Description

Technical Field

[0001] This application relates to the technical field of lawnmowers, and particularly to a cutting mechanism and a lawnmower. Background Technology

[0002] Lawn mowers are used for cutting lawns in yards. When a lawn mower is working, the cutting blades rotate, and the mower can move on the ground to complete the mowing of the area covered and / or the area around the mower. Currently, some cutting blades extend beyond the mower's casing when rotating, posing a risk of accidental injury to people passing through the mower's operating area, thus compromising the safety of lawn mowers. Summary of the Invention

[0003] In view of the above, it is necessary to provide a cutting mechanism and a lawnmower to solve the above-mentioned defects.

[0004] In a first aspect, embodiments of this application provide a cutting mechanism, comprising: a housing, an accommodating space formed within the housing, and a grass inlet communicating with the accommodating space on the periphery of the housing, the grass inlet being used to allow external grass vegetation to enter the accommodating space; a cutting blade, fixedly disposed within the accommodating space; and a grass feeding assembly, rotatably disposed within the accommodating space, the grass feeding assembly and the cutting blade being spaced apart in the height direction, the grass feeding assembly rotating to contact the grass vegetation at the grass inlet and pushing the grass vegetation to the cutting blade for cutting.

[0005] Optionally, the grass feeding assembly includes: a rotating disk rotatably disposed within a receiving space; and at least one grass hook disposed on the periphery of the rotating disk for hooking and pushing grass vegetation.

[0006] Optionally, there are multiple hook sections, which are evenly distributed along the circumference of the rotating disk.

[0007] Optionally, the hook section includes: a connecting section connected to the rotating disk; and a hook section connected to the connecting section, wherein the hook section extends outward from the end of the connecting section and bends in the direction of rotation of the rotating disk.

[0008] Optionally, there are multiple hook sections, which are arranged opposite each other in the height direction and spaced apart. The two hook sections opposite each other in the height direction rotate synchronously, and a clearance space is formed between the two hook sections for the cutting blade to pass through.

[0009] Optionally, multiple grass inlets are provided, and a set of cutting blades is provided between two adjacent grass inlets.

[0010] Optionally, the housing is constructed with multiple blade mounting sections located between two adjacent grass inlets, and the cutting blades are disposed within the blade mounting sections.

[0011] Optionally, the blade mounting section includes a top wall and a bottom wall disposed opposite to each other, and an outer wall connecting the top wall and the bottom wall. The top wall, the bottom wall and the outer wall enclose a blade protection space, and the cutting blade is located within the blade protection space.

[0012] Optionally, the outer casing is provided with a grass discharge port communicating with the receiving space on its periphery, and the grass inlet and the grass discharge port are arranged sequentially on the periphery of the outer casing along the rotation direction of the grass feeding assembly.

[0013] Optionally, the cutting mechanism also includes a drive component, which is mounted on the housing. The output end of the drive component is connected to the feeding assembly to drive the feeding assembly to rotate.

[0014] Secondly, embodiments of this application provide a lawnmower, including a body and the cutting mechanism described above.

[0015] Optionally, the cutting mechanism is located on the outside of the machine body for cutting the edges of the grass to be cut.

[0016] With the cutting mechanism and lawnmower provided in this application, when the lawnmower is working and traveling on the grass, grass vegetation can enter the receiving space through the grass inlet, and the rotating grass feeding component can contact the grass vegetation in the grass inlet; the grass feeding component can push the grass vegetation to contact the cutting blade by rotating, thereby realizing the cutting of the grass vegetation by the cutting blade.

[0017] In this way, during the movement of the lawnmower, the grass feeding component can rotate and push the grass vegetation to the cutting blade, thereby bringing the grass vegetation close to the cutting blade and cutting it. The relative fixation of the cutting blade and the outer casing can reduce the risk of injury to personnel from the cutting blade. This enhances personnel protection during lawnmower operation and improves the safety of the lawnmower. At the same time, the grass feeding component can drive the grass vegetation to automatically approach the cutting blade, thereby reducing the occurrence of grass vegetation in the area where the lawnmower passes that cannot approach the cutting blade due to being blocked by the outer casing. This reduces the number of grass vegetation that cannot be cut due to obstruction by the outer casing, thereby improving the uniformity of grass vegetation height in the area after lawnmower operation and improving the effectiveness of lawnmower operation.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

[0027] The term "multiple" in this application refers to two or more. Furthermore, it should be understood that the terms "first," "second," etc., used in the description of this application are used only for descriptive purposes and should not be construed as indicating or implying relative importance, nor as indicating or implying order.

