Description

Technical Field

[0001] This invention relates to the field of agricultural seeding machinery technology, specifically to a garlic seeding and planting device. Background Technology

[0002] As an important economic crop, the quality of garlic planting directly affects the subsequent emergence rate and yield. Traditional garlic planting relies heavily on manual labor, which has problems such as low efficiency, high labor intensity, and unstable uprightness.

[0003] Garlic planting machinery suffers from problems such as missed planting and uncertain bulb orientation, making it difficult to meet the agronomical requirements of planting one seed per hole with the bulb facing upwards. This results in poor planting quality and reduced garlic yield when using garlic planting machinery. Some garlic planting devices use duckbill devices for precise insertion, which can improve the upright planting rate, but has obvious drawbacks: limited operating speed, as the duckbill device needs to complete the mechanical action of "insertion-opening-releasing-pulling out", and the travel speed is usually no more than 3-5 km / h. Too fast a speed can easily cause component deformation and tearing of the planting furrow; demanding soil conditions, difficult to insert in dry and hard soil, easy to cause blockage in wet and sticky soil, and stubble can also become entangled and obstruct the process; complex structure and high failure rate, as connecting rods, cams and other components are easily jammed or worn by soil, resulting in high maintenance costs; mechanical compression can easily damage garlic seeds, poor flexibility in adjusting row and plant spacing, and high power consumption.

[0004] A search revealed a Chinese patent (CN111527842B) disclosing a garlic planter, comprising a planting box, a garlic-collecting unit, a garlic-receiving slide, a garlic tip-turning mechanism, and a planting assembly. All components are mounted on a frame. A transmission unit is also included to drive the garlic-collecting unit and the planting assembly. This invention uses a tractor or other tractor to tow the frame, with the wheels driving the garlic-collecting unit to sequentially transport garlic seeds from the planting box to the garlic tip-turning mechanism and the planting assembly. Finally, the furrow opener assembly delivers the seeds into the soil, significantly improving the mechanization of garlic planting. Furthermore, the garlic tip-turning mechanism effectively identifies and adjusts the direction of the garlic tips, solving the technical challenge of ensuring garlic tips face upwards during mechanized garlic cultivation.

[0005] The aforementioned application uses an industrial camera to identify and adjust the orientation of garlic tips, but this is not combined with the function of screening for defective seeds. This results in a single function of the equipment, which cannot simultaneously solve the two core problems of the influence of defective seeds and the deviation of garlic tip orientation. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies and solve the aforementioned technical problems, this invention proposes a garlic planting device.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: a garlic planting device, comprising a frame, a planting box fixed inside the frame for holding garlic seeds, a garlic picking unit disposed on the planting box for taking out garlic seeds from the planting box, an adjustment unit disposed below the garlic picking unit for adjusting the orientation of the garlic seeds, a detection and screening unit disposed inside the adjustment unit for identifying and screening the taken-out garlic seeds, a feeding unit disposed at the bottom of the adjustment unit for planting garlic, and a hole-opening component disposed in front of the feeding unit for opening holes to place garlic seeds. The hole-opening component is slidably connected with the feeding unit when inserted into the soil to open holes, and quickly resets after the holes are opened and the component rises away from the soil.

[0008] By adopting the above technical solution, four sets of electric push cylinders are fixed at the bottom of the frame, and movable wheels are fixed at the bottom of the electric push cylinders. The height of the frame is adjusted by extending the electric push cylinders, so that the adjustment chamber is in contact with the ground during sowing, and is higher than the ground after sowing is completed.

[0009] The feeding unit includes a feeding chamber fixed to the bottom of the frame. The feeding chamber has a corresponding mounting cavity corresponding to the adjustment unit. The front side of the mounting cavity has two sliding grooves, one upper and one lower. The cavity opening component includes a slider made of ferromagnetic material that is slidably installed in the upper sliding groove. A cylinder is fixed at the center of the slider, and a cavity opener is fixed at the driving end of the cylinder. An electromagnet is fixed on the upper surface of the front side of the mounting cavity.

