[0024] Reference Figures 1 to 6In this embodiment of the utility model, a blade shaft anti-tangling device for a rotary tiller for orchard soil improvement includes: a main support frame 1, a fixed blade shaft 5 disposed below the main support frame 1, multiple sets of rotary tillage blades 6 uniformly fixedly connected to the side of the fixed blade shaft 5, side protective covers 7 disposed on both sides of the fixed blade shaft 5, external threads at both ends of the fixed blade shaft 5, internal threads matching the side protective covers 7 disposed on the inner side of the side protective covers 7, the fixed blade shaft 5 and the side protective covers 7 being threadedly connected, the outer side of the side protective covers 7 being rotatably connected to the inner side of the main support frame 1, two sets of anti-tangling blade grooves 8 disposed on the side of the fixed blade shaft 5, two sets of limiting sliding grooves 9 disposed on the inner side of each set of anti-tangling blade grooves 8, a first anti-tangling cutting blade 10 and a second anti-tangling cutting blade 11 disposed inside the anti-tangling blade groove 8, multiple sets of arc-shaped cutting blades fixedly connected to the outer sides of the first anti-tangling cutting blade 10 and the second anti-tangling cutting blade 11, the first anti-tangling cutting blade 10 and the second anti-tangling cutting blade 11 being fixedly connected to the outer side of the second anti-tangling cutting blade 10 and the first anti-tangling cutting blade 11 being fixedly connected to the outer side of the second anti-tangling cutting blade 11, the first anti-tangling cutting blade 10 and the second ... The two anti-entanglement cutting blades 11 have opposite directions on their outer sides, and both the inner and outer sides of the cutting blades are sharpened. The first anti-entanglement cutting blade 10 and the second anti-entanglement cutting blade 11 are fixedly connected to the side of the limiting slide groove 9. The limiting slide strip 12 is adapted to the limiting slide groove 9. Each set of limiting slide strips 12 is slidably connected in the corresponding limiting slide groove 9. The first anti-entanglement cutting blade 10 is fixedly connected to the side of the first connecting rod 13, and the second anti-entanglement cutting blade 11 is fixedly connected to the side of the second connecting rod 14. The first connecting rod 13 is provided with a first rotating arm 15 on the side, and the first rotating arm 15 is provided with a second rotating arm 16 on the side. One end of the second rotating arm 16 is rotatably connected to a rotating disk 17. The side protective cover 7 is provided with a slot, and a drive motor 18 is locked inside. The rotating shaft of the drive motor 18 is fixedly connected to the center of one side of the rotating disk 17.

[0025] The first rotating arm 15 includes a rotating arm body 150. A central connecting shaft 151 is fixedly connected to the side of the rotating arm body 150. A first connecting shaft 152, a second connecting shaft 153, and a third connecting shaft 154 are fixedly connected to the side of the rotating arm body 150. The central connecting shaft 151 is rotatably connected to the anti-tangling tool groove 8. The first connecting shaft 152 is rotatably connected to the first connecting rod 13. The second connecting shaft 153 is rotatably connected to the second connecting rod 14. The third connecting shaft 154 is rotatably connected to the second rotating arm 16.

[0026] Using the above scheme: whenever weeds or other weeds get tangled on the fixed blade shaft 5, the first anti-tangling cutter 10 and the second anti-tangling cutter 11 will cut them off and detach themselves, preventing tangling. For weeds that are difficult to cut, they will slide along the outer arc of the first anti-tangling cutter 10 and the second anti-tangling cutter 11 to the inner edge of the two sets of cutters. At this time, the drive motor 18 will drive the rotating disk 17 to rotate. The rotating disk 17 drives the second rotating arm 16 and the first rotating arm 15 to rotate. At the same time, the first rotating arm 15 will drive the first connecting rod 13 and the second connecting rod 14 to perform alternating reciprocating motion, thereby causing the inner edges of the first anti-tangling cutter 10 and the second anti-tangling cutter 11 to move relative to each other, clamping the weeds at the inner edge of the two sets of cutters.

[0027] Reference Figure 1 A movable connecting hook 2 is rotatably connected above the main support frame 1, a drive mechanism 3 is fixedly connected above the main support frame 1, and a middle support block 4 is fixedly connected below the main support frame 1.

[0028] The above solution allows the design of the movable connecting hook 2 to easily mount the anti-tangling device for the blade shaft of the rotary tiller used for orchard soil improvement on power equipment such as tractors, enabling quick connection and disassembly, and improving the flexibility and work efficiency of the equipment.

[0029] The working principle of this utility model is: the rotary tiller is mounted on a tractor or other power equipment through the movable connecting hook 2 above the main support frame 1 to achieve quick connection;

[0030] During rotary tillage, when weeds or other weeds become entangled on the fixed blade shaft 5, the first anti-entanglement cutting blade 10 and the second anti-entanglement cutting blade 11, which are fixed to the side of the fixed blade shaft 5, will first contact and attempt to cut the weeds. Since multiple sets of arc-shaped cutting blades in opposite directions are fixed on the outside of these two sets of cutting blades, and the inner and outer sides of the cutting blades are sharpened, they can effectively cut off most of the entangled weeds, causing them to fall off on their own, thereby preventing further entanglement.

[0031] For weeds that are difficult to cut initially, most of them will slide to the inside of the first anti-tangle cutting blade 10 and the second anti-tangle cutting blade 11 as the cutting blade rotates, and come into contact with the fixed blade shaft 5. At this time, the drive motor 18 installed in the slot inside the side protective cover 7 starts to work. The rotating shaft of the drive motor 18 is fixedly connected to the center of one side of the rotating disk 17. Therefore, when the motor starts, it will drive the rotating disk 17 to rotate. The rotating disk 17 drives the second rotating arm 16 and the first rotating arm 15 to rotate. At the same time, the first rotating arm 15 will drive the first connecting rod 13 and the second connecting rod 14 to move alternately along the two sets of limiting slide grooves 9, thereby driving the inner blades of the first anti-tangle cutting blade 10 and the second anti-tangle cutting blade 11 to move relative to each other, and thus drive the inner blades of the first anti-tangle cutting blade 10 and the second anti-tangle cutting blade 11 to move closer or further apart. When the inner blades of the two sets of cutting blades come closer to each other, they will cut and clamp the weeds located between them, achieving deep anti-tangle.

[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
