Description

Technical Field

[0001] This invention relates to the technical field of aquatic fish transport, and more particularly to a method for transporting aquatic fish and a fish collection bucket. Background Technology

[0002] The structure of a fish collection bucket in a water conservancy facility generally consists of an inlet, a funnel-shaped sieve, and a fish outlet. When the river water flows through the fish collection bucket, fish are swept by the current to the inlet and trapped by the funnel-shaped sieve inside the bucket. Inside the bucket, the fish are trapped and await safe release back into the water, thus achieving the goal of safely transporting fish from upstream to upstream of the water conservancy facility.

[0003] However, the existing methods of concentrating fish inside the fish collection bucket still have problems. For example, not all fish downstream of the water conservancy facility need to migrate upstream. The existing fish collection bucket cannot effectively select fish and cannot collect only those fish that need to reproduce, forage, or migrate for overwintering. Summary of the Invention

[0011] As a preferred embodiment of the water conservancy fish transport method of the present invention, the fish are concentrated by simulating the water flow downstream of the water conservancy facility through a fish collection bucket, thereby attracting fish to the inside of the fish collection bucket.

[0012] As a preferred embodiment of the water conservancy fish transportation method of the present invention, the fish transportation is achieved by lifting the fish collection bucket with a hoisting device and moving the fish collection bucket to the upstream of the water conservancy facility.

[0013] The beneficial effects of the aquatic fish transport method in this invention are as follows: fish are concentrated by simulating a water flow downstream of the water conservancy facility using a fish-collecting bucket, which attracts fish to the inside of the fish-collecting bucket. The purpose of simulating a water flow downstream of the water conservancy facility is to attract fish species with migratory characteristics. These fish will move against the water flow generated by the fish-collecting bucket and enter the inside of the fish-collecting bucket, thus attracting fish with migratory habits to the inside, thereby attracting only fish with migratory needs.

[0017] As a preferred embodiment of the fish-collecting bucket of the present invention, the inclined plate has a first slope, a second slope connected to one end of the first slope, and a vertical surface connected to the other end of the first slope; the end where the first slope and the vertical surface are connected extends inward to the frame, and the end where the first slope and the second slope are connected extends outward to the frame; the slope of the first slope is less than the slope of the second slope.

[0018] In a preferred embodiment of the fish-collecting bucket of the present invention, the buoyancy mechanism includes a mounting frame installed below the inclined plate, and a plurality of buoyancy bladders are installed on the mounting frame.

[0019] As a preferred embodiment of the fish-attracting device of the present invention, it further includes: a fish attractor; the fish attractor includes: a shell, including a pellet chamber, a dispensing port circumferentially distributed on the pellet chamber, an atomizing chamber connected to the pellet chamber, and a group of leaks formed on the atomizing chamber; a flipping mechanism, including a spoon body rotatably mounted on the dispensing port, and a spring-loaded component capable of pushing the spoon body to reset; an intermittent shielding mechanism, including a rotating shaft rotatably mounted on the inner side of the atomizing chamber, and a blocking disc provided on the outer side of the rotating shaft capable of shielding the group of leaks; and a driving mechanism, which is mounted on the inner side of the shell and capable of simultaneously pushing the spoon body to reverse and driving the blocking disc to rotate.

[0035] Example 1

[0036] This embodiment provides a method for transporting fish in aquatic environments, including the following steps:

[0037] S1: Fish are collected downstream of water conservancy facilities using fish-collecting buckets;

[0038] Fish concentration is achieved by creating a simulated water flow downstream of a water conservancy facility using a fish-attracting bucket. This simulated water flow downstream is designed to attract migratory fish species. These fish will move against the current generated by the fish-attracting bucket to enter its inner side, thus preparing to attract migratory fish to its inner side.

[0039] S2: Fish are attracted and retained in the fish collection container using a fish-attracting device;

[0040] By installing a fish-attracting device on the inside of the fish-collecting container, fish can be attracted to the inside of the container, thus preventing fish that have already entered the inside of the container from lingering at the edge and eventually jumping out during continuous current generation.

[0041] S3: The sonar device detects the number of fish inside the fish collecting container and obtains the detection results;

[0042] During the process of simulating water flow to attract fish to the inside of the fish-gathering bucket, a sonar device is installed in the water inside the fish-gathering bucket to conduct sonar detection on the inside of the fish-gathering bucket. The number of fish inside the fish-gathering bucket can be determined based on the detection results.

