Hereinafter, an egg hatching machine according to an embodiment of the present invention will be described with reference to the drawings. However, the embodiment shown below is an egg hatching machine exemplified by embodying the technical idea of the present invention, and the present invention is not limited to the egg hatching machine described below. Specifically, the components indicated by the scope of the patent application are not specifically the components of the embodiments. In particular, the dimensions, materials, shapes, relative arrangements, and the like of the constituent members described in the embodiments are not intended to limit the scope of the invention, and are merely illustrative examples. Furthermore, the size, positional relationship, and the like of the members shown in the respective drawings are exaggerated for the sake of clarity. In the following description, the same names and symbols denote the same or the same components, and the detailed description is omitted as appropriate. Further, each of the elements constituting the present invention may be configured such that a plurality of elements are formed by the same member and a plurality of elements are used as one type of member, and conversely, a function of realizing one type of member may be shared by a plurality of members. Further, some of the embodiments and the contents described in the embodiments may be used in other embodiments, embodiments, and the like.

In the present embodiment, a case where a single egg hatching machine is applied to the present invention will be described. Fig. 1 is a vertical sectional view of the egg hatching machine of the embodiment. Fig. 2 is a front elevational view of the egg hatching machine of the present embodiment, with the top of the outer casing removed.

The hatcher 1 includes an outer casing 5, a blower 10, a cooling means 20, a heating means 22, a frame unit 30, and a partition plate 40. The outer casing 5 is a rectangular parallelepiped box and is sealed inside, and the blower 10, the cooling means 20, the heating means 22, the frame unit 30, and the partition plate 40 are provided in the outer casing 5. The air passage 6 is formed in a central portion in which the inside of the casing 5 is divided into two halves, and the frame unit 30 is disposed in a divided region which is divided into two sides by the air passage 6 .

Five blowers 10 are arranged in series on the floor of the air supply passage 6, and the wind is generated upward. Moreover, the number of blowers is not limited to five, and it is possible to set four or less or six or more according to the required air volume, and this need not be explained. The blower 10 includes a fan 11 having a rotary vane 12 and a motor 13, a fixed vane 15 for rectifying the wind generated by the fan 11, and a casing 17 for supporting the fan 11 and the fixed vane 15.

Viewed from above, the rotating blades 12 of the fan 11 are rotated clockwise by the rotational power of the motor 13, and the wind is generated upward. At this time, the rising wind from the fan 11 does not blow straight up, but spirals in a clockwise manner. Of course, the rotary vane 12 can also be rotated counterclockwise. At this time, the mounting method of the blade is opposite to the legend.

The fixed vane 15 radially extends around the rotating shaft 131 of the rotating vane 12 and has a fixed fin portion 16 disposed adjacent to the rotating vane 12 directly above. The number of fins 16 herein is preferably set to be not a multiple of the rotating blades 12. If the number of rotations of the blades is multiplied, the number of times or the number of times when the plurality of rotating blades and the fins coincide with each other increases, and the amount of wind is reduced. Thus, the number of fins is intentionally made different from the multiple of the rotating blades. In the example of Fig. 5, the fins are not eight in multiple but nine in the four rotating blades 12. On the other hand, solid The fixed blade 15 has a function of raising the wind that is raised by the fan 11 to rise in the vertical direction. The more detailed structure and function of the blower 10 will be described later.

In the casing 5, in order to adjust the temperature of the air supplied to the fan 11, the cooling means 20 and the heating means 22 are provided. The cooling means 20 is supported by the frame 17 of each blower 10 and is disposed below the fan 11. The cooling means 20 is provided with a cooler 24 that cools the air passing through the apparatus section. As the cooler 24, for example, a heat exchanger that circulates cooling water in a loop shape can be used.

Further, the heating means 22 is disposed on the air circulation path circulating by the fan 11 for adjusting the temperature of the circulating air. In the example shown in the cross-sectional view of Fig. 1, it is fixed to the top of the casing 5 to heat the air which is raised by the air passage 6. As the heater 22, for example, an electric heater of a heating element can be used.

Further, in the casing 5, a temperature sensor 50 for measuring the internal temperature is provided, and the cooling means 20 or the heating means 22 can be controlled based on the measured value of the temperature sensor 50. Further, the temperature sensor is not only the temperature sensor 50 for measuring the internal temperature of the casing 5, but also the second temperature sensor 52 for measuring the temperature of the air passing through the frame unit 30, or according to these dual systems. The measured value of the temperature sensor is controlled by the cooling means 20 or the heating means 22. In the example of Fig. 1, the temperature sensor 50 that detects the indoor temperature is fixed to the top of the casing 5. The second temperature sensor 52 is provided, for example, at the lower end of the partition plate 40-2. The measured values of these temperature sensors 50 or second temperature sensors 52 are used to control the overall temperature of the room. Specifically, the cooling means 20 or the heating means 22 are transported For example, the indoor temperature is controlled to a constant value above and below 37 °C. In particular, as the amount of heat emitted by the egg such as the fertilization rate of the egg or the size of the egg changes, the second temperature sensor 52 detects the actual temperature including the heat generated by the egg, and cools according to this point. The ability to adjust or adjust the degree of heating for feedback control allows for optimum temperature management in response to the actual temperature inside the enclosure 5. Further, the temperature sensor 50 or the second temperature sensor 52 is not limited to only one, and a plurality of the temperature sensors 50 may be provided. Furthermore, it is also possible to configure only one of the temperature sensor or the second temperature sensor.

