The lower end of the reciprocating moving unit extends to the bottom of the protective box and is fixedly connected to a hollow disc. The lower end of the hollow disc is close to the cutting component. Anti-winding levers are evenly installed on the side wall of the hollow disc.

[0008] The positive and progressive effects of this invention are as follows:

[0009] 1. Integrating multiple functions such as height adjustment, leaf storage, air blowing, cutting, leaf gathering, and anti-tangling into one device, forming a complete peanut leaf trimming system, the various functional components work together to achieve efficient and high-quality peanut leaf trimming operations;

[0010] 2. The cutting component and leaf-gathering component of this invention enable mechanized leaf-pruning operations, reducing the labor burden on farmers and improving production efficiency; the reciprocating anti-entanglement lever promptly removes entangled materials, ensuring the normal operation of the equipment; considering the complexity and diversity of agricultural production environments, a flexible height adjustment component and leaf-gathering component are designed, enabling the equipment to adapt to peanut plants at different growth stages and planting densities, filling the gap in leaf-pruning machines and meeting the needs of actual agricultural production.

[0032] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0033] Example 1:

[0034] like Figures 1 to 7 As shown, a peanut leaf trimming machine includes symmetrically arranged frame plates 1. Wheels 2 are rotatably mounted on the sides of the frame plates 1. Height adjustment components 3 are symmetrically arranged on the upper end of the frame plates 1. A carrying platform 4 is fixedly connected to the upper end of the height adjustment components 3.

A handrail 10 is fixedly installed in the middle of the side wall of the carrying platform 4 away from the cutting component 7.

[0035] The height adjustment assembly 3 includes upright plates 31 symmetrically installed at the ends of the frame plate 1. Liners 32 are symmetrically installed on the side walls of the upright plates 31 near the upper end. An adjustment shaft 33 is rotatably installed in the middle of the liner 32. A knob 34 is fixedly installed at the end of the adjustment shaft 33. An adjustment gear 35 is fixedly installed on the adjustment shaft 33 between the liners 32. A vertical rack 36 meshes with the side of the adjustment gear 35. The vertical rack 36 is fixedly installed on the side wall of the support column 37. A support spring 38 is installed between the lower end of the support column 37 and the support platform 4.

[0036] The leaf storage assembly 5 includes a bracket 51 fixedly installed at the upper end of the support platform 4. A leaf storage net bag 52 is connected to the inner side of the bracket 51. Several reinforcing rings 53 are provided on the body of the leaf storage net bag 52. A sliding rod 54 is fixedly connected to the middle of the side wall of the reinforcing ring 53.

[0037] The bracket 51 has a horizontal bar 511 fixedly installed on its side wall. A limiting slide 512 is provided in the middle of the horizontal bar 511, and the slide rod 54 is slidably installed in the limiting slide 512.

[0038] The air blowing assembly 6 includes a fixing member 61 symmetrically connected to the bracket 51. An airflow main pipe 62 is fixedly installed inside the fixing member 61. Air nozzles 63 are evenly installed at the bottom of the airflow main pipe 62. The airflow main pipe 62 is connected to a fan 65 through an air guide pipe 64. The fan 65 is fixedly installed on the upper end of the fan mounting plate 66. The fan mounting plate 66 is fixedly connected to the side of the bearing platform 4.

[0039] The fan mounting plate 66 is provided with a battery module 11 located on the side of the fan 65.

[0040] The cutting assembly 7 includes a motor mounting plate 71 fixedly connected to the side of the support platform 4. A servo motor 72 is fixedly mounted on the upper end of the motor mounting plate 71. A drive disk 73 is fixedly connected to the output shaft of the servo motor 72. A pull rod 74 is hinged to the side wall of the drive disk 73 near the outer edge. A moving blade 75 is hinged to the lower end of the pull rod 74. The moving blade 75 is slidably mounted on a blade clamping plate 77. The blade clamping plate 77 is fixedly mounted on the head of the support platform 4. Fixed blades 76 are staggered on the blade clamping plate 77.

