我国北方城市传统的除雪理念是雪停后除雪,这种除雪方式主要是清除压实雪。压实雪除雪机械设计技术难度较大,设备制造成本较高,除净率低,工作效率低,难以大量推广应用。阐述了城市道路机械化“实时除雪”的全新理念。机械化“实时除雪”方式是以清除散雪为主,使用散雪除雪机械在降雪过程中边下雪边清除,雪停后除雪工作基本完成。基于这一理念开展研究工作并开发出JD-SX2800、JD-SX3500型散雪除雪机。除雪机采用小型农用自卸汽车做为配套动力,结构简单,制造成本低廉。对上述除雪机的设计思想、结构设计、液压控制系统设计、配套动力选择及技术性能指标等作了介绍。两种机型的除雪厚度为0～400mm,行走速度8～25km/h,除雪装置质量270～320kg。
The traditional concept of snow removal in the northern cities of our country is the snow removal after the snow is stopped. The main method of removing snow is to remove the compacted snow. Compaction snow snow removal machinery design technology more difficult, higher equipment manufacturing costs, in addition to low net rate, low efficiency, it is difficult to promote a large number of applications. Elaborated the city road mechanization “real-time snow removal” the new idea. The mechanized “real-time snow removal” method is mainly for removing loose snow, and the use of snow-removing snow-removing machinery removes the snow while snowing, and the snow removal after the snowfall is basically completed. Based on this concept to carry out research and development of the JD-SX2800, JD-SX3500-type snow snow blower. Snow plow small agricultural dump truck as a supporting power, simple structure, low manufacturing costs. The design concept, structure design, hydraulic control system design, supporting power selection and technical performance index of the above snow blower are introduced. Snow removal thickness of the two models is 0 ~ 400mm, walking speed 8 ~ 25km / h, snow removal device quality 270 ~ 320kg.
