Description

Technical Field

[0001] The invention relates to the technical field of dairy cow breeding, and in particular to a feed delivery device for dairy cow breeding. Background Art

[0002] Milk is one of the oldest natural beverages and is known as "white blood". Milk is rich in minerals, calcium, phosphorus, iron, zinc, copper, manganese, and molybdenum. It is the best source of calcium for the human body, and the calcium-phosphorus ratio is very appropriate, which is conducive to calcium absorption. With the improvement of people's living standards, the demand for milk has gradually increased, so large-scale dairy cow breeding is needed.

[0003] With the development of dairy farming, a set of standardized farming processes including breeding, reproduction, feeding, and sanitation and epidemic prevention has gradually been formed. Among them, feeding includes two key links: feed supply and feeding management. The quality of feed and the rationality of feeding are important factors affecting the nutrition of dairy cows and the quality of milk production.

[0004] Specifically speaking of feed supply, it mainly includes the collection, processing and storage of feed. Considering the nutritional content and cost, hay, alfalfa, oat grass, cotton seeds, etc. are mostly concentrated as seasonal feed to ensure a balanced supply throughout the year. From the processing point of view, the above-mentioned forages are of different shapes and lengths, which are difficult to store in large quantities and will not be used directly as feed. They are usually processed into silage, which is convenient for storage and feeding on the one hand, and is also beneficial for dairy cows to eat and digest on the other.

[0005] From the perspective of feeding management, feeding should be carried out according to feeding specifications, no piles in the trough, no empty troughs, and a reasonable combination of fine and roughage. Feeding should be done at regular times and in fixed quantities, with less feeding and more frequent additions, and moldy, spoiled, and frozen feed should not be fed.

[0006] With the development of technology, computer-controlled mechanized feeding systems have become more popular and are gradually replacing manual feeding methods due to their advantages of simple operation, time saving, and high feeding accuracy.

[0007] However, due to technical imperfections, the existing mechanized feeding system still has certain defects in application, including: 1. The feed is uneven in size and difficult to unify. Specifically, some silage is prone to moisture and agglomeration during storage. On the one hand, the agglomerated feed is not conducive to the cows' consumption and digestion due to its uneven size. On the other hand, it is easy to cause blockage of the conveying pipeline during long-distance transportation and distribution.

[0008] 2. The problem of inconvenient drinking water supply during the feed delivery process. Specifically, drinking water needs to be supplied at the same time during the feed delivery process, but during the supply process, solid feed should be prevented from mixing with drinking water to avoid secondary agglomeration.

[0009] 3. When feeding individually confined dairy cows, it is difficult to achieve the goal of feeding at a fixed point, at a fixed time, and with a fixed amount of feed.

[0010] 4. After feeding, feed residues are likely to remain in the delivery pipeline, which is difficult to clean.

[0011] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention
