Advantage: 1. The design of the front crushing wheel improves the effect of seedling transportation and crushing soil, and the bolt is quickly inserted, and the depth adjustment is more convenient. 2. The excavation shovel is made of high-quality 50 manganese steel, with high-frequency quenching treatment, the shovel tip is wear-resistant and has high impact resistance. 3. The gearbox is safe and reliable and has a long service life 4. The lift chain drive is driven by wear-resistant cast steel sprocket, which has long service life and stable performance. 5. Mainly used for digging and harvesting underground fruits of peanuts, garlic, rhizomes and medicinal crops in clay and semi-sand soils.
Advantage: 1. After the clod is double-clicked on the vibrating wheel, it is pressed again, the soil is cleaned more thoroughly, and the seedlings are transported more neatly. 2. The secondary lift chain separates peanuts and soil more thoroughly. 3. Double-click vibration wheel and elevator chain two-way transmission system, independent of each other, symmetrically distributed on both sides of the machine, improve mechanical balance and ensure more stable operation. 4. The lift chain is sturdy and durable, not easy to bend and deform.
