[0002] At present, domestic hatcheries mainly use handheld egg candling devices to candl eggs in hatching trays to identify embryonic development. The handheld egg candling device is equipped with a halogen lamp. In a relatively dim space, the halogen lamp is directed at the large head of the egg at zero distance. The quality and speed of embryonic development of the egg are judged according to the developmental characteristics of the different stages of embryonic development of the egg and experience, and then the problematic quail eggs are manually removed. However, this inspection and screening method can only take quail eggs one by one, and then put them on the egg rack one by one after the inspection, which will inevitably lead to slow detection. For this reason, our company has developed a breeding egg screening device that can screen breeding eggs in batches to achieve rapid detection and screening. Summary of the invention

[0016] In order to make the purpose, technical solution and advantages of this application clearer, the technical solution in the embodiment will be clearly and completely described below in conjunction with the drawings in the embodiment. Obviously, the described embodiment is only a part of the embodiment of this application, not all embodiments. Based on the given embodiments, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0017] In the description of the present application, it should be understood that the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0018] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0019] See Figure 1-5 As shown, the present application discloses a breeding egg screening device that is beneficial to breeding of improved varieties, including a frame 10, a plurality of rotating rollers 20 arranged side by side, and a driving assembly 30, wherein the driving assembly 30 drives the rotating rollers 20 to rotate; the gap between two adjacent rotating rollers 20 is smaller than the minimum size of the breeding eggs, and a light source 40 is arranged between each two adjacent rotating rollers 20, so that the light of the light source 40 is emitted upward from between the two rotating rollers 20. Specifically, each rotating roller 20 includes a rotating shaft 21 and a roller surface 22, wherein the roller surface 22 is dumbbell-shaped and has a circular arc surface, so that it can better fit the outer contour of the breeding eggs. Since the two ends of the breeding eggs are not easy to be too long or too pointed, such a rotating roller 20 can also screen the breeding eggs that do not meet the appearance requirements according to the fit. The driving assembly 30 includes a driving motor 31, a reduction gear set 32, and a synchronous belt transmission group 33, wherein the synchronous belt transmission group 33 includes a synchronous pulley 331 and a synchronous belt 332 connected to each rotating shaft 21, as shown in FIG. Figure 3 As shown, the synchronous belt 332 passes through each synchronous pulley 331 in turn, and the reduction gear set 32 ​​is connected to the transition wheel 333 through the driving shaft, so that the power of the driving motor 31 is reduced by the reduction gear set 32 ​​and drives the transition wheel 333 to rotate, thereby dragging the synchronous belt 332 to drive each synchronous pulley 331 to rotate, and then drive each rotating roller 20 to rotate. Of course, it should be noted that according to Figure 3In the synchronous belt winding mode shown, the rotation directions of the two adjacent rotating rollers 20 are opposite, which is conducive to driving the breeding eggs to roll on the two rotating rollers 20, thereby facilitating the staff to more comprehensively inspect the entire breeding eggs.

[0020] Of course, considering that there may be gaps in the eggs placed on the rotating roller 20 due to mistakes or the lack of eggs, if the light source at the gap continues to shine, it will irritate the eyes of the staff and cause glare, which is not conducive to the staff's inspection of the eggs. For this reason, the present embodiment also includes a breeding egg sensing sensor 50, and a breeding egg sensing sensor 50 is provided between each two adjacent rotating rollers 20; the light source 40 will be lit only when and only when there are breeding eggs placed on the two adjacent rotating rollers 20. In addition, in order to avoid the possible interference of the heat and light of the light source 40 on the breeding egg sensing sensor 50, the present embodiment preferably has the upper end surface of the breeding egg sensing sensor 50 higher than the highest end surface of the light source 40. In addition, the preferred egg sensing sensor 50 is an infrared sensor component, which includes an infrared transmitting tube VD1 and an infrared receiving tube VD2; it also includes an egg detection component circuit, which includes an integrated chip U1, whose pin 1 is connected to one pin of the resistor R3, the other pin of the resistor R3 is connected to the base of the transistor VT1 and the base of the transistor VT2, the 2nd pin is connected to the moving contact of the potentiometer RP1, a fixed point of the potentiometer RP1 is connected to the positive electrode of the power supply VCC and the 8th pin of the integrated chip U1, the other fixed point is connected to the negative electrode of the power supply, and the 3rd pin is connected to the negative electrode of the infrared receiving tube VD2 and one pin of the resistor R2. The positive pole of the infrared receiving tube VD2 is connected to the negative pole of the power supply, the capacitor C2 is connected in parallel with the infrared receiving tube VD2, the other foot of the resistor R2 is connected to the positive pole of the power supply VCC, the infrared transmitting tube VD1 is connected in series with the resistor R1 and then connected between the positive pole of the power supply VCC and the negative pole of the power supply, and the infrared transmitting tube VD1 is connected in parallel with the capacitor C1; the 4th foot of the integrated chip U1 is connected to the negative pole of the power supply; the collector of the transistor VT1 is connected to the negative pole of the power supply, and the light bulb ZM is connected in series between the emitter and the positive pole of the power supply VCC; the collector of the transistor VT2 is connected to the negative pole of the power supply, and the resistor R4 is connected in series between the emitter and the positive pole of the power supply VCC. Specifically, the infrared sensing circuit is composed of the infrared transmitting tube VD1, the infrared receiving tube VD2, and the ceramic capacitors C1 and C2. The voltage sampling and comparison circuit is composed of the potentiometer RP1 and the integrated chip U1 (LM358). When the 5-12V power supply is turned on, the infrared transmitting tube VD1 is turned on, and the infrared light emitted is invisible to the eyes. If the eggs are not placed on the corresponding rotating roller 20 at this time, the infrared receiving tube VD2 does not receive the infrared light, and the infrared receiving tube VD2 is still in the reverse cut-off state. The voltage of the cathode of the infrared receiving tube VD2 is still high and is sent to the 3rd pin of LM358.The voltage of the 2nd foot of LM358 depends on the potentiometer RP1. As long as the potentiometer RP1 is adjusted to the appropriate position, the voltage of the 2nd foot of LM358 is about 2.5V, which can ensure that the voltage of the 3rd foot of LM358 is greater than the voltage of the 2nd foot of LM358. According to the working principle of the comparator, when V+>V-, the 1st foot of LM358 will output a high level and send it to the base of the PNP transistors VT1 and VT2 through the current limiting resistor R3, causing the transistors VT1 and VT2 to be cut off, and the bulb ZM (i.e., the light source 40) will not light up. After the eggs are placed, the infrared light emitted by the infrared transmitting tube VD1 is reflected by the eggs to the infrared receiving tube VD2. The infrared receiving tube VD2 receives the infrared light and is immediately turned on, causing the voltage of the negative electrode of the infrared receiving tube VD2 to drop rapidly, and the voltage is sent to the 3rd foot of LM358. At this time, the voltage at pin 3 of LM358 drops to a value lower than the voltage at pin 2. According to the working principle of the comparator, after the breeding eggs are placed, the bulb ZM (i.e., light source 40) is lit. When the breeding eggs are missing, the bulb ZM (i.e., light source 40) is extinguished or not lit. This solves the problem that when there are no breeding eggs placed between the rotating rollers at the corresponding positions, the lighting source will not be lit, thus avoiding direct light exposure to the eyes of the staff, causing eye discomfort, and making it difficult to continue to check other breeding eggs.

[0021] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
