Device for killing livestock by using carbon dioxide

Abstract

The invention discloses a device for killing livestock by using carbon dioxide, and relates to the technical field of livestock processing. The device comprises a fixed base, and the fixed base is fixedly connected with a closed chamber; sealing doors are rotationally arranged on the two sides of a sealing chamber where carbon dioxide is about to be introduced, a horizontal bevel gear is fixedly connected to the top of a rotating shaft of each sealing door, and a vertical bevel gear is rotationally arranged at the position, above the horizontal bevel gears, of the sealing chamber; wherein theleft closing plate and the right closing plate are coaxially and fixedly connected with a bus wheel and are respectively controlled on the connecting pipe through ropes, closing holes are formed in the middle positions of the left closing plate and the right closing plate, the connecting pipe is not closed by the left closing plate and the right closing plate in an initial state, and carbon dioxide can be discharged into the closed chamber from the connecting pipe at the moment, when the sealing door on any side of the two sides of the sealed chamber is not completely closed, the sealing doorrotating shaft forces the bus wheel to rotate to pull the left sealing plate or the right sealing plate to move upwards through the rope to seal the connecting pipe, and the carbon dioxide storage tank stops supplying carbon dioxide into the sealed chamber at the moment.

Description

technical field [0001] The invention relates to the technical field of livestock processing, in particular to a device for killing livestock by using carbon dioxide. Background technique [0002] Pigs generally refer to livestock. The pig is the end of the zodiac, also known as Hai. Mammals have stout bodies, short limbs, and long snouts. The meat is edible, the skin can be tanned, the body is fat and the limbs are short, the nature is gentle, the adaptability is strong, easy to raise, and the reproduction is fast. There are black, white, sauce red or black and white flowers and other colors. Pigs can be bred 5-12 months after birth, and the gestation period is about 4 months. The average lifespan of a pig is 20 years. Pigs have early sexual maturity, short gestation period, large litter size, short generation interval, fast turnover, easy multiplication, and rapid growth. Therefore, pigs are one of the main sources of meat for humans. [0003] At present, there are man...

Problems solved by technology

[0005] The purpose of the present invention is to solve the single structure of the closed chamber used for euthanasia (filling with carbon dioxide) in the prior art, lacking a safety control supply device for carbon dioxide, when the closed door for entering and leaving the closed room is not completely closed, the airtight If the room still continues to feed carbon dioxide, it will be very easy to cause a large concentration of carbon dioxide leakage accidents, and a proposed device for killing livestock using carbon dioxide
