Description

Technical Field

[0001] This invention relates to inter-plant weeding technology, specifically to an inter-plant weeding device for understory planting. Background Technology

[0002] In the understory planting industry, the growth of weeds between plants is a key issue affecting crop growth. The understory environment is unique, with irregular spacing between crop plants, complex terrain, and often shaded by trees. Traditional weeding methods face many limitations: manual weeding is inefficient, labor-intensive, and can easily damage crop roots when operating in narrow spaces between plants.

[0003] Conventional mechanical weeding devices are mostly suitable for open farmland and are difficult to adapt to the narrow working areas between trees under forest canopies. Furthermore, they often only have a single weeding function and cannot simultaneously complete subsequent operations such as soil tillage and breakup, resulting in a high rate of weed regeneration, difficulty in accurately removing weeds between trees, poor tillage uniformity, and inability to effectively break up compacted soil. Therefore, this invention provides a weeding device for inter-tree planting under forest canopies. Summary of the Invention

[0004] The purpose of this invention is to provide a weeding device for understory planting to solve the problem of weeding between plants in the prior art.

[0006] Furthermore, the output shaft of the drive device is fixedly connected to a drive shaft, and a threaded rod is fixedly installed at the bottom end of the drive shaft; the soil turning mechanism includes a stabilizing frame and a drive rotating rod, the stabilizing frame is detachably fixed to the top surface inside the protective housing, the drive rotating rod is rotatably assembled to the stabilizing frame, and a first gear is provided on the outside of the stabilizing frame, the first gear meshes with the threaded rod, and the first gear is driven through the threaded rod to drive the rotating rod to rotate at high speed, thereby ensuring tillage efficiency.

[0007] Furthermore, the drive rod is externally fixed with multiple sets of seven-tooth discs, which are symmetrically distributed about the center of the stabilizer. Rotary tillage blades are detachably mounted on the seven-tooth discs, and the rotary tillage blades are arranged in a ring array along the center of the seven-tooth discs. The drive rod is used to drive the seven-tooth discs and rotary tillage blades to rotate to achieve uniform tillage of the soil layer.

[0008] Furthermore, the shearing mechanism includes a pad, a guide frame, a moving plate, a gear plate, a progressive push rod, a progressive block, and a main push rod; the pad is fixedly installed in the opening on the end face of the protective housing, and its top surface is provided with a limiting guide groove; the moving plate slides with the limiting guide groove through the limiting slider at the bottom to achieve stable guidance of the moving plate.

[0009] Furthermore, the moving plate meshes with the gear disk, which is rotatably mounted in the through hole of the pad. The advancing push rod is inserted into the circular hole of the gear disk, driving the gear disk to rotate and moving the moving plate. The advancing block is fixed to the end of the advancing push rod and slidably mounted in the guide frame. The guide frame is integrally formed with the inner wall of the pad, ensuring the stability of the advancing push rod's insertion action. The main push rod is rotatably connected to the advancing block. The drive rod is externally provided with a crank cam, which is rotatably connected to the main push rod. The drive rod is used to drive the crank cam to rotate, which can drive the main push rod to push the advancing block to reciprocate, realizing automatic angled shearing between the moving and fixed shears.

[0010] Furthermore, the crushing mechanism includes a rotating shaft, a transmission gear plate, and crushing hooks; the protective housing has a first circular hole on both sides, and the rotating shaft is assembled in the first circular hole through a collar, and the crushing hooks are evenly distributed outside the rotating shaft; the rotating shaft drives the crushing hooks to rotate, which can efficiently crush the soil after tilling.

[0011] Furthermore, it also includes a support rod and a second gear; the protective housing has second circular holes on both sides, and the support rod is assembled in the second circular holes through bearings. The second gear is fixed to the outside of the support rod and meshes with the threaded rod and the transmission gear plate respectively; the second gear is driven by the threaded rod to drive the transmission gear plate and the rotating shaft to rotate automatically, so as to realize the automated operation of the crushing mechanism.

