[0031] Working principle: The utility model is a concrete feeding trolley. During use, the mixed concrete is poured into the mixing barrel 5, and then the bottom plate 1 is pushed by the grip 4. The bottom plate 1 drives the universal wheel 2 to roll on the ground to move the device to a suitable position. At this time, the right end of the discharge pipe 7 is aligned with the concrete pouring position, and then the motor 12 is started. The motor 12 drives the screw 9 and the first groove wheel 11 to rotate. The first groove wheel 11 drives the second groove wheel 24 to rotate through the belt 32. The second groove wheel 24 drives the eccentric wheel 20 and the second bevel gear 19 to rotate through the rotating rod 23. The second bevel gear 19 drives the square tube 15 to rotate through the first bevel gear 18. The square tube 15 rotates in the inner cavity of the second bearing 14. The square tube 15 drives the square rod 16 to rotate. The square rod 16 drives the movable plate 25 and the stirring blade 17 to rotate. The movable plate 25 rotates at the bottom end of the limit rod 29 under the action of the fourth bearing 27. The stirring blade 17 rotates to stir the concrete to prevent the concrete from solidifying.

[0032] When the raised portion of the eccentric wheel 20 rotates and touches the wear-resistant pad 26, the movable plate 25 moves upward. The movable plate 25 moves upward, and the movable plate 25 drives the limit rod 29 to move in the inner cavity of the perforation 28. At the same time, the spring 30 is compressed, and the movable plate 25 drives the square rod 16 to move in the inner cavity of the square tube 15. The square rod 16 drives the stirring blade 17 to move upward. When the raised portion of the eccentric wheel 20 rotates away from the wear-resistant pad 26, the movable plate 25 moves downward under the action of the spring 30, and the movable plate 25 drives the square rod 16 to drive the stirring blade 17 to move downward, that is, when the motor 12 drives the stirring blade 17 to rotate, it can also drive the stirring blade 17 to move up and down, so that different layers of concrete can be stirred, the mixing effect is better, and adhesion is avoided;

[0033] The concrete passes through the discharge pipe 8 and enters the discharge pipe 7. When the screw 9 rotates, the concrete is discharged to the pouring position.

[0034] Compared with the prior art, the device uses a motor 12 to stir different layers of concrete, achieve better mixing effect and avoid adhesion, and can also drive the screw 9 to rotate for discharging, which greatly saves energy and promotes environmental protection.
