Technical Field

[0001] The utility model relates to the technical field related to agriculture, in particular to a corn and soybean belt-shaped composite double-row planting seeder. Background Art

[0002] The rotation of corn and soybeans can not only effectively utilize resources such as land, temperature and water, but also regulate soil nutrients and improve soil fertility, promote the diversity of soil microbial communities, prevent the spread of pests and diseases, and improve soil health, thereby increasing the output per unit area. When planting, a double-row planting seeder is needed;

[0003] In the human-propelled double-row seeder disclosed in the publication number CN202335223U, a front connecting rod, a seed box, a rear connecting rod, and a tension bolt are connected to the machine connecting piece to ensure smooth operation. A handrail frame is connected under the front connecting rod, and a handrail frame is connected to the rear connecting rod. To open furrows and divide soil with light resistance, a limit wheel, an oblique knife furrow opener, and a double-piece drum-type ground wheel are connected under the seed box to achieve different row spacing standards for different crops. The tension screw is opened, and the machine connecting piece is retracted and released on the front connecting rod and the rear connecting rod to achieve the purpose of smooth operation, furrowing and dividing soil, and standard row spacing;

[0004] However, the above scheme still has the following problems during use: during use, when adjusting the planting and sowing spacing, it is done by screwing the bolts one by one, which is time-consuming and labor-intensive. The threads are severely worn during the frequent screwing process and are prone to slippage, which in turn affects the stability of the composite double-row planting and seeder during use.

[0005] Therefore, we proposed a corn and soybean strip composite double-row planting seeder to solve the above-mentioned problems. Utility Model Content
