Description

Technical Field

[0001] The utility model relates to the technical field of poultry egg processing, in particular to a poultry egg shelling line. Background Technique

[0002] A runny egg is a hard-boiled egg with a runny yolk. A popular way to eat it is to soak the cooked runny egg in soy sauce for 2 days. Some people also eat it directly with pasta after cooking. When making a runny egg, the temperature needs to be accurately controlled so that the eggs are submerged in water, and then the egg whites are steamed at an appropriate temperature to solidify the egg whites while keeping the yolks in a liquid state.

[0003] During the processing of runny eggs, after the eggs are cooked, they need to be shelled. The traditional shelling method is to manually remove the eggshells, which has a high labor intensity, low efficiency, and is prone to scalding. To solve the problems existing in traditional manual shelling, an egg shelling machine has emerged in the prior art. Its principle is that the rotation of the motor drives the gears to operate, driving the shelling mechanism to move, generating friction with the egg surface to tear the eggshell from the surface, and the eggshell is pulled away by the roller shaft to complete the shelling process.

[0004] The existing method is to uniformly and orderly transport the eggs to the shelling machine for shelling. Therefore, there are the following problems: Since the spacing between the shelling rollers of the shelling machine is fixed and uniform, while the egg sizes are different, some eggs with smaller sizes may not be completely shelled, and some eggs with larger sizes may have their integrity damaged. Summary of the Utility Model

[0005] Therefore, to solve the above deficiencies, the utility model provides a poultry egg shelling line here, including:

[0006] A grading device, the grading device includes a conveying roller group and a grading roller group. The conveying roller group drives the poultry eggs to move. There are multiple groups of the grading roller group, and the multiple groups of the grading roller group are linearly distributed. One group of the grading roller group at the end is connected to the conveying roller group. The discharge gap of the grading roller group gradually increases from the grading roller group at the starting end to the grading roller group at the tail end. The grading roller group at the starting end is the group of grading roller group connected to the conveying roller group, and the grading roller group at the tail end is the grading roller group farthest from the conveying roller group among the multiple groups of the grading roller group. The discharge gap is the gap between adjacent rollers in each group of the grading roller group;

[0007] Shelling device, the shelling device includes a box body and a shelling member. There are shelling cavities in the box body corresponding to the number of the above-mentioned grading roller groups. The shelling member is installed in the shelling cavity. At least one group of shelling members is provided in each shelling cavity. The shelling gap of the shelling member increases successively from the shelling member at the starting end to the shelling member at the tail end. The shelling member at the starting end is the shelling member arranged in the shelling cavity at the starting end, and the shelling member at the tail end is the shelling member arranged in the shelling cavity at the tail end. The shelling cavity at the tail end is the shelling cavity connected to the grading roller group at the starting end, and the shelling cavity at the tail end is the shelling cavity connected to the grading roller group at the tail end;

[0008] The shelling member includes:

[0009] A feeding roller, on which a feeding part is spirally wound around the outer peripheral surface of the feeding roller;

[0010] A smooth rod, one end of which is fixedly connected to the side wall of the shelling cavity. The smooth rod is arranged adjacent to the feeding roller and is arranged on one side below the feeding roller;

[0011] A shelling roller, which is arranged on the side of the smooth rod away from the feeding roller and is arranged on one side above the smooth rod;

[0012] The feeding roller, the smooth rod and the shelling roller are parallel to each other, and the feeding roller, the smooth rod and the shelling roller together form a shelling channel for the movement of eggs;

[0013] One end of the smooth rod not connected to the side wall of the shelling cavity forms a discharge port for the eggs to be discharged with the side wall of the shelling cavity;

[0014] The shelling gap includes the gap between the feeding roller and the smooth rod, the gap between the smooth rod and the shelling roller, and the gap between adjacent shelling rollers.

[0015] In this utility model, the conveying roller group drives the eggs to move towards the grading roller group. After being screened and graded by multiple grading roller groups, the eggs are sent to different shelling cavities according to their specifications respectively. The shelling member with a matching shelling gap is used to shell the eggs, so as to realize the simultaneous shelling of eggs of different specifications, improve the efficiency, and avoid the situation of incomplete shelling or incomplete products.

