Corn straw fermentation device

Abstract

The invention relates to the technical field of agriculture, in particular to a corn straw fermentation device. The corn straw fermentation device comprises an operation frame, wherein a fermentationkettle is mounted in the operation frame, an in-kettle rotating shaft is mounted in the fermentation kettle and adopts an inner hollow structure, and the top of the in-kettle rotating shaft is an outer edge section which penetrates through the upper wall of a kettle body of the fermentation kettle to be exposed, and a feeding hopper is mounted at the top end. A built-in section is arranged in an inner cavity area of the in-kettle rotating shaft, a discharging section is arranged at the bottom of the built-in section, a plurality of discharging openings are formed on the outer wall of the discharging section, a plurality of cutter frames are mounted on the built-in section in an equal spacing manner, and cutting blades are mounted on the cutter frames and mounted in inner cavities of the cutter frames in a penetrating and inserting manner; and a limiting mounting block is arranged at the mounting end of each cutting blade, a connecting spring is additionally mounted in the inner cavityof each cutter frame, and the connecting end of each connecting spring is connected with the corresponding limiting mounting block. According to the application, the immersion mixing effect of a cellulose fermentation agent on straws is integrally improved, and the fermentation quality of bottom materials is effectively ensured.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a corn stalk fermentation device. Background technique [0002] With the rapid development of my country's animal husbandry, new technologies for straw feed processing are emerging in an endless stream. In addition to direct feeding of corn stalks as feed, various processing technologies such as physics, chemistry, and biology have been promoted and applied in practice, and centralized large-scale processing has been realized. The straw micro-storage technology promotes the decomposition of straw cellulose, hemicellulose and lignin under closed anaerobic conditions by adding lignocellulose starter, improves the palatability of straw, increases its digestibility, and increases nutrition. Straw micro-storage technology can be used as a new technology for processing straw, and the feed produced is widely used in the feeding of herbivorous livestock. The successful applicatio...

Problems solved by technology

However, corn stalks have very strict requirements on the temperature and humidity in the fermentation tank during fermentation, and traditional corn stalk fermentation devices cannot meet many requirements during fermentation.

[0003] Chinese patent (authorized announcement number: CN209276533U) discloses a corn stalk fermentation device. The patent heats the water through the electric heating wire in the inner layer, and the stirring rod stirs the corn stalk evenly, making the fermentation more complete, shortening the fermentation time, and improving Fermentation efficiency; however, there are certain defects in this patent. The corn stalk itself has a large volume and high toughness, but the use of stirring rods cannot effectively achieve the purpose of stirring operations
