Abstract
The invention discloses a buffering device, and particularly discloses a breakage-proof buffering device for lump coal. The breakage-proof buffering device comprises a supporting seat, wherein a head shield is arranged on the supporting seat; a chute which is oblique downwards is formed below the head shield; and the chute is a circular-arc curved chute. The chute is the circular-arc curved chute, so that sufficient centrifugal force is generated by the lump coal through acceleration, and the lump coal can perform set curvilinear motion in a buffering device; meanwhile, a centripetal acceleration is generated under the action of composite force, so that the direction of the lump coal is changed, the friction surface of the lump coal along the buffering device is transferred, a free-fall motion is changed into a specific curvilinear motion, the moving speed of the lump coal is lowered greatly, and the collision time of particles is prolonged; and meanwhile, in a process when particles become static from moving, a tangential-velocity component is generated, full non-elastic collision is avoided, and the lump coal is effectively prevented from being broken.

Technical field
The present invention relates to a kind of shock absorber, particularly relate to a kind of lump coal crushing preventing shock absorber.
Background technology
Lump coal breaking is the change procedure of the material piece size of a complexity, and is relevant with many factors.The principal element that affects lump coal breaking has: lump coal is resisted dynamics, intensity, hardness, toughness, shape, size, humidity, temperature, density and equal homogeneity, and outside condition, interacts and distribution etc. in broken moment such as material piece group.
Above-mentioned factor has all caused the complicated of lump coal breaking process, thereby not yet draw so far unified and complete theory and set forth and and guide lump coal breakage-proof practice, fragmentation must have external force that material is done work, just occur when overcoming the binding force of its particle, the size of binding force also is very greatly different to same material, binding force can be divided into two classes: a class is the power between each particle of crystals, another kind of is power between crystal and the crystal, both have identical physical property, but numerical value is different, first kind binding force is than much larger times of Equations of The Second Kind binding force, the size of binding force, depend on the material piece in character and the structure of crystal itself, also relevant with the defective that exists in the structure, these defectives may be the damaging cracks of both macro and micro, and it makes the contact limit between the crystal weak, according to the character that acts between the structure of crystal and particle, can calculate theoretically the binding force between the crystal; As for the size of binding force between crystal, and the caused impact of factor of all reduction material impregnabilityes, still can not accurate Calculation.
According to above principle, lump coal is because of before being subjected to the External Force Acting fragmentation, at first produce elastic deformation, when distortion reached certain value, the fault location of material made up again, and concurrent stiffization and stress increase, external force continues to do the time spent distortion and also continues, until disconnect along the most fragile face, to observe and destroy section as can be known, material ruptures under both combineds action by perpendicular stress pressure break (or drawing crack) with it or producing under the friction stress effect to slide.
Shock absorber of the prior art; chute design is that floor type is obliquely installed; lump coal is along in the operational process of floor; its running orbit and floor coincide; its lump coal stressed is that the gravity of friction force, lump coal self on lump coal and floor and floor are to the bearing force of lump coal; lump coal is stressed to be directly proportional with its kinematic velocity; be inversely proportional to collision time; the downward speed of lump coal is the acceleration/accel of three power generation and the stack of rate of onset; this mode is in weight with in the moment of lump coal reprinting and coal breakage, and the collision of generation still often can cause the fragmentation of lump coal.
Summary of the invention
Lump coal crushing preventing shock absorber of the present invention has overcome the deficiency that prior art exists, and a kind of lump coal crushing preventing shock absorber that can effectively prevent lump coal fragmentation in dropping process is provided.
