Description

Technical Field

[0001] The invention relates to the field of garlic harvesters, and in particular to a garlic lodging and straightening synchronous harvesting front device and a harvesting method. Background Art

[0002] The self-propelled garlic combine harvesters currently available on the market can complete the combined operations of garlic separation, digging, clamping and separation of garlic heads and vines at one time. During the garlic harvesting process, issues such as harvesting speed, damage rate, and missed harvesting rate need to be considered. The appropriate harvesting speed can ensure that the garlic is harvested at the best harvesting period and reduce the risk of being attacked by rain, pests and diseases. During the harvesting process, the damage rate should be reduced as much as possible to keep the garlic intact to reduce the risk of pathogen invasion and rot caused by damage. Reducing the missed harvesting rate can ensure maximum yield and reduce the impact on the planting and growth of the next crop.

[0003] A Chinese patent (publication number CN 108200795 A, publication date 20180626) discloses a garlic digging and stripping machine, which can effectively dig garlic plants and clamp and transport them to one side of the machine. The vibration digging resistance is small and the soil penetration effect is good. The garlic plant clamping process is continuous and reliable. Among them, a grass-dividing and guiding device for straightening and guiding the fallen garlic vines is provided at the front of the frame. The garlic to be harvested in front of the frame is guided by the grass-dividing and guiding device. The garlic vines that deviate from the planting ridges can be gathered so that the garlic vines can contact the clamping device, but it can only guide the crooked garlic vines. For garlic that falls due to environmental factors such as weather, its grass-dividing and guiding device cannot effectively guide the fallen garlic that is close to the ground, making it difficult to enter the subsequent clamping working end, resulting in missed harvesting, increasing the missed harvesting rate when harvesting garlic, and it is difficult to solve the problem of reduced yield due to the high missed harvesting rate and affecting the planting of the next crop. Summary of the invention

[0004] The purpose of the present invention is to provide a garlic lodging and straightening synchronous harvesting pre-device and a harvesting method in view of the defects in the prior art. Through a series of structural designs, the lodging garlic can be straightened and transported so that it can smoothly enter the subsequent harvesting process, reduce the missed harvest rate, improve the integrity of the garlic harvest, ensure the garlic yield, and avoid potential interference with the planting of the next crop.

[0005] The first object of the present invention is to provide a garlic lodging and straightening synchronous harvesting pre-device, which adopts the following scheme:

[0006] It comprises a straightening shovel, at least two of which are arranged in parallel, and a conveying channel is formed between adjacent straightening shovels; along the moving direction of the garlic sprouts in the conveying channel, the conveying channel is divided into a straightening section and a separation section, at least two straightening wheels are alternately arranged on the straightening shovels on both sides of the straightening section, the straightening wheels are rotatably installed on the straightening shovel, and the straightening wheels are provided with hook grooves for grabbing the garlic sprouts, the reciprocating swinging motion paths of adjacent straightening wheels partially overlap, and the garlic sprouts grabbed by the hook grooves are transferred between adjacent straightening wheels through the overlapping position of the hook groove motion paths, and the hook groove of the straightening wheel located at the end of the straightening section is connected with the separation section to transfer the garlic sprouts to the separation section.

[0007] Furthermore, along the direction from the straightening section to the separation section, the hook groove of the straightening wheel located at the head end of the straightening section can extend out of the conveying channel, so that the hook groove can penetrate into the planting soil layer to grab the garlic seedlings.

[0008] Furthermore, there are three straightening wheels, namely a first-stage straightening wheel, a second-stage straightening wheel and a third-stage straightening wheel, and the hook grooves on the first-stage straightening wheel, the second-stage straightening wheel and the third-stage straightening wheel are connected in sequence.

[0009] Furthermore, along the direction from the straightening section to the separation section, adjacent straightening wheels are staggered in the direction of their rotation axes.

