Temperature control principle of the present utility model and process are as follows:
The utility model requires airtight relatively than common hatch machine, sealed original exhaust outlet and the back air inlet gone up of common hatch machine, so in ambient temperature under the higher or more situation of hatching later stage chicken embryo heat production, the interior heat of case can occur can not in time shed, cause the too high phenomenon of temperature, so the utility model has increased an airtight hot channel.Temperature controlled processes of the present utility model is as follows:
Referring to work schematic diagram 2, Fig. 1, closed power switch is pressed start key, and machine main frame 1 sends electrical heating signal 122 to electrical heating wire, by electrical heating wire 19 beginning electrical heating; Aerofoil fan 20 rotates with gas in the blending bin, and temperature is evenly risen.Temp probe 4 detects temperature value, and this temperature value is passed to MUC monolithic main frame 1 by temperature signal line 8, and the numeral demonstration is also carried out the micro computer fuzzy control.Setting value during control system can relatively be remembered according to factors such as environmental temperature, machine heat radiation and the heat production of kind egg is adjusted heating power automatically, has eliminated the temperature field fluctuation as much as possible.If the heat that produces can not in time scatter and disappear, temperature surpasses when setting value 0.3 ℃, and system host 1 outgoing signal 121 is opened exhaust fan 29 automatically, makes gas enter airtight hot channel 30, enters in the case after the cooling again.So both reduce temperature, saved low-oxygen gas again, significantly reduced the consumption of nitrogen.The purposes of mercury conductivity meter 31 is that superhigh temperature is reported to the police and the temperature control of meeting an urgent need, and when temperature surpassed 0.5 ℃ of setting value, circuit was connected in the mercury contact up and down, and signal is passed to main frame 1, and main frame 1 is reported to the police automatically, and cuts off heating.

Because original hatch machine is to establish tank in case, during humidification, wheel turns in the motor drives tank increases disengagement area, reaches the purpose of humidification.This mode, in an airtight relatively chest, it is too high humidity to occur through regular meeting, uncontrollable.So the utility model humidity control section is on the basis of original hatch machine system, reequiped humidification method, removed tank and electromotor, the circuit of controlling the electromotor signal has originally been connected one be placed on the outer humidifier of case, during humidification, the steam of generation enters in the case by adding wet hole.Also combination is referring to Fig. 1 referring to structural representation Fig. 3, and the course of work is as follows:
Oxygen concentration control principle of the present utility model and process:
See also Fig. 4, the oxygen concentration that oxygen probe 6 detects in the incubator box 100, and pass the signal to oxygen private host 2, convert data signal and demonstration to.According to test requirements document, set certain oxygen density value, relay 211 contacts conversion current potential promptly is set, referring to Fig. 5; During beginning, oxygen concentration is higher than setting value, and normally closed relay control magnetic valve is opened, and post-decompression high pure nitrogen enters in the case by glass rotameter 26, magnetic valve 25.Regulate glass rotameter 26, can change intake velocity, change the time of setting concentration that reaches.The nitrogen that enters in the case is mixed with gas in the case by aerofoil fan 20 immediately, and oxygen concentration is evenly reduced.When oxygen concentration was reduced to setting value-0.2%, relay 211 contacts disconnected, and magnetic valve 25 cuts out, and nitrogen stops to enter.Because exist oxygen partial pressure poor inside and outside the case, casing neither be airtight fully, so extraneous air can slowly infilter in the case, oxygen concentration is gone up, and surpasses setting value+0.2% o'clock, and magnetic valve 25 reopens, nitrogen enters, thereby makes oxygen concentration be controlled at the scope of setting value.The work schematic diagram is seen Fig. 4, and the magnetic valve operating circuit is seen Fig. 5, magnetic valve work has automatically, manual, stop three kinds of modes; Magnetic valve one end be connected with power supply 400, when the other end was connected with the contact 212 of relay 211, its work was controlled by oxygen concentration signals automatically; When being connected with power contact 214, its continuous operation; When being connected with break contact 213, it quits work.
Gas concentration lwevel control principle of the present utility model and process:
Referring to Fig. 6 is carbon dioxide concentration control system work schematic diagram, and egg is grown and can constantly be produced CO
2, and CO
2Excessive concentration can influence embryo's growth again.It is reported CO
2Concentration is 0.5% o'clock, and egg hatching rate the highest (Barott, 1937) is so we design CO in the case
2Concentration is not higher than 0.5%.CO
2Probe 7 utilizes infrared principles to detect CO
2Concentration is sent on the main frame 3 and carries out numeral and shows.When concentration reaches or be higher than 0.5%, relay 311 closures, small blower 23 work of control blow into CO with gas in the case
