A corn-soybean strip compound seeder

Abstract

The invention discloses a corn-soybean strip compound seeder, which comprises a frame, a sowing part, a driving part, a pressing part, a fertilizing part, a stubble removal part and a transmission part; the sowing part, the driving part, the fertilization part and the transmission part are all It is installed on the frame, wherein the seeding part is equipped with a suppression part, and the fertilization part is equipped with a stubble removal part; the transmission part is respectively connected with the seeding part and the fertilization part. The present invention has the following advantages: soybean sowing parts are arranged in a front and rear form, which can prevent excessive weeds from clogging and entanglement between the sowing parts; the soybean pressing part is empty in the middle and solid on both sides, which can ensure the suppression of corn and reduce the impact on soybeans The suppressing makes it grow better; the stubble removal part is installed on the fertilization part, and the power output of the tractor is used to drive the rotation, which can achieve the purpose of small space occupation, fast speed, rapid stubble removal, and lightening the overall weight of the planter.

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
