[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is scientific and reasonable, and it is safe and convenient to use:

[0028] 1. A bottom circulation telescopic flow monitoring mechanism is provided. Through the mutual cooperation of the components inside the bottom circulation telescopic flow monitoring mechanism, the diversion and monitoring processes during fertilization are optimized. Through the circulation fan cooperating with the air inflation cover to generate continuous turbulent airflow inside the material guiding elbow, the fertilizer during fertilization can pass through the internal channel of the photoelectric sensor disorderly and quickly, effectively preventing the fine dust in the fertilizer from adhering to the inner wall of the photoelectric sensor during fertilization and affecting its normal use. At the same time, through the continuous blowing of the circulating airflow, the inside of the material guiding inclined pipe and the material guiding elbow can be continuously cooled to prevent the temperature of the inner walls of each pipeline from rising after the fertilization device is used for a long time, causing some fertilizers to melt and recondense on the inner walls of the material guiding inclined pipe, the material guiding elbow, the discharge inclined pipe, and the photoelectric sensor, affecting the normal use of the fertilization device, ensuring that the fertilization rate and fertilization amount of the fertilizer can be monitored in real time by the photoelectric sensor even after the fertilizer device is used for a long time, and improving the fertilization accuracy of the fertilization device;

[0029] Meanwhile, through the mutual cooperation among the air guide inclined pipe, the pressure airbag and the telescopic inner rubber pipe, the periodic expansion and contraction of the extrusion airbag and the telescopic inner rubber pipe are driven by the periodic expansion and contraction of the telescopic adjusting rod. Furthermore, the fertilizer transported inside is extruded and disturbed by the periodic change of the inner diameter of the telescopic inner rubber pipe, preventing the phenomenon of blockage inside the pipeline during the use of the fertilizing device and improving the smoothness and stability of the fertilizing device.

[0030] 2. A top multi-layer separation and refinement mechanism is provided. Through the mutual cooperation among the components inside the top multi-layer separation and refinement mechanism, the process of adding fertilizer to the fertilizing device is optimized. The separation motor drives the driving mesh belt, the main crushing roller and the auxiliary crushing roller to rotate continuously. The fertilizer inside the fertilizer tank main body is filtered and screened by the driving mesh belt. Fine fertilizers can directly fall to the bottom of the fertilizer tank main body for fertilization, while large agglomerated fertilizers can be extruded and refined by the main crushing roller and the auxiliary crushing roller, effectively removing the large particle components in the fertilizer and preventing the phenomenon of uneven fertilization caused by too large fertilizer particles, improving the fertilization effect of the fertilizer device.

[0031] Meanwhile, the discharge motor drives the rotating cross shaft and the components thereon to rotate synchronously. Then, the stirring arc-shaped piece continuously rotates the fertilizer accumulated in the lower cavity of the fertilizer tank main body. At the same time, through the mutual cooperation between the driving arc-shaped wheel and the driving arc-shaped lifting rod, the lifting grid plate is driven to lift periodically. Furthermore, the fertilizer in the lower cavity of the fertilizer tank main body is stirred vertically by the lifting grid plate, preventing the phenomenon of fertilizer accumulation inside the fertilizer tank main body and improving the smoothness of the fertilizer adding process.

[0032] In summary, through the mutual cooperation among the components inside the bottom circulating telescopic flow monitoring mechanism and the top multi-layer separation and refinement mechanism, the processes of adding and spreading fertilizer are optimized, ensuring the smoothness of fertilizer addition, effectively preventing blockage inside the fertilizer tank main body during fertilizer addition, and real-time monitoring the spreading efficiency and spreading amount of fertilizer during fertilizer spreading to prevent the phenomena of material interruption and uneven spreading during fertilizer spreading, thereby effectively improving the smoothness and safety of the fertilizer device.

[0063] The working principle and usage process of the present invention: During the use of the fertilizer seeding device of the present invention, the connecting bracket 1 needs to be connected to the tail of the corresponding driving device first, and the bottom of the connecting bracket 1 is supported by the supporting bottom wheels 2. Then, the fertilizer is poured into the main body 3 of the fertilizer box for temporary storage, so as to evenly introduce the fertilizer into the discharge top pipe 401 through the main body 3 of the fertilizer box for fertilization through the discharge top pipe 401;

[0064] During the process of adding fertilizer into the interior of the fertilizer tank body 3, it is necessary to refine the large granular fertilizer that needs to be coagulated. The support grid plate 521 can assist in supporting the fertilizer particles piled up on the upper layer of the fertilizer tank body 3 to reduce the pressure of the fertilizer on the bottom components of the support grid plate 521. Then, synchronously start the separation motor 509 to drive the driving long roller 510 to rotate continuously. During the rotation of the driving long roller 510, cooperate with the limit guide roller 511 to drive the driving mesh belt 512 to move continuously. During the continuous movement of the driving mesh belt 512, drive the fertilizer in the lower layer of the fertilizer tank body 3 to move, and enable the fertilizer with smaller particles to pass through the holes on the driving mesh belt 512 and fall into the lower space of the fertilizer tank body 3;

