[0002] Corn-soybean strip composite planting is a planting method that alternates corn and soybean in the field. When performing composite planting, a corn-soybean strip composite seeder is required. Corn seeds and soybean seeds are placed in corresponding silos respectively. The composite seeder is installed on the rear side of the tractor, and the baffle of the silo outlet is opened. The tractor drives the composite seeder to move. During the movement of the composite seeder, the row opener at the bottom of the composite seeder moves on the land, and the seeds in each silo fall down. The covering wheel at the rear side of the composite seeder moves. During the process, the soil is pushed to the seeds to achieve seed coverage. The row opener is mainly composed of a square rod and a row-opening plow fixed to the bottom of the square rod. The square rod is fixed in the square sleeve by bolts, the square sleeve is fixed to the front side of the square plate, and the square plate is fixed to the compound seeder by the cooperation of the U-shaped screw and the nut. The height of the row opener can be adjusted by loosening the bolts at the square sleeve, raising the row opener can reduce the row opening depth, lowering the row opener can increase the row opening depth, and the height of the row opener can be adjusted according to different usage requirements. After adjusting to the appropriate depth, tighten the bolts.

[0003] When the common corn-soybean strip-shaped composite planting row opener is in use, when the composite seeder is used to sow to the edge of the land in the area, there is a situation where the number of rows that can be opened at the edge of the land is less than the number of row openers installed at the bottom of the composite seeder. At this time, in order to prevent repeated opening of the land, the excess row openers need to be removed from the composite seeder. When removing, the nut on the U-shaped screw that fixes the row opener needs to be unscrewed, and then the row opener is removed from the composite seeder. The excess row openers are all removed in this way, and sowing can be carried out after removal. After sowing is completed, the multiple removed row openers need to be reinstalled on the composite seeder. The operation is cumbersome and inconvenient to use. Therefore, the present application provides a corn-soybean strip-shaped composite planting row opener to meet the needs. Utility Model Content