[0028] In the description of the embodiments in this application, the words "exemplary" or "for example" are used to indicate that they are examples, illustrations, or descriptions. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design options. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0029] Please see Figure 1 , Figure 1 An embodiment of the present application provides a lawnmower 100.

[0030] In the embodiments of this application, the lawnmower 100 may include a body 101, a traveling mechanism 102, and a cutting mechanism 103. The traveling mechanism 102 may be fixedly mounted on the body 101. The traveling mechanism 102 may be a wheeled or tracked mechanism. The traveling mechanism 102 may come into contact with the ground and move relative to the ground during operation, so that the body 101 can travel on the ground, thereby enabling the lawnmower 100 to travel on the ground.

[0031] The cutting mechanism 103 can be connected to the body 101. The cutting mechanism 103 can extend outward from the body 101. While the lawnmower 100 is moving on the grass, the cutting mechanism 103 extending outward from the body 101 can contact the edge of the grass. At this time, the cutting mechanism 103 can work to cut the grass vegetation at the edge of the grass, so that the grass vegetation on the grass is cut to the same or similar height.

[0032] In the embodiments of this application, the connection method between the cutting mechanism 103 and the machine body 101 is not specifically limited. For example, the cutting mechanism 103 can be fixedly installed on the outside of the machine body 101. As another example, the cutting mechanism 103 can be movably connected to the inside or bottom of the machine body 101, and a mechanism for driving the cutting mechanism 103 to move can be provided between the cutting mechanism 103 and the machine body 101, so that the cutting mechanism 103 can extend out of the machine body 101 and cut grass vegetation.

[0033] It is understood that the body 101 may have a front end and a rear end that are arranged opposite to each other. The front end may be the end of the body 101 facing the forward direction when the lawnmower 100 is moving. At the same time, the body 101 may include two sides that are arranged opposite to each other. The relative direction of the two sides may be the width direction of the body 101, and the relative direction of the front end and the rear end may be the length direction of the body 101.

[0034] In some cases, such as Figure 1 As shown, the cutting mechanism 103 can be disposed on at least one side of the body 101, and the lawnmower 100 can be fixedly connected to the body 101 or movably connected to the body 101 along the width direction of the body 101. When the cutting mechanism 103 is working, it can extend to the side of the body 101 to cut the grass vegetation on the side of the body 101.

[0035] Meanwhile, a working mechanism can be provided at the front and / or rear of the machine body 101. The working mechanism can cut the grass vegetation at the front and / or rear of the machine body 101 in the same or different manner as the cutting mechanism 103. In this way, the grass mowing operation can be completed while the lawnmower 100 is traveling on the grass.

[0036] In other cases, a cutting mechanism 103 is provided at least at one end of the front end and the rear end of the fuselage 101. The cutting mechanism 103 can be fixedly connected to the fuselage 101 or movably connected to the fuselage 101 along the length direction of the fuselage 101. Furthermore, a cutting mechanism 103 is provided on at least one side of the fuselage 101. The cutting mechanism 103 can be fixedly connected to the fuselage 101 or movably connected to the fuselage 101 along the width direction of the fuselage 101.

[0037] As the lawnmower 100 travels, each cutting mechanism 103 can extend from the body 101 and cut the grass vegetation it comes into contact with. In this way, the lawnmower 100 can complete the mowing operation while traveling on the grass.

[0038] In other cases, a cutting mechanism 103 is provided at least at one end of the front and rear of the body 101, or at least on one side of the body 101. While the lawnmower 100 is in motion, the cutting mechanism 103 can extend out of the body 101 and cut the grass vegetation it contacts. In this way, the lawnmower 100 can complete the mowing operation while traveling on the grass.

[0039] In the embodiments of this application, the fixing method for fixed installation and fixed connection is not specifically limited. For example, the fixing method may include, but is not limited to, bolt fixing, screw fixing, welding fixing, integral molding fixing, and interference fit fixing.

