Description

The thermostatic type hatch machine

The utility model relates to a kind of hatch machine, creates the hatch machine of a more stable environmental temperature particularly for kind of egg.

For hatch machine, subject matter is exactly to improve incubation rate guaranteeing to hatch on the basis of high-quality young bird, and improves the at first just accurate temperature in the control hatch machine of incubation rate.Figure 3 shows that existing large-scale hatch machine, the egg unwheeling 2 of packing in casing sequences 6 egg unwheelings side by side, and each egg unwheeling has thousands of eggs, and it is after incubating the 3rd day, 6 days, 9 days successively that the egg unwheeling begins from a left side ...Controlling the air of temperature well, force to deliver in the egg unwheeling 2 then, the kind egg that is contained in the egg unwheeling was hatched in the regular hour with fan 3.The hatch machine of this structure is provided with heating/cooling device (heat exchanger of heating tube and cooling usefulness) near fan 3, it is the temperature sensor 4 control temperature by egg unwheeling exit.When the mensuration temperature of temperature sensor 4 was higher than set temperature value, cooling device cooled off air; When the mensuration temperature was lower than design temperature, heater was to air heat; In the time of in the design temperature scope, have only fan 3 forced air supplies.

In the hatch machine of this structure, temperature sensor 4 is only to detect the air themperature that flows in the egg unwheeling.Though it can control near the air themperature (promptly flowing into the air themperature in the egg unwheeling) the temperature sensor 4 exactly, but in the hatch machine of tunnel type, owing to plant the warming-up effect of egg self, the air themperature that process kind of egg ejects is that the temperature of egg unwheeling import department (B selects) can change along with kind of the packing state into of egg, make the temperature can not be constant, cause incubation rate to reduce.Because the height of incubation temperature directly has influence on the length of brooding time, and brooding time is too short or long not only influential to incubation rate, and is also influential to the quality of fowl young bird.

As seen, in the control of hatch machine, the most thorny is that the control air flow is through planting the recurrence temperature (being the temperature that the egg unwheeling B of import department is ordered) of discharging after the egg.Even the temperature that A is ordered accurately is controlled at uniform temperature, but the temperature that B selects is unstable because of the influence that is subjected to kind of an egg quantity, the factors such as variation on setting egg(s) date.If control heating-cooling device but only utilize sensor to measure the temperature that B orders, and controlling air themperature in the egg unwheeling with this, in fact also is infeasible.Because the temperature that A is ordered is heated after the cooling device control, it influences the temperature that B orders and need lag behind 30 minutes-60 minutes, thereby also can not accurately control temperature.

The purpose of this utility model is exactly the deficiency that overcomes existing hatch machine, and a kind of influence that is not subjected to egg unwheeling setting egg(s) situation is provided, and kind of egg is hatched under a desirable steady temperature environmental condition, the thermostatic type hatch machine that improves incubation rate and can hatch the young bird of high-quality.

For achieving the above object, the utility model provides a kind of thermostatic type hatch machine, comprise: the some egg unwheelings in casing and the casing, fan, and by thermometric degree sensor, air heat/cooling device, the attemperating unit that temperature setting device is formed, this temperature setting device is to control heating-cooling device according to the detection signal of temperature sensor, also comprise a humidity sensor, be characterized in: described temperature sensor is divided into master reference and correcting sensor, master reference is installed on the exit of egg unwheeling, correcting sensor is installed on the import department of egg unwheeling, and the temperature signal that temperature setting device detects according to correcting sensor is revised the design temperature of master reference.

The temperature signal control heating/cooling device 5 that the temperature setting device of the utility model thermostatic type hatch machine detects according to master reference 4A is by the output signal design temperature of correcting sensor 4B.The correcting sensor 4B that promptly surveys B point temperature does not directly control heating-cooling device 5, but control heating/cooling device 5 by the mensuration temperature of master reference 4A, correcting sensor 4B just revises the set temperature value of master reference 4A, the master reference 4A that was corrected directly controls heating-cooling device 5, and the recurrence temperature that B is ordered reaches setting value.Because heating/cooling device 5 is by the very little master reference 4A control of phenomenon time lag, too high or too low situation can not occur so return temperature in the control procedure.Secondly, the survey time returns the correcting sensor 4B of temperature all the time the design temperature of master reference device 4A being proofreaied and correct, thus return the variable effect that temperature is not subjected to the setting egg(s) situation, and control within the specific limits with being stabilized.Therefore, the utility model reduces kind of egg to greatest extent and goes into to incubate the influence of situation to incubation rate when hatching, can kind of egg be hatched under a desirable temperature environment condition with more constant control temperature, improves incubation rate and hatches the high-quality young bird.

Below in conjunction with an accompanying drawing and a preferred embodiment of the present utility model the constant temperature hatch machine is described further:

Fig. 3 is the structural representation of existing hatch machine;

Fig. 4 is a circuit diagram of the present utility model.

Referring to Fig. 1,2, the thermostatic type hatch machine comprises: a casing 1, in a plurality of egg unwheeling 2 transversely arranged casings 1, several fans 3 in a row are installed on the air intake end (porch of egg unwheeling 2) of casing 1, to egg unwheeling 2 forced air supplies.

