Claims

[Scope of Claim for Utility Model Registration] (1) In a stirring device structure in which a stirring blade is attached to the end of a rotating arm as a stirring means constituting a rotary kneading type concrete mixer, the downward direction of the base of the stirring blade and the direction of the outer circumference of rotation. a portion is formed as a replacement member separate from the blade base;
A stirring device for a concrete mixer, characterized by being equipped with a structure for attaching and detaching the blade base. (2) The replacement members in the lower direction and the rotational outer circumferential direction of the removable stirring blade base have a partially reinforced structure in which they are reinforced with a material that has greater wear resistance than the stirring blade base. An agitation device for a concrete mixer as set forth in claim 1 of the utility model registration claim. (3) The attachment/detachment structure of the replacement member is characterized in that the blade base and the reinforcing structure portion are each provided with mutually opposing cutout steps, and the notch steps are made to face each other and bolts are connected to connect them by tightening. A stirring device for a concrete mixer according to claim 1 or 2 of the utility model registration claim. (4) The attachment/detachment structure for the replacement member is such that a tenon-like protrusion is formed on either one of the blade base and the reinforced structure portion, and a recess into which the tenon-like protrusion is fitted is formed on the remaining one; The stirring device for a concrete mixer according to claim 1 or 2, characterized in that the convex portion is inserted into the concave portion and a bolt is connected and tightened for connection.
