Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery sowing, and in particular to a seed disturbance device and a sowing machine. Background Art

[0002] With the continuous development of modern agricultural production and the improvement of mechanization, sowing technology plays an increasingly important role in agricultural production. As an important part of agricultural machinery, the performance of the seeder directly affects the growth and yield of crops. The seeder is the core working part of the seeder. At present, the air-suction seeder is widely used in the market. The air-suction seeder uses the adsorption force of the airflow to adsorb the seeds on the seeding disc, and then sows the seeds evenly in the field by controlling the release of the airflow. This kind of seeder has the advantages of reducing seed damage, improving sowing uniformity and accuracy, and has become an indispensable equipment in modern agricultural production.

[0003] Existing air-suction seeders in agricultural production mostly use a boss structure on the seed tray to disturb the seeds. Specifically, the boss structure forms protrusions on the surface of the seed tray, and uses mechanical disturbance to make the seeds move and disperse to a certain extent on the seed tray, thereby achieving the purpose of seed disturbance. However, the effect of this seed disturbance method is not ideal. First, the boss structure has a poor seed disturbance effect and cannot effectively disperse the seeds, resulting in the accumulation of seeds on the seed tray, affecting the seed filling effect. Secondly, the seed disturbance range is small and cannot cover the entire seed tray, resulting in uneven sowing. Finally, the boss structure is fixed and lacks flexibility. It cannot adapt to the characteristics of different seeds, which limits the application scope of the air-suction seeder.

[0004] Therefore, there is an urgent need for an improved seed disturbance device to improve the seed disturbance effect and seed filling stability of the air suction seed metering device to meet the needs of modern agricultural production. Summary of the invention

[0039] Embodiment 1

[0040] The embodiment of the present invention provides a seed disturbance device, which can realize the seed disturbance process by combining air flow disturbance and mechanical seed disturbance.

[0041] See also Figure 1 and Figure 2 The seed disturbance device provided by the embodiment of the present invention includes a housing 10, a seed disturbance component 20 and a fan component 30. A seed filling space 101 is formed inside the housing 10, and a seed discharge port 11 is provided on the housing 10, and the seed discharge port 11 is connected to the seed filling space 101; the seed disturbance component 20 includes a connecting plate 21, an air flow pipe 24 and a blowing part, and a plurality of seed disturbance holes 211 are provided on the connecting plate 21, and the plurality of seed disturbance holes 211 penetrate the connecting plate 21 along the thickness direction of the connecting plate 21; an air flow channel is formed in the air flow pipe 24, and the connecting plate 21 is arranged between the seed discharge port 11 and the air flow pipe 24, and the seed disturbance holes 211 are connected to the seed filling space 101. The two ends of 1 are respectively connected to the seed filling space 101 and the air flow channel, the blowing part is arranged at the end of the air flow tube 24, and the blowing part can blow gas into the air flow channel; the seed disturbance fan 31 is arranged in the seed filling space 101, and the seed disturbance fan 31 includes a connecting rod 321, a seed disturbance blade 311 and a driving mechanism 32, the seed disturbance blade 311 is arranged on the connecting rod 321, the driving mechanism 32 is connected to the connecting rod 321, and the driving mechanism 32 can drive the seed disturbance blade 311 to rotate around the connecting rod 321.

[0042] Generally speaking, the seed disturbance device is placed horizontally, and the shell 10, the connecting plate 21 and the airflow pipe 24 are arranged in sequence from top to bottom in the vertical direction. For the convenience of description in conjunction with the drawings, the directions below are described in the directions shown in the drawings, but are not limited thereto.

