The other end of the jig bar 324 penetrates through the fourth hinge portion 325 and protrudes in the direction of the gear portion body a (121a).

The user can adjust the rotation of the rotary shaft 200 in the yaw direction using the jig 320 described above.

The jig 320 and the window 130 are located on opposite sides of the gear body body a 121a. In other words, the window 130 is formed on the surface of the gear portion 120, that is, the outer surface of the gear body body 121a, which opposes the jig 320. Therefore, when the inside of the gear body a (121a) is checked through the transparent plate 131 of the window 130, the jig 320 is not disturbed.

On the other hand, a cylindrical portion 184 is protruded between the two first hinge portions 183 spaced apart from each other.

The cylindrical portion 184 is formed near the center of the first frame body 182 and is hollow. Therefore, the inside of the cylindrical portion 184 is inserted into the stirring tank 300 through the rotating shaft 200, the outer cylinder 210, and the pipe 220.

A description will be given of the rotation shaft 200, the outer cylinder 210, the pipe 220, the sleeve 230 and the like, which are inserted into the stirring tank 300 through the first frame 181 and the second frame 190 do.

A part of the rotary shaft 200 is inserted into the gear portion 120 and horizontally coupled to the gear portion 120 and the remaining portion is inserted into the stirring tank 300 through the first frame 181 and the second frame 190.

The rotating shaft 200 passes through the inside of the hollow tube 141 and passes through the inside of the pipe 220 to be inserted into the stirring tank 300.

The impeller 202 is rotatably coupled to the end of the rotating shaft 200 inserted into the stirring tank 300.

One end 221 of the pipe 220 is inserted and screwed into the inner edge 142 of the hollow tube 141.

The pipe 220 is disposed to pass through the first frame 181 and the second frame 190 and is formed to surround the outer circumference of the rotation axis 200.

As shown in Figs. 7 and 8, the pipe 220 is formed into a hollow cylindrical shape. A thread is formed on the outer circumferential surface of the one end 221 of the pipe 220 and inserted into the step 142 of the hollow tube 141 to be screwed.

A protrusion 222 is formed on an outer circumferential surface adjacent to the one end 221 of the pipe 220. The protrusion 222 is formed in a ring shape along the outer periphery of the pipe 220.

7, one end 221 of the pipe 220 is inserted into the hollow tube 141, and one side of the protrusion 222 is in contact with the end of the hollow tube 141, So that it is prevented from being further inserted into the hollow tube 141.

The other end of the pipe 220 is formed adjacent to the agitator main body 100 rather than the impeller 202. In other words, the other end of the pipe 220 may not be formed to extend adjacent to the impeller 202, but may be formed to be short in length to be adjacent to the first frame body 182. Since the pipe 220 is firmly coupled to the connection part 140, the rotation shaft 200 can be stably supported even if the pipe 220 is short.

Accordingly, the length of the outer tube 210 outside the pipe 220 can be shortened, so that the amount of the stirring material remaining in the outer tube 210 can be reduced, and the amount of the leakage of the agitator main body 100 can be reduced.

A bearing 240 is disposed at a position adjacent to the opposite end of the pipe 221 at one end 221, that is, at the other end. The bearing 240 is formed in a hollow cylindrical shape. The bearing 240 is preferably a sliding bearing.

The bearing 240 is disposed between the inner circumference of the pipe 220 and the outer circumference of the sleeve 230 to rotatably support the rotation axis 200.

As described above, since the one end 221 of the pipe 220 is screwed to the hollow tube 141 of the main body 100 of the stirrer so that the coupling is firm and stable, It is possible to stably support the radial load of the rotating shaft 200 and to effectively prevent the rotation shaft 200 from being warped and to improve the strength.

The sleeve 230 is formed in a cylindrical shape and is disposed between the bearing 240 and the outer periphery of the rotation shaft 200 and is coupled to the rotation shaft 200. Wear of the rotating shaft 200 can be prevented through the sleeve 230.

Both ends of the sleeve 230 are formed adjacent to both ends of the pipe 220. A portion of the sleeve 230 adjacent to the one end 221 of the pipe 220 is coupled to the rotating shaft 200 with a pin. Therefore, when the connecting portion 140 is separated from the second frame 190, the sleeve 230 can be easily separated from the rotating shaft 200 and replaced.

On the other hand, an outer cylinder 210 is disposed on the outer periphery of the pipe 220.

One end of the outer tube 210 is inserted into the stirring tank 300 through the vicinity of the central portion of the first frame body 182 and the other end is inserted into the center portion of the second frame body 192, The stepped portion 215 is formed so as to abut the projecting portion 222 of the pipe 220.

The outer cylinder 210 is formed in a hollow cylindrical shape and surrounds the outer periphery of the pipe 220 and is disposed inside and through the first frame body 182 and the second frame body 192.

A spherical portion 214 is formed on the outer periphery of the outer cylinder 210 so as to protrude outward. So that it contacts the inside of the cylindrical portion 184 of the first frame 181.

The other end of the outer cylinder 210 inserted into the second frame body 192, that is, the inner diameter of the step 215, is formed to be larger than the outer diameter of the projection 222. The outer cylinder 210 inserted into the stirring tank 300 has a stepped portion 212 formed in a cylindrical shape at one end thereof.

The outer diameter of the step portion 212 is smaller than the outer diameter of the pipe 220. The inner diameter of the stepped portion 212 is formed to be larger than the outer diameter of the rotating shaft 200.

The inner diameter of the stepped portion 212 is formed to be larger than the outer diameter of the rotary shaft 200 so that the agitated material such as oil can flow into the space between the inner peripheral surface of the stepped portion 212 and the outer peripheral surface of the rotary shaft 200.

A lid 250 is disposed between the stepped portion 212 and the impeller 202 at one end of the outer cylinder 210 to be coupled to the outer periphery of the rotary shaft 200. The lid 250 is positioned adjacent to the step portion 212 of the impeller 202 and spaced apart from one end of the outer tube 210, that is, the step portion 212.

An inner circumferential surface of the lid 250 is in contact with the outer circumferential surface of the rotary shaft 200 and a part of the inner circumferential surface of the inner circumferential surface of the lid 250 is radially stepped, .

6, the lid 250 is disposed apart from the step portion 212 of the outer cylinder 210 in a state where the stirrer is assembled.

9, when the connecting portion 140 of the main body 100 of the stirrer 100 is separated from the frame 180 and the rotating shaft 200 is moved in the axial direction with respect to the outer tube 210 when the stirrer main body 100 is disassembled, The lid 250 moves in the axial direction together with the rotating shaft 200. [ The step portion 212 is inserted into the insertion space 252 of the lid 250 so that one end of the outer cylinder 210 is closed. That is, the lid 250 can open and close one end of the outer cylinder 210 as the rotary shaft 200 moves in the axial direction.

The lid 250 closes one end of the outer cylinder 210 when the agitator main body 100 is disassembled to prevent the agitation water in the agitation tank 300 from flowing into the outer cylinder 210, Maintenance work of the agitator is easy.
