Description

Technical Field

[0001] This utility model relates to the field of fish-killing machine technology, and in particular to a fish-killing machine. Background Technology

[0002] In the modern aquatic product processing industry, fish-killing machines are being used more and more widely. Traditional manual fish-killing methods are not only labor-intensive and time-consuming, but also require highly skilled operators, resulting in low efficiency and making it difficult to meet the needs of large-scale, high-efficiency fish processing. The emergence of fish-killing machines has greatly improved this situation, as they can quickly complete a series of operations such as head and tail removal and internal organ cleaning, significantly improving fish processing efficiency.

[0003] Current fish-killing machines require adjusting the position of the fish's head during the gutting process to effectively remove internal organs. However, existing fish-killing machines generally lack an effective automatic head-position adjustment mechanism, typically requiring manual adjustment. This process is tedious and time-consuming, especially when processing large quantities of fish, as frequent manual adjustments significantly reduce overall fish-killing efficiency.

[0004] A mechanical automatic fish-killing machine is disclosed in utility model application number CN201921072746.8, which includes a storage tray, a fish body sensor, a limit block, a fish head cutting knife, a fish head cutting knife motor, a fish head viscera collection port, a fish tail cutting knife, a fish tail cutting knife motor, an electrical control cabinet, a transmission motor, a fish body segmentation collection port, a fish body segmentation knife, a fish head separation component, a conveyor belt, a viscera removal component, a fish belly cleaning component, and a fish tail collection port. However, it still requires manual adjustment during use, so the problem of low fish-killing efficiency still exists. Utility Model Content

Detailed Implementation

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] Example:

[0034] like Figures 1 to 4 As shown, in order to solve the above problems, this embodiment discloses a fish killing machine, including a fish killing machine body and a fish head adjustment device 10. The fish head adjustment device 10 is disposed on one side of the fish killing machine body and includes a first frame 100, an adjustment table 101 and a reciprocating drive structure 102.

[0035] The adjustment platform 101 is provided with an adjustment cavity 103. The side of the adjustment platform 101 near the main body of the fish killing machine is provided with a fish outlet 104. One end of the fish outlet 104 is connected to the adjustment cavity 103, and the other end is configured to cooperate with the main body of the fish killing machine. The bottom surface of the adjustment cavity 103 is inclined, and the end of the adjustment cavity 103 near the fish outlet 104 is lower than the other end of the adjustment cavity 103. One end of the adjustment cavity 103 is provided with a fish pouring part 105, and the other end is provided with a number of guide grooves 106. One end of the number of guide grooves 106 is configured to cooperate with the fish pouring part 105, and the other end is configured to cooperate with the fish outlet 104.

[0036] The reciprocating drive structure 102 includes a drive member 107 and a pair of sliding members 108. The pair of sliding members 108 are fitted together on the first frame 100. The adjustment table 101 is mounted on the pair of sliding members 108 and is slidably connected to the first frame 100 through the pair of sliding members 108. The drive member 107 is mounted on the first frame 107 and is fitted together with the adjustment table 101 to drive the adjustment table 101 to reciprocate.

[0037] This invention achieves fish head orientation adjustment by incorporating a fish head adjustment device 10, ensuring a uniform orientation for the fish heads. During operation, the adjustment platform 101 is driven to slide back and forth on the first frame 100 via a drive component 107. Simultaneously, utilizing the weight of the fish head compared to the tail and the inertia of the adjustment platform 101's reciprocating motion, the fish head is directed towards the outlet 104, thus achieving automatic fish head orientation adjustment. This solves the problem of current fish-killing machines failing to automatically adjust the fish head position during the killing process, requiring manual adjustment and resulting in low killing efficiency.

[0038] As a further preferred option, the bottom surface of the adjustment cavity 103 is tilted at an angle of 3-5°.

