As shown in fig. 10, the upper ends of the two first connecting rods 20 are respectively connected to the timing belt 23 through a hinge plate 22, one ends of the two hinge plates 22 are respectively hinged to the two first connecting rods 20, and the other ends of the two hinge plates 22 are hinged to the lower end of the timing belt 23.

As shown in fig. 8, a sealing strip 19 is slidably mounted in the first guide groove 16 formed in the isolation sealing plate 14; the penetrating second guide groove 17 is sealed by the sealing strip 19, so that the upper and lower parts of the isolation sealing plate 14 are in a sliding sealing state, the sealing strip 19 is of a closed structure, is clamped in the second guide groove 17 to fill the gap of the second guide groove 17, seals the second guide groove 17, and can continuously slide in the second guide groove 17.

As shown in fig. 3, the bottom of the stirring barrel 5 is provided with an installation groove 10, as shown in fig. 4 and 5, the lower end of the output shaft of the motor 6 is fixedly provided with a third rotating shaft 37, the lower end of the third rotating shaft 37 penetrates through the fixing plate 32 and the isolation sealing plate 14 and is located in the installation groove 10 at the lower side of the stirring barrel 5, the lower end of the third rotating shaft 37 is provided with a blade, and the blade is located in the installation groove 10 and is lower than the bottom of the stirring barrel 5; when the motor 6 works, the motor 6 drives the third rotating shaft 37 to rotate through the output shaft, the third rotating shaft 37 drives the blades to rotate, the blades rotate to stir lithium battery materials in the stirring barrel 5, and the stirring effect of the lithium battery materials in the stirring barrel 5 is improved.

A plurality of scraping strips arranged along the axis of the third rotating shaft 37 are uniformly arranged on the outer circumferential surface of the third rotating shaft 37 in the circumferential direction; in the process of sliding the two scraping plates 8, when the two scraping plates 8 slide through the middle position of the stirring barrel 5, the lithium battery materials on the opposite side surfaces of the two scraping plates 8 contact and rub with the third rotating shaft 37, the lithium electronic materials on the side surfaces of the two scraping plates 8 are scraped through the third rotating shaft 37, and the scraping strips are designed to improve the scraping efficiency of the third rotating shaft 37 on the lithium electronic materials on the side surfaces of the two scraping plates 8.

As shown in fig. 5, a seal ring 11 is installed between the outer circumferential surface of the isolation seal plate 14 and the inner circumferential surface of the agitator cap 3, and a rotary seal structure is provided between the third rotary shaft 37 and the isolation seal plate 14.

The specific working process is as follows: when the stirring material designed by the invention is used, firstly, the lithium battery material is put into the stirring barrel 5, then the stirring cover 3 is covered by the hydraulic rod 1, when the stirring cover 3 is covered, the gas in the stirring barrel 5 is pumped away by the vacuum pump, so that the stirring barrel 5 is in a vacuum state, then the motor 6 is controlled to work, when the motor 6 works to drive the sun gear 30 to rotate, the gear ring 27 is fixed on the stirring cover 3 to be in a static state, rotation of the sun gear 30 drives the two planet gears 28 to rotate about the axis of the sun gear 30, when the two planet gears 28 rotate, the two planet gears 28 rotate to drive the two first gears 25 to rotate through the corresponding connecting sleeves 34, the two first gears 25 rotate to drive the two second gears 33 to rotate, the two second gears 33 rotate to drive the two synchronous wheels 29 to rotate, and the two synchronous wheels 29 rotate to drive the synchronous belt 23 to slide; the synchronous belt 23 drives the two scraping plates 8 to slide through the two hinge plates 22 and the two first connecting rods 20, the scraping plates 8 circularly slide on the isolation sealing plate 14 and simultaneously rotate around the axis of the stirring barrel 5 along with the isolation sealing plate 14 through the matching of the first connecting rods 20, the second guide grooves 17, the second connecting rods 21 and the first guide grooves 16 in the sliding process of the two scraping plates 8, and the two scraping plates 8 except the positions near the circle centers are always inclined to the moving direction in the sliding and rotating processes; the two scraping plates 8 perform spiral-like action in the stirring barrel 5 to stir the lithium battery material in the stirring barrel 5; in the stirring process, after the two scrapers 8 rotate to be in contact with the wall of the stirring barrel 5, the two scrapers 8 intermittently scrape dry and unstirred lithium battery materials adhered to the wall of the barrel, and meanwhile, when the two scrapers 8 slide through the middle position of the stirring barrel 5, the lithium battery materials on the opposite side surfaces of the two scrapers 8 are in contact friction with the third rotating shaft 37, and lithium electronic materials on the side surfaces of the two scrapers 8 are scraped through the third rotating shaft 37; after the stirring is completed, the stirring lid 3 is opened by a hydraulic pipe.
