Pig house ventilation device

Abstract

The invention discloses a pig house ventilation device, which comprises a pig house, the outer surface of the top of the pig house is fixedly connected with exhausting cylinders by screws, the interior of the pig house is welded with a cross bar near the exhausting cylinders, an auxiliary fan is embedded in the cross bar, the outer surface of the bottom of the cross bar is fixedly connected with connecting rods near the auxiliary fan through screws, one side of each connecting rod is provided with a rotating shaft in a penetrating embedded way, the periphery of each rotating shaft is connectedwith a baffle plate, and a first ventilation fan and a second ventilation fan are embedded in each of two side walls of the pig house. In the invention, the defecation taste of pigs can be guided, isprevented from being affected by an air flow and flowing back into the pig house to cause heavy taste in air, affect the ventilation effect, cause breathing difficulty of farmers and the like, and the pig house ventilation device can realize mixed ventilation and replacement ventilation, can conveniently select different ventilation modes for four seasons according to the situation, is suitable for use in most pig houses, and can adjust the wind direction of wind blown out to meet the situation that pigs in a single fence do not need ventilation.

Description

technical field [0001] The invention relates to the technical field of pig house ventilation devices, in particular to a pig house ventilation device. Background technique [0002] With the improvement of the modernization level of pig raising, the requirements for the environment in the pig house are getting higher and higher. The ventilation system is a very important part of the pig house environment, and it has a direct relationship with the pig's work and habits. In theory, ventilation methods can be classified into two types of ventilation methods: mixing ventilation and displacement ventilation. [0003] The existing pig house ventilation device only pays attention to the ventilation of the pig’s residence. The smell of pig defecation is not guided, and it is easily affected by the air flow and flows back into the pig house, resulting in heavy air smell, affecting the ventilation effect, and breathing difficulties for the breeders. The pig house ventilation device in...

[0003] The existing pig house ventilation device only pays attention to the ventilation of the pig’s residence. The smell of pig defecation is not guided, and it is easily affected by the air flow and flows back into the pig house, resulting in heavy air smell, affecting the ventilation effect, and breathing difficulties for the breeders. The pig house ventilation device installs a ventilation method according to the wind speed preferences of the pigs and the conditions of the pigs in the pig house. It is inconvenient to change the use of the four seasons according to the situation, and it cannot be used in most pig houses. When the pigs in a single pen do not need ventilation, unable to adjust
