Description

Technical Field

[0001] The present invention belongs to the technical field of garlic seeding, and particularly relates to a garlic grain transportation, positive bud, and seeding monomer of a garlic seeding machine. Background Art

[0002] During the garlic seeding process, seed orientation is a key technical link determining seeding quality. In the existing garlic seeding machines during use, due to factors such as soil conditions (soil humidity, particle size, whether the soil texture is clay or sandy soil) and field conditions (area and shape), it is difficult to achieve precise positive bud orientation, and problems of inaccurate orientation are likely to occur, thus unable to ensure that the garlic scales are upward and upright, affecting the seeding effect and the final yield and quality.

[0003] Chinese Patent Application No. 202510189430.0 discloses a plastic luminous badminton, including a feeding component, an identification component, and a seeding component; the feeding component includes a conveying groove and an adjusting clamping groove connected to each other, and the adjusting clamping groove is installed on a frame plate; the identification component includes a positioning sensor on one side of the adjusting clamping groove and an image acquisition element on the other side of the adjusting clamping groove; the seeding component includes a seeding duckbill that rotates around the working axis and remains vertical, the seeding duckbill is located below the frame plate and the adjusting clamping groove, the seeding duckbill is provided with a cavity with an open top, the positioning sensor is used to identify the relative position of the seeding duckbill and the adjusting clamping groove, an intermediate clamping groove for receiving the garlic seeds output from the adjusting clamping groove is installed in the cavity, so that the cavity is divided into an adjusting cavity and an execution cavity, a partition brush extending into the adjusting cavity is provided on the seeding duckbill, and according to the attitude of the garlic seeds obtained by the image acquisition element, the partition brush disturbs the garlic seeds falling into the execution cavity through the intermediate clamping groove to make the garlic seed scales upward.

[0004] In the above technical solution, with the partition brush as the disturbance unit, by symmetrically arranging the partition brushes in each seeding duckbill, the garlic seeds falling into the execution cavity are made to have their scales upward. However, in the above technical solution, the garlic seeds in a lying state perform free fall in the cavity, and the partition brush opposite to the position of the garlic seed scales uses the free fall of the garlic seeds to stir the garlic seeds. Due to the uncontrollability of external forces during the use of the garlic seeding machine, the force of the partition brush stirring the garlic seeds easily causes the garlic seeds to rotate over-position. For example, the garlic seeds rotate from the left lying position to the vertical state under the stirring of the partition brush and then continue to rotate to the right lying position, thus unable to ensure that the garlic seeds finally falling freely into the soil have their scales upward; and due to the volume limitation of the partition brush itself, after being stirred by the partition brush, the garlic seeds cannot rotate within the preset rotation plane and may also rotate to the front lying position or the back lying position, unable to solve the randomness of the scale orientation during the garlic seed seeding process, thus affecting the seeding effect and the final yield and quality, and the use effect is not good. Summary of the Invention

[0005] To address the deficiencies in the prior art, a garlic seed transportation, correct-bud, and sowing unit for a garlic planter is provided.

[0006] The present invention is implemented by the following technical solutions:

[0007] A garlic seed transportation, correct-bud, and sowing unit for a garlic planter includes a machine body. A hopper is provided on the machine body. The hopper is provided with a feed inlet and a discharge outlet. A direction-adjusting structure is provided on the machine body at the discharge outlet of the hopper, and a planting structure is provided below the direction-adjusting structure. The direction-adjusting mechanism includes a direction-adjusting platform located below the discharge outlet for receiving garlic seeds and a driving mechanism for driving the direction-adjusting platform to swing. The direction-adjusting platform is provided with a direction-adjusting shovel surface that can make the garlic seeds lie flat only in the forward or backward direction. The area between the direction-adjusting shovel surface and the discharge outlet is the direction-adjusting space. A visual detection device facing the direction-adjusting space is provided inside the machine body. When the visual detection device detects the orientation information of the garlic bud of the garlic seeds, the direction-adjusting mechanism can make the garlic bud of the garlic seeds fall into the planting structure at an upward angle through the direction-adjusting platform, and the planting structure inserts the garlic seeds into the soil.

