Production line for structuring yellow sand in components A of dry-mixed mortar through sand excavation accumulation yard

The utility model discloses a production line for structuring yellow sand in the components A of a dry-mixed mortar through a sand excavation accumulating yard. The production line comprises a sand shed (1) and is characterized in that one side of the sand shed (1) is sequentially provided with a grab truck (2), a loading hopper (3), a first belt conveyer (4), a rotary screen (5), a second belt conveyer (6), a second grab truck (7), a weightless measuring balance (8), a third belt conveyer (10) and a storage bin (11) with a discharging port. Due to utilization of the existing sand excavation accumulation yard, the production line can in situ process the yellow sand required by a double-component dry-mixed mortar and directly convey the yellow sand to a dry-mixed mortar production enterprise or the construction site of a building user, thereby saving the space of existing dry-mixed mortar special production enterprises for screening and stacking purchased ground sand, and meanwhile further reducing the product
