DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blade mounting device used for scraping blades and the like used for bean jam, yokan, soup, sauce and the like or other kneaders for food production. The present invention relates to a blade mounting device that is easy to disassemble and assemble with a blade 2.

[0002]

2. Description of the Related Art In order to manufacture bean paste, yokan, soup, sauce, etc., in a heating pot with a stirrer for boiling red beans or other beans or other liquids, the inner surface of the heating pot is scorched, and the scorching occurs inside the heating pot. When mixed with food, its commercial value is significantly reduced. In order to prevent such scorching, it is necessary to frequently scrape the inner surface of the kettle during this heating.
The scraper that performs such an operation is one in which a plurality of circumferentially spaced scraping blades are attached to the tip of an arm fixed to a rotary shaft inserted into the shuttle.

FIG. 21 is a cross-sectional view schematically showing an entire conventional blade mounting apparatus, FIG. 22 is an enlarged cross-sectional view of a main part thereof, and FIG.
FIG. 24 is a top view, FIG. 24 is a bottom view of the blade portion, and FIG.
Are exploded perspective views showing a plurality of scraping blades 83, 8 at circumferentially spaced ends of arms 82, 82,... Fixed to a rotating shaft 81 inserted into the center of the shuttle 80, respectively.
3, ... attached. As shown in detail in FIG. 22, the blade mounting device includes arms 82, 82,.
At the tip of the blade mounting member 8 made of stainless steel (or the same below for corrosion-resistant materials such as aluminum and titanium)
4 is supported by a shaft 85 so as to rotate toward the inner surface of the shuttle 80, and the blade mounting member 84 is fitted into the cylinder hole 79 of the arm 82 to slide. The pin 87 is repelled by the spring 86 so as to be operated toward the inner surface of the shuttle 80. The tip of the shaft 85 is formed in a fork shape, and a hook 85a for preventing the escape is pivotally attached to the tip between them. The scraping blade 83 made of Teflon (or an acid-resistant and heat-resistant sliding material) is sandwiched by a sandwich plate 89 made of stainless steel at the tip of the blade mounting member 84, and a bolt 90
And a nut 91. In the drawing, reference numeral 92 denotes a hole for inserting a bolt 90 provided on the blade mounting member 84;
3 is a hole for inserting a bolt 90 provided on the scraping blade 83, 94 is a hole for inserting the bolt 90 provided on the sandwiching plate 89, and 95 is a spring for repelling the hole.

[0004]

However, such a conventional blade mounting device requires a large number of bolts 90 and nuts 91, which are separate components, requires tools such as a screwdriver and a large number of tightening operations, and is extremely disassembled and assembled. It is troublesome,
Troubles occurred due to loss and drop of other parts such as nuts, which caused an accident. When the disassembly and assembly are troublesome, the cleaning of the apparatus becomes insufficient, which is not only unsanitary, but also the residue of the previous process is mixed into the next process, and the product of the next process has color, smell, etc. To reduce product value.

The present invention eliminates such a drawback, and provides a blade mounting apparatus which does not require tools such as a screwdriver or other parts such as screws and nuts and is extremely easy to disassemble and assemble.
