Description

Technical Field

[0001] This invention relates to the field of descaling technology, and in particular to an adaptive clamping hydraulic descaling device and method for fish. Background Technology

[0002] During fish processing, scales need to be removed to facilitate further refrigeration or cooking. Scales are typically removed manually, but this method is slow and has a low cleaning rate, making it unsuitable for mass processing and production of fish products; especially at higher temperatures, it makes the processed fish more prone to spoilage.

[0003] Currently, common fish descaling devices require water rinsing during operation to effectively remove scales and prevent scale residue from remaining on the fish's surface. However, because the angle of the water pipes is usually fixed, the rinsing area is also fixed. Therefore, when rinsing fish of different sizes and types, the devices can only rinse specific areas, resulting in ineffective all-around rinsing of the fish and a lack of overall flexibility. Consequently, the processed fish often has a lot of scales attached to its surface. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides the following technical solution: An adaptive clamping hydraulic fish scale removal device includes an outer shell, a feed inlet opened on the side wall of the outer shell, a support set in the inner cavity of the outer shell, a first body set inside the support, and a second body distributed on one side of the first body. A support is fixed on one side of the top of the first body, and a transmission structure is provided on one side of the support. The output end of the transmission structure is connected to a transmission shaft, and the other end of the transmission shaft is connected to a rotating arm. A linkage plate is connected to one side of the other end of the rotating arm, and a movable rod is connected to the bottom of the linkage plate. A water supply pipe is connected to the inner side of the other end of the movable rod, and a nozzle is provided at one end of the water supply pipe. A rotating seat is connected to the other end of the water supply pipe.

[0005] Preferably, the transmission structure includes a first motor, a driving gear, and a driven gear. The first motor is fixed to one side of the top of the first body, and the output end of the first motor is connected to the driving gear. The driven gear is meshed with one side of the driving gear, and the center of one side of the driven gear is fixedly connected to the transmission shaft.

[0006] Preferably, a second motor is distributed on one side of the first motor, and the output end of the second motor is connected to a rotating shaft, the bottom of the rotating shaft is connected to a transmission roller, and a conveyor belt is sleeved on the outer ring surface of the transmission roller.

[0007] Preferably, a third motor is fixedly mounted on one side of the top of the bracket, and a rotating seat is provided at the bottom of the third motor. A first pulley is distributed on one side of the rotating seat. A support side plate is welded to the side wall of the bracket, and a second pulley is rotatably connected to the inner wall of the support side plate. A pull rope is sleeved on the outer surface of the rotating seat. A bending rod is welded to one side of the bottom of the first body, and a tension spring is connected to the outer bottom of the bending rod.

[0008] Preferably, a connecting plate is rotatably connected to one side wall of the first body, and a linkage shaft passes through the inner side of one end of the connecting plate, with a toothed plate sleeved on the outer side of the bottom of the linkage shaft.

[0009] Preferably, the outer ring surface of the driving gear has multiple teeth arranged equidistantly along the center point, and the driving gear and the driven gear are meshed together through the teeth.

[0010] Preferably, the drive shaft and the rotating arm are fixedly connected, and a groove is provided at one end of the rotating arm near the linkage plate, and a protrusion is provided at one end of the linkage plate extending into the groove to form a sliding connection with one end of the rotating arm.

[0011] Preferably, the other end of the linkage plate is rotatably connected to the movable rod via a shaft, and the water supply pipe passes through the inside of the movable rod.

[0012] Preferably, the first pulley is rotatably connected to the bracket via a bearing seat, and the first pulley is obliquely symmetrically distributed along the vertical center line of the bracket.

[0013] Preferably, one end of the rotating shaft is connected to the output end of the second motor, while the other end of the rotating shaft is detachably connected to the transmission roller, and the rotating shafts are arranged in parallel. There are two transmission rollers, which are arranged in parallel, and the two transmission rollers are respectively connected to the output end of the second motor and the bottom of one end of the second body through the rotating shaft.

[0014] As an improvement to the above technical solution, the structure of gears, rotating arms, linkage plates and movable rods can be set up to facilitate the adjustment of the nozzle position and angle according to the actual use needs during the subsequent fish scale removal process. This allows for effective spraying treatment of the fish surface, preventing the existence of spray dead zones that would result in a large number of fish scales remaining on the fish surface afterward, thus improving overall practicality.

