Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, and in particular relates to a positive bud structure for a garlic planter. Background Technology

[0002] In garlic planting, seed orientation is a crucial technical step that determines planting quality. Currently, various garlic seed orientation devices are available on the market, mainly including water-floating seed method, spiral spring method, seed bud tip method, and multi-layer cone cup method. These mechanical orientation methods are mostly designed based on the physical characteristics of garlic, such as its center of gravity being close to the tail or the seed buds being slender. However, these orientation methods, which rely on the physical properties of garlic, have certain limitations. In practical applications, they often struggle to achieve precise bud orientation, easily leading to inaccurate orientation, thus affecting planting results and final yield and quality.

[0003] Chinese patent application No. 201910548762.8 discloses a machine vision-based automatic garlic orientation control planter, including a frame, a three-point suspension, a seed box, a seed picking mechanism, a turntable-type orientation planting mechanism, an image acquisition device, a controller, a press wheel, walking wheels, a gearbox, and a controller. The image acquisition device is fixedly connected to the frame via an image acquisition device bracket and is located directly above the turntable-type orientation planting mechanism, used to acquire the posture image of the garlic seed in the inoculation groove. The controller is installed at the rear of the frame. The image acquisition device is connected to the controller, and the controller is connected to the tilting motor. The controller processes the image to obtain the orientation of the garlic seed scales and sends a command to control the tilting motor to drive the inoculation groove to rotate clockwise or counterclockwise.

[0004] In the above technical solution, the duckbill opening and closing mechanism is combined with the duckbill planting mechanism. The orientation of the garlic seed scales is adjusted by flipping the inoculation groove. However, in the above technical solution, after the image acquisition device collects the information of the garlic seed scales, it controls the directional motor to drive the inoculation groove to rotate in a flipping manner. In the implementation process, the rotation amplitude is too large. After being flipped, the garlic seed scales continue to rotate a certain angle due to inertia as they fall into the lower duckbill opening and closing mechanism. As a result, the actual orientation of the garlic seed scales does not match the actual orientation of the garlic seed scales required by controlling the flipping of the inoculation groove. There is a possibility that the inoculation groove will cause the garlic seed scales to rotate out of position, resulting in poor performance and affecting the planting effect and the final yield and quality. Summary of the Invention

[0005] To address the shortcomings of existing technologies, a positive bud structure for garlic planters is provided.

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

[0007] A garlic planter with a bud-aligning structure includes a body with a hopper having an inlet and an outlet. The body also includes a directional mechanism located at the outlet of the hopper. This directional mechanism comprises a directional shovel below the outlet for receiving garlic seed buds and a drive mechanism above the directional shovel. The area between the directional shovel and the outlet is a directional space. The body contains a visual detection device that directs the garlic seed buds towards this space. When the visual detection device detects the orientation of the garlic seed buds, the directional mechanism uses the directional shovel to cause the buds to fall at an upward angle.

[0008] Garlic seeds fall from the discharge port into the directional groove of the directional bucket. When the vision detection device detects the orientation of the garlic seed scales, it controls the drive mechanism to start. The drive shaft drives the directional bucket through transmission to make the garlic seed swing. The root of the garlic seed first slides out of the directional groove, and then falls with the scales facing upward, ensuring the orientation of the garlic seed.

[0009] The drive mechanism can drive the directional bucket to swing horizontally (i.e., the swing direction corresponds to the tip and root of the garlic clove). When the directional bucket causes the garlic clove to collide with the inner wall of the machine, the inner wall squeezes the garlic clove out of the directional bucket and it falls off under the action of gravity. The corresponding transmission method is that the drive mechanism is vertically connected to the directional bucket.

[0010] The drive mechanism can drive the directional bucket to swing vertically through transmission (i.e., the swing trajectory of the directional bucket swings with the drive mechanism's rotating shaft as the center and the distance between the rotating shaft and the rotating shaft as the radius). The garlic cloves fall off under the action of gravity during the swing of the directional bucket. The corresponding transmission method is that the drive mechanism is connected to the upper side of the directional bucket.

[0011] Among them, the visual inspection device is any existing inspection unit that can be activated in different directions by the control center after collecting the orientation information of the garlic seed scales, such as a camera.

