Specific implementation

[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor fall within the protection scope of the utility model.

[0023] In combination with the drawings, Figures 1-5 The utility model provides a kind of green belt weeding protection device, including fixed rod 1, fixed rod 1 can provide mobile support for entire green belt weeding protection device, fixed rod 1 is rotatably connected with cutter head 2, fixed rod 1 is provided with the weeding driving device 3 for driving cutter head 2 rotation, the bottom of cutter head 2 is provided with multiple convex seats 4, each convex seat 4 is provided with buffer rotating assembly 5.

[0024] The middle part of cutter head 2 is fixedly connected with rotating sleeve 8, and cutter head 2 is rotatably connected to fixed rod 1 by rotating sleeve 8, weeding driving device 3 includes weeding motor 31 fixedly connected to fixed rod 1, gear one 32 fixedly connected to the output end of weeding motor 31 and gear two 33 meshingly connected on gear one 32, and gear two 33 is fixedly connected to rotating sleeve 8.

[0025] Specifically, in the fixed rod 1 position is in the state of fixed traction, by external power supply and controller to control the rotation of the motor 31 output, gear one 32 and gear two 33 meshing can make the cutter head 2 on the fixed rod 1 rotation, so that the cutter head 2 on the cutter can rotate, in order to weed cutting.

[0026] The fixed rod 1 is fixedly connected with the protective cover 12, the protective cover 12 is arranged outside the gear one 32 and the gear two 33, and the above-mentioned weed motor 31 can be fixed on the protective cover 12, and the output end of the weed motor 31 can extend into the protective cover 12 to connect the gear one 32. The protective cover 12 is arranged to shield and protect the transmission area of the gear one 32 and the gear two 33.

[0027] The buffer rotating assembly 5 is detachably connected with the weeding blade 6, and the weeding blade 6 can be arranged on the cutter head 2 by rotating the buffer rotating assembly 5, so that the weeding blade 6 can be thrown out for use when the cutter head 2 rotates. The upper and lower surfaces of the weeding blade 6 are fixedly connected with the buffer comb plate 7, and the side surface of the buffer comb plate 7 is arranged beyond the position of the blade edge of the weeding blade 6. In the present application, the buffer comb plate 7 can be made of hard rubber, which can buffer and protect the blade edge of the weeding blade 6.

[0028] The buffer rotating assembly 5 comprises a rotating rod 51 rotatably connected to the bottom of the convex base 4, a ball seat 52 fixedly connected to the bottom end of the rotating rod 51, and a ball one 53 ball rotatably connected to the side surface of the ball seat 52. The ball one 53 is fixedly connected with the assembly rod 10, and the weeding blade 6 is detachably connected with the assembly rod 10 by fasteners. The arrangement of the convex base 4 can expand the avoiding range of the rotation of the weeding blade 6. In the present application, the assembly rod 10 is provided with a blade groove matched with the size of the weeding blade 6. By arranging the weeding blade 6 in the blade groove, the weeding blade 6 can be assembled by using fasteners such as bolts.

[0029] Specifically, when the cutter head 2 rotates to drive the weeding blade 6 to throw out for weeding, if the weeding blade 6 is impacted by a hard object, the impact force can be unloaded by the rotation of the ball one 53 on the ball seat 52 and the rotation of the ball seat 52 on the convex base 4. Since the rotation of the ball one 53 and the ball seat 52 and the rotation of the ball seat 52 on the convex base 4 have multiple angles, the weeding blade 6 can rotate and unload the force in multiple angles when impacted by a hard object in different directions. In combination with the buffer comb plate 7 made of rubber, the strength of the impact of the weeding blade 6 on the hard object can be maximized, thereby improving the durability of the weeding blade 6 and avoiding the damage to the personnel caused by the impact and breakage of the weeding blade 6.

[0030] The bottom of the ball seat 52 is ball rotatably connected with a ball two 9. The ball two 9 is arranged to provide ball rotation support for the ball seat 52, so as to provide rolling support for the cutter head 2 when moving on the ground for weeding. Thus, the labor intensity of manually holding the green belt weeding protection device to lift can be reduced.

[0031] The buffer comb plate 7 is provided with a plurality of notches 71. The blade of the weeding blade 6 exceeds the end position of the notch 71 on the buffer comb plate 7, and the blade of the weeding blade 6 does not exceed the head end of the notch 71. The notch 71 is arranged to facilitate the entry of the grass so that the blade of the weeding blade 6 can cut the grass. In this application, a plurality of buffer comb plates 7 are arranged. Therefore, the notches 71 on each buffer comb plate 7 should be arranged staggered. In this way, the weeding blade 6 can completely cut the weeding area.

[0032] The fixed rod 1 is fixedly connected with a fixed sleeve 11. The fixed sleeve 11 is also provided with a fastener, which can be assembled and connected with the handheld rod. Alternatively, the fixed rod 1 can be directly connected with the mobile device, so that the spherical body two 9 can not be used as a mobile support. The bottom end of the fixed rod 1 is provided with a lighting lamp 13. The lighting lamp 13 can be controlled by an external power supply and a controller. The lighting lamp 13 can provide lighting for the weeding area, so that the greening belt weeding protection device can be more clear during the weeding process at night.