[0016] Further, the shelling device further includes:

[0017] A slag discharge port, which is arranged corresponding to the lower part of the smooth rod;

[0018] A discharge port, which is arranged corresponding to the lower part of the discharge port;

[0019] Slag discharge conveying, which is arranged corresponding to the lower part of the slag discharge port.

[0020] By setting the slag discharge port and the discharging port, the eggshells and the egg products can be discharged separately, avoiding the mixing of eggshells and egg products, which is difficult to clean. The eggshells are sent to the eggshell collection place through the slag discharge conveyor for centralized treatment of the eggshells.

[0021] Furthermore, the poultry egg shelling line further includes a shell knocking device, and the shell knocking device is connected to the grading device;

[0022] The shell knocking device includes:

[0023] A shell knocking conveyor line that drives the movement of the poultry eggs through the shell knocking conveyor line;

[0024] A power device that drives the movement of the shell knocking conveyor line through the power device;

[0025] A shell knocking part that is arranged above the shell knocking conveyor line and drives the shell knocking part to move vertically and reciprocally through the power device.

[0026] The power device drives the shell knocking conveyor line to move so as to send the poultry eggs below the shell knocking part. At the same time, under the action of the power device, the shell knocking part slides vertically downward to break the eggshells of the poultry eggs. After the eggshells are broken, it is easier and more complete for the shelling device to shell the eggs.

[0027] Furthermore, the shell knocking conveyor line includes a plurality of egg feeding parts, and at least one egg receiving hole matching the shape of the poultry eggs is arranged on the surface of the egg feeding part;

[0028] An egg supporting part is fixed on the egg feeding part, and the egg supporting part straddles the egg receiving hole and remains fixed to the egg feeding part. The egg supporting part is made of a flexible material.

[0029] The poultry eggs are limited by the egg receiving holes to avoid rolling of the poultry eggs on the shell knocking conveyor, and the poultry eggs are supported by the egg supporting part to prevent the poultry eggs from leaking out of the egg receiving holes.

[0030] Furthermore, the shell knocking device further includes a guide trough, and a guide channel corresponding to the above-mentioned egg receiving holes is arranged in the guide trough, and a plurality of poultry eggs distributed linearly in a single row are limitedly accommodated in the guide channel.

[0031] The poultry eggs are temporarily stored through the guide trough and guided into the egg receiving holes, thereby avoiding the chaotic entry of the poultry eggs into the shell knocking conveyor line, resulting in some poultry eggs not being able to be accommodated in the egg receiving holes and rolling.

[0032] Furthermore, the poultry egg shelling line further includes a cooling device, and the cooling device is connected to the shell knocking device;

[0033] The cooling device includes:

[0034] A cooling box that limitedly accommodates a coolant in the cooling box;

[0035] The first lifting conveyor, the lower part of the first lifting conveyor is arranged in the cooling box, and the upper part of the first conveyor is connected to the shell knocking device.

[0036] By first soaking the eggs in the coolant in the cooling process, due to the different degrees of cold shrinkage of the eggshell membrane and the egg white, after soaking in the coolant, a relatively large gap will be formed between the eggshell membrane and the egg white, thus facilitating the peeling of the eggshell.

[0037] Furthermore, there is a sandwich layer in the side wall of the cooling box, and a cooling coil connected to the refrigeration device is arranged in the sandwich layer.

[0038] The refrigerant is input into the cooling coil through the refrigeration device to exchange heat with the coolant in the cooling box, so as to maintain the temperature of the coolant and avoid frequent replacement of the coolant.

[0039] Furthermore, the egg shelling line further includes a rolling device, the rolling device is arranged between the grading device and the shelling device, and the rolling device is arranged corresponding to the grading roller group to receive the eggs discharged from the grading gap;

[0040] The rolling device includes:

[0041] The feeding conveyor, which is connected to the grading device;

[0042] The rolling conveyor, the rolling conveyor is arranged above the feeding conveyor;

[0043] A rolling gap is formed between the rolling conveyor and the feeding conveyor, and the rolling gap increases sequentially from the rolling device at the starting end to the rolling device at the tail end;

[0044] The rolling device at the starting end is the rolling device that receives the eggs discharged from the grading roller group at the starting end, and the rolling device at the tail end is the rolling device that receives the eggs discharged from the grading roller group at the tail end.

