Product Introduction
The 1.8-meter box type lime soil mixer is a tractor rear-mounted road construction attachment designed for mixing lime, cement, gravel and raw soil to form stable subgrade layers. It is recognized as a reliable box-type soil stabilizer mixer for rural highway reconstruction and low-grade municipal road paving projects. Also named box-type stabilized soil mixer, this heavy-duty mixing unit blends raw soil with solid curing agents evenly in one pass, eliminating manual layered mixing and cutting construction cycles. As a professional rural road mixer, it fits small and medium tractors widely used in countryside infrastructure. Classified as a functional subgrade soil mixer and road base mixer, it counts as core engineering road mixing equipment for subgrade reinforcement, and acts as a dedicated subgrade soil stabilizer to guarantee uniform compaction performance of road foundation layers. Its 1.8m full working width delivers high linear efficiency for continuous road base construction.

Material & Structural Construction
Thickened Sealed Box Body: Main mixing cabinet adopts thick Q345 manganese steel plate, processed by laser cutting and full penetration welding to resist impact from stone and soil mixture, avoiding deformation under long-hour heavy mixing loads.
Heavy-Duty Mixing Drum & Blades: 245mm diameter solid mixing roller matched with integrated bullet alloy blades; each blade is individually bolt-mounted for separate replacement, lowering long-term maintenance expense.
Reinforced Drive Gearbox & Chain: Central cast steel gearbox transfers stable power, paired with thickened heavy-duty drive chains that resist stretching under high-torque mixing work.
Spring Adjustable Scraper Board: Front floating scraper plate with buffer springs automatically fits uneven ground, preventing material leakage during mixing and ensuring consistent subgrade mixing thickness.
Standard Three-Point Suspension Bracket: Thick triangular welded hanger fits most common medium and large tractors for quick mounting and disassembly.
Comprehensive After-Sales Support for Global Buyers
1.12-month factory warranty covers core gearbox, mixing drum and drive chain assembly under standard construction operating conditions.
2.Professional multilingual technical team offers 24/7 online video guidance for tractor matching, installation, operation and routine maintenance.
3.Fast global spare parts supply chain: alloy bullet blades, drive chains and gearbox seals can be delivered within 7 working days after bulk order confirmation.
4.Customized size modification service: We produce 1.4m, 1.6m, 2.0m width models to match different road width requirements, supplying free technical drawings for full-container wholesale clients.
Practical Common Fault Solutions
1.Box-type stabilized soil mixer mixing drum stalls when mixing soil-lime mixture Solution: Stop tractor power supply, clear large stones and compacted soil stuck between mixing blades; inspect drive chain tension and tighten loose adjusters; replenish heavy-duty lubricant into the central gearbox.
2.Uneven mixing depth on undulating road surface Solution: Adjust the tension springs of front floating scraper plate to fit ground fluctuation; check tractor suspension lifting hydraulic cylinder for oil leakage and refill hydraulic fluid timely.
3.Drive chain slips and jumps teeth during continuous mixing Solution: Remove worn chain links and replace with new standard 24A heavy-duty chains; adjust chain tension to eliminate excessive sagging caused by long-hour operation.
4.Alloy bullet blades wear rapidly when mixing gravel-containing subgrade soil Solution: Reduce tractor forward travel speed to avoid overload impact; stock spare blade assemblies for batch replacement, regularly clear stone debris around mixing roller to reduce blade abrasion.