[0015] An adaptive clamping hydraulic descaling method for fish includes the following steps: Step 1: The fish to be descaled is transported to the inside of the outer shell through the inlet on the side wall. As the fish is fed in, the angle of the first and second machines on both sides can be adjusted to better clamp the fish. At this time, the second motor is powered on and the shaft connected to its output end rotates. The rotation of the shaft drives the transmission roller connected to its output end to rotate as well. The rotation of the transmission roller, in turn, moves the conveyor belt on its outer surface. The synchronous movement of the two conveyor belts together can realize the conveying and processing of the fish, which is convenient for the subsequent descaling process. Step 2: When the spray angle of the nozzle needs to be adjusted according to actual usage requirements, the first motor will cause the drive gear connected to its output end to rotate. The rotation of the drive gear will then cause the driven gear meshing with it to rotate. Since the driven gear and the drive shaft are fixedly connected, the drive shaft can be moved as the driven gear rotates. At this time, the rotation of the drive shaft will drive the rotating arm to rotate as well. Step 3: Since one end of the rotating arm is slidably connected to the linkage plate, the movement of the rotating arm can drive the movement of the linkage plate. At this time, the linkage plate will move longitudinally under the action of the rotating arm, and then the longitudinal movement of the linkage plate can pull the movable rod, and then the movement of the movable rod can be used to pull the water pipe. Step 4: At this point, one end of the water supply pipe will rotate along one side of the bottom of the machine via the rotating base to adjust the angle of the water supply pipe. This facilitates better adjustment of the nozzle position by utilizing the movement of the water supply pipe. The nozzle adjustment is used to effectively remove scales from the surface of the fish, while also improving the flexibility of the entire device.

[0016] The beneficial effects of this invention are: This invention, through its structure including gears, rotating arms, linkage plates, and movable rods, allows for adjustment of the nozzle's position and angle during fish scaling according to actual usage needs. This enables comprehensive and effective spraying of the fish's surface, preventing any spraying dead zones and enhancing overall practicality. Attached Figure Description

Detailed Implementation

[0019] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0020] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 An adaptive clamping hydraulic fish scale removal device includes an outer shell 1, a feed inlet 2 opened on the side wall of the outer shell 1, a support 3 disposed in the inner cavity of the outer shell 1, a first body 4 disposed inside the support 3, and a second body 5 distributed on one side of the first body 4. A support 6 is fixedly provided on one side of the top of the first body 4, and a transmission structure is provided on one side of the support 6. The output end of the transmission structure is connected to a transmission shaft 10, and the other end of the transmission shaft 10 is connected to a rotating arm 11. The transmission shaft 10 and the rotating arm 11 are fixedly connected. A sliding groove is provided at one end of the rotating arm 11 near the linkage plate 12, and a protrusion is provided at one end of the linkage plate 12 extending into the sliding groove to form a sliding connection with one end of the rotating arm 11. The other end of the rotating arm 11 is connected to the linkage plate 12, and a movable rod 13 is connected to the bottom of the linkage plate 12. A water supply pipe 14 is connected to the inner side of the other end of the movable rod 13, and a nozzle 15 is provided at one end of the water supply pipe 14. The other end of the water supply pipe 14 is connected to a rotating seat 16. In this embodiment, the fish to be descaled is transported to the inside of the outer shell 1 through the inlet 2 on the side wall of the outer shell 1. As the fish is fed in, the angles of the first body 4 and the second body 5 on both sides can be adjusted to facilitate better clamping of the fish. When the spray angle of the nozzle 15 needs to be adjusted according to actual usage requirements, the transmission structure is used to rotate the transmission shaft 10 connected to its output end. The rotation of the transmission shaft 10 drives the rotating arm 11 to rotate as well. Since one end of the rotating arm 11 is slidably connected to the linkage plate 12, the movement of the rotating arm 11 drives the movement of the linkage plate 12. Under the action of the rotating arm 11, the linkage plate 12 moves longitudinally, and thus, with the longitudinal movement of the linkage plate 12… The movable rod 13 can be pulled to move the water supply pipe 14. At this time, one end of the water supply pipe 14 will rotate along the bottom side of the machine body through the rotating seat 16, thereby realizing the angle adjustment of the water supply pipe 14. This facilitates the subsequent better use of the movement of the water supply pipe 14 to adjust the position of the nozzle 15. The adjustment of the nozzle 15 can effectively remove scales from the surface of the fish. Since the transmission structure can realize the forward and reverse rotation of the transmission shaft 10 with the forward and reverse rotation of the motor during operation, the water supply pipe 14 will drive the nozzle 15 to reciprocate. High-pressure water circulates and impacts the fish scales through the nozzle 15, thereby better removing scales from the surface of the fish during the horizontal transport process.

