[0002] Concrete is a building material widely used in construction and engineering, mainly composed of water, sand, stone and cement. It is widely used in modern construction due to its high strength, strong durability, and easy molding. Usually, cement is used as a cementitious material, sand and stone are used as aggregates, and water is mixed in a certain proportion to obtain cement concrete. Under the demand for a large amount of concrete, the supply of concrete prepared by manual mixing is obviously insufficient, and after the preparation of the concrete, once it is left for more than a period of time, it will solidify, affecting its use; the concrete preparation device in the prior art is usually unable to automatically control the feed ratio of the concrete raw materials, and at the same time, it is unable to achieve continuous automatic preparation, and the concrete may solidify during the preparation process.

[0006] The sand and gravel are put into the upper feed hopper, and the cement ash is put into the lower feed hopper. In the initial state, the upper docking groove and the lower docking groove are not aligned, and the cement ash in the lower feed hopper is piled on the conveyor belt located below the lower feed hopper. When the column gear rotates, it will drive the rotating column and the eccentric rotating rod to rotate. The rotation of the eccentric rotating rod drives the screen frame to slide in the mixing box, so that the lower docking groove reaches below the upper docking groove, and the sand and gravel in the upper feed hopper falls onto the screen frame through the lower docking groove and the upper docking groove, and the sand and gravel are shaken by the screen frame. The sand and gravel that meet the size requirements fall into the mixing box through the holes of the screen frame, and the sand and gravel that do not meet the size requirements eventually slide out from the end of the screen frame, and the sand and gravel fall from the mixing box onto the toggle wheel, and finally fall into the mixing drum. The rotation of the toggle wheel will drive the passive gear and the transmission wheel to rotate through the active gear, thereby driving the conveyor belt to move, and the cement ash located below the lower feed hopper is sent to the mixing drum through the conveyor belt to ensure the ratio of cement ash and sand and gravel.

[0012] Sand, gravel and cement enter the mixing barrel through the feed port in proportion. The rotation of the mixing motor drives the motor gear to rotate, thereby driving the intermediate gear to rotate. The intermediate gear drives the water supply gear, the mixing gear and the docking gear to rotate. The docking gear drives the transmission gear to rotate. The transmission gear drives the column gear to rotate. The rotation of the water supply gear drives the connecting rotating block to rotate. When the water inlet moves to the bottom of the notch of the notch plate, the water in the water supply pipe begins to enter the mixing barrel to achieve quantitative water entry.

When the mixing column rotates with the central rotating column, the rotating bevel gear acts on the fixed bevel gear. The mixing column rotates downward, thereby driving the mixing column to rotate, so that the mixing column revolves with the central rotating column and rotates relative to the central rotating column at the same time. The cement ash, water and sand and gravel are fully mixed by the mixing column, and then the raw material mixture on the upper mixing chamber is pushed to the lower mixing chamber through the upper drop port by the material stripping plate, and then the raw material mixture is mixed by the mixing column and the material stripping plate on the lower mixing chamber and pushed to the outlet chamber through the lower drop port, and then the concrete is pushed out from the outlet into the inlet pipe through the material stripping plate on the outlet chamber.
