coal unloader
解釋
卸煤機-
The frozen coal destruction is the tension stress destroys, and establish the frozen coal cutting model in this foundation, obtains the cutting force, feeding force, tooth spacing according to the smallest energy principle. bring forward a rotary drilling mothod to unload the frozen coal, the broken ability is strong, without frozen depth limits, then obtains this machine working parameters, has combined this method with a grab and determined the plane of vehicle - carried rotary drilling movable coal - unloader
凍煤破壞是拉應力破壞，在此基礎上建立了凍煤的切削模型，根據最小能量原理得到截割力，進給力和截齒間距的計算公式，分析得到截割力與切削厚度成正比，隨著前角的增大而減小;截齒最優截距與截齒尺寸有關且與切屑厚度成正比;進給力隨著截齒前角增大而增大的規律。 -

Langfang jihua - trade fuels management company limited was established in 2006, has been two years of coal sales history, major cities headquarters in beijing have large freight yard with a total area of 160, 447 square meters, each package of road freight yard with all the machinery coal unloader missing, the coal and coal transport system, sprinkler irrigation equipment, are equipped with dedicated rail lines
廊坊冀華通貿燃料經營有限公司成立於2006年，至今已有2年煤炭銷售歷史，總公司在北京各大城市均有大型貨場，總面積160447平方米，每個貨場均擁有整套行進的機械缺卸煤、配煤系統和煤炭轉運、噴灌設備，均配有鐵路專用線。 -
In winter the outside temperature is - 15 ~ - 30, the wet coal freezes seriously in transportation. the frozen coal thick is about 400mm, sometimes freezes to a whole one, the unloading work is extremely difficult, affects the turnover of coal train, possessing rail cars and the railway, makes the railway transport strength not be fully displayed. it has created national manpower, financial resource loss, but in domestic and foreign, the development of movable frozen coal unloader is the blank
在冬季北方室外平均氣溫在- 15oc ~ - 30oc ，濕煤在外運的過程中凍結現象嚴重，凍層厚在400mm左右，有時整車凍實，作業十分困難，影響運煤列車的周轉，造成壓車，壓線現象，使鐵路運力得不到正常的發揮，造成了國家人力，財力的損失，而國內外對于移動式卸凍煤機械的研製也是空白，為此急需研製一種能夠卸凍煤的可移動式卸煤機。
