Aggregate weighing system for asphalt mixture

Abstract

The invention discloses an aggregate weighing system for an asphalt mixture, which comprises a plurality of aggregate bin assemblies which are arranged in parallel at intervals. An aggregate weighing hopper is arranged below each aggregate bin assembly. Weighing sensors are arranged in the aggregate weighing hoppers. Aggregate weighing hopper door opening cylinders are arranged below the aggregate weighing hoppers. Each aggregate bin is provided with a big batching door and a small batching door. A big batching door control cylinder is arranged in the big batching door. A small batching door control cylinder is arranged in the small batching door. Due to the adoption of the aggregate weighing system for the asphalt mixture, which is disclosed by the invention, the defects of low weighing accuracy, poor product quality and the like in the prior art can be overcome, so that the advantages of high weighing accuracy and high product quality are realized.

Description

technical field [0001] The invention relates to asphalt mixture metering technology, in particular to an asphalt mixture aggregate metering system. Background technique [0002] At present, asphalt mixture is composed of various aggregates, powder, and asphalt mixed in a certain proportion, and the measurement accuracy of each aggregate directly affects the quality of asphalt mixture. [0003] Because the size of the aggregate flow will directly affect the amount of aggregate flying due to the level of the aggregate bin, thus affecting the accuracy of measurement. In the prior art, the compensation method of fixing the amount of flying material is adopted, and the measurement accuracy is low, which affects the quality of asphalt mixture. [0004] It can be seen that in the process of realizing the present invention, the inventors have found that at least there are defects such as low measurement accuracy and poor product quality in the prior art. Contents of the invention...
