Description
Technical field
Mechanical motor-driven excavation field is the utility model is related to, more particularly to a kind of mechanical motor-driven excavation bucket
Bolt mechanism.
Background technology
Mechanical motor-driven excavation is excavated using the monobucket of the driving member passing powers such as gear, chain, wire rope pulley group
Machine, power shovel is also, is the main extractive equipment of modern various opencuts.Collecting bucket is generally rigidly fixed on dipper, electricity
Dipper bucket structure is in the majority with crowd shovel, saddle bearing is housed among its swing arm, dipper is supported on and can rotated around it, and utilizes tooth
Wheel rack or cable wire are stretched.During operation, using swing arm as supporting, dipper stretches out, by bucket tooth pressure press-in excavation surface, while by
Raising rope lifting bucket is excavated.Bucket bottom has spoon door, and spoon door is closed by bolt mechanism, and spoon door is unloaded when opening
Material.
The information for being disclosed in the background section is merely intended to increase the understanding to general background of the present utility model, and
It is not construed as recognizing or implies that the information structure has been existing well known to persons skilled in the art in any form
Technology.
Utility model content
The purpose of this utility model is to provide a kind of bolt mechanism of mechanical motor-driven excavation bucket, and bolt mechanism is not
It is easily damaged, reduces replacing number, improves production efficiency.
To achieve the above object, the utility model provides a kind of bolt mechanism of mechanical motor-driven excavation bucket, spoon
The bottom of bucket is provided with spoon door, and the back side of spoon door is provided with supporter, and the bolt mechanism includes：Lever, its one end are hinged by rotating shaft
On supporter, the insertion end of rotating shaft is provided with backing pin, and backing pin is the steel wire rope that diameter is not less than 1.5cm, and the other end of lever connects
It is connected to drawstring；And latch, it is connected with the middle part of lever, and when spoon door is closed, the latch is inserted by deadweight insertion bucket bottom
Hole, when spoon door is opened, lever pulls latch to leave jack.
Preferably, one end of steel wire rope is socketed with cap nut, and one end of cap nut and steel wire rope welds together.
Preferably, the other end of steel wire rope has the free end extended.
Compared with prior art, the utility model has the advantages that：By using steel wire rope as backing pin, utilize
Rope anti-bend turns round the advantages of ability is strong, and intensity is high, and can withstand shocks load, and rigidity is not larger flexible, flexible preferable so that
Bolt mechanism is less likely to be damaged, and reduces replacing number, improves production efficiency.
Brief description of the drawings
Fig. 1 is the schematic diagram according to the bolt mechanism of mechanical motor-driven excavation bucket of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
New protection domain is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
As shown in figure 1, the latch according to a kind of mechanical motor-driven excavation bucket of the utility model embodiment
Mechanism, the bottom of bucket are provided with spoon door, and the back side of spoon door is provided with supporter, and the bolt mechanism includes lever 1 and latch, lever
1 one end is hinged on supporter 2 by rotating shaft 21, and the insertion end of rotating shaft 21 is provided with backing pin 22, and backing pin is not less than for diameter
30cm steel wire rope, the other end of lever 1 are connected with drawstring, and backing pin 22 is connected with the middle part of lever 1, and when spoon door is closed, this is inserted
The jack by deadweight insertion bucket bottom is sold, when spoon door is opened, lever 1 pulls latch to leave jack.
As a kind of preferred embodiment, one end of steel wire rope is socketed with cap nut, one end welding of cap nut and steel wire rope
Together.
As a kind of preferred embodiment, the other end of steel wire rope has the free end extended.
In such scheme, the long steel wire rope thick not less than 1.5cm using a diameter borrows steel wire rope in itself as backing pin
With bending resistance, the advantages of being not likely to produce impact shock, it is not easy to be broken.Due to existing backing pin 1.5cm bar reinforcements,
Because spoon door switch frequently shakes, bar reinforcement is often broken, it is necessary to change, and influences operating efficiency, using steel wire rope as backing pin,
It is longer than the reinforcing work time 4~5 times through using effect, reduce and change number, improve production efficiency.
To sum up, the bolt mechanism of the mechanical motor-driven excavation bucket of the present embodiment, by using steel wire rope as backing pin,
The advantages of ability is strong, and intensity is high, and can withstand shocks load, and rigidity is not larger flexible, flexible preferable is turned round using rope anti-bend,
So that bolt mechanism is less likely to be damaged, reduce replacing number, improve production efficiency.
The foregoing description to specific illustrative embodiment of the present utility model is to illustrate and the purpose of illustration.These
Description is not wishing to for the utility model to be defined to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can carry out
It is many to change and change.The purpose of selecting and describing the exemplary embodiment is that explain certain principles of the present utility model
And its practical application, so that those skilled in the art can realize and utilize a variety of examples of the present utility model
Property embodiment and various chooses and changes.The scope of the utility model is intended to by claims and its waits similar shape
Formula is limited.
