[0039] An anti-caking mechanism. The anti-caking mechanism includes two hollow rods 8 rotatably connected to the side wall of the spiral conveyor blade 7. A plurality of dispersing rods 9 are fixedly connected to the side walls of the two hollow rods 8. A rectangular groove 10 is formed in the inner wall of the conveying groove 2. A rectangular frame 11 is slidably connected to the inner wall of the rectangular groove 10. The side wall of the rectangular frame 11 is elastically connected to the inner wall of the rectangular groove 10 through a plurality of first springs 12. An annular groove 13 is formed in the side wall of the rectangular frame 11 away from the first spring 12. A rotatable circular ring 14 is hermetically slidably connected to the inner wall of the annular groove 13. The side wall of the rotating pipe 6 is fixedly connected to the side wall of the circular ring 14 through a plurality of L-shaped rods 15 (as Figure 5 shown).

[0040] The side walls of the two hollow rods 8 penetrate the side wall of the circular ring 14 and extend into the annular groove 13 (as Figure 7 shown), and the side walls of the two hollow rods 8 are hermetically and rotatably connected to the side wall of the circular ring 14. A toothed ring 16 is fixedly connected to the inner wall of the annular groove 13. The side walls of the two hollow rods 8 located in the annular groove 13 are fixedly connected to a first gear 17. The side walls of the two first gears 17 mesh with the side wall of the toothed ring 16.

[0041] The rotation of the rotating pipe 6 drives the spiral conveyor blade 7 to rotate, drives the two hollow rods 8 to rotate. At this time, the rotation of the rotating pipe 6 also drives the circular ring 14 to rotate through a plurality of L-shaped rods 15. Then the two hollow rods 8 and the circular ring 14 rotate synchronously. At this time, the two first gears 17 rotate self-rotation under the action of the toothed ring 16, thereby driving the two hollow rods 8 to rotate self-rotation, driving the plurality of dispersing rods 9 to rotate, so that the plurality of dispersing rods 9 can disperse the liquid fertilizer raw materials at different positions in the conveying groove 2, avoiding caking and affecting subsequent operations.

[0042] A plurality of first rods 18 are fixedly connected to the side wall of the housing 1 close to the rectangular groove 10. A vertical plate 19 is slidably connected to the side walls of the plurality of first rods 18. A second rod 20 is fixedly connected to the side wall of the vertical plate 19 close to the side wall of the housing 1. A third rod 21 is fixedly connected to the side wall of the rectangular frame 11 close to the first spring 12. The side wall of the third rod 21 penetrates through the side wall of the housing 1. The second rod 20 and the third rod 21 are facing each other (as Figure 5 shown).

[0043] One end of the hollow shaft 4 away from the circular plate 3 is fixedly connected with a reciprocating threaded pipe 22. The side wall of the reciprocating threaded pipe 22 is threadedly connected with the side wall of the vertical plate 19.

[0044] The rotation of the hollow shaft 4 drives the rotation of the reciprocating threaded pipe 22. Under the action of the plurality of first rods 18, the vertical plate 19 is driven to intermittently move towards or away from the housing 1, driving the second rod 20 to intermittently move towards or away from the third rod 21. When the second rod 20 moves and abuts against the third rod 21, the rectangular frame 11 will be driven to move in the rectangular groove 10 at this time. Then, through the ring 14 and the plurality of L-shaped rods 15, the rotating pipe 6 is driven to move on the side wall of the hollow shaft 4, driving the spiral conveying blade 7 to move. When the second rod 20 moves and separates from the third rod 21, at this time, the rectangular frame 11 returns to its original position under the action of the plurality of first springs 12. Then, through the ring 14 and the plurality of L-shaped rods 15 again, the rotating pipe 6 is driven to move on the side wall of the hollow shaft 4, driving the spiral conveying blade 7 to move again, so that the spiral conveying blade 7 can horizontally move during rotation, scraping the liquid fertilizer raw materials on the inner side wall of the conveying groove 2, avoiding the residue of the liquid fertilizer raw materials, and at the same time increasing the dispersion area of the dispersion rod 9 for the liquid fertilizer raw materials, improving the anti-caking effect on the liquid fertilizer raw materials.

