Description

TECHNICAL FIELD

[0001] The present application relates to the field of ecological fertilizer preparation, in particular, relates to an agricultural straw fermentation device for ecological fertilizer preparation. BACKGROUND

[0002] Straw fermentation is under anaerobic conditions in a closed environment, which promotes the decomposition of straw cellulose, hemicellulose and lignin, improves the palatability of straw, increases the digestibility, and increases the nutrition. The processed feed is widely used in the feeding of herbivorous livestock. The successful application of this technology opens up a new way for the effective utilization of crop straw in rural areas and the development of animal husbandry in rural areas.

[0003] The patent document with publication number CN109384483B discloses an agricultural straw recycling fermentation composting device, which aims at the low efficiency of straw stirring and chopping, and does not effectively crush the crushed straw, which is not conducive to straw juice extraction and straw recycling. At the same time, when using straw material, the cost problem is not noticed, and the following scheme is proposed, which includes support legs, two support legs, the bottom outer wall of each support leg is fixed with a shock pad through bolts, and the opposite outer wall of each support leg is fixed with a same composting tank through bolts, the top outer wall of the composting tank is fixed with a fermentation outer tank through bolts, and the bottom outer wall of the fermentation outer tank is provided with a through hole, the inner wall of the through hole is fixed with two discharge hoppers through bolts, and the inner wall of each discharge hopper is connected with a material guide pipe through threads.

[0004] Although the above-mentioned application improves the practicability of the whole device and can strengthen the cutting speed of the stirring knife, only the elastic protrusions can apply a reverse force to the straw by their own deformation rebound to form a similar "soft rolling" effect to promote fiber breakage and juice exudation during use. However, the free falling trajectory of the straw is uncontrollable, and part of the straw may bypass the protrusions or only be subjected to single collision, resulting in uneven fiber treatment.
