Description

Technical Field

[0001] The invention relates to the field of salted egg production, and in particular to a method for feeding poultry eggs with mud. Background Art

[0002] As a specialty dish, salted duck eggs have a large demand in the market. At present, the production of salted duck eggs is mostly to put raw duck eggs into a mud pool and wrap them in mud before pickling. Among them, in the mud feeding device, the raw duck eggs are moved to one end of the conveying mechanism under the drive of the conveying mechanism, and then rolled from one end of the conveying mechanism to the inclined guide frame or guide plate and rolled down by their own gravity, and flew out from the lower end of the inclined guide frame or guide plate and fell on the liquid surface of the mud pool. This method is similar to the method of duck eggs falling into the coating box in the patent named "A Grass Ash Salted Duck Egg Processing Device and Processing Technology" and the publication number CN116058405 A. A stirring mechanism for stirring the mud to make it rotate is provided in the mud pool, and the raw duck eggs are moved with the mud by stirring the mud. The raw duck eggs have a small overall density and float on the surface of the mud. Generally, a drooping brush is set above the mud pool to press down the raw duck eggs passing by, so that the raw duck eggs are immersed in the mud as a whole. After being pressed down by the cloth, the raw duck eggs float to the unloading area with the mud, and then the staff will pick up the raw duck eggs. At this time, the surface of the raw duck eggs can be evenly coated with mud.

[0003] However, in the above process, when the raw duck egg rolls down from the guide rack or guide plate, there is a lack of buffering for the raw duck egg. When the raw duck egg falls on the mud surface, its speed is fast and the impact force is large, so there is a probability that the raw duck egg shell will crack. Since the raw duck egg has fallen into the mud pool and is covered with mud, personnel cannot observe whether there are cracks on the raw duck egg shell through the mud layer. Cracks will cause the substances in the raw duck egg to contact external bacteria, causing deterioration and odor. However, the odor is blocked by the hardened mud layer outside the salted duck egg and may not be dissipated. It can only be found when the salted duck egg is cut by the inspector or consumer, resulting in a low qualified rate of salted duck egg products. Summary of the invention

[0004] The invention aims to provide a method for feeding poultry eggs coated with mud, which can slow down the speed of raw eggs falling on the mud pool surface, reduce the impact force on the raw egg shells, avoid the cracking of the raw egg shells as much as possible, and improve the qualified rate of products.

[0005] To achieve the above-mentioned purpose, the present invention provides a method for feeding poultry eggs wrapped in mud. After the egg conveying mechanism conveys the raw eggs to the top of the mud pool, the egg buffering structure receives the raw eggs that have just fallen from the egg output end of the egg conveying mechanism through self-rotation and buffers them, allowing the raw eggs to slowly fall to the liquid surface of the mud pool.

[0006] As a further improvement of the present invention, the egg buffer structure includes an egg receiving portion and a first horizontally arranged rotating shaft; the inner end of the egg receiving portion is connected to the side wall of the first rotating shaft, and the outer end of the egg receiving portion extends outward; when the outer end of the egg receiving portion rotates to be adjacent to the egg output end of the egg conveying mechanism, the front side of the egg receiving portion catches the egg that has just fallen from the egg output end of the egg conveying mechanism, and the egg continues to move slowly downward with the rotation of the egg receiving portion until the outer end of the egg receiving portion is immersed below the liquid surface of the mud pool, and at this time the egg falls on the liquid surface of the mud pool.

[0007] As a further improvement of the present invention, the front side of the egg receiving portion is in an arc-shaped concave shape.

[0008] As a further improvement of the present invention, the egg receiving part is made of elastic material and is fixedly connected to the first rotating shaft; when the egg passes through the outer end of the egg receiving part and falls on the front side of the egg receiving part, the egg receiving part made of elastic material reduces shock to the egg.

