Description
Technical Field
[0001] This utility model relates to the field of fish-killing platform technology, and in particular to a fish-killing combination platform. Background Technology
[0002] Fish are a type of aquatic vertebrate. A fish-killing station is a specialized piece of equipment designed specifically for the slaughtering and cleaning of fish. It is commonly used in seafood markets, restaurant kitchens, and food processing plants to improve fish processing efficiency and hygiene. A combination fish-killing station is a multi-functional integrated device designed for the slaughtering, cleaning, and processing of fish. It improves operational efficiency through modular combination and is commonly found in seafood markets, restaurant kitchens, and food processing plants. Its core feature is that it integrates multiple processing functions into one unit, unlike a single-function fish-killing station, and emphasizes the efficiency and convenience brought by the "combination".
[0003] A search revealed Chinese Patent Publication No. CN112056370A, which discloses a multifunctional fish-killing platform, including a fish-killing platform support frame (3) with a faucet (1), a water tank (2), and a fish-killing workbench. The platform is characterized by further including a fish-placement platform (4) mounted on the support frame (3) and an anti-slip mat (5) mounted on the workbench. The fish-placement platform (4) has several grooves (6) for placing fish and markings (7) corresponding to each groove (6). A collection hole (8) for collecting debris during the fish-killing process is provided in the center of the anti-slip mat (5). This invention is versatile and easy to implement, suitable for high-frequency slaughtering scenarios. It is not only easy to operate but also effectively solves the technical problems existing in the prior art. However, the faucet in the existing device has a fixed position and cannot be flexibly adjusted according to needs. This results in water flow not reaching the corners of the fish-killing platform or cleaning the gaps in the fish, requiring manual movement of the fish or tools, increasing operational complexity and time costs. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a fish-killing combination table, which aims to improve the problem that the faucet position in the existing device is fixed and cannot be flexibly adjusted according to needs, requiring manual movement of the fish or tools, thus increasing the complexity of operation and time cost.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fish-killing combination platform, comprising a frame, an elongated block fixedly connected inside the frame, a moving mechanism installed on the top rear side of the elongated block for moving, a pushing mechanism provided on the right side of the front end of the inner wall of the elongated block for cleaning impurities; the moving mechanism includes a moving block installed on the inner rear side of the elongated block, a faucet installed on the top of the moving block, and a driving component installed on the outer rear side of the elongated block.
[0006] The above technical solution involves using a driving component to move the movable block and the top faucet, thereby achieving the effect of meeting different usage needs.
[0007] As a further description of the above technical solution:
[0008] The drive assembly includes a motor, which is mounted on the rear side of the outer wall of the frame. A connecting rod is fixedly connected to the output end of the motor, and a gear is fixedly connected to the top end of the connecting rod. A rack is slidably connected to the rear side of the inner wall of the elongated block, and the rack meshes with the gear. Limiting plates are fixedly connected to the left and right ends of the outer wall of the rack. A water-receiving hose is connected to the bottom end of the faucet.
[0009] Through the above technical solution: when the motor is started, its output shaft drives the connecting rod to rotate, converting the motor's circular motion into transmission power.
[0010] The gear at the top of the connecting rod rotates synchronously with the shaft. Through the meshing of the gear teeth and the rack, the rotational motion is converted into the linear sliding of the rack. Since the rack is slidably connected to the rear side of the inner wall of the elongated block through the guide rail pair, the rack can only move linearly along the length of the elongated block. The limiting plates at both ends of the rack cooperate with the inner wall of the elongated block to limit the sliding stroke of the rack and prevent it from derailing. At the same time, the side of the limiting plate contacts the guide rail, further enhancing the stability of the motion and ensuring that the gear and rack always maintain correct meshing. The moving block is fixedly connected to the rack. When the rack slides, the moving block synchronously drives the faucet at the top to move laterally along the elongated block. The water hose adopts a flexible design to maintain water supply during the movement of the faucet, and at the same time, it adapts to position changes through its own bending deformation.
[0011] As a further description of the above technical solution:
[0012] The pushing mechanism includes a debris trough, which is located on the right side of the front end of the inner wall of the elongated block. Elongated sliding grooves are formed on both the front and rear sides of the inner wall of the debris trough. A push plate is slidably connected inside the elongated sliding groove. A return spring is fixedly connected to the left side of the inner wall of the elongated block. The other end of the outer wall of the return spring is fixedly connected to the left side of the outer wall of the push plate. A square plate is fixedly connected to the right side of the outer wall of the elongated block. A fixed short column is rotatably connected inside the square plate. A pull rope is fixedly connected to the outer wall of the fixed short column. The other end of the outer wall of the pull rope is fixedly connected to the right side of the outer wall of the push plate. Multiple rolling short columns are equidistantly rotatably connected to the right side of the inner wall of the rear elongated sliding groove.
