Description

Technical Field

[0001] This utility model relates to the technical field of preserved egg production equipment, and in particular to a mud-coating machine. Background Technology

[0002] Century eggs, also known as preserved eggs or century eggs, are a traditional type of preserved egg product with a unique flavor. The production process is mainly divided into two methods: the traditional mud-wrapping method and the modern soaking method. Among them, mud-wrapping and sawdust coating are key steps in the traditional process.

[0003] Chinese utility model patent CN218977957U, entitled "A Mud-Coating Machine," discloses the following: A conveying mechanism is located on the feeding side of the mud-coating machine; a sliding table is provided between the mud-coating machine and the egg-collecting trough, and the sliding table is fixedly connected inside the mud-coating machine; a mud storage trough is provided at the lower part of the mud-coating machine, and mud slurry is provided in the mud storage trough; a rotating shaft is rotatably connected to the side wall of the mud-coating machine above the mud storage trough, and push rods are welded to the four cardinal directions of the rotating shaft; a motor is fixedly connected to the outer side wall of the mud-coating machine, and the motor is connected to the rotating shaft through a power output shaft; a mud slurry pipe is connected to the bottom of the egg-collecting trough; a mud slurry pump is provided on the mud inlet side of the mud slurry pipe; the mud outlet end of the mud slurry pipe is connected to the mud storage trough; a vertical plate is fixedly connected to one side wall of the egg-collecting trough, and a fixing rod is fixedly connected to the vertical plate; a buffer rod is rotatably connected to the fixing rod. This structure utilizes a mud slurry pump and a mud slurry pipe to automatically recover the mud slurry in the egg-collecting trough into the mud-coating machine for use, providing mechanical conveying that is more convenient and faster.

[0004] The mud-coating process for poultry eggs described in the aforementioned patent utilizes a rotating shaft with push rods within a mud tank. While this simple structure and large spacing between the distributed push rods significantly improve mud-coating efficiency, the large number of eggs undergoing mud-coating inevitably leads to collisions. Combined with the pushing action of the push rods, this causes egg breakage during the mud-coating process, greatly reducing the success rate and increasing production costs. Furthermore, the push rods provide relatively little agitation during mud-coating, causing the mud to settle in the tank after a period of time. This sediment can trap the coated eggs in the settled mud, affecting the normal operation of the rotating shaft and further increasing the egg damage rate.

[0005] Therefore, there is an urgent need for a mud-wrapping machine to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to overcome existing technical problems and provide a mud-coating machine.

[0007] To achieve the above objectives, this utility model is implemented according to the following technical solution: A mud-coating machine includes a frame, a mud-coating trough, an egg conveying mechanism, and a drive mechanism; the mud-coating trough is fixedly installed on the frame, and the drive mechanism drives the egg conveying mechanism to move within the mud-coating trough; The mud-coating trough includes a front sidewall, a rear sidewall, and a connecting curved plate; the front sidewall and the rear sidewall are symmetrically arranged front and rear and are fixedly connected by the connecting curved plate; the connecting curved plate is an integral structure, including a vertical part, an arc part, and an inclined part A; a limiting net is also provided inside the mud-coating trough, the limiting net is an integral structure, including an arc part, an inclined part B, and a material guiding part; The poultry egg conveying mechanism includes a drive sprocket, a driven sprocket A, and a driven sprocket B arranged in an obtuse triangle. The drive sprocket, driven sprocket A, and driven sprocket B are externally meshed with two closed transmission chains, and multiple pushing mechanisms are installed at equal distances between the two closed transmission chains. Driven sprocket A is installed at the lower part of the mud-coating trough. A driving sprocket is installed above driven sprocket A. Driven sprocket B is installed to the upper right of driven sprocket A. The transmission chain that meshes with driven sprocket A is parallel to the vertical part of the connecting bent plate. The transmission chain that meshes with driven sprocket A and driven sprocket B is parallel to the inclined part B of the limiting net. The drive mechanism drives the active sprocket to rotate, which in turn drives the propulsion mechanism to rotate.

