Abstract
Description
Technical Field
[0001] This invention relates to the technical field of agricultural production equipment, specifically to a hybrid rice pollination device and a method for using the hybrid rice pollination device. Background Technology
[0002] Pollination is a crucial step in the cultivation of hybrid rice. Currently, pollination of hybrid rice mainly relies on manual assistance or traditional agricultural machinery. Manual pollination typically involves an operator walking along the paddy field and gently tapping the rice plants with a hand-held baton. This method is obviously inefficient, requires a large amount of manpower and time, and is labor-intensive, making it unsuitable for large-scale cultivation. Traditional agricultural machinery, such as tractors, often damages the rice stalks during use, affecting the yield and quality of the rice.
[0003] To address these issues, some regions have adopted drones to pollinate rice paddies in recent years. While this method is highly efficient, it relies on the wind power of the drones to lift the rice pollen, which is easily carried away by the wind, resulting in significant losses and low pollination quality. Summary of the Invention
[0004] The purpose of this invention is to provide a hybrid rice pollination device that can effectively improve pollination quality. To address the aforementioned problems, this invention provides a hybrid rice pollination device, comprising a traction plate and a support shell. The front and rear ends of the traction plate are conical, resulting in a spindle-shaped planar shape. Multiple grooves distributed along the front-to-back direction are provided on the left and right sides of the traction plate, respectively. These grooves are arc-shaped, creating a wave-like pattern on the left and right sides of the traction plate. A stepped platform protruding laterally is provided at the lower part of each groove, and this stepped platform is concave-arc-shaped. The support shell is connected to the lower side of the traction plate and is an elongated strip extending from front to back, with a width smaller than the width of the traction plate.
[0005] Compared to existing technologies, the above solution first designs a spindle-shaped traction plate. This plate is used to move through the paddy field and separate the rice plants. The front and rear ends of the traction plate are conical, effectively reducing resistance during movement and allowing for smoother movement. The grooves on the left and right sides of the traction plate create a shaking effect as it passes over the rice stalks, effectively increasing pollen dispersal. This causes some pollen to be quickly lifted for pollination, while some pollen scatters and accumulates on the stepped platform, moving with the traction plate to other locations for further pollination. The design achieves better pollination, and the arc-shaped grooves better adapt to the growth pattern of the rice stalks, preventing excessive damage to the stalks during pushing and ensuring normal rice growth. Furthermore, since the traction plate has a certain width, it may experience deflection forces when moving in the paddy field. The above solution further incorporates a support shell on the underside of the traction plate. Because the support shell is a long strip extending from front to back and its width is smaller than the traction plate, it provides guidance in the front-to-back direction, effectively reducing the probability of the traction plate tilting and ensuring the accuracy of its movement.
[0006] In an improved embodiment, the support shell is equipped with a pollen-blowing assembly for blowing air onto the left and right sides of the traction plate. By adding the pollen-blowing assembly, the rice panicles can be blown, further promoting pollen dispersal.
[0007] In an improved embodiment, the powder blowing assembly includes an air inlet pipe, an air pump, an air outlet pipe, and at least two nozzles. The nozzles are located on the upper side of the traction plate, with at least one nozzle facing left and at least one nozzle facing right. One end of the air inlet pipe is connected to the air pump, and the other end extends to the outside of the support shell. The air outlet pipe connects the air pump and all the nozzles, so that the air pump takes in air through the air inlet pipe and delivers the gas to the nozzles through the air outlet pipe to achieve blowing.
[0008] In an improved embodiment, the traction plate has a vertically penetrating and front-back extending assembly hole in the middle. There are two air intake pipes, which are vertically connected to the front and rear parts of the upper side of the support shell, respectively. The two air intake pipes are respectively snapped into the front and rear walls of the assembly hole, so that the support shell is assembled with the traction plate through the air intake pipes.
[0009] In an improved embodiment, a nozzle is disposed between any two adjacent grooves on the left side of the traction plate, and a nozzle is disposed between any two adjacent grooves on the right side of the traction plate. Each nozzle has forward and backward air holes. When the traction plate moves forward or backward, the forward and backward air holes of the nozzles can effectively blow up the pollen on the rice stalks in the adjacent grooves, ensuring that the pollen can be spread more widely.
[0010] In an improved embodiment, the front and rear ends of the support shell are rounded, and the width of the support shell gradually decreases from top to bottom, so that the support shell forms a boat shape. The boat-shaped support shell can contact the rice stalks in advance during the movement of the traction plate and cause the rice stalks to bend, further reducing the resistance of the traction plate and the probability of deflection.
