Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of potato harvesting devices, specifically to an integrated machine for simultaneous harvesting of sweet potato vines and tubers. Background Technology

[0002] Tuber crops, also known as root and tuber crops, mainly include sweet potatoes, potatoes, yams, and taro. The product organs of these crops are tubers and rhizomes, which grow in the soil and have two physiological stages: the early growth stage and the tuber (rhizome) enlargement stage.

[0003] The original harvesting method involved manually turning the fruit out of the soil with tools such as shovels or plows, then separating the fruit from the vines and leaves, and finally collecting the fruit. This process was time-consuming, labor-intensive, and inefficient. Later, people developed harvesting machines, which could be driven by a machine head (such as a tractor) to pass through the planting area and turn the fruit of tuber crops directly out of the soil, thus reducing the amount and intensity of manual labor to some extent.

[0004] Current harvesters primarily focus on collecting the fruit. After the fruit is shoveled from the soil, it is separated from the vines and leaves, and then the vines and fruit are placed separately. However, due to the characteristic of tuber crops' vines being "long," meaning they grow quite long during the crop's growth cycle and often intertwine, the separated vines form long "vines." When processing the vines after fruit collection, the presence of these "vines" significantly increases the difficulty of handling them. Additional manpower and resources are needed to break and disperse the "vines" before collecting and transporting them outside the planting area. The entire process is cumbersome, time-consuming, and labor-intensive. Furthermore, the process of breaking and dispersing the "vines" generates many broken vine fragments scattered throughout the planting area, further increasing the workload of cleaning. Therefore, improvements and optimizations to the existing technology are necessary. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide an integrated machine for simultaneous harvesting of sweet potato vines and tubers, which solves the problems of difficult, time-consuming and labor-intensive handling of "vines" after the harvest of sweet potato fruits in related technologies.

[0006] According to one aspect, at least one embodiment of this disclosure provides an integrated machine for simultaneous harvesting of sweet potato vines and tubers, comprising:

[0007] The machine frame moves above the ridges where crops are planted;

[0008] The seedling picker is rotatably mounted relative to the frame. Viewed along the walking direction of the frame, the seedling picker is configured to be inserted into the seedling leaves above the ridge after rotation. The seedling picker is used to pick up the seedling leaves along the rotation direction of the seedling picker.

[0009] Several rotating seedling components are spaced apart and rotatably arranged relative to the frame, with a cutting space formed between any two adjacent rotating seedling components; viewed along the traveling direction of the frame, the rotating seedling components are located behind the seedling picking components, and the rotating seedling components are used to receive the seedling leaves picked up by the seedling picking components;

[0010] A cutter is mounted on the frame and is configured such that after the rotating seedling device rotates, the cutter passes through the cutting space and is used to cut the seedling leaves received by the rotating seedling device.

[0011] For example, in at least one embodiment of the sweet potato vine and potato synchronous harvesting machine provided in this disclosure, the vine-picking component includes:

[0012] The straight rod segment and the inclined rod segment are connected to each other and are inclined to each other. When viewed from the center of the straight rod segment, the inclined rod segment is inclined in the direction of rotation of the seedling picker.

[0013] For example, in at least one embodiment of the sweet potato vine and potato synchronous harvesting machine provided in this disclosure, the sweet potato vine and potato synchronous harvesting machine further includes:

[0014] Several spaced seedling transport components are arranged in a cyclic transmission relative to the frame. When viewed along the walking direction of the frame, the seedling transport components are located behind the seedling transfer components. The seedling transport components are used to receive and transport the seedling leaves after they have been cut by the cutter.

[0015] For example, in at least one embodiment of the sweet potato vine and potato synchronous harvesting machine provided in this disclosure, the sweet potato vine and potato synchronous harvesting machine further includes:

[0016] There are at least two seedling transport shafts, which are rotatably mounted on the frame;

[0017] A seedling transport transmission unit is disposed on the seedling transport shaft, and the seedling transport components are distributed at intervals on the seedling transport transmission unit. When the seedling transport transmission unit is configured as the seedling transport shaft, the seedling transport transmission unit is used to drive the seedling transport components to circulate relative to the frame.

