Description

Technical Field

[0002] Concrete is one of the main construction materials in current building projects. It is formed by using cement as a gelling material, sand and stone as aggregates, and mixing with water in a certain proportion. When the existing vertical concrete mixing tank is mixing, due to its certain height, the mixing efficiency of the concrete at the bottom and the upper layer is relatively low. And since cement is a gelling material, its density and viscosity are relatively high, so the discharging through the discharging pipe at the bottom is slow, and some concrete residues are easily adhered to the inner wall of the mixing tank and the mixing roller and solidify. The mixing roller is arranged inside the tank, and it is difficult to clean thoroughly. Content of the Utility Model

[0015] The present invention will be further described below with reference to the drawings:

[0016] As Figure 1 - Figure 2 shown, a concrete mixing device is composed of a stirring chamber barrel 1, a lifting and cleaning cylinder 2 and a stirring cover body 3;

[0017] The stirring cover body 3 is buckled on the top of the stirring chamber barrel 1, the lifting and cleaning cylinder 2 is installed on the side of the stirring chamber barrel 1, cover ears 4 are fixedly installed on both sides of the stirring chamber barrel 1, the end of the telescopic rod of the lifting and cleaning cylinder 2 is connected to the cover ear 4, and the lifting and cleaning cylinder 2 adopts an electric cylinder, and the stirring cover body 3 is lifted through its telescopic movement to facilitate the cleaning of internal parts;

[0018] A discharge hole is provided on the bottom barrel wall of the stirring chamber barrel 1, a feeding cylinder 5 is fixedly installed at the bottom of the discharge hole, and a bottom valve 6 of the cylinder is installed at the bottom end of the feeding cylinder 5;

[0019] At the center of the stirring cover 3, a rotating shaft 15 is rotatably installed through a bearing. At the bottom of the stirring cavity of the stirring cavity barrel 1, a turning barrel 20 is supported and installed through a support column 19. The bottom end of the rotating shaft 15 extends into the blanking barrel 5 through the turning barrel 20. On the rotating shaft 15 above the blanking barrel 5, a side roller column 16 is installed through a cross-column frame 14. A side stirring roller 17 is installed on the side roller column 16 for stirring the concrete material. An upper feeding auger 18 is installed on the rotating shaft 15 in the turning barrel 20. The upper feeding auger 18 is used to lift the concrete at the bottom of the stirring cavity barrel 1 to improve the stirring efficiency. A blanking auger 21 is installed on the rotating shaft 15 in the blanking barrel 5. When discharging is required, the rotating shaft 15 flips, and the blanking auger 21 quickly discharges the concrete;

[0020] A motor 13 is supported and installed on the stirring cover 3. A motor bevel gear 12 is installed on the motor shaft of the motor 13. The top end of the rotating shaft 15 extends above the stirring cover 3 and is fixedly installed with a shaft bevel gear 11. The shaft bevel gear 11 is meshed and connected with the motor bevel gear 12. The motor 13 is a positive and reverse drive motor, which can rotate forward for stirring and reverse for discharging.
