Abstract
The utility model discloses a novel double spiral type snapping roll which comprises a leading conical section, a snapping section, a strong pulling section and a rear shaft, wherein spiral ribs are welded at the periphery of a cylindrical snapping section base roll; claw-shaped snapping hooks are arranged on the ribs; a spiral auxiliary rib which is parallel to the spiral ribs is welded at the periphery of the cylindrical snapping section base roll; the height of the spiral auxiliary rib is smaller than or equal to the height of each spiral rib. Due to the design of the spiral auxiliary rib, the horizontal distance between the spiral ribs is shortened, the acting strength on a maize stem is enhanced during snapping, the snapping strength is improved, the efficiency is improved, and the drop and damage rate of maize seeds is greatly reduced.
Description
Technical field
The utility model belongs to the corn combine parts, specifically Novel double-helix formula snapping bar.
Background technology
The harvesting parts are core components of maize harvesting machine, and at present, the harvesting modular construction of corn combine has the patterns such as sleeping roll-type, vertical roll type, two groups of roll-types and harvesting plate combined type.Sleeping roll-type ear-picking unit is simple in structure with it, size is less and more be applied on knapsack harvester, and it is comprised of the claw type harvesting hook on harvesting base roller, single-screw formula fin and fin etc.Because the fin of this snapping bar is the single-screw formula, the level interval of spiral ridge is excessive, during work, inadequate to the tension dynamics of corn stem, can cause the defect that harvesting is clean, iblet drops or damage ratio is high, is unfavorable for that corn efficiently gathers in the crops.
Summary of the invention
The technical deficiency that the utility model exists for existing sleeping roll-type snapping bar, provide a kind of reasonable in design, the Novel double-helix formula snapping bar that the harvesting rate is high, corn kernel drops and damage ratio is little.
For achieving the above object, the technical scheme that the utility model is taked is: Novel double-helix formula snapping bar, it comprises front starting taper section, harvesting section, the section of haling and rear axle, be welded with spiral fin on the periphery of cylinder harvesting segment base roller, fin is provided with claw type harvesting hook, it is characterized in that: a spiral auxiliary fin be arranged in parallel with spiral fin of welding on the periphery of cylinder harvesting segment base roller, the height of spiral auxiliary fin is less than or equal to the height of spiral fin.
The beneficial effects of the utility model are: Novel double-helix formula snapping bar, increase the design of spiral auxiliary fin on the periphery of cylinder harvesting segment base roller, the spacing of spiral ridge on snapping bar is dwindled, during harvesting, the dynamics of tension corn stem strengthens, thereby realize that the harvesting rate is high, efficiency is high, and corn kernel fall the purpose that a phenomenon and damage ratio reduce greatly.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. front starting taper section, 2. harvesting section, the 3. section of haling, 4. rear axle, 5. cylinder harvesting segment base roller, 6. spiral fin, 7. claw type harvesting hook, 8. spiral auxiliary fin.
Embodiment
As shown in Figure 1, this Novel double-helix formula snapping bar comprises front starting taper section 1, harvesting section 2, the section of haling 3 and rear axle 4, be welded with spiral fin 6 on the periphery of the base roller 5 of cylinder harvesting section 2, fin 6 is provided with claw type harvesting hook 7, a spiral auxiliary fin 8 parallel with spiral fin 6 of welding on the periphery of the base roller 5 of cylinder harvesting section 2, the height of spiral auxiliary fin 8 is less than or equal to the height of spiral fin 6.
Spiral auxiliary fin 8 adopts fried dough twist steel or other steel bars to make.
Owing to being provided with the spiral auxiliary fin 8 parallel with spiral fin 6 on base roller 5, the spiral ridge total quantity arranged on harvesting section 2 is increased, horizontal range between spiral ridge is dwindled, during harvesting, effect dynamics to corn stem strengthens, the harvesting strength increase, efficiency improves, and corn kernel fall grain and damage ratio reduces greatly.
