Description

Technical Field

[0001] This invention relates to the field of weeding machinery technology, and in particular to a weeding mechanism with multiple usage modes. Background Technology

[0002] With the development of agricultural mechanization, weeding machinery plays a vital role in agricultural production, greatly improving weeding efficiency and quality. Currently, weeding equipment on the market mainly includes rotary mowers and reciprocating mowers, each suitable for specific types of lawns or weed control tasks. However, these traditional devices generally suffer from a significant problem: each type is typically only suitable for one or a limited number of specific work scenarios, such as large-area lawn maintenance or the removal of specific types of weeds. When faced with different types of weeds or different working environments, it is often necessary to replace or adjust the equipment, or even purchase specially designed weeders to meet the needs. This not only increases costs but also limits operational flexibility. Furthermore, for deep weeding or high-quality surface weeding, existing equipment struggles to simultaneously meet the requirements of efficiency and quality, leading to problems such as low work efficiency or incomplete weeding.

[0003] In the prior art, patents such as CN111819921A and CN 211210395 U disclose weeders with multiple weeding mechanisms arranged in a linear array. Each weeding mechanism includes a blade disc, a drive shaft, and cutters mounted on the blade disc. The drive shafts are driven by gears to rotate synchronously. Such weeders have the problem of limited application scenarios and limited applicability. Summary of the Invention

[0004] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides a weeding mechanism with multiple usage modes that can meet a wide range of weeding needs and has broad applicability.

[0005] Technical Solution: To achieve the above objectives, the present invention provides a multi-mode weeding mechanism, comprising a mechanism base and multiple sets of mowing mechanisms mounted on the mechanism base; all the mowing mechanisms can be arranged in a straight line, and the power supplied to one set of mowing mechanisms can be transmitted to the other mowing mechanisms via a gear set; the mechanism base is a shell structure, and the gear set is mounted inside the mechanism base; the gear set includes a first gear coaxially fixed with the rotating shaft of each mowing mechanism;

[0006] The mechanism base includes a central section and two side sections; each side section can rotate and fold relative to the central section, allowing the mechanism base to switch between a straight-line shape and a folded shape; when the mechanism base is in a straight-line shape, the central section and all the side sections are collinear, and all the mowing mechanisms are arranged in a straight line; when the mechanism base is in a folded shape, all the side sections rotate and fold relative to the central section, and all the mowing mechanisms are arranged in two rows, front and back, with the two rows of mowing mechanisms staggered to the left and right, and no two sets of mowing mechanisms are aligned front and back.

[0007] The mechanism base is equipped with power output structures at both ends and on the sides, ensuring that the power supplied can drive all the mowing mechanisms to operate simultaneously regardless of the base's orientation. Specifically, when the base is in a straight position, the power output structures at both ends transmit power to the mowing mechanisms on the sides; when the base is in a folded position, the output structures on the sides transmit power to the mowing mechanisms on the sides.

[0008] When weeding requirements are low and large-scale weeding is required, adjust the base of the mechanism to a straight line, with all mowing mechanisms having the same structure and height. This allows for wide-area weeding and improves efficiency. When weeding requirements are high and surface weeding is required, adjust the base of the mechanism to a folded position, with all mowing mechanisms having the same structure and height. In this case, because the front and rear rows of mowing mechanisms are staggered in the left and right direction, their mowing areas overlap, thus effectively improving the quality of weeding and ensuring the flatness of the lawn after weeding. When deep weeding is required, adjust the base of the mechanism to a folded position, with the front and rear rows of mowing mechanisms having different structures and / or different working heights. In this way, the front row of mowing mechanisms mainly completes the surface weeding work, while the rear row of mowing mechanisms completes the root removal work, which can improve the weeding effect.

[0009] Furthermore, each end of the middle portion is equipped with a first mating gear, and each first mating gear meshes with the first gear located at both ends of the middle portion; when the mechanism base is in a straight line shape, the first gear located at the end of the side portion meshes with the first mating gear.

[0010] The middle section has two lateral openings on its sides, and each side has a second mating gear extending out of the housing; when the mechanism base is in a folded state, the second mating gear extends into the lateral opening to mesh with one of the first gears inside the mechanism base.

[0011] Furthermore, a first transition gear is provided between each two adjacent first gears in the intermediate portion; a second transition gear is provided between each two adjacent first gears in the intermediate portion, and the second mating gear meshes with the second transition gear.

[0012] In actual use, a cover plate can be installed on the docking mechanism of the middle part and the side. When the docking mechanism is not needed, the cover plate can be installed on the corresponding opening position on the middle part and the side to prevent dust from entering the mechanism base.