[0018] All the seedling transport axes are located in the same plane, which is defined as the transport surface. When viewed along the walking direction of the frame, the extension direction of the transport surface points diagonally upward and backward, and the transport surface is set at an inclined angle with the ridge.

[0019] For example, in at least one embodiment of the sweet potato vine and potato synchronous harvesting machine provided in this disclosure, the sweet potato vine and potato synchronous harvesting machine further includes:

[0020] The seedling separating component is mounted on the frame, and the seedling transport component is located below the seedling transport transmission unit. The seedling separating component has a seedling shovel head configured to shovel the seedling leaves transported by the seedling transport component during its cyclic transmission.

[0021] For example, in the integrated sweet potato vine and potato harvesting machine provided in at least one embodiment of this disclosure, the vine transport transmission unit includes:

[0022] A seedling conveying sprocket is mounted on the seedling conveying shaft;

[0023] A seedling transport chain is wound around the seedling transport sprocket, and the seedling transport component is disposed on the seedling transport chain.

[0024] For example, in at least one embodiment of the sweet potato vine and potato synchronous harvesting machine provided in this disclosure, the sweet potato vine and potato synchronous harvesting machine further includes:

[0025] A loading platform is mounted on the frame and located below the seedling transport unit. The loading platform is used to place the seedling collecting device for collecting the seedling leaves.

[0026] For example, in at least one embodiment of the sweet potato vine and potato synchronous harvesting integrated machine provided in this disclosure, the sweet potato vine and potato synchronous harvesting integrated machine further includes a power transmission unit, the power transmission unit including:

[0027] The drive shaft is rotatably mounted on the frame;

[0028] A seedling-picking shaft is rotatably mounted on the machine frame, and the seedling-picking component is mounted on the seedling-picking shaft;

[0029] A seedling rotating shaft is rotatably mounted on the machine frame, and the seedling rotating component is mounted on the seedling rotating shaft;

[0030] A first transmission belt is wound around the drive shaft, the seedling picking shaft, and the seedling rotating shaft. The first transmission belt is used to realize the transmission connection between the drive shaft, the seedling picking shaft, and the seedling rotating shaft.

[0031] A second transmission belt is wound around the rotating shaft and the transport shaft, and the second transmission belt is used to realize the transmission connection between the rotating shaft and the transport shaft.

[0032] For example, in at least one embodiment of the sweet potato vine and potato synchronous harvesting machine provided in this disclosure, the sweet potato vine and potato synchronous harvesting machine further includes:

[0033] The harvesting component, mounted on the frame, is used to dig the crop out of the ridge under the drive of the frame; viewed along the traveling direction of the frame, the harvesting component is located diagonally below and behind the rice-transferring component;

[0034] The soil dividing component has two sets, which are located on the left and right sides of the excavation component. Each set of soil dividing components contains several soil dividing components, and the several soil dividing components in each set are distributed at intervals along the walking direction of the frame.

[0035] For example, in the integrated harvester for simultaneous harvesting of sweet potato vines and tubers provided in at least one embodiment of this disclosure, the harvesting component has a plurality of spaced filter rods, and there is a filter gap between any two adjacent filter rods for filtering the crop.

[0036] The beneficial effects of the embodiments disclosed herein are as follows:

[0037] In this disclosure, when the integrated machine is in use, the frame is connected to an external power source (such as a tractor) in the prior art, and the power source moves the frame to the beginning end of the ridge. The seedling picker is in the shape of a long rod. As the frame moves, the seedling picker is inserted into the gap between the seedling leaves. An external force is applied to drive the seedling picker to rotate. The force generated by the rotation of the seedling picker lifts the seedling leaves upward, and the seedling leaves are pulled off the crop, so that the seedling leaves are separated from the crop. After being separated from the crop, the seedling leaves are flung diagonally upwards and backwards by the lifting mechanism. The flung leaves land on the rotating mechanism, spreading out within the cutting space. An external force drives the rotating mechanism to rotate, causing the leaves to gradually approach the cutter. Through the interlacing of the rotating mechanism and the cutter, the cutter and the cutting space move closer together, eventually the cutter cutting through the cutting space and severing the leaves. This rapid separation of the seedling leaves from the crop avoids the formation of "vines" as described in the background art, reducing subsequent processing steps, improving efficiency, reducing difficulty, and decreasing workload. Simultaneously, the centrifugal force generated by the rotating mechanism flung the severed leaves backwards. This completes the separation of the seedling leaves from the crop and the severing of the leaves. Attached Figure Description

