Description

Air-blowing type monomer Technical Field The utility model relates to the field of sowing, in particular to an air-blowing type monomer. Background The planter uses crop seeds as planting machines for seeding. In the working process of the existing seeder, ditching can be carried out on the land, seeds are discharged into the ditches through the seed metering device, and accordingly seeding is completed. But this kind of mode still needs the manual work to at the seeder seeding in-process, the emergence of phenomena such as card kind jam appears very easily, and some mountain area ground unevenness still need the manual work to its ground level, and the seeder just can work, thereby greatly increased staff's work load, and seeding inefficiency. Therefore, a need exists for a seed sowing device which can realize continuous operation of ditching, sowing and earthing, has high sowing operation speed, good adaptability of the seed sowing device to seeds and consistent sowing depth Disclosure of Invention The present utility model aims to solve at least to some extent one of the technical problems in the above-described technology. In order to achieve the aim, the first aspect of the utility model provides an air-blowing type monomer which comprises a profiling four-bar mechanism, a corrugated plate, a depth limiting wheel, a pressing wheel, a fertilizer box, an air-blowing type seed box, a PTO transmission shaft, a rack, a seed sowing device, a seed pressing wheel, a seed sowing guide pipe and a ditching plate, The four-bar mechanism is arranged at the front end of the frame, the corrugated disc is arranged on the frame and is positioned at the bottom of the four-bar mechanism, two depth wheels are arranged at the bottom of the frame in a V shape and are positioned at one side of the corrugated disc, the pressing wheel is arranged at the tail of the frame and is positioned at the other side of the depth wheels, the fertilizer opening box is arranged at the top of the frame and is positioned right above the pressing wheel, the air-blowing seed box is arranged at the top of the frame and is positioned at one side of the fertilizer opening box, the seed sowing device is arranged in the middle of the frame and is positioned at the bottom of the air-blowing seed box, one end of a PTO transmission shaft is connected with a driving end, the other end of the PTO transmission shaft is connected with the seed sowing device, the pressing wheel is rotatably arranged in the middle of the two depth wheels, one end of a seed sowing guide pipe is connected with the seed sowing device, the other end of the PTO transmission shaft extends to one side of the seed pressing wheel, the two ditching discs are respectively arranged at the opposite ends of the two limit wheels, the PTO transmission shaft drives the seed sowing device to press the seed sowing wheel through the sowing guide pipe when working, and the PTO transmission shaft compresses seeds into the ditches, and the soil is discharged by the pressing wheel. In addition, the air-blown monomer proposed in the utility model can also have the following additional technical characteristics: Further, the corrugated plate, the ditching plate and the seed pressing wheel are respectively arranged on the frame through mounting frames, and the mounting frames are respectively connected with the profiling four-bar mechanism. Further, a feed opening is formed in the bottom of the fertilizer box. Further, the bottom of the air-blowing seed box is connected with the feed inlet of the seed sowing device. Further, a seed metering disc is arranged in the seed metering device, and a plurality of seed holes are formed in the seed metering disc along the circumference at equal intervals. According to the air-blown type single body, redundant weeds can be removed through the corrugated disc, the ditching disc is used for ditching, the seed sowing device discharges seeds in the air-blown type seed box into the seed ditches through the seed sowing guide pipe, and finally the soil is compacted through the compacting wheel to finish sowing.