[0010] The cavity opener includes a motor, a drill bit is fixedly mounted on the drive end of the motor, and a shovel plate is fixedly mounted on the front end of the plurality of feeding chambers.

[0011] The installation cavity is equipped with a second motor, and the drive end of the second motor is equipped with several garlic feeding buckets. The upper side of the installation cavity is provided with a feed inlet corresponding to the adjustment unit, and the lower side of the installation cavity is provided with a discharge outlet. Both the feed inlet and the discharge outlet are located on the moving trajectory of the garlic feeding buckets.

[0012] The surface of the garlic feeding hopper has several slots. The outer side of the slots is provided with mounting ears that are fixedly connected to the garlic feeding hopper. The interior of the mounting ears is rotatably connected to a lower pressure plate via a torsion spring shaft. A magnetic block is embedded and fixedly mounted on the bottom end of the lower pressure plate facing the garlic feeding hopper. A magnetic ring is fixedly mounted on the inner bottom wall of the mounting cavity and is coaxially arranged with the discharge port. The magnetic ring and the magnetic block are magnetically attracted to each other on opposite sides.

[0013] A buffer chamber is slidably disposed above the feed inlet. An elastic telescopic rod is fixed between the outer side of the buffer chamber and the discharge chamber. Several grooves are formed on the inner wall of the buffer chamber. A buffer plate is rotatably connected to the inside of the grooves through a torsion spring shaft. A buffer pad is fixed on the upper surface of the buffer plate. A rotating disk is fixed through the drive end of the motor and inserted into the discharge chamber. A protrusion is fixed on the top of the rotating disk. An inclined block is fixed on the outer wall of the buffer chamber at the rotation trajectory of the protrusion.

[0014] The garlic-picking unit includes several garlic-picking discs connected by hollow pipes. A motor is fixedly mounted on the outer wall of the frame. The drive end of the motor is fixedly connected to one end of the hollow pipe, and the other end of the hollow pipe passes through the frame and is connected to a negative pressure device. The surface of the garlic-picking disc has multiple planes, and adsorption holes are opened on the planes. Several sealing plates made of ferromagnetic material are set on the corresponding planes inside the garlic-picking disc. An elastic telescopic rod is fixed between the sealing plate and the garlic-picking disc.

[0015] The adjustment unit includes an adjustment chamber fixedly connected to the frame. The bottom of the adjustment chamber is open and a seed guide tube is fixedly connected thereto. A rotating cylinder with a single-end opening is rotatably connected inside the adjustment chamber. Several separation plates arranged in a ring are fixedly provided on the outer wall of the rotating cylinder. A motor is fixedly provided on the outer wall of the adjustment chamber. The drive end of the motor is fixedly connected to the rotating cylinder.

[0016] The surface of the rotating cylinder and the separating plates are alternately provided with an opening. The inner end of the rotating cylinder is rotatably provided with a sorting cylinder that penetrates the adjustment chamber. One side of the sorting cylinder is provided with an opening, and the inner wall of the other side of the sorting cylinder is fixed with an inclined layer. The outer wall of the adjustment chamber is provided with a rotating device that drives the sorting cylinder to rotate.

[0017] The detection and screening unit includes a rotating frame and a motor five. The rotating frame is rotatably mounted inside the adjustment unit via a shaft. The motor five is fixedly mounted on the outside of the adjustment unit, and the drive end of the motor five is fixedly connected to the shaft of the rotating frame. A motor six is ​​fixedly mounted at the center of the rotating frame. A detection platform is fixedly mounted at the drive end of the motor six. An electromagnet two is embedded and fixedly mounted inside the detection platform, and a flexible pad is fixedly mounted at the top of the detection platform. An adjustable-angle detection device is installed on the side wall of the detection platform.

