Abstract
The utility model mainly relates to a no-tillage seeder, in particular to a blade stubble-cutting furrow opener of a no-tillage seeder and belongs to the field of agricultural seeding machines. The blade stubble-cutting furrow opener comprises a main knife body (1), a reinforcing rib (2), a countersunk head rivet (3), a left wing knife (4) and a right wing knife (5), wherein the left wing knife and the right wing knife are fixed on the main knife body by the countersunk head rivet; the main knife body slips straw and weed to the rear part; the wing knives cut the root systems of proceeding crop; and the cut crop are split and flow toward both sides of the furrow opener, so that the aims of loosening the soil and providing a good seedbed environment are achieved by the main knife body and the wing knives. By using the reinforcing rib, the strength of the blade stubble-cutting furrow opener is improved, and the service life is prolonged. The blade stubble-cutting furrow opener can complete stubble-cutting and furrow-opening operation and has the advantages of high stubble-cutting and furrow-opening effects, high universality, a small amount of upset soil, low power consumption, simple structure and the like. By the blade stubble-cutting furrow opener, the agronomic requirements on no-tillage seeding can be met.
Description
Technical field
The utility model relates generally to no-tillage seeding machine, relates in particular to the breaking trench digging device in the no-tillage seeding machine, belongs to agricultural seeder machinery field.
Background technology
Protective farming technique comes from the U.S., be the thirties in 20th century U.S. after attacked by " black burn ", people have recognized that the main cause that causes sandstorm is is main tillage method with the mouldboard plow.Summed up afterwards no-tillage, minimal till the conservation tillage method at the center that is covered as with stalk, thereby realized agriculture sustainable development.One of key technology of conservation tillage is exactly the no-tillage seeding technology; Supporting with it crucial facility are no-tillage seeding machines; It adopts no-tillage; Minimal till and method that stalk covers, operations such as collection breaking, fertilising, sowing, earthing are one, can play the remarkable result of preserving the ecological environment, improve soil structure, cost-saving synergistic.
The workpiece of no-tillage seeding machine is except that the requirement of satisfying general sower; Special breaking parts also should be installed, should have the trench digging of breaking preferably ability, can cut off the stalk of upper soll layer stubble and crop; Cut hard soil layer, for seed sprouting is created good condition.At present, breaking parts commonly used mainly contain shovel formula, disc type and driving type rotary blade.Shovel formula breaking parts are bigger to soil disturbance property, and are prone to twine stalk, weeds, stop up; Disc type breaking parts embedded depth is shallow, needs to rely on sower own wt or counterweight to increase embedded depth; Driving type rotary blade consumed power is big, complex structure and bigger to soil structure destruction, can't reach the requirement of conservation tillage.In order to overcome the problem that existing breaking parts exist, the utility model provides a kind of novel corn rootstalk cutting device.
Summary of the invention
The utility model provides a kind of novel corn rootstalk cutting device one blade breaking plough, can accomplish breaking, ditching operation.This device has that breaking trench digging is effective, highly versatile, the amount of breaking ground is little, consumption of power is few, advantages of simple structure and simple.
The utility model technical scheme is achieved in that a kind of blade breaking plough, comprises operator body 1, reinforcement 2, sunk head rivet 3, left wing's cutter 4, right flank cutter 5, and material all adopts 65Mn.Operator body 1 is characterized in that the top is rectangle, is convenient to blade breaking plough and is fixed on no-tillage seeding machine front-axle beam (can regulate embedded depth according to the height of rectangular surfaces) through fixed head and " U " type set bolt; The below is cambered surface and cutting edge is arranged, and help stalk, weeds to slide to blade breaking plough rear along cambered surface, but cutting edge also cut-off parts stalk, weeds divides to both sides stalk and weeds, assurance no-tillage seeding machine operate as normal.Blade breaking plough both sides are equipped with left wing's cutter 4 and are fixed on the operator body 1 through sunk head rivet 3 with right flank cutter 5 (the wearing and tearing back is replaceable); Be shaped as isosceles right triangle; And have cutting edge; Left wing's cutter 4 and right flank cutter 5 be at same horizontal plane, vertical range 50mm overhead, and the horizontal range of two wing fence outermost end is 50mm; Penetrating angle is 5 °, buries about 5cm, is convenient to sliding cutting preceding crop root system, and it is shunted to both sides, and good kind bed is provided.Reinforcement 2 is fixed on operator place, body 1 rear side right angle, helps improving the intensity of blade breaking plough, increases service life.

Fig. 2 is the right view of the utility model.
Diagram 1 is the operator body, and 2 is reinforcement, and 3 is sunk head rivet, and 4 is left wing's cutter, and 5 is the right flank cutter.B is the trench digging width.
Embodiment
The utility model embodiment is referring to accompanying drawing 1, accompanying drawing 2, a kind of blade breaking plough, and mainly by operator body 1, reinforcement 2, sunk head rivet 3, left wing's cutter 4, right flank cutter 5 is formed.Blade breaking plough is fixed on the no-tillage seeding machine front-axle beam through fixed head and " U " shape set bolt, moves ahead with locomotive, and blade breaking plough buries about 10cm, at the operator body 1 5cm place of burying; Left wing's cutter 4 is equipped with in its both sides, right flank cutter 5, and through sunk head rivet 3 be installed in the operator body 1 on; And the wearing and tearing back is replaceable, left wing's cutter 4, right flank cutter 5 sliding cutting weeds root systems; Weeds are shunted to both sides do not heap,, constantly move ahead with locomotive even if there are a spot of weeds to hang over cutter hub; Weeds slide onto the top by operator body 1, turn over then to fall, and remain steady state.
It should be noted last that; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
