Description

Technical Field

[0001] The invention relates to the technical field of poultry neck processing equipment, and in particular to an automatic grease cleaning device for the surface of poultry necks and a cleaning method thereof. Background Art

[0002] In the process of processing slender poultry necks such as duck necks, in order to improve their edible taste and economic value, it is usually necessary to clean the surface grease after the skinning process is completed. Traditionally, this step relies on manual operation. Although it is time-consuming, labor-intensive and inefficient, it can ensure high product quality. With the advancement of technology, mechanized equipment such as the multi-roller chicken neck peeling machine with application number CN201720266568.7 has been introduced to improve production efficiency. This equipment can be used for cleaning grease on the surface of duck necks. When the equipment is in use, the duck neck is sent into the pressing roller group through a conveyor belt, and the elastic pressing plate is used to apply pressure from the top to make the duck neck close to the rotating pressing roller, and finally the duck skin and grease are removed. This method greatly reduces labor intensity and improves processing speed.

[0003] However, in actual application, it is found that there are still many problems. First, because the duck neck is in the shape of an elongated strip, and the fat on the surface of the duck neck is exposed after the duck skin is detached, the elastic pressing plate directly contacts the fat on the duck neck, and the elastic pressing plate is difficult to effectively limit the duck neck, resulting in poor cooperation, which in turn affects 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 contact the pressing roller, the length of the pressing roller of the peeling machine is set to be no less than the length of the duck neck itself. This makes the pressing roller longer, resulting in insufficient stability during rotation, and easily causing deformation of the pressing roller and increasing the difficulty of processing the pressing roller, further affecting the cleaning effect of the duck neck. Summary of the invention

[0005] The purpose of the present invention is to provide an automatic cleaning device for grease on the surface of poultry necks and a cleaning method thereof, which replaces the manual removal of grease on the surface of duck necks, improves the cleaning effect and operating efficiency, and more importantly, can effectively limit the duck neck through the cooperation of the material hopper and the cleaning module, thereby effectively cleaning the grease, and can maintain the stability of the oiling screw group, reduce the processing difficulty of the oiling screw group, and further improve the cleaning effect.

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

[0007] An automatic grease cleaning device for the surface of poultry necks comprises a frame and a cleaning unit and a conveying unit arranged thereon. The conveying unit is used to assist the feeding and discharging of poultry necks and control the conveying speed of the poultry necks. The cleaning unit is responsible for cleaning the grease on the surface of the poultry necks. The conveying unit comprises a first conveying mechanism, which is laterally arranged 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, on which a plurality of material buckets are arranged, the material bucket above the first conveying mechanism conveys the poultry necks from the back to the front, and a limiting piece is arranged outside the frontmost reversing position of the first conveying mechanism to prevent the poultry necks from escaping, 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 limiter, so that the poultry neck after the reversal can immediately enter the cleaning module, and the cleaning module includes a plurality of cleaning components arranged from front to back, each cleaning component includes a transition piece and an oiling screw group arranged in parallel on the left and right, and the oiling screw groups of two adjacent cleaning components are arranged in a staggered manner, which can clean the grease on the surface of the poultry neck passing above it, so that not only can the grease on the surface of the poultry neck passing above it be effectively processed in sections, but also the necessary supporting force can be provided through the transition piece to avoid any part being suspended in the cleaning process;

[0010] When the cleaning device (an automatic cleaning device for grease on the surface of poultry necks) is used, the poultry neck is placed in a material hopper above a first conveying mechanism, and the poultry neck is conveyed in the material hopper along with the first conveying mechanism, and after the material hopper and the limiter cooperate to complete the reversal, the poultry neck smoothly enters the cleaning module, and finally the grease is cleaned under the coordinated action of the material hopper, the transition piece and the oiling screw group;

[0011] In the above process, the material bucket of the cleaning equipment can not only carry and assist in the transmission of the poultry neck, but also limit the position of the poultry neck when the poultry neck is cleaned of grease and cooperate with the oiling screw group to oil it. Specifically, after the poultry neck is placed in the material bucket and enters the cleaning module with the material bucket, the upper part of the poultry neck is covered by the material bucket, while the lower side is in contact with the transition piece and the oiling screw group for oiling. During this oiling process, the friction and pressure of the material bucket and the oiling screw group act together on the surface of the poultry neck, causing the poultry neck to move slightly between the oiling screw group and the material bucket, thereby effectively removing the grease on the surface of the poultry neck. This design ensures the stability of the poultry neck during the cleaning process, and the material bucket plays a limiting role throughout the process of cleaning the poultry neck, which helps to thoroughly clean the grease on the surface of the poultry neck, and finally obtains a high-quality poultry neck, and its cleaning efficiency and effect are much higher than those of manual labor.

