Description

Technical Field

[0001] This invention relates to the field of poultry neck processing equipment technology, specifically to an automatic grease removal device and cleaning method for poultry neck surfaces. Background Technology

[0002] In the processing of long, slender poultry necks such as duck necks, in order to improve their taste and economic value, it is usually necessary to clean the surface grease after the skinning process. Traditionally, this step relies on manual operation, which is time-consuming, labor-intensive, and inefficient, but ensures high product quality. With the advancement of technology, mechanized equipment, such as the multi-roller chicken neck skinning machine with application number CN201720266568.7, has been introduced to improve production efficiency. This equipment can be used for cleaning the grease on the surface of duck necks. When using this equipment, the duck necks are fed into the pressure roller group by a conveyor belt, and pressure is applied from above by an elastic pressure plate, so that the duck necks are pressed tightly against the rotating pressure rollers, and finally the duck skin and grease are removed. This method greatly reduces labor intensity and increases processing speed.

[0003] However, in practical applications, many problems have been found. First, because the shape of the duck neck is an elongated oval, and a lot of oil is exposed on the surface of the duck neck after the duck skin is removed, the elastic pressure plate comes into direct contact with the oil on the duck neck. The elastic pressure plate is difficult to effectively limit the duck neck, resulting in poor coordination and thus affecting the cleaning effect of the duck neck, making it far inferior to the traditional manual cleaning effect.

[0004] Secondly, in order to ensure that the entire duck neck can come into contact with the pressure roller, the length of the pressure roller is set to be no less than the length of the duck neck itself. This results in a relatively long pressure roller, which makes the pressure roller less stable when rotating, and is prone to deformation and increases the processing difficulty of the pressure roller, further affecting the cleaning effect of the duck neck. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic grease removal device and method for poultry necks, which replaces manual removal of grease from duck necks, improves cleaning effect and operational efficiency, and more importantly, can effectively limit the duck neck through the cooperation of the material hopper and the cleaning module, thereby effectively removing the grease. It can also maintain the stability of the oiling screw assembly, reduce the processing difficulty of the oiling screw assembly, and further improve the cleaning effect.

[0006] The technical solution of the present invention is as follows:

[0007] An automatic grease removal device for poultry necks includes a frame and a cleaning unit and a conveying unit mounted on it. The conveying unit is used to assist in the feeding and discharging of poultry necks and to control the conveying speed of the poultry necks. The cleaning unit is responsible for cleaning the grease from the surface of the poultry necks. The conveying unit includes a first conveying mechanism, which is mounted horizontally on the frame above and below the cleaning unit.

[0008] As the core technical concept of the present invention, the first conveying mechanism includes a chain conveying mechanism or a belt conveying mechanism, which is provided with multiple material hoppers. The material hopper above the first conveying mechanism conveys poultry necks from back to front, and a limiting member is provided on the outer side of the foremost reversing position of the first conveying mechanism to prevent poultry necks from detaching, so as to ensure that the poultry necks can smoothly enter the cleaning unit.

[0009] The cleaning unit includes a cleaning module. The front end of the cleaning module is connected to the lower outlet of the limiting component, so that the poultry neck after the reversal can immediately enter the cleaning module. The cleaning module includes multiple sets of cleaning components arranged from front to back. Each set of cleaning components includes a transition component and an oiling screw assembly arranged side by side. The oiling screw assemblies of adjacent sets of cleaning components are staggered, which can clean the grease on the surface of the poultry neck above it. This not only effectively processes the grease on the surface of the poultry neck above it in sections, but also provides the necessary support through the transition component to prevent any part from being suspended in the air during the cleaning process.

[0010] When using this cleaning equipment (an automatic grease removal device for poultry necks), the poultry neck is placed in the material hopper above the first conveying mechanism. The poultry neck is conveyed in the material hopper by the first conveying mechanism. After the material hopper and the limiting component work together to change direction, it smoothly enters the cleaning module. Finally, the grease removal is completed under the synergistic action of the material hopper, the transition component and the oiling screw assembly.

