Strip-shaped composite seeder for corn and soybeans

Abstract

The invention discloses a strip-shaped composite seeder for corn and soybeans. The strip-shaped composite seeder comprises a rack, seeding parts, driving parts, pressing parts, a fertilizing part, a stubble ploughing part and a transmission part, wherein the seeding parts, the driving parts, the fertilizing part and the transmission part are all mounted on the rack; the pressing parts are mountedon the seeding parts; the stubble ploughing part is mounted on the fertilizing part; and the transmission part is connected with a seed discharging part and the fertilizing part correspondingly. The strip-shaped composite seeder has the advantages that the soybean seeding parts are arranged in a front-back manner, so that the phenomenon that excessive weeds block the seeding parts to cause windingcan be avoided; the soybean pressing parts are hollow in the middle and solid on two sides, so that the pressing of the soybeans can be reduced while the pressing of the corn is ensured, and the soybeans can grow better; and the stubble ploughing part is mounted on the fertilizing part and is driven to rotate by power output of a tractor, so that the aims of small occupied space, high rotating speed, quick stubble ploughing and reduction of the overall weight of the seeder can be achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery manufacturing, in particular to a corn-soybean belt compound seeder for simultaneously sowing corn and soybeans. Background technique [0002] Corn is the crop with the highest total yield. The annual planting area of ​​corn in the world reaches 30 billion hectares and above, and the total output exceeds 1 billion tons. Soybean is the fourth largest grain crop in my country. With the rapid development of my country's aquaculture industry, the demand for soybeans is increasing. In 2014, the total soybean imports exceeded 70 million tons for the first time, a record high. Corn-soybean strip planting technology can increase land multiple cropping index, improve land utilization rate, and increase grain production. Under the intercropping mode, on the basis of ensuring corn production, an extra 80-150 kg of soybeans can be harvested per mu. Soybeans can also reduce the nitrogen content ...

AI Technical Summary

Problems solved by technology

Today, however, most corn and soybean planters are self-contained, unintegrated, and can be severely hampered by excessive crop residue or weeds from previous seasons in the field

At present, most seeders can only realize the function of simultaneous sowing or stubble removal, and the seeders that can perform both functions at the same time are not suitable for hilly and other areas due to their large size, so it is difficult to promote the seeder
