Ngā Paerewa Kōwhiringa mō ngā Mekameka Roera i roto i ngā Mīhini Hauhake Ahuwhenua
Hei wāhanga matua e hono ana i te tuku hiko me te whakahaere o te mīhini hauhake, ko te whiriwhiri i te mekameka roera e whakatau tika ana i te pai o te mahi a te taputapu, te tere o te rahunga, me te roa o te ratonga. Mō ngā kaihokohoko e aro ana ki te mākete o te ao, ko te matatau ki ngā paerewa whiriwhiri pūtaiao ehara i te mea ka taea te taurite tika i ngā hiahia o te kiritaki engari ka whakaitihia hoki ngā utu i muri i te hoko me te hanga i tētahi ingoa ngaio—ina koa i roto i ngā āhuatanga whakaputa ahuwhenua nui e "he mea nui te wā." Mā te whiriwhiri hē kotahi ka arahi ki te kotinga katoa a te kiritaki, ā, ka pā ki te whakawhirinaki me te mahi tahi. Ka tīmata tēnei tuhinga mai i ngā āhuatanga whakahaere o ngā mīhini hauhake, ka wetewetehia ngā āhuatanga matua, ngā mahi whaihua, me ngā whakaaro hē noa omekameka roerate whiriwhiri, me te whakarato i ngā aratohu hangarau whai hua ki ngā kaihokohoko.
I. Ngā Tawhā Whakahaere o te Kaitātari Matua me Mārama i mua i te Kōwhiringa
He uaua, he rerekē hoki te taiao mahi a ngā mīhini hauhake ahuwhenua. Ko ngā hua rerekē (witi, kānga, raihi), te kaha mahi (te rohe mahi o ia rā mō ia mīhini), me te āhuarangi ā-rohe (ua, puehu, pāmahana teitei) katoa e pā nui ana ki ngā whakaritenga mahi o te mekameka roera. I mua i te kōwhiringa, me whakaū e toru ngā tawhā matua ki te kiritaki kia kore ai e "kōwhiria i runga i te wheako."
Te Kawenga Tūturu e Tukuna ana: He mea nui kia wehewehea te "kawenga whakatauranga" me te "kawenga pānga." I te wā e whakahaerehia ana te mīhini hauhake, ko ngā āhuatanga pēnei i te tūtakitanga o te pane ki ngā mea mārō (ngā kōhatu, ngā puranga taru) me te whakawhāiti ohorere rānei o te mekameka kawe ka taea te whakaputa pānga e 2-3 ngā wā o te kawenga whakatauranga. Nō reira, me whiriwhiri te tauira i runga i te kawenga pānga, kaua ko te kawenga e rite ana ki te mana whakatauranga kua tohua i roto i te pukapuka taputapu.
Tere Whakahaere o te Mekameka: He rerekē rawa ngā tere o ngā wāhanga rerekē. Hei tauira, ko te mekameka taraiwa pane hauhake e mahi ana i te 500-800 rpm, ko te tere mekameka o te pūnaha kawe he 200-400 rpm. Ko te tere ake ka hua ake he tere ake te kaha o te porotītaha me te pakaru o te mekameka; nō reira, me aro nui ki ngā tauira mekameka tino tika, māmā hoki.
Ngā Āhuatanga o te Taiao Whakahaere: E toru ngā āhuatanga matua e whakaarohia ana: te puehu (hei tauira, te hauhake witi i ngā rohe raki), te haumākū nui (hei tauira, ngā pāmu raihi i ngā rohe tonga), me te aroaro o ngā matū waikura (hei tauira, te wai mai i te kakau witi kuru i roto i ngā mīhini hauhake). Ko ngā taiao pakari ka nui ake ngā tono mō ngā rauemi o te mekameka, te maimoatanga mata, me te hanganga hiri. II. Ngā Paerewa Matua e Whā mō te Kōwhiri i ngā Mekameka Roera mō ngā Mīhini Hauhake Ahuwhenua
I runga i ngā tawhā whakahaere o runga ake nei, ka taea e ngā kaihokohoko te whakawhāiti haere i te whānuitanga o ngā kōwhiringa mā te whakamahi i ngā paerewa e whā e whai ake nei hei whakatau i te tauira mekameka roera e tika ana.
