Description

The utility model relates to the field of agriculture.

The utility model is designed to improve the results of artificial incubation of bird eggs.

The uniformity of air temperature throughout the chamber is one of the important characteristics of the bird egg incubator. Ensuring uniform heating of all eggs during incubation narrows the hatch window and allows more accurate implementation of the temperature regimes necessary for the normal development of embryos [1,2,4].

To evenly distribute the air heated by the heating elements in the incubator, internal fans are used. However, the presence of fluff from hatching chicks has a negative impact on the operation of electric motors and heating elements, which reduces the uniformity of temperature in the internal volume of the incubator. To remove fluff from the air, various technical solutions are used.

Known "Incubator hatcher" (patent SU 1395239 A1 dated May 15, 1988), containing a housing, on the rear wall of which there are humidifier glass panels (SPU), a fan and an electric heating element. Above the SPU there is a water distributor, and under the SPU there is a gutter for water flow in the form of a radial groove with a drain hole. During the operation of the incubator, water from the distributor is evenly supplied to the surface of the SPU. Fluff from chickens, moved through the chamber by the air flow from the fan, settles on the surface of the SPU and is washed off by the water flow into the gutter. From the gutter, through the outlet, water, together with fluff, is removed from the chamber into the sewer.

The disadvantages of this hatcher are: the inability to adjust the humidity in the chamber, due to the constant flow of water, high water consumption, the need to install a system for cleaning water from fluff before being discharged into the sewer.

Known incubators and hatchers company HatchTech, equipped with cyclone air filters to remove fluff [2].

The disadvantage of using cyclone filters is the need to connect additional equipment to the incubator and high power consumption.

Known incubators and hatchers, equipped with a fluffy corridor, which is a room connected by a duct with the internal volume of the hatcher. Due to the creation of a weak rarefaction of air in the down corridor due to the operation of fans, air with fluff enters the down corridor, however, due to the low air velocity in the down corridor, the fluff is not thrown out of the down corridor, but settles on the floor [3].

The disadvantage of using down corridors is the need for additional space for their placement, complicated fan settings, and additional power consumption.

The Grumbach universal incubator was chosen as a prototype, in the upper part of the hatching chamber of which a fabric filter is provided on a frame installed in the grooves of the body, which prevents fluff from getting into the fan and the heating element installed directly behind the fan. The disadvantage of the described incubator is a gradual decrease in speed air exchange in the incubator chamber in the process of hatching young animals by reducing the throughput of the filter caused by the sticking of fluff. The filter requires regular cleaning, however, in case of mass removal, a large amount of fluff clogs the filter until the air exchange stops completely, which causes the emergency shutdown system of the heating element to operate [5].

The technical result consists in increasing the uniformity of air temperature throughout the entire internal volume of the hatcher for bird eggs.

The technical result is achieved in that the hatcher for bird eggs, containing a body, a heating element, a fan, an air humidification system, a main temperature sensor, egg trays, a tray rotation mechanism and an incubator control unit with a screen and an alarm, characterized in that additional temperature sensors are equipped with a supply of cables that allow them to be installed anywhere in the incubator, the incubator control unit records the temperature difference of additional temperature sensors, the fan speed is automatically adjusted based on data on the temperature difference of additional temperature sensors.

The value of the temperature difference of additional temperature sensors is displayed on the screen of the incubator control unit.

The screen of the incubator control unit displays information about the fan speed.

The alarm signaling of the incubator control unit takes into account the data on the temperature difference of additional temperature sensors.

In FIG. 1 shows a drawing of the incubator.

The incubator contains a body 1, egg trays 2, a tray rotation mechanism 3, a heating element 4, a fan 5, an air filter 6, an air humidification system 7, a main temperature sensor 8, additional temperature sensors 9, a control unit 10, a control unit screen 11.

The incubator is used as follows. Prior to incubation of bird eggs, egg trays 2 and filter 6 are removed from the body of the incubator 1. Additional temperature sensors 9 are moved to the main temperature sensor 8 using the supply of wires 14. The incubator is turned on. After the readings of all temperature sensors are stabilized, additional temperature sensors 9 are calibrated according to the temperature value of the main temperature sensor 8. The incubator is turned off, additional temperature sensors 9 and filter 6 are installed in their regular places, egg trays 2 are installed and filled with eggs 12. Incubator include. The control unit 10, controlling the operation of the heating element 4, the humidification system 7 and the mechanism for turning the trays 3, will maintain pre-set conditions in the incubator. After the start of hatching of young animals from eggs 12, together with the air flow 13 in the body 1 of the incubator, fluff will begin to circulate, which will settle on the filter 6, which will cause a decrease in the throughput of the filter 6, and, as a result, the air flow rate 13 will decrease, and the readings of additional temperature sensors 9 will begin to differ from each other, which is a signal for the control unit 10 to increase the fan speed. An increase in the air flow rate 13 compensates for the thermal gradient in the housing 1. As the filter 6 becomes further clogged, the control unit 1 will bring the fan 5 to the maximum mode, and further compensation of the thermal gradient will become impossible. The control unit 10 will turn on the alarm, and the value of the temperature difference of the additional temperature sensors 9 will be displayed on the screen 11 of the control unit 10, which will allow the maintenance personnel to clean the filter 6 in a timely manner. assess the degree of contamination of filters 6 and predict the frequency of their cleaning, which allows maintaining a uniform temperature in the incubator chamber throughout the incubation and hatching of young birds from eggs.
