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] Currently available self-propelled garlic combine harvesters can simultaneously complete the tasks of separating garlic stalks, digging, clamping, and separating the heads and stalks. During the garlic harvesting process, factors such as harvesting speed, breakage rate, and missed harvest rate need to be considered. An appropriate harvesting speed ensures that the garlic is harvested during the optimal harvest period, minimizing the risk of damage from rain, pests, and diseases. Minimizing breakage during the harvesting process and keeping the garlic intact reduces the risk of pathogens and rot caused by breakage. Reducing missed harvest rates maximizes yield and minimizes the impact on the planting and growth of the next crop.

[0003] A Chinese patent (publication number CN 108200795 A, publication date June 26, 2018) discloses a garlic digging and stripping machine that can effectively dig garlic plants, clamp them, transport them, and lay them on one side of the machine. The vibration digging resistance is small, the penetration effect is good, and the garlic plant clamping process is continuous and reliable. A separating and guiding device is provided at the front of the frame to straighten and guide the fallen garlic vines. This device separates and guides the garlic to be harvested in front of the frame, and can gather garlic vines that deviate from the planting ridge so that they can contact the clamping device. However, this device can only guide tilted garlic vines. For garlic that has fallen due to environmental factors such as weather, the separating and guiding device cannot effectively guide the fallen garlic that is close to the ground, making it difficult for the garlic to enter the subsequent clamping working end, resulting in missed harvests. This increases the missed harvest rate during garlic harvesting and makes it difficult to solve the problem of reduced yield caused by the high missed harvest rate and the impact on the next crop planting season. Summary of the Invention

[0004] The purpose of the present invention is to address the defects of the existing technology and provide a pre-positioned device and a harvesting method for synchronously harvesting fallen garlic by straightening it. Through a series of structural designs, the device can straighten and transport fallen garlic 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 device for synchronously harvesting garlic by straightening it from a fallen position, which adopts the following scheme:

[0006] It includes 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 staggered 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 at the head end of the straightening section can be extended out of the conveying channel, so that the hook groove can be inserted into the planting soil layer to grab the garlic sprouts.

[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, and a digging channel is formed between adjacent digging shovels. Along the transportation direction of the garlic sprouts carried by the digging shovel, the digging channel is divided into a digging section and a clamping section. The digging shovels on both sides of the clamping section are provided with augers.

[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] A second object of the present invention is to provide a harvesting method for garlic with a 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. 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, thus realizing the transfer of garlic sprouts between the straightening wheels at different levels. The straightening wheels swing in sequence to transfer the garlic sprouts.

[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] It enters the subsequent process of the harvesting equipment through the separation section.

[0020] Furthermore, the straightening wheel swings back and forth, grabbing the garlic sprouts distributed on the garlic sprout planting ridges one by one and transporting them to the separation section.

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

[0022] The 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. In order to solve 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 set to provide structural support and a conveying channel for the entire device. The conveying channel is a planned movement 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 of the garlic seedlings; at least two straightening wheels are staggered on the straightening shovels on both sides of the straightening section, and the reciprocating swinging motion paths of adjacent straightening wheels partially overlap, and the garlic seedlings caught by the hook grooves are transferred between the adjacent straightening wheels through the overlapping position of the hook groove motion paths. The straightening wheel 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, meeting the need of straightening the garlic seedlings for easy harvesting. 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. The hook groove is used to directly grab the garlic sprouts from the soil layer, which expands the grabbing range. It can grab those garlic plants that have fallen on the ground and have deep roots and are difficult to grab by conventional methods. It improves the grabbing ability of special fallen garlic, further reduces the missed harvest rate, increases the amount of harvested garlic, and ensures the yield.

[0024] The hook grooves of the three straightening wheels connect sequentially, forming a coherent grasping and transfer path. After the first straightening wheel grabs the garlic sprout, the hook groove connects and stably transfers the garlic sprout to the second straightening wheel, which then transfers it to the third straightening wheel. This ensures a smooth transition of the garlic sprouts between the different straightening wheels, improves the stability and consistency of the garlic sprouts during the straightening process, reduces the risk of garlic sprouts falling due to improper transfer, and improves 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. Garlic sprouts can be grasped from different angles and positions, avoiding grasping conflicts caused by overlapping straightening wheel positions, and can straighten garlic sprouts more comprehensively. The working mode of the straightening wheels is optimized, the efficiency of grasping and straightening garlic sprouts is improved, and the smooth harvesting process is ensured, reducing missed harvests.

