Description

Technical Field

[0001] The present invention relates to an agricultural sowing machine, in particular to a garlic directional seeding device, a directional seeding system, and a seeder comprising the directional seeding device or system. Background Art

[0002] Garlic planting requires that the bulbs face upward. The planting process involves three key technologies: single-seed retrieval, directional adjustment and transport, and directional planting into the soil. While directional planting into the soil has been addressed in patent applications such as 2019102931960 and 2019106539954, single-seed retrieval and directional adjustment and transport remain bottlenecks in mechanized garlic planting, hindering the widespread adoption of garlic sowing machinery. The seamless integration of these three steps, single-seed retrieval, directional adjustment and transport, and directional planting into the soil, has also, to some extent, hindered the development of mechanized directional garlic planting. Currently, garlic sowing machinery lacks control over the orientation of the garlic's spine. This inability to control the orientation of the garlic leaves after emergence from the soil during sowing impacts subsequent growth, stalk extraction, and harvesting. This also reduces the planting density per unit area, which in turn affects garlic yield.

[0003] At present, there are two types of garlic single-grain seed extraction: mechanical and air-suction. For example, patent application number 2018211088185 uses a seeding spoon installed on a mechanical transmission chain. Due to the large size differences of garlic seeds and mechanical vibrations, over-seeding or missed seeding often occurs, and the reliability of single-grain seed extraction is insufficient. The air-suction technical solution, such as patent application number 2014105842186, has achieved a technological breakthrough in single-grain seed extraction, but it is sprayed into the conveying pipe through ventilation, which has a complex structure, a long time to complete the seeding, and low efficiency. For example, the technical solution with patent application number 2019103468571 installs the image processing and direction adjustment device on the air-suction centering disk. Since the image processing and direction adjustment time are relatively long, the directional seeding efficiency is low, and it is not suitable for high-speed directional sowing.

[0004] Currently, garlic directional adjustment and transmission mainly use mechanical, water-based, and visual systems. Mechanical methods are fast but lack accuracy, making them difficult to meet planting requirements. Water-based methods are bulky, with low efficiency and accuracy. Visual systems offer high accuracy for garlic directional adjustment, but are limited by the performance of processing chips and the complexity of the adjustment mechanism. They are effective at low speeds and unsuitable for high-speed directional seeding. Directional transmission generally uses pipes or troughs, some relying on the garlic's own gravity and others on airflow. These methods are inefficient and difficult to precisely control, impacting the efficiency and effectiveness of directional seeding. Summary of the Invention

[0005] The purpose of the present invention is to solve the technical problems of low precision, insufficient reliability and inability to adapt to high-speed directional seeding in a garlic single seed removal and directional adjustment transmission device, and to provide a garlic directional seeding device and system with high efficiency, strong versatility, precise controllable transmission process and suitable for high-speed planting, as well as a seeding machine using the device or system.

[0006] To solve the above problems, the technical solution adopted by the present invention is: a garlic directional seeding device, including a seed tray for sucking garlic seeds individually and preliminarily orienting them, a vision system installed near the seed tray for obtaining directional information of the garlic seeds and driving the garlic seeds to adjust their orientation based on the obtained information, and a universal transmission device for receiving the garlic seeds fed by the seed tray and actively transporting the garlic seeds to a set position in a controllable manner.

[0007] The seed tray of the present invention comprises a circular disk with multiple seed slots on its edge for initially orienting and protecting garlic seeds. Each seed slot houses a resilient suction nozzle for absorbing the garlic seeds. One end of the nozzle is mounted at the bottom of the seed slot and the other end has a nozzle opening. An air intake channel is located in the center of the nozzle, communicating with an air source through the inner cavity of the circular disk. This allows the nozzle to absorb individual garlic seeds as the circular disk rotates. After absorbing the garlic seeds, the nozzle contracts and shortens along its central axis under the action of air pressure. A greater pressure differential increases the contraction force, shortening the nozzle. The nozzle retracts into the seed slot, initially adjusting the orientation of the garlic seeds within the constraints of the slot. When the pressure differential between the inside and outside of the nozzle decreases, the nozzle begins to extend. Once the pressure differential decreases to a certain level, the nozzle releases the absorbed garlic seeds. The nozzle returns to its normal position until the pressure differential between the inside and outside equalizes, allowing the next seeding operation to begin.

