Description
Grass-moving components and grass-working equipment
[0001] This application claims priority to the Chinese patent applications filed with the Patent Office of China on January 12, 2024, with application numbers CN202420092271.3, CN202420089797.6, and CN202420091522.6, respectively, and with invention names “Grass-mowing single-cylinder assembly, grass-mowing device and lawn working equipment”, “Grass-mowing single-cylinder assembly and lawn working equipment”, and “Grass-mowing assembly and lawn working equipment”, the entire contents of which are incorporated into this application by reference. Technical Field
[0002] The present application relates to the field of lawn cleaning, and in particular to a lawn mowing component and lawn operation equipment. Background Art
[0003] With the development of technology, the types and functions of robots are increasing. Robots are increasingly being used to replace manual labor in lawns in parks, green belts, factory lawns, golf courses, orchards, and other places. For example, lawn mowers, robotic mowers, and other lawn-use equipment are used to clean up fallen leaves, weeds, cut grass, and other debris from lawns.
[0004] In the related art, lawn working equipment is provided with a grass-raising component to raise and roll up fallen leaves, weeds and other debris on the lawn, so as to finally collect them into a collection bin of the lawn working equipment. However, the grass-raising component cannot handle weeds, fallen leaves and other debris at different heights, resulting in low grass-raising efficiency.
[0005] Application Contents
[0006] The first purpose of the present application is to provide a grass-moving component, which aims to solve the technical problem that the existing grass-moving component cannot handle weeds, fallen leaves and other debris at different heights.
[0007] To achieve the above objectives, the solution provided by this application is:
[0008] A grass-lifting assembly comprises a plurality of grass-lifting single-tube assemblies;
[0009] Each of the grass-moving single-tube assemblies includes a mounting body and a plurality of grass-moving units, wherein the plurality of grass-moving units are provided on the mounting body and are spaced apart along the circumferential direction of the mounting body;
[0010] The two adjacent grass-lifting single-tube assemblies are staggered.
[0011] The second purpose of the present application is to provide a lawn working equipment, which includes an equipment body, a power mechanism and the above-mentioned grass-mowing component; the power mechanism is installed on the equipment body and drives the grass-mowing component to drive the grass-mowing component to rotate around a set center to clean the grass.
[0012] The grass-lifting component provided by this application has the following beneficial effects:
[0013] In this embodiment, the grass-mowing assembly includes multiple grass-mowing single-cylinder assemblies, each of which includes a mounting body and multiple grass-mowing units. The multiple grass-mowing units are disposed on the mounting body and spaced apart along the circumference of the mounting body, thereby improving grass-mowing efficiency to a certain extent. The grass-mowing units can lift and roll up weeds, fallen leaves, and other debris on the grass. Importantly, two adjacent grass-mowing single-cylinder assemblies are staggered, so that the grass-mowing units on the two adjacent grass-mowing single-cylinder assemblies have different active diameters when simultaneously contacting the grass. Consequently, when the grass-mowing units of the two adjacent grass-mowing single-cylinder assemblies simultaneously contact the grass, weeds, grass clippings, and other debris at different heights can be processed separately, thereby improving the efficiency of the grass-mowing assembly in rolling up weeds, fallen leaves, and other debris on the grass.

[0028] 1 to 8 , an embodiment of the present application provides a grass-raising assembly 10 that can be installed on lawn working equipment such as a lawn mower, a weeder, or a grass collector to clean up weeds, grass clippings, fallen leaves, and other debris on the lawn. Specifically, the grass-raising assembly 10 of the embodiment of the present application can roll up weeds, grass clippings, fallen leaves, and other debris on the lawn.
[0029] 1 and 2 , the grass-moving assembly 10 provided in the embodiment of the present application includes a plurality of grass-moving single-cylinder assemblies 200, each of which includes a mounting body 210 and a plurality of grass-moving units 220. The plurality of grass-moving units 220 are arranged on the mounting body 210 and are spaced apart along the circumferential direction of the mounting body 210; two adjacent grass-moving single-cylinder assemblies 200 are staggered.
[0030] In this embodiment, the grass-mowing assembly 10 includes multiple grass-mowing mono-cylinder assemblies 200. Each grass-mowing mono-cylinder assembly 200 includes a mounting body 210 and multiple grass-mowing units 220. The multiple grass-mowing units 220 are mounted on the mounting body 210 and spaced apart along the circumference of the mounting body 210, thereby improving grass-mowing efficiency. The grass-mowing units 220 can lift and roll up weeds, fallen leaves, and other debris on the grass. It should be noted that two adjacent grass-mowing mono-cylinder assemblies 200 are staggered, so that the grass-mowing units 220 on the two adjacent grass-mowing mono-cylinder assemblies 200 have different active diameters when simultaneously contacting the grass. Consequently, when the grass-mowing units 220 of the two adjacent grass-mowing mono-cylinder assemblies 200 simultaneously contact the grass, they can respectively handle weeds, grass clippings, and other debris at different heights, thereby improving the efficiency of the grass-mowing assembly 10 in rolling up weeds, fallen leaves, and other debris on the grass.
[0031] Based on the above, some embodiments of the present application will be further described below in conjunction with Figures 1 to 8. In the absence of conflict, the following embodiments and features therein may be combined with each other.
[0032] The first set of embodiments:
[0033] The grass-moving assembly 10 of this embodiment can be seen in FIG. 1 to FIG. 8 .
[0034] 1 and 2 , the grass-moving assembly 10 includes at least one connecting cover 100 and a plurality of grass-moving single-tube assemblies 200 . A connecting cover 100 is provided between two adjacent grass-moving single-tube assemblies 200 , and two adjacent grass-moving single-tube assemblies 200 are respectively connected to the two side surfaces of the connecting cover 100 .
[0035] In this embodiment, the grass-mowing assembly 10 is provided with a connecting cover 100 to connect two adjacent grass-mowing single-tube assemblies 200, which can improve the assembly stability of the multiple grass-mowing single-tube assemblies 200 connected together.
[0036] Referring to Figures 2, 3, and 4, each connecting cover 100 includes a cover plate 110 and two identically structured first connecting portions 120. The two first connecting portions 120 are fixedly connected to opposite side surfaces of the cover plate 110. One first connecting portion 120 is offset relative to the other first connecting portion 120 about the axis of the cover plate 110 (i.e., dotted line i shown in Figure 2 ). This allows the two first connecting portions 120 to be staggered, which helps reduce mold opening difficulty and manufacturing costs during manufacturing. Furthermore, the identical structure of the two first connecting portions 120 simplifies the structure of the connecting cover 100. Two adjacent grass-moving single-tube assemblies 200 are respectively connected to the two first connecting portions 120 of the connecting cover 100, thereby achieving positional offset of the adjacent two grass-moving single-tube assemblies 200 in the axial direction of the connecting cover 100.
[0037] Among them, one of the two first connection parts 120 is offset around the axial center line of the cover plate 110 relative to the other first connection part 120. It can be understood that when the position of one of the first connection parts 120 is set unchanged, the other first connection part 120 is rotated a certain angle with the axial center line of the cover plate 110 as the center, the orthographic projections of the two first connection parts 120 in the axial direction of the cover plate 110 coincide.