[0045] The eggs are squeezed by the rolling conveyor and driven to roll, so as to completely crush the eggshell, which is convenient for peeling the eggshell. By designing multiple rolling devices that match the egg specifications according to the egg specifications, the eggshell can be completely squeezed and broken, avoiding damage to large eggs by extrusion or incomplete crushing of small eggs by rolling.

[0046] Furthermore, the rolling device further includes two groups of adjusting components, the adjusting components include adjusting rods, rotating the adjusting rods to make the adjusting rods move vertically, the adjusting rods are connected to the rolling conveyor through connecting shafts, the connecting shafts rotate circumferentially relative to the rolling conveyor, and the adjusting rods rotate circumferentially relative to the connecting shafts.

[0047] By rotating the adjusting rod, the height and angle of the rolling transportation can be adjusted according to the actual usage situation, improving the flexibility of the device.

[0048] Furthermore, the egg shelling line further includes an antifoaming device, and the antifoaming device is connected to the shelling device;

[0049] The antifoaming device includes:

[0050] An antifoaming box, and the antifoaming box contains a limited amount of disinfectant solution;

[0051] A third lifting conveyor line, the lower part of the third lifting conveyor line is arranged in the antifoaming box, and the upper part extends out of the antifoaming box from the mouth of the antifoaming box.

[0052] After the egg shelling is completed, the eggs move into the antifoaming box, and the shelled eggs are disinfected by the disinfectant solution in the antifoaming box, thereby reducing the harmful bacteria on the surface of the eggs. The disinfected eggs are lifted out of the antifoaming box by the third lifting conveyor line and sent to the next process.

[0053] The utility model has the following advantages:

[0054] In the utility model, the conveying roller group drives the eggs to move towards the grading roller group. After being screened and graded by multiple grading roller groups, the eggs are sent to different shelling cavities according to their specifications, and the shelling member with a matching shelling gap is used to shell the eggs, thereby realizing the simultaneous shelling of eggs of different specifications, improving the efficiency, and avoiding the situations of incomplete shelling or incomplete products.

[0055] By providing a slag discharge port and a discharge port, the eggshells and the egg products can be discharged separately, avoiding the eggshells and the egg products being mixed together and difficult to clean. The eggshells are centrally sent to the eggshell collection place through the slag discharge conveyor for centralized treatment of the eggshells.

[0056] The power device drives the shell knocking conveyor line to move so as to send the eggs to the lower part of the egg knocking part. At the same time, under the action of the power device, the egg knocking part slides vertically downward to break the eggshells of the eggs. After the eggshells are broken, it is easier and more complete for the shelling device to shell the eggs.

[0057] By limiting the eggs through the egg receiving holes, the eggs can be prevented from rolling on the shell knocking conveyor, and the eggs are supported by the egg supporting part to prevent the eggs from leaking out of the egg receiving holes.

[0058] The eggs are temporarily stored through the material guiding groove and guided into the egg receiving holes, thereby preventing the eggs from entering the shell knocking conveyor line in a disorderly manner, resulting in some eggs not being able to be accommodated in the egg receiving holes and rolling.

[0059] By first immersing the poultry eggs in the coolant being cooled, due to the different degrees of contraction of the eggshell membrane and the egg white upon cooling, a relatively large gap will form between the eggshell membrane and the egg white after immersion in the coolant, thus facilitating the peeling of the eggshells of the poultry eggs.

[0060] The refrigerant is input into the cooling coil through the refrigeration device to exchange heat with the coolant in the cooling tank, thereby maintaining the temperature of the coolant and avoiding frequent replacement of the coolant.

[0061] Exert extrusion on the poultry eggs through roller conveying and drive them to roll, thereby completely crushing the eggshells, facilitating the peeling of the eggshells of the poultry eggs. By designing multiple roller devices that match the specifications of the poultry eggs according to the specifications of the poultry eggs, complete extrusion and crushing of the eggshells can be achieved, avoiding damage to oversized poultry eggs by extrusion or incomplete crushing of undersized poultry eggs by rolling.

[0062] By rotating the adjusting rod, the height and angle of the roller conveying can be adjusted according to the actual usage situation, improving the flexibility of the device.

