Description

Technology Field

[0001] The present invention relates to a fish cutting device, and more specifically, to a fish cutting device configured such that a pair of rotary cutting parts and a cut material transport part operate in conjunction by rotational operation of a user to cut a fish and discharge the cut fish to the outside. Background Technology

[0002] Generally, fish used as fishing bait are often cut into a specific size or shape, and for this purpose, the method of workers directly cutting the fish using knives or similar tools has been widely used. However, this method has several drawbacks: the size of the cut fish may vary depending on the worker's skill level, repetitive cutting tasks require significant time and effort, and there is a risk of safety accidents during the process.

[0003] To solve these problems, various fish cutting devices for automatically or semi-automatically cutting fish have been proposed. For example, Registered Patent Publication No. 10-2449690 discloses a fish cutting device that transports fish by placing a chain conveyor inside a housing and cuts the fish by placing a rotating cutting blade on top of the conveyor. Furthermore, the device is configured to cut the fish while maintaining a fixed position using a pressure body so that the fish does not shake during the cutting process.

[0004] However, such conventional fish cutting devices require a power source and power transmission structure to operate the conveyor and cutting blades, resulting in a complex device structure that may be difficult to use conveniently in places like fishing sites where power supply is difficult. Furthermore, it is difficult to operate the fish cutting component and the cut fish transport component together with a single manual operation, and since the cutting component that comes into direct contact with the fish is installed inside the main body, cleaning or maintenance may be inconvenient. Prior art literature

[0005] Registered Patent Publication No. 10-2449690 (Registered September 27, 2022) The problem to be solved

[0006] The present invention was developed to improve upon the aforementioned problems, and the objective of the present invention is to provide a fish cutting device configured such that a pair of rotary cutting parts and a cut material transport part operate in conjunction by rotational operation of a user to cut a fish and discharge the cut fish to the outside. means of solving the problem

[0007] The present invention is characterized by comprising: a main body (100) configured to allow fish to be fed through the upper part and having a fish discharge port (130) formed on one side; a cutting unit (200) provided in the main body (100) and having a first rotary cutting unit (230a) and a second rotary cutting unit (230b) each including a plurality of cutting blades (231) and arranged so that the cutting blades (231) on both sides intersect each other; a cutting material transport unit (300) provided at the lower part of the cutting unit (200) for transporting the cut fish to the fish discharge port (130); an interlocking unit (400) for linking the rotation of the first rotary cutting unit (230a) and the second rotary cutting unit (230b) with the operation of the cutting material transport unit (300); and an operating unit (500) that is rotated by a user to transmit rotational force to the interlocking unit (400).

[0008] Meanwhile, the cutting unit (200) further includes a cutting unit housing (210) that is detachably coupled to the main body (100), and the first rotary cutting part (230a) and the second rotary cutting part (230b) are rotatably coupled to the cutting unit housing (210).

[0009] At this time, the cutting unit housing (210) may be configured to be pulled out to the side of the main body (100) and separated.

[0010] In addition, the cutting unit housing (210) is formed with a first shaft coupling hole (244a) to which the first rotary cutting part (230a) is coupled; and a second shaft coupling hole (244b) to which the second rotary cutting part (230b) is coupled and which is formed extending in the front-rear direction. The second shaft coupling hole (244b) may be formed so that the second rotary cutting part (230b) can move between an assembly position where the cutting blades (231) on both sides do not intersect each other and an operating position where the cutting blades (231) on both sides intersect each other.

[0011] Meanwhile, the cutting unit (200) is configured to guide the fish cut by the first rotary cutting unit (230a) and the second rotary cutting unit (230b) to the cut material transport unit (300), and may further include a cut material guide unit (240) detachably connected to the cutting unit (200).