[0046] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0047] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0048] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0049] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0050] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0051] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0052] like Figures 1-6 As shown, it illustrates a sweet potato vine and potato synchronous harvesting integrated machine in one embodiment of the present disclosure.

[0053] In some examples, the integrated sweet potato vine and tuber harvester includes a frame 1, a vine-picking component 2, a vine-rotating component 3, and a cutter 4. The frame 1 travels above the ridges where the crop is planted. The vine-picking component 2 is rotatably positioned relative to the frame 1. Viewed along the travel direction of the frame 1, the vine-picking component 2 is configured to be inserted into the vine leaves above the ridges after rotation, and the vine-picking component 2 is used to pick up the vine leaves along the rotation direction of the vine-picking component 2. Several vine-rotating components 3 are spaced apart and rotatably positioned relative to the frame 1, and a cutting space is formed between any two adjacent vine-rotating components 3. Viewed along the travel direction of the frame 1, the vine-rotating component 3 is located behind the vine-picking component 2, and the vine-rotating component 3 is used to receive the vine leaves picked up by the vine-picking component 2. The cutter 4 is mounted on the frame 1, and the cutter 4 is configured to pass through the cutting space after the vine-rotating component 3 rotates and is used to cut the vine leaves received by the vine-rotating component 3.

[0054] For example, such as Figures 1-4 As shown, in use, the frame 1 is connected to an external power source (such as a tractor) in the existing technology, and the frame 1 is moved to the beginning end of the ridge with the help of the power source; the seedling picker 2 is in the shape of a long rod. As the frame 1 moves, the seedling picker 2 is inserted into the gap between the seedling leaves. An external force is applied to drive the seedling picker 2 to rotate. The force generated by the rotation of the seedling picker 2 lifts the seedling leaves upward, and the seedling leaves are pulled off the crop, so that the seedling leaves are separated from the crop. After being separated from the crop, the seedling leaves are flung diagonally upwards and backwards in the direction of rotation of the seedling picker 2. The leaves fall onto the rotating seedling device 3, where they are distributed within the cutting space. An external force drives the rotating seedling device 3 to rotate, causing the leaves to gradually approach the cutter 4. Through the interlacing of the rotating seedling device 3 and the cutter 4, the cutter 4 approaches the cutting space, eventually cutting through the space and severing the leaves. This rapid separation of the seedling leaves from the crop avoids the formation of the "vines" described in the background art, reduces subsequent processing steps, improves efficiency, reduces difficulty, and decreases workload. Simultaneously, the centrifugal force generated by the rotation of the rotating seedling device 3 flings the severed leaves backwards. This completes the separation of the seedling leaves from the crop and the severing of the leaves.

[0055] In some examples, the seedling picker 2 is further refined. The seedling picker 2 includes a straight rod segment and an inclined rod segment connected to each other. The straight rod segment and the inclined rod segment are inclined together. When viewed along the center of the straight rod segment, the inclined rod segment is inclined in the direction of rotation of the seedling picker 2.

[0056] For example, such as Figures 1-4 As shown, as the frame 1 moves, the inclined rod section is first inserted into the gap between the seedlings and leaves, and an external force is applied to drive the seedling picking component 2 to rotate. With the help of the force generated by the rotation of the seedling picking component 2 and the position design of the inclined rod section, it is easy to pick up the seedlings and leaves and swing them backward, which improves the separation effect of the seedlings and leaves from the crop. At the same time, it can prevent the seedlings and leaves from separating from the seedling picking component 2, which helps with the processing of the seedlings and leaves.

