Supply air rate controlling device of hatching machine

Abstract

The invention discloses a supply air rate controlling device of a hatching machine, which relates to a ventilating unit on the hatching machine and is arranged on a panel of the top part of the hatching machine. The invention is characterized in that the supply air rate controlling device is connected with the inner part of the hatching machine through a through hole arranged on the panel on the top part of the hatching machine, an air inlet cover is installed on the lower part of the through hole, and the air inlet cover is located right above a fan; the supply air rate controlling device comprises a ventilation door and a ventilation door electrical machine assembly, the ventilation door electrical machine assembly comprises a box body, a transmission device is arranged in the box body, the box body is close to one end of the ventilation door and connects the ventilation door and the transmission device through a connecting rod, and the other end of the ventilation door is connected with the transmission device through a servo motor; and the two ends of the ventilation door are provided with a track groove, the servo motor drives the ventilation door to move back and forth on the track groove through the connecting rod, and regulates the supply air rate. The supply air rate controlling device has the advantages that the structure arrangement of the controlling device is simple and reasonable, the supply air rate can be automatically controlled through a controlling system and the servo motor, and the stable temperature field in the hatching machine is ensured, and the birth rate and health rate are improved.

Description

technical field [0001] The invention relates to a ventilation device on an incubator, in particular to a regulating device for the air intake of the incubator. Background technique [0002] Incubation equipment has been widely used in poultry hatching, biopharmaceuticals, laboratories, etc., and its function and quality requirements have also been greatly improved. It includes temperature control system, egg turning system, humidification system, ventilation system and the material selection and installation structure of each component are very important. Different temperature and humidity are required in different periods of incubation, so it is very important to adjust the temperature and humidity in the incubator. The temperature control inside is mainly accomplished through the ventilation system. When the temperature inside the box is high, a proper amount of cold air is introduced through the ventilation system. When the temperature inside the box is low, the ventilat...

Problems solved by technology

But in the existing equipment, its ventilation system is not well controlled

Under normal circumstances, it is controlled by humans. When the temperature in the box is observed to be too high through the thermometer, cold air is introduced through the blower, otherwise the ventilation device is turned off. This method makes the temperature control in the box inaccurate, and the hatching The required temperature is related to the hatching rate and healthy chick rate, so it is very important to control the air volume in the incubator, and it must be accurately controlled
