DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 3As shown, the white radish combine harvester of this embodiment includes a traveling chassis 1, on which is mounted a frame 2. A subsoiling mechanism 3 for vibrating the soil to loosen it and a leaf-holding mechanism 4 for gathering the radish leaves are mounted at the front end of the frame 2. A primary clamping and conveying mechanism 5 is mounted behind the leaf-holding mechanism 4 for clamping, pulling up, and transporting the gathered radish leaves. A secondary clamping and conveying mechanism 6 is mounted below the primary clamping and conveying mechanism 5 for clamping and conveying the radish fruits conveyed by the primary clamping and conveying mechanism 5 and for synchronously conveying them with the primary clamping and conveying mechanism 5. A cutting mechanism 7 is also mounted on the traveling chassis 1 in a manner that allows for adjustment of the mounting height. During operation, the subsoiling mechanism 3 first loosens the soil to break the adhesion between the radish and the soil, ensuring that the radish is smoothly pulled up and achieving a low-loss harvest. The leaf-holding mechanism 4 holds up the radish tufts and leaves. As the walking chassis 1 moves forward, the radish tufts and leaves are at the entrance end of the first-level clamping and conveying mechanism 5 after they are separated from the leaf-holding mechanism 4. Then the first-level clamping and conveying mechanism 5 clamps and pulls up the gathered tufts and transports them. When they are transported to the radish fruit that is clamped by the second-level clamping and conveying mechanism 6, the cutting mechanism 7 cuts off the tufts and leaves, thereby separating the radish tufts and leaves from the fruit. After the tufts are cut, the radish fruit is separated from the second-level clamping and conveying mechanism 6 and collected under the action of gravity. After the tufts are separated from the first-level clamping and conveying mechanism 5, the radish tufts are thrown into the field. The deep loosening mechanism 3, the leaf-holding mechanism 4 and the first-level clamping and conveying mechanism 5 are installed on the walking chassis 1 in a manner that can adjust the installation height. The distance between the deep loosening mechanism 3, the leaf-holding mechanism 4 and the first-level clamping and conveying mechanism 5 and the ground can be changed to meet the needs of different operation scenarios, road transportation, obstacle climbing, etc., thereby improving the scene applicability and enhancing practicality. The white radish combine harvester is a multifunctional combined operation harvester that integrates deep loosening, tassel and leaf gathering, clamping and conveying, and cutting. It has the advantages of multifunctional combined operation, strong scene applicability and strong practicality.

[0025] In this embodiment, the chassis 1 is provided with a mounting base 11, which is mounted to the chassis 1 via a first height adjustment assembly for adjustable mounting height. Ground wheels 8 are mounted on the mounting base 11. The mounting base 11 is attached to the chassis 1 via the first height adjustment assembly, which adjusts the height of the mounting base 11 relative to the ground. Ground wheels 8 are rollingly mounted on the mounting base 11, moving up and down with the mounting base 11 to maintain balance of the entire structure.

[0026] In this embodiment, the first height adjustment assembly includes one or more connecting rods 80 and an adjusting cylinder 81. One end of the connecting rod 80 is hinged to the frame 2, and the other end of the connecting rod 80 is fixedly connected to the mounting base 11. One end of the adjusting cylinder 81 is hinged to the connecting rod 80, and the other end of the adjusting cylinder 81 is hinged to the frame 2. Under the telescopic adjustment action of the adjusting cylinder 81, the connecting rod 80 swings back and forth about the hinge point on the frame 2 as the axis, and the mounting base 11 fixedly connected to the connecting rod 80 can also swing back and forth with the connecting rod 80. The first height adjustment assembly adopts the form of an adjusting cylinder 81 plus a connecting rod 80, which has a simple structure, stable operation, reliable operation, and easy control. In other embodiments, a telescopic cylinder or other mechanical structure can also be used to achieve the up and down reciprocating swing of the connecting rod 80. In this embodiment, the mounting base 11 includes a plurality of supports dispersedly connected to the connecting rod 80.