[0010] Furthermore, it also includes a digging shovel located below the straightening shovel. At least two digging shovels are arranged in parallel. A digging channel is formed between adjacent digging shovels. Along the conveying direction of the garlic sprouts carried by the digging shovel, the digging channel is divided into a digging section and a clamping section. Augers are provided on the digging shovels on both sides of the clamping section.

[0011] Furthermore, the front end of the digging shovel extends to below the straightening wheel at the end of the straightening section to receive the bottom end of the garlic sprouts grasped by the straightening wheel.

[0012] Furthermore, the clamping section and the digging section are arranged obliquely, and the digging section and the clamping end are set at different inclinations relative to the horizontal plane.

[0013] Furthermore, in the vertical direction, the conveying channel and the excavation channel are distributed in the same plane.

[0014] The second object of the present invention is to provide a harvesting method of garlic lodging and straightening synchronous harvesting pre-device as described in the first object, comprising:

[0015] Move to the garlic seedling planting ridge position, and harvest along the planting ridge;

[0016] The straightening wheel at the front end of the straightening section swings and partially penetrates into the planting soil layer, and then uses the hook groove to grab the fallen garlic seedlings. The fallen garlic seedlings after being hooked up rotate with the straightening wheel, so that the fallen garlic seedlings enter the conveying channel;

[0017] The straightening wheel at the next level swings, and when the two adjacent straightening wheels swing until the hook grooves overlap, the straightening wheel at the upper level swings in the opposite direction, and the straightening wheel at the lower level continues to swing, so that the garlic seedlings are transferred between the straightening wheels at different levels; the straightening wheels swing in sequence to transfer the garlic seedlings;

[0018] Until it is transferred to the straightening wheel at the end of the straightening section, the garlic sprouts caught by the hook groove of the straightening wheel are transferred to the separation section;

[0019] Through the separation section it enters the subsequent process of the harvesting equipment.

[0020] Furthermore, the straightening wheel swings back and forth, grabs the garlic seedlings distributed on the garlic seedling planting ridges one by one and transports them to the separation section.

[0021] Compared with the prior art, the present invention has the following advantages and positive effects:

[0022] In view of the problem that the current garlic harvesting equipment can only guide the crooked garlic seedlings but cannot effectively guide the garlic that has fallen down on the ground, resulting in a high missed harvest rate, a parallel straightening shovel is arranged to provide structural support and a conveying channel for the entire device. The conveying channel is a moving planning route for the garlic seedlings, so that the garlic seedlings can move along the set direction, which is convenient for subsequent straightening, conveying and other operations on the garlic seedlings; at least two straightening wheels are alternately arranged on the straightening shovels on both sides of the straightening section, the reciprocating swinging motion paths of adjacent straightening wheels partially overlap, and the adjacent straightening wheels transfer the garlic seedlings grabbed by the hook grooves through the overlapping positions of the hook groove motion paths, the straightening wheels at the front end can penetrate into the planting soil layer to grab the fallen garlic seedlings, and the garlic seedlings are gradually straightened by transferring them between different straightening wheels, thereby meeting the demand for straightening the garlic seedlings for easy harvesting, and by designing the connection of the straightening wheels, the garlic seedlings are avoided from falling during the transfer process, the continuity of the movement of the garlic seedlings is guaranteed, the missed harvest rate is reduced, and the impact on subsequent planting is reduced.

[0023] The hook groove of the straightening wheel at the front end of the straightening section is extended out of the conveying channel and into the soil layer, and the hook groove is used to directly grab the garlic seedlings from the soil layer, thereby expanding the grabbing range. Garlic plants that have fallen on the ground and have deep roots and are difficult to grab by conventional methods can be grabbed, thereby improving the grabbing ability for special fallen garlic, further reducing the missed harvest rate, increasing the amount of harvested garlic, and ensuring the yield.

