Description
Technical field
The present invention relates to a kind of bionical digger blades of knob tubers, belong to agricultural machinery technological field.
Background technique
Root crop occupies very big specific gravity in China, with constantly improve for tubers industrial crops market, rhizome
Class crop demand is increasing, however the root crop of knob is grown in special red clay mostly and is not easy to dig
Pick, in addition rhizome is more dispersed, during the harvest of root crop, the superiority and inferiority of digger blade directly affects the complete of mechanical work
Cheng Xingneng and efficiency of crop.China has a vast territory, and the soil property and plantation agronomy in each producing region have very big otherness, external
The harvest machine of research and development cannot meet the harvest requirement of China's most area, and therefore, it is difficult to be promoted and used.Other
Stem class cropper does not adapt to the requirement of knob tubers production, exists obviously not especially in reliability and adaptability
Foot.Labor intensity is big, spends the time too long, and cost of labor is too high, causes economic loss, restricts rhizome traditional Chinese medicinal materials industry
Development.
Three seventh is that traditional rare traditional Chinese medicine, the special effect with activating microcirculation and removing stasis medicinal, detumescence ding-tong, usage history nearly one thousand years, are enjoyed
The good reputations such as " invaluable ", " southern part of the country god grass ", " king in ginseng ".Yunnan Province is the maximum Radix Notoginseng production base in the whole nation, is also simultaneously
The fourth-largest potato production base in the whole nation, root crop Mechanization Level is very low, existing tubers digger blade form list
One, the mostly divided shovel of plane shovel, concave surface shovel, groove type shovel and minority, cannot efficiently solve resistance in mining process
Greatly, the problem of clay is serious, sandstone is worn, energy consumption is high.And existing digger blade cross section be mostly it is close trapezoidal, when operation, soil
Big with the contact area of digger blade, the adhesive capacity of soil is also big, so that digger blade working resistance increases, energy consumption is high, breaks ground, hack
Ability is poor, and potato-damaging rate is higher, and shovel face wearability is bad.The connection type of digger blade and rack is mostly welding, when digger blade exists
When being damaged in the course of work, it is not easy to dismantle and repairs, digger blade can only be replaced in most cases, cause waste of material.Therefore
The present invention effectively to solve that resistance in tubers mining process is big, energy by designing a kind of curved surface shovel, waveform transition section
The problems such as high, the de- soil nature of consumption can be poor, improves the efficiency of tubers mechanized harvest.