[0012] In addition, the cleaning equipment does not clean the entire poultry neck with grease at one time, but uses staggered oiling screw groups to clean the poultry neck in sections during the transmission process of the poultry neck, so that multiple groups of staggered oiling screw groups act on different sections of the same poultry neck in turn, thereby gradually completing the grease cleaning work of the entire poultry neck. This design shortens the working length of each group of oiling screw groups, reduces the processing difficulty, and improves the stability of the oiling screw groups during operation, thereby improving the cleaning effect of the poultry neck.

[0013] As a preferred implementation method, the shape of the poultry neck is usually an oblong strip. According to its shape and the characteristics of a large amount of exposed grease on the surface, the material hopper is set to be an oblong strip with its length direction perpendicular to the conveying direction, and the depth of the material hopper is set to be no less than the height of a single poultry neck therein. In this way, even during the oiling action, the poultry neck can rotate freely inside the material hopper, which helps to more thoroughly remove the grease on the surface of the entire poultry neck and improve work efficiency. At the same time, since there is appropriate space for the poultry neck to move, the poultry neck will not be forced to be squeezed on the oiling screw group by the material hopper. Therefore, there is no need to worry about the poultry neck being damaged or deformed due to excessive external force. This helps to 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 inclined downward to point to the lower side of the rear end of the cleaning module. After the poultry necks are cleaned of grease, they will be uniformly moved to an operating table located on one side of the oiling equipment, where an operator will stand and perform subsequent processing operations on the poultry necks on the operating table. Since the stability of the equipment is taken into consideration during the design, the frame should not be designed too high. Therefore, the height of the discharge end of the oiling screw group is lower than the operating table. The poultry necks are lifted and conveyed to the operating table by the second conveying mechanism, and the operator does not need to bend down 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 group, so that the poultry neck can move smoothly from the upper side of the transition piece and the oiling screw group. The width of the oiling screw group is not less than 1 / 2 of the width of the cleaning component, and 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 group, so that the material hopper can pass smoothly from the upper side of the transition piece and the oiling screw group to prevent jamming, improve the smoothness of the movement of the cleaning equipment, and ensure that the grease on the surface of the entire poultry neck is cleaned.

[0016] As described above, an automatic grease cleaning device for the surface of poultry necks, the oiling screw group includes a plurality of threaded rods arranged in pairs and rollingly meshing, and the threaded rods are arranged perpendicular to the conveying direction of the poultry neck, the end of the threaded rod close to the transition piece is located on the midline of the conveying direction of the first conveying mechanism, and the end of the threaded rod away from the transition piece is arranged in a suspended state. When working, the meshing part of each threaded rod is in an extrusion state from top to bottom. Under the extrusion and meshing action of the oiling screw group, the grease on the surface of the poultry neck is effectively squeezed and dragged to the bottom of the oiling screw group, thereby completing the cleaning of the poultry neck. In this process, the grease contained in the grease A small amount of oil threads are slowly wrapped around the threaded rod. With the continuous cleaning of multiple poultry necks, more and more oil threads are wrapped around the threaded rod and are difficult to clean. However, one end of the threaded rod is suspended, and the oil threads wrapped around the threaded rod can fall from the suspended end of the threaded rod during the rotation of the threaded rod, or the operator can easily pull the oil threads off from the suspended end. This design greatly facilitates the cleaning of the oil threads wrapped around the threaded rod, ensuring the cleaning effect of the cleaning equipment in continuously cleaning the grease on the poultry necks. A grease collection device is also provided under the threaded rod to collect the cleaned grease.

[0017] As a further implementation method, the frame includes a supporting frame and a turning frame on the upper side thereof, the cleaning unit is arranged on the supporting frame, the first conveying mechanism is arranged on the turning frame, and one side of the turning frame is rotatably connected to the supporting frame, and the other side is detachably connected to the supporting frame, and is provided with a handle. When in use, the operator only needs to hold the handle and gently pull it to easily lift up the turning frame, thereby completely exposing the cleaning unit below, so as to facilitate disassembly and assembly, inspection, cleaning or maintenance of the cleaning unit, especially providing great convenience for the cleaning of the oiling screw group.

