Fermentation device for returning straw to farmland

Abstract

The invention discloses a fermentation device for returning straw to farmland. The fermentation device comprises a bottom board, wherein the top of the bottom board is fixedly connected with a fermentation box, the right side of the top of the fermentation box is communicated with a crushing box, and the left side of the top of the fermentation box is fixedly connected with a first motor. The fermentation device is provided with the bottom board, the fermentation box, the crushing box, the first motor, a transmission rod, a crushing wheel, a feed port, a fixed box, a second motor, a first gear, a transmission column, a second gear, a stirring worm wheel, a stirring rod, a heat conduction board, a placement groove, a heating ring, a discharge tube, a first sealing cover, a second sealing cover and a sealing ring, thereby solving problems that existing fermentation device for returning straw to farmland has low fermentation efficiency and has the phenomenon of material blocking in discharging. The fermentation device for returning straw to farmland has the advantages of having high fermentation efficiency and being less likely to block the material during discharging, thereby being more practical and being convenient to use.

Description

technical field [0001] The invention relates to the technical field of straw returning machinery, in particular to a fermentation device for straw returning to the field. Background technique [0002] Straw returning to the field is a measure to increase soil fertility. It can increase fertilizer and production while eliminating the air pollution caused by straw burning. Straw returning to the field can increase soil organic matter, improve soil structure, and make the soil loose and porosity. Increase, reduce capacity, promote microbial activity and root system development of crops, return straw to the field to increase fertilizer and increase production significantly, generally can increase production by 5% to 10%, but if the method is not appropriate, it will also lead to an increase in soil pathogens, aggravation of crop diseases and lack of seedlings Therefore, only by taking reasonable measures to return straw to the field can a good effect of returning straw to the fi...
