Drying and crushing device for cultivated excrement

Abstract

The invention relates to the field of livestock breeding, in particular to a drying and crushing device for cultivated excrement.The device comprises a shell, slide ways are uniformly arranged on theinner side wall of the shell, through holes are formed in the slide ways, and a fixed base is arranged on the outer side of the shell, and copper sliding platescooperated with the through holes are arranged on the inner side face of the fixed base; a heat conduction partition plate is arranged in the shell, protrusionscooperated with the slide ways are arranged at the edge of the heat conduction partition plate, a high-pressure hot steam inlet is formed in the lower end of the shell, and a material feeding port and an air outlet are formed in the side wall of the upper end of the shell;and theair outlet is connected with the deodorization chamber through a pipeline, hollow discs which are crossed with oneanother are arranged on the top surface in the shell, the top of the shell is provided with cutterscooperated with the hollow discs, the cutters are arranged on a knife rest, and a lifting mechanism is arranged at the upper end of the knife rest. According to the device, excrement can be effectively dried, compressed and crushed, storage is facilitated, and the fertilizer efficiency is effectively kept, an odor treatment device is comprehensively arranged,so that the pollution ofthe excrement to the air is reduced;and the device is simple in structure, novel in design, convenient to operate and high in practicability.

Description

technical field [0001] The invention relates to the field of livestock breeding, in particular to a drying and crushing device for breeding manure. Background technique [0002] In the field of livestock breeding, the treatment of livestock manure is a headache for farmers. Livestock manure is often not properly treated, and long-term accumulation is easy to cause environmental pollution. Moreover, livestock manure is also a kind of organic fertilizer, which can promote the growth of crops. grow. Existing breeding manure is usually directly sprinkled on the upper soil layer as fertilizer. Due to the poor dryness of the manure, it cannot be evenly distributed on the upper soil layer, and it is not conducive to direct absorption by plant roots. It is also a big problem to store the feces with a strong odor. During the feces treatment, the feces cannot be effectively dried, and the feces cannot be effectively crushed, so that the feces cannot be stored in bags. Long-term stora...

Problems solved by technology

Existing breeding manure is usually directly sprinkled on the upper soil layer as fertilizer. Due to the poor dryness of the manure, it cannot be evenly distributed on the upper soil layer, and it is not conducive to direct absorption by plant roots. It is also a big problem to store the feces with a strong odor. During the feces treatment, the feces cannot be effectively dried, and the feces cannot be effectively crushed, so that the feces cannot be stored in bags. Long-term storage in the open air will greatly reduce the fertilizer efficiency. In addition, the existing feces treatment workplace environment The smell is too heavy, which seriously affects the health of the staff, and the work cannot be carried out efficiently
