A transmission shaft 8 is arranged between the front frame and the helical gear for transmission. The helical gear at one end of the input shaft 7 is connected to the rotary tillage equipment on the front frame through the transmission shaft 8, so that while the front frame is performing rotary tillage operations, the input shaft 7 can be driven to rotate through the transmission shaft 8, and the other end of the input shaft 7 is fixedly installed with an input gear 701 located in the L-shaped frame 1, the end of the pressure wheel shaft Ⅰ2 away from the pressing wheel 4 is fixedly installed with a positioning gear Ⅰ201 located in the L-shaped frame 1, the end of the pressure wheel shaft Ⅱ3 away from the pressing wheel 4 is fixedly installed with a positioning gear Ⅱ301 located in the L-shaped frame 1, and the other end of the intermediate shaft 5 is fixedly installed with an intermediate gear 501 located in the L-shaped frame 1.

[0034] Embodiment 2

[0035] See also Figure 4-Figure 7 On the basis of the first embodiment, the number of L-shaped frames 1 is set to two, and the two L-shaped frames 1 are arranged on both sides of the rear frame. The bevel gear on the input shaft 7 in one of the L-shaped frames 1 is connected to one end of the transmission shaft 8, and the L-shaped frame 1 is tilted on the rear frame. The transmission component in the L-shaped frame 1 is different from that in the first embodiment in that the spacing between the pressure wheel shaft Ⅰ2 and the pressure wheel shaft Ⅱ3 and the intermediate shaft 5 is adjustable, so that the height difference of the pressing wheel 4 on the pressure wheel shaft Ⅰ2 and the pressure wheel shaft Ⅱ3 can be controlled by adjusting the spacing between the pressure wheel shaft Ⅰ2 and the intermediate shaft 5, and the pressure wheel shaft Ⅱ3 and the intermediate shaft 5 respectively, in conjunction with the tilting setting of the L-shaped frame 1, that is, according to the compaction degree of the seed on the soil, the height of the furrowing disc 6 and the intermediate shaft 5 in front of the seeder and the height of the furrowing disc 6 and the intermediate shaft 5 behind the seeder can be adjusted respectively. The soil is initially compacted by utilizing the front middle rotating shaft 5 to facilitate the furrowing operation of the furrowing disc 6 and the sowing of the seeder. The height settings of the furrowing disc 6 and the middle rotating shaft 5 behind the seeder are set according to the type of seeds. For example, when the seeder sows corn seeds, a deeper sowing depth is generally required for sowing corn seeds, and during compaction, it is ensured that the soil is not over-compacted during the compaction process and sufficient compaction force is provided. When the seeder sows soybean seeds, a shallower sowing depth is generally required for sowing soybean seeds, and during compaction, it is ensured that the soil is not over-compacted to avoid affecting the respiration and growth of soybeans. After setting the height values ​​of the seeder and the furrowing disc 6 on the rear frame for sowing different seeds, the height values ​​of the two pressing wheels 4 can be further set in a targeted manner to adapt to the rotary sowing operations of different seeds.

[0036] The lateral part of the L-shaped frame 1 is provided with a slide groove Ⅰ101 located on both sides of the middle rotating shaft 5, and the pressure roller rotating shaft Ⅰ2 and the pressure roller rotating shaft Ⅱ3 respectively penetrate the two slide grooves Ⅰ101, and the pressure roller rotating shaft Ⅰ2 and the pressure roller rotating shaft Ⅱ3 are respectively provided with a sliding sleeve 102 movably sleeved with the slide groove Ⅰ101, and the sliding sleeve 102 is movably sleeved with the pressure roller rotating shaft Ⅰ2 and the pressure roller rotating shaft Ⅱ3 through a bearing, and the pressure roller rotating shaft Ⅰ2 and the pressure roller rotating shaft Ⅱ3 are both provided with a baffle 10 located on both sides of the L-shaped frame 1, through the limiting effect of the baffle 10, the sliding sleeve 102 mounted on the pressure roller rotating shaft Ⅰ2 and the pressure roller rotating shaft Ⅱ3 moves in the slide groove Ⅰ101, so as to facilitate the adjustment of the position of the pressure roller rotating shaft Ⅰ2, the positioning gear Ⅰ201, the pressure roller rotating shaft Ⅱ3 and the positioning gear Ⅱ301, and at the same time, it does not affect the rotation of the pressure roller rotating shaft Ⅰ2 driven by the positioning gear Ⅰ201 and the rotation of the pressure roller rotating shaft Ⅱ3 driven by the positioning gear Ⅱ301.