[0011] In the above process, the material hopper of this cleaning equipment not only carries and assists in conveying the poultry neck, but also restricts the position of the poultry neck during grease removal, and works with the oiling screw assembly to apply oil. Specifically, after the poultry neck is placed in the material hopper and enters the cleaning module, the upper part of the poultry neck is covered by the material hopper, while the lower side contacts the transition piece and the oiling screw assembly for oiling. During this oiling process, the friction and pressure of the material hopper and the oiling screw assembly work together on the surface of the poultry neck, causing the poultry neck to move slightly between the oiling screw assembly and the material hopper, thereby effectively removing the grease from the surface of the poultry neck. This design ensures the stability of the poultry neck during the cleaning process, and the material hopper plays a limiting role throughout the grease removal process, which helps to thoroughly remove the grease from the surface of the poultry neck, ultimately obtaining high-quality poultry neck. Its cleaning efficiency and effect are far superior to manual cleaning.

[0012] Furthermore, this cleaning equipment does not clean the entire poultry neck of a single bird in one go. Instead, during the transport of the poultry neck, staggered oiling screw groups are used to clean the poultry neck in sections. Multiple staggered oiling screw groups work on different sections of the same poultry neck in turn, thus gradually completing the grease cleaning of the entire poultry neck. This design shortens the working length of each oiling screw group, reduces the processing difficulty, improves the stability of the oiling screw group during operation, and thus improves the cleaning effect of the poultry neck.

[0013] As a preferred implementation, the poultry neck is typically elongated and cylindrical. Based on its shape and the large amount of exposed surface grease, the material hopper is designed as an elongated strip, with its length perpendicular to the conveying direction. The depth of the material hopper is set to be no less than the height of a single poultry neck within it. This allows the poultry neck to rotate freely inside the material hopper even during the oiling process, facilitating more thorough removal of grease from the entire surface of the neck and improving work efficiency. Simultaneously, because there is adequate space for the poultry neck to move, it is not forcibly pressed against the oiling screw assembly by the material hopper. Therefore, there is no need to worry about the poultry neck being damaged or deformed due to excessive external force, which helps maintain the integrity and overall quality of the poultry neck.

[0014] The conveying unit also includes a second conveying mechanism, one end of which is located outside the cleaning module, and the other end is tilted downwards pointing towards the lower side of the last end of the cleaning module. After the poultry necks have been cleaned of grease, they will be moved to the operating table located on one side of the oiling equipment. The operator stands on the operating table to perform subsequent processing operations on the poultry necks. Due to the consideration of equipment stability during the design, the frame should not be designed too high. Therefore, the height of the discharge end of the oiling screw assembly is lower than the operating table. The second conveying mechanism lifts and conveys the poultry necks to the operating table. The operator does not need to bend over to carry them back and forth, which not only saves manpower but also improves work efficiency.

[0015] Furthermore, the height of the transition piece is not higher than the height of the oiling screw assembly, so that the poultry neck can move smoothly from the top of the transition piece and the oiling screw assembly. The width of the oiling screw assembly is not less than 1 / 2 of the width of the cleaning component. There is a gap between the lower side of the material hopper located below the first conveying mechanism and the transition piece and the oiling screw assembly, so that the material hopper can pass smoothly from the top of the transition piece and the oiling screw assembly, preventing jamming, improving the smoothness of the operation of this cleaning equipment, and ensuring the completion of cleaning the grease on the surface of the entire poultry neck.

