When the slider 24 rises to the top in the column 26, the stirring barrel 20 can be placed below the stirring shaft 13 and other components at this time. The motor 27 is a servo motor, and the slider 24 can be lowered by adjusting the rotating direction of the motor 27, so that the stirring shaft 13 and the scraper assembly 16 can extend into the interior of the stirring barrel 20. At this time, the barrel cover 22 covers the top of the stirring barrel 20 to prevent the raw materials in the stirring barrel 20 from splashing out during subsequent stirring. The arc-shaped clamping plate 30 is moved towards the stirring barrel 20 by starting the air cylinder 29, so that the two arc-shaped clamping plates 30 can clamp the stirring barrel 20, so that the stirring barrel 20 can be prevented from moving during subsequent stirring of the lubricating oil raw materials in the stirring barrel 20, and the overall structure is beneficial to quickly withdrawing the stirring barrel 20 after fully stirring the lubricating oil raw materials.