[0057] In some examples, the integrated machine for simultaneous harvesting of sweet potato vines and tubers has been optimized by adding several spaced-out seedling transport components 5. The seedling transport components 5 are arranged in a cyclic transmission relative to the frame 1. When viewed along the walking direction of the frame 1, the seedling transport components 5 are located behind the seedling transfer components 3. The seedling transport components 5 are used to receive and transport the seedlings and leaves cut by the cutter 4.

[0058] For example, such as Figures 1-4As shown, the seedling transport component 5 is a long rod-shaped part with an L-shaped cross-section. A transport gap is formed between any two adjacent seedling transport components 5. Seedling leaves thrown out by the rotating component 3 fall onto the seedling transport component 5, with the cut ends of the leaves inserted into the transport gap, thus hanging on the seedling transport component 5. Seedling leaves cut by the cutter 4, under the swinging action of the rotating component 3, fall onto the additional seedling transport component 5 for transport. This facilitates the collection of seedling leaves and enables continuous operation of separating, cutting, and transporting seedling leaves from the crop. This improves operational efficiency, avoids multiple separate processing of seedling leaves, simplifies the seedling leaf processing process, and enhances seedling leaf processing efficiency. The L-shape of the seedling transport component 5 allows for the conveying of cut seedling leaves, improving the efficiency of seedling leaf transport and preventing the seedling transport component 5 from failing to transport the leaves in time, causing seedling leaves to accumulate between the rotating component 3 and the seedling transport component 5, affecting seedling leaf processing and the operation of the integrated sweet potato vine and tuber harvesting machine.

[0059] In some examples, the structure of the integrated sweet potato vine and tuber harvester is refined by adding a vine-transporting shaft 11 and a vine-transporting transmission unit 13. There are at least two vine-transporting shafts 11, which are rotatably mounted on the frame 1. The vine-transporting transmission unit 13 is mounted on the vine-transporting shaft 11, and the vine-transporting components 5 are distributed at intervals on the vine-transporting transmission unit 13. When the vine-transporting transmission unit 13 is configured as a vine-transporting shaft 11, it is used to drive the vine-transporting components 5 to circulate relative to the frame 1. All vine-transporting shafts 11 are located in the same plane, which is defined as the transport surface. When viewed along the walking direction of the frame 1, the extension direction of the transport surface points diagonally upward and backward, and the transport surface is set at an inclined angle with the ridge.

[0060] For example, such as Figures 1-4 As shown, in this example, two seedling transport shafts 11 are selected to reduce the number of parts and simplify the equipment layout while ensuring normal operation. An external force is applied to drive the seedling transport shafts 11 to rotate, and the seedling transport unit 13 drives the seedling transport component 5 to circulate on the frame 1. The inclined transport surface allows the seedlings to be transported from a lower position to a higher position, facilitating collection. This prevents the seedlings cut by the cutter 4 from scattering directly into the planting area due to the swinging action of the rotating component 3, which would increase the difficulty of collection. Therefore, by using the inclined transport surface, the seedlings are transported diagonally upwards and backwards, raising their position and preventing cut seedlings from scattering onto the ridges, making it easier for farmers to collect the seedlings and reducing the subsequent collection workload.

[0061] In some examples, the structure of the integrated sweet potato vine and tuber harvester is refined by adding a vine-separating component 16, which is set on the frame 1. The vine-transporting component 5 is located below the vine-transporting transmission unit 13. The vine-separating component 16 has a shovel head, which is configured to shovel the vine leaves transported by the vine-transporting component 5 during its cyclic transmission.

