Description

Technical Field

[0001] The utility model relates to the field of oxygenation in rice field aquaculture, in particular to an oxygenation device for fish farming in rice fields. Background Art

[0002] Raising fish on the surface of rice paddies not only produces fish products, but also allows the fish to eat pests and weeds in the paddies, excrete manure, and stir the soil to promote fertilizer decomposition, creating favorable conditions for rice growth and generally increasing rice yields by about 10%. Chinese utility model patent publication number CN214903188U discloses an aeration device for rice paddies. A dual-headed motor drives the rotation of transmission gears and fan blades. The rotation of the fan blades causes water inside the water inlet hood to enter the liquid guide tube under the action of centrifugal force and finally be sprayed out of the nozzle, thereby aerating the water in the paddy field.

[0003] In the above structure, the water in the rice field enters the liquid guide tube under the action of the double-headed motor and is sprayed out through the nozzle above. The position of the nozzle is fixed, and its spraying range is also fixed. The device needs to be placed in the rice field when used, and it is not convenient to change its position at will. That is, it can only spray and oxygenate a smaller range, so that the local oxygen content is higher, while other parts do not change much. Utility Model Content

[0004] In order to solve the technical problem that spraying and oxygenation can only be performed in a small range, resulting in a large local oxygen content and little change in other parts, the utility model provides an oxygenation device for fish farming in rice fields.

The rotating rings provided at both ends of the outer ring of the jet pipe are placed in the annular groove, so that the jet pipe can be quickly rotated and installed on the support frame;

[0007] Fixing holes are provided at both the front and rear ends of the upper surface of the bottom plate. Wooden stakes are passed through the fixing holes and fixed on the ground, so as to fix the bottom plate and thus quickly fix the support seat.

Thereafter, the fixed ring is attached to the surface of the support frame and connected by screws to complete the installation of the support seat and the jet pipe, and it is easy to disassemble and replace.

The extension or retraction of the push rod of the electric push rod can cause the push plate to move accordingly, thereby causing the deflection shaft and the jet pipe to swing accordingly within a certain angle;

[0011] The swing range of the spray pipe is 0-50 degrees. When the spray pipe swings to degrees, the water flow sprayed by the nozzle assembly at this time has the farthest distance, thereby making the overall range wider.

[0012] As a further improvement to the above solution, the end of the jet pipe away from the water outlet pipe is blocked and provided with a connector, and the connector is a hexagonal structure;

[0026] The support seat 5 includes a support frame 51 and a base plate 52. Circular holes are formed on the left and right sides of the support frame 51, and an annular groove is provided on one side of the support frame 51. The annular groove and the cross-section of the circular hole present a boss structure. The rotating rings 61 provided at both ends of the outer ring of the jet tube 6 are placed in the annular groove, so that the jet tube 6 can be quickly rotated and installed on the support frame 51; fixing holes are provided at the front and rear ends of the upper surface of the base plate 52, and wooden stakes are fixed to the ground through the fixing holes, which can fix the base plate 52, thereby quickly fixing the support seat 5.

[0027] A rotating ring 61 is fixed to both left and right ends of the jet pipe 6, and a fixing ring is also slidably sleeved on the jet pipe 6. The fixing ring is connected to the support frame 51 by screws. The end of the jet pipe 6 passes through the circular hole of the support frame 51, and the rotating ring 61 is rotated and placed in the annular groove. After that, the fixing ring is fitted to the surface of the support frame 51 and connected by screws. The installation of the support seat 5 and the jet pipe 6 can be completed, and it is easy to disassemble and replace.

[0028] The nozzle assembly 7 includes a nozzle 1 71 fixed in the middle of the outer surface of the spray tube 6, and a plurality of nozzles 2 72 and nozzles 3 73 are respectively arranged on both sides of the nozzle 1 71 at equal intervals, and the nozzles 2 72 and nozzles 3 73 are respectively tilted toward the left and right sides. The nozzle 1 71, the nozzle 2 72 and the nozzle 3 73 are all connected to the interior of the spray tube 6. The nozzles 2 72 and the nozzles 3 73 are arranged on the left and right sides of the nozzle 1 71 and are tilted.

[0029] The swing mechanism 8 includes an electric push rod 81 mounted above the support seat 5 on one side through a bracket. An L-shaped plate 82 is connected to the push rod of the electric push rod 81. The end of the L-shaped plate 82 away from the push rod is rotatably connected to a push plate 83 via an axle pin, and the other end of the push plate 83 is rotatably connected to a deflection shaft 84 via an axle pin.

[0033] The implementation principle of an oxygenation device for fish farming in rice fields in the embodiment of the present application is as follows: in actual use, a water pump 1 is installed on the bank of a rice field, and then a water inlet pipe 2 is connected to the water inlet of the water pump 1, and the water inlet pipe 2 is placed in the rice field for pumping water, and a jet pipe 6 is installed between two support seats 5, and the tail end of the jet pipe 6 is connected to the deflection shaft 84 in the swing mechanism 8, and then the outlet pipe of the water pump 1 is connected to the front end of the jet pipe 6 through a rotary joint 4, and the two support seats 5 are fixed to the bank by wooden stakes, and then the power supply of the water pump 1 can be turned on, and the water pump 1 will draw water from the rice field through the drain pipe 3 and flow into the jet pipe 6, and the water flow in the jet pipe 6 will flow into the rice field again through the nozzle assembly 7, and the water flow sprayed by the nozzle assembly 7 will increase the contact area with the air, and enter This makes the oxygen content in the sprayed water flow higher, thereby increasing the oxygen content in the rice field water. Since the nozzle assembly 7 includes nozzle 1 71, nozzle 2 72 and nozzle 3 73, and nozzle 2 72 and nozzle 3 73 are arranged on the left and right sides of nozzle 1 71 and are tilted, the sprayed water flow spreads toward both sides, so that the range of the water sprayed by the nozzle assembly 7 is larger. During the spraying process of the nozzle assembly 7, the electric push rod 81 in the swing mechanism 8 will push the push plate 83 to move accordingly, so that the spray pipe 6 can swing accordingly within a certain angle. When the spray pipe 6 swings to 45 degrees, the water flow sprayed by the nozzle assembly 7 at this time is the farthest, thereby making the overall range wider, so that water can be sprayed to a larger range of positions in the rice field, so that the oxygen content in the water in the rice field is more uniform.

[0034] A jet pipe 6 is rotatably mounted between the two support seats 5, and is provided with a nozzle 1 71, a nozzle 2 72, and a nozzle 3 73 on the jet pipe 6. The nozzle 2 72 and the nozzle 3 73 are arranged on the left and right sides of the nozzle 1 71 and are tilted. The sprayed water flows toward both sides. During the spraying process of the nozzle assembly 7, the swing mechanism 8 can swing the jet pipe accordingly within a certain angle, so that the range of the water sprayed by the nozzle assembly 7 is larger, thereby making the water fall over a wider range, so that the oxygen content in the water in the rice field is more uniform.

[0035] The water outlet pipe in the device is a hose, and its length and position can be adjusted accordingly according to needs, so that the jet pipe 6 and the swing mechanism 8 can be in any position, which is suitable for oxygenation operations in various positions of the rice field.

[0036] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention.
