Description

Technical Field

[0001] This utility model relates to the field of production and processing technology, and in particular to an automated fish-killing device. Background Technology

[0002] A fish-killing machine is a professional tool that automatically scales, guts, and cleans fish. As a key link in aquatic product processing, the degree of automation of fish slaughtering and processing directly affects production efficiency and hygiene standards. Traditional manual fish-killing operations suffer from problems such as high labor intensity, low efficiency, and high hygiene risks. Fish-killing machines can greatly solve the problems of manual fish-killing and improve efficiency.

[0003] While automated fish-killing equipment can partially replace manual labor in current technologies, several problems remain. First, the conveyor mechanism of existing equipment lacks an effective limiting structure, making it prone to lateral shifting or axial rotation during transport. This prevents the blades from precisely targeting specific areas (such as the gills or abdomen), requiring repeated adjustments or manual intervention, reducing operational continuity, and easily damaging fish quality due to operational deviations. Second, cleaning and maintenance are difficult. Fish blood and visceral residue accumulate in the gaps of the conveyor belt and limiting structure after slaughter, breeding bacteria and contaminating subsequent fish. Existing equipment largely relies on manual rinsing or cleaning during downtime, increasing labor costs and posing a risk of cross-contamination due to incomplete cleaning, thus affecting product hygiene and safety.

[0004] Chinese utility model patent CN222737141U discloses a multi-functional fish-killing machine. The device uses a fixed fish-pressing component to compress and limit the fish. However, the fixed mechanism is difficult to adapt to fish of different sizes (such as slender ribbonfish and wide pomfret). The entire transmission line needs to be replaced or a special equipment needs to be customized, resulting in high modification costs, poor production line flexibility, and inability to meet the needs of multi-variety, small-batch production. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model proposes an automated fish-killing device.

[0006] To achieve the above objectives, this utility model proposes an automated fish-killing device, the specific technical solution of which is as follows.

[0007] An automated fish-killing device includes a body and a transmission mechanism that runs through the body. The transmission mechanism is driven by a motor. The body is equipped with a processing device. The surface of the transmission mechanism is equipped with a detachable fish-limiting device. The fish-limiting device includes a base plate and limiting plates symmetrically arranged on the base plate. The base plate and the limiting plates together form a V-shaped cavity with openings at the top and both ends. The V-shaped angle of the cavity restricts the lateral displacement and axial rotation of the fish. The bottom of the cavity base plate is equipped with a connecting structure for mounting the fish-limiting device on the surface of the transmission mechanism.

[0008] When the device is started, the user can select fish limiting devices of different sizes and widths according to the fish species to be processed, and conveniently install them on the surface of the transmission mechanism. The number of fish limiting devices can be increased or decreased according to actual production needs, so that fish limiting devices can be replaced without the need for customized special equipment.

[0009] Furthermore, the connection structure between the base plate and the surface of the transmission mechanism is a snap-fit ​​protrusion. This protrusion engages with the embedding hole on the transmission mechanism to form a snap-fit, thus fixing the fish limiting device to the surface of the transmission mechanism.

[0010] The connection structure between the base plate and the surface of the transmission mechanism is a plug-in piece. This plug-in piece cooperates with the plug-in slot on the transmission mechanism to form a plug-in connection, thereby fixing the fish limiting device to the surface of the transmission mechanism.

[0011] By providing different connection methods to adapt to different production environments, if the transmission mechanism is a transmission chain, the snap-fit ​​protrusion of the fish limiting device is snapped into the transmission chain by means of snap-fit ​​protrusion and embedding hole. If the transmission mechanism is a conveyor belt, the plug-in component is used to fix the plug-in slot on the conveyor belt. In this way, the fish limiting device can be replaced and used simply by snapping / plugging it into the plug-in slot.

[0012] Furthermore, the transmission mechanism is a transmission chain spliced ​​together by connectors. The connectors are long strips with radially expandable pins. The length and / or width of the transmission chain can be adjusted by adding or removing chain segments formed by the connectors.

[0013] In existing technologies, transmission chains are often of fixed length and width. If the production site is narrow, repeated replacements and adjustments are required, wasting manpower and resources. By using transmission chains composed of connectors, the required width and length of transmission chain can be obtained simply by adjusting the connectors, thus solving the problem of repeated debugging.

