CLosed type underground manure scraping and automatic manure removaL system for animaL house

Abstract

The invention beLongs to the fieLd of Livestock environmentaL engineering, and reLates to a cLosed type underground manure scraping and automatic manure removaL system for an animaL house. The probLemthat the internaL environment of the animaL house needs to be communicated with the exterior of a hog house in the manure scraping process is soLved, the controL energy consumption for the animaL house environment is Lowered, and energy-saving production is achieved; the probLem that stink gas inside the animaL house is spread is soLved, the contamination caused by a Livestock farm to the surrounding air environment is Lowered, and environment-friendLy production can be achieved; the probLem of cross infection of diseases between different Livestock regions is soLved, the production disease controL capabiLity can be improved, and safety production is achieved; fuLL-automatic manure scraping, manure removaL and manure conveying are achieved through an integrated system, the Labor amount ofworkers is Lowered, the Labor environment of workers is ensured, and fuLL-automatic non-poLLution manure removaL of the animaL husbandry is achieved.

Description

technical field [0001] The invention belongs to the field of animal husbandry environmental engineering and relates to an underground manure scraping and automatic manure cleaning system for closed livestock houses. Background technique [0002] Manure cleaning is a main content of animal husbandry production management, and it is also one of the important links in the comprehensive management of manure and the regulation of animal husbandry environment. At present, the animal husbandry mostly adopts three methods of washing manure, water soaking manure and dry manure cleaning. The labor intensity of water washing manure is low and the cleanliness is high, but the water consumption is huge and the amount of sewage is high; Manure saves water, but it is easy to ferment and produce harmful gas, and the long-term soaking of manure in urine and water will lead to the loss of nutrients and reduce the value of manure resource utilization; there are two types of dry manure cleaning:...

AI Technical Summary

Problems solved by technology

[0005] The existing underground mechanical manure scraping pig house usually cleans the manure inside the pig house to the outside of the house. Therefore, in order to ensure the operation of the manure scraping system in the ditch, the underground manure ditch is actually to separate the environment inside and outside the house. However, although this connection meets the requirements for manure cleaning, it has the following fatal flaws: ①For the currently commonly used closed pig houses, the connection of the manure ditch will have a negative impact on the environment regulation in the house. In particular, it has a negative impact on the ventilation system in the pig house. The air flow should enter the pig house through a specific air inlet, but the connection of the manure ditch adds an air inlet in disguise, which seriously disturbs the air flow distribution in the house, which is not conducive to the pig house. Environmental regulation, and at the same time, due to the insufficient airtightness of the underground manure ditch in the pig house, the energy consumption required for ventilation, heat preservation, and heat insulation in the pig house will greatly increase, which will increase the cost of environmental regulation in the pig house; ②The communication of manure in the pig house It is often the source of pig farm pollution, including odorous gas, airborne microorganisms, dust and other pollutants. The manure ditch connects the inside and outside of the pig house, which is not conducive to the control of the external air environment of the pig house, and does not meet environmental protection requirements; ③The manure ditch of the pig house It is easy to spread pathogenic microorganisms in the air, causing cross-infection and disease transmission between different pig houses, between pigs and humans, and between different farms, and there are serious safety hazards in disease prevention and control.
