黑龙江省嫩江农机厂根据引进原苏联T-7.0型重耙,结合国际先进技术,改装成1BZ-7.0型缺口重耙,很适合收获后整地时间短、土壤粘重的地区使用。该机耙组配置采用双列对置式配置形式,前后两列耙串使土壤移动方向相反,有利于土壤破碎,提高了碎土性能;两侧耙组与中间耙组用铰链联接,由液压油缸驱动,折叠方便,牢固可靠;运输轮起落靠液压油缸驱动,同时装有锁定装置,使之更加牢固可靠,轴承采用向心推力短圆锥滚柱轴承,外加密封壳(轴承座),提高了承载能力,同时延长了使用寿命,并且此种轴承易购、易换,提高
According to the introduction of the former Soviet Union T-7.0 heavy harrow, combined with international advanced technology, converted into a 1BZ-7.0 notch heavy harrow, Nenjiang Agricultural Machinery Plant in Heilongjiang Province is suitable for use in areas with short soil preparation time and soil stickiness after harvesting. This machine rake group configuration uses the double column opposed type configuration form, the front and rear two rows rake string makes the soil move the opposite direction, is advantageous to the soil broken, raises the soil breaking performance; Between both sides rake group and the middle rake group uses the hinged connection, Driven, folding convenient, solid and reliable; transport wheel from the hydraulic cylinder drive up and down, while equipped with locking device to make it more solid and reliable, the use of radial thrust bearings tapered roller bearings, plus sealed shell (bearing), increased load Ability, at the same time extend the service life, and such bearings are easy to buy, easy to change, improve