[0012] This invention uses a drive mechanism to move the directional bucket in a swinging manner, causing the garlic cloves to fall freely under gravity. This achieves automatic orientation of the garlic clove scales, ensuring that the garlic cloves are planted with the scales facing upwards during planting. This guarantees the upright planting rate of the garlic cloves after they are planted in the soil, which is beneficial to the later growth and development of the garlic, thus achieving upright planting of garlic.

[0013] Preferably, the directional bucket includes a first shovel surface, a second shovel surface, and a horizontal surface located between the first shovel surface and the second shovel surface. The first shovel surface, the horizontal surface, and the second shovel surface together form a directional groove that runs through the width of the directional bucket. The inclination angle of the first shovel surface is the same as the angle at which the garlic seeds slide down the inner wall of the hopper. The angle between the second shovel surface and the horizontal direction is smaller than the angle between the first shovel surface and the horizontal direction. The driving mechanism is located at the middle position above the first shovel surface.

[0014] By setting a first shovel surface and a second shovel surface on the directional bucket, the garlic cloves can be buffered and stopped by the action of the second shovel surface after falling into the directional groove. Compared with the method of letting the garlic cloves fall directly onto the horizontal surface, this can prevent the garlic cloves from being injured or rolling directly out of the directional groove due to inertia, thus preventing the garlic cloves from losing their orientation when planted and affecting the uprightness rate of the garlic cloves after being planted in the soil.

[0015] Preferably, the hopper is also equipped with a chain-type feeding mechanism that can convey garlic cloves one by one into the directional groove in a flat state.

[0016] By setting up a chain-type feeding mechanism, the garlic seeds in the hopper are taken out one by one and slide down the inclined inner wall of the hopper to the discharge port of the hopper. Since the chain-type feeding mechanism and the inclined inner wall of the hopper form a V-shaped groove structure, the garlic seeds are made to lie flat under their own gravity until they fall into the adjusting groove. This makes it easy to feed the garlic seeds in the hopper one by one and make the garlic seeds in the adjusting groove lie flat.

[0017] Preferably, the drive mechanism includes a drive motor mounted on the machine body and a drive shaft powered by the drive motor. The power output shaft of the drive motor is powered by the drive shaft. A connecting arm is fixedly provided between the power output end of the drive shaft and the directional bucket. The connecting arm allows the directional bucket to be positioned entirely below the drive shaft.

[0018] By setting a connecting arm between the drive shaft and the directional bucket, a certain distance is maintained between the axis of the directional bucket and the axis of the drive shaft, thereby enabling the directional bucket to swing with the length between itself and the axis of the drive shaft as the radius.

[0019] Preferably, the connecting arm includes a vertical swing arm connected to the power end of the drive shaft and a horizontal swing arm connected to the end of the vertical swing arm, and an L-shaped component is connected between the horizontal swing arm and the back side of the first shovel surface.

[0020] By setting the connecting arm to have a shape with a vertical swing arm and a horizontal swing arm, and connecting the connecting arm and the directional bucket through an L-shaped component, it is easy to adjust the distance between the directional bucket and the discharge port, thereby facilitating the constraint of the directional space.

[0021] Preferably, the angle between the lateral swing arm and the vertical swing arm is greater than 90 degrees, so that the lateral swing arm is subjected to the gravity of the bucket and generates a component force along the length of the lateral swing arm, thereby increasing the structural strength between the vertical swing arm and the lateral swing arm and preventing the lateral swing arm from deforming under gravity.

[0022] Preferably, the drive motor and the connecting arm are both located outside the machine body. The machine body has a limiting groove at the end position of the transverse swing arm. The vertical section of the L-shaped part is connected to the end of the transverse swing arm, and the horizontal section of the L-shaped part passes through the limiting groove and extends into the adjustment space.

[0023] By driving the rotating shaft to swing the connecting arm, and restricting the movement trajectory of the L-shaped part through the limiting slide groove, the connecting arm and the directional bucket are prevented from deforming after long-term use, which would make it difficult for the directional bucket to catch the falling garlic cloves, thus affecting the uprightness of the garlic cloves during planting.

[0024] Preferably, the outer end face of the machine body is provided with a mounting base for mounting the drive motor. The mounting base is a hollow structure and is partially wrapped around the outside of the drive motor. The vertical swing arm is always in close contact with the outer surface of the mounting base during the swinging process. The vertical swing arm is provided with an outwardly protruding step. The outer surface of the mounting base is provided with a groove that matches the step. The curvature of the groove and the step matches the swing trajectory of the vertical swing arm.