[0018] Furthermore, the turning frame includes two side plates arranged opposite to each other, and the first conveying mechanism is a chain conveying mechanism, which is arranged on the inner sides of the two side plates and has two groups respectively. The two ends of the material bucket are respectively connected to the chain links of the two chain conveying mechanism chains. The two groups of chain transmission structures are arranged to improve the stability of the material bucket transmission.

[0019] To facilitate the smooth turning of the poultry neck, the limiting member includes an arc-shaped plate with its opening toward the rear side of the chain conveying mechanism and a horizontal plate tangent to it on its lower side. The vertical distance between the inner sides of the arc-shaped plate and the horizontal plate and the corresponding chain links is greater than the height of the material bucket. Through the cooperation between the material bucket and the limiting member, the poultry neck can smoothly pass through the limiting member to complete the turning without any jamming.

[0020] In order to ensure that the poultry neck can be smoothly transmitted to complete the grease cleaning work, a connecting shaft coaxially connected to it is provided at one end of the threaded rod close to the transition piece. The connecting shaft is rotatably arranged on the support frame through the bearing seat. The transition piece is a U-shaped structure buckled on the bearing seat. The upper horizontal surface of the structure is flush with the upper side of the oiling screw group, and the vertical surfaces on both sides are respectively connected to the front and rear sides of the bearing seat.

[0021] The automatic grease cleaning device for the surface of poultry necks as described above also includes a control unit and a detection mechanism capable of detecting the positions of a material bucket and a poultry neck. The detection mechanism, the first conveying mechanism and the oiling screw group 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 bucket, 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 bucket.

[0022] The above-mentioned cleaning method of the automatic grease cleaning device on the surface of the poultry neck specifically comprises the following steps:

[0023] S1: Control the first transmission mechanism and the oiling screw group to move, the material hopper is transported with the first transmission mechanism at a first preset speed, and the oiling screw group performs oiling at a second preset speed;

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

[0025] S2: Poultry neck grease cleaning;

[0026] S2.1, obtaining a signal from the first detection mechanism, and when it is detected that the material hopper reaches the position of the first detection mechanism, controlling the first transmission mechanism to stop transmission for a first preset time, waiting for manual placement of the poultry neck;

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

[0028] S2.3, obtaining a signal from the second detection mechanism, and when detecting that the height of the poultry neck in the material hopper is greater than the first preset height, controlling the first transmission mechanism to stop transmitting for a second preset time, and waiting for manual adjustment of the poultry neck height;

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

[0030] S2.5. The first transmission mechanism transmits the poultry necks in the material hopper to pass through the limiter and the cleaning unit in sequence, and finally completes the grease cleaning work on the surface of the poultry necks.

[0031] The beneficial effects achieved by the present invention compared with the prior art are:

[0032] 1. The material bucket of this cleaning equipment can not only carry and assist in the transportation of poultry necks, but also cooperate with the oiling screw group to oil the poultry necks, so that the grease is effectively squeezed and dragged to the bottom of the oiling screw group, thereby completing the cleaning work. Its cleaning efficiency and effect are much higher than manual work;

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

[0034] 3. The coordinated design of the material hopper, limiter and oiling module of this cleaning equipment ensures that the poultry neck has appropriate movement space 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 the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0048] Example

[0049] See also Figure 1 , is a structural schematic diagram of an automatic grease cleaning device for the surface of poultry necks of this embodiment, comprising a frame 1 and a conveying unit 2, a cleaning unit 3 and a control unit 5 arranged thereon, the conveying unit 2 comprising 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, and the cleaning unit 3 is responsible for cleaning the grease on the surface of poultry necks.

[0050] Figure 8 and Fig. 9 The frame 1 includes a support frame 11 and a flip frame 12 on its upper side. The first conveying mechanism is transversely arranged on the flip frame 12. The support frame 11 is an L-shaped frame structure, including a first rectangular frame transversely arranged at the lower part and a second rectangular frame arranged at the rear end of the first rectangular frame. The cleaning unit 3 is transversely arranged in the middle of the front end of the first rectangular frame. Two support seats 13 are respectively arranged on the two opposite sides of the front end frame of the first rectangular frame. The flip frame 12 is detachably connected to the first rectangular frame through the support seat 13, and the first rectangular frame and one side of the flip frame 12 are connected to the first rectangular frame and the flip frame 12 through two support seats 13 and 13. The rotating seat 14 connected to the frame 12 is rotatably connected, and a handle 122 is provided on the other side of the flip frame 12. When in use, the operator loosens the connection between the flip frame 12 and the support seat 13, holds the handle 122 and gently pulls it, and the flip frame 12 can be easily opened, thereby completely exposing the cleaning unit 3 below, so as to facilitate the disassembly and inspection or cleaning and maintenance of the cleaning unit 3, and a lock buckle 15 is also provided on the outer side of the support seat 13 on the side where the first rectangular frame is detachably connected to the flip frame 12, and a spring button type latch 16 that can be plugged into the lock buckle 15 is provided on the support seat 13 for easy use.

