Three-dimensional multi-layer pigsty capable of dry-cleaning manure without rinse

Abstract

The invention discloses a multi-layer three-dimensional pig house without washing and dry cleaning, which comprises a house body, a number of pig house layers are arranged in the house body, a number of pig pens are arranged in the middle of the pig house layer, and the floor of the pig house It is a excrement leaking floor, and it is characterized in that: more than one excrement discharge passage is provided below the excrement leakage floor, and the cross section of the excrement discharge passage is V-shaped with both sides inclined toward the middle, and the upper surface of the excrement discharge passage is Smooth surface, the bottom of the excrement passage is provided with a pig manure screw conveyor along the extension direction of the excrement passage. Connected with both sides of the V-shaped feces discharge channel, the conveying trough is provided with a screw conveying shaft, the side of the house is provided with a feces conveying pipe, and the feces outlet of each layer of conveying trough corresponds to the entrance of the feces conveying pipe Connection, the outlet of the feces pipe is provided with a septic tank.

Description

technical field [0001] The invention relates to a pig house, in particular to a multi-layer three-dimensional pig house without washing and cleaning manure. Background technique [0002] At present, my country's pig production is in the period of transformation from traditional pig industry to modern pig industry, and large-scale and industrialized pig farming are developing rapidly. The original pig house is difficult to realize industrialized pig raising. The reason is that the traditional pig farms are flat pig farms built on the ground, which occupy a large area. The overall ventilation effect is poor, and the exhaust gas produced by waste cannot be discharged from the pig house in time, which not only pollutes the air in the pig house, but also brings the germs and insect eggs in the waste into the pig's body, which is easy to cause infection of pigs in the pig house . [0003] Existing pig houses mainly use manual excrement cleaning, which consumes a lot of water for...

Problems solved by technology

The original pig house is difficult to realize industrialized pig raising. The reason is that the traditional pig farms are flat pig farms built on the ground, which occupy a large area. The overall ventilation effect is poor, and the exhaust gas produced by waste cannot be discharged from the pig house in time, which not only pollutes the air in the pig house, but also brings the germs and insect eggs in the waste into the pig's body, which is easy to cause infection of pigs in the pig house

[0003] Existing pig houses mainly use manual manure cleaning, which consumes a lot of water for flushing manure and seriously pollutes the environment

At present, most of the pig houses use solid ground, which requires manual excrement removal. Not only is the workload very heavy, but the sanitary conditions of the pens are very poor. Subsequent sewage treatment is difficult and the environment is seriously polluted

Some pig farms use overhead pig houses, and the bottom of the pig house is equipped with a slatted board, and the pig manure flows into the collection tank below at any time, and then the pig manure is scraped out through the manure scraper, but this method has a complicated structure and the pigs The feces cannot be completely cleaned, and the feces will remain for a long time, which will ferment and produce harmful substances, and the manure scraper is easily damaged
