【摘要】 为了解决现有茶园除草人工除草效率低下、化学除草农残超标、密植茶园行距较小等问题,设计了一种小型自走式茶园除草机。详细介绍了机具的基本结构、工作原理和性能参数,重点对该机动力、除草轮和传动系统进行了选配设计,最后通过4因素3水平的正交试验,找出影响除草效果的因素。试验结果表明:对除草率的影响程度大小依次为除草轮转速、除草深度、除草刀个数、机具前进速度;综合功率消耗的情况,得出除草效果最优组合为除草轮转速为350r/min、机具前进速度0.8m/s、除草深度30mm、除草刀个数为6;此时的除草率为80.7%,能够达到较好的除草和控草效果。更多还原

【Abstract】 In order to solve artificially weeding with low efficiency,pesticide residues exceeded,and close planting tea garden with smaller Row spacing,Small Self- propelled Tea garden weeder was designed. The basic structure,working principle and parameters of the machine were introduced in detail. The emphasis is focused on the design of the mobile power,the weeding wheel and the transmission system. Finally through the orthogonal experiment of " 4 factor 3 level",factors affecting the weeding effect were found. Test results show that the degree of the effect of weeding rate as follows:weed number of wheel speed,depth of weeding,weeding knife,machine speed. Integrated power consumption at the same time,the optimal combination of the weeding effect is: the rotation speed of the weeding wheel with 350 r / min,implement speed with 0. 8m / s,weeding depth with 30 mm,6 weed cutters. At this time the weeding rate was 80. 7%,it can achieve better weeding and weed control effect.更多还原
