When the holding height 200mm lower than sugarcane centroid, the sugarcane can not be windrowed outwards, and distance increase with the increasing of the holding height.

当甘蔗夹持高度低于甘蔗质心200mm以上时，甘蔗就不能够向外铺放，随着夹持高度的增加，甘蔗铺放距离减小。

Conducting investigations in the holding and conveying mechanism, studying windrowing quality and power under different movement parameters and structure parameter have theoretic and practical significance in order to provide reference for the design of sugarcane harvester.

本文采用圆弧导轨式柔性夹持输送装置的设计方案，通过对其的室内模拟试验来观察甘蔗夹持、输送的运动过程，并分析各运动参数、几何参数以及甘蔗生长状态对甘蔗输送质量、铺放质量和功率的影响。

Previous studies focused on cutting and lifting sugarcane stalks, the sugarcane stalks holding and conveying research was almost blank. Researching and designing new holding and conveying mechanism, providing the basis for the design of sugarcane harvester, reducing the plugging and breaking of sugarcane stalk, increasing windrowing quality, reducing power consumption, have important theoretical and practical significance.

以前的研究主要集中在甘蔗切割和扶起方面，对于甘蔗夹持输送机理的研究几乎是空白，研究设计新型的夹持输送机构，研究其工作机理，为甘蔗收割机的设计提供依据，减少甘蔗的堵塞和折断，提高铺放质量，降低功耗，具有重要的理论意义和实用意义。

The spindle selects enclosed rolling bearing for supporting; vertical and horizontal drag board are adopted with enclosed rolling rod drive; body guide ways are casted with abrasion-resistance iron quenched with super frequency and milled precisely, and all these contribute to a long-term processing precision and a long lifespan; 5.5KW motor serves as the main motor contribute to a stronger turning capacity and larger rotary speed range; Workpiece clamping is are adopted withed with spring collet, it can also be equipped with hydraulic chuck, four-spindle oil cylinder, pneumatic, hydraulic tail stock.

CK6232数控车床是一款高刚性封密数控车床，特别适宜粗精加工，整机造型稳重大方，全封闭护罩防护，主轴采用精密刚性轴承支撑，纵横向拖板采用精密滚珠丝杆传动，床身导轨采用耐磨铸铁铸造，经超音频淬火及精密磨削，能长期稳定的保证加工精度和使用寿命；主电机选用5.5KW 的电机，使主轴有更强的切削能力和转速范围；工件装夹方式选用弹簧夹头，也可按用户要求配置手动卡盘、液压卡盘，气压、液压尾座。

Vertical and horizontal power chuck is fixed on the bench of the chuck without rotation to clamp workpiece with hydraulic or air pressure drive. The chuck is widely applied in the production line or tube welding machine tool, grinding machine, drilling machine, milling machine, as well as numerical control machining center.

立卧式动力卡盘是指卡盘不旋转，固定在机床工作台上起夹持工件的作用，夹持动力以液压或气压驱动；该装置广泛应用在生产流水线上或管子焊接机床、磨床、钻床、铣床以及数控加工中心上。

It applies the air pressure collets,chuck or center to clamp the work-piece with table,and carries out the performance direct and indirect dividing,plate-slotting and various cam-curving.

利用主轴内大口径通孔，安装气动弹弹簧头，动力卡盘或顶尖，对转台装夹的工作进行辅助夹紧，实现等分的，不等分的连续的孔槽，曲面的加工，且达到较高的精度。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
