[0030] Example 1

[0031] See also Figure 1-5As shown, an anti-winding soil micro-tillage machine includes a transmission rod 1, a transmission box 2, a mounting shaft 3 and a rotary tillage blade 6. The transmission rod 1, the transmission box 2 and the mounting shaft 3 form a transmission mechanism for cooperating with a motor to drive the rotary tillage blade 6 to rotate;

[0032] The upper end of the transmission rod 1 is connected to the output shaft of the driving motor, and the mounting shaft 3 is fixed to the output ends on both sides of the transmission box 2 by bolts;

[0033] The mounting plate 7 is fixedly sleeved on the surface of the mounting shaft 3, and the rotary tillage blade 6 is fixedly mounted on the mounting plate 7 by bolts;

[0034] A grass guard plate 4 is provided on the mounting plate 7, and a chute 10 is provided in the grass guard plate 4. A knife plate 9 is slidably connected to the chute 10 through a reciprocating mechanism. A grass-cutting blade 11 is provided on the surface of the knife plate 9. A plurality of knife grooves 5 are provided on the surface of the grass guard plate 4. The number of grass-cutting blades 11 corresponds to the number of knife grooves 5, and each knife groove 5 has an oblique angle on its surface. A plurality of rotary tillage blades 6 are provided, and are arranged in groups of two, and each two rotary tillage blades 6 are symmetrically designed;

[0035] When working, first, the mounting shaft 3 is fixed on the output ends on both sides of the transmission box 2 by bolts, and the driving motor is turned on. The transmission rod 1 is driven by the motor, and the transmission rod 1 drives the gear mechanism inside the transmission box 2 to drive the mounting shaft 3 to rotate. At the same time, the mounting shaft 3 drives the rotary tillage blade 6 on its surface to plow the soil. When the mounting shaft 3 rotates, it also drives the grass guard plate 4 to rotate. When the grass guard plate 4 rotates, weeds, grass roots and other impurities will be stuck in the knife groove 5 on the surface of the grass guard plate 4, and then the reciprocating mechanism drives the knife plate 9 to move back and forth, and the grass cutting blade 11 on the surface of the knife plate 9 cuts the weeds, thereby achieving the anti-entanglement effect. The weeds and rhizomes are cut off by the grass cutting blade 11, thereby reducing the resistance of the rotary tillage blade 6, improving the rotary tillage efficiency of the soil, and also making the operation of the staff more labor-saving. The knife groove 5 can improve the weed cutting efficiency of the rotary tillage blade 6.

[0036] The reciprocating mechanism includes a fixed ring 8, which is fixedly mounted on the surface of the transmission case 2. A ring groove 16 is provided on the surface of the fixed ring 8. A sliding shaft 13 is fixedly connected to the surface of the blade 9. The end of the sliding shaft 13 away from the blade 9 passes through the sliding groove 10 for sliding connection, and the end is fixedly connected to a slide plate 12. The slide plate 12 is installed in the ring groove 16 for sliding connection. A guide block 14 and a guide block 2 15 are fixedly connected to the side wall of the ring groove 16. The surfaces of the guide block 14 and the guide block 2 15 are both chamfered, and the guide block 14 and the guide block 2 15 are symmetrically designed. At least two guide blocks 14 and the guide block 2 15 are provided. The grass cutting blade 11 is detachable and fixedly installed by bolts. A cutting edge is provided on both sides of the grass cutting blade 11, and is arc-shaped.

[0037] During operation, the grass guard 4 will drive the sliding shaft 13 to move, and the sliding shaft 13 will drive the slider to slide in the annular groove 16. The slider will first contact the guide block 2 15, and through the bevel angle of the surface of the guide block 2 15, it will drive the slider to move in the direction close to the blade 9. At the same time, the slider will drive the sliding shaft 13 to slide, and the sliding shaft 13 will drive the blade 9 to slide in the slide groove 10. After the slider passes through the guide block 2 15, it will contact the guide block 14. The guide block 14 is symmetrically designed. When the slider contacts the guide block 14, the bevel angle of the surface of the guide block 14 will force the slider to Move away from the knife plate 9, through the guide block 14 and the guide block 2 15, in cooperation with the rotating mounting shaft 3, the grass cutting blade 11 can be driven to achieve the effect of moving back and forth, and the weeds and rhizomes wrapped around the surface of the mounting shaft 3 are cut off, thereby ensuring the rotary tillage efficiency of the rotary tiller. At the same time, the grass cutting blade 11 is detachable and can be replaced after the blade is damaged, thereby greatly improving the practicality of the mechanism. The blades designed on both sides can cut on both sides at the same time when the grass cutting blade 11 moves back and forth, thereby greatly improving the grass cutting efficiency.

[0038] A push plate 17 is slidably connected to the slide groove 10 through an elastic member, and the push plate 17 fits with the blade 9. The slide groove 10 is designed to be open on one side. A threaded shaft 21 is connected to the grass guard plate 4 through a thread. A groove 20 is provided on the grass guard plate 4. A connecting block 22 is slidably connected to the groove 20. The end of the threaded shaft 21 is rotatably connected in the connecting block 22. A positioning block 19 is slidably connected to the surface of the connecting block 22 through a spring. A top block 18 is fixedly connected to the surface of the positioning block 19. A mounting groove is provided on the surface of the blade 9 relative to the top block 18.

[0039] During operation, the spring-driven push plate 17 can always press the blade 9 toward the transmission box 2, so that the grass-breaking blade 11 is always in the slide groove 10 when not in use, avoiding damage. At the same time, it can protect the staff and avoid the grass-breaking blade 11 scratching the staff. When the grass-breaking blade 11 needs to be replaced, the threaded shaft 21 is twisted to move the threaded shaft 21 outward, and the connecting block 22 is driven to slide into the groove 20. At the same time, the connecting block 22 drives the top block 18 out of the mounting groove, releasing the positioning of the blade 9. At this time, the blade 9 can be pulled out from the position of the single-side opening of the slide groove 10, making it easy to replace the grass-breaking blade 11.

[0040] Example 2

[0041] See also Figure 6 As shown, in comparison with Example 1, as another embodiment of the present invention, a protective plate 23 is rotatably connected in the annular groove 16, and the sliding shaft 13 passes through the protective plate 23 for sliding connection; when working, the protective plate 23 rotatably connected to the surface of the annular groove 16 can protect the annular groove 16 to prevent mud from entering the annular groove 16, raising the slider, and thus affecting the sliding of the blade 9.

[0042] Example 3

[0043] See also Figure 7 As shown, compared with Example 1, as another implementation of the present invention, the slider can be changed to a guide shaft 25, and the guide block 14 and the guide block 2 15 are connected end to end to form a continuous guide groove 24, so that the grass cutting blade 11 can slide back and forth more linearly, and at the same time can reduce the wear caused by the collision between the guide block 14, the guide block 2 15 and the slide plate 12.
