Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete preparation, specifically a three-gate sand and gravel batching bin that can quickly and accurately dispense materials. Background Technology
[0002] In the concrete production and processing process, the batching machine is one of the core equipment of the mixing plant. Its ability to efficiently and accurately measure and batch sand and gravel aggregates directly determines the quality and efficiency of the concrete processing in the mixing plant.
[0003] Traditional batching silos typically consist of a single silo with four outlets and two discharge gates, or a single silo with two outlets and two discharge gates. When metering manufactured sand, all gates open simultaneously, discharging material from the silo's outlets at the same time. As the system sensor's reading approaches the set value, the dual-gate discharge immediately switches to single-gate discharge, and the silo's vibrator activates to assist discharging. A single pneumatic gate controls the two outlets, repeatedly opening and closing to ensure accurate final metering. This process is time-consuming. Due to the good flowability of sand, it's difficult to quickly and accurately measure and control the weight of manufactured sand in concrete mixing, thus affecting the quality of the concrete.
[0004] The vibrator is frequently activated during the material discharge process from the silo. Traditionally, a bracket is welded to the silo plate to mount the vibrator. As the vibrator is used for an extended period, the steel plate of the silo is prone to fatigue tearing, which affects the operation of the batching machine. Utility Model Content