1. Te Whakataurite Utaina: "Te Tauwehe Haumaru" hei Tohu Matua
Ko te kawenga te pūtake matua mō te kōwhiringa. Me tatau te tauwehenga haumaru mā te "kawenga pānga tuturu ÷ kawenga hihiri kua whakatauria e te mekameka" kia kore ai te mekameka e whati i raro i ngā āhuatanga mahi tino kino.
Te Mātāpono Uara Tauwehe Haumaru: Mō ngā mīhini hauhake witi/raihi, e taunakihia ana kia ≥1.8 te tauwehe haumaru; mō ngā mīhini hauhake kānga (he nui ake te kawenga kakau witi), e taunakihia ana kia ≥2.2. Mena he nui te kaha o te mahi a te kiritaki (hei tauira, neke atu i te 12 hāora mahi ia rā), me whakanui ake mā te 0.3-0.5.
Ngā Whakatūpato: Āta karohia te "kōwhiringa taumaha rawa" (arā, he nui rawa te tauwehenga haumaru), ki te kore ka piki ake te taumaha me te utu o te mekameka, ā, ka kore pea e pai te hononga i waenga i te mekameka me te pīkau, ka tere ake te pakaru.
2. Te Whakataurite Tere: Te Hononga ki te Tika o te Mekameka me ngā Whakaritenga Whakahinuhinu
Ka pā tika te tere ki te whakaputa wera me te tere o te kakahu o te mekameka. Me whiriwhiri te kounga tika o te mekameka me te otinga whakahinuhinu i runga i te tere.
Taumata Tika: Mō ngā tere > 600 rpm, me whakarite ngā mekameka ISO 60 (tino tika) hei whakaiti i te wiri me te haruru i te wā e whakamahia ana; mō ngā tere < 400 rpm, ka taea te whiriwhiri i ngā mekameka ISO 80 (tino tika) hei whakataurite i te utu me te mahi.
Te Hononga Whakahinuhinu: Me whakamahi ngā mekameka tere-rahi i te hinu ārai-kākahu pāmahana teitei (pērā i te hinu kei roto i te lithium), ā, me kī atu ki ngā kaihoko kia whakapotohia te huringa whakahinuhinu (me whakakī anō i ia 8 hāora) hei karo i te "waku maroke" nā te kore e ranea te whakahinuhinu.
3. Te Whakarerekētanga Taiao: Te Kōwhiringa Rauemi me te Maimoatanga Mata
Ko ngā taiao whakahaere rerekē me whiriwhiri i ngā rauemi mekameka me ngā tukanga maimoatanga mata kia tika ai te whakatau i te ātete o te mekameka ki te waikura me te poke.
Taiao Whakahaere | Rauemi e Manakohia ana | Tukanga Maimoatanga Mata | Ngā Painga Matua
Taiao Pūpū, Maroke | Rino Hanganga Koranu 40MnB | Whakakā me te Whakaweto + Whakapūtātanga | He pakari te mata, he ātete ki te puehu me te kakahu
Teitei o te haumākū, te taiao ua | Kowiri tira 304 (Utaina māmā) | Maimoatanga korehau | Ārai waikura kaha, he pai mō ngā mahi mara raihi
Utaina Taumaha + Taiao Waikura | Rino Hanganga Koranu 20CrMnTi | Paninga Pirau + Hiri | Taurite te kaha me te ātete ki te waikura, he pai mō ngā mīhini hauhake kānga
4. Te Whakataurite Hanganga: Hononga Tuturu ki ngā Sprockets Harvester
Me tino ōrite ngā tawhā hanganga o te mekameka roera ki ngā pīkau o te mīhini katote; ki te kore, ka kore e pai te hononga o te whatunga, ka kore e tika te haruru, ka pakaru rānei.
Ngā Tawhā Taurite Matua: Te teitei (te ine tino hira o te mekameka, me tino ōrite ki te teitei o te porotiti, me te hapa ≤0.05mm), Te Diameter o te Roera (me hototahi ki te rahi o te awaawa niho porotiti), Te Whānui o te Pito o Roto (kia kore ai te mekameka e "rere ke i waenganui" i te porotiti). Ngā Whakaritenga Hanganga Motuhake: Mena he pūnaha kawe tere-rahi te mīhini hauhake a te kiritaki, ka taea te tūtohu i tētahi mekameka roera me ngā pereti ārahi hei ārai i te peka o te mekameka taha i te wā e mahi ana. Mena he maha ngā poke o te taiao mahi, ka taea te whiriwhiri i tētahi mekameka roera hiri (me ngā mowhiti hiri kua hangaia) hei whakaiti i te urunga o ngā poke ki roto i ngā roera.
