Crawler rabara tracknthawi zambiri ndi chimodzi mwazinthu zomwe zimawonongeka mosavuta pazofukula. Kodi ayenera kuchita chiyani kuti atalikitse moyo wawo wautumiki ndi kuchepetsa ndalama zosinthira? Pansipa, tikuwonetsa mfundo zazikuluzikulu zokulitsa moyo wautumiki wa ma track of excavator.

1. Mukakhala dothi ndi miyalanjira za excavator, ngodya pakati pa chofukula chokumba ndi mkono wa ndowa iyenera kusinthidwa kuti ikhale mkati mwa 90 ° ~ 110 °; Kenaka, ikani pansi pa chidebecho pansi ndikuzungulira mbali imodzi ya njanjiyi poyimitsa kangapo kuti muchotse nthaka kapena miyala mkati mwa njanjiyo. Kenako, gwiritsani ntchito boom kuti mutsitse nyimboyo kubwerera pansi. Mofananamo, gwiritsani ntchito mbali ina ya njanji.

2. Poyenda pa zofukula, ndi bwino kusankha msewu wathyathyathya kapena nthaka pamtunda momwe mungathere, ndipo makinawo sayenera kusuntha pafupipafupi; Mukayenda mtunda wautali, yesani kugwiritsa ntchito ngolo yoyendetsa ndipo pewani kusintha chofukula kuzungulira dera lalikulu; Pokwera malo otsetsereka, sikoyenera kukhala otsetsereka kwambiri. Pokwera potsetsereka, njirayo ingatalikitsidwe kuti muchedwetse njirayo komanso kuti njanjiyo isatambasulidwe ndi kukoka.

3. Potembenuza chofukula, mkono wofukula ndi mkono wa ndowa uyenera kusinthidwa kuti ukhale ndi ngodya ya 90 ° ~ 110 °, ndipo bwalo la pansi la ndowa liyenera kukanikizidwa pansi. Njira ziwiri zomwe zili kutsogolo kwa chofufutira ziyenera kukwezedwa kuti zikhale 10 cm ~ 20 cm kuchokera pansi, ndiyeno chofufutira chiyenera kuyendetsedwa kumbali imodzi ya njanji. Panthawi imodzimodziyo, chofukulacho chiyenera kuyendetsedwa kuti chibwerere mmbuyo, kotero kuti wofukula akhoza kutembenukira (ngati chofukula chitembenukira kumanzere, njira yoyenera iyenera kuyendetsedwa kuti isunthe, ndipo chowongolera chozungulira chiyenera kuyendetsedwa kuti chitembenukire kumanja). Ngati cholinga sichingakwaniritsidwe kamodzi, mutha kuyigwiritsanso ntchito pogwiritsa ntchito njirayi mpaka cholingacho chikwaniritsidwa. Kuchita zimenezi kungachepetse mikangano pakati panjanji ya rabarandi nthaka ndi kukana kwa msewu, zomwe zimapangitsa kuti njirayo isawonongeke.

4. Panthawi yomanga migodi, apron iyenera kukhala yosalala. Pofukula miyala yokhala ndi tinthu tating'ono tosiyanasiyana, apuloni iyenera kudzazidwa ndi tinthu tating'ono ta miyala yosweka kapena ufa wamwala kapena dothi. The apuloni lathyathyathya amatha kuonetsetsa kuti njanji zofukula ndi wofanana kupsyinjika ndipo osati mosavuta kuwonongeka.

5. Posamalira makinawo, kugwedezeka kwa njanji kuyenera kuyang'aniridwa, kuthamanga kwabwino kwa njanji kuyenera kusamalidwa, ndipo silinda yamagetsi iyenera kutenthedwa mwamsanga. Mukayang'ana, choyamba musunthire makinawo kutsogolo kwa mtunda wa pafupifupi mamita 4 ndikuyimitsa.

Kuchita bwino ndiye chinsinsi chokulitsa moyo wautumiki wanyimbo za rabara za excavator.
