Description

Technical Field

[0001] This invention relates to the field of garlic seed separation technology in garlic cultivation, specifically to a method for adjusting a novel single-seed extraction mechanism for garlic planting. Background Technology

[0002] Garlic is a widely cultivated cash crop in northern my country. Currently, there are two main methods of garlic cultivation: manual planting and automated planting using machinery. Manual garlic cultivation requires people to squat or bend over for extended periods, resulting in high labor intensity and low efficiency. Mechanized garlic cultivation has not yielded ideal results, thus large-scale mechanized garlic cultivation has not been widely developed.

[0003] On November 13, 2020, the applicant applied for a technical solution entitled "Single-Seed Extraction Mechanism for Garlic Planter" (Authorization Announcement No.: CN111919559B). This technical solution primarily utilizes the cooperation between flexible garlic-picking plates mounted on the first garlic-picking shaft 26 and the second garlic-picking shaft 29 and the corresponding support plate 4 to remove excess garlic seeds from the support plate 4, thereby significantly increasing the probability of having only one garlic clove on the support plate 4, thus enabling single-seed planting of garlic. However, in practical application, the applicant found that the different types of garlic grown by farmers resulted in different clove sizes. Some farmers' garlic cloves were larger than others. Because the relative position of the flexible garlic-picking plate and the tray 4 could not be easily changed once they were installed in the above technical solution, the flexible garlic-picking plate could not adapt well to the separation of garlic cloves of different sizes on the tray 4 in practical application. This reduced the probability that only one clove of a certain type of garlic would be on the tray 4, affecting the full promotion and application of the above seed-picking mechanism in the market. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustment method for a novel single-seed picking mechanism for garlic planting. This single-seed picking mechanism can ensure a high single-seed rate for garlic cloves of different sizes on the garlic seed spoon, thereby facilitating the full promotion and application of this single-seed picking mechanism in the market.

[0005] The technical solution adopted by this invention to solve its technical problem is: a novel single-seed extraction mechanism for garlic planting, comprising a seed extraction chain, a first power transmission mechanism, a garlic-picking shaft, and a second power transmission mechanism. A plurality of garlic seed scoops are evenly spaced on the seed extraction chain, which is quadrilateral in shape. The right side of the seed extraction chain is tilted to the left from the top relative to the bottom. The first power transmission mechanism enables the counterclockwise rotation of the seed extraction chain. The garlic-picking shaft is rotatably located on the right side of the right side of the seed extraction chain. A plurality of flexible garlic-picking plates are evenly spaced along the circumference of the garlic-picking shaft. The second power transmission mechanism enables the clockwise rotation of the garlic-picking shaft. The first power transmission mechanism includes a first gear, and the second power transmission mechanism includes a second gear. The first gear can engage and disengage with the second gear. After the first gear and the second gear disengage, the initial swing position of the flexible garlic-picking plates can be adjusted by rotating the garlic-picking shaft.

[0006] Preferably, when the flexible garlic-picking plate and the right side of the seed-taking chain are perpendicular to each other, the distance between the outer end face of the flexible garlic-picking plate and the right side of the seed-taking chain is L1, where 3mm≤L1≤5mm.

[0007] Furthermore, the first power transmission mechanism also includes a first transmission shaft and a second transmission shaft. The second transmission shaft is slidably sleeved on one side of the first transmission shaft. The first transmission shaft can drive the second transmission shaft to rotate synchronously. The second transmission shaft can slide back and forth and be positioned within the first transmission shaft. The first gear is fixedly disposed at the front end of the second transmission shaft. A spring is sleeved at the front end of the second transmission shaft. The spring is clamped between the front end of the first transmission shaft and the rear end face of the first gear.

[0008] Furthermore, the second drive shaft is a hexagonal stepped shaft, with the large-diameter portion of the second drive shaft fitted inside the first drive shaft. A limiting ring is provided at the front end of the first drive shaft to prevent the large-diameter portion of the second drive shaft from extending out of the first drive shaft.