[0038] Referring to Figures 2, 4, and 5, and in conjunction with Figures 7 and 8, the mounting body 210 of each grass-moving single-tube assembly 200 includes a mounting plate 211 and two identically structured second connecting portions 212. The two second connecting portions 212 are fixedly connected to opposite sides of the mounting plate 211, respectively. This helps reduce mold opening difficulty and manufacturing costs during manufacturing. Furthermore, the identical structure of the two second connecting portions 212 simplifies the structure of the mounting body 210. One of the two second connecting portions 212 is offset relative to the other second connecting portion 212 about the axis of the mounting plate 211 (i.e., dotted line i shown in Figure 7), so that the two second connecting portions 212 are misaligned. Among the two adjacent grass-moving single-cylinder assemblies 200, the second connection part 212 of one grass-moving single-cylinder assembly 200 is connected to one of the first connection parts 120 of the connecting cover body 100, and the second connection part 212 of the other grass-moving single-cylinder assembly 200 is connected to the other first connection part 120 of the connecting cover body 100, so that the two adjacent grass-moving single-cylinder assemblies 200 are respectively connected to the two first connection parts 120 of the connecting cover body 100. In this embodiment, the installation body 210 of the grass-mowing single-cylinder assembly 200 adopts the same structure as the connecting cover body 100, and only differs in dimensions such as thickness in the axial direction, which makes it convenient to assemble multiple grass-mowing single-cylinder assemblies 200 using the connecting cover body 100. Moreover, when assembling multiple grass-mowing single-cylinder assemblies 200 along the same axial center line, it is only necessary to determine the installation position of the first grass-mowing single-cylinder assembly 200, and the installation positions of subsequent connecting covers 100 and grass-mowing single-cylinder assemblies 200 can also be determined, which effectively reduces the assembly difficulty when assembling multiple grass-mowing single-cylinder assemblies 200, avoids installation errors, and effectively improves installation efficiency.
[0039] Among them, two first connecting parts 120 are integrally formed and connected to the axial two side surfaces of the cover plate 110, and two second connecting parts 212 are integrally formed and connected to the axial two side surfaces of the mounting plate body 211, which can reduce the difficulty of installing the grass-moving single-tube assembly 200 and the connecting cover body 100, and can also simplify the manufacturing process during manufacturing and reduce manufacturing costs.
[0040] It should be noted that the axis line of the cover plate 110 can be understood as a straight line around which the cover plate 110 rotates, and the axis line of the mounting plate body 211 can be understood as a straight line around which the mounting plate body 211 rotates. The cover plate 110 and the mounting plate body 211 both rotate around the same straight line, and the dotted line i shown as an example in Figure 2 and the dotted line i shown as an example in Figure 7 are the same straight line.
[0041] With reference to Figures 4, 5, and 7, in one embodiment, each first connecting portion 120 is provided with a first connecting slot 121, the axis of which is aligned with the axis of the cover plate 110. Each second connecting portion 212 is provided with a second connecting slot 2121, the axis of which is aligned with the axis of the mounting plate 211. When two adjacent grass-moving single-tube assemblies 200 are assembled on the same connecting cover 100, the second connecting slot 2121 covers the first connecting slot 121, thereby connecting the first connecting portion 120 and the second connecting portion 212.
[0042] 3 to 8, in the axial direction of the cover plate 110, the cover plate 110 is provided with a plurality of first positioning portions 111 on both opposite sides, and the plurality of first positioning portions 111 on the same side are arranged at intervals along the circumferential direction of the first connecting portion 120; the adjacent two first positioning portions 111 on the opposite sides of the cover plate 110 are staggered along the circumference of the cover plate 110; in the axial direction of the mounting plate body 211 (i.e., the X direction in FIG7), the mounting plate body 211 is provided with a plurality of second positioning portions 2111 on both opposite sides, and the plurality of second positioning portions 2111 on the same side are arranged at intervals along the circumferential direction of the second connecting portion 212; the adjacent two second positioning portions 111 on the opposite sides of the mounting plate body 211 are staggered along the circumference of the second connecting portion 212. The positioning portions 2111 are staggered along the circumference of the mounting plate 211; the axial center line of the cover plate 110 is the same as the axial center line of the mounting plate 211, and the first positioning portion 111 located on the cover plate 110 and the second positioning portion 2111 located on the mounting plate 211 correspond one to one; in two adjacent grass-mowing single-cylinder assemblies 200, the multiple second positioning portions 2111 located on the same side of one of the grass-mowing single-cylinder assemblies 200 are connected one to one to the multiple first positioning portions 111 on one side of the connecting cover body 100, and the multiple second positioning portions 2111 located on the same side of the other grass-mowing single-cylinder assembly 200 are connected one to one to the multiple first positioning portions 111 on the other side of the connecting cover body 100.
[0043] In this embodiment, multiple first positioning portions 111 are provided on opposite axial sides of the cover plate 110, and multiple first positioning portions 111 are also provided on opposite axial sides of the mounting plate 211. The axis of the cover plate 110 is aligned with the axis of the mounting plate 211, and the cover plate 110 and the mounting plate 211 rotate about the same straight line. The first positioning portions 111 on the cover plate 110 correspond one-to-one with the second positioning portions 2111 on the mounting plate 211. When two adjacent grass-moving single-tube assemblies 200 are assembled into the same connecting cover 100, the multiple second positioning portions 2111 on the same side of one grass-moving single-tube assembly 200 can be aligned and installed one-to-one with the multiple first positioning portions 111 on one side of the connecting cover 100. The multiple second positioning portions 2111 on the same side of the other grass-moving single-tube assembly 200 can then be aligned and installed one-to-one with the multiple first positioning portions 111 on the other side of the connecting cover 100. This improves assembly accuracy and reduces assembly difficulty. The mounting plate body 211 is an arc-shaped mounting plate, the first positioning portion 111 is a first positioning column, and the second positioning portion 2111 is a second positioning column.
[0044] 4 to 6 , each second positioning portion 2111 is provided with a positioning hole 21111 for the corresponding first positioning portion 111 to extend into. The first positioning portion 111 extending into the positioning hole 21111 and the inner wall of the positioning hole 21111 squeeze each other, thereby improving the connection stability between the first connection portion 120 and the second connection portion 212 .
[0045] In a specific embodiment, the inner diameter of the positioning hole 21111 is slightly larger than the outer diameter of the first positioning portion 111 extending therein, so that when the first positioning portion 111 extends into the positioning hole 21111, opposite forces are generated between the outer wall of the first positioning portion 111 and the side wall of the positioning hole 21111, causing the two to squeeze each other, thereby improving the connection firmness between the first positioning portion 111 and the positioning hole 21111, and improving the connection tightness between the grass-mowing single-tube assembly 200 and the connecting cover body 100, thereby making the grass-mowing single-tube assembly 200 firmly installed on the connecting cover body 100.
