JPS589629Y2 - Stirring blade of portable electric stirrer - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a stirring blade for a portable electric stirrer for stirring construction cement, food paste/powder, and other materials that require kneading.

For example, during plastering work, plastering materials that are appropriately combined with cement, plaster, sand, aggregate, slats, waterproofing agents, adhesives, etc. are sprayed for the exterior and interior of buildings. In most cases, I would go to the site, put the plastering material in a metal box-shaped container called a ``fune'' or a ``trough-shaped container,'' and spray it with a gun while moving it appropriately using a portable electric stirrer. It is known that the mixture is stirred to a paintable state.

However, the stirring blades of conventional portable electric stirrers are iron plates,
Since it is made of a metal plate such as aluminum, even if the material in areas that do not touch the box-shaped container can be well stirred, the blades cannot reach the corners and cannot be uniformly stirred.

Moreover, if the blade is forced too close to the corner, it will hit the inner wall of the container, producing a metallic noise, and the blades will be bent or chipped, resulting in poor work efficiency and extreme danger.

In some cases, the stirring vessel is made of synthetic resin, but this has the disadvantage that it is easily damaged by contact with metal blades, and can leave holes if hit too hard.

The present invention improves the structure of the stirring blade of a portable electric stirrer in order to eliminate the drawbacks of the conventional one, and as explained below with reference to the drawings, at least the protruding blade part 11 is made flexible and the six-rotation blade body 1 is constructed. , one end 2□ of the rotating shaft 2 is attached indirectly via a mounting member 3, or in the past, the mounting member is omitted and it is directly attached, and a fluid circulation hole 4 is formed in the blade portion or near the blade portion. The summary is what was done.

Figures 1 and 2 show a disc-shaped blade body 1 having a plurality of radially protruding flat blade parts 11 held between a flange-type mounting member 3 and its receiving member 31 and fixed with bolts 5. .

Alternatively, the receiving member 31 can be omitted and the blade body 1 can be attached to the mounting member 3 with the bolt 5 in the opposite direction to that shown in FIG.

The lower end portion 21 of the rotary shaft 2 is inserted into the hole 6 provided in the mounting member 3, and the rotation prevention button is engaged and removed using the screw 7, which is historically known as mounting.

The twisted fluid flow holes 4 are formed on the surface of the blade body 10 near the blade portion 11.

Figures 3 and 4 show a configuration in which each protruding blade part 11 is formed into a twisted propeller shape, a mounting member 3 is provided in the center of the blade body 1, and a fluid communication hole 4 is formed in the surface of the blade part. .

It is also possible to integrally mold the blade base body 1 and the mounting member 3 from a flexible synthetic resin, and provide a reinforcing metal member 9 in the shaft hole 6.

Since the present invention has the above-mentioned configuration, in use, the upper part 22 of the rotating shaft 2 is attached to the chuck or socket of a hand-held drive source, specifically, an electric rotary tool such as a portable electric drill. When the container is placed in a box-shaped container and moved while being driven, the blades 11 bend along the inner wall of the container at the corners of the container where the blades 11 come into contact, Materials located in every corner of the container can be scraped out and mixed, which could not be achieved with metal blades, and a uniform and well-kneaded material can be obtained.

In addition, the holes 4 formed at or near the blade portion 11 of the blade root body allow the blade portion 11 to rotate during the rotation of the blade root body 10.
The upper and lower materials partitioned by the hole 4 flow vertically through the hole 4, and the hole edge 41 also assists in the impact action on the material, further increasing the stirring effect.

Since the blade part 11 is made of flexible synthetic resin, there is no risk of damage even if the blade part 11 hits the inner wall of the container, so it is safe, and the noise caused by contact is prevented, making it easy to work.

Note that if the entire blade body 1 is molded from synthetic resin such as flexible urethane resin in order to make the blade part 11 flexible, the central part will also be flexible, and its -qt will have a so-called waist. However, by providing the flange-type mounting member 3, the strength of that part is increased and can sufficiently withstand rotational resistance.

In the thin ice design, it is also possible to connect a plurality of blade bodies 1 and attach them to the rotating shaft 2, and this arrangement is particularly suitable for use in a stirring vessel with a deep bottom.
