The perching knife that the utility model provides, owing to being provided with the abrasion-proof rib of many spaces settings at the inner surface of perching knife body, perching knife is in the time shoveling native operation, the flow through inner surface of perching knife body of soil under blade shovel or sandstone, under abrasion-proof rib effect, the rubbing machine meeting of soil or sandstone and perching knife body inner surface can be reduced, the wearing and tearing of perching knife body can be greatly reduced; In addition, abrasion-proof rib also has guide effect, has improved the mobility of soil and sandstone, has further reduced wearing and tearing.
Accompanying drawing explanation
The accompanying drawing that forms a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the installation form schematic diagram that the utility model specific embodiment is merely able to perching knife;
Fig. 2 is the structural representation of perching knife in the utility model specific embodiment.
The specific embodiment
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the utility model can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.The left and right of " left and right " mentioned herein during just to Fig. 2.
As illustrated in fig. 1 and 2, the utility model specific embodiment provides a kind of perching knife 1, be installed on land leveller, this perching knife 1 comprises perching knife body 11 and blade, blade comprises side blade 13 and main blade 12, side blade 13 is arranged on the two ends, left and right of perching knife body 11, and main blade 12 is arranged on the lower limb of perching knife body 11, and the inner surface of perching knife body 11 is provided with the abrasion-proof rib 14 that many spaces arrange.Owing to being provided with the abrasion-proof rib 14 of many spaces settings at the inner surface of perching knife body 11, perching knife 1 is in the time shoveling native operation, the flow through inner surface of perching knife body 11 of soil under blade shovel or sandstone, under abrasion-proof rib 14 effects, the rubbing machine meeting of soil or sandstone and perching knife body 11 inner surfaces can be reduced, the wearing and tearing of perching knife body 11 can be greatly reduced; In addition, abrasion-proof rib 14 also has guide effect, has improved the mobility of soil and sandstone, has further reduced the wearing and tearing of perching knife 1.
It should be noted that, gap length between adjacent two abrasion-proof ribs 14 can be determined according to the size of concrete perching knife 1 or Specific construction operating mode, for example, and in shovel sandstone, now the gap between adjacent two abrasion-proof ribs 14 will be larger, be conducive to like this guiding trafficability characteristic of sandstone; In addition, the gap length between many abrasion-proof ribs 14 can be not identical, and even the width size of the diverse location in same gap also can be different.
Preferably, abrasion-proof rib 14 comprises many, wherein a part is arranged on the left end of the inner surface of perching knife body 11, remainder is arranged on the right-hand member of the inner surface of perching knife body 11, and perching knife body 11 middle parts can not established abrasion-proof rib 14, feature while work according to perching knife 1, the soil being shoveled or sandstone are along with the movement of perching knife 1, can flow to the end positions of perching knife 1, the most serious to the wearing and tearing at perching knife 1 two ends like this, therefore only abrasion-proof rib 14 need to be arranged on to the two ends of perching knife body 11, so, saved the quantity of wear rib, and the wearing and tearing of perching knife body 11 are reduced.
In addition, abrasion-proof rib 14 is inclined on perching knife body 11, abrasion-proof rib 14 acutangulates setting with the length direction of perching knife body 11, as shown in Figure 2, preferably, the abrasion-proof rib 14 of perching knife body 11 left ends tilts towards the upper left corner of perching knife body 11, the abrasion-proof rib 14 of perching knife body 11 right-hand members tilts towards the upper right corner of perching knife body 11, meet like this rule that flows to of soil and sandstone, when having improved guidance quality, reduced the wearing and tearing of perching knife 1; The abrasion-proof rib 14 of perching knife 1 every end is parallel to each other, and can further increase like this guidance quality of soil and sandstone.
It should be noted that, abrasion-proof rib 14 can be fixedly installed on the inner surface of perching knife body 11, for example, and welding, or by draw-in groove clamping, or be spirally connected by screw; Also dismountable inner surface that is arranged on perching knife body 11 as required, for example, perching knife body 11 and abrasion-proof rib 14 be suitable for reading has multiple screws, between abrasion-proof rib 14 and perching knife body 11, be bolted, bolt by from the cooperation of different screw, adjust the position on perching knife body 11 of abrasion-proof rib 14, thereby can regulate the size in gap between adjacent two abrasion-proof ribs 14, thus the demand of satisfied different construction operating modes.In addition, the cross section of abrasion-proof rib 14 can be arbitrary shape, is preferably rectangle or circle.
Preferably, for example further reduces the wearing and tearing of perching knife 1, the inner surface of perching knife body 11 that can also be between adjacent two abrasion-proof ribs 14 is also provided with the wear-resisting jut of dispersion.
The utility model specific embodiment also provides a kind of land leveller, comprises hitch frame and above-mentioned any one perching knife 1, and perching knife 1 is arranged on below hitch frame.Due to the above-mentioned beneficial effect of perching knife 1, this land leveller also has above-mentioned beneficial effect, does not repeat them here.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