[0013] The above technical solution involves the following: During the fish-killing process, fish scales, viscera, and other debris are temporarily stored in a debris trough on the right side of the inner wall of the elongated block. At this time, the push plate, under the action of the return spring, is positioned on the left side of the debris trough, providing space for the debris. When it is necessary to clean the debris from the trough, the operator rotates the fixed short column inside the square plate. After the fixed short column rotates, the pull rope wrapped around its outer wall begins to tighten. The tension generated by the tightening pull rope causes the push plate connected to it to slide within the elongated chute. The rolling short columns, equidistantly connected to the right side of the inner wall of the rear elongated chute, effectively reduce the pushing... The friction of the moving plate makes its sliding smoother. Under the action of the pulling force, the push plate moves from the left side to the right side of the debris trough, pushing fish scales, internal organs and other debris in the debris trough to the rotating door for cleaning. After cleaning, the operator stops rotating the fixed short column. At this time, the return spring plays its role. The return spring was compressed because the push plate moved to the right. It has the elastic force to restore its deformation. This elastic force pushes the push plate to slide to the left along the long slide, returning to the initial position, preparing for the next debris cleaning. There is no need to manually remove the debris bit by bit, which greatly shortens the cleaning time after fish killing and improves the efficiency and convenience of the fish killing combination table.
[0014] As a further description of the above technical solution:
[0015] A cleaning groove is provided on the top left side of the elongated block, and a fish scale and viscera treatment groove is provided on the top right side of the elongated block.
[0016] The above technical solution involves a cleaning tank for cleaning fish and a fish scale and viscera treatment tank for secondary cleaning of the slaughtered fish.
[0017] As a further description of the above technical solution:
[0018] A fish-killing cutting board is fixedly connected to the middle of the top wall of the elongated block, and a hinge is fixedly connected to the right side of the outer wall of the elongated block.
[0019] The above technical solution enables fish-killing cutting boards to facilitate the slaughtering of fish by staff.
[0020] As a further description of the above technical solution:
[0021] A rotating door is rotatably connected to the other side of the outer wall of the hinge, and a buckle is fixedly connected to the right side of the outer wall of the rotating door.
[0022] Through the above technical solution, the rotating door on the other side of the hinge's outer wall can cover the storage compartment when not in use.
[0023] As a further description of the above technical solution:
[0024] A hollow shell is fixedly connected to the rear side of the outer wall of the elongated block, and a fastening ring is fixedly connected to the right side of the outer wall of the elongated block. The fastening ring engages with the buckle.
[0025] Through the above technical solution, the hollow shell can protect the motor, and the interlocking of the clasp and buckle can strengthen the sealing of the revolving door.
[0026] As a further description of the above technical solution:
[0027] Adjusting bolts are installed at the four corners of the bottom of the frame, and anti-slip pads are threaded onto the outer wall of the adjusting bolts.
[0028] The above technical solution, namely the anti-slip pads connected to the outer thread of the adjusting bolt, can prevent the fish-killing platform from shifting during use.
[0029] This utility model has the following beneficial effects:
[0030] 1. In this utility model, by starting the motor, the connecting rod is driven to rotate, which drives the gear to rotate. The gear meshes with the rack, causing the rack to slide in the elongated block, thereby moving the faucet. The limiting plate ensures that the rack moves stably, and the moving block moves accordingly, so that the faucet can be accurately positioned above the cleaning tank, the fish-killing cutting board, or the fish scale and internal organ processing tank. After operating on the fish-killing cutting board, the faucet is moved to rinse, meeting different cleaning needs.
[0031] 2. In this utility model, the push plate, under the action of the return spring, leaves space for storing debris. During cleaning, the operator rotates the fixed short column and pulls the rope to drive the push plate to slide, pushing the debris to the rotating door. After cleaning, the return spring returns the push plate to the initial position, ready for the next cleaning, reducing cleaning time and improving the efficiency and convenience of the fish-killing combination station.

