摘要
我国北方地区冬季雪灾较严重,为了解决大雪压塌大棚问题,设计一种新型大棚除雪机,并对其除雪机构、输送机构及功率消耗进行理论计算和试验验证。研究表明,采用硬质毛刷和螺旋机构制成的除雪机,适合清扫屋面的较厚积雪,减小除雪过程中的阻力,降低农民的劳动强度。理论分析和样机试验较吻合。试验表明,整机结构合理,具有很好的除雪效果,达到预期设计目标。
Snow in winter in northern China is of the snow collapsing the greenhouse roof, this more serious disaster, in order to solve the problem paper designed a new of king greenhouse snow blower, and conducting theoretical calculation and experimental verification on the snow blower mechanism, convey mechanism and power consumption. The research showed that the snow blower with hard brush and screw mechanism was appropriate for cleaning thicker snow, reducing the the resistance of snow blower process, and reducing the labor intensity of the farmers. The theoretical analysis and the prototype test was identical. Tests showed that the structure of snow blower wais reasonable, and had good effect, achieving the anticipated design goal.
