Description

Technical Field

[0001] The utility model relates to the technical field of poultry feed, in particular to a grain crushing device for poultry feed. Background Art

[0002] Poultry feed crushing device is a commonly used poultry feed preparation equipment. The crushing device is mainly used to crush various feeds and various roughages. The purpose of feed crushing is to increase the surface area of ​​the feed and adjust the particle size. Increasing the surface area improves the palatability and is easy to contact with the digestive juice during digestion, which is beneficial to improve the digestibility and better absorb the nutrients in the feed.

[0003] After searching, it was found that the publication number is CN215743725U, and the name is a crushing device for poultry feed processing. The application points out that an existing crushing device has certain disadvantages when in use. When the existing crushing device is in use, it takes a long time to crush the raw materials, and the crushing is not thorough enough, and multiple crushings are required, which reduces the crushing efficiency of the device and cannot meet people's needs. Through the crushing mechanism set up, the crushing mechanism can quickly crush the raw materials inside the crushing box, and through the No. 1 rotating roller, No. 2 rotating roller and crushing tool set up, the No. 1 rotating roller drives the crushing tool to perform the initial crushing inside the guide box, and the No. 2 rotating roller drives the crushing tool to perform the secondary crushing of the crushed raw materials, thereby improving the crushing efficiency of the device The rate is high and it is convenient for people to use. The whole device has a simple structure and is easy to operate, which increases the practicality of the whole crushing device. However, in the actual production process of poultry feed, there are clear requirements for the particle size of the feed. If the particle size is too small, the gastrointestinal tract of the poultry can digest it without peristalsis after eating. When eaten for a long time, the gastrointestinal function does not peristalsis for a long time, and the function is reduced, which can easily lead to indigestion in poultry. Therefore, the poultry feed is not the finer the better. The above application adopts a multi-stage crushing structure, which can easily lead to the feed that meets the particle size requirements being crushed twice to become smaller, thereby reducing the overall feed particle size, resulting in failure to meet the minimum particle size requirements of the feed. At the same time, even after several crushings, some grains will still be larger than the particle size requirements, and the application cannot be screened out in time, affecting the uniformity of the feed.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
