[0018] Figures 1 to 5 An automatic soil-turning device for agricultural sowing is presented, including a frame 2. A traction rod 1 is provided at the front end of the frame 2. A traveling wheel 3 and a plurality of soil turners 7 are provided on the bottom side of the frame 2. Specifically, the soil turners 7 are detachably installed on the lower end of the corresponding base column 6 through the mounting sleeve 71. The base column 6 is fixed to the bottom side of the frame 2. The soil turner 7 can be a soil-turning spiral, which can perfectly cover the seeds while turning the soil. The traveling wheel 3 is installed on the frame 2 through the traveling shaft 31. The soil turner 7 is provided with an installation plate 72 near the rear side; the frame 2 is equipped with a seed hopper 4 and a soil amendment liquid hopper 5, and the soil amendment liquid hopper 5 is provided with an injection port 51; The bottom of the seed hopper 4 and the soil amendment liquid hopper 5 are respectively provided with a number of material leakage ports 43 and liquid leakage ports 54 corresponding to the number of soil turners 7. Each material leakage port 43 and liquid leakage port 54 is respectively connected to a material leakage pipe 8 and a dripping component. The seed hopper 4 is equipped with a first rotating shaft 42 that passes horizontally through each of the discharge ports 43 and is rotatable. Each discharge port 43 on the first rotating shaft 42 is equipped with a corresponding and suitable distributor 44. The distributor 44 distributes the seeds by rotating itself, ensuring that the seeds are sown efficiently and evenly. The first rotating shaft 42 is driven to rotate by a distribution drive device 41, which can be a servo motor. The soil amendment liquid tank 5 is equipped with a second rotating shaft 53 that passes horizontally through each leakage port 54 and is rotatable. A corresponding and compatible stirring and distributing device 55 is installed on the second rotating shaft 53 within each leakage port 54. The stirring and distributing device 55 achieves stirring and distributing by its own rotation. A drive wheel 52 is provided at the end of the second rotating shaft 53. A rotating wheel is installed on the traveling rotating shaft 31. The drive wheel 52 is connected to the rotating wheel via a drive transmission, specifically through a sprocket or belt pulley. The drive wheel 52 is driven to rotate by the rotating wheel, causing the traveling wheel 3 to rotate, which in turn drives the stirring and distributing device 55 to rotate. Each sealing plate 552 extends upwards beyond its corresponding leakage port 54, and a sealing strip 553 is provided at the end of each sealing plate 552, thereby fulfilling the functions of stirring and distributing. The dripping assembly includes a leaking pipe with a liquid storage chamber 91. The liquid storage chamber 91 is set up to store liquid and achieve continuous dripping.

The soil amendment liquid tank 5 is located above the traveling wheel 3, which makes the weight distribution reasonable and further enhances the overall stability of the device.

[0021] The soil turners 7 are arranged in a staggered manner to prevent the soil turned up by the rear soil turner 7 from covering the front soil turner 7, thereby affecting the soil turning and land preparation effect.

[0022] The inner diameter of the dripping tube 9 is smaller than the inner diameter of the leaking tube. Specifically, the inner diameter of the dripping tube 9 is 3~10mm to ensure the effectiveness of dripping the soil amendment solution.
