Under the action of the fixed bevel gear 222, it rotates, thereby driving the mixing column 219 to rotate, so that the mixing column 219 can revolve together with the central rotating column 217 while also rotating relative to the central rotating column 217. The cement ash, water and sand and gravel are fully mixed by the mixing column 219, and then the raw material mixture on the upper mixing chamber 223 is pushed to the lower mixing chamber 225 through the upper drop port 224 by the stripping plate 218. Then, the raw material mixture is mixed by the mixing column 219 and the stripping plate 218 on the lower mixing chamber 225 and pushed to the outlet chamber 227 through the lower drop port 226. Then, the concrete is pushed out from the outlet 202 to the inlet pipe 307 through the stripping plate 218 on the outlet chamber 227.

[0040] The prepared concrete enters the temporary storage barrel 304 through the inlet pipe 307. The bottom motor 302 rotates to drive the cone wheel 303 to rotate, and the cone wheel 303 drives the temporary storage barrel 304 and the semicircular wheel 305 to rotate, so that the concrete will not solidify in the temporary storage barrel 304. When it is needed, the discharge drawer 306 is pulled out and the concrete flows out through the outflow hole 308.
[0041] The working principle of a continuous concrete preparation device disclosed in the present invention is as follows: the mixing motor 205 rotates to drive the motor gear 206 to rotate, thereby driving the intermediate gear 212 to rotate, the intermediate gear 212 drives the water supply gear 208, the mixing gear 216 and the docking gear 213 to rotate, the docking gear 213 drives the transmission gear 214 to rotate, the transmission gear 214 drives the column gear 106 to rotate, the water supply gear 208 rotates to drive the connecting rotating block 209 to rotate, and put sand and gravel into the upper feed hopper 102, and put cement ash into the lower feed hopper 103. In the initial state, the upper docking groove 115 and the lower docking groove 114 are not aligned, and the cement ash in the lower feed hopper 103 is piled on the conveyor belt 112 located below the lower feed hopper 103. When the column gear 106 rotates, it will drive the rotating column 105 and the eccentric rotating rod 107 to rotate. The rotation drives the screen frame 104 to slide in the mixing box 101, so that the lower docking groove 114 reaches below the upper docking groove 115, and the sand and gravel in the upper feed hopper 102 falls onto the screen frame 104 through the lower docking groove 114 and the upper docking groove 115, and the sand and gravel are shaken by the screen frame 104.

When the water inlet 210 moves to the bottom of the notch of the notch plate 211, the water in the water supply pipe 207 begins to enter the mixing drum 201, realizing the quantitative introduction of water. The mixing gear 216 rotates to drive the central rotating column 217 to rotate, thereby driving the mixing column 219 and the material-diverting plate 218 to rotate. When the mixing column 219 rotates together with the central rotating column 217, the rotating bevel gear 220 rotates under the action of the fixed bevel gear 222, thereby driving the mixing column 219 to rotate, thereby realizing that the mixing column 219 rotates together with the central rotating column 217 and also rotates relative to the central rotating column 2 17 rotates, and the cement ash, water and sand and gravel are fully mixed by the mixing column 219. Then, the raw material mixture on the upper mixing chamber 223 is pushed to the lower mixing chamber 225 through the upper drop port 224 by the material stripping plate 218. Then, the raw material mixture is mixed by the mixing column 219 and the material stripping plate 218 on the lower mixing chamber 225 and pushed to the outlet chamber 227 through the lower drop port 226. Then, the concrete is pushed out from the outlet 202 to the inlet pipe 307 by the material stripping plate 218 on the outlet chamber 227. The three-layer design in the mixing cylinder 201 can fully mix the cement ash, water and sand and gravel, and keep the concrete moving to prevent solidification.The prepared concrete enters the temporary storage barrel 304 through the inlet pipe 307. The bottom motor 302 rotates to drive the cone wheel 303 to rotate, and the cone wheel 303 drives the temporary storage barrel 304 and the semicircular wheel 305 to rotate, so that the concrete will not solidify in the temporary storage barrel 304. When it is needed, the discharge drawer 306 is pulled out and the concrete flows out through the outflow hole 308.