[0013] Furthermore, the mechanism base has a first connecting ear and a second connecting ear; the side has a third connecting ear and a fourth connecting ear;

[0014] When the mechanism base is in a straight shape, the third connecting ear on the side is connected to the first connecting ear in the middle part by a screw; when the mechanism base is in a folded shape, the fourth connecting ear on the side is connected to the second connecting ear in the middle part by a screw.

[0015] This allows for easy disassembly and fixing of both the middle and side sections.

[0016] Furthermore, the side portion has a pivot portion; the middle portion is fixed with a hinge lug that rotatably engages with the pivot portion.

[0017] Furthermore, the mowing mechanism includes mowing components mounted on the rotating shaft; the mowing components can take three forms: a swivel mowing mechanism, a milling mechanism, and a flexible strip mechanism. In use, a suitable mowing component or combination of mowing components is selected according to the type of grass and the nature of the operation. The swivel mowing mechanism and the flexible strip mechanism are generally used to remove or trim grass from the ground surface. The swivel mowing mechanism is suitable for weeding hard weeds, while the flexible strip mechanism is suitable for weeding hard-textured weeds. The milling mechanism can turn over the soil and remove the roots of the grass.

[0018] When performing the above-mentioned deep weeding operation, the mechanism base is adjusted to a folding form, with a sling-and-spin mechanism or flexible strip mechanism installed on the front shaft and a milling and reaming mechanism installed on the rear shaft. In this way, the front and rear cutting mechanisms each perform their respective functions, resulting in good weeding effect.

[0019] Furthermore, the tool-spinning mechanism includes a centrally located first tool disc and a plurality of hardened blades rotatably mounted relative to the first tool disc.

[0020] Furthermore, the milling mechanism includes a tool holder and a plurality of milling cutters fixed on the tool holder; the cutter bodies of the milling cutters are arranged vertically.

[0021] Furthermore, the flexible strip mechanism includes a second cutter head and a plurality of rubber strips with their ends fixed to the second cutter head.

[0022] Furthermore, the height of the rotating shaft can be adjusted.

[0023] Specifically, an adjustment mechanism corresponding to each rotating shaft is installed on the upper end of the mechanism base; the adjustment mechanism includes an outer sleeve fixed relative to the mechanism base, and a sliding body and a pressure plate that can slide relative to it are installed inside the outer sleeve. The pressure plate is placed above the sliding body, and a spring is provided between the two; a disc body is fixed to the upper end of the rotating shaft, and the rotating shaft can slide up and down relative to the corresponding first gear. A sliding key is provided between the two. The sliding body includes an upper clamping plate and a lower clamping plate; the disc body is placed between the upper clamping plate and the lower clamping plate; the lower clamping plate can be adjusted up and down relative to the outer sleeve and fixed. Specifically, the outer sleeve has multiple adjustment holes, and screws passing through the adjustment holes fix the lower clamping plate relative to the outer sleeve; the upper clamping plate can be fixed relative to the lower clamping plate and can also be detached from the upper clamping plate; an adjustment knob acting on the disc body is installed on the top of the outer sleeve.

[0024] The aforementioned adjustment mechanism allows for the modification of the cutting mechanism's operating mode as needed. When the upper clamping plate is fixed relative to the lower clamping plate, and the lower clamping plate is fixed relative to the outer sleeve, the height of the cutting mechanism is fixed and does not affect the rotation of the shaft. When the upper clamping plate disengages from the lower clamping plate, and the lower clamping plate is fixed relative to the outer sleeve, the shaft can elastically float up and down. The initial height of the shaft can be changed by adjusting the position of the lower clamping plate, and the stiffness of the spring can be changed by adjusting the position of the disc body.

[0025] Beneficial effects: The multi-mode weeding mechanism of the present invention has the following beneficial effects:

[0026] (1) By changing the shape of the mechanism base and adjusting the form and installation height of the mowing mechanism, different weeding needs can be met, and it is highly adaptable.

[0027] (2) By setting power output structures at different positions in the middle part, the mechanism base can be in different forms, and all mowing mechanisms are driven by the same power source, reducing the number of power sources to reduce costs and reduce machine weight.

[0028] (3) It can select appropriate cutting blade components or combinations of cutting blade components according to the type of grass and the nature of the operation, and adjust the height of the cutting blade components to improve the quality of the operation. Attached Figure Description

Detailed Implementation

[0042] The invention will now be further described with reference to the accompanying drawings.

