Description

Technical Field

[0001] The invention relates to the technical field of garlic planting, in particular to a garlic sowing component and a use and adjustment method. Background Art

[0002] Garlic, a cash crop, is widely cultivated in northern my country. Currently, there are two main methods for garlic cultivation: manual cultivation and automated planting using mechanical equipment. Manual garlic cultivation requires prolonged squatting or bending, resulting in high labor intensity and low efficiency. Mechanized garlic cultivation also yields suboptimal results, and as a result, large-scale mechanized garlic cultivation has not yet taken off.

[0003] On September 11, 2020, the applicant applied for a technical solution entitled: "Garlic Planter Planting Mechanism" (Authorization Announcement No.: CN111642199B). In this technical solution, the seed pressing transmission chain rotates counterclockwise. During continuous garlic seed sowing, the garlic cloves that fall into the groove are gently tapped into the soil by the next seed pressing plate. During long-term use, the applicant discovered that the tapping of the garlic cloves by the seed pressing plate causes them to tilt to a certain extent. This tilting of the garlic cloves reduces the success rate of planting with the garlic buds facing upwards, thereby reducing the quality of the garlic cloves. Furthermore, on November 13, 2020, the applicant applied for a technical solution entitled: "Garlic Planter Single Seed Extraction Mechanism" (Authorization Announcement No.: CN111919559B). In this technical solution, the support plate of the garlic-picking mechanism and the receiving plate of the garlic cloves in the planting mechanism move in opposite directions in the garlic clove conveying transition area. In order to prevent interference between the support plate and the receiving plate during the actual processing, a large height difference is made between the support plate and the receiving plate in the garlic clove conveying transition area. The large height difference between the support plate and the receiving plate causes the garlic cloves to fall from the support plate to a higher height on the receiving plate. The large height difference in the falling height of the garlic cloves causes the garlic cloves to rebound more when they fall onto the receiving plate, which in turn causes the garlic to get stuck, making it impossible to carry out the normal garlic conveying process. Summary of the Invention

[0004] The object of the present invention is to provide a garlic sowing assembly, in which the garlic cloves will not be tapped during the planting process using a hole-digging plate in the sowing mechanism, thereby further improving the success rate of placing the garlic buds of the garlic cloves upward; at the same time, the height difference between the garlic seed spoon and the hole-digging plate is small, thereby reducing the rebound force of the garlic cloves after falling onto the hole-digging plate, reducing the occurrence of garlic sticking, and ensuring smooth transportation during the sowing process.

[0006] Preferably, the distance between the bottom of the seed removal chain and the top of the sowing chain is L1, and L1 is less than the sum of the heights of the garlic seed spoon and the digging plate.

[0007] Furthermore, the garlic sowing assembly also includes a garlic chopping shaft, a first power transmission mechanism, and a second power transmission mechanism. The garlic chopping shaft is arranged on the right side of the right side of the seed taking chain, and three flexible garlic chopping plates are arranged at equal intervals on the circumferential side wall of the garlic chopping shaft. The first power transmission mechanism can realize the counterclockwise rotation drive of the seed taking chain, and the second power transmission mechanism can drive the garlic chopping shaft to rotate clockwise. The first power transmission mechanism includes a first gear, and the second power transmission mechanism includes a second gear. The first gear can be engaged with and separated from the second gear. After the first gear is separated from the second gear, the initial swing position of the flexible garlic chopping plate can be adjusted by rotating the garlic chopping shaft.

[0008] Furthermore, when the flexible garlic chopping plate and the right side of the seed taking chain are perpendicular to each other, the distance between the outer end surface of the flexible garlic chopping plate and the right side of the seed taking chain is L2, 3mm≤L2≤5mm.

[0009] Furthermore, the garlic sowing assembly further includes a third power transmission mechanism, the first power transmission mechanism can drive the third power transmission mechanism to operate, and the third power transmission mechanism can drive the sowing chain to rotate clockwise.

[0010] Furthermore, the garlic sowing assembly also includes a garlic seed box, and the right side of the seed collection chain is located on the left side inside the garlic seed box.

