Abstract
The utility model provides a technical plan of cutting cutterhead for trenchers. The plan comprising a cutterhead with a shaft hole and a blade fixed on the arbor is characterized in that the tool holder with 5-30 cm in radial width is fixed on the outer of the disc cutterhead where at least two columns of plural arbor equipped with blades are in circular uniform distribution and the axis of the shaft is within the normal plane of the corresponding cutterhead. The shaft line of the arbor outside the tool holder thereon inclines outwards. The inclination angle is the smallest alpha between the shaft line of arbor and cross section of the knife base worth between 0.3 and 5 degrees. A supporting rod is placed between the upper part of the arborand the knife base, which is joint with the upper part of arbor at one end and with the knife base of next arbor. The knife blade is made of hard aluminium alloy.
Description
Affiliated technical field:
The utility model relates to the trench trench digging mechanical part of pipeline such as a kind of underground installation cable, especially a kind of ditching machine cutter plate.
Background technology:
In the prior art, technique known is an existing bull ditcher excavation dish, the structure more complicated of this excavation dish, and the wider width of trench digging is generally all more than 50 centimetres.The ditch of width like this, concerning burying cable etc. underground the pipeline of about 20 centimetres of diameters, just a bit too wide.And the earth volume of excavation is big, and therefore, the earth volume of backfill is also big.Cause take a lot of work, time-consuming and increase construction cost, this is the existing in prior technology weak point.
Summary of the invention:
The purpose of this utility model, be exactly at the existing in prior technology deficiency, and a kind of ditching machine cutter plate technical scheme is provided, this scheme adopts on cutterhead fixedly tool rest, the knife bar that on tool rest, fixedly has cutter head, make structure very simple, be particularly suitable for the excavation of burying trench underground of cable or diameter less than 20 centimetres of pipelines, and, the earth volume of excavating is little, backfill is also easy, and the saving of labor also saves time, and has reduced construction cost again.
This programme is realized by following technical measures: comprise on the cutterhead that has the cutter shaft hole and the knife bar that fixing cutter head is arranged, the characteristics of this programme are that the periphery at circular beater plate is fixed with tool rest, the axial width H of this tool rest is between 5-30 centimetre, be fixed with the knife bar of at least two rows by the equally distributed a plurality of belt blade heads of circumference on the outer circumference surface of tool rest, the axis of this knife bar is in the normal plane of this place's cutterhead.The concrete characteristics of this programme also have, and the axis of the described tool rest outside two row's knife bars is outward-dipping, and the angle of inclination is that the axis of knife bar and the minimum angle α between the tool rest cross section are between the 0.3-5 degree.Also have support bar between the top of described knife bar and tool rest, this support bar one end is fixedlyed connected with the top of knife bar, and the other end is fixedlyed connected with the tool rest of adjacent next knife bar side.What described cutter head adopted is carbide alloy moulding cutter head.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme, periphery at circular beater plate is fixed with tool rest, the axial width H of this tool rest is between 5-30 centimetre, be fixed with the knife bar of at least two rows by the equally distributed a plurality of belt blade heads of circumference on the outer circumference surface of tool rest, the axis of this knife bar is in the normal plane of this place's cutterhead.The structure of this scheme is very simple, be particularly suitable for the excavation of burying trench underground of cable or diameter less than 20 centimetres of pipelines, can bury the requirement of pipeline as required underground, select the width of tool rest, thereby the earth volume that can implement to excavate reduces as best one can, backfill also just easily, reaches the saving of labor and also saves time, and has reduced construction cost again.Because the outward-dipping little angle of axis of the described tool rest outside two gang feed tool racks make the trench both sides of the edge of leaving neat, and the surplus soil of bottom of trench is few, is easy to pipeline and installs.In addition, between the top of knife bar and tool rest, also have support bar, this support bar guaranteed knife bar when work firmly.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the structural representation of the utility model specific embodiment.
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
Among the figure, 1 is the cutter shaft hole, and 2 is cutterhead, and 3 is tool rest, and 4 is support bar, and 5 is cutter head, and 6 is knife bar.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
By accompanying drawing as can be seen, the ditching machine cutter plate of this programme comprises on the cutterhead (2) that has cutter shaft hole (1) and the knife bar (6) that fixing cutter head (5) is arranged, and what described cutter head (5) adopted is carbide alloy moulding cutter head.This programme is that the periphery at circular beater plate (2) is fixed with tool rest (3), and the axial width H of this tool rest (3) is between 5-30 centimetre, and what the tool rest of this specific embodiment (3) width adopted is 12 centimetres.Be fixed with the knife bar (6) of at least two rows by the equally distributed a plurality of belt blade heads of circumference (5) on the outer circumference surface of tool rest (3), the axis of this knife bar (6) is in this locates the normal plane of cutterhead (2).The axis of described tool rest (3) outside two row's knife bars (6) is outward-dipping, the angle of inclination be axis and the minimum angle α between tool rest (3) cross section of knife bar (6) between the 0.3-5 degree, what the angle of this specific embodiment adopted 2 spends.Also have support bar (4) between the top of described knife bar (6) and tool rest (3), these support bar (4) one ends are fixedlyed connected with the top of knife bar (6), and the other end is fixedlyed connected with the tool rest (3) of adjacent next knife bar (6) side.
Claims (4)
1. ditching machine cutter plate, comprise on the cutterhead that has the cutter shaft hole and the knife bar fixing cutter head is arranged, it is characterized in that: the periphery at circular beater plate is fixed with tool rest, the axial width H of this tool rest is between 5-30 centimetre, be fixed with the knife bar of at least two rows by the equally distributed a plurality of belt blade heads of circumference on the outer circumference surface of tool rest, the axis of this knife bar is in the normal plane of this place's cutterhead.
