Description

Straw fodder grinder is used to pig

The technical field is as follows:

the utility model relates to a straw fodder grinder is used to pig.

The background art comprises the following steps:

in the last two years, the pig price is continuously lowered, the profit space of breeding enterprises is continuously compressed, and how to enable the breeding enterprises to benefit the space under the current breeding environment is related to the survival problem of a plurality of breeding enterprises. The addition of auxiliary materials into the complete feed is a relatively accepted method by most of the enterprises at present, but the problems of how to add the auxiliary materials and what adding proportion is are difficult to overcome. A feed nutritionist of the company discovers that the silage contains a large amount of protein and crude fiber through a plurality of experiments, the protein in the silage can replace a part of complete feed, and the crude fiber can promote gastrointestinal movement and help digestion and absorption. The silage can not only replace a part of complete feed, but also promote the better absorption of the nutrition of the complete feed, thereby achieving the purpose of reducing the cost. However, common silage such as corn straw, wheat straw, pasture and the like cannot be directly used as auxiliary materials for feeding pigs, and the common silage must be completely crushed to be mixed into liquid feed for feeding, but the common crusher has the main defects that the common silage is not uniformly crushed, the fineness of the crushed silage is large or small, particularly large straws are easy to exist, the liquid feed requires that the silage is uniformly crushed into powder to be directly added, otherwise, the blockage of a feeding pipeline is easily caused, and the like, and the automatic feeding cannot be realized. At present, a common grinder can only grind once and then screen the large feed, and then screen out the large feed to grind again, so that the grinding efficiency is low, the workload is large, the cost is high, and the development of the breeding industry is restricted.

Therefore, the problem of smashing silage in the pig industry becomes a technical problem to be solved urgently in the industry.
