Description

Technical Field

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

[0002] Currently, garlic cultivation relies heavily on manual transplanting. To ensure planting quality, during the garlic planting process, on the one hand, larger and plump garlic cloves are selected. Garlic cloves store sufficient nutrients, which allows the garlic seedlings to grow stronger after sprouting. On the other hand, according to the agronomic requirements for garlic planting in my country, garlic cloves should be planted in an upright position with the buds facing upwards, meaning the garlic roots must be inserted into the soil downwards. Garlic grown with cloves upside down will have a yield that will decrease by more than 30%. At the same time, soil should be covered after transplanting. However, in manual planting, it is necessary to frequently bend over to pick up the garlic cloves for transplanting, and at the same time, it is necessary to adjust the position of the garlic cloves, which is time-consuming and labor-intensive. In addition, it is difficult to ensure the consistency of planting, making it difficult to guarantee planting efficiency and planting quality. Summary of the Invention

[0003] To address the problems of high labor intensity, low efficiency, and inability to guarantee planting results in existing manual garlic planting methods, this invention provides a garlic planting device. The device adjusts the garlic's posture horizontally as it falls onto the conveying mechanism via a feeding mechanism. Then, a posture adjustment mechanism further adjusts the garlic's posture so that its roots fall downwards into the planting mechanism. Finally, a pressing mechanism presses the garlic roots downwards into the soil to complete the planting process, effectively improving planting efficiency and ensuring planting quality.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: A garlic planting device includes a trolley and a storage mechanism, a conveying mechanism, a posture adjustment mechanism, a planting mechanism, a pressing mechanism, a ditching mechanism, and a soil covering mechanism mounted on the trolley. The storage mechanism, located above the conveying mechanism, stores garlic seeds to be planted. A feeding mechanism is located at the lower end of the storage mechanism, used to adjust the feeding posture and interval of the garlic seeds. The posture adjustment mechanism is located between the conveying mechanism and the planting mechanism, used to ensure that the roots of the garlic seeds fall downwards into the planting mechanism. The planting mechanism is located at the end of the conveying mechanism, used to ensure and limit the falling posture of the garlic seeds. The pressing mechanism is located behind the planting mechanism, used to press the garlic seeds in the planting mechanism downwards so that their roots are inserted into the soil. A ditching mechanism is located at the front of the lower end of the planting mechanism, and a soil covering mechanism is located at the rear of the lower end. The ditching mechanism is used to dig trenches for planting the garlic seeds, and the soil covering mechanism is used to cover the planted garlic seeds. The above structure enables fully mechanized garlic planting.

[0005] Preferably, the storage mechanism is a funnel-shaped seed bin, and the feeding mechanism includes a feeding cylinder fixedly installed on the lower side of the seed bin and a feeding roller rotatably installed inside the feeding cylinder. The feeding cylinder has feeding holes on both the upper and lower sides. The feeding hole on the upper side corresponds to and communicates with the lower opening of the seed bin. There is a gap between the feeding roller and the inner wall of the feeding cylinder. The width of the feeding hole corresponds to the thickness of the garlic seed. The feeding roller has multiple first-type grooves equidistantly opened on the circumferential direction. The first-type grooves are elliptical grooves and their length direction is consistent with the axial direction of the feeding roller. The garlic seed enters the first-type groove through the upper feeding hole and restricts the length direction of the garlic seed to achieve the posture adjustment of the garlic seed. As the feeding roller rotates, the garlic seed in the first-type groove passes through the lower feeding hole and falls onto the conveying mechanism.

[0006] Preferably, the conveying mechanism is a belt conveyor, and the conveyor belt of the conveying mechanism has multiple second-type grooves, which correspond vertically to the first-type grooves. The second-type grooves are elliptical grooves and their length direction is consistent with the width direction of the conveyor belt. Garlic seeds falling in the first-type groove fall into the corresponding second-type groove, ensuring the posture of the garlic seeds during the conveying process.

[0007] Preferably, the second type of groove has symmetrical clamping grooves on both sides of the middle part, which makes it easy to insert into the second type of groove to clamp the garlic cloves.

[0008] Preferably, a vision mechanism is provided above the conveying mechanism to identify the orientation of the roots of the garlic cloves on the conveying mechanism.

