Description

Technical Field

[0001] The present invention relates to the technical field of rice-loach co-cultivation, and in particular to a rice-loach co-cultivation breeding system. Background Art

[0002] Modern aquaculture practices increasingly prioritize the rational use of resources. Cultivating fish, shrimp, and turtles alongside rice cultivation maximizes resource utilization and aligns with the ecological philosophy of symbiosis and co-breeding. Loach, with its strong disease resistance and rapid reproduction, is a prime candidate for rice paddy farming. While rice-loach co-cultivation technology has been widely adopted, in practice, loach often escape with the current during heavy rains. Therefore, we propose a rice-loach co-cultivation system. Summary of the Invention

[0003] In order to solve the technical problems raised in the background technology, the present invention provides a rice-loach co-cultivation and breeding system.

[0004] The present invention is implemented by the following technical solution: a rice-loach co-cultivation and breeding system, including an escape prevention device, which is inserted at the four sides of the rice field. The escape prevention device includes a blocking mechanism, a baffle and a base, the baffle is installed on the base, and the blocking mechanism is installed on the top of the baffle.

[0005] The enclosure mechanism includes a control component and a blocking component. The control component is rotatably installed above the baffle side, and the power output end of the control component is rotatably connected to the blocking component to control the opening and closing of the blocking component to enclose the range surrounded by the baffle to prevent loaches from escaping.

[0006] The base is installed at the bottom of the rice field and is deeply embedded in the soil of the rice field to prevent loaches from escaping from the mud bottom.

[0007] Through the above technical solution, the device is installed on the four sides of the rice field, and the base is inserted 30 cm deep into the soil to prevent loaches from escaping by digging holes in the soil. Then the control component installed above the baffle controls the rotation of the rotatably connected blocking component to open the blocking component and increase the height of the baffle to prevent the water level from rising during heavy rain, causing the loaches to escape from the top of the baffle with the water.

[0008] As a further improvement of the above scheme, the control component includes a float, a connecting rod 1 and a connecting rod 2. The float is floated on the water surface of the rice field. The float is connected to one end of the connecting rod 1. A mounting rod is provided above the baffle side. The other end of the connecting rod 1 is rotatably connected to the mounting rod. The mounting rod is also rotatably connected to the connecting rod 2. The connecting rod 2 is fixedly connected to the connecting rod 1. The end of the connecting rod 2 away from the connecting rod 1 is rotatably connected to the blocking component to drive the blocking component to move.

[0009] Through the above technical solution, when the water level in the rice field rises due to heavy rain, the water in the rice field will first contact the float, and the float will float due to the rising water level, so that the connecting rod 1 connected to the float will rotate around the mounting rod installed on the baffle. Since the connecting rod 2 is fixedly connected to the connecting rod 1, when the connecting rod 1 rotates around the mounting rod, it also drives the connected connecting rod 2 to rotate around the mounting rod. The rotation of the connecting rod 2 drives the blocking assembly to unfold on the top of the baffle, preventing loaches from escaping from the top of the baffle.

[0010] As a further improvement of the above scheme, the blocking assembly includes a vertical blocking unit, which includes a connecting rod four, a sliding plate, a slider and a fishing net one. The end of the connecting rod two away from the connecting rod one is rotatably connected to the sliding plate, and the sliding plate is slidably set on a fixed plate. The fixed plate is provided with a sliding groove for the sliding plate to slide, and the end of the fixed plate away from the sliding plate is connected to a fixed rod, which is fixedly installed on the top of the baffle, and the end of the sliding plate away from the connecting rod two is rotatably connected to the connecting rod four, and the slider is rotatably installed on the end of the connecting rod four away from the sliding plate, and the slider is slidably set on a slide rod one, which is fixedly installed on the fixed rod, and the slide rod one is vertically set, and the end of the slider away from the connecting rod four is detachably connected to the fishing net one, and a storage unit one is provided on the fixed rod, and the end of the fishing net one away from the slider is fixedly connected to the storage unit one, and the connecting rod four pushes the slider to slide on the slide rod to longitudinally unfold the fishing net one.

[0011] Through the above technical solution, when the connecting rod 2 rotates around the rotating connection with the mounting rod, the sliding plate connected to the other end of the connecting rod 2 rotates in the fixed plate, causing the other end of the connecting rod 4 connected to the other end of the sliding plate to slide along the sliding rod 1. The end of the connecting rod 4 away from the sliding plate is connected to the fishing net 1. The fishing net 1 is vertically arranged, and the bottom end of the fishing net is fixed in the storage unit 1, so the other end is driven by the slider on the connecting rod 4 to unfold along the vertically arranged sliding rod 1, thereby increasing the overall height and preventing loaches from escaping from the top of the baffle when the water level in the rice field rises.

