Description

The temperature automatically controlled birds hatching box of a kind of coal stove

The utility model relates to aquaculture and incubates the fowl technology.More particularly, be a kind of be the birds hatching box of heater with the coal stove.

In the patent No. is 94222606.2 utility model patent specification, as the patentee, I disclose the practical technique that a kind of name is called " incubating fowl coal stove automatic temperature control device ", this thermostat is in incubator box top cover inboard the intensification sensor to be set, place coal stove in the incubator box, intensification control circuit and actuating motor are set simultaneously, and under the control of intensification control circuit, open and close the movable air door of coal stove by actuating motor, open air door and heat up, close air door and promptly stop to heat up.But, there is such problem in actual the use, in sternly hot summer or hatching later stage, because environmental temperature is too high, or hatching later stage kind egg self generation heat, make the interior temperature of incubator box surpass the incubation temperature scope.Cause embryonic death for fear of temperature is too high, guarantee chickling-surviving rate, must manually in time lower the temperature incubator box, this artificial cool egg mode, not only time-consuming, and be difficult to hold optimum temperature, chickling-surviving rate is subjected to bigger influence.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a kind of temperature automatically controlled birds hatching box of coal stove with automatic cooling control function is provided.Incubate the fowl chickling-surviving rate with raising, alleviate labor intensity of operating staff.

The purpose of this utility model is achieved through the following technical solutions.

The utility model comprises casing, intensification coal stove and intensification controller, and described intensification controller is by the intensification sensor Rt1, intensification control circuit, the actuating motor M1 that are arranged on casing top cover inboard, and the movable air door that is opened and closed by actuating motor M1 control constitutes.

Architectural feature of the present utility model is:

A., the cooling controller that is made of cooling sensor Rt2, cooling control circuit and actuating motor M2, M3 is set simultaneously, its cooling sensor Rt2 is arranged on casing top cover inboard, and exhaust fan and the loose-leaf fan door of being controlled respectively by actuating motor M2, M3 is installed at wall box; Described cooling control circuit is made of comparator IC3, IC4, switch triode BG4, BG5 and combination switch pipe T3, T4, sensor Rt2 is arranged on the positive input of comparator IC3, at triode BG5 colelctor electrode, serial connection relay J 1 coil, its normally opened contact is serially connected in the electric power loop of actuating motor M2, described actuating motor M3 is a direct current generator, is arranged in multiple tube T3, the T4 output loop;

B. described intensification control circuit is made of comparator IC1, IC2, switch triode BG2 and multiple tube T1, T2, and sensor Rt1 is arranged on the positive input of comparator IC1, and actuating motor M1 is a direct current generator, is arranged in multiple tube T1, the T2 output loop.

Compared with the prior art, the utility model no matter be under higher environmental temperature, still in the hatching later stage, when planting the egg self-heating, does not need to carry out artificial cool egg owing to simultaneously the cooling controller is set.Cooling sensor Rt2 detects the temperature in the incubator box timely and accurately, by the cooling control circuit, output signal to actuating motor M2 and M3, finally, control is installed in exhaust fan and the loose-leaf fan door on the wall box, make that when hatching the temperature inside the box surpasses setting value actuating motor is opened exhaust fan and loose-leaf fan door automatically, carries out cool egg; And in the temperature inside the box is reduced to setting range the time, automatically exhaust fan and loose-leaf fan door are closed heavily again, implement insulation.Cooling control circuit in the utility model and simple in structure, the reliable operation of intensification control circuit.Use the utility model can improve hatching quality significantly, improve chickling-surviving rate.

By the following examples, in conjunction with the accompanying drawings, the utility model is further described.

Embodiment:

Present embodiment is the improvement to 94222606.2 utility model patents.

As shown in Figure 1, adopt casing 1 and intensification coal stove 2 in 94222606.2 utility model patents.Intensification sensor Rt1 4 and cooling sensor Rt2 5 are set in casing 1 top cover inboard, exhaust fan 6 and loose-leaf fan door 7 are installed at casing 1 sidewall.The movable air door 3 of coal stove 2 is opened and closed by actuating motor M1 control, and exhaust fan 6 and loose-leaf fan door 7 are controlled by actuating motor M2 and actuating motor M3 respectively.

Intensification control circuit structure in the present embodiment as shown in Figure 2.Be made of comparator IC1, IC2, switch triode BG2 and multiple tube T1, T2, sensor Rt1 is arranged on the positive input of comparator IC1, and actuating motor M1 is a direct current generator, is arranged in multiple tube T1, the T2 output loop.

As shown in Figure 3, cooling control circuit in the present embodiment is made of comparator IC3, IC4, switch triode BG4, BG5 and combination switch pipe T3, T4, sensor Rt2 is arranged on the positive input of comparator IC3, at triode BG5 colelctor electrode, serial connection relay J 1 coil, its normally opened contact is serially connected in the electric power loop of actuating motor M2, and described actuating motor M3 is a direct current generator, is arranged in multiple tube T3, the T4 output loop;

As shown in the figure, employing has the sensor (comprising intensification sensor Rt1 and cooling sensor Rt2) of negative temperature coefficient, temperature in casing is lower than the temperature required value of hatching, because sensor Rt1 resistance increases, comparator IC1 exports high level, comparator IC2 also exports high level thereupon, switch triode BG2 conducting, multiple tube T2 conducting, motor M 1 is just being changeed, thereby drive activity air door 3 is opened, for heating up in the casing.When temperature reaches required scope in the casing and since sensor Rt1 resistance reduce comparator IC1 output low level, IC2 is output low level thereupon also, and switch triode BG2 ends, multiple tube T1 conducting, motor M 1 counter-rotating, thus drive activity air door 3 close, stop to heat up.When in case temperature surpasses certain setting value in the casing, because reducing of Rt2 resistance, operational amplifier IC3 output low level signal, the also defeated thereupon low level signal of comparator IC4, triode BG4 ends, the BG5 conducting, relay J 1 coil gets, its normally opened contact is closed thereupon, and actuating motor M1 power supply is switched on, and exhaust fan is started.Simultaneously, owing to ending of triode BG4, multiple tube T3 conducting, and multiple tube T4 ends, and actuating motor M3 backward rotation is opened loose-leaf fan door, and the beginning air draft is lowered the temperature.Otherwise, when the temperature in the casing is reduced to setting range, because the increase of sensor Rt2 resistance, operational amplifier IC3 exports high level signal, the also defeated thereupon high level signal of IC4, triode BG4 conducting, triode BG5 ends, relay J 1 coil losing electricity, and its normally opened contact is opened thereupon, actuating motor M2 power supply is cut off, and exhaust fan stops operating.Simultaneously, because the conducting of triode BG4, multiple tube T3 ends, and multiple tube T4 conducting, actuating motor M3 forward rotation is closed loose-leaf fan door.

Capacitor C 3, C4 and 2 C3 and 3C4 form the impulse electricity impulse circuit respectively among Fig. 2 and Fig. 3, in order to economize on electricity.

Resistance 2R12 shown in Fig. 3 is the base biasing resistor of triode BG5, form step-down rectifying circuit by diode 2D2,2D3 and transformer B, wherein 2D2 is an isolating diode, when AC-powered stops, automatically convert direct current supply to, Ec is a dc source among the figure.