[0011] The present invention also provides a method for using a hybrid rice pollination device, including the hybrid rice pollination device as described above, comprising the following steps: the hybrid rice pollination device is hoisted by a drone, and the traction plate of the hybrid rice pollination device is adjusted to be at the same height as the rice flowers. Then, the drone plans its flight trajectory according to the row arrangement of the rice field. Starting from the front of the first row of rice, the drone first flies the hybrid rice pollination device from front to back over the first row of rice. Then the drone flies to the back of the second row of rice and then flies from back to front over the second row of rice. Subsequently, for every odd-numbered row of rice, the drone flies from front to back, and for every even-numbered row of rice, the drone flies from back to front, until all the rice has been covered.
[0012] Drones are characterized by their flexibility and maneuverability. The above solution uses drones to hoist hybrid rice pollination devices, enabling the devices to fly over rice paddies. The drones can adjust their flight path and altitude as needed, making them adaptable to rice paddies of different terrains and sizes. This approach is highly versatile and effectively avoids the damage to rice stalks caused by traditional agricultural machinery when driving through rice paddies. Furthermore, the drones' flight path is an S-shaped loop, resulting in high mobility.
[0013] The present invention also provides a method for using a hybrid rice pollination device, comprising the hybrid rice pollination device as described above, including the following steps: Guide wheels are respectively installed at both ends of the first row of rice in the paddy field, and a traction rope is wound between the two guide wheels. The hybrid rice pollination device is then connected to the traction rope so that it is positioned in front of the first row of rice, ensuring that the traction plate of the hybrid rice pollination device is at the same height as the rice flowers. The traction rope is then pulled to allow the hybrid rice pollination device to pass through the first row of rice from front to back. The two guide wheels are then moved to both ends of the second row of rice, and the traction rope is pulled to allow the hybrid rice pollination device to pass through the second row of rice from back to front. Subsequently, for every odd-numbered row of rice, the traction rope is pulled to move the hybrid rice pollination device from front to back, and for every even-numbered row of rice, the traction rope is pulled to move the hybrid rice pollination device from back to front, until it passes through all the rice.
[0014] The above-mentioned scheme moves the hybrid rice pollination device across the paddy field by pulling it with a traction rope. It has a simple structure, low cost, and is suitable for paddy field operations of various sizes. Attached Figure Description

[0020] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0021] Example 1: Please refer to Figures 1-4The present invention provides a hybrid rice pollination device in embodiment 1, comprising a traction plate 1 and a support shell 2. The front and rear ends of the traction plate 1 are conical so that the planar shape of the traction plate 1 is spindle-shaped. The left and right sides of the traction plate 1 are respectively provided with a plurality of grooves 11 distributed in the front-back direction. The grooves 11 are arc-shaped so that the left and right sides of the traction plate 1 form a wave shape. The lower part of the grooves 11 is provided with a stepped platform 12 protruding in the transverse direction. The stepped platform 12 is concave arc-shaped. The support shell 2 is connected to the lower side of the traction plate 1. The support shell 2 is a long strip extending from front to back and the width of the support shell 2 is smaller than the width of the traction plate 1.
[0022] Compared with existing technologies, the above solution first designs a spindle-shaped traction plate 1, which is used to move in the paddy field and separate the rice plants. The front and rear ends of the traction plate 1 are conical, effectively reducing resistance when moving in the paddy field and allowing it to move more smoothly. The grooves 11 on the left and right sides of the traction plate 1 push the rice stalks as it passes through, creating a shaking effect that effectively increases pollen dispersal. This causes some pollen to be quickly lifted for pollination, while some pollen is scattered and accumulated on the stepped platform 12, and moves to other positions with the traction plate 1. To achieve better pollination, the arc-shaped groove 11 better adapts to the growth pattern of the rice stalks, preventing excessive damage to the stalks during pushing and ensuring normal rice growth. Furthermore, since the traction plate 1 has a certain width, it may experience deflection forces when moving in the paddy field. The above solution further incorporates a support shell 2 on the underside of the traction plate 1. Because the support shell 2 is a long strip extending from front to back and its width is smaller than that of the traction plate 1, it provides guidance in the front-to-back direction, effectively reducing the probability of the traction plate 1 tilting and ensuring the accuracy of its movement. It should also be noted that the width of the traction plate 1 and the width of the support shell 2 refer to... Figure 3 The dimensions in the left and right directions are based on this.
[0023] In this embodiment, the front and rear ends of the support shell 2 are rounded, and the width D of the support shell 2 gradually decreases from top to bottom, so that the support shell 2 forms a boat shape. The boat-shaped support shell 2 can contact the rice straw in advance during the movement of the traction plate 1 and cause the rice straw to bend, further reducing the resistance of the traction plate 1 and the probability of deflection.