[0016] As described above, an automatic grease removal device for poultry necks includes an oiling screw assembly comprising several paired, rollingly meshing threaded rods. The threaded rods are positioned perpendicular to the poultry neck conveying direction. The end of each threaded rod near the transition piece is located on the centerline of the conveying direction of the first conveying mechanism, while the end away from the transition piece is suspended. During operation, the meshing points of the threaded rods are compressed from top to bottom. Under the compressive meshing action of the oiling screw assembly, the grease on the poultry neck surface is effectively squeezed and dragged to the bottom of the oiling screw assembly, thus completing the poultry neck cleaning process. During this process, the grease contains... A small amount of oil strands slowly wrap around the threaded rod. As multiple poultry necks are continuously cleaned, more and more oil strands become entangled on the threaded rod and become difficult to remove. However, the threaded rod is suspended at one end, allowing the oil strands wrapped around it to fall off from the suspended end during the rotation of the threaded rod. Alternatively, the operator can easily pull the oil strands off from the suspended end. This design greatly facilitates the cleaning of oil strands entangled on the threaded rod, ensuring the cleaning effect of this cleaning equipment on continuously removing grease from poultry necks. Furthermore, a grease collection device is installed below the threaded rod to collect the cleaned grease.

[0017] As a further implementation, the frame includes a support frame and a tilting frame on its upper side. The cleaning unit is located on the support frame, and the first conveying mechanism is located on the tilting frame. One side of the tilting frame is rotatably connected to the support frame, and the other side is detachably connected to the support frame. It is also equipped with a handle. When in use, the operator only needs to hold the handle and pull gently to easily lift the tilting frame, thereby fully exposing the cleaning unit below. This facilitates the disassembly, inspection, cleaning, and maintenance of the cleaning unit, which provides great convenience, especially for cleaning the oiling screw assembly.

[0018] Furthermore, the tilting frame includes two side plates arranged opposite each other. The first conveying mechanism is a chain conveying mechanism, which is provided in two sets on the inner side of the two side plates respectively. The two ends of the material hopper are respectively connected to the chain links of the two chain conveying mechanisms. The two sets of chain drive structures are set to improve the stability of material hopper conveying.

[0019] To facilitate the smooth turning of the poultry neck, the limiting component includes an arc-shaped plate with its opening facing the rear of the chain conveyor and a horizontal plate tangent to it on its lower side. The vertical distance between the inner side of the arc-shaped plate and the horizontal plate and the corresponding chain link is greater than the height of the material hopper. Through the cooperation between the material hopper and the limiting component, the poultry neck can smoothly pass through the limiting component to complete the turning without getting stuck.

[0020] To ensure the smooth delivery of grease for cleaning, a connecting shaft is provided at one end of the threaded rod near the transition piece. The connecting shaft is rotatably mounted on the support frame via a bearing seat. The transition piece is a U-shaped structure fastened to the bearing seat, with its upper horizontal surface flush with the upper surface of the grease-applying screw assembly, and its two vertical surfaces connected to the front and rear sides of the bearing seat, respectively.

[0021] The automatic grease removal device for poultry necks described above also includes a control unit and a detection mechanism capable of detecting the position of the material hopper and the poultry neck. The detection mechanism, the first conveying mechanism, and the grease-applying screw assembly are all communicatively connected to the control unit. The detection mechanism includes a first detection mechanism corresponding to the upper rear end of the first conveying mechanism capable of detecting the position of the material hopper, and a second detection mechanism corresponding to the reversing position of the first conveying mechanism capable of detecting the height of the poultry neck in the material hopper.

[0022] The cleaning method of the automatic grease removal device for poultry necks, as described above, specifically includes the following steps:

[0023] S1: Control the first conveying mechanism and the oiling screw assembly to move. The material hopper is conveyed by the first transmission mechanism at a first preset speed, and the oiling screw assembly performs the oiling action at a second preset speed.

[0024] The second preset speed is greater than the first preset speed;

[0025] S2: Cleaning grease from poultry necks;

[0026] S2.1 Obtain the signal from the first detection mechanism. When the material hopper is detected to have reached the position of the first detection mechanism, control the first transmission mechanism to stop conveying for a first preset time and wait for manual placement of the poultry neck.

[0027] S2.2, Repeat step S2.1;

[0028] S2.3 Obtain the signal from the second detection mechanism. When the height of the poultry neck in the material hopper is detected to be greater than the first preset height, control the first transmission mechanism to stop conveying for a second preset time and wait for manual adjustment of the poultry neck height.