[0026] The excavating shovel digs deep into the soil to reach the garlic roots, creating a channel for the excavated garlic to be transported. The excavating section severs the connection between the garlic roots and the soil, while the gripping section, in conjunction with the auger, grips and transports the excavated garlic plants, allowing them to be smoothly separated from the soil and subsequently processed. This integrated operation, from excavation to gripping and transporting, improves the integrity and efficiency of the garlic harvest and reduces damage and missed harvests caused by improper excavation and transport.

[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 stripping machines' stalk separation and guidance devices can only guide tilted garlic stalks, but are unable to effectively guide garlic that has fallen flat on the ground. This results in a high rate of missed harvests, reduced yields, and impacts the next crop season. To address this issue, this embodiment provides a pre-harvesting device for straightening fallen garlic stalks. This device aims to address the missed harvests caused by the difficulty of guiding fallen garlic, reduce the missed harvest rate, ensure garlic yields, and minimize the impact on subsequent plantings.

[0037] Specifically, such as 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 straightening wheels. At least two straightening shovels 2 are provided in parallel, forming a conveying channel between adjacent straightening shovels 2. The seedling portion of the garlic sprout moves along this conveying channel under the straightening constraint of this conveying channel. The digging shovel 1 is located below the straightening shovel 2. At least two digging shovels 1 are provided in parallel, forming a digging channel between adjacent digging shovels 1. The digging channel can support the bulb portion of the garlic sprout. Under the support and limit of the digging channel, the fallen garlic sprout 3 is straightened and moved by the combined action of the digging shovel 1 and the straightening shovel 2 until it enters the subsequent processing flow of the harvester.

[0038] To address the issue of fallen garlic having difficulty reaching the subsequent clamping end, at least two parallel straightening shovels 2 are provided, with a conveying channel formed between adjacent straightening shovels 2. The straightening shovels 2 provide structural support for the entire device, and the conveying channel is a planned movement route for the garlic sprouts, allowing them to move in a set direction, facilitating subsequent operations such as straightening and conveying the garlic sprouts.

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

[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, to ensure orderly straightening and separation of fallen garlic, improve harvesting efficiency, and avoid missed harvests or damage due to chaotic operations, this embodiment divides the conveyor channel into a straightening section and a separation section along the direction of movement of the garlic sprouts within the conveyor channel. The straightening section straightens fallen garlic sprouts, while the separation section receives the straightened garlic sprouts and performs subsequent separation operations. The processing functions of the different stages are clearly defined, facilitating a clear structural description. This optimizes the garlic harvesting process, ensuring that the straightening and separation operations do not interfere with each other, improving harvesting efficiency, ensuring harvest integrity, and reducing missed harvests.

[0042] To address the difficulty in effectively grabbing and straightening fallen garlic, at least two straightening wheels are staggered on the straightening shovel 2 on either side of the straightening section. These wheels are rotatably mounted on the shovel 2 and are equipped with hook grooves 13 for grabbing the garlic sprouts. The rotating straightening wheels use the hook grooves 13 to grab the fallen garlic sprouts. The staggered arrangement of the straightening wheels reduces interference caused by the close proximity of straightening wheels on the same straightening shovel 2 and also facilitates the transfer of the garlic sprouts. This improves the success rate of grabbing fallen garlic sprouts 3, allowing more fallen garlic to be straightened and entered into the subsequent harvesting process, reducing missed harvests due to failure to grab them, and ensuring the garlic harvest yield.

[0043] It should be noted that to facilitate the transfer of garlic sprouts within the straightening section, the reciprocating motion paths of adjacent straightening wheels partially overlap, and the garlic sprouts captured by hook grooves 13 are transferred between adjacent straightening wheels at the overlapping locations of their motion paths. This design ensures smoother transfer of garlic sprouts between straightening wheels, preventing them from falling during transfer and ensuring continuous movement. This ensures that garlic sprouts do not fall during the straightening process due to transfer issues, further reducing missed harvests and improving harvest reliability.

[0044] like Figure 3 and Figure 4 As shown, the hook groove 13 of the straightening wheel at the end of the straightening section connects with the separation section, allowing the straightened garlic sprouts to smoothly transition from the straightening section to the separation section, achieving a seamless connection from straightening to subsequent processing. This ensures a smooth harvest process, allowing the garlic to be harvested and processed continuously, helping to reduce missed harvest rates and improve harvesting efficiency and yield.