[0027] In this embodiment, the deep plowing mechanism 3 includes a deep plowing connecting rod 31, a deep plowing rocker 32, a deep plowing shovel 33 and a rotating drive member 34. The deep plowing rocker 32 is hingedly mounted on the mounting seat 11, and the deep plowing shovel 33 is connected to the deep plowing rocker 32 and extends to the bottom of the deep plowing rocker 32. One end of the deep plowing connecting rod 31 is hinged to the deep plowing rocker 32, and the other end of the deep plowing connecting rod 31 is connected to the rotating drive member 34 through an eccentric bearing. The rotary drive member 34 is fixedly connected to the frame 2, and the output end of the rotary drive member 34 is connected to a drive shaft through a coupling. The eccentric bearing is installed on the drive shaft, and the eccentric bearing is embedded in the eccentric bearing seat. There are two ordinary bearing seats on the left and right sides of the eccentric bearing seat to provide support. The deep loosening link 31 is welded to the eccentric bearing seat, and the deep loosening link 31 is hinged to the deep loosening rocker 32. The deep loosening shovel 33 is fixedly connected to the deep loosening rocker 32. The rotary motion generated when the rotary drive member 34 rotates is transmitted to the eccentric bearing through the drive shaft. Under the action of the eccentricity of the eccentric bearing, the eccentric bearing seat will perform eccentric motion. The eccentric bearing seat then transmits the eccentric motion to the deep loosening link 31, and then to the deep loosening rocker 32, and then makes the deep loosening shovel 33 vibrate at a certain frequency, thereby realizing deep loosening operation. The rotary drive member 34 is set as a motor. Since the subsoiler 32 is hinged to the mounting base 11 and is also hinged to the subsoiler connecting rod 31, that is, the connecting rod 80, the subsoiler connecting rod 31, and the subsoiler rocker 32 form a planar connecting rod mechanism. Under the telescopic adjustment of the adjusting cylinder 81, the connecting rod 80 swings back and forth about the hinge point on the frame 2. The subsoiler rocker 32, which has two hinge points, will change its height from the ground and its tilt angle accordingly. At the same time, the motion is transmitted to the subsoiler connecting rod 31, causing the subsoiler connecting rod 31 to swing back and forth about the hinge point on the frame 2. Since the subsoiler 33 is fixedly connected to the subsoiler rocker 32, the subsoiler 33 can also change its height from the ground and its tilt angle, so that the depth of the subsoiler 33 below the surface can be adjusted according to the size of the white radish. In this way, the subsoiler 33 can be adjusted to a subsoil depth of 0-350mm below the surface, thereby improving the effectiveness of the subsoiling operation and ensuring that the white radish can be pulled out smoothly.

[0028] In this embodiment, the leaf-holding mechanism 4 includes a horizontal leaf-holding mechanism 41 and a vertical leaf-holding mechanism 42 located behind the horizontal leaf-holding mechanism 41. The horizontal leaf-holding mechanism 41 and the vertical leaf-holding mechanism 42 are fixedly connected to a connecting frame 43; the horizontal leaf-holding mechanism 41 includes a first sprocket assembly 411, a second sprocket assembly 412 and two first ring chains 413 wound around the first sprocket assembly 411 and the second sprocket assembly 412. The two first ring chains 413 are spaced apart to form a space for accommodating white radish leaves. Each first ring chain 413 is provided with a plurality of first leaf-holding teeth 414 spaced apart. The first leaf-holding teeth 414 extend in the plane where the first ring chain 413 is located. The first sprocket assembly 411 and / or the second sprocket assembly 412 are connected to a first rotating drive member; the vertical leaf-holding mechanism 42 includes two sprocket-type leaf-holding units spaced apart. The sprocket-type leaf-holding unit includes a third sprocket assembly 42 1. The fourth sprocket assembly 422 and the second annular chain 423 wound around the third sprocket assembly 421 and the fourth sprocket assembly 422, the second annular chain 423 is provided with a plurality of second leaf-grabbing teeth 424 arranged at intervals and running through the space between the two sprocket-type leaf-grabbing units in sequence as the second annular chain 423 runs, the third sprocket assembly 421 and / or the fourth sprocket assembly 422 is connected to a second rotating driving member, and the second annular chains 423 of the two sprocket-type leaf-grabbing units have a spacing in the front-to-back direction; the rotation axes of the first sprocket assembly 411 and the second sprocket assembly 412 are arranged horizontally and perpendicular to the traveling direction of the white radish combine harvester, the rotation axes of the third sprocket assembly 421 and the fourth sprocket assembly 422 are perpendicular to the rotation axes of the first sprocket assembly 411 and the second sprocket assembly 412, and the space between the two first annular chains 413 is located directly in front of the space between the two sprocket-type leaf-grabbing units.