[0009] Furthermore, the first power transmission mechanism includes a ground wheel, a third transmission shaft, and a fourth transmission shaft. The fourth transmission shaft transmits power to both the first and third transmission shafts via chain drive. The ground wheel transmits power to the third transmission shaft via chain drive. The fourth transmission shaft is equipped with a drive sprocket for driving the seed-collecting chain to rotate.

[0010] Furthermore, the second power transmission mechanism also includes a fifth transmission shaft, on which the second gear is mounted, and the power transmission between the fifth transmission shaft and the gear lever shaft is achieved by chain drive.

[0011] Furthermore, the single-seed extraction mechanism also includes a garlic seed box, with the right side of the extraction chain located inside the garlic seed box on the left side.

[0012] Furthermore, three flexible garlic-picking plates are evenly spaced on the garlic-picking shaft, and a V-shaped opening is provided at the middle of the outer end of each flexible garlic-picking plate.

[0013] A method for adjusting a novel single-seed picking mechanism for garlic planting, characterized in that it includes the novel single-seed picking mechanism for garlic planting according to claim 8, and the method further includes the following: reasonably setting the spacing of the garlic seed spoons on the seed picking chain, the rotational linear velocity of the seed picking chain and the rotational angular velocity of the garlic-picking shaft, so that during the synchronous movement of the seed picking chain and the garlic-picking shaft, the outer end of the corresponding flexible garlic-picking plate is always in the area above the corresponding garlic seed spoon.

[0014] Based on the size of the garlic cloves, the distance L2 between the flexible garlic-peeling plate (which is tilted downwards and points to the right side of the seed-picking chain) and the garlic-picking spoon below it is adjusted. Specifically, first, both the seed-picking chain and the garlic-peeling shaft are stopped. Then, the first gear is pushed forcefully to disengage from the second gear. After the first gear disengages from the second gear, L2 is adjusted according to the size of the garlic cloves. When the garlic cloves are small, the flexible garlic-peeling plate is rotated counterclockwise to reduce L2. When the garlic cloves are large, the flexible garlic-peeling plate is rotated clockwise to increase L2. After the L2 adjustment is completed, the push on the first gear is released, and the first gear re-engages with the second gear under the push of the spring, thus completing one adjustment process of L2.

[0015] The beneficial effects of this invention are: The invention has a simple structure and is easy to manufacture; in practical applications, the relative height difference between the flexible garlic-picking plate and the garlic seed spoon when stationary can be adjusted according to the size of the garlic cloves to be planted. A smaller height difference facilitates the flexible garlic-picking plate in removing excess small garlic cloves, while a larger height difference facilitates the removal of excess garlic cloves. This allows the invention to effectively extract individual seeds from garlic cloves of different sizes, thus facilitating single-seed planting of garlic. Simultaneously, it also facilitates the full market promotion of this invention. Applications: When adjusting the height difference between the flexible garlic-picking plate and the garlic seed spoon, simply push the first gear to separate it from the second gear. Then, rotate the second gear to adjust the rotation of the flexible garlic-picking plate, making the height difference adjustment operation convenient and quick. Simultaneously, when rotating the second gear, the rotation adjustment can be made according to the number of teeth it rotates relative to the first gear, thus facilitating visualization of the rotation adjustment. The V-shaped opening at the front of the flexible garlic-picking plate reduces the impact of the plate on the garlic cloves inside the garlic seed spoon, further increasing the single-seed picking probability of the garlic seed spoon.

