Description

Technical Field

[0001] The utility model relates to the field of mixing devices, in particular to a small concrete mixing and stirring device. Background Art

[0002] Today's concrete mixers are all large-scale engineering machinery that require the use of professional loading vehicles for overall transportation. When the construction site is located in an inconvenient area or the amount of concrete required for construction is small, it is not easy to relocate the large concrete mixer to the construction site. Concrete can only be processed manually, which is labor-intensive and inefficient, thus affecting the construction progress.

[0003] According to patent publication number CN105773836A, a new type of small concrete mixer is provided, which includes a moving wheel, a bracket, a cylinder body, a nozzle, a stirring rod, a rotating shaft, a push handle, a discharge port, a balancing leg, a motor, a motor base and a wheel axle. The moving wheel is fixed to the lower part of the bracket through the wheel axle; the cylinder body is arranged on the upper part of the bracket; the nozzle is fixed to the left and right edges of the cylinder body through claws; the stirring rod is fixed on the rotating shaft; the push handle is welded to the right side of the bracket; the discharge port is arranged on the front side of the cylinder body; the balancing leg is connected to the lower part of the cylinder body through a folding shaft; the motor is arranged at the lower part of the cylinder body; and the motor base is arranged at the lower part of the motor. The arrangement of the nozzle, balancing leg and moving wheel of the present invention improves the mixing quality, extends the service life of the equipment, is convenient to move, saves manpower, is simple to operate, improves efficiency, and is easy to promote and use.

[0004] There are still some deficiencies in the patent application. The small concrete mixer in the patent adopts a flat mixing blade, which has only a pushing effect on the mixed materials but no tumbling effect, resulting in poor mixing effect. Therefore, a small concrete mixing device is needed to solve this problem. Utility Model Content

The spiral rotation can make the concrete raw materials continuously turn over and mix, and the mixing effect is good. At the same time, it can be driven to move to the lower material block 5. When After the concrete moves to one end of the mixing drum 2, if the electromagnetic door 51 of the discharge block 5 is in the closed state, the concrete will accumulate. At this time, the rotating motor 61 is started to drive the rotating shaft 62 to rotate, and the rotating shaft 62 drives the gear 63 to rotate. The gear 63 uses the pushing serrations 551 engaged with it to drive the pushing rod 55 to enter the pushing trough 21 to push the accumulated concrete back to the bottom of the feed pipe 22 for cyclic mixing until the concrete is completely mixed. The electromagnetic door 51 is opened, and the concrete enters the discharge trough 52 and finally falls from the discharge pipe 53 for collection. This design greatly improves the mixing efficiency and is highly practical.