[0043] In the seed filling state, the connecting plate 21 is installed at the seed discharge port 11 of the housing 10, and the airflow generated by the blowing part is blown into the seed filling space 101 through the airflow channel. After the airflow enters the seed filling space 101 through the seed disturbance hole 211, it will disturb the seeds in the seed filling cavity, thereby achieving the seed disturbance effect; at the same time, the driving mechanism 32 drives the seed disturbance fan 31 to rotate, and the seed disturbance fan 31 contacts the seeds, making the seed disturbance rate in the seed filling space 101 greater; in addition, the design of the seed disturbance fan 31 also has the function of guiding the seed flow direction, making it easier for the seeds to contact the seeding hole, improving the seed filling effect of the seeding device, and increasing the seed filling rate. The seed disturbance device ensures that the seeds can be effectively transported from the seed filling space 101 to the seed discharge port 11 through the seed filling space 101 formed inside the housing 10 and the seed discharge port 11 opened on the housing 10, optimizes the seed transportation path, and improves the seed filling efficiency. The design of the seed disturbance component 20, especially the cooperation of the connecting plate 21, the airflow tube 24 and the blowing part, can effectively use the airflow to disturb the seeds. The airflow channel is connected to the seed filling space 101 through a plurality of seed disturbance holes 211 on the connecting plate 21, so that the airflow can pass through the seed disturbance holes 211 to disturb the seeds, thereby improving the seed disturbance effect and ensuring the uniform distribution of the seeds in the seed filling space 101. The arrangement of the airflow tube 24 and the blowing part enables the airflow to be effectively introduced into the airflow channel and act on the seeds through the seed disturbance holes 211, avoiding the seed accumulation problem caused by the traditional boss structure, enhancing the seed disturbance effect, and solving the problem of poor seed disturbance effect in the prior art. The seed disturbance fan 31 is driven to rotate by the driving mechanism 32, so that the seed disturbance fan 31 can rotate in the seed filling space 101 to mechanically disturb the seeds. The seed disturbance effect is further enhanced, ensuring the uniform distribution of the seeds and the stability of the seed filling effect. The seed disturbance device combines airflow seed disturbance and mechanical seed disturbance, utilizing both the flexible effect of the airflow and the strong effect of the mechanical disturbance, achieving a more uniform and stable seed disturbance effect, avoiding the limitations of a single method, and improving the sowing quality and efficiency. The seed disturbance hole 211 on the connecting plate 21 is designed to make the connection between the airflow channel and the seed filling space 101 more flexible, and the strength and direction of the airflow can be adjusted according to actual needs, thereby enhancing the adaptability of the seed disturbance device, being able to adapt to the characteristics and sowing requirements of different seeds, and expanding the application scope of the air suction seed metering device. In summary, the seed disturbance device provided by the present invention effectively solves the problems of poor seed disturbance effect and unstable seed filling effect in the prior art, has a higher seed disturbance effect and seed filling stability, and has a higher adaptability.

[0044] In the present embodiment, the blowing part is a driving fan. The driving fan can provide continuous and strong airflow, effectively enhancing the disturbance effect on the seeds, and ensuring the uniform distribution and sufficient disturbance of the seeds in the seed filling space 101. The operator can flexibly adjust the working parameters of the driving fan according to the characteristics of different seeds and sowing requirements, so as to optimize the seed disturbance effect of the airflow, improve the accuracy and uniformity of seed filling, so that the seed disturbance device can adapt to a variety of crops and sowing conditions, and expand its application range. In other embodiments, the blowing part can also use conversion-type blowing and suction fans, centrifugal fans, axial flow fans and other equipment, which are not limited here. It can be understood that the driving fan is a common mechanical equipment in this field, and its specific structure and working principle are not described here.

[0045] In order to optimize the problem of inconvenient disassembly of the seed disturbance device, see Figure 3 The housing 10 is provided with a fixing ear 12 to facilitate the process of quickly installing and disassembling the seed disturbing device. Specifically, the fixing ear 12 includes a circular hole 121 and an arc-shaped card slot 122. The circular hole 121 is used for installing the housing 10. After installing the housing 10, the seed disturbing device is placed on the drive shaft of the seeder, the seed disturbing device is rotated, and the arc-shaped card slot 122 is rotated to the pre-fixed fixing rod, so that the seed disturbing device can be quickly installed and fixed. In addition, the housing 10 is provided with a mounting hole 13, which can be bolted to the connecting plate 21, thereby improving the disassembly efficiency.

[0046] See also Figure 4 Further, the bottom of the connecting plate 21 extends downward to form a mounting frame 23, the mounting frame 23 is rectangular, and the top of the airflow tube 24 is also rectangular. The mounting frame 23 can cooperate with the top pipe opening of the airflow tube 24, so as to have a higher sealing performance. In other embodiments, the mounting frame 23 can also be set to a circular shape, a triangular shape, etc., as long as the mounting frame 23 can be installed in coordination with the airflow tube 24. The specific shape is not limited here. In addition, the connecting plate 21 is provided with a fixing hole 213, and the fixing hole 213 can be detachably connected to the corresponding mounting hole 13 on the housing 10 by bolts.

