Description

Technical Field

[0001] The invention relates to the technical field of weeding machinery, in particular to a weeding mechanism with multiple usage modes. Background Art

[0002] With the development of agricultural mechanization, weeding machinery plays an important role in agricultural production, greatly improving the efficiency and quality of weeding. The weeding equipment on the current market mainly includes rotary mowers, reciprocating mowers, etc., each of which is suitable for specific types of grassland or weed treatment tasks. However, these traditional equipment generally have a significant problem: each device is usually 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, which not only increases costs, but also limits operational flexibility. In addition, for deep weeding or high-demand surface weeding work, it is difficult for existing equipment to take into account both efficiency and quality requirements at the same time, resulting in problems such as low work efficiency or incomplete weeding.

[0003] In the prior art, patents such as CN111819921A and CN 211210395 U disclose a lawn mower with multiple weeding mechanisms arranged in a linear array, each of which includes a blade disc, a transmission shaft, and a cutter mounted on the blade disc, and the transmission shafts are driven by gears to rotate synchronously. This type of lawn mower has the problem of single usage scenario and limited applicability. Summary of the invention

[0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a weeding mechanism with multiple usage modes that can meet a variety of weeding needs and has wide applicability.

[0005] Technical solution: To achieve the above-mentioned purpose, the multi-use mode weeding mechanism of the present invention comprises a mechanism base and a plurality of mowing mechanisms mounted on the mechanism base; all the mowing mechanisms can be arranged in a straight line, and the power connected to one group of mowing mechanisms can be transmitted to other mowing mechanisms through a gear set; the mechanism base is a shell structure, and the gear set is mounted in the mechanism base; the gear set comprises a first gear coaxially fixed to the rotating shaft of each mowing mechanism;

[0006] The mechanism base includes a middle part and two side parts; each of the side parts can be rotated and folded relative to the middle part, so that the mechanism base can be switched between a straight line shape and a folded shape; when the mechanism base is in a straight line shape, the middle part and all the side parts are in a straight line, and all the mowing mechanisms are arranged in a straight line; when the mechanism base is in a folded shape, all the side parts are rotated and folded relative to the middle part, and all the mowing mechanisms are arranged in two rows, front and back, and the two rows of mowing mechanisms are staggered in the left and right directions, and no two groups of mowing mechanisms are aligned front and back;

[0007] The two ends and the side of the mechanism base are provided with power output structures, so that when the mechanism base is in different forms, the connected power can drive all the mowing mechanisms to operate simultaneously. Specifically, when the mechanism base is in a straight line form, the power output structures at the two ends of the mechanism base transmit power to the mowing mechanisms on the side; when the mechanism base is in a folded form, the output structures on the side of the mechanism base transmit power to the mowing mechanisms on the side.

[0008] When the weeding requirement is low and a large area of ​​weeding is to be carried out, the mechanism base is adjusted to a straight line shape, and the structure and height of all mowing mechanisms are the same, so that wide-area weeding can be carried out and the weeding efficiency is improved; when the weeding requirement is high and surface weeding is to be carried out, the mechanism base is adjusted to a folded shape, and the structure and height of all mowing mechanisms are the same. At this time, since the front and rear rows of mowing mechanisms are staggered in the left and right directions, the mowing ranges of the mowing mechanisms overlap, and therefore, the weeding quality can be effectively improved to ensure the flatness of the lawn after weeding; when deep weeding is required, the mechanism base is adjusted to a folded shape, and the structures of the front and rear rows of mowing mechanisms are different and / or the operating heights are different, so that the front row of mowing mechanisms mainly completes the surface weeding operation, and the rear row of mowing mechanisms completes the grass root removal operation, which can improve the weeding effect.

[0009] Further, first docking gears are installed at both ends of the middle part, and each of the first docking gears is meshed with the first gears located at both ends of the middle part; when the mechanism base is in a straight line shape, the first gear located at the end of the side part is meshed with the first docking gear;

[0010] The side of the middle part has two lateral openings, and each of the side parts has a second docking gear extending out of the shell; when the mechanism base is in a folded form, the second docking gear extends into the lateral opening to engage with one of the first gears in the mechanism base.