[0051] Combination Figure 3The first conveying mechanism includes a chain conveying mechanism or a belt conveying mechanism, on which a plurality of material buckets 24 are provided. The material buckets 24 above the first conveying mechanism convey the poultry necks from the back to the front, and a stopper 25 for preventing the poultry necks from escaping is provided on the outer side of the frontmost reversing position of the first conveying mechanism to ensure that the poultry necks can smoothly enter the cleaning unit 3;

[0052] The cleaning unit 3 includes a cleaning module, and the front end of the cleaning module is connected to the lower outlet of the limit member 25, so that the poultry neck can immediately enter the cleaning module after the reversal. The cleaning module includes a plurality of cleaning components arranged from front to back, and each group of cleaning components includes a transition piece and an oiling screw group 34 arranged in parallel on the left and right. The oiling screw groups 34 of two adjacent groups of cleaning components are arranged in a staggered manner, which can clean the grease on the surface of the poultry neck passing above it. This can not only effectively process the grease on the surface of the poultry neck passing above it in sections, but also provide the necessary supporting force through the transition piece 33 to avoid any part being suspended in the air during the cleaning process.

[0053] In addition, the height of the transition piece is not higher than the height of the oiling screw group 34, so that the poultry neck can move smoothly from the upper side of the transition piece and the oiling screw group 34, the width of the oiling screw group 34 is not less than 1 / 2 of the width of the cleaning component, and there is a gap between the lower side of the material hopper 24 located below the first conveying mechanism and the transition piece and the oiling screw group 34, the gap is 3mm-6mm, and the preferred gap is 5mm, so that the material hopper 24 can pass smoothly from the upper side of the transition piece and the oiling screw group 34 to prevent jamming, improve the smoothness of the operation of the cleaning equipment, and ensure that the grease on the surface of the entire poultry neck is cleaned.

[0054] When the cleaning device is in use, the poultry neck is placed in the material hopper 24 above the first conveying mechanism, and the poultry neck is conveyed along with the first conveying mechanism in the material hopper 24. After the material hopper 24 and the limiter 25 cooperate to complete the reversal, the poultry neck smoothly enters the cleaning module, and finally the grease is cleaned under the coordinated action of the material hopper 24, the transition piece and the oiling screw group 34;

[0055] In the above process, the material bucket 24 of the cleaning equipment can not only carry and assist in the transmission of the poultry neck, but also limit the position of the poultry neck when the poultry neck is cleaned of grease and cooperate with the oiling screw group 34 to oil it. Specifically, after the poultry neck is placed in the material bucket 24 and enters the cleaning module with the material bucket 24, the upper part of the poultry neck is covered by the material bucket 24, while the lower side is in contact with the transition piece and the oiling screw group 34 for oiling. During this oiling process, the friction and pressure of the material bucket 24 and the oiling screw group 34 act together on the surface of the poultry neck, causing the poultry neck to move slightly between the oiling screw group 34 and the material bucket 24, thereby effectively removing the grease on the surface of the poultry neck. This design ensures the stability of the poultry neck during the cleaning process, and during the process of cleaning the poultry neck with grease, the material bucket 24 plays a limiting role throughout the process, which helps to thoroughly clean the grease on the surface of the poultry neck, and finally obtains a high-quality poultry neck, and its cleaning efficiency and effect are much higher than those of manual work.

[0056] In addition, the cleaning device does not clean the grease of the entire poultry neck at one time, but uses a staggered oiling screw group 34 to clean the grease of the poultry neck in sections during the transmission process of the poultry neck, so that multiple groups of staggered oiling screw groups 34 act on different sections of the same poultry neck in turn, thereby gradually completing the grease cleaning work of the entire poultry neck. This design shortens the working length of each group of oiling screw groups 34, reduces the processing difficulty, and improves the stability of the oiling screw group 34 during operation, thereby improving the cleaning effect of the poultry neck.

