[0026] The first embodiment of the present application is:

[0027] Please refer to Figures 1-5 , where Figure 1 is the overall structural schematic diagram of the first embodiment of the present invention, Figure 2 is the bottom view of the first embodiment of the present invention, Figure 3 is the bottom view of the first embodiment of the present invention, Figure 4 is the Figure 3 A-A line cross-sectional view of the present invention, Figure 5 is the Figure 4 local enlarged structural view at B of the present invention.

[0028] The present invention provides an obstacle-avoiding lawn mower and system, including a mobile trolley 101 and a weeding mechanism 102. The weeding mechanism 102 includes a plurality of wheels 103, a push frame 104, an anti-slip sleeve 105, a lifting assembly 106, two protective assemblies 107, a mounting assembly 108 and a weeding assembly 109. The lifting assembly 106 includes side plates 110, two lifting cylinders 111, sliding rods 112 and a lifting frame 113. Each protective assembly 107 includes a column 114 and an arc plate 115. The mounting assembly 108 includes a mounting disc 116, an anti-disengagement ring 117 and a rubber ring 118. The weeding assembly 109 includes a weeding motor 119, a turntable 120, a plurality of blades 121 and a plurality of abutting wheels 122.

[0029] For this specific embodiment, the weeding assembly 109 is fixedly connected to the lifting assembly 106, the mounting assembly 108 is rotatably connected to the weeding assembly 109, both protective assemblies 107 are fixedly connected to the lifting assembly 106, the lifting assembly 106 is fixedly connected to the mobile trolley 101, the protective sleeve is fixedly connected to the push frame 104, the push frame 104 is fixedly connected to the mobile trolley 101, each wheel 103 is rotatably connected to the mobile trolley 101, the lifting frame 113 is fixedly connected to the output ends of the two lifting cylinders 111, the sliding rod 112 is fixedly connected to the side plate 110, both lifting cylinders 111 are fixedly connected to the side plate 110, the side plate 110 is fixedly connected to the mobile trolley 101, the arc plate 115 is rotatably connected to the column 114, the column 114 is fixedly connected to the lifting frame 113, the rubber ring 118 is fixedly connected to the mounting disc 116, the anti-disengagement ring 117 is fixedly connected to the mounting disc 116, the mounting disc 116 is fixedly connected to the lifting frame 113, each abutting wheel 122 is rotatably connected to the turntable 120, each blade 121 is fixedly connected to the turntable 120, the turntable 120 is fixedly connected to the output end of the weeding motor 119, the weeding motor 119 is fixedly connected to the lifting frame 113. The two lifting cylinders 111 in the currently provided lifting assembly 106 can adjust the height of the lifting frame 113 according to the control of the staff, and further adjust the height between the turntable 120 and the blades 121 in the weeding assembly 109 and the ground, so as to adapt to the grass cutting environment in real time. And the arc plate 115 with an adjustable deflection angle in the protective assembly 107 protects the mounting disc 116. Without affecting the normal weeding operation, this design solves the problem that the lawn mower under the chassis cannot adjust the height from the ground during the weeding operation, and the cutting effect on weeds is limited when the weed heights are inconsistent.

[0030] Among them, the weeding component 109 is located on one side of the lifting component 106, the mounting component 108 is located on the periphery of the weeding component 109, the two protective components 107 are respectively located on both sides of the lifting component 106, the lifting component 106 is located on one side of the mobile trolley 101, the protective sleeve is located above the push frame 104, the push frame 104 is located above the mobile trolley 101, and each wheel 103 is respectively located on both sides of the mobile trolley 101. When the turntable 120 is driven to rotate by the weeding motor 119, the anti-detachment ring 117 inside the mounting plate 116 limits the periphery of the turntable 120, which can prevent the turntable 120 from detaching from the inside of the mounting plate 116, enhancing the overall structural strength of the device.

[0031] Secondly, the sliding rod 112 is located below the side plate 110, the two lifting cylinders 111 are both located above the side plate 110, the side plate 110 is located on one side of the mobile trolley 101, the arc plate 115 is located on one side of the column 114, the column 114 is located below the lifting frame 113, and the rubber ring 118 provided on the periphery of the mounting plate 116 can protect the mounting plate 116. When there are small stones on the forward movement track of the mobile trolley 101, the stones can be knocked away to prevent the blade 121 from contacting the stones. The setting of multiple abutting wheels 122 below the turntable 120 also limits the descending height of the turntable 120, preventing the turntable 120 from directly contacting the ground, reducing the mowing efficiency and shortening the service life of the blade 121 at the same time. The staff manually pushes the push frame 104 to drive the mobile trolley 101 to move. Since each wheel 103 can rotate and turn freely, the operation difficulty of the staff is simple, and only the height change of the lifting frame 113 needs to be adjusted by controlling the two lifting cylinders 111, and the efficiency of cutting weeds is high.

