Incubator with your hands - is beneficial, simple, practical

In our difficult time, when the prices of goods are rising unrelenting pace, you will always find an area in which to profitably apply their practical skills and theoretical knowledge. Looking at the costs incubator produced in industrial conditions, one can easily calculate the benefit of independent manufacturing such a device. Especially that produce homemade incubator with his own hands is not so difficult.

In short: an incubator for 60-70 eggs, mechanical coup with a special grille, does not automatically make fundamentally. Heating by means of bulbs, two chains. Temperature monitoring via electrical contact thermometer. Electronics do not trust. Run temperature by 0.5 degree angles. Cheap and cheerful. In the presence of components can be manufactured incubator for 3 - 4 hr. The most important thing in making - provide ability to maintain optimal performance and humidity the temperature inside the device, as well as to create conditions for the timely eggs coup with the aim of their uniform warming.

housing incubator

most improvised devices everything is based on the body. And the incubator in this case is no exception.

In the manufacture of the body, particular attention should be paid to ensuring good thermal insulation for future devices. This will allow in the future to avoid the trouble of complying with strict temperature control in the incubation chamber.

For the manufacture of the housing should be fine porous polymeric materials penoplex (polystyrene) 20 mm thick, etc. You can also use sheets of fiberboard or particleboard, but should create double walls filled with foam, felt or foam.

The dimensions of the incubator will be directly dependent on the number of eggs, which is planned to be placed in the chamber at the same time. The height of the inner chamber of 50 cm would be sufficient. The area of ​​the internal base will be equal to the square of the tray for eggs. But it is necessary to add about 50 mm on each side. Such clearance should be between the tray and the housing of the incubator for the circulation of air flows. The lower base of the incubator is required to drill a plurality of apertures 10 mm in diameter, through which will carried breathability between the interior space of the chamber and the external environment (incubator must constantly enriched oxygen). For incubator for 50 eggs enough to 6 holes.

Attention! Lower openings should be positioned so that they do not overlap baking tray (tray) with water that will be installed in the chamber to maintain sufficient humidity.

To ensure smooth air flow between the bottom of the device and the surface on which it is installed, it must be a gap of 30... 50 mm. In the top cover should be made sightglass 100x100 mm glass closable. If the incubator is no forced ventilation, the glass during operation should be slightly open, leaving a gap size of 10... 15 mm.

Tray Incubator

To eggs can be neatly tucked away in the interior of the incubator, we need to make a special tray. In this case, it can be made based on the wooden box, which bottom is covered with fine mesh. As the grid is suitable for both ordinary moskitka used in the design of modern window of glass, and metal (may be different) mesh having a mesh size comparable to the size of 5x5 mm (but not more). In order to avoid sagging nets, bottom tray can nail down a couple of small rods, which comprehensively strengthen the construction of the tray.

To the eggs during incubation it easier to turn the tray should be equipped with plug-in wooden lattice. For convenience, you can make several arrays having different sizes of the internal cells. So, for the quail eggs fit grille to the size 45h35 mm mesh, to egg the right size 67h75 mm mesh. If you want to lay in the incubator goose eggs, and then the cells must be of appropriate size - 90x60 mm. By width of the lattice should be less than 5 mm of the tray. In length it should be less than 50... 60 mm - for quail, 80... 90 mm - for chicken and 100... 110 mm - for goose eggs. Thus, moving the bars along the tray, you can turn the eggs 180 degrees. For the purpose of uniform heating of the eggs over time to perform such a procedure should be about once per 2 - 3 h.

The height of the flanges of the tray should be 70-80 mm. The tray should be mounted on legs 100 mm.

This is the most simple tray design that allows you to turn all their eggs at once. But in order to incubator design it was more modern, egg flipping process can be automated. And it will take to make some technical improvements.

How to make a revolution in the incubator

In order to automate the process of the eggs in the incubator coup in its design to be implemented electromechanical drive which is triggered after a certain period of time (as we have said, he is 2-3 hours). The accuracy of the time interval will provide a special timer. The relay can be purchased ready-made. Fans of "dig deeper" in the chips can do it yourself, taking as a basis for electronic or mechanical watches, which are easy to buy, and in Moscow, and in every village.

Here is what writes on this subject FORUMHOUSE user.

mednagolov (Member FORUMHOUSE):

Now on sale is easy to buy Chinese electromechanical relays with 24-hour cycle. In fact - this is the basic clock with a plug that plugs into the socket, and on the case of this watch has a socket into which the consumer is stuck inside the clock turns tiddly electric motor. do not need to start them in a circle of the dial, lined for 24 hours, are "nazhimalki", which expose intervals. The motor must necessarily transmit torque through the gearbox. This will help make the move smoother grille and keep the egg intact.

