Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, in particular to a raw material dropping mechanism for a concrete mixing station. Background Art

[0002] Concrete raw material stacker is a kind of mechanical equipment specially used for stacking and managing raw materials on concrete production lines. It can stack different kinds of concrete raw materials, such as aggregates, powders, etc., in designated silos or cargo yards according to preset formulas and stacking requirements to ensure the smooth progress of concrete production.

[0003] Generally, when stacking concrete aggregates, a movable conveyor is used to transfer the aggregates transported from the outside from the conveying vehicle to the cargo yard for stacking. For example, the Chinese utility model patent disclosed by publication number CN215973504U is a sand and gravel conveyor with a protective structure. The application protects the sand and gravel during the conveying process through the setting of the protective structure to prevent them from falling easily from both sides, and at the same time, it has a certain limiting effect on the position of the sand and gravel on the conveyor belt to prevent them from falling backwards due to their own gravity, resulting in poor conveying effect. At the same time, the application also sets a material guide structure to limit and guide the sand and gravel that fall on the conveyor belt, and at the same time has a certain blocking effect on it, thereby controlling the position of the sand and gravel on the conveyor belt. The invention relates to a material guide structure in which the gravel is transported to a cargo yard through a conveyor and is prevented from falling from both sides. The material guide structure in the invention is not significantly different from the unloading structure of the existing conveyor. That is, when the gravel is piled into the cargo yard through the conveyor, the gravel itself is relatively loose and there are gaps between the particles. When the inclined conveyor unloads the gravel, the friction and collision between the gravel will cause some fine particles to detach and form dust. At the same time, some impurities carried by the gravel itself will also cause the impurities to splash and form dust due to mutual collision during unloading. The dust floating in the air will reduce the visibility in the workplace, affect the operator's line of sight, increase the difficulty of operation and safety risks. On the other hand, long-term inhalation of dust may cause damage to the operator's respiratory system and induce respiratory diseases. Utility Model Content

Through the arrangement of the guide pipe 12, the water outlet pipe 16 and the atomizing nozzle 17, dust can be suppressed by atomizing spray when the conveyor 2 is unloading.

[0021] like Figure 2 As shown, the protective cover 18 is in an inverted trapezoidal structure, and the inner side of the protective cover 18 is inclined thirty degrees toward the center position.
