[0027] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0028] 1. A bottom circulation telescopic flow monitoring mechanism is provided. Through the mutual cooperation between the internal components of the bottom circulation telescopic flow monitoring mechanism, the flow diversion and monitoring process during fertilization is optimized. The circulating fan cooperates with the inflatable hood to generate a continuous turbulent airflow inside the guide elbow, so that the fertilizer in the fertilization process can pass through the internal channel of the photoelectric sensor in a disorderly and fast manner, effectively preventing the fine dust in the fertilizer from adhering to the inner wall of the photoelectric sensor during the fertilization process and affecting its normal use. At the same time, the continuous circulation airflow can also be used to continuously cool the inside of the guide inclined pipe and the guide elbow to prevent the temperature of the inner wall of each pipe of the fertilization device from rising after long-term use, so that part of the fertilizer melts and re-condenses on the inner wall of the guide inclined pipe, the guide elbow, the discharge inclined pipe and the photoelectric sensor to affect the normal use of the fertilization device, ensuring that the fertilizer device can also monitor the fertilizer rate and fertilizer amount of the fertilizer in real time through the photoelectric sensor after long-term use, thereby improving the fertilization accuracy of the fertilization device;

[0029] At the same time, through the mutual cooperation among the air-guiding inclined tube, the pressure air bag and the telescopic inner rubber hose, the periodic extension and contraction of the telescopic adjustment rod drives the squeezing air bag and the telescopic inner rubber hose to deform and expand periodically, and then the fertilizer transported inside the telescopic inner rubber hose is squeezed and disturbed through the periodic change of the inner diameter of the telescopic inner rubber hose, thereby preventing the pipeline from being blocked during use of the fertilization device and improving the smoothness and stability of the use of the fertilization device.

[0030] 2. A top multi-layer separation and refinement mechanism is provided. Through the mutual cooperation between the components inside the top multi-layer separation and refinement mechanism, the process of adding fertilizers to the fertilizing device is optimized. The separation motor drives the driving mesh belt, the main crushing roller and the slave crushing roller to rotate continuously. The driving mesh belt is used to filter and screen the fertilizer inside the fertilizer box body. Fine fertilizers can directly fall to the bottom of the fertilizer box body for fertilization, while fertilizers with larger agglomerated particles can be squeezed and refined by the main crushing roller and the slave crushing roller, which effectively removes large particle components in the fertilizer, prevents uneven fertilization caused by too large fertilizer particles, and improves the fertilization effect of the fertilizer device;

[0031] At the same time, the discharging motor drives the rotating horizontal axis and the components thereon to rotate synchronously, and then the fertilizer accumulated in the lower cavity of the fertilizer box body is continuously rotated by the stirring arc sheet, and at the same time, the lifting grid is driven to be lifted and lowered periodically through the cooperation between the driving arc wheel and the driving arc lifting rod, and then the fertilizer in the lower cavity of the fertilizer box body is stirred vertically by the lifting grid, thereby preventing the phenomenon of fertilizer accumulation inside the fertilizer box body and improving the smoothness of the fertilizer adding process.

[0032] In summary, through the mutual cooperation between the components inside the bottom circulating telescopic flow monitoring mechanism and the top multi-layer separation and refinement mechanism, the fertilizer adding and spreading process is optimized, ensuring that the fertilizer can remain smooth during the adding process, effectively preventing the fertilizer from being blocked inside the fertilizer box body during the adding process, and during the fertilizer spreading process, the fertilizer spreading efficiency and spreading amount are monitored in real time to prevent the phenomenon of material breakage and uneven spreading during the fertilizer spreading process, thereby effectively improving the smoothness and safety of the use of the fertilizer device.

In the process of the continuous movement of the driving mesh belt 512, the fertilizer in the lower layer of the fertilizer box body 3 is driven to move, and the fertilizer with smaller particles can pass through the holes on the driving mesh belt 512 and fall into the lower space of the fertilizer box body 3;

[0065] After the fertilizer falls into the next cavity of the fertilizer box body 3, the discharge motor 501 is synchronously started to drive the rotating horizontal shaft 502 and the stirring arc piece 503 to rotate, and the stirring of the stirring arc piece 503 drives the fertilizer inside the lower cavity of the fertilizer box body 3 to be uniformly discharged inside the top pipe 401 for fertilization, and during the rotation of the rotating horizontal shaft 502, the driving arc wheel 504 is synchronously driven to rotate, and during the rotation of the driving arc wheel 504, the driving arc lifting rod 508 is driven to perform periodic lifting and lowering, and the lifting and lowering of the driving arc lifting rod 508 drives the lifting and lowering of the lifting grid plate 507 on the top of the limiting bottom frame 506 to perform periodic lifting and lowering along the isolation frame 505, and the fertilizer accumulated at the bottom of the fertilizer box body 3 is stirred by the lifting and lowering of the lifting grid plate 507, so as to prevent the fertilizer accumulation and blockage at the bottom of the fertilizer box body 3;