[0011] Furthermore, a first transition gear is provided between two adjacent first gears in the middle portion; a second transition gear is provided between two adjacent first gears in the middle portion, and the second docking gear is meshed with the second transition gear.

[0012] In actual use, a cover plate can be set for the docking mechanism part of the middle part and the side part. When the docking mechanism is not needed, the cover plates are installed at the corresponding opening positions on the middle part and the side part 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 portion has a third connecting ear and a fourth connecting ear;

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

[0015] In this way, both the middle part and the side part can be easily disassembled and fixed.

[0016] Furthermore, the side portion is provided with a rotating shaft portion; and the middle portion is fixed with a hinged ear that is rotatably matched with the rotating shaft portion.

[0017] Furthermore, the mowing mechanism includes a mowing assembly installed on the rotating shaft; the mowing assembly includes three types: a flinging blade mechanism, a milling and twisting mechanism, and a flexible strip mechanism. When in use, a suitable mowing blade assembly or a combination of mowing blade assemblies is selected according to the type of grass and the nature of the operation. The flinging blade mechanism and the flexible strip mechanism are generally used to remove or trim the grass on the surface. The flinging blade mechanism is suitable for weeding operations of hard weeds, and the flexible strip mechanism is suitable for; the milling and twisting mechanism can twist 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 folded state, the front rotating shaft is installed with a knife-flipping mechanism or a flexible strip mechanism, and the rear rotating shaft is installed with a milling mechanism. In this way, the front and rear cutting knife mechanisms each perform their respective functions, and the weeding effect is good.

[0019] Furthermore, the blade-flinging mechanism includes a centrally disposed first blade disc and a plurality of hard blades rotatably mounted relative to the first blade disc.

[0020] Furthermore, the milling and cutting mechanism comprises a tool holder and a plurality of milling and cutting blades fixed on the tool holder; the tool bodies of the milling and cutting blades are arranged vertically.

[0021] Furthermore, the flexible strip mechanism includes a second cutter disc and a plurality of rubber strips whose ends are fixed on the second cutter disc.

[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 body; the adjustment mechanism includes an outer sleeve fixed relative to the mechanism base body, and a sliding body and a pressure plate that can slide relative to it are installed in the outer sleeve, and the pressure plate is placed above the sliding body, and a spring is arranged between the two; a disk 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, and a sliding key is arranged between the two, and the sliding body includes an upper chuck and a lower chuck; the disk body is placed between the upper chuck and the lower chuck; the lower chuck can be adjusted up and down and fixed relative to the outer sleeve, specifically, the outer sleeve has a plurality of adjustment holes, and the screws passing through the adjustment holes fix the lower chuck relative to the outer sleeve; the upper chuck can be fixed relative to the lower chuck, and can also be detached from the upper chuck; an adjustment knob that acts on the disk body is installed on the top of the outer sleeve.

[0024] By adopting the above adjustment mechanism, the working mode of the cutter mechanism can be changed as needed. When the upper chuck is fixed relative to the lower chuck, and the lower chuck is fixed relative to the outer sleeve, the height of the cutter mechanism is fixed and does not affect the rotation of the shaft. When the upper chuck is separated from the lower chuck, the lower chuck is fixed relative to the outer sleeve. At this time, the shaft can float up and down elastically, and the initial height of the shaft can be changed by adjusting the position of the lower chuck, and the stiffness of the spring can be changed by adjusting the position of the disc body.

[0025] Beneficial effects: The multi-use 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 the adaptability is strong.

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

[0028] (3) It is possible to select a suitable cutter assembly or a combination of cutter assemblies according to the type of grass and the nature of the operation, and adjust the height of the cutter assembly to improve the operation quality. BRIEF DESCRIPTION OF THE DRAWINGS

When in use, a suitable mowing blade assembly or a combination of mowing blade assemblies is selected according to the type of grass and the nature of the operation. The flinging blade mechanism 22 and the flexible strip mechanism 24 are generally used to remove or trim grass on the surface. The flinging blade mechanism 22 is suitable for weeding operations of hard weeds, and the flexible strip mechanism 24 is suitable for weeding; the milling and twisting mechanism 23 can twist the soil and remove the roots of the grass.
