Whole machine profile modeling of whole type floating profile modeling mechanism,side deep fertilizer opener of obtuse angle chisel shape,precision seed metering device of combined internal cell bore,and covering soil part of front back separating character are applied in the machine,...

该机采用整体式浮动仿形机构整机仿形，钝角凿形侧深施肥开沟器，组合内窝孔式精密排种器，前后分置式八字型覆土器，其原理新颖、传动可靠、使用调整方便，既可垄播、平播，又可按传统行距和大垄双行播种，播种质量好。

Sowing fertilization monomer form of installations, and round configuration of the increase in broadcast rear rack can be planted to ensure that the land side; the use of knife-type trencher stubble breaking, and buried a small resistance, with stubble in the soil is not cultivated to the same place deep application of fertilizer and sowing operations.

播种施肥装置采用单体形式，地轮配置在播幅之内机架后方，能保证播种到地边；采用刀式破茬开沟器，入土阻力小，能在带麦茬未耕土壤里进行同位深施肥和播种作业。

This example focuses on the design seeder platoon of vehicles, fertilization devices, trenching vehicles structure.

本例着重对播种机排种器、排肥器、开沟器、覆土器以及镇压轮等结构进行设计选择。

Motibity changed by gear-box in direction and rotate speed is transferred to the blade axis on the right side to drive the blade axis. blade axis'parameter, blade assembling frame and blade assembling means are ascertained. The load and movement of the blade axis are analyzed. And the best blade rotate speed is ascertained. According to the request of no-tillage soil, the appropriate furrow openers are chosen. They are staggered and assembled in two rows .According to the sliding cutting request, the crucial parts of the anti-blocking——the sliding cutting blade, its edge curve is analyzed and designed in principle. The academic curve function is gotten. Combined with working practice and technics request, the blade's figuration parameter is designed, 65Mn is chosen as the material for blades. The working load is analyzed. And the intension of the sliding cutting is analyzed and checked with ANSYS software. At last, the spring rack of the suppress wheal is analyzed in principle. The theory and parameter of designing the spring rack of the suppress wheal. Experiment indicated that the anti-blocking capability of this anti-blocking equipment was excellent.

设计出适合此防堵装置的动力传输方案，动力经变速箱变向变速后从右侧传给刀轴，驱使刀片切割秸秆；确定出了刀轴的参数、刀片的安装结构和安装方法，对刀轴的受力和运动进行了分析，确定出了刀轴最佳转速；根据免耕地的要求，选择恰当的开沟器，并采用双排错位安装的办法，避免了"瓶颈"现象的发生；根据滑切的要求对此防堵装置的关键部件——滑切刀片的刃口曲线进行了理论分析和设计，得到了刀刃的理论曲线方程；结合生产实践及工艺要求，设计出刀片的外形参数，选择65Mn作为刀片的材料；分析和计算了刀片在工作中承受的载荷，运用ANSYS 软件对滑切刀片的强度进行了分析校核；最后对镇压轮的弹簧支架结构进行了理论分析，提出了设计镇压轮弹簧支架的理论和参数依据。

This planter used the way combining the vertical residue-cutting by powered cutter and horizontal residue-cutting by knife shaped opener to solve blocking. Furthermore, the columniform and cultivated-type plough was adopted to renovate the beds.

该机通过利用动力切刀往复垂直切茬和刀刃型开沟器水平切茬相结合的方式实现秸秆防堵，同时采用圆柱熟地型修垄犁解决垄形修复问题。

Furrowing opener is one of important components in seeding and fertilizing. They often work in the soil with high moisture content. Soil adhesion on the surface of furrow opener increase the drag resistance considerably, makes the opened furrow irregular and depth of furrow not uniform, influences the performance of seed and, sometimes, makes them stop working. All these phenomena will influence the seeding quality.

开沟器是播种机、施肥机上的重要部件，在含水量较大的土壤中工作时，土壤粘附在工作表面，改变了表面形状，导致牵引阻力增大，开出的沟形不整齐，使种子在沟中的深度不一致，影响播种质量，严重时使出苗率降低10%，甚至使其无法作业。

Hoe trenching shovel-type multi-zone for the two crops a year post-harvest wheat stubble iron corn planting area in a year a cooked corn straw mulch on the ground there are certain difficulties in use.

锄铲式开沟器多用于一年两熟区小麦收获后玉米的铁茬播种，在一年一熟区的玉米秸秆覆盖地上使用有一定的困难。

Eight-shaped double-disk sub-grass ditching device installed in the two pre-installed as "eight-shaped" arrangement of the concave disc of crushed corn stalks after the strong role of the sub-grass.

八字形双圆盘分草装置在开沟器前安装两个成&八字形&布置的凹面圆盘，对粉碎后的玉米秸秆有很强的分草排堵作用。

The experiment results approve that the opener has good performance of anti-blocking, but it needs biggish positive press. When the bob-weight is 350 kg and the gross weight is 570 kg, the performances of penetrating depth and cutting stubbles are excellent in trials, which makes sure that the opener is worth of research.

从田间试验结果来看，该开沟器有很好防堵性能，但需要较大正压力，试验当整机配重为350kg，总重570kg时其入土深度、破茬性能都能很好的满足要求，有进一步研究开发的价值。