[0045] like Figure 1 and Figure 2As shown, to address the problem of severely lodged garlic plants that are closely attached to the ground and difficult to grasp using conventional methods, this embodiment allows the hook groove 13 of the straightening wheel at the head of the straightening section to extend beyond the conveying channel along the direction from the straightening section to the separation section, allowing the hook groove 13 to penetrate into the planting soil layer to grasp the garlic sprouts. The hook groove 13 of the straightening wheel at the head of the straightening section extends beyond the conveying channel and into the soil layer, allowing the garlic sprouts to be grasped directly from the soil layer. This expands the grasping range and can capture garlic plants that have fallen to the ground and have deep roots, making them difficult to grasp using conventional methods. This improves the grasping ability of particularly lodged garlic, further reduces the missed harvest rate, increases the amount of harvested garlic, and ensures the yield.

[0046] like Figure 1 As shown, there are three straightening wheels, namely the first-stage straightening wheel 4, the second-stage straightening wheel 5 and the 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, forming a coherent grasping and transfer path. After the first straightening wheel 4 grabs the garlic sprout, it is connected through the hook groove 13 to stably transfer the garlic sprout to the second straightening wheel 5, and then from the second straightening wheel 5 to the third straightening wheel 6, ensuring a smooth transition of the garlic sprout between the different straightening wheels.

[0048] It can be understood that the present embodiment is described by arranging three straightening wheels as an example. In other optional embodiments, 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 to the separation section, thereby improving the stability and continuity of the garlic sprouts during the straightening process, reducing the drop 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 can straighten the garlic sprouts 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 demand, a digging shovel 1 is set. Figure 1 As shown, at least two digging shovels 1 are provided in parallel, and a digging channel is formed between adjacent digging shovels 1. Along the conveying direction of the garlic sprouts 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 garlic roots and the garlic heads are dug and the garlic plants are clamped and conveyed after digging, solving the problem that the garlic cannot be harvested intact from the soil by just straightening them.

[0052] The digging shovel 1 digs deep into the soil to excavate the garlic roots, creating a channel for the excavated garlic to be transported. The digging section severs the connection between the garlic roots and the soil, while the gripping section cooperates with the auger to grip and transport the excavated garlic plants, allowing them to be smoothly removed from the soil and into subsequent processing. This achieves an integrated operation from excavation to gripping and transporting, improving the integrity and efficiency of the garlic harvest and reducing damage and missed harvests caused by improper excavation and transport.

[0053] like Figure 2 As shown, the front end of the digging shovel 1 extends 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. This ensures that the straightened garlic sprouts can be smoothly transferred to the digging shovel 1 for digging, preventing the garlic sprouts from falling or becoming disconnected during the transition, and ensuring the continuity of the harvesting process. The front end of the digging shovel 1 is positioned so that the bottom end of the garlic sprouts grasped by the straightening wheel can accurately land on the digging shovel 1 when they reach the end, achieving a seamless connection from straightening to digging, allowing the garlic sprouts to smoothly enter the digging process. This improves the continuity of the harvesting process, reduces missed harvests due to improper connection, and ensures the integrity and efficiency of the garlic harvest.

[0054] The clamping section and the digging section are arranged at an angle, and the difference in the inclination of 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 harvesting and the integrity of the garlic.

[0055] The tilted arrangement of the digging and gripping sections helps the shovel 1 more easily penetrate the soil and excavate the garlic roots. Different tilt angles accommodate the varying mechanical requirements of digging and gripping the garlic. The tilt of the digging section facilitates breaking the soil, while the tilt of the gripping section facilitates gripping and transporting the excavated garlic. This improves digging and gripping efficiency, reduces damage to the garlic, ensures its integrity, improves harvest quality, and reduces missed harvests and breakage rates.

[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 conveying and digging process smoother, avoiding the garlic from getting stuck or falling due to channel mismatch.

[0057] The conveying channel and the digging channel are vertically coplanar, ensuring that the garlic sprouts transition from the conveying channel to the digging channel on the same plane. This reduces obstacles caused by height differences and allows the garlic to smoothly transition from the straightening conveying stage to the digging stage. This optimizes the device's structure and workflow, improves harvesting efficiency, reduces the risk of missed harvests due to channel problems, and enhances harvesting efficiency.

