The invention belongs to the technical field of concrete ingredient conveying, and relates to a concrete ingredient conveying device which comprises a
barrel, an
auger shaft, an end cap, an end plate, a spring and a plurality of studs. The downstream end of the cylinder is an open end, and a plurality of edge arms are formed on the outer wall of the cylinder. The end cap is arranged at the open end of the
barrel and provided with an annular groove capable of being matched with the
barrel in an inserted mode and a shaft hole correspondingly matched with the
auger shaft, and the end cap can move in the axial direction relative to the barrel. The inner bottom surface of the end cap forms an arc surface, and a plurality of strip-shaped protruding teeth are distributed on the inner side wall of the end cap. The end plate and the spring are both arranged on the
auger shaft in a sleeving mode, and the two ends of the spring make contact with the end plate and the end cap respectively. Through holes matched with the two ends of the stud are formed in the radial
flange on the end plate and the edge arms, and the stud can limit the distance between the barrel and the end plate. According to the invention, the
extrusion condition of materials at the end part of the barrel can be improved, so that the materials bear elastic
extrusion force and are continuously segmented and dispersed, the phenomenon of excessive material
caking can be inhibited, and the cleaning period is prolonged.
