Description

Technical Field

[0003] The Chinese utility model patent with the authorization announcement number CN219748494U discloses a concrete mixing device, including a casing and a processing mechanism; the casing is respectively provided with a feed port and a discharge port; the casing is provided with a screening chamber, a material transport chamber and a mixing chamber, the feed port is communicated with the screening chamber, the screening chamber is communicated with the material transport chamber, the material transport chamber is communicated with the mixing chamber, and the discharge port is communicated with the mixing chamber; the processing mechanism includes a screening part, a material transport part, a transmission part and a mixing part; the screening part is arranged in the screening chamber and is located below the feed port, the material transport part is vertically arranged in the material transport chamber, and is used to introduce the screened material into the mixing chamber; but The prior art still has the following technical problems: first, the material slides on the inclined surface through the screening chamber into the material transport chamber, and the motor drives the spiral transport rod to transport the material upward. During the transportation process, the material will fall due to its own weight. There is a gap between the spiral transport rod and the material transport chamber. When the material is transported to the circular hole opened at the upper end of the mixing chamber, the circular hole and the movement trajectory of the spiral transport rod do not intersect.
