QY42R型遥控割草机性能测试

Performance Test of QY42R Robotic Lawnmower

为解决包括老式果园在内的农业农村领域狭小区域的杂草收割问题,参照标准GB/T 10938—2008《旋转割草机》、GB/T 14176—2012《林业机械以汽油机为动力的便携式割灌机和割草机》,对QY42R型遥控割草机进行性能测试。结果表明,QY42R型遥控割草机性能较好,其中割幅利用系数为99.8%,割净率达到99.1%,基本无漏割情况发生;其纯作业效率0.152 hm2/h,为人工割草作业的4.2倍以上;作业成本较人工割草作业节省48%以上。

In order to solve problems of weed cutting in the narrow area of agricultural and rural areas including old orchard,according to standard GB/T 10938—2008 "rotary mowers" and GB/T 14176—2012 "forestry machinery,gasoline powered portable brush cutters and grass trimmers",performance of QY42R robotic lawnmower was tested. Results showed that QY42R robotic lawnmower has good performance,in which utilization coefficient of cutting range was 99.8%,net cutting rate could reach 99.1%,and there was basically no missing cutting. Its pure operation efficiency was 0.152 hm~2/h,which was about 4.2 times of that of manual mowing. Meanwhile,operating cost was more than 48% lower than that of manual mowing.
