The free end of the driving rod 46 is rotatably connected to the rake 43, and a gear 3 47 meshing with the gear 2 45 is rotatably connected to the surface of the carrier plate 31.

[0034] Among them, gear three 47 is driven by an external motor; With the above solution, when the staff pulls the base 1 and walks slowly, the staff should walk backwards at this time, and the rake 43 can rake the trimmed grass or some dead branches and leaves on the ground to a preset position for subsequent processing.

[0035] When the rectangular rod 36, the long rod 37 and the U-shaped seat 38 are Figure 1 and Figure 2 In the vertical state shown, the gear 1 314 rotates clockwise, and the gear 1 314 gradually meshes with the first arc-shaped rack 316, so that the gear 1 314 can drive the worm 313 coaxially fixed thereto to rotate, and the worm 313 can drive the worm wheel 311 meshing therewith to rotate, and the worm wheel 311 can drive the U-shaped seat 38 coaxially fixed thereto to rotate ninety degrees, so that the U-shaped seat 38 and the long rod 37 are in a vertical state, as shown in FIG. Figure 7 As shown, the blade 2 rotates at this time to trim the side of the green belt; When the long rod 37 and the rectangular rod 36 are inclined at different angles, the heights at which the blade 2 is located will be different; At the same time, the height of the blade 2 is also related to the length of the rectangular rod 36 and the long rod 37. When the rectangular rod 36 and the long rod 37 are tilted upward, the longer the length, the higher the position of the blade 2; An adjusting assembly for driving the long rod 37 to extend outward is arranged inside the rectangular rod 36 .

[0036] like Figure 7 and Figure 8 As shown, the adjustment assembly includes a first bevel gear 51 rotatably connected in the rectangular rod 36 and coaxially fixed with the sliding column 310, a vertical plate 52 is fixedly connected in the rectangular rod 36, a second bevel gear 53 meshing with the first bevel gear 51 is rotatably connected on the vertical plate 52, and a reciprocating threaded rod 54 coaxially fixed with the second bevel gear 53, a movable sleeve 55 is sleeved on the reciprocating threaded rod 54, a sliding block that is rotatably connected to the inner wall of the movable sleeve 55 and is compatible with the surface groove of the reciprocating threaded rod 54, and a cylindrical rod 56 is fixedly connected between the movable sleeve 55 and the long rod 37.

[0038] When the sliding column 310 moves along the semicircular movable groove 34, the arc-shaped clamping plate 57 on the sliding column 310 can be stuck in the limiting block 58. When the gear 2 45 rotates, the arc-shaped clamping plate 57 and the sliding column 310 can be driven to rotate through the limiting block 58, and the sliding column 310 can drive the first bevel gear 51 to rotate.

[0039] Among them, only when the length of the rectangular rod 36 and the long rod 37 needs to be adjusted, the arc-shaped clamping plate 57 on the sliding column 310 can be clamped in the limiting block 58; Alternatively, when the required height of the blade 2 makes the rectangular rod 36 and the long rod 37 in a horizontal state, the arc-shaped clamping plate 57 on the sliding column 310 is stuck in the limiting block 58, but when the blade 2 is working, the limiting block 58 may not rotate.

[0040] Among them, the blade 2 can be Figure 1 The circle in Fig.12 The bars in When the blade 2 is needed to trim the lawn or trim the side of the green belt, a circular blade 2 is used; When the top of the green belt needs to be trimmed, a strip-shaped blade 2 is used; The circular blade 2 and the strip blade 2 can be detachably mounted on the U-shaped seat 38 for easy replacement.