[0045] A high-pressure hot air pipe 26 is fixedly communicated with the inner wall of the annular groove 13. Two sleeves 27 corresponding to the two hollow rods 8 are rotatably connected to the side wall of the circular plate 3 (as Figure 8 shown). The side wall of the hollow rod 8 penetrates through the inner wall of the corresponding sleeve 27. A plurality of second clamping rods 28 are fixedly connected to the side wall of the hollow rod 8 located in the sleeve 27. The side walls of the plurality of second clamping rods 28 are all slidably connected to the side wall of the sleeve 27. Two L-shaped plates 29 corresponding to the two hollow rods 8 are slidably connected to the side wall of the circular plate 3. Rotating joints 30 are fixedly connected to the side walls of the two L-shaped plates 29 away from the circular plate 3. One end of the hollow rod 8 away from the first gear 17 is fixedly communicated with one side of the rotating joint 30. The other side of the rotating joint 30 is fixedly communicated with an air outlet pipe 31.

[0046] Two sleeves 27 and a plurality of second clamping rods 28 are provided, so that the two hollow rods 8 can move horizontally during rotation. At this time, the two L-shaped plates 29 are driven to move horizontally on the side wall of the housing 1, which will not affect the connection between the rotary joint 30 and the hollow rod 8. At the same time, two rotary joints 30 are provided, so that the two hollow rods 8 stably transport the hot air inside them during rotation.

[0047] During the rotation of the two hollow rods 8, at this time, hot air is pumped into the annular groove 13 through the high-pressure hot air pipe 26. Subsequently, the hot air will enter the two hollow rods 8 for heat conduction, transfer the heat of the hot air to the liquid fertilizer raw material, heat and evaporate the water in the liquid fertilizer raw material, avoid caking due to excessive water inside the liquid fertilizer raw material, and the hot air will flow out through the hollow rod 8 and the rotary joint 30 into the air outlet pipe 31.

[0048] A plurality of corresponding through grooves 32 are formed in the side walls of the hollow shaft 4 and the rotating pipe 6 (as Figure 3 shown). Filter plates 33 are fixedly connected to the inner walls of the plurality of through grooves 32 located on the hollow shaft 4. Transverse plates 34 corresponding to the plurality of filter plates 33 are fixedly connected to the inner wall of the hollow shaft 4. Arch-shaped plates 36 are elastically connected to the side walls of the plurality of transverse plates 34 close to the filter plates 33 through a plurality of second springs 35. Plug rods 37 are fixedly connected to the side walls of the arch-shaped plates 36 far from the second springs 35. The plurality of plug rods 37 correspond to the filter holes on the filter plates 33 one by one.

[0049] The convex surface of the arch-shaped plate 36 is close to the side wall of the transverse plate 34. T-shaped pipes 38 are fixedly communicated with the inner walls of the two air outlet pipes 31. The side wall of the T-shaped pipe 38 far from the air outlet pipe 31 is fixedly communicated with the inner wall of the hollow shaft 4.

[0050] First solenoid valves 39 are installed on the inner walls of the two air outlet pipes 31, and second solenoid valves 40 are installed on the inner walls of the T-shaped pipes 38.

[0051] When transporting the powdery liquid fertilizer raw material, at this time, the two first solenoid valves 39 are electrified and opened, and the second solenoid valves 40 are de-energized and closed. Then, the high-pressure hot air in the two hollow rods 8 will directly flow out through the two air outlet pipes 31. At this time, the high-pressure hot air will not enter the hollow shaft 4 through the T-shaped pipe 38. At this time, the arch-shaped plate 36 is in the initial position under the action of the plurality of second springs 35, that is, the plurality of plug rods 37 are inserted into the filter holes on the filter plates 33 to prevent the powdery liquid fertilizer raw material from entering the hollow shaft 4;

[0052] When transporting large granular liquid fertilizer raw materials and it is necessary to clean the dust on the liquid fertilizer raw materials, at this time, the two first solenoid valves 39 are powered off and closed and powered on and opened, and the second solenoid valve 40 is powered on and opened. Then, the high-pressure hot air located in the two hollow rods 8 will enter the hollow shaft 4 through the T-shaped pipe 38. When the high-pressure hot air flows at the arched plate 36, according to Bernoulli's principle, at this time, the pressure on the convex surface of the arched plate 36 is less than the pressure on its horizontal surface. Then, the arched plate 36 moves towards the direction close to the cross plate 34, so that the plurality of blocking rods 37 are removed from the filter holes on the filter plate 33. When the high-pressure hot air flows in the hollow shaft 4, according to Bernoulli's principle, at this time, the pressure in the hollow shaft 4 is relatively low. Then, the dust impurities on the large granular liquid fertilizer raw materials in the conveying groove 2 can be absorbed into the hollow shaft 4 through the plurality of through grooves 32 and the plurality of filter plates 33 and discharged, which improves the processing efficiency of this type of liquid fertilizer raw materials in the subsequent process.

