Description

Technical Field

[0001] This invention belongs to the field of aquaculture technology, and specifically relates to a device for raising ducks in rice paddies. Background Technology

[0002] Rice-duck farming is an ecological farming model that primarily cultivates rice while simultaneously raising ducks. This model leverages the interaction between rice and ducks, including their environmental and food chain relationships, to achieve sustainable agricultural production. Specifically, the practice involves the ducks consuming weeds and pests in the rice paddies. Their activity also loosens the soil, massages it, and stimulates rice tillering, creating a fertilizing effect. This practice not only increases the organic content of the rice but also reduces the use of chemical fertilizers and pesticides, achieving purely green rice production. Furthermore, rice-duck farming, also known as "rice-duck farming," is an effective ecological agricultural technology aimed at minimizing pollution in rice-growing areas while saving on planting and raising costs, producing high-quality, green, organic rice and duck meat.

[0003] Currently, rice-duck farming does not present the same difficulties as rice-fish farming in terms of fertilization and pesticide application. However, the daily management of ducks has certain drawbacks, especially in terms of counting and feeding, which is quite cumbersome. In particular, when raising ducks on a large scale in rice fields, it is impossible to achieve refined management, which requires further improvement. Summary of the Invention

[0004] This invention provides a device for raising ducks in rice paddies, which solves the drawbacks of cumbersome management and the lack of refined management in the current rice-duck farming process. It can automate the management of duck farming while rice is being grown, thereby achieving the goals of increasing rice production, reducing pests, reducing inputs, facilitating management, and producing organic rice-duck agricultural products.

[0005] To solve the above problems, the technical solution provided by the present invention is as follows:

[0006] This invention provides a device for raising ducks in rice paddies, comprising multiple support pillars located above a puddle in the rice paddy, a duck house platform fixed to the support pillars, and a duck house roof. Photovoltaic panels are installed on the duck house roof. Four walls are provided between the duck house platform and the duck house roof, one of which has a duck house door. The duck house door includes a curtain rod and an automatic door. The curtain rod is a tightly arranged curtain that is breathable and prevents insects. The automatic door opens automatically at dawn and closes automatically at dusk. Black lights are installed under the duck house platform to attract and trap insects.

[0007] According to an optional embodiment of the present invention, the automatic door includes a door panel, a first link, a second link, a motor shaft, a control panel, and a contact switch; the door panel has a sliding opening and closing function, the door panel is connected to the first link via a movable joint, the first link is connected to the second link via a movable joint, and the end of the second link is provided with a ring, the ring being rotatable on the motor shaft;

[0008] The control panel includes a lever arm and a generator thereon. The control panel is circular, with its central hole fixed to the motor shaft. The motor shaft can drive the control panel to rotate. The generator is located on the edge of the control panel. The generator includes a small column, a fixed rod, and a frustum head. The small column has two planar structures perpendicular to the control panel. The second connecting rod is located between these two planar structures. The frustum head is fixed to the small column by the fixed rod. The frustum head is frustum-shaped and arranged outwards relative to each other along a tangent direction larger than the diameter of the control panel. When the motor shaft drives the control panel to rotate, the small column of the generator drives the second connecting rod to rotate around the motor shaft and pushes and pulls the first connecting rod, thereby driving the opening and closing of the door panel. The opening and closing of the door panel is controlled by the frustum head and the contact switch. When the door panel is fully open, the frustum head triggers the contact switch at one end, disconnecting the automatic control circuit and stopping the motor shaft. When the door panel is fully closed, the frustum head triggers the contact switch at the other end, disconnecting the automatic control circuit and stopping the motor shaft.

[0009] According to an optional embodiment of the present invention, the contact switch includes a housing, an inner ridge, a frustum-shaped nut, a separating post, a closing device, and a wire; the housing is cylindrical and hollow, and has an inner ridge. The frustum-shaped nut is fitted inside the housing through the inner ridge and can only slide left and right but cannot rotate; the frustum-shaped nut includes a piston body, a spring ring post, a spring ring, a figure-eight rod, and a latch on the figure-eight rod. The spring ring is vertically fixed inside the piston body through the spring ring post, and the figure-eight rod is fixed on the other side of the piston body. The latch functions to lock the figure-eight rod when the frustum head is inserted into it. The separating post opens the latch further and loses its locking function when the figure-eight rod moves outward.

