Abstract
The utility model relates to the technical field of agricultural machinery, in particular to a mechanical device for a no-tillage seeding machine to break stubble, cut up straws and perform ditching operations, and aims at providing a cutter assembly which is simple in structure, high in soil entering capability and capable of breaking the stubble, cutting up the straws and performing the ditching operations. The cutter assembly can cut up the straws and rootstock and loosens the soil on seeding zones, can work normally at high forward velocity, is small in vibration, and improves working conditions. The cutter assembly is simple in structure, convenient in machining and fabrication and low in cost.
Description
Technical field
The utility model relates to a kind of mechanical part that is used for the anti-blocking operation of no-tillage seeding machine, is specifically related to a kind of anti-blocking cutting knife.
Background technology
Protective farming technique is studied early abroad, and in the last few years, along with the enforcement of Ministry of Agriculture's key popularized project, China's protective farming technique had had new progress, has obtained popularization in many areas.At present, Xinjiang region is just being widelyd popularize protective farming technique.Crops such as the blue or green storage of no-tillage seeding corn, oily certain herbaceous plants with big flowers, rape in the ground of a large amount of wheat stalks coverings and the exposed tall and big stubble in the face of land, the development of no-tillage seeding machinery and use are the key problems of promoting protective farming technique.Conservation tillage requires no-tillage seeding machine to have the function of finishing seeding operation at no-tillage stalk mulched ground, and this device that just requires to ditch has broken preferably stubble, hack and penetration performance.In the prior art, Chinese patent CN101828448A, name is called " plough ", though can solve the problem of trench digging, penetration performance is bad; Chinese patent CN1640219A, name be called " no-tillage seeding anti-block apparatus cutting knife " bury and anti-blocking performance good, but broken stubble, trench digging performance are not given prominence to.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, the ability of burying is strong, can finish the mechanical component of breaking, chopping stalk operation, can shred stalk and rhizome.
The utility model technical scheme that achieves the above object is: a kind of no-tillage seeding wedge-shaped indentation cutter assembly, comprise cutter hub, wedge-shaped indentation cutter, copper sheathing, it is characterized in that: cutter hub 1 is as a whole with wedge-shaped indentation cutter 3, and cutter hub 1 is provided with installing hole, and copper sheathing is installed in the installing hole of cutter hub 1.In the peripheral uniform a plurality of sizes of wedge-shaped indentation cutter hub 1, wedge-shaped indentation cutter 4 that shape is identical, the wedge-shaped indentation cutter is made up of blade 40, the knife back 41, wedge-shaped indentation 42.The cutting edge of cutter is circular arc or shaped form, and the knife back is linear pattern or shaped form.Wedge-shaped indentation cutter wedge shape mouth angle is 25 °-75 °.Cutting knife 4 thickness are 5-15mm, and cutter hub 1 boss height is 3-10mm.
The no-tillage seeding wedge-shaped indentation cutter assembly that possesses above feature has the following advantages: wedge-shaped indentation cutter 4 is as a whole with cutter hub 1 in (1) this no-tillage seeding wedge-shaped indentation cutter assembly; (2) blade 40 of the cutting knife of this no-tillage seeding wedge-shaped indentation cutter assembly is a camber line shape, can produce sliding cutting to stalk and root system, prevents obstruction, and through performance is better.
The wedge-shaped indentation cutter assembly that the utility model provides can operation under higher operating rate, vibrates lessly, has improved condition of work.
Description of drawings
Fig. 1 is main TV structure figure of the present utility model.
Diagram 1 is the wedge-shaped indentation blade, and 2 is locating hole, and 3 is copper sheathing, and 4 is the wedge-shaped indentation cutter, and the wedge-shaped indentation cutter is made up of blade (40), the knife back (41), wedge-shaped indentation (42).
Fig. 2 is that the axle that waits of Fig. 1 is surveyed view.
Diagram 1 is the wedge-shaped indentation blade, and 2 is locating hole, and 3 is copper sheathing, and 4 is the wedge-shaped indentation cutter.
Embodiment
With reference to accompanying drawing, wedge-shaped indentation cutter 1, cutter shaft 2, copper sheathing 4.Copper sheathing 4 is fixed in the square opening on the wedge-shaped indentation blade 1, and wedge-shaped indentation knife assembly 1 is by the cutter shaft connection of copper sheathing 3 with no-tillage seeding machine.During operation, no-tillage seeding machine is by tractor-drawn, and self part gravity of no-tillage seeding machine is applied on the cutter shaft, pass to the wedge-shaped indentation knife assembly by cutter shaft, the wedge-shaped indentation cutter of rotation cuts off stalk, root stubble, shred, and the soil of the face of land 8-15cm soil layer that ravels is left groove and finished sowing.The utility model is applicable to no-tillage seeding machines such as oily certain herbaceous plants with big flowers, rape, corn.
The utility model is provided with wedge-shaped indentation on edge, can increase the disconnected stubble of cutter, the ability of being completely cured, and can reduce the soil that blade is stained with simultaneously, influences operating efficiency.
Advantages such as in sum, the utility model is to have the disconnected stubble of no-tillage seeding of choke preventing function, the device of being completely cured, and it is strong to have the ability of burying, and anti-blocking ability is good, and simple in structure, use is flexible.