[0043] S4: Based on the detection results, determine whether to proceed with fish transport.

[0044] Based on the number of fish detected, operators can determine whether to transport the fish collection bucket upstream of the water conservancy facility. Fish transport involves lifting the fish collection bucket using a hoisting device and moving it upstream of the water conservancy facility.

[0045] Example 2

[0046] Reference Figures 1 to 3 This embodiment differs from the first embodiment in that it also proposes a fish-collecting bucket for use in the above-mentioned water conservancy fish transport method. The bucket body 100 includes a frame 101, a bottom plate 102 disposed at the bottom of the frame 101, and a partition net 103 disposed on the side wall of the frame 101; a flow-generating mechanism 200 includes a ramp component 201 disposed on the frame 101, and a water conveying component 202 disposed on the frame 101 capable of conveying water to the ramp component 201; and a buoyancy mechanism 300 disposed on the frame 101.

[0047] The fish tank 100 consists of a frame 101, a bottom plate 102, and a partition net 103, forming a box-like structure with a bottom plate 102, partition nets 103 on all four sides, and an open top. Water is transported to the ramp component 201 through the water conveying component 202 in the flow-generating mechanism 200, so that the water on the ramp component 201 flows down naturally, creating a water flow around the fish tank 100. Fish with migratory habits are attracted by the water flow and swim against the current along the ramp component 201 into the inner side of the fish tank. The buoyancy mechanism 300 can support the entire fish tank to float.

[0048] Specifically, the ramp component 201 includes a bracket 201a and a ramp 201b mounted on the bracket 201a.

[0049] One end of the bracket 201a is fixed to the top of the frame 101, and the other end is used to support the inclined plate 201b, so that the inclined plate 201b can be installed on the top of the frame 101. After the water flows down from the inclined plate 201b, it can generate water flow around the bucket body 100, thereby attracting migratory fish.

[0050] Furthermore, a water inlet 201b-1 is provided on the inclined plate 201b; the water inlet component 202 includes a square tube 202a fixed on the frame 101, and an upper extension tube 202b installed on the square tube 202a; the upper extension tube 202b passes through the water inlet 201b-1.

[0051] A water inlet pipe is connected to the square tube 202a. An external water pump is connected to the water inlet pipe. When the water pump is working, water is sent into the inside of the square tube 202a through the water inlet pipe. The water inside the square tube 202a flows through the upper extension pipe 202b, through the upper surface of the conductive inclined plate 201b-1 of the water delivery hole 201b-1, and then flows down along the upper surface of the inclined plate 201b, generating a water flow.

[0052] Furthermore, the inclined plate 201b has a first slope 202b-2, a second slope 202b-3 connected to one end of the first slope 202b-2, and a vertical surface 202b-4 connected to the other end of the first slope 202b-2; the end where the first slope 202b-2 and the vertical surface 202b-4 are connected extends inward toward the frame 101, and the end where the first slope 202b-2 and the second slope 202b-3 are connected extends outward toward the frame 101; the slope of the first slope 202b-2 is less than the slope of the second slope 202b-3.

[0053] The water inlet 201b-1 is located on the first slope 202b-2. After the water reaches the first slope 202b-2 through the water inlet 201b-1, it will flow to the second slope 202b-3 under the action of gravity. The end of the second slope 202b-3 away from the first slope 202b-2 extends into the water. The water flows into the water on the second slope 202b-3, creating water flow and sound, thereby attracting migratory fish.

[0054] The vertical plane 202b-4 and the partition net 103 are parallel and perpendicular to the water surface, which can prevent fish that have entered the inner side of the container 100 from swimming out.

[0055] Furthermore, the buoyancy mechanism 300 includes a mounting frame 301 installed below the inclined plate 201b, on which a plurality of buoyancy bladders 302 are mounted.

[0056] The mounting frame 301 is located below the inclined plate 201b, and the buoyancy bladder 302 is located on the mounting frame 301. Through the buoyancy of the buoyancy bladder 302, the top of the entire frame 101 and the top of the inclined plate 201b are above the water surface, thus achieving two effects. First, with the top of the inclined plate 201b above the water surface, water can flow down the inclined plate 201b to generate a current. Second, with the top of the frame 101 above the water surface, the problem of fish swimming out of the bucket body 100 from above the frame 101 can be avoided.

[0057] The rest of the structure is the same as in Example 1.

