Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0020] Reference Figure 1-4 A fertilizer applicator for intermittent agricultural planting includes a fertilizer applicator body 1, two frames 5 are fixedly installed inside the fertilizer applicator body 1, four arc-shaped adjustment slots 6 are opened inside the frames 5, and sliding balls 7 are slidably installed inside the arc-shaped adjustment slots 6. The tops of the sliding balls 7 are fixedly connected to fixed blocks 8, and the tops of the fixed blocks 8 are rotatably connected to connecting rods 11. A screw 10 is rotatably connected inside the fertilizer applicator body 1 and located between the two frames 5. The two frames 5 are symmetrically structured with the screw 10. The outer side of the screw 10 is threadedly connected to a transmission block 14. The connecting rod 11 is away from the fixed block 8. Both ends are rotatably connected with the transmission block 14. When the fertilizer spreader body 1 needs to be used to spread fertilizer, the transmission block 14 on the outside can be driven to move laterally in the fertilizer spreader body 1 by rotating the screw 10, and then the multiple fixed blocks 8 can be driven to rotate with the help of the connecting rod 11, so that the sliding ball 7 can move in the shape of the arc-shaped adjustment groove 6 under the limiting condition of the arc-shaped adjustment groove 6, and then the spacing of the discharge port below the corrugated tube 9 can be adjusted according to the sowing spacing of different crops, so as to adapt to the production needs of different crops and improve the applicability of the equipment.

[0021] Reference Figure 3An intermittent mechanism is arranged at the top of the fertilizer spreader body 1, and the intermittent mechanism includes a preparation hopper 4 arranged at the top of the fertilizer spreader body 1, and bellows 9 are equidistantly arranged at the bottom end of the preparation hopper 4, and bulk material ports 15 are equidistantly opened at the bottom end of the inner wall of the preparation hopper 4, and the top end of the bellows 9 extends to the inside of the bulk material port 15, and the bottom end of the bellows 9 is fixedly connected to the corresponding sliding ball 7. By arranging the bellows 9 in the sliding ball 7, the number of discharge ports below the bellows 9 can be increased, thereby improving the fertilization efficiency of the equipment.

[0022] Reference Figure 3 The intermittent mechanism also includes a butterfly plate 16 arranged inside the bulk material port 15, and a rotating shaft 17 is arranged inside the preparation hopper 4. The rotating shaft 17 passes through the bulk material port 15 and is fixedly connected to the butterfly plate 16. A driving motor is fixedly installed on the rear side of the preparation hopper 4, and the output shaft of the driving motor is fixedly connected to the rotating shaft 17. When the butterfly plate 16 and the bellows 9 are in a vertical state, the butterfly plate 16 is in a closed state, and the fertilizer cannot be discharged. When fertilization is required, the rotation of the output shaft of the driving motor can drive the rotating shaft 17 to rotate, and then drive multiple butterfly plates 16 to rotate. At this time, the fertilizer can be discharged through the bulk material port 15. The intermittent control of the fertilizer can be achieved through the above operation.

[0023] Reference Figure 4 A limiting mechanism is arranged inside the fertilizer spreader body 1, and the limiting mechanism includes a limiting groove 13 provided on the side close to the two frames 5, and the limiting blocks 12 are slidably connected inside the limiting groove 13, and the two limiting blocks 12 are respectively fixedly connected to the two sides of the transmission block 14. Through the coordinated use of the limiting blocks 12 and the limiting grooves 13, an important limiting effect can be played on the transmission block 14, so as to prevent the transmission block 14 from rotating under the drive of the screw 10, and at the same time, the transmission block 14 can be made more stable during the horizontal movement.

[0024] Reference Figure 2 A servo motor 3 is fixedly installed on one side of the fertilizer spreader body 1. The output shaft of the servo motor 3 extends into the interior of the fertilizer spreader body 1 and is fixedly connected to the screw 10. The rotation of the output shaft of the servo motor 3 can drive the rotation of the screw 10.

Through the setting of the preparation hopper 4, fertilizer can be stored, and the inclined surface design can speed up the discharge speed of the fertilizer.

[0026] Working principle: First, the fertilizer is poured into the preparation hopper 4 through the feed pipe, and the servo motor 3 is started by the external control device. The screw 10 rotates to drive the transmission block 14 on its outer side to move horizontally in the fertilizer spreader body 1, and then the connecting rod 11 can be used to drive multiple fixed blocks 8 to rotate, so that the sliding ball 7 can move in the shape of the arc-shaped adjustment groove 6 under the limiting condition of the arc-shaped adjustment groove 6, and the coordinated use of the limiting block 12 and the limiting groove 13 can play an important limiting role on the transmission block 14, avoiding the transmission block 14 from rotating under the drive of the screw 10, and at the same time, the transmission block 14 can be more stable during the horizontal movement, and then the spacing of the discharge port below the corrugated tube 9 can be adjusted according to the sowing spacing of different crops, so as to meet the production needs of different crops;

[0027] When the butterfly plate 16 and the bellows 9 are in a vertical state, the butterfly plate 16 is in a closed state, and the fertilizer cannot be discharged. When fertilization is required, the rotation of the output shaft of the driving motor can drive the rotating shaft 17 to rotate, and then drive the multiple butterfly plates 16 to rotate. At this time, the fertilizer can be discharged through the bulk port 15. The above operation can achieve intermittent control of the fertilizer.
