DETAILED DESCRIPTION

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0032] Example

[0033] Reference Figures 1-10 As shown, a mowing device of the utility model includes:

[0034] The moving mechanism includes: a mounting plate 1, a fixed leg 2, a sleeve 3, a base 7, a rotating shaft 4, a first wheel 30, and a second wheel 5. The base 7 and the sleeve 3 are respectively arranged on the first surface and the second surface of the first end of the mounting plate 1. The rotating shaft 4 is fixedly connected to the base 7. The rotating shaft 4 passes through the mounting plate 1 and the sleeve 3 and extends outward. The first wheel 30 is connected to the end of the rotating shaft 4. The fixed leg 2 is arranged on the second surface of the second end of the mounting plate 1. The second wheel 5 is connected to the end of the fixed leg 2.

[0035] The mowing mechanism includes: a bracket, a driving member 23, and a cutter disc 25. The middle part of the bracket is connected to the base 7, the driving member 23 is connected to one end of the bracket, and the cutter disc 25 is connected to the output end of the driving member 23.

[0036] The cam 3 is connected to the upper surface of the cam 3 and the lower surface of the cam 3 is connected to the lower surface of the cam 3, and the upper surface of the cam 3 is connected to the lower surface of the cam 3.

[0037] Reference Figure 1 As shown, the base 7 is rotatably connected to the first surface of the mounting plate 1, and the sleeve 3 is fixedly connected to the second surface of the mounting plate 1. The rotatable connection between the base 7 and the mounting plate 1 provides rotational freedom for the mowing mechanism, allowing the operator to change the trajectory of the mowing device by adjusting the direction of the base 7. The fixed connection between the sleeve 3 and the mounting plate 1 provides radial support for the rotating shaft 4, ensuring that the rotating shaft 4 rotates along a fixed axis when the base 7 rotates, preventing steering deviation of the first wheel 30 caused by shaking of the rotating shaft 4, and improving the stability of the device's movement.

[0038] Reference Figure 1 、 Figure 3 As shown, the mounting plate 1 includes a first support plate and a second support plate, one end of the first support plate and the second support plate being connected, and the angle between the extension direction of the first support plate and the extension direction of the second support plate is an acute angle. The first support plate and the second support plate can be fixedly connected by integral molding, welding, or fastening with bolts 14 to form an inseparable unit. The trajectory of the long sides of the first support plate and the second support plate forms an angle less than 90°, such as 30°, 45°, or 60°, so that the mounting plate 1 as a whole presents a V-shaped posture with an opening to one side. This provides standing space for the operator and prevents the mounting plate 1 from obstructing the operator. In addition, when the mowing device is stored, the open side of the mounting plate 1 can provide storage space for the mowing mechanism, and the sleeve 3 and two fixed legs 2 are distributed around the mowing mechanism, ensuring safe storage of the mowing mechanism. After storage, the blade disc 25 is prevented from accidentally injuring nearby personnel or damaging the mesh plate 28.

[0039] Reference Figure 4As shown, the bracket includes: an outer tube 6, an inner tube 11 and a bolt 14. The inner tube 11 is slidably sleeved in the outer tube 6. The bolt 14 is threadedly connected to the outer tube 6. The bolt 14 can pass through the outer tube 6 to extend to the inner tube 11 and abut against the inner tube 11. The driving member 23 is installed at the end of the inner tube 11. The inner tube 11 is provided with a slide groove 12 along its length direction. The inner wall of the outer tube 6 is provided with a limit block 13 slidably connected to the slide groove 12. The outer cylinder 6 serves as the fixed basic component of the bracket, and its middle part is connected to the base 7 to form a stable support base point. The inner cylinder 11 is slidably sleeved inside the outer cylinder 6, and the two are clearance-matched to ensure smooth sliding. The driving member 23 is installed at the end of the inner cylinder 11 to move with the sliding of the inner cylinder 11. The driving member 23 and the cutter disc 25 are adjusted in position through the expansion and contraction of the inner cylinder 11; the bolt 14 is threadedly connected to the side wall or top of the outer cylinder 6. After tightening, it can pass through the outer cylinder 6 and extend to the outer wall of the inner cylinder 11 and abut against it, thereby realizing the relative fixation of the inner cylinder 11 and the outer cylinder 6.

