Soil loosening knife: a powerful tool for soil loosening and structural improvement
2025-07-30
Type and Structure
Chisel shaped soil loosening knife: made of 45 steel, with high-frequency quenching treatment on the blade, high strength, suitable for deep soil loosening. Its "goose foot style" double wing design can loosen the soil throughout the entire layer, with a V-shaped opening angle of 100 ° and an angle of 30 ° between the front and bottom surfaces, effectively crushing soil blocks.
Rotary tillage knife (seven character knife): Taking the 245 type as an example, the handle width is 3.5 millimeters, and 60 pieces are used in groups to rotate and cut soil. It is suitable for loosening and crushing soil in dry land. Its corrugated blade design can reduce soil cutting resistance and improve operational efficiency.
Installation and adjustment
Depth control: The soil loosening knife is usually installed at the front end of the plow body, and the plowing depth is adjusted through a hydraulic system to meet the needs of different crops.
Angle optimization: The blade bending angle is 150 ° -170 °, balancing soil cutting efficiency and energy consumption, with a tillage width of 130-250 millimeters.
Application scenarios
Stone soil: The chisel shaped loosening knife can loosen and push away the stones, protecting the subsequent plow body from damage.
No tillage seeding: The rotary tiller provides a good seedbed for no tillage seeders through soil crushing and leveling operations, reducing soil compaction.