[0012] Furthermore, a dust cover is fixedly installed on the inner wall of the protective shell, which can prevent soil particles generated by the crushing mechanism from splashing outward, ensuring a clean working environment.

[0015] Compared with existing technologies, this application achieves full automation of the weeding-turning-soil-crushing process. The device integrates a shearing mechanism (weed removal), a turning mechanism (soil tillage), and a crushing mechanism (rotary tillage and crushing). Through the linkage of the same drive device, the "weeding, turning, and crushing" operations are completed in one go, improving the efficiency of inter-tree operations under the forest canopy. It adopts the process of "weeding first, then turning, then crushing". The shearing mechanism prioritizes removing surface weeds to avoid entanglement, the turning mechanism deeply tills the soil, and the crushing mechanism refines soil clods, ensuring weeding effectiveness while reducing damage to crop roots. At the same time, the drive rod of the turning mechanism is linked to the shearing mechanism through a crank cam, eliminating the need for an additional power source, simplifying the structure and reducing energy consumption. The shearing mechanism adopts a linkage structure of "crank cam - main push rod - progressive block - toothed disc - moving plate", which converts the rotational motion into the reciprocating shearing action of the moving shear blades, realizing automatic angled shearing and more thorough weed removal.

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] The weeding device for understory planting in the embodiments of the present invention is different from traditional weeding devices, which are mostly suitable for open farmland and are difficult to adapt to the narrow working area between trees under the forest. They often only have a single weeding function and cannot simultaneously complete subsequent operations such as soil turning and breaking up, resulting in a high rate of weed regeneration, difficulty in accurately removing weeds between trees, poor uniformity of turning, and inability to effectively break up compacted soil.

[0029] like Figure 1-10As shown; this solution discloses an inter-plant weeding device for understory planting, including a protective shell 1, a shearing mechanism 2, a driving device 3, a passage 4, a soil turning mechanism 5, and a crushing mechanism 6. A push handle is fixedly installed on the top of the protective shell 1, and rollers are symmetrically arranged on both sides of the protective shell 1. A notch is opened on the end face of the protective shell 1, and the end of the shaft of the roller 8 is fixed to the inner wall of the notch of the protective shell 1, thereby realizing the pushing of the protective shell 1. The soil turning mechanism 5 is rotatably arranged inside the protective shell 1, which can be used to turn the soil. The shearing mechanism 2 is arranged inside the protective shell 1. A movable shearing blade 9 is detachably installed on the outside of the shearing mechanism 2 by bolts. A fixed shearing blade 10 is arranged directly below the movable shearing blade 9, and the fixed shearing blade 10 is fixed to the side of the protective shell 1 by bolts. When the protective shell 1 is pushed, the movable shearing blade 9 and the fixed shearing blade 10 cut weeds. The crushing mechanism 6 is rotatably arranged inside the protective shell 1, and the soil after turning is rotary tilled and crushed by the crushing mechanism 6.

[0030] To enable the soil-tilling mechanism 5 to operate automatically within the protective casing 1 and till the soil, such as... Figure 2-10 As shown; a battery block is fixed on the top surface of the protective housing 1, and the terminal of the battery block is electrically connected to the terminal of the drive device 3. The base of the drive device 3 is fixed on the top surface of the protective housing 1. The output shaft of the drive device 3 is fixed with a drive shaft 11, and the bottom end of the drive shaft 11 is fixed with a threaded rod 12. When the drive device 3 is started, the drive shaft 11 drives the threaded rod 12 to rotate inside the protective housing 1. The soil turning mechanism 5 includes a stabilizing frame 51. The top of the stabilizing frame 51 is detachably fixed to the inner top surface of the protective housing 1 by bolts. A drive rod 52 is rotatably arranged inside the stabilizing frame 51. An integrally formed first gear 53 is arranged outside the drive rod 52, and the first gear 53 is located between the frames of the stabilizing frame 51. When the threaded rod 12 is engaged and the drive device 3 is started, the threaded rod 12 drives the first gear 53 to drive the drive rod 52 to rotate at high speed inside the stabilizing frame 51. A seven-tooth disc 54 is fixedly installed on the outside of the drive rod 52 (in this application, four sets of seven-tooth discs 54 are provided, and the four sets of seven-tooth discs 54 are symmetrical about the center of the stabilizing frame 51). Rotary tillage blades 55 are detachably fixed on the outside of the two sets of seven-tooth discs 54 by bolts (in this application, each set of seven-tooth discs 54 has seven rotary tillage blades 55, and the seven rotary tillage blades 55 are arranged in a ring around the center of the seven-tooth discs 54). When the drive rod 52 rotates at high speed inside the protective shell 1, the advancement of the protective shell 1 can turn over the soil layer through the rotary tillage blades 55.