[0014] Furthermore, the limiting plates on both sides of the fish limiting device are set in an inward-contracting shape from the inlet end to the outlet end, maintaining a small constant angle.

[0015] Furthermore, the limiting plates on both sides of the fish limiting device are set outward from the inlet end to the outlet end, maintaining a large constant angle.

[0016] Furthermore, the limiting plates on both sides of the fish limiting device are hinged to the base plate through a rotating shaft mechanism, so that the angle of the limiting plates on both sides can be adjusted and locked.

[0017] Furthermore, a fixed baffle is provided at the tail end of the fish limiting device to permanently seal the tail end of the fish limiting device.

[0018] Furthermore, the machine body is equipped with a rinsing unit, which includes a base and a nozzle. This unit is located downstream of the processing device and is triggered by the control system to spray water. The nozzle is a hollow tube, and the water supply pipe is integrated into the base and connected to the water source. The rinsing unit sprays the processed fish and the fish-limiting device and transmission mechanism that carry them.

[0019] By placing the rinsing unit downstream of the treatment device, the fish can be directly cleaned after processing, avoiding siltation and the hygiene problems caused by it.

[0020] Furthermore, the fish limiting device is 600-800mm long and 100-150mm wide, with a 50-70° angle between the two limiting plates.

[0021] In summary, this utility model has the following beneficial technical effects:

[0022] The V-shaped fish limiting device effectively restricts the position of fish, preventing them from shifting or flipping during transport, thus improving the accuracy and efficiency of fish killing operations. It also allows for timely cleaning of stains on the conveyor belt in the rinsing unit, ensuring equipment hygiene, preventing fish contamination, reducing subsequent cleaning difficulties, and guaranteeing fish quality. The modular design of the V-shaped limiting device and conveyor belt allows for adjustment of length and width according to actual needs, making it highly adaptable. The overall device has a compact structure, with all parts working collaboratively, improving the automation level and overall efficiency of fish killing operations. Furthermore, its simple structure and easy installation make it suitable for industrial-scale promotion. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Example 1

[0032] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments of the present invention and the features thereof can be combined with each other.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0034] like Figure 1 As shown in the figure, the overall structure of this utility model is mainly composed of the body 1, which serves as the frame of the machine, the transmission mechanism 2, the fish limiting device 3, and the processing device 4. The processing device is a knife, which is attached to the body 1 by an elastic rope. Workers can use the knife to cut open the belly of the fish.

[0035] When fish enter the conveying mechanism 2, the fish to be processed are fixed and limited by the fish limiting device 3 set on the conveying mechanism 2. Then, the conveying mechanism 2 transports the fixed fish to the corresponding work station of the processing device 4. The processing device 4 performs fish-killing operations such as cutting. After the processing is completed, the fish are sent out through the conveying mechanism 2.

[0036] In this embodiment, the transmission mechanism 2 consists of a servo motor 21 and a transmission chain 22. The transmission chain 22 is connected to the gear on the output shaft of the servo motor 21 through meshing. The servo motor 21 is preferably located at both ends of the transmission chain 22. When the servo motor 21 is running, it drives the transmission chain 22 to perform chain drive motion.

[0037] In this embodiment, the transmission chain 22 is configured as a detachable structure. Specifically, chain segments or links can be spliced ​​together via connectors 221. Connectors 221 are elongated pins with a radially expandable structure. By adding or removing connectors 221 or chain segments, the length and / or width of the transmission chain 22 can be adjusted according to actual fish-killing needs. Furthermore, in the assembly structure of the transmission chain 22, such as... Figure 3 As shown, the transmission chain 22 is provided with an embedding hole 222, and the bottom of the fish limiting device 3 is provided with a corresponding snap-fit ​​protrusion 33. The snap-fit ​​protrusion 33 is preferably spherical, but other suitable shapes can also be used. The snap-fit ​​protrusion 33 can be fitted into the embedding hole 222 of the transmission chain 22, thereby detachably fixing the fish limiting device 3 to the transmission chain 22.

[0038] The aforementioned transmission mechanism 2 is not limited to chain drive; the transmission chain 22 can also be replaced by a transmission belt 23. The drive wheel is driven by the servo motor 21, and the driven wheel is driven by the transmission belt 23 to realize belt drive transportation of objects.