[0012] At this time, the cutting guide portion (240) is formed with a plurality of blade insertion grooves (241) into which a plurality of cutting blades (231) of the first rotary cutting portion (230a) or the second rotary cutting portion (230b) are respectively inserted, and the cutting guide portion (240) is supported on the outside of the rotation axis (232) of the corresponding first rotary cutting portion (230a) or the second rotary cutting portion (230b). Effects of the invention

[0013] The fish cutting device according to the present invention allows the first rotary cutting unit, the second rotary cutting unit, and the cut material transport unit to operate together by the user rotating the control unit, thereby enabling the continuous cutting of fish and the transport of the cut fish without the use of a separate motor or power source. Accordingly, the device can be miniaturized and can be conveniently used even at fishing sites where power supply is difficult.

[0014] In addition, since multiple cutting blades on both sides are arranged to intersect and rotate to cut the fish, the input fish can be quickly cut into multiple pieces. The cut material guide prevents the cut fish from getting stuck between the cutting blades or moving along the blades, and guides it to the cut material transport section, thereby allowing the cut fish to be discharged smoothly.

[0015] In addition, the cutting unit can be withdrawn and separated from the side of the main body, and the cut guide can be separated individually, allowing for easy cleaning or maintenance of the parts that come into direct contact with the fish. Furthermore, the front, rear, and left and right sides of the main body can be separated, and cleaning water and residue can be discharged through the open bottom, enabling hygienic maintenance of the device's interior.

Specific details for implementing the invention

[0017] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings so that a person skilled in the art to which the present invention pertains can easily practice the present invention.

[0018] The fish cutting device (10) according to the present invention is for cutting a fish into a certain size, and more specifically, it relates to a fish cutting device (10) configured such that cutting of the fish and transport of the cut fish are performed together by a user rotating the operating part (500).

[0019] As illustrated in FIG. 1, the fish cutting device (10) according to the present invention is for cutting a fish into a certain size, and more specifically, it relates to a fish cutting device (10) configured such that cutting of the fish and transport of the cut fish are performed together by a user rotating the operating part (500).

[0020] As shown in FIG. 2, the present invention comprises a main body (100), a cutting unit (200), a cut material transport unit (300), an interlocking unit (400), and an operating unit (500). Hereinafter, the direction in which the fish is discharged is referred to as the front, and the opposite direction is referred to as the rear. Additionally, the front-rear direction corresponds to the Y-axis direction shown in the drawing, and the left-right direction corresponds to the X-axis direction shown in the drawing. These directions are set to aid in understanding the invention and are not limited thereto.

[0021] Referring to FIGS. 2 and 3, the main body (100) forms the outer shape of the fish cutting device (10) and provides a space for installing a cutting unit (200), a cutting material conveying unit (300), and an interlocking unit (400) inside. A support structure (170) that supports the fish cutting device (10) on the installation surface may be provided at the bottom of the main body (100).

[0022] A main body opening (110) is formed at the upper part of the main body (100) to allow fish to be introduced inside, and a main body cover (120) covering the upper part of the main body (100) may be provided at the main body opening (110) so as to be openable, closable, or detachable. A plurality of ventilation holes for drying after washing may be formed in the main body cover (120). A handle for moving the device may be further provided at the upper part of the main body (100).

[0023] A fish discharge port (130) for discharging cut fish to the outside is formed on the front of the main body (100), and an observation port (140) for checking the internal condition can be formed on the rear of the main body (100).

[0024] The main body (100) may be configured such that the front, rear, and left and right sides are each separable, and may be formed with an open bottom. Accordingly, at least one of the front, rear, and left and right sides of the main body (100) can be separated to access the interior of the main body (100), and cleaning water and residue generated during the cleaning process can be discharged to the outside through the open bottom of the main body (100).

[0025] A cutting unit mounting groove (150) through which a cutting unit (200), to be described later, passes may be formed through the left and right sides of the main body (100). An installation protrusion (160) that protrudes inwardly from the main body (100) and supports the outer surface of the cutting unit (200) may be formed around the perimeter of the cutting unit mounting groove (150). In addition, a protective cover for protecting the interlocking unit (400) and the operating unit (500), to be described later, may be detachably provided on the left and right sides of the main body (100).

[0026] Referring to FIGS. 2 and 4, the cutting unit (200) is provided inside the main body (100) and cuts a fish introduced through the top, and may include a cutting unit housing (210), a first rotary cutting part (230a), and a second rotary cutting part (230b).