[0021] It is worth noting that a slot is formed on the side wall of the rotating arm 11 near the linkage plate 12, and a protrusion is provided on one end of the linkage plate 12. This protrusion extends into the slot in the side wall of the rotating arm 11, thereby realizing a sliding connection between the linkage plate 12 and the rotating arm 11. In addition, a limiting end is provided at the end of the protrusion to prevent the protrusion from sliding out.

[0022] like Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the transmission structure of the present invention includes a first motor 7, a driving gear 8 and a driven gear 9. The first motor 7 is fixedly mounted on one side of the top of the first body 4, and the output end of the first motor 7 is connected to the driving gear 8. The driven gear 9 is meshed on one side of the driving gear 8, and the center of one side of the driven gear 9 is fixedly connected to the transmission shaft 10.

[0023] In this embodiment, as the first motor 7 operates, the first motor 7 will cause the drive gear 8 connected to its output end to rotate as well. The rotation of the drive gear 8 will then be used to realize the rotation of the driven gear 9 that meshes with it on one side. Since the driven gear 9 and the transmission shaft 10 are fixedly connected, the rotation of the driven gear 9 will realize the movement of the transmission shaft 10, which will facilitate the subsequent movement of the rotating arm 11 by the movement of the transmission shaft 10.

[0024] like Figure 5 and Figure 6 As shown, a second motor 17 is distributed on one side of the first motor 7, and the output end of the second motor 17 is connected to a rotating shaft 18. A transmission roller 19 is connected to the bottom of the rotating shaft 18, and a conveyor belt 20 is fitted onto the outer ring of the transmission roller 19. When the second motor 17 is powered on, the rotating shaft 18 connected to its output end also rotates. This rotation of the rotating shaft 18 drives the transmission roller 19 connected to its output end to rotate as well. The rotation of the transmission roller 19, combined with the movement of the conveyor belt 20 fitted onto its outer surface, enables the transport and processing of the fish, facilitating subsequent descaling. The transmission roller 19 includes a driving roller and a driven roller. The driving roller is driven by the second motor 17, and the driven roller is rotatably connected to the machine body via a shaft.

[0025] like Figure 5 , Figure 6 and Figure 7 As shown, a third motor 21 is fixed to one side of the top of the bracket 3, and a rotating seat 22 is provided at the bottom of the third motor 21. A first pulley 23 is distributed on one side of the rotating seat 22. A support side plate 24 is welded to the side wall of the bracket 3, and a second pulley 25 is rotatably connected to the inner wall of the support side plate 24. A pull rope 26 is sleeved on the outer upper part of the rotating seat 22. A bending rod 27 is welded to one side of the bottom of the first body 4, and a tension spring 28 is connected to the outer bottom of the bending rod 27. It is worth noting that there are multiple bending rods 27, and the multiple bending rods 27 are respectively fixed to the side walls of the first body 4 and the second body 5. At the same time, the two ends of the tension spring 28 are respectively connected to the bending rods 27 welded to the side walls of the first body 4 and the second body 5.

[0026] In this embodiment, when it is necessary to adjust the tilt of the first body 4 and the second body 5 on both sides, the third motor 21 operates, causing the rotating seat 22 connected to its output end to rotate. Since a pull rope 26 is sleeved on the outer side of the rotating seat 22, and the pull rope 26 is connected to the side walls of the first body 4 and the second body 5 via the first pulley 23 and the second pulley 25 respectively, the rotation of the rotating seat 22 causes the two ends of the pull rope 26 to pull the first body 4 and the second body 5 respectively, thereby adjusting the angle between the two bodies. With the relative movement between the first body 4 and the second body 5, the body will pull the tension spring 28, causing it to deform and generate a reverse force, which facilitates the subsequent reset of the two bodies when the rotating seat 22 rotates in the opposite direction.