[0047] Regarding the specific structure of the seed disturbance component 20. The seed disturbance component 20 also includes an air blowing pipe 22, which is arranged on the connecting plate 21 and located in the seed filling space 101. An air blowing channel 221 is formed inside the air blowing pipe 22, and the air blowing channel 221 runs through the connecting plate 21. One end of the air blowing channel 221 is connected to the seed filling space 101, and the other end of the air blowing channel 221 is connected to the air flow channel. The setting of the air blowing pipe 22 further enhances the effect of airflow seed disturbance. The airflow is directly guided into the seed filling space 101 by the air blowing pipe 22, which not only improves the coverage of the airflow, but also enhances the impact of the airflow, so that the disturbance of the seeds in the seed filling space 101 is more uniform and effective. The through-design of the air blowing channel 221 ensures that the airflow can be stably transmitted from the airflow channel to the seed filling space 101, effectively avoiding the loss and interference of the airflow during the transmission process, and improving the utilization efficiency of the airflow. In addition, the introduction of the air blowing tube 22 makes the seed disturbance component 20 more flexible and adjustable when facing different seed types and sowing requirements, and can adjust the direction and intensity of the airflow as needed, further optimizing the seed disturbance and seed filling effects, and enhancing the adaptability and practicality of the device.

[0048] Specifically, regarding the number of air blowing pipes 22, in the present embodiment, two air blowing pipes 22 are provided, and the two air blowing pipes 22 are symmetrically arranged on the connecting plate 21 with respect to the seed disturbing fan 31, so that the airflow in the air blowing pipes 22 can be evenly distributed at various positions of the seed filling space 101, so that the seed disturbing effect is more sufficient and uniform. In other embodiments, the number of air blowing pipes 22 can be set to one, three, etc. according to actual needs, which is not limited here.

[0049] Furthermore, a plurality of side blowing holes 222 are provided through the side wall of the air blowing tube 22, and the plurality of side blowing holes 222 are arranged at intervals along the extension direction of the air blowing tube 22. By providing a plurality of side blowing holes 222 on the side wall of the air blowing tube 22, airflow can be blown into the seed filling space 101 from multiple directions and positions, thereby forming a more uniform and three-dimensional airflow disturbance environment. The multi-point and multi-directional airflow disturbance can effectively prevent the accumulation and dead corners of seeds in the seed filling space 101, ensure that each seed can be fully disturbed and dispersed, and improve the uniform distribution of seeds on the seeding plate. In addition, the design of the spaced arrangement of the plurality of side blowing holes 222 along the extension direction of the air blowing tube 22 enables the airflow to form a series of continuous disturbance areas in the seed filling space 101, which not only enhances the coverage of the airflow, but also improves the continuity and stability of the airflow disturbance.

[0050] It is worth noting that in this embodiment, the sizes of the seed disturbance hole 211, the side blowing hole 222 and the opening of the air blowing tube 22 are all smaller than the size of the seeds, thereby preventing the seeds from flowing out of the openings and affecting the disturbance effect.

[0051] See also Figure 5, about the specific structure of the airflow tube 24. The airflow tube 24 is divided into a contraction section 241, a stable section 242 and a diffusion section 243 in the direction close to the connecting plate 21. The cross section of the contraction section 241 gradually decreases in the direction close to the connecting plate 21; the cross section size of the stable section 242 remains unchanged; the cross section of the diffusion section 243 gradually increases in the direction close to the connecting plate 21. First, the cross section of the contraction section 241 gradually decreases, so that the airflow entering the airflow tube 24 is accelerated when passing through the contraction section 241, forming a high-speed airflow. The high-speed airflow can effectively improve the disturbance effect of the seeds and ensure that the seeds are fully dispersed in the seed filling space 101. Subsequently, the airflow enters the stable section 242, the cross section remains unchanged, and the airflow velocity and pressure are stably and evenly distributed in the stable section 242, which is conducive to maintaining the continuity and stability of the airflow and further optimizing the seed disturbance effect. Finally, the cross section of the diffusion section 243 gradually increases, so that the airflow decelerates and diffuses in the diffusion section 243, forming a wider disturbance range. Through this gradually diffused airflow, every corner of the seed filling space 101 can be effectively covered, ensuring that all seeds are uniformly disturbed, preventing seeds from piling up and dead corners in certain areas, and further improving the seed filling effect and the uniformity of sowing. In this embodiment, the airflow tube 24 uses an existing venturi tube. The airflow tube 24 of the venturi tube structure improves the airflow control ability and seed disturbance effect of the seed disturbance device through reasonable airflow acceleration, stabilization and diffusion processes. It can be understood that the venturi tube is a common mechanical device in the field, and its specific structure and working principle are not described here.

