Description
Technical field
The present invention relates to mobile discharge cleaners, more particularly to cooperate with mobile dummy car, it is fixed for bulk transportation
The dedusting sealing device of point discharging.
Background technique
Belt tripper may be implemented to have obtained in actual production wide in transport path on the way flexible discharging
General application, according to production requirement, dummy car can be along the linear discharging of carry out of any position of transportation route, can also be along defeated
It send approach fixed point fixed-point unloading, to inhibit the fugitive dust in discharge process, adds deduster on usual dump car, however
In fixed-point unloading, dummy car needs move back and forth between multiple emptying points, the mobile discharge chute and blow tank of dummy car
Between move switching sealing fix, be inhibit discharge process in fugitive dust, anti-leak-stopping dirt, the key link leaked out.
The dust pelletizing system of existing mobile dummy car exposes in some structure designs in actual use due to haveing the defects that
A series of problem is gone out.Firstly, inevitably there is certain miss during installation in the absolute altitude in view of mobile dummy car track
Difference, the error are possible to cause mobile discharge slot to collide with fixed blow tank when docking, currently used scheme be
Therebetween reserved certain interval, with the gap come the absolute altitude error of " absorption " track, to guarantee that mobile dummy car can be smooth
It is current, but the structure makes to certainly exist certain gap between fixed butt tube and mobile butt tube, causes the two cannot be real
Now tight docking；Simultaneously as there is error the actual installation position and design parameter of mobile discharge slot and fixed blow tank,
And there is also errors for the position stopped every time of mobile discharge slot and design position, therefore, when mobile discharge slot and fixed blow tank
In docking, certain radial clearance is certainly existed, to reduce the radial clearance must manually adjust mobile discharge by worker
The position of slot, it is troublesome in poeration, influence discharging progress, and manually adjust it is also different surely completely eliminate radial clearance, even if disappearing
In addition to radial clearance, axial gap is still had, and dust pelletizing system sucks a large amount of wild wind in the gap location when this makes discharging, is caused
The biggish pressure loss makes winner's air hose cause dust removing effects bad to the pumping deficiency in draught of mobile discharge slot, seriously affect hilllock
The operating environment of position worker.
Of the existing technology in order to solve the problems, such as, people have carried out long-term exploration, propose miscellaneous solution
Scheme.For example, Chinese patent literature title are as follows: (Publication No. CN 101837898A) discloses a kind of mobile dummy car
Dedusting air hose docking facilities, including being fixed on fixation butt tube in workshop on main air hose and being installed on mobile dummy car
Mobile butt tube, at least one of described two butt tubes are equipped with elastic telescopic section in butt end, and two kinds of butt tubes are logical when docking
It crosses the elastic telescopic section mutually to compress and be in close contact, however in the technical program, the fugitive dust that when discharging generates will be through movement
Butt tube, fixed butt tube and main air hose are sent after absorbing to cleaner, are by mobile butt tube and fixed butt tube
Portion is comprehensively aspirated, and to meet the purpose of dedusting, the dust removal method of this kind of comprehensive drawing-in type, energy consumption is high, and is extremely easy
The lesser particle of particle in discharge process is sucked into cleaner, there are biggish security risk, and the equipment of this kind of dedusting
The discharging of the loose unpacked material of belt conveyor progress can not be applicable in method.
Therefore, this, which is also constituted, requires further improvement for belt conveyor discharging for bulk transportation fixed-point unloading

This should be easy to contemplate for those skilled in the art, therefore this is no longer going to repeat them.
If Fig. 6 to Fig. 9 is the assembly work provided by the present invention for the dedusting sealing device of bulk transportation fixed-point unloading
Schematic illustration, comprising the following steps:
Before dummy car drives mobile discharge chute 10 and fixed material acceptance glide chute 50 to cooperate, in clump weight to 25, pull rod 41
Collective effect under, the bottom edge face of moving slide board 24 but is higher than the bottom in the excessive face of its circular arc lower than the top surface of envelope fixed glides 60
Side；
When dump car continues to move forwards, moving slide board 24 is contacted with fixed glides 60, contacts initial stage, moving slide board
The excessive face of circular arc of 24 bottom end arc surface and fixed glides 60 generates tangential contact and works as shifting as dump car moves forwards
After the center of gravity of dynamic slide plate 24 crosses the arc surface of fixed glides 60, under pressing force effect of the clump weight to 25, moving slide board
24 generate the sliding being in close contact with fixed glides 60；
When dump car continues to move forwards, when the right end of moving slide board 24 is run to the position of the first contact-making switch 71,
Contact probe head is pressed, and circuit is switched on, and excitation discharging vehicle control issues the pre- stop sign that slows down；
When dump car continues to move forwards, when the right end of moving slide board 24 is run to the position of the second contact-making switch 72,
Mobile discharge chute 10 and fixed material acceptance glide chute 60 are completely to just, and the contact probe head of the second touching switch 72 is pressed, and circuit is connect
Logical, dummy car parking, deduster starting starts discharge operation.