[0012] As a further improvement of the above scheme, the blocking assembly also includes a transverse blocking unit, which includes a connecting rod five, a sliding rod two, a sliding block and a fishing net two. One end of the connecting rod five is rotatably connected to the end of the sliding plate away from the connecting rod two, and the other end is rotatably connected to the sliding block. The sliding block is slidably set on the sliding rod two, and the sliding rod two is fixedly set on the top of the baffle. The sliding rod two is horizontally set, and the sliding block is detachably connected to one end of the fishing net two. The end of the sliding rod two away from the baffle is installed with a storage unit two, and the end of the fishing net two away from the sliding block is fixedly connected to the storage unit two. The connecting rod five pushes the sliding block to slide along the sliding rod two to horizontally unfold the fishing net two.

[0013] Through the above technical solution, since there is a certain distance between the fishing net 1 and the baffle in the horizontal direction, in order to prevent loaches from escaping from the space between the baffle and the fishing net 1, a horizontal blocking unit is also provided. When the sliding plate slides in the fixed plate, the end of the sliding plate away from the connecting rod 2 is also rotated and connected to the connecting rod 5, and the sliding block rotatably connected to the other end of the connecting rod 5 is driven to unfold the fishing net 2 installed on the sliding block. Since the other end of the fishing net 2 is also fixedly installed on the storage unit 2 like the fishing net 1, the fishing net 2 is driven by the sliding block to unfold along the horizontally arranged slide rod 2, filling the gap between the fishing net 1 and the baffle, thereby preventing loaches from escaping from here.

[0014] As a further improvement of the above scheme, a water inlet and a water outlet are also provided at the bottom of the baffle. The water inlet is provided with a water inlet pipe and a blocking assembly. The water inlet pipe is connected to the water inlet. The blocking assembly is installed at the end of the water inlet away from the water inlet pipe to open and close the water inlet. A cap is blocked in the water outlet.

[0015] Through the above technical solution, when water needs to be added to the rice field, water is added to the rice field through the water inlet. The water inlet is opened on the baffle. The water inlet at one end of the baffle away from the rice field is connected to the water pipe, and the other end is connected to the blocking component. The blocking component can allow water to flow into the rice field when water is entering, and block the water inlet when the water inlet stops, so as to prevent loaches from escaping from the water inlet when no water is entering.

[0016] As a further improvement of the above scheme, the blocking assembly includes a fixed ring, a spring and a blocking cover. The water inlet pipe is coaxially installed at one end outside the water inlet, and the fixed ring is coaxially fixedly installed on the outside of the end of the water inlet away from the water inlet pipe. A spring is installed at the other end of the fixed ring, and the end of the spring away from the fixed ring is connected to the blocking cover. A movable cover is also coaxially installed inside the blocking cover, and the movable cover matches the water inlet.

[0017] With the above technical solution, when water enters, it flows toward the area surrounded by the baffle. At this time, the water flow will dislodge the movable cover that blocks the water inlet. Since the movable cover is mounted on the blocking cover and is connected to a fixing ring mounted on the baffle via a spring, when the water flow dislodges the movable cover, the spring expands, allowing the blocking cover to carry the movable cover away from the area blocking the water inlet, thereby allowing the water to flow smoothly into the area surrounded by the baffle. After the water flow stops, the spring will not expand because it is not impacted by the water flow. At this time, the spring in its normal state will carry the movable cover connected to the blocking cover to block the water inlet, sealing the water inlet and preventing loaches from escaping.

[0018] As a further improvement of the above scheme, the base includes a supporting diagonal rod 1, a supporting diagonal rod 2 and an insertion rod. The insertion rod is vertically installed at the bottom of the baffle. The supporting diagonal rod 1 and the supporting diagonal rod 2 are both installed at an angle at the bottom of the baffle and are installed in a V shape on both sides of the insertion rod.

[0019] Through the above technical solution, the supporting diagonal rods 1 and 2 can fix the baffle after it is inserted into the soil, so as to prevent the baffle from swinging left and right. The insertion rods can better assist the baffle in being inserted into the soil.

