Device for making bio-fertilizer from straw

Abstract

The invention discloses a device for making a bio-fertilizer from straw. The device includes a segment cutting apparatus, a drying apparatus, a crushing apparatus, a reservoir and a fermentation tank.The head and tail ends of a first conveying device are respectively arranged at a discharge port of the segment cutting apparatus and an inlet of the drying apparatus, the head and tail ends of a second conveying device are respectively arranged at a discharge port of the drying apparatus and an inlet of the crushing apparatus, the discharge port of the crushing apparatus is connected to the fermentation tank, the drying apparatus is equipped with a water collection port, and the reservoir is connected to the water collection port and the fermentation tank respectively. The device for makinga bio-fertilizer from straw provided by the invention can improve the straw crushing effect, and also can keep consistent moisture in the straw so as to be convenient for control of the fermentation humidity and achieve a better and uniform fermentation effect.

Description

technical field [0001] The invention relates to a device for making biological fertilizer, in particular to a device for making biological fertilizer by using straw. Background technique [0002] Burning straw is one of the main sources of pollution in rural areas of our country. Although the country has already banned the burning of straw, this phenomenon still occurs frequently. Therefore, turning straws into treasures to increase farmers' income is the most effective way to eliminate straw burning. Straw is a kind of biomass material, which can be made into biological feed after fermentation for feeding cattle and sheep. However, the fermented straw needs to be crushed first. For the freshly harvested straw, the moisture is high, the toughness is strong, and it is difficult to crush; in addition, the fermentation temperature and fermentation humidity need to be controlled during the fermentation process. Since the freshly harvested straw contains water and the water cont...

Problems solved by technology

However, the fermented straw needs to be crushed first. For the freshly harvested straw, the moisture is high, the toughness is strong, and it is difficult to crush; in addition, the fermentation temperature and fermentation humidity need to be controlled during the fermentation process. Since the freshly harvested straw contains water and the water content is inconsistent, It makes it difficult to control the humidity of fermentation, resulting in uneven fermentation effect
