Description

Technical Field

[0001] The invention relates to the technical field of silage fermentation, and in particular to a silage fermentation device and a fermentation method thereof for beef cattle breeding. Background Art

[0002] Silage is a type of feed made from plant feed with high water content after sealing and fermentation, mainly used to feed ruminants such as beef cattle. Its characteristics include: it is more storable than fresh feed, not easy to deteriorate, has stronger nutrients than dry feed, is rich in cellulose and crude protein, can provide the energy and nutrients required by beef cattle, has a sour and fragrant smell, is soft and juicy, is easy for beef cattle to eat and digest, takes up less space for storage, and has no safety hazards such as fire. The raw materials of silage should be selected from plant feed with high sugar content, good palatability, non-toxic and harmless, such as corn stalks, green grass, and forage. The silage fermentation device for beef cattle breeding is a kind of equipment specially designed for beef cattle farms. It is used to ferment silage raw materials (such as forage grass, corn stalks, etc.) under anaerobic conditions after chopping, adjusting moisture, filling, compacting and sealing, and finally make silage suitable for beef cattle. This device not only improves the production efficiency and quality of silage, but also facilitates the storage and use of feed.

[0003] After searching, the Chinese patent number CN217202679U discloses a silage fermentation device for beef cattle breeding, including: a fermentation device body, the fermentation device body includes a fermentation barrel, a feed port is fixedly installed on the side wall of the fermentation barrel, an observation window is fixedly installed on the front of the fermentation barrel, a capacity scale is fixedly installed on one side of the observation window, the stirring structure includes a motor, the motor is fixedly installed on the top surface of the fermentation barrel, the output end of the motor is fixedly connected to a gear, and a propeller is movably installed inside the fermentation barrel. The fermentation device can automatically stir and mix the feed through the rotation of the propeller, which is more convenient, and when the propeller rotates, it can drive the counterweight block to extend from the surface, so as to drive the pressure block to squeeze the pressure ring, and the pressure ring squeezes out the bacterial liquid absorbed by the sponge block so that it is evenly spread in the rolling feed.

[0004] However, during the actual use of the above-mentioned device, the propeller cannot adjust the stirring depth during stirring, which easily leads to uneven stirring. After the stirring is completed, the propeller still stays in the silage to be fermented, affecting the fermentation efficiency. Moreover, when the silage to be fermented is small, the propeller blades of the device will make it difficult for the compacting mechanism to continue to descend and squeeze out the air, so that the amount of silage fermented by the device is limited and the working efficiency is low. Therefore, it is necessary to propose a silage fermentation device and a fermentation method for beef cattle breeding. Summary of the invention