[0018] Working principle: During planting, garlic seeds are taken out of the planting box by the garlic-collecting unit and transported to the detection and screening unit. The detection and screening unit detects the size and quality of the garlic seeds, retains qualified garlic seeds and transports them to the adjustment unit. Unqualified garlic seeds such as oversized garlic, oversized garlic, double-clove garlic, broken garlic, moldy cloves, and shriveled cloves are screened out. The garlic seeds are adjusted by the adjustment unit so that they fall into the feeding unit with the garlic tip pointing upwards. When the device moves, the hole-opening component opens holes in the soil to form planting holes. Then, when the garlic seeds in the feeding unit move to the planting holes, they fall vertically into the planting holes, completing the automated planting of garlic seeds. The hole-opening component remains in sliding connection with the feeding unit when the device moves, so it can open holes in place. After opening the holes, it is fixed to the feeding unit, so that the hole-opening component does not affect the moving speed of the device when opening holes.

[0019] This invention provides a garlic planting device. It has the following beneficial effects: 1. This invention uses an industrial camera in the screening unit to achieve full-surface detection of garlic seeds without blind spots, accurately screening out unqualified garlic seeds such as those that are too small, too large, double-clove, broken, moldy, or shriveled. At the same time, the orientation of qualified garlic seeds can be adjusted by the adjustment unit to ensure that the garlic tip is facing upwards when planted. This not only avoids the impact of bad seeds on the germination rate, but also meets the agronomic requirement of "one seed per hole, with the scales facing upwards", significantly improving the quality and yield of garlic planting.

[0020] 2. This invention adopts an independent operating logic of "opening holes first and then planting". The hole-opening component achieves flexible switching between sliding and fixed connection through the cooperation of electromagnet and slider. When opening holes, it can work in place relative to the feeding unit without interfering with the overall movement rhythm of the device, breaking through the speed bottleneck of traditional duckbill devices. The rotary drill bit adopts a spiral tungsten steel cutter head, which can actively break up soil lumps and residues, reduce soil penetration resistance, adapt to various soil conditions such as dry and hard, wet and sticky, avoid blockage or component deformation, and greatly improve the stability of operation.

[0021] 3. The feeding unit of this invention is equipped with a buffer chamber and multiple sets of buffer plates to effectively offset the impact force of the falling garlic seeds and protect the integrity of the garlic seeds. The lower pressure plate of the garlic feeding hopper uses the synergistic effect of torsion spring and magnetic attraction to not interfere with the garlic seeds entering the hopper under normal conditions. When feeding, it accurately triggers the pressing action, which not only prevents the garlic seeds from sticking and getting stuck, but also compensates for the alignment error between the feeding port and the planting hole, ensuring that the garlic seeds fall accurately into the planting hole and improving the planting accuracy.

[0025] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see the appendix Figure 1 - Appendix Figure 2 This invention provides a garlic planting device, including a frame 1, a planting box 2 fixed inside the frame 1 for holding garlic seeds, a garlic picking unit 3 mounted on the planting box 2 for taking out garlic seeds from the planting box 2, an adjustment unit 4 mounted below the garlic picking unit 3 for adjusting the orientation of the garlic seeds, a detection and screening unit 5 mounted inside the adjustment unit 4 for identifying and screening the taken-out garlic seeds, a feeding unit 6 mounted at the bottom of the adjustment unit 4 for planting garlic, and a hole-opening component 7 mounted in front of the feeding unit 6 for opening holes to place garlic seeds. When the hole-opening component 7 is inserted into the soil to open holes, it maintains a sliding connection with the feeding unit 6, and after the hole is opened and it rises away from the soil, it quickly returns to its original position.

