In the mechanized sugar beet harvesting process, various functional components achieve efficient harvesting through a collaborative logic of “core execution – pre-auxiliary – subsequent processing,” while performance advantages are deeply adapted to actual field needs through structural design. The detailed specifications are as follows:
As the key unit directly responsible for “detaching beets from soil,” the pulling wheel is not a simple traction structure but an integrated component with dual functions of “gripping” and “preliminary soil removal.” It consists of 3-5 groups of high-strength parallel wheels, with its core lying in wheel surface design: specialized teeth are forged from high-manganese steel and coated with a wear-resistant layer to withstand sand and gravel abrasion; arc-shaped protrusions avoid sharp contact and skin scratches. During operation, the wheel rotation speed is dynamically adjusted based on soil compaction and beet root depth (typically 25-40 cm): reduced to 55-80 r/min for heavy clay soil or deep-rooted beets to enhance traction, and increased to 80-110 r/min for sandy soil or shallow-rooted beets to improve efficiency. As the wheels rotate, the teeth and protrusions penetrate the soil to grip the beet roots, pulling them out smoothly while shaking off surface loose soil (diameter < 2 cm) via centrifugal force, reducing the impurity load for subsequent processing.
To prevent main root breakage caused by forceful pulling, this unit acts as a “soil-loosening assistant” operating ahead of the pulling wheels, installed 10-15 cm in front of them. Powered by a hydraulic motor with stepless power adjustment, it drives wheels equipped with spiral soil-loosening teeth (60° tooth tip angle for easy soil penetration). The loosening depth is adjustable via hydraulic cylinders (18-35 cm), ensuring only circular loosening around the root periphery without touching the main root. This breaks up soil clods, increasing soil looseness around the roots by 40%-60% and significantly reducing extraction resistance—especially suitable for heavy clay soil regions in North and Northeast China.
Integrating “cleaning” and “conveying” functions, this unit addresses the purification and transfer of beets after extraction. The cleaning stage uses a divided approach: grid-type devices intercept soil clods > 4 cm in diameter for field return, while spiral roller devices operate at low speed (15-25 r/min) to strip stems and leaves. The conveying stage employs chain harrow (elastic material to prevent abrasion) and conveyor belt (anti-slip ridges to prevent slipping) devices, stably transferring cleaned beets to subsequent equipment and avoiding secondary handling losses.
Through adjustable parameter design, the harvester adapts to varied planting conditions: adjusting pulling wheel height and speed to match planting densities of 20-30 cm row spacing; modifying excavation unit loosening depth for sandy, heavy clay, and other soil types; even for beets with uneven root thickness or slight lodging, the flexible gripping and conveying design ensures stable operation, unaffected by terrain or crop growth conditions.
Compared to manual harvesting (0.6-1 mu per person per day, 1 mu ≈ 0.0667 hectares), a medium-sized harvester can harvest 1.2-1.8 mu per hour, covering 9.6-14.4 mu in a single workday—15-20 times more efficient than manual labor. This ensures large-area harvesting is completed within the 12-18 day beet harvest window, preventing sugar loss (losing 0.5%-1% per day) or rot from prolonged field retention and safeguarding growers’ profits.
Damage is minimized from the design source: arc-shaped protrusions on pulling wheels and elastic materials in cleaning/conveying prevent skin scratches; pre-loosening reduces extraction force to minimize main root breakage; buffer design in the unloading stage avoids impact damage. The final beet damage rate is controlled within 3%, far lower than the 9%-13% rate of manual harvesting—extending storage life (to 2-3 months) and improving sugar yield in subsequent processing (by 1%-2%).
Product Parameters：
In the actual field operation scenarios of sugar beet fields, this harvesting equipment demonstrates extremely strong operational capabilities — it can easily complete the harvesting task of hundreds of mu of sugar beets in a single day, significantly reducing the time cost under the traditional harvesting mode.
As an efficient piece of equipment for field operations, it also breaks traditional perceptions with its outstanding performance and redefines the industry standards for sugar beet harvesting. Ultimately, this efficient operation mode is directly converted into practical value, bringing significant efficiency improvements to large-scale growers.
