Corn straw crushing device based on fertilizer production

Abstract

The invention discloses a corn straw crushing device for fertilizer production. The corn straw crushing device comprises a rotating shaft type crusher (1), a double-output-shaft motor (2) is mounted on the rotating shaft type crusher (1), and a chopping mechanism is mounted on a feeding hole of the rotating shaft type crusher (1); driving belt wheels (3) are installed at the two ends of the double-output-shaft motor (2) respectively, the driving belt wheels (3) are in belt transmission fit with a secondary belt wheel (4) at the smashing shaft end of the rotating shaft type smashing machine (1) through a triangular belt, and the secondary belt wheel (4) is in belt transmission fit with a driven belt wheel (5) on the chopping mechanism through a triangular belt. According to the invention, a two-section type chopping mechanism is additionally arranged at the feed port part of a traditional rotating shaft type crusher, so that corn straws entering the crushing cavity are in a small-section type structural form, the phenomenon of winding a rotating shaft is avoided, the overall crushing effect is more thorough, and the subsequent fermentation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field related to corn stalks, in particular to a corn stalk crushing device for fertilizer production. Background technique [0002] Corn stalk is mainly used as feed for grain, economics, and forage. At the same time, corn stalk is also an important fertilizer resource in agricultural production. At present, the treatment method of corn stalk as base fertilizer is mainly two steps of crushing and fermentation. Among them, the crushing step The main reason is that the size of the straw crushed particles is the key to the later fermentation. At present, most of the common crushers use a high-speed rotating blade to crush and cut the straw, but most of these straw crushing devices are used. It is a common straw for corn stalk. It is well known that the overall length of corn stalk is long, and the stalk part of the stalk is hard in texture, with large deflection and flexibility. During the process of corn stalk crus...

Problems solved by technology

[0002] Corn stalks are grain, economy and feed crops that are mainly used as feed. At the same time, corn stalks are also important fertilizer resources for agricultural production. At present, corn stalks are mainly treated as a base fertilizer by two steps of crushing and fermentation. The crushing step It is more critical, and the main reason is that the size of straw crushed particles is the key to post-fermentation. At present, most common grinders use a high-speed rotating blade to crush and cut straw, but most of these straw crushing devices It is aimed at the common straw. It is well known that the overall length of corn straw is longer, and the stem part of the straw is hard in texture, with large deflection and flexibility. During the crushing process of corn straw, there is a high probability that the straw part will be entangled with the crushing shaft. superior
