[0033] The utility model will be described in detail below with reference to the drawings and in combination with embodiments.
[0034] A rice field ring ditch green shrimp breeding device, which can be constructed by Figures 1-7 is schematically shown. In the present embodiment, the rice field ring ditch green shrimp breeding device comprises a shrimp nest 1, an anchoring assembly and a gas supply assembly, wherein the shrimp nest 1 is used for providing a habitat for green shrimps, the anchoring assembly is used for fixing the shrimp nest 1 at the bottom of the ring ditch to avoid abnormal movement of the shrimp nest, and the gas supply assembly is used for delivering oxygen to the shrimp nest 1 to facilitate oxygen pumping and aeration during the green shrimp breeding process.
[0035] Specifically, the shrimp nest 1 is provided with a gas supply channel 11 and a plurality of habitat channels, wherein the length direction of the gas supply channel 11 is parallel to the length direction of the shrimp nest 1, the plurality of habitat channels are arranged along the length direction of the shrimp nest 1, and the length direction of each habitat channel is perpendicular to the length direction of the shrimp nest 1. The side wall of the shrimp nest 1 provided with the gas supply channel 11 is further provided with a gas guide hole 13, and the gas guide hole 13 is in communication with the habitat channel. In use, the habitat channel in the shrimp nest 1 can provide a habitat for the juvenile green shrimps to obtain a stable and reliable living environment in the water bottom area, and the gas supply channel 11 cooperates with the gas supply assembly to guide the oxygen delivered by the external oxygen pump device into the water body, thereby increasing the oxygen content of the water body near the shrimp nest 1, and the gas guide hole 13 can guide the oxygen bubbles around the shrimp nest 1 into the habitat channel, thereby increasing the oxygen content in the habitat channel and further improving the living conditions of the juvenile green shrimps in the habitat channel.
[0036] Optionally, as shown in Figure 5 , the habitat channel in the embodiment can include a habitat section 123 and two access sections 121. The two access sections 121 should be respectively arranged on the opposite two side walls of the shrimp nest 1, the habitat section 123 should be arranged inside the shrimp nest 1, and the distance from the habitat section 123 to the top surface of the shrimp nest 1 should be greater than the distance from the access section 121 to the top surface of the shrimp nest 1, and the two access sections 121 should be respectively connected to the two ends of the habitat section 123 through the bending sections 122.
[0037] Because of the height difference between the habitat section 123 and the access section 121, and the access section 121 is connected to the habitat section 123 through the bending section 122, when the water body near the shrimp nest 1 fluctuates due to the movement of the juvenile green shrimps or the oxygen pump aeration, the bending section 122 can effectively buffer the fluctuation of the water body, so as to form a relatively stable water body state inside the habitat section, and ensure that the juvenile green shrimps obtain good living conditions.
[0038] In addition, as shown in Figure 6 , to avoid excessive disturbance of the stability of the inside of the habitat section 123 caused by the bubbles generated by the oxygen pump aeration when entering the habitat channel, the gas guide hole 13 should be connected to the bending section 122, and the ratio of the channel inner diameter of the gas guide hole 13 to the channel inner diameter of the habitat channel should be 1:10. Because the gas guide hole 13 is connected to the bending section 122, it can avoid the bubbles directly entering the inside of the habitat section 123, and because the channel inner diameter of the gas guide hole 13 is much smaller than the channel inner diameter of the habitat channel, it can reduce the volume of the bubbles entering the inside of the habitat channel, thereby reducing the disturbance degree to the inside of the habitat section 123.
[0039] As an optional embodiment of the present embodiment, to avoid the silt at the bottom of the ring ditch from entering the inside of the habitat channel during the oxygen pump aeration process, the paddy field ring ditch juvenile green shrimp breeding device can further include a sand blocking plate 6. Specifically, as shown in Figure 7As shown, in order to realize the assembly of the sand baffle 6, the side wall of the shrimp nest 1 with the access section 121 can be provided with a splicing slot 14, and the splicing slot 14 is located between the access section 121 and the bottom surface of the shrimp nest 1. When assembling, the staff can detachably install one end of the sand baffle 6 in the splicing slot 14, so as to form a shelter below the access section 121, thereby reducing the probability of silt entering the habitat channel.
[0040] In order to facilitate the fixation of the shrimp nest 1 on the bottom of the ring ditch, the anchoring assembly in the embodiment includes two anchoring rods 2. When assembling, the top end of the anchoring rod 2 is hinged to the bottom surface of the shrimp nest 1, and the two anchoring rods 2 should be located at the two ends of the bottom surface of the shrimp nest 1. As shown, Figure 1 As shown, when it is necessary to fix the shrimp nest 1 on the bottom of the ring ditch, the anchoring rod 2 can be driven to rotate about the hinge point, so that the anchoring rod 2 is perpendicular to the bottom surface of the shrimp nest 1, facilitating the insertion of the anchoring rod 2 into the silt on the bottom of the ring ditch. As shown, Figure 4 As shown, when it is necessary to transfer the shrimp nest 1, the staff can also drive the anchoring rod 2 to rotate towards the bottom surface of the shrimp nest 1, thereby reducing the overall space occupation of the device and facilitating the transfer work.