[0031] In order to achieve the removal and cutting of weeds by the shearing mechanism 2, such as Figure 4-6As shown; a through-hole 4 is provided on the end face of the protective shell 1. The shearing mechanism 2 includes a pad 21, a guide frame 22, a moving plate 27, and a toothed disc 28. The pad 21 is fixedly installed inside the through-hole 4. A limit guide groove is provided on the top surface of the pad 21. A limit slider slides in the limit guide groove. The top of the limit slider is fixed to the bottom surface of the moving plate 27. The movement of the moving plate 27 in the through-hole 4 plays a limiting role. A moving shear blade 9 is detachably installed on the outside of the moving plate 27 by bolts. A fixed shear blade 10 is fixedly installed on the end face of the protective shell 1, and the fixed shear blade 10 is located below the moving shear blade 9. When the protective shell 1 is pushed forward, the moving shear blade 9 and the fixed shear blade 10 will come into contact with the weeds on the soil. When the moving plate 27 moves in the through-hole 4, the moving shear blade 9 and the fixed shear blade 10 work together to remove and cut the weeds.

[0032] The interior of the pad 21 has a through hole 25, and a toothed disc 28 is rotatably disposed in the through hole 25. The teeth of the toothed disc 28 mesh with the bottom teeth of the moving plate 27. When the toothed disc 28 rotates in the through hole 25 in the pad 21, it can drive the moving plate 27 to move on the pad 21.

[0033] like Figure 5-6 As shown; a circular hole 29 is provided inside the gear disk 28. An integrally formed arc-shaped protrusion is provided on the inner wall of the circular hole 29, and the surface of the arc-shaped protrusion fits into the threaded guide groove on the surface of the advancing push rod 26. When the advancing push rod 26 is inserted into the circular hole 29, the gear disk 28 can rotate in the through hole 25 in the pad 21 to drive the moving plate 27 to move above the pad 21. An advancing block 23 is fixed to the end of the advancing push rod 26. The external part of the advancing block 23 is movably set inside the guide frame 22. The end of the guide frame 22 is integrally formed into the inner wall of the pad 21. The movement of the advancing block 23 in the guide frame 22 has a stabilizing effect on the insertion of the advancing push rod 26 into the circular hole 29. The inside of the advancing block 23 is rotatably connected to the main push rod 24 through a pivot pin, so that the advancing block 23 can be moved and its position adjusted in the guide frame 22 by pushing the main push rod 24.

[0034] To achieve the angled cutting between the moving shear blade 9 and the fixed shear blade 10, such as Figure 4-8 As shown, a crank cam 56 is provided on the outside of the drive rod 52. The crank cam 56 is rotatably connected to the main push rod 24 through a pivot pin. Therefore, the drive rod 52 rotates inside the protective housing 1, thereby driving the main push rod 24 to push the advance block 23 to automatically reciprocate and adjust its position within the guide frame 22. Therefore, when the protective housing 1 is pushed during the weeding process, the moving shear blade 9 and the fixed shear blade 10 cooperate to achieve the automatic weeding effect.