[0041] The working principle and use process of the present invention: The bar frame 39 is driven to rotate by an external motor. As the bar frame 39 rotates, the sliding column 310 can be pushed to move in the vertical groove 1 32, the semicircular movable groove 34 and the vertical groove 2 33; When the sliding column 310 is located at the connection point between the semicircular movable groove 34 and the vertical groove 1 32, the rectangular rod 36 and the long rod 37 are in a vertical state, and the blade 2 is close to the ground and parallel to the ground. The blade 2 can trim the lawn when rotating, and the staff needs to push the base 1 to move on the lawn; When the sliding column 310 moves up and down in the vertical groove 1 32, it can drive the rectangular rod 36, the long rod 37, the U-shaped seat 38 and the blade 2 to move upward, thereby adjusting the distance between the blade 2 and the ground, thereby adjusting the length of the lawn mowing; When the rectangular rod 36, the long rod 37 and the U-shaped seat 38 are Figure 1 and Figure 2 In the vertical state shown, the gear 1 314 rotates clockwise, and the gear 1 314 gradually meshes with the first arc-shaped rack 316, so that the gear 1 314 can drive the worm 313 coaxially fixed thereto to rotate, and the worm 313 can drive the worm wheel 311 meshing therewith to rotate, and the worm wheel 311 can drive the U-shaped seat 38 coaxially fixed thereto to rotate ninety degrees, so that the U-shaped seat 38 and the long rod 37 are in a vertical state, as shown in FIG. Figure 7 As shown, the blade 2 rotates at this time to trim the side of the green belt, and the staff also needs to push the base 1 to move; When the long rod 37 and the rectangular rod 36 are inclined at different angles, the heights at which the blade 2 is located will be different; At the same time, the height of the blade 2 is also related to the total length of the rectangular rod 36 and the long rod 37. When the rectangular rod 36 and the long rod 37 are tilted upward, the longer the long rod 37 extends, the higher the position of the blade 2 is. When the sliding column 310 moves along the semicircular movable groove 34, the arc-shaped clamping plate 57 on the sliding column 310 can be stuck in the limiting block 58. When the gear 2 45 rotates, the arc-shaped clamping plate 57 and the sliding column 310 can be driven to rotate therewith through the limiting block 58. The sliding column 310 can drive the first bevel gear 51 to rotate therewith, and the first bevel gear 51 can drive the second bevel gear 53 meshing therewith to rotate therewith. The second bevel gear 53 can drive the reciprocating threaded rod 54 to rotate therewith, and the reciprocating threaded rod 54 can drive the movable sleeve 55 to move along the rectangular rod 36. The movable sleeve 55 can drive the long rod 37 to move therewith through the cylindrical rod 56, so that the long rod 37 extends to the outside of the rectangular rod 36, so that the working range of the blade 2 is increased; When the rectangular rod 36, the long rod 37 and the U-shaped seat 38 are Figure 7 If the worm 313 is rotated clockwise in the vertical state shown, the gear 1 314 will gradually mesh with the second arc-shaped rack 317, so that the gear 1 314 drives the worm 313 to rotate, and the worm 313 drives the worm wheel 311 to rotate. The worm wheel 311 can drive the U-shaped seat 38 coaxially fixed thereto to rotate ninety degrees, so that the U-shaped seat 38 and the long rod 37 are in the same straight line. Fig.12 and Fig.13 As shown, the circular blade 2 can be replaced with a strip blade 2 to facilitate trimming the top of the green belt; When the sliding column 310 moves up and down in the second vertical slot 33, it can drive the rectangular rod 36, the long rod 37, the U-shaped seat 38 and the blade 2 to move upward, thereby adjusting the overall height of the blade 2 to adapt to green belts of different heights; When the lawn is mowed, the external motor drives the gear three 47 to rotate, and the gear three 47 can drive the gear two 45 meshing with it to rotate, and the gear two 45 can drive the driving rod 46 to rotate, and the driving rod 46 can drive the rake 43 to swing when rotating, so that the rake 43 can not only swing up and down with the hinge point between it and the vertical rod 42 as the center of the circle, but also allow the vertical rod 42 to move in the horizontal direction, so that the moving trajectory of the end of the vertical rod 42 is circular, so that the weeds and other debris on the ground are raked away.
