Our company produces spiral clearance machine for soybeans, corn, wheat, barley, rice, rapeseed, sugar beet stems and other cereals clearance, compaction equipment have experienced soybean, rice gravity is bad work under harsh conditions such as tests, from 2000 has accumulated a lot of experience in clearance. By components in the machine layout, spiral blade in the device at the forefront, compaction matter directly with the helical blade contacts, rotating spiral blades easily cut material will be compacted and broken; walking forward a reasonable increase in car weight, overcome the current domestic part there skid clearance machine, climbing and other phenomena; open end of the chute, easier silo wall material into the trough. After years of experience under the constant improvement of the overall structure and details of the device have an absolute advantage, the technical level reached in the same industry-leading level.
