[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: an egg sieving device, including a workbench 1, with support legs installed at the bottom of the workbench 1, and a weighing seat 2 and a control box 8 provided on the top of the workbench 1. The weighing seat 2 is used to weigh eggs, and the control box 8 provides control programs and operating components for the weighing and sieving of this device.

[0022] In this technical solution, the top of the weighing seat 2 is provided with a spherical protrusion 3 and at least three rails 4 evenly distributed around the spherical protrusion 3. The spherical protrusion 3 serves to support the egg and facilitate the egg's rolling. The rails 4 serve to limit the egg on the spherical protrusion 3. After the egg is placed, the weighing seat 2 weighs the egg.

[0023] Furthermore, the tops of at least three barriers 4 are rotatably connected to the top of the weighing base 2, and their rotation axes intersect to form an equilateral polygon. Preferably, the outer spherical wall of the spherical protrusion 3 is fixedly connected to a portal frame 31 near its outer edge. The barriers 4 are U-shaped rods with their free ends rotatably connected to the top of the portal frame 31. The bottom of the barriers 4 acts as a blocking and limiting mechanism for the eggs. That is, when the bottom of one barrier 4 swings outward, a gap is formed at the position of that barrier 4, and the eggs on the spherical protrusion 3 will roll off the gap towards the outward-swinging barrier 4. In use, one barrier 4 corresponds to an egg of a certain weight range. Therefore, when one barrier 4 is opened, the corresponding weight of the egg rolls away from the weighing base 2 in the corresponding direction, thus achieving egg sieving. In use, the barrier 4 is covered with a protective silicone sleeve 41, which effectively protects the eggs and prevents damage from collisions.

[0024] The workbench 1 is equipped with inclined drainage channels 7, each corresponding to a barrier 4. The higher end of each inclined drainage channel 7 extends to a spherical protrusion 3 and is located below the barrier 4. The function of the inclined drainage channels 7 is to guide the eggs using their inclination. The cross-section of the inclined drainage channels 7 is U-shaped. During use, a buffer sponge pad 71 is adhered to the inner side of the inclined drainage channel 7 at the end away from the spherical protrusion 3. The buffer sponge pad 71 reduces the speed at which the eggs detach from the inclined drainage channels 7. Preferably, the weighing base 2 is a disc structure with its bottom fixedly connected to the workbench 1. The support column 32 and the weighing seat 2 have positioning notches 21 on their outer periphery that are opposite to the guardrail 4. One end of the inclined drainage channel 7 is fixedly connected to the positioning notch 21. Thus, the eggs that have rolled away will enter the inclined drainage channel 7. The inclined drainage channel 7 uses its inclination in combination with the weight of the eggs to make the eggs roll down. In other words, the inclined drainage channel 7 plays the role of transporting eggs. When in use, a turnover tray can be placed on the workbench 1 below the outlet end of each inclined drainage channel 7 so that the bottom of the inclined drainage channel 7 and the top of the turnover tray are approximately in contact with each other to avoid the impact of the eggs falling.

[0025] Among them, a control assembly 5 for controlling the rotation of the guardrail 4 is provided at the bottom of the weighing base 2. The control assembly 5 here has the function of controlling the rotation of each guardrail 4 separately.

[0026] Specifically, the horizontal shaft 311 at the top of the portal frame 31 is rotatable, and the free end of the barrier 4 is fixedly connected to the outer peripheral wall of the horizontal shaft 311. Thus, when the horizontal shaft 311 is rotated, it can drive the barrier 4 to swing. The control assembly 5 includes an electric push rod 51, a gear 52, and a rack 53. One portal frame 31 corresponds to one control assembly 5. One end of the horizontal shaft 311 is fixedly fitted with a gear 52. The electric push rod 51 is fixedly mounted on the weighing base 2, and its output shaft is connected to the rack 53 through an elastic telescopic rod 511. The rack 53 meshes with the gear 52, and when the rack 53 moves up and down, it drives the barrier 4 to swing. The rotation of gear 52 drives the horizontal shaft 311 to rotate. The electric push rod 51 provides driving force for the up-and-down movement of rack 53. The elastic telescopic rod 511 adopts a common two-section telescopic structure with built-in springs. Its function is to give the barrier 4 a buffer swing characteristic. In use, in the initial state, the bottom of the barrier 4 is in an inward tilted state. When placing an egg on the spherical protrusion 3, the egg will first contact the lower part of the barrier 4. After the barrier 4 receives pressure, it will swing down. The elastic telescopic rod 511 will compress and buffer. Then the bottom of the egg will contact the top of the spherical protrusion 3, thereby improving the safety of placing the egg when weighing it.

[0027] In this embodiment, the control box 8 includes a box body 81, a control panel 82, and a control circuit board. The box body 81 is fixedly mounted on the workbench 1 near the side by support legs. The control panel 82 is fixedly mounted on the front side of the box body 81. The control panel 82 is equipped with operation buttons and a display screen. The control circuit board is equipped with a programmable single-chip microcomputer. The control circuit board is located inside the box body 81. A weight sensor 9 is provided on the top of the spherical protrusion 3. In a specific implementation, a recess for nesting the weight sensor 9 can be made on the top of the spherical protrusion 3. The weight sensor 9 and the electric push rod 51 are both electrically connected to the control circuit board. After weighing, the control circuit board controls the corresponding electric push rod 51 to move according to the program settings.

[0028] In use, a single egg is placed manually on the spherical protrusion 3. When the barrier 4 is pushed open, the weight sensor 9 at the top of the spherical protrusion 3 is pressed by the egg, which controls the movement of all the electric push rods 51 to make all the barriers 4 swing outward at a certain angle and delay. At this time, the barriers 4 will not affect the accuracy of the egg weighing. After the weight sensor 9 detects the weight, it controls the corresponding barrier 4 to open and then controls the other barriers 4 to reset. At this time, the egg will roll into the corresponding inclined drainage channel 7 and then into the corresponding turnover tray.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
