The soil covering mechanism is installed on the frame and arranged at the rear side of the seeding mechanism for soil covering after seeding.

2. The dual mode ploughing and grass seed sowing integrated machine as claimed in claim 1, wherein, The side of the frame provided with the double-mode switching mechanism is provided with a first circular support. The inner side of the first circular support is connected with a first support disc through a bearing. The first support disc is provided with two symmetrical arc-shaped holes. The outer side of the first circular support is sleeved with an outer gear ring. The inner side of the outer gear ring is provided with a rack structure.

3. The dual mode ploughing and grass seed sowing machine as claimed in claim 2, wherein, The gear mechanism comprises a first central gear and a second central gear sleeved on the rotating shaft. The second central gear is located outside the first central gear. The side close to the second central gear of the first central gear is connected with a gear ring through a connecting plate. The connecting plate is provided with an arc-shaped groove. The first and second gear sets are symmetrically arranged on both sides of the central gear.

4. The dual mode plowing and grass seed sowing integrated machine according to claim 3, characterized in that, The first gear set comprises a first gear, a second gear and a third gear installed on a second sliding shaft. The first gear is matched with the outer gear ring. The second gear is matched with the first central gear and drives the gear ring to rotate. The third gear is matched with the second central gear. The second gear set comprises a fourth gear and a fifth gear installed on a first sliding shaft. The fourth gear is matched with the gear ring. The fifth gear is matched with the second central gear. The first sliding shaft is used to realize the combination and dispersion of the first rotary tillage blade and the third rotary tillage blade. The second sliding shaft is used to realize the combination and dispersion of the second rotary tillage blade and the third rotary tillage blade.

5. The dual mode ploughing and grass seed sowing machine as claimed in claim 4, wherein, The end of the rotating shaft is rotatably connected with one end of a rotating frame. The end of the rotating frame is provided with a through hole. The other end of the rotating frame is fixedly connected with the outer gear ring. The outer gear ring is rotated through the rotating frame.

6. The dual mode ploughing and grass seed sowing machine as claimed in claim 5 wherein, The movable rotary tillage blade handle is uniformly provided with three groups of clamping grooves. The rotating shaft shaft is provided with a rotating space and a long shaft. One end of the rotating space is communicated with the outside through a through hole. The end of the long shaft is provided with a spline groove. The long shaft is rotated by extending the hand wheel into the rotating space and matching with the spline groove. Three groups of locking through holes are arranged on the circumference of the rotating shaft. One end of the spring is connected with the locking through hole through a step. The other end of the spring is matched with a pressing plate. The pressing plate is clamped with the clamping groove by extending the clamping block out of the locking through hole. The pressing plate is also hinged with the long shaft through a connecting rod. The long shaft is rotated to realize the retraction and extension of the pressing plate.

7. The dual mode ploughing and grass seed sowing machine as claimed in claim 1 wherein, The frame between the seeding mechanism and the rotary tillage mechanism is also provided with a soil crushing wheel.

8. The dual mode ploughing and grass seed sowing machine as claimed in claim 1, wherein, The seeding mechanism comprises a seed groove matched with a seed tube below, and a seed plate is arranged inside the seed groove and above the seed tube.

9. The dual mode ploughing and grass seed sowing machine as claimed in claim 1, wherein, The covering mechanism comprises walking wheels installed on both sides of the frame, and a spiral shaft is further arranged between the two groups of walking wheels.

10. The dual mode plowing and grass seed planting machine of claim 9, wherein, A plurality of covering plates are arranged on the spiral shaft.
