Two bevel gears 28, the rotating rod 23 is provided with the second gear 22 away from the end of the moving rod, and the inner side walls of the two third fixed rods 26 away from the first support plate 3 are fixedly connected with the sliding track 7, and the sliding track 7 is provided with a sliding track 7. Block 8, a movable rod 6 is arranged between the moving block 8 and the rotating disk 5, and the movable rod 6 is respectively connected in rotation with the rotating disk 5 and the moving block 8 through the second rotating shaft and the third rotating shaft, each second One end of the fixed rod 18 away from the first support plate 3 is fixedly connected with a third support plate 20, the upper surface of the third support plate 20 is provided with two second support plates 19 arranged in parallel, and the top of the third support plate 20 is provided with a third support plate 20. There is a stirring box 14, the outer wall of the stirring box 14 is provided with an annular plate 12 matched with the second support plate 19, and the side of the stirring box 14 near the third fixed rod 26 is provided with a first gear 22 matched with the second gear. The gear 11 can make the concrete mix evenly and thoroughly through the left and right reciprocating movement of the stirring rod 10 and the rotation in the opposite direction of the self-propagation and the mixing box 14.
 Stirring box 14 is provided with inlet and outlet 15 on one side away from the third fixed rod 26, is positioned at the upper surface of the first support plate 3 between the second fixed rods 18 and is provided with push rod motor 21, and the inside of moving block 8 is provided with First rotating motor 9, the output end of the first rotating motor 9 is provided with stirring rod 10, and stirring rod 10 runs through the inner sidewall of moving block 8, the third fixed rod 26 and stirring box 14 and extends to the inside of stirring box 14, stirring The shaft of the rod 10 is provided with a plurality of symmetrical stirring rods 13, and the upper surface of the first support plate 3 located below the inlet and outlet 15 is provided with a buffer device 17, and the end of the buffer device 17 away from the first support plate 3 is fixedly connected together. There is a buffer plate 16, which plays a buffering role when the material is poured. The buffer device 17 is composed of an elastic rod and a spring wound on the elastic rod. The inner surface of the second support plate 19 is provided with evenly distributed balls, which is beneficial to the stirring box 14. Rotate, the side wall of the third fixed rod 26 between the second rotating motor 25 and the rotating disc 5 is provided with a movable groove matched with the movable rod 6, and the mixing box 14 is close to the side wall of the third fixed rod 26 A circular groove is provided, and the first rotating motor 9, the second rotating motor 25 and the push rod motor 21 are all electrically connected with an external power supply through wires.
 In the present invention, when stirring operation is required, the stirring raw materials are transported into the stirring box 14, and the second rotating motor 25 drives the rotating disk 5 to rotate through the belt, and then the movable rod 6 is moved, and the movable rod 6 drives the moving block 8 Moving back and forth on the sliding track 7, the first rotating motor 9 inside the moving block 8 drives the stirring rod 10 and the stirring rod 13 to rotate in a circle, and the second rotating motor 25 passes through the first bevel gear 27 and the second bevel gear 28. The function makes the rotating rod 23 rotate, drives the second gear 22 to rotate, the second gear 22 drives the first gear 11 to rotate, and then the stirring box 14 rotates, and the left and right circular rotation of the stirring rod 10 and the stirring rod 13, the stirring box 14 Rotate in the opposite direction, the concrete is fully mixed. After the mixing is completed, the push rod motor 21 tilts the mixing box 14, and pours the mixed concrete from the inlet and outlet 15. The buffer plate 16 and the buffer device 15 can buffer the mixing box 14. , the second support plate 19 supports the stirring box 14 and the balls on the inner surface of the second support plate 19 facilitate the rotation of the stirring box 14 .