[0063] After the shelling of the poultry eggs is completed, they move into the defoaming tank, and the shelled poultry eggs are disinfected by the disinfectant in the defoaming tank, thereby reducing the harmful bacteria on the surface of the poultry eggs. The disinfected poultry eggs are lifted out of the defoaming tank by the third lifting conveyor and sent to the next process. Description of the Drawings

[0090] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application.

[0091] In this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0092] As described in the background art, the existing method is to uniformly and orderly convey eggs to a shelling machine for shelling treatment. Therefore, the following problems exist: Since the spacing between the shelling rollers of the shelling machine is fixed and uniform, while the egg sizes are different, it will cause incomplete shelling of smaller eggs and damage the integrity of larger eggs.

[0093] Embodiment 1:

[0094] Therefore, in order to solve the above technical problems existing in the prior art, this embodiment provides a poultry egg shelling line as Figures 1 - 3 shown. The poultry egg shelling line includes:

[0095] A grading device 430, as Figure 11As shown, the grading device includes a conveying roller group 431 and a grading roller group 432. The conveying roller group drives the eggs to move. There are multiple groups of the grading roller group, and the multiple groups of the grading roller group are linearly distributed. One group of the grading roller group at the end is connected to the conveying roller group. The discharging gap of the grading roller group increases successively from the grading roller group at the starting end to the grading roller group at the tail end. The grading roller group at the starting end is the group of grading roller group connected to the conveying roller group. The grading roller group at the tail end is the grading roller group farthest from the conveying roller group among the multiple groups of the grading roller group. The discharging gap is the gap between adjacent rollers in each group of the grading roller group;

[0096] The shelling device 470, as Figure 14 shown, the shelling device 470 includes a box body 461 and a shelling member. The box body 461 is provided with shelling cavities corresponding to the number of the above-mentioned grading roller groups. The shelling member is installed in the shelling cavity. At least one group of shelling members is provided in each shelling cavity. The shelling gap of the shelling member increases successively from the shelling member at the starting end to the shelling member at the tail end. The shelling member at the starting end is the shelling member arranged in the shelling cavity at the starting end. The shelling member at the tail end is the shelling member arranged in the shelling cavity at the tail end. The shelling cavity at the tail end is the shelling cavity connected to the grading roller group at the starting end. The shelling cavity at the tail end is the shelling cavity connected to the grading roller group at the tail end;

[0097] As Figure 15 、 17 shown, the shelling member includes:

[0098] A feeding roller 462, and a feeding part spirally wound around the outer peripheral surface of the feeding roller is provided on the feeding roller;

[0099] A smooth rod 466, one end of the smooth rod is fixedly connected to the side wall of the shelling cavity. The smooth rod is arranged adjacent to the feeding roller and is arranged on one side below the feeding roller;

[0100] A shelling roller 465, the shelling roller is arranged on the side of the smooth rod away from the feeding roller and is arranged on one side above the smooth rod;

[0101] The feeding roller, the smooth rod and the shelling roller are parallel to each other, and the feeding roller, the smooth rod and the shelling roller together form a shelling channel for the eggs to move;

[0102] One end of the smooth rod not connected to the side wall of the shelling cavity forms a discharging port 465 for the eggs to discharge with the side wall of the shelling cavity;

[0103] The shelling gap includes the gap between the feeding roller and the smooth rod, the gap between the smooth rod and the shelling roller, and the gap between adjacent shelling rollers.

[0104] In this embodiment, as Figure 15As shown in the figure, the above-mentioned shelling roller and feeding roller are connected by a power component 463 installed on the side of the box body. The shelling roller and feeding roller are driven to rotate simultaneously by this power component. The power component includes a driving device and a transmission component. The transmission component can adopt a sprocket transmission mechanism, a belt pulley transmission mechanism or other transmission mechanisms that can realize the power transmission between the shelling roller and the feeding roller.

