Description
Technical field
This utility model relates to a kind of grab bucket mechanism, particularly to a kind of coal grab novel grab bucket mechanism.
Background technology
Existing coal grab grab bucket mechanism includes installing rack of grabbing bucket, and in grab bucket installing rack lower end, symmetrical hinged two shells are grabbed
Bucket, is symmetrically arranged on two with, at grab bucket installing rack, the driving oil cylinder that two ends are hinged with grab bucket installing rack and grab bucket respectively.Owing to being subject to
The rotation amplitude of shell grab bucket and the flexible travel limit of driving oil cylinder, therefore drive the cylinder rod lower end of oil cylinder to grab bucket with shell
Pin joint near homonymy shell grab bucket with grab bucket installing rack pin joint, so drive hydraulic oil cylinder driving shell grab bucket rotation time
Its arm of force is shorter, drives cylinder efficient laborious, needs to configure big specification cylinder.
Secondly, shell grab bucket cutting edge is that a pair common flat sword is symmetrically welded at two grab bucket lower limbs, passes through two when grabbing coal
A pair flat sword in individual grab bucket cooperates and realizes crawl to material.Coal seam owing to being deposited in railway carriage is thicker, when
When temperature is relatively low, easily harden in coal seam, and particularly winter is all the more so.Now, during coal grab work grab bucket insert coal seam will ten
Divide laborious, not only have a strong impact on work efficiency, easy material leakage, and if things go on like this can reduce the hydraulic cylinder driving grab bucket to rotate and make
Use the life-span.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of rational in infrastructure, drives cylinder efficient laborsaving, it is possible to
Make to grab coal time saving and energy saving, improve the coal grab novel grab bucket mechanism of work efficiency.
For solving the problems referred to above, this utility model adopts the following technical scheme that
A kind of coal grab novel grab bucket mechanism, including grab bucket installing rack, symmetrical hinged two shellfishes in grab bucket installing rack lower end
Shell is grabbed bucket, and it is characterized in that: be symmetrically arranged on two with two link assemblies being hinged, two link assemblies at grab bucket installing rack
One end be hinged on the top of grab bucket installing rack, the other end of two link assemblies is hinged on the upper center of the same side shell grab bucket
At outer rim, it is connected to drive oil cylinder, at two between jointed shaft and the grab bucket installing rack in the middle part of two link assemblies
The serrated cutting edge that relative lower edge after shell grab bucket Guan Bi is respectively equipped with on serrated cutting edge, and two shell grab buckets is mutual
Occlusion.
As further preferably, cylinder body one end of described driving oil cylinder is respectively hinged at grab bucket installing rack and grabs bucket it with shell
Between jointed shaft on, drive oil cylinder cylinder rod one end be respectively hinged on the jointed shaft in the middle part of two link assemblies.
As further preferably, each connecting rod of described two link assemblies respectively by two layers of connecting plate by being located at centre
Link of boards forms.
As further preferably, each teeth on described serrated cutting edge are half cone-shaped.
As further preferably, the material of described serrated cutting edge is Cr12.
As further preferably, the teeth spacing on described serrated cutting edge is 50-80mm.
The beneficial effects of the utility model are:
1, due to grab bucket installing rack be symmetrically arranged on two with two link assemblies being hinged, one end of two link assemblies
Be hinged on grab bucket installing rack top, the other end of two link assemblies be hinged on shell grab bucket upper center at outer rim,
It has been respectively articulated with driving oil cylinder between jointed shaft and grab bucket installing rack in the middle part of two link assemblies, the most rational in infrastructure, drive
Cylinder efficient is laborsaving, it is possible to make to grab coal time saving and energy saving, improves work efficiency.
2, owing to being respectively equipped with on serrated cutting edge, and two shell grab buckets in the relative lower edge of two shell grab buckets
Serrated cutting edge is mutually twisted, and therefore during coal grab work, grab bucket insertion coal seam ratio is relatively labor-saving, can not only improve work efficiency,
Avoid material leakage, and the service life driving oil cylinder can be extended.
Accompanying drawing explanation
Fig. 1 is this utility model shell grab bucket structural representation when opening.
Fig. 2 is structural representation during this utility model shell grab bucket Guan Bi.
Fig. 3 is the A-A sectional view of Fig. 2.
In figure: two link assemblies 1, installing rack 2 of grabbing bucket, hinged seat 3, flap seat 4, jointed shaft 5, serrated cutting edge 6, rotating shaft 7,
Shell grab bucket 8, drives oil cylinder 9.
Detailed description of the invention
As shown in FIG. 1 to 3, a kind of coal grab described in the utility model novel grab bucket mechanism, including grab bucket installing rack
2, it is fixed with the flap seat 4 for connecting coal grab support arm in the upper end of grab bucket installing rack 2, in grab bucket installing rack 2 lower end by turning
Axle 7 symmetry is hinged with two shells grab bucket 8, is symmetrically arranged on two with, at grab bucket installing rack 2, two link assemblies 1 being hinged,
One end of two link assemblies 1 passes through the hinge top at grab bucket installing rack 2 respectively, and the other end of two link assemblies 1 is respectively
By hinge in the upper center of shell grab bucket 8 at outer rim, grab in the grab bucket both sides, top of installing rack 2 and shell
The upper center of bucket 8 is respectively welded hinged seat 3 at outer rim.Each connecting rod of described two link assemblies 1 is by two respectively
Individual connecting plate is welded by being located at the gusset of centre.
Jointed shaft in the middle part of two link assemblies 1 and be respectively articulated with driving oil cylinder 9 between grab bucket installing rack 2, described in drive
Cylinder body one end of dynamic oil cylinder 9 is respectively hinged in the rotating shaft between grab bucket installing rack 2 and shell grab bucket 8, drives the cylinder rod of oil cylinder 9
