[0030] The bottom end of the mixing cylinder 1 is provided with a sealing and discharge mechanism 5, which includes a discharge pipe 501, a sealing ring 502, a fixing block 503, a pin 504, a protrusion 505, a top plate 506, a sealing plate 507, and a rubber pad 508.
[0031] A discharge pipe 501 is snapped into the middle of the bottom of the mixing cylinder 1, and a sealing ring 502 is snapped into the top of the inner wall of the discharge pipe 501. Fixing blocks 503 are symmetrically snapped into the bottom of the outer side of the discharge pipe 501. Pins 504 are threaded into the two fixing blocks 503.

[0032] A limiting block 6 is engaged with the inner wall of the mixing cylinder 1 at the position corresponding to the outer side of the traction cross rod 406, and a collar 7 is fixedly sleeved at the top position of the limiting block 6 on the outer side of the traction cross rod 406.

[0033] The working principle and usage process of this utility model are as follows: First, the stirring motor 3 drives the cross drum 413, the limiting cross rod 412, the vertical rod 410 and the stirring blade 411 to rotate, which stirs the raw materials inside the mixing drum 1 and improves the mixing effect. At the same time, the rotating motor 402 drives the swing plate 403 to rotate, and through the cooperation of the rotating plate 404 and the connecting block 405, the traction cross rod 406 slides up and down inside the cross sleeve 407. Then, through the cooperation of the connecting plate 408, the floating plate 409 swings up and down at the bottom of the mixing drum 1, thereby stirring up the raw materials that have settled at the bottom of the mixing drum 1 and reducing the amount of raw materials settling at the bottom of the mixing drum 1. Furthermore, the rising floating plate 409 carries the vertical rod 410, the stirring blade 411 and the limiting cross rod 412 to slide up and down along the inside of the cross drum 413, changing the position of the stirring blade 411 and further improving the mixing effect.
[0034] Next, the limit block 6 limits the traction cross rod 406 during its up-and-down sliding process, preventing the traction cross rod 406 from deviating and ensuring stability. Furthermore, by utilizing the extension and retraction characteristics of the tension spring 9, the collar 7 pushes the traction cross rod 406 back to its original position when it descends and resets, thus improving the reset efficiency.
[0035] Finally, by rotating the pin 504, it moves along the inside of the fixed block 503, facilitating the upward movement of the protrusion 505, top plate 506, and sealing plate 507. This ensures that the sealing plate 507 fits tightly against the sealing ring 502, guaranteeing a sealing effect and preventing leakage. Simultaneously, the rubber gasket 508 fills the inside of the sealing ring 502, further improving the sealing effect and preventing raw materials from settling and accumulating inside the sealing ring 502, thus ensuring a good mixing effect. In addition, reversing the pin 504 facilitates the removal of the protrusion 505, top plate 506, sealing plate 507, and rubber gasket 508 from the discharge pipe 501, making material discharge easier.
[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