[0008] Furthermore, the orientation is determined as a first direction or a second direction, where the first direction refers to the orientation of the garlic bulb; the second direction refers to the direction of the garlic bulb's dorsal line relative to the bulb's axis. The preliminary orientation involves determining the first direction as one direction or its opposite direction, while simultaneously determining the second direction as the set direction. Determining the second direction ensures that the garlic leaves, after emerging from the soil, face a consistent orientation, receiving more sunlight, increasing the planting density per unit area, and facilitating subsequent mechanized operations such as garlic stalk extraction and harvesting.

[0009] The seed taking groove of the present invention is V-shaped or U-shaped or other shapes that can match the shape of the garlic seeds, so that the garlic seeds can adjust their direction during the process of moving into the seed taking groove after being adsorbed, and the garlic seeds can be protected.

[0010] The suction nozzle of the present invention has a suction nozzle opening that matches the shape of garlic, has elasticity, and is made of a soft material with certain elasticity, such as rubber or latex.

[0011] The vision system of the present invention includes at least one image acquisition device that captures orientation information of garlic seeds within a seed collection slot and transmits this qualitative information to an image processing system. The image processing system determines the orientation of the garlic bulbs and, based on the determination, adjusts the garlic seeds, whose orientation information has been captured, to a predetermined orientation during subsequent transmission. Furthermore, the image processing system adjusts the air pressure within the seed collection tray based on the orientation information within the seed collection slot, ensuring more directional seed collection from the tray.

[0012] The universal transmission device of the present invention includes a universal transmission chain capable of transmitting in three-dimensional space, and a plurality of transport boxes that cooperate with the universal transmission chain and can independently transport single garlic seeds. Each transport box protects the garlic seeds fed into the seed tray to prevent the garlic seeds from changing direction relative to the transport box during transportation to a set position.

[0013] Furthermore, the transport box can change its position relative to the universal transmission chain as needed. When the direction of the garlic seeds needs to be adjusted, the transport box and the garlic seeds it carries are rotated relative to the moving direction of the universal transmission chain.

[0014] To improve the efficiency and reliability of directional seeding and meet the needs of high-speed directional seeding, multiple directional seeding devices are connected in parallel to form a directional seeding system with a single output. This directional seeding system provides a directional seed source for a seeding device that is planted in the soil. At this time, the coordination between the universal transmission chain and the transport box of each directional seeding device can be separated or merged as needed. During the merging process, the transport box to be merged is separated from the universal transmission chain that drove its movement before the merger and reunited with the universal transmission chain that drives its movement after the merger. In this way, after the multiple directional seeding devices are merged, a system with a single directional output is formed, which improves seeding efficiency.

[0015] A seeder using the directional seeding device or directional seeding system of the present invention comprises a power locomotive, a frame mounted on the power locomotive, a plurality of seeding devices mounted on the frame, a plurality of the directional seeding devices or directional seeding systems cooperating with the seeding devices, an auxiliary device cooperating with the seeding devices, a transmission device for transmitting power, and a trough for containing garlic seeds.

[0016] The auxiliary device of the present invention is a device that completes one or more of fertilizing, watering, spraying, laying ground film, drilling or other auxiliary planting operations.

[0017] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0018] 1) The present invention adopts an air-suction seed tray provided with a seed taking groove and a suction nozzle mechanism. While accurately sucking a single garlic seed, the bulb bud direction is preliminarily adjusted to prepare for further direction adjustment, thereby improving the efficiency and accuracy of determining the bulb bud direction. At the same time, the second direction of the garlic seed is adjusted by contraction of the suction nozzle and restriction of the seed taking groove, so that the garlic leaves are oriented in the same direction after being unearthed, providing convenience for subsequent growth and harvesting, improving the accuracy of garlic sowing, filling the gap in second-direction directional mechanized planting, increasing the sowing density per unit area, and improving the yield.

[0019] 2) The present invention obtains the orientation information on the seed tray through the visual system, which maximizes the time for image processing and orientation adjustment, thereby improving the efficiency of directional seeding.

[0020] 3) The present invention utilizes the characteristic of the universal transmission chain that it can freely transmit in three-dimensional directions in space, thereby increasing the flexibility and adaptability of directional transmission.

