Center pivot sprinkler (yomwe nthawi zina imatchedwa central pivot sprinkler), yotchedwanso sprinkler yozungulira yamagetsi, pointer type sprinkler etc., ndi njira yothirira mbewu momwe zida zimazungulira mozungulira pivot ndipo mbewu zimathiriridwa ndi zokonkha.Njira zothirira zapakati-pivot ndizopindulitsa chifukwa chotha kugwiritsa ntchito madzi moyenera ndikukulitsa zokolola za famu.Machitidwewa amagwira ntchito kwambiri m'minda yayikulu.
Zokolola zoyeneras: nyemba, chimanga, tirigu, mbatata, beet shuga, chimanga ndi mbewu zina ndalama.
Pakatikati yothandizira shaft kumapeto kwa sprinkler ndi yokhazikika, ndipo chowaza chotsalacho chimayenda mozungulira kumapeto komwe kumayendetsedwa ndi mota.Kupyolera mu mawonekedwe kumapeto kwa Central Nthambi kutsinde, madzi amapopedwa mmwamba kuchokera mtsinje kapena bwino ndi kutumizidwa kwa chitoliro madzi pa sprinkler truss, ndiyeno anatumiza kumunda mwa sprinkler kuzindikira basi ulimi wothirira.
Malo ozungulira omwe ali pa pivot amathiriridwa, nthawi zambiri amapanga ndondomeko yozungulira mu mbewu pamene ikuwoneka kuchokera pamwamba.
Kuthirira kwapakati-pivot kumagwiritsa ntchito ntchito yochepa kusiyana ndi njira zina zambiri zothirira pamtunda, monga kuthirira mumizere.
Ilinso ndi ndalama zotsika mtengo kuposa njira zothirira pansi zomwe zimafuna kukumba ngalande.
Komanso, kuthirira kwapakati-pivot kumatha kuchepetsa kuchuluka kwa nthaka.
Zimathandiza kuchepetsa kuthamanga kwa madzi ndi kukokoloka kwa nthaka komwe kungachitike ndi ulimi wothirira pansi.
Kusalima pang'ono kumalimbikitsanso kuti zotsalira za mbewu ziwolere m'nthaka.Zimachepetsanso kuphatikizika kwa nthaka.
Ma pivots apakatikati nthawi zambiri amakhala osakwana 500 metres (1,600 ft) m'litali (ozungulira radius) ndipo kukula kodziwika kwambiri kumakhala makina ofikira mamita 400 (1⁄4 mi), omwe amakhala pafupifupi mahekitala 50 (maekala 125) a malo.

Pogwiritsa ntchito mtundu womwewo wa mota ya UMC VODAR, kusinthasintha kwake ndi chilengedwe, kuzizira kwambiri ndi kutentha sikukhudzidwa, kulephera kutsika, kutsika kwachangu, kotetezeka komanso kodalirika.
Ndi ntchito chitetezo, kwa kusakhazikika voteji ndi zinthu mochulukira, sizidzawoneka fuse, wosweka waya chodabwitsa.
Pogwiritsa ntchito chipolopolo cha aluminium alloy, chimatha kusindikiza popanda madzi.
Galimoto yosindikizidwa bwino, palibe kutayikira kwamafuta, moyo wautali wautumiki.
Landirani mtundu womwewo wa VODAR wochepetsera wa UMC, womwe ndi woyenera pamikhalidwe yosiyanasiyana, yotetezeka komanso yodalirika.
Kuyika kwamtundu wa bokosi ndi chisindikizo chamafuta, kumateteza bwino kutayikira kwamafuta.
Chitetezo chakunja chopanda fumbi pazolowera ndi zotulutsa.
Chipinda chokulitsa chachitsulo chosapanga dzimbiri, pogwiritsa ntchito mafuta opanikizika kwambiri, chitetezo chamafuta a nyongolotsi ndichodabwitsa.
Kulumikizana kwapakatikati kumatengera njira yolumikizirana ndi mpira ndi pabowo, ndipo machubu a mpira ndi pabowo amalumikizidwa ndi masilindala a mphira, omwe amakhala ndi kusinthasintha kwa mtunda ndipo amathandizira kwambiri kukwera.
Mpira mutu mwachindunji welded kwa lalifupi mtanda chitoliro thupi, amene kwambiri kumawonjezera mphamvu ndi angathe kulimbana ndi kumangika mphamvu ya zitsulo nyengo yozizira ndi kupewa kugwa kwa zida.
Nsanjayo ndi V-woboola pakati, amene amathandiza bwino truss ndi bwino kwambiri bata la zipangizo.
Kukonzekera kawiri kumagwiritsidwa ntchito polumikiza mwendo wa nsanja ndi chitoliro, zomwe zimathandizira kwambiri kukhazikika kwa zida.
Chitolirocho chimapangidwa ndi Q235B, Φ168*3, chokhala ndi mankhwala okhuthala kuti chikhale chokhazikika, chosagwira ntchito, chotsika kutentha komanso cholimba.
nyumba zonse zitsulo ndi otentha-kuviika kanasonkhezereka mu amapita pambuyo processing ndi kuwotcherera, ndi makulidwe a kanasonkhezereka wosanjikiza ndi 0.15mm, amene ndi apamwamba kwambiri kuposa muyezo makampani, ndi mkulu dzimbiri kukana ndi moyo utumiki wa zaka zoposa 20.
Pambuyo pokonza, chubu chachikulu chilichonse chimayesedwa ndi makina ojambulira mphamvu zake zowotcherera kuti zitsimikizire kuyenerera kwa 100%.
Dongosolo lowongolera limatenga ukadaulo wa American Pierce, womwe ndi wokhazikika komanso wodalirika wokhala ndi ntchito zambiri.
Zida zazikulu zamagetsi zimagwiritsa ntchito mitundu ya American HoneyWell ndi French Schneider kuti zitsimikizire kuti zida zikuyenda bwino.
Ndi ntchito yoletsa mvula, makiyi amakhala ndi chithandizo cha fumbi, chomwe chimatalikitsa moyo wautumiki.
Asanachoke pafakitale, kuyezetsa kolimba kumachitika kuti zitsimikizire kukhazikika kwa dongosolo lonse lowongolera.
