Abstract
The present invention mainly relates to a no-tillage seeder, particularly to the structure of a cutting knife of an anti-blocking-up device for a no-tillage seeder. The cutting knife of an anti-blocking-up device for a no-tillage seeder comprises an installing hole which is arranged in the center of a knife body. The present invention is mainly characterized in that the present invention also comprises a plurality of knife teeth which are arranged on the external side of the knife body and have the same shape and size, and the knife teeth are composed of a main knife edge, a subsidiary knife edge and a knife back. The present invention has the advantages of reasonable design and reliable usage. The present invention can not only cut off stalks on the ground surface, but also go into the soil and cut off plant roots in the soil to ensure the smooth seeding of the seeder. At the seeding time, a ground seam which is as the width of the knife thickness is cut on the ground surface, and the covering condition of the straws is not damaged. The present invention obtains the effect of coverage, no tillage, seeding, water storage, preservation of soil moisture, and fertilize and soil cultivation of the straws on the genuine significance.
Description
Technical field:
The present invention relates generally to no-tillage seeding machine, relates in particular to the structure of no-tillage seeding machine anti-block apparatus with cutting knife.
Background technology:
In recent years, because stalk no-tillage with straw mulch kind method for planting can be retained and conserved soil moisture, fertilizing soil, energy-conservation saving of labor, obtain popularization more and more widely in China various places.Traditional sower owing to the obstruction of stalk, can't carry out sowing in the stalk mulched ground.In the prior art, application number is 98218325.9, name is called the Chinese utility model patent of " tillage-free mulcher gear tooth-type anti-block apparatus ", discloses a kind of structure of anti-block apparatus, mainly is made up of chaffcutter disk, two tooth-like group grass wheel and ploughs.The cutting knife of technique scheme is the chaffcutter disk, is passive, and the effect of cutting stalk is bad, and anti-blocking performance is very poor.Application number is 98218324.0, name is called the Chinese utility model patent of " the banded anti-block apparatus of pulverizing of no-tillage seeding machine ", a kind of structure of anti-block apparatus is also disclosed, mainly form, do not bury when being characterized in composite blade work by composite blade, plough, ledger-plate, protecting cover and guide plate.The cutting knife of this kind technical scheme is the chopping blade of straw-returning, though the obstruction to stalk has had improvement, but because its operating type carries out on the face of land, can not cut off the root system under the crop field, thereby can not solve the obstruction that root system causes, and power consumption is big, and operating environment is poor, destroy the ground surface that covers, be unfavorable for sowing.
Summary of the invention:
The objective of the invention is to avoid the deficiencies in the prior art part and a kind of no-tillage seeding machine anti-block apparatus cutting knife is provided.
Purpose of the present invention can be by realizing by the following technical solutions: a kind of no-tillage seeding machine anti-block apparatus cutting knife, include at the center of cutter hub (1) and be provided with installing hole (3), the outside of cutter hub (1) is provided with a plurality of shapes, measure-alike cutter tooth (2), cutter tooth by major cutting edge (21), pay blade (22), the knife back (23) is formed.Be characterized in also including at the described helix that is shaped as projection at major cutting edge (21); Paying blade (22) is straight line or curve; The knife back (23) is a straight line; The slip cutting angle a of cutter tooth (2) is that 50-70 °, clearance angle b are 0-15 °, pair blade (22) and the angle c of the knife back (23) is that the central angle of 80-150 °, pair blade (22) is 0-15 °.
Described no-tillage seeding machine anti-block apparatus is embedded on the cutter hub (1) for one or cutter tooth (2) with cutter hub (1) with the cutter tooth (2) of cutting knife.
The no-tillage seeding machine anti-block apparatus is 100～350mm with the crown of the cutter tooth (2) of cutting knife to the centre-to-centre spacing R of cutter hub (1); The thickness of cutter tooth is 1.5-6mm.
Described a plurality of cutter tooth (2) is 2-18, and 3-9 is best.
The material of cutter tooth of the present invention (2) is carbon steel or steel alloy.The cutting edge of cutter tooth (2) is the single face sword or is double-sided blade.
Described cutter tooth (2) can reverse to the face tilt or the cutter tooth of cutter hub.
The invention has the beneficial effects as follows, reasonable in design, use reliably, not only can cut off the stalk of ground surface, and can go deep in the soil, cut off the root system of plant in the soil, sow smoothly to guarantee sower; At seeding time, only ground surface is cut the ground seam of as the thick width of cutter, and does not destroy the situation that stalk covers, reached stalk no-tillage with straw mulch truly sow retain and conserve soil moisture, the effect of fertilizing soil.
Description of drawings:
Fig. 1 looks schematic diagram for the master of the embodiment of the invention 1.
Embodiment:
Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing:
See Fig. 1, no-tillage seeding machine anti-block apparatus cutting knife is provided with installing hole 3 at the center of cutter hub 1, and its outside is provided with a plurality of shapes, measure-alike cutter tooth 2, cutter tooth by major cutting edge 21, pay blade 22, the knife back 23 is formed.Major cutting edge 21 is a spiral of Archimedes, and paying blade 22 is curve, and the knife back 23 is a straight line, and cutter tooth 2 is an one with cutter hub 1.The slip cutting angle a of cutter tooth 2 is that 55-70 °, clearance angle b are 0 °, pair blade 22 and the angle c of the knife back 23 is that the central angle of 80 °, pair blades 22 is 12 °.The crown of cutter tooth 2 is 250mm to the centre-to-centre spacing R of cutter hub 1; The thickness of cutter tooth is 2mm.Cutter tooth 2 is 5.The material of cutter tooth 2 is the 65Mn steel.The cutting edge of cutter tooth 2 is the single face sword.To any one face tilt of cutter hub, cutter tooth does not reverse cutter tooth 2.
