Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 6 , the present invention provides a technical solution: an intelligent integrated egg washing machine conveying device, including a processing box 1, one end of the top of the processing box 1 is slidably connected with a roller brush 3 through a cylinder 2, the inner wall of the processing box 1 is rotatably connected with a first operation area 4 below the corresponding roller brush 3, one end of the first operation area 4 is rotatably connected with a second operation area 5, one end of the second operation area 5 is rotatably connected with a third operation area 6, the second operation area 5 is located between the first operation area 4 and the third operation area 6, guiding supports 7 are fixedly connected at the joints between the first operation area 4 and the second operation area 5 and between the second operation area 5 and the third operation area 6, a surface treatment assembly 8 is arranged above the corresponding third operation area 6 on the inner wall of the processing box 1, the first operation area 4, the second operation area 5 and the third operation area 6 are all composed of a transmission assembly 9 and a bracket 10, an ultraviolet disinfection lamp strip 11 is fixedly connected to the inner top wall of the processing box 1 above the corresponding second operation area 5, a fan 12 is fixedly connected to the inner top wall of the processing box 1 above the corresponding third operation area 6, and a quick-release panel 13 is rotatably connected to the outer wall of the processing box 1 on the side of the cavity where the first operation area 4 is located.

[0025] The surface treatment assembly 8 is composed of a drying brush 801, a synchronous pulley 802 and a toothed belt 803. The shaft head of the drying brush 801 penetrates through the axis of the synchronous pulley 802 and forms an integral connection. The synchronous pulleys 802 are distributed up and down and are connected by a toothed belt 803 covering and meshing on the outside thereof. A first bevel gear 804 and a second bevel gear 805 are respectively rotatably connected above the drying brush 801. The first bevel gear 804 and the second bevel gear 805 are vertically distributed and meshed, and the first bevel gear 804 is coaxially connected with the synchronous pulley 802 located above.

[0026] The transmission assembly 9 is composed of a driving sprocket 901, a driven sprocket 902 and a chain 903. The driving sprocket 901 and the driven sprocket 902 are connected by a chain 903 that wraps around and meshes with their exteriors.

[0027] In this embodiment, as Figure 2 and Figure 3 shown, the processing tank 1 is provided with liquid inlet pipes above the corresponding first operation area 4 and second operation area 5. One end of the liquid inlet pipe penetrates through the processing tank 1 and extends to the outside. A plurality of nozzles are provided below the pipe body of the liquid inlet pipe inside the processing tank 1. A liquid discharge nozzle is opened on one side of the outer wall of the processing tank 1 corresponding to one side of the first operation area 4 and the second operation area 5. At the same time, the bottom wall of the processing tank 1 corresponding to the first operation area 4 and the second operation area 5 is in a slope shape, and the liquid discharge nozzle is located at the end with a lower slope; a plurality of nozzles are provided below the pipe body of the liquid inlet pipe inside the processing tank 1. In the first operation area 4, the eggs initially placed can be pre-cleaned to wash off most of the obvious stains on the surface; in the second operation area 5, it can cooperate with the inclined structure to make the sprayed liquid fully cover the eggs, improve the cleaning and disinfection effects, realize the staged use of different property liquids, improve the cleaning and disinfection efficiency, and ensure that the best effects can be achieved in each link.

[0028] In this embodiment, as Figure 1 and Figure 2 shown, the quick-release panel 13 is composed of a plate body and a rubber body. A rubber strip is wrapped around the position where the quick-release panel 13 fits the processing tank 1. One end of the quick-release panel 13 is provided with a threaded through hole, and a through hole with the same specification is opened on the outer wall of the processing tank 1 at the corresponding position. The two are connected by a quick-release bolt in a threaded manner; since the stains generated by the first flushing of the eggs are the most, after the discharge of the sewage medium is completed, the quick-release panel 13 is connected by a quick-release bolt and can be quickly opened, which enables the operator to clean the area of the processing tank 1 corresponding to the first operation area 4 in time, avoiding the accumulation of a large amount of stains and affecting the subsequent operation of the equipment and the egg washing effect. The rubber strip has good elasticity and sealing performance, can fill the gap between the quick-release panel 13 and the processing tank 1, effectively prevent the cleaning liquid from seeping out of the gap, and avoid the pollution of the surrounding environment of the equipment caused by liquid leakage.

[0029] In this embodiment, as Figure 2 、 Figure 3 and Figure 6As shown, the second operating area 5 is inclined. The higher end of the second operating area 5 is arranged below the guiding support 7 between it and the first operating area 4, and the lower end of the second operating area 5 is arranged above the guiding support 7 between it and the third operating area 6. Moreover, the spray head and the ultraviolet disinfection lamp strip 11 below the drain pipe provided corresponding to the second operating area 5 of the processing box 1 are arranged corresponding to the inclination angle of the second operating area 5; the inclined second operating area 5 cooperates with the white vinegar solution sprayed by the spray head to form a continuous and efficient flushing effect. The cleaning liquid flowing down from the high place is in full contact with the egg surface, taking away dirt, ensuring that each egg can be comprehensively and thoroughly cleaned, improving the cleaning efficiency. The sewage and impurities after cleaning quickly flow to the drain pipe along the inclined surface, reducing the residence time and residue amount of dirt on the egg surface and inside the equipment, reducing the risk of secondary pollution, ensuring the cleanliness of the eggs. The ultraviolet disinfection lamp strip 11 is arranged along the inclination angle of the second operating area 5, ensuring that during the egg transportation process, ultraviolet light can evenly and vertically irradiate each part of the egg. Compared with horizontal irradiation, this method can reduce the irradiation dead angle, make the disinfection more comprehensive, effectively kill bacteria and viruses, and improve the hygienic safety of the eggs.