[0025] By setting a groove on the side of the mounting base that fits against the vertical swing arm, the vertical swing arm is supported in the vertical direction, preventing the weight of the vertical swing arm and the structure connected to the end of the vertical swing arm from bending the drive shaft, thereby affecting the service life of the drive shaft.

[0026] Preferably, a protrusion is provided between the vertical section of the L-shaped component and the end of the transverse swing arm, thereby reinforcing the connection between the vertical section of the L-shaped component and the end of the transverse swing arm and further ensuring the structural strength of the connection.

[0027] Preferably, after the directional bucket swings to its extreme position, the end of the garlic clove falling coincides with or is parallel to the centerline of the hopper's discharge port. Thus, when the garlic clove falls along the shovel surface of the directional bucket, under the action of gravity and the action of the shovel surface, the falling trajectory of the garlic clove will not form an angle with the centerline of the hopper's discharge port. This further ensures the falling trajectory of the garlic clove under its own gravity, preventing the garlic clove from turning over after falling along the shovel surface of the directional bucket, which would affect the uprightness of the garlic clove.

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

[0029] The garlic seed planting process is automated by using a chain-type feeding mechanism to feed the garlic seeds one by one and then drop them into the directional bucket. The garlic seeds fall freely due to the swing of the directional bucket, with the roots facing down and the buds facing up. This ensures that the garlic seeds are planted upright after being planted, which is beneficial to the later growth and development of garlic, thus achieving the advantage of upright garlic planting.

[0039] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0040] like Figure 1 As shown, this embodiment discloses a positive bud structure for a garlic planter, including a body 11. The body 11 has an upward-opening hopper 12. The upper opening of the hopper 12 is a feed inlet, and the lower opening is a discharge outlet. A chain-type feeding mechanism is installed inside the hopper 12. Figure 2 As shown, a chain-type feeding mechanism is wound around one of the inclined surfaces of the hopper 12. The chain-type feeding mechanism includes a chain 13 and a support seat 14. The support seat 14 has a semi-duckbill-shaped groove 15 that matches the shape of the garlic cloves. The opening direction of the semi-duckbill-shaped groove 15 is the same as the upward direction of the support seat 14 driven by the forward end of the chain 13. The inner wall of the hopper 12 opposite to the back end of the chain 13 is an outwardly protruding arc-shaped wall. A material drop channel 16 is formed between the back end of the chain 13 and the inclined surface of the inner wall of the hopper 12, which facilitates feeding the garlic cloves in the hopper 12 one by one.

[0041] As the chain 13 drives the bearing seat 14 to rotate, the bearing seat 14 drives the garlic seed located in the hopper 12 to move synchronously through the semi-duckbill groove 15. The forward end of the chain 13 drives the garlic seed to rise through the bearing seat 14. After the bearing seat 14 moves to the opposite end of the chain 13, the garlic seed separates from the semi-duckbill groove 15 due to gravity and is blocked by the bearing seat 14 located below the current bearing seat 14. At this time, the back of the lower bearing seat 14 supports the garlic seed, thereby preventing the garlic seed from falling out of the hopper 12 at too fast a speed.

[0042] like Figure 3 As shown, the machine body 11 is provided with a directional mechanism located at the discharge port on the lower side of the hopper 12. The directional mechanism includes a directional shovel 18 located below the discharge port for receiving garlic seeds, a drive shaft 21, and a connecting arm 20 connecting the directional shovel 18 and the drive shaft 21. The drive shaft 21 is perpendicular to the width direction of the directional shovel 18 and is located in the middle position above the directional shovel 18. When the drive shaft 21 rotates, the drive shaft 21 can drive the directional shovel 18 to swing along its own width direction through the connecting arm 20.

