Kaishan KG420B imhando yepamusoro, ine mhando dzakasiyana dzeDTH drilling rig yakagadzirirwa mabasa anorema ekuchera matombo nekuchera matombo. Iine nzira yakasarudzika yekupeta frame uye injini ine simba yeYuchai 4-cylinder, iyi rig yakavakwa kuti ipe kugadzikana kwakanyanya munzvimbo dzakadzika uye nzvimbo dzisina kuenzana. Ndiyo sarudzo yakakwana kune vanoshanda vanoda muchina wakavimbika, une torque refu unokwanisa kuchera maburi akakura munzvimbo dzakaoma dzezvemamiriro ekunze.

Modhi iyi imhando yepamusoro yakakosha muKG420 series, yakanyatsogadzirwa kuti ienderane nezvinodiwa nedhiziri ukuwo ichisimudzira simba remuchina. Injini yeYuchai YC4DK80-T302 ine simba rakasimba re58KW, zvichipa hwaro hwekuti rig iyi ikwanise kutenderera nekukurumidza uye torque. Shaanxi Kaishan akagadzira rig iyi kuti ikwanise kubata dhayamita yemaburi kubva pa90mm kusvika pa130mm, zvichiita kuti ive imwe yerig dzinoshanda zvakanyanya mukirasi yayo.

Chinhu chinoshamisa cheKG420B igwara rinopetwa pamwe chete nekuenzana kwegwara (±10°). Izvi zvinobvumira rig kuchengetedza nzvimbo yakaderera yegiravhiti uye kukweva kwakanaka kunyangwe pakukwira materu e30-degree. Kushandiswa kwemota yekufamba ine plunger kunoita kuti ifambise nesimba, nepo sisitimu ye4-wheel drive ichipa kubata kunodiwa pasi pematombo akaomarara. Dzimba dzakakora uye mhete dzekusimudza dzakabatanidzwa dzinowedzera kusimba kweindasitiri uye kutakurwa.

Kuboorwa kwesimbi kwavandudzika zvikuru kuburikidza nekushandisa silinda yekusimudza yakakura uye cheni yemashizha yakasimbiswa. Kuvandudzwa uku kunoshandura simba rekusimudza re25KN uye 3780mm, zvichiita kuti nyundo ishande zvakanaka uye kuti tsvimbo itarisirwe zvakanaka. Ne torque yepamusoro ye2000N·m uye kumhanya kusvika 140rpm, KG420B inogona kushanda nesimba kuburikidza nematombo akaoma (f=6-20) ichishandisa nyundo dze3″ kana 4″.

Sisitimu yeboom nebeam yerig iyi inopa kuchinjika kwakanyanya. Nekutenderera kwebeam kwe185° uye kutenderera kwe145°, vashandisi vanogona kusvika panzvimbo dzakaoma dzekuboorera zviri nyore. 900mm compensation feature inoita kuti gwara rekutungamira rirambe rakabata pasi, zvichideredza kudedera uye kuvandudza kurongeka kwemaburi. Maburi akatambanuka anogona kuboorwa pakakwirira kubva pa350mm kusvika 2750mm.

Kuti kuchera kushande zvakanaka, tinokurudzira kubatanidza KG420B nemacompressor eKaishan ane pressure high-pressure akadai seKSCY550-13, KSCY570/12-550/15, kana LGCY17/18-18/15T. Rig iyi yakakodzera kuchera migodhi yepakati nepakati kusvika yakakura, kuvaka migwagwa, uye mapurojekiti akasiyana-siyana ezvivakwa anoda kuchera kwakadzama uye kwakanyatsojeka kweDTH.