[0008] In use, this invention involves filling the mud-coating trough with mud slurry. Eggs fall from the left side of the mud-coating machine onto the pushing mechanism, and then, as the pushing mechanism rotates, they enter the mud-coating trough. After being coated with mud, the eggs are pushed out from the guide section on the right side by the pushing mechanism for the next process. During the mud-coating process, when passing through the vertical section, an adjacent pushing mechanism forms a "cavity" with the vertical section; when passing through the inclined section B, an adjacent pushing mechanism forms a "cavity" with the inclined section B. The eggs are confined within these "cavities," completing the process of the eggs entering the mud-coating trough, rolling and being coated with mud in the slurry, being pushed out of the mud, and being discharged from the mud-coating trough. The pushing mechanism restricts the movement of the eggs throughout the mud-coating process, and the corresponding cavities restrict the mud coating, reducing collisions between eggs and lowering the damage rate.

[0009] The limiting net is designed to allow the eggs to move better in the mud without sinking to the bottom and getting stuck, thus ensuring the smooth process of being coated in mud.

[0010] The driving sprocket, driven sprocket A, and driven sprocket B used in this invention are all existing technologies. Their specific structure includes two single sprockets fixedly connected by a rotating shaft. The driving sprocket is driven to rotate by a motor, which in turn drives the chain around the driving sprocket, driven sprocket A, and driven sprocket B to rotate, causing the pushing mechanism on the chain to rotate sequentially.

[0011] The chain and sprocket drive mechanism of this invention is existing technology. Therefore, other components involved in the chain and sprocket drive can be added according to actual usage requirements, such as tensioners.

[0012] The spacing between the end of the pushing mechanism and the vertical, arc-shaped, and inclined portions B of this invention is set according to the type of poultry egg being processed. This ensures smooth operation of the pushing mechanism while preventing the eggs from falling through the gaps. Specifically, the spacing can be 1-3 cm. The uppermost part of the vertical portion does not exceed the height of the drive sprocket's shaft, facilitating entry into the mud-coating machine from the left side.

[0013] Preferably, the angle between the transmission chain that meshes with driven sprockets A and B and the horizontal plane is 30-60 degrees.

[0014] Preferably, the pushing mechanism includes a bending plate and a connecting plate; the bending plate is an integral L-shaped bending plate, including a horizontal plate and a vertical plate; multiple grout leakage holes A are distributed at equal intervals from front to back on the horizontal plate, and multiple grout leakage holes B are distributed at equal intervals from front to back on the vertical plate; A connecting plate is symmetrically installed on both the front and back sides of the lower end face of the horizontal plate. The connecting plate is an L-shaped folding plate. The pushing mechanism is connected to the transmission chain through the connecting plate.

[0015] Specifically, the connection between the connecting plate and the transmission chain is existing technology, and those skilled in the art can install it according to actual usage requirements.

[0016] The transmission chain consists of multiple inner chain plates, multiple outer chain plates, multiple pins, multiple sleeves, and multiple rollers. When the driving mechanism is connected to the transmission chain, it is only necessary to replace the outer chain plate at the connection point with the connecting plate of the driving mechanism. The connecting plate is provided with through holes that match the two adjacent inner chain plates for the pins to pass through.

[0017] Preferably, the pushing mechanism further includes an extension plate, which is detachably fixed to the right side of the vertical plate; the extension plate has multiple slurry leakage holes C evenly distributed from front to back.

[0018] For detachable connections, any commonly used type in this field can be selected, such as screw or bolt fastening connections.

[0019] Preferably, the pushing mechanism further includes stop levers, and several stop levers are detachably fixedly installed on the front and rear sides of the horizontal plate.

