Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0022] like Figures 1-4 The dust removal device for a feed grinder shown includes a mounting frame 1, a centrifugal fan 2, and a protective mechanism 3. The centrifugal fan 2 is mounted on the top of the mounting frame 1, and the protective mechanism 3 is located at the air inlet of the centrifugal fan 2. The protective mechanism 3 includes a mounting cover 31, a guide ring 32, an isolation mesh cover 33, a connecting shaft 34, a support frame 35, a scraper 36, a first pulley 37, a motor 38, a second pulley 39, a belt 310, and a baffle plate 311. The mounting cover 31 is mounted on the outside of the air inlet of the centrifugal fan 2, and the guide ring 32 is fixedly mounted on the mounting cover 3. 1. On one end of the inner side, the isolation net cover 33 is clamped in the guide ring 32, the connecting shaft 34 is fixedly set on the outer side of one end of the isolation net cover 33, the support frame 35 is fixed to the inner side of one end of the mounting cover 31, the scraper 36 is fixedly connected to the support frame 35, the first pulley 37 is fixedly set on the end of the connecting shaft 34, the motor 38 is installed on the inner side of the mounting cover 31, the second pulley 39 is sleeved on the output end of the motor 38, the belt 310 is sleeved on the outside of the first pulley 37 and the second pulley 39, and the wind baffle 311 is fixedly set on the inner side of the bottom of one end of the mounting cover 31.

[0023] Specifically, the mounting cover 31 has dust suction holes on its surface and a material discharge hole at its bottom. The connection between the wind baffle 311 on one side of the mounting cover 31 and the mounting cover 31 is located on the outside of one side of the guide ring 32. The isolation net cover 33 has a frustum-shaped structure with material blocking holes on its surface. The wind baffle 311 is located on the inside of the bottom of the isolation net cover 33. The connecting shaft 34 is movably connected to the support frame 35, with one end passing through and extending to the outside of one end of the support frame 35. The bottom of one side of the scraper 36 is in contact with the surface of the isolation net cover 33. A retaining ring is fixedly provided on the outside of one end of the isolation net cover 33, and the retaining ring on the outside of one end of the isolation net cover 33 is engaged in the guide ring 32.

[0024] In this embodiment, the mounting bracket 1 of the dust removal device is connected to the outside of the feed grinder, and the protective mechanism 3 extends into the inside of the feed grinder. The air inlet of the centrifugal fan 2 is connected to the dust discharge hole of the feed grinder. When the feed grinder starts working, the internal crushing device crushes and grinds the feed raw materials, resulting in a large amount of dust inside. At this time, the centrifugal fan 2 is started. Under the high-speed operation of the centrifugal fan 2, a negative pressure is generated inside the feed grinder, so that the dust is sucked in by the centrifugal fan 2 and discharged, reducing the amount of dust inside and ensuring the quality of the crushed feed.

[0025] Furthermore, when the centrifugal fan 2 rotates at high speed, lightweight feed fragments such as crushed grass leaves in the feed raw materials will be adsorbed onto the surface of the isolation net cover 33, causing the isolation net cover 33 to become clogged and affecting the dust collection effect. At this time, the motor 38 starts, and through the second pulley 39 at its end and the belt 310, it controls the rotation of the first pulley 37 at the end of the connecting shaft 34, thereby causing the isolation net cover 33, which is stuck in the guide ring 32 at one end, to rotate slowly. The isolation net cover 33 has a frustum-shaped structure, which ensures the dust collection area while providing space for the installation of the motor 38. The connecting shaft 34 at the end of the isolation net cover 33 and the support frame 3 5. The movable connection improves operational stability. The surface of the mounting cover 31 is provided with dust suction holes to avoid obstructing the suction of dust. The isolation net cover 33 rotates, causing the scraper 36 fixed on the support frame 35 to scrape off the grass and other debris adsorbed on the surface of the isolation net cover 33. The wind baffle 311 on the inner side of the bottom of the mounting cover 31 greatly reduces the suction force at the bottom of the isolation net cover 33, thereby quickly reducing the suction force on the debris scraped by the scraper 36, causing the debris to fall off. The material drop hole at the bottom of the mounting cover 31 avoids obstructing the falling debris, thus achieving the function of cleaning the isolation net cover 33 and ensuring the dust suction effect.
