AI Technical Summary
The existing pre-storage hoppers of concrete mixers cannot adjust the feeding speed during the material feeding process, resulting in uneven mixing and low production efficiency, which affects concrete quality and production adaptability.
The system employs a servo motor-driven active and driven gear system. Through tooth meshing, the baffle plate is driven to adjust the feeding speed. Combined with a duct fan and filter system, dust is collected, thereby controlling the feeding speed and environmental pollution.
It enables flexible adjustment of the feeding speed, improves mixing uniformity and production efficiency, and reduces dust emissions, thus reducing environmental pollution.

Description
TECHNICAL FIELD

[0002] Concrete mixer pre-storage hopper, commonly known as aggregate buffer hopper or temporary storage hopper, is an important equipment set in concrete mixing station, and its main role is to temporarily store a batch of aggregate that has been accurately metered to ensure the continuity of concrete production. After the aggregate is batched by the batching machine according to the specified parameters, it will be temporarily stored in the aggregate buffer hopper and then sent to the mixing host for mixing. The aggregate buffer hopper is usually not located directly below the batching machine but above the mixing host. This design helps to optimize material flow and production process in the mixing station. In some large or continuous production concrete mixing stations, the aggregate buffer hopper is a standard equipment, which is of great significance to improve production efficiency and ensure product quality.
[0003] Although the prior art meets the user's use demand to some extent, there are still some defects in the use process, and the specific problems are as follows: the existing concrete mixer pre-storage hopper does not have the function of adjusting the feeding speed during discharging, and it is difficult to flexibly control the feeding rate of aggregate according to production needs, which may affect the uniformity of concrete mixing and production efficiency. Specifically, the lack of function to adjust the feeding speed will cause a large amount of aggregate to flow into the mixing host in a short time, which may cause uneven mixing and even cause the mixer to overload, thereby affecting the final quality of concrete and production rhythm. At the same time, the inability to adjust the feeding speed will also reduce the adaptability of the mixing station to production changes, limiting its flexibility and production efficiency.