[0020] As a further improvement of the above scheme, storage unit 1 includes a storage cylinder and a winding roller. The winding roller is coaxially installed in the storage box. Fishing net 1 is wrapped around the outside of the winding roller and stored in the storage box. The storage box has a net outlet slot. The end of the fishing net 1 away from the winding roller passes through the net outlet slot and is detachably connected to the slider. Storage unit 1 has the same structure as storage unit 2.

[0021] Through the above technical solution, the fixed end of the fishing net 1 is stored in the storage tube, and the fishing net 1 is stored around the winding roller. A net outlet slot is opened on the outside of the storage box, and the fishing net 1 passes through the storage box through the net outlet slot. When the fishing net 1 is damaged, the damaged fishing net 1 can be cut off in time, so that the new fishing net 1 can be unfolded to cover the top of the baffle.

[0022] As a further improvement of the above solution, a torsion spring is coaxially arranged on the winding roller so that when the fishing net is tightened, the winding roller is reversed to wind the fishing net back to the outside of the winding roller.

[0023] Through the above technical solution, after the water level drops, the torsion spring on the winding roller will reverse and retract the fishing net, avoiding the pulled out fishing net hanging outside the storage tube after the water level drops and causing damage, thereby reducing the service life.

[0024] As a further improvement of the above solution, the bottom of the insertion rod is in an inverted cone shape, so that the insertion rod can be better inserted into the soil.

[0025] Through the above technical solution, the bottom of the insertion rod is pointed, which makes it easier to be inserted into the soil.

[0026] Compared with the existing technology, the beneficial effect of the present invention is that the device is installed on the four sides of the rice field, and the base is inserted into the soil at a depth of 30 cm to prevent loaches from burrowing through the soil to escape. Then, the control component installed above the baffle controls the rotation of the rotatably connected blocking component to open the blocking component, which increases the height of the baffle. This prevents the water level from rising during heavy rain, causing loaches to escape from the top of the baffle. By setting up the blocking component, loaches can be prevented from escaping from the top of the baffle with the water when the water level in the rice field rises during heavy rain. A blocking component is also provided to ensure that water flows into the rice field when water is inflowing, and to block the water inlet when water inflow stops to prevent loaches from escaping from the water inlet.

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0035] Example 1:

[0036] Please combine Figure 1 The rice-loach co-cultivation system of this embodiment includes an escape prevention device inserted at the four edges of the rice field. The escape prevention device comprises an enclosure mechanism 1, a baffle 2, and a base 3. The baffle 2 is mounted on the base 3, and the height of the baffle 2 is greater than the water level in the rice field. The enclosure mechanism 1 is mounted on the top of the baffle 2, and the baffle 2 is installed at the four edges of the rice field. The enclosure mechanism 1 and base 3 are respectively provided at the two ends of the baffle 2 in the longitudinal direction.

[0037] The enclosure mechanism 1 includes a control component 101 and a blocking component 102. The control component 101 is rotatably installed on the upper side of the baffle 2. The power output end of the control component 101 is rotatably connected to the blocking component 102 to control the opening and closing of the blocking component 102 to enclose the range surrounded by the baffle 2 to prevent loaches from escaping.

[0038] The base 3 is installed at the bottom of the paddy field, and the base 3 is deeply embedded in the paddy field soil to prevent loaches from escaping from the mud bottom.

[0039] The device is installed on the four sides of the rice field, and the base 3 is inserted into the soil to a depth of 30 cm to prevent loaches from escaping by digging holes in the soil. Then the control component 101 installed above the baffle 2 controls the rotation of the rotatably connected blocking component 102 to open the blocking component 102, thereby increasing the height of the baffle 2 to prevent the water level from rising during heavy rain, causing the loaches to escape from the top of the baffle 2 with the water.

[0040] Please combine Figure 1 The control assembly 101 includes a float 4, a connecting rod 1 5, and a connecting rod 2 6. The float 4 floats on the surface of the paddy field and is connected to one end of the connecting rod 1 5. The two connecting rods are detachably connected, allowing them to be replaced with other items when the float 4 lacks sufficient buoyancy. A mounting rod 7 is located above the baffle 2. The other end of the connecting rod 1 5 is rotatably connected to the mounting rod 7. The mounting rod 7 is also rotatably connected to the connecting rod 2 6. The connecting rod 2 6 is fixedly connected to the connecting rod 1 5. The end of the connecting rod 2 6, away from the connecting rod 1 5, is rotatably connected to the blocking assembly 102 to drive the blocking assembly 102 to move.