[0105] The principle of this embodiment is:

[0106] The conveying roller group drives the eggs to move towards the grading roller group. When passing through the starting-end grading roller group, the eggs smaller than the grading gap of the starting-end grading roller group will leak out, and the eggs larger than the grading gap of the starting-end grading roller group will move towards the adjacent grading roller group under the action of the starting-end grading roller group. By repeating the above process, the eggs divided into multiple specifications are sent into the corresponding shelling cavities in the shelling device. Since the shelling gap of the shelling component is designed according to the specifications of the eggs, the shelling component will not cause excessive extrusion to the eggs, nor will there be too large a gap with the eggs, so that the eggshells can be better peeled off. The peeled eggshells leak out from the shelling gap, and the shelled eggs are discharged from the discharge port.

[0107] The conveying roller group drives the eggs to move towards the grading roller group. Through the screening and grading of multiple grading roller groups, the eggs are sent to different shelling cavities according to their specifications. The eggs are shelled by a shelling component with a matching shelling gap, so as to realize the simultaneous shelling of eggs of different specifications, improve the efficiency, and avoid the situation of incomplete shelling or incomplete products.

[0108] In this embodiment, as Figure 16 shown, the shelling device further includes:

[0109] A slag discharge port 467, which is arranged corresponding to the lower part of the polished rod;

[0110] A discharge port 468, which is arranged corresponding to the lower part of the discharge port;

[0111] A slag discharge conveyor 464, which is arranged corresponding to the lower part of the slag discharge port 467.

[0112] By setting the slag discharge port and the discharge port, the eggshells and the egg products can be discharged separately, avoiding the eggshells and the egg products being mixed together and difficult to clean. The eggshells are centrally sent to the eggshell collection place through the slag discharge conveyor, so as to facilitate the centralized treatment of the eggshells.

[0113] In this embodiment, the above-mentioned slag discharge port and discharge port are both fixed at the bottom of the box body. The eggs sent into the corresponding shelling cavity in the shelling device can adopt an inclined material distribution channel. By setting the outlet of the material distribution channel above the shelling channel, the graded eggs are respectively sent into different shelling channels in the same shelling cavity.

[0114] Embodiment 2:

[0115] In order to pre - break the eggshell before shelling the poultry egg, as Figures 1 - 3 shown, the automatic poultry egg shelling line further includes a shell - knocking device 420, and the shell - knocking device is connected to the grading device;

[0116] As Figure 7 shown, the shell - knocking device includes:

[0117] A shell - knocking conveyor line 422, which drives the movement of the poultry egg through the shell - knocking conveyor line 422;

[0118] A power device 423, which drives the movement of the shell - knocking conveyor line through the power device;

[0119] A shell - knocking part 427, which is arranged above the shell - knocking conveyor line and drives the shell - knocking part to move vertically back and forth through the power device.

[0120] Drive the shell - knocking conveyor line to move through the power device to send the poultry egg below the shell - knocking part. At the same time, under the action of the power device, the shell - knocking part slides vertically downward to break the eggshell of the poultry egg. After the eggshell is broken, it is easier and more complete for the shelling device to shell the egg.

[0121] In this embodiment, as Figure 10 shown, the shell - knocking device may further include

[0122] A Geneva drive mechanism 425, which is connected to the power input section of the shell - knocking conveyor line;

[0123] An eccentric - wheel connecting - rod drive mechanism 429, which is connected to the power device. The Geneva drive mechanism is connected to the eccentric - wheel connecting - rod drive mechanism through a belt drive or a chain - wheel drive mechanism. The shell - knocking part is connected to the eccentric - wheel connecting - rod drive mechanism through a connecting part 426. As Figure 8 shown, the shell - knocking part is fixedly installed on the connecting part.

[0124] Drive the eccentric - wheel connecting - rod drive mechanism to move through the power rotation, thereby driving the shell - knocking part to move up and down reciprocally. At the same time, drive the Geneva drive mechanism to move under the transmission action of the belt drive or the chain - wheel drive mechanism, so as to make the shell - knocking conveyor line move step - by - step. For example, when the shell - knocking part rises vertically, the shell - knocking conveyor line will drive the poultry egg to move forward a preset distance, and when it moves downward, the shell - knocking conveyor line will stop moving, avoiding the situation of missed knocking. In this embodiment, the Geneva drive mechanism can select a five - division Geneva drive mechanism, or other multi - division Geneva drive structures can also be selected according to the actual situation.