[0046] 3 and 4 , the outer peripheral wall of each first connection portion 120 is provided with a plurality of first movable grooves 122. The plurality of first movable grooves 122 correspond one-to-one to the plurality of first positioning portions 111. The first movable grooves 122 accommodate the first positioning portions 111, rationally utilizing the space around the first connection portion 120 and improving the structural compactness of the connection cover body 100. The plurality of first movable grooves 122 correspond one-to-one to the plurality of first positioning portions 111. It can be understood that the plurality of first movable grooves 122 on the same side are spaced apart along the circumference of the first connection portion 120. Of the two first movable grooves 122 adjacent to each other in the axial direction of the cover plate 110, one of the first movable grooves 122 is offset relative to the other first movable groove 122 around the axis of the cover plate 110, so that the two adjacent first movable grooves 122 located on both sides of the axial direction of the cover plate 110 are also offset along the circumference of the cover plate 110. It should be understood that the circumference of the cover plate 110 is parallel to the circumference of the first connection portion 120.
[0047] 5 to 8 , the outer peripheral wall of each second connecting portion 212 is provided with a plurality of second movable grooves 2122. The plurality of second movable grooves 2122 correspond one-to-one with the plurality of second positioning portions 2111. The second movable grooves 2122 accommodate the second positioning portions 2111, effectively utilizing the space surrounding the second connecting portion 212 and improving the structural compactness of the mounting body 210. The plurality of second movable grooves 2122 correspond one-to-one with the plurality of second positioning portions 2111. Thus, the plurality of second movable grooves 2122 on the same side are spaced apart along the circumference of the second connecting portion 212. Of two adjacent second movable grooves 2122 along the axial direction of the mounting plate 211, one second movable groove 2122 is offset relative to the other second movable groove 2122 about the axis of the mounting plate 211, such that the adjacent second movable grooves 2122 located on either side of the mounting plate 211 are also offset along the circumference of the mounting plate 211. It should be understood that the circumference of the mounting plate 211 is parallel to the circumference of the second connecting portion 212.
[0048] 2, 5, and 6, each grass-moving unit 220 includes two grass-moving members 221. The two grass-moving members 221 of each grass-moving unit 220 are located on opposite sides of the mounting plate 211 along the axial direction of the mounting plate 211. The two grass-moving members 221 of each grass-moving unit 220 are staggered along the circumference of the mounting plate 211. The multiple grass-moving members 221 correspond one-to-one with the multiple second positioning portions 2111. In this way, the staggered grass-moving members 221 are at different heights above the ground. Thus, the adjacent two grass-moving members 221 located on either side of the mounting plate 211 can respectively remove weeds or grass clippings at different heights above the ground, thereby improving grass-moving efficiency and accuracy. The grass-moving members 221 are rotatably connected to the second positioning portion 2111. The grass-moving members 221 are configured to rotate about the second positioning portion 2111 under the action of an appropriate external force and stop rotating when they abut against the outer wall of the second connecting portion 212. It can be understood that the force that drives the grass-lifting piece 221 to rotate and press against the outer wall of the second connecting part 212 is an appropriate external force. When the grass-lifting piece 221 is rotated by the appropriate external force, it presses against the outer wall of the second connecting part 212 and stops rotating. At this time, the outer wall of the second connecting part 212 can provide support for the grass-lifting piece 221, thereby preventing the grass-lifting piece 221 from sinking into the grass.
[0049] 4 and 5 , in a specific embodiment, the grass-lifting piece 221 can rotate within the circumferential range surrounded by the first movable groove 122 and the second movable groove 2122 under the action of external force, and the first movable groove 122 and the second movable groove 2122 are both arc-shaped grooves. In this way, when the grass-lifting piece 221 abuts against the outer wall of the second connecting portion 212, the direction of the supporting force exerted on the grass-lifting piece 221 by the outer wall of the second connecting portion 212 is tangent to the outer peripheral surface of the mounting plate body 211 and is opposite to the direction of the resistance encountered by the grass-lifting piece 221, thereby improving the supporting effect on the grass-lifting piece 221 and effectively preventing the grass-lifting piece 221 from sinking into the grass.
[0050] In one embodiment, the grass lifting member 221 is a torsion spring. The torsion spring has a certain elasticity, which increases the difficulty of damaging the grass lifting member 221, so that the grass lifting member 221 is not easily damaged during the process of rolling up the weeds.
[0051] 2 , 4 and 5 , in a specific embodiment, three groups of grass-moving units 220 are provided on the same grass-moving single-tube assembly 200, and each group of grass-moving units 220 is provided with two grass-moving members 221. Three second positioning portions 2111 are provided on the same side, and three second movable grooves 2122 are also provided on the same side. Correspondingly, in the same connecting cover body 100, three first positioning portions 111 are provided on the same side, and three first movable grooves 122 are also provided on the same side, so as to simplify the structure of the grass-moving single-tube assembly 200 and the connecting cover body 100.
[0052] Referring to Figures 1, 2, and 4, and in conjunction with Figures 7 and 8, the grass-moving assembly 10 further includes a connecting post 300. Each connecting cover 100 is provided with a first mounting hole 130 along its axis, and each mounting body 210 is provided with a second mounting hole 213 along its axis. The second mounting holes 213 of two adjacent grass-moving mono-tube assemblies 200 are located on either side of the first mounting hole 130 of the connecting cover 100, and the first mounting holes 130 and the second mounting holes 213 are connected to form a through hole for the connecting post 300 to pass through, thereby securely mounting the multiple grass-moving mono-tube assemblies 200 and the connecting cover 100 on the connecting post 300. It should be understood that the axis of the mounting body 210 is the same as the axis of the connecting cover 100, and the mounting body 210 and the connecting cover 100 both rotate about the same straight line.
[0053] In one embodiment, the inner wall surface of the through hole is provided with a plurality of limiting grooves 400, and the plurality of limiting grooves 400 are evenly arranged along the circumference of the through hole. When the connecting column 300 passes through the through hole, the outer wall surface of the connecting column 300 can be embedded in part or all of the plurality of limiting grooves 400 to adjust the position of the outer wall surface of the connecting column 300 embedded in the inner wall surface of the through hole in the circumferential direction of the through hole, so that the grass-moving single-tube assembly 200 and the connecting cover body 100 can be installed on the connecting column 300 at different angles to meet different needs.
[0054] With reference to Figures 1, 4, and 8, in one specific embodiment, the connecting post 300 is in the shape of a quadrangular prism. When the connecting post 300 passes through the through-hole, the four circumferential corners of the connecting post 300 can be respectively inserted into any one of the limiting grooves 400. Rotating the connecting post 300 allows the four corners of the connecting post 300 to be respectively inserted into four of the plurality of limiting grooves 400, thereby adjusting the position of the outer wall of the connecting post 300 inserted into the inner wall of the through-hole, thereby adjusting the angle at which the grass-moving single-tube assembly 200 and the connecting cover 100 are installed on the connecting post 300. Exemplarily, twelve limiting grooves 400 are provided.
