Product Introduction
The road mixer is a tractor three-point rear-mounted road construction implement, also named rear-mounted road mixer. This multi-functional mixing machine is the standard subgrade lime soil mixer for stabilizing road base, mainstream rural road construction mixer for village infrastructure upgrading, classic lime soil mixer for mixing soil-lime-cement compound materials, durable hard pavement mixer for crushing old asphalt and concrete roads, and reliable country road paving mixer for low-standard farm passage paving. Equipped with a heavy cast rear bridge and triple reinforced drive chains, it mixes raw soil, lime, cement and broken aggregate evenly in one pass, with customizable working widths ranging from 1.4m to 2m to fit diverse construction environments globally.
Wide Application Fields
Village & Rural Highway Projects
The core usage scenario of this country road paving mixer, including new village road base paving, old country road renovation and farm field access road construction.
Municipal Subgrade Stabilization
Urban branch road, sidewalk, parking lot and factory yard lime-soil base treatment, relying on the subgrade lime soil mixer's uniform mixing performance.
Old Pavement Cold Regeneration
As a heavy-duty hard pavement mixer, it crushes aged concrete and asphalt pavement and mixes waste material on-site for recycled subgrade construction.
Agricultural Land Improvement
Farmland leveling, saline-alkali soil neutralization and hardened farm track foundation mixing with standard lime-soil ratios.
Advanced Standard Production Process
Raw Material Precision Cutting: Thick Q345 manganese steel plates are cut by professional laser equipment to eliminate dimensional errors of cabinet, mixing roller and suspension frame.
Full Deep Penetration Welding: All load-bearing structural joints are fully welded by certified welders to avoid cabinet deformation during long-hour heavy mixing work.
Shot Blasting Anti-Corrosion Treatment: Complete surface rust removal via shot blasting, followed by double anti-rust primer and weather-resistant finish paint to extend outdoor service life.
Hot-Forged Alloy Cutter Manufacturing: Bullet mixing teeth are hot forged with high-hardness alloy steel to resist impact from hard soil and scattered gravel.
Pre-Delivery Full Load Running Test: Every finished rural road construction mixer undergoes a continuous 2-hour high-load test to inspect rear bridge, drive chain and mixing roller stability before export packaging.
Common Customer Fault Solutions
1.Rear-mounted road mixer mixing drum stalls during lime-soil mixing Solution: Immediately cut off tractor power, clear compacted soil and stones jammed between mixing teeth; check the rear bridge gear oil level and refill heavy anti-wear lubricant; adjust chain tensioners to eliminate chain slack.
2.Subgrade lime soil mixer outputs uneven mixing depth on undulating subgrade Solution: Calibrate the tension springs of the front floating scraper to fit ground fluctuations; inspect the tractor hydraulic lifting cylinder for oil leakage and replenish hydraulic fluid in time.
3.Triple drive chain jumps teeth when the rural road construction mixer works continuously Solution: Replace overstretched worn chain segments with standard heavy-duty chains; calibrate chain tension to avoid excessive sagging during high-torque mixing.
4.Alloy cutter tips wear rapidly when the hard pavement mixer crushes broken old roads Solution: Reduce tractor forward speed to lower impact overload; prepare spare alloy cutter assemblies for batch replacement and regularly clear stone debris around the mixing roller.
5.Country road paving mixer rear bridge generates abnormal knocking noise Solution: Drain contaminated old gear oil and inject high-viscosity anti-wear lubricant; disassemble to check for worn differential gears and replace damaged components promptly.
