Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of cutter not isometrical angle mount formula stubble-cleaning is provided to remove obstacles ditching device, this device cutter is by coiling different-diameter two groups of holes circumferentially and be connected with connecing, carry out angle mount, make cutter outer face relatively and ground shape have a certain degree, reduce invalid resistance and tool wear, reduce power consumption, even if the oblique sword rectangular cutter installed out still can have sawing motion to stalk, cutter hub is wide and not stupid, cutter life is long, simultaneously stubble-cleaning is removed obstacles trench digging, convenient sowing, without the need to farming, stalk is also field on earth's surface, do not press seedling.

The utility model comprises cutter shaft, gearbox, bearing block, stationary knife, case, it is characterized in that: described cutter shaft comprise clearly stubble ditching knife, mandrel, connect dish, connecing dish is connected on mandrel, described clear stubble ditching knife profile is trapezoidal or rectangle bending structure, there are two connecting holes, enclose connecting hole be connected with the circumference at the connecting hole place, outer ring connect on dish, circumferentially inside and outside two of the inner ring connecting hole place connect on dish, form angle mount formula, clear stubble ditching knife outer face is at a certain angle relative to shape between the tangent to periphery of point of a knife place.

Described mandrel also connects short stubble-cleaning knife, is responsible for the stubble-cleaning work on wide ridge, need not ditches.

Described case sets cutter, to improve stalk crushing effect, prevents long stalk from throwing away.

Technique scheme is known, the utility model can be provided on Novel straw returning no-tillage seeding fertilization spray medicine all-in-one, clear stubble ditching knife end is wider, or even rectangle, good rigidly, bilateral commutative use, tool life improves greatly, a seeding and fertilizing spray medicine all-in-one generally fills 72 ~ 96 clear stubble ditching knife, within 1 year, can save cutter accessory and take thousands of unit.This device can will be sprinkling upon the earth's surface in the ranks of sowing after stalk fragmentation, and with a small amount of earth pack, prevents wind, burning, is conducive to keeping soil moisture, facilitates stalk absorbed nitrogen element degraded also field from air; At sowing ridge place, clear stubble is ditched, convenient sowing, and realizes no-tillage, reduces the plough end phenomenon, particularly autumn and is conducive to the solid roots in easy lodging crops etc. such as corn; Without being wound around, without congested, stalk is also field and do not press seedling from earth's surface, can not form high pin seedling, the favourable soil moisture conservation in improving straw mulching earth's surface, suppression weed growth etc.; Grain-production is more got close to nature, realizes production estimation benign cycle.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, the utility model comprises stubble ditching knife 1 clearly, mandrel 3, connects the cutter shaft that dish 2 etc. formed, then connects gearbox, bearing block, in conjunction with compositions such as stationary knife 5, cases 6.

Wherein, clear stubble ditching knife 1 has stubble-cleaning to remove obstacles the function of trench digging, except ensureing the straw-returning of place of arrival, can prevent from being again wound around, and outputs the soft groove of certain depth, convenient sowing for sowing.Shown in composition graphs 2, the basic profile of clear stubble ditching knife 1 is trapezoidal or rectangle bending structure, and end is wider, has two connecting holes.Connect on dish 2 and be drilled with inside and outside two circle connecting holes, form the circumference 21 at connecting hole place, outer ring, the circumference 22 at the inner ring connecting hole place connect on dish that connect on dish.Two holes of clear stubble ditching knife 1 respectively with connect inside and outside circle connecting hole on dish 2 and be connected, form angle mount formula, certain angle β is lifted relative between point of a knife place tangent to periphery (being equivalent to the bottom of trench of soil trench digging) in so clear stubble ditching knife 1 outer face, end face can be avoided to contact with bottom of trench and to cause invalid resistance, produce power consumption and tool wear.The blade of clear stubble ditching knife 1 forms the circumference 11 at stubble ditching knife point of a knife place clearly, blade and excessively point of a knife have certain angle η to the line meeting disk center, clear stubble ditching knife 1 has certain sawing effect (sawing is not impact cutting) to stalk in the motion that cutter shaft rotates and main frame advances, the stalk that more convenient cut-out toughness is higher, and this clear stubble ditching knife 1 due to outer end wider, relatively pointed cutter rigidity is better, not yielding by greater impact, another side can also be changed after uneven wear and continue to use.