[0009] As a further improvement of the present invention, the inner end of the egg receiving part is rotatably connected to the side wall of the first rotating shaft through the second rotating shaft and a torsion spring is provided between the two; a limiting part is also provided on the side wall of the first rotating shaft, and the limiting part is adapted to the back side of the egg receiving part; when the egg passes through the outer end of the egg receiving part and falls on the front side of the egg receiving part, the egg receiving part reduces the shock of the egg by rotating a certain angle relative to the first rotating shaft and twisting the torsion spring, and the limiting part limits the maximum rotation angle of the egg receiving part relative to the first rotating shaft.

[0010] Beneficial Effects

[0011] Compared with the prior art, the advantages of the poultry egg-wrapped mud feeding method of the present invention are:

[0012] 1. When the raw egg just falls from the raw egg output end, the raw egg buffer structure catches the raw egg and moves slowly downward until the raw egg falls on the surface of the mud pool. During this process, the raw egg moves slowly, reducing the impact force on the raw egg shell and avoiding the cracking of the raw egg shell as much as possible. The raw egg will not stink due to cracking, thereby improving the qualified rate of the product.

[0013] 2. The egg buffer structure receives and buffers the eggs through the egg receiving part rotating with the first rotating shaft, and the structure is simple. The limiting end plates at both ends of the egg buffer structure can prevent the eggs falling on the egg receiving part from rolling down to the mud pool surface from the left and right ends of the egg receiving part in advance, thereby preventing the eggs from breaking.

[0014] 3. The front of the egg receiving part is in an arc-shaped concave shape, which can hold the raw eggs. When the egg receiving part rotates downward, it prevents the raw eggs from rolling off the outer end of the egg receiving part in advance, thereby reducing the risk of the raw eggs breaking.

[0015] 4. The egg-laying receiving part is made of elastic material, which plays a buffering role for the eggs when they roll from the egg output end of the egg-laying conveying mechanism to the front of the egg-laying receiving part, further reducing the risk of eggshell cracking.

[0016] 5. The egg-laying receiving part is made of elastic material, which plays a buffering role for the eggs when they roll from the egg output end of the egg-laying conveying mechanism to the front of the egg-laying receiving part, further reducing the risk of eggshell cracking.

[0026] Now, the embodiments of the present invention will be described with reference to the accompanying drawings.

[0027] Embodiment 1

[0028] The specific implementation of the present invention is as Figures 1 to 6As shown in the figure, a poultry egg mud coating feeding device includes an adjacent raw egg conveying mechanism 1 and a mud pool 4. The raw egg output end of the raw egg conveying mechanism 1 is located above the liquid level of the mud pool 4. A raw egg buffer structure 2 is provided between the raw egg output end of the raw egg conveying mechanism 1 and the liquid level of the mud pool 4. The raw egg buffer structure 2 can catch the raw egg 10 that has just fallen from the raw egg output end by self-rotation and make the raw egg 10 slowly fall on the liquid level of the mud pool 4.

[0029] The raw egg buffer structure 2 includes a raw egg receiving part 23 and a horizontally arranged first rotating shaft 22. The inner end of the raw egg receiving part 23 is connected to the side wall of the first rotating shaft 22, and the outer end of the raw egg receiving part 23 extends outward and can be rotated to be adjacent to the raw egg output end of the raw egg conveying mechanism 1. The side of the raw egg receiving part 23 for receiving the raw egg 10 is the front. Both ends of the first rotating shaft 22 are rotatably installed on the bracket through bearings and bearing seats. The bracket is relatively fixed to the mud pool 4, and the two can be fixedly connected to each other. The bracket can also be directly installed on the ground.

[0030] The raw egg buffer structure 2 further includes limit end plates 21. The number of limit end plates 21 is two, and they are respectively connected to the left and right ends of the first rotating shaft 22. The raw egg receiving part 23 is located between the two limit end plates 21. The outer edges of the left and right limit end plates 21 are located outside the raw egg output end of the raw egg conveying mechanism 1, as Figure 4 shown.

