Corn and soybean composite seeding machine

Abstract

The invention relates to agricultural machinery, in particular to a corn and soybean composite seeder. Comprising a machine frame, a fertilizing device, a fertilizing and ditching device, a corn seeding device, a soybean seeding device and a main transmission device, the fertilizing device is fixed to the middle of the top of the machine frame, the fertilizing and ditching device is located under the fertilizing device, and the corn seeding device and the soybean seeding device are both located behind the fertilizing device. The corn seeding devices are located on the left side and the right side of the rack, a plurality of soybean seeding devices which are arranged at intervals in the width direction of the rack are arranged between the corn seeding devices on the two sides, and the fertilizing device and the soybean seeding devices are in transmission connection with the main transmission device. The whole machine is coordinated, the requirement for planting row spacing of soybeans and corn is met, turning at the edge of a field is facilitated, the pressing strength of the corn and the soybeans is adjustable, the pressing strength of corn and soybean planting is met, and combined sowing of the soybeans and the corn is achieved.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a corn-soybean compound seeder. Background technique [0002] At present, there are only soybean and corn seeders with a single variety on the market. In the process of intercropping and compound planting of soybean and corn, a unified whole machine equipment is required to solve the inconsistency of the whole machine in the process of joint seeding of soybean and corn, and the difficulty of wide and narrow row spacing. It is difficult to meet and turn the land, and there is an urgent need for targeted and adaptable equipment to meet the requirements of simultaneous sowing of soybeans and corn. [0003] In addition, the crushing strength of the existing soybean after sowing is not high, and reasonable sowing equipment is needed to solve such problems. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to overcome the above-mentioned defects existing in the prior...

AI Technical Summary

Problems solved by technology

[0002] At present, there are only single varieties of soybean and corn planters on the market, and there is a lack of soybean and corn intercropping. In the process of compound planting, it is necessary to unite and unify the whole machine equipment to solve the problems of uncoordinated whole machines and difficult width and narrow row spacing in the process of soybean and corn joint planting. It is difficult to meet the turning point of the machine tools, and there is an urgent need for targeted and adaptable equipment to meet the requirements of simultaneous co-sowing of soybeans and corn.

[0003] In addition, the suppression strength of soybeans after sowing is not high, and reasonable sowing equipment is needed to solve such problems
