[0025] The utility model provides a feed raw material powder screening device, comprising:

[0026] A powder sieve bin 1, in which a detachable sieve plate 5 is clamped, and a pin shaft 3 is installed on the outer wall of the powder sieve bin 1;

[0027] The cover plate 2 is arranged on the top of the powder sieve bin 1, one end of the cover plate 2 is connected to the powder sieve bin 1 through a pin shaft 3, the top of the cover plate 2 is threadedly connected with a threaded rod 4, and the bottom end of the threaded rod 4 is fixedly connected with a first spring 7, and the bottom end of the first spring 7 is fixedly connected with a connector 8;

[0028] The cleaning brush plate 6 is arranged at the bottom of the cover plate 2, and the top end of the cleaning brush plate 6 is detachably connected to the bottom end of the connector 8.

[0029] In the specific implementation process, Figure 2As shown, the outer wall of the screen plate 5 is provided with a frame, and the bottom of the cleaning brush plate 6 is provided with a brush layer, and the diameter of the cleaning brush plate 6 is smaller than the diameter of the frame of the screen plate 5. Through its design, when the cleaning brush plate 6 is adjusted to be lowered to contact the sieve hole part in the middle of the screen plate 5, a certain interval space is left between the cleaning brush plate 6 and the powder sieve bin 1, which provides a good protection for the cleaning brush plate 6 to shake due to vibration, so that the particle blockage in the sieve hole of the screen plate 5 can be cleaned up through the shaking of the cleaning brush plate 6 and the vibration of the powder sieve bin 1.

[0030] In the specific implementation process, Figure 3 As shown, the top of the threaded rod 4 is designed as a straight-line structure. The shape and structure of the top of the threaded rod 4 is convenient for the user to operate the threaded rod 4 to rotate. The top of the cleaning brush plate 6 and the bottom of the connecting head 8 are threadedly connected. Through its design, the cleaning brush plate 6 and the threaded rod 4 can be disassembled, which is convenient for the cleaning brush plate 6 to be disassembled separately for cleaning.

[0031] In the specific implementation process, Figure 2 and Figure 4 As shown, a magnetic ring 11 is fixedly connected inside the powder sieve bin 1, and the top of the magnetic ring 11 is magnetically attracted to the frame of the screen plate 5. The screen plate 5 can be supported by the set magnetic ring 11, and the magnetic ring 11 is magnetically attracted to the screen plate 5, so that the screen plate 5 can be easily taken out directly from the powder sieve bin 1.

[0032] In the specific implementation process, Figure 2 and Figure 4 As shown, at least one groove is provided at the bottom end of the frame of the screen plate 5, and at least one limit block 10 is fixedly connected to the top end of the magnetic ring 11, which is used to be embedded in the groove to limit the screen plate 5. The limit block 10 is embedded in the groove of the frame of the screen plate 5, so that the screen plate 5 can be limited when the powder screening bin 1 vibrates, preventing the screen plate 5 from sliding and affecting the stability of the structure, thereby providing good protection for the powder screening of feed raw materials.

[0033] In the specific implementation process, Figure 4 As shown, a base 12 is installed at the bottom of the powder sieve bin 1, and a vibration motor is arranged in the base 12, a plurality of second springs 13 are arranged between the base 12 and the powder sieve bin 1, and a material guide seat 9 is fixedly connected to the bottom end of the powder sieve bin 1.

[0034] The working principle of a feed raw material powder screening device provided by the utility model is as follows: when the feed raw material is powder screened, the feed raw material is first put into the powder screening bin 1, and the cover plate 2 is rotated to close the opening of the powder screening bin 1, and then the vibration motor in the base 12 is started to drive the powder screening bin 1 to vibrate, and small particles of feed raw material pass through the screen plate 5 and fall into the material guide seat 9, and are discharged through the openings on both sides of the outer wall of the powder screening bin 1, while large particles of feed raw material are left on the screen plate 5. After the feed raw material is powder screened, the large particles of feed raw material on the screen plate 5 are cleaned. When there are particles clogged in the sieve holes of the screen plate 5, the cover plate 2 is rotated and closed, and the cleaning brush plate 6 is adjusted to descend by rotating the threaded rod 4 until it fits with the screen plate 5, and then the vibration motor in the base 12 is started to drive the powder screening bin 1 to vibrate, and at the same time, the cleaning brush plate 6 is shaken by vibration, and the screen plate 5 is continuously cleaned, and the cleaned particles fall into the material guide seat 9 and are discharged through the openings on both sides of the outer wall of the powder screening bin 1.

[0035] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