[0008] The garlic seeds fall from the discharge outlet into the direction-adjusting platform. When the visual detection device detects the orientation information of the garlic bud of the garlic seeds, the driving mechanism is controlled to start. After the driving mechanism swings the garlic seeds through the direction-adjusting platform, the roots of the garlic seeds first slide out of the direction-adjusting shovel surface, and then fall in the direction with the garlic bud facing upward, ensuring the direction of sowing the garlic seeds.

[0009] Among them, the driving mechanism can drive the direction-adjusting platform to swing horizontally through transmission (i.e., the swinging direction corresponds to the tip and root directions of the garlic seeds). When the direction-adjusting platform drives the garlic seeds to collide with the inner wall of the machine body, the inner wall squeezes the garlic seeds out of the direction-adjusting platform and they fall under the action of gravity. The corresponding transmission method is that the driving mechanism is vertically connected to the direction-adjusting platform.

[0010] Among them, the driving mechanism can drive the direction-adjusting platform to swing vertically through transmission (i.e., the swinging trajectory of the direction-adjusting platform swings around the driving mechanism with the distance from the driving mechanism as the radius). The garlic seeds fall under the action of gravity during the swinging process of the direction-adjusting platform. The corresponding transmission method is that the driving mechanism is connected to the upper side position of the direction-adjusting platform.

[0011] Among them, the visual detection device is any existing detection unit that can drive the direction-adjusting mechanism to start in different directions through the control center after collecting the orientation information of the garlic bud of the garlic seeds, such as a camera.

[0012] The present invention can drive the orientation platform to move through a driving mechanism, and enable the garlic seeds to fall freely under the action of gravity, realizing the automatic orientation of the garlic seed bulb buds. Furthermore, during the planting process of the garlic seeds, the seeds are planted with the bulb buds facing upward, ensuring the verticality rate of the garlic seeds after being planted in the soil. The final state of placing the garlic seeds is transformed from a probabilistic event into a deterministic physical process, enabling the initial state of "the bulb buds facing upward" to be transmitted to the planting final state without loss, which is beneficial to the later growth and development of garlic, thus ensuring the sowing effect of the garlic seeds and the final yield and quality, and realizing the vertical planting of garlic.

[0013] Preferably, the orientation platform includes a first shovel surface and a second shovel surface arranged oppositely, and a horizontal plane located between the first shovel surface and the second shovel surface. The first shovel surface, the horizontal plane, and the second shovel surface together form an orientation shovel surface that penetrates along the width direction of the orientation platform. The inclination angle of the first shovel surface is the same as the sliding angle of the garlic seeds along the inner wall of the hopper, and the driving mechanism is located at the middle position above the first shovel surface.

[0014] By arranging the first shovel surface and the second shovel surface on the orientation platform, after the garlic seeds fall into the orientation shovel surface, they can be buffered and stopped under the action of the second shovel surface. Compared with the way of directly letting the garlic seeds fall on the horizontal plane, it can avoid the garlic seeds from being damaged or rolling out of the orientation shovel surface directly due to inertia, thus preventing the orientation of the garlic seed bulb buds from getting out of control during planting and affecting the verticality rate of the garlic seeds after being planted in the soil.

[0015] Preferably, a chain type feeding mechanism is further arranged in the hopper, which can convey the garlic seeds to the orientation shovel surface one by one in a lying state.

[0016] By arranging the chain type feeding mechanism, the garlic seeds in the hopper are taken out one by one first and slide down along the inner wall inclined surface of the hopper to the discharge port of the hopper. Since the chain type feeding mechanism and the inner wall inclined surface of the hopper form a V-shaped groove structure, the garlic seeds are in a lying state under the action of their own gravity and fall into the orientation shovel surface until they do so. This facilitates feeding the garlic seeds in the hopper one by one and makes the garlic seeds in the orientation shovel surface in a lying state, which is convenient for the orientation platform to control the orientation of the garlic seeds.

[0017] Preferably, the driving mechanism includes a driving motor arranged on the machine body and a swing arm connected to the power output end of the driving motor. The swing arm makes the whole orientation platform located on the lower side of the power output end of the driving motor.

[0018] By arranging a swing arm between the driving rotating shaft and the orientation platform, there is a certain distance between the axis of the orientation platform and the axis of the power output end of the driving motor. Thus, the orientation platform can swing with the length between the axis of the power output end of the driving motor as the radius.