Detailed Implementation

[0028] The following will describe specific embodiments and appendices. Figure 1-10 The technical solutions in the embodiments of the present invention are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of the present invention, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] This invention provides a novel single-seed harvesting mechanism for garlic planting (such as...). Figure 1As shown, the system includes a seed-harvesting chain 1, a first power transmission mechanism, a garlic-picking shaft 3, and a second power transmission mechanism. Several garlic seed scoops 11 are evenly spaced on the seed-harvesting chain 1. The seed-harvesting chain 1 is an improved version of a standard chain on the market. Specifically, the figure-eight outer chain plate of the existing standard chain is replaced with an L-shaped outer chain plate 12. The garlic seed scoops 11 are directly fixed to two L-shaped outer chain plates 12 facing each other by riveting. The seed-harvesting chain 1 is quadrilateral in shape, with the right side of the chain 1 tilted to the left from the top relative to the bottom. The first power transmission mechanism drives the seed-harvesting chain 1 to rotate counterclockwise. During this counterclockwise rotation, the garlic seed scoops 11 move upwards along the right side of the chain 1, facilitating the harvesting of garlic seeds. For picking and transporting, the garlic-picking shaft 3 is rotatably mounted on the right side of the right side of the seed-picking chain 1. Several flexible garlic-picking plates 31 are evenly spaced along the circumference of the garlic-picking shaft 3. The second power transmission mechanism enables the clockwise rotation of the garlic-picking shaft 3. The first power transmission mechanism includes a first gear 21, and the second power transmission mechanism includes a second gear 41. The first gear 21 can mesh with and disengage from the second gear 41. That is, when the first gear 21 and the second gear 41 mesh, the first power transmission mechanism and the second power transmission mechanism are connected. When the first gear 21 and the second gear 41 disengage, the first power transmission mechanism and the second power transmission mechanism are disengaged. After the first gear 21 and the second gear 41 disengage, the initial swing position of the flexible garlic-picking plates 31 can be adjusted by rotating the garlic-picking shaft 3. In practical applications, by adjusting the relative height difference between the flexible garlic-picking plate 31 and the corresponding garlic seed spoon 11, the flexible garlic-picking plate 31 can adapt to the removal of excess garlic cloves of different sizes on the garlic seed spoon 11, thereby ensuring the success rate of single-seed extraction of garlic cloves of different sizes by the garlic seed spoon 11, which facilitates the promotion and application of this invention in the market.

[0030] Based on the above embodiments, to improve the reliability of the flexible garlic-removing plate 31 in removing excess garlic cloves from the garlic seed spoon 11, such as... Figure 3As shown, when the flexible garlic-picking plate 31 and the right side of the seed-taking chain 1 are perpendicular to each other, the distance between the outer end face of the flexible garlic-picking plate 31 and the right side of the seed-taking chain is L1, where 3mm≤L1≤5mm. The length of garlic cloves used as seeds is generally more than 30mm, and the width and thickness are generally more than 15mm. Therefore, in this specific embodiment, the value of L1 can be set to 4mm. Since 4mm is much smaller than the thickness and width of garlic cloves, even if excess garlic cloves are lying flat against one side of the chain, the flexible garlic-picking plate 31 can still touch the excess garlic cloves during rotation, thereby ensuring the reliability of removing excess garlic cloves.

[0031] Based on the above embodiments, the specific implementation method for enabling the first gear 21 and the second gear 41 to mesh and disengage is as follows: The first power transmission mechanism further includes a first transmission shaft 22 and a second transmission shaft 23. The second transmission shaft 23 is slidably sleeved on one side of the first transmission shaft 22. The first transmission shaft 22 can drive the second transmission shaft 23 to rotate synchronously. The second transmission shaft 23 can slide back and forth and be positioned within the first transmission shaft 22. The first gear 21 is fixedly disposed at the front end of the second transmission shaft 23. In practical applications, the meshing and disengagement of the first gear 21 and the second gear 41 can be achieved by utilizing the relative sliding ability of the second transmission shaft 23 relative to the first transmission shaft 22. A spring 24 is sleeved at the front end of the second transmission shaft 23. The spring 24 is clamped between the front end of the first transmission shaft 22 and the rear end face of the first gear 21. In practical applications, when the first gear 21 is not subjected to external thrust, it moves under the push of the spring 24 to mesh with the second gear 41. The position allows for power transmission between the first gear 21 and the second gear 41. Further, the specific implementation of the free sliding and positioning of the second transmission shaft 23 on the first transmission shaft 22 is as follows: the second transmission shaft 23 is a hexagonal stepped shaft. The hexagonal fit between the second transmission shaft 23 and the first transmission shaft 22 facilitates synchronous movement between them. The large-diameter portion 231 of the second transmission shaft 23 is fitted inside the first transmission shaft 22, and the spring 24 is fitted outside the small-diameter portion 232 of the second transmission shaft 23. A limiting ring 221 is provided at the front end of the first transmission shaft 22. The limiting ring 221 prevents the large-diameter portion 231 of the second transmission shaft 23 from extending out of the first transmission shaft 22. Then, when the spring 24 pushes the second transmission shaft 23 out of the first transmission shaft 22, the limiting ring 21's obstruction of the large-diameter portion 231 prevents the second transmission shaft 23 from disengaging from the first transmission shaft 22, thus ensuring the stability of the fit between the first gear 21 and the second gear 41.

