2MB-2/4型夏花生灭茬覆膜播种联合作业机的研究

Study on 2MB- 2 /4 Type of Summer Peanut Stubble Mulching Planting Combined Machine

目前,中国夏花生播种存在作业效率低、劳动强度大及生产成本高等突出问题[1]。为解决此类问题,研制了一种2MB-2/4型夏花生灭茬覆膜播种联合作业机。该机主要由旋耕装置、起垄装置、驱动装置、施肥装置、播种装置、镇压装置、喷洒装置及覆膜装置等组成,可一次完成花生种植的灭茬、起垄、施肥、播种、镇压、喷药及覆膜等作业,可减少人工投入。田间试验表明:该机作业性能良好,根茬粉碎率77.3%,碎土质量74.5%,垄间合格率89.1%,垄高合格率93.4%,双粒率95.04%,穴距偏差率6.8%,种子覆土深度合格率89.2%,均符合花生播种机行业标准DG/T 007-2006《播种机推广鉴定大纲》要求,满足实际生产需要。

At present China summer peanut seeding has low work efficiency,large labor intensity,high production cost and outstanding problems[1]. In order to solve this problem,this paper has developed a 2MB- 2 /4 type of summer peanut stubble mulching planting combined machine. It mainly consists of rotary device,ridging device,driving device,fertilizer device,seeding device,pressing device,spraying device,coating device and other components. It can be a complete peanut planting of stubble cultivator,ridging,fertilization,planting,repression,spraying,coating and other operations,reducing manual input. Field test shows that: the machine operating performance is good,with stubble crushing rate 77. 3%,broken soil quality 74. 5% pass rate of 89. 1%,the ridges,ridge high pass rate of 93. 4%,the double grain rate 95. 04%,hole deviation rate 6. 8%,seed depth pass rate of 89. 2%,all in line with the peanut planter industry standard DG / T 007- 2006 'seeder to promote the identification program'requirements,meet the needs of production.