[0041] The aforementioned leaf-gathering assembly 8 includes an elastic metal plate 81 fixedly mounted on the frame plate 1. A leaf-gathering cone 82 is fixedly mounted on the lower end of the elastic metal plate 81. A crankshaft 83 is installed through the middle of the elastic metal plate 81. Threaded sections are provided at both ends of the crankshaft 83. Adjusting nuts 84 are screwed onto the threaded sections. A baffle 85 is fixedly mounted on the crankshaft 83 at the end of the threaded section. A helical spring 86 is sleeved on the crankshaft 83 between the baffle 85 and the elastic metal plate 81.

[0042] In actual operation, the peanut leaf cutter is first moved to the peanut field to be harvested, so that the leaf gathering component 8 is facing the peanut seedling ridge. Then, the peanut leaf cutter is moved forward by manually pushing the handle frame 10, and the walking wheels 2 walk between the furrows.

[0043] During the forward movement, the distance between the two leaf-gathering cones 82 on the left and right is adjusted manually according to the horizontal harvesting width of the peanut seedlings. The adjustment process is as follows: by manually rotating the adjusting nut 84, the elastic metal plate 81 will drive the leaf-gathering cones 82 on both sides to move closer or separate under the action of its own elasticity and the spiral spring 86, so that the peanut plants can move closer to the middle, which is convenient for the cutting component 7 to cut. During the cutting process, the leaf-gathering cones 82 can straighten the peanut plants and improve the cutting efficiency.

[0044] Start the servo motor 72, which drives the drive disk 73 to rotate. The pull rod 74 pulls the moving blade 75 up and down as the drive disk 73 rotates. The moving blade 75 slides on the blade clamp 77 and cooperates with the fixed blade 76 to cut the peanut leaves.

[0045] Start the blower 65 and spray air into the main airflow duct 62. The airflow is then sprayed out through the nozzle 63, which blows the cut peanut leaves into the storage bag 52 for easy collection. As the cutting operation continues, the peanut leaves will accumulate at the entrance of the storage bag 52. At this time, the reinforcing ring 53 can be manually pulled backward to move the storage bag 52. The storage bag 52 will slide along the limiting slide 512 on the side wall crossbar 511 of the support 51, thereby unfolding the storage bag 52 to accommodate different peanut leaf collection volumes.

[0046] When encountering field ridges of different heights, the operator can adjust the height of the bearing platform 4 according to the actual height. The specific adjustment process is as follows: by manually turning the knob 34, the adjusting shaft 33 is driven to rotate, which in turn causes the adjusting gear 35 to rotate. Through the meshing action between the adjusting gear 35 and the vertical rack 36, the bearing column 37 is driven to move up and down, thereby realizing the height adjustment of the bearing platform 4. The support spring 38 plays an auxiliary support and buffering role.

[0047] Example 2:

[0048] The technical solution is basically the same as that in Embodiment 1, see below. Figure 1 , Figure 2 , Figure 8 and Figure 9The difference lies in that: the cutting component 7 is equipped with an anti-winding component 9 on its side, the anti-winding component 9 includes a connecting frame plate 91, the upper end of the leaf storage component 5 is symmetrically provided with the connecting frame plate 91, the end of the connecting frame plate 91 is fixedly connected to the protective box 92, the bottom of the protective box 92 is provided with a reciprocating moving unit 93, the lower end of the reciprocating moving unit 93 extends to the lower part of the protective box 92 and is fixedly connected to a hollow disc 94, the lower end of the hollow disc 94 is close to the cutting component 7, and anti-winding levers 95 are evenly installed on the side wall of the hollow disc 94.

[0049] The reciprocating moving unit 93 includes a strip-shaped through groove 931 formed at the bottom and top of the protective box 92. A transverse rack 932 is fixedly installed on the side of the strip-shaped through groove 931. A drive gear 933 meshes with the side of the transverse rack 932. The drive gear 933 is fixedly installed on a stepped shaft 934. The stepped shaft 934 is slidably installed in the strip-shaped through groove 931 at the bottom of the protective box 92. A drive motor 935 is fixedly connected to the upper end of the stepped shaft 934. The upper end of the drive motor 935 is slidably installed in the strip-shaped through groove 931 at the top of the protective box 92.

