[0004] The advantage of high efficiency solves the problem that the current mixing equipment has poor mixing effect and uneven mixing between raw materials, thereby reducing production quality and work efficiency.

[0005] However, the above-mentioned raw material mixing equipment has the following disadvantages: the raw material mixing equipment controls the grinding roller to grind the silicon material and desulfurized gypsum through the second motor, and then controls the first rotating rod and the second rotating rod to mix and stir all the raw materials through the first motor to make the raw materials mixed evenly. However, the raw material mixing equipment requires two motors during production. Although the two motors can enable the raw material mixing equipment to produce better, they increase the mixing cost of the raw materials.

[0006] Therefore, it is necessary to provide a raw material mixing device for producing autoclaved aerated concrete panels to solve the above technical problems. Utility Model Content

[0007] The utility model aims to provide a raw material mixing device for producing autoclaved aerated concrete panels, which allows grinding and stirring to be performed simultaneously without using two motors, is simple to operate, and reduces the production cost.

[0008] The above technical purpose of the utility model is achieved through the following technical solutions: a raw material mixing device for the production of autoclaved aerated concrete panels, comprising a mixing box and a motor, a support frame is fixedly installed on the top side of the mixing box, a motor is fixedly installed on the support frame, an output end of the motor passes through the support frame and the top wall of the mixing box, a first rotating shaft is fixedly installed on the output end of the motor, a grinding frame is fixedly installed inside the mixing box, the bottom end of the first rotating shaft is located in the grinding frame, a grinding mechanism is provided at the bottom end of the first rotating shaft, a driving wheel is fixedly installed on the top of the first rotating shaft, A top plate is fixedly connected to the side of the mixing box, a connecting shaft is rotatably installed on the top plate, a driven wheel is fixedly installed on the top of the connecting shaft, the driving wheel and the driven wheel are connected by belt transmission, a main bevel gear is fixedly connected to the bottom end of the connecting shaft, a bottom plate is fixedly installed on the outside of the mixing box, the bottom plate is "L"-shaped, a second rotating shaft is rotatably installed on the bottom plate, a slave bevel gear is fixedly installed on one end of the second rotating shaft close to the main bevel gear, the main bevel gear is meshingly connected with the slave bevel gear, the second rotating shaft passes through the side wall of the mixing box, and a stirring mechanism is arranged on the second rotating shaft.

[0009] By adopting the above technical scheme, when in use, first add the silicon material and desulfurized gypsum into the grinding frame, and then add the sand, cement, lime and water with a good ratio into the mixing box. The grinding frame separates the two groups of materials, and the motor is started. The output end of the motor drives the first shaft to rotate. When the first shaft rotates, it drives the grinding mechanism to grind the silicon material and the desulfurized gypsum. At the same time, the first shaft drives the driving wheel to rotate. When the driving wheel rotates, it drives the driven wheel to rotate through the belt. The driven wheel then drives the main bevel gear to rotate through the connecting shaft. The main bevel gear drives the slave bevel gear to rotate through the meshing transmission. When the slave bevel gear rotates, it drives the second shaft to rotate. When the second shaft rotates, it drives the mixing mechanism to mix the sand, cement, lime and water. After the first shaft and the second shaft rotate for a period of time, the ground silicon material and desulfurized gypsum fall into the mixing box and are mixed with sand, cement, lime and water to mix all the raw materials evenly. The motor, the first shaft and the second shaft allow grinding and mixing to be carried out simultaneously without using two motors. The operation is simple and the production cost is reduced.

[0010] The utility model is further configured as follows: the grinding mechanism includes a grinding plate, the bottom end of the first rotating shaft is fixedly connected to the grinding plate, the bottom end of the grinding plate is fixedly installed with a plurality of grinding balls, the bottom end of the grinding frame is slidably connected to a rolling plate, the rolling plate passes through the mixing box, and a handle is fixedly installed on the end of the rolling plate away from the grinding frame.

[0011] By adopting the above technical solution, during grinding, the output end of the motor drives the first rotating shaft to rotate, and the first rotating shaft drives the grinding plate and multiple grinding balls to rotate together to grind the silicon material and desulfurized gypsum in the grinding frame. After the grinding is completed, the rolling plate is pulled out from the bottom of the grinding frame through the handle to let the ground silicon material and desulfurized gypsum fall.

[0012] The utility model is further configured as follows: the stirring mechanism comprises a fixed ring, a plurality of fixed rings are fixedly mounted on the second rotating shaft, and stirring blades are fixedly mounted on the plurality of fixed rings.

[0013] By adopting the above technical solution, during stirring, the second rotating shaft drives the multiple stirring blades to stir the raw materials through the multiple fixed rings.

[0014] The utility model is further configured as follows: a filter is fixedly installed at the bottom of the grinding frame, sliding rods are fixedly installed at both ends of the rolling plate, and sliding grooves are provided on the inner side relative to the bottom end of the grinding frame, and the sliding rods are adapted to the sliding grooves.

[0015] By adopting the above technical solution, the rolling plate is slidably connected to the grinding frame through the slide groove and the slide rod. After grinding for a period of time, the rolling plate is slid to allow the ground raw materials to be filtered by the filter and then fall down. The raw materials that cannot be filtered continue to be ground until they meet the grinding requirements.

[0016] The utility model is further configured as follows: a limiting groove is provided at one end of the bottom of the grinding frame, the limiting groove is connected to the slide groove, the height of the limiting groove is smaller than the height of the slide groove, a limiting plate is fixedly installed at one end of the rolling plate close to the grinding plate, and the height of the limiting plate is the same as the height of the slide groove.

[0017] By adopting the above technical scheme, since the height of the limit plate is the same as the height of the slide, and the height of the limit groove is smaller than the height of the slide, when the rolling plate is pulled out of the slide, the limit plate and the limit groove prevent the rolling plate from being completely separated from the slide, which makes it convenient for the operator to reset the rolling plate after the silicon material and desulfurization gypsum fall, allowing the grinding balls to continue the subsequent grinding.

[0018] The utility model is further configured as follows: a first feed inlet is fixedly installed on the top of the mixing box, and a second feed inlet is fixedly installed on the outer side of the mixing box.

[0019] By adopting the above technical solution, during stirring, silicon material and desulfurized gypsum are added into the grinding frame through the first feed port, and then sand, cement, lime and water are added into the mixing box through the second feed port.

[0020] To sum up, the utility model has the following beneficial effects: the utility model drives the first rotating shaft to rotate through a motor, and when the first rotating shaft rotates, it drives the grinding plate and the grinding balls to grind the silicon material and the desulfurized gypsum. At the same time, the first rotating shaft drives the driven wheel to rotate through the driving wheel and the belt, and when the driven wheel rotates, it drives the slave bevel gear to rotate through the connecting shaft and the main bevel gear, and when the slave bevel gear rotates, it drives the mixing blades on multiple fixed rings through the second rotating shaft to mix sand, cement, lime and water, etc., so as to achieve the effect that one motor can perform grinding and mixing at the same time, without using two motors, simple operation, and reduced production costs.
