[0015] The present invention adopts the above technical solution, which can bring the following beneficial effects: 1. The transmission device for pig feed production uses a screening mechanism to receive feed using a feed hopper, and then drops it into a crushing box for crushing and separation. Feed that meets the standards is scattered into the screening box for screening. The feed is graded through multiple screening plates, and the feed falls into different guide pipes in turn and flows out onto a conveyor belt for classified transmission. At the same time, unqualified feed falls along a discharge plate for recycling and secondary processing. At the same time, when not working, the screening plate is disassembled and inspected using an inspection door, and the feed residue attached to it is cleaned to prevent residues from contaminating the next separation of new feed.

[0016] 2. The transmission device for pig feed production, through the screening mechanism set up, uses the second motor installed on the bracket to drive the transmission rod on the right to rotate, thereby driving the conveyor belt to work, and at the same time drives the transmission rod on the left to rotate, which will drive the elliptical block to rotate, and push the contacting movable rod through its outer wall originally far away from the center of the circle, so that the movable sleeve moves up on the outer wall of the fixed rod. When the outer wall of the elliptical block close to the center of the circle contacts the movable rod, under the action of gravity, the movable sleeve moves down on the outer wall of the fixed rod, thereby making the outer walls of the screening box and the movable sleeve fixed rod move up and down, achieving a shaking effect, thereby promoting the screening of feed by the screening plate, avoiding the accumulation of feed on the screening plate and the feed guide pipe, affecting the feed screening.

[0017] 3. The transmission device for pig feed production, through the scraping mechanism, utilizes the rotating sleeve on the outer wall of the movable shaft installed on the inner wall of the screening box, and cooperates with the scraper connected to its outer wall to contact the outer wall of the conveyor belt. Then, when the conveyor belt rotates to feed, it can scrape off the feed and impurities attached to the outer wall of the conveyor belt to avoid attachment to the outer wall of the conveyor belt, prevent affecting the next screening and achieve the purpose of self-cleaning.

[0018] 4. The transmission device for pig feed production has a scraping mechanism. When the screening box moves up and down, the coil spring is used to push the rotating sleeve to deflect upward around the movable axis. When the screening box moves downward, the scraper is squeezed to move downward, thereby generating a relative movement along the conveyor belt, thereby achieving the purpose of assisting in scraping off impurities and feed attached to the surface of the conveyor belt, thereby achieving a better scraping effect. At the same time, when the screening box moves upward, the coil spring is used to push the rotating sleeve to deflect upward around the movable axis, and push the scraper to fit tightly against the conveyor belt, thereby achieving scraping of the conveyor belt.

[0019] 5. The transmission device for pig feed production has a crushing mechanism. When the feed enters the crushing box, the crushing rods 1 and 2 are staggered and rotated relative to each other by the rotating shaft 1 and the rotating shaft 2, thereby driving the crushing rods 1 and 2 to rotate relative to each other. This can not only crush the agglomerated feed, but also produce a mutual squeezing effect when the crushing rods 1 and 2 intersect, thereby achieving the purpose of squeezing and crushing the agglomerated feed, and further improving the crushing effect.

[0020] 6. The transmission device for pig feed production, through the crushing mechanism, uses the roller brush arranged on the outer wall of the second crushing rod, and uses the rotating crushing rod to drive the roller brush to rotate on the separation plate, so as to clean the feed and impurities attached to the top thereof, thereby avoiding the feed and impurities from adhering to the separation plate and affecting the feed quality during the next separation, and at the same time avoiding clogging of the separation plate, and the bottom of the crushing rod 1 will move the roller brush after contacting the roller brush, thereby peeling off the feed and impurities attached to the roller brush, thereby achieving the effect of self-cleaning.

[0021] 7. The transmission device for pig feed production, through the crushing mechanism, after a plurality of spherical push rods installed at the bottom of the rotating mounting sleeve contact the hemispherical block, will squeeze downward and push the separation plate to move downward to squeeze the compression spring, so that in the process of the separation plate moving downward, the bristles on the brush plate will penetrate into the gaps on the separation plate to clean the gaps in the separation plate, further improving the cleaning effect; at the same time, after the spherical push rod is separated from the hemispherical block, it will contact the separation plate, and the compression spring will no longer receive downward pressure, thereby pushing the separation plate upward, and pushing the separation plate upward, thereby causing the separation plate to shake up and down, further promoting the vibration of the feed on the separation plate, promoting its separation and falling into the screening box for screening.
