Technical Field
[0001] The utility model relates to the technical field of concrete batching, in particular to a concrete batching weighing mechanism. Background Art
[0002] Concrete is a building material typically composed of a binder, aggregate, and water mixed in specific proportions. The most common form of concrete is an artificial stone formed by mixing cement as the binder with aggregates such as sand and gravel. Concrete is widely used in civil engineering due to its high strength and durability, capable of withstanding heavy loads and long-term use. During concrete processing, the ingredients must be carefully proportioned and weighed to enhance their strength and meet specific technical requirements.
[0003] The existing patent CN221350258U discloses a concrete batching weighing mechanism, including a batching hopper and a general mechanism. The general mechanism includes a pressure column, a fixed column, a support frame, a U-shaped groove, a baffle, a weighing sensor, a guide ring, a T-shaped stop pin, a controller and a side mounting plate. A bracket is installed outside the batching hopper box, and a general mechanism is arranged outside the bracket of the concrete batching machine's own batching hopper, so that the batching hopper is assembled into a concrete batching weighing mechanism with the help of the bracket and the general mechanism. The total weight of the concrete ingredients loaded into the batching hopper can be displayed on the controller of the general mechanism, and the concrete ingredients discharged from the weighing hopper, resulting in a reduction in the total weight of the materials at the batching hopper and the weighing hopper, can also be displayed on the controller. Workers can check the weight of the concrete ingredients discharged from the weighing hopper and the reduction in the total weight of the materials at the batching hopper and the weighing hopper on the controller, which is convenient for judging whether the weighing at the weighing hopper is normal.

When the ingredients are output, it is easy to output excess ingredients, which will affect the batching weighing effect. Moreover, when unloading, the outside of the weighing device lacks a protective structure, and the ingredients are easy to fall from the weighing device, which reduces practicality.
