Abstract
The utility model discloses a cutterhead of a ditching machine. The cutterhead comprises a rim, spokes, a shaft sleeve and a cutter handle; the center hole in the shaft sleeve is matched with a cutterhead driving shaft of a gearbox of the ditching machine; the shaft sleeve is connected with the spokes; the spokes are connected with the rim; the rim is welded with the cutter handle; and the rim and the spokes are formed by steel tubes with hollow structures. The weight of the cutterhead can be reduced, the gravitational torque in front of a walking tractor is reduced, the impact force generated during clutch engagement is reduced and the cost is saved.
Description
Technical field
The utility model relates to the agricultural machinery field, especially relates to a kind of and front positioning type field furrower parts walking tractor matching.
Background technology
Existing cutter-head of machine for making furrows is to be welded with solid round steel.It is many that this structure consumes material, relatively heavier, therefore just produces three shortcomings: first; Increased the place ahead gravitational moment of trench digging unit, front-end ditching machine can only use with walking tractor matching, is installed in hand tractor the place ahead again only; Original hand tractor front and back are balances; But because it is just very heavy that the place ahead has been installed behind the ditching machine, so the pressure of the handrail handle that makes the operator in use will strengthen down to press the hand tractor is relatively painstakingly.The second, cutterhead weight is greatly that quality is also big, and rotator inertia is also bigger, the impulsive force the during combination that strengthened clutch.The 3rd, it is many to consume steel, has increased cost.
Summary of the invention
The utility model overcomes the deficiency of prior art, and a kind of cutter-head of machine for making furrows is provided, and can alleviate the weight of cutterhead, alleviates the gravitational moment in hand tractor the place ahead, and the impulsive force when reducing the clutch combination also helps practicing thrift cost.
The technical scheme that the utility model adopts is following:
A kind of cutter-head of machine for making furrows; Comprise wheel rim, spoke, axle sleeve and handle of a knife, the centre bore in the said axle sleeve cooperates with the cutter plate driver axle of ditching machine gear-box, is connected with spoke on the said axle sleeve; Spoke is connected with wheel rim; Be welded with handle of a knife on the wheel rim, said wheel rim and spoke are that steel pipe constitutes, and steel pipe is the steel pipe of hollow structure.
Beneficial effect: after the utility model adopted the steel pipe welding cutterhead of hollow, weight can alleviate near half the, the cutterhead that prior art is done with the filled circles steel of 20 millimeters of diameters, and 10.5 kilograms of weight are according to 4.6 yuan of/kilogram calculating of present steel valency, 48.3 yuan of fee of materials.By the patent art scheme as with 3.0 millimeters of wall thickness, the cutterhead of the steel pipe manufacturing that external diameter is 22 millimeters, intensity is identical; But weight has only 6 kilograms, reduces nearly half the weight, is 5.0 yuan of/kilogram calculating according to present steel pipe price; Be 30 yuan, practice thrift 18 yuan, practice thrift cost more than 30%.
Description of drawings
Fig. 1 is the utility model cutter-head of machine for making furrows structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
As shown in Figure 1: a kind of cutter-head of machine for making furrows; Comprise wheel rim 1, spoke 2, axle sleeve 3 and handle of a knife 4, the centre bore in the said axle sleeve 3 cooperates with the cutter plate driver axle of ditching machine gear-box, is connected with spoke 2 on the said axle sleeve 3; Spoke 2 is connected with wheel rim 1; Be welded with handle of a knife 4 on the wheel rim 1, said wheel rim 1 constitutes for steel pipe with spoke 2, and steel pipe is the steel pipe of hollow structure.
Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.The all available prior art of each part not clear and definite in the present embodiment realizes.