[0029] S2.4, Repeat step S2.3;

[0030] S2.5 The first transmission mechanism conveys the poultry necks in the material hopper through the limiting parts and the cleaning unit in sequence, and finally completes the cleaning of the grease on the surface of the poultry necks.

[0031] The beneficial effects of this invention compared to the prior art are as follows:

[0032] 1. The material hopper of this cleaning equipment can not only carry and assist in conveying poultry necks, but also work with the oiling screw assembly to apply oil to poultry necks, so that the grease is effectively squeezed and dragged to the bottom of the oiling screw assembly, thereby completing the cleaning work. Its cleaning efficiency and effect are far superior to manual cleaning.

[0033] 2. This cleaning equipment adopts a segmented grease cleaning method, which shortens the working length of the grease-applying screw assembly, reduces the processing difficulty of the grease-applying screw assembly, thereby improving the stability of the grease-applying screw assembly during operation, and further improving the cleaning effect of poultry necks;

[0034] 3. The design of the material hopper, limiting components, and oiling module of this cleaning equipment ensures that the poultry neck has adequate space to move during the entire conveying and cleaning process. Therefore, there is no need to worry about the poultry neck being damaged or deformed due to excessive external force, which helps to maintain the integrity and overall quality of the poultry neck.

[0047] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings. Example

[0048] See Figure 1 This is a schematic diagram of the structure of an automatic grease removal device for poultry necks according to this embodiment. It includes a frame 1 and a conveying unit 2, a cleaning unit 3 and a control unit 5 mounted thereon. The conveying unit 2 includes a first conveying mechanism and a second conveying mechanism 6, which are used to assist in the feeding and discharging of poultry necks and control the conveying speed of poultry necks. The cleaning unit 3 is responsible for cleaning the grease from the surface of the poultry necks.

[0049] Figure 8 and Figure 9 The frame 1 includes a support frame 11 and a tilting frame 12 on its upper side. A first conveying mechanism is laterally mounted on the tilting frame 12. The support frame 11 is an L-shaped frame structure, including a first rectangular frame laterally mounted at the bottom and a second rectangular frame located at the rear end of the first rectangular frame. The cleaning unit 3 is laterally mounted at the middle of the front end of the first rectangular frame. Two support seats 13 are respectively provided on opposite sides of the front end of the first rectangular frame. The tilting frame 12 is detachably connected to the first rectangular frame through the support seats 13, and the first rectangular frame and the tilting frame 12 are connected by two supports 13 respectively. The rotating seat 14 connected to the frame 12 is rotatably connected. A handle 122 is provided on the other side of the flipping frame 12. When in use, the operator can loosen the connection between the flipping frame 12 and the support seat 13, hold the handle 122 and pull gently to easily lift the flipping frame 12, thereby fully exposing the cleaning unit 3 below, so as to facilitate disassembly, inspection or cleaning and maintenance of the cleaning unit 3. In addition, a latch 15 is provided on the outside of the support seat 13 on the side where the first rectangular frame is detachably connected to the flipping frame 12. A spring button type pin 16 is provided on the support seat 13 that can be plugged into the latch 15 for easy use.

[0050] Combination Figure 3The first conveying mechanism includes a chain conveying mechanism or a belt conveying mechanism, which is equipped with multiple material hoppers 24. The material hoppers 24 above the first conveying mechanism convey poultry necks from back to front, and the outer side of the foremost reversing position of the first conveying mechanism is equipped with a limiting member 25 to prevent poultry necks from detaching, so as to ensure that the poultry necks can smoothly enter the cleaning unit 3.

[0051] The cleaning unit 3 includes a cleaning module. The front end of the cleaning module is connected to the lower outlet of the limiting member 25, so that the poultry neck after the reversal can immediately enter the cleaning module. The cleaning module includes multiple sets of cleaning components arranged from front to back. Each set of cleaning components includes a transition member 33 arranged side by side and an oiling screw group 34. The oiling screw groups 34 of adjacent sets of cleaning components are staggered, which can clean the grease on the surface of the poultry neck above it. This not only effectively processes the grease on the surface of the poultry neck above it in sections, but also provides the necessary support through the transition member 33 to prevent any part from being suspended in the air during the cleaning process.