[0037] A limiting plate 11 located between the positioning gear II 301 and the baffle 10 is fixedly mounted on the pressure roller shaft II 3, and limiting gears 12 located on both sides of the positioning gear II 301 are arranged on the limiting plate 11. A guide shaft I 13 located below the input shaft 7 is movably mounted on the L-shaped frame 1 through a bearing, and the guide shaft I 13 is located on the horizontal side of the pressure roller shaft II 3. A guide gear I 14 located on the horizontal side of the limiting gear 12 is fixedly mounted on the guide shaft I 13. A slide groove II 103 located between the input shaft 7 and the guide shaft I 13 is provided at the beginning of the longitudinal portion of the L-shaped frame 1. A passive shaft 15 is movably mounted in the slide groove II 103, and a slide groove II 103 is also provided between the passive shaft 15 and the slide groove II 103. The slide groove II 103 is movably connected with the passive shaft 15 through a bearing. A passive gear 16 located above the guide gear I 14 is fixedly installed on the passive shaft 15. A guide shaft II 17 located obliquely above the guide shaft I 13 is fixedly installed on the L-shaped frame 1. The guide shaft II 17 is close to the inner angle of the L-shaped frame 1, and a guide gear II 18 is fixedly installed on the guide shaft II 17. The centers of the positioning gear I 201, the two limiting gears 12, the positioning gear II 301, the guide gear I 14 and the passive gear 16 are located on the same plane, and the positioning gear I 201, the two limiting gears 12, the positioning gear II 301, the guide gear I 14 and the passive gear 16 are connected through a chain I 19.

[0039] Through the transmission connection of chain II 22, the input gear 701 can drive the guide gear 20 and the intermediate gear 501 to rotate, and then drive the trenching disc 6 installed on the intermediate gear 501 to rotate for trenching operations. At the same time, the guide gear 20 drives the guide shaft I13 and the guide gear I14 to rotate, and then through the transmission of chain I19, drives the passive gear 16, the limiting gear 12, the positioning gear II301 and the positioning gear I201 to rotate together. The setting of the two limiting gears 12 ensures that the contact angle between the chain I19 and the positioning gear II301 is sufficient to prevent the positioning gear II301 from slipping.

[0040] When the position of the pressing wheel 4 on the pressure wheel shaft Ⅰ2 is needed, the position of the positioning gear Ⅰ201 is adjusted synchronously. For example, when the positioning gear Ⅰ201 needs to be moved to the upper left, the passive gear 16 moves downward accordingly, which can ensure that the chain Ⅰ19 between the passive gear 16 and the positioning gear Ⅰ201 remains in a tensioned state, so that the positioning gear Ⅰ201 can still rotate under the drive of the chain Ⅰ19 after adjusting the position, and then the pressing wheel 4 installed on the pressure wheel shaft Ⅰ2 rotates accordingly. When the position of the pressing wheel 4 on the pressure wheel shaft Ⅱ3 needs to be adjusted, the position of the positioning gear Ⅱ301 is adjusted synchronously, and the positioning gear Ⅰ201 and the passive gear 16 remain fixed, and it is only necessary to control the movement of the positioning gear Ⅱ301.

[0041] The inner wall of the L-shaped frame 1 is fixedly installed with a limit strip 23 located on the upper and lower sides of the slide groove Ⅰ101, and a plurality of limit holes 231 arranged at equal intervals are opened on the limit strip 23. A limit plate 24 is fixedly installed on the pressure wheel shaft Ⅰ2. The limit plate 24 and the upper and lower sides of the limit plate 11 are respectively threaded with at least one limit screw shaft 25. The limit screw shaft 25 on the limit plate 24 is engaged with the limit hole 231 on the limit strip 23, so as to fix the positioning gear Ⅰ201 and the positioning gear Ⅱ301 respectively, and then fix the pressure wheel shaft Ⅰ2 and the pressure wheel shaft Ⅱ3, so that the pressing wheel 4 after the position is adjusted is fixed.

[0042] The passive rotating shaft 15 is fixedly sleeved with blocks 26 located on both sides of the L-shaped frame 1, and the two blocks 26 limit the passive rotating shaft 15 to ensure that the passive rotating shaft 15 only moves longitudinally along the sliding sleeve 102. Bumps 261 are respectively provided on both sides of the block 26. L-shaped fixing plates 27 located on the upper and lower sides of the passive gear 16 are fixedly installed on the inner wall of the L-shaped frame 1. A threaded rod 28 is fixedly installed between the two L-shaped fixing plates 27. The two threaded rods 28 are movably sleeved with the two L-shaped fixing plates 27 on both sides of the passive gear 16 respectively. Two adjusting nuts 29 are threadedly sleeved on the threaded rod 28. The two adjusting nuts 29 are respectively arranged on the upper and lower sides of the bump 261. By setting the adjusting nuts 29 on the upper and lower sides of the bump 261, the bump 261, the block 26, the passive rotating shaft 15 and the passive gear 16 can be fixed as a whole, so that the position of the passive gear 16 can be adjusted and stably fixed.
