Dual-vibration deep-root crop digging machine

Abstract

The invention belongs to agricultural machinery, in particular relates to a double-vibration deep rooted plant digger which is suitable for digging deep rooted traditional Chinese medicinal materials and roots and stubbles of crops. The digger is formed by the assembly of a traction stander, coulters, a fulcrum shaft of a coulter vibrating grid, a driving motor of a digger shovel, the coulter vibrating grid, a driving motor of the coulters, a governor mechanism for coulter eccentric vibration, a stander, a governor mechanism for depth wheels, a governor mechanism for digger shovel eccentric vibration, depth wheels, a digger shovel vibration hanger rod, a digger shovel, bracket arms of the digger shovel, a tool arm connection plate, a vibration fulcrum shaft of the digger shovel, a coulter vibration eccentric shaft assembly structure and a digger shovel vibration eccentric shaft structure. Double vibration is adopted by the digger to realize the excavation of roots and stubbles; during work, the two driving motors revolve to cause the reciprocating vibration of the digger shovel and the coulters, the coulters at two sides cut the soil, the roots or the stubbles of crops gradually rise from the bottom along a shovel body by the excavation of the digger shovel, and the top of the digger shovel is of coral strip shape to leak the soil and dig the roots or the stubbles from the soil.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a dual-vibration excavator for deep-rooted crops. Background technique [0002] The main rhizomes of deep-rooted Chinese medicinal materials grow longer than the plow bottom, and the deep rhizomes in the hard soil layer under the plow bottom need to be dug out when harvesting. Therefore developing deep-root digging drag-reducing components will become the core and key to realize the deep-root Chinese medicinal material harvesting technology. [0003] Since the 1940s abroad, developed countries such as the United States, West Germany, Japan, France, and Italy have developed a variety of root crop harvesting machines. For example, the mechanized harvesting of long-rooted crops (radish, sugar beet, etc.) and short-rooted crops (potatoes, peanuts, garlic, onions, etc.) has been realized. But the harvest of Chinese herbal medicine crops with a rootstock depth greate...