Specifically, first, the seed taking chain and the garlic clove shaft are both in a stopped state, and then the first gear and the second gear are separated. After separation, the size of L3 is adjusted according to the size of the garlic seeds. When the size of the garlic seeds is small, the corresponding flexible garlic clove plate is swung counterclockwise by rotating the second gear, thereby reducing the adjustment of L3; when the size of the garlic seeds is large, the corresponding flexible garlic clove plate is swung clockwise by rotating the second gear, thereby increasing the adjustment of L3; Adjust the coordination between the garlic seed scoop and the digging plate; under the conditions that the linear speed of the seeding chain and the spacing between the garlic seed scoops are determined, the linear speed of the sowing chain and the spacing between the digging plates are reasonably set so that, under the conditions that the seeding chain and the sowing chain are in continuous operation, each digging plate can just receive a garlic clove that falls from the garlic seed scoop; During the garlic sowing process, the bottom of the sowing chain should be kept basically flush with the ground.

DETAILED DESCRIPTION

[0017] The following will be combined with specific embodiments and attached Figure 1-10 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the embodiments described are only some preferred embodiments of the present invention, not all embodiments. Those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] A garlic sowing component (such as Figure 1As shown), it includes a seeding chain 1 and a sowing chain 2. The seeding chain 1 and the sowing chain 2 are both improved from ordinary standard chains in the prior art, that is, the outer chain plates of the existing standard ordinary chains are replaced with L-shaped outer chain plates. Specifically, the outer chain plates of the seeding chain 1 are the first outer chain plates 12, and the outer chain plates of the sowing chain 2 are the second outer chain plates 22. The first outer chain plates 12 and the second outer chain plates 22 are both L-shaped, and the seeding chain 1 is distributed in a quadrilateral, and the left and right sides of the seeding chain 1 are distributed in a state where the upper part is tilted to the left relative to the bottom. The specific seeding chain 1 can use four sprockets distributed in a quadrilateral to achieve rotation support, and use one of them The drive of the sprocket can realize the rotation drive of the seed-taking chain 1; a plurality of garlic seed spoons 11 are arranged at equal intervals on the seed-taking chain 1, and one of the garlic seed spoons 11 is arranged on two opposite first outer chain plates 12. In actual application, the garlic seed spoon 11 is used to realize the extraction and transportation of single garlic cloves, which is convenient for the subsequent single-grain sowing of garlic. The size of the garlic seed spoon 11 is set according to the size of the existing single garlic clove; the sowing chain 2 is arranged at the lower left bottom of the seed-taking chain 1. Specifically, the sowing chain 2 is supported by two sprockets distributed relatively up and down, and the rotation of the sowing chain 2 is realized by driving one of the sprockets. 2 is provided with a plurality of digging plates 21 at equal intervals. In actual application, as the lower part of the digging plate 21 rotates in the soil, the action of digging holes in the soil is realized. As the digging plate 21 is driven and rotated, the garlic cloves on the digging plate 21 can just fall into the garlic holes dug by it, thereby facilitating the planting of garlic cloves. A first garlic clove adjustment cover 3 is provided on the left side of the left side of the seeding chain 1. A plurality of first through holes 31 are provided on the front and rear side walls of the first garlic clove adjustment cover 3. A first adjustment channel is formed between the first garlic clove adjustment cover 3 and the left side of the seeding chain 1. The first adjustment channel is in a vertical through-state and the garlic seed spoon 11 It can move in the first adjustment channel. In actual application, the first garlic clove adjustment cover 3 is used to adjust the garlic clove, that is, to place the garlic buds of the garlic cloves upward. Placing the garlic buds of the garlic cloves upward facilitates sowing the garlic buds upward in the subsequent sowing process. The specific structure and adjustment principle of the first garlic clove adjustment cover 3 can be referenced from the utility model patent with the authorization announcement number CN219741208U applied by the applicant in the early application. Therefore, the specific structure and working principle of the first garlic clove adjustment cover 3 are not described in detail here; the seed taking chain 1 and the sowing chain 2 move synchronously, that is, during the garlic sowing process, the seed taking chain 1 and the sowing chain 2 operate synchronously;The seeding chain 1 and the sowing chain 2 rotate counterclockwise and clockwise respectively, and a second garlic clove adjusting cover 4 is set on the right side of the right side of the sowing chain 2. Second through holes 41 are set on the front side wall and the rear side wall of the second garlic clove adjusting cover 4. The function of the second garlic clove adjusting cover 4 is the same as that of the first garlic clove adjusting cover 3, which is to realize the upward adjustment of the garlic buds. In actual application, the double adjustment process of the first garlic clove adjusting cover 3 and the second garlic clove adjusting cover 4 is utilized, which can greatly increase the probability of the garlic buds growing upward, and ultimately help to improve the success rate of the garlic buds growing upward; the interior of the second garlic clove adjusting cover 4 The spatial cross-section is a square with a side length of 30 mm; a second adjustment channel is formed between the second garlic clove adjustment cover 4 and the right side of the sowing chain 2, and the digging plate 21 can move in the second adjustment channel, and the garlic cloves flowing out from the bottom of the first adjustment channel can automatically fall into the second adjustment channel. In actual application, the garlic seed spoon 11 and a garlic clove located thereon move in the first adjustment channel. During the movement of the garlic clove, the adjustment effect of the first garlic clove adjustment cover 3 is used to realize the upward adjustment of the garlic bud. When individual garlic cloves fail to achieve adjustment in the first adjustment channel, they fall into the second adjustment channel. After entering the second adjustment channel, it is also adjusted again by the second garlic clove adjustment cover 4 as it and the corresponding digging plate 21 move downward synchronously; in actual application, the seeding chain 1 and the sowing chain 2 rotate counterclockwise and clockwise respectively, which can make the garlic seed spoon 11 at the bottom of the seeding chain 1 move from left to right, and at the same time make the digging plate 21 on the upper part of the sowing chain 2 also move from left to right. The movement directions of the garlic seed spoon 11 and the digging plate 21 are the same. After the moving speeds of the two are reasonably set, the two will not easily collide and interfere with each other; the sowing chain The digging plate 21 on the second garlic clove adjusting cover 4 is used to receive the garlic cloves delivered by the garlic seed spoon 11 on the seed retrieval chain 1. Therefore, if the garlic seed spoon 11 on the bottom of the seed retrieval chain 1 and the digging plate 21 on the top of the sowing chain 2 move in the same direction, the distance L1 between the bottom of the seed retrieval chain 1 and the top of the sowing chain 2 can be made smaller, thereby reducing the height difference when the garlic cloves fall from the garlic seed spoon 11 to the digging plate 21. The smaller the height difference when the garlic cloves fall, the less likely they will bounce around on the digging plate 21, and the less likely they will get stuck on the top of the second garlic clove adjusting cover 4, thereby ensuring the normal transportation of the garlic cloves. The bottom of the second garlic clove adjusting cover 4 is flush with or higher than the bottom of the sowing chain 2. In this specific embodiment, the bottom of the second garlic clove adjusting cover 4 is flush with the bottom of the sowing chain 2.