[0021] 4) The present invention adopts a structure in which the transport box and the universal transmission chain can be separated and merged as needed, so that multiple directional seeding devices are connected in parallel into a directional seeding system, overcoming the problem of limited efficiency of a single directional seeding device, greatly improving the reliability of directional seeding, and providing convenience for high-speed directional planting.

[0022] 5) In addition to being used for directional planting of garlic, the technical solution of the present invention can also be used for directional planting of large seeds such as corn, sunflower, and beans, as well as non-directional planting of cotton. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The technical solution of the present invention is further described in detail below through the accompanying drawings and examples. Although the drawings show exemplary embodiments of the present disclosure, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Instead, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0039] like Figures 1 to 12As shown, the technical solution adopted by the present invention is: a garlic directional seeding device 1, including a seed tray 1-1 for sucking garlic seeds individually and preliminarily orienting them, a visual system 1-2 installed near the seed tray 1-1 for obtaining directional information of the garlic seeds and driving the garlic seeds to adjust their orientation based on the obtained information, and a universal transmission device 1-3 for receiving the garlic seeds fed by the seed tray 1-1 and actively transporting the garlic seeds to a set position in a process-controlled manner.

[0040] like Figure 3 、 Figure 4 As shown, the seed tray 1-1 of the present invention comprises a circular disk 1-11. The edge of the circular disk 1-11 is provided with a plurality of seed slots 1-12 for initially orienting and protecting the garlic seeds. Each seed slot 1-12 is fitted with a resilient suction nozzle 1-13 for sucking individual garlic seeds. One end of the suction nozzle 1-13 is mounted at the bottom of the seed slot 1-12, and the other end is provided with a suction nozzle opening 1-131. An air intake channel 1-132 is provided in the center of the suction nozzle 1-13 for air circulation. The suction channel 1-132 is connected to the air source 1-4 through the circular disk 1-11, enabling the suction nozzle 1-13 to suck individual garlic seeds as the circular disk 1-11 rotates. After the suction nozzle 1-13 sucks the garlic seeds, under the action of air pressure, the suction nozzle 1-13 shrinks and shortens along the middle axis direction. The greater the air pressure difference, the greater the contraction force, and the shorter the suction nozzle 1-13 shrinks. The suction nozzle 1-13 shrinks and enters the seed taking groove 1-12. Under the restriction of the seed taking groove 1-12, the direction of the garlic seeds is preliminarily adjusted; when the pressure difference between the inside and outside of the suction nozzle 1-13 decreases, the suction nozzle 1-13 begins to extend, and releases the sucked garlic seeds after the pressure difference is small to a certain extent. Until the pressure difference between the inside and outside is equal, the suction nozzle 1-13 returns to a natural state and starts the next seed taking.

[0041] like Figure 5 As shown, the orientation is determined by determining a first direction x or a second direction y, where the first direction x refers to the orientation of the garlic bulb; the second direction y refers to the direction of the garlic bulb's dorsal line relative to the bulb's axis. The initial orientation involves determining the first direction x as one direction or its opposite direction, while simultaneously determining the second direction y as a set direction. Determining the second direction y ensures that the garlic leaves are oriented in a consistent manner after emergence, allowing for more sunlight exposure, increasing planting density per unit area, and facilitating subsequent mechanized operations such as garlic stalk extraction and harvesting.

[0042] As a preferred embodiment of the present invention, the seed retrieval groove 1-12 is V-shaped, U-shaped, or other shape that matches the outer shape of the garlic seeds. This allows the garlic seeds to be initially oriented as they move into the seed retrieval groove 1-12 after adsorption, thereby protecting the garlic seeds. The centerline of the seed retrieval groove 1-12 and the axis of the disk 1-11 are parallel to each other or form a certain angle. When the angle is formed, the seed retrieval disc is thinner, which facilitates the absorption of the garlic seeds.

[0043] The suction nozzle 1-13 and the suction nozzle opening 1-131 of the present invention are matched with the shape of garlic. The suction nozzle 1-13 has elasticity and is made of a soft material with certain elasticity, such as rubber or latex.

[0044] As a preferred solution of the present invention, the suction nozzle 1-13 is installed at one end of the seed removal groove 1-12 and is provided with a pressure-stabilizing air valve 1-134, which is used to stabilize the air pressure in the inner cavity of the seed removal plate 1-1 to prevent the change of the internal air pressure of one suction nozzle 1-13 from affecting the operation of other suction nozzles 1-13.