[0019] Preferably, the swing arm includes a vertical swing arm connected to the power output end of the driving motor and a horizontal swing arm connected to the end of the vertical swing arm. A limit slideway is provided at the position of the body opposite to the end of the horizontal swing arm. The horizontal swing arm passes through the limit slideway and is connected to the back of the first shovel surface of the steering platform.

[0020] The driving motor's power output end drives the vertical swing arm to swing, and the movement trajectory of the horizontal swing arm is restricted by the limit chute, so that the limit chute plays a role in supporting and limiting the horizontal swing arm, thereby preventing the swing arm and the steering platform from deforming after long-term use, which may cause the steering platform to be difficult to receive the falling garlic seeds and affect the upright rate of the garlic seeds during planting.

[0021] Preferably, the midline or parallel of the garlic seed dropping end after the steering platform swings to the extreme position coincides with the discharge port of the hopper.

[0022] When the garlic seeds fall along the shovel surface of the steering platform, under the action of gravity and the shovel surface of the steering platform, there will be no deflection angle between the dropping trajectory of the garlic seeds and the midline of the discharge port of the hopper, thus further ensuring the dropping trajectory of the garlic seeds under their own gravity and preventing the garlic seeds from flipping after falling along the shovel surface of the steering platform, which affects the upright rate of the garlic seeds.

[0023] Preferably, on both sides of the discharge port of the hopper, there are also opening and closing plates located below the steering platform and capable of approaching or separating relatively. The internal space after the two opening and closing plates are closed is in a flaring shape from bottom to top, and the width between the lower ends of the two opening and closing plates is less than or equal to the average value of the roots of the garlic seeds.

[0024] Among them, the relative approaching or separating action between the two opening and closing plates can be realized by existing power sources respectively supplying power to the two opening and closing plates; it can also be realized by the contact during the rotation of the planting structure, so that one of the opening and closing plates moves relatively away from the other opening and closing plate, and then closes under its own gravity.

[0025] Among them, when the relative approaching or separating action between the two opening and closing plates is realized by one of the opening and closing plates moving relatively away from the other opening and closing plate, the re-closure between the two opening and closing plates can be realized by any existing connection structure that can make it return to its initial state, such as a spring arranged between the two opening and closing plates, or two opening and closing plates with different magnetic poles, or a torsion spring arranged on the rotation shaft of the opening and closing plate.

[0026] The internal space after the two opening and closing plates are closed can be funnel-shaped or semi-hourglass-shaped; the garlic seeds are three-dimensionally rigidly constrained by the inverted conical space formed between the two opening and closing plates, and the final state of the natural falling process of the garlic seeds is transformed from a probabilistic event into a deterministic physical process, so that the initial state of "the bud facing up" is transmitted to the planting final state without loss.

[0027] Preferably, the planting structure includes a rotating base capable of vertically rotating relative to the machine body and at least one delivery unit rotatably connected to the side of the rotating base away from the axis, the rotating base is equipped with a gear transmission assembly capable of enabling the delivery unit to always maintain a vertical state during its revolution, and the opening and closing plate opens when the delivery unit moves vertically to a position directly below the lower end of the opening and closing plate.

[0028] By means of the gear transmission assembly, the delivery unit is always allowed to revolve in a vertical state, thereby facilitating the reception and planting of garlic seeds.

[0029] Preferably, the delivery unit comprises a beam fixedly connected to the output end of the gear transmission assembly, an opening and closing shaft respectively arranged at the head and root of the beam, and an arc-shaped plate sleeved on the opening and closing shaft and hanging downward, the two opening and closing shafts are parallel to the rotating seat, the internal space of the two arc-shaped plates after closing is expanded from bottom to top, and the width between the lower ends of the two arc-shaped plates is less than or equal to the average value of the roots of the garlic seeds.

[0030] The arc-shaped plate may be an arc-shaped duckbill plate structure or a semi-conical shell structure or a combination of a semi-conical shell structure and a semi-cylindrical shell structure located at the lower end of the semi-conical shell structure.

[0031] The internal space of the delivery unit is designed as an inverted cone-shaped space, and the width of the inverted cone-shaped space gradually decreases from top to bottom to perform three-dimensional rigid constraints on the garlic seeds, so that the garlic seeds can be stopped at any height position that matches the radial circumference of the garlic seeds in an upright state, so that the garlic seeds can always remain in an upright state, thereby ensuring the sowing effect of the garlic seeds and the final yield quality.

