Bucket capacity ndiyo chiyero chehuwandu hwehuwandu hwezvinhu zvinogona kuiswa mukati memugomo we backhoe excavator.Kuwanda kweBucket kunogona kuyerwa musimba rekurohwa kana kuunganidzwa kwesimba sekutsanangurwa pazasi:
Struck capacity inotsanangurwa se: Huwandu hwehuwandu hwebhaketi mushure mekunge yarohwa pane ndege yekurova.Iyo ndege inorova inopfuura nepamusoro pemucheto kumashure kwebhakiti uye kucheka kwekucheka sezvakaratidzwa mumufananidzo 7.1 (a).Uku kurova kwesimba kunogona kuyerwa zvakananga kubva ku3D modhi yebackhoe bucket excavator.
Ukuwo kuverengerwa kwemurwi wemurwi kunoitwa nekutevera zviyero.Pasi rose zviyero zviviri zvinoshandiswa kuona huwandu hwakaunganidzwa, ndezvi: (i) SAE J296: "Mini excavator uye backhoe bucket volumetric rating", an American standard (Mehta Gaurav K., 2006), (Komatsu, 2006) (ii) CECE ( Komiti yeEuropean Construction Equipment) chiyero cheEurope (Mehta Gaurav K., 2006), (Komatsu, 2006).
Hututu hwesimba hunotsanangurwa se: Huwandu hwesimba rakarohwa pamwe nehuwandu hwezvinhu zvakawandisa zvakatutirwa pamugomo pa1: 1 kona yekuzorora (maererano neSAE) kana pa1: 2 kona yekuzorora (maererano neECCE), sezvinoratidzwa mumufananidzo 7.1 (b).Izvi hazvireve kuti badza rinofanira kutakura bhaketi rakanangana nemafungiro aya, kana kuti zvinhu zvese zvinongove ne1:1 kana 1:2 kona yekuzorora.
Sezvinoonekwa kubva kuFig. 7.1 iyo yakatutirwa huwandu Vh inogona kupihwa se:
Vh=Vs+Ve ....(7.1)
Ipo, Vs ndiyo simba rakarohwa, uye Ve ndiyo yakawandisa zvinhu simba rakatutirwa pamwe pa1: 1 kana pa1: 2 angle yekuzorora sezvakaratidzwa muFig. 7.1 (b).
Chekutanga, kubva Fig. 7.2 akarova simba Vs equation ichaunzwa, zvino nekushandisa nzira mbiri SAE uye CECE, maviri equation yeakawandisa zvinhu vhoriyamu kana kugona Ve ichaunzwa kubva Fig. 7.2.Pakupedzisira bhaketi rakatutirwa huwandu hunogona kuwanikwa kubva kuequation (7.1).

- Tsananguro yemazwi akashandiswa mumufananidzo 7.2 ndeiyi inotevera:
- LB: Kuvhurika kwebhaketi, kuyerwa kubva pakucheka kusvika kumagumo kwebhaketi reshure rendiro.
- Wc: Kucheka upamhi, kuyerwa pamusoro pemazino kana mativi ekucheka (ona kuti iyo 3D modhi yebhaketi yakatsanangurwa mune ino thesis ndeyebasa rakareruka rekuvaka basa, saka macheki epadivi haana kubatanidzwa mumuenzaniso wedu).
- WB: Kufara kweBhakiti, kuyerwa pamusoro pemativi ebhaketi pamuromo wezasi pasina mazino evacheki veparutivi vakanamirwa (saka izvi hazvizovewo zvakakosha 108 parameter yemhando yakarongwa ye3D yebhaketi sezvo isina chero mativi ekucheka).
- Wf: Mukati mehupamhi kumberi, kuyerwa pakucheka kumucheto kana mativi ekudzivirira.
- Wr: Mukati mehupamhi kumashure, kuyerwa kune yakamanikana chikamu kumashure kwebhaketi.
- PArea: Side profile nzvimbo yebhaketi, yakasungwa nemukati contour uye ndege inorova yebhaketi.
Mufananidzo 7.3 unoratidza maparameter akakosha ekuverenga huwandu hwebhakiti yeiyo yakarongwa 3D modhi yebhaketi.Iko kuverenga kwakaitwa kwakavakirwa paSAE chiyero sezvo chiyero ichi chinogamuchirwa pasi rose uye kushandiswa.
