Technical Field

[0001] The utility model relates to the technical field of batching machines, in particular to a concrete batching machine. Background Art

[0002] Concrete is made by mixing raw materials such as aggregate, cement, water, admixtures and additives in a certain proportion. It is one of the most widely used materials in construction projects. Concrete mixing plants have become the main place for concrete production. When mixing concrete in concrete mixing plants, batching machines are needed to batch the concrete.

[0005] 1. The feed port of the existing concrete batching machine is mostly located above the hopper, which is relatively high. When loading, the sand and gravel to be batched need to be lifted to the top of the hopper for loading. This also makes the loading process of the batching machine more cumbersome, time-consuming and labor-intensive, reduces the efficiency of batching, and increases the labor intensity of the staff;

[0006] 2. The existing concrete batching machine does not have the screening function, which also results in the batching machine being unable to separate the large pieces of gravel and pebbles in the sand and gravel during use, resulting in poor quality of the produced concrete, affecting the use of concrete, reducing the practicality of the batching machine, and making it inconvenient to promote.

When sand and gravel fall from the inside of the hopper into the installation groove, the vibration generated by the high-frequency vibration device is first started, so that the sand and gravel falling on the filter screen will be shaken, and the sand and gravel that meet the size will fall directly onto the conveyor belt, while the large pieces of gravel and pebbles in the sand and gravel will be blocked by the filter screen for subsequent cleaning. At the same time, during the up and down shaking of the screening frame, the elastic force of the spring is used to weaken and slow down the impact force of the screening frame falling, preventing the impact force from being too large and causing damage to the filter screen, thereby increasing the service life of the filter screen. This design enables the batching machine to have a screening function, avoids the problem that the batching machine cannot separate large pieces of gravel and pebbles in the sand and gravel during use, improves the practicality of the batching machine, and facilitates promotion.
