Ukufaneleka okuhlobene kwamathayi omoya kanye namathrekhi ensimbi avamile asetshenziswa kugandaganda wezolimo kuyacutshungulwa kanye nekesi lenzelwa amandlaamathrekhi enjolobaukuhlanganisa izinzuzo zombili. Kubikwa izivivinyo ezimbili lapho ukusebenza okukhangayo kwamathrekhi enjoloba kwaqhathaniswa nalokho kwamasondo okushayela ugandaganda.

Esokuqala kwaba ukuqhathanisa phakathi kwethrekhi yerabha ye-friction drive yokwakhiwa okulula okufakwe emotweni yokuhlola, kanye nesondo elivamile lokushayela ugandaganda. Ithrekhi ikhiqize cishe ukudonsa okungu-25% ngaphezu kwesondo.

Ukuhlolwa kwesibili kwaba ukuqhathanisa phakathi kokuncanedumper iloliegijima kumathrekhi enjoloba kanye nogandaganda ojwayelekile onesisindo esifanayo. Lokhu kubonise ukuthi amathrekhi enjoloba asekelwe ngokwanele angaveza izici zokusebenza ezifana nalezo zamathrekhi ensimbi. Iloli lakhiqiza ukudonsa kabili kukagandaganda onamasondo ngendlela efanayo ehehayo futhi labangela ukuba kunciphe ukugqwala emhlabathini othambile.

I-Abstract (2)

Ngokwesiko, ogandaganda bakhelwe amathrekhi noma amasondo, namathrekhi ikakhulukazi ogandaganda abasindayo abanamandla amakhulu. Namuhla, kungenzeka ukubuyisela kabusha amayunithi ethrekhi amane ahlukene kugandaganda ovamile wezolimo, okwenza amathuba athakazelisayo kwezolimo. Inhloso yocwaningo lwamanje bekuwukuqhathanisa ukuminyana kwenhlabathi nokudonsa amathrekhi, amasondo awodwa namasondo amabili afakwe ohlotsheni lukagandaganda olufanayo.

Izilinganiso zenziwa enhlabathini yobumba emibili (i-Eutric Cambisols) eSweden ngo-2009, kusetshenziswa ugandaganda ongu-85 kW onesisindo esingama-7700 kg. Isistimu yethrekhi yenjoloba ibihlanganisa amathrekhi amane abekwe kuma-ekseli amasondo avamile kagandaganda. Izingcindezi ezilinganisiwe zazifana kumathrekhi namasondo amabili kukho konke ukujula okufundwayo (15, 30 kanye no-50 cm), kodwa bekuphakeme kakhulu kumasondo awodwa kukho konke ukujula. Ukulingisa izingcindezi zenhlabathi kuhlotshaniswa eduze namanani akalwayo amathrekhi namasondo amabili, kodwa ukucindezelwa kwenhlabathi okulinganiselwe endaweni engaphezulu uma kuqhathaniswa namanani akalwayo esondo elilodwa.

PHELA

Esigxile kukho ukuhlanganisa nokwenza ngcono izinga eliphezulu kanye nokulungiswa kweizinto ezikhona, okwamanje qhubeka ukhiqiza imikhiqizo emisha ukuze uhlangabezane nezidingo ezihlukile zamakhasimende ngentengo ephansi yasefekthri I-China Construction Machinery Parts PC200-6 PC220-6 Excavator Spare Parts Track Roller Guard 20y-30-31160, Umqondo wenhlangano yethu “Ubuqotho, Isivinini, Izinkonzo , kanye Nokwaneliseka”. Sizolandela lo mqondo futhi sithole ukugcwaliseka okwengeziwe nokungeziwe kwamakhasimende.