[0009] Preferably, the posture adjustment mechanism includes a first slide rail, on which a first slider is slidably disposed along the garlic conveying direction. A first power mechanism is fixedly disposed on the first slider and a rack is slidably disposed up and down. The output end of the first power mechanism is connected to a first gear, which meshes with the rack. A second power mechanism is fixedly disposed at the lower end of the rack. The output end of the second power mechanism is connected to a swing block. A third power mechanism and a gripper are respectively disposed on both sides of the lower end of the swing block. The third power mechanism is used to drive the gripper to open and close, thereby gripping the garlic seed and driving the garlic seed to rotate until the root is facing down before moving it above the planting mechanism and placing it down.

[0010] Preferably, the sowing mechanism includes multiple receiving hoppers fixedly mounted on a trolley, and a cylindrical body fixedly mounted and connected to the lower side of the receiving hoppers. The receiving hoppers and the rear side of the cylindrical body are provided with connected strip-shaped holes. The lower rear end of the cylindrical body is provided with an inverted V-shaped hole, which is connected to the corresponding strip-shaped hole. Spring sheets are evenly distributed around the inner circumference of the cylindrical body. The upper and lower ends of the spring sheets are fixedly connected to the inner wall of the cylindrical body. A first spring is fixedly mounted between the inner side of the middle of each spring sheet and the inner wall of the cylindrical body. The garlic seed with the root falling downwards is clamped by the action of the first spring and the spring sheet.

[0011] Preferably, the pressing mechanism includes a fourth power mechanism fixedly mounted on the trolley. The output end of the fourth power mechanism is fixedly connected to a cam and an elliptical gear. Second slide rails are fixedly mounted on both sides of the trolley. Bearing seats are slidably mounted in the second slide rails. A baffle is fixedly mounted at the rear end of the second slide rails. A second spring is fixedly mounted between the bearing seats and the baffle. A rotating shaft is rotatably mounted between the two bearing seats. A second gear is fixedly connected to both ends of the rotating shaft after extending out of the corresponding bearing seats. The second gear meshes with the corresponding elliptical gear. Pressing rods are symmetrically fixedly mounted on the rotating shaft. The pressing rods correspond to the strip holes. A groove is formed at the free end of the pressing rod. The groove extends radially through the end of the pressing rod. The distance between the two opposite sidewalls of the groove is less than the thickness of the garlic seed. The rotating shaft drives the pressing rod to rotate and press the garlic seed downward. The rotation of the cam drives the pressing rod to rotate and move back and forth simultaneously, ensuring that the pressing rod presses the garlic seed in a manner close to downward pressing.

[0012] Preferably, the trenching mechanism includes a trench opener fixedly installed at the lower front end of each sowing mechanism, the trench opener corresponding to the front and back of the strip hole to ensure that the garlic seed falls into the trench dug by the trench opener.

[0013] Preferably, the soil covering mechanism includes an installation rod fixedly installed at the lower rear end of the trolley, and a soil covering component corresponding to the front and rear of the trenching mechanism is fixedly installed on the lower side of the installation rod. The soil covering component includes two soil covering plates, which are symmetrical about the corresponding trenching mechanism and arranged in a figure-eight shape. The distance between the two soil covering plates is greater than the thickness of the garlic seed and the gap at the rear end is smaller than the gap at the front end. The soil covering plates push soil from both sides to the middle to cover the lower part of the garlic seed inserted into the soil.

[0014] The beneficial effects of the present invention through the above technical solution are as follows: 1. This invention completes garlic sowing by moving a trolley and coordinating multiple mechanisms on the trolley, eliminating the need for manual intervention, effectively reducing labor intensity, improving sowing efficiency, and enabling one sowing per hole. Furthermore, this invention allows for sowing garlic seeds, greatly improving the problems of over-sowing and missed sowing in existing garlic sowing machinery, ensuring that the garlic seeds are planted upright in the soil with uniform plant spacing, meeting the agronomic requirements for single upright sowing of garlic, and guaranteeing the yield and quality of garlic.