[0027] Specifically, during planting, garlic seeds are taken from the planting box 2 via the garlic-collecting unit 3 and transported to the detection and screening unit 5. The detection and screening unit 5 checks the size and quality of the garlic seeds, retaining qualified garlic seeds and transporting them to the adjustment unit 4. Unqualified garlic seeds, such as those that are too small, too large, double-clove, broken, moldy, or shriveled, are screened out. The garlic seeds are then adjusted by the adjustment unit 4 so that they fall into the feeding unit 6 with the tips pointing upwards. As the device moves, the hole-opening component 7 opens holes in the soil to form planting holes. Subsequently, when the garlic seeds in the feeding unit 6 move to the planting holes, they fall into the planting holes, completing the automated planting of garlic seeds. The hole-opening component 7 remains in sliding connection with the feeding unit 6 during the movement of the device. This allows for in-situ hole opening, followed by fixing to the feeding unit 6 after hole opening. This ensures that the hole-opening component 7 does not affect the device's movement speed during hole opening. Compared to the traditional duckbill device's continuous "insertion-opening-release-pulling" action mode, this garlic planting device adopts an independent "hole opening then planting" operation logic, offering significant advantages. The duckbill device needs to complete multiple mechanical actions synchronously with the device's movement, resulting in a strict limitation on its movement speed. Excessive speed can easily cause problems such as component deformation and tearing of the planting furrow. In contrast, the hole-opening component 7 and the feeding unit 6 of this device can flexibly switch between sliding and fixed connections. During hole opening, it can operate relatively in place relative to the feeding unit 6, without interfering with the overall movement rhythm of the device, significantly breaking through the speed bottleneck.

[0028] Please see the appendix Figure 2 - Appendix Figure 3The unloading unit 6 includes an unloading chamber 601 fixed to the bottom of the frame 1. The unloading chamber 601 has a corresponding mounting cavity 602 corresponding to the adjustment unit 4. The front side of the mounting cavity 602 has two sliding grooves, one upper and one lower. The cavity opening assembly 7 includes a slider 71 made of ferromagnetic material that is slidably installed in the upper sliding groove. A cylinder 72 is fixed at the center of the slider 71. A cavity opener 73 is fixed at the driving end of the cylinder 72. An electromagnet 74 is fixed on the upper front surface of the mounting cavity 602. The cylinder 72 can be replaced with other linear telescopic devices, such as an electric push cylinder or a hydraulic rod.

[0029] Specifically, when opening a planting hole, electromagnet 74 is turned off, and cylinder 72 extends to move the hole opener 73 downward into the soil to form a planting hole. At this time, due to the restriction of the soil, as the device moves, slider 71 moves along the moving chute to the rear and stops in place. After the hole is opened, cylinder 72 retracts to raise the hole opener 73 above the soil. Then, electromagnet 74 attracts slider 71 and quickly slides to the front of the chute to open the hole again. By repeating the above steps, multiple planting holes with relatively equal spacing are formed.

[0030] Please see the appendix Figure 2 - Appendix Figure 3 The hole opener 73 includes a motor 731 connected to a cylinder 72. A drill bit 732 is fixedly mounted on the drive end of the motor 731. A shovel plate 603 is fixedly mounted on the front end of the feeding chamber 601. The drill bit 732 is conical or cylindrical in shape and adopts a spiral tungsten carbide cutter head structure. The cutter head surface is provided with three equally spaced spiral chip removal grooves. The groove walls adopt an arc transition design, and the top of the cutter head is a conical pointed edge structure. The cutting edge is hardened by quenching. The spiral tungsten carbide drill bit 732 quickly breaks through the soil through the conical pointed edge. The spiral chip removal groove can promptly discharge broken soil debris along the groove body, and with the strip-shaped chip removal hole of the protective sleeve, it can effectively prevent soil from accumulating in the hole or sticking to the drill bit 732. Even in heavy clay soil, it can form a regular planting hole. The quenched and hardened cutting edge and tungsten steel material improve the wear resistance and hard-breaking ability of the drill bit 732. When facing obstacles such as small stones and crop residues in the soil, it is not easy for the cutting edge to break or the drill bit 732 to bend. Compared with the duckbill tool, which is prone to deformation and jamming due to obstacles, the operation stability is greatly improved.

