Autonomous Sunflower Breeder Thresher: A Mobile Tool for Precision Seed Production

A new era of in-field post-harvest processing for researchers and growers running large-scale breeding programs

1. Why Breeders Need a Dedicated “Sunflower Combine”

• Small plots, many hybrids. Each hybrid line must be threshed separately to prevent genetic mixing.
• Tight time window. Sunflower heads dry rapidly after cutting, raising the risk of shatter losses.
• Field-side realities. Many breeding sites lack power lines or access for full-size machinery.

A compact autonomous thresher solves all three: drive it straight to the plot and process heads on the spot .

2. Design and Workflow

A single pass < 15 s, up to 1 kg of clean seed; throughput ≈ 200–300 kg/h for breeding work.

3. Full Autonomy and Mobility

Internal-combustion engine powers drum, fan and conveyor — no tractor or grid required.

Lightweight frame bolts to a standard passenger-car trailer; any pickup or van can haul it.

Curb weight < 550 kg fits within typical category-B trailer limits.

Ten-minute setup: all fold-outs lock with cam levers, no tools needed.

Kazakh case study. The customer shuttles the unit between 2–3 ha trial plots, cutting turnaround time by up to 40 % versus trucking heads back to a base station.

4. Lab-Grade Safety in the Field

• Enclosed drum housing with safety interlocks: lid lift stops the rotor instantly.
• Rubber dampers isolate engine vibrations—less dust, better operator comfort.
• RAL 3005 powder coat (90 µm) over zinc primer resists corrosion from Kazakh steppes to southern Ukraine.

5. Compact Engineering, Big Potential

The autonomous thresher brings precision seed work from warehouse-scale plants to mobile field workshops. Trailer mobility, off-grid power and fine adjustability make it ideal for:

• public and private breeding centres;
• agricultural research institutes;
• farmer-breeders running their own hybrid trials.

Handling hundreds of hybrid lines each season? This machine minimises costly seed losses, speeds selections and removes grid-power constraints—turning the field itself into your processing lab.