[0052] For the specific structure of the seed disturbing fan 31, see Figure 2 and Figure 6 . The seed-disturbance fan 31 includes a first rotating shaft 312 and a seed-disturbance blade 311. The seed-disturbance blade 311 is spirally shaped and is arranged around the outer periphery of the first rotating shaft 312. The driving mechanism 32 is connected to the first rotating shaft 312, and the driving mechanism 32 can drive the seed-disturbance blade 311 to rotate around the first rotating shaft 312. The spiral seed-disturbance blade 311 can generate spiral airflow and mechanical disturbance when rotating, ensuring that the seeds are fully disturbed in the seed filling space 101, thereby avoiding the problems of seed accumulation and dead corners. Secondly, the spiral seed-disturbance blade 311 can push the seeds forward along the spiral path during rotation, making it easier for the seeds to contact the seeding holes, thereby improving the seed filling effect and filling rate. In other embodiments, the seed-disturbance blade 311 can also be configured as a plurality of blades arranged in a circular array on the connecting rod 321 along the circumference of the connecting rod 321. For example, three fan blades are arranged on the connecting rod 321 along the circumference of the connecting rod 321, and the angle between two adjacent fan blades is 120 degrees, etc., which is not limited here.

[0053] Specifically, the driving mechanism 32 is a connecting rod 321 and an air-driven fan 322. One end of the connecting rod 321 is located in the seed filling space 101 and is connected to the first rotating shaft 312. The other end of the connecting rod 321 passes through the connecting plate 21 and is located in the air flow channel. The other end of the connecting rod 321 is provided with an air-driven fan 322. The air-driven fan 322 is directly opposite to the blowing end of the blowing part. The blowing part can blow the air-driven fan 322 to rotate, thereby driving the connecting rod 321 and the seed-disturbing blades 311 to rotate. The air-driven fan 322 enables the seed-disturbing device to make full use of the existing airflow resources. The airflow generated by the blowing part directly drives the air-driven fan 3221 to rotate, thereby driving the connecting rod 321 and the seed-disturbing blades 311 to rotate. Thereby, the driving mechanism 32 is simplified, the use of additional electric or mechanical driving devices is avoided, and the overall efficiency and reliability of the seed-disturbing device are improved. Secondly, the design of the air-driven blade 3221 facing the blowing part ensures that the airflow can act on the air-driven blade 3221 in a concentrated and efficient manner, generating sufficient driving force to drive the seed-disturbance blade 311 to rotate, which not only ensures the stable operation of the seed-disturbance blade 311, but also forms a continuous and uniform disturbance effect in the seed-filling space 101, avoiding the accumulation and dead corner problems of seeds, and further improving the seed-filling effect and seed-filling rate. In addition, one end of the connecting rod 321 is located in the seed-filling space 101 and is connected to the seed-disturbance fan 31, while the other end passes through the connecting plate 21 and is located in the airflow channel, ensuring that the airflow can smoothly transmit the driving force, making the structure of the entire seed-disturbance device more compact and efficient. The self-driving function of the air-driven blade 3221 not only reduces the maintenance cost, but also improves the service life and operation stability of the device. In other embodiments, the driving mechanism 32 can also be configured as a driving motor, and the motor shaft of the driving motor is connected to the connecting rod 321. The motor shaft rotates to drive the connecting rod 321 and the seed-disturbing fan blades 311 to rotate synchronously, which is not elaborated here.

[0054] Specifically, one end of the first rotating shaft 312 is fixedly connected to the seed disturbing blade 311. The fixed connection design ensures the stability and reliability of the seed disturbing blade 311 during rotation, avoids the seed disturbing blade 311 from loosening or falling off, and improves the service life and working efficiency of the seed disturbing device. The outer circumference of the other end of the first rotating shaft 312 is provided with a thread, and the first rotating shaft 312 is threadedly connected to the connecting rod 321, so as to facilitate assembly, transportation, maintenance and replacement.

[0055] The air-driven fan 322 includes a second rotating shaft 3222 and air-driven blades 3221. The air-driven blades 3221 are spirally shaped and are wound around the outer circumference of the second rotating shaft 3222. The driving mechanism 32 is connected to the first rotating shaft 312. One end of the second rotating shaft 3222 is fixedly connected to the air-driven blades 3221. A thread is provided on the outer circumference of the other end of the second rotating shaft 3222. The second rotating shaft 3222 is threadedly connected to the connecting rod 321. In order to facilitate material acquisition and processing, the structure and size of the air-driven blades 311 and the air-driven blades 3221 are the same.

