Description

(5) INCUBATOR

one

The invention relates to poultry farming, in particular to small-capacity incubators, intended for use primarily in private farms.

A home incubator of small capacity is known, comprising a housing with supporting elements, an egg tray installed in it, a temperature and humidity control unit, and an egg rotation mechanism t.0.

Turning and c in the incubator takes place either manually or mechanically, which is laborious and energy intensive.

An incubator is also known, which includes a housing with supporting elements, an egg tray installed in it, a temperature and humidity control unit, and an egg turning mechanism. The mechanism for rotating an egg contains an electric motor, a gearbox, on the output shaft of which a rotary lever is installed, transmitting movement through a system of levers to a movable grid by means of which the eggs are rotated 2.

The disadvantage of this incubator is the high energy intensity of the egg turning process.

The purpose of the invention is to reduce the energy intensity of the process of rotating the eggs.

This goal is achieved by the fact that the mechanism of rotation of the eggs is made in the form of two fixed on the side

10 walls of the body of tanks with drain valves connected by means of nozzles with funnels placed in the upper part of the body, alternately interacting with the water supply

ts nozzle, and the supporting elements of the body are made in the form of prisms vertically fixed along its center, mounted with the possibility of rotation in the vertical plane on the reference

20 cooker.

Figure 1 shows a longitudinal section of the incubator; figure 2 is a top view of the incubator; on fig.Z - tray 3 side view; Fig. 4 shows the ends of the incubator when turning to the left, rear view. The incubator consists of a housing 1 in which a wire tray 2 for eggs is installed, a temperature and humidity control unit including a temperature sensor 3, if heating elements and a tank 5 to humidify the air. The incubator rotation mechanism in the incubator is made in the form of two tanks 6 fixed to the side walls of the housing 1 with drain valves 7. connected by means of nozzles 8, with funnels 9 placed in the upper part of the body 1 and tightly attached to it with the water outlet pipe 10 equipped with an adjusting valve 11 and connected to the tank 12. The supporting elements of the body are made in the form of prisms 13, rigidly fixed at the bottom of the latter and vertically mounted on the base plate with the possibility of rotation in the vertical direction cial plane. To regulate the air exchange in the upper and lower parts of the incubator, the holes 15 and 16 are made with the flaps 17 and 18. The tank 6 is freed from water along the discharge chute 19. At the bottom of the case, the limiters 20 of the incubator rotation are located. To rotate the eggs in the incubator, the adjusting valve 11 of the water supply nozzle 10 is opened, the water from the tank 12 enters one of the funnels 9, namely, the funnel that is currently connected to the nozzle 8 and the tank 6 in the upper position. As the tank is filled with water, the tilting moment grows and the whole incubator turns on prisms 13 towards the filled tank 6. At the same time, the second funnel fits under the water inlet 10 with the adjusting valve 11 and the water begins to flow into the tank in its upper position. The tank filled with water lowers and simultaneously presses valve 7 to the bottom of chute 19, opening the drain hole. The water enters the chute in the drain tank, not shown in the drawing. 1 Thus, when water enters one tank, it is poured from another. The cycles are repeated as long as there is water in the tank 12. About 600 g of water are consumed per turn of the incubator with a capacity of 50 chicken eggs. To automatically turn the incubator for 8 hours, a 5 L tank is required with a turning frequency once per hour. By adjusting the flow rate of the water to the funnels 9, the eggs are rotated in the desired cycle. Together with the incubator, the tray is rotated, and the eggs roll along the Guides of the tray to a distance equal to half the length of the circumference of the small diameter of the eggs, which ensures that the eggs turn to iBo and correspond to the required incubation mode. This small capacity incubator with automatic egg rotation allows mechanization of the incubation process in personal facilities. Claims of the invention Incubator, including a housing with supporting elements fixed at its bottom, is installed, J has a tray for eggs in it, a temperature and humidity control unit and an egg turning mechanism, characterized in that, in order to reduce the energy consumption of the egg turning process, the egg rotates made in the form of two tanks fixed to the side walls of the tank casing with drain valves connected via branch pipes with funnels placed in the upper part of the casing, alternately interacting with the water supply pipe room, and the supporting elements of the body are made in the form of vertically fixed in its center pr.zm installed with the possibility of rotation in a vertical plane on the base plate.
