Description

  The present invention relates to a stirrer that stirs a gas, liquid, sol-like solution, or the like in a container, and in particular, while a propeller slides along a twisted surface of a twisting rod by manually rotating a rotating support portion. The present invention relates to an agitator that rotates and agitates.

  FIG. 7 is a front sectional view of a stirrer according to a conventional example. As shown in FIG. 7, the rod 242 is inserted into a loose fitting hole 253 pierced in the center of the mounting base 205, and is supported so as to be tilted and raised by a bearing 255 of a holding block 254 fixed on the mounting base 205. The urethane packing 256 is provided on the holding block 254 and is fixed by the presser fitting 257.

The stirrer 204 is provided with a stopper rod 206 that hangs parallel to the rod 242, and the stopper rod 206 is supported by screws on the upper arm 261 of the rod 242 and the base of the handle 241. In addition, the rod 242 slightly above the stirring blade 243 is provided with a stirring auxiliary body 245 that protrudes three stirring bars 451 bent in the horizontal direction, and any one of the stirring bars 451 has an inner periphery of the container 201. An abutment guide 246 that can abut against the projection protrudes obliquely downward.
In this way, the stirrer 204 can be tilted and moved up and down, and can be stirred with the rotary blades 243 and the stirring rod 451 to every corner of the container 201, and the contact guide 246 is in contact with the inner periphery of the container 201 and adhered. Since the solid lump can be safely removed and stirred, and supported by the mounting base 205, the stirrer 204 can be held lightly and easily operated, and the container 201 can be easily detached and excellent in workability.

  In addition, the position of the stirring blade can be easily displaced by grasping the handle and tilting it, or tilting it up and down, etc., and this displaceable stirring can remove and stir the solid lump attached to the inner periphery of the container. Since the inner bottom of the container is a gently curved concave surface, the inner peripheral portion of the lower end of the container can be uniformly stirred.

Further, during the operation of the agitator, the stopper rod provided in parallel with the rod by the rotational force abuts against the mounting base and is not swung further. In addition, when the stirrer is tilted and displaced, the abutment guide provided slightly above the agitation blade rotates and abuts against the inner periphery of the container, so that the abutment guide scrapes off the solid mass adhering to the inner periphery. Can be stirred. Furthermore, since the stirring rod also rotates simultaneously with the stirring blade, the stirring effect is good, and the mounting structure of the contact guide is simplified by projecting the contact guide on the stirring rod.