[0029] In the horizontal leaf-grabbing mechanism 41, the first sprocket assembly 411 includes two first sprockets, which are arranged at intervals along the central axis and connected via a first transmission shaft. The first rotary drive member is fixedly connected to the connecting frame 43 and transmits motion to the first sprockets via the first transmission shaft, causing the first sprockets to rotate. The second sprocket assembly 412 includes two second sprockets, which are arranged at intervals along the central axis. A first circular chain 413 is wound around the first and second sprockets. Rotation of the first sprocket causes the first circular chain 413 to rotate, which in turn drives the second sprocket to rotate. The first leaf-grabbing teeth 414 rotate with the first circular chain 413. The first leaf-grabbing teeth 414 on the two first circular chains 413 respectively grasp the white radish leaves from the left and right sides, thereby achieving the leaf-grabbing operation. In the vertical leaf-grabbing mechanism 42, the third sprocket assembly 421 includes a third sprocket, the fourth sprocket assembly 422 includes a fourth sprocket, and a second endless chain 423 is wound around the third and fourth sprockets. A second rotary drive member is fixedly connected to the connecting frame 43 and transmits motion to the third sprocket via a chain transmission assembly, rotating the second endless chain 423 and, in turn, the fourth sprocket. The second leaf-grabbing teeth 424 rotate along with the second endless chains 423. The second leaf-grabbing teeth 424 on the two second endless chains 423 grasp the radish leaves on both the front and rear sides, thereby grasping the leaves. Both the first and second endless chains 413 and 423 are configured as single-sided chains with lugs. The first leaf-grabbing teeth 414 are fixedly connected to the lugs of the first endless chain 413, and the second leaf-grabbing teeth 424 are fixedly connected to the lugs of the second endless chain 423. Both the first and second rotary drives are configured as motors. Both the first and second leaf-grabbing teeth 414 and 424 are flexible and can be made of rubber. Because the radish leaves naturally spread out in an "umbrella" shape at a certain angle, when the leaves are being gathered, the radish is located in the soil below the space formed by the two first ring-shaped chains 413, and the corresponding radish leaves are mostly located in the space formed by the two first ring-shaped chains 413. Since the rotation axes of the first sprocket assembly 411 and the second sprocket assembly 412 are arranged horizontally and perpendicular to the travel direction of the radish combine harvester, during the movement of the walking chassis 1, the first leaf-grabbing teeth 414 always gather the leaves in a direction parallel to the travel direction of the radish combine harvester. As the walking chassis 1 moves forward, the radish is located in the soil below the space formed by the two sprocket-type leaf-grabbing units, and the corresponding radish leaves are mostly located in the space formed by the two sprocket-type leaf-grabbing units. Since the rotation axes of the third sprocket assembly 421 and the fourth sprocket assembly 422 are perpendicular to the rotation axes of the first sprocket assembly 411 and the second sprocket assembly 412, during the movement of the walking chassis 1, the second leaf-grabbing teeth 424 always gather the leaves in a direction perpendicular to the travel direction of the radish combine harvester.Through the horizontal leaf-grabbing mechanism 41 and the vertical leaf-grabbing mechanism 42, the leaf-grabbing operation of the radish tops and leaves can be realized from the left and right sides and the front and back sides, realizing multi-directional leaf-grabbing, making the leaf-grabbing range larger and the leaf-grabbing effect better, and being able to gather all the radish tops and leaves on each radish as much as possible, making it convenient for the subsequent first-level clamping and conveying mechanism 5 to clamp more radish tops and leaves so as to pull up the radish, and further ensuring the effect of cutting the radish tops and leaves after clamping and conveying.

