[0022] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figure 1-4 As shown, a sieving device for preparing metal powder includes a base 1, a connecting frame 2 on the outer surface of the base 1, a drive motor 3 connected to the top of the connecting frame 2, and three sieving boxes 4 on the top of the base 1. Each sieving box 4 includes a first box body 41 and a second box body 42. A connector 43 is provided on one end face of the second box body 42, and a connector slot 44 is provided on one end face of the first box body 41 corresponding to the connector 43. Movable tracks 45 are provided on the outer surfaces of the first box body 41 and the second box body 42, and two movable bars 46 are provided on the inner sidewall of the movable track 45 on the outer surface of the first box body 41.

[0024] like Figure 1-3 As shown, the drive end of the drive motor 3 is connected to a connecting shaft 31. Scrapers 32 are provided on the outer surface of the connecting shaft 31 and inside the three sieve boxes 4. It should be noted that the drive motor 3 can drive the three scrapers 32 to stir the metal powder inside the three sieve boxes 4 through the connecting shaft 31, thereby improving the sieve efficiency.

[0025] like Figure 2-4As shown, each of the two movable bars 46 has two connecting posts 47 at one end. The inner wall of the movable track 45, located at one end of the movable bar 46, is connected to two connecting springs 48. The end face of the movable track 45 on the outer surface of the first box 41 has a storage groove 49 corresponding to the sliding path of the connecting posts 47. The end face of the movable track 45 on the outer surface of the second box 42 has a mating groove 401 corresponding to the sliding path of the connecting posts 47. Guide posts 402 are provided on the upper and lower end faces of the movable track 45. Adjusting blocks 403 are connected to the outer surface of the guide posts 402. Return springs 404 are connected to the outer surface of the guide posts 402 and the end face of the adjusting blocks 403. One end of 403 is connected to a fixing ring 405.
