The laser range finder components is characterized by an above-average measured value output frequency, up to 8hz. The miniature laser distance module is also suitable for monitoring defined distance and height during transport.
Longitudinal ventilation installation of broiler houses is simple and cost-effective
When the length of the house is more than 80 meters and the span is more than 10 meters, longitudinal ventilation shall be adopted. In this way, the rationality of the ventilation design of the chicken house is optimized, the installation cost is reduced, and the ideal ventilation effect can also be obtained. Longitudinal ventilation refers to installing the fan on the side wall of the broiler house, and setting up an air inlet on the opposite side of the fan or the opposite side walls of the gable, so that the fresh air can penetrate into the hen house under negative pressure. Trail out of homes. The exhaust fan is 1.25~1.40 meters long. The fan of the exhaust fan should be at a 100 degree angle to the wall surface. The ventilation efficiency can be increased by 10%. The air velocity is 2.0~2.2 meters/second. The distance between each fan is 2.5~3.0 meters. . During the high temperature season in summer, in order to effectively reduce the temperature of the chicken house, it is usually necessary to install a wet curtain at the air inlet, ie the temperature of the wet curtain is reduced. For ventilation calculations, see Horizontal Ventilation System. Due to the advantages of simple design and installation, low cost, good ventilation and cooling effect, the longitudinal ventilation system of the chicken house has been widely used in the production of contemporary chickens.