[0055] In one embodiment, four retaining grooves 400 are provided, and the outer wall of the connecting post 300 is provided with multiple raised portions, evenly spaced along the circumference of the connecting post 300. When the through hole is formed, four of the raised portions of the connecting post 300 engage with the four retaining grooves 400, respectively, allowing the position of the outer wall of the connecting post 300 to be adjusted relative to the inner wall of the through hole, thereby adjusting the angle at which the grass-moving single-tube assembly 200 and the connecting cover 100 are mounted on the connecting post 300. For example, twelve raised portions are provided.
[0056] 4 and 8 , in one embodiment, each first connection portion 120 includes a plurality of first cylinders 123 surrounding the first mounting hole 130. The plurality of first cylinders 123 correspond one-to-one to the plurality of first movable grooves 122. Two adjacent first cylinders 123 are connected and, together with the mounting plate 211, form a first movable groove 122. Each second connection portion 212 includes a plurality of second cylinders 2123 surrounding the second mounting hole 213. The plurality of second cylinders 2123 correspond one-to-one to the plurality of second movable grooves 2122. Two adjacent second cylinders 2123 are connected and, together with the mounting plate 211, form a second movable groove 2122.
[0057] In conjunction with Figures 1 and 2 , in one embodiment, the grass-moving assembly 10 further includes two connecting end caps 500 disposed at each end of the plurality of grass-moving mono-tube assemblies 200. The connecting end caps 500 are also passed through and secured by the connecting post 300. The two connecting end caps 500 are respectively secured to the first and last grass-moving mono-tube assemblies 200. The connecting end caps 500 can be designed as a single-side connection to the cover body 100 to simplify the structure.
[0058] In conjunction with Figure 1, an embodiment of the present application also provides a lawn working device (not shown), including an equipment body (not shown), a power mechanism (not shown) and the above-mentioned grass-mowing component 10; the power mechanism is installed on the equipment body and drives the grass-mowing component 10 to drive the grass-mowing component 10 to rotate around a set center to clean the grass.
[0059] In this embodiment, the lawn work device utilizes the aforementioned mowing assembly 10 and is provided with a power mechanism to drive the mowing assembly 10 to rotate, so that the mowing unit 220 of the mowing assembly 10 can roll up weeds, fallen leaves, and other debris on the lawn. Furthermore, the lawn work device, utilizing the mowing assembly 10, can handle weeds, grass clippings, and other debris at different heights.
[0060] The second set of embodiments:
[0061] The grass-lifting assembly 10 of this embodiment can be seen in Figures 2 and 5 to 8 .
[0062] 2 and 5 , in the grass-mowing assembly 10 of the embodiment of the present application, each grass-mowing single-tube assembly 200 includes a mounting body 210 and a plurality of grass-mowing units 220 disposed on the mounting body 210 , and the plurality of grass-mowing units 220 are spaced apart along the circumferential direction of the mounting body 210 .
[0063] Furthermore, each grass-lifting unit includes a plurality of grass-lifting pieces 221, which are spaced apart around the circumference of the mounting body 210. In conjunction with FIG7 , the mounting body 210 is provided with a second mounting hole 213 along its axial center line (i.e., the dotted line i exemplarily shown in FIG7 ) for the external connecting column 300 to pass through; the inner circumferential surface of the second mounting hole 213 is provided with a plurality of limiting grooves 400 arranged along the circumferential direction of the second mounting hole 213, and at least a portion of the limiting grooves 400 is used for the outer circumferential surface of the external connecting column 300 to be embedded and fixed.
[0064] In this embodiment, the grass-moving mono-cylinder assembly 200 includes a mounting body 210 and a plurality of grass-moving elements 221 disposed on the mounting body 210. The grass-moving elements 221 are used to remove weeds, grass clippings, fallen leaves, and other debris from the grass. The grass-moving elements 221 are spaced apart around the periphery of the mounting body 210, thereby improving the efficiency of the grass-moving mono-cylinder assembly 200 in picking up weeds, grass clippings, fallen leaves, and other debris. Furthermore, the mounting body 210 has a second mounting hole 213 formed along its axis for the external connecting post 300 to pass through. This facilitates mounting the grass-moving mono-cylinder assembly 200 on the external connecting post 300 and reduces installation difficulty. In this embodiment, the external connecting post 300 is not part of the grass-moving mono-cylinder assembly 200. It should be understood that any component that is provided with the second mounting hole 213 for mounting the grass-moving mono-cylinder assembly 200, such as a rotating shaft driven by an external power mechanism, can be considered the external connecting post 300.
[0065] In this embodiment, the inner circumferential surface of the second mounting hole 213 is provided with a plurality of retaining grooves 400 arranged along the circumference of the second mounting hole 213. At least a portion of the retaining grooves 400 is configured to receive and secure the outer circumferential surface of the external connecting post 300. It will be appreciated that when the grass-moving monotube assembly 200 is mounted on the external connecting post 300, the outer wall of the external connecting post 300 can be inserted into some or all of the plurality of retaining grooves 400, thereby adjusting the position of the outer wall of the external connecting post 300 within the inner wall of the second mounting hole 213 along the circumferential direction of the second mounting hole 213. This allows the mounting body 210 to be mounted on the external connecting post 300 at various angles to meet varying installation requirements.
[0066] The grass lifting element 221 can lift and roll up weeds, fallen leaves and other debris on the grass.
[0067] It should be understood that the mounting body 210 is provided with a second mounting hole 213 along its axis for the external connecting column 300 to pass through, which means that the axis of the mounting body 210 is the same as the axis of the second mounting hole 213. The axis of the mounting body can be understood as a straight line around which the mounting body 210 rotates.
[0068] 5 and 7 , the mounting body 210 includes a mounting plate body 211 and a second connecting portion 212. The second connecting portion 212 is connected to the mounting plate body 211. A second mounting hole 213 is formed at the center of the mounting plate body 211 and the center of the second connecting portion 212. A plurality of grass-lifting pieces 221 are arranged on the mounting plate body 211 at intervals around the circumference of the second mounting hole 213. The plurality of grass-lifting pieces 221 and the second connecting portion 212 are located on the same axial side of the mounting plate body 211.
[0069] In this embodiment, the mounting body 210 includes a mounting plate 211 and a second connecting portion 212. The second connecting portion 212 is connected to the mounting plate 211. A plurality of grass-moving elements 221 are spaced apart on the mounting plate 211 around the circumference of the second mounting hole 213. The plurality of grass-moving elements 221 and the second connecting portion 212 are located axially on the same side of the mounting plate 211, simplifying the construction of the grass-moving single-tube assembly 200. The second mounting hole 213 is formed at the center of the mounting plate 211 and the center of the second connecting portion 212. It is understood that two openings are respectively defined at the center of the mounting plate 211 and the center of the second connecting portion 212, and the two openings are axially connected to form the second mounting hole 213. The mounting plate 211 and the second connecting portion 212 share the same axis. This structure helps to reduce mold making difficulty and manufacturing costs. The mounting plate 211 is an annular mounting plate.