[0057] As a preferred embodiment:

[0058] Combination Figure 4 and Figure 5 Specifically, the first transmission mechanism is configured as follows:

[0059] The turning frame 12 includes two side plates 121 arranged opposite to each other. The first conveying mechanism is a chain conveying mechanism, which is arranged on the inner sides of the two side plates 121 and has two groups respectively. The two ends of the material bucket 24 are respectively connected to the chain links of the two chain conveying mechanism chains 23. The two groups of chain transmission structures are arranged to improve the stability of the material bucket 24 in conveying.

[0060] The two sets of chain transmission mechanisms are driven to move synchronously by a first driving mechanism 22 arranged on one side of the side plate 121. The first driving mechanism 22 includes a transmission shaft 21 rotatably arranged at both ends of the two side plates 121. The transmission shaft 21 is linked to the two chain transmission mechanisms, and a servo motor connected to the transmission shaft 21 located at the front end of the cleaning module is provided on the outer side of one of the side plates 121. The two chain transmission mechanisms are driven to move synchronously by the servo motor to ensure smooth transmission of the material bucket 24.

[0061] Poultry necks, such as duck necks or chicken necks, are all in the shape of long round strips. According to their shape and the characteristics of large amounts of exposed grease on the surface, the material hopper 24 is set to be in the shape of a long strip, with its length direction perpendicular to the conveying direction, and the depth of the material hopper 24 is set to be no less than the height of a single poultry neck therein. In this way, even during the oiling action, the poultry neck can rotate freely inside the material hopper 24, which helps to more thoroughly remove the grease on the surface of the entire poultry neck and improve work efficiency. At the same time, since there is appropriate space for the poultry neck to move, the poultry neck will not be forced to be squeezed on the oiling screw group 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.

[0062] The limiting member 25 includes an arc-shaped plate 251 with an opening toward the rear side of the chain conveying mechanism and a horizontal plate 252 tangent thereto on its lower side. The vertical distance between the inner sides of the arc-shaped plate 251 and the horizontal plate 252 and the corresponding chain links of the chain 23 is greater than the height of the material bucket 24. Through the cooperation between the material bucket 24 and the limiting member 25, the poultry neck can smoothly pass through the limiting member 25 to complete the turning without any jamming. The horizontal plate 252 provides a guiding effect for the poultry neck to enter the oiling screw group 34, so that it can fall onto the oiling screw group 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. The two chain transmission mechanisms are located on the inner side of the end plates 253, and 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.

[0063] Combination Figure 6 and Figure 7 , specifically for the settings of cleaning unit 3:

[0064] The oiling screw assembly 34 is composed of a plurality of threaded rods 341 arranged in pairs and rollingly meshed, and the threaded rods 341 are arranged perpendicular to the conveying direction of the poultry neck. Specifically, one end of each threaded rod 341 close to the transition piece is located on the center line of the conveying direction of the first conveying mechanism, and the end away from the transition piece is arranged in a suspended state.

[0065] In this embodiment, the cleaning assembly is provided with at least two groups, each group of oiling screw groups 34 includes at least six pairs of threaded rods 341, the length of the threaded rods 341 is set to be no less than 1 / 2 of the length of the material hopper 24, and the vertical projection of the material hopper 24 is located on the inner side of the two oiling screw groups 34. Preferably, the length of the threaded rods 341 is 2 / 3-1 / 2 of the length of the material hopper 24.

[0066] One end of the threaded rod 341 close to the transition piece is provided with a connecting shaft 342 coaxially connected thereto, and the connecting shaft 342 is rotatably arranged on the support frame 11 through the bearing seat 31. The transition piece is a U-shaped structure buckled on the bearing seat 31, and its end close to the threaded rod 341 is located on the midline of the transmission direction of the first transmission mechanism, and the upper horizontal surface is flush with the upper side of the oiling screw group 34. The bearing seat 31 is provided with two left and right sides corresponding to the transition piece along the length direction of the connecting shaft 342, and the front and rear vertical surfaces of the transition piece are respectively connected to the front and rear sides of the bearing seat 31.