[0056] It is worth noting that the installation position of the air-driven fan 322 is located at the stable section 242 of the airflow tube 24 . According to the Venturi theory, the airflow here is the largest, which is more conducive to the rotation of the air-driven fan 322 .

[0057] Furthermore, in order to prevent the connecting rod 321 from sliding along the connecting plate 21, thereby affecting the disturbance effect, a limiting boss 313 is sleeved on the first rotating shaft 312, and the limiting boss 313 can abut against the connecting plate 21, thereby preventing the first rotating shaft 312 from sliding along the connecting plate 21. In addition, a connecting hole 212 is further provided on the connecting plate 21, and a first bearing 25 is provided in the connecting hole 212. The first rotating shaft 312 passes through the connecting hole 212 and cooperates with the first bearing 25.

[0058] In the present embodiment, the seed disturbance device further includes a flange 40 and a sealing gasket 50. The flange 40 is disposed between the connecting plate 21 and the contraction section 241. The connecting plate 21 and the contraction section 241 can be connected by the matching connection of the flange 40 and the airflow tube 24, and the sealing gasket 50 is disposed between the flange 40 and the airflow tube 24, so as to ensure the air tightness of the device. The flange 40 is a common mechanical device in the art, and its specific structure and working principle are not described in detail here. In the present embodiment, the sealing gasket 50 is a rubber pad, which has a good sealing effect and a certain elastic force, and can play a shock-absorbing effect, thereby protecting the equipment. In other embodiments, the sealing gasket 50 can also be a silicone pad, an asbestos pad, a metal pad, etc., which are not limited here.

[0059] Further, see Figure 7A fixing frame 33 is provided on one side of the connecting rod 321 near the air-driven fan 322. The fixing frame 33 includes a support arm 331 and a support plate 332. Four support arms 331 are provided, and the four support arms 331 are arranged in a cross pattern. One end of the support arm 331 is connected to the inner wall of the airflow channel, and the other end of the support arm 331 is connected to the support plate 332. A placement hole 333 is provided in the center of the support plate 332, and the connecting rod 321 is passed through the placement hole 333. The fixing frame 33 provides reliable support for the connecting rod 321, avoiding the problem of unstable operation caused by vibration or deviation of the connecting rod 321 during airflow driving. The design of the four support arms 331 arranged in a cross pattern enables the fixing frame 33 to evenly distribute the force, improves the balance and stability of the overall structure, and ensures the stability of the connecting rod 321 and the air-driven fan blades 3221 in efficient operation. One end of the support arm 331 is connected to the inner wall of the airflow channel, and the other end is connected to the support plate 332, so as to effectively transfer the structural strength of the inner wall of the airflow channel to the connecting rod 321, further enhancing the supporting effect of the connecting rod 321. The combination of the support arm 331 and the support plate 332 enables the fixing frame 33 to form a solid frame structure, which not only improves the anti-seismic and anti-impact capabilities of the seed disturbing device, but also reduces the wear and damage caused by vibration and impact, and improves the service life of the device. In addition, the connecting rod 321 is penetrated in the placement hole 333, ensuring the coaxial alignment of the air-driven blade 3221 and the connecting rod 321, reducing the problems of unstable operation and reduced efficiency caused by axial deviation. This design also enables the air-driven blade 3221 to maintain the optimal working angle and airflow direction when rotating, thereby improving the efficiency of airflow drive and the seed disturbing effect.

[0060] In order to prevent the connecting rod 321 from sliding downward in the axial direction under the action of gravity and affecting the seed disturbance process, a positioning block 323 is provided on the outer periphery of the connecting rod 321. The positioning block 323 can abut against the support plate 332, thereby limiting the axial movement of the connecting rod 321 and realizing the positioning of the connecting rod 321. The specific position of the positioning block 323 needs to be adjusted according to actual conditions and is not limited here.

[0061] Furthermore, a second bearing 34 is provided in the placement hole 333, and the second bearing 34 is coaxially arranged with the placement hole 333, and the second bearing 34 can be sleeved on the connecting rod 321. The second bearing 34 provides additional support and guidance for the connecting rod 321, ensuring that the connecting rod 321 always remains on the correct axis during the rotation process, avoiding vibration and unstable operation problems caused by axial deviation. The sleeve of the second bearing 34 effectively reduces the friction and wear of the connecting rod 321 during rotation, and improves the service life and reliability of the device. In addition, the second bearing 34 can effectively absorb and disperse the radial and axial forces generated by the connecting rod 321 during the rotation process, reduce the impact and pressure of these forces on the support plate 332 and the support arm 331, and extend the service life of each component of the device.
