Technical Field

[0001] This utility model belongs to the field of screening technology, and in particular relates to an alloy powder sieve. Background Technology

[0002] After the alloy powder is processed, it is generally necessary to screen and sieve it to remove large particles and ensure the fineness of the resulting alloy powder.

[0003] In the actual implementation of the alloy powder screening device, it was found that there are areas for improvement: during the screening process, a certain amount of alloy powder easily adheres to the screen, which can easily cause screen blockage. Utility Model Content

[0004] In view of the shortcomings and defects in the existing technology, the purpose of this utility model is to provide an alloy powder sieve, which solves the problem that alloy powder easily adheres to the screen of the existing powder screening device, thus easily causing screen blockage.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an alloy powder sieve, including a workbench, a powder sieve connected to the workbench by a spring, a vibrating motor on the powder sieve, the bottom of the powder sieve extending below the workbench, a receiving bucket below the powder sieve on the workbench, a hanging plate connected to one side of the workbench by a vertical plate, a rotating shaft rotatably connected to the hanging plate, a telescopic rod that can extend and retract vertically on the rotating shaft, a stirring blade on the telescopic rod, rubber plates on both sides of the stirring blade, the bottom of the rubber plates protruding from the bottom of the stirring blade, the upper end of the rotating shaft connected to a rotary motor that drives its rotation, a detachable screen inside the powder sieve, and two powder covers that can be joined together on the powder sieve, the two powder covers being fixed by a snap-fit ​​connection.

[0006] As a further improvement of this utility model, the powder sieve includes an upper cylindrical cylinder and a lower funnel, the cylindrical cylinder and the funnel are welded together, and the screen is set at the bottom of the cylindrical cylinder.

[0007] As a further improvement of this utility model, an annular plate is provided on the outer side of the cylindrical tube, and one end of the spring is connected to and disposed on the annular plate, while the other end is connected to and fixed on the workbench.

[0008] As a further improvement of this utility model, the telescopic rod is an electric push rod.

[0009] As a further improvement of this utility model, the stirring blade and the telescopic rod are connected by bolts.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] 1. By connecting the powder sieve to the worktable via a spring, and installing a vibrating motor on the sieve, the vibrating motor drives the sieve to vibrate during the screening of alloy powder, facilitating the feeding of the alloy powder, ensuring smooth feeding, and reducing screen clogging. Furthermore, a rotating shaft with a telescopic rod connected to its bottom, equipped with stirring blades, agitates the alloy powder as the shaft rotates, breaking it up, reducing adhesion, improving flowability, facilitating screening, and minimizing screen clogging. Additionally, adjusting the telescopic rod allows the bottom of a rubber plate to contact the screen; rotating the shaft cleans the screen, further reducing clogging. Attached Figure Description