[0027] like Figure 4 and Figure 5 As shown, in this invention, a connecting plate 29 is rotatably connected to one end sidewall of the first body 4, and a linkage shaft 30 passes through the inner side of one end of the connecting plate 29. A toothed plate 31 is sleeved on the outer side of the bottom of the linkage shaft 30. A support plate is provided at the end of the connecting plate 29 away from the linkage shaft 30. The support plate is fixed to the vertical rod. Second bearings are fixedly connected to both the upper and lower ends of the vertical rod. The inner ring of the second bearing is fixed to the vertical rod, and the outer ring of the second bearing is fixedly connected to the first body 4 or the second body 5.

[0028] In this embodiment, two connecting plates 29 are provided. When the first body 4 and the second body 5 are adjusted at an angle under the action of the pull rope 26, the body will drive the connecting plates 29 to move relative to each other. At this time, the connecting plates 29 symmetrically arranged on both sides will move relative to each other, and their other ends will drive the linkage shaft 30 to move accordingly. With the movement of the linkage shafts 30 on both sides, the toothed plates 31 will also move. Since there are two toothed plates 31 and the two toothed plates 31 are meshed, the meshing movement of the two toothed plates 31 can be used to achieve the purpose of auxiliary limiting.

[0029] like Figure 3 , Figure 4 and Figure 6 As shown, in this invention, the outer ring surface of the driving gear 8 has multiple teeth arranged at equal intervals along the center point, and the driving gear 8 is meshed with the driven gear 9 through the teeth. In this embodiment, since the outer ring surfaces of both the driving gear 8 and the driven gear 9 are arranged in a ring array with multiple teeth, and the driving gear 8 and the driven gear 9 are connected by meshing teeth, the rotation of the driving gear 8 can easily enable the subsequent rotation of the driven gear 9.

[0030] like Figure 7As shown, in this invention, the first pulley 23 is rotatably connected to the bracket 3 through a bearing seat, and the first pulleys 23 on both sides are obliquely symmetrically distributed along the vertical center line of the bracket 3. In this embodiment, since there are two first pulleys 23, and the two first pulleys 23 are rotatably connected to the bracket 3 respectively, and the outer side of the first pulley 23 is connected to the pull rope 26, when the pull rope 26 is pulled, the two first pulleys 23 can be used to assist the movement, and the direction of the force can be changed by using the arrangement of multiple pulleys.

[0031] like Figure 3 and Figure 5 As shown, in this invention, one end of the rotating shaft 18 is connected to the output end of the second motor 17, while the other end of the rotating shaft 18 is detachably connected to the transmission roller 19, and the rotating shafts 18 are arranged in parallel. There are two transmission rollers 19, which are arranged in parallel, and the two transmission rollers 19 are respectively connected to the output end of the second motor 17 and the bottom of one end of the second body 5 via the rotating shaft 18.

[0032] In this embodiment, since there are two transmission rollers 19, and the two transmission rollers 19 are respectively connected to the second motor 17 and the machine body, the transmission roller 19 connected to the output end of the second motor 17 can rotate as the second motor 17 operates. When the transmission roller 19 rotates, the conveyor belt 20 will move, thereby realizing the synchronous movement of the transmission roller 19 on the other side of the conveyor belt 20. The transmission roller 19 on the other side of the conveyor belt 20 is rotatably connected to the first machine body 4 or the second machine body 5 through a shaft.

[0033] The usage and working principle of this adaptive clamping hydraulic fish descaling device are as follows: In use, the fish to be descaled is transported to the inside of the outer shell 1 through the feed port 2 opened on the side wall of the outer shell 1. Then, as the fish is input, the third motor 21 works to make the rotating seat 22 connected to its output end rotate. Since the outer side of the rotating seat 22 is fitted with a pull rope 26, and the pull rope 26 is connected to the side walls of the first machine body 4 and the second machine body 5 through the first pulley 23 and the second pulley 25 respectively, the rotation of the rotating seat 22 can make the two ends of the pull rope 26 pull the first machine body 4 and the second machine body 5 respectively, thereby realizing the adjustment of the angle between the two machines.

[0034] In the initial stage of fish transport, due to the large size of the fish head, the tension spring 28 and the pull rope 26 work together to drive the first body 4 and the second body 5 to form an inclined clamping opening facing the fish head, thus effectively clamping the fish head. As the fish continues to advance, the tail gradually enters the clamping area, and its cross-sectional size decreases. At this time, the tension on the pull rope 26 continues to increase. Under the combined action of the elastic compensation of the tension spring 28 and the dynamic traction of the pull rope 26, the clamping opening of the first body 4 and the second body 5 can still adaptively maintain its orientation towards the front end of the fish, i.e., the original direction of the fish head, and stably clamp the tail part.

