Summary of the invention
The purpose of this utility model provides the defeated exchange device of a kind of material bin blanking, and this device adopts the combination of preventing and treating of conveying and mediation, to solve the problem of material bin blanking putty.
For solving the problems of the technologies described above, the utility model provides a kind of material bin blanking to fail exchange device, and this device comprises the driving device that is positioned at material bin in-to-in material guide device and is installed in the outside side of material bin, wherein:
Material guide device comprises center baffle and control flap, triangular in shape or two sides, the vertical section of center baffle are the fleetline triangular shape, a center baffle coupling spindle is to be fixed on the baffle of center perpendicular to the vertical section direction, the two ends of described center baffle coupling spindle and the warehouse of material bin are hinged, below the baffle of center, inclined-plane along the center baffle is symmetrically installed with 2 control flaps, and described control flap is movably arranged on the material bin by the control flap coupling spindle of end fixed thereon;
Driving device is by the active fork, the transmission fork, the control bull stick, adjustable spring Connection Block and self aligning spring are formed, 2 control flap coupling spindles be positioned at the exterior side of material bin be fixed with respectively 2 with described control flap control bull stick in the same way, be provided with an adjustable spring Connection Block between 2 control bull sticks, described adjustable spring Connection Block links together by 2 self aligning springs and 2 control bull sticks, the transmission fork is movably connected in material bin warehouse outside by transmission fork anchor shaft, captive joint with the adjustable spring Connection Block in its lower end, with initiatively fork is hinged, initiatively the upper end of fork is fixedly mounted on and is positioned on the baffle coupling spindle of the exterior center of material bin by the fork trundle in the upper end.
Further, the defeated exchange device of material bin blanking of the present utility model also includes and is installed in the exterior oscillatory system of material bin, described oscillatory system by vibrator, pass shake spring and biography and shake and be configured to, the biography support that shakes is fixedly mounted on and is positioned on the baffle coupling spindle of the exterior center of material bin, and vibrator is connected by biography spring and the biography support that shakes that shakes.
And then the defeated exchange device of material bin blanking of the present utility model can also respectively be provided with a limiting stopper in the both sides of active fork, and described limiting stopper is fixed on the outside of material bin warehouse.
After adopting the defeated exchange device of material bin blanking of the present utility model, when material drops to the bottom discharge mouth from material bin top, the space that will surround through center baffle, control flap and material bin successively, the weight major part of material is by the support of making a concerted effort of center baffle, control flap and material bin wall.Because center baffle and control flap have been born the weight of material greatly, making that the material bin wall of its underpart is stressed reduces greatly, thereby reduced to arrive under the control flap friction force of discharging opening partial material and material bin wall greatly, avoided near the blanking of discharging opening to stop up.
Baffle residing position in center is higher, makes that the wall spacing of itself and material bin is relatively large, has reduced the probability that material knot arch stops up; The residing position of control flap is lower, makes that its wall spacing with material bin is relative less, and the weight of material that bears is also more, and corresponding material knot arch probability increases.When the knot arch takes place in this position, control flap pressure increases, by control flap coupling spindle and the control bull stick that connects with it, power is passed to the self aligning spring, make the self aligning length of spring compressed, the control flap rotates thereupon, and the support force system in equilibrium of material knot arch is destroyed, cross-sectional flow area increases, and the material by gravity falls.Otherwise when the material whereabouts was more smooth and easy, control flap pressure reduced, upwards rotate thereupon, reduced the cross-sectional flow area that material falls, born more material gravity, alleviate the friction force of center baffle and material, reduced the material knot arch probability at baffle position, center.
On the other hand, when the control flap swings up and down, power is passed to the transmission fork that links by the adjustable spring Connection Block that connects with the self aligning spring, make the transmission fork around the swing of transmission fork anchor shaft, the top of transmission fork passes to initiatively fork by the fork trundle with power, initiatively fork passes to the center baffle by the center baffle coupling spindle that connects successively with power again, causes the swing of center baffle.Like this can be so that the center baffle often is in active state, increased the dynamic friction of itself and material, reduced static friction, friction force greatly reduces, thereby reduces the probability that finishes arch.
Find out thus, potential energy and the kinetic energy of the utility model by utilizing material, automatic compensation is to the bearing force and the state of material, thereby adjust friction force with material, the blanking of guaranteeing material is unobstructed, thereby the defeated exchange device of material bin blanking of the present utility model has the function of automatic transport material.
When material rerum natura variation, the probability of knot arch putty increases.When having detected the fracture signal in the material bin and send, this signal can Vibration on Start-up device, and the control vibrator produces disturbance force, successively by joining biography shake spring, pass the support that shakes and give center baffle coupling spindle and center baffle the vibration wave transfer of energy; Center baffle coupling spindle is also transferred to the transmission fork by joining active fork, fork trundle with a part of vibration wave energy simultaneously successively, make the transmission fork around transmission fork anchor shaft swing vibration, again by this partial vibration wave energy being transferred to the control flap, it is vibrated at last with the joining successively adjustable spring Connection Block of transmission fork, self aligning spring, control bull stick and control flap coupling spindle.In addition, because the position-limiting action of limiting stopper, when vibrational energy is very big, initiatively fork will strike the limiting stopper of both sides, thereby the partial vibration wave energy is transferred on the material bin that links with limiting stopper again, cause the vibration of material bin simultaneously.Above vibrational energy all makes material reduce and surface-supported friction force, and the vibration wave transfer of energy has also destroyed the force balance of material knot arch power system, thereby the material by gravity is flowed downward to material.
Find out that thus the utility model can also pass through the external vibration wave energy, reduce the friction force of material support system, guarantee that the blanking of material is unobstructed, thereby the defeated exchange device of material bin blanking of the present utility model is with the function of passive mediation material.
Adopt material bin blanking of the present utility model to fail exchange device, the external force vibration of its use is different from traditional approach.Traditional approach is that external force is directly acted on the material bin, and in order to be effective, energy charge is bigger, not only causes device damage easily, and deals with that material is pushed is more closely knit improperly, more difficult mediation.External force vibration of the present utility model then mainly directly acts on material inside, and the inside mutual action force balance of knot arch centre material is least stable, only needs less energy just can destroy its balance.Have only sub-fraction external force and energy to directly act on material bin, to reduce the friction force of limit wall, its amplitude is less, and damage can not impact to the equipment that connects.Because the utility model is at first the material centre to be dredged, thereby it is closely knit that external vibration also can not make material push, so preventing plug dredging effect of the present utility model is better.
The tight power of self aligning spring when the defeated exchange device of material bin blanking of the present utility model can come the instrumentality feed bin to fill material by the length of adjusting the adjustable spring Connection Block, thereby change the corner of control flap, then change the stressed distribution of control flap and center baffle, to adapt to the material of different rerum naturas, make defeated exchange device remain best mode of operation.
