Overview
The 12JS series is HONGYOU's heavy-duty trailed stone picker line, available in 130, 160 and 190 working widths to match 130 – 200 HP tractors. A backhoe-style stabilizer digs to 300 mm, a grid-chain conveyor lifts soil and stones to a hob-sorting separation unit, and cleaned stones drop into a 3 – 4.2 m³ centralized collection box. The box raises hydraulically to 2000 mm unload height for direct dumping into trailers.
Key features
Backhoe stabilizer digging
Stable excavation device adjustable from 0 – 300 mm, designed for hard rocky soil.
Hob sorting separation
Roller-hob sorting system cleans stones more aggressively than vibration-only screens.
Grid chain conveyor
45# carbon steel bars with dual 50.8 / 63.5 mm gap options for different stone sizes.
Large centralized collection box
3 – 4.2 m³ box capacity reduces unloading cycles in heavy stone fields.
Hydraulic high-lift unloading
Hydraulic cylinder lifts the box to 2000 mm — direct dumping into trucks or trailers.