[0019] On the basis of the above embodiment, in order to minimize the height difference of the corresponding digging plate 21 when the garlic clove falls from the bottom of the first correction channel to the second correction channel, L1 can be made smaller than the sum of the heights of the garlic seed spoon 11 and the digging plate 21.

[0020] On the basis of the above embodiment, in order to improve the success rate of single garlic picking of the garlic seed spoon 11 during the garlic picking process, the garlic sowing assembly further includes a garlic clove shaft 81, a first power transmission mechanism, and a second power transmission mechanism. The garlic clove shaft 81 is arranged on the right side of the right side of the seed picking chain 1. Three flexible garlic clove plates 811 are evenly spaced on the circumferential side wall of the garlic clove shaft 81. The first power transmission mechanism can realize the counterclockwise rotation drive of the seed picking chain 1, and the second power transmission mechanism can drive the garlic clove shaft 81 to rotate clockwise. The principle of using the flexible garlic clove plates 811 to remove the excess garlic cloves 102 on the garlic seed spoon 11 is that when there are at least two or more garlic cloves on the garlic seed spoon 11, When the garlic cloves 102 are picked, as the garlic seed spoon 11 continuously moves with the garlic cloves 102 toward the flexible garlic clove plate 811, when the excess garlic cloves enter the effective garlic clove removal area earlier than the flexible garlic clove plate 811, the excess garlic cloves can be removed during the subsequent rotation of the flexible garlic clove plate 811, and then the single-grain seeding of the garlic seed spoon 11 can be achieved. The first power transmission mechanism includes a first gear 56, and the second power transmission mechanism includes a second gear 62. The first gear 56 can be engaged with and separated from the second gear 62. After the first gear 56 is separated from the second gear 62, the initial swing position of the flexible garlic clove plate 811 can be adjusted by rotating the garlic clove shaft 81. In actual application, the spacing of the garlic seed spoons 11 on the seed taking chain 1, the rotation linear speed of the seed taking chain 1 and the rotation angular speed of the garlic chopping shaft 81 are reasonably set, so that during the synchronous movement of the seed taking chain 1 and the garlic chopping shaft 81, the outer end of the corresponding flexible garlic chopping plate 811 can always be above the corresponding garlic seed spoon 11; in this specific embodiment, the number of teeth of the driving sprocket driving the seed taking chain 1 can be 18, and at the same time, a garlic seed spoon 11 is distributed on every six links of the seed taking chain 1, so that the driving sprocket driving the seed taking chain 1 and the angular speed of the garlic chopping shaft 81 are the same, so that during the continuous rotation of the seed taking chain 1 and the garlic chopping shaft 81, the flexible garlic chopping plate 811 and the corresponding garlic seed spoon 11 can maintain a relatively stable motion state. Figure 8As shown, when a flexible garlic chopping plate 811 moves to position A, a corresponding garlic seed spoon 11 happens to move to position B. During continuous operation, when the next flexible garlic chopping plate 811 happens to move to position A again, the next garlic seed spoon 11 also happens to move to position B again. Therefore, the size of L3 can be adjusted by utilizing the above-mentioned movement relationship between the flexible garlic chopping plate 811 and the garlic seed spoon 11. L3 is the distance between the flexible garlic chopping plate 811 with its outer end tilted downward and pointing to the right side of the seed removal chain 1 and the garlic seed spoon 11 below it. After L3 is adjusted, according to the characteristics of chain transmission and gear transmission, the size of L3 will basically not change during the subsequent continuous movement process, thereby achieving effective removal of excess garlic cloves or small garlic cloves during the single-grain seed removal process. The specific adjustment process of L3 is as follows: first, the seed-taking chain 1 and the garlic-cleaving shaft 81 are both in a stopped state, and then the first gear 56 is disengaged from the second gear 62. After the first gear 56 is disengaged from the second gear 62, the size of L3 is adjusted according to the size of the garlic seeds. When the size of the garlic seeds is small, the corresponding