[0024] The hook grooves of the three straightening wheels are connected in sequence to form a coherent grasping and transfer path. After the first-level straightening wheel grabs the garlic seedlings, the garlic seedlings are stably transferred to the second-level straightening wheel through the hook groove connection, and then transferred from the second-level straightening wheel to the third-level straightening wheel, ensuring that the garlic seedlings transition smoothly between different straightening wheels, improving the stability and continuity of the garlic seedlings during the straightening process, reducing the drop of garlic seedlings due to improper transfer, reducing the risk of missed harvests, and improving harvesting efficiency.

[0025] Adjacent straightening wheels are staggered in the direction of the rotating axis, so that the grasping and working areas of each straightening wheel are different. The garlic sprouts can be grasped from different angles and positions, avoiding grasping conflicts caused by the overlap of the straightening wheel positions, and the garlic sprouts can be straightened more comprehensively. The working mode of the straightening wheels is optimized, the efficiency of grasping and straightening garlic sprouts is improved, the smooth harvesting process is ensured, and the situation of missed harvest is reduced.

[0026] The digging shovel is responsible for digging deep into the soil to dig the garlic roots, and the digging channel provides a transportation space for the excavated garlic. The digging section is used to cut off the connection between the garlic roots and the soil, and the clamping section cooperates with the auger to clamp and transport the excavated garlic plants, so that the garlic can be smoothly separated from the soil and enter the subsequent processing process, realizing the integrated operation of garlic from digging to clamping and transportation, improving the integrity and efficiency of garlic harvesting, and reducing garlic damage and missed harvesting caused by improper digging and transportation.

DETAILED DESCRIPTION

[0034] Example 1

[0035] In a typical embodiment of the present invention, Figure 1-Figure 5 As shown, a garlic lodging and straightening synchronous harvesting front device is provided.

[0036] The existing garlic digging and paving machine's grass-separating and guiding device can only guide the crooked garlic seedlings, but cannot effectively guide the garlic that has fallen on the ground, resulting in a high missed harvest rate, reduced yield and affecting the planting of the next crop. Based on this, this embodiment provides a garlic lodging straightening and synchronous harvesting pre-device, which aims to solve the missed harvest problem caused by the difficulty in guiding the lodging garlic, reduce the missed harvest rate, ensure the garlic yield, and reduce the impact on subsequent planting.

[0037] Specifically, Figure 1-Figure 5 As shown, the pre-installed device for straightening and synchronous harvesting of fallen garlic mainly includes a straightening shovel 2, a digging shovel 1 and a straightening wheel. At least two straightening shovels 2 are arranged in parallel, and a conveying channel is formed between adjacent straightening shovels 2. The seedling part of the garlic seedling moves along the conveying channel under the straightening constraint of the conveying channel. The digging shovel 1 is located below the straightening shovel 2. At least two digging shovels 1 are arranged in parallel, and a digging channel is formed between adjacent digging shovels 1. The digging channel can support the garlic head part of the garlic seedling and move under the support and limit of the digging channel. The fallen garlic seedlings 3 are straightened and moved under the joint action of the digging shovel 1 and the straightening shovel 2 until they enter the subsequent processing flow of the harvester.

[0038] In order to solve the problem that the fallen garlic is difficult to enter the subsequent clamping working end, at least two parallel straightening shovels 2 are provided, and a conveying channel is formed between adjacent straightening shovels 2. The straightening shovels 2 provide structural support for the entire device, and the conveying channel is a moving planning route for the garlic seedlings, allowing the garlic seedlings to move along the set direction, which is convenient for subsequent operations such as straightening and conveying the garlic seedlings.

[0039] The straightening shovel 2 provides a basic path for the subsequent treatment of fallen garlic, guiding the garlic plants to move to the subsequent treatment components, increasing the possibility of garlic entering the subsequent harvesting process and reducing the probability of missed harvesting.

