Device for making cow bed regeneration packing through solid cow dung

Abstract

The invention relates to the technical field of cow breeding farm excrement resourcing, in particular to a device for making cow bed regeneration packing through solid cow dung. The device comprises a box, a feeding unit, a discharging unit, a conveying unit and an air inlet heating unit; the box is provided with a feed port, a discharge port, multiple air inlets and an air outlet; the feeding unit is connected with the feed port, the discharging unit is connected with the discharge port, the conveying unit is arranged in the box, the two ends, in the conveying direction, of the conveying unit are arranged corresponding to the feed port and the discharge port respectively, the air inlets are arranged at intervals in the conveying direction of the conveying unit, the air inlet heating unit is connected with the air inlets and used for conveying hot wind to materials conveyed on the conveying unit so as to achieve drying and sterilizing effects, gas completing drying and sterilizing is discharged from the discharge port, and secondary soaking of dried materials is avoided. The device is simple in structure, the materials pass through multiple air inlets in the conveying process on the conveying unit, multiple drying and sterilizing are achieved, and the drying and sterilizing effects are improved.

Description

technical field [0001] The invention relates to the technical field of resource utilization of cow manure in dairy farms, in particular to a device for producing cattle bedding regeneration bedding from solid cow dung. Background technique [0002] With the large-scale development of dairy farming, a large amount of manure discharged from dairy farms has become an important bottleneck restricting the development of the dairy industry. At the same time, the use of beds in scattered stalls in modern cowsheds has made the source and safety of bedding materials a major challenge for dairy farming. Another problem. At present, the methods of utilizing manure from dairy farms mainly include anaerobic fermentation and composting, and the main products are biogas and fertilizer. Utilizing manure to produce litter is an emerging method of manure resource utilization, which can provide sufficient source of bedding for dairy farms while solving the problem of manure treatment in dairy...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to use a belt-type hot air drying system to replace the traditional drum-type aerobic fermentation system, to solve the problems of long production time of litter, substandard moisture content of finished litter, incomplete sterilization and disinfection, etc. When using a multi-layer mesh belt hot air dryer to dry and sterilize cow dung, the air volume passing through the surface of the conveyor belt is small, the wind energy is seriously wasted, and the structure is complicated.
