The right side of the adjusting blocks 50 extends into the feed trough 32. The left side of the feed column 31 passes through the left side wall of the feed box 26 and is fixedly connected to an adjusting screw 51. An adjusting knob 52 is threaded onto the adjusting screw 51. The right side of the adjusting knob 52 is rotatably connected to the left side of the connecting plate 49. Seeding troughs 53 are provided on the upper end of the right side wall of the adjusting block 50 and the inner right side wall of the feed trough 32. During sowing, the seeds are poured into the storage cylinder 25 and rotated. The distance between the two sowing troughs 53 can be adjusted by adjusting the knob 52, so that the device can adapt to the sowing of different types of seeds. When fertilizing, the fertilizing and sowing mechanism 7 can be lowered by pushing out the electric push rod 21. At this time, the lower end of the outlet pipe 29 is inserted into the ground as the device moves. When the auxiliary wheel 33 contacts the ground, it rolls. Then, through the cooperation of the active toothed disc 36 and the driven toothed disc 35, the rotating rod 34 and the guide column 31 are driven to rotate. The fertilizer in the storage cylinder 25 is introduced into the conveying pipe 28 by the guide trough 32, and then discharged through the outlet pipe 29.

[0038] A conveying pipe 28 is provided below the mounting plate 27. The upper end of the conveying pipe 28 passes through the mounting plate 27 and the lower side wall of the guide box 26 and is connected to the guide box 26.

[0039] The spraying mechanism 8 includes an adjusting vertical rod 37, a pesticide storage cylinder 42, and a spraying pump 41. The pesticide storage cylinder 42 is located above the frame 1. The adjusting vertical rod 37 is fixed to the upper end of the frame 1. A vertical adjusting pipe 38 is slidably connected to the adjusting vertical rod 37. Spraying rods 39 are hinged to both ends of the vertical adjusting pipe 38. Several pesticide nozzles 40 are provided on the spraying rods 39. The input end of the spraying pump 41 penetrates the upper side wall of the pesticide storage cylinder 42 and communicates with the pesticide storage cylinder 42. The input end of the spraying pump 41 extends to the bottom of the pesticide storage cylinder 42. The output end is fixedly connected to a drug delivery pipe 43, and several drug nozzles 40 are all connected to the drug delivery pipe 43. Each of the several drug nozzles 40 is equipped with an independent switch. When spraying, the independent switches on each drug nozzle 40 are turned on and off according to the spraying needs. Then, the drug in the storage cylinder 42 is introduced into the drug nozzle 40 through the drug delivery pipe 43 by the spray pump 41 to carry out drug spraying. When the two spray poles 39 are unfolded, the spraying end of the drug nozzle 40 points to the ground, which can achieve a larger area of ​​spraying operation.

[0040] In environments with narrow spacing between crops, the spraying rods 39 on both sides are flipped upwards and fixed to the outside of the vertical adjustment tube 38 using ropes. At this time, the spraying rods 39 are set vertically, and the pesticide nozzles 40 on the left and right sides can be used to spray pesticides to the left and right sides respectively, ensuring that the device can work smoothly in environments with narrow spacing between crops. At the same time, setting the spraying rods 39 vertically reduces the overall width of the equipment and avoids affecting the normal operation of the equipment after unfolding.

[0041] A locking bolt 344 is provided on the outside of the vertical adjustment tube 38. The locking bolt 344 passes through the side wall of the vertical adjustment tube 38 and abuts against the side wall of the adjustment rod 37. The locking bolt 344 is threadedly connected to the side wall of the vertical adjustment tube 38. A limit rope 45 is fixedly connected to the spraying rod 39. The end of the limit rope 45 away from the spraying rod 39 is fixedly connected to the outer wall of the vertical adjustment tube 38. During the spraying operation, the height of the spraying rod 39 can be adjusted by adjusting the position of the vertical adjustment tube 38. Specifically, when using it, loosen the locking bolt 344, hold the vertical adjustment tube 38 and move it up and down. When the spraying rod 39 is moved to the appropriate height, stop and tighten the locking bolt 344.

