[0022] Embodiment 1:

[0023] In this embodiment, Figure 1 and Figure 2 As shown, an oil-electric hybrid remote-controlled grass shredder includes a walking frame 1, an engine 2, a battery 3, a knife barrel 4, a generator 5 and a remote-controlled depth adjustment mechanism 6. The engine 2, the generator 5 and the battery 3 are all installed on the walking frame 1, the knife barrel 4 is installed on the walking frame 1 through the remote-controlled depth adjustment mechanism 6, the power output end of the engine 2 is respectively connected to the knife barrel 4 and the generator 5, the generator 5 is electrically connected to the battery 3, and the battery 3 is respectively electrically connected to the walking mechanism of the walking frame 1 and the control end of the remote-controlled depth adjustment mechanism 6.

[0024] The lawn mower is powered by a fuel engine 2, which drives the rotation of the knife drum 4 to weed. At the same time, another part of the power of the engine 2 is output to the generator 5, which is converted into electrical energy and stored in the battery 3. The battery 3 provides power to the walking mechanism of the walking frame 1 and the control end of the remote control depth adjustment mechanism 6. When it is necessary to change the weeding depth of the knife drum 3, it is only necessary to remotely control the remote control depth adjustment mechanism 6 to change the height of the knife drum 4 relative to the walking frame 1. The operation is simple, fast and highly automated.

[0025] Preferably, the remote-controlled depth adjustment mechanism 6 includes a remote-controlled electric push rod 7, a depth limiting wheel 8, a support rod 9 and a sliding sleeve 10. The remote-controlled electric push rod 7 is installed on the walking frame 1. One end of the support rod 9 is rotatably connected to the telescopic end of the remote-controlled electric push rod 7. The depth limiting wheel 8 is rotatably installed on the other end of the support rod 9. The sliding sleeve 10 is slidably installed on the support rod 9. The sliding sleeve 10 is rotatably connected to the knife cylinder 4, and the knife cylinder 4 is slidably connected to the walking frame 1.

[0026] The operation of the remote control electric push rod 7 is controlled by a remote controller to make the push rod do telescopic movement. When it is extended, the support rod 9 is lifted upward, and the sliding sleeve 10 slides along the support rod 9 to the higher end. At the same time, the knife cylinder 4 also moves upward on the walking frame 1, thereby achieving the purpose of adjusting the knife cylinder 4, otherwise the height of the knife cylinder 4 is reduced.

[0027] Preferably, the moving direction of the knife cylinder 4 and the moving direction of the sliding sleeve 10 are not in the same direction.

[0028] The moving direction of the knife cylinder 4 and the moving direction of the sliding sleeve 10 form an angle less than 180°.

[0031] Preferably, a manual adjustment screw 12 is provided between the support rod 9 and the depth limiting wheel 8 .

[0032] When the remote control electric push rod 7 fails or malfunctions, the height of the support rod 9 relative to the depth limiting wheel 8 can be adjusted by manually adjusting the screw rod 12, thereby achieving the purpose of adjusting the height of the knife barrel 4.

[0033] Preferably, the walking mechanism is a crawler track.

[0034] The working process of the utility model is as follows: the lawn mower is provided with total power by the fuel engine 2, which drives the rotation of the knife drum 4 to weed. At the same time, another part of the power of the engine 2 is output to the generator 5 and converted into electrical energy and stored in the battery 3. The battery 3 provides power to the walking mechanism of the walking frame 1 and the control end of the remote control depth adjustment mechanism 6. When it is necessary to change the weeding depth of the knife drum 3, it is only necessary to remotely control the operation of the remote control electric push rod 7 through the remote control to make the push rod do telescopic movement. When it is extended, the support rod 9 is lifted upward, and the sliding sleeve 10 slides along the support rod 9 to the higher end. At the same time, the knife drum 4 also moves upward on the walking frame 1, thereby achieving the purpose of adjusting the knife drum 4, and vice versa, the height of the knife drum 4 is reduced.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
