New com­bine har­vester pro­to­types: Less main­te­nance and high­er reliability

Mod­ern com­bine har­vesters are the giants of agri­cul­ture. At har­vest time they are in con­tin­u­ous oper­a­tion and ensure that grain, corn, rape and oth­er field crops can be har­vest­ed effi­cient­ly. To do this, the com­bine sep­a­rates the valu­able grain from the stalks ful­ly auto­mat­i­cal­ly and in sev­er­al inte­grat­ed operations.

In the devel­op­ment of com­bine har­vesters, the goal of effi­cient har­vest­ing is para­mount. Due to the giv­en depen­den­cy on the weath­er, cer­tain time win­dows arise which must be used inten­sive­ly, espe­cial­ly dur­ing the har­vest­ing sea­son. Cur­rent com­bine har­vesters can weigh over 30 tonnes and achieve a work­ing width of over twelve metres, which sig­nif­i­cant­ly increas­es har­vest­ing per­for­mance. A con­sid­er­able increase in effi­cien­cy has been achieved by increas­ing the cut­ting width. Nev­er­the­less, the ques­tion remains open as to whether there are any tech­ni­cal inno­va­tions in com­bine har­vesters and for­age har­vesters in addi­tion to changes in size.

In the pro­to­type devel­op­ment of com­bine har­vesters, the replace­ment of the mate­ri­als used in the machine opens up a lot of unused poten­tial. New think­ing in mate­r­i­al selec­tion and the replace­ment of entire mod­ules or com­po­nents lead to many advantages:

Dura­bil­i­ty and dura­bil­i­ty of com­po­nents and mod­ules reduce the risk of fail­ure and make har­vest­ing more predictable.

Silen­tium Dri­ve – the qui­et inno­va­tion for the mod­ern com­bine harvester

For the var­i­ous work steps, the har­vest­ed crop must be trans­port­ed in the com­bine har­vester. “Silen­tium Dri­ve”, the new inno­v­a­tive con­vey­or sys­tem for com­bine har­vester feed­er chan­nels with rub­ber fab­ric belts and cam dri­ve elim­i­nates one of the main sources of noise in the com­bine – the unpleas­ant­ly loud clash­ing of chain and box-shaped con­vey­or shaft, which is com­mon­place in con­ven­tion­al­ly equipped com­bines, has come to an end thanks to our inno­va­tion. The Silen­tium Dri­ve sys­tem can be installed in any com­bine harvester.

Increase trans­port speed in the ele­va­tor and reduce maintenance

There is much more poten­tial in com­bine har­vesters for opti­mi­sa­tion through appro­pri­ate mate­r­i­al selec­tion. Our com­pa­nies Broeke­ma, Artemis and Jäger Gum­mi und Kun­st­stoff pre­sent­ed a new solu­tion for the ele­va­tor in the grain tank area at Agritech­ni­ca 2017. A rub­ber belt with high-strength rein­forc­ing inserts and very low elon­ga­tion replaces the pre­vi­ous­ly used steel chain when trans­port­ing the grain into the grain tank. This has made high­er speeds and increased through­put pos­si­ble. Thanks to the syn­chro­nous prop­er­ties of the sys­tem, more than 30 kW of pow­er can also be trans­mit­ted with this belt solu­tion to down­stream units such as dis­tri­b­u­tion augers in the grain tank.

Com­bine har­vester prod­uct development

Engi­neers from var­i­ous agri­cul­tur­al machin­ery man­u­fac­tur­ers work every day to opti­mise their machines for the var­i­ous appli­ca­tions and cli­mat­ic con­di­tions. As experts in the use of rub­ber and plas­tics, we active­ly sup­port devel­op­ment projects with­in the frame­work of devel­op­ment part­ner­ships. Indi­vid­ual devel­op­ment and the devel­op­ment of pro­to­types for com­bine har­vesters is the rule here. We start prod­uct opti­mi­sa­tions or new devel­op­ments as a joint project and lead them to suc­cess togeth­er with you!

Our new­ly devel­oped com­po­nents and mod­ules made of rub­ber or plas­tic for com­bine har­vesters are clear­ly supe­ri­or to the pre­vi­ous­ly used steel solu­tions in terms of dura­bil­i­ty and flex­i­bil­i­ty. Often the respec­tive com­po­nent is com­plete­ly redesigned accord­ing to the cur­rent require­ments of the indus­try.
The reli­a­bil­i­ty of the machines is ensured by the assem­blies we have devel­oped through high abra­sion resis­tance as well as durability.

For this pur­pose, the JÄGER Group devel­ops indi­vid­ual pro­to­types togeth­er with the com­bine har­vester man­u­fac­tur­ers. With­in the scope of field tests, these pre-series mod­els prove under the usu­al har­vest­ing con­di­tions that they are clear­ly supe­ri­or to the com­bine har­vesters used so far. We reg­u­lar­ly analyse how the new com­po­nents and mod­ules per­form in direct com­par­i­son with the pre­vi­ous ver­sions. In the prac­ti­cal tests, the lab­o­ra­to­ry results of the mate­r­i­al test­ing are val­i­dat­ed once again under typ­i­cal oper­at­ing conditions.

Prod­uct devel­op­ment for the life cycle of components 

Our holis­tic devel­op­ment approach includes the entire life cycle of prod­ucts, mod­ules and com­po­nents. This also includes the avail­abil­i­ty of spare parts and the replace­ment time of assem­blies. Even the instal­la­tion and assem­bly of spare parts are test­ed and eval­u­at­ed. A lot of time can be saved here by devel­op­ing instal­la­tion sets with a well thought-out com­bi­na­tion of indi­vid­ual parts.