Detailed Implementation
[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0043] Reference Figure 4 , Figure 5 and Figure 7This utility model provides an embodiment of a fish-killing assembly, comprising a frame 1, an elongated block 6 fixedly connected inside the frame 1, a moving mechanism 2 installed on the top rear side of the elongated block 6 for moving, and a pushing mechanism 3 provided on the right side of the front end of the inner wall of the elongated block 6 for cleaning impurities; the moving mechanism 2 includes a moving block 201 installed on the inner rear side of the elongated block 6, a faucet 202 installed on the top of the moving block 201, and a driving assembly 203 installed on the outer rear side of the elongated block 6, the driving assembly 203 including a motor 2031 installed on the outer side of the frame 1. On the rear side of the wall, a connecting rod 2032 is fixedly connected to the output end of the motor 2031, and a gear 2033 is fixedly connected to the top end of the connecting rod 2032. A rack 2036 is slidably connected to the rear side of the inner wall of the elongated block 6. The rack 2036 meshes with the gear 2033. Limiting plates 2035 are fixedly connected to the left and right ends of the outer wall of the rack 2036. A water receiving hose 2034 is connected to the bottom end of the faucet 202. A cleaning tank 4 is opened on the top left side of the elongated block 6, and a fish scale and viscera treatment tank 5 is opened on the top right side of the elongated block 6. The cleaning tank 4 is used to clean fish, and the fish scale and viscera treatment tank 5 is used to perform secondary cleaning on the slaughtered fish.
[0044] Specifically, when the position of the faucet 202 needs to be adjusted, the motor 2031 is started, and its output end drives the connecting rod 2032 to rotate, which in turn drives the gear 2033 to rotate. The rack 2036, which meshes with the gear 2033, slides on the rear side of the inner wall of the elongated block 6. Due to the rotation of the gear 2033, the rack 2036 moves along the interior of the elongated block 6. The limiting plates 2035 at the left and right ends of the outer wall of the rack 2036 ensure its stable movement. At the same time, the moving block 201 connected to the rack 2036 moves accordingly, driving the faucet 202 at the top. Sliding horizontally along the elongated block 6, it can be precisely adjusted to be above the cleaning tank 4, the fish-killing cutting board 7, or the fish scale and viscera treatment tank 5. When killing fish on the fish-killing cutting board 7, and rinsing is required, the water faucet 202 is moved to use water flow to clean the fish, cutting board, and work area, thus meeting different cleaning needs. The cleaning tank 4 is located on the top left side of the elongated block 6, and the fish scale and viscera treatment tank 5 is located on the top right side of the elongated block 6. The cleaning tank 4 is used to clean fish, and the fish scale and viscera treatment tank 5 is used to perform a secondary cleaning of the fish after slaughter.
[0045] Reference Figure 2 , Figure 6 and Figure 8The pushing mechanism 3 includes a debris trough 301, which is located on the right side of the front end of the inner wall of the elongated block 6. Elongated sliding grooves 302 are provided on both the front and rear sides of the inner wall of the debris trough 301. A push plate 306 is slidably connected inside the elongated sliding groove 302. A return spring 307 is fixedly connected to the left side of the inner wall of the elongated block 6. The other end of the outer wall of the return spring 307 is fixedly connected to the left side of the outer wall of the push plate 306. A square plate 304 is fixedly connected to the right side of the outer wall of the elongated block 6. A fixed short column 305 is rotatably connected inside the square plate 304. A pull rope is fixedly connected to the outer wall of the fixed short column 305. 303, the other end of the outer wall of the pull rope 303 is fixedly connected to the right side of the outer wall of the push plate 306. Multiple rolling short columns 308 are equidistantly rotatably connected to the right side of the inner wall of the rear elongated slide 302. A fish-killing cutting board 7 is fixedly connected to the middle of the top wall of the elongated block 6. A hinge 8 is fixedly connected to the right side of the outer wall of the elongated block 6. The fish-killing cutting board 7 facilitates the workers to kill fish. A rotating door 10 is rotatably connected to the other side of the outer wall of the hinge 8. A buckle 9 is fixedly connected to the right side of the outer wall of the rotating door 10. The rotating door 10 on the other side of the outer wall of the hinge 8 can cover the debris trough 301 when not in use.
[0046] Specifically, during the fish-killing process, fish scales, entrails, and other debris are temporarily stored in the debris trough 301 on the right side of the inner wall of the elongated block 6. At this time, the push plate 306, under the action of the return spring 307, is positioned to the left of the debris trough 301, providing space for the debris. When it is necessary to clean the debris in the debris trough 301, the operator rotates the fixed short column 305 inside the square plate 304. After the fixed short column 305 rotates, the pull rope 303 wrapped around its outer wall begins to tighten. The tension generated by the tightening of the pull rope 303 causes the push plate 306 connected to it to slide within the elongated slide groove 302. The rolling short columns 308, equidistantly connected to the right side of the inner wall of the rear elongated slide groove 302, effectively reduce the friction when the push plate 306 moves, making its sliding smoother. Under the action of the tension, the push plate 306 moves from the left side to the right side of the debris trough 301, clearing the debris trough. After the fish scales, entrails, and other debris in 301 are pushed out to the rotating door 10 for cleaning, the operator stops rotating the fixed short column 305. At this time, the return spring 307 plays its role. The return spring 307 is compressed because the push plate 306 was moved to the right before, and has the elastic force to restore its deformation. This elastic force pushes the push plate 306 to slide to the left along the elongated slide 302 and return to the initial position, preparing for the next cleaning of debris. There is no need to manually remove the debris bit by bit, which greatly shortens the cleaning time after the fish killing operation and improves the efficiency and convenience of the fish killing combination table. The outer wall of the elongated block 6 is fixedly connected to the right side of the outer wall of the fish killing board 7, which makes it easy for the staff to kill fish. The other side of the outer wall of the hinge 8 is rotatably connected to the rotating door 10. The outer wall of the rotating door 10 is fixedly connected to the right side of the outer wall of the rotating door 10. The rotating door 10 on the other side of the outer wall of the hinge 8 can cover the debris tray 301 when not in use.
