[0006] According to the above technical solution, a telescopic elastic rod is fixedly installed on the surface of the fixed box, the free end of the telescopic elastic rod is fixedly connected to the plug plate, and the sliding plate slides through the top of the feed bin.

[0009] According to the above technical solution, the drying cylinder is connected to the threaded rod by threads, a conveyor belt is connected between the threaded rod and the mixing cylinder, and dry particles are arranged inside the drying cylinder.

[0013] The present invention provides a livestock feed screening and refining device, which has the following beneficial effects: (1) The livestock feed screening and refining device drives the tamping rod to move downward by the sliding plate moving downward, and at the same time, the tamping rod moves downward to drive the tamping hammer to move. The movement of the tamping hammer crushes the livestock feed accumulated in the refining trough through the tamping hammer. Through the crushing and refining process, the size consistency of the particles in the feed can be ensured, and the nutritional imbalance caused by too large or too small particles can be avoided. The refined feed is easier to be digested by animals, which can improve the feed conversion rate. When the tamping hammer moves upward under the action of the tamping rod, the plug plate also moves downward under the action of the deformation recovery of the telescopic elastic rod to release the limit on the filter hole at the bottom of the refining trough, thereby avoiding that the tamping hammer squeezes the crushed livestock feed through the filter hole at the bottom of the refining trough during operation to form large pieces of livestock feed residue, thereby affecting the subsequent screening process.

[0014] (2) The livestock feed screening and refining device drives the threaded rod to rotate through the rotation of the gear. Since the drying cylinder and the threaded rod are connected by threads, the rotation of the threaded rod drives the drying cylinder to move back and forth to dry the livestock feed inside the machine body. The feed after drying is usually drier and looser, which helps to improve the fluidity of the feed in the subsequent screening process and avoids the livestock feed from sticking together when it is wet. At the same time, the rotation of the threaded rod drives the mixing drum to rotate. The rotation of the mixing drum performs secondary grinding of the livestock feed inside the machine body through the blades installed on the surface. The feed particles after grinding are usually finer and more uniform, reducing the agglomeration phenomenon, thereby making the subsequent processing smoother. In particular, in the granulation process, the fine and uniform feed powder can ensure that the granules are more compact and have higher strength after being made.

[0015] (3) The livestock feed screening and refining device contacts and pushes the sieve plate 1 upward by the movement of the top plate. Then, when the sieve plate 1 loses the effect of the top plate on it, the deformation of the telescopic elastic rod 2 is restored to drive the sieve plate 1 to move upward. At this time, the vibration effect of the sieve plate 1 and the sieve plate 2 is achieved. The vibration helps the livestock feed particles to flow on the sieve plate, so that the particles pass through the sieve plate more evenly, avoiding the agglomeration and uneven distribution of the livestock feed particles. At the same time, the cleaning plate 1 moves in the direction close to the spring under the action of the inclined block. At the same time, the movement of the cleaning plate 1 drives the cleaning plate 2 to move through the telescopic column, thereby achieving the cleaning effect of the surface of the sieve plate 1 and the sieve plate 2, avoiding the sieve holes on the surface of the sieve plate 1 and the sieve plate 2 being blocked by livestock feed during long-term operation, thereby affecting the effect and quality of screening livestock feed.