[0032] Preferably, a protrusion is provided on the rotating seat near the cross beam, and a swing arm is provided on the opening and closing rotating shaft located on one side near the rotating seat, the swing arm extends upward along the radial direction of the cross beam, and a rotating wheel for abutting against the protrusion is provided at the other end of the swing arm, and an engaging portion is relatively arranged between the two opening and closing rotating shafts, and the contacting ends of the two engaging portions are meshed in a gear-like manner, and a toggle rod for abutting against the extension portion on the rotating plate is provided on the opening and closing rotating shaft located on one side near the rotating seat, and an extension portion extending toward the direction close to the rotating seat is provided on the opening and closing plate opposite to the revolution direction of the delivery unit, and the width direction of the extension portion is perpendicular to the rotation direction of the rotating seat.

[0033] The arc-shaped plates can be reset and closed by arranging a torsion spring around the circumference of the opening and closing shaft or by the deadweight of the two arc-shaped plates.

[0034] When the rotating wheel abuts against the protrusion, the protrusion swings the swing arm through the rotating wheel, and the swing arm drives the lower arc plate to rotate with the opening and closing rotating shaft as the axis, and makes it act as an active part for transmission. The arc plate drives the other arc plate to rotate through the bite part in a gear transmission manner, thereby realizing the synchronous opening and closing of the two arc plates; in the process of driving the arc plate to revolve, the toggle rod abuts against the extension part of the opening and closing plate opposite to the revolving direction of the delivery unit, so that the opening and closing plate opposite to the revolving direction of the delivery unit rotates relative to the opening and closing plate set oppositely, and the opening between the two opening and closing plates is realized by simple mechanical transmission, so there is no need to set up a separate power source for realizing the opening between the two opening and closing plates.

[0035] Compared with the prior art, the beneficial effects of the present invention are:

[0036] The garlic seed planting process is automated. The garlic seeds are loaded one by one through a chain-type feeding mechanism and then fall into the adjustment bucket. Under the action of the adjustment platform, the garlic seeds fall along the shovel surface of the adjustment platform, and fall between the two opening and closing plates and into the placing unit in a manner in which the roots of the garlic seeds are downward and the bulbs are upward. The garlic seeds are buried in the soil by the placing unit for planting, so that the final state of the garlic seed placement is transformed from a probabilistic event into a deterministic physical process, and the initial state of "bulbs facing upward" is transmitted losslessly to the final state of planting, which has the advantages of ensuring the upright rate of the garlic seeds after entering the soil, being beneficial to the growth and development of the garlic in the later stage, thereby achieving the advantage of upright planting of the garlic.

[0054] The present invention will be further described below based on the accompanying drawings and specific embodiments.

[0055] Embodiment 1

[0056] As shown Figure 1 in the figure, this embodiment discloses a garlic grain transportation, positive bud, and sowing unit of a garlic planter, including a machine body 1. A hopper 10 is provided on the machine body 1. The hopper 10 has an inverted trapezoidal structure throughout. An upward-opening feed inlet is provided on the upper side of the hopper 10, and at least one downward-opening discharge outlet is provided on the lower side of the hopper 10. A chain-type feeding mechanism wound around the hopper 10 along one of the inclined surfaces of the hopper 10, an orientation adjustment structure located at the discharge outlet of the hopper 10, and a planting structure located below the orientation adjustment structure are provided on the machine body 1. The chain-type feeding mechanism includes a first sprocket 11, a second sprocket 12, and a chain 13 wound between the first sprocket 11 and the second sprocket 12. Seed scoops 14 are arranged in an array along the rotation direction of the chain 13 on the chain 13. A groove 141 that fits the shape of the garlic seeds is provided on the seed scoop 14. As shown Figure 13 and Figure 14 in the figure, a tongue plate-shaped side wall extending outward is provided on the groove 141. As shown Figure 3 in the figure, the chain 13 rotating from the first sprocket 11 to the second sprocket 12 is the forward section, and the chain 13 rotating from the second sprocket 12 to the first sprocket 11 is the reverse section. The forward section of the chain 13 is located on the side away from the inclined surface of the hopper 10. When the forward section of the chain 13 drives the seed scoop 14 to rise, the tongue plate-shaped side wall is located at the lower end of the seed scoop 14, and the seed scoop 14 drives the garlic seeds to rise through the tongue plate-shaped side wall. The opening direction of the groove 141 on the seed scoop 14 is the same as the rising direction of the forward section of the chain 13. As shown Figure 4 in the figure, a blanking channel 15 is formed between the reverse section of the chain 13 and the inner wall inclined surface of the hopper 10. The end of the blanking channel 15 is directly opposite to the discharge outlet. As shown Figure 2 in the figure, the inner wall of the hopper 10 corresponding to the reverse section of the chain 13 is an arc wall 101.

