concrete mixer

Abstract

The invention discloses a concrete mixer, comprising a mixer shell, the upper end surface of the mixer shell is open, the inner wall of the opening end is provided with an internal thread, the opening end is threaded into a rotating cover, and the outer wall of the rotating cover engages with the internal thread of the opening end, so that A driving motor is installed on the top of the rotating cover, the motor shaft of the driving motor is connected to a connecting rod through a coupling, a first rotating rod is telescopically loaded into the connecting rod, and the top of the first rotating rod is telescopically loaded into the In the connecting rod, at the bottom of the first rotating rod, more than one first stirring blade is arranged around the first rotating rod. The present invention can use the height of the rotating cover relative to the mixer shell to adjust the angle between the first stirring piece and the second stirring piece, and then adjust the stirring width of the whole stirring piece, and realize the lifting type opening and closing stirring during stirring, Stirring efficiency is greatly reduced. When not in use, the entire stirring rod is in the shape of a "one", which is easy to carry and clean.

Description

technical field [0001] The invention relates to the construction field, in particular to a concrete mixer. Background technique [0002] Concrete mixer is a commonly used material processing device on construction sites. Inside the concrete mixer, the drive motor is used to drive the mixing shaft and the mixing blades installed on the mixing shaft to rotate, and the mixing blades are used to stir. There are many deficiencies in the above structure, such as: mixing blades and mixing The shaft is welded and fixed, so it is bulky and not easy to carry. Because of its irregular shape, it is very inconvenient to clean; moreover, the length of the stirring blade is fixed. When stirring, the radius of stirring has been determined, and post-control adjustment cannot be performed. , and there is only a single fixed rotation stirring mode, so the stirring efficiency is low, and there are many deficiencies in its use. Contents of the invention [0003] The technical problem to be so...
