Abstract
The utility model provides an arch-breaking machine for a coal bunker. The machine comprises an arch-breaking shaft which is arranged on the lower portion of the side wall of the coal bunker and perpendicular to the side wall of the coal bunker, and is in a transmission connection with a power drive device. The machine is characterized in that a screw blade is arranged on the arch-breaking shaft, the diameter of the screw blade increases gradually along the extending direction of the arch-breaking shaft, and the proportion of the largest diameter to the smallest diameter of the screw blade is (1.2-1.3):1. The arch-breaking machine for the coal bunker has the advantages of being good in arch-breaking effect, safe and efficient and low in noise.
Description
Technical field
The utility model relates to a kind of Arch-Breaking Device, particularly is applicable to the mechanical Arch-Breaking Device of coal bunker.
Background technology
Coal bunker is an imperative equipment during a lot of industrial enterprise produce, and mostly the profile of coal bunker is top cylinder shape, lower taper structure, and this structure is easy to the material handling of powder agglomates shape, has obtained widespread use.But the coal bunker of this structure is easily because the easy arch camber of friction force, the obstruction of material, and vertical bulkhead and broach hopper joint portion are the positions of the easiest arch camber.For the problem that solves arch camber generally adopts the broken arch technology of vibrations, promptly use machinery or air bubble to produce vibrations, make material loosening, can continue gravity fall.The broken arch of sand, stone material effect is better preferably for flowing power for this method; But poor to flowing power, moist powder agglomates shape material such as fine coal; Its broken arch effect is very undesirable, thereby it is not smooth to cause material to flow, and in practice of construction, often needs artificial broken arch; Inefficiency not only, and influenced routine.Another shortcoming of the broken arch technology of vibrations is that noise is big.
The utility model content
The purpose of the utility model be to overcome the broken arch of vibrations technique effect poor, need artificial auxiliary broken arch and the big weak point of noise, provide that a kind of broken arch is effective, safe and efficient, the coal bunker Arch-Breaking Device of low noise.
The purpose of the utility model reaches through following technical measures:
A kind of coal bunker Arch-Breaking Device comprises the broken arch axis that is installed on the coal bunker sidewall, and broken arch axis is connected with Power Drive Unit, it is characterized in that: said broken arch axis is provided with helicallobe.
Say that further the radius of said helicallobe increases along broken arch axis bearing of trend gradually.
Say that further the ratio of said helicallobe maximum radius and minimum radius is 1.2～1.3: 1.
Say that further said broken arch axis is positioned at the bottom of coal bunker sidewall.
Say that further said broken arch axis is vertical with the coal bunker sidewall.
Owing to adopted technique scheme, compared with prior art, the utility model has the advantages that:
(1) broken arch is effective;
(2) safe and efficient;
(3) low noise.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
Description of drawings
Accompanying drawing is the structural representation of a kind of coal bunker Arch-Breaking Device of the utility model.
The specific embodiment
Embodiment: shown in accompanying drawing, a kind of coal bunker Arch-Breaking Device comprises the broken arch axis 5 on the tapered portion sidewall 4 that is installed in coal bunker 3 lower ends, and broken arch axis 5 is connected with Power Drive Unit 6, and broken arch axis 5 is provided with helicallobe 1.The radius of helicallobe 1 increases along broken arch axis 5 bearing of trends gradually.Particularly; Difference according to bunkering capacity; The ratio of helicallobe 1 maximum radius and minimum radius changes accordingly, and for 20 tons to 50 tons coal bunkers, the typical proportions of helicallobe 1 maximum radius and minimum radius is 1.2～1.3: 1; To less than 20 tons corresponding being reduced to below 1.2: 1 of this ratio of coal bunker, can increase to more than 1.3: 1 coal bunker greater than 50 tons.
In the present embodiment, the lower end of coal bunker 3 has a tapered portion, the coal bunker tapered portion be provided with discharging opening 2 bottom, broken arch axis 5 is positioned at the bottom of coal bunker 3 tapered portion sidewalls 4, broken arch axis 5 is vertical with coal bunker 3 tapered portion sidewalls 4.
This coal bunker Arch-Breaking Device that the utility model provides has the broken advantage effective, safe and efficient, low noise of encircleing.