[0039] like Figures 4 to 5 As shown, in order to facilitate the stable reciprocating sliding of the adjustment platform 101 on the first frame 100, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that a pair of sliding members 108 are respectively disposed on both sides of the top of the first frame 100. The sliding member 108 includes a baffle 109 and a pair of sliding structures 110. The pair of sliding structures 110 are respectively located at both ends of the first frame 100. The baffle 109 is sleeved on the pair of sliding structures 110 and is slidably connected to the first frame 100 through the pair of sliding structures 110. The bottom sides of the adjustment platform 101 are respectively detachably connected to the baffle 109 of the pair of sliding members 108 by bolts.

[0040] The sliding structure 110 includes a fixed slide rail 111 and a connecting slider 112. The fixed slide rail 111 is fixedly connected to the first frame 100 by bolts. The connecting slider 112 is sleeved on the fixed slide rail 111 and is slidably connected to the fixed slide rail 111. The baffle 109 is fixedly connected to the connecting slider 112.

[0041] During use, the baffle 109 provides waterproof protection for the fixed slide rail 111 and the connecting slider 112, preventing them from getting wet and affecting their sliding performance. The fixed slide rail 111 and the connecting slider 112 also facilitate the reciprocating sliding of the adjustment table 101 on the first frame 100.

[0042] like Figure 4 As shown, to facilitate the reciprocating sliding of the adjustment platform 101 on the first frame 100, this embodiment improves upon the above embodiment. The difference lies in that the driving component 107 includes a drive motor 113, an eccentric block 114, a connecting arm 115, and a rotating connecting seat 116. The drive motor 113 is positioned below the adjustment platform 101 on the side away from the main body of the fish-killing machine. A fixed mounting plate 117 for mounting the drive motor 113 is provided on the first frame 100. The fixed mounting plate 117 is connected to the first frame 100. The drive motor 113 is fixedly connected to the bottom of the fixed mounting plate 117. The output shaft of the drive motor 113 passes through the fixed mounting plate 117 and is rotatably connected to the fixed mounting plate 117. One end of the eccentric block 114 is fixedly mounted on the output shaft of the drive motor 113, and the top of the other end of the eccentric block 114 is fixedly mounted with an eccentric shaft 118. One end of the connecting arm 115 is rotatably connected to the eccentric shaft 118, and the other end is rotatably connected to the rotating connecting seat 116. The rotating connecting seat 116 is fixedly mounted at the bottom of the adjusting table 101.

[0043] In use, when the drive motor 113 starts, its output shaft rotates, causing the eccentric block 114 to rotate. The eccentric shaft 118 on the eccentric block 114 moves in a circular motion with the eccentric block 114. The circular motion of the eccentric shaft 118 is converted into the linear reciprocating motion of the rotating connecting seat 116 through the connecting arm 115. The rotating connecting seat 116 is fixed to the bottom of the adjustment table 101, thereby driving the adjustment table 101 to make linear reciprocating motion, which helps to adjust the position of the fish's head.

[0044] The fixed mounting plate 117 is provided with a protective shell 119 for protecting the drive motor 113. The protective shell 119 is sleeved on the outside of the drive motor 113, and one end of the protective shell 119 is detachably connected to the bottom of the fixed mounting plate 117 by bolts. The protective shell 119 serves to protect the drive motor 113 from impact.

[0045] like Figure 3As shown, in order to facilitate the improvement of the fish's sliding ability, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that a water spray pipe 120 is provided on one side of the first frame 100. One end of the water spray pipe 120 is a water spray part 121, and the other end is a connecting part 122. The water spray part 121 is located above the adjustment platform 101. The water spray part 121 is provided with a plurality of water spray nozzles 123 that cooperate with the adjustment cavity 103. The connecting part 122 is detachably connected to one side of the first frame 100 through at least one pair of connectors. The end of the connecting part 122 can be connected to an external water supply pipe.

[0046] The water supply pipe is connected to the external water supply pipe at the connection part 122 of the water spray pipe 120. Water enters the water spray part 121 through the connection part 122 and is sprayed out from several water spray nozzles 123 on the water spray part 121 to rinse and wet the fish in the adjustment cavity 103 on the adjustment platform 101, thereby improving the fish's sliding ability and facilitating the adjustment of the fish's head position.