flexible garlic-cleaving plate 811 is swung counterclockwise by rotating the second gear 62, thereby reducing the adjustment of L3; when the size of the garlic seeds is large, the corresponding flexible garlic-cleaving plate 811 is swung clockwise by rotating the second gear 62, thereby increasing the adjustment of L3; after completing the size adjustment of L3, the first gear 56 is meshed with the second gear 62, thereby completing the size adjustment process of L3. The thickness and width of existing small garlic cloves are basically above 15 mm, and the thickness and width of garlic cloves are basically above 23 mm. Therefore, when adjusting the size of L3, the specific stacking form of the garlic cloves and the width and thickness values ​​of the garlic seeds can be adaptively adjusted according to the process of extracting garlic seeds or small garlic seeds by the garlic seed spoon 11, when at least two garlic seeds are taken at a time.

[0021] On the basis of the above embodiment, the specific implementation method of using the first power transmission mechanism and the second power transmission mechanism to realize the synchronous rotation of the seed chain 1 and the garlic shaft 81 is as follows: the first power transmission mechanism also includes a ground wheel 51, a first transmission shaft 52, a second transmission shaft 53, a third transmission shaft 54, and a fourth transmission shaft 55. The first transmission shaft 52, the second transmission shaft 53, the third transmission shaft 54 ​​and the fourth transmission shaft 55 are all rotatably arranged on the frame. The first transmission shaft 52 and the ground wheel 51 are powered by a first chain 58, and the first transmission shaft 52 and the second transmission shaft 53 and the third transmission shaft 54 ​​are powered by a second chain 59. The sprocket for rotating the seed chain 1 is sleeved on the second transmission shaft 53, and the fourth transmission shaft 55 includes a rotating sleeve 551 and a movable shaft 552. The movable shaft 552 is slidably sleeved on one side of the rotating sleeve 551, and the rotating sleeve 551 can drive the movable shaft 552 to rotate synchronously. The movable shaft 552 can slide back and forth and be positioned in the rotating sleeve 551. The first gear 56 is fixedly arranged at the front end of the movable shaft 552. In actual application, the relative sliding ability of the movable shaft 552 with respect to the rotating sleeve 551 can be used to realize the engagement and separation of the first gear 56 and the second gear 62; The front end of the sleeve 551 is sleeved with a spring 553, and the spring 553 is clamped between the front end of the rotating sleeve 551 and the rear end surface of the first gear 56. In actual application, when the first gear 56 is not subjected to external thrust, it moves to a position meshing with the second gear 62 under the push of the spring 553, thereby realizing power transmission between the first gear 56 and the second gear 62. Furthermore, the specific implementation method for the movable shaft 552 to achieve free sliding and positioning on the rotating sleeve 551 is as follows: the movable shaft 552 is a hexagonal stepped shaft, and the movable shaft 552 and the rotating sleeve 551 are matched in a hexagonal manner, which is convenient for ensuring that the rotating sleeve 551 and the movable shaft 552 are in engagement. 52, the large diameter portion 5521 of the movable shaft 552 is sleeved in the rotating sleeve 551, and the spring 553 is sleeved on the outside of the small diameter portion 25522 of the movable shaft 552, and a limiting ring 5511 is provided at the front end of the rotating sleeve 551, and the limiting ring 5511 is used to prevent the large diameter portion 5521 of the movable shaft 552 from extending out of the rotating sleeve 551, and then when the spring 553 is used to push the movable shaft 552 to extend out of the rotating sleeve 551, the limiting ring 5511 blocks the large diameter portion 5521, so as to prevent the movable shaft 552 from being separated from the rotating sleeve 551, thereby ensuring the matching stability of the first gear 56 and the second gear 62.The second power transmission mechanism also includes a fifth transmission shaft 61 and a sixth transmission shaft 63. The fifth transmission shaft 61 and the sixth transmission shaft 63 are both arranged on the frame. The second gear 62 is fixedly set on the fifth transmission shaft 61. Power transmission is achieved between the fifth transmission shaft 61, the garlic chopping shaft 81 and the sixth transmission shaft 63 through a fourth chain 64.