[0030] In this embodiment, the connecting frame 43 is mounted on the primary clamping and conveying mechanism 5 via a second height adjustment assembly so that its height can be adjusted. The second height adjustment assembly includes one or more leaf-holding swing arms 45, which are hingedly mounted on the primary clamping and conveying mechanism 5 in a vertically swinging manner. The connecting frame 43 is hingedly connected to the leaf-holding swing arms 45. The second height adjustment assembly also includes a height adjustment mechanism for adjusting the height of the connecting frame 43. The height adjustment mechanism includes a leaf-holding adjustment cylinder 44 and a leaf-holding connecting rod 46, which is hingedly mounted on the frame 2 in a vertically swinging manner. The swinging end of the leaf-holding connecting rod 46 is hingedly connected to the connecting frame 43. The leaf-holding adjustment cylinder 44 is hingedly mounted on the mounting base 11, and the leaf-holding adjustment cylinder 44 is hingedly connected to the leaf-holding connecting rod 46. The connecting frame 43 is hingedly connected to the leaf-holding swing arms 45, which are hingedly connected to the primary clamping and conveying mechanism 5. The connecting frame 43 is hingedly connected to the leaf-holding connecting rod 46, which is hingedly connected to the frame. The connecting frame 43, the leaf-holding swing lever 45, and the leaf-holding connecting rod 46 form a planar linkage mechanism. Because the leaf-holding adjustment cylinder 44 is hingedly connected to the leaf-holding connecting rod 46, the telescopic adjustment of the leaf-holding adjustment cylinder 44 causes the leaf-holding connecting rod 46 to swing back and forth about its hinge point on the frame 2. The connecting frame 43, with its two hinge points, changes its height from the ground and its tilt angle. The horizontal and vertical leaf-holding mechanisms 41 and 42, fixedly connected to the connecting frame 43, move with the connecting frame 43, simultaneously transmitting this motion to the leaf-holding swing lever 45, causing it to swing back and forth about its hinge point on the frame 2. The height adjustment mechanism, employing the leaf-holding adjustment cylinder 44 plus the leaf-holding connecting rod 46, features a simple structure, smooth operation, reliable operation, and easy control. In other embodiments, telescopic cylinders or other mechanical structures can also be used to achieve the up and down reciprocating swing of the leaf-holding connecting rod 46. Because the leaf-holding adjustment cylinder 44 is hinged to the leaf-holding connecting rod 46, which is also hinged to the mounting base 11, and the adjusting cylinder 81 is also hinged to the mounting base 11, under the telescopic adjustment action of the adjusting cylinder 81, the connecting rod 80 and the mounting base 11 fixedly connected to the connecting rod 80 swing back and forth about the hinge point of the connecting rod 80 on the frame 2. The leaf-holding connecting rod 46, which is hinged to the mounting base 11 via the leaf-holding adjustment cylinder 44, can also swing back and forth about the hinge point on the frame 2, thereby moving the horizontal leaf-holding mechanism 41 and the vertical leaf-holding mechanism 42 mounted on the connecting frame 43, thereby changing the height and tilt angle of the leaf-holding mechanism 4 from the ground. By adjusting the cylinder 81, the vertical position height and tilt angle of the leaf-holding mechanism 4 and the deep loosening mechanism 3 can be changed simultaneously, simplifying the operation process and enhancing the applicability. Since the second height adjustment component can also adjust the height and inclination angle of the leaf-holding mechanism 4 from the ground, the leaf-holding mechanism 4 can be adjusted individually by the second height adjustment component, and linkage adjustment can be achieved by adjusting the oil cylinder 81. It can also be adjusted individually on the basis of linkage adjustment, which expands the range of adjustment, enhances applicability, and allows flexible selection.In other embodiments, the leaf-holding mechanism 4 can be directly connected to the walking chassis 1 through a second height adjustment component.