[0020] The main purpose of the pushing mechanism in this invention is to both propel the eggs and limit their movement. Therefore, the size of the slurry leakage holes on the entire pushing mechanism must be large enough to allow slurry to leak out while preventing the corresponding eggs from leaking out. The same applies to the baffle; the baffle is designed to block the eggs and prevent them from leaking out from both ends of the horizontal plate.

[0021] Similarly, the spacing between adjacent push mechanisms (the spacing here refers to the spacing when the drive chain is straight) also needs to match the eggs to prevent them from leaking out from both ends.

[0022] The propulsion mechanism also serves to agitate the mud in the mud-coating tank, making the mud more uniform and reducing the deposition of solid materials in the mud.

[0023] Preferably, the bottom of the mud-coating trough is provided with a discharge hole, and a discharge pipe with a valve is connected to the outside of the discharge hole.

[0024] Preferably, a material guide trough is fixedly installed on the mud-coating trough.

[0025] The feed guide chute extends into the mud-coating chute from the rear side at an angle from top to bottom, and the position of the feed guide chute avoids the poultry egg conveying mechanism, so as not to hinder the smooth operation of the poultry egg conveying mechanism.

[0026] The feed chute is connected to a storage tank containing mud via a flexible screw conveyor. The mud in the storage tank is transported to the mud-coating trough via the feed chute through the flexible screw conveyor. The flexible screw conveyor is existing technology, and those skilled in the art can select its model according to actual usage requirements.

[0027] Components not specified in this invention are all made using conventional methods in the field. Those skilled in the art can select their models and installation methods according to actual usage needs, and clearly understand how to install and control them. They will not be described in detail here.

[0028] This utility model is a mud-coating machine, which is mainly used to coat poultry eggs with mud. The feed end and discharge end of the mud-coating machine can be equipped with corresponding egg feeding mechanism, sawdust coating mechanism, etc., according to actual use needs, such as the egg feeding mechanism and sawdust coating mechanism described in publication number CN205648894U.

[0029] The beneficial effects of this utility model are: This invention has a simple structure. The pushing mechanism restricts the movement of the poultry eggs throughout the mud coating process, and the mud coating of the poultry eggs is restricted by corresponding cavities, which reduces the collision between poultry eggs and reduces the damage rate of poultry eggs. The setting of the pushing mechanism also plays a role in disturbing the mud in the mud coating tank, which can make the mud more uniform and reduce the deposition of solid materials in the mud.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0033] Example 1 like Figures 1 to 6 As shown, a mud-coating machine includes a frame 1, a mud-coating trough 2, an egg conveying mechanism, and a drive mechanism; the mud-coating trough is fixedly installed on the frame, and the drive mechanism drives the egg conveying mechanism to move within the mud-coating trough; The mud-coating trough includes a front sidewall 3, a rear sidewall 4, and a connecting curved plate; the front sidewall and the rear sidewall are symmetrically arranged front and rear and are fixedly connected by the connecting curved plate; the connecting curved plate is an integral structure, including a vertical part 5, an arc part 6, and an inclined part A7; a limiting net is also provided inside the mud-coating trough, the limiting net is an integral structure, including an arc part 8, an inclined part B9, and a material guiding part 10; The poultry egg conveying mechanism includes a drive sprocket 11, a driven sprocket A12, and a driven sprocket B13 arranged in an obtuse triangle. The drive sprocket, driven sprocket A, and driven sprocket B are externally meshed with two closed transmission chains 14. Multiple pushing mechanisms are installed at equal intervals between the two closed transmission chains. Driven sprocket A is installed at the lower part of the mud-coating trough. A driving sprocket is installed above driven sprocket A. Driven sprocket B is installed to the upper right of driven sprocket A. The transmission chain that meshes with driven sprocket A is parallel to the vertical part of the connecting bent plate. The transmission chain that meshes with driven sprocket A and driven sprocket B is parallel to the inclined part B of the limiting net. The drive mechanism 15 drives the active sprocket to rotate, which in turn drives the push mechanism to rotate; the drive mechanism is a motor.

