[0036] The driving component 6 is connected to the connecting frame 2 through the mounting plate 61, and the main cutting knife 31 is connected to the output end of the driving component 6 through the rotating main shaft 32, so as to drive the rotating main shaft 32 to rotate through the driving component 6; further, the driving component 6 is connected to the rotating main shaft 32 through a coupling or a reducer;

[0037] The main transmission mechanism 7 has one end connected to the rotating main shaft 32, and the other end connected to the rotating secondary shaft 52 on the secondary cutting knife 51 in the secondary blade disc 5, so that the rotating main shaft 32 drives the main transmission mechanism 7 to rotate to drive the rotating secondary shaft 52 to rotate, thereby realizing that when the main cutting knife 31 rotates, the secondary cutting knife 51 rotates synchronously.

[0038] There are two auxiliary cutting knives 51 in this embodiment, and the two auxiliary cutting knives 51 are respectively located on both sides of the main cutting knife 31, and can rotate around the center of the main cutting knife 31 to adjust the angle between the two auxiliary cutting knives 51 and the main cutting knife 31, so as to adjust the lateral cutting length of the weeding device, and the two auxiliary cutting knives 51 can be formed into a V-shaped structure with the main cutting knife 31 through the swing arm 4, so as to facilitate the removal of weeds around the bottom of a single tree, and effectively improve the weeding efficiency of the weeding device.

[0039] Furthermore, the mobile body 1 of the present application is manually pushed and moved, and is provided with wheels for movement, and is also provided with a mounting surface for mounting and connecting the connecting frame 2.

[0040] As another embodiment of the present application, Figure 5As shown, the auxiliary cutting knives 51 of the present application are multiple, and are respectively arranged in the auxiliary blade disc 5; the multiple auxiliary cutting knives 51 are connected by the auxiliary transmission mechanism 8, and the auxiliary transmission mechanism 8 is located in the auxiliary blade disc 5. Further, in this embodiment, two auxiliary cutting knives 51 can be arranged in each auxiliary blade disc 5, and the two auxiliary cutting knives 51 in each auxiliary blade disc 5 are connected by the auxiliary transmission mechanism 8 to perform rotational cutting in the auxiliary blade disc 5.

[0041] See also Figure 7 The swing arm 4 of the present application includes a swing arm 1 41 and a swing arm 2 42, and the swing arm 1 41 and the swing arm 2 42 are rotatably arranged on the annular portion at the center of the main blade disc 3, and the auxiliary blade disc 5 is respectively fixed on the swing arm 1 41 and the swing arm 2 42, so that the two auxiliary blade discs 5 can be installed by setting the swing arm 1 41 and the swing arm 2 42, so that the two auxiliary blade discs 5 can rotate with the swing arm 1 41 and the swing arm 2 42 to adjust the lateral cutting length of the weeding device to adapt to the weeding work in wide and narrow row planting areas.

[0042] See also Figure 3 The synchronous swing mechanism 9 of the present application includes a driving motor 91, a first arc-shaped rack 92 and a second arc-shaped rack 93. The first arc-shaped rack 92 is fixedly arranged on the outer ring of the hinged end of the swing arm 1 41 so that the hinged end of the swing arm 1 41 forms a circle of teeth. The second arc-shaped rack 93 is fixedly arranged on one side of the hinged end of the swing arm 2 42.

The present application adjusts the transverse cutting length of the weeding device by relatively swinging the two auxiliary blade discs 5 .

[0043] As another embodiment of the present application, Figure 8 As shown, the main transmission mechanism 7 of the present application is divided into two groups, and the two groups of main transmission mechanisms 7 include two driving sprockets 71 arranged on the rotating main shaft 32, and two driven sprockets 72 connected to the rotating secondary shaft 52, and the driving sprockets 71 are respectively connected to the driven sprockets 72 through chains. The present application prevents the problem of the driving sprocket 71 and the driven sprocket 72 slipping with the chain by sprocket transmission, thereby preventing the main cutting knife 31 and the secondary cutting knife 51 from colliding with each other during the rotation process.

[0045] See also Figure 5 The auxiliary blade disc 5 of the present application is provided with a sealing plate 10 for sealing the auxiliary transmission mechanism 8. The rotation cutting radius of the main cutting knife 31 and the auxiliary cutting knife 51 is greater than the radius of the main blade disc 3 and the auxiliary blade disc 5, so that the main cutting knife 31 and the auxiliary cutting knife 51 rotate and extend out of the main blade disc 3 and the auxiliary blade disc 5 to perform cutting work. Through the above technical solution, the main cutting knife 31 and the auxiliary cutting knife 51 can contact the weeds before the main blade disc 3 and the auxiliary blade disc 5 to perform weeding.

[0046] As another embodiment of the present application, Figure 1 and Figure 5 As shown, the connection frame 2 of the present application is provided with a connection plate 21, which is detachably connected to the mobile body 1 by bolts, so as to facilitate the removal of the connection frame 2 from the mobile body 1.

[0048] See also Figure 1 The driving component 6 of the present application is a motor, and the driving motor 91 is a motor with a self-locking function. Furthermore, the swing arm 4 can be locked by arranging a self-locking mechanism on the mounting plate 61; specifically, the self-locking mechanism is a magnetic lock, and the locking rod at the output end of the magnetic lock contracts by generating suction through the power of the wire on the core rod to disconnect from the lock hole on the swing arm 4; when the wire is powered off, the core rod is demagnetized to allow the locking rod to extend under the action of the spring and plug into the lock hole on the swing arm 4 for locking.

[0049] The working principle of the present application is as follows: when in use, the driving motor 91 drives the gear 94 to drive the first arc-shaped rack 92 and the second arc-shaped rack 93 to perform synchronous relative movement, thereby driving the swing arm 1 41 and the swing arm 2 42 to perform synchronous reverse rotation to adjust the angle of the auxiliary blade disc 5 thereon, thereby adjusting the lateral weeding length of the weeding device.

[0050] The driving component 6 works to rotate the rotating main shaft 32, and the two active sprockets 71 on the rotating main shaft 32 rotate to drive the two auxiliary cutting knives 51 on both sides of the main cutting knife 31 to rotate through the chain; when the auxiliary cutting knives 51 are two in each group, the auxiliary transmission mechanism 8 is used between the two auxiliary cutting knives 51 to make the auxiliary cutting knife 1 511 and the auxiliary cutting knife 2 512 rotate synchronously to perform weeding work.