[0039] like Figure 4 As shown, when the transmission mechanism 2 is configured as a conveyor belt 23, the detachable fixing method of the fish limiting device 3 is changed accordingly. A plug-in component with a plug-in groove 221 is provided on the belt surface of the conveyor belt 23. At this time, the bottom of the fish limiting device 3 is changed from a snap-fit ​​protrusion 33 to a plug-in piece 34 that matches the plug-in groove. By sliding the plug-in piece 34 into the plug-in groove 231 of the plug-in component, the fish limiting device 3 can be detachably fixed. The reason for this setting is to facilitate replacement. By adjusting the number of plug-in components provided on the transmission belt 23, the number of fish limiting devices 3 installed on it can be adjusted according to the actual fish killing needs. This adjustable design concept is common to the aforementioned embodiment of the transmission chain 22. Both are achieved by optimizing the size of the transmission mechanism 2 and / or the number of fish limiting devices 3 according to actual needs through the detachable / configurable characteristics of the transmission mechanism 2 itself and the bottom connection structure of the fish limiting device 3, so as to adapt to different fish killing production needs. Chain drive and belt drive exist as two parallel implementation methods of the transmission mechanism 2 of this utility model.

[0040] like Figure 2 , 3 As shown, the fish limiting device 3 of this utility model is mainly composed of limiting plates 31 on the left and right sides and a bottom plate 32, which together form a V-shaped non-closed accommodating chamber. The front end of the chamber, its opposite rear end, and the top are all open. The whole structure is open from front to back, with a single passage at the top and a closed bottom. When in use, the fish to be processed can be placed into the accommodating chamber from the front / rear end, or it can be placed from the top.

[0041] The base plate 32 is provided with several fixing structures for cooperating with the transmission mechanism 2. Through these fixing structures, which have been detailed above, and in cooperation with the embedding holes 222 of the transmission chain 22 or the insertion slots 231 of the transmission belt 23, the fish limiting device 3 is detachably fixed to the transmission mechanism 2. According to different actual production needs on site, the fish limiting device 3 can be designed and replaced according to the target fish species and processing needs.

[0042] In this embodiment, the fish-limiting device 3 is configured with a length of approximately 700mm, a width of approximately 125mm, and an angle of approximately 60° between the two limiting plates 31. Actual testing shows that this size and angle effectively constrain the position of the fish in the automated fish-killing process, significantly reducing its offset and flipping during transport, thereby improving the accuracy and efficiency of the fish-killing operation. Furthermore, thanks to the detachable fixing method, the number of fish-limiting devices 3 can be flexibly increased or decreased to adapt to different production cycles and environmental requirements, enhancing the overall adaptability of the equipment.

[0043] It should be understood that although one of the core innovations of this application lies in the modular and detachable design of the fish limiting device 3 and the resulting adjustability, the implementation mode of the fish limiting device 3 being directly fixed to the transmission mechanism 2 by means of welding, riveting, etc., is also within the scope of the technical solution of this application.

[0044] To further improve the fish-limiting effect or adapt to different working conditions, the fish-limiting device 3 of this utility model provides the following four preferred structural embodiments:

[0045] The first embodiment is an inwardly narrow-mouth type, with the two side limiting plates 31 arranged in an inwardly contracting shape from the inlet end to the outlet end, that is, the included angle gradually decreases or maintains a small constant angle, forming a relatively narrow fish body channel. This structure has the strongest restraining force on the fish body and the best limiting effect, which can effectively prevent the fish body from swinging violently during high-speed conveying or processing, and is especially suitable for fish species with slender bodies or those that are easy to slip out.

[0046] The second embodiment is an outwardly widened opening type. Unlike the first embodiment, the two side limiting plates 31 are arranged in an outwardly expanding shape from the inlet end to the outlet end, that is, the included angle gradually increases or maintains a large constant angle, forming a relatively spacious fish body passage. This structure facilitates the smooth entry of fish, improves the passage of the inlet, and at the same time still has a basic restraining effect on the fish body, preventing it from shifting or turning over significantly laterally. It is suitable for fish species with wider bodies or those that require rapid feeding.