[0035] To enable the crushing mechanism 6 to rotate within the protective housing 1 and crush the tilled soil, such as... Figure 2-4As shown; the crushing mechanism 6 includes a rotating shaft 61, a transmission gear 62, and a crushing hook 63. A first circular hole is opened through both sides of the protective housing 1. A shaft collar is fixed in the first circular hole. The inner ring of the shaft collar fixes the end of the rotating shaft 61. The crushing hook 63 is fixedly installed on the outside of the rotating shaft 61 (in this application, the crushing hook 63 is set in multiple groups, and the multiple groups of crushing hooks 63 are evenly distributed on the outside of the rotating shaft 61. The rotation of the rotating shaft 61 in the protective housing 1 thereby crushes the soil turned over by the soil turning mechanism 5 through the crushing hook 63).

[0036] To enable the crushing hook 63 to rotate automatically within the protective housing 1, such as Figure 9-10 As shown; two circular holes are opened through both sides of the protective shell 1. Bearings are fixed in the two circular holes. The inner ring of the bearing is fixed to the outside of the support rod 14. A second gear 13 is fixedly installed on the outside of the support rod 14. The teeth of the second gear 13 mesh with the teeth of the transmission gear disk 62. When the support rod 14 drives the second gear 13 to rotate, the transmission gear disk 62 drives the rotating shaft 61 to rotate within the protective shell 1. The threaded rod 12 meshes with the teeth of the second gear 13, so that the second gear 13 drives the transmission gear disk 62, causing the rotating shaft 61 to rotate automatically within the protective shell 1.

[0037] To prevent soil from splashing, such as Figure 1-2 As shown; a dust cover 7 is fixedly installed on the inner wall of the protective housing 1, thereby preventing soil particles broken by the crushing mechanism 6 from splashing outward from the inside of the protective housing 1.

[0038] Working principle: The battery block on the top surface of the protective shell 1 supplies power to the drive device 3. After the drive device 3 is started, its output shaft drives the drive shaft 11 to rotate synchronously, which in turn drives the threaded rod 12 fixed to the bottom end of the drive shaft 11 to rotate inside the protective shell 1. The threaded rod 12 serves as the core power distribution component, and simultaneously realizes three power transmissions: first, it engages with the first gear 53 of the soil turning mechanism 5; second, it engages with the second gear 13 of the crushing mechanism 6; and third, it indirectly drives the shearing mechanism 2 through the drive rod 52 of the soil turning mechanism 5, thus realizing power distribution output.

[0039] The threaded rod 12 rotates and meshes with the first gear 53, driving the drive rod 52 inside the stabilizing frame 51 of the soil turning mechanism 5 to rotate at high speed; the four sets of symmetrical seven-tooth discs 54 fixed outside the drive rod 52 rotate synchronously, and the seven sets of rotary tillage blades 55 in a ring array on the seven-tooth discs 54 rotate and cut into the soil; the protective shell 1 is pushed (the device can be moved by the push handle, roller and rolling roller 8), and the rotary tillage blades 55 move with the device to complete the soil turning between plants.

[0040] When the drive rod 52 rotates, its external crank cam 56 rotates synchronously, driving the main push rod 24 to reciprocate through the pivot pin; the main push rod 24 pushes the advancing block 23 to slide back and forth in the guide frame 22, thereby driving the advancing push rod 26 to move in the circular hole 29 of the gear plate 28; the arc-shaped protrusion on the inner wall of the circular hole 29 matches the threaded guide groove on the surface of the advancing push rod 26, driving the gear plate 28 to rotate back and forth in the through hole 25 of the pad plate 21; the gear plate 28 meshes with the bottom teeth of the moving plate 27, driving the moving plate 27 to slide along the limiting guide groove of the pad plate 21, so that the moving shear 9 on the moving plate 27 cooperates with the fixed shear 10 fixed on the end face of the protective shell 1, and automatically cuts weeds as the device moves.

[0041] The threaded rod 12 rotates and meshes with the second gear 13, driving the support rotating rod 14 to rotate within the bearings on both sides of the protective housing 1; the second gear 13 meshes with the transmission gear 62 of the crushing mechanism 6, driving the rotating shaft 61 to rotate within the collar of the protective housing 1; multiple sets of crushing hooks 63 outside the rotating shaft 61 rotate synchronously to rotary crush the tilled soil clods, thereby refining the soil.

[0042] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