[0032] Based on the above embodiments, the specific implementation of the first power transmission mechanism is as follows: The first power transmission mechanism includes a ground wheel 25, a third transmission shaft 26, and a fourth transmission shaft 27. The ground wheel 25 is used to roll on the ground. In practical applications, when the entire mechanism is driven to move on the ground by a traction mechanism, the ground wheel 25 rolls synchronously. The third transmission shaft 26 and the fourth transmission shaft 27 are both rotatably mounted on the frame. The fourth transmission shaft 27 transmits power to the first transmission shaft 22 and the third transmission shaft 26 through chain drives. Specifically, a twelfth sprocket 112 is provided at the rear end of the first transmission shaft 22, and a sixth sprocket 106 is provided at the rear end of the fourth transmission shaft 27. A third chain 203 is sleeved between the twelfth sprocket 112 and the sixth sprocket 106. The third chain 203 is used to realize the power transmission between the first transmission shaft 22 and the fourth transmission shaft 27. A fourth sprocket 104 is provided at the front end of the fourth transmission shaft 27, and a third sprocket 103 is provided at the rear end of the third transmission shaft 26. A second chain 202 is fitted onto the fourth sprocket 104, the third sprocket 103, and the thirteenth sprocket 113, forming a triangular distribution. The second chain 202 is used to transmit power between the third drive shaft 26 and the fourth drive shaft 27. The ground wheel 25 transmits power to the third drive shaft 26 via a chain drive. Specifically, a first sprocket 101 is positioned at the front end of the rotating shaft of the ground wheel 25, and a second sprocket 102 is positioned at the front end of the third drive shaft 26. The first sprocket 101 and the second sprocket... A first chain 201 is fitted between the ground wheel 25 and the third drive shaft 26. The first chain 201 enables power transmission between the ground wheel 25 and the third drive shaft 26. A drive sprocket for rotating the seed-collecting chain 1 is mounted on the fourth drive shaft 27. Specifically, a fifth sprocket 105 is positioned in the middle of the fourth drive shaft 27. The fifth sprocket 105 and three seventh sprockets 107 form a quadrilateral structure. The seed-collecting chain 1 is fitted onto the fifth sprocket 105 and the three seventh sprockets 107, thus achieving a quadrilateral distribution. In practical application, when the ground wheel 25 rotates on the ground, the synchronous rotation of the seed-collecting chain 1 and the first gear 21 is achieved through the power transmission of the first chain 201, the second chain 202, and the third chain 203.

[0033] Based on the above embodiments, the specific implementation of the second power transmission mechanism is as follows: the second power transmission mechanism further includes a fifth transmission shaft 42, the second gear 41 is disposed on the fifth transmission shaft 41, and the power transmission between the fifth transmission shaft 42 and the garlic-picking shaft 3 is achieved by chain drive. Further, the single-seed extraction mechanism also includes a garlic seed box 5, the right side of the seed extraction chain 1 is located on the left side inside the garlic seed box 5, both the fifth transmission shaft 42 and the garlic seed box 5 are disposed on the frame, the garlic-picking shaft 3 is disposed on the left side inside the garlic seed box 5, and an eighth sprocket 108 is disposed at the front end of the garlic-picking shaft 3. An eleventh sprocket 111 is installed on the upper part of the second gear 41, and a ninth sprocket 109 is installed below the garlic seed box 5. The ninth sprocket 109 is mounted on a drive shaft 6. A fourth chain 204 is mounted on the eleventh sprocket 111, the eighth sprocket 108, and the ninth sprocket 109. At the same time, a tenth sprocket 110 is installed on the side wall of the garlic seed box 5 to realize the tension of the fourth chain 204. The fourth chain 204 is used to realize the power transmission between the fifth drive shaft 42 and the garlic-pulling shaft 3. The meshing of the first gear 21 and the second gear 41 realizes the power transmission between the first power transmission mechanism and the second power transmission mechanism. In practical applications, a large number of garlic cloves are placed in the garlic seed box 5. When the garlic seed spoon 11 continuously extracts garlic cloves one by one from the garlic seed box 5, in order to prevent the garlic cloves in the garlic seed box 5 from being emptied, a rocker that can swing up and down is set at the bottom of the garlic seed box 5. A triangular plate 61 is set on the actuating shaft 6. As the triangular plate 61 rotates continuously, the rocker is continuously moved up and down, thereby moving the garlic cloves in the garlic seed box 5, which can effectively prevent the material from being emptied in the garlic seed box 5.