[0010] According to an optional embodiment of the present invention, the closing device includes a lever arm, a pivot point, a spring rod, a stress spring, an insulating base, a metal sheet, and a wire; two lever arms are arranged side by side, with their outer ends opening in a flared shape; the lever arms are fixed to the pivot point and rotate; the distance between the pivot points is smaller than the diameter of the stress spring; a spring rod is provided on one side of the pivot point, perpendicular to the outward direction of the lever arms; the two ends of the spring rod are pulled by the stress spring; the inward ends of the lever arms are respectively fixed to the insulating base; a metal sheet is installed on the insulating base, and a wire is connected to each of the metal sheets; due to the action of the stress spring, the two metal sheets are in a closed or open state, that is, the automatic control circuit is in a closed or open state;

[0011] When the frustum head is inserted into the figure-eight rod and the frustum nut is pushed inward, the spring ring is inserted into the closure device. Its elastic force, combined with the stress spring, causes the closure device to open completely instantly, and the automatic control circuit is disconnected. When the spring ring is pulled out of the closure device, the elastic force of the spring ring, combined with the stress spring, causes the closure device to close completely instantly, and the automatic control circuit is closed. Correspondingly, when the frustum head is pulled out, the figure-eight rod opens wider due to the action of the separating column, the latch loses its restraint, and the frustum head is pulled out from the figure-eight rod, thus completing the function of disconnecting upon contact and closing upon removal.

[0012] According to an optional embodiment of the present invention, the automatic control circuit is powered by the photovoltaic panel, and the photosensitive switch of the automatic control circuit controls the conduction and shutdown at different time points, the forward and reverse rotation of the motor, the opening and closing of the automatic door, and the black light automatically controls the conduction to kill insects at night.

[0013] Beneficial Effects: This invention provides a device for raising ducks in rice paddies, including multiple support pillars located above waterlogged areas in the rice paddies, a duck house platform fixed to the support pillars, and a duck house roof. Photovoltaic panels are installed on the duck house roof. Four walls are provided between the duck house platform and the duck house roof, one of which has a duck house door. The duck house door includes a curtain rod and an automatic door. The curtain rod is a tightly arranged curtain that is breathable and prevents insects. The automatic door opens automatically at dawn and closes automatically at dusk. Black lights are installed under the duck house platform to attract insects. Using this device for raising ducks in rice paddies saves land, increases rice yield, and automates duck farming management. It reduces the costs of rice planting and duck raising, and improves the quality of rice-duck products due to reduced use of chemical fertilizers and pesticides. Attached Figure Description

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] like Figure 1As shown, paddy field 1 is modified by setting up a perimeter fence 2 around it to enclose the paddy field where ducks will be raised. An inlet channel 3 and a water-filled pond 4 are installed inside paddy field 1, with a duck-raising device 5 installed above the water-filled pond 4. The water-filled pond 4 is located at the center of gravity of paddy field 1, approximately 50 centimeters deep, and has an area of ​​approximately 30 square meters per acre of paddy field. No rice is planted in the water-filled pond 4. The pond 4 is surrounded by embankments with multiple openings into the paddy field. The water inlet of paddy field 1 is located inside the water-filled pond. Water from outside the paddy field is connected to the water-filled pond 4 via the small channel 3. The embankments are suitable for personnel to walk on and their height does not interfere with the operation of harvesters. This invention enables duck farming in paddy fields, achieving a mutually beneficial relationship between rice cultivation and duck raising.

[0026] like Figure 2 and Figure 3 As shown, this embodiment of the invention provides a device 5 for raising ducks in rice paddies, including multiple support pillars 6 located above a puddle 4 in the rice paddy 1, a duck house platform 7 fixed to the support pillars 6, and a duck house roof 8. A photovoltaic panel 9 is installed on the duck house roof 8. Four walls are provided between the duck house platform 7 and the duck house roof 9, one of which has a duck house door. The duck house door includes a curtain rod 9 and an automatic door 10. The curtain rod 9 is a tightly arranged curtain, breathable and insect-proof; the automatic door 10 automatically opens at dawn and closes at dusk, facilitating duck access. A black light is installed under the duck house platform 7 to attract and trap insects. In this embodiment, the multiple support pillars 6 stand in the puddle 4, supporting the duck house platform 7, which is about 1.5 meters above the normal water level of the puddle 4. A ramp 7-1 connects the rice paddy 4 and the duck house platform 7. The photovoltaic panel 9 is placed on the duck house roof 8. The duck house (device 5) is surrounded by netting in summer and insulation film in winter. Black lights are installed under platform 7 of the duck house to attract insects. The duck house door consists of an upper curtain-style door and a lower automatic door.