[0022] On the basis of the above embodiment, in order to ensure that the flexible garlic clove plate 811 can clearly remove excess garlic cloves, when the flexible garlic clove plate 811 and the right side of the seed-taking chain 1 are in a perpendicular state to each other, the distance between the outer end surface of the flexible garlic clove plate 811 and the right side of the seed-taking chain 1 is L2, 3mm≤L2≤5mm. The length of garlic cloves used as garlic seeds is generally more than 30mm, and the width and thickness are generally more than 15mm. Therefore, in this specific embodiment, the value of L2 can be set to 4mm. Since 4mm is much smaller than the thickness and width of the garlic cloves, even if the excess garlic cloves are lying flat against one side of the chain, the flexible garlic clove plate 811 can touch the excess garlic cloves during the rotation process, thereby ensuring the reliability of removing the excess garlic cloves.

[0023] On the basis of the above embodiment, the specific implementation method of the sowing chain 2 to achieve clockwise rotation is: the garlic sowing assembly also includes a third power transmission mechanism, the first power transmission mechanism can drive the third power transmission mechanism to operate, the third power transmission mechanism can drive the sowing chain 2 to rotate clockwise, the third power transmission mechanism includes a third gear 71, a fourth gear 72, and a seventh transmission shaft 73, the third gear 71 is fixedly provided on the third transmission shaft 54, the fourth gear 72 is fixedly provided on the seventh transmission shaft 73, the seventh transmission shaft 73 is provided on the frame, the sprocket that drives the sowing chain 2 to rotate is fixedly provided on the seventh transmission shaft 73, the third gear 71 and the fourth gear 72 are of the same model and are in a mutually meshed state, and during the rotation of the third transmission shaft 54, the rotation drive of the sowing chain 2 is realized.

[0024] On the basis of the above embodiment, in order to facilitate further covering of the upper part of the garlic cloves with soil after the garlic cloves are sown, a furrow opener 9 is provided on the left side of the left side of the sowing chain 2. The furrow opener 9 can open a groove of a certain depth, and the garlic cloves are planted in the groove, so that the soil on both sides of the groove can be used to cover the garlic cloves later.

[0025] In order to facilitate the continuous sowing of garlic cloves, the garlic sowing component further includes a garlic seed box 8. The right side of the seed removal chain 1 is located on the left side of the garlic seed box 8. In actual application, a certain amount of garlic cloves are prevented from being inside the garlic seed box 8. During the continuous operation of the seed removal chain 1, the garlic seed spoon 11 thereon is continuously moved out from the pile of garlic cloves inside the garlic seed box 8. When the garlic seed spoon 11 is moved out of the pile of garlic cloves, it will carry the garlic cloves with it, thereby achieving the removal of garlic cloves. When there are at least two garlic cloves on the garlic seed spoon 11, the flexible garlic-picking plate 811 is subsequently used to remove the garlic cloves, thereby finally achieving the removal of single garlic cloves from the garlic seed spoon 11.