[0027] The cutting unit housing (210) includes a pair of unit side walls (211) and a plurality of frames (212) connecting the unit side walls (211), and the unit side walls (211) can be installed so as to face the left and right sides of the main body (100).

[0028] The unit side wall (211) is formed in a plate shape, and a rim wall (213) protruding toward the outside of the cutting unit housing (210) may be formed at the edge. The rim wall (213) may be formed along the top, bottom, front, and rear ends of the unit side wall (211) to form a component receiving space (214) that is open to the outside on the outer surface of the unit side wall (211).

[0029] The cutting unit housing (210) is inserted into the interior of the main body (100) through the cutting unit mounting groove (150), and can be fixed to the main body (100) by a fastening member such as a bolt or screw while the rim wall (213) is supported by the installation protruding end (160).

[0030] As shown in FIGS. 4 and 5, an input guide cover (220) having a cover opening (221) formed on the upper part of the cutting unit housing (210) may be further provided. The input guide cover (220) is coupled to cover the upper part of the cutting unit housing (210) and guides fish between the first rotary cutting part (230a) and the second rotary cutting part (230b) through the cover opening (221). A portion that wraps around the front and rear surfaces of the cutting unit housing (210) is formed at the front and rear ends of the input guide cover (220) so that it can be fitted and coupled to the cutting unit housing (210).

[0031] The first rotary cutting section (230a) and the second rotary cutting section (230b) are spaced apart from each other so that fish can be fed between them. As shown in FIG. 6, the first rotary cutting section (230a) and the second rotary cutting section (230b) may each include a rotating shaft (232) rotatably coupled to the cutting unit housing (210) and a plurality of cutting blades (231) spaced apart along the axial direction of the rotating shaft (232). Both ends of each rotating shaft (232) may be rotatably supported on the unit side wall (211) by means of bearings, etc.

[0032] As illustrated in FIGS. 4 and 7, a first shaft coupling hole (244a) to which the rotation axis (232) of the first rotary cutting part (230a) is coupled and a second shaft coupling hole (244b) to which the rotation axis (232) of the second rotary cutting part (230b) is coupled may each be formed in a pair of unit side walls (211). The first shaft coupling hole (244a) may be formed in a circular shape so that the installation position of the first rotary cutting part (230a) is fixed, and the second shaft coupling hole (244b) may be formed as an elongated hole extending along the front-rear direction so that the second rotary cutting part (230b) can move in the front-rear direction. At this time, the fastening hole of the bearing supporting the rotation axis (232) of the second rotary cutting part (230b) may also be formed in the shape of an elongated hole extending in the front-rear direction to allow movement of the second rotary cutting part (230b).

[0033] When installing the first rotary cutting part (230a) and the second rotary cutting part (230b) in the cutting unit housing (210), the first rotary cutting part (230a) and the second rotary cutting part (230b) can be sufficiently spaced apart in the front-rear direction so that the cutting blades (231) on both sides do not intersect each other, and each rotary shaft (232) can be connected to the first shaft coupling hole (244a) and the second shaft coupling hole (244b), respectively. Accordingly, the first rotary cutting part (230a) and the second rotary cutting part (230b) can be easily installed in the cutting unit housing (210) without the cutting blades (231) on both sides interfering with each other.

[0034] After each rotation axis (232) is coupled to the first shaft coupling hole (244a) and the second shaft coupling hole (244b), the second rotary cutting part (230b) can move along the second shaft coupling hole (244b) toward the first rotary cutting part (230a). When the second rotary cutting part (230b) moves to the operating position, the cutting blade (231) of the first rotary cutting part (230a) enters between the adjacent cutting blades (231) of the second rotary cutting part (230b), so that the cutting blades (231) on both sides are arranged to intersect each other. Subsequently, the second rotary cutting part (230b) can be fixed to the operating position by means of a fastening member, etc.

