Description

Technical Field

[0002] Existing feed screening devices for feed processing all screen different types of feed raw materials before mixing them to make the particles of the same size for easy mixing. Although the screened feed raw materials can make the particles of the same size for easy mixing and processing, they do not screen out large impurities such as mud blocks and straw remaining in the raw materials well, and the feed raw materials with larger particles screened out are not processed for utilization. For example, a feed screening device disclosed in a Chinese patent, whose application number is CN202322663501.5, although the feed is screened and its larger particles are moved to the inside of the conveying opening at an inclined angle and fall into the inside of the stabilization box, and then the secondary screening of the feed is achieved, further improving the screening efficiency of the feed, but the screened large-particle feed is not processed, resulting in waste of resources and screening efficiency. At the same time, impurities such as mud blocks that may remain in the feed raw materials are not processed, or the impurities are directly sent to the stabilization box together with the large-particle feed to wait for processing, which increases the workload and has limitations in use.