[0040] It is understood that when the cutting mechanism 103 is movably mounted on the machine body 101, the cutting mechanism 103 can achieve linear or arc trajectory movement on the machine body 101 through structures such as slide rails and slide grooves, and can achieve movement on the machine body 101 through the drive of equipment such as motors and cylinders. The embodiments of this application do not limit this.

[0041] Please refer to the following: Figures 2 to 4 In some embodiments, the cutting mechanism 103 may include a housing 10, a cutting blade 20, a grass feeding assembly 30, and a drive component 40.

[0042] The outer casing 10 may have an internal receiving space 11, and the periphery of the outer casing 10 may be provided with a grass inlet 12 and a grass outlet 13. The grass inlet 12 and the grass outlet 13 are spaced apart along the direction surrounding the outer casing 10. The grass inlet 12 communicates with the receiving space 11, and the grass outlet 13 also communicates with the receiving space 11. The grass inlet 12 can penetrate the outer periphery of the outer casing 10 and pass through both sides of the outer casing 10 in the height direction. The grass outlet 13 can penetrate the outer periphery of the outer casing 10.

[0043] The cutting blade 20 and the grass feeding assembly 30 can be housed within the receiving space 11. The cutting blade 20 can be fixedly connected to the housing 10, thereby being fixedly disposed within the receiving space 11. The cutting blade 20 can avoid the grass feeding assembly 30. The grass feeding assembly 30 is rotatably connected to the housing 10, thereby being rotatably disposed within the receiving space 11. The periphery of the grass feeding assembly 30 can pass through the grass inlet 12. The drive component 40 can be disposed on the housing 10, and the output actuator of the drive component 40 can be fixedly connected to the grass feeding assembly 30. The operation of the drive component 40 can drive the grass feeding assembly 30 to rotate. The rotation direction of the grass feeding assembly 30 can coincide with the direction surrounding the housing 10.

[0044] In embodiments of this application, the length, width, and height directions of the lawnmower 100 and the cutting mechanism 103 can be defined as a first direction, a second direction, and a third direction, respectively. The first direction, the second direction, and the third direction are perpendicular to each other. For example, the first direction could be... Figure 1 and Figure 2 The X direction and its opposite direction are shown. The second direction can be... Figure 1 and Figure 2 The Y-direction and its opposite direction are shown. The third direction can be... Figure 2 The Z direction and its opposite direction are shown.

[0045] The height direction of the outer shell 10 can coincide with the third direction, and the axial direction of the grass feeding assembly 30 can coincide with the third direction.

[0046] It is understandable that when the lawnmower 100 is working, it travels on the grass, and the grass on the grass can enter the receiving space 11 through the grass inlet 12. At this time, the rotating grass feeding component 30 can come into contact with the grass inlet 12 and push the grass to the cutting blade 20, so that the cutting blade 20 cuts the grass. Then, the cut part of the grass can pass through the grass discharge port 13 through inertia and / or under the push of the grass feeding component 30, and be thrown out of the outer shell 10 from the grass discharge port 13. In this way, the lawnmower 100 and the cutting mechanism 103 can carry out the grass mowing operation.

[0047] Compared to related methods where the cutting mechanism 103 moves across the grass, causing the rotating cutting blade 20 to extend from the body 101 to cut grass, the embodiment of this application fixes the cutting blade 20 within the receiving space 11. During the movement of the cutting mechanism 103, the grass feeding assembly 30 rotates to push the grass towards the cutting blade 20, thereby cutting the grass. This reduces the risk of injury to personnel from the cutting blade 20, enhancing personnel protection and improving the safety of the lawnmower 100 during mowing operations. Simultaneously, the grass feeding assembly 30 can automatically drive the grass towards the cutting blade 20, reducing the occurrence of grass that cannot reach the cutting blade 20 due to obstruction by the outer casing 10. This reduces the number of grasses that cannot be cut due to obstruction by the outer casing 10, improving the uniformity of grass height in the area after mowing and enhancing the mowing effect.

[0048] In some embodiments, the number of grass inlets 12 can be multiple, and the multiple grass inlets 12 can be spaced apart in the direction surrounding the housing 10. The number of cutting blades 20 can be multiple, and the multiple cutting blades 20 can be spaced apart in the direction surrounding the housing 10. A set of cutting blades 20 is provided between every two adjacent grass inlets 12, and the number of cutting blades 20 in each set of cutting blades 20 can be one or more. When the number of cutting blades 20 in each set of cutting blades 20 is multiple, the multiple cutting blades 20 can be arranged opposite each other and spaced apart in the third direction. The multiple grass inlets 12 can be located on the same side of the housing 10.

