Description

Technical Field

[0001] This utility model belongs to the technical field of garlic planters, and in particular relates to a garlic seed dispensing structure for a garlic planter. Background Technology

[0002] In the garlic planting process, seed orientation is a key technical step that determines the planting quality. Existing garlic planters, due to factors such as soil conditions (soil moisture, particle size, soil type: clay or sand) and field conditions (area and shape), cannot guarantee that the garlic bulbils will face upwards and stand upright, thus affecting the planting effect and the final yield and quality.

[0003] Chinese patent application No. 202210870600.8 discloses a garlic planter, including a frame with a garlic planting device mounted on it. The garlic planting device includes one or more garlic planting mechanisms and a garlic seed metering box. The garlic planting mechanism includes a planting mechanism frame, a garlic seed metering device, and a furrow opener mounted on the planting mechanism frame. The garlic seed metering port is located above the furrow opener, which has a transition belt conveyor mechanism, including a garlic seed conveyor belt, an upper pulley, and a lower pulley. The garlic seed conveyor belt includes a conveyor belt and garlic receiving bodies spaced apart on the conveyor belt. The garlic seed metering device includes a garlic conveying chain support structure, a garlic conveying chain, and a protective cover to prevent garlic seeds from falling. The garlic conveying chain includes a chain and a composite seed scoop. The garlic receiving body is a leather support plate perpendicular to the belt surface, and the leather belt and the leather support plate are integrally formed.

[0004] In the above technical solution, when the garlic planter is planting, a garlic seed falling from the seed outlet is caught by the garlic receiving body. However, in the above technical solution, the garlic receiving body is a leather plate structure located below the seed outlet. This causes the garlic seed to fall onto the leather plate and, due to its elasticity, to be positioned at different angles in the groove between the leather plate and the belt surface. When the leather plate rotates to the other side under the drive of the belt, the garlic seed falls and the planting is completed. During this process, the garlic seed can fall horizontally, with the root facing down, or with the head facing down, making the falling direction of the garlic seed uncontrollable. It is impossible to ensure that the garlic scales are facing upwards and upright, thus affecting the planting effect and the final yield and quality. Summary of the Invention

[0005] To address the shortcomings of existing technologies, a garlic seed dispensing structure for a garlic planter is provided.

[0006] This utility model is achieved using the following technical solution:

[0007] A garlic seed dispensing structure for a garlic planter includes a body with a hopper having an inlet and an outlet. The body also includes a directional dispensing structure at the outlet of the hopper and a planting structure below the directional dispensing structure. The directional dispensing structure comprises opening and closing plates located on either side of the outlet of the hopper and capable of moving closer or further apart. The planting structure includes a rotating base capable of vertically rotating relative to the body and at least one dispensing unit rotatably connected to the side of the rotating base away from its axis. When the dispensing unit rotates to a position directly below the lower end of the opening and closing plates, the plates open, allowing the garlic seeds inside to fall into the dispensing unit, which then inserts the seeds into the soil.

[0008] When the garlic cloves with their buds facing upwards fall from the discharge port, they are caught and bound by two funnel-shaped opening and closing plates. When the dispensing unit rotates to a position directly below the lower end of the two opening and closing plates, the garlic cloves located in the funnel space are released. The dispensing unit rotates from the upper side near the bottom end of the opening and closing plates towards the soil and inserts the garlic cloves into the soil, completing the upright planting of the garlic cloves.

[0009] This invention uses a funnel-shaped space formed between two opening and closing plates to constrain the garlic seed in three dimensions. The natural falling process of the garlic seed is then planted through the mechanical transmission behavior of the opening and closing plates and the vertical rotation of the planting unit. This transforms the final state of the garlic seed placement from a probabilistic event into a deterministic physical process, ensuring that the initial state of "scalyx facing upwards" is transmitted undamaged to the final planting state, thereby guaranteeing the planting effect and the final yield and quality of the garlic seed.

[0010] Preferably, the hopper is also equipped with a chain-type feeding mechanism, which includes at least two sprockets, a chain and a seed spoon wrapped around the sprockets. The chain is wound around one of the inclined surfaces of the hopper inside the hopper, and the forward section of the chain used to drive the garlic seed upward is located on the side away from the inclined surface of the hopper. The seed spoon has a groove that matches the shape of the garlic seed. The opening direction of the groove is the same as the upward direction of the seed spoon driven by the forward section of the chain. A discharge channel is formed between the back end of the chain and the inner wall inclined surface of the hopper, and the end of the discharge channel is directly opposite the discharge port.

