播种机

In addition, the depth of the extensive planter beds could not exceed 6-8, yet had to allow for layers of waterproofing and drainage and proper cultural requirements of the sedums.

此外，该深度的广泛播种机病床不能超过6月8日，但已让层的防水及排水和适当的，文化的要求，该sedums 。

This caused him to lose his balance and land on the edge of one of the planters.

这使得他失去了平衡，一下子降落到其中一个播种机的边沿上。

The key to that is the research and design of no-tillage planters.

机械化保护性耕作技术应用和推广的关键是免耕播种机的研制。

The lift course of hanging device on wheat no-tillage planter was simulated by using the software of ADAMS. Some important parameters were obtained such as height of the working part relative to ground, the distance between the working part and the rear wheel of tractor, the angle of road pass and the force of hanging point, etc. The key parameters of the hanging device and its best working parameter of hanging device were found out through optimization simulation. Simulation results showed that suspension point had minimum force when variable DV_1 and DV_2 gained corresponding maximum and minimum at scope of structure limit.

应用ADAMS软件对小麦免耕播种机悬挂机构提升过程进行了动态仿真，得到了工作部件的位置高度、工作部件与拖拉机后轮之间的间距、路面通过角以及悬挂点的受力等参数，找到了悬挂机构的关键参数，通过优化仿真，得到了悬挂机构的最佳工作参数，仿真结果表明，设计变量DV_2、DV_3在结构受限范围内分别取其最大值和最小值，悬挂机构悬挂点受力最小。

On the basis of the dynamic field plant distribution model with the seed drop tube of precision planter the whole moving process of seeds on the seed drop tube was described in this paper.

在精密播种机接输种管后田间植株分布动态模型的基础上，利用随机、统计和精密播种等理论，描述了种子在输种管内运动的全过程。

It includes seeder, rice planter, planting machine, mulchlaying machine, compound seeder and seedling preparation machinery.

包括播作机、水稻插秧机、栽植机、地膜覆盖机、复式播种机、秧苗准备机械。

The reciprocating powered-cutter wheat no-till planter, which has the functions of residue-cutting, seeding and bed-renovating, was designed based on the problems of residues blocking and seriously damaged bed shape during the planting of wheat in maize stubble coverage fields under the condition of permanent raised beds in irrigation agricultural region of northwest China.

针对西北灌溉农业区固定垄保护性耕作条件下玉米秸秆覆盖地垄作免耕播种小麦存在的机具堵塞、垄形破坏等问题，设计了一种集切茬、播种和修垄于一体的往复切刀式小麦固定垄免耕播种机。

In order to reduce the seeding absent of seed drill, ameliorate the quality of mechanical work and improve the level of automation, the automatic reseeding monitoring system of seed drill was developed, which was based on single chip microcomputer AT89C51, the core of monitoring system.

为减少播种机的漏播现象，提高播种机械作业质量和自动化水平，研制了基于单片机的播种机工况自动补播式监控系统。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