[0041] When the water level in the rice field rises due to heavy rain, the water in the rice field will first contact the float 4, and the float 4 will float due to the rising water level, so that the connecting rod 1 5 connected to the float 4 will rotate around the mounting rod 7 installed on the baffle 2. Since the connecting rod 2 6 is fixedly connected to the connecting rod 1 5, when the connecting rod 1 5 rotates around the mounting rod 7, the connected connecting rod 2 6 is also driven to rotate around the mounting rod 7. The rotation of the connecting rod 2 6 drives the blocking assembly 102 to unfold at the top of the baffle 2, preventing loaches from escaping from the top of the baffle 2.

[0042] Please combine Figure 2 as well as Figure 3The blocking assembly 102 includes a vertical blocking unit 8, which includes a connecting rod 4 81, a sliding plate 82, a slider 83 and a fishing net 1 84. The end of the connecting rod 2 6 away from the connecting rod 1 5 is rotatably connected to the sliding plate 82. The sliding plate 82 is slidably arranged on a fixed plate 85. The fixed plate 85 is provided with a sliding groove for the sliding plate 82 to slide. The width of the sliding groove is the same as the diameter of the sliding plate 82. The end of the fixed plate 85 away from the sliding plate 82 is connected to a fixed rod 86, which is fixedly installed on the top of the baffle 2. The end of the sliding plate 82 away from the connecting rod 2 6 is rotatably connected to the connecting rod 4 8 1. The slider 83 is rotatably mounted on the end of the connecting rod 4 81 away from the sliding plate 82. The slider 83 is slidably mounted on a sliding rod 1 87. The sliding rod 1 87 is fixedly mounted on the fixed rod 86. The sliding rod 1 87 is vertically arranged. The end of the slider 83 away from the connecting rod 4 81 is detachably connected to the fishing net 1 84. The length of the fishing net 1 84 is equal to the length of the baffle 2. A storage unit 1 88 is provided on the fixed rod 86. The end of the fishing net 1 84 away from the slider 83 is fixedly connected to the storage unit 1 88. The connecting rod 4 81 pushes the slider 83 to slide on the slide rod to longitudinally unfold the fishing net 1 84.

[0043] When the connecting rod 2 6 rotates around the rotating connection with the mounting rod 7, the sliding plate 82 connected to the other end of the connecting rod 2 6 rotates in the fixed plate 85, causing the other end of the connecting rod 4 81 connected to the other end of the sliding plate 82 to slide along the sliding rod 1 87. The end of the connecting rod 4 81 away from the sliding plate 82 is connected to the fishing net 1 84. The fishing net 1 84 is vertically arranged, and the bottom end of the fishing net is fixed in the storage unit 1 88, so the other end is driven by the slider 84 on the connecting rod 4 81 to unfold along the vertically arranged sliding rod 1 87, thereby increasing the overall height and preventing loaches from escaping from the top of the baffle 2 when the water level in the rice field rises.

[0044] Please combine Figure 1 as well as Figure 4 A water inlet 10 and a water outlet 11 are also provided at the bottom of the baffle 2. The water inlet 10 is provided with a water inlet pipe 12 and a blocking component 13. The water inlet pipe 12 is connected to the water inlet 10, and the other end of the water inlet pipe 12 is connected to an external water delivery device. The blocking component 13 is installed at the end of the water inlet 10 away from the water inlet pipe 12 to open and close the water inlet 10. A cap is blocked in the water outlet 11, and the diameter of the cap matches the diameter of the water outlet 11.

[0045] When water needs to be added to the rice field, water is added to the rice field through the water inlet 10. The water inlet 10 is opened on the baffle 2. The water inlet 10 at one end of the baffle 2 away from the rice field is connected to the water pipe, and the other end is connected to the blocking component 13. The blocking component 13 can allow water to flow into the rice field when water is entering, and block the water inlet 10 when the water inlet stops, so as to prevent loaches from escaping from the water inlet 10 when no water is entering.

[0046] Please combine Figure 4The blocking assembly 13 includes a fixing ring 14, a spring 15 and a blocking cover 16. The water inlet pipe 12 is coaxially installed at one end outside the water inlet 10. The fixing ring 14 is coaxially fixedly installed on the outside of the end of the water inlet 10 away from the water inlet pipe 12. A spring 15 is installed at the other end of the fixing ring 14. The end of the spring 15 away from the fixing ring 14 is connected to the blocking cover 16. A movable cover 17 is also coaxially installed in the blocking cover 16. The movable cover 17 matches the water inlet 10. The length of the spring 15 in the normal state is less than the horizontal length of the blocking cover 16, so that when no water is entering, a part of the movable cover 17 is plugged in the water inlet 10.