[0070] 5 and 7 , three grass-lifting members 221 are provided on the same side, and two adjacent grass-lifting members 221 are provided at an angle of 120° with the axis of the second mounting hole 213 as the center. This reasonable arrangement can not only simplify the structure of the grass-lifting single-tube assembly 200, but also improve the efficiency of rolling up weeds, fallen leaves, grass clippings and other debris on the grass.
[0071] 5 and 7 , the mounting plate body 211 is provided with a plurality of second positioning portions 2111 spaced apart around the circumference of the second mounting hole 213 . The plurality of second positioning portions 2111 and the plurality of grass-lifting pieces 221 are located on the same axial side of the mounting plate body 211 . The plurality of grass-lifting pieces 221 correspond one-to-one to the plurality of second positioning portions 2111 , and the grass-lifting pieces 221 are connected to the second positioning portions 2111 .
[0072] In this embodiment, with reference to FIG7 , in the axial direction of the second mounting hole 213, adjacent second positioning portions 2111 of the plurality of second positioning portions 2111 located on the same side as the grass-lifting member 221 are also arranged at a 120° angle to each other. This ensures that, in the plurality of grass-lifting members 221 mounted on the plurality of second positioning portions 2111, adjacent grass-lifting members 221 located on the same side of the second mounting hole 213 are arranged at a 120° angle with the axis of the second mounting hole 213 as the center. In this embodiment, the grass-lifting member 221 is connected to the second positioning portion 2111. It should be understood that the grass-lifting member 221 may be fixedly connected to the second positioning portion 2111 or rotatably connected to the second positioning portion 2111, and the specific arrangement is not limited in this embodiment.
[0073] 5 and 7 , in a specific embodiment, the second positioning portion 2111 is a positioning column, and each second positioning portion 2111 extends along the axial direction of the second mounting hole 213, thereby simplifying the structure of the second positioning portion 2111. Moreover, the grass-lifting piece 221 can be installed on the outer peripheral side of the positioning column along the axial direction of the second mounting hole 213, thereby simplifying the connection between the grass-lifting piece 221 and the second positioning portion 2111.
[0074] 5, 6 and 7, two second connection parts 212 are provided, and the two second connection parts 212 have the same structure. In the axial direction of the second mounting hole 213 (i.e., the X direction in FIG7), the two second connection parts 212 are respectively connected to the opposite side surfaces of the mounting plate body 211; a plurality of second positioning parts 2111 are provided on both axial side surfaces of the mounting plate body 211, and the plurality of second positioning parts 2111 on the same side are spaced apart around the circumference of the second mounting hole 213; a plurality of grass-lifting pieces 221 and a plurality of second positioning parts 2111 correspond one to one, and the grass-lifting pieces 221 are connected to the second positioning parts 2111.
[0075] In this embodiment, two second connecting portions 212 are provided, and both second connecting portions 212 have the same structure, which helps save manufacturing steps and reduce manufacturing costs. The two second connecting portions 212 are respectively connected to opposite sides of the mounting plate 211. A plurality of second positioning portions 2111 are provided on both axial sides of the mounting plate 211. The plurality of grass-lifting elements 221 correspond one-to-one with the plurality of second positioning portions 2111. The plurality of grass-lifting elements 221 located on both sides of the mounting plate 211 can simultaneously clean the grass, helping to improve the efficiency of the grass-lifting single-tube assembly 200 in picking up weeds, grass clippings, and other debris.
[0076] It should be understood that as an implementation of an embodiment of the present application, the mounting body 210 of the grass-mowing single-cylinder assembly 200 may include a mounting plate body 211 and a second connecting portion 212 arranged on one side of the mounting plate body 211, and multiple second positioning portions 2111, multiple grass-mowing pieces 221 and the second connecting portion 212 are all located on the same side, and multiple grass-mowing pieces 221 are respectively installed on multiple second positioning portions 2111 in a one-to-one correspondence, which can improve the efficiency of the grass-mowing single-cylinder assembly 200 in rolling up weeds and other debris to a certain extent. As another implementation of the embodiment of the present application, the mounting body 210 of the grass-mowing single-cylinder assembly 200 may include a mounting plate body 211 and two second connecting parts 212, that is, second connecting parts 212 are arranged on both sides of the mounting plate body 211, and correspondingly, multiple second positioning parts 2111 and multiple grass-mowing parts 221 are arranged on both sides of the mounting plate body 211, and the multiple grass-mowing parts 221 are respectively installed on the multiple second positioning parts 2111 in a one-to-one correspondence, which can further improve the efficiency of the grass-mowing single-cylinder assembly 200 in rolling up weeds and other debris.
[0077] Referring to Figures 5 and 7 , two second connecting portions 212 are provided on opposite sides of the mounting plate 211 along the axial direction of the second mounting hole 213. One of the second connecting portions 212 is offset 30° relative to the other about the axis of the second mounting hole 213. This staggers the two second connecting portions 212, thereby improving the efficiency of weed-collecting by the single-barrel weed-collecting assembly 200. It can be understood that by keeping one of the second connecting portions 212 in position unchanged and rotating the other second connecting portion 212 30° about the axis of the second mounting hole 213, the orthographic projections of the two second connecting portions 212 in the axial direction of the second mounting hole 213 coincide.
[0078] Referring to Figures 5, 7, and 8, in one specific embodiment, the outer peripheral wall of each second connecting portion 212 is provided with three second movable grooves 2122. The three second movable grooves 2122 correspond one-to-one with the three second positioning portions 2111. The second movable grooves 2122 accommodate the second positioning portions 2111. In the axial direction of the second mounting hole 213, one of two adjacent second movable grooves 2122 is offset by 30° relative to the other second movable groove 2122 about the axis of the second mounting hole 213, thereby misaligning the two second movable grooves 2122. In this embodiment, the positions of two adjacent second movable grooves 2122 located on either side of the mounting plate 211 are designed as described above. This allows the three second movable grooves 2122 of each second connecting portion 212 to avoid the three second positioning portions 2111, thereby not affecting the installation of the grass-lifting member 221.
[0079] 8 , in one embodiment, each second connecting portion 212 includes a plurality of second barrels 2123 surrounding the second mounting hole 213. The plurality of second barrels 2123 correspond one-to-one to the plurality of second movable grooves 2122. Two adjacent second barrels 2123 are connected and, together with the mounting plate 211, form a second movable groove 2122. The second barrels 2123 are integrally formed and connected to the mounting plate 211.
[0080] Referring to Figures 5, 7, and 8, two adjacent second positioning portions 2111 on opposite axial side surfaces of the mounting plate 211 are staggered along the circumference of the second mounting hole 213 and are offset by 15° with respect to the axis of the second mounting hole 213. This allows one of the two adjacent grass-lifting members 221 in the axial direction of the second mounting hole 213 to be positioned 15° circumferentially offset with respect to the other grass-lifting member 221 with respect to the axis of the second mounting hole 213. In this manner, the staggered grass-lifting members 221 are positioned at different heights above the ground, allowing the two adjacent grass-lifting members 221 on opposite axial sides of the mounting plate 211 to respectively handle weeds or grass clippings at different heights above the ground, thereby improving grass-lifting efficiency and accuracy.
