[0029] Specific implementation and principle:

[0030] The coolant raw material is added into the mixing barrel 2 through the feed pipe 21 at the top of the mixing barrel 2. When the coolant raw material is added, the stirring rod 32 is driven to rotate by the output shaft of the driving motor 31 of the stirring mechanism 3, and the stirring blades 1 332 and 2 342 on the stirring rod 32 stir the coolant raw material.

[0031] When it is necessary to sample the mixing effect of the coolant, the outer plug 47 on the push rod 46 is pushed inward, and the outer plug 47 drives the inner plug 44 to move in the direction of the fixed cylinder 41, and the spring on the slide bar 42 is compressed. When the inner plug 44 continues to move, it will block the discharge hole 411 on the fixed cylinder 41, and the outer plug 47 will block the feed hole 451 on the sampling cylinder 45. At the same time, the inner plug 44 squeezes the limit plate 1 483 through the bottom inclined surface 4831 of the limit plate 1 483, so that the limit plate 1 483 moves up, and the spring 2 485 is compressed. When the limit plate 1 483 is facing the annular groove 484 on the inner plug 44, the limit plate 2 487 is detached from the slot 488 on the sampling cylinder 45. At this time, the sampling cylinder 45 can be removed from the fixed cylinder 41. At the same time, under the action of the elastic force of the spring 2 485, the limit plate 1 483 is inserted into the annular groove 484 to limit the inner plug 44.

[0032] Next, the sampling cylinder 45 is transferred to the sampling station, and the outer plug 47 can enter the sampling cylinder 45 by pulling the ejector rod 46 outward, and then the coolant in the sampling cylinder 45 is poured out for testing;

[0033] Then, slightly pull the limit plate 483 upwards, then put the sampling tube 45 on the outside of the fixed tube 41 and push it in the direction of the limit plate 483, and then continue to pull the limit plate 483 upwards to make the limit plate 483 disengage from the annular groove 484 on the inner plug 44, and the spring 2 485 is compressed, and then release the limit plate 483, and under the elastic force of the spring 2 485, the limit plate 2 487 is inserted into the slot 488 on the sampling tube 45, and under the elastic force of the spring 1 422, the inner plug 44 is separated from the discharge hole 411 on the fixed tube 41, and extends into the sampling tube 45 through the feed hole 451 on the sampling tube 45, and then the coolant in the mixing barrel 2 enters the sampling tube 45.

[0034] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
