Description

Technical Field

[0001] This utility model relates to the technical field of egg sorting equipment, specifically a grading, screening, and automatic arrangement device for sea duck eggs. Background Technology

[0002] Sea duck eggs, as a highly nutritious food, have seen increasing market demand in recent years. Grading and sorting are crucial steps in processing sea duck eggs into salted duck eggs. Eggs of suitable size and similar dimensions must be selected for salting, as inconsistencies in size can lead to differences in taste. Unqualified eggs must be sold in the market. Traditionally, sea duck egg sorting and grading rely heavily on manual labor, which is inefficient and prone to shell damage, affecting product quality. Furthermore, manual sorting struggles to guarantee accurate grading, resulting in inconsistent product specifications and impacting market competitiveness.

[0003] While existing automated sorting equipment has improved efficiency to some extent, it still has some problems. For example, its design is flawed, causing duck eggs to easily get stuck or break during the sorting process; substandard duck eggs need to be arranged onto egg trays using a sorting mechanism for subsequent transportation and sale, but the existing sorting mechanism is inefficient and prone to causing collisions that damage the duck eggs.

[0004] Therefore, there is a need for a device that can efficiently and accurately grade, screen, and automatically arrange sea duck eggs to improve production efficiency and product quality. Utility Model Content

The mounting frame has supporting legs at its bottom. The screening screen includes a first sieve section and a second sieve section, with the mesh size of the first sieve section being smaller than that of the second sieve section. A sorting mechanism is positioned below the first sieve section to arrange the sea duck eggs sorted by the first sieve section into an egg tray. A transport and egg-dispensing device is positioned below the second sieve section to dispense the sea duck eggs sorted by the second sieve section into a tumbling mud tank for the next process.

[0008] Preferably, the screening net is composed of numerous horizontal and vertical bars intersecting at 90 degrees, and the mesh of the screening net is elongated, which facilitates the rolling of the sea duck eggs.

[0009] Preferably, the egg transport device includes a transport frame spanning the bottom of the mounting frame and a first chain support conveyor belt circulating within the transport frame. The first chain support conveyor belt circulates and transports the screened sea duck eggs into the tumbling mud tank of the next process.

[0010] Preferably, the arrangement mechanism includes a mounting frame disposed below the first sieve, a second chain support conveyor belt disposed in the mounting frame, and a plurality of dividing strips disposed above the second chain support conveyor belt. The tail end of the dividing strip is provided with a vertical arranging plate for placing sea duck eggs. The vertical arranging plate is connected to the drive assembly. The inner bottom of the vertical arranging plate is provided with a carrier plate for supporting the sliding of sea duck eggs. The tail end face of the mounting frame is provided with a placement rack for placing egg trays.

[0011] Preferably, the driving component is a linear motor, the main rod of the linear motor is connected to the vertical plate, and the top surface of the placement rack is provided with a positioning block for limiting the position of the egg tray.

[0012] Preferably, a feeding device is provided at one end of the mounting frame near the first screen, the feeding device being used to extract bulk sea duck egg raw materials and feed them onto the screening screen.

[0015] This utility model discloses a grading and automatic sorting device for sea duck eggs. By using screening screens with different mesh sizes, it can efficiently and accurately grade sea duck eggs according to size. The first screening section selects smaller sea duck eggs, which are then automatically sorted and arranged into egg trays by a sorting mechanism, ensuring neat arrangement and minimizing breakage for subsequent market sales. The second screening section selects larger sea duck eggs, which are then transported to a mud-tumbling tank in the next process step via a transport and feeding device, ensuring that the selected sea duck eggs are of approximately the same size. This device has a simple structure, is easy to operate, and can significantly improve the efficiency of grading, sorting, and arranging sea duck eggs, reduce manual intervention, lower breakage rates, and improve product quality.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 6 As shown, this utility model is a grading, screening, and automatic arrangement device for sea duck eggs. The device includes a conveying device for propelling the sea duck eggs, comprising a mounting frame 1, a rotating lever chain 2 disposed within the mounting frame 1, and a screening screen 3 positioned below the lever chain 2. A support frame 4 is provided at the bottom of the mounting frame 1. The screening screen 3 includes a first sieve section 5 and a second sieve section 6, with the mesh size of the first sieve section 5 being smaller than that of the second sieve section 6. An arrangement mechanism 7 is provided below the first sieve section 5, used to arrange the sea duck eggs screened by the first sieve section 5 into egg trays. A transport and egg-dispensing device 8 is provided below the second sieve section 6, used to dispense the sea duck eggs screened by the second sieve section 6 into a tumbling mud tank for the next process.

