Ventilation system for multi-unit row piggery

Abstract

The invention provides a ventilation system for a multi-unit row piggery. The wall of the left side of an entrance of each unit of the row piggery is provided with a medium ventilation window, a big ventilation window and a small ventilation window in sequence from left to right, and the wall of the right side of the entrance of each unit of the row piggery is provided with a big ventilation window, a big ventilation window and a medium ventilation window in sequence from left to right; the big ventilation windows, the medium ventilation windows and the small ventilation windows each comprises a ventilation window opening formed in the walls of the piggery; the inner side of each ventilation window opening is provided with a shutter, a horizontal transverse support plate is arranged in each ventilation window opening and provided with a motor, an output shaft of each motor is provided with rotation fan blades, the peripheries of the rotation fan blades are provided with protective air guide sleeves, and each protective air guide sleeve is provided with a protective grill. According to the ventilation system for the multi-unit row piggery, the ventilation quantity and the ventilation time and space can be controlled as needed, ventilating is even and balanced, therefore the suitable ventilation quantity of the piggery can be kept in all seasons and under various weather conditions, and the pig raising environment, the pig comfort degree and the pig production rate are improved.

Description

technical field [0001] The invention relates to pig breeding equipment, in particular to a ventilation system for a multi-unit row pig house. Background technique [0002] There are two purposes of ventilation in the pig house. One is to increase the air flow to make the pigs feel comfortable when the temperature is high, so as to alleviate the adverse effects of high temperature on the pigs; the other is to ventilate the pig house when the pig house is closed. The dirty air in the house can be improved by introducing fresh air outside the house, thereby improving the air quality in the house. Ventilation is one of the important ways to regulate the environment of pig houses. Proper ventilation design should provide sufficient maximum ventilation rate in summer and appropriate minimum ventilation rate in winter. In high-temperature seasons, ventilation inside the house can keep the temperature inside the house not higher than the temperature outside the house. Wit...
