2. Description of the Related Art A mixer for mortar or the like in which a stirring blade is provided at the bottom of a cylindrical stirring tank having an open upper end and the mortar material charged from the upper end is stirred by the stirring blade Workers may inadvertently put their hands in the tank and get injured by the stirring blades. For this reason, it is required to cover the upper end surface of the stirring tank with a cover for the purpose of ensuring the safety of workers. This safety cover was usually formed by combining appropriate wire rods made of iron or the like at intervals of about 20 cm to form a shape substantially equal to the shape of the upper end surface of the stirring tank.

[Problems to be solved by the device] However, this safety
Bars have the following challenges: First, open only the lid
As a problem, when opening and closing the lid rotates along the vertical direction.
Therefore, in the opening / closing operation, the opening / closing lid is lifted.
Thus, it is necessary to rotate. Therefore, short
In the case of a large person or a large stirring tank, the back stretches and the open / close lid
It is necessary to lift the part and it is extremely workable
Is bad.

Second, there is a problem when the opening of the stirring tank is fully opened.
As a subject, centering around the rotation axis and connecting to the main body
When the opened and closed lid is rotated in the horizontal direction, it rotates.
The radius is large, and it is large around the stirring tank due to rotation.
It requires space and is not suitable for narrow work sites.

For smooth rotation, the main body and the opening / closing lid are
Needs to be floated above the upper end of the stirring tank. Especially the body
The hanging edge that extends downward is provided on the outer periphery of the
If not, float above the top of the stirring tank.
Therefore, it cannot be fully opened. Therefore, with a foot pedal
There is a jack, but such a jack

Furthermore, through the shaft receiving 18 and swing arm 19, since connects the central outer periphery 11b of the mounting portion 16 and the main body 1, the bearing 18 and the swing arm 19 as a hinge, the body The part 1 and the opening / closing lid part 2 can be rotated. More specifically, as shown in FIG.
Is fully opened and placed on the main body 1, and the main body 1 and the opening / closing lid 2 are rotated about the position of the fixing device 13 as indicated by an arrow y. As a result, the main body 1 and the opening / closing lid 2 are held in the stirring tank k while the fixing state of the fixing device 13 is maintained.
Can be hung outside the. Therefore, the fixing device 1
The entire upper end surface of the stirring tank k can be opened while maintaining the fixed state according to 3, and the safety cover a does not interfere even when the inside of the stirring tank k is washed, for example.
Then, by rotating in the direction opposite to the arrow y direction, the original state can be easily restored, and efficient work becomes possible. The U-shaped stoppers 12, 12 on both ends of the outer periphery of the main body 1 described above are mounted so as to straddle the upper end j of the agitation tank k, and therefore rotate in the direction opposite to the arrow y direction. Only by moving, the inverted U-shaped stoppers 12, 12 are fitted on the upper end j of the stirring tank k, and no special work is required. Moreover, even if such a rotatable fixing device is provided on the conventional integrated safety cover, the turning radius becomes large as shown by the arrow z, and the turning work is difficult and a large force is required. However, in some cases, the rotation itself may become impossible at a narrow work site, but the present invention has solved such a problem.