[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. They are staggered on both sides in the horizontal direction and do not interfere with each other in the vertical direction. The distal 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 (1-2 cm depth) to ensure that the fallen garlic seedlings 3 are hooked up. After being hooked up, the fallen garlic seedlings 3 are transported as the first-level straightening wheel 4 rotates (rotation angular velocity W1, reciprocating rotation). The transportation stroke angle is φ1, and at this time, it enters the straightening distance 8 of the excavating shovel 1. The second-level straightening wheel 5 rotates at an angular velocity W2, and the rotation stroke angle is φ2, and it rotates back and forth. When the first-level straightening wheel 4 and the second-level straightening wheel 5 rotate to the same direction of motion vector position, the one-way 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 third-level straightening wheel 6 rotates at an angular velocity W3, and the rotation stroke angle is φ3, and it rotates back and forth. When the second-level straightening wheel 5 and When the third-level straightening wheel 6 rotates to the position of the same direction of motion vector, the one-way stroke of the second-level straightening wheel 5 ends, and the fallen garlic seedlings 3 are separated from the second-level straightening wheel 5, and continue to drive the fallen garlic seedlings 3 to rotate and transport forward with the third-level straightening wheel 6 at an angular velocity W2. When the third-level 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 the 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 sprouts 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 section. The fallen garlic sprouts 3 that need to be straightened are fixed in position and moved upward in sequence. The fallen garlic sprouts 3 are gradually straightened and become upright garlic sprouts 12. The upright garlic sprouts 12 gradually complete the transition from the straightening shovel 2 to the digging shovel 1 in the digging section and the clamping section, and are finally transported by the clamping section 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 rotation vector directions of the first-stage straightening wheel 4 and the second-stage straightening wheel 5 are the same, 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 hook of the fallen garlic seedlings 3 is t 11 At this time, the first-level straightening wheel 4 starts to rotate from the hook to the 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 starting 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 stroke of the three-stage straightening wheel 6 ends, and the clamping force of the clamping section of the excavating shovel 1 is connected.

[0063] In another typical embodiment of the present invention, Figure 1-Figure 5 As shown, a harvesting method of garlic with a lodging and straightening synchronous harvesting front device is provided, using the garlic lodging and straightening synchronous harvesting front device as in Example 1.

[0065] Move to the garlic seedling planting ridge position and harvest along the planting ridge;

[0066] The straightening wheel at the front end of the straightening section swings, and after partially penetrating into the planting soil layer, the hook groove 13 is used to grab the fallen garlic seedlings. The fallen garlic seedlings 3 after being hooked rotate with the straightening wheel, so that the fallen garlic seedlings 3 enter the conveying channel;

[0067] The vertical wheel at the next level swings, and when the two adjacent vertical wheels swing to the point where the hook groove 13 overlaps, the vertical wheel at the upper level swings in the opposite direction, and the vertical wheel at the lower level continues to swing, thereby realizing the transfer of garlic sprouts between the vertical wheels at different levels; the vertical wheels swing in sequence to transfer the garlic sprouts;

[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;

[0069] It enters the subsequent process of the harvesting equipment through the separation section.

[0070] The straightening wheel swings back and forth, grabbing the garlic sprouts distributed on the garlic sprout planting ridges one by one and transporting them to the separation section.

The garlic lodging and straightening synchronous harvesting pre-device according to claim 1, characterized in that: The clamping section and the digging section are arranged obliquely, and the inclinations of the digging section and the clamping section relative to the horizontal plane are set differently.

5. The garlic lodging and straightening synchronous harvesting pre-device according to claim 4, characterized in that: In the vertical direction, the conveying channel and the excavation channel are distributed in the same plane.

6. A method for harvesting garlic using a pre-mounted device for synchronous harvesting by straightening and straightening the garlic after it has fallen down, comprising: include: Move to the garlic seedling planting ridge position and harvest along the planting ridge; 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; The straightening wheel at the next level swings. 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, thus realizing the transfer of garlic sprouts between the straightening wheels at different levels. The straightening wheels swing in sequence to transfer the garlic sprouts. 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; It enters the subsequent process of the harvesting equipment through the separation section.

7. The harvesting method of garlic with a pre-mounted device for synchronous harvesting by straightening and straightening the garlic according to claim 6, characterized in that: The straightening wheel swings back and forth to grab the garlic sprouts distributed on the garlic sprout planting ridges one by one and transport them to the separation section.