[0015] The plants are evenly spaced, have good sowing posture, and 2. The present invention utilizes a first type of groove on the feeding roller, so that when the feeding roller rotates to correspond with the upper feeding hole, the garlic seeds in the seed bin fall into the corresponding first type of groove. Due to the shape limitation of the first type of groove, only one garlic seed can be placed at a time, and the length direction of the garlic seed is consistent with the axial direction of the feeding roller. As the feeding roller rotates to correspond with the lower feeding hole, the garlic seed falls onto the conveying mechanism. The spacing between the corresponding first type of grooves in the circumferential direction is the same, so the garlic seeds fall in sequence, realizing the adjustment of the garlic seed posture (i.e., the length direction of the garlic seeds falling on the conveying mechanism is consistent) and the consistency of the interval during the conveying process.

[0016] 3. The present invention uses a second type of groove on the conveyor belt of the conveying mechanism. As the feeding roller and the conveyor belt rotate, when a first type of groove rotates to correspond with the feeding hole below, a second type of groove is exactly corresponding with the first type of groove. This ensures that each garlic seed falling from the feeding mechanism falls into the corresponding second type of groove, thus guaranteeing the posture of the garlic seed during the conveying process (i.e., the length direction of the garlic seed is consistent with the width direction of the conveyor belt).

[0017] 4. The present invention uses a moving gripper to grip the garlic seed in the second type of groove by cooperating with the gripping grooves on both sides of the second type of groove. At the same time, the gripper moves the garlic seed to the top of the sowing mechanism. By driving the gripper to rotate, the garlic seed is rotated, so that the garlic seed is adjusted to a position with the root facing down and the bud facing up. Then the gripper is released and the garlic seed falls into the sowing mechanism.

[0018] 5. This invention uses multiple springs to clamp and limit the falling garlic seeds, keeping them in a downward-facing and upward-facing position. Then, as the pressing rod rotates, its upper groove engages with the upper part of the garlic seed in the corresponding cylinder. Furthermore, through the rotation of the elliptical cam and the second spring, the bearing seat moves back and forth, thereby driving the rotating shaft and the pressing rod to move back and forth in the direction of approaching and moving away from the sowing mechanism. This allows the end of the pressing rod to press the garlic seed into the soil in a near-vertical downward pressing state. With the assistance of the furrow opener, the roots of the garlic seed are inserted into the prepared furrow, and the garlic seed is buried under the action of the soil covering mechanism.

[0019] 6. The present invention drives the cam and the elliptical gear to rotate through the fourth power mechanism. The elliptical gear meshes with the second gear, which drives the rotating shaft to rotate. During the rotation of the cam, the second spring cooperates to realize the reciprocating movement of the rotating shaft, thereby realizing the reciprocating movement of the rotating shaft while rotating.

Detailed Implementation

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-16 As shown, this embodiment provides a garlic planting device, including a trolley 8 and a storage mechanism 1, a conveying mechanism 2, a posture adjustment mechanism 3, a planting mechanism 4, a pressing mechanism 5, a furrowing mechanism 6, and a soil covering mechanism 7 disposed on the trolley 8. The trolley 8 is provided with a corresponding driving mechanism for driving the trolley 8 to move. The driving mechanism adopts a motor or a motor + reducer structure.

[0038] The storage mechanism 1 is located above the conveying mechanism 2 and is used to store garlic seeds to be planted. The storage mechanism 1 is a funnel-shaped seed bin with a long strip opening on the lower side. The length of the long strip opening is consistent with the width of the conveying mechanism. Before planting, the selected garlic cloves that are uniform in size and plump are placed in the seed bin as garlic seeds to facilitate the subsequent planting work.

[0039] like Figures 4-6As shown, the storage mechanism 1 has a feeding mechanism at its lower end. This feeding mechanism is used to adjust the feeding posture and interval of the garlic seeds. The feeding mechanism includes a feeding cylinder 11 fixedly installed below the seed hopper and a feeding roller 12 rotatably installed inside the feeding cylinder 11. The feeding cylinder 11 has feeding holes 13 on both its upper and lower sides. The upper feeding hole 13 corresponds to and communicates with the lower opening of the seed hopper. The width of the feeding hole 13 corresponds to the thickness of the garlic seeds. The garlic seeds in the seed hopper can pass through the feeding hole 13 and contact the feeding roller 12. Limited by the width of the feeding hole 13, the passing garlic seeds undergo a first round of screening (the garlic seeds can only pass through the feeding hole 13 in a vertical position or with their length direction aligned with the length direction of the feeding hole 13). The feeding roller... Multiple first-type grooves 14 are equidistantly arranged around the feed roller 12. The first-type grooves 14 are elliptical grooves and their length direction is consistent with the axial direction of the feed roller 12. Furthermore, the first-type grooves 14 are set in multiple groups, and the multiple groups of first-type grooves 14 are arranged equidistantly along the axial direction of the feed roller 12. When one row of first-type grooves 14 rotates to correspond vertically with the feed hole 13, the garlic seed falls through the feed hole 13 located above and into the corresponding first-type groove 14. Based on the size of the first-type groove 14, each first-type groove 14 can hold one garlic seed. As the feed roller 12 continues to rotate, when the row of first-type grooves 14 corresponds to the feed hole 13 located below, the garlic seed falls onto the conveying mechanism 2 in an attitude where the width direction is consistent with the conveying direction and is conveyed backward.

