Under the condition of a certain air volume, the smaller the air inlet, the greater the wind speed, and the faster the fertilizer moves in the fertilizer delivery pipe 6. The larger the air inlet, the lower the wind speed, and the slower the fertilizer moves in the fertilizer delivery pipe 6. The size of the air inlet is controlled by the wind control lever 15 to achieve wind control, and then control the speed of fertilizer falling. The rotation speed of the fertilizer wheel 42 is controlled by the fertilizer discharge motor, and then the amount of fertilizer entering the fertilizer delivery pipe 6 is controlled. The fertilizer in the fertilizer storage box 17 enters the fertilizer discharge space of the fertilizer discharger and falls onto the fertilizer discharge wheel 42.

The seeds in the seed storage box 22 fall into the seed meter body 39 and fall into the seeding groove 41 of the seeding wheel 40. The seeding motor 25 drives the seeding wheel 40 to rotate, so that the seeds in the seeding groove 41 fall into the venturi tube 10. The seeding fan 21 provides power for the seeds in the venturi tube 10. Under the action of the seeding fan 21, the seeds enter the distribution head 23 and enter the corresponding seed delivery tube 8 from each outlet of the distribution head 23. Under the action of the seeding fan 21, the seeds can quickly fall into the trench opened on the topsoil layer by the trenching shovel structure 36, realize wind-transported sowing, and achieve precision sowing.

[0037] In this embodiment, the suppression device 11 includes a suppression frame 27, a height-adjusting plate 29, a soil-covering suppression roller 28 and a scraper plate 38.

Through the telescopic movement of the hydraulic cylinder, the height of the sowing device 7, the furrowing device and the pressing device 11 can be adjusted to achieve an ideal sowing height.

[0039] In this embodiment, the number of the rotary tillage blades 32, the fertilizer shovel 37 and the trenching shovel structure 36 is set according to needs.

[0040] When the fertilizing device 4 is working, the tractor battery supplies power to the fertilizer discharge fan 3 and the fertilizer discharge motor. The fertilizer discharge fan 3 works, and the fertilizer discharge motor drives the fertilizer discharge wheel 42 to rotate.

The controller sends a control signal to the fertilizer discharge motor according to the speed information of the fertilizer discharge wheel 42 at the corresponding forward speed, controls the speed of the fertilizer discharge motor, and realizes rotation with the speed. The fertilizer discharge wheel 42 rotates to discharge the fertilizer to the fertilizer discharge port, and then enters the field through the fertilizer discharge pipe 5, the fertilizer delivery pipe 6 and the fertilizer shovel 37.

[0041] Accordingly, when the sowing device 7 is working, the forward speed of the tractor is measured by the speed radar and fed back to the controller. The controller sends a control signal to the seeding motor 25 according to the rotation speed information of the seeding wheel 40 at the corresponding forward speed, controls the rotation speed of the seeding motor 25, and realizes rotation with the speed. The seeding wheel 40 rotates to discharge the seeds into the distributor, and then enters the field through the seed delivery tube 8.

[0042] When working, driven by the tractor, the furrowing and ridging shovel 1 furrows forward to ridge the soil, and the rotary tiller 32 rotates to loosen the soil, and then the rear trimming shovel 31 moves forward to trim the ridge soil, which is convenient for subsequent covering of fertilizers; the fertilizer in the fertilizer storage box 17 is discharged to the fertilizer outlet pipe 5 through the fertilizer discharger, and the fertilizer discharge fan 3 works to blow the fertilizer into the fertilizer delivery pipe 6 to be sown in the cultivated furrow, and the rear dragging plate 30 can cover the sown fertilizer; during this period, the wind control lever 15 and the seeding wheel 40 can adjust the wind force and the amount of fertilizer falling at any time. When the sowing device 7 is running, the seeds in the seed storage box 22 fall into the seeding device 9, and the seeding motor 25 rotates to drive the seeding wheel 40 inside the seeding device 9 to rotate, and the seeds are discharged to the venturi tube 10, and then the sowing fan 21 blows the seeds from the venturi tube 10 into the distribution head 23. A plurality of seed delivery tubes 8 are installed on the distribution head 23, and the distribution head 23 distributes the seeds to each seed delivery tube 8, and then blows the seeds into the furrowing shovel structure 36 at the bottom and then falls into the furrow that has been cultivated. The rear suppression and covering roller covers the sown seeds while ensuring the furrowing of the cultivated land. Through the adjustment structure 34, the height of the sowing device 7 and the suppression device 11 at the rear can be adjusted according to the terrain. At the same time, the radar installed at the front end of the tractor can measure the speed to control the speed of the seeding wheel 40, the wind force of the fertilizer blower 3 and the sowing blower 21, and then control the precision of seeding and fertilizer discharge.

[0043] This embodiment uses a speed radar to measure speed in real time, and then controls the seeding motor 25, the fertilizer fan 3 and the sowing fan 21, so that the seed and fertilizer sowing accuracy is effectively controlled, saving fertilizer and seeds. It can improve the current problems of insufficient seed and fertilizer sowing accuracy, seed and fertilizer waste, and alleviate environmental pollution caused by excessive fertilization. In addition, the wide operating range can effectively improve the sowing efficiency.

[0044] The present invention aims at improving the structure of the device, and the control process of the controller is the prior art.

[0045] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