[0062] For example, such as Figures 1-4 As shown, during use, the seedlings thrown out by the rotating seedling unit 3 fall onto the transporting seedling unit 5. With the cooperation of the transporting shaft 11 and the transporting transmission unit 13, the transporting seedling unit 5 carries the seedlings from a low position to a high position. At this time, the seedlings are attached to the transporting seedling unit 5. As the transporting seedling unit 5 moves, when it lifts the seedlings to the highest point, it gradually lowers from the highest point. During this process, the seedlings will fall off the transporting seedling unit 5. Even if some seedlings do not fall off and remain attached to the transporting seedling unit 5, the drooping end of the seedling attached to the transporting seedling unit 5 will fall on the side of the shovel head away from the transporting transmission unit 13. At this time, relative to the seedlings on the transporting transmission unit 13, the shovel head has a shoveling effect on the seedlings, which facilitates the separation of the seedlings from the transporting seedling unit 5. This ensures the transport effect of the transporting seedling unit 5 and prevents the seedlings from following the transporting seedling unit 5 to the side of the rotating seedling unit 3 again.

[0063] In some examples, the structure of the seedling transport transmission unit 13 is refined. The seedling transport transmission unit 13 includes a seedling transport sprocket 14 and a seedling transport chain 15. The seedling transport sprocket 14 is mounted on the seedling transport shaft 11. The seedling transport chain 15 is wound around the seedling transport sprocket 14, and the seedling transport component 5 is mounted on the seedling transport chain 15.

[0064] For example, such as Figures 1-4 As shown, the rotation of the seedling conveying shaft 11 drives the seedling conveying sprocket 14 to rotate, which in turn drives the seedling conveying chain 15 and the seedling conveying component 5 to move synchronously. This causes the seedling conveying component 5 to move along the cyclic trajectory of the seedling conveying chain 15, transporting the cut seedling leaves to the position to be processed. This ensures the continuity of the seedling leaf processing operation.

[0065] In some examples, a platform 17 is added to the integrated sweet potato vine and tuber harvester. The platform 17 is mounted on the frame 1 and located below the vine transport transmission unit 13. The platform 17 is used to place the vine-collecting components for collecting vine leaves. A bag-hanging rod 22 is installed on the frame 1 above the platform 17.

[0066] For example, such as Figures 1-5 As shown, when in use, the seedling collection piece carrying the seedling leaves can be a large packaging bag (such as a burlap sack, a large plastic bag, etc.); the seedling collection piece can be placed on the carrying platform 17, or it can be hung on the hanging bag rod 22; after being transported by the seedling transport piece 5, the seedling leaves are moved from one side of the seedling transport piece 3 to the highest point of the seedling transport transmission unit 13 by the seedling transport transmission unit 13 and then fall downwards. The seedling leaves will fall into the seedling collection piece, directly completing the seedling leaf collection operation. When the seedling collection piece is full of seedling leaves, the seedling collection piece can be replaced in time to ensure the continuous operation of seedling leaf processing and collection.

[0067] In addition, the platform 17 can also be swayed and mounted on the frame 1. The integrated sweet potato vine and potato harvester also includes a swing arm 23, a sliding member 24, and a connecting rod 25. The swing arm 23 is swayed and mounted on the frame 1, and the sliding member 24 is slidably mounted on the frame 1. When viewed along the traveling direction of the frame 1, the sliding member 24 is located in front of the platform 17. The two ends of the connecting rod 25 are respectively hinged to the swing arm 23 and the sliding member 24. Under the swinging operation of the swing arm 23, the sliding member 24 is engaged or disengaged above the platform 17. When the harvesting device is placed on the platform 17, the sliding member 24 is engaged above the platform 17. Looking along the travel direction of the frame 1, the swing origin of the platform 17 is located in front of its center of gravity. When the harvesting device is full of seedlings, the driving arm 23 rotates. The arm 23, through the connecting rod 25, drives the sliding member 24 to slide away from the platform 17 until the sliding member 24 separates from the platform 17. At this point, the rear half of the platform 17 swings downwards, and the harvesting device can slide diagonally backwards and downwards along the platform 17, finally landing on the raised bed. The swing of the platform 17 achieves automatic separation of the harvesting device from the platform 17. Then, an external force is applied to drive the platform 17 back to its initial position, awaiting the next operation.

