中文摘要:为了减小深松机的耕作阻力和拖拉机的动力消耗,增强深松机对不同类型土壤的适用性,设计了弹簧预紧力可调式自激振动深松机。在机具工作过程中,通过自激振动单元的振动作用,可有效减小深松机的牵引阻力;通过弹簧预紧力调节机构可改变弹簧的预紧力,以适应不同物理特性的土壤,获得理想的深松效果。田间试验表明在保证耕深的前提下,合适的弹簧预紧力可有效减小机具的耕作阻力。为了测试该深松机的减阻性能,设计了2.5、3.2、4.0km/h 3种作业速度和250、300、350mm 3种深松深度,进行了两因素三水平的全因素试验,试验结果表明:在不同作业速度与深松深度下,与非振动深松机相比,该深松机均能有效减小牵引阻力,减阻比为10.30%~22.65%;对不同作业速度和深松深度下的振动深松牵引阻力和非振动牵引阻力进行了方差分析。结果表明作业速度、耕作深度和机具类型对深公机工作阻力均有显著性影响,在不同作业速度下,由于自激振动单元的减阻作用,随着耕作深度的增加,振动深松牵引阻力增加速度小于非振动深松。

Abstract:In order to reduce working resistance and power consumption of subsoiler, and improve the applicability to different soil, 1SZ-600 self excited vibration subsoiler characterized by adjustable spring pre tightening force was designed. The main part of the self excited vibrating subsoiler was tension spring, parameters of the spring were determined through subsoiler overall structure and springs location. Working resistance reduction was achieved by self excitation vibration unit. The pre tightening force of spring was changeable according to soil mechanical properties. Field experiment was conducted in Guan County, Hebei Province. Experimental factors included working depth of 250mm, 300mm and 350mm, operating speed of 2.5km/h, 3.2km/h and 4.0km/h. Results showed that to ensure the premise of deep tillage, selecting appropriate spring preload can effectively reduce the traction resistance. 〖JP2〗The draft resistance was decreased by 19.26%, 15.43% and 22.65% at working depth of 25cm, 30cm and 35cm 〖JP〗with working speed of 2.5km/h, respectively. When the working speed was 4km/h, draft resistance was decreased by 10.3%, 13.9% and 21.4%, respectively. Traction resistance reduction was obvious with higher working speed and it was decreased by 10.30%~22.65% compared with non vibrating subsoiler at any speeds and working depths. Variance analysis was conducted to ensure the significant influence of test factors. Results showed that working speed, tillage depth and machine structures had significant influence on the traction resistance. The increase rate of the traction resistance of vibration was less than that of non vibration with the increase of tillage depth at different operating speeds due to drag reduction of a self excited vibration unit.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
