Dry fermentation device of straw

Abstract

The invention discloses a dry fermentation device of straw. Fixing blocks are fixedly mounted at two ends of a base through screws, a through hole is formed in the outer wall of one side of one fixingblock, a rotating rod is inserted in the through hole, a handle is mounted at one end, located outside the fixing block, of the rotating rod, a driving wheel is fixedly mounted at one end, located inthe fixing block, of the rotating rod in a threaded manner, a driven wheel is in meshed connection with the outer wall of the driving wheel, a movable block is arranged in the center of the driven wheel, a first lock block is welded on the inner wall of the movable block, the movable block adopts a hollow structure, a bolt is inserted in one end of the movable block, the outer wall of the bolt issleeved with a compression spring, a second lock block is fixedly mounted at one end, close to the first lock block, of the bolt in a threaded manner, a fixing rod is connected with one end of the second lock block, and a fermentation tank is welded at one end of the fixing rod. The straw is fermented and subjected to closed treatment by the fermentation tank, emission of odors during fermentation is reduced, fermentation is performed separately, the fermentation dates are clear, and more sufficient fermentation can be realized.

Description

technical field [0001] The invention relates to the technical field of straw fermentation, in particular to a straw dry fermentation device. Background technique [0002] With the development of my country's planting and breeding industries, the effective treatment of crop straw and breeding waste is becoming more and more important and urgent. According to statistics, my country produces more than 700 million tons of crop straw every year, but only about 30% is used as raw materials for the paper industry, construction industry and handicraft industry, and the remaining more than 500 million tons of straw are burned or discarded, which not only causes waste, but also causes a lot of waste. Incineration, environmental pollution, soil mineralization, and even other social losses. The existing straw recycling as animal husbandry feed must be fermented, but the existing fermentation process is unevenly fermented, most of the fermentation is deposited at the bottom of the straw ...

According to statistics, my country produces more than 700 million tons of crop straws every year, but only about 30% are used as raw materials for the paper industry, construction industry and handicraft industry, and the remaining more than 500 million tons of straws are burned or discarded, which not only causes waste, but also causes a lot of waste. Incineration, environmental pollution, soil mineralization, and even other social losses

The existing straw recycling as animal husbandry feed must be fermented, but the existing fermentation process is unevenly fermented, and most of the fermentation is deposited at the bottom of the straw pile, and the fermentation efficiency is low
