Description

Technical Field

[0001] This utility model relates to the technical field of aquatic product processing equipment, and in particular to a three-section conveyor type directional descaling machine for freshwater fish. Background Technology

[0002] Fish scales are one of the important factors affecting the taste and quality of processed fish. In order to improve the efficiency of fish scale removal and reduce labor intensity, a scaler is needed to remove fish scales.

[0003] Currently, fish scaling is still mainly done manually, with workers using knives to remove the scales. However, this method is inefficient and cannot meet the needs of large-scale production.

[0004] In addition, although machine descaling can remove fish scales relatively efficiently, it has the disadvantage of poor descaling effect, especially since there are often a lot of scales on the back and belly of the fish. This means that after the scaler removes the scales, workers still need to manually process the scales on the back or belly of the fish, resulting in a poor user experience. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a three-section conveyor type freshwater fish directional descaling machine, which has good descaling efficiency, flexible use, wide adaptability, and can be adjusted according to fish of different sizes. Compared with the prior art, it can reduce the space occupied by the descaling machine and the equipment is easy to debug.

[0006] To achieve the above objectives, this utility model provides a three-section conveying freshwater fish directional descaling machine, comprising: a frame; a support plate placed inside the top of the frame and used to support the fish body; a first conveying mechanism, a second conveying mechanism, and a third conveying mechanism with identical structures arranged sequentially on the support plate along the conveying direction of the fish body, each conveying mechanism including two transmission belts with adjustable spacing for clamping the fish body, the two transmission belts forming a fish delivery channel; a roller descaling mechanism located between the first and second conveying mechanisms, including a descaling motor and two sets of descaling mechanisms, the two sets of descaling mechanisms being distributed on opposite sides of the fish delivery channel along the height direction of the frame, each descaling mechanism including a descaling roller and descaling roller brushes evenly distributed on the peripheral wall of the descaling roller; and a high-pressure descaling and cleaning mechanism located between the second and third conveying mechanisms, including two sets of spraying mechanisms, the two sets of spraying mechanisms being perpendicular to the conveying direction of the transmission belts, and the two sets of spraying mechanisms being located on opposite sides of the fish delivery channel; each set of spraying mechanisms including a high-pressure cleaning linkage and a nozzle mounted on the high-pressure cleaning linkage.

[0007] Preferably, each conveying mechanism includes a first roller shaft, a second roller shaft parallel to the first roller shaft, and a transmission belt sleeved between the first roller shaft and the second roller shaft; the top end of the first roller shaft is provided with a first roller gear coaxially arranged with the first roller shaft, the first roller gear meshes with a synchronous pulley, the synchronous pulley is coaxially arranged with the front shaft of the adjusting plate, the front shaft of the adjusting plate and the opposing roller shaft are connected by a belt, the opposing roller shaft is connected to the conveying motor by a belt, and another transmission belt is sleeved between the two opposing roller shafts.

[0008] Furthermore, the skeleton in the transmission belt between the two opposing rollers is fixedly connected to the frame by bolts, and the transmission belt on the other side is slidably connected to the slide rod by a movable slider to form a sliding component of the conveying mechanism. The slide rod is fixed to the frame by a slide rod support.

[0009] Preferably, one end of the adjusting plate is rotatably connected to the top of the opposing roller shaft. The distance between the two opposing transmission belts is adjusted by adjusting the position of the arc-shaped groove of the adjusting plate, which drives the front shaft of the adjusting plate and the belt to rotate outward together, thereby driving the synchronous pulley to rotate outward. The fixed frame between the first roller shaft and the second roller shaft is connected to the movable slider of the conveying mechanism slider component. By moving the movable slider on the slide rod of the conveying mechanism slider component, the movement of the synchronous pulley changes the left and right movement of the first roller gear meshing with it, thereby achieving the purpose of adjusting the first roller gear and thus changing the distance between the two transmission belts.

[0010] Furthermore, the descaling roller and the descaling motor are coaxially arranged, and one side of the descaling motor is fixed to the top cover of the frame through a descaling motor support. The other side of the descaling motor support is penetrated by a guide rod and moves along the guide rod. The guide rod is fixed to the upper end of the frame through a guide rod support. A spring is provided on the outer periphery of the guide rod between the descaling motor support and the guide rod support.

[0011] Furthermore, the high-pressure cleaning linkage extends along the height of the frame and is fixed to both sides of the fish delivery channel by bolts; the nozzle is connected to the water pump so that the water pump can pump high-pressure water flow to the nozzle.

[0012] Preferably, the nozzle's spray opening is oriented towards the extension line of the fish delivery channel, and the nozzle can rotate relative to the high-pressure cleaning linkage to adjust the nozzle's spray angle.

