At the same time, the cleaning plate 8495 on the slide plate 8494 can clean and scrape the inner wall of the bulk barrel 846, so as to avoid the accumulation of polyethylene raw materials on the inner wall of the bulk barrel 846. At the same time, the arc plate 8497 follows the cleaning barrel 8491 to rotate, and the arc plate 8497 rotates in the inner cavity of the rotating groove 8496, so that the arc plate 8497 can clean and scrape the dusty polyethylene raw materials adhering to the bulk barrel 846.

[0022] The specific workflow is as follows: During operation, the polyethylene raw material is put into the tank body 1 through the feed port 3, and the first motor 4 is turned on to rotate forward, so that the first motor 4 drives the stirring component 7 to stir the polyethylene raw material in the tank body 1. When the stirring of the polyethylene raw material is completed, the discharge component 8 is opened to discharge the polyethylene raw material.

At the same time, by providing the rubber plate 77, it is avoided that the inner wall of the tank body 1 is damaged by long-term contact and scraping with the inner wall of the tank body 1. At the same time, when the stirring shaft 71 rotates, the contact mechanism 79 is driven to move on the bottom plate 6, so that the contact mechanism 79 disperses the polyethylene raw material accumulated on the bottom plate 6, thereby avoiding the accumulation of polyethylene raw materials during stirring, thereby increasing the stirring time; When the first motor 4 rotates forward, the contact rod 791 is driven to rotate in the inner cavity of the tank body 1 through the stirring shaft 71, so that the connecting rod 792 drives the guide rod 793 and the guide ball 794 to rotate on the top of the bottom plate 6, so that the guide ball 794 and the guide rod 793 can extrude and disperse the polyethylene raw material accumulated on the top of the bottom plate 6 during the stirring operation, thereby avoiding the phenomenon of the polyethylene raw material agglomerating during the stirring, thereby reducing the stirring efficiency of the polyethylene raw material; When the first motor 4 rotates forward, the connecting rod 792 drives the scraper 76 to squeeze the limit plate 783, and the limit plate 783 moves toward the limit groove 781 under the squeezing force. When the first motor 4 rotates reversely, the connecting rod 792 drives the scraper 76 to abut against the limit plate 783, so that the limit plate 783 blocks the scraper 76. When the first motor 4 rotates reversely, the scraper 76 scrapes the top of the bottom plate 6, thereby scraping off the polyethylene raw material impurities on the bottom plate 6, and avoiding excess impurities remaining on the top of the bottom plate 6 when the polyethylene raw material is stirred. After the polyethylene raw material in the tank body 1 is stirred, the valve stem 82 is rotated so that the valve stem 82 drives the valve plate 83 to turn over in the inner cavity of the discharge barrel 81, so that the polyethylene raw material after the stirring process is discharged through the discharge barrel 81; After the stirred polyethylene raw material is discharged, the rotating plate 842 is rotated so that the rotating plate 842 drives the bulk barrel 846 to abut against the bottom of the discharge barrel 81, and the second motor 848 is turned on at the same time. The output end of the second motor 848 drives the guide shaft 8410 to rotate in the inner cavity of the discharge barrel 81, so that the guide shaft 8410 drives the bulk plate 8411 to rotate in the inner cavity of the bulk barrel 846, so as to diffuse the polyethylene raw material passing through the bulk barrel 846, thereby avoiding the blockage of the polyethylene raw material after stirring when discharging. When the guide shaft 8410 rotates, it also drives the cleaning The component 849 rotates in the inner cavity of the bulk barrel 846, so that the cleaning component 849 cleans the inner wall of the bulk barrel 846. After the polyethylene raw material in the tank body 1 is discharged, the rotating plate 842 is rotated so that the rotating plate 842 drives the collecting barrel 843 to abut against the bottom of the discharging barrel 81. When the first motor 4 reverses to clean the inner wall of the tank body 1, the suction machine 844 is turned on, and the suction force generated by the suction machine 844 adsorbs the impurities cleaned and dropped from the tank body 1 onto the filter plate 845, thereby preventing the impurities from remaining in the tank body 1 and being unable to be discharged after the inner wall of the tank body 1 is cleaned. When the output end of the second motor 848 drives the connecting block 8412 to rotate in the inner cavity of the bulk barrel 846 through the guide shaft 8410, the slide plate 8494 is separated from the slide groove 8492 by the action of centrifugal force, so that the knocking block 8498 collides with the inner wall of the bulk barrel 846. The vibration generated when the knocking block 8498 collides with the inner wall of the bulk barrel 846 can shake off the polyethylene raw material adhering to the inner wall of the bulk barrel 846 during discharging. At the same time, the cleaning plate 8495 on the slide plate 8494 can clean and scratch the inner wall of the bulk barrel 846, thereby preventing the polyethylene raw material from accumulating on the inner wall of the bulk barrel 846. At the same time, the arc plate 8497 follows the cleaning barrel 8491 to rotate, and the arc plate 8497 rotates in the inner cavity of the rotating groove 8496, so that the arc plate 8497 can clean and scratch the dusty polyethylene raw material adhering to the bulk barrel 846.