[0045] like Figure 2 As shown, the visual system 1-2 of the present invention includes at least one image acquisition device 1-21, such as a camera or laser radar, for acquiring orientation information of garlic seeds within the seed retrieval slot 1-12. This image acquisition device 1-21 transmits the acquired qualitative information to an image processing system 1-22. The image processing system 1-22 determines the orientation of the garlic bulbs and, based on this determination, drives the garlic seeds, whose orientation information has been acquired, to adjust to a predetermined orientation during subsequent transmission. Furthermore, the image processing system 1-22 adjusts the pressure of the air source 1-4 based on the orientation information within the seed retrieval slot 1-12, thereby ensuring that the seed retrieval tray 1-1 can more effectively align the seeds.

[0046] like Figure 2 As shown, the universal transmission device 1-3 of the present invention includes a universal transmission chain 1-31 capable of transmitting in three-dimensional space, and a plurality of transport boxes 1-32 that cooperate with the universal transmission chain 1-31 and can independently transport single garlic seeds. The plurality of transport boxes 1-32 are spaced a certain distance apart to prevent interference with each other. Each transport box 1-32 independently protects the garlic seeds fed into the seed tray 1-1 to prevent the garlic seeds from changing direction relative to the transport box 1-32 during transportation to the set position.

[0047] As a preferred embodiment of the present invention, the universal transmission device 1-3 is provided with a release mechanism 1-323 for changing the air pressure in the suction nozzle 1-13, and the seed removal tray 1-1 is provided with a vent valve 1-133 that cooperates with the release mechanism 1-323. When the transport box 1-32 moves to the corresponding seed removal slot 1-31, the release mechanism 1-323 opens the vent valve 1-133, so that the air pressure in the suction nozzle 1-13 is instantly reduced, and the garlic seeds at the suction nozzle mouth 1-131 are sent into the transport box 1-32.

[0048] As a preferred embodiment of the present invention, the distance between the plurality of seed taking slots 1-12 on the seed taking tray 1-1 corresponds to the distance between the transport boxes 1-32 on the universal transmission chain 1-31, so that each transport box 1-32 can receive garlic seeds in turn, and with the assistance of the visual system 1-2, the situation where no single garlic seed is successfully obtained in the seed taking slot 1-12 can be skipped.

[0049] As a preferred embodiment of the present invention, the visual system 1-2 further includes at least one image acquisition device II1-211, such as a camera, a laser radar, etc., arranged near the universal transmission device 1-3, for acquiring orientation information of the garlic in the transport box 1-32, and transmitting the orientation information to the image processing system 1-22 to confirm the orientation of the garlic seeds, and further adjust the direction of the garlic seeds through the orientation execution device 1-23 during the transmission process according to the image processing results.

[0050] As a preferred embodiment of the present invention, the transport box 1-32 can change its position relative to the universal transmission chain 1-31 as needed. When the direction of the garlic seeds needs to be adjusted, the transport box 1-32 and the garlic seeds it carries are rotated relative to the moving direction of the universal transmission chain 1-31.

[0051] As a preferred embodiment of the present invention, the universal transmission chain 1-31 includes a closed flexible rope 1-311, such as a steel wire rope, and a combination 1-312 fixedly installed on the rope 1-311 at a certain distance and cooperating with the transport box 1-32.

[0052] As another preferred embodiment of the present invention, the universal transmission chain 1-31 is a universal chain, including a plurality of inner universal joints 1-313, a plurality of outer universal joints 1-314 cooperating with the inner universal joints 1-313, and a pin 1-315. The inner universal joints 1-313 and the outer universal joints 1-314 are connected at intervals by the pin 1-315, and are connected end to end to form a closed chain, as well as a combination 1-312 uniformly provided on the outer universal joints or uniformly provided on the inner universal joints 1-313 to cooperate with the transport box 1-32.

[0053] As a preferred embodiment of the present invention, the transport box 1-32 includes a box body 1-321 capable of fixing garlic seeds, and a mounting seat 1-322 installed on the box body 1-321 and cooperating with the coupling body 1-312 on the universal transmission chain 1-31.

