Abstract

The utility model belonging to the agricultural machinery filed relates to a cutter head of an agricultural ditcher, which consists of a rim, a spoke, a shaft sleeve, a bottom tool shank, a paring tool shank, a bottom cutter and a wall paring cutter. The utility model is characterized in that the paring tool shank of the cutter head is provided with four long trough holes which are divided into two rows and are juxtaposed arranged and transversely staggered by a plurality of distance; the steel plate is applied to punch the paring tool shank into channel steel type; after the technical scheme of the utility model is adopted, two wall paring knives can be assembled at the same time by each paring tool shank; the ditching width of the cutter head is convenient to be adjusted and the balance of the cutter head is largely improved; the cost is low, the fabrication process is simple and the fast batch products are convenient to be produced.

Description

A kind of cutterhead of agricultural ditching machine

Technical field

The utility model belongs to agricultural mechanical field, relates to a kind of cutterhead of agricultural ditching machine.

Background technology

The cutterhead of agricultural ditching machine generally is made up of wheel rim, spoke degree, axle sleeve, bed plate handle, sharpener handle and bed plate, cliff cutter, in the technology of existing ditching machine, can only a cliff cutter be arranged device on each sharpener handle on the cutterhead, and the cliff cutter is fixedly connected with one or two bolt, and the sharpener handle generally all is designed to the same with the bed plate handle square tube shape that is, and often adopts monoblock cast to form; Because the every limit of existing cutterhead only is provided with a cliff cutter, causes the cutterhead imbalance; Even or every limit is provided with two cliff cuttves, can not guarantee to be symmetrical set, therefore in the process of cutterhead high speed rotating operation, the cutterhead imbalance can be brought very big inclined to one side shake, has consumed the power of diesel engine, has also increased the resistance of operation simultaneously; Universal day by day along with ditching machine, use the continuous expansion of ditching machine region, also there is difference various places to the requirement of ditching machine trench digging, the furrow width that the area that has need be opened, and the area that has is then narrow, be not quite similar, even great disparity is bigger, and this just requires the cutterhead of ditching machine can make the adjusting of different furrow widths with regard to different requirements, in the prior art because the groove on the sharpener handle is shorter, can't regulate the bigger range of furrow width, therefore make ditching machine can not adapt to the trench digging needs of different regions; Sharpener handle of the prior art in addition generally is the rectangle sleeve pipe that adopts cast steel to make, complex manufacturing, and speed is slow, also incompatible production fast in batches.

The utility model content

Task of the present utility model provides a kind of cutterhead of ditching machine, to overcome the deficiencies in the prior art, new construction should can solve the equilibrium problem of cutterhead substantially, and strengthened the adjustable range of cutterhead furrow width, make the use operation of trench digging functional adaptation different regions, new construction should adopt new production technology simultaneously, can produce fast, and cost is low, and manufacturing process is simple.

The design's technical scheme is: a kind of new sharpener handle is set on the cutterhead of ditching machine, it is characterized in that the sharpener handle is provided with four long slot bores, the sharpener handle adopts steel plate to strike out channel steel shape.Four long slot bores are that two rows be arranged in parallel, on every sharpener handle two cliff cuttves can be installed side by side, and four elongated slots have the adjustable range of big length, and the cliff cutter can adapt to the needs of different furrow width requirements when being installed on sharpener handle adjusted width; In order to strengthen the adjustable range of furrow width cleverly, arrange the elongated slot lateral alternate certain distance of fixed center distance separately with two when elongated slot is set, according to the needs of different regions can by about, symmetry changes the outfit the method for cliff cutter to reach the maximum magnitude of regulating furrow width.

The design has overcome the deficiencies in the prior art, and new construction can solve the equilibrium problem of cutterhead substantially, and resistance is little during ditching operation, has reduced unnecessary power consumption, and has strengthened the adjustable range of cutterhead furrow width, makes the operation of trench digging functional adaptation different regions; Because the sharpener handle of new construction adopts punching press to be made into channel steel shape, manufacturing process is simple, produce fast, and cost is low.

Now be described further with embodiment in conjunction with the accompanying drawings.

Description of drawings

Fig. 1 is the design's an overall structure schematic diagram;

Fig. 2 overlooks cut-away illustration for the A-A that Fig. 1 removes behind the sharpener.

Embodiment

Embodiment 1, and with reference to Fig. 1: the cutterhead of ditching machine is made up of wheel rim 1, spoke 2, axle sleeve 3, bed plate handle 4, sharpener handle 5 and bed plate 6, cliff cutter 7; With reference to Fig. 2: sharpener handle 5 is provided with four elongated slots of two rows arranged side by side, and two arrange the elongated slot lateral alternate certain distance of fixed center distance separately.Owing to adopted two groups of four cliff cuttves 7 on the cutterhead, use cutterhead balance when work better, cliff cutter 7 is installed on the sharpener handle 5 can pass through elongated slot lateral adjustments width, adapting to the needs of different furrow widths, can also by about, symmetry changes the outfit the method for four cliff cuttves 7 to reach the maximum magnitude of regulating furrow width.Sharpener handle 5 adopts the disposable channel steel shape that strikes out of steel plate, and cost is low, and manufacturing process is simple, can adapt to need of rapid production.

Claims

1. the cutterhead of an agricultural ditching machine is made up of wheel rim, width of cloth bar, axle sleeve, bed plate handle, sharpener handle and blade, it is characterized in that: the sharpener handle is provided with four long slot bores.

2. according to the cutterhead of the said a kind of agricultural ditching machine of claim 1, it is characterized in that: four long slot bores on the sharpener handle are divided into two rows and are set up in parallel and the lateral alternate certain distance.