[0057] During the process of the chain 13 driving the seed scoop 14 to rotate, the seed scoop 14 drives the garlic seeds located in the hopper 10 to move synchronously through the groove 141. The forward section of the chain 13 drives the garlic seeds to rise through the seed scoop 14. After the seed scoop 14 moves to the reverse section of the chain 13, the garlic seeds are separated from the groove 141 due to gravity and are blocked by the back surface of the seed scoop 14 located below the current seed scoop 14. At this time, the back surface of the lower seed scoop 14 supports the garlic seeds and makes the garlic seeds all lie flat. When the seed scoop 14 drives the garlic seeds to move to the discharge outlet of the hopper 10, the garlic seeds slide along the direction of the arc wall 101 onto the orientation adjustment mechanism.

[0058] The direction - adjusting mechanism is located at the discharge port on the lower side of the hopper 10. The direction - adjusting mechanism includes a direction - adjusting platform 22 located below the discharge port for receiving garlic seeds, a driving rotating shaft 20, a swing arm 21 connected between the direction - adjusting platform 22 and the driving rotating shaft 20, and a driving motor 19 for driving the driving rotating shaft 20 to rotate. An installation seat 18 is provided on the outer end face of the machine body 1. The driving motor 19 is fixedly arranged in the installation seat 18. The driving rotating shaft 20 is connected to the power output end of the driving motor 19. The installation seat 18 is of a hollow - shell structure and semi - wraps the outside of the driving motor 19. The opening of the installation seat 18 is located on the side away from the power output end of the driving motor 19. The driving rotating shaft 20 is perpendicular to the width direction of the direction - adjusting platform 22 and is located at the middle position above the direction - adjusting platform 22. When the driving rotating shaft 20 rotates, the driving rotating shaft 20 can drive the direction - adjusting platform 22 to swing along its own width direction through the swing arm 21.

[0059] As Figure 8 shown, the upper end face of the direction - adjusting platform 22 includes a first shoveling surface 221 and a second shoveling surface 223 arranged oppositely, and a horizontal plane 222 arranged between the first shoveling surface 221 and the second shoveling surface 223. The first shoveling surface 221, the second shoveling surface 223, and the horizontal plane 222 jointly form a direction - adjusting shoveling surface 23 that penetrates the direction - adjusting platform 22 along its own width direction, so that the direction - adjusting platform 22 has a relatively horizontal V - shaped shoveling structure. The inclination angle of the first shoveling surface 221 is the same as the sliding angle of the garlic seeds along the inner wall of the hopper 10. When the direction - adjusting platform 22 swings to the extreme position, the edge of the garlic seeds sliding relatively on the direction - adjusting platform 22 is parallel to the mid - line of the discharge port of the hopper 10. Further, when the garlic seeds fall along the shoveling surface of the direction - adjusting platform 22, under the action of gravity and the shoveling surface of the direction - adjusting platform 22, no deflection angle is formed between the falling trajectory of the garlic seeds and the mid - line of the discharge port of the hopper 10, thereby further ensuring the falling trajectory of the garlic seeds under their own gravity and preventing the garlic seeds from flipping after falling along the shoveling surface of the direction - adjusting platform 22, which affects the standing - upright rate of the garlic seeds.

[0060] The included angle between the second shoveling surface 223 and the horizontal direction is smaller than the included angle between the first shoveling surface 221 and the horizontal direction. Since the direction - adjusting shoveling surface 23 is V - shaped, after the garlic seeds fall, under the influence of their own gravity, they are in a lying - flat state along the width direction of the direction - adjusting platform 22 within the direction - adjusting shoveling surface 23. The area between the direction - adjusting shoveling surface 23 and the discharge port is the direction - adjusting space 16.

