Detailed Description

Example 1

A concrete mixing and stirring system comprises a premixing mechanism and a three-dimensional stirring tank 6, wherein the premixing mechanism comprises a sand tank 1, a pebble tank 2 and a cement tank 3; the sand tank 1, the stone tank 2 and the cement tank 3 are respectively provided with a weighing conveyor belt 4 below, the weighing conveyor belt 5 is arranged below the weighing conveyor belt 4, the tail end of the mixing conveyor belt 5 is provided with a three-dimensional stirring tank 6, a feeding port 61 matched with the mixing conveyor belt 5 is formed in the top of the three-dimensional stirring tank 6, the three-dimensional stirring tank 6 is internally connected with a main rotating shaft 62, the main rotating shaft 62 is connected with a sun gear 63, the sun gear 63 is connected with a rotating device 64, an inner gear ring 65 is arranged on the periphery of the sun gear 63, a plurality of planetary gears 66 are meshed between the sun gear 63 and the inner gear ring 65, the planetary gears 66 are connected with an auxiliary rotating shaft 67, the main rotating shaft 62 and the auxiliary rotating shaft 67 are both provided with stirring blades 68, the bottom.

The lower part of the three-dimensional stirring tank 6 is provided with a conical part 7, the conical part 7 is fixedly connected with a rubber backing ring 71, the rubber backing ring 71 is inserted into a fixedly connected fixing ring 72, a support 8 is arranged below the fixing ring 72, an annular groove 73 matched with the fixing ring 72 is formed in the support 8, and the bottom of the annular groove 73 is connected with the bottom of the fixing ring 72 through a spring 74.

The agitating blades 68 of the main rotating shaft 62 and the agitating blades 68 of the sub rotating shaft 67 are disposed alternately with each other. The rotating device 64 is a motor. The feed inlet 61 is conical
