[0002] The sand mixing device for a clay sand production line is usually used to mix and stir the raw materials of clay sand. Some sand mixing devices also have the function of crushing raw materials to improve production efficiency and product quality.

[0003] According to a sand mixing device for a clay sand production line (publication number: CN218080257U) announced, in the above application, by setting a motor, a stirring shaft, stirring blades, resistance reducing holes, a two-way pulley, a one-way pulley, a support shaft, a driving gear, an external gear disc and a mixing tank, this device can drive the mixing tank to rotate in the opposite direction to the stirring shaft direction through a two-way stirring mechanism, so that when the stirring shaft stirs the raw materials through the stirring blades, the mixing tank can rotate in the opposite direction at the same time, thus greatly improving the stirring efficiency of this device. In the casting industry, the clay sand production line is a commonly used production process line, and the sand mixing device is one of the key equipment in the clay sand production line. During the long-term use of the traditional clay sand mixing device, due to the viscosity of the clay sand and the friction and collision during the sand mixing process, the sand material is easy to adhere to the inner wall of the sand mixing device. As the production continues, the sand material adhered to the inner wall will accumulate continuously. This will not only reduce the effective volume of the sand mixing device, affect the uniformity and quality of sand mixing, but also may have an adverse impact on the subsequent casting production process due to problems such as caking and deterioration of the sand material.