III. Te Mahi Kōwhiri Kaihokohoko: 3 Ngā Hipanga: Mai i te Whakawhitiwhiti Kōrero ki te Whakaū
I muri i te mōhio ki ngā paerewa, me kōrero ki te kiritaki mā te tukanga paerewa hei whakarite i te tika o ngā mōhiohio kōwhiringa me te karo i ngā tautohetohe i muri i te hoko i muri mai.
Hipanga 1: Tikina ngā Taipitopito Taputapu a te Kaihoko Tonoa te waitohu, te tauira o te mīhini hauhake (hei tauira, John Deere S780, Kubota PRO988) me ngā wāhanga tono motuhake (te puku pane, te mekameka kawe, te pūnaha patu witi) mai i te kiritaki. Whakaūtia ngā whakatakotoranga mekameka taketake o te wāhanga mā te pukapuka taputapu, mā ngā mōhiohio rānei a te kaihanga hei pūtake mō te kōwhiringa.
Hipanga 2: Tāpirihia he Pātai Āhua Whakahaere Taipitopito Whakamahia he pātai māmā hei whakamārama i ngā tawhā matua, pēnei i: "He aha ngā hua e hauhaketia ana e tō mīhini hauhake?" "He aha te roa o te wā mahi ia rā mō ia mīhini?" "He mara raihi, he whenua maroke rānei te rohe mahi?" Whakawhitihia ngā hiahia koretake ki ngā tawhā hangarau motuhake. Hipanga 3: Hoatu he Kōwhiringa Otinga me ngā Whakatūpato Mōrearea ki ngā kaihoko. Hoatu ki ngā kaihoko kia 1-2 ngā otinga e tika ana (hei tauira, te otinga tuatahi + te otinga iti ake te utu), me te whakaatu mārama i ngā horopaki me ngā whakatūpato e tika ana mō ia otinga. Hei tauira: "He pai te mekameka o te Otinga 1 mō ngā mahi kānga taumaha, engari me whakahinuhinu i ia 6 hāora; he 15% te iti ake o te Otinga 2, engari e taunakitia ana mō ngā mahi witi māmā anake."
IV. Ngā Whakaaro Hē o te Kōwhiringa: 3 Ngā Mahanga me Ārai e ngā Kaihokohoko
Whakaaro Hē 1: Te Arotahi ki te Pitch Anake, te Whakahāwea i Ētahi Atu Tawhā. E whakapono ana ētahi kaihokohoko "ki te tika te pitch, ka taea te whakamahi," engari ka warewarehia te taurite o te diameter roera me te whānui o te hononga o roto, ka mutu ka piri te mekameka i te wā e mau ana te sprocket, ā, i ngā wā kino, ka pakaru te sprocket. Me whakamahara ki ngā kaihoko: he "taurite katoa" te mekameka, ā, me rite ngā tawhā hanganga katoa ki te mekameka taketake.
Whakaaro Hē 2: Te Tūtohu Matapo i ngā "Mekameka Utu Nui." Tērā pea kāore ngā mekameka utu nui e tutuki i ngā hiahia o te kiritaki. Hei tauira, mā te tūtohu i ngā mekameka kowiri tira mō ngā mara witi maroke ka piki ake ngā utu a te kiritaki, ā, kāore te kowiri tira i te kaha rite ki te maitai koranu, ka whakapoto pea i tōna roanga o te ora. Ko te otinga "tino whai hua" me tūtohu i runga i ngā āhuatanga whakahaere, kaua i te otinga "tino utu nui".
Whakaaro Hē 3: Te kore aro ki ngā tikanga tāutanga me te tiaki. Mena kāore he kaimahi tiaki ngaio i te wāhi o te kiritaki, me tūtohu he mekameka he "kore tiaki" ngā āhuatanga (pēnei i te mekameka kati me te mowhiti hiri), ā, me whakangawari ake ngā whakaritenga whakahinuhinu. Mena he iti te wāhi tāutanga o ngā taputapu a te kiritaki, me whakaū te radius piko iti rawa o te mekameka kia kore ai e rahua te tāutanga.