[0047] The connector includes a fixed bracket 124 and a fixed block 125. One end of the fixed bracket 124 is fixedly connected to one side of the first frame 100, and the other end is detachably connected to the fixed block 125 by bolts. Both the fixed bracket 124 and the fixed block 125 are provided with arc-shaped grooves 126 that mate with the connecting part 122. The connecting part 122 is fixed between the arc-shaped grooves 126 on the fixed bracket 124 and the fixed block 125. The connector facilitates the installation of the water spray pipe 120.

[0048] like Figure 3 As shown, in order to facilitate the collection of excess water, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that the bottom of the adjustment platform 101 is provided with a plurality of drainage holes 127, which penetrate the bottom of the adjustment platform 101 and are connected to the adjustment cavity 103.

[0049] The bottom of the adjustment platform 101 is provided with a water receiving trough 128. One end of the water receiving trough 128 is fixedly connected to the first frame 100, and the other end extends to the main body of the fish killing machine. The bottom of the water receiving trough 128 is provided with a water outlet 129. The water outlet 129 is located between the first frame 100 and the main body of the fish killing machine. Both ends of the water receiving trough 128 are inclined towards the water outlet 129.

[0050] During use, several drainage holes 127 at the bottom of the adjusting platform 101 drain water used for rinsing fish into a water receiving trough 128. The two ends of the water receiving trough 128 are inclined towards the outlet 129, allowing water to drain out from the outlet 129 under gravity. This prevents water from accumulating in the adjusting platform 101 and the water receiving trough 128, facilitating the collection of excess water. A wastewater recycling tank can be placed below the outlet 129 to recycle wastewater.

[0051] like Figure 1As shown, in order to improve the efficiency of fish killing, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that the main body of the fish killing machine includes a second frame 20, a conveying component 30, a head and tail removal component 40, and an internal organ suction component 50. The second frame 20 is set on one side of the fish head adjustment device 10. One end of the second frame 20 is configured to cooperate with the fish head adjustment device 10. The head and tail removal component 40 and the internal organ suction component 50 are set on the other end of the second frame 20. The conveying component 30 is set on the second frame 20. One end of the conveying component 30 is configured to cooperate with the fish head adjustment device 10, and the other end is configured to cooperate with the head and tail removal component 40 and the internal organ suction component 50. The conveying component 30 is used to convey fish, the head and tail removal component 40 is used to remove the fish head and tail, and the internal organ suction component 50 is used to suck the internal organs of the fish. The second frame 20 is also provided with a spraying component configured to cooperate with the head and tail removal component 40.

[0052] like Figure 6 As shown, the side of the second frame 20 closest to the fish head adjustment device 10 is the first mounting frame 200, which is used to install the conveying component 30. One end of the conveying component 30 can be installed on the first mounting frame 200. The side of the second frame 20 furthest from the fish head adjustment device 10 is the platform 201 and the second mounting frame 202. The platform 201 is located at the end of the second frame 20 closest to the fish head adjustment device 10 and is used by workers to adjust the position of the fish head. The second mounting frame 202 is located on the side of the platform 201. The second mounting frame 202 is provided with a mounting box 203 for installing the head and tail removal component 40 and the viscera suction component 50. The head and tail removal component 40 and the viscera suction component 50 can be installed in the mounting box 203. The other end of the conveying component 30 can be installed on the mounting box 203 and is configured to cooperate with the head and tail removal component 40 and the viscera suction component 50.

[0053] In use, by setting up a conveying component 30, a head and tail removal component 40, and an internal organ suction component 50, the conveying component 30 is used to convey the fish, the head and tail removal component 40 is used to remove the fish head and tail, and the internal organ suction component 50 is used to suck up the fish's internal organs, which can achieve a fast and efficient fish killing process.

