groove 16. During this period, when the cam 17 squeezes the inner wall of the top end of the force groove 16, the punching rod 22 is squeezed and rises to impact the bottom surface of the sieve plate 4. During this process, the pressing sheet 20 slides up synchronously with the punching rod 22 and compresses the spring telescopic rod 21. In this way, when the cam 17 rotates to no longer squeeze the inner wall of the top end of the force groove 16, the pressing sheet 20 can carry the punching rod 22 to quickly reset under the elastic force of the spring telescopic rod 21, which is convenient for secondary use.

[0037] Further, refer to Figure 3 As shown, it is worth noting that the top of the driving seat 5 is in the shape of a sloping roof;

[0038] By arranging the top of the driving seat 5 in a sloping roof shape, the accumulation of materials on the top of the driving seat 5 can be reduced to a certain extent, thereby improving the utilization rate of the materials.