[0058] Example 3

[0059] Reference Figures 4 to 8This embodiment differs from the previous embodiments in that: the fish trap also includes a fish attractor G; in order to concentrate fish within a specific area, it includes a shell 400, a pellet compartment 401, a dispensing port 402 circumferentially distributed on the pellet compartment 401, an atomizing compartment 403 connected to the pellet compartment 401, and a group of leak holes 404 formed on the atomizing compartment 403. The inner side of the pellet compartment 401 is loaded with pellet fish attractants, which can be corn kernels and other natural objects with a width greater than 5 mm, or other commercially available fish attractant pellets. The granular fish attractant on the inner side can fall intermittently through the release port 402 into the water below. The sound of the granules falling into the water attracts fish to the area below the fish attractant device. Meanwhile, the inner side of the atomizing chamber 403 is loaded with powdered fish attractant. When the granules are released through the release port 402, the powdered fish attractant can fall through the perforation group 404 and enter the water, forming a straight atomization band from the water surface to the bottom. This achieves the effect of attracting filter-feeding fish to concentrate below the fish attractant device.

[0060] The fish-attracting device also includes a flipping mechanism 500, which includes a spoon body 501 rotatably mounted on the delivery port 402 and a spring-loaded component 502 capable of pushing the spoon body 501 back to its original position. The spoon mouth 501d of the spoon body 501 faces the inside of the particle chamber 401 in its natural state. The main body of the spoon body 501 can block the delivery port 402 to prevent the particle fish attractant from continuously falling from the delivery port 402. When the spoon body 501 flips, the spring-loaded component 502 stores force. After the spoon body 501 flips, the particle fish attractant inside it is released, allowing the particle fish attractant to enter the water. After the spoon body 501 has finished flipping, it returns to its initial state under the push of the spring-loaded component 502.

[0061] The fish-attracting device also includes an intermittent shielding mechanism 600, which includes a rotating shaft 601 rotatably mounted inside the atomizing chamber 403 and a blocking disc 602 located outside the rotating shaft 601 to shield the leaking hole group 404. In its natural state, the blocking disc 602 in the intermittent shielding mechanism 600 is used to block the leaking hole group 404, so that the powdery fish-attracting substance inside the atomizing chamber 403 cannot fall. When the spoon body 501 flips, the blocking disc 602 and the leaking hole group 404 are misaligned, and the powdery fish-attracting substance falls from the leaking hole group 404 and enters the water.

[0062] The fish attracting device also includes a drive mechanism 700, which is installed inside the housing 400. It can simultaneously drive the spoon body 501 to reverse and drive the blocking plate 602 to rotate. By driving the spoon body 501 and the blocking plate 602 at the same time through the drive mechanism 700, the powdered fish attractant and the granular fish attractant can fall at the same time, thereby attracting filter-feeding fish to concentrate under the fish attracting device and avoiding the problem of fish jumping out from inside the fish collecting hopper.

[0063] Specifically, the inner wall of the dispensing port 402 has a recessed hole 402a, and the outer side of the spoon body 501 is equipped with a protruding post 501a. The protruding post 501a extends to the inner side of the recessed hole 402a and can rotate inside the recessed hole 402a. The spring-loaded member 502 includes a mounting block 502a, which is fixed to the inner wall of the dispensing port 402; an arc post 502b, which is mounted on the mounting block 502a and has the recessed hole 402a as its axis; a first spring 502c, which is sleeved on the outer side of the arc post 502b and abuts against the mounting block 502a; and a snap-fit ​​member 502d, one end of which is fixed to the protruding post 501a, and the other end is snapped onto the outer side of the arc post 502b and abuts against the first spring 502c.

[0064] The drive mechanism 700 can push the spoon body 501. When the spoon body 501 flips, it will drive the locking member 502d to move. The locking member 502d will press the first spring 502c, causing the first spring 502c to deform. When the spoon body 501 is no longer pushed, the elastic force of the first spring 502c pushes the locking member 502d, causing the spoon body 501 to rotate and reset, thereby avoiding the problem of frequent feeding caused by the continuous falling of the fish attractant particles.

[0065] Furthermore, it also includes a pushing mechanism 800; the pushing mechanism 800 includes a slide 801, which is located inside the delivery port 402; a connecting frame 802, which is connected to the slide 801 and extends to the outside of the delivery port 402; an abutment post 803, which is connected to the connecting frame 802 and whose end extends to the inside of the housing 400; a second spring 804, which is sleeved on the outside of the abutment post 803, one end of which abuts against the end of the abutment post 803 located inside the housing 400, and the other end of which abuts against the housing 400; the driving mechanism 700 includes a power member 701 installed inside the housing 400, and a pressing plate 702 connected to the power member 701; the end of the abutment post 803 located inside the housing 400 abuts against the pressing plate 702.

