Description

Technical Field

[0001] This utility model relates to the field of sowing device technology, specifically to a directional sowing device for the male parent of a stress-resistant hybrid maize. Background Technology

[0002] The directional sowing device for male parent of maize stress-resistant hybrid varieties is an agricultural machinery device that can accurately sow male parent seeds in a specific direction and position. It usually includes a directional seed metering mechanism, a sowing mechanism, and a conveying mechanism. This device can improve sowing efficiency and quality, ensure that the male parent seeds grow in the same direction, and provide convenience for maize hybrid seed production.

[0003] Under drought conditions, sowing corn seeds with the larger end down and the embryo up can promote faster root growth, narrower root angles, and higher deep root density. This root structure helps the seeds absorb more deep soil moisture, thereby improving the seeds' drought resistance and the growth quality of seedlings.

[0004] To address the challenges of drought during maize planting, existing techniques involve placing maize seeds in water. Because the seed's center of gravity is biased towards the larger end, the seed naturally maintains a stable posture with the larger end down and the smaller end up in the water. This method allows the male parent seed to be oriented and bear weight. However, the process of orienting the seeds in water is cumbersome and may affect planting efficiency, especially during large-scale mechanized planting, where this method is difficult to match with the operating speed of high-speed seeders. Therefore, to address these issues, a directional planting device for the male parent of a maize stress-resistant hybrid is proposed. Utility Model Content

[0030] As a further implementation of this solution, the discharge component 2 includes a material box 21. The rear end of the material box 21 is fixedly connected to the front end of the external frame 1. A seed trough 22 and a water trough 23 are provided inside the material box 21. A vibration motor 24 is fixedly connected inside the seed trough 22. Through the above settings, the overall structure of the device is ensured to be stable. The seed trough 22 and the water trough 23 provide space for the storage of seeds and water. The fixed connection of the vibration motor 24 provides a basis for subsequent vibration operation, thereby realizing the initial orientation of the seeds and laying the foundation for subsequent precise sowing.

[0031] As a further implementation of this solution, the lower end of the feed box 21 is provided with multiple through holes. The bottom end of the feed box 21 is fixedly connected to the top end of the second feed cylinder 32 and the first feed cylinder 31. The feed box 21 is connected to the inner side of the first feed cylinder 31 and the inner side of the second feed cylinder 32 through the through holes. Through the above arrangement, seeds and water can smoothly enter the first feed cylinder 31 and the second feed cylinder 32 from the feed box 21. The fixed connection between the first feed cylinder 31 and the second feed cylinder 32 and the feed box 21 ensures the stability of the structure. At the same time, the interconnection design ensures the smooth flow of seeds and water, improving the smoothness and efficiency of sowing.

[0032] As a further implementation of this solution, an electric telescopic rod 25 is fixedly connected to the bottom of the material box 21. A horizontal plate 26 is fixedly connected to the end of the piston rod of the electric telescopic rod 25. The bottom of the horizontal plate 26 is fixedly connected to the top of the vertical column 44. Through the above settings, a power transmission function is provided. The piston rod drives the horizontal plate 26 and the vertical column 44 to move, realizing the pushing and sowing of seeds, improving the automation and accuracy of sowing, reducing manual intervention, and reducing labor intensity.

[0033] As a further implementation of this solution, a cover plate is fixedly connected to the top of the collecting cylinder 34. The cover plate of the collecting cylinder 34 has multiple through holes. The inner side of the first cylinder 31 and the inner side of the second cylinder 32 are both connected to the collecting trough 35. Through the above arrangement, the cover plate prevents the seeds and water from leaking out during the movement. The multiple through holes ensure that the seeds and water enter the collecting trough 35 smoothly. The connection design between the first cylinder 31 and the second cylinder 32 and the collecting trough 35 further optimizes the flow path of the seeds and water, ensuring the continuity and efficiency of the sowing process.

[0034] As a further implementation of this solution, the diameter of the collecting cylinder 34 is twice the diameter of the launching cylinder 36, the threaded bar 37 has a spiral structure, and there are multiple threaded bars 37.

The horn hole 39 passes through the inner side of the silicone sleeve 38 from top to bottom. The silicone sleeve 38 has a fitted structure. Through the above settings, the water flow loss inside the collecting trough 35 and the launching cylinder 36 can be reduced by the spiral design of the silicone sleeve 38. At the same time, the design of the silicone sleeve 38 can improve the stability of seed directional sowing when seeds and water are launched.

[0035] As a further implementation of this scheme, the air storage channel 42 is connected to the material collection trough 35, the air cylinder 41 is a hollow cylinder, the rubber ring 43 is a cylinder, and the number of power components 4 is the same as the number of feeding components 3. Through the above settings, the connection between the air storage channel 42 and the material collection trough 35 provides a channel for air pressure transmission.

[0036] Workflow: When directional sowing of corn seeds, corn seeds are placed inside the seed trough 22, and water is placed inside the water trough 23. The vibrating motor 24, solenoid valve 33, and electric telescopic rod 25 are electrically connected via an existing controller and battery. The external frame 1 is fixed to the existing locomotive. The vibrating motor 24 and solenoid valve 33 are indirectly started. Initially, the rubber ring 43 is positioned above the air cylinder 41. After the vibrating motor 24 starts, it vibrates the feed box 21. Under the action of vibration, the corn seeds inside the seed trough 22 enter the first feed cylinder 31. After passing through the first feed cylinder 31... Upon entering the collection trough 35, after the solenoid valve 33 is opened, water from the water tank 23 enters the collection trough 35 through the second feed cylinder 32. At this point, both the launching cylinder 36 and the collection trough 35 are filled with water. Under the influence of gravity, the corn seeds are positioned with their larger ends facing down. Simultaneously, the vibration motor 24 and the solenoid valve 33 are closed. The electric telescopic rod 25 is then activated, causing the horizontal plate 26 and multiple vertical columns 44 to move downwards. The vertical columns 44 push the rubber ring 43 downwards, allowing gas from the air storage channel 42 to enter the collection trough 35. 5. Internal air pressure expands. Under the action of air pressure expansion, the lower end of the horn hole 39 in the silicone sleeve 38 opens. At this time, the seeds and water inside the collection trough 35 and the launching cylinder 36 move downward through the inside of the launching cylinder 36. When passing through the threaded strip 37, the water inside the launching cylinder 36 can be made into a vortex state. In this way, the seeds inside the launching cylinder 36 and the collection trough 35 are in the middle of the vortex. When they are sprayed out through the inside of the silicone sleeve 38, the rubber ring 43 returns to its original position. At this time, the silicone sleeve 38 is deformed by the negative pressure of the gas. The narrow end of the silicone sleeve 38 moves upward, and the lower end of the silicone sleeve 38... The seeds are collected inside the horn hole 39. Under gas pressure, the horn hole 39 cracks open again, and gas enters the collection trough 35 and the launching tube 36, facilitating re-sowing and increasing the probability of the seed's larger end facing down. This planting method is suitable for use under drought conditions, allowing the corn seed's root system to grow faster, the root angle to be narrower, and the deep root density to be higher. Based on the above principles, the device can reduce the labor intensity of workers when planting corn seeds, while improving planting efficiency. It is suitable for large-scale mechanized sowing and improves the quality of corn seed planting.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