[0049] It is understood that multiple grass inlets 12 can all be located on the same side of the outer casing 10 in the second direction, and multiple cutting blades 20 can all be located on the same side of the receiving space 11 in the second direction. The cutting blades 20 can be arranged to avoid collision with the grass feeding assembly 30 in the third direction. When the grass feeding assembly 30 pushes the grass at the grass inlet 12, it can make the grass contact the cutting blades 20 without colliding with them, thereby achieving the cutting of the grass by the cutting blades 20.

[0050] It is understood that there can be one or more grass discharge ports 13. In the direction of rotation of the grass feeding assembly 30, all grass discharge ports 13 are located outside all grass inlets 12, and at least partially located on the side of the outer shell 10 away from the grass inlets 12 in the second direction, so that all grass inlets 12 and all grass discharge ports 13 are arranged sequentially around the periphery of the outer shell 10. Grass vegetation can enter the receiving space 11 from the side where the grass inlets 12 are located, and can be thrown out of the outer shell 10 from the side where the grass discharge ports 13 are located.

[0051] In some embodiments, the periphery of the housing 10 may be provided with a plurality of blade mounting portions 14, which may be spaced apart along the direction surrounding the housing 10, and a grass inlet 12 may be provided between every two adjacent blade mounting portions 14, that is, a blade mounting portion 14 may be provided on each side of each grass inlet 12.

[0052] Each set of cutting blades 20 can be housed in the corresponding blade mounting part 14 and fixedly connected to the blade mounting part 14. The length direction of each cutting blade 20 can coincide with the radial direction of the housing 10 and the grass feeding assembly 30, the height direction of each cutting blade 20 can coincide with the third direction, and the width direction of each cutting blade 20 can be perpendicular to its length and height directions.

[0053] Each blade mounting portion 14 may include a top wall 141 and a bottom wall 142 disposed opposite each other in a third-party upward direction, and an outer wall 143 integrally connected between the top wall 141 and the bottom wall 142. The top wall 141 and the bottom wall 142 of the blade mounting portion 14 can cover the top and bottom of the cutting blade 20 from a third-party upward direction. The outer wall 143 of the blade mounting portion 14 may include a first connecting portion 1431 extending in a direction surrounding the housing 10, and a second connecting portion 1432 located on both sides of the first connecting portion 1431. The second connecting portion 1432 can extend from both sides of the first connecting portion 1431 radially toward the receiving space 11 of the housing 10. The first connecting portion 1431 can cover the side of the cutting blade 20 near the outer periphery of the housing 10 in the length direction. In this way, the top wall 141, the bottom wall 142, the first connecting portion 1431, and the second connecting portion 1432 of each blade mounting portion 14 can cooperate to form a protective space 144, and each cutting blade 20 can be located in the corresponding protective space 144. Each second connecting portion 1432 extends radially along the outer casing 10 for a length less than the length of the cutting blade 20. Each cutting blade 20, with one end facing away from the corresponding first connecting portion 1431 in the length direction, can protrude radially from the second connecting portion 1432 of the outer casing 10, thus exposing itself from the protective space 144. Each protective space 144 can cooperate to form the outer periphery of the receiving space 11 and can communicate with the adjacent grass inlet 12.

[0054] When the grass feeding assembly 30 rotates, it can push grass vegetation from the grass inlet 12 into the receiving space 11, where it comes into contact with the cutting blade 20 exposed from the protective space 144, thereby enabling the cutting blade 20 to cut the grass vegetation. At the same time, the blade mounting part 14 can enhance the protection of each cutting blade 20. The blade mounting part 14 can block hard objects such as gravel and sand on the grass, thereby reducing the probability of the cutting blade 20 being damaged by collision with hard objects when the cutting mechanism 103 is working, and increasing the service life of the cutting blade 20.

[0055] It can be understood that radial direction can be the direction in which the diameter of a component with a circular or annular cross-section lies.

