Abstract
The utility model relates to agricultural seeder machinery, belongs to the improvement of mechanical precision hill-drop drill structure, the sowing duckbilled of the mechanical precision hill-drop drill of particularly a kind of improvement.Sowing duckbilled is made up of the movable duckbilled cooperatively interacted and fixing duckbilled, the afterbody of movable duckbilled has symmetrical empennage, its head arranges the U-shaped grooving with cutting blade cutting edge, and feature is: the angle of the groove bottom of movable duckbilled U-shaped grooving and the cell wall shear blade cutting edge of its symmetry is 105 °-115 °, the cell wall shear blade cutting edge of U-shaped grooving symmetry and the angle of U-shaped grooving cell wall outer end cutting blade cutting edge are 65 °-75 °.The utility model is rational in infrastructure, dependable performance, can improve the rupture of membranes rate to improving and thicken mulch film, reduces dislocation rate during sowing, improves the emergence rate of crops seedling.
Description
Technical field
The utility model relates to agricultural seeder machinery, belongs to the improvement of mechanical precision hill-drop drill structure, the sowing duckbilled of the mechanical precision hill-drop drill of particularly a kind of improvement.
Background technology
Current agricultural mulching good Meteorological effect effect has been given birth to great to Chinese Agricultural Production, positive effect, but simultaneously along with the universal residual agricultural mulching of film-mulching technique has also brought a large amount of residual mulching film spoiled soil structure of a series of negative effect, damage to crops normal growth is grown and is caused crop production reduction, and then have influence on agricultural environment, the summary of Research Literature is remained by the relevant mulch film of centering state, to the application present situation of agricultural mulching, the distribution characteristics of residual mulching film and influence factor, and the harmful characteristics of residual mulching film has carried out comprehensive analysis, and for the actual conditions existed at present, propose the prevention technique measure of agricultural mulching residual contamination.The effective prophylactico-therapeutic measures one taked is exactly the quality improving mulch film, improves the mulch film rate of recovery.Existing experimental result shows, if mulch film thick for now widely used 0.006-0.008mm is increased to 0.012mm, and add some anti-aging materials, not only can extend mulch film life-span improve its Meteorological effect effect, and be conducive to clean recovery, but also increase the difficulty of burying to rupture of membranes and the duckbilled of dibbler, and mechanical precision hill-drop drill in the market using dynamicly chews and surely chew structure and mostly be flat mouth, is not just very desirable to the rupture of membranes effect of the mulch film thickened.
Summary of the invention
Handle the sowing duckbilled that the purpose of this utility model is the mechanical precision hill-drop drill providing a kind of improvement, it is rational in infrastructure, dependable performance, can improve the rupture of membranes rate to improving and thicken mulch film, reduces dislocation rate during sowing, improves the emergence rate of crops seedling.
The purpose of this utility model is achieved in that a kind of sowing duckbilled of mechanical precision hill-drop drill of improvement, sowing duckbilled is made up of the movable duckbilled cooperatively interacted and fixing duckbilled, the afterbody of movable duckbilled has symmetrical empennage, its head arranges the U-shaped grooving with cutting blade cutting edge, the angle of the movable groove bottom of duckbilled U-shaped grooving and the cell wall shear blade cutting edge of its symmetry is 105 °-115 °, and the cell wall shear blade cutting edge of U-shaped grooving symmetry and the angle of U-shaped grooving cell wall outer end cutting blade cutting edge are 65 °-75 °.
The utility model increases the groove bottom of movable duckbilled U-shaped grooving and the angle number of degrees of symmetrical cell wall shear blade cutting edge, makes angle be obtuse angle, makes the angle of symmetrical cell wall shear blade cutting edge and U-shaped grooving cell wall outer end cutting blade cutting edge become acute angle.Owing to changing the thorn film angle of movable duckbilled, thus add thorn film time and the thorn film degree of depth, the cutting edge of the oblique point of movable duckbilled matches with fixing duckbilled and is easy to cut brokenly the mulch film thickened, and improves rupture of membranes rate, decreases sowing dislocation rate during sowing.
The utility model is rational in infrastructure, dependable performance, improves the rupture of membranes rate to improving and thicken mulch film, decreases dislocation rate during sowing, significantly improve the emergence rate of crops seedling.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model will be further described, and Fig. 1 is structural representation of the present utility model, and Fig. 2 is the main TV structure schematic diagram of opening one's mouth, and Fig. 3 is the A-A sectional structure schematic diagram of Fig. 2.
Embodiment
A kind of sowing duckbilled of mechanical precision hill-drop drill of improvement, as shown in Figure 1, Figure 2, Figure 3 shows, sowing duckbilled is made up of the movable duckbilled 2 cooperatively interacted and fixing duckbilled 1, the afterbody of movable duckbilled 2 has symmetrical empennage 3, its head arranges the U-shaped grooving 4 with cutting blade cutting edge, and feature is: the angle of the groove bottom of movable duckbilled U-shaped grooving 4 and the cell wall 5 shear blade cutting edge of its symmetry is 105 °-115 °, the cell wall 5 shear blade cutting edge of U-shaped grooving 4 symmetry and the angle of U-shaped grooving cell wall 5 outer end cutting blade cutting edge are 65 °-75 °.