[0081] 5 and 6 , the grass lifting member 221 is a torsion spring having a certain elasticity, which increases the difficulty of damaging the grass lifting member 221 , so that the grass lifting member 221 is not easily damaged during the process of rolling up the weeds.
[0082] Specifically, the torsion spring includes a main body 2211, a first arm 2212 and a second arm 2213. The main body 2211 is arranged around the second positioning portion 2111, the first arm 2212 is connected to one circumferential side of the main body 2211, and the second arm 2213 is connected to the other circumferential side of the main body 2211. The first arm 2212 and the second arm 2213 can be integrally connected on both sides of the main body 2211. The first arm 2212 can be used to roll up weeds, fallen leaves and other debris.
[0083] 2 , 5 and 7 , in one embodiment, the inner circumferential surface of the second mounting hole 213 is provided with at least four limiting grooves 400 , and the at least four limiting grooves 400 are arranged along the circumferential direction of the second mounting hole 213 ; any one of the at least four limiting grooves 400 is used for any one of the at least four protrusions on the outer circumferential wall of the external connecting column 300 to be embedded, so that the connection position between the outer wall surface of the external connecting column 300 and the inner wall surface of the second mounting hole 213 can be adjusted.
[0084] 2 , 5 , and 7 , in one embodiment, the external connecting post 300 is in the shape of a quadrangular prism. When the external connecting post 300 passes through the second mounting hole 213 , the four circumferential protrusions of the external connecting post 300 can be respectively inserted into any one of the limiting grooves 400 . By rotating the external connecting post 300 , the four protrusions of the external connecting post 300 can be respectively inserted into four of the plurality of limiting grooves 400 , thereby adjusting the position at which the outer wall of the external connecting post 300 is inserted into the inner wall of the second mounting hole 213 , thereby adjusting the angle at which the mounting plate 211 is mounted on the external connecting post 300 . For example, twelve limiting grooves 400 are provided.
[0085] In conjunction with Figures 2, 5, and 7, in one embodiment, four retaining grooves 400 are provided, and the outer wall of the external connecting column 300 is provided with multiple raised portions, which are evenly arranged along the circumference of the external connecting column 300. When the second mounting hole 213 is formed, four of the raised portions of the external connecting column 300 respectively engage with the four retaining grooves 400, allowing the position of the outer wall of the external connecting column 300 to be adjusted relative to the inner wall of the second mounting hole 213, thereby adjusting the angle at which the mounting plate 211 is mounted on the external connecting column 300. For example, twelve raised portions are provided.
[0086] 2 , 5 and 7 , the grass-moving assembly 10 of this embodiment further includes a plurality of connecting cover bodies 100 and a plurality of the above-mentioned grass-moving single-tube assemblies 200. In the axial direction of the second mounting hole 213, a connecting cover body 100 is provided between two adjacent grass-moving single-tube assemblies 200; two adjacent grass-moving single-tube assemblies 200 are respectively connected to the two side surfaces of the connecting cover body 100; in the axial direction of the second mounting hole 213, among the two adjacent connecting cover bodies 100, one connecting cover body 100 is offset relative to the other connecting cover body 100 around the axial center line of the second mounting hole 213 (i.e., the dotted line i exemplarily shown in FIG2 ) so that the two connecting cover bodies 100 are misaligned.
[0087] In this embodiment, the grass-mowing assembly 10 includes multiple grass-mowing mono-cylinder assemblies 200. These multiple grass-mowing mono-cylinder assemblies 200 work together to roll up weeds on the grass, thereby improving the efficiency of the grass-mowing assembly 10. Furthermore, one of the two adjacent connecting covers 100 is offset relative to the other connecting cover 100 about the axis of the second mounting hole 213, so that the two connecting covers 100 are staggered. This results in the two adjacent grass-mowing mono-cylinder assemblies 200 being staggered, resulting in different active diameters when the two adjacent grass-mowing mono-cylinder assemblies 200 contact the grass. Consequently, the two adjacent grass-mowing mono-cylinder assemblies 200 can each process weeds, grass clippings, and other debris at different heights, thereby improving grass-mowing efficiency.
[0088] It should be noted that the dotted line i exemplarily shown in FIG. 2 and the dotted line i exemplarily shown in FIG. 7 are the same straight line, and the grass-moving single-tube assembly 200 , the connecting cover 100 and the external connecting column 300 all rotate around the same straight line.
[0089] Referring to Figure 2 and in conjunction with Figure 7 , the misalignment angle of two adjacent connecting covers 100 about the axis of the second mounting hole 213 is 30°, which can improve the working efficiency of the grass-mowing assembly 10. In one specific embodiment, the mounting body 210 of the grass-mowing mono-tube assembly 200 adopts the same structure as the connecting cover 100, differing only in dimensions such as axial thickness. This facilitates the assembly of multiple grass-mowing mono-tube assemblies 200 using the connecting cover 100. Moreover, when assembling multiple grass-mowing mono-tube assemblies 200 along the same axis, only the installation position of the first grass-mowing mono-tube assembly 200 needs to be determined, and the installation positions of subsequent connecting covers 100 and grass-mowing mono-tube assemblies 200 can also be determined. This effectively reduces the assembly difficulty when assembling multiple grass-mowing mono-tube assemblies 200, avoids installation errors, and effectively improves installation efficiency.
[0090] In combination with Figures 2, 5 and 7, this embodiment also provides a lawn working equipment (not shown), which includes an equipment body (not shown), a power mechanism (not shown), a connecting column 300 and the above-mentioned grass-mowing component 10. The power mechanism is arranged on the equipment body, the connecting column 300 is passed through the second mounting hole 213, and the outer wall surface of the connecting column 300 is embedded in at least a part of the limiting groove 400. The power mechanism drives the connecting column, and the connecting column drives the grass-mowing single-cylinder component 200 to rotate under the drive of the power mechanism to clean the grass.
[0091] In this embodiment, the lawn work equipment utilizes the aforementioned mowing assembly and is provided with a power mechanism to drive the connecting column to rotate, thereby driving the mowing mono-cylinder assembly 200 to rotate. Thus, the mowing element 221 of the mowing mono-cylinder assembly 200 can roll up weeds, fallen leaves, and other debris on the lawn. The use of the mowing mono-cylinder assembly 200 in the lawn work equipment can improve work efficiency.
[0092] The third group of embodiments:
[0093] The grass-moving assembly 10 of this embodiment can be seen in FIG. 2 and FIG. 5 to FIG. 8 .
[0094] 2 , 5 and 7 , in the grass-mowing assembly 10 provided in the embodiment of the present application, each grass-mowing single-tube assembly 200 includes a mounting body 210 and a plurality of grass-mowing units 220 . The plurality of grass-mowing units 220 are arranged on the mounting body 210 and are spaced apart along the circumferential direction of the mounting body 210 .
[0095] Furthermore, the mounting body 210 of each grass-moving single-tube assembly 200 includes a mounting plate body 211 and two second connecting parts 212 of identical structure. The two second connecting parts 212 are respectively connected to the opposite side surfaces of the mounting plate body 211, and one of the second connecting parts 212 is offset relative to the other second connecting part 212 around the axial center line of the mounting plate body 211 (i.e., the dotted line i exemplarily shown in Figure 7) so that the two second connecting parts 212 are staggered.