[0052] Furthermore, the height of the transition piece 33 is not higher than the height of the oiling screw assembly 34, so that the poultry neck can move smoothly from the upper side of the transition piece 33 and the oiling screw assembly 34. The width of the oiling screw assembly 34 is not less than 1 / 2 of the width of the cleaning component. There is a gap between the lower side of the material hopper 24 located below the first conveying mechanism and the transition piece 33 and the oiling screw assembly 34. The gap is 3mm-6mm, preferably 5mm, so that the material hopper 24 can pass smoothly from the upper side of the transition piece 33 and the oiling screw assembly 34, preventing jamming, improving the smoothness of the operation of this cleaning equipment, and ensuring the completion of cleaning the grease on the surface of the entire poultry neck.

[0053] When this cleaning equipment is in use, the poultry neck is placed in the material hopper 24 above the first conveying mechanism. The poultry neck is conveyed in the material hopper 24 with the first conveying mechanism. After the material hopper 24 and the limiting member 25 work together to change direction, the poultry neck smoothly enters the cleaning module. Finally, the grease is cleaned by the coordinated action of the material hopper 24, the transition member 33 and the oiling screw assembly 34.

[0054] In the above process, the material hopper 24 of this cleaning equipment not only carries and assists in conveying the poultry neck, but also restricts the position of the poultry neck during grease removal, and cooperates with the oiling screw assembly 34 to apply oil. Specifically, after the poultry neck is placed in the material hopper 24 and enters the cleaning module, the upper part of the poultry neck is covered by the material hopper 24, while the lower side contacts the transition piece 33 and the oiling screw assembly 34 for oiling. During this oiling process, the friction and pressure of the material hopper 24 and the oiling screw assembly 34 work together on the surface of the poultry neck, causing the poultry neck to move slightly between the oiling screw assembly 34 and the material hopper 24, thereby effectively removing the grease from the surface of the poultry neck. This design ensures the stability of the poultry neck during the cleaning process, and the material hopper 24 plays a limiting role throughout the grease removal process, which helps to thoroughly remove the grease from the surface of the poultry neck, ultimately obtaining a high-quality poultry neck. Its cleaning efficiency and effect are far superior to manual cleaning.

[0055] Furthermore, this cleaning equipment does not clean the entire poultry neck of a single bird in one go. Instead, during the transport of the poultry neck, staggered oiling screw groups 34 are used to clean the poultry neck in sections. Thus, multiple staggered oiling screw groups 34 work in turn on different sections of the same poultry neck, thereby gradually completing the oil cleaning of the entire poultry neck. This design shortens the working length of each oiling screw group 34, reduces the processing difficulty, improves the stability of the oiling screw group 34 during operation, and thus improves the cleaning effect of the poultry neck.

[0056] As a preferred implementation scheme:

[0057] Combination Figure 4 and Figure 5 Specifically, regarding the setup of the first transmission mechanism:

[0058] The tilting frame 12 includes two side plates 121 arranged opposite to each other. The first conveying mechanism is a chain conveying mechanism, which is provided in two sets on the inner side of the two side plates 121 respectively. The two ends of the material hopper 24 are respectively connected to the chain links of the two chain conveying mechanisms 23. The two sets of chain drive structures are set to improve the stability of the material hopper 24 conveying.

[0059] The two sets of chain conveying mechanisms are driven synchronously by a first drive mechanism 22 located on one side of the side plate 121. The first drive mechanism 22 includes a drive shaft 21 rotatably located at both ends of the two side plates 121. The drive shaft 21 is connected to the two chain conveying mechanisms. A servo motor is provided on the outer side of one of the side plates 121 and is connected to the drive shaft 21 located at the front end of the cleaning module. The servo motor drives the two chain conveying mechanisms to move synchronously to ensure the smooth conveying of the material hopper 24.

