[0053] It is also to be understood that the present application will be described in terms of a few embodiments only and with reference to the accompanying drawings. These are exemplary of the application and are intended to provide an overview or framework for understanding the nature and character of the application as it can be used in practice. The drawings and descriptions should not be understood as limiting the present application in any way.

[0054] Furthermore, in the following description, numerous specific details are set forth in order to provide a thorough understanding of the examples. However, it will be recognized by one skilled in the art that embodiments, although details is provided, can be practiced without these specific details. In other instances, well-known methods have not been described in detail or have been described only generally.

[0055] The technical solutions provided by the embodiments of the present application are described below with reference to the drawings.

[0056] Referring to Figures 1 to 21 The present application provides a self-walking garden mower, comprising: a frame 1, a floating cutter head 5, a walking mechanism, a height adjustment mechanism 11, a grass collecting box 12 and a control unit which are installed on the frame 1; a gasoline engine 2 is installed on the frame 1, the gasoline engine 2 is provided with an output shaft 201 arranged along the horizontal axis direction, the gasoline engine 2 is installed with an electromagnetic clutch 3, the electromagnetic clutch 3 comprises a clutch driving wheel 4 coaxially connected with the output shaft 201; the floating cutter head 5 is swingably installed at the bottom of the frame 1, the floating cutter head 5 is installed with blades 501 arranged along the vertical axis direction and a blade driving wheel 8, the floating cutter head 5 is further installed with a reversing wheel 7, the reversing wheel 7 is used to switch the horizontal axis output power of the clutch driving wheel 4 to the vertical axis output power of the blade driving wheel 8; the clutch driving wheel 4 and the blade driving wheel 8 are in transmission engagement through a synchronous belt 9, the reversing wheel 7 and the synchronous belt 9 are matched through the setting, so that the power switching output can be realized by one synchronous belt; the walking mechanism comprises traveling wheels 10 arranged at the bottom of the frame 1, specifically comprising traveling front wheels and traveling rear wheels; the height adjustment mechanism 11 is installed on the frame 1 and is configured to adjust the height position of the floating cutter head 5 relative to the frame 1; the grass collecting box 12 is reversibly arranged at the front end of the frame 1 and located above the traveling wheels 10 (i.e. the traveling front wheels at the front end); the control unit is arranged at the rear end of the frame 1 (the control unit can be referred toFigure 21 , Figure 21 The control unit is configured to control the whole mower to move and the electromagnetic clutch 3 to work.

[0057] The electromagnetic clutch 3 is used to control the clutching relationship between the clutch driving wheel 4 and the output shaft 201, that is, to control whether the clutch driving wheel 4 rotates, so as to control the rotation of the blade 501. Figure 2 The output shaft 201 is provided with a driving wheel 202 for driving the walking mechanism to move. The output shaft 201 of the gasoline engine 2 is always rotating when the gasoline engine 2 works, so the driving wheel 202 can always be driven to rotate, and then the control unit is used to control whether the walking wheel 10 moves. The clutch driving wheel 4 is connected with the output shaft 201 through the electromagnetic clutch 3. When the blade 3 works, the clutch driving wheel 4 is connected with the output shaft 201 through the electromagnetic clutch 3. When the blade stops working, the clutch driving wheel 4 is separated from the output shaft 201 through the electromagnetic clutch 3.

[0058] In the embodiment of the present application, the horizontal axis direction of the output shaft 201 is the X-axis direction, the axis direction of the reversing wheel 7 is the Y-axis direction, and the vertical axis direction of the blade driving wheel 8 is the Z-axis direction. The X-axis, the Y-axis and the Z-axis are perpendicular to each other respectively.

[0059] Combined with Figure 1 and Figure 3 It should be pointed out that the gasoline engine 2 is arranged at the middle position of the frame 1, the grass collecting box 12 is arranged at the front end position of the frame 1, and the height adjusting mechanism 11 and the control unit are arranged at the rear end position of the frame 1. Especially, the grass collecting box 12 is arranged above the walking wheel 10 at the front end of the frame 1, and the idle space above the walking wheel 10 at the front end of the mower is reasonably utilized. In addition, a movable step is arranged between the two walking wheels 10 at the rear end of the frame 1 on one side of the rear end of the frame 1, for the operator to stand on. Therefore, from the overall space layout, the layout is compact and reasonable, so that the overall size of the whole mower is light and compact, and the space is saved, compared with the traditional mower.