[0034] In practical applications, when the first gear 21 and the second gear 41 are engaged, the ground wheel 25 rolls, driving the seed-taking chain 1 and the garlic-picking shaft 3 to move synchronously. When the first gear 21 and the second gear 41 are disengaged, the rolling of the ground wheel 25 cannot drive the rotation of the garlic-picking shaft 3. At the same time, when the first gear 21 and the second gear 41 are disengaged, the garlic-picking shaft 3 can be rotated independently by rotating the second gear 41. This allows the initial position of the flexible garlic-picking plate 31 relative to the corresponding garlic seed spoon 11 to be changed, thereby adjusting the relative height difference between the flexible garlic-picking plate 31 and the garlic seed spoon 11. This enables the flexible garlic-picking plate 31 to effectively remove excess garlic cloves of different sizes.

[0035] Based on the above embodiments, the specific implementation of the flexible garlic-picking plate 31 on the garlic-picking shaft 3 is as follows: three flexible garlic-picking plates 31 are equally spaced on the garlic-picking shaft 3, and a V-shaped opening 311 is provided at the middle of the outer end of each flexible garlic-picking plate 31.

[0036] like Figure 4 As shown, it illustrates the relative motion relationship between the flexible garlic-dispensing plate 31 and the garlic seed spoon 11. Since the flexible garlic-dispensing plate 31 always moves in a circular motion around the garlic-dispensing axis 3, it can be determined that the area covered by the flexible garlic-dispensing plate 31 after one revolution is a circular area. The garlic seed spoon 11 always moves in a straight line on the right side of the seed-taking chain 1, which makes the movement distribution area of ​​the garlic seeds 401 on the garlic seed spoon 11 a rectangular area. The width of the rectangular area is basically the same as the width of the garlic seed spoon 11. Therefore, it can be concluded that there is an effective garlic seed contact and dispensing area 302 in the part where the circular area and the rectangular area overlap. That is, the overlapping area of ​​the circular area and the rectangular area is located in the lower part of the vertical line 301 between the garlic-dispensing axis 3 and the seed-taking chain 1. In actual operation, only when the component of velocity of the flexible garlic-picking plate 31 along the direction of the garlic seed chain 1 is equal to or greater than the velocity of the garlic seed spoon 11 during its upward rotation relative to the garlic seed spoon 11 can the flexible garlic-picking plate 31 be guaranteed not to interfere with the garlic seed spoon 11 during its movement, thereby achieving a stable garlic seed removal process. After setting the linear velocity of the garlic seed spoon 11 and the rotational angular velocity of the garlic-picking shaft 3, the flexible garlic-picking plate 11 and the garlic-picking plate 3 maintain a relatively stable motion state to remove excess garlic seeds. During the single-seed extraction process, only when the excess garlic seed 401 on the garlic seed spoon 11 reaches the effective contact and removal area 302 of the garlic seed before the flexible garlic-picking plate 31 (e.g., Figure 6 As shown), with the continued movement of the garlic seed spoon 11 and the flexible garlic-removing plate 31, excess garlic seeds can be removed. When the excess garlic seeds 401 on the garlic seed spoon 11 arrive at the effective contact and removal area 302 of the garlic seeds later than the flexible garlic-removing plate 31 (as shown), Figure 5As shown), the flexible garlic-removing plate 31 cannot remove excess garlic seeds. After the moving speed of the garlic seed spoon 11 and the angular velocity of the flexible garlic-removing plate 31 are reasonably set, the relative height difference L2 between the garlic seed spoon 11 and the flexible garlic-removing plate 31 when they are stationary determines whether the excess garlic seeds 401 on the garlic seed spoon 11 will enter the effective contact and removal area 302 of garlic seeds in advance compared to the flexible garlic-removing plate 31. In practical applications, if L2 is less than the thickness of an excess garlic seed, then when the flexible garlic-removing plate 31 moves to the starting position of the effective contact and removal area 302, the upper part of the excess garlic seed 401 has already entered the effective contact and removal area 302, and can then be removed using the flexible garlic-removing plate 31. If L2 is much larger than the thickness of an excess garlic seed, then when the flexible garlic-removing plate 31 moves to the starting position of the effective contact and removal area 302, the upper part of the excess garlic seed 401 has not yet entered the effective contact and removal area 302, and cannot then be removed using the flexible garlic-removing plate 31. Therefore, the relationship between L2 and the thickness of the excess garlic seed 401 is the key factor in whether the excess garlic seed can be removed.