[0054] As a further preferred embodiment, the mounting box 203 is equipped with a protective cover, which is configured in conjunction with the head and tail removal assembly 40 and the viscera suction assembly 50 to prevent the head and tail removal assembly 40 from causing injury to workers. The protective cover is not shown in the figure; any existing protective cover capable of achieving the function of this invention may be used.

[0055] like Figure 6As shown, to further improve fish-killing efficiency, this embodiment improves upon the above embodiment. The difference lies in that the conveying assembly 30 includes a first conveyor belt 300, a second conveyor belt 301, a first conveying drive structure 302, and a second conveying drive structure 303. The first conveying drive structure 302 includes a first driving wheel 304, a first driven wheel 305, and a first motor 306. The first motor 306 is fixedly installed inside the mounting box 203. The output shaft of the first motor 306 passes through one side of the mounting box 203 and is rotatably connected to it. The first driving wheel 304 is fixedly installed at the end of the output shaft of the first motor 306. The first mounting bracket 200 has a first rotating shaft 307 at one end of the fish head adjustment device 10, and the first rotating shaft 307 is fixedly connected to the first mounting bracket 200. The first driven wheel 305 is rotatably mounted on the first rotating shaft 307. The first conveyor belt 300 is sleeved on the outside of the first driving wheel 304 and the first driven wheel 305. The second conveying drive structure 303 includes a second driving wheel 308 and a second driven wheel 309. The second driving wheel 308 is rotatably mounted on the first rotating shaft 307 and one end is fixedly connected to the first driven wheel 305. The second driving wheel 308 can rotate synchronously with the first driven wheel 305. The mounting box 203 is provided with a second rotating shaft 310. The second rotating shaft 310 is located on one side of the first driving wheel 304. One end of the second rotating shaft 310 is fixedly connected to the mounting box 203. The second driven wheel 309 is rotatably mounted on the other end of the second rotating shaft 310. The second conveyor belt 301 is sleeved on the outside of the second driving wheel 308 and the second driven wheel 309.

[0056] The first mounting bracket 200 has an inclined guide plate 204 on one side that cooperates with the fish outlet 104. The inclined guide plate 204 has a number of guide conveying grooves 205 that cooperate with the guide slide 106. The first conveyor belt 300 and the second conveyor belt 301 each have a number of partition grooves 311 that cooperate with the guide conveying grooves 205.

[0057] The first mounting frame 200 is equipped with a limiting baffle 206, which is configured to cooperate with the dividing groove 311 on the second conveyor belt 301 to prevent fish from sliding out of the dividing groove 311 when they fall from the guide conveyor 205. When a fish slides down from the guide conveyor 205, its head contacts the limiting baffle 206, thus stopping it in the dividing groove 311.

[0058] In use, after adjusting the position of the fish head, the fish enters the guide conveyor trough 205 through the guide chute 106 and the fish outlet 104, and then enters the separation groove 311 on the first conveyor belt 300 and the second conveyor belt 301. The fish head is located in the separation groove 311 on the second conveyor belt 301, the fish body is located in the separation groove 311 on the first conveyor belt 300, and the fish tail is located outside the separation groove 311. Then, the first motor 306 drives the first drive wheel 304, which drives the first conveyor belt 300 and the first driven wheel 305. One end of the first driven wheel 305 is fixedly connected to the second drive wheel 308. When the first driven wheel 305 rotates, it drives the second drive wheel 308 to rotate. The rotation of the second drive wheel 308 then drives the second conveyor belt 301 and the second driven wheel 309, so that the fish in the separation groove 311 passes through the head and tail removal assembly 40 and the internal organ suction assembly 50 in sequence, completing the process of removing the head, tail, and internal organs.

[0059] It should be noted that the first conveyor belt 300 can be connected to the first driving pulley 304 and the first driven pulley 305 using friction drive or meshing structure, as is available in the prior art. Similarly, the second conveyor belt 301 can be connected to the second driving pulley 308 and the second driven pulley 309 using friction drive or meshing structure, as is available in the prior art.
