According to the function, the pig farm equipment can be divided into feeding and drinking water equipment, heating equipment, ventilation equipment and cooling equipment.
First, feeding drinking water equipment
Feeding drinking water equipment is the most basic equipment for raising pigs. The common feeding equipment includes a sow trough, a piglet feed trough, a double-sided feed trough, and an automatic feed trough. Pig drinking fountains are mainly bowl-type, duck-billed, nipple-type, trough several.
Application of pig feed trough should pay attention to whether the capacity of the feed trough meets the amount of pigs. Drinkers should pay attention to safety, sealing, and should pay attention to the installation location and installation height of drinking fountains.
Second, heating equipment
Pig house heating heating and partial heating two. Central heating uses a centralized heating device to generate heat medium. The heat medium is then sent to the radiator in the pig house through pipes, and the air in the pig house is heated to maintain a suitable temperature in the pig house. Central heating equipment is a hot stove. Local heating is an energy-saving, environmentally-friendly, and highly efficient heating method. Common heating equipment includes floor heating, hot plates, and infrared heat lamps.
Third, ventilation equipment
Ventilators suitable for use in pig farms are mostly large diameter, low speed, low power fans. This fan has a large amount of ventilation, low noise, low power consumption, and durability.
Ventilation and ventilation should pay attention to the following issues: (1) Avoid fan ventilation and short circuit, must not be set on the wall of the fan, the bottom is through the door, so that the air flow to form a short circuit; (2) If unilateral exhaust, should be two The ventilation outlets on the side adjacent pig houses are located on the opposite side to prevent one of the discharged air from being immediately inhaled by another pig house; (3) Try to make the airflow pass through most of the space in the pig house, especially the ditch On the other hand, do not create dead ends to achieve ventilation.
Fourth, cooling equipment
Although ventilation is an effective means of cooling, it can only reduce the temperature of the shepherd to a temperature close to the outside ambient temperature. When the outside ambient temperature is greater than the maximum temperature limit of the pig production (27 to 30°C), the ventilation is At the same time, cooling measures should also be taken to ensure that the temperature is controlled within a suitable range.
The cooling system commonly used in pig farms is wet curtain-fan cooling system, spray cooling system, spray cooling system and dripping cooling system. Because the latter three kinds of cooling systems have high humidity, they are not suitable for delivery rooms and toilets. The wet curtain-fan cooling system is currently the most mature evaporative cooling system. Its evaporative cooling efficiency can reach 75-90%, and it has been widely used throughout the world.