[0037] like Figure 7 As shown, while the flexible garlic-removing plate 31 can effectively remove excess garlic seeds 402, it may not be able to effectively remove excess small garlic seeds 403. This is because the set value L2 is much larger than the thickness of the excess small garlic seeds 403 when removing garlic seeds, thus preventing the effective removal of the excess small garlic seeds 403. In this case, only by appropriately adjusting L2 to be smaller than the thickness of the excess small garlic seeds 403 can the excess small garlic seeds 403 be removed. Under the condition of removing the excess small garlic seeds 403, the removal of excess garlic seeds 402 can basically be achieved. However, at this time, the flexible garlic-removing plate 31 may remove all the garlic seeds on the garlic seed spoon 11 at the same time. Therefore, when removing garlic seeds 401 of different sizes, the distance L2 should be adjusted according to the size of the garlic seeds to ensure effective single-seed removal of garlic seeds of different sizes.

[0038] This invention also improves the adjustment method of a novel single-seed picking mechanism for garlic planting, including the novel single-seed picking mechanism for garlic planting described in the above embodiments. The adjustment method further includes the following: reasonably setting the spacing of the garlic seed scoops 11 on the seed picking chain 1, the linear velocity of the rotation of the seed picking chain 1, and the angular velocity of the garlic-picking shaft 3, so that during the synchronous movement of the seed picking chain 1 and the garlic-picking shaft 3, the outer end of the corresponding flexible garlic-picking plate 31 is always above the corresponding garlic seed scoop 11. In this specific embodiment, the fifth sprocket 105 can have 18 teeth, and one garlic seed scoop 11 can be distributed on every six links of the seed picking chain 1, so that the angular velocity of the fifth sprocket 105 is the same as the angular velocity of the garlic-picking shaft 3. This allows the flexible garlic-picking plate 31 and the corresponding garlic seed scoop 11 to maintain a relatively stable motion state during the continuous rotation of the seed picking chain 1 and the garlic-picking shaft 3. Figure 4 As shown, when a flexible garlic-picking plate 31 moves to position A, a corresponding garlic seed spoon 11 moves to position B. During continuous operation, when the next flexible garlic-picking plate 31 moves to position A again, the next garlic seed spoon 11 also moves to position B again. By utilizing the above-mentioned movement relationship between the flexible garlic-picking plate 31 and the garlic seed spoon 11, the size of L2 can be adjusted. After L2 is adjusted, based on the characteristics of chain drive and gear drive, it can be known that the size of L2 will not change much during subsequent continuous movement, thereby achieving effective removal of excess garlic cloves or small garlic cloves during the single-seed picking process.