[0060] In some embodiments, referring to Figures 4-8 The axis direction of the reversing wheel 7 is perpendicular to the clutch driving wheel 4 and the blade driving wheel 8 respectively. The synchronous belt 9 is in contact with the reversing wheel 7 after being twisted by 90 degrees, and the reversing wheel 7 realizes the 90-degree reversing of the synchronous belt 9 from the horizontal axis direction to the vertical axis direction, Figure 7 That is, the perspective view of the twisted synchronous belt 9. The twisted synchronous belt 9 is in contact with the reversing wheel 7 (the two are surface contact) and is guided, and the reversing wheel 7 realizes the power switching output in different directions.

[0061] It should be noted that the reversing wheel 7 and the twisted synchronous belt 9 structure adopted by the embodiment of the present application can realize the reversing output of power, and can be realized by one transmission synchronous belt, without the need of multi-stage belt transmission as in the traditional transmission structure. The overall structure is simple and reliable, involves fewer components, and has low production cost.

[0062] In some embodiments, during the swing adjustment of the floating cutter head 5, the reversing wheel 7 can be moved up or down along the vertical axis direction, and the blade driving wheel 8 can be moved away from or close to the reversing wheel 7 along the horizontal axis direction. As shown in Figure 8 The displacement amount of the reversing wheel 7 in the vertical axis direction tends to be close to the displacement amount of the blade driving wheel 8 along the horizontal axis direction, so that during the movement of the reversing wheel 7 up or down, no pulling force is generated on the synchronous belt 9, and the synchronous belt 9 is not loosened, so that the service life of the synchronous belt 9 is not affected.

[0063] In some embodiments, a guide flange 13 is installed in the rack 1, and the floating cutter head 5 is movably installed with a guide seat 14 which can slide along the horizontal axis direction. The reversing wheel 7 is rotatably installed on the guide seat 14, and the guide seat 14 is provided with a vertical sliding groove 15 vertically matched with the guide flange 13, for limiting the reversing wheel 7 on the guide seat 14 to move only along the vertical axis direction (Z-axis direction). The guide seat 14 is provided with at least two guide sliding blocks 16, and the adjacent two guide sliding blocks 16 form the vertical sliding groove 15. The rack 1 is provided with a horizontal guide groove 17 arranged along the horizontal axis direction, and the guide sliding blocks 16 are slidably installed in the horizontal guide groove 17, so as to realize the moving away or close to of the blade driving wheel 8 of the rack 1 relative to the reversing wheel 7.

[0064] In some embodiments, the height adjustment mechanism 11 is configured to adjust the height of the floating cutter head 5 as a whole, so that the floating cutter head 5 has an adjusted high position and an adjusted low position. The height adjustment mechanism 11 includes a driving member 1101 hingedly connected to the rack 1, and the floating cutter head 5 is hingedly installed at the bottom of the rack 1 through first and second connecting rods 1102 and 1103. The driving member 1101 is hingedly connected to the first connecting rod 1102 through a first driving rod 1104 eccentrically arranged, and is hingedly connected to the second connecting rod 1103 through a second driving rod 1105 eccentrically arranged. Figure 13 As shown in the figure, the first driving rod 1104 and the second driving rod 1105 are eccentrically hingedly connected to the driving member 1101, and the two driving rods are connected to the first and second connecting rods 1102 and 1103. The second connecting rod 1103 is triangular, and the first connecting rod 1102 is hingedly connected to the floating cutter head 5 and the first driving rod 1104 at the same time. By swinging the driving member 1101, the first and second driving rods 1104 and 1105 are swung, so as to realize the upward or downward swing of the floating cutter head 5.

[0065] Specifically,Figure 3 is a schematic view of the floating cutterhead 5 in the raised position, Figure 13 is a schematic view of the floating cutterhead 5 in the lowered position.

[0066] In an example, as shown in Figure 1 , Figure 3 and Figure 13 , the height adjustment mechanism 11 is achieved by manual adjustment, as shown in Figure 1 and Figure 20 , an adjusting rod is fixedly installed on the driving member 1101, and a gear seat with multiple gear slots is correspondingly installed on the frame 1.