[0011] The garlic seeds in the hopper are first taken out one by one by the seed spoon through the chain feeding mechanism, and then slide down the inner wall slope of the hopper to the discharge port of the hopper. Since the groove in the seed spoon and the inner wall slope of the hopper form a V-shaped groove structure, the garlic seeds are in a flat state under their own gravity and fall out one by one from the discharge port.

[0012] Preferably, the inner wall of the hopper corresponding to the back section of the chain is an arc-shaped wall.

[0013] By setting the inner wall of the hopper to an arc shape, the garlic cloves are ensured to be positioned in the middle of the seed spoon, preventing them from falling out of the outlet at an inaccurate position.

[0014] Preferably, the two opening and closing plates include a fixed plate fixedly installed at the discharge port of the machine body and a rotating plate that can rotate relative to the fixed plate. The rotating plate and the fixed plate are closed to form a funnel-shaped structure. The rotating plate is provided with an extension portion extending towards the rotating seat. The width direction of the extension portion is perpendicular to the rotation direction of the rotating seat.

[0015] By rotating the rotating plate relative to the fixed plate, garlic seeds located in the funnel space are dispensed. When the garlic seeds fall, they are still limited by the fixed plate to prevent them from falling at an angle, thereby changing their position within the dispensing unit.

[0016] Preferably, the rotating shaft of the rotating plate is disposed on the machine body and located above the axial direction of the rotating plate. The rotating shaft is connected to the rotating plate through connecting arms symmetrically disposed on both sides of the rotating plate along the axial direction. The connecting arms are provided with connecting seats perpendicular to the opening and closing direction of the rotating plate. An elastic element is provided between the connecting seat and the fixed plate or the machine body.

[0017] By placing the rotating shaft above the rotating plate, the opening angle between the rotating plate and the fixed plate is reduced while ensuring that the garlic seeds can fall freely. By setting an elastic element so that the rotating plate can automatically reset after opening, the garlic seeds can be placed one by one, which helps to ensure the initial position of the garlic seeds.

[0018] The elastic element can be any existing elastic unit that can open the rotating plate and then return it to a closed state through its own elastic force, such as a tension spring connected between the connecting seat and the body or an elastic sleeve wrapped between the connecting seat and the body.

[0019] Preferably, the rotating seat is equipped with a planetary transmission assembly, and the delivery unit is powered by the power output end of the planetary transmission assembly and always remains in a vertical state under the action of the planetary transmission assembly, thereby making the delivery unit always revolve in a vertical state, which facilitates the receiving and planting of garlic seeds.

[0020] Preferably, the delivery unit includes a crossbeam fixedly connected to the output end of the planetary transmission assembly, opening and closing rotating shafts respectively set at the head and root of the crossbeam, and an arc-shaped plate sleeved on the opening and closing rotating shafts and hanging downwards. The two opening and closing rotating shafts are parallel to the rotating seat, and the two arc-shaped plates form a funnel-shaped structure when closed.

[0021] By designing the dispensing unit into a funnel-shaped structure similar to the shape of an opening and closing plate, the falling posture of the garlic seeds can be screened, and they can be isolated from the free fall channel. This ensures that the garlic seeds are always kept upright, thereby guaranteeing the planting effect and the final yield and quality of the garlic seeds.

[0022] Preferably, an actuating rod is provided on the opening and closing shaft located near the rotating seat to abut against the extension on the rotating plate. The actuating rod is perpendicular to the axial direction of the opening and closing shaft and located at the center line of the arc plate.

[0023] During the revolution of the curved plate, the actuating rod abuts against the extension of the rotating plate, thereby causing the rotating plate to rotate relative to the fixed plate. The opening between the two plates is achieved by simple mechanical transmission, without the need for a separate power source to achieve the opening between the two plates.

[0024] Preferably, the rotating seat has a protrusion near the crossbeam, and a swing arm is provided on the opening and closing shaft located near the side of the rotating seat. The swing arm extends upward along the radial direction of the crossbeam, and the other end of the swing arm is provided with a rotating wheel for abutting against the protrusion. There are meshing parts between the two opening and closing shafts, and the ends of the two meshing parts that contact each other are engaged in a gear-like manner.