[0040] In other optional embodiments, multiple groups of straightening shovels 2 can be provided, with two in each group, and a conveying channel is formed between the two straightening shovels 2 in the same group. Multiple groups of straightening shovels 2 are installed at intervals at the front end of the harvester to achieve the required straightening and guiding work.

[0041] Specifically, in order to carry out the straightening and separation operations of the fallen garlic in an orderly manner, improve the harvesting efficiency, and avoid the omission or damage of garlic due to chaotic operation, in this embodiment, the conveying channel is described in sections, and the conveying channel is divided into a straightening section and a separation section along the moving direction of the garlic seedlings in the conveying channel. The straightening section straightens the fallen garlic seedlings, and the separation section is responsible for receiving the straightened garlic seedlings and performing subsequent separation and other operations. The processing functions of different stages are clarified to facilitate a clear description of the structure. The process of garlic harvesting is optimized to ensure that the straightening and separation operations do not interfere with each other, improve the harvesting efficiency, ensure the integrity of the harvest, and reduce the omission rate.

[0042] In order to solve the problem that fallen garlic is difficult to be effectively grasped and straightened, at least two straightening wheels are staggered on the straightening shovels 2 on both sides of the straightening section, and the straightening wheels are rotatably installed on the straightening shovels 2, and hook grooves 13 for grasping garlic seedlings are provided on the straightening wheels. The rotating straightening wheels grasp the garlic seedlings that have fallen on the ground through the hook grooves 13. The staggered straightening wheels can reduce the interference caused by the straightening wheels on the same straightening shovel 2 being arranged too close, and at the same time, it is also beneficial to the transfer process of the garlic seedlings. The success rate of grasping the fallen garlic seedlings 3 is improved, so that more fallen garlic can be straightened and enter the subsequent harvesting process, reducing the missed harvest caused by failure to grasp, and ensuring the garlic harvest yield.

[0043] It should be pointed out that in order to realize the transfer of garlic sprouts in the straightening section, the reciprocating swing motion paths of adjacent straightening wheels partially overlap, and the garlic sprouts caught by the hook groove 13 are transferred between adjacent straightening wheels through the overlapping position of the hook groove 13 motion path. This design makes the garlic sprouts more stable when transferred between different straightening wheels, avoids falling during the transfer process, and ensures the continuity of the movement of the garlic sprouts. It ensures that the garlic sprouts will not fall due to transfer problems during the straightening process, further reduces the missed harvest rate, and improves the reliability of harvesting.

[0044] like Figure 3 and Figure 4 As shown, the hook groove 13 of the straightening wheel at the end of the straightening section is connected with the separation section, so that the straightened garlic seedlings can smoothly transition from the straightening section to the separation section, realizing seamless connection from the straightening to the subsequent processing links. This ensures the smooth progress of the entire harvesting process, allowing the garlic to be harvested continuously, helping to reduce the missed harvest rate and improve the harvesting efficiency and yield.

[0045] like Figure 1 and Figure 2As shown, for the problem that garlic that has fallen seriously and is close to the ground is difficult to grab by conventional methods, in this embodiment, along the direction from the straightening section to the separation section, the hook groove 13 of the straightening wheel at the head end of the straightening section can be extended to the outside of the conveying channel, so that the hook groove 13 can be inserted into the planting soil layer to grab the garlic seedlings; the hook groove 13 of the straightening wheel at the head end of the straightening section is extended out of the conveying channel and into the soil layer, and the garlic seedlings are directly grabbed from the soil layer using the hook groove 13, which expands the grabbing range and can grab those garlic plants that have fallen on the ground and have deep roots and are difficult to grab by conventional methods. The ability to grab special lodging garlic is improved, the missed harvest rate is further reduced, the amount of harvested garlic is increased, and the yield is guaranteed.