[0013] Furthermore, the transmission belt is a double-sided toothed transmission belt.

[0014] Based on the above, compared with the prior art, the three-section conveyor type freshwater fish directional descaling machine of this utility model has at least the following advantages:

[0015] Beneficial effects:

[0016] 1. This utility model features a novel structure, including a frame and three independently configured conveying mechanisms mounted on a support plate, forming three independent fish feeding channels. The roller descaling mechanism comprises a descaling motor and descaling rollers. Two sets of roller descaling mechanisms are distributed along the height of the frame on opposite sides of the fish feeding channels. The descaling motor is mounted above the support plate. The descaling rollers rotate in opposite directions, towards the outside of the frame. This rotation method allows the fish on the support plate to move forward while simultaneously increasing the relative resistance to the scales, resulting in better descaling and preventing the fish from being squeezed under the descaling rollers. Composed of two descaling mechanisms, adjustable for different fish sizes, this design reduces the space occupied by the descaling machine compared to existing technologies.

[0017] 2. By setting up a high-pressure descaling and cleaning mechanism, the problem of cleaning is solved at the same time as descaling, which greatly reduces the area occupied by the descaling machine and makes the equipment easy to debug.

[0018] 3. By controlling three independent conveyor sections with three independent motors, it is easier to adjust the optimal conveyor speed of each section, thereby maximizing descaling efficiency and optimizing the effect.

[0019] 4. The spacing of the conveying mechanism can be adjusted to suit fish of different sizes, making it flexible and adaptable. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] See below. Figures 1-6 This invention provides a detailed description of the three-section conveyor type directional descaling machine for freshwater fish.

[0030] The three-section conveying freshwater fish directional descaling machine of this utility model includes a frame 1 and a support plate 2 placed inside the top of the frame 1 to support the fish body. A first conveying mechanism 3, a roller descaling mechanism 4, a second conveying mechanism 5, a high-pressure descaling and cleaning mechanism 6, and a third conveying mechanism 7 are sequentially arranged on the support plate 2 along the conveying direction of the fish body. The drive devices of all mechanisms are installed on the frame 1. The purpose is to avoid the motor from working in a humid environment, thereby reducing safety hazards.

[0031] Combination Figure 1-2The frame 1 contains a support plate 2. The three conveyor sections are numbered 1-3 according to the fish transport direction, and all three sections have identical structures. Each of the three independent conveyor sections is powered by a separate motor, allowing for different transport speeds. These three sections form a fish delivery channel, which is divided into a first, second, and third conveyor section based on its distance from the inlet. Taking the first conveyor section 3 as an example, each section includes a first roller 31, a second roller 35, and a drive belt 37. The first and second rollers 31 are parallel to each other, and there is a gap between the first and second rollers 31 and the support plate 2. A drive belt 37 is fitted between the first and second rollers 31 and 35 to achieve linkage between them.

[0032] Preferably, a first roller gear 38 is provided at the top of the first roller shaft 31. The first roller gear 38 is coaxially arranged with the first roller shaft 31, and the first roller gear 38 meshes with the synchronous pulley 391 of the spacing adjustment mechanism. The synchronous pulley 391 is coaxially arranged with the front shaft 392 of the adjusting plate. The front shaft 392 of the adjusting plate and the opposing roller shaft 33 are connected by a belt 394 to achieve the purpose of transmission. The opposing roller shaft 33 is connected to the conveying motor 34 by a belt. Another transmission belt 37 is sleeved between the two opposing roller shafts 33 to achieve synchronous operation of the two sets of transmission belts. In addition, each conveying mechanism can clamp the fish body through its two transmission belts 37 and transport the fish from the inlet end of the fish delivery channel 32 to the outlet end of the fish delivery channel 32 through the transmission of the transmission belts 37. The two transmission belts 37 constitute the fish delivery channel 32.

[0033] Furthermore, the transmission belt 37 is preferably a double-sided toothed transmission belt, which not only ensures the reliability of the transmission between the transmission belt 37 and the first roller shaft 31 and the second roller shaft 35, but also increases the friction between the transmission belt and the fish body, so that the cooperation of the two transmission belts 37 can reliably clamp the fish and reliably transport it.

[0034] The skeleton in the transmission belt 37 (sleeved between two opposing roller shafts 33) on one side of the conveying mechanism is fixedly connected to the frame 1 by bolts, and the two opposing roller shafts 33 are rotatably installed at both ends of the skeleton; the fixed frame in the transmission belt 37 on the other side is slidably connected to the slide rod by a movable slider to form the sliding component 36 of the conveying mechanism, and the slide rod is fixed to the frame 1 by a slide rod support.