[0056] Please refer to the following: Figure 5 In some embodiments, all blade mounting portions 14 may be arranged sequentially in the direction surrounding the housing 10. Of all the blade mounting portions 14, except for the two outermost blade mounting portions 14, the remaining blade mounting portions 14 may form extensions extending radially along the housing 10 and formed between two adjacent grass inlets 12. The extension direction of each extension coincides with a radial direction of the housing 10. A reinforcing rib 15 may be fixedly connected to each extension to improve its structural strength.

[0057] In the embodiments of this application, the number of cutting blades 20, grass inlet 12 and extension is not specifically limited.

[0058] For example, such as Figure 3 and Figure 5 As shown, the number of cutting blades 20 can be five sets, and the five sets of cutting blades 20 can be arranged at intervals along the direction surrounding the outer casing 10. A grass inlet 12 is formed between every two adjacent sets of cutting blades 20, meaning the outer casing 10 has four grass inlets 12. An extension is formed between every two adjacent grass inlets 12, and a blade mounting portion 14 is provided on each side of each grass inlet 12; that is, the outer casing 10 has five blade mounting portions 14, and the three blade mounting portions 14 located in the middle of the five blade mounting portions 14 form three extensions on the outer casing 10. Each set of cutting blades 20 is housed within the protective space 144 in the corresponding blade mounting portion 14.

[0059] Please refer to the following: Figures 5 to 7 In some embodiments, the housing 10 may include a top cover 16 and a bottom plate 17. The top cover 16 and the bottom plate 17 may be spaced apart in a third-order direction and fixedly connected. The top cover 16 and the bottom plate 17 may enclose and form an accommodating space 11. Each grass inlet 12 may penetrate the top cover 16 and the bottom plate 17 in a third-order direction. The top wall 141 of each blade mounting portion 14 may be formed in the top cover 16, and the bottom wall 142 may be formed in the bottom plate 17.

[0060] Multiple first connecting seats 161 can be fixedly connected to the side of the top cover 16 facing the bottom plate 17, and the multiple first connecting seats 161 are spaced apart along the direction surrounding the top cover 16. Multiple second connecting seats 171 can be fixedly connected to the side of the bottom plate 17 facing the top cover 16, and the multiple second connecting seats 171 are spaced apart along the direction surrounding the bottom plate 17. The multiple second connecting seats 171 correspond one-to-one with the multiple first connecting seats 161. Each first connecting seat 161 has a positioning groove 162 on the side facing the bottom plate 17, and each second connecting seat 171 can be inserted into the corresponding positioning groove 162 to achieve positioning of the top cover 16 and the bottom plate 17.

[0061] In the embodiments of this application, the position and number of the first connecting seat 161 and the second connecting seat 171 are not specifically limited.

[0062] For example, the number of first connecting seats 161 and second connecting seats 171 can both be three. Of the three first connecting seats 161, two are respectively positioned corresponding to the two outermost blade mounting portions 14 among the plurality of blade mounting portions 14, and are located on the side of the corresponding blade mounting portion 14 facing away from the grass inlet 12, while being fixedly connected to the blade mounting portion 14 and the top cover 16; the remaining first connecting seat 161 is located on the side of the top cover 16 facing away from all grass inlets 12 in a second direction. The three first connecting seats 161 can separate the area between the top cover 16 and the base plate 17 where no grass inlet 12 is provided, forming two grass discharge outlets 13. Simultaneously, each second connecting seat 171 can be inserted into the positioning groove 162 on the corresponding first connecting seat 161. Exemplarily, the first connecting seat 161, the blade mounting portion 14, and the top cover 16 can be integrally formed and fixed, and the second connecting seat 171 and the base plate 17 can be integrally formed and fixed.

[0063] It is understood that after the second connector 171 is inserted into the corresponding positioning slot 162, the operator can use fasteners to fix the top cover 16 to the base plate 17 to complete the assembly of the outer casing 10. The fasteners can be, but are not limited to, screws.

[0064] The fasteners can be used to fix the top cover 16 and the bottom plate 17 by fastening the first connecting seat 161 and the second connecting seat 171.

[0065] It is understandable that when the cutting blade 20 needs to be replaced or maintained due to wear, the operator can disassemble the housing 10 by removing the fasteners on the first connecting seat 161 and the second connecting seat 171, then remove the cutting blade 20 from the top cover or bottom plate 17, and then install the new cutting blade 20 or the maintained cutting blade 20 back on the top cover or bottom plate 17. Then, the housing 10 is reassembled by positioning the first connecting seat 161 and the second connecting seat 171 and fixing the fasteners, thereby completing the replacement or maintenance of the cutting blade 20.

