Abstract: This paper designed a symmetrical spiral row-sorting of the straw device (SSRSD) under the condition that the no-till anti-blocking knife cut and chopped the straw to guarantee the machine’s passing capacity. The row-sorting blade (RB) of the symmetrical spiral mechanism (SSM) pushed the straw that fell into the straw hopper to the non-sowing area on both sides of the sowing belt and played the role of row-sorting the straw. Based on a theoretical analysis of the relationship between the material-bearing capacity limit of the SSM and the straw mulching quantity (SMQ) in the actual operating area, the critical parameters of the SSM and its value ranges were determined. The results show that the average straw removing rate (SRR) of the no-till planter with the SSRSD was 87.98%, and the passing capacity of the machine was great. Compared with the no-till planter without the SSRSD, the average SRR was increased by 20.7%.
