In this paper, the typical P-30B rock rake bucket loading machine for the study vehicles, the establishment of a working device mathematical model of the movement, the use of AutoCAD and other graphics software and its working bodies, the working principle of the overall design. Specific tasks include the following aspects: 1: Taiwan car design of the overall program: including the choice of the overall program, sports, the dynamic calculation, the composition of the work of agencies as well as the initial program development. Determine the choice of the initial components and the parameters set, drawing the design plans trolley. 2: the design of cars the structure: including all components to determine the basic structure and some parameters. 3: Taiwan, the design of car parts: includes frame, axle components, latches, springs and other components meet the definition, rendering some parts diagram, according to parts in order to choose the right parts to complete the design of components. 4: Taiwan car design of the parts: the main parts including the identification, parts of the calculation of strength as well as some parts of the mapping components, such as wheels, axle and so on. 5: test of the overall design and verification, sum up the design ideas and complete the overall design of the trolley.

Driving system is an important consisting part of engineering machine. The driving system has not only greater transfer power requirement but also higher efficiency and longer life time rather than working system. In addition, it request excellent capability in shifting speed, differing speed, changing output rotation direction as well as reversing transmission power. In this case, Which transmission way should be used, how to better satisfy the requirement of varieties of engineering driving systems are always researching task for machinery engineering industry. Especially for the recent years, the constructions in China have been expanding rapidly, such as transportation, energy etc. The market demand of engineering machinery enhances greatly, meanwhile it will face the worse operation environment and the challenge which is caused by the complicated working environment. Those matters may promote the deep investigation of driving system.

在下跌铣，虽然降息首先在于它具有切屑厚度，逐步减少到零。这有助于消除饲料标志着目前的情况了铣削，因此更好的表面光洁度。攀登铣削还允许更多的资讯和更长的每颗牙齿之间regrinds切削寿命比传统铣削。 优势： （一）适应机器薄，难以举行部分工件以来被迫对表或持有设备的刀具。 （二）工作需要不能钳制紧密。 （三）一致并行和规模可以维持，尤其是在薄部分。 （四）它可用于在突破的边缘工件是不能容忍的。 （五）它需要多达20 ％的权力，可以切断对用此方法。 （六）它可以用来切断股票时，或当铣削深，薄插槽。 缺点： （一）不能使用，除非机器的反弹消除和表臂已收紧。 （二）它不能被用于加工铸件或热轧，因为硬外尺度将损害刀。 7.4铣作业 7.4.1工作控股 铣床表具有高精度并行T型槽沿纵轴。工件因此，可以直接安装在桌子上使用这些T型槽。或者各种工作举行器件可用于举行工件，根据工件的种类和类型的铣削有许多工作要做。 副主席是最常见的形式举行的工作设备用于举行小型和定期工件。副主席是安装在桌子上使用T -插槽。各种各样的副颌骨，可适应不同工件的几何形状。 通用夹头用于举行一轮工件加工结束插槽，样条等。赛程是最常见的形式举行的工作中使用的生产设备铣削行动。它们被用来降低设置时间，并增加地点准确度和可重复性。 对于大型和不规则工件，夹在不同的形状，可显示Fig.7.16 。这些夹子可以用来在若干方面。某些方法中显示Fig.7.17 。但是，必须注意，以确保不改变工件的作用下切削力。夹紧力不应过高，因为这可能扭曲工件。 7.4.2铣削调校 根据这种情况，大量的各种铣削方法已经制定出来。这些方法描述了以下几行。他们主要是根据公约，而不是任何科学依据。