[0125] In this embodiment, as Figure 9As shown, the shell-breaking conveyor line includes a plurality of egg-feeding parts 424, and at least one egg-receiving hole 424A matching the shape of the poultry egg is provided on the surface of the egg-feeding part;

[0126] A egg-supporting part 428 is fixed on the egg-feeding part. The egg-supporting part 428 straddles the egg-receiving hole and is fixed to the egg-feeding part. The egg-supporting part is made of a flexible material.

[0127] Limiting the poultry egg through the egg-receiving hole can prevent the poultry egg from rolling on the shell-breaking conveyor line. Supporting the poultry egg through the egg-supporting part can prevent the poultry egg from leaking out of the egg-receiving hole.

[0128] In this embodiment, the above-mentioned egg-supporting part can be in the shape of a strip as shown in Figure 9 or can also be in the shape of a single-sided or net shape. The material of the egg-supporting part can be made of soft and elastic materials such as leather or rubber.

[0129] When knocking the egg, when the egg-knocking part descends to squeeze the poultry egg, the egg-supporting part can be stretched downward by a certain distance to buffer the impact of the egg-knocking part on the poultry egg within a certain range, so as to prevent the impact of the egg-knocking part on the poultry egg from being too large and damaging the integrity of the poultry egg.

[0130] In this embodiment, as shown in Figure 7 the shell-breaking device further includes a material guide groove 421. A material guide channel corresponding to the above-mentioned egg-receiving hole is provided in the material guide groove 421, and a plurality of poultry eggs are limitedly accommodated in the material guide channel in a single-row linear distribution.

[0131] Temporarily storing the poultry eggs through the material guide groove and guiding them into the egg-receiving hole can prevent the poultry eggs from entering the shell-breaking conveyor line in a disorderly manner, resulting in some poultry eggs not being able to be accommodated in the egg-receiving hole and rolling.

[0132] Embodiment 3:

[0133] To facilitate better detachment of the eggshell of the poultry egg, as shown in Figures 1 - 3 the egg shelling line in this embodiment may further include a cooling device 410, and the cooling device is connected to the shell-breaking device;

[0134] As shown in Figure 4 the cooling device includes:

[0135] A cooling box 411, and the cooling box is limitedly filled with a coolant;

[0136] A first lifting conveyor line 412, the lower part of the first lifting conveyor line is arranged in the cooling box, and the upper part of the first conveyor line is connected to the shell-breaking device 420.

[0137] In this embodiment, the first lifting conveyor is connected to the above-mentioned material guiding trough, and the cooled eggs are conveyed to the guiding channel through the first lifting conveyor.

[0138] By first immersing the cooked eggs in the cooling coolant, since the eggshell membrane and the egg white contract to different degrees when cooled, after being immersed in the coolant, a relatively large gap will be formed between the eggshell membrane and the egg white, thus facilitating the peeling of the eggshell.

[0139] In this embodiment, as Figure 5 shown, there is a sandwich layer 413 in the side wall of the cooling box, and a cooling coil 414 connected to the refrigeration device is arranged in the sandwich layer.

[0140] The refrigerant is input into the cooling coil through the refrigeration device to exchange heat with the coolant in the cooling box, so as to maintain the temperature of the coolant and avoid frequent replacement of the coolant.

[0141] In this embodiment, the coolant can be purified water that has been reduced to a preset temperature.

[0142] As Figure 6 shown, a return trough 415 with an inclined bottom is also arranged below the first lifting conveyor. The return trough is integrally formed with the cooling box and is arranged at the top of one side of the cooling box.

[0143] When the first lifting conveyor lifts and outputs the eggs from the cooling box, the coolant attached to the surface of the eggs drains out from the drainage holes of the first conveyor under the action of gravity, drains into the return trough, and flows back into the cooling box along the bottom of the return trough.

[0144] Embodiment 4:

[0145] Since the shell-breaking device can only break the part of the eggshell in contact with the egg-breaking part and a certain range around it, the rest of the part will still remain intact, which will cause the shell-peeling device to be difficult to peel the eggshell.