[0068] In some examples, a power transmission unit 6 is added. The power transmission unit 6 includes a drive shaft 7, a seedling-picking shaft 8, a seedling-rotating shaft 9, a first transmission belt 10, and a second transmission belt 12. The drive shaft 7 is rotatably mounted on the frame 1. The seedling-picking shaft 8 is rotatably mounted on the frame 1, and the seedling-picking component 2 is mounted on the seedling-picking shaft 8. The seedling-rotating shaft 9 is rotatably mounted on the frame 1, and the seedling-rotating component 3 is mounted on the seedling-rotating shaft 9. The first transmission belt 10 is wound around the drive shaft 7, the seedling-picking shaft 8, and the seedling-rotating shaft 9, and the first transmission belt 10 is used to realize the transmission connection between the drive shaft 7, the seedling-picking shaft 8, and the seedling-rotating shaft 9. The second transmission belt 12 is wound around the seedling-rotating shaft 9 and the seedling-transporting shaft 11, and the second transmission belt 12 is used to realize the transmission connection between the seedling-rotating shaft 9 and the seedling-transporting shaft 11.

[0069] For example, such as Figures 1-4 As shown, during operation, a transmission, as used in the prior art, is installed on the frame 1. The transmission is connected to an external power source (such as a tractor). The transmission drives the drive shaft 7 to rotate. The drive shaft 7, through the first transmission belt 10, drives the seedling-picking shaft 8 and the seedling-turning shaft 9 to rotate simultaneously. The seedling-turning shaft 9, through the second transmission belt 12, drives the seedling-transporting shaft 11 to rotate synchronously. The power transmission unit 6 achieves centralized power transmission, ensuring the coordination and consistency of the rotation of the seedling-picking shaft 8, the seedling-turning shaft 9, and the seedling-transporting shaft 11. The first transmission belt 10 and the second transmission belt 12 can be chains, as used in the prior art. The drive shaft 7, the seedling-picking shaft 8, the seedling-turning shaft 9, and the seedling-transporting shaft 11 are equipped with sprockets, as used in the prior art, corresponding to chains, to ensure the stability of power transmission.

[0070] In some examples, the integrated sweet potato vine and potato harvesting machine is further refined by adding a digging component 18 and a soil separating component 19. The digging component 18 is mounted on the frame 1 and is used to dig the crop out of the ridge under the drive of the frame 1. Viewed along the traveling direction of the frame 1, the digging component 18 is located diagonally below and behind the rotating vine component 3. The soil separating component 19 has two sets, located on the left and right sides of the digging component 18. Each set of soil separating components 19 contains several soil separating components 19, and these components are spaced apart along the traveling direction of the frame 1. The digging component 18 has several spaced-apart filter rods 20, with a filter gap 21 between any two adjacent filter rods 20 for filtering the crop. The ends of the filter rods 20 are higher than the digging component 18.

[0071] For example, such as Figures 1-6 As shown, during use, as the frame 1 moves, the front end of the digging component 18 is shoveled into the ridge. After shoveling into a certain depth, the digging component 18 moves horizontally with the frame 1. At this time, the front end of the digging component 18 is located below the crop. At the same time, the soil separating component 19 is also shoveled into the soil on both sides of the ridge.

[0072] With the help of the frame 1 moving, the soil separating component 19 shovels the soil on both sides of the ridge away from the ridge, and the harvesting component 18 shovels the soil and fruit in the middle of the ridge upwards. The crop fruit rolls or slides on the upper surface of the harvesting component 18. After the soil and fruit move to the filter rod 20, the soil falls down from the filter gap 21, and the crop fruit will be briefly retained on the filter rod 20. As the frame 1, the harvesting component 18 and the soil separating component 19 continue to move, the filtered crop fruit is left on the soil, which is convenient for subsequent fruit collection.

[0073] A recessed arc surface 26 can be optionally added to the middle position of the excavator 18. The recessed arc surface 26 facilitates the excavator 18 to be shoveled into the ridge, reducing the operating resistance of the ridge to the excavator 18.

[0074] At the end of the frame 1, the integrated sweet potato vine and potato harvester is also equipped with a wheel frame 27 and a walking wheel 28. The wheel frame 27 is slidably mounted on the frame 1, and the walking wheel 28 is rotated on the wheel frame 27.
