In this embodiment, in order to ensure the stability of the connection between the walking assembly 13 and the side beam 12, the walking assembly 13 includes a pseudo-beam 137, the pseudo-beam 137 is connected to the side beam 12 through a reinforcing rib, the steering driving mechanism 133 is mounted on the pseudo-beam 137, and the pseudo-beam 137 is rotatably connected to the wheel carrier 132 through a pivoting support 138. In this connection, the steering driving mechanism 133 is coaxial with the steering shaft of the traveling wheels 131, so that the driving force is small, and the service life of the steering driving mechanism 133 is prolonged.

Referring to fig. 2, since the planting row spacing of crops is different, in order to improve the adaptability of the device, the side beam 12 is connected with the beam frame 11 through a telescopic beam 121, the telescopic beam 121 is inserted into the beam frame 11, and the telescopic beam 121 is locked with the beam frame 11 through a clamping piece 14. When the row spacing of the crops is small, if the length of the telescopic beam 121 inserted into the beam frame 11 is large, the distance between the side beam 12 and the beam frame 11 is small, and thus the wheel spacing between the two rows of travelling wheels 131 in the same row on both sides of the beam frame 11 is small. When the row spacing of crops is larger, the telescopic beam 121 is more drawn out from the beam frame 11, so that the wheel spacing between the two travelling wheels 131 on the same row at both sides of the beam frame 11 is larger to match the row spacing of the crops. Referring to fig. 8, in order to ensure the stability of the telescopic beam 121 in the beam frame 11, a plurality of positioning holes 111 are provided on the beam frame 11, the clip 14 includes a U-shaped clip 141, the clip 141 is clipped on the beam frame 11, and a locking screw 142 provided corresponding to the positioning holes 111 passes through the clip 141 and the beam frame 11 to abut against the telescopic beam 121.

Referring to fig. 9, since the cross member 25 is connected to the weeding assembly 30, the weight thereof is large, and in order to provide a sufficient driving force to the moving plate 23, the traverse assembly 20 further includes a traverse motor 26 and a pull rod 27 in this embodiment. The traverse motor 26 is installed on the cross beam 25, one end of each of two equal-length pull rods 27 is connected and rotatably connected with one end of each of active rods 28, the other ends of the pull rods 27 are respectively connected with two ends of the fixing plate 22, and the other ends of the active rods 28 are connected with a driving shaft of the traverse motor 26. Since the position of the fixed plate 22 is fixed and the connecting position of the two pull rods 27 corresponds to the middle of the fixed plate 22, when the traversing motor 26 is started, the end of the active rod 28 connected with the traversing motor 26 rotates, and the other end of the active rod 28 cannot move, so that the end of the active rod 28 connected with the traversing motor 26 moves, and the traversing motor 26 and the cross beam 25 generate displacement. The traverse push rod 24 and the traverse motor 26 are driven by the traverse beam 25, so that the traverse can be smoothly generated. Even if the active lever 28 slightly changes the distance between the cross beam 25 and the fixed plate 22 during the rotation, the active lever 28 does not fail to operate due to interference due to the amount of expansion and contraction of the pull rod 27 itself, the assembly distance between the moving plate 23 and the fixed plate 22, and the like.

Referring to fig. 5, in order to adjust the angle of the weeding blade 31 inserted into the soil, a first connecting rod 33 is hinged between the weeding motor 32 and the cross beam 25, an angle adjusting screw 34 is connected between the weeding motor 32 and the cross beam 25, one end of the angle adjusting screw 34 is connected with the weeding motor 32, and the other end is in threaded connection with a nut on the cross beam 25. The angle adjusting screw 34 is disposed above the first link 33, the angle adjusting screw 34, the weeding motor 32, the first link 33 and the cross beam 25 form a quadrilateral structure, when the angle adjusting screw 34 is screwed, the length of one side of the quadrilateral changes, the shape of the quadrilateral changes, and thus the angle of the weeding knife 31 connected to one side of the quadrilateral changes.

Further, referring to fig. 10, since the ridge is not flat, in order to maintain the depth of the weeding knife 31, and avoid damaging the root of the crop when the ridge is too deep, or prevent the weeding assembly 30 from completely removing the weeds when the ridge is too shallow, the weeding assembly 30 further includes a depth-limiting wheel 35. The relative height of the weeding knife 31 and the depth wheel 35 is fixed, and the depth wheel 35 fluctuates along with the soil surface, so that the adjustment of the soil penetration depth of the weeding knife 31 is realized. Specifically, the depth wheel 35 and the weeding motor 32 are both connected with a connecting plate 36, the connecting plate 36 is hinged with a plurality of second connecting rods 37 to form a parallelogram profiling structure, one corner of the profiling structure, which is close to the cross beam 25, is hinged with the cross beam 25, and the cross beam 25 limits the rotation angle of the second connecting rods 37. Because the parallelogram profile modeling structure is unstable structure, when the soil height changes, depth wheel 35 rises along the soil surface, then connecting plate 36 moves up, and the parallelogram profile modeling structure can take place the deformation, carries out the profile modeling motion to the soil surface. When the depth wheel 35 moves downwards, the weeding assembly 30 is in a head-lowering state, and one corner of the parallelogram profiling structure extending below the cross beam 25 abuts against the lower surface of the cross beam 25, so that the weeding assembly 30 is prevented from being excessively lowered; when the depth wheel 35 moves upwards, the weeding assembly 30 is in a head-up state, and the second connecting rod 37 in the vertical direction of the parallelogram copying structure abuts against the side edge of the cross beam 25, so that the weeding assembly 30 is prevented from being excessively lifted up.

Further, in order to improve the weeding effect, the weeding assembly 30 further comprises an S-shaped spring tooth 38, and the S-shaped spring tooth 38 is installed behind the weeding blade 31. The weeding cutter 31 tilts the soil, and the S-shaped elastic teeth 38 generate pulse vibration during working, so that the tilted soil blocks are crushed, and the surface soil achieves the effect of fine tillage and fine cropping. Furthermore, the height of the weeding assembly 30 relative to the walking wheel 131 is different due to different terrains, in order to adjust the overall height of the weeding assembly 30, guide grooves 15 which are oppositely arranged along the vertical direction are fixed on two sides in the beam frame 11, and two ends of the lifting beam 21 are inserted into the guide grooves 15 and are fixed with the guide grooves 15 through clamping pieces 14. Therefore, the height of the lifting beam 21 can be adjusted, the weeding assembly 30 connected with the lifting beam 21 is driven to adjust the height, and the application range of the device is further widened.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Various other modifications and alterations will occur to those skilled in the art upon reading the foregoing description. This need not be, nor should it be exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
