In this embodiment, the seed metering hopper 620 and the seed metering pipe 630 are provided in multiple numbers and one-to-one correspondence, so as to simultaneously transport seeds, speed up the work efficiency and improve the seeding speed. The middle part of the seed metering pipe 630 is fixed to the side of the third frame 130 close to the seeding box 610, which plays a reinforcing role to avoid the seed metering pipe 630 being bent by external forces such as soil during the seeding operation. In some embodiments, the seeding box 610 can also be provided with a replenishment port for replenishing seeds.

[0055] Further, the sowing assembly 600 further comprises a power transmission group 640, a seed delivery shaft 650 and a seed delivery wheel 660.

The seed delivery wheel 660 is sleeved on the seed delivery shaft 650 and passes through the inside of the seed delivery hopper 620. The power transmission group 640 is driven to rotate the seed delivery shaft 650 and further drive the seed delivery wheel 660 to avoid seed stacking. In the embodiment, the power transmission group 640 is a gear group with a driving device. In the embodiment, the driving device can be a motor. In other embodiments, it can also be an electric motor. In addition, the outer circumferential surface of the seed delivery wheel 660 is arranged with grooves recessed towards the central axis of the seed delivery wheel 660. The seed delivery wheel 660 is arranged with a plurality of seed delivery wheels corresponding to the seed delivery hopper 620 and perpendicular to the feeding port of the seed delivery tube 630. The seed delivery wheel 660 plays a guiding role in seed delivery to avoid seed stacking in the feeding port of the seed delivery hopper 620 and multiple seeds entering the same sowing groove, which leads to excessive sowing density and mutual inhibition of the growth of multiple seeds. Further, the seed delivery shaft 650 is arranged with a sowing knob at the end away from the power transmission group 640 to control the sowing amount.

[0056] In the embodiment, referring to Figures 4-6 , the pressing groove ring 320, the discharge port 6301 and the seed covering harrow blade 530 are located on the same straight line along the advancing direction of the soil reverse rotation controlled wide and deep belt sowing machine to correspond the sowing groove of the soil to the seed dropping position and the covering position.

[0057] In the embodiment, referring to Figures 1-4 and Figure 13The first frame 110 has first slots 1101 on both sides of its top surface for the second frame 120 to be inserted. The third frame 130 has a second slot 1301 on its top surface near the first frame 110 for the second frame 120 to be inserted. The side of the second frame 120 near the third frame 130 and the side of the third frame 130 away from the second frame 120 are connected by an adjusting screw 800. The first slots 1101, the second slots 1301, and the adjusting screw 800 work together to allow the second frame 120 and the third frame 130 to follow the terrain relative to the first frame 110, adapting to terrain undulations and ensuring that the seeder can operate stably on different terrains. Knobs are provided at the first slots 1101 and the second slots 1301 to adjust their width. Meanwhile, since the connection between the adjusting screw 800 and the third frame 130 is close to the side of the self-rotating compaction roller 400, the adjusting screw 800 also plays the role of adjusting the height of the self-rotating compaction roller 400 according to different terrains, so that the self-rotating compaction roller 400 also has the function of imitating terrain, can adapt to different terrains, and ensure that the degree of compaction and leveling of the soil tends to be consistent.

[0058] In this embodiment, a soil retaining plate is provided on the side of the first frame 110 away from the second frame 120 and on the periphery of the rotary tillage component 200 to prevent soil from splashing when the rotary tillage component 200 turns the soil.

[0059] In this embodiment, the clay soil anti-rotation depth-controlling wide-width seeder further includes a three-point suspension mechanism, which is connected to the first frame 110 for connection with a tractor. The tractor provides traction to propel the clay soil anti-rotation depth-controlling wide-width seeder forward. Simultaneously, the tractor's power unit transmits power to the first drive assembly 140 via a universal joint drive shaft. The first drive assembly 140 and the second drive assembly 150 are connected via the universal joint drive shaft, thus the tractor's power unit drives both the first drive assembly 140 and the second drive assembly 150. In this embodiment, the first drive assembly 140 and the second drive assembly 150 are gear transmission sets. In some embodiments, other transmission devices may also be used.
