  Hereinafter, first, Example 1 of the present invention will be described in detail with reference to FIGS.

  A is a large-diameter screw for stirring a fluid material having a diameter of about 12 cm, which is composed of a metal screw main portion 1 and a protective ring 2 made of metal, and is used for stirring a fluid material such as a sealing material having a relatively high viscosity. It is.

The screw main body 1 has a rotation shaft insertion hole 3 at the center of a substantially circular main plate 1 ', and horizontally extends six main wing pieces 4 ... on the outer periphery of the main plate 1' every 60 °. Has formed.
The tip side of the main wing piece 4... Is bent downward to form a stirring piece 4 ′. This stirring piece 4 '... is in a twisted state with one side 4a ... positioned outside the other side 4b ... (Fig. 2).
The protective ring 2 is fixed by welding or the like on the outer periphery of the lower end of the main wing piece 4..., That is, the lower end of the one side 4 a.

  5... Are six auxiliary wings formed so as to extend horizontally outward between the main wing pieces 4... And shorter than the main wing pieces 4. It is a piece.

  Further, washer receivers 6 and 6 are formed on the upper surface of the screw main body 1 by cutting up opposing portions in the vicinity of the outside of the rotary shaft insertion hole 3.

The fluid material agitating large-diameter screw A having the above-described configuration is connected to the rotating shaft R of a conventionally known fluid material agitator inserted through the rotating shaft insertion hole 3 from the upper and lower sides of the screw main portion 1 with washers 7 and 7. And are fastened and fixed by nuts 8 and 8 (FIGS. 3 and 4).
At this time, the washer receivers 6 and 6 of the screw main body 1 and the washer 7 on the upper surface side come into contact with each other (FIG. 3).

  Since the large-diameter screw A for stirring the fluid material has the protective ring 2 attached to the outer periphery of the main wing piece 4..., That is, the lower end of the stirring piece 4 ′. If the fluid material in the container is agitated, the agitating piece 4 'does not directly contact the side or bottom of the soft film difficult-to-be-sustained container. It is possible to prevent the screw A from rotating and the hard-to-stand container from being damaged.

Further, the large-diameter screw A for agitating the fluid material is bent downward from the main plate 1 ′, and the outer fluid material is moved inward (to the lower surface side of the main plate 1 ′) by the agitated stirring piece 4 ′. The structure is such that the fluid material is fed in horizontally or the fluid material inside is fed out horizontally, and the main plate 1 'is provided so that the vertical flow of the fluid material is suppressed as much as possible. It has become.
Accordingly, since it is possible to prevent bubbles from being mixed in due to the vertical flow of the fluid material during stirring, it is suitable for stirring a fluid material such as a sealing material in which mixing of bubbles is inconvenient.

Reference numeral 9 denotes a difficult-to-support container fixing base for fixing the difficult-to-support container so that it does not rotate during the above-described stirring operation (FIG. 5).
This is an annular engagement in which the engaging peripheral wall 10a on the outer periphery of the bottom portion of the difficult-to-be-sustained container 10 and the engaging protrusions 10a 'on the bottom surface of the difficult-to-be-sustained container 10 are received in the center on the rectangular flat plate base 9a. The entrance groove 9b and the engagement hole 9b 'are formed.
In addition, L-shaped fixing plates 9e and 9e made of stainless steel, aluminum, plastic, or the like and made up of an attachment portion 9c and an upright portion 9d are attached to the left and right sides of the annular engagement groove 9b.

A plurality of screw holes 9f are formed in the attachment portion 9c, and are attached to the pedestal 9a so that the positions of the two fixing plates 9e and 9e can be fixed in accordance with the diameter of the difficult-to-support container 10. ing. Further, a plurality of screw holes 9g... Are formed in the upright portion 9d, and the height of the expansion and contraction plate 9h attached to the upright portion 9d can be made difficult to stand by screwing a screw into one of them. It can be fixed according to the height of the conductive container 10.
9i is a notch formed in the upper edge of the expansion / contraction plate 9h, and a grip portion 10b formed on the upper opening edge of the hardly self-supporting container 10 can be engaged therewith. Yes.

