Ventilation device for poultry breeding greenhouse

Abstract

The invention discloses a ventilation device for a poultry breeding greenhouse, and relates to the technical field of agriculture. The ventilation device aims to solve the problem that the environmentis affected due to the fact that peculiar smell gas inside the greenhouse is diffused when a greenhouse door is mostly directly opened or a film is opened for direct ventilation in the ventilation work of the breeding greenhouse. The ventilation device specifically comprises a base box, wherein an air box is fixedly arranged at the top of the base box, and an exhaust fan is fixedly arranged at the top end of the air box; and a main air duct of an arc-shaped structure is fixedly arranged at the top end of the air box, auxiliary air ducts are fixedly arranged on the two sides of the main air duct, and ventilation holes are formed in the side faces of the two auxiliary air ducts. According to the ventilation device for the poultry breeding greenhouse, air pumped out of the greenhouse is exhausted through the interior of the base box, in the daily ventilation and exhaust process, the air is slowly released to the outer side through a soil particle layer, and the exhausted air is adsorbedand purified through the soil particle layer, so that peculiar smells of the exhausted air inside the greenhouse are eliminated; and a purification filter material is simple and easy to obtain, and the soil particle layer is periodically replaced, so that the air purification cost is conveniently reduced.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a ventilation device for poultry breeding greenhouses. Background technique [0002] Poultry refers to artificially raised birds, mainly for their meat, eggs and feathers, but also for other purposes. Generally, they are pheasants and ducks, such as chickens, ducks, geese, etc. There are also birds of other families such as turkeys, pigeons, quails and various songbirds. In addition to providing human meat and eggs, poultry also provide their feathers and feces. It also has important economic value. Chicken is rich in protein, and its fat contains unsaturated fatty acids, so it is a better protein food for the elderly and patients with cardiovascular diseases. [0003] The cold resistance of chickens is poor. The body temperature of the newly hatched chicks is 3°C lower than that of adult chickens, and it takes 10 days to reach normal body temperature. In addition, the chi...

Problems solved by technology

[0003] The cold resistance of chickens is poor. The body temperature of the newly hatched chicks is 3°C lower than that of adult chickens, and it takes 10 days to reach normal body temperature. In addition, the chicks have short and thin fluff and cannot keep out the cold, so they are not adaptable to the environment. Only by artificial heat preservation can the chicks grow and develop normally. Breeding greenhouses can improve the survival rate of chicks. At present, most of the ventilation work for breeding greenhouses is to directly open the greenhouse door or lift the film to ventilate directly. The odor gas inside the greenhouse is emitted, which affects the environment.