The frame unit 30 has a function of multiplying and placing an egg shed of a majority of eggs, and two sets are provided on both sides of the air supply passage 6, and a total of four first to fourth frame units 30-1 to 30-4 are provided. Further, the number of frame units is four in the example of Fig. 2, but the present invention is not limited to this configuration, and it is of course possible to provide three or less or five or more. For example, as shown in Fig. 6, the frame unit 30' is provided in a variation of six units using 30'-1, 30'-2, 30'-3, 30'-4, 30'-5, and 30'-6. Hatching machine 1B.

The frame unit 30 is provided with a plurality of multi-layer tray sheds 31 and casters 36 disposed below, and the casters 36 are movable on the floor. In this example, the casters 36 are moved along the pre-layed track.

The multi-layer tray shed 31 includes a plurality of trays 33 for vertically accommodating a plurality of eggs, and a support frame 32 for holding the multi-layer trays 33. On each of the multi-layer tray sheds 31, as shown in Fig. 1, the 15-layer tray 33 is inclined to form a transferable egg.

The compartment plate 40 is a blower 10 with the frame unit 30 The side surface of the side is opposed to the flat plate at the boundary between the air supply passage 6 and the frame unit 30, and shields the wind from moving between the air supply passage 6 and the frame unit. The partition plate 40 is provided so as to extend over the air supply passage 6 so as to extend over the entire area of the frame unit 30 on which the eggs are placed, and one of the two sides of the air supply path 6 is provided, and a total of two pieces of the partition plate 40 are provided. 1, 40-2.

Specifically, the partition plate 40 is formed so as to cover the side surface of the air supply passage 6 of the multi-layer pallet shed 31 for placing the eggs, and is fixedly disposed on the casing 17 of the air blower 10, and in the height direction, as in the first As shown in Fig. 1, it extends from the vicinity of the lower end of the multi-layer pallet shed 31 to the vicinity of the upper end. Further, in the horizontal direction, as shown in Fig. 2, the partition plate 40-1 extends from one end (lower end in the drawing) of the multi-layer tray shed 31 provided with the first frame unit 30-1 to the second frame. The other end of the multi-layer tray shed 31 of the unit 30-2 (upper end in the drawing).

Here, the partition plate extends in the height direction and the upper end extends to the tray provided in the uppermost layer. On the other side, the lower end extends to the tray set at the bottom of the frame unit. However, the lower end side of the partition plate does not necessarily need to completely cover the lowermost layer of the frame unit, and may have a slight gap. In other words, the lower end of the partition plate can also be extended to a position away from the lowermost layer of the frame unit to constitute the compartment plate shorter. This expands the opening and allows the wind to flow more easily.

By providing the partition plate 40 of this structure at the boundary between the air supply passage 6 and the side frame units 30, the side surfaces of the air supply passage 6 and the frame unit 30 can be shielded, and the wind can be blocked. Thereby, from the fan 11 upwards The wind blown out by the square diffusion does not intrude into the frame unit 30 from the side, but rises all the way to the uppermost portion of the air supply passage 6, and is divided into left and right along the ceiling of the outer casing 5, and thereafter, only invades the frame unit 30 from above. . Further, the wind blown from the inside of the frame unit 30 to the outside does not pass through the side of the frame unit 30.

If the wind also invades from the side of the frame unit 30, the wind from the side and the wind from the upper side are different in temperature. Therefore, in the frame unit 30, there is also a temperature difference due to the place in the vertical direction and the horizontal direction. doubt.

On the other hand, as described in the present embodiment, when the wind only intrudes into the frame unit 30 from above, and only passes through from below, only wind of substantially the same temperature intrudes into the frame unit 30, and the vertical inside the frame unit 30 can be Temperature and directional unevenness in the horizontal direction are suppressed to a minimum.

As mentioned above, the eggs hatch within 21 days. If the average temperature difference between the places where the eggs are placed is 0.1 °C, the time required for hatching will be several hours. Therefore, if the temperature in the frame unit 30 is uneven due to the place, even if the eggs placed in the same frame unit 30 have a large difference in the time required for hatching, efficient work cannot be performed. On the other hand, by providing the partition plate 40, temperature unevenness in the vertical direction in the frame unit 30 can be suppressed, and the time difference of hatching chicks can be minimized, whereby the quality of the chicken can be greatly improved.