[0031] In this embodiment, the primary clamping and conveying mechanism 5 includes two first clamping and conveying units arranged side by side and at intervals. The first clamping and conveying unit includes a first pulley assembly 51 and a second pulley assembly 52, and a first endless belt 53 wound around the first pulley assembly 51 and the second pulley assembly 52. The first pulley assembly 51 and / or the second pulley assembly 52 are connected to a third rotating drive member. The two first clamping and conveying units are fixedly connected to a support frame 54. The white radish leaves that have been separated from the leaf-holding mechanism 4 are located between the entrance ends formed by the two first clamping and conveying units. The first pulley assembly 51 includes a first pulley, and the second pulley assembly 52 includes a second pulley. The first endless belt 53 is wound around the first pulley and the second pulley. The third rotating drive member is fixedly connected to the support frame 54 and transmits motion to the first pulley through the tooth transmission assembly, causing the first endless belt 53 to rotate and then drive the second pulley to rotate. The gear transmission assembly includes a driving gear and two driven gears. A third rotating drive member is fixedly connected to the driving gear, meshing with the driven gear, which in turn meshes with another driven gear. The two driven gears transmit motion to the two first pulleys via two transmission shafts. The distance between the two first endless belts 53 is set to be sufficient to hold and transport the radish leaves. The third rotating drive member is configured as a hydraulic motor. A plurality of rollers 57 and tensioning pulleys 58 are spaced apart on the support frame 54. Roller 57 is positioned between a first endless belt 53, and tensioning pulley 58 is positioned between another first endless belt 53. Roller 57 and tensioning pulley 58 are used to tension a first endless belt 53 near the section between the other first endless belts 53, effectively keeping the two first endless belts 53 in a constant contact and tensioned state to ensure effective gripping of the radish leaves, facilitating smooth transportation of the radishes and preventing belt slack and radish drop due to excessive transport distances. Preferably, the first endless belts 53 are configured as V-shaped industrial belts.

[0032] In this embodiment, the rear end of the support frame 54 is mounted on the frame 2 in a manner that allows the front end to swing up and down to adjust its height. A third height adjustment assembly for adjusting the swing angle of the support frame 54 is mounted on the mounting base 11. The frame 2 is provided with a height-adjustable mounting base 12. The rear end of the support frame 54 is hingedly connected to the mounting base 12 and can swing up and down about a hinge axis. The mounting base 12 includes a fixed frame 121 and a sliding frame 122 that is sleeved on the fixed frame 121 and slides along the fixed frame 121. A first clamping and conveying adjustment cylinder 55 is hingedly connected to the fixed frame 121 and is hingedly connected to the sliding frame 122. The third height adjustment assembly is a second clamping and conveying adjustment cylinder 56, which is hingedly connected to the mounting base 11 and hingedly connected to the support frame 54. Since the two first clamping and conveying units are fixedly connected to the support frame 54, the rear end of the support frame 54 is mounted on the frame 2 in a manner that allows the front end to swing up and down to adjust its height. Attached to the frame 2 is a mounting frame 12, which includes a fixed frame 121 and a sliding frame 122 that is sleeved onto the fixed frame 121 and slides along the fixed frame 121. The rear end of the support frame 54 is hingedly connected to the sliding frame 122. A first clamping and conveying adjustment cylinder 55 is hingedly connected to the fixed frame 121 and is hingedly connected to the sliding frame 122. The telescopic adjustment of the first clamping and conveying adjustment cylinder 55 enables the sliding frame 122 to slide along the fixed frame 121. The