[0043] like Figure 8As shown, the upper surface of the directional bucket 18 includes a first shovel surface 181 and a second shovel surface 183 arranged opposite each other. The inclination angle of the first shovel surface 181 is the same as the angle at which the garlic seeds slide down the inner wall of the hopper 12. After the directional bucket 18 swings to its limit position, the second shovel surface 183 is parallel to the centerline of the discharge port of the hopper 12. Therefore, when the garlic seeds fall along the shovel surface of the directional bucket 18, under the action of gravity and the action of the shovel surface of the directional bucket 18, the falling trajectory of the garlic seeds will not form an angle with the centerline of the discharge port of the hopper 12. This further ensures the falling trajectory of the garlic seeds under their own gravity and prevents the garlic seeds from falling along the shovel surface of the directional bucket 18. After the garlic cloves fall and flip, they become dislodged, affecting their uprightness. The angle between the second shovel surface 183 and the horizontal direction is smaller than the angle between the first shovel surface 181 and the horizontal direction. A horizontal surface 182 is also provided between the first shovel surface 181 and the second shovel surface 183. The first shovel surface 181, the second shovel surface 183, and the horizontal surface 182 together form an adjusting groove 19 that runs through the adjusting bucket 18 along its width. Because the adjusting groove 19 is V-shaped, the garlic cloves, after falling, lie flat in the adjusting groove 19 under the influence of their own gravity, along the width direction of the adjusting bucket 18. The area between the adjusting groove 19 and the discharge port is the adjusting space 17. Figure 3 As shown, the body 11 is equipped with a visual detection device 25 facing the adjustment space 17. The visual detection device 25 is any existing detection unit that can be activated in different directions by the control center after collecting the orientation information of the garlic seed scales.

[0044] like Figure 4 , Figure 5 As shown, the outer end face of the body 11 is provided with a mounting base 22. A drive motor 23 for driving the drive shaft 21 to rotate is fixed inside the mounting base 22. The drive shaft 21 is connected to the power output end of the drive motor 23. The mounting base 22 is a hollow shell structure and is partially wrapped around the outside of the drive motor 23. The drive motor 23 is any existing power motor that can rotate in the forward or reverse direction under the control of the vision detection device 25.

[0045] When the vision detection device 25 detects the orientation information of the garlic seed scales, it starts and controls the drive motor 23 to swing the directional bucket 18 in the corresponding swing direction. The directional bucket 18 drives the garlic seed to swing synchronously and then falls down.

[0046] like Figure 8 As shown, the connecting arm 20 includes a vertical swing arm 201 connected to the power end of the drive shaft 21 and a horizontal swing arm 202 connected to the end of the vertical swing arm 201. The angle between the horizontal swing arm 202 and the vertical swing arm 201 is greater than 90 degrees. An L-shaped member 203 is connected between the horizontal swing arm 202 and the back position of the first shovel surface 181. A protrusion 204 is provided between the vertical section of the L-shaped member 203 and the end of the horizontal swing arm 202.

[0047] like Figure 6 , Figure 7 As shown, the drive motor 23 and the connecting arm 20 are both located outside the body 11. The body 11 has a limiting groove 24 at the end of the horizontal swing arm 202. The vertical section of the L-shaped part 203 is connected to the end of the horizontal swing arm 202. The horizontal section of the L-shaped part 203 passes through the limiting groove 24 and extends into the adjustment space 17. The vertical swing arm 201 has an outwardly protruding step 2011. The outer surface of the mounting base 22 has a groove (not shown in the figure) that matches the step 2011. The curvature of the groove and the step 2011 matches the swing trajectory of the vertical swing arm 201. The vertical swing arm 201 is always in close contact with the outer surface of the mounting base 22 during the swing. The vertical section of the L-shaped part 203 is always in close contact with the periphery of the body 11 corresponding to the limiting groove 24 during the swing.

[0048] When garlic seeds need to be planted, the chain-type feeding mechanism is activated. The chain 13 drives the garlic seeds upward through the support seat 14. After the support seat 14 removes the garlic seeds from the hopper 12 one by one, they enter the discharge channel 16. At this time, the garlic seeds disengage from the support seat 14 due to gravity and are blocked by the support seat 14 located below the current support seat 14. The back of the lower support seat 14 supports the garlic seeds, thus preventing them from falling into the discharge hopper 12 at too fast. When the garlic seeds move to the discharge port, they lose the support of the support seat 14 and fall into the adjusting groove 19 under their own weight. After the visual detection device 25 detects the orientation information of the garlic seed scales, it starts and controls the drive motor 23 to drive the drive shaft 21 to rotate in the corresponding swing direction. The drive shaft 21 drives the L-shaped part 203 to swing along the trajectory of the limiting slide groove 24 through the connecting arm 20, thereby driving the directional bucket 18 to swing from the position of the garlic seed root to the position of the scales. The directional bucket 18 drives the garlic seed to swing synchronously. After the directional bucket 18 swings through a certain angle, when the component of the garlic seed's gravity along the inner wall of the directional groove 19 is greater than the friction between the two, the garlic seed swings down and is then planted.