[0066] The power component 701 is a motor, preferably a stepper motor. When the power component 701 is working, it drives the pressing plate 702 to rotate. When the pressing plate 702 rotates, it presses the abutment post 803, causing the abutment post 803 to drive the connecting frame 802 to move, which in turn drives the slide 801 to move. At this time, the slide 801 moves and presses the spoon body 501, pushing the spoon body 501 to flip. During the continuous rotation of the pressing plate 702 driven by the power component 701, the pressing plate 702 no longer presses the abutment post 803. Under the elastic force of the second spring 804, the abutment post 803 moves back to the center of the pressing plate 702, thereby causing the slide 801 to reset. During this process, the first spring 502c pushes the spoon body 501 to flip and reset.

[0067] Furthermore, the outer side of the pressing plate 702 is provided with a squeezing part 702a and a falling part 702b connected to the squeezing part 702a at the position furthest from the center of the pressing plate 702, which abuts against the outer side of the contact post 803 and the pressing plate 702.

[0068] One end of the squeezing part 702a is connected to the pressing plate 702 away from the squeezing part 702, so that the squeezing part 702a has an inclined surface. When the pressing plate 702 rotates, it pushes the abutting post 803, so that the abutting post 803 moves away from the center of the pressing plate 702. One end of the falling part 702b is connected to the end of the squeezing part 702a away from the center of the pressing plate 702, and the other end extends towards the center of the pressing plate 702. When the position of the abutting post 803 corresponds to the position of the falling part 702b, the pressure of the pressing plate 702 on the abutting post 803 disappears instantly. Under the push of the second spring 804, the abutting post 803, the connecting frame 802, and the slide 801 move towards the center of the pressing plate 702, so that the pushing force on the spoon body 501 disappears, so that the spoon body 501 reverses and resets under the push of the first spring 502c.

[0069] Furthermore, a suspension mechanism 900 is provided on the housing 400.

[0070] The device can be installed above the fish-attracting hopper via the suspension mechanism 900. By intermittently dropping granular fish attractants and powdered fish attractants into the water, the device attracts fish and causes them to concentrate below it.

[0071] Furthermore, the delivery port 402 includes a drop trough 402b connecting the external space and the internal space of the particle chamber 401, and a receiving space 402c located below the particle chamber 401; the carriage 801 includes a replacement baffle 801a, which is slidably disposed inside the delivery port 402 and fits against the upper side of the receiving space 402c, and can block the drop trough 402b; a vertical column 801b, which is fixed to the replacement baffle 801a; and a limiting plate 801c, which is connected to the vertical column 801b and fits against the lower side of the receiving space 402c.

[0072] Replacement baffle 801a and limiting plate 801c are respectively attached to the top and bottom of the accommodating space 402c, so that the slide 801 is stably located inside the accommodating space 402c without flipping. The abutment post 803 penetrates the housing 400, so that the slide 801 and the abutment post 803 will not deflect in the horizontal direction, so that the slide 801 can move stably inside the accommodating space 402c.

[0073] When the scoop opening 501d of the scoop body 501 faces the internal space of the pellet chamber 401, the pellet fish attractant inside the pellet chamber 401 enters the scoop opening 501d through the drop trough 402b and enters the inside of the scoop body 501 until the scoop body 501 is full.

[0074] A contact buckle 801d is fixed on the outside of the vertical column 801b. When the slide 801 moves away from the center of the pressing plate 702, the replacement baffle 801a will reach between the spoon opening 501d and the drop trough 402b. When the replacement baffle 801a completely covers the drop trough 402b, the contact buckle 801d will abut and press the spoon body 501, causing the spoon body 501 to rotate. At this time, because the replacement baffle 801a completely covers the drop trough 402b, the problem of the granular fish attractant inside the granular chamber 401 continuously falling from the drop trough 402b can be avoided during the flipping process of the spoon body 501, thereby reducing the frequency of adding granular fish attractant.

[0075] Specifically, a limiting rod 501b is fixed to the outside of the protruding post 501a, and a limiting protrusion 501c is provided on the limiting rod 501b; a limiting groove 402d is opened on the side wall of the dispensing port 402, and the limiting protrusion 501c is slidably engaged with the inside of the limiting groove 402d.

