Description

Technical Field

[0001] The utility model relates to the technical field of concrete sand and gravel aggregate measuring equipment, in particular to a mobile sand and gravel aggregate measuring scale. Background Art

[0002] Aggregate weighing scales are widely used in the concrete mixing industry. According to the grading requirements of concrete, a variety of aggregates need to be weighed. At present, there are two ways to weigh aggregates. One way is to equip the discharge ports of multiple material bins with aggregate weighing scales and measure them separately. This requires the configuration of multiple aggregate weighing scales, which is costly. The other way is to use a single aggregate weighing scale for cumulative measurement. The cumulative measurement method is to use the same aggregate scale to weigh another or several materials after measuring one type of aggregate. However, in order to facilitate the feeding of multiple aggregates to the aggregate weighing scale, the weighing bin on the aggregate weighing scale is generally designed as a large-sized narrow structure. However, an overly long weighing bin will affect its structural strength and easily increase its occupied area. Therefore, the aggregate weighing scale of this structure has some restrictions on the distance to the material bin, and it is difficult to cope with too many types of materials.
