[0012] The following is a detailed description of the implementation scheme of the invention in conjunction with the accompanying drawings. A circular rotating seed and fertilizer intermittent sowing and application integrated device, comprising a fertilizer box 1 with a fertilizer delivery pipe 2 and a seed box 13 with a seed delivery pipe 10, a ring body 9 is fixedly mounted on the outside of a fixed frame 12, and a long strip seed delivery hole and a long strip fertilizer delivery hole are respectively opened in the radial direction on the lower part of the ring body 9, the lower ends of the fertilizer delivery pipe 2 and the seed delivery pipe 10 are respectively connected to the long strip fertilizer delivery hole and the long strip seed delivery hole, and the outer portion of the ring body 9 is radially and axially shaped. A seed and fertilizer interval sowing drum wheel 6 is mounted on the wheel wall of the seed and fertilizer interval sowing drum wheel 6, and radial seed holes 15 and radial fertilizer holes 16 are uniformly arranged in the circumferential direction. Axial semi-axial holes 14, arc-shaped inner slide grooves 17, arc-shaped outer slide grooves 18 and column pins A3 are uniformly arranged on the opposite side end surfaces of the wheel wall of the seed and fertilizer interval sowing drum wheel 6. The arc-shaped inner slide grooves 17 and the arc-shaped outer slide grooves 18 are respectively arranged in the circumferential direction. The groove 18 is coaxially and coradially arranged at the outer side of the axial semi-axial hole 14, and the arc-shaped inner plate 19 and the arc-shaped outer plate 20 are respectively inserted into the arc-shaped inner slide groove 17 and the arc-shaped outer slide groove 18 slot holes so as to swing in the circumferential direction. A quantitative seed chamber and a quantitative fertilizer chamber are formed at the position where the radial seed hole 15 and the radial fertilizer hole 16 are located between the arc-shaped inner slide groove 17 and the arc-shaped outer slide groove 18. The seed or fertilizer sowing control body 7 is hingedly installed at the outer side of the seed hole 15 and the radial fertilization hole 16 through the insertion and cooperation of the half shaft 11 and the axial half shaft hole 14 so as to be reciprocatingly swingable. The seed or fertilizer sowing control body 7 is fixedly connected with the arc-shaped inner plate 19 and the arc-shaped outer plate 20. The driving block 8 is fixedly installed on the outer end surface of the seed or fertilizer sowing control body 7. The pin B5 is installed on the seed or fertilizer sowing control body 7, and the return tension spring 4 is hung on the pin A3 and the pin B5.

[0013] During operation, the device is installed on the fertilizer sowing machine and moves forward randomly. When each driving block 8 enters the soil in turn, under the action of soil resistance, the seed or fertilizer sowing unit 7, the half shaft 11 and the pin B5, the return tension spring 4, and the pin A3 drive the seed and fertilizer interval sowing cylinder wheel 6 to make continuous rotation around the center of the frame 12 on the annular body 9. When the seed or fertilizer sowing control body 7 in the initial static position is tightened by the return tension spring 4 and rotates to the lower side of the annular body 9, When the driving block 8 has not yet entered the soil, the arc-shaped inner piece 19 located in the arc-shaped inner chute 17 opens and connects the long strip seed delivery hole or the long strip fertilizer delivery hole on the annular body 9 with the radial seed hole 15 or the radial fertilizer hole 16 on the seed and fertilizer interval sowing cylinder wheel 6, and the seeds in the seed box 13 or the fertilizer in the fertilizer box 1 are respectively filled into the radial seed delivery hole 15 or the radial fertilizer hole 16 through the seed delivery pipe 10 or the fertilizer delivery pipe 2. At this time, the arc-shaped outer piece 20 located in the circular outer chute 18 is in the position of radially connecting the long strip seed delivery hole or the long strip fertilizer delivery hole on the annular body 9 to the radial seed delivery hole 15 or the radial fertilizer hole 16. The seeding hole 15 or the radial fertilizer hole 16 is closed at the lower end so that the filled seeds or fertilizers cannot leak out; as the seed and fertilizer interval sowing drum wheel 6 continues to rotate, the driving block 8 causes the seed or fertilizer sowing control body 7 to rotate around the semi-axis 11 on the seed and fertilizer interval sowing drum wheel 6 under the action of soil resistance, and the seed or fertilizer sowing control body 7 simultaneously drives the arc-shaped inner plate 19 and the arc-shaped outer plate 20 to rotate in the arc-shaped inner slide groove 17 and the arc-shaped outer slide groove 18 respectively, and the arc-shaped inner plate 19 rotates the annular body 9 The long strip seed delivery hole or the long strip fertilizer delivery hole on the seed and fertilizer interval sowing cylinder wheel 6 is closed and blocked to stop seed or fertilizer filling. At the same time, the arc-shaped outer piece 20 opens the lower end of the radial seed delivery hole 15 or the radial fertilizer hole 16 to sow the filled seeds or fertilizers on the land, completing the interval sowing and fertilizing continuous operation; when the driving block 8 rotates to disengage from the soil insertion contact, the seed or fertilizer sowing control body 7 returns to the initial position under the tension of the return spring 4. Cycle in sequence.
