Discharge door device for double-horizontal-shaft concrete mixer

Abstract

The invention discloses a discharge door device for a double-horizontal-shaft concrete mixer, which comprises a discharge door main body and a drive mechanism, wherein the discharge door main body comprises two sector plates, an arc door plate, a V-shaped plate, a long shaft and a short shaft; the two sector plates are welded at the two ends of the arc door plate respectively; the V-shaped plate is welded with the inner side of the arc door plate; the long shaft and the short shaft are welded on the two sector plates respectively; welding centers are near the opening end of a discharge door; a second mounted bearing is mounted on the short shaft and fixed on a right side wall of a double-horizontal-shaft concrete mixing drum and can move up and down; a first mounted bearing is mounted on the long shaft; a mixing drum side wall ribbed plate is welded on a left side wall of the double-horizontal-shaft concrete mixing drum; a bearing mounting plate is welded on the mixing drum side wall ribbed plate; and the first mounted bearing is fixed on the bearing mounting plate and can move up and down along the bearing mounting plate. The discharge door device is good in sealing effect and high in reliability, and has the effects that the door is looser to open and tighter to close gradually, the wear compensation is facilitated, and the door opening efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of concrete mixers, and in particular relates to a discharge door device for a twin-shaft concrete mixer. Background technique [0002] The twin-shaft concrete mixer has many advantages such as high productivity and strong adaptability, and has become the leading model in the current concrete mixing equipment. As one of the key components of the twin-shaft concrete mixer, the discharge door device directly affects the production efficiency, mixing quality and work reliability of the mixer. The discharge door device of the existing twin-shaft concrete mixer is usually embedded in the discharge port at the bottom center of the mixer cylinder, and the discharge port is opened and closed by the rotation of the discharge door device around its own axis. Since this kind of discharge door device mainly relies on the close fit between the arc-shaped discharge door plate and the barrel at the discharge port of the m...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art above, and provide a discharge door device for a twin-shaft concrete mixer, which has a compact structure, reasonable design, and is easy to use and operate, and can effectively solve the problem of sealing problems existing in the existing discharge door device. The eccentric design not only improves the sealing effect of the discharge door and improves the working reliability of the mixer, but also facilitates the overall adjustment of the discharge door and easy wear compensation, and also makes the discharge door more effective. The effect of opening looser and closing tighter, the door opening efficiency is high, and the door closing performance is good