[0040] As one possible implementation, the feeding cylinder 11 is preferably made of a smooth material, and there is a gap between the feeding roller 12 and the inner wall of the feeding cylinder 11. The gap is smaller than the thickness of the garlic seed. Furthermore, the sum of the depth of the first groove 14 and the gap corresponds to the thickness of the garlic seed to avoid squeezing the garlic seed.

[0041] A motor is fixedly installed at the end of the feeding cylinder 11 to drive the feeding roller 12 to rotate.

[0042] like Figure 16As shown, the conveying mechanism 2 is a belt conveyor. The conveyor belt of the conveying mechanism has multiple second-type grooves 21. The second-type grooves 21 are elliptical grooves and their length direction is consistent with the width direction of the conveyor belt. The second-type grooves 21 have the same structure as the first-type grooves 21. The second-type grooves 21 correspond vertically to the first-type grooves 14. Specifically, as the feeding roller 12 and the conveyor belt rotate, when each row of the first-type grooves 14 rotates to the point where the opening faces downward (i.e., corresponding vertically to the feeding hole 13 located below), a corresponding row of second-type grooves 21 will be conveyed to the area directly below the feeding hole 13. At this time, the row of the first-type grooves 14 and the row of the second-type grooves 21 correspond vertically and have opposite openings. Then, the garlic seeds in the first-type grooves 14 fall into the corresponding second-type grooves 21 under the action of gravity. The garlic seeds in the second-type grooves 21 are limited by the second-type grooves 21 so that their posture remains unchanged during the conveying process (i.e., they still maintain the posture where the length direction of the garlic seeds is consistent with the axial direction of the feeding roller 12, which is also the width direction of the conveyor belt).

[0043] As one possible implementation method, such as Figure 2 and Figure 7 As shown, the conveying mechanism 2 is a belt conveyor. A diverter and an interceptor are arranged above the conveying mechanism 2. Both the diverter and the interceptor are fixedly mounted on the trolley 8. There is a gap between the lower side of the diverter and the surface of the conveyor belt, and the gap is smaller than the thickness of the garlic seeds. The diverter is a V-shaped plate structure with its opening facing the end of the conveying mechanism 2. It is used to ensure that each column of garlic seeds is conveyed to the corresponding interceptor position. The interceptor is a U-shaped plate structure. The vertical plate of the U-shaped plate structure is fixedly connected to the opening end of the V-shaped plate structure. The length of the horizontal plate of the U-shaped plate is matched with or slightly greater than the length of the garlic seeds. When the garlic seeds are conveyed to the end of the conveying mechanism 2, they are blocked by the horizontal plate of the interceptor. If the garlic seeds tilt during the conveying process, their posture will be adjusted and restored under the friction of the conveyor belt after being blocked by the interceptor (i.e., the length direction of the garlic seeds is consistent with the width direction of the conveyor belt).

[0044] like Figure 7 As shown, a vision mechanism 9 is provided above the conveying mechanism 2 to identify the root orientation of the garlic seeds on the conveying mechanism 2. Furthermore, it can confirm whether there are any missing garlic seeds in each row. The vision mechanism 9 includes multiple cameras fixedly installed above the conveying mechanism 2. The cameras can be Gemini 345Lg binocular structured light cameras, which are used to identify the bud or root orientation of the garlic seeds conveyed by the conveying mechanism 2, providing support for further adjustment of the garlic seed posture.