[0031] Specifically, when opening a planting hole, the motor 731 drives the drill bit 732 to rotate and break up the ground to open the hole. The rotating drill bit 732 of this device can actively break up hard soil clumps and residues, greatly reducing the resistance to entering the soil. It can easily form regular planting holes in dry and hard soil, and also reduce soil adhesion in wet and sticky soil.

[0032] The shovel plate 603 is used to level the tilled soil when the device moves, so that the lower surface of the feeding chamber 601 can move in contact with the upper surface of the soil layer for sowing.

[0033] Please see the appendix Figure 3 The installation cavity 602 is equipped with a second motor 604. The drive end of the second motor 604 is equipped with several garlic feeding buckets 605. The upper side of the installation cavity 602 is provided with a feeding port 9 corresponding to the adjustment unit 4, and the lower side of the installation cavity 602 is provided with a discharging port 8. The feeding port 9 and the discharging port 8 are located on the moving trajectory of the garlic feeding buckets 605. The garlic feeding buckets 605 are provided with rectangular or circular storage spaces.

[0034] Specifically, the garlic seeds, after being adjusted in the adjustment unit 4, fall into the garlic feeding hopper 605 through the feed inlet 9. The garlic feeding hopper 605, which stores the garlic seeds, is rotated to the discharge port 8 by the rotation of the motor 2 604. When the device moves and the discharge port 8 coincides with the planting hole, the garlic seeds automatically fall into the planting hole through the discharge port 8.

[0035] Please see the appendix Figure 3 The surface of the garlic feeding hopper 605 has several slots. The outer side of the slots is provided with mounting ears 606 that are fixedly connected to the garlic feeding hopper 605. The interior of the mounting ears 606 is rotatably connected to the lower pressure plate 607 through a torsion spring shaft. A magnetic block 608 is embedded and fixedly installed at the bottom end of the lower pressure plate 607 facing the garlic feeding hopper 605. A magnetic ring 609 is fixedly installed on the inner bottom wall of the mounting cavity 602 and is coaxially arranged with the discharge port 8. The magnetic ring 609 and the magnetic block 608 are magnetically attracted to each other on opposite sides.

[0036] Specifically, the lower pressure plate 607 rotates upward via a torsion spring and abuts against the mounting ear 606 to maintain an upward tilt. It is located outside the garlic feeding hopper 605 to avoid affecting the garlic seeds falling into the garlic feeding hopper 605. When the garlic feeding hopper 605 rotates to the discharge port 8, the magnetic attraction of the magnetic ring 609 and the magnetic block 608 overcomes the torque of the torsion spring shaft, causing the lower pressure plate 607 to rotate downward and apply downward pressure to the garlic seeds in the garlic feeding hopper 605. This helps the garlic seeds to be discharged. It can also assist in pushing the garlic seeds into the planting hole when the device's movement trajectory is not straight and the discharge port 8 does not completely coincide with the planting hole.

[0037] The lower pressure plate 607 of this device, through the cooperation of torsion spring and magnetic attraction, maintains an upward tilted posture under normal conditions so as not to interfere with the garlic seed entering the hopper. It precisely triggers a downward pressing action at the feeding port 8, which not only avoids the risk of jamming in mechanical transmission, but also provides stable feeding power for garlic seed through flexible pressing. It effectively prevents the garlic seed from being stuck to the inner wall of the garlic feeding hopper 605 or from being unable to feed smoothly due to its own posture. Most importantly, when there is a slight deviation in the movement trajectory of the device or the feeding port 8 is not completely aligned with the planting hole, the active pushing function of the lower pressure plate 607 can compensate for the alignment error and ensure that the garlic seed falls accurately into the planting hole.