[0096] In this embodiment, the mounting body 210 of each grass-mowing single-barrel assembly 200 includes a mounting plate 211 and two identically constructed second connecting portions 212. The two second connecting portions 212 are connected to opposite side surfaces of the mounting plate 211, and one of the second connecting portions 212 is offset relative to the other second connecting portion 212 about the axis of the mounting plate 211. This allows for staggered positioning of the two second connecting portions 212, which reduces mold creation complexity and manufacturing costs during manufacturing. Furthermore, the identical structure of the two second connecting portions 212 simplifies the structure of the grass-mowing single-barrel assembly 200. Specifically, one of the two second connecting portions 212 is offset relative to the other second connecting portion 212 about the axis of the mounting plate 211. It is understood that, by setting one of the second connecting portions 212 unchanged and rotating the other second connecting portion 212 by a certain angle about the axis of the mounting plate 211, the orthographic projections of the two second connecting portions 212 in the axial direction of the mounting plate 211 coincide.
[0097] Furthermore, each grass-lifting unit 220 includes a plurality of grass-lifting pieces 221, and a plurality of second positioning portions 2111 are provided on both sides of the mounting plate body 211, and the plurality of second positioning portions 2111 on the same side are arranged along the circumferential direction of the mounting plate body 211; the plurality of grass-lifting pieces 221 correspond one-to-one to the plurality of second positioning portions 2111, and the grass-lifting pieces 221 are rotatably connected to the second positioning portions 2111; the outer peripheral wall of each second connecting portion 212 is provided with a plurality of second movable grooves 2122, and the plurality of second movable grooves 2122 correspond one-to-one to the plurality of second positioning portions 2111, and the second movable grooves 2122 accommodate the second positioning portions 2111.
[0098] In this embodiment, each grass-moving unit 220 includes multiple grass-moving members 221. Multiple second positioning portions 2111 are provided on both sides of the mounting plate 211. Each of the multiple grass-moving members 221 corresponds to each of the multiple second positioning portions 2111. The grass-moving members 221 are rotatably connected to the second positioning portions 2111 and can rotate about the second positioning portions 2111 under the action of an external force. The multiple second positioning portions 2111 on the same side are arranged along the circumference of the mounting plate 211, thereby also arranging the multiple grass-moving members 221 on the same side along the circumference of the mounting plate 211. This can improve the grass-moving efficiency of the grass-moving members 221 to a certain extent. The outer peripheral wall of each second connecting portion 212 is provided with a plurality of second movable grooves 2122. The plurality of second movable grooves 2122 correspond one-to-one with the plurality of second positioning portions 2111. The second movable grooves 2122 receive the second positioning portions 2111, allowing the grass-lifting member 221 to rotate within the range of the second movable grooves 2122. This expands the range of motion of the grass-lifting member 221, increases the range of the grass-lifting member 221 in which it can remove weeds, grass clippings, fallen leaves, and other debris from the lawn, and improves the efficiency of the grass-lifting member 221. Specifically, the grass-lifting member 221 can lift and roll up weeds, fallen leaves, and other debris from the lawn.
[0099] In this embodiment, the above-mentioned positions of the second connecting parts 212 on both sides of the mounting plate 211 are set. When the grass-mowing single-cylinder assembly 200 is applied to lawn working equipment and multiple grass-mowing single-cylinder assemblies 200 are provided, multiple grass-mowing single-cylinder assemblies 200 can be assembled on the lawn working equipment in sequence along the axial direction of the mounting plate 211, thereby reducing the difficulty of assembly.
[0100] In this embodiment, the grass-lifting member 221 is capable of rotating within the range of the second movable groove 2122. It should be understood that, while picking up weeds and other debris, the grass-lifting member 221 is subjected to external force, causing it to rotate about the second positioning portion 2111. The angle of rotation of the grass-lifting member 221 is determined by the magnitude of the external force. Whether the grass-lifting member 221 contacts or even abuts the outer wall of the second connecting portion 212 during rotation is also determined by the magnitude of the external force applied to the grass-lifting member 221. For example, in some cases, while the grass-lifting member 221 is cleaning the grass, the force applied by weeds and other debris can cause the grass-lifting member 221 to rotate and abut against the outer wall of the second connecting portion 212. In this case, the second connecting portion 212 can provide some support for the grass-lifting member 221. In other cases, while cleaning the grass, the force applied by weeds and other debris can cause the grass-lifting member 221 to rotate a certain angle, but not enough to cause the grass-lifting member 221 to contact the outer wall of the second connecting portion 212.
[0101] It should be noted that the axis of the mounting plate 211 can be understood as a straight line around which the mounting plate 211 rotates.
[0102] 5 , 7 and 8 , the two second positioning portions 2111 adjacent along the axial direction of the mounting plate body 211 (i.e., the X direction in FIG7 ) are respectively located on opposite side surfaces of the mounting plate body 211 and are staggered along the circumference of the mounting plate body 211, so that in the axial direction of the mounting plate body 211, the orthographic projections of the two adjacent second positioning portions 2111 do not overlap, so that the positions of the two adjacent grass-lifting members 221 located on both sides of the axial direction of the mounting plate body 211 are also staggered circumferentially. In this way, the staggered grass-lifting members 221 are at different heights from the ground, so that the two adjacent grass-lifting members 221 located on both sides of the mounting plate body 211 can respectively process weeds or grass clippings at different heights from the ground, thereby improving the grass-lifting efficiency and grass-lifting accuracy.
[0103] 5 and 7 , each second positioning portion 2111 is a positioning column, and each second positioning portion 2111 extends along the axial direction of the mounting plate 211 , which can simplify the structure of the second positioning portion 2111 . Moreover, the grass-lifting member 221 is installed on the outer peripheral side of the positioning column and can rotate around the central axis of the positioning column under the action of external force.
[0104] 5 and 8 , the second movable groove 2122 is an arc-shaped groove. In this embodiment, when the grass-lifting member 221 is subjected to an external force, the entire moving trajectory of the grass-lifting member 221 is arc-shaped. Setting the second movable groove 2122 as an arc-shaped groove can expand the range of movement of the grass-lifting member 221 to a certain extent.
[0105] 5, 7, and 8, in the axial direction of the mounting plate body 211, of two adjacent second movable grooves 2122 on opposite side surfaces of the mounting plate body 211, one second movable groove 2122 is offset relative to the other second movable groove 2122 around the axial centerline of the mounting plate body 211, so that the two second movable grooves 2122 are staggered along the circumferential direction of the mounting plate body 211. It will be understood that the two second movable grooves 2122 adjacent to each other along the axial direction of the mounting plate body 211 are respectively located on opposite side surfaces of the mounting plate body 211 and are staggered along the circumferential direction of the mounting plate body 211.