In the fluid material agitation work of the fluid material stored in the difficult-to-be-sustained container, the difficult-to-be-supported container 10 is fixed to the difficult-to-be-sustained container fixing base 9 so as not to rotate. That is, the engaging peripheral wall 10a of the difficult-to-be-sustained container is engaged with the annular engaging groove 9b, and the engaging protrusions 10a 'are engaged with the engaging holes 9b'. The parts 10b and 10b are engaged with the notches 9i of the expansion and contraction plate 9h and fixed on the top (FIGS. 6 and 7).
Then, the worker puts the large-diameter screw A for agitating the fluid material attached to the agitator for the fluid material on the pedestal 9a with both feet so that the hardly self-supporting container fixing base 9 does not move. It is inserted into a hardly self-supporting container and agitation is performed (FIG. 7).
Further, the difficult self-supporting container fixing base 9 itself may be fixed to the floor or the ground to perform the stirring work.

  Accordingly, when the fluid material is agitated, it is possible to prevent the hardly self-supporting container itself from being rotated by the rotation of the fluid material agitating large-diameter screw A.

9 'shown in FIG. 8 is another example of a difficult-to-be-sustained container fixing base.
The hardly self-supporting container fixing base 9 ′ includes a circular support base 9′b on which the difficult self-supporting container 10 is mounted at the center of a rectangular and flat base 9′a.
The support base 9′b has a holding member 9′c... That fastens and holds the side surface of the bottom portion of the placed difficult-to-be-sustained container 10 so as to rotate. It is supposed to hold so as not to.
The holding member 9′c... Has a structure in which the hardly self-supporting container 10 is mounted on the base 9 ″ c... And moves toward the center of the base 9′a to fasten the side surface of the container 10.
Even when the agitation work is performed using the difficult-to-be-sustained container fixing base 9 ′, the operator can sit on the pedestal 9′a with both feet and attach the fluid material agitator to the fluid material agitator. The rotation of the hardly self-supporting container itself can be prevented by inserting the diameter screw A into the difficult self-supporting container and performing the stirring operation.
Further, the difficult self-supporting container fixing base 9 ′ itself may be fixed to the floor or the ground to perform the stirring work.

The fluid material agitating large-diameter screw A is suitable for agitating a sealing material or the like. However, when a fluid material such as a paint having a lower viscosity is agitated, the agitating piece 4 ′. It is preferable to increase the number of main wing pieces 4.
[Modification 1]

  FIG. 9 shows a fluid material stirring large-diameter screw B according to the first modification of the first embodiment.

This is only the point that only three of the auxiliary blade pieces 5... That were provided with the six large-diameter screws A for stirring the fluid material are placed in a state where they are suspended downward. Therefore, the same reference numerals are assigned to the same parts, and detailed description of the configuration is omitted.
The auxiliary blade pieces 5 are suspended in a twisted state so that one side thereof is located outside the other side, like the stirring pieces 4 '.
However, the auxiliary wing piece 5... May be suspended without being twisted so that the one side and the other side are positioned concentrically.

  Since the large diameter screw B for agitating the fluid material has a protective ring 2 attached to the outer periphery of the lower end of the agitating piece 4 '..., like the large diameter screw A for agitating the fluid material, this is used for the fluid material. If the fluid material in the difficult-to-stand container is agitated and attached to the stirrer, the side or bottom of the difficult-to-support container made of soft film will not directly hit the stirring piece 4 '. The part is caught and rotation of the screw B is prevented, and the hard-to-support container is prevented from being damaged.