[0066] While the small-particle fertilizer passes through the driving mesh belt 512 and falls downward, the large-particle fertilizer blocks are driven to fall between the two crushing main rollers 516 by the movement of the driving mesh belt 512, and then the crushing main roller 516 is driven to rotate by the mutual cooperation between the driving pulley 519 and the driving belt 520 during the rotation of the driving long roller 510, and the two transmission gears 518 that are simultaneously engaged drive the crushing slave roller 517 to rotate synchronously relative to each other during the rotation of the crushing main roller 516, and then the agglomerated fertilizer is crushed and refined by the mutual cooperation between the crushing main roller 516 and the crushing slave roller 517, and the refined fertilizer falls into the lower cavity of the fertilizer box body 3 to participate in the subsequent fertilization process, and the end and side of the top surface of the driving mesh belt 512 are protected by the cooperation between the separation middle frame 513, the protective tail plate 514 and the isolation side plate 515 to prevent the fertilizer from falling from the side of the driving mesh belt 512 and affecting the subsequent fertilization, thereby ensuring the smooth use of the fertilization device;

[0067] During the fertilization process, the fertilizer particles are introduced into the guide bend pipe 403 through the discharge top pipe 401, and the fertilizer particles in the guide bend pipe 403 are spread into the field through the discharge inclined pipe 404. In the process of the fertilizer particles falling down along the guide bend pipe 403, the speed and amount of the fertilizer falling can be monitored in real time by the photoelectric sensor 416, thereby ensuring that the sowing device can detect uneven fertilization in time during the fertilization process;

[0068] When the fertilizer passes through the inside of the material guiding inclined tube 402, the fertilizer is flexibly guided by the telescopic inner rubber tube 412, and when the fertilizer passes through the inside of the telescopic inner rubber tube 412, the telescopic adjustment rod 406 inside the gas guiding inclined tube 405 is started to be periodically extended and retracted, and during the extension and retraction of the telescopic adjustment rod 406, the sliding extrusion block 407 is driven to slide along the inside of the gas guiding inclined tube 405, and during the sliding of the sliding extrusion block 407, the gas inside the gas guiding inclined tube 405 is introduced into the inside of the gas guiding hose 408, and the gas inside the gas guiding hose 408 passes through the sealing valve 409 and enters the inside of the extrusion airbag 410;

[0069] As the pressure of the gas inside the squeezing airbag 410 increases, the squeezing airbag 410 expands after the pressure inside the squeezing airbag 410 increases. After the squeezing airbag 410 expands, the telescopic inner rubber tube 412 is squeezed inward. The inner diameter of the telescopic inner rubber tube 412 shrinks and deforms after being squeezed. During the periodic expansion and contraction of the telescopic adjustment rod 406, the squeezing airbag 410 is driven to expand periodically, so that the shape and size of the inner cavity of the telescopic inner rubber tube 412 are periodically changed, and then the fertilizer transported inside the telescopic inner rubber tube 412 is squeezed by the expansion and contraction of the telescopic inner rubber tube 412 to prevent the telescopic inner rubber tube 412 from being blocked.

[0070] When the fertilizer passes through the interior 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 airflow is continuously sucked into the filter flat box 420 through the air intake grid 421. In the process of the external airflow passing through the interior of the filter flat box 420, the solid dust in the airflow is intercepted and collected by the collection box 422 and the filter inner fine mesh 423, and then the airflow generated by the circulation fan 419 is continuously introduced into the interior of the inflation tube 417 through the air guide pipe 418, and the circulating air is introduced into the inflation cover 413 through the inflation tube 417. Flow, and the air flow inside the inflation hood 413 is continuously introduced into the material guide elbow 403 through the air guide rectangular groove 414, thereby generating continuous turbulent airflow inside the material guide elbow 403, so that the fertilizer can be accelerated by the air flow when it falls through the internal area of ​​the photoelectric sensor 416, thereby effectively preventing the fine particles generated during the fertilization process from adhering to the inner circle of the photoelectric sensor 416, and protecting the outer side of the air guide rectangular groove 414 through the protective pipe network 415 to prevent the fertilizer inside the material guide elbow 403 from reversely entering the inflation hood 413, thereby ensuring the smooth progress of the sowing process.