[0027] like Figure 3 and Figure 4 As shown, the automatic door 10 includes a door panel 11, a first link 13, a second link 14, a motor shaft 16, a control panel 15, and a contact switch 17. The door panel 11 has a sliding opening and closing function. The door panel 11 is connected to the first link 13 via a movable joint 12. The first link 13 is in turn connected to the second link 14 via a movable joint 12. The end of the second link 14 is provided with a ring, which can be rotated on the motor shaft 16.

[0028] like Figure 4 and Figure 5As shown, the control disk 15 includes a lever arm disk 15-1 and a generator 15-2 on it. The control disk 15 is a circular disk, with its central hole fixed to the motor shaft 16. The motor shaft 16 can drive the control disk 15 to rotate. The generator 15-2 is provided on the edge of the control disk 15. The generator 15-2 includes a small column 15-3, a fixing rod 15-4, and a frustum head 15-5. The small column 15-3 has two planar structures perpendicular to the control disk, and the second connecting rod 2 is located between the two planar structures. The frustum head 15-5 is fixed to the small column 15-3 by the fixing rod 15-4. The frustum head 15-5 is frustum-shaped and is arranged relatively outward along the tangent direction of the circle larger than the diameter of the control disk 15. When the motor shaft 16 drives the control panel to rotate, the small column of the generator drives the second connecting rod 2 to rotate around the motor shaft, and pushes and pulls the first connecting rod 13 to drive the opening and closing of the door panel 11. The opening and closing of the door panel 11 is controlled by the cone head 15-5 and the contact switch 17. When the door panel 11 is fully open, the cone head 15-5 triggers the contact switch 17 at one end, causing the automatic control circuit to disconnect and the motor shaft 16 to stop. When the door panel 11 is fully closed, the cone head 15-5 triggers the contact switch 17 at the other end, causing the automatic control circuit to disconnect and the motor shaft 16 to stop.

[0029] like Figure 6 , Figure 7 and Figure 8 As shown, the contact switch 17 includes a housing 18, an inner ridge 19, a frustum nut 20, a separating post 21, a closing device 22, and a wire 23. The housing 18 is a hollow column with an inner ridge 19. The frustum nut 20 is fitted inside the housing 18 through the inner ridge 19 and can only slide left and right, not rotate. The frustum nut 20 includes a piston body 30, a spring ring post 32, a spring ring 31, a figure-eight rod 33, and a latch 34 on the figure-eight rod 33. The spring ring 31 is vertically fixed inside the piston body 30 by the spring ring post 32. The figure-eight rod 33 is fixed on the other side of the piston body 30. The latch 34 locks the figure-eight rod 33 when the frustum head 15-5 is inserted into it. The separating post 21 opens the figure-eight rod 33 further when it moves outward, causing the latch 34 to lose its locking function.

[0030] The closing device 22 includes lever arms 24, a pivot point 28, a spring rod 29, a stress spring 27, an insulating base 25, a metal plate 26, and a wire 23. Two lever arms 24 are arranged side-by-side, with their outer ends flared outwards like a trumpet. The lever arms 24 are fixed to the pivot point 28 and rotate. The distance between the pivot points 28 is less than the diameter of the stress spring 27. A spring rod perpendicular to the outward direction of the lever arms 29 is provided on one side of the pivot point 28. The two ends of the spring rod 29 are pulled by the stress spring 27. Insulating bases 25 are fixed to the inward ends of the lever arms 24, and metal plates 26 are mounted on the insulating bases 25, each connected to a wire 23. Due to the action of the stress spring 27, the two metal plates 26 are in a closed or open state, i.e., the automatic control circuit is in a closed or open state.

[0031] When the frustum head 15-5 is inserted into the figure-eight rod 33 and pushes the frustum nut 20 inward, the spring ring 31 is inserted into the closure device 22. Its elastic force, combined with the stress spring 27, causes the closure device 22 to open completely instantly, and the automatic control circuit is disconnected. When the spring ring 31 is pulled out of the closure device 22, the elastic force of the spring ring 31, combined with the stress spring 27, causes the closure device 22 to close completely instantly, and the automatic control circuit is closed. Correspondingly, when the frustum head 15-5 is pulled out, the figure-eight rod 33 opens further due to the action of the separating column 21, the latch 34 loses its restraint, and the frustum head 15-5 is pulled out from the figure-eight rod 33, thus completing the function of disconnecting when in contact and closing when pulled out.

