Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-2 As shown, a discharge device includes a base 3 and a discharge rod 6 that can move up and down inside the base 3; a drive assembly is connected to the lower inclined surface of the base 3, and the output end of the drive assembly is connected to the lower outer wall of the discharge rod 6 for driving the discharge rod 6 to move up and down; a cover plate 1 is connected to the upper end of the discharge rod 6, and the cover plate 1 is used to block the feed port of the base 3; wherein, the drive assembly drives the discharge rod 6 to move up and down to realize the opening and closing of material discharge.

[0026] Specifically, the drive assembly includes two support members 401 and two drivers 4; the two support members 401 are respectively connected to two inclined surfaces at the lower end of the base 3, and the fixed end of one driver 4 is connected to each of the two support members 401. The output ends of the two drivers 4 are respectively connected to the two ends of the drive seat 5, and the lower side wall of the discharge rod 6 is sleeved in the middle of the drive seat 5.

[0027] Specifically, a second channel 602 is provided on the lower end of the discharge rod 6, and a first channel 601 is provided on the side wall of the discharge rod 6, which is connected to the second channel 602; the first channel 601 is connected to the feed inlet of the base 3.

[0028] Specifically, the base 3 is connected to the positioning members 10 on both sides by fasteners 301. A sealing member 309 is provided between the base 3 and the positioning members 10. The fasteners 301 can be bolts; the positioning members 10 and the base 3 can also be connected by welding.

[0029] Specifically, a sealing element 2 is connected to the lower end face of the cover plate 1 for sealing with the feed inlet of the base 3. The cover plate 1 is inverted conical in shape. The cover plate 1 can also be flat.

[0030] Specifically, the contact surface between the discharge rod 6 and the base 3 is sealed by the sealing element 8, and linear movement is achieved by the guide element 7.

This solves the problem of uneven material mixing and dead zones in powder circulation mixing equipment, improving product quality. Furthermore, it has a simple structure, making it easy to install and fix.