support frame 54 is provided with a third height adjustment assembly, configured as a second clamping and conveying adjustment cylinder 56, which is hingedly connected to the support frame 54. When the first clamping and conveying adjustment cylinder 55 is extended or retracted, the sliding frame 122 slides along the fixed frame 121, and the support frame 54 swings back and forth with the hinge point of the second clamping and conveying adjustment cylinder 56 on the support frame 54 as the axis. When the second clamping and conveying adjustment cylinder 56 is extended or retracted, the support frame 54 can swing back and forth with the hinge point on the sliding frame 122 as the axis, that is, the two first clamping and conveying units and the support frame 54 move together. By combining the second clamping and conveying adjustment cylinder 56 with the first clamping and conveying adjustment cylinder 55 in the form of the mounting frame 12, the height and tilt angle of the support frame 54 from the ground can be adjusted, that is, the height and tilt angle of the primary clamping and conveying mechanism 5 from the ground can be adjusted. Since the second clamping and conveying adjustment cylinder 56 is hinged on the mounting seat 11, the mounting seat 11 is also hinged with an adjusting cylinder 81. Under the telescopic adjustment of the adjusting cylinder 81, the connecting rod 80 and the mounting seat 11 fixedly connected to the connecting rod 80 swing back and forth up and down with the hinge point of the connecting rod 80 on the frame 2 as the axis, so that the first-level clamping and conveying mechanism 5 swings back and forth up and down with the hinge point of the support frame 54 on the sliding frame 122 as the axis, that is, by adjusting the cylinder 81, the upper and lower position heights and inclination angles of the first-level clamping and conveying mechanism 5, the leaf hugging mechanism 4 and the deep loosening mechanism 3 can be changed at the same time, which simplifies the operation process and enhances applicability.The height and inclination angle of the primary clamping and conveying mechanism 5 from the ground can be adjusted using the third height adjustment assembly, and the inclination angle of the primary clamping and conveying mechanism 5 can also be adjusted using the first clamping and conveying adjustment cylinder 55. Furthermore, the third height adjustment assembly and the first clamping and conveying adjustment cylinder 55 can be used in conjunction with each other to increase adjustment flexibility, facilitate better coordination with the front leaf-holding mechanism 4 for clamping and conveying, and help reduce missed leaf removal. Linked adjustment can also be achieved using the adjustment cylinder 81, and individual adjustments can be made based on this linked adjustment, expanding the range of adjustment and enhancing applicability. Because the leaf-holding mechanism 4 is hingedly connected to the primary clamping and conveying mechanism 5 via the leaf-holding swing arm 45, and the leaf-holding connecting rod 46 is hingedly mounted on the frame 2, a four-bar linkage is formed between the leaf-holding mechanism 4, the leaf-holding connecting rod 46, the primary clamping and conveying mechanism 5, and the frame 2. When the primary clamping and conveying mechanism 5 is raised or lowered, the leaf-holding mechanism 4 is also raised or lowered accordingly. In other embodiments, the primary clamping and conveying mechanism 5 can be directly connected to the traveling chassis 1 via the third height adjustment assembly. The use of a first clamping and conveying adjustment cylinder 55 and a second clamping and conveying adjustment cylinder 56 for adjustment provides a simple structure, smooth operation, and ease of control. The combination of the first clamping and conveying adjustment cylinder 55 and the mounting frame 12 provides a sturdy structure that resists deformation, aids support, and makes the overall structure compact and reliable. Preferably, both the fixed frame and the sliding frame are H-shaped square steel frames. In other embodiments, telescopic cylinders or other mechanical structures may also be used.