[0040] Reference Figure 3-Figure 4 As shown, the stopper 13 slides into the chute 12, forming a guide and anti-rotation fit. By adjusting the length of the chute 12, the ends of the chute 12 limit the travel of the stopper 13. The outer tube 6 and the inner tube 11 are both made of aluminum alloy. When the inner tube 11 extends outward from the outer tube 6, when the inner wall of the end of the chute 12 on the inner tube 11 contacts the stopper 13, the inner tube 11 cannot extend further out of the outer tube 6, thereby maintaining the inner tube 11 and the outer tube 6. The connection state is prevented, and the inner tube 11 is prevented from completely falling out of the outer tube 6.

[0041] The base 7 is removably provided with a clamping member 9, and the central portion of the outer tube 6 is removably mounted between the base 7 and the clamping member 9. Each base 7 and the clamping member 9 has a groove. When assembled, the through-holes of the base 7 and the clamping member 9 are shaped to match the shape of the outer tube 6. The fastener 10 comprises a flange and a threaded member. Flanges extend along the planar edges of the opposing end surfaces of the base 7 and the clamping member 9, and the flanges are locked together by a threaded member. When the flanges are locked, they drive the clamping member 9 to press against the base 7, thereby pressing and securing the outer tube 6. Thus, by loosening the fastener 10, the fixed position of the outer tube 6 and the base 7 can be adjusted in the longitudinal direction. By adjusting the relative position of the inner tube 11 and the outer tube 6, the position of the outer tube 6's fulcrum during installation can be adjusted, further increasing the adjustable range of the bracket. Furthermore, the removable outer tube 6 configuration allows for replacement of outer tubes 6 of different lengths or inner diameters, further expanding the range of bracket sizes available.

[0042] Reference Figure 4 As shown, a groove is provided on the lower surface of the base 7 , and the upper end of the rotating shaft 4 is located inside the groove and fixedly connected to the base 7 .

[0043] As shown in Figure 3, the end of the outer tube 6 away from the inner tube 11 is connected to a side plate 15, and the two ends of the side plate 15 are respectively connected to the handle assembly. The side plate 15 serves as the mounting base for the handle assembly and is fixedly connected to the rear end of the outer tube 6. For example, the distal end of the outer tube 6 is the end closest to the user, and the opening direction of the mounting plate 1 is also oriented toward this end. The side plate 15 forms a support structure perpendicular to the extension direction of the outer tube 6. The handle assembly is arranged in pairs, connected to the two ends of the side plate 15, namely the left and right sides along the width of the device, providing a two-handed grip for the operator.

[0044] Each handle assembly consists of two parts: a column 16 and a hand tube 17. The column 16 is a cylindrical structure, and the hand tube 17 is a hollow cylindrical structure that is sleeved on the column 16. The hand tube 17 is made of rubber or non-slip plastic. Its inner wall is interference fit with the column 16 to ensure that it is not loose. The outer wall is provided with anti-slip textures such as wavy patterns or granular protrusions to increase friction when holding and prevent slipping.

[0045] Reference Figure 2 As shown, the end of the inner cylinder 11 is detachably connected to a mounting bracket 21, which is fixedly connected to a fixing base 20. A stud 22 is rotatably connected to the mounting bracket 21, which is threaded into the fixing base 20. The fixing base 20 is connected to a fixing rod 19, which passes through the inner cylinder 11 and is connected to a drive member 23. The mounting bracket 21 is a frame-like structure, detachably connected to the inner cylinder 11 via a threaded or plug-in connection. To adjust the mowing height, the operator rotates the handle of the stud 22. Since the stud 22 is rotatably connected to the mounting bracket 21, and the fixing base 20 is fixed to the mounting bracket 21, the counterclockwise rotation of the stud 22 causes it to move along the threaded direction toward or away from the fixing base 20. This movement of the stud 22 causes the fixing rod 19 to slide up and down synchronously, which in turn pushes the drive member 23 up and down, causing the cutterhead 25 to move closer to or further from the ground, thereby controlling the height of the remaining grass.

