Description
Technical field
It is specifically a kind of to take off toothing the present invention relates to railway ballast cleaning-sieving machine excavating gear.
Background technique
Grilled teeth in railway ballast cleaning-sieving machine excavating gear, due to its directly be mined ballast and contact, needed in operation
The effect of biggish shock and vibration load and digging force is born, the digging force that operation grilled teeth is born especially on hardened railway roadbed
Meeting several times increase, in the design process, although having used steel alloy overall structure, for examining for complete machine production cost
Consider, the service life of material is often less than the service life of complete machine other component, causes occur grilled teeth head mill earlier
Damage deformation, need to replace in advance when more than service limits.Rake teeth belongs to basic vulnerable part, and demand is larger, influences the use of complete machine
And maintenance cost.
Summary of the invention
Present invention seek to address that the above problem, to provide, a kind of structure is simple, and low manufacture cost is with long service life to take off
Toothing.
The present invention solves described problem, the technical solution adopted is that:
One kind taking off toothing, including grilled teeth main body, and grilled teeth main body is cylindrical body, and the head of cylindrical body is provided with inclined-plane, the back on inclined-plane
Face is provided with a pair of of diamond shape section.
The present invention by adopting the above technical scheme, compared with prior art, the feature protruded is:
The cylinder body structure of grilled teeth of the present invention, sorting, machining process are simple, are provided with one on the cylindrical body head of grilled teeth
Determine the inclined-plane of angle, it is possible to reduce the friction force generated when grilled teeth cutting ballast is provided with certain altitude at the back side on inclined-plane
A pair of of diamond shape section, when grilled teeth transverse movement, diamond shape corner cut can reduce well cutting ballast active force, change simultaneously
Kind abrasion of the ballast to grilled teeth, structure is simple, low manufacture cost, long service life.
Preferably, the further technical solution of the present invention is:
Groove is provided on diamond shape section, heap is welded with wearing layer in groove, groove is outputed on diamond shape section, to improve hardfacing
Binding force of the layer on grilled teeth body, the build-up wear-resistant layer in groove can be improved the wear-resisting property on diamond shape section surface, extend
Service life.
The lower part of cylindrical body is provided with multiple adjustment locating slots for being used to adjust position height after grilled teeth assembles, for working as grilled teeth
Head generates abrasion in use, when acting on the length of ballast reduces, the mounting height of grilled teeth is turned up, realization is changed without
Under the premise of grilled teeth, extend 2-3 times of the service life of effect.
Detailed description of the invention
Fig. 1 is schematic view of the front view of the embodiment of the present invention；
Fig. 2 is overlooking structure diagram of the embodiment of the present invention；
In figure: cylindrical body 1；Inclined-plane 2；Diamond shape section 3；Groove 4；Adjust locating slot 5；Wearing layer 6.
Specific embodiment:
Below with reference to embodiment, the invention will be further described, and purpose, which is only that, more fully understands the content of present invention, therefore, institute
The example of act is not intended to limit protection scope of the present invention.
Referring to Fig. 1, Fig. 2, one kind taking off toothing, including grilled teeth main body, and grilled teeth main body is cylindrical body 1, the head of cylindrical body 1
It is provided with inclined-plane 2, the back side on inclined-plane 2 is provided with a pair of of diamond shape section 3, groove 4 is provided on diamond shape section 3, heap is welded with wear-resisting in groove 4
Layer 6, the lower part of cylindrical body 1 are provided with multiple for adjusting the adjustment locating slot 5 of position height after grilled teeth assembles.
Grilled teeth main body of the present invention is structure, sorting, the simple cylindrical body 1 of machining process, at cylindrical body 1 of grilled teeth
Portion is provided with the inclined-plane 2 of certain angle, and the friction force generated when can reduce grilled teeth cutting ballast is opened at the back side on inclined-plane 2
There is a pair of of diamond shape section 3 of certain altitude, when grilled teeth cuts ballast to when moving, diamond shape corner cut 3 can reduce well along A
Active force, while improving abrasion of the ballast to grilled teeth, groove 4 is outputed, on diamond shape section 3 to improve wearable overlay in grilled teeth
Binding force on body, heap is welded with wearing layer 6 in groove 4, can be improved the wear-resisting property on 3 surface of diamond shape section, and extension makes
With the service life, multiple adjustment locating slots 5 are provided in 1 lower part of cylindrical body, for generating abrasion in use when grilled teeth head, are made
When length for ballast reduces, the mounting height of grilled teeth is turned up, under the premise of realization is changed without grilled teeth, extends 2-3 times of the service life
Effect, structure is simple, low manufacture cost, long service life.
The foregoing is merely preferably feasible embodiment of the invention, not thereby limiting the scope of the invention,
It is all to use equivalence changes made by description of the invention and its accompanying drawing content, it is intended to be included within the scope of the present invention.