[0106] In this embodiment, the positions of the two adjacent second movable grooves 2122 located on both sides of the axial direction of the mounting plate body 211 adopt the above-mentioned design, so that the movable range of each grass-lifting member 221 can be the same, and the positions of the two adjacent grass-lifting members 221 located on both sides of the mounting plate body 211 in the circumferential direction of the mounting plate body 211 can be staggered, so that the two adjacent grass-lifting members 221 located on both sides of the mounting plate body 211 can handle weeds at different heights from the ground, thereby improving the grass-lifting efficiency.
[0107] Referring to Figures 5 and 8 , three second movable grooves 2122 are provided on the same side. These three second movable grooves 2122 are evenly spaced along the circumference of the second connecting portion 212, creating a rational arrangement that simplifies the structure of the grass-moving mono-tube assembly 200. It will be appreciated that the three second movable grooves 2122 provided on the same side also necessitate three second positioning portions 2111 and three grass-moving members 221, respectively, on the same side.
[0108] 5 and 8 , the grass-lifting member 221 is rotatably mounted on the second positioning portion 2111 , and the grass-lifting member 221 is at least used to rotate around the second positioning portion 2111 within the second movable groove 2122 under appropriate external force, and to stop rotating by abutting the second connecting portion 212 .
[0109] In this embodiment, the grass-lifting member 221 is rotatably mounted on the second positioning portion 2111, simplifying the connection between the grass-lifting member 221 and the second positioning portion 2111. The grass-lifting member 221 is configured to rotate around the second positioning portion 2111 within the second movable groove 2122 and abut against the second connecting portion 212 under the action of an appropriate external force. It is understood that the grass-lifting member 221 can rotate around the second positioning portion 2111 within the second movable groove 2122 under the action of an external force of a certain magnitude, but the external force applied to the grass-lifting member 221 is insufficient to cause the grass-lifting member 221 to rotate to a position where it abuts against the second connecting portion 212. Alternatively, the grass-lifting member 221 can rotate around the second positioning portion 2111 under the action of an appropriate external force until it abuts against the second connecting portion 212, thereby ceasing rotation. The force driving the grass-lifting member 221 to rotate and abut against the second connecting portion 212 is an appropriate external force. The grass-lifting member 221 rotates within the range of the second movable groove 2122, which is provided on the outer circumference of the second connecting portion 212. The abutment between the grass-lifting member 221 and the second connecting portion 212 can also be understood as the abutment between the grass-lifting member 221 and the inner sidewall of the second movable groove 2122. In this embodiment, the grass-lifting member 221, while rotating under the appropriate external force, abuts against the outer sidewall of the second connecting portion 212, stopping rotation. At this time, the outer sidewall of the second connecting portion 212 provides support for the grass-lifting member 221, thereby preventing the grass-lifting member 221 from sinking into the grass.
[0110] In the embodiment where the second movable groove 2122 is an arc-shaped groove, when the grass-lifting piece 221 abuts against the outer wall of the second connecting portion 212, the direction of the force exerted by the outer wall of the second connecting portion 212 on the grass-lifting piece 221 is tangent to the outer peripheral surface of the mounting plate body 211 and is opposite to the direction of the resistance encountered by the grass-lifting piece 221, thereby improving the supporting effect on the grass-lifting piece 221 and effectively preventing the grass-lifting piece 221 from sinking into the grass.
[0111] 5 and 6 , in one embodiment, the grass lifting member 221 is a torsion spring having a certain elasticity, which increases the difficulty of damaging the grass lifting member 221 , thereby preventing the grass lifting member 221 from being damaged during the process of rolling up the weeds.
[0112] Specifically, the torsion spring includes a main body 2211, a first arm 2212 and a second arm 2213. The main body 2211 is arranged around the second positioning portion 2111 and rotates around the second positioning portion 2111; the first arm 2212 is connected to one circumferential side of the main body 2211, and the second arm 2213 is connected to the other circumferential side of the main body 2211. The first arm 2212 and the second arm 2213 can be integrally connected on both sides of the main body 2211. The first arm 2212 can be used to roll up weeds, fallen leaves and other debris.
[0113] When subjected to an external force that causes it to rotate, the first arm 2212 can drive the main body 2211 and the second arm 2213 to rotate within the second movable groove 2122 around the second positioning portion 2111. The second movable groove 2122 thereby limits the range of motion of the second arm 2213, and thus the range of motion of the grass-lifting member 221. Furthermore, when subjected to an appropriate external force, the first arm 2212 can drive the second arm 2213 to abut against the outer wall of the second connecting portion 212, thereby stopping rotation. In this case, the outer wall of the second connecting portion 212 provides support to the second arm 2213, thereby supporting the first arm 2212 of the grass-lifting member 221 and preventing the first arm 2212 from sinking into the grass.
[0114] With reference to Figures 2, 5, and 7, a connecting post 300 is protruding from the center of each second connecting portion 212 in the axial direction of the mounting plate 211.

The axis of the connecting post 300 is aligned with the axis of the mounting plate 211, allowing the second connecting portion 212 and the mounting plate 211 to rotate about the same straight line.
[0115] In this embodiment, a connecting column 300 is protruded from the center of each second connecting portion 212. It can be understood that the connecting column 300 can be fixed on the second connecting portion 212 in an integral manner, or a second mounting hole 213 passing through the second connecting portion 212 can be set on the axial center line of the mounting plate body 211.

[0117] 2 and 8 , in one embodiment, the connecting post 300 is in the shape of a quadrangular prism. When the connecting post 300 passes through the second mounting hole 213, the four corner portions of the connecting post 300 in the circumferential direction can be respectively inserted into any one of the limiting grooves 400. By rotating the connecting post 300, the four corner portions of the connecting post 300 can be respectively inserted into four of the plurality of limiting grooves 400, thereby adjusting the position at which the outer wall surface of the connecting post 300 is inserted into the inner wall surface of the second mounting hole 213, thereby adjusting the angle at which the mounting plate 211 is installed on the connecting post 300. For example, twelve limiting grooves 400 are provided.
[0118] In one embodiment, four retaining grooves 400 are provided, and the outer wall of the connecting post 300 is provided with multiple raised portions (not shown), which are evenly arranged along the circumference of the connecting post 300. When the second mounting hole 213 is formed, four of the raised portions of the connecting post 300 respectively engage with the four retaining grooves 400, allowing the position of the outer wall of the connecting post 300 to be adjusted relative to the inner wall of the second mounting hole 213, thereby adjusting the angle at which the mounting plate 211 is mounted on the connecting post 300. For example, twelve raised portions are provided.
[0119] 8 , in one embodiment, each second connecting portion 212 includes a plurality of second cylindrical bodies 2123 surrounding the second mounting hole 213. The plurality of second cylindrical bodies 2123 correspond one-to-one to the plurality of second movable grooves 2122.

Exemplarily, three second cylindrical bodies 2123 are provided and are integrally connected to the mounting plate 211.
[0120] 5 , the two second connection portions 212 are integrally connected to the mounting plate 211 , which can reduce the difficulty of installing the grass-moving single-tube assembly 200 , simplify the manufacturing process during manufacturing, and reduce manufacturing costs.