[0039] Based on the size of the garlic cloves, the distance L2 between the flexible garlic-picking plate 31, which is tilted downwards and points to the right side of the seed-picking chain 1, and the garlic clove spoon 11 below it is adjusted. Specifically, firstly, both the seed-picking chain 1 and the garlic-picking shaft 3 are stopped. Then, the first gear 21 is pushed forcefully to disengage from the second gear 41. After the first gear 21 disengages from the second gear 41, the size of L2 is adjusted according to the size of the garlic cloves. When the garlic cloves are small, the flexible garlic-picking plate 31 is rotated counterclockwise by rotating the second gear 41, thereby reducing L2. When the garlic cloves are large, the flexible garlic-picking plate 31 is rotated clockwise by rotating the second gear 41, thereby increasing L2. After the size adjustment of L2 is completed, the push on the first gear is released, and the first gear 21 re-engages with the second gear 41 under the push of the spring 24, thus completing one adjustment process of L2. The thickness and width of existing small garlic cloves are basically above 15mm, and the thickness and width of garlic cloves are basically above 23mm. Therefore, when adjusting the size of L2, the specific stacking form of garlic cloves and the width and thickness values ​​of garlic cloves can be adjusted according to the process of extracting garlic cloves 402 or small garlic cloves 403 by garlic clove spoon 11 when at least two garlic cloves are taken at one time.

[0040] In this invention, "left" and "right" are relative positions used for the convenience of describing positional relationships, and therefore should not be interpreted as absolute positions or as limitations on the scope of protection.

[0041] Except for the technical features described in the specification, all other technologies are known to those skilled in the art.

A spring is sleeved at the front end of the second transmission shaft. The spring is clamped between the front end of the first transmission shaft and the rear end face of the first gear.

4. The novel single-seed harvesting mechanism for garlic planting according to claim 3, characterized in that, The second drive shaft is a hexagonal stepped shaft. The large diameter portion of the second drive shaft is fitted inside the first drive shaft. A limiting ring is provided at the front end of the first drive shaft. The limiting ring is used to prevent the large diameter portion of the second drive shaft from extending out of the first drive shaft.

5. The novel single-seed harvesting mechanism for garlic planting according to any one of claims 4, characterized in that, The first power transmission mechanism includes a ground wheel, a third transmission shaft, and a fourth transmission shaft. The fourth transmission shaft transmits power to both the first and third transmission shafts via chain drive. The ground wheel transmits power to the third transmission shaft via chain drive. The fourth transmission shaft is equipped with a drive sprocket for driving the seed-collecting chain to rotate.

6. The novel single-seed harvesting mechanism for garlic planting according to claim 4, characterized in that, The second power transmission mechanism also includes a fifth transmission shaft, on which the second gear is mounted. Power transmission between the fifth transmission shaft and the shovel shaft is achieved by chain drive.

7. The novel single-seed harvesting mechanism for garlic planting according to claim 4, characterized in that, The single-seed extraction mechanism also includes a garlic seed box, with the right side of the extraction chain located inside the garlic seed box on the left side.

8. The novel single-seed harvesting mechanism for garlic planting according to claim 4, characterized in that, in The garlic-peeling shaft is provided with three flexible garlic-peeling plates at equal intervals, and a V-shaped opening is provided at the middle of the outer end of each flexible garlic-peeling plate.

9. A method for adjusting a novel single-seed harvesting mechanism for garlic planting, characterized in that, The method of adjusting the garlic planting single-seed picking mechanism according to claim 8 further includes the following: reasonably setting the spacing of the garlic seed spoons on the seed picking chain, the rotational linear speed of the seed picking chain and the rotational angular velocity of the garlic picking shaft, so that during the synchronous movement of the seed picking chain and the garlic picking shaft, the outer end of the corresponding flexible garlic picking plate can always be in the area above the corresponding garlic seed spoon. Based on the size of the garlic cloves, the distance L2 between the flexible garlic-peeling plate (which is tilted downwards and points to the right side of the seed-picking chain) and the garlic-picking spoon below it is adjusted. Specifically, first, both the seed-picking chain and the garlic-peeling shaft are stopped. Then, the first gear is pushed forcefully to disengage from the second gear. After the first gear disengages from the second gear, L2 is adjusted according to the size of the garlic cloves. When the garlic cloves are small, the flexible garlic-peeling plate is rotated counterclockwise to reduce L2. When the garlic cloves are large, the flexible garlic-peeling plate is rotated clockwise to increase L2. After the L2 adjustment is completed, the push on the first gear is released, and the first gear re-engages with the second gear under the push of the spring, thus completing one adjustment process of L2.
