Description
Technical field
The utility model relates to a kind of land leveller and bull-dozer and snowplow cutter heads, belong to municipal works and building
Technical field of engineering machinery.
Background technique
With the high speed development that highway in China is built, especially County Highway is even more to have obtained development at full speed in recent years,
Highway construction and maintenance department are more more and more urgent to the plant device requirement of related municipal works and highway structure；Wherein
Including the engineering machinery such as land leveller and bull-dozer and snowplow, needed to configure on these mechanical equipments on multiple tool aprons, and
A kind of cutter head structure being installed to by tool apron on base body.Point of a knife in existing cutter head structure is carrying out operation to ground etc.
When, because cutter head structure design is not reasonable, it is easy to keep cutter head stress impaired, influences the service efficiency of engineering mechanical device, increase
Use cost reduces the using effect of engineering mechanical device.
Summary of the invention
The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a kind of simple and reasonable for structure, make
With easy for installation, wearability is good, and cutter head hardness is big, and service life greatly increases, and so as to improve working efficiency, reduces and uses
The land leveller and bull-dozer and snowplow cutter head of cost.
The purpose of this utility model is completed by following technical solution, a kind of land leveller and bull-dozer and snowplow
With cutter head, it is made of rod-shaped knife handle and blocky cutter hub disjunctor, and the upper surface of the bulk cutter hub is provided with one from rear end
Portion makes front end face leave the operative end surface of a strip diagonally downward to the inclined-plane of front end face；It is set on the inclined-plane
It is equipped with the recessed groove of an indent, and is provided with inside bar shaped groove in the operative end surface of the strip, and at this
The hard alloy blocks that outer end is exposed at operative end surface are embedded in shape through slot；The front end of the rod-shaped knife handle is integrally attached to block
Among the rear end face of shape cutter hub, the rear end of rod-shaped knife handle be vertically disposed with it is parallel with the axis center of rod-shaped knife handle, in recessed
Planar fitting surface is lacked, vertically-mounted through-hole is provided on the fitting surface.
As preferred: the inclined-plane of the bulk cutter hub is the curve slope for showing slightly indent, and the bottom surface of blocky cutter hub is inclination
Upward inclined end face, tilt angle are not more than 30 °；The operative end surface of the bulk cutter hub is also from top to bottom outer
Convex inclined plane, and the bar shaped groove for being embedded with hard alloy blocks is provided with perpendicular to the outer convex inclined plane, and described hard
It is circular outer ends side that matter alloy block, which is exposed at operative end surface,；The front end of the rod-shaped knife handle passes through arc-shaped transition integrally connected
Among the rear end face of blocky cutter hub.
The utility model belongs to improvements over the prior art, it have it is simple and reasonable for structure, it is easy to install and use, it is wear-resisting
Property it is good, cutter head hardness is big, and service life greatly increases, so as to improve working efficiency, the features such as reducing use cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is A direction view in Fig. 1.
Fig. 3 is B direction view in Fig. 1.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing: shown in Fig. 1-3, one kind described in the utility model
Land leveller and bull-dozer and snowplow cutter head, it is made of rod-shaped knife handle 1 and blocky 2 disjunctor of cutter hub, the bulk cutter hub 2
Upper surface be provided with one from rear end diagonally downward to the inclined-plane of front end face 3, and front end face is made to leave a strip
Operative end surface 4；The recessed groove 5 of an indent is provided on the inclined-plane 3, and in the operative end surface of the strip 4
It is provided with inside bar shaped groove 6, and is embedded in the bar shaped groove 6 hard alloy that outer end 7 is exposed at operative end surface 4
Block 8；The front end of the rod-shaped knife handle 1 is integrally attached among the rear end face 9 of blocky cutter hub 2, and in the rear end of rod-shaped knife handle 1
10 be vertically disposed with it is parallel with rod-shaped 1 axis center of knife handle, in the planar fitting surface 11 of notch, and on the fitting surface 11
It is provided with vertically-mounted through-hole 12.
As shown in the figure, the inclined-plane 3 of the blocky cutter hub 2 is the curve slope for showing slightly indent, and the bottom surface 13 of blocky cutter hub 2 is
The inclined end face tilted upward, tilt angle are not more than 30 °；It is described bulk cutter hub 2 operative end surface 4 be also one on to
Under outer convex inclined plane, and the bar shaped groove 6 for being embedded with hard alloy blocks 8 is arranged perpendicular to the outer convex inclined plane, and
It is circular outer ends side that the hard alloy blocks 8, which are exposed at operative end surface 4,；The front end of the rod-shaped knife handle 1 passes through arc mistake
14 are crossed to be integrally attached among the rear end face of blocky cutter hub 2.
The utility model is embedded in strip hard alloy blocks in the operative end surface of blocky cutter hub, increases the wear-resisting of product
Property, substantially increase the service life of product.