[0024] As an improvement to the above embodiment, the support shell 2 is equipped with a pollen-blowing assembly for blowing air onto the left and right sides of the traction plate 1. By adding the pollen-blowing assembly, the rice panicles can be blown, further promoting pollen dispersal.
[0025] The specific form of the powder blowing assembly is not limited in this design, as long as it can blow air onto the rice paddies; for example, it can be a blower positioned to the left or right. In this embodiment, the powder blowing assembly includes an air inlet pipe 31, an air pump 32, an air outlet pipe 33, and at least two nozzles 34. The nozzles 34 are located on the upper side of the traction plate 1, with at least one nozzle 34 facing to the left and at least one nozzle 34 facing to the right. One end of the air inlet pipe 31 is connected to the air pump 32, and the other end extends to the outside of the support shell 2. The air outlet pipe 33 connects the air pump 32 and all the nozzles 34, so that the air pump 32 takes in air through the air inlet pipe 31 and delivers the gas to the nozzles 34 through the air outlet pipe 33 to achieve blowing. The air pump 32 integrates an independent power supply, thus providing power through an independent power source.
[0026] Furthermore, the middle of the traction plate 1 is provided with an assembly hole 13 that runs vertically through and extends in the front-back direction. There are two air intake pipes 31, which are vertically connected to the front and rear parts of the upper side of the support shell 2 respectively. The two air intake pipes 31 are respectively snapped into the front and rear walls of the assembly hole 13. The assembly between the support shell 2 and the traction plate 1 is realized through the interference fit between the two air intake pipes 31 and the front and rear walls of the assembly hole 13.
[0027] To achieve better airflow, this embodiment further includes a nozzle 34 positioned between any two adjacent grooves 11 on the left side of the traction plate 1 and another nozzle 34 positioned between any two adjacent grooves 11 on the right side of the traction plate 1. Each nozzle 34 has forward and backward air holes 341. The air outlet pipe 33 connects to the nozzles 34 and exhausts air through the forward and backward air holes 341. Thus, when the traction plate 1 moves forward or backward, the forward and backward air holes 341 of the nozzles 34 can effectively blow up the pollen on the rice stalks in the adjacent grooves 11, ensuring that the pollen can be spread more widely.
[0028] Example 2: Example 2 of the present invention provides a method for using a hybrid rice pollination device, which adopts the hybrid rice pollination device as in Example 1, including the following steps: The hybrid rice pollination device is hoisted by a drone, and the traction plate 1 of the hybrid rice pollination device is adjusted to be at the same height as the rice flowers. Then, the drone plans its flight trajectory according to the row arrangement of the rice field. Starting from the front of the first row of rice, the drone first flies the hybrid rice pollination device from front to back over the first row of rice. Then the drone flies to the back of the second row of rice, and then flies from back to front over the second row of rice. Subsequently, for every odd-numbered row of rice, the drone flies from front to back, and for every even-numbered row of rice, the drone flies from back to front, until it has flown over all the rice.
[0029] Drones are characterized by their flexibility and maneuverability. The above solution uses drones to hoist hybrid rice pollination devices, enabling the devices to fly over rice paddies. The drones can adjust their flight path and altitude as needed, making them adaptable to rice paddies of different terrains and sizes. This approach is highly versatile and effectively avoids the damage to rice stalks caused by traditional agricultural machinery when driving through rice paddies. Furthermore, the drones' flight path is an S-shaped loop, resulting in high mobility.
[0030] Example 3: Example 3 of the present invention provides a method for using a hybrid rice pollination device, using the hybrid rice pollination device as described in Example 1, including the following steps: guide wheels are respectively set at both ends of the first row of rice in the paddy field, and a traction rope is wound between the two guide wheels. Then, the hybrid rice pollination device is connected to the traction rope so that the hybrid rice pollination device is in front of the first row of rice, and the traction plate 1 of the hybrid rice pollination device is at the same height as the rice flowers. Then, the traction rope is pulled so that the hybrid rice pollination device passes through the first row of rice from front to back. Then, the two guide wheels are moved to both ends of the second row of rice, and the traction rope is pulled so that the hybrid rice pollination device passes through the second row of rice from back to front. Then, for each odd-numbered row of rice, the traction rope is pulled so that the hybrid rice pollination device moves from front to back, and for each even-numbered row of rice, the traction rope is pulled so that the hybrid rice pollination device moves from back to front, until it passes through all the rice.
[0031] The above-mentioned scheme moves the hybrid rice pollination device across the paddy field by pulling it with a traction rope. It has a simple structure, low cost, and is suitable for paddy field operations of various sizes.
