Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-4 As shown, the utility model provides a technical solution: a machine-made sand concrete mixing equipment, comprising a barrel body 1, four evenly distributed legs 6 are fixedly connected to the periphery of the barrel body 1, a feed hopper 2 is fixedly connected to the front side of the barrel body 1, and a water inlet pipe 5 is fixedly connected to the side of the barrel body 1, a discharge pipe 7 is fixedly connected to the bottom of the barrel body 1, and a valve is provided on the discharge pipe 7, a vertical rod 12 is provided in the barrel body 1, and a stirring rod 11 is provided on the periphery of the vertical rod 12, a motor 3 is provided on the top of the barrel body 1, the top of the vertical rod 12 extends to the outside of the barrel body 1 and is transmission-connected to the output end of the motor 3, a screen 8 is fixedly connected in the barrel body 1, the screen 8 is located above the water inlet pipe 5, the mesh surface of the screen 8 is inclined, and a discharge port is opened on the side wall of the barrel body 1.

[0023] According to the overall structure of the device, when in use, materials such as machine-made sand are poured into the feed hopper 2, and water is supplied to the barrel body 1 through the water inlet pipe 5. After the machine-made sand enters the barrel body 1, it falls on the screen 8, and the impurities in the machine-made sand are separated by the screen 8, and the machine-made sand is screened. Then, the motor 3 is turned on, and the motor 3 drives the vertical rod 12 to rotate, and drives the stirring rod 11 to rotate to stir and mix the material and water into concrete. After the stirring is completed, the valve is opened to discharge the concrete from the discharge port.

[0024] like Figure 3As shown, a vertical tube 13 is sleeved on the outside of the vertical rod 12, the vertical tube 13 is movably connected to the screen 8, and passes through the screen 8 and is movably connected to the barrel body 1, the vertical rod 12 and the vertical rod 12 are fixedly connected with stirring rods 11, the stirring rods 11 are provided with two groups distributed inside and outside, and each group of stirring rods 11 is provided with four, the bottom end of the vertical rod 12 and the outside of the vertical tube 13 near the bottom end are fixedly connected with a cross-shaped fixing plate 10, and the two groups of stirring rods 11 are respectively fixedly connected at the four ends of the two fixing plates 10.

[0025] The concrete is fully and completely mixed by a plurality of stirring rods 11 .

[0026] like Figure 3 As shown, the stirring rod 11 is composed of a fixed rod 1101 and a vertical plate 1102. The vertical plate 1102 is fixedly connected to the bottom end of the fixed rod 1101. The vertical rod 12 is fixedly connected to the fixed plate 10. The cross section of the vertical plate 1102 is a rhombus.

[0027] The fixing rod 1101 and the vertical tube 13 form the stirring rod 11, which increases the effective contact surface between the stirring rod 11 and the concrete and improves the stirring range of the concrete. The contact surface between the vertical plate 1102 with a diamond cross-section and the concrete is an inclined surface, which can reduce the resistance between the vertical plate 1102 and the concrete.

[0032] Working principle: When in use, the device is connected to an external power supply, and materials such as machine-made sand are poured into the feed hopper 2, and water is transported into the barrel body 1 through the water inlet pipe 5. After the machine-made sand enters the barrel body 1, it falls on the screen 8. The impurities in the machine-made sand are separated by the screen 8, and the machine-made sand is screened. Then the motor 3 is turned on, and the motor 3 drives the vertical rod 12 to rotate, and drives the stirring rod 11 to rotate to stir and mix the materials and water into concrete. The concrete is fully and completely stirred and mixed by multiple stirring rods 11, and the vertical rod 12 and the vertical pipe 13 are rotated in the opposite direction through the cooperation of the first bevel gear 14 and the second bevel gear 15, thereby driving the two groups of stirring rods 11 to rotate in the opposite direction, so that the inner and outer layers of concrete are evenly mixed. During the rotation of the vertical pipe 13, the cross bar 9 is driven to rotate, thereby sweeping the impurities on the screen 8 and the machine-made sand that cannot pass through the screen hole, and under the action of the inclined screen 8 mesh surface, the impurities and machine-made sand move to the discharge port, and discharge the barrel body 1 from the discharge port. After the mixing is completed, the valve is opened to discharge the concrete from the discharge port.
