Description

Technical Field

[0001] The utility model relates to the technical field of nutrient feed processing equipment for lactating dairy cows, in particular to a nutrient feed mixing and processing equipment for lactating dairy cows. Background Art

[0002] The nutritional needs of dairy cows increase significantly during lactation, and the quality and composition of their feed are also very stringent. The diet should contain at least two types of roughage, 2-3 types of green and juicy feed, and 3-4 types of concentrate feed. As milk production increases, the proportion of concentrate feed also increases accordingly. An increase in the amount of concentrate feed often results in insufficient roughage intake, leading to digestive disorders, especially rumen dysfunction. Therefore, in addition to paying attention to the combination of concentrate and roughage, it is recommended to add some nutrients or non-nutrients to the feed to regulate the rumen environment and promote the growth of rumen microorganisms, such as buffers, sulfur, niacin, pantothenic acid, and vitamin B12.

[0003] Currently, poor-quality roughage, especially hay with a high water content, is soft and lacks crispness. This leads to a prolonged stagnation in feed preparation machines, often requiring more than 15 minutes. This results in over 20% of particles larger than 5 cm in the TMR. Long hay needs to be pre-cut to avoid slow cutting speeds that affect mixing uniformity. Typically, domestic hays such as oat, wheat, sheep, and rice straw are pre-cut using a hay cutter like the Black Buster before being fed into the feed preparation machine for mixing and silage. This results in uneven silage lengths, increased mixing time, and the possibility of over-mixing the roughage, resulting in insufficient effective neutral detergent fiber. If mixing time is too short, uneven mixing leads to nutritional imbalances, which also impacts the effectiveness of nutritious feeds for lactating dairy cows. Utility Model Content

[0004] The utility model provides a lactation nutrient feed mixing and processing device, which solves the problems of uneven nutrient distribution, poor feeding effect and low production efficiency of lactation cow feed mixed by traditional feed preparation machines.

The second spiral transmission shaft is coaxially arranged in the second mixing barrel and is rotatably connected to a second bearing seat arranged on the second mixing barrel.