[0035] Throughout the conveying process, the tension applied by the pull rope 26 to the front ends of the first body 4 and the second body 5 continuously increases, ensuring that the clamping mechanism always provides clamping force that adapts to changes in the fish's body contour, effectively avoiding clamping failure due to the small size of the fish tail. Adaptive clamping significantly improves clamping stability, thereby ensuring the uniformity and thoroughness of the subsequent high-pressure water descaling process.

[0036] The tension of the pull rope 26 can be controlled by adjusting the duration of the forward or reverse rotation of the third motor 21. On the one hand, a program can be set based on experimental data to automatically adjust the running time of the third motor 21; on the other hand, the operator can also manually control the duration of the forward or reverse rotation of the third motor 21 according to the actual working conditions (generally requiring the outer casing 1 to be opened), dynamically adjusting the tension of the pull rope 26. With the elastic feedback of the tension spring 28, this control strategy can achieve real-time adaptive clamping of the fish body, working in conjunction with the multi-angle high-pressure water impact of the nozzle 15 to ultimately achieve an efficient and stable descaling effect.

[0037] like Figure 8 , Figure 9 and Figure 10The image shows the seventh generation of the fish descaling device. The relative movement between the two bodies facilitates the clamping and handling of the fish. When the spray angle of the nozzle 15 needs to be adjusted according to actual usage requirements, the first motor 7 rotates the drive gear 8 connected to its output end. This rotation of the drive gear 8, in turn, causes the driven gear 9, which meshes with it on one side, to rotate. Since the driven gear 9 is fixedly connected to the transmission shaft 10 and they are perpendicularly arranged, the rotation of the driven gear 9 moves the transmission shaft 10. This rotation of the transmission shaft 10 then drives the rotating arm 11 to rotate as well. One end of the rotating arm 11 is slidably connected to the linkage plate 12. Therefore, the movement of the rotating arm 11 drives the movement of the linkage plate 12, causing it to move longitudinally. This longitudinal movement of the linkage plate 12 pulls the movable rod 13, which in turn pulls the water pipe 14. One end of the water pipe 14 then rotates along one side of the bottom of the machine body via the rotating seat 16. During the fish transport process, the water pipe 14 is driven by the mechanism to swing up and down, causing the nozzle 15 to perform a synchronous periodic reciprocating motion. High-pressure water flows through the nozzle 15 and continuously impacts the surface of the fish at a dynamic angle, forming a multi-directional, variable-angle spray effect. Compared with the traditional fixed-point high-pressure water descaling process, this method can effectively cover the corners and recessed areas of the fish's outline, significantly improving the comprehensiveness and thoroughness of descaling, thus better removing fish scales from the surface of the fish.

[0038] The above embodiments are merely illustrative of the technical solutions of the present invention and are not intended to limit it. Anyone skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.

Step 2: When the spray angle of the nozzle (15) needs to be adjusted according to the actual usage requirements, the first motor (7) will cause the drive gear (8) connected to its output end to rotate as well. Then, the rotation of the drive gear (8) will realize the rotation of the driven gear (9) meshing with it on one side. Since the driven gear (9) and the transmission shaft (10) are fixedly connected, the rotation of the driven gear (9) will realize the movement of the transmission shaft (10). At this time, the rotation of the transmission shaft (10) will drive the rotating arm (11) to rotate as well. Step 3: Since one end of the rotating arm (11) is slidably connected to the linkage plate (12), the movement of the rotating arm (11) can drive the movement of the linkage plate (12). At this time, the linkage plate (12) will move longitudinally under the action of the rotating arm (11), and the longitudinal movement of the linkage plate (12) can pull the movable rod (13), and then the movement of the movable rod (13) can be used to pull the water pipe (14). Step 4: At this time, one end of the water supply pipe (14) will rotate along the bottom side of the machine body through the rotating seat (16) to adjust the angle of the water supply pipe (14), so as to make it easier to use the movement of the water supply pipe (14) to adjust the position of the nozzle (15) and effectively remove scales from the surface of the fish by adjusting the nozzle (15), while improving the flexibility of the whole device.
