[0029] The anti-soil backfilling unit includes connecting block 1 (901), connecting bar 2 (902), soil covering plate (903), sliding groove (904), slider (1001), connecting block 2 (1002), connecting bar 3 (1003), support rod (1004), connecting block 3 (1005), connecting bar 4 (1006) and electric push rod (11). Connecting block 1 (901) is fixedly connected to the outer side of movable plate 1 (403). There are two connecting blocks 1 (901), which are respectively fixedly connected to both ends of the outer sides of movable plate 1 (403) and movable plate 2 (404). And connecting bar 2 (902) is rotatably connected to the mutually approaching surfaces of the two connecting blocks 1 (901), providing a stable connection and adjustment mechanism for the soil covering plate (903), allowing the soil covering plate (903) to be adjusted in angle as required. The upper part of the soil covering plate (903) is rotatably connected to the connecting block 1 (901) through the connecting bar 2 (902). The sliding groove (904) is opened on the outer side of the soil covering plate (903). The slider (1001) is slidably connected to the sliding groove (904). The output end of the electric push rod (11) is fixedly connected to the bottom of the slider (1001). By sliding the slider (1001) in the sliding groove (904), the angle of the soil covering plate (903) is adjusted to adapt to different sowing requirements. The bottoms of the two connecting blocks 2 (1002) are fixedly connected to both ends of the upper surface of the slider (1001). One end of the support rod (1004) is rotatably connected to the mutually approaching surfaces of the two connecting blocks 2 (1002) through the connecting bar 3 (1003). The support rod (1004) maintains the stability of the soil covering plate (903) and prevents deformation or displacement when covering the soil. One surface of the two connecting blocks 3 (1005) is fixedly connected to the inner side of the soil covering plate (903). The other end of the support rod (1004) is rotatably connected to the mutually approaching surfaces of the two connecting blocks 3 (1005) through the connecting bar 4 (1006). The height of the soil covering plate (903) is less than the height of the movable plate. After sowing, it covers the soil, prevents soil backfilling, protects the seeds and promotes germination. There are two groups of anti-soil backfilling units, which are respectively arranged on the outer sides of movable plate 1 (403) and the movable plate.

[0030] Working principle: According to the sowing requirements, the depth and width of the furrow opening are preset in advance. Start cylinder 1 (3), and drive the furrow opener (4) to descend to the soil surface through its telescopic movement. According to the set furrow opening width, start cylinder 2 (801) and cylinder 3 (802). Through the telescopic movements of cylinder 2 (801) and cylinder 3 (802), push the movable plate 1 (403) and the movable plate 2 (404) to rotate along the connecting bar 1 (407), thereby changing the distance between the movable plates and realizing the adjustment of the furrow opening width. At the same time, the auxiliary wheel (5) rolls in the soil, reducing the frictional resistance and making the furrow opening smoother.

[0031] Push the agricultural machinery forward to make the furrow opener 4 create a groove with the required width in the soil. At the same time, the sowing device scatters seeds into the groove. After sowing is completed, start the electric push rod 11. The electric push rod 11 adjusts the angle of the soil covering plate 903 through the sliding of the slider 1001 in the sliding groove 904. The support rod 1004 ensures the stability of the soil covering plate 903 when adjusting the angle. The soil covering plate 903 covers the soil after sowing to prevent soil backfilling and ensure the germination rate of seeds. By continuing to move the agricultural machinery forward, the soil covering plate 903 covers the soil on the seeds to complete the sowing process. After sowing is completed, turn off all cylinders and the electric push rod 11, and lift the furrow opener 4 above the ground.