Further, since the auxiliary blade pieces 5 are suspended downward, the stirring pieces 4 '... not only stir the fluid material, but also at the position inside the stirring pieces 4' ... The fluid material can be agitated by the pieces 5... And the agitation work can be performed efficiently.
In particular, in a stirring operation of a fluid material having a high viscosity such as a sealant, a considerable force is required to move the screw laterally during stirring. According to the large-diameter screw B for stirring a fluid material, Thus, since the fluid material located in the protective ring 2 can be stirred by the auxiliary blade pieces 5..., It is easy to stir while moving the screw B laterally.
Moreover, since the screw B is configured to suppress the flow of the fluid material in the vertical direction by the main plate 1 ′, it is possible to prevent bubbles from being mixed into the fluid material such as a sealing material.
[Modification 2]

  FIG. 10 shows a large-diameter screw C for agitating a fluid material according to Modification 2 of Example 1 described above.

This is because the large-diameter screw A for stirring the fluid material is in a state where six auxiliary blade pieces 5 are suspended downward, and on the outer periphery of the lower end of each of the suspended auxiliary blade pieces 5. Since only the point where the protective ring 15 is fixed by welding or the like is different, only the same reference numerals are given to the same portions, and detailed description of the configuration is omitted.
The auxiliary wing pieces 5 are preferably suspended in a twisted state, like the large-diameter screw B for agitating the fluid material in the first modification, but are suspended without being twisted. It may be a thing.

  Since the large diameter screw C for stirring the fluid material has a protective ring 15 attached to the outer periphery of the lower end of the auxiliary blade piece 5..., In addition to the same effect as the large diameter screw B for stirring the fluid material of the first modification example. In addition, the auxiliary wing piece 5 does not entrain the side wall or bottom of the difficult-to-stand container, and prevents the screw C from rotating and the difficult-to-support container from being damaged. Play.

In addition, since the main plate 1 ′ suppresses the vertical flow of the fluid material, it is possible to prevent bubbles from being mixed into the fluid material such as a sealing material.
[Modification 3]

  FIG. 11 shows a large-diameter screw D for stirring a fluid material according to Modification 3 of Example 1 described above.

This is the only difference from the large-diameter screw A for agitating the fluid material in that the six auxiliary wing pieces 5... Are staggered, three are raised upward, and the other three are suspended downward. Therefore, the same reference numerals are assigned to the same parts, and detailed description of the configuration is omitted.
The auxiliary wing pieces 5 are preferably twisted, but are not twisted, that is, the one side 5 and the other side of the auxiliary wing pieces 5 are concentrically positioned. May be.

  The fluid material stirring large-diameter screw D has the same effect as the fluid material stirring large-diameter screw A. That is, since the protective ring 2 is attached to the outer periphery of the main wing piece 4..., If the fluid material in the difficult-to-stand container is stirred by attaching it to the stirrer for fluid material, the difficult-to-stand container made of soft film Since the stirring piece 4 '... does not directly contact the side or bottom of the container, the side wall or the material container may be caught in the screw D, and the rotation of the screw D may be disabled or the difficult-to-stand container may be damaged. Is prevented.

  Second, since the auxiliary blade piece 5... Is suspended downward like the large-diameter screw B for stirring the fluid material, the position of the auxiliary blade piece 5. This fluid material can also be stirred, the stirring work can be performed efficiently, and the lateral movement during stirring is easy.

  In addition, since the main plate 1 ′ suppresses the vertical flow of the fluid material, it is possible to prevent bubbles from being mixed into the fluid material.

  Thirdly, by raising the auxiliary blade pieces 5... Upward, there is an effect that the shake of the stirrer during the stirring of the fluid material is reduced and stabilized.

  The six auxiliary wing pieces 5 may all be raised upward.

  In addition, unlike the large-diameter screw C for stirring the fluid material, a protective ring is not provided on the outer periphery of the auxiliary blade piece 5... When it adheres, there exists an advantage that the washing | cleaning etc. are easy to perform.

Next, Embodiment 2 of the present invention will be described in detail with reference to FIG.
E is composed of a metal screw main portion 21 and metal protective rings 22a and 22b, and has a diameter of about 12 cm used for stirring fluid materials such as paint having a viscosity lower than that of the sealing material. It is a large diameter screw.