[0047] When water enters, water flows into the position surrounded by the baffle 2. At this time, the water flow will break open the movable cover 17 that blocks the water inlet. Since the movable cover 17 is installed on the blocking cover 16, and the blocking cover 16 is connected to the fixing ring 14 installed on the baffle 2 through the spring 15, when the water flow breaks open the movable cover 17, the spring 15 expands, so that the blocking cover 16 and the movable cover 17 leave the position blocking the water inlet 10, so that the water flow can smoothly enter the range surrounded by the baffle 2. After the water inflow is completed, the spring 15 will not extend because it is not impacted by the water flow. At this time, the spring 15 in the normal state will bring the movable cover 17 on the connected blocking cover 16 to block the water inlet 10, so that the water inlet 10 is closed and prevent loaches from escaping.

[0048] Please combine Figure 1 The base 3 includes a first diagonal support rod 31, a second diagonal support rod 32, and an insertion rod 33. The insertion rod 33 is vertically mounted on the bottom of the baffle 2. The first diagonal support rod 31 and the second diagonal support rod 32 are both tilted and mounted on the bottom of the baffle 2. The lengths of the first diagonal support rod 31 and the second diagonal support rod 32 are greater than the length of the insertion rod 33, and the lengths of the first diagonal support rod 31 and the second diagonal support rod 32 are equal. They are mounted in a V-shape on both sides of the insertion rod 33.

[0049] The first supporting diagonal rod 31 and the second supporting diagonal rod 32 can fix the baffle 2 after the baffle 2 is inserted into the soil, so as to prevent the baffle 2 from swinging left and right. The insertion rod 33 can better assist the baffle 2 in being inserted into the soil.

[0050] Please combine Figure 5 The storage unit 88 includes a storage cylinder 18 and a winding roller 19. The winding roller 19 is coaxially installed in the storage box. The length of the winding roller 19 is equal to the length of the storage cylinder 18, and the length of the storage cylinder 18 is equal to the length of the fishing net 84. The fishing net 84 is wrapped around the outside of the winding roller 19 and stored in the storage box. The storage box is provided with a net outlet slot. The end of the fishing net 84 away from the winding roller 19 passes through the net outlet slot and is detachably connected to the slider 83. The storage unit 1 88 has the same structure as the storage unit 2 95.

[0051] One end of the fishing net 84 is stored in the storage tube 18, and the fishing net 84 is stored around the winding roller 19. A net outlet slot is opened on the outside of the storage box, and the fishing net 84 passes through the storage box through the net outlet slot. When the fishing net 84 is damaged, the damaged fishing net 84 can be cut off in time to allow a new fishing net 84 to be unfolded to cover the top of the baffle 2.

[0052] Please combine Figure 5 A torsion spring 15 is coaxially arranged on the winding roller 19. The diameter of the torsion spring 15 is smaller than the diameter of the storage cylinder 18, so that when the fishing net 84 is gathered, the winding roller 19 is reversed to make the fishing net 84 wind back to the outside of the winding roller 19.

[0053] After the water level drops, the torsion spring 15 on the winding roller 19 will reverse the fishing net 84 and recycle it back to avoid the pulled-out fishing net 84 hanging outside the storage tube 18 after the water level drops, causing damage and reducing the service life.

[0054] Please combine Figure 1 The bottom of the insertion rod 33 is in an inverted cone shape. Two insertion rods 33 are provided and are respectively provided on both sides of the length direction of the baffle 2 so that the insertion rods 33 can be better inserted into the soil.

[0055] The bottom of the insertion rod 33 is pointed, making it easier to be inserted into the soil.

