Therefore, an electric lawn mower that can adjust the direction and whose interior is not blocked by weeds and dust is designed. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an electric lawn mower, which solves the problems raised in the above background technique.

[0006] To achieve the above objectives, the present utility model is realized through the following technical solutions: An electric lawn mower includes a motor and a support rod, and also includes an adjustment device and a vibration device: Among them, the adjustment device includes a mudguard, a saw blade, a U-shaped plate, a grip, a handle, a connecting block, a connecting rod, an L-shaped connecting plate, and an L-shaped pushing plate. The mudguard is fixedly installed on the outer wall of the motor, the saw blade is fixedly installed at the output end of the motor, the U-shaped plate is fixedly installed on the outer wall of the motor, the grip is fixedly installed on the circumferential surface of the support rod, the handle is fixedly installed on the circumferential surface of the support rod, the connecting block is fixedly installed above the motor, the connecting rod is rotatably installed inside the connecting block, the L-shaped connecting plate is rotatably installed at the end of the connecting rod away from the connecting block, the L-shaped pushing plate is rotatably installed at the end of the connecting rod away from the connecting block, the L-shaped pushing plate slidably penetrates the inner and outer walls of the grip. Moving the L-shaped pushing plate upward releases the limit on the L-shaped connecting plate. After the limit is released, move the L-shaped connecting plate. The movement of the L-shaped connecting plate drives the connecting rod to rotate, the rotation of the connecting rod drives the connecting block to rotate, the rotation of the connecting block drives the motor to rotate, and the rotation of the motor drives the saw blade to rotate, realizing the adjustment of the saw blade angle to adapt to different terrains, improving the adaptability of the equipment, and solving the working difficulty and intensity of workers.

[0007] According to the above technical solution, a notch one is opened inside the grip, a notch two is opened inside the L-shaped connecting plate, and the U-shaped plate rotatably penetrates the inner and outer walls of the support rod. Re-connect the L-shaped pushing plate with the L-shaped connecting plate and fix it, so that the saw blade does not shake when not working, which may cause the saw blade to directly contact the ground and be damaged, reducing the potential safety hazards during the use of the equipment and reducing the subsequent maintenance cost.

[0008] According to the above technical solution, the vibration device includes a baffle, a telescopic spring rod, a convex plate, and a convex block. The baffle is fixedly installed inside the notch one, the telescopic spring rod is fixedly installed above the baffle, the convex plate is fixedly installed at the free end of the telescopic spring rod, and the convex block is fixedly installed below the L-shaped connecting plate. When the L-shaped connecting plate moves, it drives the convex block to move, and the convex block below the L-shaped connecting plate moves.

[0009] According to the above technical solution, one end of the convex plate close to the L-shaped pushing plate is set as a first arc surface, and one end of the convex block close to the convex plate is a second arc surface. The convex block and the convex plate collide and squeeze, the telescopic end of the telescopic spring rod below the convex plate contracts, and then the telescopic end of the telescopic spring rod resets to push the convex plate to repeatedly squeeze with the convex block to generate vibration. The vibration can effectively discharge the dust and soil inside the notch two, prevent the notch two from being blocked, which may affect the fixation of the L-shaped connecting plate, further increase potential safety hazards, and effectively reduce the subsequent maintenance cost.

[0010] The present utility model provides an electric lawn mower. It has the following beneficial effects:

[0011] (1) When the electric lawn mower is used for weeding on a slope, the rotation of the connecting rod can be driven by the movement of the L-shaped connecting plate. The rotation of the connecting rod drives the rotation of the connecting block, the rotation of the connecting block drives the rotation of the motor, and the rotation of the motor drives the rotation of the saw blade, realizing the adjustment of the angle of the saw blade to adapt to different terrains, improving the adaptability of the equipment, solving the working difficulty and intensity of workers. At the same time, after the adjustment is completed, the L-shaped push plate is re-contacted with the L-shaped connecting plate and fixed, so that the saw blade does not shake when it is not working, which may cause the saw blade to directly contact the ground and be damaged, reducing the potential safety hazards during the use of the equipment and the subsequent maintenance cost.

[0012] (2) When the L-shaped connecting plate moves, the convex block moves. The convex block below the L-shaped connecting plate moves, collides with and presses the convex plate, and the telescopic end of the telescopic spring rod below the convex plate contracts. Subsequently, the telescopic end of the telescopic spring rod resets and pushes the convex plate to repeatedly press against the convex block to generate vibration. The vibration can effectively discharge the dust and soil inside the second notch, preventing the notch from being blocked and affecting the fixation of the L-shaped connecting plate, thereby increasing potential safety hazards and effectively reducing the subsequent maintenance cost.