[0146] Therefore, to solve this technical problem, as Figures 1 - 3 shown, the egg shelling line in this embodiment may further include a rolling device 440. The rolling device is arranged between the grading device and the shelling device, and the rolling device is arranged corresponding to the grading roller group to receive the eggs discharged from the grading gap;

[0147] As Figure 12 、 13 shown, the rolling device includes:

[0148] A feeding conveyor 441, which is connected to the grading device;

[0149] A rolling conveyor 443, which is arranged above the feeding conveyor;

[0150] A rolling gap is formed between the rolling conveyor and the feeding conveyor, and the rolling gap increases successively from the rolling device at the starting end to the rolling device at the tail end.

[0151] The rolling device at the starting end is a rolling device for receiving eggs discharged from the grading roller group at the starting end, and the rolling device at the tail end is a rolling device for receiving eggs discharged from the grading roller group at the tail end.

[0152] In this embodiment, the rolling conveyor squeezes the eggs and drives them to roll, so as to completely crush the eggshells, which is convenient for peeling the eggshells. By designing multiple rolling devices matching the egg specifications according to the egg specifications, while completely squeezing and breaking the eggshells, it is possible to avoid damage to oversized eggs caused by extrusion or incomplete rolling and breaking of undersized eggs.

[0153] In this embodiment, as Figure 12 shown, two sets of oppositely arranged guide plates 442 are further provided on the feeding conveyor 411. The two sets of guide plates 442 form a guiding channel. The guiding channel is successively divided into a feeding section, a transition section, and a discharging section from the feeding end to the discharging end of the feeding conveyor. The width of the feeding section of the guiding channel is greater than the width of the discharging section, and the transition section linearly narrows from the feeding section to the discharging section. The feeding end of the feeding conveyor is the end connected to the grading device.

[0154] In this embodiment, as Figure 12 、 13 shown, the rolling device may further include two sets of adjusting members. The adjusting members include adjusting rods 444. Rotating the adjusting rods 444 enables the adjusting rods to move vertically. The adjusting rods are connected to the rolling conveyor through connecting shafts 445. The connecting shafts rotate circumferentially relative to the rolling conveyor, and the adjusting rods rotate circumferentially relative to the connecting shafts.

[0155] By rotating the adjusting rods, the height and angle of the rolling conveyor can be adjusted according to the actual use situation, improving the flexibility of the device.

[0156] In this embodiment, the rolling device may further include a rolling frame body 446. The above-mentioned feeding conveyor is fixedly installed on the rolling frame body. The above-mentioned adjusting rods can be threadedly connected to the rolling frame body. When the adjusting rods are rotated, the adjusting rods can linearly move along their own axial directions.

[0157] When the adjusting rods of the two sets of adjusting members are rotated simultaneously, the overall vertical linear movement of the rolling conveyor can be driven, so as to adjust the height of the rolling conveyor according to the actual situation. When one of the adjusting rods of the two sets of adjusting members is rotated, the vertical linear movement of one end of the rolling conveyor can be driven. At this time, the connecting shafts in the two sets of adjusting members will rotate relative to the rolling conveyor, thereby realizing the angle adjustment of the rolling conveyor.

[0158] In this embodiment, a second lifting conveyor line 450 may also be provided between the rolling device and the shelling device. The shelled eggs after rolling are lifted above the box body through this second lifting conveyor line, and a connection is formed between the upper discharge end of the second lifting conveyor line and the shelling channel through a material distribution channel.

[0159] Embodiment 5:

[0160] In order to reduce harmful bacteria on the surface of the eggs, such as Figures 1 - 3 As shown, the egg shelling line in this embodiment may further include an antifoaming device 470, and the antifoaming device is connected to the shelling device;

[0161] As Figure 18 shown, the antifoaming device includes:

[0162] An antifoaming box 471, and the antifoaming box is filled with a limited amount of disinfectant solution;

[0163] A third lifting conveyor line 472, the lower part of the third lifting conveyor line is arranged in the antifoaming box 471, and the upper part extends out of the antifoaming box from the opening of the antifoaming box.

[0164] After the egg shelling is completed, the eggs move into the antifoaming box, and the shelled eggs are disinfected by the disinfectant solution in the antifoaming box, thereby reducing harmful bacteria on the surface of the eggs. The disinfected eggs are lifted out of the antifoaming box through the third lifting conveyor line and sent to the next process.

[0165] In this embodiment, an inclined feed trough is provided on one side of the antifoaming box, and the feed trough is arranged below the discharge port of the above-mentioned shelling device.

[0166] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