[0038] Please see the appendix Figure 5 - Appendix Figure 6A buffer chamber 610 is slidably disposed above the feed inlet 9. An elastic telescopic rod 611 is fixed between the outer side of the buffer chamber 610 and the discharge chamber 601. The elastic telescopic rod 611 includes an outer cylinder and an inner rod that are slidably connected. An elastic element is sleeved in the area of ​​the inner rod inside the outer cylinder to keep the inner rod retracted inside the outer cylinder. Several grooves 612 are opened on the inner wall of the buffer chamber 610. A buffer plate 613 is rotatably connected to the inside of the grooves 612 through a torsion spring shaft. A buffer pad is fixed on the upper surface of the buffer plate 613. A rotating disk 614 is fixed through the drive end of the motor 604 through the discharge chamber 601. A protrusion 615 is fixed on the top of the rotating disk 614. An inclined block 616 is fixed on the outer wall of the buffer chamber 610 at the rotation trajectory of the protrusion 615. A rectangular or circular storage space is provided inside the buffer chamber 610.

[0039] Specifically, the bottom of the buffer chamber 610 slides down and inserts into the bottom of the feed inlet 9 under the pulling force of the elastic telescopic rod 611. At this time, the bottom of the seed guide tube 42 of the adjusting unit 4 is higher than the buffer plate 613. The buffer plate 613 rotates upward under the torque of the torsion spring shaft and abuts against the inner wall of the groove 612, thus maintaining a downward tilting posture. This makes the multiple sets of buffer plates 613 distributed in a cone shape. When the garlic seeds fall, they may be damaged when they hit the bottom due to their height. The buffer pad can cushion the falling garlic seeds and effectively offset the impact force of the garlic seeds falling from the seed guide tube 42, avoiding damage to the garlic seeds due to the height difference and protecting the integrity of the garlic seeds to the greatest extent. When the motor 604 drives the garlic feeding hopper 605 to rotate to the discharge port 8, it simultaneously drives the protrusion. 615 rotates to one side of the buffer chamber 610, and the protrusion 615 rotates along the inclined surface of the inclined block 616 to lift the buffer chamber 610 upward. At this time, by blocking the seed guide tube 42 of the adjustment unit 4, an outward pushing force can be applied to the buffer plate 613 when the buffer chamber 610 rises, so that the buffer plate 613 is stored in the groove 612, so that the garlic seed can fall smoothly into the seed hopper after buffering. The buffer chamber 610 achieves synchronous lifting and lowering through the cooperation of the elastic telescopic rod 611, the protrusion 615, and the inclined block 616. When the garlic hopper 605 is in place, the buffer plate 613 is accurately stored, which not only ensures that the garlic seed can be smoothly put into the hopper after buffering, avoiding jamming or leakage, but also simplifies the transmission structure without the need for additional power drive.

[0040] Please see the appendix Figure 8 The garlic-picking unit 3 includes several garlic-picking trays 31 connected by hollow pipes. A motor 32 is fixedly installed on the outer wall of the frame 1. The drive end of the motor 32 is fixedly connected to one end of the hollow pipe, and this end of the hollow pipe is sealed and closed. The other end of the hollow pipe passes through the frame 1 and is connected to the negative pressure device. The surface of the garlic-picking tray 31 is provided with multiple planes, and adsorption holes 33 are opened at the planes. The negative pressure device includes a negative pressure fan. The negative pressure fan and the hollow pipe are connected in sequence through a negative pressure pipe and a rotary joint.

[0041] Specifically, the negative pressure device creates negative pressure inside the garlic-picking disc 31 and generates adsorption force at the adsorption holes 33. The motor 32 drives the garlic-picking disc 31 to rotate. As the garlic-picking disc 31 rotates from bottom to top through the planting box 2, it adsorbs and fixes individual garlic seeds through the adsorption holes 33. During subsequent rotations, the garlic seeds are rotated to the detection and screening unit 5 for detection and screening. Qualified garlic seeds fall into the adjustment unit 4.