Heating/the cooling device 5 that is used to heat or cools off air is located near casing 1 internal fan 3, and it comprises that being located at fan air draught place adds the heating tube 5A of hot-air and the cooling coil 5B of circulation cold water.

The air themperature control device comprises: the temperature sensor 4 that detects air themperature; Heating/cooling device is controlled by the temperature signal of temperature sensor 4, and the air that 3 pressures are sent here to fan heats or cools off; Make air themperature remain on the interior temperature setting device 6 of design temperature.

Temperature sensor is divided into master reference 4A and correcting sensor 4B, and master reference 4A is installed near air inlet place of egg unwheeling 2; Can detect the intake air temperature that flows into egg unwheeling 2; Correcting sensor 4B is installed in the exhaust side of egg unwheeling 2, and it can detect the recurrence temperature that egg unwheeling 2 exhausts are surveyed.Temperature is provided with 6 and revises the design temperature of master reference 4A according to the mensuration temperature signal of correcting sensor 4B.

For guaranteeing incubation rate, except that control temperature, also must adjust humidity and CO ₂Also comprise a humidity sensor 9 in the content, this device.

The airflow direction of this thermostatic type hatch machine is as shown in Figure 1: from left to right flow in the direction of arrows above the egg car, fall on the right side of casing, enter egg unwheeling 2 more from right to left, the air that comes out from egg unwheeling 2 is sucked by fan 3 once more and circulates then.Put a large amount of kind eggs for when hatching in the egg unwheeling 2 of discharging side by side in the hatch machine, also forming air channel.

During 5 work of heating/cooling device, except heating tube or water-cooled coil pipe, also can adopt the method for other heating or cooling, as can directly cold air being cooled off air in outside inspiration casing 1.The method that sucks cold air is as shown in Figure 1: the sky top portion of casing 1 has scavenge port 7, and the switching of scavenge port 7 and openings of sizes are realized by air door CD-ROM drive motor 8.

Heating/cooling device 5 is controlled by program setting (CPU).Establishing method is: control heating/cooling device 5 is controlled at identical value with the detected temperatures of master reference 4A with setting value, allows heating tube add hot-air when the mensuration temperature of master reference 4A is hanged down than setting value; Then the water-cooled coil pipe makes the force air cooling by cold water when the mensuration temperature of master reference 4A is higher than setting value.

The design temperature of master reference 4A is to adjust automatically according to the situation of kind of egg, and promptly the design temperature of master reference 4A is corrected the detected temperatures control of sensor 4B.Correcting sensor 4B is not directly used in detected temperatures control heating/cooling device 5, but revise the design temperature of master reference 4A earlier with the output signal of correcting sensor 4B, seetting program CPU controls heating-cooling device 5 then, and the detected temperatures that makes master reference 4A is with the design temperature unanimity.

Temperature setting device 6 is in the time of setting according to each time timer, proofreaies and correct the design temperature of a master reference 4A with the recurrence temperature of correcting sensor 4B mensuration.The setting-up time of time timer is to be proofreaied and correct factors calculating backs such as once required temperature amplitude, the time lag of heating cooling, egg-turning time to be determined by the design temperature of master reference 4A.

Simple method is: only detect the height of measured value and the setting value of correct detection 4B, do not calculate the temperature difference with design temperature.When the detected temperatures of correcting sensor 4B is higher than setting value, turn down the design temperature of master reference 4A with the temperature amplitude that configures; When the detected temperatures of correcting sensor 4B is lower than setting value, heighten the design temperature of master reference 4A with certain temperature amplitude.

Another kind of control method is: the mensuration temperature value of detection correcting sensor 4B and set temperature value is poor earlier, if the big more correction temperature amplitude of gap is big more.

Fig. 4 is a circuit diagram of the present utility model, and its working procedure is as follows: earlier air switch NF1-NF5 is all opened, open main switch CS1 then, send to control loop.When main switch CS1 closure, MC1 connects, fan 3 runnings.The light of CS2 control hatch machine.Master reference TEMP (4A), correcting sensor R-T (4B) and humidity sensor HUM (9) are connected in the input of control circuit board CPU (6).Master reference and correcting sensor have its actual temperature and design temperature respectively.

When the temperature that records when master reference is actual is higher than design temperature, correcting sensor is just turned down the design temperature of master reference, master reference oneself actual temperature and design temperature relatively then: (1) is when the actual temperature of master reference during greater than design temperature, CPU back as calculated outputs to the COOL refrigeration end by 32 pin, make the coil of magnetic valve SV connect water cooling tube work; (2) when the actual temperature of master reference during less than design temperature, to CN34 and AUX HEAT fire end, solid-state relay SSR conducting when CN34 has output makes main heating tube MAIN HEATER work to CPU through 21 pin output signals; Relay X3 coil has electricity when AUX HEAT end has output, makes the normal open switch closure of X3, and auxiliary heating tube AUX HEATER starts working.

When the temperature that records when correcting sensor is actual was lower than design temperature, correcting sensor was just heightened control hatch machine in back to the design temperature of master reference, and its control method is the same.

HUM is a humidity sensor 9, when actual humidity is lower than setting humidity, and 33 pin output signal conducting magnetic valve SV, humidifying system SPRAY work, until reaching desired moisture level, humidifying system quits work.