[0025] Under the action of the planetary transmission assembly, when the rotating seat drives the arc plate to rotate, the arc plate always remains in a vertical state, which causes the rotating wheel to rotate relative to the protrusion until it abuts against the protrusion. When the rotating wheel abuts against the protrusion, the protrusion causes the swing arm to swing through the rotating wheel. The swing arm drives the lower arc plate to rotate around the opening and closing pivot, and makes it the driving component for transmission. The arc plate drives the other arc plate to rotate through the meshing part in a gear transmission manner, thereby realizing the synchronous opening and closing of the two arc plates.

[0026] Preferably, a synchronous transmission component is provided between the rotating seat and one of the sprockets, thereby enabling the rotating seat to be linked with the chain-type feeding mechanism.

[0027] The synchronous transmission component can be any existing transmission structure that can drive the central shaft of the rotating seat and the sprocket to rotate synchronously, such as two pulleys coaxially arranged with the sprocket of the rotating seat and a belt wound between the two pulleys.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] By constructing a rigid three-dimensional constraint system in the funnel space formed between the rotating plate and the fixed plate, the garlic seed is precisely locked in place during the initial placement stage. Then, by controlling the rotation trajectory and opening and closing of the arc plate, the free fall of the garlic seed during the conventional placement and planting process is replaced. The entire process of garlic seed from feeding to planting is transformed into a closed state transmission channel, completely eliminating random disturbances in each stage of traditional planting. It has the advantage of being able to transfer the initial state of garlic seed with the scales facing upwards to the final state of planting without damage, thereby ensuring the planting effect and the final yield and quality of garlic seed.

[0042] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0043] like Figure 1 As shown, this embodiment discloses a garlic seed dispensing structure for a garlic planter, including a body with a hopper 1 on it. The hopper 1 has an inverted trapezoidal structure, with an upward-opening inlet on the upper side and at least one downward-opening outlet on the lower side. The body is equipped with a chain-type feeding mechanism 10 wound around one of the inclined surfaces of the hopper 1, a directional dispensing structure 20 located at the outlet of the hopper 1, and a planting structure 30 located below the directional dispensing structure 20. Figure 3 As shown, the chain-type feeding mechanism 10 includes a first sprocket 11, a second sprocket 12, and a chain 13 that winds around the first sprocket 11 and the second sprocket 12, as shown. Figure 9 , Figure 10 As shown, seed scoops 14 are arranged in an array along the rotation direction of the chain 13. The seed scoops 14 have grooves 141 that fit the shape of garlic seeds. The chain 13 rotating from the first sprocket 11 to the second sprocket 12 is the forward segment, and the chain 13 rotating from the second sprocket 12 to the first sprocket 11 is the reverse segment. The forward segment of the chain 13 is located on the side away from the inclined surface of the hopper 1 and drives the garlic seeds to rise through the seed scoops 14. The opening direction of the grooves 141 on the seed scoops 14 is the same as the rising direction of the forward segment of the chain 13. A material discharge channel 15 is formed between the reverse end of the chain 13 and the inclined surface of the inner wall of the hopper 1. The end of the material discharge channel 15 is directly opposite the discharge port. The inner wall of the hopper 1 corresponding to the reverse segment of the chain 13 is an arc-shaped wall 16.

[0044] As the chain 13 drives the seed spoon 14 to rotate, the seed spoon 14 drives the garlic seeds in the hopper 1 to move synchronously through the groove 141. The forward section of the chain 13 drives the garlic seeds to rise through the seed spoon 14. After the seed spoon 14 moves to the backward section of the chain 13, the garlic seeds are separated from the groove 141 due to gravity and are blocked by the back of the seed spoon 14 located below the current seed spoon 14. At this time, the back of the seed spoon 14 on the lower side supports the garlic seeds and keeps the garlic seeds in a flat position.

[0045] The directional dispensing structure 20 includes a fixed plate 22 fixedly installed at the discharge port of the machine body and a rotating plate 21 that can rotate relative to the fixed plate 22. Each discharge port corresponds to a set of fixed plates 22 and rotating plates 21. When the rotating plate 21 and the fixed plate 22 are closed, they form a funnel-shaped structure. Figure 2 As shown, the rotating plate 21 has symmetrically arranged extensions 211 on both sides of the funnel-shaped structure along its axis. The width direction of the extensions 211 is perpendicular to the rotation direction of the rotating seat 31. The rotation axis of the rotating plate 21 is mounted on the machine body and located above the axial direction of the rotating plate 21. The rotation axis is connected to the rotating plate 21 through connecting arms 23 symmetrically arranged on both sides of the rotating plate 21 along its axis. The connecting arms 23 are provided with a first connecting seat 24 perpendicular to the opening and closing direction of the rotating plate 21. A second connecting seat 25 is provided on the machine body near the first connecting seat 24. The second connecting seat 25 is located on the back side of the fixed plate 22, as shown in the figure. Figure 2 As shown, an elastic element, namely a tension spring 26, is provided between the first connecting seat 24 and the second connecting seat 25.

