[0002] A green manure intercropping sowing device is a mechanical device used in agricultural production to sow green manure crops between existing crop rows. Its main functions are to improve land utilization, improve soil structure, increase soil fertility, and promote the synergistic growth of crops and green manure. Traditional green manure intercropping sowing devices typically include basic components such as seed storage devices, sowing mechanisms, and power systems. These devices meet the basic requirements for green manure sowing to a certain extent, but they also have many shortcomings.
[0003] Most existing green manure intercropping seeding devices have simple structures, and their row spacing cannot be easily adjusted once determined, making them unsuitable for the diverse planting needs of different crop intercropping patterns. Furthermore, the seed dispensing method is relatively simple, making it difficult to achieve precise intermittent dispensing, resulting in insufficient sowing uniformity and accuracy, affecting the growth effect of green manure and the overall efficiency of the intercropping system. Moreover, the mechanical connection structure of existing devices has poor stability, making it difficult to adapt to complex and changing field operating environments, easily leading to loosening or damage of components, and causing mechanical damage to the green manure.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0022] like Figure 1 , 2 As shown in Figures 3 and 4, an adjustable row spacing green manure intercropping sowing structure includes a drive device 1. The adjustment structure 2, mechanically connected to the drive shaft, consists of a pair of symmetrically distributed threaded rods 3. An adjustment ring 4 is located above the threaded rods 3, and one side of the adjustment ring 4 is integrally connected to a discharge pipe 5. A limiting block 6 is fixedly connected to a limiting plate 7 below the storage pipe 5. Connecting rods 8 are fixedly connected to both ends of the adjustment assembly 2, one end connected to the drive device 1, and the other end inserted into the outer casing of the mechanical device. An extension connector 9 is fitted onto the outside of the connecting rods 8. Connecting flanges 10 are located at one end of the threaded rods 3, close to each other, and the other end is fixedly connected to the connecting rods 8. The threads are symmetrically distributed around the connecting flange 10. The adjustment ring 4 meshes with the threaded rods 3, and the threaded rods 3 drive the adjustment ring 4 to move towards the connecting flange 10. A seed intermittent feeding device is connected above the discharge pipe 5 via a connecting hose 11. The limiting plate 7 is composed of a blocking plate body clamped on both sides of the limiting block 6. The blocking plate body in the discharge direction has grooves 12 evenly distributed corresponding to the discharge pipe 5. The side of the blocking plate body close to the driving device 1 is fixedly connected to the support seat 13 that supports the driving device 1.
[0023] The aforementioned green manure intercropping sowing structure achieves adjustable row spacing through the coordination of a drive device and an adjustment mechanism. The threaded rod, adjusting ring, and other components in the adjustment mechanism interact with each other, while the connecting rod and extension connectors ensure a stable connection with the mechanical device. The design of the discharge pipe facilitates seed placement, and the structure of the limiting plate effectively limits the discharge. The overall design meets various needs of green manure intercropping sowing. In this implementation scheme,
[0024] In this implementation scheme, the drive device 1 serves as the core power source, providing power support for the row spacing adjustment of the entire sowing structure through its drive shaft mechanical connection with the adjustment structure 2. The threaded rods 3 in the adjustment structure 2 are symmetrically distributed and mesh with the adjustment ring 4. When the drive device 1 is activated, the threaded rods 3 drive the adjustment ring 4 to move along its axial direction, achieving precise adjustment of the row spacing. The discharge pipe 5 is integrally connected to the adjustment ring 4. As the adjustment ring 4 moves, the position of the discharge pipe 5 changes accordingly, thus adapting to the seed dispensing requirements under different row spacings. The storage pipe 5 is fixedly connected to the limiting plate 7 via a limiting block 6. The groove 12 on the limiting plate 7 corresponds to the discharge pipe 5, ensuring that the seeds can be accurately and evenly dispensed to the predetermined position.