[0060] Poultry necks, such as duck necks or chicken necks, are long and oval in shape. Based on their shape and the large amount of exposed grease on their surface, the material hopper 24 is designed to be long and narrow, with its length perpendicular to the conveying direction. The depth of the material hopper 24 is set to be no less than the height of a single poultry neck inside. In this way, even during the oiling process, the poultry neck can rotate freely inside the material hopper 24, which helps to more thoroughly remove the grease from the entire surface of the poultry neck and improve work efficiency. At the same time, because there is sufficient space for the poultry neck to move, the poultry neck will not be forcibly squeezed onto the oiling screw assembly 34 by the material hopper 24. Therefore, there is no need to worry about the poultry neck being damaged or deformed due to excessive external force, which helps to maintain the integrity and overall quality of the poultry neck.

[0061] The limiting component 25 includes an arc-shaped plate 251 with its opening facing the rear side of the chain conveyor mechanism and a horizontal plate 252 tangent to it on its lower side. The vertical distance between the inner side of the arc-shaped plate 251 and the horizontal plate 252 and the corresponding chain link 23 is greater than the height of the material hopper 24. Through the cooperation between the material hopper 24 and the limiting component 25, the poultry neck can smoothly pass through the limiting component 25 to complete the turning without jamming. The horizontal plate 252 provides a guiding function for the poultry neck to enter the oiling screw assembly 34, so that it can fall onto the oiling screw assembly 34 more smoothly and accurately. The arc-shaped plate 251 and the horizontal plate 252 are integrally manufactured and formed, and end plates 253 are welded to both ends. Both chain drive mechanisms are located inside the end plates 253. The outer sides of the two end plates 253 are detachably connected to the side plates 121 on the corresponding side through L-shaped connecting plates.

[0062] Combination Figure 6 and Figure 7 Specifically, regarding the settings for cleaning unit 3:

[0063] The oiling screw assembly 34 consists of several threaded rods 341 arranged in pairs and rollingly engaging, with these threaded rods 341 arranged perpendicular to the conveying direction of the conveying mechanism. Specifically, the end of each threaded rod 341 near the transition member 33 is located on the centerline of the conveying direction of the first conveying mechanism, while the end away from the transition member 33 is suspended in the air.

[0064] In this embodiment, the cleaning assembly is provided with at least two sets, and each set of oiling screw assembly 34 includes at least six pairs of threaded rods 341. The length of the threaded rods 341 is set to be not less than 1 / 2 of the length of the material hopper 24, and the vertical projection of the material hopper 24 is located inside the two oiling screw assemblies 34. Preferably, the length of the threaded rods 341 is 2 / 3 to 1 / 2 of the length of the material hopper 24.

[0065] The threaded rod 341 has a connecting shaft 342 coaxially connected to one end near the transition member 33. The connecting shaft 342 is rotatably mounted on the support frame 11 via the bearing seat 31. The transition member 33 is a U-shaped structure fastened to the bearing seat 31. One end of the transition member 33 near the threaded rod 341 is located on the center line of the conveying direction of the first conveying mechanism, and its upper horizontal plane is flush with the upper side of the oiling screw assembly 34. The bearing seat 31 has two bearing seats along the length of the connecting shaft 342 corresponding to the left and right sides of the transition member 33, and the vertical surfaces of the front and rear sides of the transition member 33 are connected to the front and rear sides of the bearing seat 31, respectively.

[0066] The cleaning unit 3 also includes a second drive mechanism 32 located on the left side of the transition piece 33. Several threaded rods 341 are connected to and driven by the second drive mechanism 32. The second drive mechanism 32 includes a servo motor. Two of the threaded rods 341 in each pair are a driving threaded rod 341 and a driven threaded rod 341, respectively. The output shaft of the servo motor is connected to the driving threaded rod 341 in the middle pair of threaded rods 341 through a chain drive mechanism. The driving threaded rod 341 drives the driven threaded rod 341 that meshes with it to rotate. The driven threaded rod 341 and the threaded rod 341 on its adjacent side are provided with gears that mesh with each other. The driven threaded rod 341 drives the threaded rod 341 on its adjacent side to rotate through the gears. At the same time, the driving threaded rod 341 and the threaded rod 341 on its adjacent side are provided with gears that mesh with each other. The driving threaded rod 341 drives the threaded rod 341 on its adjacent side to rotate through the gears. The above structure realizes the meshing and rotation of each pair of threaded rods 341, improving the compactness of the device.