[0032] like Figure 9 As shown, the automatic control circuit is powered by photovoltaic panel 9. The photosensitive switch of the automatic control circuit controls the conduction and shutdown at different times, the forward and reverse rotation of the motor, the opening and closing of the automatic door, and the black light automatically controls the conduction to kill insects at night. Figure 9 In the diagram, L is the dark switch, D is the light switch, and K... D K is the stop contact switch for opening the duck house door. L M is the contact switch for closing the duck house door, 9 is the black light, 35 is the photovoltaic panel, 16 is the battery, and 15-5 is the cone head.

[0033] Example 1

[0034] There are 80 mu (approximately 5.3 hectares) of existing paddy fields designated for duck farming, with each paddy field covering about 10 mu (approximately 0.67 hectares). The duck stocking density is 80 ducks per mu (approximately 0.067 hectares). The specific implementation will utilize the aforementioned technical scheme for paddy field duck farming. A water-filled pond is constructed at the center of gravity of the paddy field, 50 cm deeper than the paddy field level, with an area of ​​25 square meters per mu (approximately 1.7 hectares) of paddy field. No rice is planted in the pond. The pond is surrounded by embankments with multiple openings leading to the paddy field. The paddy field's water inlet is located within the pond. Water from outside the paddy field is connected to the pond via a small canal. The canal embankments are suitable for personnel walking and their height does not interfere with harvester operations. The duck house platform is approximately 1.5 meters above the normal water level of the pond, with a ramp connecting the paddy field and the duck house platform. Photovoltaic panels are placed on the roof of the duck house. The duck house is surrounded by mesh in summer and insulation film in winter. Black light lamps are installed under the duck house platform for attracting insects. The duck house door consists of an upper curtain-style door and a lower automatic door. The automatic door opens at dawn and closes automatically at dusk, making it convenient for the ducks to come and go.

[0035] After the paddy field is transformed, rice can be planted first and then ducks released, or ducks can be raised first and then rice planted, depending on actual needs. Rice planting should be spaced out to allow the ducks room to move around. Fertilization and pesticide application can be carried out using conventional methods. When the rice harvest is earlier than the duck harvest, the paddy field should be flooded after the rice is harvested to allow the ducks to move around. When releasing the ducks, they should first be kept in the duck house for three days, during which time they should be provided with drinking water and food. After three days, the automatic gate system should be activated. Duck droppings will fall from the platform into the paddy field and will flow into the entire paddy field when water is injected, thus providing even fertilization.

[0036] After the rice and ducks were harvested, the average yield of rice increased by 50 jin per mu and the number of commercial ducks increased by 80 (5 jin each), achieving remarkable results.

[0037] Example 2

[0038] There are 10 mu (approximately 1.65 acres) of paddy fields designated for duck farming, with each paddy field containing about 5 mu (approximately 0.85 acres). The duck density is 60 ducks per mu (approximately 0.16 acres). The specific implementation will utilize the aforementioned technical scheme for paddy field duck farming. A water-filled pond is constructed at the center of gravity of the paddy field, 60 cm deeper than the paddy field level, with an area of ​​30 square meters per mu (approximately 1.5 acres). No rice is planted in the pond. The pond is surrounded by embankments with multiple openings leading to the paddy field. The paddy field's water inlet is located within the pond. Water from outside the paddy field is connected to the pond via a small canal. The canal embankments are suitable for personnel walking and their height does not interfere with harvester operations. The duck house platform is approximately 1 meter above the normal water level of the pond, with a ramp connecting the paddy field and the duck house platform. Photovoltaic panels are placed on the roof of the duck house. The duck house is surrounded by mesh in summer and insulation film in winter. Black light lamps are installed under the duck house platform for attracting insects. The duck house door consists of an upper curtain-style door and a lower automatic door. The automatic door opens at dawn and closes automatically at dusk, making it convenient for the ducks to come and go.

[0039] After the paddy field renovation is completed, ducks will be raised first, followed by rice planting, based on actual needs. During rice planting, the ducks will be temporarily kept in duck sheds. Rice plants should be spaced out to allow the ducks room to move around. Fertilization and pesticide application can be carried out using conventional methods. When releasing the ducks, they will initially be kept in the duck sheds for 3 days, during which time they will be provided with water and food. After 3 days, the automatic gate system will be activated. Duck droppings will fall from the platform into the paddy field and, when water is injected, will flow into the entire paddy field, providing even fertilization.

[0040] After the rice and ducks were harvested, the average yield of rice increased by 55 jin per mu, and the number of marketable ducks increased by 60 (6 jin each), achieving remarkable results.

[0041] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