[0045] The posture adjustment mechanism 3 is located between the conveying mechanism 2 and the sowing mechanism 4. The posture adjustment mechanism 3 is used to make the garlic seed roots fall downwards into the sowing mechanism 4. Figure 3 and Figures 8-9As shown, the attitude adjustment mechanism 3 includes a first slide rail 31, on which a first slider 32 is slidably mounted along the garlic conveying direction. Specifically, a bracket is fixedly mounted on the trolley 8, with the first slide rail 31 mounted on the upper end of the bracket. A corresponding driving component is also mounted on the bracket. The driving component can be a motor + screw structure or a cylinder, or any existing technology that enables the sliding of the first slider 32. The two ends of the first slide rail 31 are located above the end of the conveying mechanism 2 and above the sowing mechanism 4, respectively. A first power mechanism 33 is fixedly mounted on the first slider 32, and a rack 34 is slidably mounted vertically on it. Further, a frame is fixedly connected to the first slider 32, and a third slide rail is fixedly connected to one side of the frame. The rack 34 is slidably mounted vertically on the third slide rail, which limits the movement direction of the rack 34. The output end of the power mechanism 33 is connected to a first gear 35, which meshes with a rack 34. The first power mechanism 33 can be a motor or other existing technology that can drive the first gear 35 to rotate. By driving the first gear 35 to rotate, the rack 34 can be adjusted in height. A second power mechanism 36 is fixedly installed at the lower end of the rack 34. The output end of the second power mechanism 36 is connected to a swing block 37. The second power mechanism 36 can be a motor or other existing technology that can drive the swing block 37 to rotate. The swing direction of the lower end of the swing block 37 corresponds to the width direction of the conveying mechanism 2. A third power mechanism 38 and a gripper 39 are respectively installed on both sides of the lower end of the swing block 37. The third power mechanism 38 is used to drive the gripper 39 to open and close. The opening and closing direction of the gripper 39 corresponds to the conveying direction of the conveying mechanism 2.

[0046] The second type of groove 21 has symmetrical clamping grooves 22 on both sides of its middle section to accommodate the lower ends of the clamping claws 36 in the open state. The first slider 31 is driven to slide along the first slide rail 31 to above the end of the conveying mechanism 2. When the conveying mechanism 2 conveys a row of garlic seeds to below the clamping claws 39, the first power mechanism 33 drives the first gear 35 to rotate, causing the meshing rack 34 to rise and fall, thus lowering the clamping claws 39. Simultaneously, the third power mechanism 38 drives the clamping claws 39 to be in the open state, with the lower ends of the clamping claws 39 respectively located within the corresponding clamping grooves 22. When the garlic seed is in the second groove 21, the drive claw 39 closes and holds the garlic seed. Then the drive claw 39 and the rack 34 are raised and moved along the first slide rail 31 to the top of the corresponding sowing mechanism 4. The second power mechanism 36 drives the swing block 37 to rotate 90 degrees. Based on the direction of the root or bud of the garlic seed on the conveying mechanism 2 determined by the vision mechanism 9, the drive swing block 37 rotates in the corresponding direction. After the rotation is completed, the garlic seed is ensured to be in the state of root downward and bud upward. The claw 39 releases the grip and the garlic seed falls into the sowing mechanism 4.

[0047] The sowing mechanism 4 is located at the end of the conveying mechanism 2. The sowing mechanism 4 is used to ensure the falling posture of the garlic seeds and limit their movement. The sowing mechanism 4 includes multiple receiving hoppers 41 fixedly mounted on the trolley 8 and a cylinder 42 fixedly mounted and connected to the lower side of the receiving hoppers 41. Each receiving hopper 41 corresponds to a posture adjustment mechanism 3. Each posture adjustment mechanism 3 corresponds to a row of garlic seeds on the conveying mechanism 2. Each row of garlic seeds on the conveying mechanism 2 corresponds to a first type groove 14 around the circumference of the feeding roller 12. Furthermore, the spacing between two adjacent garlic seeds falling on the conveying mechanism 2 can be adjusted by adjusting the diameter of the feeding roller 12 or adjusting the number of first type grooves 14 around the feeding roller 12.