[0034] The transmission chain that meshes with driven sprockets A and B forms an angle of 45 degrees with the horizontal plane.

[0035] The pushing mechanism includes a bending plate and a connecting plate 16; the bending plate is an integral L-shaped bending plate, including a horizontal plate 17 and a vertical plate 18; multiple grout leakage holes A19 are distributed at equal intervals from front to back on the horizontal plate, and multiple grout leakage holes B20 are distributed at equal intervals from front to back on the vertical plate. A connecting plate is symmetrically installed on both the front and back sides of the lower end face of the horizontal plate. The connecting plate is an L-shaped folding plate. The pushing mechanism is connected to the transmission chain through the connecting plate.

[0036] The transmission chain consists of multiple inner chain plates 21, multiple outer chain plates 22, multiple pins 23, multiple sleeves, and multiple rollers. When the driving mechanism is connected to the transmission chain, it is only necessary to replace the outer chain plate at the connection point with the connecting plate of the driving mechanism. The connecting plate is provided with through holes that match the two adjacent inner chain plates for the pins to pass through.

[0037] The pushing mechanism also includes an extension plate 24, which is detachably fixed to the right side of the vertical plate by screws and nuts; multiple grout leakage holes C25 are distributed at equal intervals from front to back on the extension plate.

[0038] The pushing mechanism also includes two stop rods 26, both of which are screw rods and are detachably fixed to the front and rear sides of the horizontal plate by nuts.

[0039] The bottom of the mud-coating trough is provided with a discharge hole 27, and a discharge pipe with a valve is connected to the outside of the discharge hole.

[0040] In this embodiment, mud slurry is injected into the mud-coating trough. Poultry eggs can fall from the left side of the mud-coating machine onto the pushing mechanism. Then, as the pushing mechanism rotates, they enter the mud-coating trough. After being coated with mud in the mud-coating trough, the eggs are pushed out from the guide section on the right side by the pushing mechanism to proceed to the next process.

[0041] During the mud-coating process, when passing through the vertical section, an "enclosure" is formed between the adjacent pushing mechanism and the vertical section. In this section, the egg is supported by the end face of the extension plate and smoothly enters the mud. When passing through the curved section, the pushing mechanism below the egg first restricts the position of the egg. Then, as the pushing mechanism passes around the driven sprocket A, the egg falls to the bottom of the mud-coating trough and is pushed by the pushing mechanism behind the egg, thus transitioning to the inclined section B. When passing through the inclined section B, an "enclosure" is formed between the adjacent pushing mechanism and the inclined section B. In this position, the egg is lifted by the extension plate of the pushing mechanism on the left. Throughout the process, the egg is confined within the aforementioned "enclosure," completing the process of the egg entering the mud-coating trough, rolling and being coated in the mud within the mud-coating trough, being pushed out of the mud, and being discharged from the mud-coating trough.

[0042] In this embodiment, the distance between the end of the pushing mechanism and the vertical, arc-shaped, and inclined portions B is set according to the type of poultry egg being processed. This ensures smooth operation of the pushing mechanism while preventing the egg from falling through the gaps. Specifically, the distance can be 3cm. The uppermost part of the vertical portion does not exceed the height of the drive sprocket's shaft, facilitating entry into the mud-coating machine from the left side.

[0043] Example 2 like Figures 7 to 9 As shown, a material guide trough 28 is fixedly installed on the mud-coating trough.

[0044] The feed guide chute extends into the mud-coating chute from the rear side at an angle from top to bottom, and the position of the feed guide chute avoids the poultry egg conveying mechanism, so as not to hinder the smooth operation of the poultry egg conveying mechanism.

[0045] The feed chute is connected to the storage tank containing mud via a flexible screw conveyor. The mud in the storage tank is transported to the mud-coating chute via the feed chute through the flexible screw conveyor.

[0046] The technical solution of this utility model is not limited to the specific embodiments described above. All technical modifications made based on the technical solution of this utility model shall fall within the protection scope of this utility model.