[0046] Reference Figure 4 、 Figure 9 、 Figure 10 As shown, in order to improve the rotation stability, reduce wear and rotational friction, in an optional embodiment, a first end face bearing 31 is provided between the base 7 and the mounting plate 1, the base 7 is fixedly mounted on the top of the first end face bearing 31, and the bottom of the first end face bearing 31 is fixedly mounted on the mounting plate 1, so that the base 7 is rotatably connected to the mounting plate 1 through the first end face bearing 31, thereby providing axial support for the base 7 and the mounting bracket, and does not affect the rotation of the base 7 and the rotating shaft 4 relative to the mounting plate 1; a second end face bearing (not shown in the figure) is provided between the bottom of the sleeve 3 and the first wheel 30, providing axial support between the bottom end face of the sleeve 3 and the top of the first wheel 30, and does not affect the rotation of the first wheel 30 and the rotating shaft 4 relative to the sleeve 3.

[0047] Reference Figure 1 、 Figure 5 As shown, the end of the fixed rod 19 is connected to the connecting rod 18, and the driving member 23 is arranged at the end of the connecting rod 18. The driving member 23 is sleeved with a net tube 27, and the two sides of the net tube 27 are connected to the net plate 28. The driving member 23 is connected to the end of the connecting rod 18 and sleeved within the net tube 27. The outer surface of the motor is provided with a net tube 27, and two curved net plates 28 are respectively provided on both sides of the net tube 27. The net plates 28 are mounted to the driving member 23, i.e., the outer surface of the motor through the net tube 27. The net tube 27 and the net plates 28 are both made of a plastic material with a certain degree of toughness and high temperature resistance, and can also be made of metal. When mowing, the cutterhead 25 moves simultaneously with the net tube 27 and the net plates 28, and the cutterhead 25 can achieve mowing, and the net tube 27 and the net plates 28 can collect the cut grass and uniformly place it on both sides of the device, so that during the reciprocating mowing process of the cutterhead 25, the cut grass will not affect the cutterhead 25.

[0048] The mesh 28 extends vertically to prevent grass clippings from splashing horizontally to the sides. It is configured as an arc-shaped mesh 28, with its dimensions along the plane of the cutter disc 25 being larger than those of the cutter disc 25. Compared to a flat structure, this arc-shaped structure guides grass clippings more smoothly along the curved surface and increases the mesh 28's capacity for mowed grass. This guiding effect allows mowed grass clippings to accumulate in a concentrated strip on either side of the device, rather than being scattered throughout the mowing area, significantly reducing the workload of subsequent grass harvesting.

[0049] The cutter disc 25 is sleeved on the output end of the driver 23. The output end of the driver 23 is fixedly connected to a limit disc 24 and is threadedly connected to a nut 26. The cutter disc 25 is disposed between the limit disc 24 and the nut 26. The cutter disc 25 is provided with a positioning hole, and the limit disc 24 is provided with a positioning protrusion 29 that fits within the positioning hole. The end of the output end of the driver 23 is configured with threads that fit within the nut 26. By tightening the nut 26, the cutter disc 25 is axially clamped between the limit disc 24 and the nut 26. The positioning structure comprises a positioning hole on the cutter disc 25 and a positioning protrusion 29 on the limit disc 24. The positioning protrusion 29 fits into the positioning hole to achieve circumferential fixation between the cutter disc 25 and the output end, thereby preventing relative rotation.

[0050] Reference Figure 1 As shown, a power module 8 and a corresponding switch module can be set on the outer cylinder 6. The power module 8 and the switch module can be used to power the motor. Since the power module 8 and the mowing unit are respectively located on both sides of the rotating shaft 4, the power module 8 can assist the outer cylinder 6 and the inner cylinder 11 in maintaining a certain balance weight, thereby preventing the end of the outer cylinder 6 away from the mowing unit from tilting upward too much, thereby improving the stability of the device.

[0051] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of this utility model.