[0056] Example 2:

[0057] Combine Figure 2 as well as Figure 3 The present embodiment is a further improvement on the basis of the embodiment 1 in that the blocking assembly 102 further includes a transverse blocking unit 9, which includes a connecting rod 5 91, a sliding rod 2 92, a sliding block 93 and a fishing net 2 94. One end of the connecting rod 5 91 is rotatably connected to the end of the sliding plate 82 away from the connecting rod 2 6, and the other end is rotatably connected to the sliding block 93. The sliding block 93 is slidably arranged on the sliding rod 2 92, and the sliding rod 2 92 is fixedly arranged at the top of the baffle 2. The sliding rod 2 92 is horizontally arranged, and the sliding block 93 is detachably connected to one end of the fishing net 2 94. The end of the sliding rod 2 92 away from the baffle 2 is installed with a storage unit 2 95, and the end of the fishing net 2 94 away from the sliding block 93 is fixedly connected in the storage unit 2 95. The connecting rod 5 91 pushes the sliding block 93 to slide along the sliding rod 2 92 to horizontally unfold the fishing net 2 94. The length of the fishing net 2 94 is equal to the length of the fishing net 1 84, and the distance by which the fishing net 2 94 is stretched is greater than or equal to the horizontal distance between the fishing net 1 84 and the baffle 2.

[0058] Since there is a certain distance between the fishing net 1 84 and the baffle 2 in the horizontal direction, in order to prevent loaches from escaping from the space between the baffle 2 and the fishing net 1 84, a transverse blocking unit 9 is also provided. When the sliding plate 82 slides in the fixed plate 85, the end of the sliding plate 82 away from the connecting rod 2 6 is also rotatably connected to the connecting rod 5 91, and the sliding block 93 rotatably connected to the other end of the connecting rod 5 91 is driven to unfold the fishing net 2 94 installed on the sliding block 93. Since the other end of the fishing net 2 94 is also fixedly installed on the storage unit 2 95 like the fishing net 1 84, the fishing net 2 94 is driven by the sliding block 93 to unfold along the horizontally arranged slide rod 2 92, filling the gap between the fishing net 1 84 and the baffle 2, and preventing loaches from escaping from here.

[0059] The implementation principle of a rice-loach co-cultivation system is as follows: insert the base 3 into the soil at the edge of the rice field, and insert a corresponding number of the devices according to the side length of the rice field until the baffle 2 completely surrounds the rice field. When there is no heavy rain, the baffle 2 is higher than the water level in the rice field, so the baffle 2 can have a barrier effect on the loaches in the rice field to prevent the loaches from escaping. When it rains heavily, the water level in the rice field becomes higher, and the float 4 set on the water surface will float up, generating an upward force to make the connecting rod 1 5 connected to the float 4 rotate around the mounting rod 7. Since the connecting rod 1 5 is fixedly connected to the connecting rod 2 6, when the connecting rod 1 5 rotates, it will bring the connected connecting rod 2 6 to rotate around the mounting rod 7, so that the sliding plate 82 connected to the other end of the connecting rod 2 6 will slide up in the sliding groove provided on the fixed plate 85. Since the rotation of the connecting rod 2 6 around the mounting rod 7 produces a sliding around the center of the circle, The sliding at the connection between the connecting rod 2 6 and the sliding plate 82 is a circular sliding, that is, a horizontal force and a vertical force are generated at the same time. The forces in these two directions generated by the sliding plate 82 drive the slider 83 connected to the other end of the connecting rod 4 81 rotatably connected to the sliding plate 82 to slide up along the vertically arranged slide rod 1 87. The slider 83 is detachably connected to the fishing net 1 84, and the other end of the fishing net 1 84 is fixed in the storage tube 18. As a result, the fishing net 1 84 is unfolded upward, making the height of the entire device higher, thereby preventing loaches from escaping from above the baffle 2 when the water level in the rice field rises. At the same time, the horizontal force generated by the sliding of the sliding plate 82 in the chute causes the fishing net 2 94 to be horizontally unfolded along the slide rod. The position where the fishing net 2 94 is unfolded is exactly the position where a gap is generated between the fishing net 1 84 and the baffle 2, which can prevent loaches from escaping from this gap when the fishing net 1 84 is unfolded. At the same time, when the water inlet pipe 12 is supplying water to the rice field, the water flow of the water inlet pipe 12 will block the movable cover 17 of the water inlet 10 and rush out, so that the water flow can flow smoothly into the rice field. When water is not supplied, the water flow stops impacting the movable cover 17, and the spring 15 returns to its initial state, driving the movable cover 17 to block the water inlet 10 to prevent loaches from escaping from the water inlet 10. The insertion rod 33 provided on the base 3 is convenient for insertion into the bottom of the rice field, and the supporting inclined rod 1 31 and the supporting inclined rod 2 32 can prevent the baffle 2 from shaking.

[0060] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