[0043] like Figure 1The multi-mode weeding mechanism shown includes a mechanism base 1 and multiple sets of mowing mechanisms 2 mounted on the mechanism base 1; all the mowing mechanisms 2 can be arranged in a straight line, and the power input to one set of mowing mechanisms 2 can be transmitted to the other mowing mechanisms 2 via a gear set; the mechanism base 1 is a shell structure, and the gear set is installed inside the mechanism base 1; as shown Figure 4 As shown, the gear set includes a first gear 31 that is coaxially fixed with the shaft 21 of each of the mowing mechanisms 2;

[0044] The mechanism base 1 includes a central portion 1a and two side portions 1b; each side portion 1b is rotatable and foldable relative to the central portion 1a, allowing the mechanism base 1 to switch between a straight shape and a folded shape; for example Figure 1 and Figure 3 As shown, when the mechanism base 1 is in a straight line shape, the middle part 1a is collinear with all the side parts 1b, and all the lawn mowing mechanisms 2 are arranged in a straight line; as Figure 5 As shown, when the mechanism base 1 is in a folded state, all the side parts 1b are rotated and folded relative to the middle part 1a, and all the mowing mechanisms 2 are arranged in two rows, front and back, and the two rows of mowing mechanisms 2 are staggered in the left and right directions, and no two sets of mowing mechanisms 2 are aligned front and back.

[0045] The mechanism base 1 is equipped with power output structures at both ends and on the sides, so that the power supplied to the mechanism base 1 can drive all the mowing mechanisms 2 to operate simultaneously when the mechanism base 1 is in different configurations. Specifically, when the mechanism base 1 is in a straight position, the power output structures at both ends of the mechanism base 1 transmit power to the mowing mechanism 2 on the side 1b; when the mechanism base 1 is in a folded position, the output structure on the side of the mechanism base 1 transmits power to the mowing mechanism 2 on the side 1b.

[0046] By adopting the above structure, and by changing the shape of the mechanism base 1 and adjusting the form and installation height of the mowing mechanism 2, different weeding needs can be met, demonstrating strong adaptability. When the weeding requirement is low and large-area weeding is required, the mechanism base 1 is adjusted to a straight line shape, with all mowing mechanisms 2 having the same structure and height, thus enabling wide-area weeding and improving weeding efficiency. When the weeding requirement is high and surface weeding is required, the mechanism base 1 is adjusted to a folded shape, with all mowing mechanisms 2 having the same structure and height. In this case, since the front and rear rows of mowing mechanisms 2 are staggered in the left and right direction, the mowing range of the mowing mechanisms 2 overlaps, thus effectively improving the quality of weeding and ensuring the flatness of the lawn after weeding. When deep weeding is required, the mechanism base 1 is adjusted to a folded shape, and the front and rear rows of mowing mechanisms 2 have different structures and / or different working heights. In this way, the front row of mowing mechanisms 2 mainly completes the surface weeding work, while the rear row of mowing mechanisms 2 completes the root removal work, which can improve the weeding effect.

[0047] By setting power output structures at different positions in the middle part 1a, the mechanism base 1 can be in different configurations, and all the mowing mechanisms 2 can be driven by the same power source, reducing the number of power sources to reduce costs and reduce the weight of the machine.

[0048] Preferably, a first mating gear 32 is installed at both ends of the middle portion 1a, and each first mating gear 32 meshes with the first gear 31 located at both ends of the middle portion 1a; when the mechanism base 1 is in the form of a straight line, the first gear 31 located at the end of the side portion 1b meshes with the first mating gear 32.

[0049] The middle portion 1a has two lateral openings 1c on its sides, and each side portion 1b has a second mating gear 33 extending out of the housing; as Figure 6 As shown, when the mechanism base 1 is in a folded state, the second mating gear 33 extends into the lateral opening 1c to mesh with one of the first gears 31 inside the mechanism base 1.

[0050] Preferably, a first transition gear 34 is provided between each two adjacent first gears 31 within the intermediate portion 1a; a second transition gear 35 is provided between each two adjacent first gears 31 within the intermediate portion 1a, and the second mating gear 33 meshes with the second transition gear 35. One of the first transition gears 34 is connected to the power input shaft 5 to receive power.

[0051] In actual use, a cover plate can be installed on the docking mechanism of the middle part 1a and the side part 1b. When the docking mechanism is not needed, the cover plate can be installed on the corresponding opening positions on the middle part 1a and the side part 1b to prevent dust from entering the mechanism base 1.

