Problems solved by technology

[0005] However, when using the existing aggregate sampling device for aggregate sampling, only the aggregate near the side wall of the bin body can be obtained.
However, when the aggregate screened by the vibrating screen generally enters each storage bin, it will gradually form a conical pile in the bin body and accumulate up. The aggregates of different particle sizes within the particle size range are not evenly distributed, and the aggregates with larger particle sizes are concentrated near the side wall, which will cause the sampling results to not accurately reflect the actual situation of the aggregates in the silo

Abstract

The invention discloses an aggregate sampling device, a hot aggregate bin and an asphalt mixing plant. The aggregate sampling device comprises a sampling tube (1), screw conveying blades (2) and a rotary driving device, wherein a sampling port is arranged at one end of the sampling tube (1), the sampling port extends into the hot aggregate bin, the other end of the sampling tube (1) is fixed on the side wall of the hot aggregate bin, a mounting seat is arranged at the fixed end, an unloading outlet is arranged on the sampling tube (1), and the unloading outlet is connected with an unloading branch (5); the screw conveying blades (2) are mounted in the sampling tube (1) and used for conveying aggregate to the unloading branch (5); and one end of a rotating shaft of the screw conveying blades (2) is mounted on the mounting seat and fixedly connected with the rotary driving device, and the rotary driving device is used for driving the screw conveying blades (2) to rotate. By adopting the aggregate sampling device, the sampling depth can be increased, so that the accuracy in aggregate sampling can be further improved, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to an aggregate sampling device, a hot aggregate bin and an asphalt mixing station. Background technique [0002] The asphalt mixing plant is mainly used to produce asphalt mixture, and the production process of asphalt mixture plays a vital role in the forming quality of the pavement. The main raw materials of asphalt mixture include aggregate, mineral powder and asphalt. Aggregate is stone, which is one of the main raw materials of asphalt mixture. It is less than 3mm, 3mm~6mm, 6mm~11mm, 11mm~22mm, 22mm~35mm. The aggregates of different particle size ranges are screened by the vibrating screen and then enter into different storage bins of the hot aggregate bin. [0003] As the asphalt mixture has very high requirements on the accuracy of aggregate grading (mixing ratio of aggregates with different particle sizes in each storage silo), an aggregate sampling device is generally ...