[0046] The planting structure 30 includes a rotating base 31 capable of rotating vertically relative to the machine body, a planetary transmission assembly 32 disposed within the rotating base 31, and two dispensing units, such as... Figure 7 As shown, the power output end of the planetary transmission assembly 32 extends outward from the side of the rotating seat 31 away from the axis. The delivery unit is fixedly mounted on the power output end of the planetary transmission assembly 32. When the rotating seat 31 rotates, the internal planetary transmission assembly 32 causes the delivery unit to revolve synchronously with the rotating seat 31 while rotating relative to the rotating seat 31, thus maintaining a vertical state under the action of the planetary transmission assembly 32.

[0047] When the dispensing unit rotates to a position directly below the lower end of the rotating plate 21 and the fixed plate 22, the dispensing unit is used to receive the garlic seeds; when the dispensing unit rotates to a position directly below the lower end of the rotating plate 21 and the fixed plate 22, the dispensing unit first inserts itself downward into the soil, and then opens to dispense the garlic seeds into the soil.

[0048] like Figure 4 As shown, a belt drive assembly 27 is provided between the rotating seat 31 and the first sprocket 11. The belt drive assembly 27 includes two pulleys that are coaxially arranged with the rotating seat 31 and the first sprocket 11 respectively, and a drive belt wound between the two pulleys.

[0049] like Figure 5 As shown, the delivery unit includes a crossbeam 34 fixedly connected to the output end of the planetary transmission assembly 32, opening and closing rotating shafts 35 respectively set at the head and root of the crossbeam 34, and an arc-shaped plate 36 sleeved on the opening and closing rotating shafts 35 and hanging downward. The two arc-shaped plates 36 form a funnel-shaped structure when closed. The crossbeam 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. The opening and closing rotating shaft 35 located near the rotating seat 31 is provided with a lever 39 for abutting against the extension 211 on the rotating plate 21. The lever 39 is perpendicular to the axial direction of the opening and closing rotating shaft 35 and located at the center line of the arc-shaped plate 36.

[0050] As the actuating rod 39 revolves with the rotating seat 31, it moves upward along the circumference and abuts against the extension 211 of the rotating plate 21, thereby opening the rotating plate 21. This causes the garlic seed between the rotating plate 21 and the fixed plate 22 to fall between the two arc-shaped plates 36. The endpoint of the free fall of the garlic seed is the axial position of the arc-shaped plate 36 where it matches the diameter of the garlic seed.

[0051] like Figure 6 As shown, a protrusion 33 is provided on the rotating seat 31 near the crossbeam 34, such as... Figure 8 As shown, a swing arm 37 is provided on the opening and closing shaft 35 located near the rotating seat 31. The swing arm 37 extends upward along the radial direction of the crossbeam 34. The other end of the swing arm 37 is provided with a rotating wheel 38 for abutting against the protrusion 33. There are meshing parts 40 arranged opposite to each other between the two opening and closing shafts 35. The ends of the two meshing parts 40 that are in contact are meshed in a gear-like manner.

[0052] When the rotating wheel 38 abuts against the protrusion 33, the protrusion 33 causes the swing arm 37 to swing through the rotating wheel 38. The swing arm 37 drives the lower arc plate 36 to rotate around the opening and closing shaft 35, and makes it the driving member for transmission. The arc plate 36 drives another arc plate 36 to rotate through the meshing part 40 in a gear transmission manner, thereby realizing the synchronous opening and closing of the two arc plates 36.

[0053] Example 2

[0054] The difference between this embodiment and Embodiment 1 is that: Figure 11 As shown, a protrusion 33 is provided on the rotating seat 31 near the crossbeam 34. The protrusion 33 includes an annular protrusion 42 integrally formed with the rotating seat 31 and a wedge-shaped protrusion 43 provided on the annular protrusion 42. The wedge-shaped protrusion 43 is used to push the swing arm 37 and drive the lower arc plate 36 to rotate with the opening and closing pivot 35 as the axis. The wedge-shaped protrusion 43 forms an arc-shaped semi-enclosed structure surrounding the outside of the crossbeam 34.