[0067] During operation, the meshing points of the threaded rods 341 are in a state of compression from top to bottom. Under the compression and meshing action of the threaded rods 341, the grease on the surface of the poultry neck is effectively squeezed and dragged to the bottom of the oiling screw assembly 34, thus completing the poultry neck cleaning work. During this process, a small amount of oil strands contained in the grease slowly wrap around the threaded rods 341. As multiple poultry necks are continuously cleaned, more and more oil strands become entangled on the threaded rods 341 and become difficult to clean. However, since one end of the threaded rods 341 is suspended, the oil strands wrapped around the threaded rods 341 can be removed by the rotation of the threaded rods 341. The oil threads fall from the suspended end of the threaded rod 341 during the operation, or the operator can easily pull the oil threads off the suspended end of the threaded rod 341 by lifting the flip frame 12 to expose the oiling screw assembly 34. This design greatly facilitates the cleaning of the oil threads wrapped on the threaded rod 341, ensuring the continuous cleaning effect of the cleaning equipment on poultry neck grease. The flip frame 12 can be lifted, which greatly facilitates the cleaning of the oiling screw assembly 34. In addition, a grease collection device 35 is provided below the threaded rod 341 to collect the cleaned grease.

[0068] Combination Figure 2The second conveying mechanism 6 is a belt conveyor connected to the first rectangular frame in the middle. One end of it is located outside the cleaning module, and the other end is tilted downwards pointing to the lower side of the last end of the cleaning module. After the poultry necks have been cleaned of grease, they will be moved to the operating table located on one side of the oiling equipment. The operator stands and performs subsequent processing operations on the poultry necks on the operating table. Due to the consideration of equipment stability during the design, the first rectangular frame should not be designed too high. Therefore, the height of the discharge end of the oiling screw assembly 34 is lower than the operating table. The poultry necks are lifted and conveyed to the operating table by the second conveying mechanism 6. The operator does not need to bend over to carry them back and forth, which not only saves manpower but also improves work efficiency.

[0069] This cleaning equipment also includes a control unit 5 and a detection mechanism that can detect the material hopper 24 and the position of the poultry neck. The detection mechanism, the first conveying mechanism and the oiling screw assembly 34 are all connected to the control unit 5. The detection mechanism includes a first detection mechanism that can detect the position of the material hopper 24 at the upper rear end of the first conveying mechanism, and a second detection mechanism that can detect the height of the poultry neck in the material hopper 24 at the reversing position of the first conveying mechanism.

[0072] S1: Control the first conveying mechanism and the oiling screw assembly 34 to move. The material hopper 24 is conveyed with the first transmission mechanism at a first preset speed, and the oiling screw assembly 34 performs the oiling action at a second preset speed.

[0073] The second preset speed is greater than the first preset speed;

[0074] S2: Cleaning grease from poultry necks;

[0075] S2.1 Obtain the signal from the first detection mechanism. When the material hopper 24 is detected to have reached the position of the first detection mechanism, control the first transmission mechanism to stop conveying for a first preset time and wait for manual placement of poultry necks.

[0076] S2.2, Repeat step S2.1;

[0077] S2.3 Obtain the signal from the second detection mechanism. When the height of the poultry neck in the material hopper 24 is detected to be greater than the first preset height, control the first transmission mechanism to stop conveying for a second preset time and wait for manual adjustment of the poultry neck height.

[0078] S2.4, Repeat step S2.3;

[0079] S2.5 The poultry necks in the material hopper 24 of the first transmission mechanism pass through the limiting member 25 and the cleaning unit 3 in sequence, and finally complete the cleaning of the grease on the surface of the poultry necks.
