The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Example 1

A cutter anti-tangling structure of a mini-tiller comprises a mini-tiller cutter 1 arranged on an output shaft of a gear box 4 in the mini-tiller, wherein a rotary weeding disc 2 which rotates together with the mini-tiller cutter is arranged on the mini-tiller cutter 1, a plurality of rotary blades 8 are arranged on one side, far away from the mini-tiller cutter 1, of the rotary weeding disc 2, the rotary blades 8 are perpendicular to the rotary weeding disc 2, rotary sleeves 6 and fixed discs 5 are respectively arranged at positions of the lower edges of the rotary blades 8, and the rotary sleeves 6 are positioned on the outer surface of a protective tube 7 and rotate relative to the protective tube 7; the protective tube 7 and the fixed disc 5 form a whole. The fixed disc 5 is arranged on the gear box 4, and an output shaft of the gear box 4 penetrates through the protective pipe 7 and is not in contact with the protective pipe 7.

Example 2

The utility model provides a plough quick-witted cutter anti-tangling grass structure a little, wherein rotatory weeding dish 2 be disc structure, the revolving fragment 8 that sets up on it is the T template, the revolving fragment 8 distributes around the central axis of rotatory weeding dish 2, leaves the clearance between the first lower limb 9 of revolving fragment 8 and the surface of swivel mount 6, leaves the clearance between the second lower limb 10 of revolving fragment 8 and the surface of fixed disk 5. The structure and connection relationship of the rest parts are the same as those described in any of the foregoing embodiments, and are not described herein again to avoid the tedious text.

On the basis of the above embodiments, the present invention proceeds with detailed descriptions of technical features and functions thereof, so as to help those skilled in the art fully understand the technical solution of the present invention and reproduce it.

As shown in fig. 1 to 4, in the utility model, the cutter anti-tangling structure of the mini-tiller is installed on the output shaft of the gear box 4 of the mini-tiller, specifically, the anti-tangling structure comprises a rotary weeding disk 2 and a protection disk 3, the rotary weeding disk 2 rotates along with the output shaft of the gear box 4, and the protection disk 3 is stationary relative to the output shaft of the gear box 4 or the mini-tiller cutter 1. The rotary weeding disk 2 is of a disc-shaped structure, a rotary piece 8 extending towards the direction of the gear box 4 is arranged on the rotary weeding disk, a first lower edge 9 of the rotary piece 8 is positioned above the outer surface of the rotary sleeve 6, and the rotary sleeve 6 extends into the inner side of an area formed by the rotary piece 8.

The protection dish 3 includes fixed disk 5, protective tube 7, and wherein fixed disk 5 passes through bolted connection on gear box 4, protective tube 7 welds on fixed disk 5 and constitutes integratively. The rotating sleeve 6 is located outside the protective tube 7, and the rotating sleeve 6 can rotate relative to the protective tube 7, and relative rotation can be realized through a bearing and other elements. The protective tube 7 is connected with the fixed disc 5, and the fixed disc 5 is fixed on one side of the gear box 4. Since the output shaft of the gear case 4 passes through the shielding pipe 7 without contacting the shielding pipe 7, the output shaft of the gear case 4 does not interfere with the shielding pipe 7 when rotating.

When in use, the rotary weeding disc 2 can be connected to the mini-tiller cutter 1 through bolts, so that the rotary weeding disc 2 rotates along with the mini-tiller cutter 1. As known in the above paragraphs, the protection plate 3 includes a fixing plate 5 and a protection tube 7, the fixing plate 5 is fixed on the gear box 4 of the mini-tiller through a bolt, the protection tube 7 is welded on the fixing plate 5, and an output shaft of the gear box 4 passes through the protection tube 7 and then is connected with the mini-tiller cutter 1. Because fixed disk 5 is fixed on gear box 4, so make protection disk 5 and protective tube 7 static motionless relative cutter 1, gear box 4 output shaft of ploughing machine a little is lived by protective tube 7 parcel, can play the effect of protection oil blanket. Meanwhile, the protective disc 5 and the protective pipe 7 are still relative to the cutter, so that the output shaft of the gear box 4 can be effectively prevented from being entangled by weeds.

In the above paragraph, it is known that the rotary weeding disk 2 rotates together with the mini-tiller 1, and the rotary blades 8 distributed on the rotary weeding disk 2 can cut off weeds after the rotary weeding disk 2 is entangled with weeds by the rotation. Part of the uncut weeds that may be present may enter the gap between the rotating weeding disk 2 and the protection disk 3, and the rotating blades 8 of the rotating weeding disk 2 may rub against the fixed disk 5 of the protection disk 3 to grind the entering weeds. Meanwhile, friction can be formed between the rotating piece 8 and the rotating sleeve 6, entering weeds are ground, and locking cannot occur due to relative rotation between the rotating sleeve 6 and the protective pipe 7.

Finally, although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description of the present description is for clarity reasons only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
