[0089] A first transmission shaft 35, one end of which is connected to the engine, and the other end of which is connected to a first universal joint 36, the first universal joint 36 is connected to a second universal joint 38 via a first cross shaft 37, one end of the second universal joint 38 is connected to a second transmission shaft 39, one end of the second transmission shaft 39 is connected to a third universal joint 40, the third universal joint 40 is connected to a fourth universal joint 42 via a second cross shaft 41, one end of the fourth universal joint 42 is connected to a third transmission shaft 43, an end of the third transmission shaft 43 is sleeved with a first bevel gear 45, one side of the first bevel gear 45 is meshed with a second bevel gear 46, and the middle of the second bevel gear 46 is connected to a fourth transmission shaft 48;

[0090] The first bevel gear 45 and the second bevel gear 46 are installed in the protective shell 20 through the first bearing 44 and the second bearing 47 respectively.

[0091] Specifically, the first universal joint 36, the first cross shaft 37, the second universal joint 38, the second cross shaft 41, the third universal joint 40, the second cross shaft 41 and the fourth universal joint 42 constitute a cross-shaft universal coupling, through which the first transmission shaft 35, the second transmission shaft 39 and the third transmission shaft 43 are connected. The cross-shaft universal coupling can make the second transmission shaft 39 and the third transmission shaft 43, which are not on the same axis or have a large axis angle or a large axial movement, rotate continuously at the same angular speed and reliably Transmit torque and motion; the first bearing 44 is installed at the front opening of the protective shell 20, and the second bearing 47 is installed at the left opening of the protective shell 20. By arranging the first bearing 44 and the second bearing 47, when the third transmission shaft 43 and the fourth transmission shaft 48 rotate, the protective shell 20 has no influence on them. The protective shell 20 confines the first bevel gear 45, the second bevel gear 46, the first bearing 44 and the second bearing 47 in a closed space to protect the four from being affected by impurities such as dust, thereby ensuring the performance of the gear transmission;

[0092] The power of the engine is transmitted to the second transmission shaft 39 and the third transmission shaft 43 through the first transmission shaft 35 , thereby driving the first bevel gear 45 to rotate. The first bevel gear 45 transmits the power to the fourth transmission shaft 48 by meshing with the second bevel gear 46 , thereby realizing the rotation of the fourth transmission shaft 48 .

[0094] The first gear 49 , the second gear 50 and the third gear 51 are installed on the side of the housing 24 , and the rotating shaft runs across the two side portions of the housing 24 .

[0095] Specifically, one end of the rotating shaft is installed on one side of the shell 24 through the third gear 51, and the other end of the rotating shaft is sleeved with a third bearing 54. The outer ring of the third bearing 54 is fixed with a first flange 53, and the first flange 53 is fixed to the shell 24 through flange bolts. In this way, the other end of the rotating shaft is installed on the other side of the shell 24; the bidirectional spiral knife 52 is bounded by the middle of the rotating shaft, and the spiral blades on both sides are symmetrically arranged and both are outwardly rotating, which is used to turn the soil outward during rotary tillage.

[0096] When the fourth transmission shaft 48 rotates, it drives the first gear 49 to rotate synchronously. The first gear 49 transmits power to the second gear 50 by meshing with the second gear 50. The second gear 50 transmits power to the third gear 51 by meshing with the third gear 51, so that the third gear 51 drives the rotating shaft to rotate synchronously, thereby driving the spiral cutter 52 to perform rotary tillage.

[0097] In addition, it should be noted that the support frame 65 of the fertilizing device 31 is fixed to the shell 24 of the rotary tillage and ridging device 19 , and the shell 24 provides support for the fertilizing device 31 .

After the bolt 32 is installed in the round hole, the connecting plate is locked or loosened by the second nut 33.

[0105] When adjusting the width, all the second nuts 33 on the connecting plate can be loosened. At this time, the bolts 32 and the second nuts 33 pass through the round holes and remain stationary, and the connecting plate is driven to move back and forth along the horizontal straight slots 76 to drive the side plates to move, thereby realizing the width adjustment of the movable baffle 26, and then tightening the second nut 33 to fix it; when adjusting the height, the first nut 30 located on the lower end surface of the second support plate 25 and the second nut 33 on the back plate are loosened, and the second nut 33 on the connecting plate remains stationary. By rotating the first nut 30 on the upper end surface of the second support plate 25, the screw rod 29 moves up and down by thread transmission, thereby driving the upper scraper 27 to rise and fall. At this time, the movable baffle 26, the bolts 32 and the second nuts 33 on the hanging plate 34 move up and down along the vertical straight slots 77 opened on the hanging plate 34, and then tightening the second nut 33 on the hanging plate 34 and the first nut 30 on the lower end surface of the second support plate 25 to fix them.