[0061] As Figure 8 shown, the swing arm 21 includes a vertical swing arm 211 connected to the power end of the driving rotating shaft 20 and a horizontal swing arm 212 connected to the end of the vertical swing arm 211. The included angle between the horizontal swing arm 212 and the vertical swing arm 211 is greater than ninety degrees. An L - shaped part 213 is connected between the horizontal swing arm 212 and the back position of the first shoveling surface 221. A protrusion 214 is provided between the vertical section of the L - shaped part 213 and the end of the horizontal swing arm 212. As Figure 6 、Figure 7 As shown in the figure, a limiting slideway 102 is opened at the end position of the transverse swing arm 212 of the machine body 1, and the transverse swing arm 212 passes through the limiting slideway 102 and is connected to the back position of the first shovel surface 221 of the steering platform 22.

[0062] As Figure 5 shown in the figure, a visual detection device 17 is provided in the machine body 1 opposite to the steering space 16. The visual detection device 17 is any existing detection unit that can drive the steering mechanism to start in different directions through the control center after collecting the orientation information of the garlic bud of the garlic seed, such as a visual camera; the drive motor 19 is any existing power motor that can rotate forward or backward under the control of the visual detection device 17.

[0063] The two opening and closing plates are respectively a first opening and closing plate 24 fixedly arranged at the discharge port of the machine body 1 and a second opening and closing plate 25 that can rotate relative to the first opening and closing plate 24. A set of first opening and closing plate 24 and second opening and closing plate 25 corresponds to the lower part of the steering space 16 of each discharge port. The internal space after the first opening and closing plate 24 and the second opening and closing plate 25 are closed is funnel-shaped, and the width between the lower ends of the two opening and closing plates is less than or equal to the average value of the roots of the garlic seeds.

[0064] As Figure 3 shown in the figure, on the second opening and closing plate 25, extension parts 251 are symmetrically arranged along the axis on both sides of the outer surface of the funnel shape. The width direction of the extension parts 251 is perpendicular to the opening and closing direction between the first opening and closing plate 24 and the second opening and closing plate 25. The rotation axis of the second opening and closing plate 25 is arranged on the machine body 1 and above the axial position of the farthest point from the first opening and closing plate 24 at the upper end of the second opening and closing plate 25. The rotation axis is connected to the second opening and closing plate 25 through opening and closing swing arms 26 symmetrically arranged along the axis on both sides of the second opening and closing plate 25. The opening and closing swing arms 26 can be linear oblique connecting arms or bent L-shaped connecting arms.

[0065] A first connecting seat 27 perpendicular to the opening and closing direction of the second opening and closing plate 25 is arranged on the opening and closing swing arm 26. A second connecting seat 28 is arranged on the machine body 1 near the first connecting seat 27. The second connecting seat 28 is located on the back side of the first opening and closing plate 24. An elastic member is arranged between the first connecting seat 27 and the second connecting seat 28, and the elastic member is a tension spring 29.

[0066] As Figure 9 、 Figure 10 shown in the figure, the planting structure includes a rotating seat 31 that can rotate vertically relative to the machine body 1, a gear transmission component 32 arranged in the rotating seat 31, and two feeding units 33, as Figure 11As shown, the power output end of the gear transmission assembly 32 extends outward from the side of the rotating seat 31 away from the axis. The feeding unit 33 is fixedly arranged on the power output end of the gear transmission assembly 32. When the rotating seat 31 rotates, the internal gear transmission assembly 32 causes the feeding unit 33 to revolve synchronously with the rotating seat 31 and rotate relative to the rotating seat 31, so as to always maintain a vertical state under the action of the gear transmission assembly 32.

[0067] When the feeding unit 33 rotates to a position directly below the lower ends of the second opening and closing plate 25 and the first opening and closing plate 24, the feeding unit 33 is used to receive garlic seeds; when the feeding unit 33 rotates to a position away from the position directly below the lower ends of the second opening and closing plate 25 and the first opening and closing plate 24, the feeding unit 33 first inserts downward into the soil, and then opens and drops the garlic seeds into the soil.

[0068] As Figure 3 shown, a belt transmission assembly 30 is provided between the rotating seat 31 and the first sprocket 11. The belt transmission assembly 30 includes two pulleys coaxially arranged with the rotating seat 31 and the first sprocket 11 respectively and a transmission belt wound between the two pulleys.