[0025] Furthermore, in this embodiment, the screening net 3 is composed of numerous horizontal and vertical bars intersecting at 90-degree angles. The mesh of the screening net 3 is elongated, which facilitates the rolling of the duck eggs. The egg transport and delivery device 8 includes a transport frame 9 spanning across the bottom of the mounting frame 1 and a first chain support conveyor belt 10 circulating within the transport frame 9. The first chain support conveyor belt 10 circulates and transports the screened duck eggs into the tumbling mud tank for the next process.

[0026] Specifically, the arrangement mechanism 7 includes a mounting frame 11 located below the first sieve section 5, a second chain support conveyor belt 12 located within the mounting frame 11, and several dividing strips 13 located above the second chain support conveyor belt 12. The dividing strips 13 separate the eggs that fall from the first sieve section 5. Preferably, the number of compartments formed by the dividing strips 13 is the same as the number of egg placement positions in a row of egg trays. Furthermore, the tail end of the dividing strips 13 is provided with a vertical arranging plate 14 for placing duck eggs. The vertical arranging plate 14 is connected to the drive assembly 15, and the inner bottom of the vertical arranging plate 14 is provided with a carrier plate 16 to support the sliding of the duck eggs. The tail end face of the mounting frame 11 is provided with a placement rack 17 for placing egg trays.

[0027] Specifically, the drive assembly 15 uses a linear motor, the main rod of which is connected to the vertical plate 14. The linear movement of the linear motor pulls the vertical plate 14 to extend and retract, thereby allowing the egg drop opening of the vertical plate 14 to be controlled and adjusted to different positions on the egg tray for egg dropping. Furthermore, the top surface of the placement rack 17 is provided with a positioning block 18 for limiting the position of the egg tray to ensure the correct placement position each time. In addition, a feeding device 19 is provided at the end of the mounting frame 1 near the first sieve section 5. The feeding device 19 is used to extract and feed the bulk sea duck egg raw materials onto the screening screen 3. A residual material storage device 20 is provided at the end of the mounting frame 1 near the second sieve section 6. The residual material storage device 20 is used to receive sea duck eggs that have passed through the screening screen 3 but have not been screened out, greatly saving labor costs.

[0028] like Figure 1 and Figure 3 As shown, a support bracket 4 is provided at the bottom of the mounting frame 1, which is used to stably support the entire device. The lever chain 2 rotates cyclically within the mounting frame 1, pushing the duck eggs to roll on the screening mesh 3. Figure 5 As shown, the first sieve section 5 and the second sieve section 6 of the screening net 3 respectively screen out sea duck eggs of different sizes. The smaller sea duck eggs screened out by the first sieve section 5 are neatly arranged into the egg tray by the arranging mechanism 7, while the larger sea duck eggs screened out by the second sieve section 6 are put into the mud rolling pool of the next process by the egg transport and throwing device 8.

[0029] like Figures 1 to 6As shown, when using this duck egg grading and automatic sorting device, the worker first feeds the bulk duck egg raw materials onto the screening screen 3 via the feeding device 19. The rotating lever chain 2 pushes the duck eggs to roll on the screening screen 3. The first sieve 5 filters out smaller duck eggs, and the sorting mechanism 7 places them into egg trays. Once the trays are full, they are manually replaced. The second sieve 6 filters out larger duck eggs, and the transport and egg-discharging device 8 places them into the tumbling mud pool for the next process. The waste material storage device 20 receives duck eggs that have passed through the screening screen 3 but have not been screened out, ensuring smooth operation of the device.

[0030] After sorting, workers remove the egg trays from the placement rack 17 and clean the duck eggs from the residual material storage device 20 to ensure the device is clean. The device has a simple structure and is easy to operate, which can significantly improve the efficiency of grading, sorting and arranging duck eggs, reduce manual intervention, reduce breakage rate and improve product quality.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
