Abstract

The invention relates to an automatic feeding system for a raw material bin of an asphalt mixing plant, and belongs to the field of asphalt feeding. The automatic feeding system comprises a feeding tower, and a discharging pipe and a returning pipe are fixed to the peripheral face of the feeding tower; and the bottom end of the discharging pipe is fixedly connected with the peripheral face of the material returning pipe. A discharge hole is formed in the outer circumferential surface of the return pipe, and a filter screen is fixed on the inner circumferential surface of the discharge hole; a scraping plate is arranged on the bottom surface of the filter screen in the length direction of the return pipe, a brush is fixed to the top of the scraping plate; and a driving device for driving the scraping plate to move is arranged below the return pipe. The filter screen cleaning device has the effect of conveniently cleaning the filter screen.

Description

technical field [0001] The present application relates to the field of asphalt feeding, in particular to an automatic feeding system for a raw material warehouse of an asphalt mixing plant. Background technique [0002] At present, aggregates of various specifications, binders and fillers are mixed in a certain proportion to form asphalt mixture, and the concrete slab formed after the asphalt mixture is formed is asphalt concrete. [0003] Related technologies can refer to the Chinese utility model patent with the authorized announcement number CN208104968U, which discloses a feeding and mixing device for asphalt concrete production, including a base and a mixing drum. With bitumen storage tank. A filter screen is arranged in the feed cylinder. During the asphalt blanking process, the filter screen will filter the larger volume of asphalt raw materials to facilitate the subsequent mixing of asphalt. [0004] In view of the related technologies mentioned above, the invento...
