摘 要: | 果树行间距一般比株间距大,可以利用割草机械直接进行除草作业,但是果树株间的杂草就不能很好的用割草机进行机械化作业清除。文章在江苏泰兴烨佳梨园、沛县聚英阁苹果园和睢宁官山楸树园对F.US-UFO型果园避障割草机开展田间试验,通过对收草质量、割幅、割茬高度、漏割率、避障损伤率、避障割草高度与行间高度最大差、最短避障距离的测定,测试机具作业性能;通过对使用可靠性系数、平均故障间隔时间、班次小时生产率、劳动生产率和单位面积耗油量的测定,测试其田间生产性能。试验结果表明:F.US-UFO型果园避障割草机既能完成行间割草作业也能完成株间割草作业。果园行间坡度越小,园间路面越平坦,果树株行距越大,割草机作业质量越高。割草机工作效率为0.49 hm~2/h,单位面积耗油量为11.41 kg/hm~2。

Experimental study on F.US UFO mower for avoiding obstacles in orchards |

Abstract: | The spacing between fruit trees is generally larger than the spacing between plants, which can be directly weeded by lawnmowers, but the weeds between fruit trees cannot be removed by mechanized lawnmower operation. In this paper, a field experiment was carried out on F.US UFO mower in Yejia Pear Orchard in Taixing Jiangsu Province, Juyingge apple orchard in Peixian County, and Guanshan Catania tree garden in Suining County. The operating performance of the machine was tested by measuring the quality of harvesting grass, cutting width, stubble height, missing rate, obstacle avoidance damage rate, maximum difference between obstacle avoidance height and row height, and shortest obstacle avoidance distance. The field performance was tested using the reliability coefficient, mean time between failures, shift hour productivity, labor productivity, and oil consumption per unit area. The experimental result showed that the F.US UFO orchard obstacle avoidance mower can accomplish the interrow and interplant mowing. The smaller the slope between orchard rows, the flatter the road surface between orchard, and the larger the row spacing of fruit trees, the higher the operation quality of the lawnmower. The mowers working efficiency was 0.49 hm2/h, and the gas consumption per unit area was 11.41 kg/hm2. |
