Comparative Analysis of the Snow Clearing Performance Test of the Concave Disc and Vertical Milling Prototype

Abstract

In the north of China, the road is covered with the solid ice-snow which seriously affects the traffic safety of the city, it is a problem that how to clear the solid ice-snow quickly and efficiently. The concave disc clearing machine and the vertical milling clearing machine have been developed respectively based on the thought of agricultural machinery concave disc and vertical milling principle. The concave disc clearing machine is the clearing plate passively cutting ice-snow, which can complete crushing, cutting, scraping, tilt and push five operations. The vertical milling clearing machine is the cutting knife actively cutting ice-snow with function of milling, crushing, copying, obstacle etc, which has a very strong crushing capacity for ice film like high density ice-snow. The comprehensive clearing snow performance test of the concave disc and vertical milling clearing machine were performed under three kinds of road conditions. The test results show that the concave disc machine and the vertical milling machine have good operation, high working efficiency and the clearing rate are all higher than 90%, parameters setting and all indexes can meet the requirements of snow clearing operations. The concave disc machine is suitable for the plate compacted ice-snow which density is lower than 550 kg/m 3 and thickness range from10 mm to 80 mm. The vertical milling machine is suitable for the plate and ice film ice-snow which density range from 300 to 750kg/m 3 and thickness is lower than 50mm, especially suitable for ice film freezing ice -snow, which density is higher than 550kg/m 3 .