[0032] Meanwhile, the rubber ring 118 is located on the peripheral side of the mounting disc 116, the anti - detachment ring 117 is located inside the mounting disc 116, the mounting disc 116 is located below the lifting frame 113, each abutting wheel 122 is located below the turntable 120, each blade 121 is located below the turntable 120, the weeding motor 119 is located above the lifting frame 113, the blade 121 rotates around the mounting shaft under the turntable 120 driven by the weeding motor 119. After the weeding motor 119 is started, the staff manually adjusts the rotation angle of the arc - shaped plate 115. While the arc - shaped plate 115 plays a protective role on the peripheral side of the mounting disc 116, it can also collect and gather the weeds in front of the moving track of the mobile cart 101 for the blade 121 inside the turntable 120 to cut. Similarly, the two lifting cylinders 111 can adjust the height of the lifting frame 113 at any time to avoid large - sized stones, or further lower the height of the lifting frame 113 to make the blade 121 fit the ground more closely for deep cutting of the weeds.

[0033] In this embodiment, when the turntable 120 is driven to rotate by the weeding motor 119, the circumferential side of the turntable 120 is limited by the anti - detachment ring 117 inside the mounting plate 116, which can prevent the turntable 120 from detaching from the inside of the mounting plate 116, enhancing the overall structural strength of the device. The rubber ring 118 arranged on the circumferential side of the mounting plate 116 can protect the mounting plate 116. When there are small stones on the forward movement trajectory of the mobile cart 101, the stones can be knocked away to prevent the blade 121 from contacting the stones. The arrangement of multiple abutting wheels 122 below the turntable 120 also limits the descending height of the turntable 120, preventing the turntable 120 from directly contacting the ground, reducing the mowing efficiency and shortening the service life of the blade 121 at the same time. The staff manually pushes the push frame 104 to drive the mobile cart 101 to move. Since each wheel 103 can freely rotate and turn, the operation difficulty for the staff is simple. They only need to adjust and control the height change of the lifting frame 113 by two lifting cylinders 111. The efficiency of cutting weeds is high. The blade 121 rotates around the mounting shaft under the turntable 120 driven by the weeding motor 119. After the weeding motor 119 is started, the staff manually adjusts the rotation angle of the arc plate 115. While the arc plate 115 plays a protective role on the circumferential side of the mounting plate 116, it can also collect and gather the weeds in front of the movement trajectory of the mobile cart 101 for the blade 121 inside the turntable 120 to cut. Similarly, the two lifting cylinders 111 can adjust the height of the lifting frame 113 at any time to avoid large - sized stones, or further lower the height of the lifting frame 113 to make the blade 121 fit more closely to the ground for deep cutting of weeds.

[0037] For this specific embodiment, the limit frame 204 is fixedly connected to the mobile trolley 101 and is located at the inner bottom of the mobile trolley 101. Each hoe 203 is fixedly connected to the soil loosening plate 202 and is located below the soil loosening plate 202. The soil loosening plate 202 is fixedly connected to the output end of the soil loosening cylinder 201. The soil loosening cylinder 201 is fixedly connected to the mobile trolley 101 and is located on the inner top wall of the mobile trolley 101. After the multiple blades 121 inside the mounting plate 116 cut the weeds in the grassland, according to the actual usage situation, the soil loosening cylinder 201 can be started to lower the height of the soil loosening plate 202 and each hoe 203, and the ground after cutting is loosened, further enhancing the practical function of the device and saving the subsequent investment in manpower. It should be noted that both the front and rear sides of each hoe 203 are hollow, and the soil directly passes over the corresponding hoe 203 after being loosened and will not accumulate at the bottom of the mobile trolley 101.

[0038] In this embodiment, after the multiple blades 121 inside the mounting plate 116 cut the weeds in the grassland, according to the actual usage situation, the soil loosening cylinder 201 can be started to lower the height of the soil loosening plate 202 and each hoe 203, and the ground after cutting is loosened, further enhancing the practical function of the device and saving the subsequent investment in manpower. It should be noted that both the front and rear sides of each hoe 203 are hollow, and the soil directly passes over the corresponding hoe 203 after being loosened and will not accumulate at the bottom of the mobile trolley 101.