[0042] Please see the appendix Figure 8 - Appendix Figure 11 The detection and screening unit 5 includes a rotating frame 51 and a motor 52. The rotating frame 51 is rotatably installed inside the adjustment unit 4, and the motor 52 is fixedly installed on the outside of the adjustment unit 4, specifically in the adjustment chamber 41 of the adjustment unit 4. The drive end of the motor 52 is fixedly connected to the rotating frame 51. A motor 6 53 is fixedly installed at the center of the rotating frame 51. A detection platform 54 is fixedly installed at the drive end of the motor 6 53. An electromagnet 2 55 is embedded and fixedly installed inside the detection platform 54, and a flexible pad is fixedly installed at the top of the detection platform 54. The flexible pad is used to buffer the impact force of garlic seeds falling on the detection platform 54 and prevent the garlic seeds from jumping again. An adjustable angle detection device 56 is installed on the side wall of the detection platform 54. Several sealing plates 34 made of ferromagnetic material are set at the corresponding plane inside the garlic taking plate 31. An elastic telescopic rod 2 35 is fixedly installed between the sealing plate 34 and the garlic taking plate 31.

[0043] Specifically, the garlic-collecting tray 31, carrying the garlic seeds, rotates to directly above the detection and screening unit 5. At this time, the motor 6 53 drives the detection platform 54 to rotate one revolution, causing the detection device 56 to tilt from bottom to top and detect the bottom and sides of the garlic seeds. After the detection is completed, the electromagnet 2 55 is activated, generating a magnetic attraction force on the sealing plate 34, causing the sealing plate 34 to move downwards until it touches and blocks the adsorption hole 33. At this time, the garlic seeds fall onto the flexible pad, exposing their tops. Then, the detection device 56 rotates in the opposite direction and moves from top to bottom to detect the top of the garlic seeds. This not only achieves full-surface detection of the garlic seeds without dead angles, but also ensures accurate identification of various unqualified garlic seeds such as those that are too small, too large, double-clove, broken, moldy, or shriveled, effectively avoiding the impact of planting bad seeds on the germination rate and yield. After the detection is completed, the motor 52 rotates, driving the rotating frame 51 to rotate 90°, keeping the detection platform 54 vertical, so that the detected garlic seeds fall off.

[0044] The testing equipment 56 includes a fixed frame, one end of which is fixedly connected to the testing platform 54. An installation frame is rotatably connected inside the fixed frame, and an industrial camera is fixedly mounted on the installation frame. An angle adjustment motor is fixedly mounted on the outer wall of the fixed frame, and one end of the angle adjustment motor is fixedly connected to the shaft of the installation frame. The angle of the industrial camera is adjusted by the operation of the angle adjustment motor. The industrial camera is an industrial-grade global shutter color industrial camera, supplemented by a ring LED fill light and an IP65 dustproof and waterproof cover. Through the coordinated operation of the motor 53 and the electromagnet 55, it first scans the bottom and sides of the garlic seed from bottom to top as the testing platform 54 rotates. Then, after the garlic seed falls steadily onto the flexible pad, it rotates in the opposite direction to detect the upper surface. It can accurately identify whether the garlic seed size is compliant and whether there are defects such as breakage / moldy / shriveling. It can also preliminarily determine the orientation of the garlic tip. It solves the problems of single function and incomplete detection of traditional equipment and is suitable for complex environments such as field dust and light changes.