[0033] In this embodiment, the secondary clamping and conveying mechanism 6 includes two second clamping and conveying units arranged side by side and spaced apart. The second clamping and conveying units include a third pulley assembly 61 and a fourth pulley assembly 62, and a second endless belt 63 wound around the third and fourth pulley assemblies 61 and 62. The two second clamping and conveying units are fixedly connected to a bracket 64 and connected to the primary clamping and conveying mechanism 5 via two sets of chain drive assemblies 65. The cutting mechanism 7 includes an annular cutter 71 mounted on the third pulley assembly 61 behind the secondary clamping and conveying mechanism 6. The third pulley assembly 61 includes a third pulley, the fourth pulley assembly 62 includes a fourth pulley, and the second endless belt 63 is wound around the third and fourth pulleys. The chain drive assembly 65 includes two transmission wheels and an endless transmission chain wound around the two transmission wheels. One transmission wheel is connected to the first pulley via a first linkage shaft, and the other transmission wheel is fixedly connected to the second linkage shaft. The second linkage shaft is fixedly connected to a universal joint, which is fixedly connected to the third pulley. The rotation of the first pulley transmits motion to one of the transmission wheels through the first linkage shaft, which then drives the third pulley to rotate through the annular transmission chain, another transmission wheel, and then a universal joint. The rotation of the third pulley causes the second annular belt 63 to rotate, which in turn drives the fourth pulley to rotate. The primary clamping and conveying mechanism 5 transmits motion to the secondary clamping and conveying mechanism 6 through the chain transmission assembly 65. This has a simple structure, reduces the number of driving components, effectively reduces costs, and can also enable the primary clamping and conveying mechanism 5 and the secondary clamping and conveying mechanism 6 to move at the same speed. In other embodiments, other technologies can be used to replace the chain transmission assembly 65. The distance between the two second annular belts 63 is set to a distance that can clamp and convey white radish fruits. The third rotating drive component is configured as a motor. A plurality of rollers 57 and tensioning pulleys 58 are arranged at intervals on the bracket 64. The roller 57 is located between the second endless belts 63, and the tensioning pulley 58 is located between another second endless belt 63. The rollers 57 and the tensioning pulley 58 are used to tension the second endless belt 63 near a section between the other second endless belts 63, effectively keeping the two second endless belts 63 in a close and tensioned state at all times to ensure effective clamping of the white radish fruits, making the transportation of the white radish smoother, and effectively preventing the white radish from falling due to belt slack caused by the long transportation distance. Preferably, the second endless belt 63 is configured as a V-shaped industrial belt. When the primary clamping and conveying mechanism 5 that clamps the white radish leaves transports the white radish to the entrance end formed by the two second clamping and conveying units, the white radish fruits will be clamped by the secondary clamping and conveying mechanism 6, and the white radish will continue to be transported under the joint clamping of the primary clamping and conveying mechanism 5 and the secondary clamping and conveying mechanism 6. The annular cutter 71 is bolted to the third pulley at the rear. At this time, the white radish fruit has been clamped by the two second annular belts 63. When the white radish needs to be cut from the fruit, the annular cutter 71 can be installed to meet the requirement of post-processing of the white radish without leaving leaves, and the bolt connection facilitates installation and disassembly.

[0034] In this embodiment, the cutting mechanism 7 includes a fixed cutter 72 located below the primary clamping and conveying mechanism 5 and above the secondary clamping and conveying mechanism 6. The fixed cutter 72 is mounted on the secondary clamping and conveying mechanism 6 in an adjustable height manner. The fixed cutter 72 is provided with a mounting assembly comprising a mounting base, a hexagonal shaft having one or more circular holes, and a hexagonal sleeve having corresponding circular holes. The hexagonal shaft is bolted to the bracket 64, the hexagonal sleeve is bolted to the hexagonal shaft, the mounting base is welded to the hexagonal sleeve, and the fixed cutter 72 is bolted to the mounting base. By aligning the circular holes on the hexagonal sleeve with circular holes at different positions on the hexagonal shaft, the mounting position of the hexagonal sleeve can be changed, thereby changing the mounting height of the fixed cutter 72 and thus the cutting position of the fixed cutter 72. This allows the cutter 72 to be cut at different positions of the white radish leaves, meeting different leaf retention requirements. In this embodiment, either the fixed cutter 72 or the annular cutter 71 can be used.

[0035] In addition, the traveling chassis 1 is of existing technology, and any vehicle chassis that can travel can be used, and the frame 2 is fixedly mounted on the traveling chassis 1 .

[0036] The above is only a preferred embodiment of the present invention, and the scope of protection of the present invention is not limited to the above embodiment. For those skilled in the art, improvements and modifications obtained without departing from the technical concept of the present invention should also be considered as the scope of protection of the present invention.
