A corn-soybean combined seeding device

Abstract

This invention relates to the field of seeder technology, and more particularly to a combined corn and soybean seeding device, comprising a mounting frame, which is bolted to an agricultural machine. A switching mechanism is mounted on the front of the mounting frame, and several plowshares are mounted from left to right on the bottom of the switching mechanism. These plowshares create planting furrows when plowing the land. A planting mechanism is mounted on the front of the switching mechanism. The switching mechanism adjusts the distance between the plowshares and the planting mechanism, thereby changing the planting row spacing to simultaneously meet the planting needs of corn and soybeans. Several covering mechanisms are mounted from left to right on the outer wall of the planting mechanism. This device eliminates the need for multiple dedicated seeders, effectively reducing equipment purchase and transportation costs, and significantly improving the convenience and efficiency of field operations. It automatically adapts to the different seed sizes and sowing quantities required for corn and soybeans, precisely controlling the number of seeds sown per hill, avoiding the problems of over-sowing requiring thinning or under-sowing requiring re-sowing, thus improving sowing accuracy and seedling uniformity.
