As shown in fig. 3, the weeding blade 7 is mounted on the in-wheel motor 9 through a weeding blade head 8. The outside cover of in-wheel motor 9 is equipped with annular staple bolt. The periphery of annular staple bolt is provided with a plurality of weeding knife rest 8, every weeding knife rest 8 is last to install a weeding blade 7. The weeding blades are transversely arranged, and the plane of the weeding blades is parallel to the central axis of the hub motor 9. The knife rest and the weeding blade are fixed in a hoop mode, so that the design is suitable for different line widths and soil properties, and the blades with different lengths, widths and shapes can be quickly replaced, so that the optimal weeding effect is achieved.
As shown in fig. 1, the grass winding prevention assembly includes two shields 10 symmetrically disposed at left and right sides of a middle portion of the hub motor. As can be seen in fig. 1, the protective cover 10 is located between the second support and the third support. The grass winding preventing blades 11 are arranged on the outer wall of the protective cover 10, one end of the protective cover 10 is connected with the side wall of the hub motor 9, a circular through hole is formed in the other end of the protective cover, a plurality of twisting rotary blades 6 are arranged on the periphery of the through hole, a twisting fixed blade 4 is arranged above the same end of the second supporting portion and the same end of the third supporting portion respectively, and the twisting fixed blade 4 is mounted on the second supporting portion or the third supporting portion through a blade mounting frame 5. The diameter of one end of the protective cover 10, which is close to the hub motor 9, is larger than that of one end of the protective cover 10, which is far away from the hub motor 9, namely, one end of the protective cover is large, the other end of the protective cover is small, and the two ends are connected through an arc surface. The protection casing 10 cover is established in the outside of the mid portion of in-wheel motor 9, plays the guard action to in-wheel motor 9, can avoid weeds winding on in-wheel motor 9, avoids in-wheel motor 9 to damage because of weeds winding.
As shown in fig. 4, the shield 10 is spindle-shaped. The spindle-shaped boot 10 has a larger diameter at an end closer to the in-wheel motor than at an end farther from the in-wheel motor. The protection casing 10 is last to have seted up a plurality of via holes, and a plurality of via holes make protection casing 10 form the fretwork design, and the earth that the protection casing 10 was inside was taken to the rotatory area of in-wheel motor 9 that fretwork made leaks. The protective cover adopts a spindle shape, and the design ensures that part of weeds are sent to a twisting cutter (the twisting cutter comprises a twisting fixed blade 4 and a twisting rotary blade 6) according to the expectations, and the twisting cutter is used for twisting off the weeds, so that the weeding process is ensured to be smoothly carried out. The fusiform protective cover design can also increase the intensity of protective cover, helps stress dispersion, increase of service life.
The protective cover 10 is fixed on the hub motor 9 in a welding mode, and the hub motor 9 rotates to drive the protective cover 10 to rotate. During rotation of the protective cover 10, the spindle-shaped design of the protective cover 10 drives weeds wound on the protective cover 10 to move towards the narrow end of the protective cover 10, and most weeds wound on the protective cover 10 can be cut off by the grass-winding preventing blades 11 on the protective cover 10 during movement. The rest small part of weeds can be brought to the tail end of the protective cover 10, the twisting fixed blade 4 and the twisting rotary blade 6 are mutually matched, and the part of weeds are removed through the mutual twisting of the twisting fixed blade 4 and the twisting rotary blade 6, so that the purpose of preventing grass from being entangled is achieved.
The grass winding preventing blade 11 is fixed on the protective cover 10 in a welding mode, and the grass winding preventing blade 11 is obliquely arranged on the surface of the protective cover 10 and has a certain included angle with the central axis of the protective cover 10. Through with prevent twining grass blade 11 slope and place on the surface of protection casing 10, improved the stability to the weeds cutting process, ensured that most weeds are cut off smoothly at this stage, in addition, prevent twining grass blade 11 slope and place can also reduce the side direction pressure, break up the tangential force of blade into horizontal and vertical force, be favorable to reducing the wearing and tearing of blade.
As shown in fig. 2, the twisted fixed blade 4 is fixed to the twisted fixed blade mount 5 by bolts, and the twisted fixed blade mount 5 is fixed to the support frame 12. As shown in fig. 4, the twisted rotary blades 6 are uniformly welded to the end of the shield 10 by welding. In the rotation process of the hub motor 9, the twisting rotary blade 6 and the twisting fixed blade 4 are mutually matched to realize twisting, so that weeds are cut off, and the purpose of preventing grass from being entangled is achieved.
According to the utility model, two spindle-shaped protective covers 10 (with large diameter near the motor end and small distal end) are arranged on two sides of the hub motor 9, and the weeds wound on the protective covers 10 are guided to move towards the tail ends of the protective covers 10 by utilizing centrifugal force according to the design of weed winding and movement rules. The protective cover is provided with a plurality of through holes for reducing weight and preventing soil from accumulating. By arranging a plurality of inclined grass winding preventing blades on the outer wall of the protective cover and rotating along with the protective cover 10, the cutting edges of the grass winding preventing blades 11 are similar to fly cutters to cut and wind weeds, so that most grass winding problems are solved. Through having welded transposition rotary blade 6 at the terminal circular through-hole periphery of protection casing 10, set up transposition fixed blade 4 in the relevant position department on support frame 12 simultaneously, the blade precision fit (clearance 1~2 millimeters) of transposition fixed blade 4 and transposition rotary blade 6, reach here through the transposition action even root cutting when residual weeds, thoroughly stop secondary and twine the grass hidden danger. In addition, a cleaning blade 13 is arranged below the first support part, and when the mechanism works to lift soil and sundries, the cleaning blade is cooperated with the weeding blade to change the track of the sundries, remove the sundries, maintain the cleaning of the working surface and protect the internal structure of the equipment.
The working principle of the utility model is as follows:
When the weeding mechanism disclosed by the utility model is operated, the weeding blade 7 is driven to rotate among Chinese herbal medicine rows by virtue of the hub motor, so that the weeding mechanism can remove weeds. When small weeds are encountered, the blades crush them directly. However, when facing long and tough weeds such as goosegrass, the weeds may become entangled with the rotating weeding blades 7 onto the spindle-shaped hollow-out cover 10. At this time, the grass-entanglement preventing blade provided on the cover acts to twist off most of the weeds. While the remaining small portion of the weed is sent to the end of the shroud as the shroud continues to rotate. In this position, the twisting rotary blade 6 and the twisting fixed blade 4 cooperate with each other to thoroughly twist off the part of the remaining weeds by the twisting action. In addition, when the mechanism is used for weeding rapidly, partial soil or residues can be carried up, and at the moment, the cleaning blades 3 on the fixing frame can play a role in removing the impurities, so that the weeding operation is efficient and clean.
The above examples are only illustrative of the preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model, and various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model should fall within the scope of protection defined by the claims of the present utility model without departing from the spirit of the present utility model.
