The utility model discloses a to the arable land environment that the straw covered, consequently the sorghum seeder must have and prevents stifled subassembly, then install the back at the stubble-breaking ware with a pair of grass poking wheel, its effect is toward both sides clearance straw stubble and prevent that the furrow opener from blockking up. Meanwhile, a corrugated disc is designed to be matched as a stubble breaking and chopping mechanism, and the stubble breaking and chopping mechanism has the characteristics of fast and effective stubble breaking and residual straw and weed cutting. Because no-tillage plots are not prepared, and a plurality of harder clods with larger volume exist, the random corrugated disc can also break the clods. When designing a seed furrow opener, a double-disc type opener is selected. The double-disc type furrow opener has small requirement on the environment of cultivated land, and can have good working effect on common cultivated land which is leveled by rotary tillage and no-tillage sowing cultivated land which is covered by more straws. That is, firstly, the corrugated disk is used for ditching the land for the first time, and then the double-disk type ditcher is used for ditching for the second time to ditch the seed ditch.
The air-suction seed metering device 11 is formed by buckling a left shell 20 and a right shell 21 and fixing the left shell and the right shell by bolts 22, as shown in figure 5, a groove is formed at the upper half part in the left shell 20 to form a negative pressure chamber 23, a rubber gasket 24 is seated on the side opening of the negative pressure chamber 23, a rubber ring 37 is embedded in the center of the left shell 20, and a seed metering disc 25 compresses the rubber gasket 24 and is fixed with the left shell 20 and the right shell 21 into a whole through a seed metering shaft 26; suction holes 27 are uniformly distributed on the seed metering disc 25, the rear ends of the suction holes 27 are communicated with the negative pressure chamber 23, a through hole 28 is arranged outside the right shell 21, one end of a seed scraping plate 29 is fixed with one end of the right shell 21 through a bolt 36, and the body of the seed scraping plate is arranged in the shell and is abutted against the seed metering disc 25; the auxiliary transmission shaft 34 is in transmission with the seed shaft 26 on the seed disk 25 through a chain II 35 to drive the seed disk 25 to rotate.