[0069] As Figure 12 shown, the feeding unit 33 includes a cross beam 34 fixedly connected to the output end of the gear transmission assembly 32, opening and closing rotating shafts 35 respectively arranged at the head and root of the cross beam 34, and arc-shaped plates 36 sleeved on the opening and closing rotating shafts 35 and hanging downward. The cross beam 34 is perpendicular to the axial end face of the rotating seat 31. The two opening and closing rotating shafts 35 are parallel to the rotating seat 31. A shifting rod 37 for abutting against the extension part 251 on the second opening and closing plate 25 is arranged on the opening and closing rotating shaft 35 close to the rotating seat 31. The shifting rod 37 is perpendicular to the axial direction of the opening and closing rotating shaft 35 and is located at the midline position of the arc-shaped plate 36.

[0070] Both of the two arc-shaped plates 36 are in the shape of duckbill plates with symmetrical settings. The internal space between the two arc-shaped plates 36 gradually decreases from top to bottom, which is convenient for continuing the garlic seeds in the direction with the bud facing upward and is convenient for piercing into the soil.

[0071] When the shifting rod 37 revolves with the rotating seat 31, the shifting rod 37 moves upward along the circumferential direction and abuts against the extension part 251 of the second opening and closing plate 25, thereby opening the second opening and closing plate 25, and then causing the garlic seeds between the second opening and closing plate 25 and the first opening and closing plate 24 to fall between the two arc-shaped plates 36. The free-fall end position of the garlic seeds is the axial position at the place on the arc-shaped plate 36 that fits the diameter of the garlic seeds.

[0072] A protrusion 38 is provided at a position on the rotating base 31 close to the cross beam 34. The protrusion 38 is integrally formed with the rotating base 31. The protrusion 38 includes a butting plane portion 382 protruding outward and butting ramps 381 provided on both sides of the butting plane portion 382. The butting plane portion 382 and the butting ramps 381 are combined to form an arc-shaped semi-enclosure structure surrounding the cross beam 34.

[0073] An opening and closing lever 40 is provided on the opening and closing rotating shaft 35 on the side close to the rotating base 31. A reset member for resetting and closing the two opening and closing plates is provided between the opening and closing lever 40 and the cross beam 34. The reset member is a torsion spring (not shown in the figure) wound around the circumferential position of the opening and closing rotating shaft 35. The opening and closing lever 40 extends upward in the radial direction of the cross beam 34. A rotating wheel 41 for butting against the protrusion 38 is provided at the other end of the opening and closing lever 40. A meshing portion 39 is provided oppositely between the two opening and closing rotating shafts 35. One ends of the two meshing portions 39 in contact are meshed in a gear shape.

[0074] During the process of the rotating base 31 driving the arc-shaped plate 36 to revolve through the cross beam 34, under the action of the gear transmission assembly 32, the cross beam 34 rotates relative to the end face of the rotating base 31. During this process, the cross beam 34 drives the rotating wheel 41 to roll along the protruding end face of the protrusion 38 through the opening and closing lever 40. The rotating wheel 41 gradually climbs onto the butting plane portion 382 along the butting ramp 381. Since the rotating wheel 41 abuts against the butting ramp 381, the butting ramp 381 causes the opening and closing lever 40 to swing through the rotating wheel 41. The opening and closing lever 40 drives the arc-shaped plate 36 below to rotate with the opening and closing rotating shaft 35 as the axis, and twists the torsion spring, and makes it act as a driving member for transmission. The arc-shaped plate 36 drives the other meshing portion 39 to rotate in a gear transmission manner through the meshing portion 39, so as to synchronously rotate the other arc-shaped plate 36, realizing the synchronous opening of the two arc-shaped plates 36. When the rotating wheel 41 rolls along the butting plane portion 382, the two arc-shaped plates 36 remain in a continuously open state, and the duration of the rotating wheel 41 rolling along the butting plane portion 382 is the duration of the two arc-shaped plates 36 in the open state. When the rotating wheel 41 continues to roll along the butting ramp 381, the torsion spring closes the arc-shaped plate 36 gradually through its own elastic force.

