One face of the base is provided with a lug plate connected with a working arm of a digging machine, a connecting shaft hole is formed in the lug plate, the other face of the base is provided with two parallel plate type hooked knife handles, the ends of the hooked knife handles are provided with tree root splitting knives, tree root cutting knives are arranged along the inner arc edges of the hooked knife handles, a tree root pulling-out knife is arranged between the two hooked knife handles and is fixed perpendicular to the plate faces of the two hooked knife handles, and the knife edge of the tree root pulling-out knife points to the tree root cutting knife side. The tree root digging knife can split large-diameter tree root stubs into pieces to be pulled out one by one and cut longer root hairs into small sections to be dug out, and is applicable to pulling out tree roots with various diameters, high in working efficiency and good in pulling-out effect.
Description
Technical field
The utility model relates to a kind of digging tool, especially a kind of be arranged on working arm of excavating machine end use, for tree root is excavated to device out from soil.
Background technology
Trees are felled rear tree root and can remain in soil, affect the development and utilization again in soil, therefore, after tree root need to being excavated from soil out, could soil be carried out smooth and be utilized, in prior art, not be specifically designed to the instrument that excavates tree root, adopt excavator bucket to carry out digging operation more, bucket is limit by structure to be deeply inserted in soil, can only be by tree root soil around to be excavated, recycling bucket is removed down tree root, pull out, and operating efficiency is lower.CN 203399571 U disclose a kind of machinery and have dug tree root pawl, this machinery digs tree root pawl and comprises 2 semicircle hooks, one end of described semicircle hook connects drive division, semicircle hook becomes sickle shaped with drive division, drive division has driving shaft installing hole, a plate connects 2 drive divisions to make 2 semicircle hooks side by side, the other end of semicircle hook has tip, this tree root pawl that digs coordinates common excavator to use, when use, be installed on the cantilever end of common excavator by driving shaft installing hole, utilize the vibration of excavator cantilever end that bill portion is inserted to a tree root and blocks, tree head is connected to the root ground of extricating oneself from a predicament and brace oneself up to action.But, because digging tree root pawl, can not cut tree root by this machinery, tree root entirety can only be pulled out, and its working resistance is larger, in the time running into the larger tree root in coring prosperity or root footpath, just there will be and pulls out difficulty, even damages excavation machinery.In addition,, in the time that the diameter of stub is less than two semicircular hook spacing, two semicircle hooks can only carry out hook to the coring of cross growth and pull out, and can not effectively grab card to upright stub, have limited this device and have eradicated except the application in operation at Trees with Small Diameters.
Utility model content
The technical problem that utility model will solve: a kind of tree root digging cutter is provided, and this tree root digging cutter can become flap by the splitting of large diameter tree root pile, pulls out one by one, longer coring is cut into segment to be dug out, the tree root that is applicable to various diameters is pulled out operation, and operating efficiency is high, pulls out effective.
The technical scheme that technical solution problem is taked: a kind of tree root digging cutter, comprise dull and stereotyped pedestal, be provided with and the otic placode of controlling pick machine working arm and being connected in the one side of pedestal, on otic placode, be provided with connecting shaft hole, be provided with two parallel board-like hook-type handle of a knifes at the another side of pedestal, be provided with tree root splitting cutter in the end of hook-type handle of a knife, be provided with tree root cutter along the inner arc limit of hook-type handle of a knife.
As improvement of the present utility model: be also provided with tree root and pull out cutter between two hook-type handle of a knifes, described tree root is pulled out cutter and fixed perpendicular to two hook-type handle of a knife plate faces, blade points to tree root cutter side.
As further improvement of the utility model: described splitting cutter is the fusiformis cutter that bilateral has sword.
Improve as another kind of the present utility model: be provided with wedge shape expansion projection at splitting cutter knife face, expand protruding root and the welding of hook-type handle of a knife end.
Further improve again as of the present utility model: described tree root cutter are arcuate blade tulwar.
As preferred plan of the present utility model: the angle that tree root is pulled out blade and base plane is 30-80 degree.
Beneficial effect: tree root digging cutter of the present utility model, owing to having adopted described tree root digging cutter to comprise dull and stereotyped pedestal, be provided with and the otic placode of controlling pick machine working arm and being connected in the one side of pedestal, on otic placode, be provided with connecting shaft hole, be provided with two parallel board-like hook-type handle of a knifes at the another side of pedestal, be provided with tree root splitting cutter in the end of hook-type handle of a knife, be provided with the technical scheme of tree root cutter along the inner arc limit of hook-type handle of a knife, when work, utilize the tree root splitting cutter of hook-type handle of a knife end to become many lobes to pull out one by one the splitting of large diameter tree root pile, alleviate the resistance of pulling out, make the operation of this tree root digging cutter not limited by pile diameter, go for the operation of pulling out of major diameter tree root, tree root cutter can cut off coring like a cork in the time hooking lagen palpus, make pile break away from coring constraint and can be pulled out smoothly, simultaneously, coring after cut-out is also more easily ticked from soil, therefore, tree root digging cutter of the present utility model is applicable to larger-diameter tree root and pulls out operation, operating efficiency is high, pull out effective, and, due to the pile after pulling out and coring volume and weight less, be conducive to transport and handling operation, between two hook-type handle of a knifes, be also provided with tree root and pull out cutter owing to having adopted, described tree root is pulled out cutter and is fixed perpendicular to two hook-type handle of a knife plate faces, blade points to the technical characterictic of tree root cutter side, make on the one hand tree root pull out cutter and can cut off the coring that tree root cutter can not cut direction, tree root is pulled out cutter and the pile between two tree root cutter can be peeled off and shoveled out from main body on the other hand, in addition, tree root is pulled out the pile that cutter also can be less than diameter two tree root cutter spacing and is shoveled out, in further increasing work efficiency, expand the scope of application to minor diameter tree root, be the technical characterictic that bilateral has the fusiformis cutter of sword owing to having adopted described splitting cutter, make splitting cutter multi-angle carry out splitting or cutting to pile, and resistance is less in the time that splitting cutter inserts pile, be provided with wedge shape expansion projection owing to having adopted at splitting cutter knife face, expand the technical characterictic of protruding root and the welding of hook-type handle of a knife end, not only strengthen the bonding strength of splitting cutter and hook-type handle of a knife, and be pushed to both sides at the timber that wedge shape is expanded splitting cutter both sides under protruding ramp effect, splitting is opened rapidly, the better effects if of splitting, be the technical characterictic of arcuate blade tulwar owing to having adopted described tree root cutter, make blade and coring can keep good cutting angle, better to the cutting effect of coring, owing to reasonably defining tree root and pull out the angle of blade and base plane, make tree root pull out the movement locus that cutter can adapt to working arm of excavating machine end, make tree root pull out operation and be easier to operation.