[0035] Accordingly, the second shaft coupling hole (244b) allows the second rotary cutting part (230b) to move between an assembly position where the cutting blades (231) of the first rotary cutting part (230a) and the second rotary cutting part (230b) do not intersect each other, and an operating position where the cutting blades (231) on both sides intersect each other. Accordingly, the first rotary cutting part (230a) and the second rotary cutting part (230b) can be easily installed or separated while preventing interference or collision between the cutting blades (231).

[0036] Additionally, the second rotary cutting section (230b) can be fixed after the distance from the first rotary cutting section (230a) is adjusted at the operating position. Accordingly, the distance between the first rotary cutting section (230a) and the second rotary cutting section (230b) can be adjusted in response to the size of the fish or cutting conditions while maintaining the cutting blades (231) on both sides intersecting each other.

[0037] As shown in FIGS. 5 and 6, the first rotary cutting section (230a) and the second rotary cutting section (230b) may be provided with a spacer (233) that maintains the gap between adjacent cutting blades (231). By replacing the spacer (233) with one having a different axial length, the gap between the cutting blades (231) can be adjusted, and accordingly, the width of the fish being cut can be adjusted.

[0038] The ends of the rotation shafts (232) of the first rotary cutting section (230a) and the second rotary cutting section (230b), the interlocking gear (410), and the fastening member, etc., can be placed in the component receiving space (214) formed on the outer surface of the unit side wall (211). These components can be installed so that they do not protrude beyond the outer end of the perimeter wall (213) or the degree of protrusion is minimized. Accordingly, the width of the cutting unit (200) in the left-right direction can be reduced, and interference with surrounding structures can be reduced when installing the cutting unit (200) on the main body (100) or separating it from the main body (100).

[0039] As illustrated in FIG. 2, the cutting unit housing (210) can be withdrawn to the side of the main body (100) through the cutting unit mounting groove (150) when the connection with the main body (100) and the connection with the interlocking part (400) are released. Accordingly, the cutting unit (200) equipped with the first rotary cutting part (230a) and the second rotary cutting part (230b) can be separated from the main body (100) for cleaning or maintenance.

[0040] Meanwhile, the cutting unit (200) may be provided in multiple sizes according to the cutting specifications of the fish and may be selectively mounted on the main body (100). The cutting unit (200) of each size may be configured such that the spacing between the cutting blades (231) provided in the first rotary cutting section (230a) and the second rotary cutting section (230b) is different from each other. Accordingly, the user can select the cutting unit (200) corresponding to the required cutting width of the fish and mount it on the main body (100).

[0041] Meanwhile, a pair of cutting guides (240) may be detachably provided in the cutting unit (200). Each cutting guide (240) is positioned to correspond to the first rotary cutting section (230a) or the second rotary cutting section (230b) to prevent the cut fish from getting stuck between the cutting blades (231) or moving along the cutting blades (231) and to guide it to the lower cutting conveyor (300).

[0042] As illustrated in FIGS. 4 and 5, the cutting guide (240) is formed as a plate that is positioned to be inclined downward toward the cutting conveyor (300) and may include a plurality of blade insertion grooves (241) into which a plurality of cutting blades (231) of a corresponding rotary cutting section (230a or 230b) are each inserted. At least a portion of the cutting guide (240) may be supported by contacting the outside of the rotation axis (232) of the corresponding rotary cutting section. When a spacer (233) is provided, a portion of the cutting guide (240) located between the blade insertion grooves (241) may be supported by contacting the outer surface of the spacer (233).

[0043] The lower end of the cut guide section (240) is bent and extended toward the cut transport section (300) to guide the cut fish downward. Accordingly, the cut fish can be prevented from getting stuck between the cutting blade (231) and the rotation axis (232).

[0044] A locking coupling member (242) is formed at the top of the cutting guide member (240), and a locking coupling groove (243) into which the locking coupling member (242) is inserted may be extended and formed in the main body member (100) and the cutting unit housing (210). The locking coupling member (242) is supported so as to be rotatable while locked in the locking coupling groove (243).

