[0002] Premix feed refers to a mixture of one or more additive raw materials and a carrier or diluent that is evenly stirred, which is conducive to the uniform dispersion of trace amounts of raw materials in a large amount of compound feed before transportation and addition. Existing premix feed conveying equipment, such as a composite premix feed conveying equipment for livestock and poultry disclosed in application number CN201920188870.4, solves the problem of impurities such as stones and soil mixed in the raw materials, which causes indigestion after ingestion by livestock and poultry through the design of a screening device, and the raw materials are double-screened by the primary filter and the secondary filter, thereby achieving the beneficial effect of quickly and conveniently separating the impurities mixed in the raw materials.

[0003] However, in actual use, since the amount of feed is usually large, the screening device used in the prior art, as the use time increases, although the larger feed particles and foreign matter are filtered out, they cannot be discharged in time, resulting in more and more larger impurities above the filter, which will affect the efficiency and effect of subsequent feed screening, and the filtered feed is directly discharged after falling into the feed hopper, and it is difficult to effectively mix different feeds, resulting in unsatisfactory premixing effect. For this reason, we propose a livestock and poultry composite premix feed conveying equipment to solve the above problems. Utility Model Content