[0053] When transporting the liquid fertilizer raw materials, the liquid fertilizer raw materials are added into the conveying groove 2 through the feed pipe 41. Subsequently, the driving motor 23 rotates, drives the hollow shaft 4 to rotate through the second gear 24 and the third gear 25, drives the rotating pipe 6 to rotate through the plurality of first clamping rods 5, and drives the spiral conveying blade 7 to rotate, so as to perform spiral conveying on the liquid fertilizer raw materials located in the conveying groove 2, so that the liquid fertilizer raw materials flow out through the discharge pipe 42.

[0054] When the rotating pipe 6 rotates to drive the spiral conveying blade 7 to rotate, it drives the two hollow rods 8 to rotate. At this time, the rotation of the rotating pipe 6 also drives the ring 14 to rotate through the plurality of L-shaped rods 15. Then, the two hollow rods 8 and the ring 14 rotate synchronously. At this time, the two first gears 17 rotate selflessly under the action of the toothed ring 16. Then, it drives the two hollow rods 8 to rotate selflessly, drives the plurality of dispersing rods 9 to rotate, so that the plurality of dispersing rods 9 can disperse the liquid fertilizer raw materials at different positions in the conveying groove 2, avoiding their caking and affecting the subsequent operations.

[0055] And the rotation of the hollow shaft 4 drives the reciprocating threaded pipe 22 to rotate. Under the action of the plurality of first rods 18, it drives the vertical plate 19 to intermittently move towards or away from the housing 1, drives the second rod 20 to intermittently move towards or away from the third rod 21. When the second rod 20 moves and abuts against the third rod 21, at this time, it will drive the rectangular frame 11 to move in the rectangular groove 10. Then, it drives the rotating pipe 6 to move on the side wall of the hollow shaft 4 through the ring 14 and the plurality of L-shaped rods 15, drives the spiral conveying blade 7 to move. When the second rod 20 moves and separates from the third rod 21, at this time, the rectangular frame 11 returns to its original position under the action of the plurality of first springs 12. Then, it drives the rotating pipe 6 to move on the side wall of the hollow shaft 4 again through the ring 14 and the plurality of L-shaped rods 15, and drives the spiral conveying blade 7 to move again, so that the spiral conveying blade 7 can move horizontally during the rotation process, scrape the liquid fertilizer raw materials on the inner side wall of the conveying groove 2, avoid the residue of the liquid fertilizer raw materials, and at the same time increase the dispersion area of the dispersing rods 9 for the liquid fertilizer raw materials, improving the anti-caking effect on the liquid fertilizer raw materials.

[0056] Meanwhile, during the rotation of the two hollow rods 8, hot air is pumped into the annular groove 13 through the high-pressure hot air pipe 26 at this time. Subsequently, the hot air will enter the two hollow rods 8 for heat conduction, transfer the heat of the hot air to the liquid fertilizer raw material, and heat and evaporate the water in the liquid fertilizer raw material, avoiding caking inside the liquid fertilizer raw material due to excessive water;

[0057] Two first solenoid valves 39 and one second solenoid valve 40 are provided. When transporting the powdery liquid fertilizer raw material, the two first solenoid valves 39 are energized and opened at this time, and the second solenoid valve 40 is de-energized and closed. Then, the high-pressure hot air in the two hollow rods 8 will directly flow out through the two air outlet pipes 31. At this time, the high-pressure hot air will not enter the hollow shaft 4 through the T-shaped pipe 38. At this time, the arched plate 36 is in the initial position under the action of a plurality of second springs 35, that is, a plurality of blocking rods 37 are inserted into the filter holes on the filter plate 33 to prevent the powdery liquid fertilizer raw material from entering the hollow shaft 4;

[0058] When transporting large granular liquid fertilizer raw materials and it is necessary to clean the dust on the liquid fertilizer raw materials, the two first solenoid valves 39 are de-energized and closed and then energized and opened at this time, and the second solenoid valve 40 is energized and opened. Then, the high-pressure hot air in the two hollow rods 8 will enter the hollow shaft 4 through the T-shaped pipe 38. When the high-pressure hot air flows at the arched plate 36, according to Bernoulli's principle, the pressure on the convex surface of the arched plate 36 is less than the pressure on its horizontal surface at this time. Then, the arched plate 36 moves towards the direction close to the cross plate 34, so that a plurality of blocking rods 37 are removed from the filter holes on the filter plate 33. When the high-pressure hot air flows in the hollow shaft 4, according to Bernoulli's principle, the pressure inside the hollow shaft 4 is relatively low at this time. Then, the dust and impurities on the large granular liquid fertilizer raw materials in the conveying groove 2 can be absorbed into the hollow shaft 4 through a plurality of through grooves 32 and a plurality of filter plates 33 and discharged, improving the processing efficiency of this type of liquid fertilizer raw material in the follow-up.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
