[0005] An anti-collision lawn mower with high safety includes a lawn mower. A protection frame is fixedly installed on the front side of the lawn mower. Two hydraulic telescopic rods are fixedly installed on the lawn mower, and the two hydraulic telescopic rods are of the same source. A plug board is vertically inserted into the lawn mower. The output end of the hydraulic telescopic rod is fixedly connected to the top of the plug board. A plurality of horizontal pipes and horizontal cylinders are fixedly installed on one side of the plug board. A cross bar is movably inserted into the horizontal pipe, and a plug column is movably inserted into the horizontal cylinder. A spring is arranged between the inner wall of one side of the horizontal cylinder and one end of the plug column. The cross bar and the plug column are jointly fixedly installed with a mounting plate. A plurality of vertical rods are arranged on the mounting plate. The vertical rods can be controlled to descend through the hydraulic telescopic rods. The grass on the ground can enter below the lawn mower between the vertical rods. The bottom ends of the vertical rods can contact the stones earlier than the grass cutting tool, so as to avoid the stones hitting the tool.

[0006] Preferably, the top of the vertical rod penetrates through the mounting plate, and a nut is installed on the top of the mounting plate through threads, so that the vertical rod can be disassembled and assembled for easy replacement.

[0007] Preferably, a bottom block is fixedly installed at the bottom of the vertical rod. The bottom block is spherical, and the contact between the bottom block and the stone is smoother, which can better ensure the stability of the vertical rod.

[0008] Preferably, a vertical plate is arranged in the protection frame. One side of the vertical plate contacts the vertical rod. A plurality of convex blocks are fixedly installed on the other side of the vertical plate. The convex blocks penetrate through one side of the protection frame. The convex blocks can collide with obstacles, and the spring can buffer to ensure the overall stability.

[0009] Preferably, two side openings are symmetrically formed on both sides of the protection frame, a guiding column is horizontally and fixedly installed in each side opening, two vertical plates are slidably installed in the side openings, and the guiding column penetrates through the vertical plates to guide the vertical plates.

[0010] In summary, the utility model includes the following beneficial technical effects:

[0011] 1. Start the two hydraulic expansion rods to lower the insertion plate, and the vertical rod also descends accordingly. The bottom block approaches the ground. When the lawn mower encounters a stone, the bottom block can directly contact the stone, avoiding the stone from directly colliding with the cutter. The insertion post is inserted into the transverse cylinder and can be buffered when the bottom block contacts the stone to protect the vertical rod. The vertical rod is fixedly installed on the mounting plate through a nut and can be conveniently replaced;

[0012] 2. When the whole lawn mower moves forward and collides with an obstacle, the obstacle can contact the convex block. The convex block is fixed on the vertical plate, the vertical plate contacts the vertical rod, and the guiding column penetrates through the vertical plate for guiding. The spring can also buffer the convex block, and the whole is stable during the collision. Description of the Drawings

[0019] An embodiment of the utility model discloses a collision - proof lawn mower with high safety.

[0020] A collision - proof lawn mower with high safety includes a lawn mower 1. A protective frame 2 is fixedly installed on the front side of the lawn mower 1. There are two hydraulic telescopic rods 22 fixedly installed on the lawn mower 1, and the two hydraulic telescopic rods 22 are of the same source. A plug board 21 is vertically inserted into the lawn mower 1. The output end of the hydraulic telescopic rod 22 is fixedly connected to the top of the plug board 21. A plurality of horizontal pipes 25 and horizontal cylinders 23 are fixedly installed on one side of the plug board 21. A cross bar 26 is movably inserted into the horizontal pipe 25. A plug post 29 is movably inserted into the horizontal cylinder 23. A spring 210 is arranged between one inner wall of the horizontal cylinder 23 and one end of the plug post 29. The cross bar 26 and the plug post 29 are jointly fixedly installed on a mounting plate 27. A plurality of vertical rods 24 are arranged on the mounting plate 27. The vertical rods 24 can be controlled to descend through the hydraulic telescopic rods 22. The grass on the ground can enter below the lawn mower 1 from between the vertical rods 24. The bottom ends of the vertical rods 24 can contact the stones earlier than the grass - cutting tool, which can avoid the stones hitting the tool.

[0021] In Figure 1 and Figure 3 : The top of the vertical rod 24 penetrates through the mounting plate 27, and a nut is installed on the top of the mounting plate 27 by threads, which can disassemble and assemble the vertical rod 24 for easy replacement. A bottom block 28 is fixedly installed at the bottom of the vertical rod 24. The bottom block 28 is spherical. The contact between the bottom block 28 and the stone is smoother, which can better ensure the stability of the vertical rod 24.

[0022] In Figure 1 and Figure 2 : A vertical plate 32 is arranged inside the protective frame 2. One side of the vertical plate 32 contacts the vertical rod 24. A plurality of convex blocks 33 are fixedly installed on the other side of the vertical plate 32. The convex blocks 33 penetrate through one side of the protective frame 2. The convex blocks 33 can collide with obstacles, and the spring 210 can buffer to ensure the overall stability. Two side ports 3 are symmetrically opened on both sides of the protective frame 2. A guiding column 31 is horizontally fixedly installed inside the side port 3. Two vertical plates 32 are slidably installed inside the side port 3, and the guiding column 31 penetrates through the vertical plate 32 to guide the vertical plate 32.

[0023] The standard parts used in the utility model can all be purchased from the market. The special - shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding in the existing technology. The machines, parts, and equipment all adopt conventional models in the existing technology. Coupled with the circuit connection adopting the conventional connection method in the existing technology, details are not described here.

[0024] The implementation principle of a collision-proof lawn mower with high safety in the embodiment of the present utility model is as follows: The lawn mower 1 can mow grass on relatively flat ground. The cutter of the lawn mower 1 is arranged at the bottom and the whole is movable. When encountering uneven ground with protruding stones, two hydraulic expansion rods 22 are activated to lower the plug board 21, and the vertical rod 24 also descends accordingly. The bottom block 28 is close to the ground. When the lawn mower 1 moves and encounters a stone, the bottom block 28 directly contacts the stone, which can prevent the stone from directly colliding with the cutter. The plug post 29 is inserted into the horizontal cylinder 23, and a spring 210 is used for buffering when the bottom block 28 contacts the stone to protect the vertical rod 24. The vertical rod 24 is fixedly installed on the mounting plate 27 through nuts and can be conveniently replaced; when the whole lawn mower 1 moves forward and collides with an obstacle, the obstacle can contact the convex block 33. The convex block 33 is fixed on the vertical plate 32. The vertical plate 32 contacts the vertical rod 24, and the guide post 31 penetrates through the vertical plate 32 for guiding. The spring 210 can also buffer the convex block 33 to keep the whole stable during the collision.