[0035] Specifically, one end of the adjusting plate 393 is rotatably connected to the top of the opposing roller shaft 33. The spacing adjustment function of the two opposing transmission belts 37 is mainly achieved by adjusting the position of the arc-shaped groove of the adjusting plate 393, which drives the front shaft 392 of the adjusting plate and the belt 394 to rotate outward together, thereby driving the synchronous pulley 391 to rotate outward. The fixed frame between the first roller shaft 31 and the second roller shaft 35 (the first roller shaft 31 and the second roller shaft 35 are rotatably installed at both ends of the fixed frame) is connected to the movable slider of the conveying mechanism slider 36. By moving the movable slider on the slide bar of the conveying mechanism slider 36, the movement of the synchronous pulley 391 changes the left and right movement of the meshing first roller gear 38, thereby achieving the purpose of adjusting the first roller gear 38, and thus changing the distance between the two transmission belts 37 to meet the needs of processing fish of different batch sizes.

[0036] Combination Figure 3 The roller descaling mechanism 4 is located between the first conveying mechanism 3 and the second conveying mechanism 5. It includes a descaling motor 43 and two sets of descaling mechanisms. The two sets of descaling mechanisms are distributed on opposite sides of the fish feeding channel along the height direction of the frame 1. The descaling mechanisms are installed on the upper end of the support plate 2. Each descaling mechanism includes a descaling roller 44 and descaling roller brushes 45 evenly distributed on the peripheral wall of the descaling roller 44. The axial direction of the descaling roller 44 is perpendicular to the fish feeding direction of the fish feeding channel. The roller descaling mechanism 4 uses brushes as tools to scrape the scales off the back or belly of the fish. The descaling rollers 44 are arranged on both sides of the fish feeding channel 32. The two sets of descaling rollers 44 rotate in opposite directions, rotating outward from the frame 1. This rotation method allows the fish on the support plate 2 to move forward while the relative resistance to the scales is greater, resulting in better descaling and preventing the fish from being squeezed under the descaling roller brushes 45. Meanwhile, the descaling roller 44 and the descaling motor 43 are coaxially arranged. The descaling motor 43 drives the descaling roller 44 to rotate. One side of the descaling motor 43 is fixed to the top cover of the frame 1 through the descaling motor support. The other side of the descaling motor support is penetrated by the smooth rod 41 and moves along the smooth rod 41. The smooth rod 41 is fixed to the upper end of the frame 1 through the smooth rod support. A spring 42 is provided on the outer periphery of the smooth rod 41 between the descaling motor support and the smooth rod support on the other side, so as to allow fish of a certain size range to pass through during the descaling process, which is convenient for removing the scales of fish of different sizes.

[0037] refer to Figure 4 The descaling roller brush 45 is bolted and detachable. The hardness and material of the descaling roller brush 45 can be adjusted to suit different fish species. Different materials and sizes of descaling brushes can be selected based on the type and size of the fish to achieve targeted descaling. The descaling roller brush 45 can also be a silicone brush evenly distributed on the peripheral wall of the descaling roller 44.

[0038] refer to Figure 5The high-pressure descaling and cleaning mechanism 6 is located between the second conveying mechanism 5 and the third conveying mechanism 7. The high-pressure descaling and cleaning mechanism 6 includes two sets of spraying mechanisms, which are perpendicular to the transport direction of the transmission belt 37 and located on both sides of the fish delivery channel 32. Each spraying mechanism includes a high-pressure cleaning connecting rod 61 and nozzles 62 mounted on the high-pressure cleaning connecting rod 61. The high-pressure cleaning connecting rod 61 extends along the height of the frame 1 and is fixed to both sides of the fish delivery channel by bolts. Several adjustable nozzles 62 are fixed to the outer wall of the high-pressure cleaning connecting rod 61 by bolts, and the nozzles 62 can be rotated to adjust their direction. The nozzles 62 are connected to a water pump, enabling the water pump to pump high-pressure water flow to the nozzles 62. The water pump can be a pump integrated into the descaling machine itself or an external water pump additionally installed for the descaling machine.

[0039] Combination Figure 6 The nozzle 62 is positioned with its spray outlet facing the extension line of the fish delivery channel 32, and the nozzle 62 can rotate relative to the high-pressure cleaning linkage 61 to adjust the spray angle of the nozzle 62, so that the high-pressure water jet sprayed from the nozzle 62 can better scrape off the fish scales. The high-pressure descaling and cleaning mechanism 6 can perform a second descaling while cleaning the inside of the machine. The removed fish scales and debris will fall onto the filter screen for unified collection, realizing a self-cleaning function.

[0040] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any transformations or substitutions that can be understood by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of this utility model.
