Abstract
The utility model discloses a rear - mounted ditching machine blade disc, the especially rear - mounted ditching machine blade disc that supporting hand tractor used, form including blade disc former, blade disc axle sleeve, dead knife handle and sharpener handle, basin type or cymbals form are made to blade disc outer fringe to well mind -set axial one side progressively arch, and bellied one side welding of blade disc center or riveting have a blade disc axle sleeve, the peripheral welding of blade disc outer fringe or riveting know how things stand and feel confident handle of a knife, sharpener handle, the blade disc former adopt the tensile or the whole cast of steel plate stamping to form.
Description
Technical field
The utility model relates to field of agricultural machinery, especially relates to rear-mounted field furrower parts that are a kind of and walking tractor matching.
Background technology
What existing rear digging machine adopted is the cylinder cutterhead that a kind of steel pipe is made, see the patent No.: 201310743234.0, the shortcoming that this structure exists is: the first, assembling is very inconvenient, dismounting often could realize with professional tool such as nigger spanner etc., user in rural area, farm work, condition is poor, is difficult to accomplish; The second, why cutterhead adopts steel pipe manufacturing to become cylinder shape, because rear digging machine have employed the general gearbox assembly of front-end ditching machine, cutter axis on gear-box is shorter, and rear digging machine mud guard nestles up gearbox assembly, must need cutter axis to extended length, make the blade on cutterhead and cutterhead leave mud guard certain distance, could user demand be met; In addition owing to being subject to the restriction of diameter of steel tube, cause cutterhead external diameter little, ditching depth is shallow, if open zanjon, gear case of ditcher and belt pulley will inevitably be made near ground thus impact use during operation.
In existing furrowing machine knife disk technology; also the cutterhead adopting flat panel production is had; see the patent No.: 201120179287 and the patent No.: 201320812319 etc.; this cutterhead axial strength is low; particularly user is in trench digging process; in order to correct ditch shape linearity; usually suddenly can pull hand tractor handrail even grabbing steering tiller; make cutterhead side to stressed; the as easy as rolling off a log cutterhead lateral thrust that causes is out of shape, and cutterhead is once distortion, and overall center of gravity is uneven; can vicious circle be produced again under high-speed rotation, finally cause cutterhead to damage.
In existing furrowing machine knife disk technology, also have the cutterhead adopting round steel seam to be made, see the patent No.: 201410343188, although the scheme intensity that this cutterhead makes is good, due to complex structure, welding requirements is high, also cumbersome in technique.
Utility model content
The utility model does not overcome the deficiencies in the prior art, and provide a kind of easy accessibility simple, cutter diameter is relatively large, adapts to the assembling with universal assembly, good, the shock resistance of intensity simultaneously, yielding, manufactures also rear digging machine cutterhead very easily.
The technical solution adopted in the utility model is as follows:
A kind of rear digging machine cutterhead, is made up of cutterhead former, cutterhead axle sleeve, bed plate handle and sharpener handle, and cutterhead former outer rim is progressively protruded to axial side to center and is made into basin type or cymbals shape, and the side that cutterhead former center is protruded is welded with cutterhead axle sleeve.Cutterhead former outer perimeter is welded with bed plate handle and sharpener handle.Cutterhead former adopts steel plate punched to stretch and makes.
As preferably, described cutter-head of machine for making furrows, the side riveted joint that cutterhead former center is protruded has cutterhead axle sleeve.The riveted joint of cutterhead former outer perimeter has bed plate handle and sharpener handle.Cutterhead former adopts monoblock cast to form.
Beneficial effect: the utility model adopts this novel cutterhead, cutterhead former adopts steel plate to make, progressively protrude to cutter axis to side punching stretch from outer rim to center and make basin type or cymbals shape, due to the axial distance increasing cutterhead that this structure is covert, to make after this cutterhead and existing universal general assembly from ditching machine mud guard, apart from far, the normal operation of cutterhead can not be affected; Steel plate makes the obstacle that cutterhead also overcomes prior art steel pipe manufacturing cutterhead, cannot do larger by cutterhead external diameter by the constraint of diameter of steel tube, after cutter diameter strengthens, when opening zanjon operation, gear case of ditcher and belt pulley can not be made near ground thus impact use.Thisly protrude the basin type or cymbals shape cutterhead made to side punching stretch, also solve the problem of slab construction intensity deficiency, bulk strength is better, simultaneously also very convenient with the installing/dismounting of gear-box cutter axis.From the manufacturing process of cutterhead, structure is relatively simple, adapts to mass production.
Accompanying drawing explanation
Fig. 1 is front schematic view of the present utility model.
Fig. 2 is the B-B profile of Fig. 1.
Fig. 3 is the first schematic perspective view of the present utility model.
Fig. 4 is the second schematic perspective view of the present utility model.
Wherein, 1 cutterhead former, 2 cutterhead axle sleeves, 3 bed plate handles, 4 sharpener handles.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As Figure 1-4, a kind of rear digging machine cutterhead, comprise cutterhead former 1, cutterhead axle sleeve 2, bed plate handle 3 and sharpener handle 4 and form, cutterhead former 1 outer perimeter is welded with bed plate handle 3 and sharpener handle 4.
Above-mentioned cutterhead former 1 outer rim is progressively protruded to axial side to center and is made into basin type or cymbals shape, and the side that cutterhead former 1 center is protruded is welded with cutterhead axle sleeve 2.
The utility model adopts this rear digging machine cutterhead, and cutterhead former 1 adopts steel plate to make, and progressively protrude to cutter axis to side punching stretch from outer rim to center and make basin type or cymbals shape, cutterhead former 1 outer perimeter is welded with bed plate handle 3 and sharpener handle 4.The side that cutterhead former 1 center is protruded is welded with cutterhead axle sleeve 2.The axial distance of what this structure was covert increase cutterhead, to make after this cutterhead and existing universal general assembly from ditching machine mud guard, apart from far, can not affect the normal operation of cutterhead; Steel plate cutterhead also overcomes the little difficult problem can not opening zanjon of steel pipe cutterhead diameter of steel tube in prior art, and after cutter diameter strengthens, when opening zanjon operation, gear case of ditcher and belt pulley can not ensure normal use near ground.Thisly protrude the basin type or cymbals shape cutterhead made to side punching stretch, also solve the problem of slab construction intensity deficiency, bulk strength is better, simultaneously also very convenient with the installing/dismounting of gear-box cutter axis.From the manufacturing process of cutterhead, structure is relatively simple, adapts to mass production.
It should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle, can also make multiple improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.The all available prior art of each part not clear and definite in the present embodiment is realized.