[0045] When the installation position of the first rotary cutting part (230a) or the second rotary cutting part (230b) is changed, the corresponding cutting guide part (240) can rotate together to maintain contact with the outer surface of the rotation axis (232) or spacer (233). The cutting guide part (240) can be pulled upward and separated individually, or it can be separated together with the cutting unit (200) when the cutting unit (200) is pulled out to the side of the main body part (100).

[0046] As illustrated in FIG. 5, the cut material transport unit (300) is provided at the bottom of the cutting unit (200) and transports the cut fish to the fish discharge port (130). The cut material transport unit (300) may include a plurality of transport rollers (310) and a transport belt (320) wound around the transport rollers (310), and transports the fish dropped from the cutting unit (200) to the fish discharge port (130) by the transport belt (320).

[0047] As illustrated in FIGS. 2 and FIGS. 8, the interlocking unit (400) transmits the rotational force input to the operating unit (500) to the first rotary cutting unit (230a), the second rotary cutting unit (230b), and the cut material transport unit (300) to interlock the rotation of the first rotary cutting unit (230a) and the second rotary cutting unit (230b) and the operation of the cut material transport unit (300).

[0048] In one embodiment, the interlocking unit (400) may include a pair of interlocking gears (410) that are respectively coupled to the rotation axis (232) of the first rotary cutting unit (230a) and the rotation axis (232) of the second rotary cutting unit (230b) and mesh with each other. When the rotational force of the operating unit (500) is transmitted to one of the rotation axis (232), the rotational force is also transmitted to the other rotation axis (232) through the pair of interlocking gears (410).

[0049] The interlocking gear (410) can be interchangeably coupled to each rotation shaft (232). When the distance between the first rotational cutting section (230a) and the second rotational cutting section (230b) is adjusted, an interlocking gear (410) of a size corresponding to the adjusted inter-axis distance is interchangeably coupled to each rotation shaft (232) to maintain the meshing of the interlocking gears (410) on both sides.

[0050] The interlocking unit (400) may include a power transmission structure connecting the rotation axis (232) of the first rotary cutting unit (230a) or the second rotary cutting unit (230b) and the transfer roller (310) of the cut material transfer unit (300). The power transmission structure may include a belt pulley (420) coupled to the rotation axis (232) of the rotary cutting unit and the transfer roller (310), respectively, and a power transmission belt (430) connecting the belt pulley (420). The interlocking unit (400) is not limited thereto and may be configured to transmit rotational force using at least one of a gear, belt, chain, pulley, or sprocket.

[0051] As shown in FIGS. 1 and 2, the operating part (500) is rotated by a user to transmit rotational force to the linkage part (400), and may be formed as a crank-type handle that the user can grasp from the outside of the main body part (100). However, the operating part (500) may be formed in various shapes that allow the user to input rotational force.

[0052] The operating part (500) can be detachably attached to one end of the rotation axis (232) of the first rotary cutting part (230a) or the second rotary cutting part (230b) to increase convenience.

[0053] The operation process of the fish cutting device (10) is described below.

[0054] If the main body cover (120) is provided, the user opens or separates it and then inserts a fish through the main body opening (110). If the insertion guide cover (220) is provided, the fish is guided through the cover opening (221) between the first rotary cutting part (230a) and the second rotary cutting part (230b).

[0055] When the user rotates the control unit (500), the first rotary cutting unit (230a) and the second rotary cutting unit (230b) rotate through the interlocking unit (400), and the cut material transport unit (300) operates together. The first rotary cutting unit (230a) and the second rotary cutting unit (230b) cut the fish using cutting blades (231) that cross each other, and the cut material guide unit (240) guides the cut fish to the lower cut material transport unit (300). The fish that has moved to the cut material transport unit (300) is transported along the transport belt (320) to the fish discharge port (130) and discharged to the outside of the main body (100).

[0056] In this way, the cutting of the fish and the transport of the cut fish can be performed together simply by the user rotating the control unit (500) without using a separate motor.

[0057] After use is finished, the cutting guide (240) can be separated upward, or the connection between the cutting unit (200) and the main body (100) and the interlocking part (400) can be released, and the cutting unit (200) can be withdrawn to the side of the main body (100) to be separated.