[0046] like Figure 1 As shown, there are three straightening wheels, namely, a first-stage straightening wheel 4, a second-stage straightening wheel 5 and a third-stage straightening wheel 6. The hook grooves 13 on the first-stage straightening wheel 4, the second-stage straightening wheel 5 and the third-stage straightening wheel 6 are connected in sequence to enhance the stability of grasping and transferring the garlic sprouts, prevent the garlic sprouts from falling or deviating during the straightening process, and ensure the continuity of the harvest.

[0047] The hook grooves 13 of the three straightening wheels are connected in sequence to form a coherent grasping and transfer path. After the first straightening wheel 4 grasps the garlic sprouts, the garlic sprouts are stably transferred to the second straightening wheel 5 through the hook groove 13, and then transferred from the second straightening wheel 5 to the third straightening wheel 6, ensuring that the garlic sprouts are smoothly transferred between different straightening wheels.

[0048] It can be understood that the present embodiment is described by taking the arrangement of three straightening wheels as an example. In other optional implementations, two, four, or five straightening wheels can be arranged so that they can be connected through the hook groove 13 to transfer the garlic sprouts, so that the garlic sprouts are transferred along the straightening section toward the separation section, thereby improving the stability and continuity of the garlic sprouts during the straightening process, reducing the falling of garlic sprouts due to improper transfer, reducing the risk of missed harvests, and improving harvesting efficiency.

[0049] In order to prevent the adjacent straightening wheels from interfering with each other when grabbing and transferring the garlic sprouts, and at the same time improve the grabbing and straightening effect of different parts of the garlic sprouts, such as Figure 2 As shown, along the direction from the straightening section to the separation section, adjacent straightening wheels are staggered in the direction of their rotation axes, so that the grasping surface positions of each straightening wheel are staggered, and the garlic sprouts can be grasped from different angles and positions, avoiding grasping conflicts caused by overlapping straightening wheel positions, and the garlic sprouts can be straightened more comprehensively.

[0050] The working mode of the straightening wheel has been optimized, which has improved the efficiency of grabbing and straightening the garlic sprouts, ensured the smooth progress of the harvesting process, and reduced missed harvests.

[0051] The straightening shovel 2 is mainly used to grab and straighten the upper part of the garlic seedlings. As the garlic seedlings are straightened, the garlic heads at the bottom of the garlic seedlings need to be dug and transported. Based on this requirement, a digging shovel 1 is set. Figure 1 As shown, at least two digging shovels 1 are arranged in parallel, and a digging channel is formed between adjacent digging shovels 1. Along the conveying direction of the garlic seedlings carried by the digging shovels 1, the digging channel is divided into a digging section and a clamping section. The digging shovels 1 on both sides of the clamping section are provided with augers; the digging of the garlic roots and the clamping and conveying of the garlic plants after digging are realized, thereby solving the problem that the garlic cannot be completely harvested from the soil by just straightening.

[0052] The digging shovel 1 is responsible for digging the garlic roots deep into the soil, and the digging channel provides a conveying space for the excavated garlic. The digging section is used to cut off the connection between the garlic roots and the soil, and the clamping section cooperates with the auger to clamp and convey the excavated garlic plants, so that the garlic can be smoothly separated from the soil and enter the subsequent processing process. The integrated operation of garlic from digging to clamping and conveying is realized, which improves the integrity and efficiency of garlic harvesting and reduces the damage and missed harvest of garlic caused by improper digging and conveying.

[0053] like Figure 2 As shown, the front end of the digging shovel 1 extends to below the straightening wheel at the end of the straightening section to receive the bottom of the garlic seedlings grabbed by the straightening wheel; ensuring that the straightened garlic seedlings can be smoothly transferred to the digging shovel 1 for digging, avoiding the garlic seedlings from falling or becoming disconnected during the conversion link, and ensuring the continuity of the harvesting process. The position design of the front end of the digging shovel 1 allows the bottom of the garlic seedlings grabbed by the straightening wheel to accurately fall on the digging shovel 1 when they reach the end, achieving seamless connection from straightening to digging, allowing the garlic seedlings to smoothly enter the digging process. The continuity of the harvesting process is improved, the missed harvests due to improper connection are reduced, and the integrity and efficiency of the garlic harvest are guaranteed.

