The utility model relates to a seeding mechanism of a seeder, which comprises a frame, the upper part of which is sequentially connected with a four-bar linkage mechanism and a strong seeding metering device. A seed metering wheel is arranged in the strong seeding metering device, the seed metering wheel is installed on the seed metering shaft, the first sprocket is installed on the seed metering shaft, the bottom of the four-bar linkage mechanism is provided with a second sprocket, and the second sprocket is connected with the first sprocket through a chain. The upper end of the bar linkage mechanism is articulated to one side of the seed box, and the other side of the seed box is connected with the rack. The lower part of the rack is provided with stubble breaking discs, trenching discs, depth limiting wheels, compacting wheels and compacting wheels, which are installed at the lower part of the rack. The compacting wheels are connected with the rack through a cantilever. The depth limiting wheels are connected to the outer side of the lower part of the rack, and the trenching discs are located directly below the strong-impact seed metering device. The stubble disc is connected to the lower end of the frame. Deep-limiting wheel can ensure synchronization with the seed-throwing point, compacting wheel can press seeds into wet soil, and compactor can crush soil blocks. Compression after sowing is conducive to promoting seed germination.
【技术实现步骤摘要】
播种机的播种机构
本技术涉及播种器
,尤其是一种播种机的播种机构。
技术介绍
播种机是利用机械化、自动流水线,将种子点播在预制的型孔式的水平盘内,然后在开沟器开完沟,由肥箱施肥后,经导种管把种子排到沟里。它排种率高、周边型孔对种子粒型的适应性比较好。采用此播种机技术播出的种子,出苗整齐、便于机械化生产。但是现有的播种机播种的深度不同,且不能保证种子与土壤的紧密接触,最后的镇压效果不好,导致种子发芽率不高。
