A material is released into the buffer device through the material charging pipe, and is scattered to a storage silo at a low speed after being buffered by the conical buffer; and the buffer mechanism realizes repeated buffer and recovery under the combined action of the buffer spring and the material.
Description
Technical field
The present invention relates to a kind of suspension-type solid material vertically throw in buffer unit, especially one and be applicable to colliery and gold
Belong to mine solid filling coal mining solid material and be vertically thrown to the buffer unit of down-hole by ground.
Background technology
At present, solid filling coal-mining technique has been realized in the scale exploitation to " three times " pressure coal, greatly increases
The recovery ratio of coal, it is achieved that the control to earth's surface, solves the accumulation problem of earth's surface spoil the like waste.Adopt at solid filling
In coal feeding system, general spoil is thrown to shaft bottom by ground, and the spoil fallen at a high speed has greatly impulsive force, if be not added with
With buffering, the facilities such as down-hole storage bin can be caused greatly destruction, cause huge economic loss, have a strong impact on the normal of mine
Produce.
Summary of the invention
Technical problem: it is an object of the invention to the weak point overcome in prior art, it is provided that a kind of simple in construction, safety
Efficiently, low cost, the suspension-type solid material vertical feeding buffer unit of falling material impulsive force can be effectively reduced.
Technical scheme: the suspension-type solid material vertical feeding buffer unit of the present invention, mainly by buffer gear and spacing
Mechanism's two parts composition, described buffer gear includes taper buffer, buffering plate and buffer spring, described position-limit mechanism
Including upper limit nut, lower position nut and guide rail, taper buffer is fixed on buffering plate, and buffering plate is socketed with guide rail
Connect, buffer spring upper end is connected with buffering plate, and buffer spring lower end is fixed on lower position nut, upper limit nut with under
Stop nut is connected with guide rail respectively and fixes, and guide rail upper end is fixedly welded on commissioning pipe outer wall, and guide rail lower end is provided with an opening
Pin is fixed.
Described taper buffer radius R1With commissioning pipe internal diameter R2Ratio need to meet: R1/R2=1.1～1.3.
Described taper buffer surface is coated with abrasion-resistant stee.
Beneficial effect: owing to have employed technique scheme, when material is thrown to buffer unit through commissioning pipe by ground, thing
Most of kinetic energy of material is converted into the elastic potential energy of buffer spring, thus achieves safely and effectively delaying high speed falling material
Punching, buffer unit recovers to original state with the release of buffer spring elastic potential energy.Whole apparatus structure is simple, user
Just, safe and efficient, small investment, at well work filling mining, there is wide applicability, the mine engineering for other has reference
Meaning.

Detailed description of the invention
Below in conjunction with the accompanying drawings one embodiment of the present of invention is further described:
The suspension-type solid material vertical feeding buffer unit of the present invention, it is mainly by buffer gear and position-limit mechanism two
Being grouped into, described buffer gear includes taper buffer 1, buffering plate 2 and buffer spring 3, and described position-limit mechanism includes
Upper limit nut 5, lower position nut 6 and guide rail 4, taper buffer 1 is fixed on buffering plate 2, taper buffer 1 radius R1
With commissioning pipe 8 internal diameter R2Ratio need to meet: R1/R2=1.1～1.3；Buffering plate 2 is connected, on buffer spring with guide rail 4 socket
End 3 is connected with buffering plate 2, and buffer spring 1 lower end is fixed on lower position nut 6, upper limit nut 5 and lower position nut 6
Being connected with guide rail 4 respectively and fix, guide rail 4 upper end is fixedly welded on commissioning pipe 8 outer wall, and guide rail 4 lower end is provided with a split pin 7 and adds
With fixing；Taper buffer 1 surface is coated with AM360 type high-strength abrasion-proof steel.
During work, ground material is thrown to suspension type vertical through commissioning pipe and feeds intake buffer unit, and taper buffer 1 is arrived
After the impulsive force of material, and buffering plate 2 entirety is along guide rail 4 slide downward, material after taper buffer 1 buffers, low speed
It is scattered to storage bin；Now, buffer spring 3 is compressed, and has an active force upwards to buffering plate 2, thus delays taper
Rush device 1 and cushioning effect power upwards is provided.At the end of feeding intake, taper buffer 1 and buffering plate 2 are in the lump at buffer spring 3
Effect is lower restores to naturalness.This buffering course is carried out with the blanking circulation that goes round and begins again, thus continually to the thing launched
Material buffers.This suspension-type solid material vertical feeding buffer unit reduces the impulsive force of material, reduces storage bin
Destruction, it is achieved that the safety of material is thrown in.
