1GSZ-350型灭茬旋耕联合整地机的设计与试验

为了适应大马力拖拉机对配套农机具的需求，在分析研究中小型单一和组合作业模式整地机的基础上，设计研制出一种集灭茬、旋耕和深松于一体的宽幅联合整地机，并进行了单一和联合作业的试验。试验表明，该机具在作业时能够充分发挥大马力拖拉机的作业效率，减少拖拉机的功率消耗，节能约14.3%；机具配置的灭茬刀、深松铲和旋耕刀排列合理，保墒效果明显，碎土率和灭茬率高达95%。该机属于高效节能型机具，为研究大型农机具提供了参考。

Design and test of 1GSZ-350 stubble-breaking and rotary tilling combined cultivating machine

In order to meet the needs of agricultural implements matched with high-powered tractors, a broad width combined cultivating machine was design based on single and combined work of cultivating machines. The combined cultivating machine had the functions of stubble-breaking, rotary tillage and subsoiling. Single works and combined work were carried out. The experimental results showed that the machine could give full play to a operation efficiency of high-power tractor when working. The designed machine could reduce power consumption of tractor, and energy saving was about 14.3%. The arrangement of stubble-breaking blade, deep-shovel and rotary tilling blade was reasonable, and soil moisture conservation efficiency was obvious. The ratios of pulverizing soil and stubble-breaking were above 95%. The designed machine belongs to energy saving of high efficiency machinery, and provides reference for studying on large agricultural implements.