[0042] The support frame 20 is located in front of the auxiliary frame 14. Two auxiliary plates 16 are fixedly connected to the front end of the auxiliary frame 14. Two through holes 17 are opened on the auxiliary plates 16. A single connecting pipe 19 is fixedly connected to the rear end of the support frame 20. A connecting pin 18 is provided on the outside of the auxiliary plate 16. The end of the connecting pin 18 near the frame 1 passes through the through hole 17 and the single connecting pipe 19 in sequence and is connected to a retaining ring. A second connecting frame 23 is fixedly connected to the rear end of the support frame 20. A lifting electric push rod 21 and a spring buckle 24 are provided on the rear side of the support frame 20. The lower end of the lifting electric push rod 21 is hinged to the upper end of the auxiliary frame 14. A first connecting frame 22 is fixedly connected to the output end of the lifting electric push rod 21. Both the first connecting frame 22 and the second connecting frame 23 are sleeved on the spring buckle 24. The spring buckle 24 is set to provide space for the fertilization and sowing mechanism 7 to fluctuate, so that the fertilization and sowing mechanism 7 can adapt to moving on uneven ground.

[0043] The tail of the second separator 47 is connected to a double connecting pipe 48. When spraying is required but fertilization is not needed, pull out the connecting pin 18 to separate the auxiliary plate 16 and the single connecting pipe 19, and open the spring buckle 24 to separate the lifting electric push rod 21 and the support frame 20, thus completing the disassembly of the fertilization and sowing mechanism 7. Then, place the double connecting pipe 48 between the two auxiliary plates 16, and use the two pins to connect the auxiliary plates 16 and the double connecting pipe 48. At this time, the installation of the first separator 46 is completed. It works with the second separator 47 to ensure that the left and right sides are separated during the spraying process, reducing the interference of crop stems and leaves on the equipment and ensuring the stability of the spraying operation.

[0044] Working principle: During use, add the fertilizer to be applied into the storage cylinder 25, and simultaneously add the pesticide to be sprayed into the pesticide storage cylinder 42. Before fertilizing and spraying, adjust the height of the fertilization and sowing mechanism 7 and the spraying rod 39. During adjustment, manually lift one side of the adjusting crossbar 10 and loosen the corresponding locking bolt 12. The spacing adjusting tube 11 slides on the adjusting crossbar 10. After the two connecting rods 13 are adjusted to the appropriate position, tighten the locking bolt 12. At this time, the two fertilization and sowing mechanisms 7... After the spacing adjustment is completed, the fertilizer sowing mechanism 7 can be lowered by pushing out the lifting electric push rod 21. At this time, the lower end of the outlet pipe 29 is inserted into the ground as the device moves. When the auxiliary wheel 33 contacts the ground, it rolls, which in turn drives the rotating rod 34 and the guide column 31 to rotate through the cooperation of the active gear plate 36 and the driven gear plate 35. The fertilizer in the storage cylinder 25 is guided into the conveying pipe 28 through the guide groove 32, and then discharged through the outlet pipe 29. At the same time, the position of the adjusting block 50 is adjusted by the cooperation of the adjusting knob 52 and the adjusting screw 51, thereby changing the size of the space exposed by the guide groove 32 and thus adjusting the amount of fertilizer. During sowing, the distance between the two sowing troughs 53 is adjusted by rotating the adjusting knob 52, so that the device can adapt to the sowing of different types of seeds. When it is necessary to adjust the fertilization depth, the locking bolt 20 is loosened, and the position of the outlet pipe 29 is adjusted in the up and down direction to adjust the fertilization depth. When fertilization is not required, the lower end of the outlet pipe 29 is inserted into the ground by pushing out the lifting electric push rod 21. When the fertilization mechanism is raised, fertilization is paused once the auxiliary wheel 33 is no longer in contact with the ground. When adjusting the height of the spraying rod 39, loosen the locking bolt 344 and move the vertical adjustment tube 38 in the up and down direction. After the height of the spraying rod 39 is adjusted, pause and tighten the locking bolt 344. When spraying, select to turn on and off the independent switches on each drug nozzle 40 according to the spraying needs. Then, use the spraying pump 41 to introduce the drug in the storage cylinder 42 into the drug nozzle 40 through the delivery pipe 43 to carry out drug spraying. When spraying is required but fertilization is not, pull out the connecting pin 18 to separate the auxiliary plate 16 and the single connecting pipe 19, and open the spring buckle 24 to separate the lifting electric push rod 21 and the support frame 20, thus completing the disassembly of the fertilization and sowing mechanism 7; then place the double connecting pipe 48 between the two auxiliary plates 16, and use the two pins to connect the auxiliary plate 16 and the double connecting pipe 48. At this time, the installation of the first separator 46 is completed. It works with the second separator 47 to ensure that the left and right sides are separated during the spraying process, reducing the interference of crop stems and leaves on the equipment and ensuring the stability of the spraying operation.