[0047] Reference Figure 1 , Figure 3 and Figure 4 A hollow shell 14 is fixedly connected to the rear side of the outer wall of the elongated block 6, and a fastening ring 11 is fixedly connected to the right side of the outer wall of the elongated block 6. The hollow shell 14 can protect the motor 2031. The fastening ring 11 and the fastening buckle 9 can strengthen the sealing of the rotating door 10. The fastening ring 11 and the fastening buckle 9 are engaged. Adjusting bolts 12 are installed at the four corners of the bottom of the frame 1. The outer wall of the adjusting bolt 12 is threaded with anti-slip pads 13. The anti-slip pads 13 threaded on the outer wall of the adjusting bolt 12 can prevent the fish killing platform from shifting during use.
[0048] Specifically, a hollow shell 14 is fixedly connected to the rear side of the outer wall of the elongated block 6, and a fastening ring 11 is fixedly connected to the right side of the outer wall of the elongated block 6. The hollow shell 14 can protect the motor 2031. The fastening ring 11 and the fastening buckle 9 can reinforce the sealing of the rotating door 10. The fastening ring 11 and the fastening buckle 9 are engaged. Adjusting bolts 12 are installed at the four corners of the bottom of the frame 1. The outer wall of the adjusting bolt 12 is threaded with anti-slip pads 13. The anti-slip pads 13 threaded on the outer wall of the adjusting bolt 12 can prevent the fish killing platform from shifting during use.
[0049] Working principle: When the position of the faucet 202 needs to be adjusted, the motor 2031 is started, and its output end drives the connecting rod 2032 to rotate, which in turn drives the gear 2033 to rotate. The rack 2036 meshing with the gear 2033 slides on the rear side of the inner wall of the elongated block 6. Due to the rotation of the gear 2033, the rack 2036 will move along the inside of the elongated block 6. The limiting pieces 2035 on the left and right ends of the outer wall of the rack 2036 ensure its stable movement. At the same time, the moving block 201 connected to the rack 2036 moves accordingly, causing the faucet 202 at the top to slide laterally along the elongated block 6. It can be precisely adjusted to the top of the cleaning tank 4, the fish-killing cutting board 7, or the fish scale and internal organ treatment tank 5. Fish-killing operations are performed on the fish-killing cutting board 7. When rinsing is required, the faucet 202 is moved to use the water flow to clean the fish, the cutting board, and the work area, thereby meeting different cleaning needs.
[0050] During the fish-killing process, fish scales, entrails, and other debris are temporarily stored in the debris trough 301 on the right side of the inner wall of the elongated block 6. At this time, the push plate 306, under the action of the return spring 307, is positioned to the left of the debris trough 301, providing space for the debris. When it is necessary to clean the debris from the debris trough 301, the operator rotates the fixed short column 305 inside the square plate 304. After the fixed short column 305 rotates, the pull rope 303 wrapped around its outer wall begins to tighten. The tension generated by the tightening of the pull rope 303 causes the push plate 306 connected to it to slide within the elongated slide groove 302. The rolling short columns 308, equidistantly connected to the right side of the inner wall of the rear elongated slide groove 302, effectively reduce... The friction of the push plate 306 during movement makes its sliding smoother. Under the action of the pulling force, the push plate 306 moves from the left side to the right side of the debris trough 301, pushing fish scales, internal organs and other debris in the debris trough 301 to the rotating door 10 for cleaning. After cleaning, the operator stops rotating the fixed short column 305. At this time, the return spring 307 plays its role. The return spring 307 was compressed because the push plate 306 moved to the right before, and has the elastic force to restore its deformation. This elastic force pushes the push plate 306 to slide to the left along the long slide 302 and return to the initial position, preparing for the next debris cleaning. There is no need to manually remove the debris bit by bit, which greatly shortens the cleaning time after the fish killing operation and improves the efficiency and convenience of the fish killing combination table.