[0054] The clamping section and the digging section are arranged tilted, and the tilt difference between the digging section and the clamping end relative to the horizontal plane optimizes the digging and clamping effects, making the garlic more in line with the mechanical principles during the digging and clamping process, thereby improving the smoothness of the harvest and the integrity of the garlic.

[0055] The inclined arrangement of the digging section and the clamping section helps the digging shovel 1 to cut into the soil more easily to dig the garlic roots. Different inclination angles are set to meet different mechanical requirements when digging and clamping garlic. The inclination of the digging section is conducive to breaking the soil for digging, and the inclination of the clamping section is convenient for clamping and transporting the excavated garlic; the efficiency of digging and clamping is improved, the damage to the garlic is reduced, the integrity of the garlic is ensured, the harvest quality is improved, and the missed harvest and breakage rate are reduced.

[0056] In the vertical direction, the conveying channel and the digging channel are distributed in the same plane, which simplifies the device structure and makes the transition of garlic sprouts in the process of conveying and digging smoother, avoiding the garlic from getting stuck or falling due to channel mismatch.

[0057] The conveying channel and the digging channel are coplanar in the vertical direction, ensuring that the transition of the garlic seedlings from the conveying channel to the digging channel is carried out in the same plane, reducing the obstacles caused by the height difference, and allowing the garlic to smoothly enter the digging stage from the straightening and conveying stage. The structure and work flow of the device are optimized, the smoothness of the harvest is improved, the risk of missed harvesting due to channel problems is reduced, and the harvesting efficiency is improved.

[0058] like Figure 1-Figure 5 As shown, the working process of the garlic lodging and straightening synchronous harvesting front device is described in detail.

[0059] The straightening shovel 2 is arranged at a certain downward tilt angle, and the lower end interferes with the planting soil at a certain distance (1-2cm depth). The first-level straightening wheel 4, the second-level straightening wheel 5, and the third-level straightening wheel 6 are installed on the two side rods of the straightening shovel 2 from bottom to top, and are staggered on both sides in the horizontal direction and do not interfere with each other in the vertical direction. The far end of the straightening piece is hook-shaped, and an arc-shaped hook groove 13 is provided on the inner edge. The rotation radius of the first-level straightening wheel 4 is flush with the end of the straightening shovel 2. During operation, it will penetrate into the planting soil layer for a certain distance (1-2cm depth) to ensure that the fallen garlic seedlings 3 are hooked up. The fallen garlic seedlings 3 after being hooked up are transported as the first-level straightening wheel 4 rotates (rotation angular velocity W1, reciprocating rotation), and the transportation stroke angle is φ1. At this time, it enters the straightening distance 8 of the excavating shovel 1, and the second-level straightening wheel 5 rotates at an angular velocity W2, and the rotation stroke angle is φ2, and reciprocates. When the first-level straightening wheel 4 and the second-level straightening wheel 5 rotate to the same direction of motion vector position, the unidirectional stroke of the first-level straightening wheel 4 ends at this time, and the fallen garlic seedlings 3 are separated from the first-level straightening wheel 4, and continue to drive the fallen garlic seedlings 3 to rotate and transport forward at an angular velocity W2 with the second-level straightening wheel 5. The tertiary straightening wheel 6 rotates at an angular velocity W3, and the rotation stroke angle is φ3, and reciprocates. When the second-level straightening wheel 5 and When the tertiary straightening wheel 6 rotates to the position of the same direction of motion vector, the unidirectional stroke of the secondary straightening wheel 5 ends at this time, and the fallen garlic seedlings 3 are separated from the secondary straightening wheel 5, and continue to drive the fallen garlic seedlings 3 to rotate and transport forward with the tertiary straightening wheel 6 at an angular velocity W2. When the tertiary straightening wheel 6 turns to a motion direction parallel to the straightening shovel 2, that is, at this time, the fallen garlic seedlings 3 are transported to the position of the digging shovel 1 and enter the digging distance 9D2. The digging shovel 1 is directly below the straightening shovel 2. The digging shovel 1 is divided into a digging section and a clamping section. The clamping section has a transport dragon. The digging shovel 1 digs the garlic seedlings out and clamps and transports the garlic seedlings through the transport dragon. At this time, the straightening section plays an auxiliary supporting role for the fallen garlic seedlings 3, and the clamping section of the digging shovel 1 continues to transport the upright garlic seedlings 12 and enters the clamping distance 10D3. The corresponding straightening shovel 2 is a separation section. The spacing between the digging shovels 1 in the separation section becomes larger and forms a certain external angle. At this time, the upright garlic seedlings 12 are completely separated from the digging shovel 1.