[0031] The front of the raw egg receiving part 23 is in an arc concave shape. In this embodiment, the raw egg receiving part 23 is made of an elastic material and is fixedly connected to the first rotating shaft 22.

[0032] The number of the raw egg receiving parts 23 is at least two and they are arranged around the first rotating shaft 22. One end of the first rotating shaft 22 is linked with a first driving device 3. In this embodiment, 6 raw egg receiving parts 23 are connected to the first rotating shaft 22, and the raw egg receiving parts 23 are in a plate shape. In addition, the raw egg receiving parts 23 can also adopt a mesh structure.

[0033] Among them, the first driving device 3 includes a first motor 31 and a transmission mechanism 32 that are linked in sequence. The first motor 31 is installed on the bracket, and the transmission mechanism 32 can adopt a gear set transmission structure or a belt pulley transmission structure. The output end of the transmission mechanism 32 is linked with the first rotating shaft 22. When the first motor 31 starts, it drives the whole first motor 31 to rotate around its own axis.

[0034] The raw egg conveying mechanism 1 includes a plurality of conveying rollers 11, and the conveying rollers 11 are parallel to each other and arranged in sequence along the conveying direction. In this embodiment, the arrangement direction of the conveying rollers 11 is inclined upward, that is, the raw eggs 10 located on the conveying rollers 11 are conveyed obliquely upward through the active rotation of the conveying rollers 11, and the raw egg output end of the raw egg conveying mechanism 1 is located at its highest point. The axes of the conveying rollers 11 and the raw egg buffer structure 2 are horizontally arranged, and the rotation directions of the conveying roller 11 and the raw egg buffer structure 2 are opposite to each other. Each conveying roller 11 is linked with a second motor 12 through a transmission structure. The second motor 12 is installed on the bracket, and both ends of each conveying roller 11 are also rotatably connected to the bracket. At least two concave surfaces 111 adapted to the raw eggs 10 are provided on each conveying roller 11, and the concave surfaces 111 are arranged in sequence along the length direction of the conveying roller 11. An arc-shaped flange 231 is provided at the outer end of the raw egg receiving portion 23, and the arc-shaped flange 231 of the raw egg receiving portion 23 is adapted to the concave surface 111 of the conveying roller 11 at the raw egg output end of the raw egg conveying mechanism 1. That is, when the arc-shaped flange 231 of the raw egg receiving portion 23 rotates to be adjacent to the concave surface 111 of the conveying roller 11, a small gap is left between the two. The width dimension of this gap is much smaller than the maximum diameter and length of the raw egg 10 to prevent the raw egg 10 from being stuck in this gap. In Figure 2 , Figure 6 , each conveying roller 11 rotates counterclockwise, the raw egg buffer structure 2 rotates clockwise, and the first rotating shaft 22 of the raw egg buffer structure 2 is located on the left side of the raw egg output end of the raw egg conveying mechanism 1.

[0035] In Figure 1 , both the raw egg buffer structure 2 and the raw egg conveying mechanism 1 are located on the right side of the mud pool 4. Among them, when the outer end of the raw egg receiving portion 23 of the raw egg buffer structure 2 rotates to the lowest point, the outer end of the raw egg receiving portion 23 is located below the liquid level of the mud 5 in the mud pool 4, as shown in Figure 2 and Figure 6 .

[0036] A stirring device 6 is provided in the mud pool 4. The stirring device 6 includes a third motor 61, a third rotating shaft 62, and a stirring rod 63 that are connected in sequence. The third motor 61 is fixedly connected to the bottom surface of the mud pool 4. The third motor 61 is linked with the lower end of the vertically arranged third rotating shaft 62. The stirring rod 63 is horizontally arranged and one end thereof is connected to the side wall of the third rotating shaft 62. The third rotating shaft 62 and the stirring rod 63 are both located in the mud pool 4. When the third motor 61 is started, it drives the stirring rod 63 to rotate to stir the mud 5. Figure 1 In