[0050] In practice, during the peanut leaf cutting process, the drive motor 935 is started, which drives the stepped shaft 934 to rotate, thereby driving the hollow disc 94 and the anti-tangling lever 95 to rotate. The anti-tangling lever 95 can push the peanut leaves piled up at the entrance of the leaf storage bag 52 into its interior, and at the same time, it can push away the peanut vines stuck on the cutting component 7 to prevent the cutting component 7 from getting stuck. During the rotation of the stepped shaft 934, it also drives the drive gear 933 to rotate. Due to the action of the transverse rack 932, the drive motor 935 will also cause the stepped shaft 934, the hollow disc 94 and the anti-tangling lever 95 to reciprocate along the strip groove 931, thereby adapting to cutting areas of different widths.

[0051] The working principle of this invention during use:

[0052] First, move the peanut leaf cutter to the peanut field to be harvested, so that the leaf gathering component 8 is facing the peanut seedling ridge. Then, manually push the handle frame 10 to move the peanut leaf cutter forward as a whole, and the walking wheels 2 walk between the furrows.

[0053] During the forward movement, the distance between the two leaf-gathering cones 82 on the left and right is adjusted manually according to the horizontal harvesting width of the peanut seedlings. The adjustment process is as follows: by manually rotating the adjusting nut 84, the elastic metal plate 81 will drive the leaf-gathering cones 82 on both sides to move closer or separate under the action of its own elasticity and the spiral spring 86, so that the peanut plants can move closer to the middle, which is convenient for the cutting component 7 to cut. During the cutting process, the leaf-gathering cones 82 can straighten the peanut plants and improve the cutting efficiency.

[0054] During cutting, the servo motor 72 is started, which drives the drive disk 73 to rotate. The pull rod 74 pulls the moving blade 75 up and down as the drive disk 73 rotates. The moving blade 75 slides on the blade clamp 77 and cooperates with the fixed blade 76 to cut the peanut leaves.

[0055] While the cutting process is underway, the blower 65 is started, and air is sprayed into the main airflow duct 62 through the blower 65. Then the airflow is sprayed out through the nozzle 63, which blows the cut peanut leaves into the storage bag 52 to facilitate the collection of peanut leaves. As the cutting operation continues, peanut leaves will accumulate at the entrance of the storage bag 52. At this time, the reinforcing ring 53 can be manually pulled backward to move it backward. At this time, the storage bag 52 will slide along the limiting slide 512 on the side wall crossbar 511 of the support 51, so that the storage bag 52 unfolds to accommodate different peanut leaf collection volumes.

[0056] During the above process, the drive motor 935 is started, which drives the stepped shaft 934 to rotate, thereby driving the hollow disc 94 and the anti-tangling lever 95 to rotate. The anti-tangling lever 95 can push the peanut leaves piled at the entrance of the leaf storage bag 52 into its interior, and at the same time, it can push away the peanut vines stuck on the cutting component 7 to prevent the cutting component 7 from getting stuck. During the rotation of the stepped shaft 934, it will also drive the drive gear 933 to rotate. Due to the action of the transverse rack 932, the drive motor 935 will also cause the stepped shaft 934, the hollow disc 94 and the anti-tangling lever 95 to reciprocate along the strip groove 931, thereby adapting to cutting areas of different widths.

[0057] It should be noted that in actual use, the operator can adjust the height of the bearing platform 4 according to the different heights of the ridges. The specific adjustment process is as follows: by manually turning the knob 34, the adjusting shaft 33 is rotated, which in turn causes the adjusting gear 35 to rotate. Through the meshing action between the adjusting gear 35 and the vertical rack 36, the bearing column 37 is moved up and down. The support spring 38 plays an auxiliary support and buffering role, thereby realizing the height adjustment of the bearing platform 4 to adapt to peanut ridges of different heights. Due to the presence of the support spring 38, the peanut leaf cutter can still be used normally even when the heights of the ridges on both sides are not at the same level.
