Description
Technical field
The present invention relates to agricultural machinery technological field, specially a kind of Radix Astragali digger blade with bionic curved surface structure.
Background technology
The Radix Astragali is perennial legume, and medicinal and edibility concentrates on main root part, belongs to large rhizome traditional Chinese medicinal materials
One of.Radix Astragali root growth is deeper, and soil is goed deep into up to 500-1000mm in root, and harvest has that excavating resistance is big, rhizome is damaged
Hinder the problems such as rate high, digging element and serious soil adhesion, rely primarily at present it is a large amount of manually adopt plane main root, labor intensity is big,
Excavating cost is high, efficiency of crop is low.The isometric tubers of the Radix Astragali is harvested from the tubers such as existing potato, sweet potato harvesting equipment
During crop, the problem of excavating resistance is big, soil adhesion amount is high is there is, it is impossible to reach basic use requirement.The Radix Astragali harvests recruitment
Amount accounts for the Radix Astragali entirely produces overall process more than 1/3, and operating cost accounts for more than the 50% of total cost of production.
Research finds that soil animal tatou forms distinctive body surface morphosis by long-term evolution, forms spy
There is claw type structure, have the ability that can adapt to living environment.The four limbs of tatou are very sturdy, and the pawl on toe is sharp and strong
Firmly, very effectively, can dig a hole existence on hard soil.Tatou pawl toe does not adhere to soil in excavation soil course median claw toe,
Excavating resistance is small, and digging efficiency is high.Tatou head talent arch soil in pawl toe excavates soil course, coordinates burrowing behavior, head body surface
Bulge-structure with hexagon, assistance reduces adhesion of the soil to pawl toe, reduce further soil excavating resistance.
The content of the invention
The present invention has that labor intensity is big, excavating cost is high, rhizome damage ratio high, adhesion to solve existing Radix Astragali harvest
There is provided a kind of Radix Astragali digger blade with bionic curved surface structure for the problem of serious and efficiency of crop is low.
The present invention adopts the following technical scheme that realization：A kind of Radix Astragali digger blade with bionic curved surface structure, including
Spade, shovel body and spear that tail head is sequentially connected；The tatou pawl toe shape that shovel body is made up of upper tactile native curved surface and lower tactile native curved surface
Structure, spear includes main spear and the side spear positioned at its left and right sides.
In operation process, Radix Astragali digger blade is fixed on tractor mounnted frame, as tractor carries out cutting native digger
Make, the main spear of digger blade is located at foremost, take the lead in being pierced into soil, secondary spear is pierced into soil with main spear, and three spears are formed
Multiple spot is pierced into state, and reduction soil is pierced into resistance, and spear gap constitutes side edge, gradually switches off Radix Astragali rhizome, reduces the Radix Astragali and excavates
The direct impact to rhizome is shoveled, the harvest damage of reduction Radix Astragali rhizome excavates shovel body cutting soil and excavates the Radix Astragali, upper tactile native curved surface
With bionic geometric structure, reduce adhesion of the soil to shovel body, reduce the soil adhesion resistance of digger blade；Tatou pawl toe is hard
Soil property in broken ground, cut soil and remain that shovel body form does not change during dragging soil, its excellent performance is in it
The digger blade of his type, solves other types digger blade and is not suitable for excavating hard soil property or the deeper reality of excavating depth well
Border problem, it is ensured that efficiency of crop height, consuming little energy during autonomous harvesting, digging element are hardly damaged.Overcome existing
With the presence of Radix Astragali harvest labor intensity is big, excavating cost is high, rhizome damage ratio high, adhere to the problem of serious and efficiency of crop is low.