[0045] Please see the appendix Figure 8 - Appendix Figure 11 The adjustment unit 4 includes an adjustment chamber 41 fixedly connected to the frame 1. The bottom of the adjustment chamber 41 is open and a seed guide tube 42 is fixedly connected thereto. The seed guide tube 42 is prior art and will not be described in detail here. A single-end open rotating cylinder 43 is rotatably connected inside the adjustment chamber 41. Several annularly distributed separation plates 44 are fixedly provided on the outer wall of the rotating cylinder 43. A motor 49 is fixedly provided on the outer wall of the adjustment chamber 41. The drive end of the motor 49 is fixedly connected to the rotating cylinder 43. The upper inner wall of the adjustment chamber 41 is fixedly provided with figure-eight shaped guide layers. The guide layers are used to guide the falling direction of the garlic seeds and make them fall into the correct position. The rotating cylinder 43 has an opening 45 at the top, and the surface of the rotating cylinder 43 and the separating plate 44 are alternately provided with openings 45. The inner end of the rotating cylinder 43 is rotatably provided with a sorting cylinder 46 that passes through the adjustment chamber 41. One side of the sorting cylinder 46 has an opening 47, and the inner wall of the other side of the sorting cylinder 46 is fixed with an inclined layer. The outer wall of the adjustment chamber 41 is provided with a rotating device 48 that drives the sorting cylinder 46 to rotate. The rotating device 48 includes a shell fixed to the outside of the adjustment chamber 41. A drive motor is fixed to the outer wall of the shell. The drive shaft of the drive motor and one end of the sorting cylinder 46 are respectively fixedly connected with gears, and the two gears are meshed.

[0046] Specifically, initially, the rotating device 48 drives the sorting cylinder 46 to rotate, so that opening two 47 is at the bottom, thereby blocking opening one 45, which is also at the bottom. After inspection, qualified garlic seeds fall to the top opening one 45 and are located between the separating plates 44 on both sides. Then, the motor four 49 rotates, driving the rotating cylinder 43 to rotate, so that the next set of opening one 45 rotates to the top to receive the garlic seeds that fall next. When opening one 45 rotates to the seed guide tube 42, the garlic seeds are fed through the seed guide tube 42 to correct their posture so that the garlic tips are facing upwards. The separating plates 44 separate the garlic seeds, so that only one set of garlic seeds falls through the seed guide tube 42 at a time, ensuring the agronomic requirement of "one seed per hole". Before unqualified garlic seeds fall, the rotating device 48 drives the sorting cylinder 46 to rotate, so that opening two 47 rotates to the top. Unqualified garlic seeds then slide down through opening one 45 and opening two 47 and down the inclined layer to be discharged below the frame 1 for collection and waiting for further processing.

[0047] Workflow: S1. Preparation stage: The height of the frame 1 is adjusted by the electric push cylinder. Before sowing, the adjustment chamber 41 is made to fit the ground, and the shovel plate 603 moves with the device to level the soil. S2, Garlic Removal Stage: Motor 32 drives garlic removal plate 31 to rotate, and negative pressure device adsorbs garlic seeds in planting box 2 through adsorption hole 33. Individual garlic seeds are transferred with garlic removal plate 31. S3. Testing and screening process: Garlic seeds are transferred to testing and screening unit 5. Motors 52 and 6 drive the testing table 54 and testing equipment 56 to test the size and quality of garlic seeds on the entire surface, screen out unqualified garlic seeds, and retain qualified garlic seeds. S4. Orientation adjustment stage: Qualified garlic seeds fall into the adjustment chamber 41. Motor 49 drives the rotating drum 43 and the separating plate 44 to rotate. The sorting drum 46 works together to remove unqualified garlic seeds. Qualified garlic seeds are corrected in posture by the seed guide tube 42 to ensure that the garlic tip is facing upward. S5, Hole opening stage: Electromagnet 74 is de-energized, cylinder 72 drives hole opener 73 to move down, motor 731 drives drill bit 732 to rotate to break soil and open hole. During hole opening, slider 71 slides along the groove to make hole opening component 7 work in place. After completion, cylinder 72 is reset, and electromagnet 74 attracts slider 71 to reset. S6. Planting stage: After the garlic seed is adjusted in posture, it is buffered by the buffer chamber 610 and falls into the garlic feeding hopper 605. The second motor 604 drives the garlic feeding hopper 605 to rotate to the feeding port 8. The magnetic ring 609 attracts the first magnetic block 608, causing the lower pressure plate 607 to press the garlic seed. The garlic seed falls accurately into the planting hole through the feeding port 8, completing the planting.
