1WS-120 High-Efficiency Agricultural Rock Picker & Stone Collector

Core Technical Highlights

• Precision Hydraulic Control: Equipped with a full hydraulic system for both depth adjustment and hopper discharge. With a working depth of up to 150mm, operators can easily manage soil penetration from the tractor cabin.

• Advanced Separation Technology: Utilizing a scientific conveyor-chain mechanism, the machine separates stones from soil with high precision. It handles stones ranging from 5cm to 20cm in diameter, ensuring clean soil is returned to the field immediately.

• High-Clearance Self-Discharging: Features a 0.5m³ collection hopper with a tipping height of 2.3 meters. This allows for direct unloading into trailers or dump trucks, streamlining the waste removal process.

• Superior Durability: The separation tines are manufactured using advanced international forging processes and wear-resistant alloy steel, ensuring long-lasting performance even in the most abrasive and stony terrains.

Why Choose the 1WS-120?

1. Machinery Protection: Eliminate rocks that damage expensive rototillers, seeders, and harvesters, significantly reducing your fleet's maintenance costs.

2. Increased Crop Yield: Ideal for potato, carrot, and sugar beet farming, where stone-free soil is essential for uniform tuber development and high marketable yields.

3. Versatile Application: From land reclamation projects to maintaining construction sites or prepping orchards, this machine is a versatile asset for any large-scale land management operation.

Part 1: Key Application Scenarios

1. Pre-planting Preparation for High-Value Root Crops

Before planting crops such as potatoes, garlic, carrots, and sugar beets, stones in the soil can cause tuber deformation, skin damage, or mechanical jamming during harvest. The 1WS-120 ensures a stone-free seedbed, guaranteeing premium crop appearance and meeting high export standards for organic and industrial farms.

2. Land Reclamation & Soil Remediation

Ideal for transforming virgin land, rocky hillsides, or former construction sites into arable farmland. This machine efficiently clears debris and rocks, improving soil aeration, water retention, and overall tilth, making it a vital tool for large-scale land development projects.

3. Protective "Scout" for Expensive Machinery

Use the rock picker as a primary pass before deploying high-precision seeders or expensive combine harvesters. By removing rocks that are "machinery killers" for blades and gears, the 1WS-120 reduces downstream equipment failure rates by over 50%, significantly extending the lifespan of your entire fleet.

Frequently Asked Questions (FAQ)

Q1: What are the tractor requirements for the 1WS-120?

A: It is a trailed machine requiring a tractor with 70 HP or above. Your tractor must be equipped with a standard PTO output and two sets of hydraulic remote valves to drive the conveyor chain and control the hopper discharge.

Q2: What is the minimum and maximum stone size it can collect?

A: The machine is optimized for stones ranging from 5cm to 20cm (2" to 8") in diameter. Smaller pebbles pass through the screen to maintain soil structure, while boulders larger than 20cm should be pre-treated with a front-end loader.

Q3: How does it perform in wet soil conditions?

A: For the best soil-stone separation, we recommend operating when soil moisture is below 20%. Excessively sticky or wet mud can clog the separation screen; the efficiency is highest in dry or slightly moist soil.

Q4: What is the ideal operating speed?

A: To allow sufficient time for the soil to sift through the chain while moving stones into the hopper, we recommend a working speed of 1–3 km/h (0.6–1.8 mph).

Q5: How do I unload the stones once the hopper is full?

A: The 1WS-120 features a high-clearance hydraulic tipping system. With an unloading height of 2.3 meters, you can drive alongside a trailer or dump truck and discharge the stones directly using the tractor’s hydraulic controls.
