Technical field
The invention belongs to waste bin protective device technical fields, and in particular to a kind of spoil feeds intake the underground buffering dress of well
It sets.
Background technique
With the fast development of coal industry, more and more coal enterprise are opened using gangue and flyash backfill coal mine
Post-job goaf is adopted, is filled in this way using the solid waste that coal mine generates, has not only been eliminated hillock and protected
Arable land, but also environment is protected, there is great meaning to the sustainable development of coal industry.
It is easy agglomeration when due to gangue and flyash long-time mixed-stacking and causes stifled storehouse, downhole gangue storehouse is every
It has to bring down stocks after secondary filling.It, can be to waste bin storehouse when gangue and flyash in the prior art are launched from ground to underground
Wall or fore shaft are hit, and wash away spoil silo wall for a long time and fore shaft be easy to cause the damage of waste bin.
Summary of the invention
Place in order to overcome the above-mentioned deficiencies of the prior art, the present invention provide the underground buffering dress that a kind of spoil feeds intake well
It sets, impact of the gangue to downhole gangue storehouse can be effectively reduced.
The present invention is achieved through the following technical solutions: a kind of spoil feeds intake the down-hole buffering mechanism of well, including buffering
Device, spring support and support beam, spring support include upper bracket plate and lower bracket plate, and the support beam is fixed on spoil
On the side wall in storehouse, the lower bracket plate of spring support is fixedly connected with support beam, and spring support is equipped with several elastic devices, elasticity
Device is equipped with upper bracket plate, and buffer is mounted on the upper side of upper bracket plate；The downside of upper bracket plate, which is fixedly installed, leads
Xiang Zhu, guide post pass through the lower section for reaching lower bracket plate from the pilot hole on lower bracket plate.
Further, the buffer is bowl shaped structure.
Further, several stiffener plates are equipped between the bowl shaped structure excircle and upper bracket plate of the buffer.
Further, the elastic device is the spring with guide rod, and spring pocket fills on the guide bar, guide rod
Bottom is fixedly connected with lower bracket plate upper side, and upper bracket plate is equipped with mounting hole, and upper bracket plate is sleeved on by mounting hole leads
To on bar.
Further, the support beam is steel I-beam.
The beneficial effects of the present invention are: buffer unit provided herein, is filled by the buffer of bowl shaped structure, elasticity
It sets and support beam, when gangue and/or flyash being made to feed intake, gangue and/or flyash can be effectively reduced to well
The impact of lower waste bin, to reduce the maintenance of waste bin.

Specific embodiment
Below according to drawings and examples, the present invention is further described.
As depicted in figs. 1 and 2, a kind of spoil feeds intake the down-hole buffering mechanism of well, and buffer unit 14 passes through support beam 115
It is fixed in waste bin 15, the both ends of support beam 115 are each attached on the side wall of waste bin 15, the lower bracket of buffer unit 14
Plate 113 is fixedly connected with support beam 115, and support beam 115 is steel I-beam.If lower bracket plate 113 is filled equipped with dry elasticity
116 are set, elastic device 116 is equipped with upper bracket plate 112, and buffer 111 is mounted on the upper side of upper bracket plate 112, elasticity dress
It sets 116 and here functions as the effect for absorbing impact force；The downside of upper bracket plate 112 is fixedly installed guide post 114, guide post
114 pilot hole from lower bracket plate 113 passes through the lower section for reaching lower bracket plate 113.The top of chamber 12 is equipped with and is passed through by outside
Through the waste shaft 11 in waste bin 15, waste shaft 11 is located at the surface of buffer 111.The buffer 111 is bowl-type
Structure.When work, solid waste 13(gangue and/or flyash) it is fallen by waste shaft 11, it drops into buffer 111
And accumulated in buffer 111, solid waste 13 forms solid taper heap after piling with, and it is useless then to fall into solid from waste shaft 11
Gurry 13 changes movement of falling object state under the effect of impact of solid taper heap, reduces during mutual collision effect dynamic
Can, solid waste 13 is finally slipped in waste bin 15.
As the improvement of the present embodiment, it is equipped between the bowl shaped structure excircle and upper bracket plate 112 of buffer 111 several
Stiffener plate 117, stiffener plate 117 are used to reinforce the intensity of 111 overhanging portion of buffer, avoid 111 overhanging portion of buffer
Intensity is weaker, the destruction of generated impact force when being declined by solid waste 13.
As the improvement of the present embodiment, the elastic device 116 is the spring with guide rod, and spring pocket is mounted in guiding
On bar, the bottom of guide rod is fixedly connected with 113 upper side of lower bracket plate, and upper bracket plate 112 is equipped with mounting hole, upper bracket plate
112 are set on the guide bar by mounting hole.When falling into solid waste 13 in buffer 111, buffer 111 can be with
Upper bracket plate 112 carries out axial displacement along the downward holddown spring of guide rod, and the flexible design of buffer unit 14 has buffered solid
The greater impact that waste 13 generates when falling into buffer 111.
Buffer unit is located in waste bin, by the buffer, elastic device and support beam of bowl shaped structure, makes to fall
The gangue and/or flyash entered absorbs kinetic energy by elastic device after contacting with buffer, significantly reduces gangue
And/or impact of the flyash to downhole gangue storehouse, to reduce the maintenance of waste bin.
It is to be illustrated to the better embodiment of the invention above, certainly, the invention can be with
Using form different from the embodiment described above, those skilled in the art are in the premise without prejudice to the inventive spirit of the present invention
Equivalent transformation or corresponding modification made by lower, in the protection scope that all should belong to the invention.