[0030] In this embodiment, as Figure 4 shown, the transmission components 9 are distributed in groups of two at both ends of the bracket 10. And the bracket 10 is composed of a shaft rod and a conical structure fixed in the middle of the shaft rod. The surface of the conical structure is wound with a rubber layer. The bracket 10 is annularly distributed and is fixedly connected to the chain 903 of the transmission components 9 at both ends through a pin shaft. And the transmission components 9 are connected by the driving sprockets 901 connected coaxially; the conical structure in the middle of the bracket 10 can well fit the shape of the egg, providing stable support for the egg. Even if it falls out, it can be stuck in the interval formed by the two conical structures, enabling the center of gravity of the egg to be effectively controlled, reducing the risk of shaking, rolling or even falling during transportation, and ensuring the integrity of the egg to the greatest extent. The rubber layer coated on its surface can effectively absorb and disperse the energy generated by vibration and collision, preventing the egg from being damaged by excessive impact force.

[0031] In this embodiment, as Figure 1 shown, the drying brush 801 makes a relative rotational movement through the first bevel gear 804 and the second bevel gear 805; the relative rotational movement enables the drying brush 801 to cover multiple parts of the egg surface, ensuring the overall cleanliness and dryness of the egg surface, which helps to more effectively remove the remaining moisture on the egg surface.

[0032] In this embodiment, as Figure 1 and Figure 2As shown in the figure, several feeding areas spliced by rods are arranged on the inner wall of the processing box 1 below the corresponding roller brush 3. There are three roller brushes 3, which are connected by belts wrapped around the outer part of the shaft head. And a baffle is arranged at one end of the feeding area adjacent to the first operating area 4. There are gaps between the baffles, and the specifications of the gaps are the same as the length of the conical structure on the surface of the bracket 10 in the first operating area 4; the baffle prevents the eggs from falling, ensuring that the eggs are always in a safe position in the feeding area before being put in. The roller brushes 3 form an array of cleaning areas, covering a larger area of the egg surface, improving the pre-cleaning efficiency. Its material is soft and has good elasticity, which can fit the curved surface of the egg for gentle brushing, avoiding mechanical damage to the eggshell surface and reducing the risk of cracks or breakage.

[0033] The usage method and advantages of the present utility model: For this intelligent integrated egg washing machine conveying device, during use, the working process is as follows:

[0034] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown in the figure, first, the liquid inlet pipes of the processing tank 1 corresponding to the first operation area 4 and the second operation area 5 are respectively connected to the purified water supply device and the white vinegar solution disinfectant supply device made by mixing white vinegar and purified water. The operator places the eggs to be processed in the feeding area of the processing tank 1 corresponding to the first operation area 4. Before the equipment is started, the roller brush 3 can be lowered to an appropriate position through the cylinder 2 in advance, and unnecessary extrusion of the eggs is ensured. The roller brush 3 is made of sponge material and rotates slowly and evenly synchronously through the stepping motor. After pre-treating the stains attached to the egg surface, after the stain treatment is completed, the roller brush 3 is lifted again through the cylinder 2. The operator places the eggs one by one on the bracket 10 with a conical shape and a rubber layer wound on the surface that is driven on the surface of the first operation area 4. The bracket 10 moves in a circular motion by means of the transmission of the chain 903. The eggs start from the first operation area 4 with the movement of the bracket 10 and transition to the second operation area 5 through the guiding bracket 7. In the second operation area 5, the liquid inlet pipe sprays the white vinegar solution on the egg surface through the nozzle for disinfection treatment. At the same time, the ultraviolet disinfection lamp strip 11 irradiates the eggs with ultraviolet light for disinfection. The eggs then transition to the third operation area 6 through the transmission of the second operation area 5 and the guiding bracket 7 between the second operation area 5 and the third operation area 6. In the third operation area 6, the coaxially connected second bevel gear 805 rotates under the drive of the servo motor, driving the two meshing first bevel gears 804 to rotate relatively. The synchronous pulley 802 coaxial with the first bevel gear 804 rotates, and drives the synchronous pulley 802 coaxially connected to the drying brush 801 below to move relatively through the toothed belt 803, so that the drying brush 801 realizes a relative rotational motion. The drying brush 801 is made of bristle brush, which is soft and has a certain water absorption. The blower 12 provided corresponding to the upper part of the third operation area 6 on the inner top wall of the combined processing tank 1 dries the surface of the eggs. The eggs processed in the third operation area 6 will be conveyed to the external platform, and the operator can pick them up and enter the next link. During the processing of the eggs, impurities such as sewage and sediment will be generated under the scouring of media such as white vinegar solution and purified water. The bottom walls of the processing tank 1 corresponding to the first operation area 4 and the second operation area 5 are both sloped, and drain nozzles are opened on the outer walls of the corresponding sides, which can effectively discharge the media. At the same time, a quick-release panel 13 is additionally provided at the position corresponding to the first operation area 4. The impurities such as sediment will gather at the lower end of the slope under the scouring of the media. After the quick-release panel 13 is opened, it can be cleaned from the entrance.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model.