The screw main body 21 has a rotary shaft insertion hole 23 at the center of a substantially circular main plate 21 ', and a total of twelve stirring pieces 24, 25,. It is formed in a state where it is alternately raised and drooped.
These stirring pieces 24..., 25... Are twisted with their one side 24 a..., 25 a.

Of these, the protective ring 22a is fixed by welding or the like on the outer periphery of the upper end of the agitated piece 24... That is, the upper end of the one side 24 a of each agitated piece 24.
Further, the protective ring 22b is fixed by welding or the like on the outer periphery of the lower end of the suspended stirring piece 25, that is, the lower end of the one side 25a of each stirring piece 25.

  Washer receivers 26 and 26 are formed on the upper surface of the screw main body 21 by cutting up opposing portions in the vicinity of the outside of the rotary shaft insertion hole 23.

The large-diameter screw E for agitating the fluid material having the above-described configuration is inserted into the rotation shaft R of a conventionally known fluid material agitator inserted through the rotation shaft insertion hole 23 from above and below the screw main body 21 via washers. It is fixed by tightening with a nut.
At this time, the washer receivers 26 and 26 of the screw main body 21 and the washer on the upper surface side come into contact with each other.

  Since the large diameter screw E for agitating the fluid material has protective rings 22a and 22b attached to the outer periphery of the agitating pieces 24..., 25. If the fluid material is agitated, the agitating pieces 24..., 25... Do not directly hit the sides or bottom of the soft film difficult-to-be-sustained container. It becomes possible to prevent the rotation of E from becoming impossible and the independence container from being damaged.

  The large-diameter screw E for agitating the fluid material is suitable for agitating a paint or the like. However, when agitating a fluid material such as a sealing material having a higher viscosity, the agitating pieces 24... It is preferable to reduce the number of.

  Next, a third embodiment of the present invention will be described in detail with reference to FIGS.

The fluid material agitating screw device of the present embodiment is the same as the fluid material agitating large-diameter screw (first fluid material agitating screw) A of Example 1, and the diameter is smaller than that, and the fluid is agitated on the rotating shaft R. It consists of a fluid material agitating small diameter screw (second fluid material agitating screw) F that is attached together with the material agitating large diameter screw A, and is mainly used for agitating fluid materials such as paint.
The fluid material agitating large-diameter screw A is as described in the first embodiment, so that the description of the configuration is omitted, and the fluid material agitating small-diameter screw F will be described below.

  The small diameter screw F for stirring the fluid material has a diameter of about 7 cm including a metal screw main portion 31 and metal protective rings 32a and 32b.

The screw main body 31 has a rotation shaft insertion hole 33 at the center of a substantially circular main plate 31 ′, and six stirring pieces 34, 35,... At 60 ° intervals on the outer periphery of the main plate 31 ′. In addition, they are formed in a state where they are alternately raised and lowered vertically.
These stirring pieces 34... 35... Are twisted with their one side 34 a... 35 a... Positioned outside the other side 34 b.

The protective ring 32a is fixed by welding or the like on the outer periphery of the upper end of the stirring piece 34... Raised upward, that is, the upper end of the one side 34a of each stirring piece 34.
Further, the protective ring 32b is fixed by welding or the like on the outer periphery of the lower end of the stirring piece 35... That is suspended downward, that is, the lower end of the one side 35a of each stirring piece 35.

  Washers 36 and 36 are formed on the upper surface of the main plate 31 ′ by raising and facing opposite portions in the vicinity of the outside of the rotary shaft insertion hole 33.

  The fluid material agitating large-diameter screw A is attached to the rotating shaft R of the fluid material agitator inserted into the rotating shaft insertion hole 33 with nuts 38 via upper and lower washers 37 of the screw main body 1, and The fluid material agitating small diameter screw F is located in the protective ring 2 of the large diameter screw A directly below the fluid material agitating large diameter screw A and is inserted into the rotary shaft insertion hole 33. The nut 40 is attached to the rotating shaft R of the material stirrer via the upper and lower washers 39 of the screw main body 31 (FIG. 14).