[0025] Both ends of the connecting rod 8 are fixedly connected to the adjusting structure 2 and the driving device 1, respectively. One end is inserted into the housing of the mechanical device, and the other end is connected to the threaded rod 3, forming a stable mechanical connection. The extension connector 9 sleeved on the outside of the connecting rod 8 further enhances the connection strength and stability with the mechanical device, ensuring that the entire sowing structure can maintain stable operation in complex field working environments. The threaded rod 3 has a connecting flange 10 sleeved on one end close to the other, and the threads are symmetrically distributed with the connecting flange 10 as the axis. This design allows the adjusting ring 4 to remain smooth during movement, avoiding offset or jamming, and improving the accuracy and reliability of row spacing adjustment.
[0026] The discharge pipe 5 is connected to an intermittent seed feeding device via a connecting hose 11, enabling intermittent seed feeding. This allows for precise control of the seed feeding amount and timing based on actual planting needs, improving the uniformity and accuracy of sowing. The limiting plate 7 consists of blocking plates clamped on both sides of the limiting block 6. A support base 13 is fixedly connected to the side of the plate closest to the drive device 1. The support base 13 provides stable support for the drive device 1, ensuring its stability during operation and extending its service life.
[0027] It should be noted that this green manure intercropping sowing structure achieves field operations by connecting to the traction or suspension system of commonly used agricultural machinery such as tractors. The tractor's power take-off shaft (PTO) provides power to the drive unit 1, which can use a conventional gear or chain drive mechanism to drive the adjustment structure 2. During installation, the extension connector 9 of this device must first be securely assembled with the tractor's matching connecting parts to ensure that the entire sowing structure experiences even stress and operates smoothly during operation. This involves standardized connection and installation techniques for agricultural machinery.
[0028] Before sowing, seeds typically undergo pretreatment processes such as screening and coating. Screening can be done using existing vibrating screens to remove broken grains and impurities. Coating uses commercially available seed coating agents in conjunction with a dedicated seed coating machine to enhance seed resistance to pests and diseases and improve germination vigor. During installation, the connection between the storage pipe 5 and the discharge pipe 5 must be sealed with a sealing gasket using existing technology to prevent seed leakage. The connection between the connecting hose 11 and the intermittent seed feeding device is achieved through a quick-connect fitting technology. The intermittent seed feeding device itself can be an existing electromagnetic vibrating feeder or a metering screw feeder. By controlling its operating frequency, the seed dispensing rate can be adjusted to meet the precise sowing needs under different row spacings and planting densities.
[0029] During operation, the driver manipulates the tractor to travel at a constant speed along the preset sowing route. Simultaneously, the tractor's hydraulic or electronic control system sends adjustment signals to the device. Upon receiving the signal, the drive unit 1 rotates the threaded rod 3. The threaded rod 3 cooperates with the adjusting ring 4, causing the adjusting ring 4 to move the discharge pipe 5 in a set direction, thereby adjusting the row spacing. At this time, the groove 12 on the limit plate 7, in conjunction with the discharge pipe 5, ensures that the seeds accurately fall into the soil. After sowing, the device can be cleaned and maintained using a combination of high-pressure water jet washing and compressed air drying. Easily worn parts such as the discharge pipe 5 and connecting hose 11 should be inspected and replaced regularly to ensure the device's durability and reliability. Throughout the entire process, existing agricultural machinery technology, seed processing techniques, and hydraulic or electronic control methods are fully utilized, enabling this green manure intercropping sowing structure to efficiently and accurately complete the sowing task and seamlessly integrate with modern agricultural production systems, providing farmers with a complete and practical green manure intercropping sowing solution.
[0030] In one or more feasible embodiments, in practical applications, this green manure intercropping sowing structure will also be used in conjunction with agricultural machinery such as tractors, performing field operations via traction or suspension, which involves existing agricultural machinery connection and traction technologies. During the sowing process, existing seed treatment technologies, such as seed coating and disinfection, may also be required to improve seed germination rate and disease resistance. Furthermore, the storage pipe 5 in this device can be made of PVC material, which has good corrosion resistance and lightweight properties; the adjusting ring 4 and threaded rod 3 are made of high-strength aluminum alloy material, ensuring structural strength while reducing overall weight; the connecting hose 11 of the discharge pipe 5 can be made of wear-resistant and flexible rubber material to adapt to complex field operating environments. The application of these existing technologies and materials makes this device more complete and reliable in practical use, better meeting the needs of green manure intercropping sowing.
[0031] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