[0066] In some cases, the cutting blade 20 can be fixedly connected to the top cover 16 using fasteners. In other cases, the cutting blade 20 can be fixedly connected to the base plate 17 using fasteners. The embodiments of this application do not limit the connection position of the cutting blade 20.

[0067] In some embodiments, the grass feeding assembly 30 may include a rotating disk 31 and grass hooks 32. The rotating disk 31 is a disc. Multiple grass hooks 32 are arranged at the same height in a third direction, and these hooks 32 are evenly distributed around the circumference of the rotating disk 31 and fixedly connected to it. The multiple grass hooks 32 are spaced apart from each cutting blade 20 in a third direction. The rotating disk 31 is fixedly connected to the output execution end of the drive component 40. The drive component 40 drives the rotating disk 31 to rotate, thereby causing the grass hooks 32 to rotate. When the grass hooks 32 rotate, they can pass through the grass inlet 12 and hook the grass located at the grass inlet 12 to abut against it. As the grass hooks 32 continue to rotate, they can push the hooked grass to each cutting blade 20 for cutting. After cutting, the grass can be thrown out of the grass discharge outlet 13 by inertia or by the continued hooking and pushing of the grass hooks 32.

[0068] Multiple hook sections 32 located at the same height in the third direction can form a row of hook sections 32. The hook sections 32 can be arranged in one or more rows. When multiple rows of hook sections 32 are arranged, they can be arranged opposite each other and spaced apart in the third direction. In this case, multiple hook sections 32 in each row correspond one-to-one with multiple hook sections 32 in the adjacent row, and the projection of each hook section 32 in the third direction coincides with the projection of its corresponding other hook sections 32 in the third direction.

[0069] In some embodiments, the hook grass section 32 is arranged in multiple rows, and a clearance space 33 is formed between every two adjacent rows of hook grass sections 32. The clearance space 33 can accommodate at least one cutting blade 20 from each group of cutting blades 20.

[0070] In this way, the multiple rows of hook sections 32 can rotate synchronously, and two adjacent rows of hook sections 32 can abut against different heights of the same grass vegetation and push the grass vegetation to move synchronously, so that the grass vegetation is close to the cutting blade 20 located between the two hook sections 32. This allows the cutting blade 20 to cut the grass vegetation located between the two hook sections 32. During the cutting process, the two hook sections 32 continuously abut against the grass vegetation, thereby supporting the grass vegetation and reducing the occurrence of the grass vegetation bending due to the pressure applied by the cutting blade 20 when cutting the grass vegetation. This also reduces the occurrence of grass vegetation not being cut due to bending and the height of the cut position deviating from the preset height. As a result, the uniformity of the grass vegetation height in the area after the lawnmower 100 has finished cutting the grass vegetation can be improved, and the cutting effect of the cutting mechanism 103 and the lawnmower 100 on the grass vegetation can be improved.

[0071] In some cases, in each set of cutting blades 20, each cutting blade 20 is located within the clearance space 33 between two adjacent rows of hook grass sections 32, thereby cutting the middle of the grass vegetation pushed by the two rows of hook grass sections 32. In other cases, in each set of cutting blades 20, some cutting blades 20 are located within the clearance space 33 between two adjacent rows of hook grass sections 32, so that each clearance space 33 is provided with a cutting blade 20 capable of cutting grass vegetation; the remaining cutting blades 20 may be located on the side of the top row of hook grass sections 32 facing away from the remaining hook grass sections 32, and / or on the side of the bottom row of hook grass sections 32 facing away from the remaining hook grass sections 32. The embodiments of this application do not limit this.

[0072] In some cases, when multiple rows of hook sections 32 are arranged, the number of rotating disks 31 can be one, and all rows of hook sections 32 are fixedly connected to the periphery of the rotating disk 31. In other cases, when multiple rows of hook sections 32 are arranged, the number of rotating disks 31 can be multiple, and the multiple rotating disks 31 can be arranged at intervals in a third direction, with each row of hook sections 32 fixedly connected to the periphery of the corresponding rotating disk 31. The embodiments of this application do not limit this.