Next, the fixed blade 15 will be described in detail with reference to FIGS. 3 to 5. Figure 3 is a front view of the fixed blade. Figure 4 is a diagram showing the structure of the fin of the fixed blade, and Figure 4A is the plane of the fin. A side view seen from the vertical direction (fan rotation direction), and Fig. 4B is a side view seen from the outer side (outer tube side) of the fin. Figure 5 is a front view of the fixed vane and fan.

The fixed vane 15 includes a shaft cylinder 151, an outer cylinder 152, and nine fin portions 16 that extend between the coupling shaft cylinder 151 and the outer cylinder 152. As shown in FIG. 4, the fin portion 16 has a curved portion 162 in which a substantially rectangular flat plate is formed and the lower side half is bent toward the one side side. The direction in which the curved portion 162 of the fin portion 16 is bent is a direction opposite to the rotation direction (clockwise) of the rotary vane 12 of the fan 11 (counterclockwise).

Further, the fin portion 16 is formed such that the width of the fin portion 16 is widened as it approaches the outer end 162 connected to the outer tube 152, and the lower end side is gradually expanded.

The shaft cylinder 151 has the same axial center as the rotating shaft 131 of the fan 11, and a cavity is formed inside. The nine fins 16 extend radially around the barrel 151 at an interval of 40° to the outer cylinder 152. Further, the fan 11 provided below the fixed blade 15 has the rotary blades 12 of four blades provided at intervals of 90° around the rotary shaft 131. By changing the number of fins or blades, of course, the angle will also change. For example, if five blades are provided on the rotary vane 12, the interval is 72°.

In such a configuration, the rotating blades 12 of the fan 11 are seen from above, and if rotated clockwise, a gas flow in which the clockwise vortex diffuses and rises is generated. At this time, since the rotary blades 12 of the fan 11 are composed of four blades, the airflow generated by the rotation of the rotary blades 12 causes the wind speed to be uneven due to the place in the horizontal direction.

If the wind with an uneven wind speed enters the frame unit 30 from above, as shown in Fig. 2, an uneven temperature is generated in the horizontal plane. When the temperature in the horizontal direction is not uniform, the time required for the hatching of the eggs will be different as described above.

On the other hand, in the embodiment in which the fixed vane 15 is provided, the wind generated from the fan 11 passes directly through the fixed vane 15, but at this time, the wind is formed on the lower side of the rotary vane 12 side of the fin portion 16, counterclockwise The curved portion 161 that is curved on the rotating side is blocked, and is rectified along the surface of the fin portion 11 so as not to rise obliquely upward but to rise more vertically. Further, when the rotary vane 12 is rotated counterclockwise, the curved direction of the curved portion 161 also forms a clockwise side in the opposite direction, which need not be described.

Further, the number (9) of the fins 16 of the fixed vane 15 is larger than the number of vanes (four) of the rotating vane 12, and is disposed at intervals of 40° on the periphery of the rotating shaft 131, so that the rotating vane is disposed. The unevenness of the wind speed generated by 12 is greatly suppressed, and the air supply can be more evenly dispersed.

Although the structure of the egg hatching machine 1 of the present embodiment has been described in detail above, according to the present embodiment, the partition plate 40 is provided on both sides of the air supply passage 6 in which the air blower 10 is provided, by shielding the air supply passage 6 and The frame unit 30 prevents wind from entering the frame unit 30 from the side, and makes the temperature environment in the vertical direction of the frame unit 30 more uniform.

Further, in the present embodiment, the fixed vane 15 is provided above the fan 11 of the blower 10, and the wind generated from the fan 11 is rectified so as to suppress the unevenness of the wind speed in the horizontal plane, so that the level in the frame unit 30 can be made. The temperature environment in the direction is more even.

In this way, the overall temperature environment in the frame unit 30 is averaged, whereby the temperature difference between the eggs placed in the frame unit 30 can be suppressed more than ever. Therefore, according to the present embodiment, it is possible to integrate the hatching period of all kinds of eggs and greatly improve workability.

The present invention has been described in detail above, but the embodiment of the present invention is not limited to the embodiment described above, and various modifications may be made without departing from the spirit and scope of the invention. For example, in the above embodiment, a single incubator has been described, and the present invention is also applicable to a double incubator.

Further, the shape, size, number, and the like of the members constituting the hatcher 1 may be appropriately changed, for example, the number of the blower 10 or the frame unit 20, the number of the trays 33 placed in the frame unit 30, and the like. Can be changed appropriately.

It will be obvious to those skilled in the art that various changes in the above-described preferred embodiments are obvious, and the present invention is not limited to the specific embodiments described above. These embodiments are merely illustrative of the present invention and should not be It is to be understood that the scope of the invention is limited and various modifications and changes can be made within the scope of the invention as defined by the appended claims.
