[0040] A hammer mill for processing fish feed includes: a motor 100, a feeding section 200, and a crushing section 300;

[0041] The pulverizing section 300 includes a housing 310, a fixed shaft 320, a hammer assembly 330, a support member 340, and a screen 350. The fixed shaft 320 is fixed to the bottom of the pulverizing section 300. The housing 310 is rotatably mounted on the fixed shaft 320 and can be opened and closed around the fixed shaft 320. The hammer assembly 330 is rotatably mounted inside the pulverizing section 300. The screen 350 is fixedly mounted on both sides of the hammer assembly 330. The support member 340 is detachably mounted on the outside of the screen 350. A vertical plate 342 is horizontally arranged at the bottom inner side of the pulverizing section 300. A lifting plate 360 ​​is provided between the two parts. A sliding rod 370 is vertically fixed at the bottom of the lifting plate 360. A translation plate 392 is closely attached to the bottom of the sliding rod 370. A fixing block 380 is fixedly provided on the upper surface of the translation plate 392. An inclined surface 384 is provided on the fixing block 380. The sliding rod 370 can slide along the inclined surface 384 to the top of the fixing block 380 when the translation plate 392 moves horizontally. The motor 100 is fixedly provided on the side of the crushing part 300. The hammer assembly 330 can rotate under the drive of the motor 100. The feeding part 200 is fixedly provided on the top of the crushing part 300.

[0042] When crushing is required, fish feed is fed from the feeding section. Upon reaching the crushing section, it is broken by the hammer mill assembly. Feed particles that meet the size standard fall through the screen. Uncrushed feed or feed that still does not meet the size standard after crushing falls to the bottom of the crushing section. At this point, moving the horizontal sliding plate raises the lifting plate. Once raised, the fish feed at the bottom is pushed back to the hammer mill assembly for further crushing. The lifting plate is positioned between vertical plates to prevent horizontal movement, and the sliding rod passes through holes in the bottom plate of the crushing section, ensuring that it moves only in the vertical direction.

[0043] In a preferred embodiment of this invention, the support member 340 is rotatably mounted at the end of the vertical plate 342 via a hinge 341. The support member is used to ensure the stability of the screen and prevent deformation. By allowing the support member to rotate around an axis, it can both support the screen and facilitate its opening for routine cleaning.

[0044] In a preferred embodiment of this utility model, a rack 390 is fixedly mounted on the bottom of the translation plate 392, and a gear 391 is rotatably mounted below the rack 390. The rack 390 and the gear 391 mesh, and a rotating shaft 393 is fixedly mounted on the gear 391. The rotating shaft 393 extends to the outside of the crushing section 300. Rotating the rotating shaft 393 can drive the gear 391 to rotate. The bottom of the slide rod 370 is provided with an inclined plane 371 with the same inclination angle as the inclined plane 384. The inclined plane 371 can slide along the inclined plane 384. The gear and rack working together enable the rack to drive the translation plate to move horizontally when the gear rotates. The rotating shaft extending to the outside allows for easy manual rotation of the gear when feed accumulates at the bottom, causing the slide rod to slide up along the inclined plane. When the lifting plate rises to the hinge, a slight impact is generated. The vibration generated by the impact can be transmitted to the screen, shaking off the feed residue stuck on the screen for subsequent crushing.

[0045] In a preferred embodiment of this invention, the bottom of the slide rod 370 is further provided with a second inclined surface 372, and the top of the fixing block 380 is provided with a groove 381. One side of the groove 381 is provided with a third inclined surface 382 at the same angle as the second inclined surface 372, and the other side is provided with a vertical surface 383. The second inclined surface 372 can slide along the third inclined surface 382, ​​while the first inclined surface 371 cannot slide along the vertical surface 383. The groove and the vertical surface allow the slide rod to be stopped after sliding to the top of the fixing block, ensuring that the lifting plate can be stably maintained at its highest point to support the feed. The second and third inclined surfaces ensure that the slide rod can slide out of the groove again and then slide along the fourth inclined surface to the bottom.

[0046] In a preferred embodiment of this utility model, a handle 394 is fixedly provided at the end of the rotating shaft 393. The handle facilitates manual rotation of the rotating shaft.

[0047] In a preferred embodiment of this utility model, the feeding unit 200 comprises a variable speed motor 210 and a feeding box 220.

A rotating wheel 223 is rotatably mounted in the feeding channel 222, and the rotating wheel 223 can rotate under the control of the variable speed motor 210. The feeding channel is horizontal to prevent material from flying out of the feeding port during bottom crushing operations. The rotation speed of the rotating wheel is controlled by the variable speed motor, which can increase the rotation speed when a larger feeding amount is needed, allowing more material to be pushed down and fed in per unit time.

[0048] In a preferred embodiment of this invention, a latch 311 is provided on the side of the outer casing 310, which locks the outer casing 310 when the latch 311 is tightened. The latch ensures the outer casing is locked, maintaining airtightness and preventing material leakage during the crushing process.

[0049] As a preferred embodiment of this utility model, a handle 312 is fixedly provided on the surface of the outer shell 310. The handle facilitates the opening and closing of the outer shell.