[0065] After the fertilizer falls into the lower cavity of the fertilizer tank body 3, synchronously start the discharging motor 501 to drive the rotating horizontal shaft 502 and the stirring arc plate 503 to rotate. Through the stirring of the stirring arc plate 503, drive the fertilizer in the lower cavity of the fertilizer tank body 3 to be evenly discharged into the fertilizer application pipe 401 for fertilization. And during the rotation of the rotating horizontal shaft 502, synchronously drive the driving arc wheel 504 to rotate. During the rotation of the driving arc wheel 504, drive the driving arc lifting rod 508 to perform periodic lifting and lowering. Through the lifting and lowering of the driving arc lifting rod 508, drive the lifting grid plate 507 on the top of the limit bottom frame 506 to perform periodic lifting and lowering along the inside of the isolation frame 505. Through the lifting and lowering of the lifting grid plate 507, stir the fertilizer piled up at the bottom of the fertilizer tank body 3 to prevent the fertilizer at the bottom of the fertilizer tank body 3 from piling up and blocking;

[0066] While the small granular fertilizer passes through the driving mesh belt 512 and falls downward, the movement of the driving mesh belt 512 drives the large granular fertilizer block to fall between the two main crushing rollers 516. Then, during the rotation of the driving long roller 510, through the mutual cooperation between the driving belt pulley 519 and the driving belt 520, drive the main crushing roller 516 to rotate. During the rotation of the main crushing roller 516, the two meshing transmission gears 518 drive the secondary crushing roller 517 to perform synchronous relative rotation. Furthermore, through the mutual cooperation between the main crushing roller 516 and the secondary crushing roller 517, crush and refine the caked fertilizer, and make the refined fertilizer fall into the lower cavity of the fertilizer tank body 3 to participate in the subsequent fertilization process. And through the cooperation between the separation middle frame 513, the protective tail plate 514 and the isolation side plate 515, protect the end and side of the top surface of the driving mesh belt 512 to prevent the fertilizer from falling from the side of the driving mesh belt 512 and affecting the subsequent fertilization, ensuring the smooth use of the fertilization device;

[0067] During the fertilization process, fertilizer particles are introduced into the inside of the material guiding elbow 403 through the discharging top pipe 401, and the fertilizer particles inside the material guiding elbow 403 are spread onto the field via the discharging inclined pipe 404. During the process of the fertilizer particles falling downward along the material guiding elbow 403, the photoelectric sensor 416 can monitor the falling speed and quantity of the fertilizer in real time, thereby ensuring that when uneven fertilization occurs during the fertilization process of the sowing device, it can be detected in a timely manner;

[0068] During the process of the fertilizer passing through the inside of the discharging inclined pipe 402, the fertilizer is flexibly guided by the telescopic inner rubber tube 412, and while the fertilizer passes through the inside of the telescopic inner rubber tube 412, the telescopic adjusting rod 406 inside the air guiding inclined pipe 405 is started to perform periodic telescoping. During the telescoping process of the telescopic adjusting rod 406, the sliding extrusion block 407 is driven to slide along the inside of the air guiding inclined pipe 405. During the sliding process of the sliding extrusion block 407, the gas inside the air guiding inclined pipe 405 is introduced into the inside of the air guiding hose 408, and the gas inside the air guiding hose 408 passes through the sealing valve 409 and enters the inside of the extrusion airbag 410;

[0069] As the pressure inside the extrusion airbag 410 continuously rises with the increase of the gas inside, after the pressure inside the extrusion airbag 410 rises, it expands. After the extrusion airbag 410 expands, it squeezes the telescopic inner rubber tube 412 inward. After the telescopic inner rubber tube 412 is squeezed, its inner diameter shrinks and deforms. During the periodic telescoping process of the telescopic adjusting rod 406, the extrusion airbag 410 is driven to perform periodic expansion, so that the shape and size of the inner cavity of the telescopic inner rubber tube 412 change periodically. Furthermore, the fertilizer conveyed inside it is squeezed through the telescoping of the telescopic inner rubber tube 412 to prevent blockage inside the telescopic inner rubber tube 412;

[0070] And while the fertilizer passes through the inside of the photoelectric sensor 416, the circulation fan 419 is started to generate a continuous negative pressure inside the filter flat box 420, and the external air flow is continuously sucked into the filter flat box 420 through the air intake grille 421. During the process of the external air flow passing through the inside of the filter flat box 420, the solid dust in the air flow is intercepted and collected by the collection box 422 and the inner fine filter net 423. Then, the air flow generated by the circulation fan 419 is continuously introduced into the inside of the inflation small tube 417 through the main air guide pipe 418, and the circulating air flow is introduced into the inside of the inflation hood 413 through the inflation small tube 417. The air flow inside the inflation hood 413 is continuously introduced into the inside of the material guiding elbow 403 through the air guide rectangular groove 414, and thus a continuous turbulent air flow is generated inside the material guiding elbow 403, so that when the fertilizer drops through the inner area of the photoelectric sensor 416, it can be accelerated by the air flow, and thus effectively avoids the attachment of fine particles generated during the fertilization process to the inner ring of the photoelectric sensor 416. The outer side of the air guide rectangular groove 414 is protected by the protective pipe network 415 to prevent the fertilizer inside the material guiding elbow 403 from flowing back into the inside of the inflation hood 413, ensuring the smooth progress of the spreading process.