[0060] It should be noted that during the transportation of the fallen garlic seedlings 3 by the first-stage straightening wheel 4, the second-stage straightening wheel 5, and the third-stage straightening wheel 6, they are all in the straightening stage, and the fallen garlic seedlings 3 need to be straightened and fixed in position and moved upward in sequence, and the fallen garlic seedlings 3 are gradually straightened to become upright garlic seedlings 12. The upright garlic seedlings 12 gradually complete the transition from the straightening shovel 2 to the digging shovel 1 in the digging stage and the clamping stage, and are finally transported by the clamping stage of the digging shovel 1.

[0061] It should be noted that the single-column operation time of the harvesting equipment is t=D / V, where D is the plant spacing and V is the harvesting rate. The one-way time of the first-stage straightening wheel 4, the second-stage straightening wheel 5, and the third-stage straightening wheel 6 are t1, t2, and t3 respectively. When the first-stage straightening wheel 4 and the second-stage straightening wheel 5 rotate in the same direction, the transportation of the fallen garlic seedlings 3 is replaced. The rotation time of the first-stage straightening wheel 4 from the start of operation to the operation of the fallen garlic seedlings 3 in the hook is t 11 At this time, the first-level straightening wheel 4 starts to rotate from the hook to the lodging garlic seedling 3, and the rotation time is t 12 , t1=t 11 +t 12 = t / 2, to ensure that the fallen garlic seedlings 3 are not left out, the rotation time of the secondary straightening wheel 5 is t 21 , when installing the speed regulator, ensure that t 12 =t 21 , to ensure that the fallen garlic seedlings 3 in the hook are transferred to the secondary straightening wheel 5. Similarly, when the rotation vector direction of the secondary straightening wheel 5 is the same as that of the tertiary straightening wheel 6, the rotation time of the secondary straightening wheel 5 from the fallen garlic seedlings 3 in the hook is t 22 , the rotation time of the three-stage straightening wheel 6 is t 31 , when installing the speed regulator, ensure that t 22 =t 31 , to ensure that the fallen garlic seedlings 3 in the hook are transferred to the three-level straightening wheel 6, and the three-level straightening wheel 6 drives the fallen garlic seedlings 3 to rotate to the clamping and transportation direction, and the rotation time is t 32 At this time, the one-way travel of the three-stage straightening wheel 6 ends, and the clamping force of the clamping section of the excavator shovel 1 is connected.

[0067] The straightening wheel at the next level swings, and when the two adjacent straightening wheels swing to overlap the hook groove 13, the straightening wheel at the upper level swings in the opposite direction, and the straightening wheel at the lower level continues to swing, so that the garlic seedlings are transferred between the straightening wheels at different levels; the straightening wheels swing in sequence to transfer the garlic seedlings;

[0068] Until it is transferred to the straightening wheel at the end of the straightening section, the garlic sprouts caught by the hook groove 13 of the straightening wheel are transferred to the separation section;