[0041] Optionally, in order to improve the anchoring effect of the anchoring rod 2, the anchoring rod 2 can be provided with a plurality of anchoring notches 21, and the plurality of anchoring notches 21 should be arranged along the length direction of the anchoring rod 2. When the anchoring rod 2 is inserted into the silt, the silt around the anchoring rod 2 will enter the anchoring notches 21, which can increase the difficulty of the anchoring rod 2 to separate from the silt, so that the shrimp nest 1 can be reliably fixed on the bottom of the ring ditch.
[0042] In order to facilitate the delivery of oxygen generated by external oxygen pumping equipment into the gas supply channel 11, the gas supply assembly in the embodiment includes a containing cylinder 3, a cover 4 and a bubble stone inner core 5. The containing cylinder 3 is arranged on the top surface of the shrimp nest 1, and the bottom end of the containing cylinder 3 is in communication with the gas supply channel 11. The bubble stone inner core 5 is detachably arranged in the containing cylinder 3, the cover 4 is detachably arranged on the top of the containing cylinder 3, and the cover 4 is provided with an air inlet pipe 41.
[0043] When in use, the staff can connect the air inlet pipe 41 to the air outlet of the oxygen pumping equipment (the air pipe and the oxygen pumping equipment are not shown in the drawings of the present application) through the channel guide pipe, so that the oxygen generated by the oxygen pumping equipment enters the containing cylinder 3. Since the shrimp nest 1 needs to be anchored on the water bottom when in use, the gas supply assembly on the top surface of the shrimp nest 1 is also completely immersed in water. When the oxygen enters the containing cylinder 3, the bubble stone inner core 5 soaked in water will divide the oxygen into small bubbles, and these bubbles will leave the shrimp nest 11 along the gas supply channel 11, thereby increasing the oxygen content of the water near the shrimp nest 11.
[0044] Optionally, in order to ensure that the bubble stone inner core 5 fully plays a role, the inner wall of the containing cylinder 3 can be provided with a limiting ring 31 with an inner diameter smaller than the outer diameter of the bubble stone inner core 5, and the outer diameter of the bubble stone inner core 5 should be equal to the inner diameter of the containing cylinder 3, so that the oxygen entering the inside of the containing cylinder 3 must first pass through the bubble stone inner core 5 to enter the inside of the air supply channel 11.
[0045] In addition, in order to improve the probability of bubbles entering the air guide hole 13, the shrimp nest 1 of the embodiment can also be provided with a gas blocking plate 7 on the side wall of the air guide hole 13. As shown in Figure 5 The gas blocking plate 7 should be located above the air supply channel 11, the air guide hole 13 should be located below the air supply channel 11, and an arc-shaped air guide plate 71 with an arc center facing the air guide hole 13 should also be provided at the end of the gas blocking plate 7 away from the shrimp nest 1. When the bubbles leave the air supply channel 11, the bubbles will float upward under the action of the buoyancy, at which time the gas blocking plate 7 will block the bubbles and slow down the upward floating speed of the bubbles, providing sufficient time for the bubbles to enter the air guide hole 13. At the same time, the presence of the arc-shaped air guide plate 71 can also guide the movement path of the bubbles, so that the bubbles are more easily guided into the air guide hole 13.
[0046] As another optional embodiment of the embodiment, in order to improve the effect of breeding rice field green shrimps in the ring ditch, the rice field ring ditch green shrimp breeding device also includes a water plant carrying assembly, so that the staff can cultivate water plants (such as water lotus or cabomba) through the water plant carrying assembly, thereby purifying the water in the ring ditch with the help of the water plants.
[0047] Specifically, the water plant carrying assembly can include a connecting ring 81, a pulling rope 82 and a floating plate 83, wherein the connecting ring 81 is detachably provided on the top surface of the shrimp nest 1 through a threaded joint, the floating plate 83 is provided above the shrimp nest 1, and the bottom surface of the floating plate 83 is connected to the connecting ring 81 through the pulling rope 82. The floating plate 83 should also be provided with a plurality of containing holes 831, and each containing hole 831 can be provided with a planting basket 9 inside, so as to accommodate and fix the root system of the water plants through the planting basket 9.
[0048] Since the bottom surface of the shrimp nest 1 is provided with the anchoring assembly, when the water plants are cultivated through the water plant carrying assembly, the anchoring assembly can also pull the water plant carrying assembly, thereby avoiding the water plant carrying assembly from abnormally drifting away.
[0049] The effects of the above-mentioned scheme are described as follows:
[0050] The embodiment provides a rice field ring ditch green shrimp breeding device, which can provide a stable living environment for green shrimps through the inhabiting channel, and can transport oxygen to the vicinity of the shrimp nest through the air supply assembly and the air supply channel, so that the oxygen content near the shrimp nest is improved. Secondly, the device can improve the probability of bubbles entering the inhabiting channel through the air guide hole, so as to improve the oxygen content in the inhabiting channel. In addition, the device can also fix the shrimp nest through the anchoring assembly, so as to avoid abnormal movement of the shrimp nest.
[0051] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