[0076] The limiting groove 402d is an arc-shaped groove with the concave hole 402a as the center, thus cooperating with the limiting rod 501b to drive the guide spoon body 501, so that the spoon body 501 can be flipped around the concave hole 402a as the axis when it is pressed by the contact buckle 801d.

[0077] Furthermore, the inner wall of the dispensing port 402 is provided with a transverse groove 402e that communicates with the concave hole 402a, and the inner wall of the dispensing port 402 is also provided with a forward extension groove 402f that communicates with the limiting groove 402d; the limiting groove 402d is arc-shaped and the limiting groove 402d is centered on the concave hole 402a.

[0078] In this embodiment, after the spoon body 501 completes its initial flip under the push of the contact buckle 801d, the position of the limiting protrusion 501c on the limiting rod 501b corresponds to the position of the forward extension groove 402f, and the position of the protrusion 501a corresponds to the position of the transverse groove 402e. At this time, the contact buckle 801d continues to push the spoon body 501, which enables the spoon body 501 to move away from the center of the pressing plate 702. During the movement, the granular fish attractant continuously falls from the inside of the spoon body 501, thereby increasing the landing range of the granular fish attractant on the water surface and avoiding the problem of the granular fish attractant accumulating together in the water.

[0079] Furthermore, when the contact buckle 801d pushes the spoon body 501, it contacts the limiting rod 501b and presses the limiting rod 501b, so that the spoon body 501 will rotate first before it moves, and then the contact buckle 801d will push the spoon body 501 to move, so that the granular fish attractant inside the spoon body 501 falls down.

[0080] Furthermore, a guide post 402g is fixed inside the transverse groove 402e, and a third spring 402h is sleeved on the outside of the guide post 402g. When the protrusion 501a enters the inside of the transverse groove 402e and moves inside the transverse groove 402e, it will press the third spring 402h, causing the third spring 402h to deform. When the contact buckle 801d no longer presses the limiting rod 501b, the protrusion 501a disengages from the inside of the transverse groove 402e under the push of the third spring 402h, so that the protrusion 501a returns to the inside of the concave hole 402a, and also causes the limiting protrusion 501c to return from the forward extension groove 402f to the limiting groove 402d.

[0081] The protruding post 501a has two symmetrical mating surfaces 501a-1. When the protruding post 501a is located inside the concave hole 402a, the mating surfaces 501a-1 are mated with the inner wall of the concave hole 402a. The two mating surfaces 501a-1 are arc surfaces, and the concave hole 402a is a circular groove. The mating surfaces 501a-1 are designed so that when the protruding post 501a is located inside the concave hole 402a, the mating surfaces 501a-1 can be mated with the inner wall of the concave hole 402a, thereby improving the stability of the protruding post 501a when it rotates inside the concave hole 402a.

[0082] The protruding post 501a also has two symmetrical alignment surfaces 501a-2, which are parallel to each other. When the protruding post 501a is located inside the transverse groove 402e, the alignment surfaces 501a-2 and the groove wall of the transverse groove 402e are in contact. The distance between the two alignment surfaces 501a-2 is matched with the distance between the two inner sidewalls of the transverse groove 402e. The contact buckle 801d pushes the limiting rod 501b, causing the limiting protrusion 5 to... 01c moves inside the limiting groove 402d. When the limiting protrusion 501c reaches the connection point between the limiting groove 402d and the forward extension groove 402f, the two alignment surfaces 501a-2 and the two inner sidewalls of the transverse groove 402e are parallel. At this time, the contact buckle 801d continues to push the limiting rod 501b, and the limiting protrusion 501c can enter the inside of the forward extension groove 402f, and the protrusion 501a can also enter the inside of the transverse groove 402e.

[0083] The protruding post 501a has a through hole 501a-3 on the mating surface 501a-1. When the protruding post 501a is located inside the transverse groove 402e, the guide post 402g passes through the protruding post 501a through the through hole 501a-3.

[0084] When the two aligned surfaces 501a-2 and the two inner walls of the transverse groove 402e are parallel, the through hole 501a-3 will align with the guide post 402g. At this time, the protrusion 501a enters the inner side of the transverse groove 402e, and the guide post 402g will pass through the through hole 501a-3 and penetrate the protrusion 501a. When it moves inside the transverse groove 402e, it also moves outside the guide post 402g, thereby pressing the third spring 402h. When the pushing force of the contact buckle 801d disappears, the elastic force of the third spring 402h pushes the protrusion 501a to move towards the concave hole 402a, thereby disengaging from the transverse groove 402e.