[0052] Preferably, the mechanism base 1 has a first connecting ear 1d and a second connecting ear 1e; the side portion 1b has a third connecting ear 1f and a fourth connecting ear 1g;

[0053] like Figure 2 As shown, when the mechanism base 1 is in a straight line shape, the third connecting lug 1f of the side portion 1b is connected to the first connecting lug 1d of the middle portion 1a by a screw; as Figure 7 As shown, when the mechanism base 1 is in a folded state, the fourth connecting ear 1g of the side part 1b is connected to the second connecting ear 1e of the middle part 1a by screws.

[0054] This allows for easy disassembly and fixation of both the middle part 1a and the side part 1b.

[0055] Preferably, such as Figure 2 As shown, the side portion 1b has a pivot portion 11; the middle portion 1a is fixed with a hinge lug 12 that rotatably engages with the pivot portion 11.

[0056] Preferably, the mowing mechanism 2 includes a mowing assembly mounted on the rotating shaft 21; the mowing assembly can take the form of three types: a swivel mowing mechanism 22, a milling mechanism 23, and a flexible strip mechanism 24. In use, a suitable mowing assembly or combination of swivel mowing assemblies is selected according to the type of grass and the nature of the operation. The swivel mowing mechanism 22 and the flexible strip mechanism 24 are generally used to remove or trim grass from the ground surface. The swivel mowing mechanism 22 is suitable for weeding hard weeds, while the flexible strip mechanism 24 is suitable for weeding hard-textured weeds. The milling mechanism 23 can turn over the soil and remove the roots of the grass.

[0057] When performing the above-mentioned deep weeding operation, the mechanism base 1 is adjusted to a folding form. The front row of rotating shafts 21 is equipped with a sling-off mechanism 22 or a flexible strip mechanism 24, and the rear row of rotating shafts 21 is equipped with a milling mechanism 23. In this way, the front and rear cutting mechanisms 2 each perform their respective functions, resulting in good weeding effect.

[0058] like Figure 8 As shown, the blade-spinning mechanism 22 includes a centrally located first blade disc 22a and a plurality of hard blades 22b rotatably mounted relative to the first blade disc 22a.

[0059] like Figure 1 As shown, the milling mechanism 23 includes a tool holder 23a and a plurality of milling blades 23b fixed on the tool holder 23a; the blades of the milling blades 23b are arranged vertically.

[0060] like Figure 9As shown, the flexible strip mechanism 24 includes a second cutter head 24a and a plurality of rubber strips 24b with their ends fixed to the second cutter head 24a.

[0061] Preferably, the height of the rotating shaft 21 can be adjusted.

[0062] Specifically, an adjustment mechanism 4 corresponding to each rotating shaft 21 is installed on the upper end of the mechanism base 1; such as Figure 10 and Figure 11 As shown, the adjusting mechanism 4 includes an outer sleeve 41 fixed relative to the mechanism base 1. A sliding body and a pressure plate 42, which can slide relative to the outer sleeve 41, are installed inside the outer sleeve 41. The pressure plate 42 is positioned above the sliding body, and a spring 43 is provided between them. A disc body 44 is fixed to the upper end of the rotating shaft 21. The rotating shaft 21 can slide up and down relative to the corresponding first gear 31, and a sliding key is provided between them. The sliding body includes an upper clamping plate 45 and a lower clamping plate 46. The disc body 44 is positioned between the upper clamping plate 45 and the lower clamping plate 46. The lower clamping plate 46 can be adjusted up and down relative to the outer sleeve 41 and then fixed. Specifically, the outer sleeve 41 has multiple adjusting holes, and screws passing through the adjusting holes fix the lower clamping plate 46 relative to the outer sleeve 41. The upper clamping plate 45 can be fixed relative to the lower clamping plate 46. Figure 12 (When both are in a relatively fixed state), it can also be separated from the upper clamping plate 45; the top of the outer sleeve 41 is equipped with an adjustment knob 47 that acts on the plate body 44.

[0063] By employing the aforementioned adjustment mechanism 4, the working mode of the cutting mechanism 2 can be changed as needed. When the upper clamping plate 45 is fixed relative to the lower clamping plate 46, and the lower clamping plate 46 is fixed relative to the outer sleeve 41, the height of the cutting mechanism 2 is fixed and does not affect the rotation of the rotating shaft 21. When the upper clamping plate 45 disengages from the lower clamping plate 46, and the lower clamping plate 46 is fixed relative to the outer sleeve 41, the rotating shaft 21 can elastically float up and down. The initial height of the rotating shaft 21 can be changed by adjusting the position of the lower clamping plate 46, and the stiffness of the spring 43 can be changed by adjusting the position of the disc body 44.

[0064] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
