Screening device for straw and forage type animal husbandry feed

Abstract

The invention provides a straw and forage type livestock feed screening device, and belongs to the technical field of feed screening, the straw and forage type livestock feed screening device comprises a processing table, a screening groove is formed in the processing table, an auxiliary screening plate is slidably inserted in the bottom wall of the screening groove, a fixed seat corresponding to the screening groove is arranged on the processing table, and a movable block is slidably connected to the fixed seat; inserting rod sets are symmetrically and rotationally connected to the movable block, each inserting rod set comprises a plurality of round rods, gear seats are connected to the round rods, gear control assemblies are connected between the gear seats and the fixed seat, and separating rods are evenly and rotationally embedded into the round rods. According to the straw and forage type livestock feed screening device, the problem that the soil particle screening effect is reduced due to the fact that straw is prone to huddling and gathering can be effectively solved, the straw and forage screening and impurity removing effect is correspondingly improved, meanwhile, straw inserted in screening holes in a penetrating mode can be treated, and the screening efficiency is improved. The problem that the screening effect is reduced due to the fact that the straw penetrates through the screening holes to prevent sludge from being discharged is effectively solved.

Description

technical field [0001] The invention relates to the technical field of feed screening, in particular to a screening device for straw and forage animal husbandry feed. Background technique [0002] Straw forage is a multi-purpose renewable biological resource. It not only has high crude fiber content, but also contains rich trace elements and organic matter. It can be used directly as livestock feed or put into use after processing. Whether it is used or processed, it is necessary to sieve and remove impurities from the forage livestock feed to improve the purity of the feed, especially the soil in the forage, because the forage will carry a large amount of dust when it is collected. Soil seriously affects the taste of forage, reduces the appetite of livestock and poultry, and affects the growth of livestock and poultry. [0003] At present, the effect of screening and removing impurities from straw forage livestock feed is poor, because the straw is easy to clumped together...

Problems solved by technology

[0002] Straw forage is a multi-purpose renewable biological resource. It not only has high crude fiber content, but also contains rich trace elements and organic matter. It can be used directly as livestock feed or put into use after processing. Whether it is used or processed, it is necessary to sieve and remove impurities from the forage livestock feed to improve the purity of the feed, especially the soil in the forage, because the forage will carry a large amount of dust when it is collected. Soil seriously affects the taste of forage, reduces the appetite of livestock and poultry, and affects the growth of livestock and poultry

[0003] At present, the effect of screening and removing impurities from straw forage livestock feed is poor, because the straw is easy to clumped together, and during the screening process, the soil is mixed in the gathered straw and cannot be screened out. Secondly, in the screening process , the straw is easy to be inserted in the screening hole so that the sludge cannot be discharged and the screening effect is reduced