[0085] Therefore, in this embodiment, as the pressing plate 702 rotates, the squeezing part 702a pushes the abutting post 803, causing the abutting post 803 to push the connecting frame 802 and the slide 801 to move away from the center of the pressing plate 702. During this process, the replacement baffle 801a will first reach between the spoon opening 501d and the drop trough 402b, blocking the drop trough 402b before the spoon body 501 flips, thus preventing the problem of the particulate fish attractant continuously falling from the drop trough 402b during the flipping of the spoon body 501.

[0086] Then the contact buckle 801d will contact and push the limit rod 501b. At this time, because the alignment surface 501a-2 and the two inner groove walls of the transverse groove 402e do not correspond, the protrusion 501a cannot enter the transverse groove 402e. At this time, the limit protrusion 501c on the limit rod 501b moves along the limit groove 402d, thereby causing the entire spoon body 501 to flip.

[0087] When the limiting protrusion 501c reaches the connection point between the limiting groove 402d and the forward extension groove 402f, the two alignment surfaces 501a-2 and the two inner sidewalls of the transverse groove 402e are parallel. At this time, the contact buckle 801d continues to push the limiting rod 501b, allowing the limiting protrusion 501c to enter the inner side of the forward extension groove 402f, and the protrusion 501a to enter the inner side of the transverse groove 402e. The limiting protrusion 501c moves along the forward extension groove 402f, and the protrusion 501a moves along the transverse groove 402e, thereby increasing the landing point range of the particle fish attractant on the water surface and avoiding the problem of the particle fish attractant accumulating together in the water.

[0088] Furthermore, the forward extension groove 402f includes a parallel section 402f-1 and an offset section 402f-2. The parallel section 402f-1 is connected to the limiting groove 402d, and the offset section 402f-2 is connected to the parallel section 402f-1. The end of the offset section 402f-2 away from the parallel section 402f-1 is offset towards the transverse groove 402e. The outer side of the guide post 402g is provided with a concave section 402g-1.

[0089] To ensure that the granular fish attractant inside the spoon body 501 falls relatively evenly during the movement of the spoon body 501, when the limiting protrusion 501c moves to the position corresponding to the forward extension groove 402f in the limiting groove 402d, the entire spoon body 501 does not immediately and completely flip over. Instead, it first flips over at a certain angle, which is less than 90 degrees, so that the granular fish attractant inside the spoon body 501 does not all fall over during the flipping process. Then, the limiting protrusion 501c moves inside the forward extension groove 402f, and the protrusion 5... 01a is sleeved on the outside of the guide post 402g and moves on the outside of the guide post 402g. When the limiting protrusion 501c reaches the offset section 402f-2, the protrusion 501a will also reach the concave section 402g-1. At this time, with the offset of the limiting protrusion 501c, the position of the protrusion 501a on the outside of the guide post 402g concave section 402g-1 will also send a small amplitude of continued deflection, so that the flipping angle of the spoon body 501 continues to increase, thereby scattering the granular fish attractant remaining on the inside of the spoon body 501.

[0090] Of course, in order to allow the protruding post 501a to rotate slightly at the position of the concave section 402g-1 on the outer side of the guide post 402g, the distance between the two inner sidewalls at the corresponding positions of the transverse groove 402e and the concave section 402g-1 is increased, thereby facilitating the flipping of the protruding post 501a.

[0091] In order for the protruding post 501a to return to the inside of the concave hole 402a, and for the limiting protrusion 501c to return to the inside of the limiting groove 402d, the spoon body 501 can automatically flip. The locking member 502d has an elongated groove. Before the spoon body 501 flips or moves, the arc post 502b is located at the end of the elongated groove furthest from the opening. During the movement of the spoon body 501, the elongated groove prevents the locking member 502d from disengaging from the outside of the arc post 502b, thus ensuring the spoon body 501 moves smoothly. The snap-fit ​​component 502d remains in the state of pressing the first spring 502c. When the protrusion 501a returns to the inside of the concave hole 402a and the limiting protrusion 501c returns to the inside of the limiting groove 402d, the thrust of the first spring 502c can push the spoon body 501 to flip and reset. Then the replacement baffle 801a is removed from the drop groove 402b and returned to the accommodating space 402c. The fish attractant particles inside the particle chamber 401 can fall into the inside of the spoon body 501 again until the spoon body 501 flips again.
