Simulation of hanging device of wheat no-tillage planter in lift course based on ADAMS;

Construction and gray evaluation of the performance index system of wheat no-tillage planter

Improvement and experiment on the device for separate application of fertilizer and seed for no-till wheat drill;

The author mainly stated the technical parameters and operation principle of the hinge implement of conservation tillage—2BM-9 model no-till seeder as its performance test,reliability trial and the application effect in this paper.

According to the technical requirements and the productive experiments of the no-till agriculture,this paper makes the improving design of the no-till seeder and its working parts,especially makes some breakthroughs in aspects of the four-bar linkage,the opener boot,and the stubble rotary knife,etc.

It is imperative to develop and produce the no-till seeder for the Conservation tillage technology in accordance with the promotion requirements.

A new 2BQMF-5 type of suction and fertilizer no-till planter was designed.

Based on the analysis on the requirements for no-till planter for mechanized protective tillage, formulation machine types, characteristic and researching situation of no-till planter.

The reciprocating powered-cutter wheat no-till planter,which has the functions of residue-cutting,seeding and bed-renovating,was designed based on the problems of residues blocking and seriously damaged bed shape during the planting of wheat in maize stubble coverage fields under the condition of permanent raised beds(PRB)in irrigation agricultural region of northwest China.
