Abstract
The utility model is related to a kind of bulldozer perching knife cutter head with intervening guard, including bit body；The intermediate region top of bit body front end has additional a protective plate, and the shape of protective plate is forward trapezoidal for a short side, and the shape of protective plate, the shape of size and bit body front end, size match；An at least middle reinforced rib and two side reinforcing ribs are convexly equipped on the back side of protective plate, middle reinforced rib is located at the intermediate region of protective plate, two side reinforcing ribs are located at the two sides of protective plate respectively, side reinforcing rib and the equal hospital areas of middle reinforced rib are connected on protective plate, and another end regions are connected on bit body.The utility model installs protective plate additional in the middle upper portion of bit body, can prevent the earthwork from climbing over cutter head from centre, causes top product soil, can also make a cubic metre of earth forward upward rolling, increase soil-shifting capacity；It can prevent object from being fallen from front simultaneously, play a protective role to tilting pipeline and lift cylinder.
Description
Technical field
The utility model belongs to earthmoving vehicles, and in particular to a kind of bulldozer perching knife cutter head for engineering machinery, especially
It is related to a kind of bulldozer perching knife cutter head with intervening guard.
Background technology
Referring to attached drawing 1, the usually used bulldozer perching knife cutter head of bull-dozer is generally divided into standard type and wetland type at present, and one
As cutter head mainly by knife plate, back reinforcing plate, dump ram connects bearing, bearing diagonal connects bearing, horizontally-supported bearing, push away
Bar connects bearing, lift cylinder bearing composition.But during bull-dozer works, can all there are the earthwork or other objects from cutter head
Top climbs over, and causes top largely product soil, and the serious object to roll from front, which smashes, tilts pipeline and lift cylinder, to whole
The performance of machine causes serious damage or even influences the normal work of machine, and there are the risks of reliability.As shown in Figure 1
Traditional bulldozer perching knife cutter head not only causes perching knife top product soil without intervening guard, can also be because of the object that top is rolled
Pipeline and lift cylinder are damaged, there are reliability shortfall risks.
In consideration of it, propose that a kind of bulldozer perching knife cutter head with intervening guard is the class to be studied of the utility model
Topic.
Utility model content
For solve the prior art due to bulldozer perching knife cutter head without intervening guard deficiency, cause perching knife top seriously product soil and
The defects of earthwork climbs over perching knife, the utility model provides a kind of bulldozer perching knife cutter head with intervening guard, including cutter head sheet
Body；
It is characterized in that：The intermediate region top of the bit body front end has additional a protective plate, the protective plate
Shape is forward trapezoidal for a short side, and the shape of protective plate, the shape of size and bit body front end, size match；
An at least middle reinforced rib and two side reinforcing ribs, the intermediate reinforcement are convexly equipped on the back side of the protective plate
Muscle is located at the intermediate region of protective plate, and described two side reinforcing ribs are located at the two sides of protective plate respectively, and the side adds
Strengthening tendons and the equal hospital areas of middle reinforced rib are connected on protective plate, and another end regions are connected on bit body.
Further, the middle reinforced rib is set to five, and five middle reinforced ribs are along protective plate between width
Every arrangement.
Further, the connection of the middle reinforced rib and protective plate and bit body is welding.
Further, the middle reinforced rib is laminated structure, the welding edge of the laminated structure, a part and protective plate weldering
It connects, another part is welded with bit body.
Further, the side reinforcing rib is the sheet reinforcing rib of bending, and the wrap direction of two side reinforcing ribs
Towards protective plate center to form an encirclement structure.
Advantageous effect：The utility model installs protective plate additional in the middle upper portion of bit body, and one can prevent the earthwork therefrom
Between climb over cutter head, cause top product soil, the rolling of cubic metre of earth forward upward can also be made, increase soil-shifting capacity；Two can prevent object
It is fallen from front, falls on and tilt above pipeline and lift cylinder, played a protective role to tilting pipeline and lift cylinder.

Attached drawing 2 is the schematic diagram for the bull-dozer cutter head that the present embodiment has intervening guard；
Attached drawing 3 is the front view for the bull-dozer cutter head that the present embodiment has intervening guard.
In the figures above：1st, bit body；2nd, side reinforcing rib；3rd, protective plate；4th, middle reinforced rib.
Specific embodiment
Embodiment：A kind of bulldozer perching knife cutter head with intervening guard
As Figure 2-3, including bit body 1, the intermediate region top of 1 front end of bit body has additional a protection
Plate 3, the shape of the protective plate 3 is forward trapezoidal for a short side, and 1 front end of the shape of protective plate 3, size and bit body
Shape, size match.
Five middle reinforced ribs 4 and two side reinforcing ribs 2 are convexly equipped on the back side of the protective plate 3, five centres
For reinforcing rib 4 along 3 width arranged for interval of protective plate, the middle reinforced rib 4 is respectively positioned on the intermediate region of protective plate 3, described
Two side reinforcing ribs 2 respectively be located at protective plate 3 two sides, 4 homogeneous petiolarea of the side reinforcing rib 2 and middle reinforced rib
Domain is connected on protective plate 3, and another end regions are connected on bit body 1.
In the present embodiment, the connection of the middle reinforced rib 4 and protective plate 3 and bit body 1 is welding.The centre adds
Strengthening tendons 4 is laminated structure, and the welding edge of the laminated structure, a part of to be welded with protective plate 3, another part is welded with bit body 1
It connects.
The side reinforcing rib 2 is the sheet reinforcing rib of bending, and the wrap direction of two side reinforcing ribs 2 is towards anti-
3 center of backplate is to form an encirclement structure.
In the present embodiment there is the bulldozer perching knife cutter head of intervening guard, solve at present that be widely present perching knife top serious
The problem of product soil and the earthwork climb over perching knife, and also avoid the physical damage dump ram pipeline climbed over from perching knife top and carry
The risk of oil-lifting jar reduces the failure rate of complete machine, saves the maintenance cost in later stage.
The utility model is described in detail above, it is described above, be only the utility model preferred embodiment and
, it is when the utility model practical range cannot be limited, i.e., all to make equivalent changes and modifications according to the application scope, it all should still belong to this
In utility model covering scope.
