Description

Technical Field

[0001] The utility model relates to the technical field of concrete equipment, in particular to a concrete feeding device. Background Art

[0002] Concrete, also known as "concrete," is a general term for engineering composite materials composed of aggregates bonded together by a cementitious material. Concrete, commonly referred to as cement as the binder, sand and stone as aggregates, is mixed with water in a specific proportion and then mixed. It is widely used in civil engineering.

[0003] Publication number: CN 216658443 U proposes a concrete feeding device. In this case, a discharge port is provided at the bottom of the box body, and a discharge mechanism is threadedly connected to the discharge port. A discharge motor in the discharge mechanism drives a second rotating shaft to rotate, so that the rotating blades bring out the concrete, thereby promoting the discharge of concrete. The utility model has high discharge efficiency and will not cause discharge blockage. Therefore, the utility model can be widely applied to the field of concrete equipment. However, this case still has some defects in actual application. The discharge rate of concrete cannot be controlled. When concrete is injected into the formwork, a rate that is too fast may easily cause excessive filling of concrete, and a rate that is too slow may affect work efficiency. Therefore, it is necessary to propose a concrete feeding device to solve the above problems. Utility Model Content

[0026] 1. The utility model drives the worms on both sides to rotate through a dual-axis motor, and drives the worm wheels to rotate through engagement, so that the driven rod rotates and drives the rotating frame and the baffle to rotate as a whole, thereby changing the blocking range of the lower end of the discharge port and adjusting the discharge rate of concrete, which can better meet construction needs. When the two baffles at the bottom block the discharge port, the extension and contraction of the spring pushes the moving blocks on both sides to increase the distance, and the limit rod is inserted into the limit block, thereby fixing the two baffles and stably blocking them.