[0067] The cleaning unit 3 also includes a second driving mechanism 32 located on the left side of the transition piece, and a plurality of threaded rods 341 are transmission-connected with the second driving mechanism 32 and driven to rotate thereby. The second driving mechanism 32 includes a servo motor, and the two threaded rods 341 in each pair of threaded rods 341 are respectively an active threaded rod 341 and a driven threaded rod 341. The output shaft of the servo motor is transmission-connected with the active threaded rod 341 in the pair of threaded rods 341 located in the middle through a chain transmission mechanism. The active threaded rod 341 drives the driven threaded rod 341 meshed with it to rotate, and the driven threaded rod 341 and the threaded rod 341 on the adjacent side thereof are provided with meshing gears, and the driven threaded rod 341 drives the threaded rod 341 adjacent to it to rotate through the gears. At the same time, the active threaded rod 341 and the threaded rod 341 on the adjacent side thereof are provided with meshing gears, and the active threaded rod 341 drives the threaded rod 341 adjacent to it to rotate through the gears. The meshing rotation of each pair of threaded rods 341 is achieved through the above structure, thereby improving the compactness of the device.

[0068] During operation, the meshing parts of the threaded rods 341 are in an extruded state from top to bottom. Under the extrusion 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, thereby completing the cleaning of the poultry neck. During this process, a small amount of oil filaments contained in the grease are slowly wrapped around the threaded rods 341. With the continuous cleaning of multiple poultry necks, more and more oil filaments are wrapped around the threaded rods 341 and are difficult to clean. However, the threaded rods 341 are arranged in a suspended state at one end, and the oil filaments wrapped around the threaded rods 341 can be removed during the rotation of the threaded rods 341. The oil thread can be easily pulled off from the suspended end of the threaded rod 341 by the operator by lifting the turning frame 12 to expose the oiling screw group 34. This design greatly facilitates the cleaning of the oil thread wrapped around the threaded rod 341, thereby ensuring the continuous cleaning effect of the cleaning equipment for the grease on the poultry neck. The design that the turning frame 12 can be lifted up provides great convenience for the cleaning of the oiling screw group 34, and a grease collecting device 35 is provided under the threaded rod 341 for collecting the cleaned grease.

[0069] Combination Figure 2The second conveying mechanism 6 is a belt conveying mechanism connected to the first rectangular frame in the middle, one end of which is located outside the cleaning module, and the other end is inclined downward to point to the lower side of the rear end of the cleaning module. After the grease is cleaned on the poultry necks, they will be uniformly moved to an operating table located on one side of the oiling equipment, where an operator will stand and perform subsequent processing operations on the poultry necks on the operating table. Since the stability of the equipment is taken into consideration during the design, the first rectangular frame should not be designed to be too high. Therefore, the height of the discharge end of the oiling screw group 34 is lower than the operating table. The poultry necks are lifted and conveyed to the operating table by the second conveying mechanism 6, and the operator does not need to bend down to carry them back and forth, which not only saves manpower but also improves work efficiency.

[0070] The cleaning device also includes a control unit 5 and a detection mechanism capable of detecting the position of the material bucket 24 and the poultry neck. The detection mechanism, the first conveying mechanism and the oiling screw group 34 are all communicatively connected to the control unit 5. 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 bucket 24, 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 bucket 24.

[0071] The second detection mechanism is a pair of opposing sensors 4 arranged on the two side plates 121 at the reversing position of the first conveying mechanism, and is used to detect whether the height of the poultry neck in the material hopper 24 exceeds the limit range, so as to prevent the bent poultry neck from entering the limiting member 25 and causing material jam.

[0072] The above-mentioned cleaning method of the automatic grease cleaning device on the surface of the poultry neck specifically comprises the following steps:

[0073] S1: Control the first transmission mechanism and the oiling screw group 34 to move, the material hopper 24 is transported with the first transmission mechanism at a first preset speed, and the oiling screw group 34 performs an oiling action at a second preset speed;

[0074] The second preset speed is greater than the first preset speed;

[0075] S2: Poultry neck grease cleaning;

[0076] S2.1, obtaining a signal from the first detection mechanism, and when it is detected that the material hopper 24 reaches the position of the first detection mechanism, controlling the first transmission mechanism to stop transmission for a first preset time, waiting for manual placement of the poultry neck;

[0077] S2.2, repeat step S2.1;

[0078] S2.3, obtaining a signal from the second detection mechanism, and when it is detected that the height of the poultry neck in the material hopper 24 is greater than the first preset height, controlling the first transmission mechanism to stop transmitting for a second preset time, and waiting for manual adjustment of the poultry neck height;

[0079] S2.4, repeat step S2.3;

[0080] S2.5. The first transmission mechanism transmits the poultry necks in the material hopper 24 to pass through the limiting member 25 and the cleaning unit 3 in sequence, and finally completes the grease cleaning work on the surface of the poultry necks.