Tray grid should move along the guide rails. The role of the guide will be able to play the tray. But in order to avoid accidental jamming of the mechanism can be improved. For this purpose along the center axis of the lattice should be attached protruding from two ends of the metal shaft. She will play the role of a reliable guide. Axis will be inserted in special grooves formed on the edge of the tray. This design is reliable, it can be easily assemble and disassemble quickly if necessary.

In order to drive the grate with eggs, we need a reciprocating mechanism, consisting of an electric motor, gearbox, crank mechanism and the rod connecting the drive with a lattice tray.

As an electric motor can be used special "motors" for microwaves, which are commercially available. Also, some artisans create an electromechanical actuator based on a mechanism which is part of the janitors automobile. Or, a way out of the situation came up forumchanin mednagolov: the drive mechanism turning eggs by e-mail. Engine ball remote crane d = 3/4 220v (has extremely strong and durable reduction gear, and the end position switches).

The power supply, he used the old computer, and time switches - mechanism of Chinese hours, which was written just above.
The mechanism operates as follows: the relay closes the circuit at a predetermined time interval. The mechanism is set in motion and moves the grill pan, turning the eggs. Then trigger limit switches (limit switches), and the grid is fixed at the opposite extreme position. After a predetermined time the cycle repeats and the grating returns to its original position. The entire process takes place in the home-made without human intervention.

heated incubator

Proper placement of the heating elements in the chamber of the incubator - it is the key to success, ensuring the withdrawal of healthy and strong chicks. As the heating elements common to use ordinary incandescent bulbs. Ideally they are best installed over the tray with the eggs, placing the incubator evenly over the perimeter. The tray and the heating element must share at least a distance of 25 cm. In homemade incubator use low power light bulbs, 25 Watts, etc. The total capacity of the heating elements used in such an incubator should be 80 watts - to device capable of simultaneous output 50 chicks.

The smaller the power of the heating elements, the more uniform heat distribution takes place in the incubation chamber.

By placing lights on the walls of the chamber, should also monitor their evenly spaced around the perimeter. Be aware that using a serial electrical connection of the heating elements can significantly prolong their service life. But the power of each customer, in this case reduced by half. This should be considered when calculating the number of heating elements, because an appropriate connection method number of users should be double.

Control of the temperature display

As we already know, in the incubator chamber temperature must exactly match the specified parameters. Otherwise - worthless such a device. The optimal hatching in vitro is a temperature from 37.5 to 38,3º C. But it should strictly abide by. Maintain the specified range will help ordinary thermostat, which is no problem you can buy in the store. It is necessary that the device provides precision temperature values ​​corresponding 0,2º C. The error represented by larger values ​​may be detrimental to the developing embryos.

Connect the thermostat to the heating elements to the person who decided to make their own hands incubator, we think there is no trouble. The main thing to see to it that the temperature sensor is located near the tray of eggs. For a more accurate sensor readings can even be mounted on the tray. The thermometer should be used as an additional normal controls. It is better if it is electronic, capable of displaying tenths of a degree. But in extreme cases, fit and regular alcohol thermometer. Hooking in the chamber should be such that it is positioned directly above the tray. In this case, his testimony can shoot while looking through the sight glass.

heat accumulator

_JG_ (participant FORUMHOUSE):

Slowly lower the temperature, it is necessary to use a thermal battery. I'm in the TA as the water used. It gives moisture and even gaining the temperature, and when it is turned off for a long time gives, not allowing the temperature to fall rapidly. Only a container of water should be big. You can just fucking metal dumbbell or put inside - is not a TA?

It remains to add that without a humidifier in the incubator all your efforts are doomed to failure. Therefore, an open pan or bowl filled with water, can be regarded as one of the essential elements participating in the process of incubation. As for the heat accumulator, the water bottle or a plastic bottle of water will never be superfluous in the interior of your incubator.

Control of humidity can be performed by psychrometer, which can be purchased at the store household goods. The optimum humidity in the incubator should conform to the figures 50-55% (immediately before output chicks can be increased up to values ​​of 65-70%).

Ventilation incubator

Many owners of home-made incubators considered that the fan is an integral part of such a device. But practice shows that small incubator, the number of eggs in which no more than 50 pcs., Can do without mechanical ventilation. Convection of air in it occurs naturally, and it is enough to maintain the vital germs.

If your camera incubator is designed for large number of eggs, or if you want in whatever was to create an ideal microclimate in the device for these purposes may be used a specially designed fan diameter from 80 to 200 mm (depending on the volume of the chamber).

The fan can be built into the top cover of the incubator in such a way that it draws air from the inner chamber. Part of the air flow will go out, and most of its volume will be reflected from the cover and held above the lower air-supply holes, mixing warm air and cold enriching it oxygen.

Here, perhaps, and all.