[0048] The inner circumference of the cylinder 42 is evenly distributed with spring plates 45. The upper and lower ends of the spring plates 45 are fixedly connected to the inner wall of the cylinder 42. A first spring 46 is fixedly installed between the inner side of the middle part of each spring plate 45 and the inner wall of the cylinder 42. After the gripper 39 is released, the garlic seed falls into the receiving hopper 41 and slides down the inner wall of the receiving hopper 41 into the cylinder 42. It still maintains the posture of the root facing down and the bud facing up, and is clamped and blocked by multiple spring plates 45, so that it cannot fall further.

[0049] The sowing mechanism 4 has a ditching mechanism 6 at the front of its lower end and a soil covering mechanism 7 at its rear of its lower end. The ditching mechanism 6 is used to dig trenches for planting garlic seeds. The ditching mechanism 6 includes a ditch opener fixedly installed at the front of the lower side of each sowing mechanism 4. The ditch opener corresponds to the strip hole 43. Specifically, the ditch opener can be a hoe or a simple ditching plow structure. As the trolley 8 moves forward, the trench can be dug.

[0050] The pressing mechanism 5 is located behind the sowing mechanism 4 and is used to press the garlic seeds in the sowing mechanism 4 downwards so that their roots are inserted into the soil. The pressing mechanism 5 includes a fourth power mechanism 51 fixedly mounted on the trolley 8. The output end of the fourth power mechanism 51 is fixedly connected to a cam 52 and an elliptical gear 53. The cam 52 is an elliptical wheel. The output end of the fourth power mechanism 51 is fixedly connected to the center position of the cam 52 and the elliptical gear 53. The fourth power mechanism 51 drives the cam and the elliptical gear 53 to rotate synchronously. Second slide rails 54 are fixedly mounted on both sides of the trolley 8. Bearing seats 55 are slidably mounted back and forth in the second slide rails 54. The rear end of the second slide rails 54 is fixedly mounted on... A baffle 56 is provided, and a second spring 57 is fixedly installed between the bearing seat 55 and the baffle 56. The cam 52 abuts against the corresponding bearing seat 55. Furthermore, each bearing seat 55 is located between the corresponding cam 52 and the second spring 57. As the cam 52 rotates and acts on the spring 57, it moves back and forth. A rotating shaft 58 is rotatably installed between the two bearing seats 55. The two ends of the rotating shaft 58 extend out of the corresponding bearing seats 55 and are fixedly connected to a second gear 59. The second gear 59 meshes with a corresponding elliptical gear 53. The elliptical gear 53 drives the second gear 59 to rotate, which in turn drives the rotating shaft 58 to rotate. A pressing rod 510 is symmetrically fixedly connected to the rotating shaft 58. Multiple rods 510 are provided. The receiving hopper 41 and the rear side of the cylinder 42 are provided with a connecting strip-shaped hole 43. The pressing rods 510 correspond to the strip-shaped holes 43 front and back. Specifically, each strip-shaped hole 43 has two pressing rods 510 symmetrically mounted on the rotating shaft 58. The free end of the pressing rod 510 has a groove 511. The groove 511 penetrates the end of the pressing rod 510 radially. The distance between the two opposite sidewalls of the groove 511 is less than the thickness of the garlic seed. As the pressing rod 510 rotates, its end extends into the corresponding strip-shaped hole 43, and its end groove 511 is engaged with the upper end of the garlic seed in the cylinder 42. Specifically, the bud end of the garlic seed extends upward out of the groove 511. 11. As the pressing rod 510 continues to rotate with the rotating shaft 58, and in conjunction with the back-and-forth sliding of the bearing seat 55, the groove 511 at the end of the pressing rod 510 presses the garlic seed downward in a near vertical downward pressing trend. During this process, the second spring 57 is compressed, and after the garlic seed moves down and leaves the cylinder 52, its root is inserted downward into the trench dug by the trench opener, completing the planting. As the pressing rod 510 continues to rotate, it moves away from the rear of the garlic seed. The lower rear end of the cylinder 42 is provided with an inverted V-shaped hole 44, which is connected to the corresponding strip hole 43. The inverted V-shaped hole 44 is designed to prevent the upper end of the planted garlic seed from colliding with the cylinder 42 as the trolley 8 moves forward.