[0054] As a preferred embodiment of the present invention, the box body 1-321 of the transport box 1-32 is provided with a slot 1-3211 for placing garlic seeds, and an elastic mechanism 1-3212 for fixing the garlic seeds, such as a spring sheet or an air bag, which is convenient for opening or closing and can fix the garlic seeds.

[0055] As a preferred solution of the present invention, at least one of the combination 1-312 or the transport box 1-32 is magnetic and can be firmly attracted together during transportation. When the combination 1-312 needs to be separated from the mounting seat 1-322, it can be separated smoothly without damage to facilitate directional adjustment or orderly merging of multiple universal transmission devices 1-3.

[0056] As a preferred embodiment of the present invention, the garlic directional seeding device 1 further includes a trough 1-5 for containing garlic seeds.

[0057] In order to improve the efficiency and reliability of directional seeding and to meet the needs of high-speed directional seeding, multiple directional seeding devices 1 are connected in parallel to form a directional seeding system 2. The directional seeding system 2 provides a directional seeding source for a sowing device 3-3 planted in the soil. At this time, the coordination state of the universal transmission chain 1-31 and the transport box 1-32 of each directional seeding device 1 can be separated or merged as needed. The combination 1-312 on the universal transmission chain 1-31 should be staggered a certain distance from each other to prevent the transport box 1-32 from colliding or blocking the merging channel during merging. During the merging process, the transport box 1-32 to be merged is separated from the universal transmission chain 1-31b that drives it to move before the merger, and is combined with the universal transmission chain 1-31a that drives it to move after the merger. In this way, after the multiple directional seeding devices 1 are merged, a directional seeding system 2 is finally formed, which improves the seeding efficiency. After completing the planting task, the transport boxes 1-32 must be distributed to each universal transmission chain 1-31 in an orderly manner through the distribution guide rail 1-332 under the action of the distribution controller 1-333.

[0058] As a preferred embodiment of the present invention, the universal transmission device 1-3 further includes a transport guide rail 1-33 for restraining the universal transmission chain 1-31 or the transport box 1-32. When multiple universal transmission devices 1-3 need to be combined, a Y-shaped combining guide rail 1-331 is provided at the combined location. The transport guide rail 1-33 is provided with an opening and closing mechanism for the elastic mechanism 1-3212 on the transport box. The elastic mechanism 1-3212 closes after the transport box 1-32 receives the garlic seeds, and opens when the garlic seeds need to be released.

[0059] As a preferred solution of the present invention, the directional seeding system 2 further includes a trough for containing garlic seeds.

[0060] A seeder 3 using the directional seeding device 1 or directional seeding system 2 described in the present invention includes a power locomotive 3-1, a frame 3-2 installed on the power locomotive, a plurality of seeding devices 3-3 installed on the frame, a plurality of the directional seeding devices 1 or directional seeding systems 2 cooperating with the seeding devices 3-3, an auxiliary device 3-4 cooperating with the seeding devices 3-3, and a transmission device 3-5 for transmitting kinetic energy.

[0061] The auxiliary devices 3-4 described in the present invention are devices for completing one or more of fertilizing, watering, spraying, laying ground film, drilling or other auxiliary planting operations.

[0062] The above examples are intended only to illustrate the content of the present invention and are not intended to limit the scope of the present invention. They are not limited to the directional planting of garlic and are equally applicable to other crops requiring directional planting, such as corn and beans, as well as to crops that are not directional. Any changes or combinations of the components in the above examples made by those skilled in the art are within the scope of the present invention. Improvements and substitutions made by those skilled in the art within the scope of the present invention are also within the scope of the present invention.

The garlic directional seeding system according to claim 6, characterized in that: The coordination state between the universal transmission chain and the transport box of each directional seeding device can be separated or merged as needed. A Y-shaped merging guide rail is provided at the merging point. During the merging process, the merged transport box is separated from the universal transmission chain that drives it to move before the merging, and is combined with the universal transmission chain that drives it to move after the merging. In this way, a plurality of the directional seeding devices are finally merged to form a directional seeding system. After completing the planting task, the transport boxes must be distributed to each universal transmission chain in an orderly manner through the distribution guide rail under the action of the distribution controller. The combinations on the universal transmission chain must be staggered at a certain distance from each other to prevent the transport boxes from colliding or blocking the merging channel during merging.