[0047] The third embodiment is an adjustable hinge type. Unlike the first and second embodiments, the two side limiting plates 31 are no longer fixedly set, but are instead independently and movably connected to the base plate 32 via hinges or equivalent hinge / rotating shaft mechanisms, making the angle of the limiting plates 31 adjustable. This structure has the function of both narrow and wide opening modes, and can provide two working modes:

[0048] Narrow-mouth working mode: Rotate the limiting plate 31 inward to a smaller included angle position and lock it.

[0049] Wide-mouth working mode: Rotate the limiting plate 31 outward to a larger included angle position and lock it.

[0050] The third embodiment is the most flexible, capable of switching the channel width in real time according to the needs of different fish species or processes, but its structure is relatively complex and its cost is high.

[0051] Meanwhile, based on the first embodiment and the second embodiment, a fourth embodiment is added: a tail-closed fish-limiting device. Specifically, based on the fixed angle structure of the first or second embodiment, which is either an inwardly narrowed or outwardly widened opening, a fixed baffle 35 is added to the tail end of the fish-limiting device 3. By sealing the tail of the cavity, the space for the fish to slide backward or flick its tail is eliminated, significantly enhancing the rigid constraint on the tail of the fish, ensuring that it is fixed in the position of the fish at the key processing station, and greatly improving the operational accuracy.

[0052] To ensure the cleanliness and hygiene of the equipment and prevent the accumulation of residues, such as Figure 1 , 2 As shown, a rinsing unit 5 is added downstream of the processing device 4. The figure shows the specific structure of the rinsing unit 5 in this utility model. The main structure of the rinsing unit 5 consists of multiple independent nozzles 52 and corresponding bases 51. The number of nozzles 52 and corresponding bases 51 are preferably arranged one-to-one with the work stations of the processing device 4.

[0053] Specifically, the nozzle 51 has a hollow tubular structure and is detachably fixed to the base 51 by threaded connectors, which facilitates maintenance and replacement.

[0054] Water supply pipe 511 is built into base 51. Water is supplied to nozzle 5 through this pipe. When the fish that have been treated and the fish limiting device 3 / transfer mechanism 2 carrying them pass through the station, the control system is activated. Water is sprayed out from nozzle 52 to perform rinsing. The spraying stops automatically after a predetermined time and waits for the next trigger.

[0055] In this embodiment, the installation position of the rinsing unit 5 is not unique, and two installation embodiments are provided here.

[0056] The first embodiment is an upward installation. When the rinsing unit 5 is installed above the body 1, the nozzle 52 mainly sprays water downward or diagonally downward. Its rinsing force is concentrated on covering the inside and surface of the non-enclosed cavity of the fish limiting device 3 below it, which can efficiently remove residual fish blood, internal organ fragments, etc., and especially perform deep cleaning on the fish limiting device 3.

[0057] The second embodiment is a side-mounted installation. When the rinsing unit 5 is installed on the side of the body 1, the nozzle 52 mainly sprays water along the horizontal or inclined direction. Its rinsing range is wider and can simultaneously cover the surface of the transmission mechanism 2 and the side and part of the bottom surface of the fish limiting device 3, realizing synchronous cleaning of the transmission path. However, relatively speaking, the rinsing intensity of the inside of the fish limiting device 3 cavity is weaker than that of the top-mounted method.

[0058] It should be understood that the specific selection of the rinsing unit 5 according to the embodiment can be based on the cleaning priorities in actual production, such as focusing on deep cleaning of the fish limiting device, focusing on conveyor belt maintenance or comprehensive cleaning, and can be flexibly configured and combined according to production costs and space layout.

[0059] In summary, such as Figure 1 As shown, the automated operation process of this utility model is as follows: the user places the fish to be processed into the fish-limiting device 3 on the operating transmission mechanism 2 to complete the fixed limiting. The transmission mechanism 2 starts directional conveying and transports the fish-limiting device 3, which fixes the fish body, to the corresponding work station of the processing device 4. The processing device 4 performs fish-killing operations such as dissection on the fish in the limited state. After the processing is completed, the transmission mechanism 2 continues to convey and sends the fish-limiting device 3 carrying the processed fish to the rinsing unit 5 work station. The control system triggers the nozzle 52 of the rinsing unit 5 to spray water to rinse the cavity of the fish-limiting device 3, the transmission mechanism 2 and the fish body. After cleaning, the transmission mechanism 2 sends the fish body out of the equipment to complete the operation.

[0060] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.

[0061] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