[0051] The soil covering mechanism 7 is used to bury the planted garlic seeds. The soil covering mechanism 7 includes an installation rod 71 fixedly installed at the lower rear end of the trolley 8. A soil covering component corresponding to the front and rear of the trenching mechanism 6 is fixedly installed on the lower side of the installation rod 71. The soil covering component includes two soil covering plates 72. The two soil covering plates 72 are symmetrical about the corresponding trenching mechanism 6 and arranged in a figure-eight shape. The distance between the two soil covering plates 72 is greater than the thickness of the garlic seeds and the gap at their rear ends is smaller than the gap at their front ends. The installation rod 71 is bent between the two soil covering plates 72 of each soil covering component to avoid the rotating pressing rod 510 and avoid interference. As the trolley 8 moves forward, the soil squeezed out by the trencher and located on both sides of the trench is pushed back into the trench by the soil covering plates 72, completing the burial of the garlic seeds after planting, and thus completing the planting of garlic seeds. The burial depth can be adjusted by adjusting the height of the soil covering plates 72 to meet the requirements of garlic planting with the bud tip slightly exposed or covered with a thin layer of soil.

[0052] In use, firstly, select garlic cloves of uniform size and plumpness as garlic seeds and place them in the seed hopper. Simultaneously, drive the trolley 8 forward, driving the feeding roller 12 and conveying mechanism 2. As the feeding roller 12 rotates, when one row of the first type of groove 14 (to multiple first type grooves 14 corresponding to the axial direction of the feeding roller 12) rotates to align with the feeding hole 13, the garlic seeds pass through the upper feeding hole 13 and fall into the corresponding first type of groove 14. Limited by the width of the feeding hole 13, the passing garlic seeds undergo a first round of screening (garlic seeds can only pass through the feeding hole 13 in a vertical position or with their length direction aligned with the length direction of the feeding hole 13). As the feeding roller 12 continues to rotate, when the row of the first type of groove 14 aligns with the lower feeding hole 13, the garlic seeds fall into the corresponding second type of groove 21 on the conveying mechanism 2 with their width direction aligned with the conveying direction. During the conveying process, the vision mechanism 9 detects the movement. When the garlic seed is located in the second type of groove 21, the roots and buds are facing upwards. When the conveying mechanism 2 conveys a row of garlic seed to the area below the chuck 39, the first power mechanism 33 drives the first gear 35 to rotate, which drives the meshing rack 34 to rise and fall, causing the chuck 39 to fall. At the same time, the third power mechanism 38 drives the chuck 39 to be in an open state. When the lower end of the chuck 39 is located in the corresponding clamping groove 22, the chuck 39 is driven to close, clamping the garlic seed in the corresponding second type of groove 21. Then, the chuck 39 and rack 34 are driven to rise and move along the first slide rail 31 to the area above the corresponding planting mechanism 4. The second power mechanism 36 drives the swing block 37 to rotate 90 degrees. Based on the orientation of the roots or buds of the garlic seed on the conveying mechanism 2 determined by the vision mechanism 9, the swing block 37 is driven to rotate in the corresponding direction. After the rotation is completed, the garlic seed is ensured to be in a state where the roots are downwards and the buds are upwards. The chuck 39 releases its grip, and the garlic seed falls into the corresponding receiving hopper 41.

[0053] It should be noted that the furrow opener is located at the lower front of the cylinder 42, ensuring that the grooves opened by the cylinder 42 correspond vertically to those opened by the furrow opener. The fourth power mechanism 51 then drives the cam and oval gear 53 to rotate synchronously, causing the rotating shaft 58 to rotate and reciprocate back and forth. This, in turn, drives multiple pressing rods 510 to rotate. As the pressing rods 510 rotate, their ends extend into the corresponding slotted holes 43, and their end grooves 511 engage with the upper end of the garlic cloves inside the cylinder 42. Specifically, the bud end of the garlic cloves extends upwards out of the groove 511, and with the pressing rods... As the rotating shaft 58 continues to rotate, and in coordination with the back-and-forth movement of the rotating shaft 58, the groove 511 at the end of the pressing rod 510 presses the garlic seed downwards in a near-vertical downward pressing motion. During this process, the second spring 57 is compressed, and after the garlic seed moves down and detaches from the cylinder 52, its root is inserted downwards into the trench dug by the furrow opener, completing the planting. At the same time, as the trolley 8 moves, the covering plate 72 is inserted into the trench to bury the garlic seed, completing the planting of one row of garlic seeds. As the trolley 8 continues to move, the above process is repeated to realize the garlic planting work.