[0037] , as shown in Figure 1 , a cross beam 9 is provided above the middle of the mud pool 4. Both ends of the cross beam 9 are fixedly connected to the side walls of the mud pool 4 through connecting rods 91, as shown in Figure 3 . As shown in Figure 3As shown in the figure, a flexible brush 7 is connected below one section of the cross beam 9, and the lower end of the flexible brush 7 hangs down to the liquid surface of the slurry 5; multiple vertical rods 8 are connected below the other section of the cross beam 9, and the vertical rods 8 are arranged along the length direction of the cross beam 9. The distance between adjacent vertical rods 8 is less than the maximum diameter and length dimensions of the raw eggs 10, and is used for the raw eggs 10 to pass through.

[0038] The method for feeding poultry eggs with slurry is as follows:

[0039] The raw egg buffer structure 2 rotates to catch and buffer the raw egg 10 that has just fallen from the raw egg output end of the raw egg conveying mechanism 1. The specific process is that the raw egg conveying mechanism 1 first conveys the raw egg 10 above the slurry pool 4. When the raw egg 10 just moves to the raw egg output end of the raw egg conveying mechanism 1, at this time, the outer end of the raw egg receiving part 23 just rotates to one side of the raw egg output end of the raw egg conveying mechanism 1. The raw egg 10 rolls and passes through the outer end of the raw egg receiving part 23 and lands on the front of the raw egg receiving part 23. The raw egg receiving part 23 made of elastic material cushions the raw egg 10. The raw egg 10 continues to move down slowly with the rotation of the raw egg receiving part 23 until the outer end of the raw egg receiving part 23 sinks below the liquid surface of the slurry pool 4, and the raw egg 10 slowly lands on the liquid surface of the slurry 5 in the slurry pool 4. Figure 1 In the figure, the raw egg 10 that falls on the right side in the slurry pool 4 rotates clockwise with the slurry 5. First, it passes through the flexible brush 7. The flexible brush 7 presses the raw egg 10 floating on the liquid surface of the slurry 5 downward by its own gravity, so that the whole raw egg 10 is immersed in the slurry 5. After passing through the lower part of the flexible brush 7, the raw egg 10 moves to the left side in the slurry pool 4, and the operator picks up the raw egg 10 wrapped with slurry from this side. Even if the raw egg 10 that has not been picked up in time continues to move clockwise with the slurry 5, it will be blocked by the vertical rod 8 and will not float back to the feeding end on the right side of the slurry pool 4.

[0040] Embodiment 2

[0041] As Figure 7 shown, the difference from Embodiment 1 is that the inner end of the raw egg receiving part 23 is rotatably connected to the side wall of the first rotating shaft 22 through a second rotating shaft 24, and a torsion spring (not shown in the figure, the setting method is similar to the torsion spring in a clip) is provided between the two. The torsion spring is sleeved on the second rotating shaft 24. In Figure 7 the figure, the torsion spring provides a counterclockwise supporting force for the raw egg receiving part 23 (the raw egg buffer structure 2 rotates clockwise). A limiting part 25 is also provided on the side wall of the first rotating shaft 22, and the limiting part 25 is adapted to the back surface of the raw egg receiving part 23.

[0042] When the raw egg 10 falls onto the front surface of the raw egg receiving part 23 through the outer end of the raw egg receiving part 23, the raw egg receiving part 23 rotates a certain angle relative to the first rotating shaft 22 and twists the torsion spring to shock-absorb the raw egg 10, and the limiting part 25 limits the maximum rotation angle of the raw egg receiving part 23 relative to the first rotating shaft 22 to prevent the raw egg 10 from falling from the outer end of the raw egg receiving part 23 in advance due to excessive swinging angle.

[0043] The present invention has been described in conjunction with the best embodiments, but the present invention is not limited to the disclosed embodiments above, and should cover various modifications and equivalent combinations made according to the essence of the present invention.