[0073] In some embodiments, each hook section 32 may include a connecting segment 321 and a hook segment 322. The connecting segment 321 may be fixedly connected to the periphery of the rotating disk 31 and extends in a direction away from the center of the rotating disk 31. The hook segment 322 may be fixedly connected to the end of the connecting segment 321 and extends outward from the end of the connecting segment 321 and bends towards the rotation direction of the rotating disk 31. The end of the connecting segment 321 is the end of the connecting segment 321 that is away from the rotating disk 31 in its extending direction.

[0074] It is understood that the connecting segment 321 can contact and push the grass vegetation, and the hooking segment 322 can block the grass vegetation that contacts the connecting segment 321 from the outside, thereby realizing and maintaining the hooking of the grass vegetation by the hooking part 32.

[0075] In some embodiments, the cutting mechanism 103 may further include a mounting base 50. The mounting base 50 is hollow and can be fixedly mounted on the top cover 16. The body 101 of the drive component 40 can be fixedly mounted on the side of the mounting base 50 away from the housing 10. The mounting base 50 can accommodate a gear set (not shown), which can be fixedly connected to the rotating disk 31 and to the output actuator of the drive component 40. When the drive component 40 operates, it can rotate the output actuator, thereby moving the gear set. The gear set can transmit the power generated by the drive component 40 to the rotating disk 31, thereby causing the feed assembly 30 to rotate.

[0076] In the embodiments of this application, the type of the driving component 40 is not specifically limited. For example, the driving component 40 may be, but is not limited to, a motor. For example, the driving component 40 may be a motor, and the output execution end of the driving component 40 may be the output shaft of the driving component 40.

[0077] It is understandable that the principle of the motor and gear set working together to make the component rotate is a common principle in the relevant field, and will not be elaborated here.

[0078] In some embodiments, the gear set may not be provided within the mounting base 50. The mounting base 50 can be fixedly mounted on the top cover 16, thereby providing a mounting position for the drive component 40. The connecting shaft of the drive component 40 can be coaxially and fixedly connected to the rotating disk 31.

[0079] In some other embodiments, the cutting mechanism 103 may not include the mounting base 50, the body 101 of the drive component 40 may be fixedly mounted on the top cover 16 and / or the bottom plate 17, and the output execution end of the drive component 40 may be fixedly connected to the rotating disk 31 or connected through a gear set.

[0080] With the cutting mechanism 103 and lawnmower 100 provided in the embodiments of this application, when the lawnmower 100 is working and traveling on the grass, the grass feeding component 30 can rotate and come into contact with the grass vegetation passing through the grass inlet 12 during the movement of the lawnmower 100; the grass feeding component 30 can push the grass vegetation that has entered the receiving space 11 through the grass inlet 12, so that the grass vegetation abuts against the cutting blade 20, thereby realizing the cutting of the grass vegetation by the cutting blade 20. The cut grass vegetation can be thrown out of the cutting mechanism 103 through the grass discharge port 13. As the lawnmower 100 moves, grass vegetation on the grass can continuously enter the grass inlet 12; the grass feeding component 30 can continuously push the grass vegetation in the grass inlet 12 to the cutting blade 20, thereby realizing the grass mowing operation of the lawnmower 100 and the cutting mechanism 103 on the grass.

[0081] Thus, in the embodiments of this application, during the movement of the cutting mechanism 103, the grass feeding component 30 can rotate to push the grass vegetation in the receiving space 11 to move, thereby cutting the grass vegetation by the cutting blade 20 fixedly set in the receiving space 11. The relative fixation between the cutting blade 20 and the outer shell 10 can reduce the risk of injury to personnel caused by the cutting blade 20, enhance personnel protection when the lawnmower 100 is performing lawn mowing operations, and improve the safety of the lawnmower 100. At the same time, the grass feeding component 30 can push the grass vegetation to automatically approach the cutting blade 20, thereby reducing the occurrence of grass vegetation in the area passed by the lawnmower 100 that cannot approach the cutting blade 20 due to being blocked by the outer shell 10. This can reduce the number of grass vegetation that cannot be cut due to being blocked by the outer shell 10, thereby improving the uniformity of grass vegetation height in the area after the lawnmower 100 has performed lawn mowing operations, and improving the effect of lawn mowing operations.

[0082] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments described above should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application.