[0075] When it is necessary to plant garlic seeds, the garlic seeds are placed in the hopper 10, and the chain feeding mechanism is started. The first sprocket 11 drives the seed spoon 14 to move upward through the forward section of the chain 13, and the seed spoon 14 takes out the garlic seeds one by one through the groove 141. When the chain 13 drives the seed spoon 14 to move to the reverse section, the garlic seeds fall between the back side of the tongue-shaped side wall of the lower seed spoon 14 and the arc wall 101, and move down along the arc wall 101 of the hopper 10 with the lower seed spoon 14. Under the guidance of the arc wall 101, the garlic seeds lie flat due to their own gravity until they fall out of the drop channel 15. When the flat-lying garlic seeds fall into the shovel surface 23, the visual detection device 17 collects the orientation information of the garlic bulbs and passes through The control center starts the driving motor 19, and the driving motor 19 drives the adjustment platform 22 to swing along the root of the garlic seed toward the bulb of the garlic seed through the swing arm 21, so that when the adjustment platform 22 drives the garlic seed to swing upward, the root of the garlic seed first slides to the adjustment platform 22 under the action of its own gravity. At this time, the garlic seed falls between the first opening and closing plate 24 and the second opening and closing plate 25 in an upright state with the bulb facing upward, and is clamped and constrained by the inner walls of the first opening and closing plate 24 and the second opening and closing plate 25. At the same time, the rotating seat 31 is started synchronously with the chain 13 under the action of the belt transmission assembly 30, and the rotating seat 31 drives the delivery unit 33 to rotate upward to a position close to the first opening and closing plate 24 and the second opening and closing plate 25. The toggle rod 37 moves upward along the circumferential direction during the revolution of the rotating seat 31, and the toggle rod 37 abuts against the extension portion 251 of the second opening and closing plate 25, thereby opening the second opening and closing plate 25, and the garlic seeds between the first opening and closing plate 24 and the second opening and closing plate 25 fall into the two arc-shaped plates 36 of the delivery unit 33, and continue to be clamped and constrained by the inner walls of the two arc-shaped plates 36, so that the garlic seeds still maintain an upright state with the bulbs facing upward. When the rotating seat 31 drives the delivery unit 33 to rotate past the lower ends of the two opening and closing plates, it continues to rotate downward along the circumferential direction, and the delivery unit 33 is inserted into the soil. At this time, the crossbeam 34 drives the rotating wheel 41 to rotate relative to the rotating seat 31 and abuts against the slope The path 381 gradually climbs onto the abutment plane portion 382, and the abutment plane portion 382 pushes the opening and closing lever 40 to swing in the direction away from the rotating seat 31, and the opening and closing lever 40 drives the arc plate 36 located at the lower end of the inner opening and closing shaft 35 to swing in the direction close to the rotating seat 31, and the arc plate 36 located at the lower end of the inner opening and closing shaft 35 drives the arc plate 36 located at the lower end of the outer opening and closing shaft 35 to swing in the direction away from the rotating seat 31 through the bite portion 39, thereby opening the two arc plates 36, and then burying the garlic seeds in the soil, and rotating upward again under the revolution of the rotating seat 31, and receiving the garlic seeds dropped from the first opening and closing plate 24 and the second opening and closing plate 25 again, completing the upright planting of the garlic seeds one by one.

[0076] Embodiment 2

[0077] The difference between this embodiment and the first embodiment is that: Figure 15As shown in the figure, both of the two arc-shaped plates 36 are semi-funnel-shaped structures 361 that are symmetrically arranged. After the two arc-shaped plates 36 are closed, the internal space gradually narrows from top to bottom. At the lower ends of the two arc-shaped plates 36, there are also semi-cylindrical structures 362 that are convenient for piercing into the soil, thereby facilitating the continuation of the garlic seeds in the direction with the bud facing upwards and facilitating piercing into the soil.

[0078] Embodiment III

[0079] In this embodiment, the differences from Embodiment I and Embodiment II are as follows: As Figure 16 shown in the figure, a convex structure 42 is provided at a position on the rotating seat 31 close to the cross beam 34. The convex structure 42 is in a circular ring shape. At a position on the rotating seat 31 close to the convex structure 42, there is a gasket structure 43 that can push the opening and closing lever 40. The gasket structure 43 includes a contact plane portion 382 provided on the axial circular ring surface of the convex structure and contact ramps 381 provided on both sides of the contact plane portion 382. The contact plane portion 382 and the contact ramps 381 are combined to form an arc-shaped semi-enclosure structure surrounding the cross beam 34.