[0067] In some embodiments, as shown in Figure 19 , the floating cutterhead 5 is provided at the bottom with a mowing cavity 502 for accommodating the blade 501, and a connecting seat 503 connected with the blade 501 and the blade driving wheel 8 is installed in the floating cutterhead 5. The synchronous belt 9 is provided with a fixed tension pulley 504 and a floating tension pulley 505 on the side close to the blade driving wheel 8.

[0068] It should be noted that the contact of the fixed tension pulley 504 and the floating tension pulley 505 with the synchronous belt 9 is also a surface contact, which not only plays a tensioning role, but also can guide the synchronous belt 9 to better mesh with the blade driving wheel 8.

[0069] Specifically, as shown in Figure 5 , Figure 6 and Figure 19 , the connecting seat 503 is hingedly installed with a floating hinge rod 506 for installing the floating tension pulley 505; a connecting frame 101 is installed on the frame 1, and a spring 507 is installed between the floating hinge rod 506 and the connecting frame 101; a guide vane 801 is provided on the blade driving wheel 8, and a corresponding guide groove 508 is provided through the floating cutterhead 5, and a heat dissipation vane 401 is provided on the clutch driving wheel 4 for heat dissipation of the electromagnetic clutch 3.

[0070] It should be noted that the guide vane 801 has a different function from the prior art, which is used to assist in blowing air into the mowing cavity 502 through the guide groove 508, ensuring the amount of air entering the mowing cavity 502, so that the grass clippings in the mowing cavity 502 can be better pumped to the external grass collecting box 12; the floating cutterhead 5 is connected to the grass collecting box 12 through the connecting pipe 6, and in combination with Figure 5 and Figure 19 , the upper curved blade structure at the end of the blade 501 still plays the role of "blower", which can send the grass clippings to the connecting pipe 6 while running at high speed, and finally into the grass collecting box 12.

[0071] In some embodiments, in combination with Figures 15-20The grass collection box 12 is rotatably mounted on the front end of the frame 1. The grass collection box 12 includes a box body 1201. A discharge cover 1203 is rotatably mounted on the discharge window 1202 of the box body 1201. A hinge seat 102 is provided on the frame 1, which is movably hinged to the box body 1201. A control rod 1204 is also eccentrically hinged to the hinge seat 102. The other end of the control rod 1204 is hinged to the discharge cover 1203. When the entire grass collection box 12 is rotatably rotated, causing the discharge window 1202 to tilt downwards, the rotation of the box body 1201 drives the control rod 1204 to rotate, simultaneously opening the discharge cover 1203 for automatic dumping of chopped grass and waste. Figure 18 and Figure 20 After the container 1201 is flipped over, its unloading window 1202 will automatically open and tilt towards the setting, making the dumping of straw and garbage convenient.

[0072] In one example, such as Figure 18 As shown, the control lever 1204 is hinged to the inside of the unloading cover 1203, making it safe to use and less likely to be accidentally touched.

[0073] In some embodiments, the hinge seat 102 is positioned higher than the bottom of the housing 1201 (it can also be repositioned by the self-realignment of the housing 1201 during reset, saving effort). The hinge seat 102 is also eccentrically hinged to a pneumatic spring 1209 (the pneumatic spring is a standard part, with the same structure as the pneumatic spring used in existing car trunks, etc.). The upper end of the housing 1201 is provided with a handle 1205 and a viewing window 1206. Both the housing 1201 and the unloading cover 1203 are provided with through grid holes 1207. The floating cutter head 5 is connected to the inner cavity of the housing 1201 through a connecting pipe 6. The connecting pipe 6 is detachably installed on the mounting notch 1208 of the housing 1201.

[0074] like Figure 20 As shown, in one example, the connecting pipe 6 needs to be removed from the housing 1201 before the housing 1201 can be flipped. Of course, by using a more flexible telescopic pipe, the housing 1201 can be flipped without removing the connecting pipe 6. The goal is simply to achieve the smooth flipping of the housing 1201.

[0075] like Figure 15 and Figure 18 As shown, the handle 1205 is located at the upper end of the housing 1201 away from the hinge seat 102, and utilizes the lever principle to enable flipping operation.

[0076] The same or similar parts between the various embodiments in this specification can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments.

[0077] The above merely provides the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any changes or replacements within the technical scope disclosed by the present application can be easily conceived by the person skilled in the art, and should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
