when the fertilizer in the fertilizing box 11 is sufficient, the conveying motor 60 acts, the conveying shaft 29 rotates, the first spiral blade 62 and the second spiral blade 30 convey the mixed fertilizer to the outward direction of the left end and the right end of the fertilizing pipe, so that the fertilizer is contained in the length direction of the fertilizing box 11, the fertilizer is mixed while the fertilizer with different elements is applied, and the operation efficiency is further improved; the height position of the pesticide application main pipe 35 is adjusted, the height adjusting rod 32 moves up and down along the fixing sleeve 40, and when the position of the pesticide application main pipe 35 is adjusted to the required height, the height adjusting rod 32 and the fixing sleeve 40 are fixedly connected together by using the connecting pin 4133; when the machine works in a farmland, the first lifting linear driver 22 and the second lifting linear driver 37 simultaneously and reversely act, the front supporting wheel 8 and the rear supporting wheel 17 are lifted, the front supporting wheel 8 and the rear supporting wheel 17 are far away from the farmland ground, the first lifting linear driver 22 and the second lifting linear driver 37 stop acting, the ground attaching roller 20 rolls forwards and simultaneously the ditching ring 21 ditches, the electric seeder 56 and the electric fertilizer discharger 55 start to act, the front rotating shaft 44 rotates, the first brush 43 is driven by the front rotating shaft 44 to rotate, the first brush 43 brushes down soil adhered on the ground attaching roller 20 and throws the soil outwards, the surface of the ground attaching roller 20 is kept relatively flat all the time, the resistance of the ground attaching roller 20 in continuous forward rotation is reduced, the electric seeder 56 discharges seeds into a seed ditch, the electric fertilizer discharger 55 applies soil beside the seed ditch, and nutrients of fertilizer are transmitted to the seeds through the soil, the press wheel 46 presses and flattens the sown field, the liquid pump is opened, the liquid medicine in the medicine storage box 31 is pumped into the pesticide application main pipe 35, the pesticide application spray head 34 is opened, and the liquid medicine is applied to the farmlands after fertilizer application; the invention mixes fertilizer and applies fertilizer at the same time, thereby improving the operating efficiency; when the vehicle runs normally on the road, the front supporting wheels 8 and the rear supporting wheels 17 provide stable running ground for the operation structure, a frame on a tractor is not needed to provide large supporting force for the operation structure, and the structure is more reliable; the disc plough 18 firstly ditches the field for the first time, the cutter shaft 53 rotates to drive the ditching cutter 58 to rotate, the ditching cutter 58 ditches again at the position where the disc plough 18 ditches, and the ditch arranging device 2 ditches again at the position where the ditching cutter 58 ditches, so that the ditches are arranged to be flat while the ditching resistance is reduced; the first brush 43 and the second brush 47 can respectively brush down and throw away the clay stuck on the ground roller 20 and the press wheel 46, so as to reduce the forward rotation resistance of the ground roller 20 and the press wheel 46; the ground-attaching roller 20 and the press wheel 46 improve a stable operation plane for the electric seeder 56, the electric fertilizer apparatus 55 and the pesticide application nozzle 34, so that seeds can accurately fall into the opened seed ditches, and the effects of seeding, fertilizing and pesticide application are better; can be applied to the work of seeding and fertilizing crops.