[0026] When using the sowing chain 2 to sow garlic cloves, the following steps are taken: the digging plate 21 drags a garlic clove and moves continuously along the sowing chain 2 in the second correction channel. When the digging plate 21 moves to the bottom of the sowing chain 2, it moves in the direction pointing to the forward movement of the sowing mechanism. During the rotation of the digging plate 21, it will have a pushing effect on the soil. This pushing effect is used to realize the digging process in the soil 101. During the digging process, the garlic clove 102 on the digging plate 21 will automatically fall into the dug soil hole under the action of gravity. Because the garlic clove initially maintains a garlic bud upward state on the digging plate 21, after the garlic clove falls into the soil hole and separates from the digging plate 21, it can basically maintain a garlic bud upward state, thereby greatly improving the success rate of planting garlic cloves with garlic buds facing upward. When using the digging plate 21 to plant garlic cloves with the garlic buds facing upward, in order to further improve the success rate of the garlic buds facing upward, the digging plate 21 is made L-shaped, and the horizontal plate of the digging plate 21 211 is connected to the sowing chain 2, and the vertical plate 212 of the digging plate 21 is in the shape of a table tennis racket. The vertical plate 212 of the digging plate 21 is in the shape of a table tennis racket, so that during the rotation and pushing of the soil, the soil 102 around it is conducive to flowing into the soil hole area, and then the soil 101 can wrap the garlic clove 102 on the opposite side of the digging plate 21. At the same time, during the digging process, the soil on the front and back sides of the garlic clove 102 will automatically flow to the garlic clove 102 due to its automatic fluidity. 02, so that during the hole planting process, the left side, front side and right side of the garlic clove 102 will be partially wrapped by the soil 101 when it falls into the soil hole, which makes it easier to achieve the success rate of the garlic clove 102 falling into the soil hole and keeping the garlic sprout upward. At the same time, when one hole digging plate 21 is sowing garlic cloves, the adjacent hole digging plate 21 on its rear side will not contact the already planted garlic cloves when sowing subsequent garlic cloves, which is conducive to keeping the garlic sprouts of the garlic cloves upward for planting.

[0027] The present invention further provides a method for adjusting the use of a garlic sowing assembly, including the garlic sowing assembly described in the above embodiment, and the method further includes the following contents: Adjust the garlic clove spacing L3; reasonably set the spacing of the garlic seed spoons 11 on the seed taking chain 1, the rotation linear speed of the seed taking chain 1 and the rotation angular speed of the garlic clove shaft 81, so that during the synchronous movement of the seed taking chain 1 and the garlic clove shaft 81, the outer end of the corresponding flexible garlic clove plate 811 can always be above the corresponding garlic seed spoon 11; according to the size of the garlic seeds, adjust the spacing L3 between the flexible garlic clove plate 811 with its outer end tilted downward and pointing to the right side of the seed taking chain 1 and the garlic seed spoon 11 below it. Specifically, first First, the seed-taking chain 1 and the garlic-chopping shaft 81 are both stopped, and then the first gear 56 and the second gear 62 are separated. After separation, the size of L3 is adjusted according to the size of the garlic seeds. When the garlic seeds are small, the corresponding flexible garlic-chopping plate 811 is swung counterclockwise by rotating the second gear 62, thereby reducing the size of L3. When the garlic seeds are large, the corresponding flexible garlic-chopping plate 811 is swung clockwise by rotating the second gear 62, thereby increasing the size of L3. Adjust the coordination between the garlic seed spoon 11 and the hole-digging plate 21; under the conditions that the linear speed of the seed retrieval chain 1 and the spacing of the garlic seed spoon 11 are determined, the linear speed of the sowing chain 21 and the spacing of the hole-digging plates 21 are reasonably set so that, under the conditions that the seed retrieval chain 1 and the sowing chain 2 are in continuous operation, each of the hole-digging plates 21 can just receive a garlic clove dropped from the garlic seed spoon 11; that is, during the continuous rotation of the seed retrieval chain 1 and the sowing chain 2, each of the hole-digging plates 21 can just receive a garlic clove 102 when passing under the first correction channel, thereby ensuring the subsequent continuous planting of the garlic cloves; During the garlic sowing process, the bottom of the sowing chain 2 is kept substantially flush with the ground. The bottom of the sowing chain 2 is kept continuous with the ground, which can reduce the height at which the garlic cloves fall to the ground for planting and is also conducive to digging a soil hole of a certain depth using the digging plate 21. The small height difference of the garlic cloves falling to the ground makes it easier for the garlic cloves to keep the garlic buds upward as much as possible when they fall into the soil hole.

[0028] In the present invention, “left” and “right” are relative positions used for the convenience of describing positional relationships, and therefore cannot be understood as absolute positions to limit the scope of protection.
