As above-mentioned elastic body, there is no particular limitation, for example can list buna-S, government rubber, buttress rubber, poly-chloroprene rubber etc., and therein, particularly the mechanical strength of government rubber and poly-chloroprene rubber is good, so more satisfactory.

In in above-mentioned elastic body at least 1 and the dictyosome described later, form and insert the inserting hole that leads to extension bar, this pipe link is used for transferring vibrations to dictyosome from vibrator.

Though also be formed for inserting the open-work that leads to extension bar at the wall of hopper, this open-work is in order to ensure the freedom that connects vibration of bar, forms than pipe link external diameter and its amplitude and big diameter.

The elastic body of being located at above-mentioned inserting hole covers above-mentioned open-work ground and forms, and above-mentioned dictyosome is connected to fastening state with elastic body and inserts the above-mentioned pipe link that leads in these inserting holes.

, bury ring stiffener underground here around above-mentioned elastomeric inserting hole, this ring stiffener is used to prevent the distortion of this inserting hole, prevent from spilling the material in the hopper between elastic body and the pipe link, and, the elastomeric life-span prolonged, simultaneously, carry out the location of pipe link often.

This ring stiffener is mainly formed by metal, but as this metallic material, can use alloy material such as single metal material such as iron, nickel, cobalt or corrosion-resistant steel, 13 chromium steel and carry out metallic material arbitrarily such as electroplated metal material.

The maximum of taking the anti-locking apparatus of doming effect of hopper of the present invention is characterised in that, above-mentioned dictyosome use metal sheet or synthetic resin board form through hole and make hole pattern arranged, like this, can solve the variety of issue of the occasion of using above-mentioned metal gauze, and can improve dictyosome intensity to heavens, significantly reduce adhering to of powder body, reach desired purpose.

The shape that is disposed at the dictyosome in the hopper can be parallel with the wall shape of hopper or parallel substantially tabular, but be easy to be suspended to the powder body of dictyosome for fibrous powder body etc., be preferably formed as to having the circle parallel or the shape of cartouche with the wall shape of hopper.

The material of dictyosome is not limited especially, specifically, for example can use the metal sheets that resistance to chemical reagents, thermal life, wholesomeness etc. are good and mechanical strength is good such as stainless steel sheet and synthetic resin board etc., this metal sheet and synthetic resin board comprise milled sheet, are provided porous scutum, and the web plate that formed by grid etc. etc. in a plurality of holes by punching press etc., particularly the powder body porous scutum that is difficult for adhering to is better, the porous scutum that particularly provides a plurality of holes of circular and ellipse etc. does not have the angle, the powder body more is difficult for adhering to, cleaning is easy, so more satisfactory.

Taking in the anti-locking apparatus of doming effect of hopper of the present invention, as long as vibrator can make the dictyosome vibration, then be not particularly limited, for its mode of vibration, dictyosome is constituted quiveringly towards the direction along perisporium, or carry out linear vibration ground towards the axle center of perisporium and constitute, or each dictyosome is shaken towards the axle center of perisporium quiveringly constitute.

The preferred implementing form of taking the anti-locking apparatus of doming effect as hopper of the present invention, at first, wall at hopper is provided with the slotting open-work that leads to extension bar, cover this open-work ground configuration elastic body, form each inserting hole of inserting logical above-mentioned pipe link respectively at this elastic body and dictyosome, above-mentioned dictyosome is connected to fastening shape with this elastic body and inserts the above-mentioned pipe link that leads in these inserting holes, around this elastomeric inserting hole, can list and bury the example of location underground, can position pipe link and dictyosome securely by this ring stiffener with ring stiffener.

; method to set up as vibrator; one end that can list this vibrator is connected to dictyosome by above-mentioned pipe link; the other end is supported on the method for hopper by the stay outside the wall body that is welded in hopper; but occasion in the wall body outside that like this stay is welded in hopper; behind the position of the wall body outside of determining stay is welded in hopper; weld by interim in this position of determining; the method of interim bonding grade temporarily anchors to the position that this is determined with the base end part of stay; after this; the fixed order that is welded in the wall body outside of hopper by the base end part with stay arrives hopper; so, need a lot of times and time for stay being fixed in hopper.

Particularly before interim welding, need the pre-prepd occasions such as groove processing, grinding and cleaning of weld part, need more time and time.

In addition, the determining of the installation site of stay, stay may be applied excessive power by the elastic body of vibration between the wall body that is in metal gauze and hopper of vibrator and make the elastomeric lost of life or generation abnormal noise at the easy step-down of precision of the so-called centering operations such as location of the installation site of determining.

In addition,, the material identical need be selected, the stay of the material of aluminum alloy, corrosion-resistant steel geometric ratio iron and carbon steel costliness must be used sometimes with the wall body of hopper as the material of stay for wall body and the stay that welds hopper.

Therefore, take in the anti-locking apparatus of doming effect, an end of vibrator be connected to dictyosome, the other end is supported on hopper by stay of the present invention, in this occasion, preferably clamp 1 to a plurality of elastic bodys with above-mentioned stay with bolt in the wall body of hopper.

Say that in more detail " stay clamp 1 to a plurality of elastic bodys ground with the wall body of bolt to hopper " refers to that the part of stay overlaps with an elastomeric part at least, bolt is inserted the inserting hole that leads to a plurality of bolts that are formed at stay and elastomeric intersection respectively, stay and elastic body are fastened to together the wall body of hopper by these a plurality of bolts, as these a plurality of bolts, comprise insert from the outside of stay lead to be formed at stay and elastomeric bolt insertion hole and screw joint to the bolt (being screwed into bolt) of the tapped bore of the wall body that is formed at hopper with plant wall body outwardly in hopper, insert the elastic body that forms bolt insertion hole and stay from the outside of wall body and from the bolt (implantation bolt) of the outside screw joint nut of stay.

The operation of using a plurality of bolts that stay and elastic body are fastened to the wall body of hopper does not together like this use bonding machine etc. to need skilled device, use the such simple tools of spanner can carry out simply in the time shorter than the operation that stay is welded in wall body, in addition, as the bolt operation carrying out, then stay correctly is positioned at ground, installation site and is fixed in wall body.That is, can compare the centering simply and correctly of short time with the occasion of welding stay, stay is being fixed in the wall body of hopper.

In addition, because stay clamps elastic body ground by the wall body of bolt in hopper, so, do not need to make wall body identical, and wall body and stay direct contact not with the material of stay, so, the material of stay can irrespectively be selected with the material of wall body.

Specifically, for example when wall body contact iron and carbon steel, even the occasion that constitutes at the aluminum alloy by so-called generation electrocorrosion also can be selected to use than the inexpensive iron of aluminum alloy and the carbon steel material as stay.The wall body that also is made of this stainless steel sheet in addition, in the hopper of handling food material, pharmaceuticals, chemical raw material etc., how to form wall body, even but also can use the stay of inexpensive iron and carbon element steel without any obstacle ground by stainless steel sheet.

Shape as above-mentioned stay, can clamp elastic body uses bolt in the wall body of hopper, and, as long as then there is no particular limitation for the shape of the other end of the vibrator that an end can be connected to metal gauze, for example can sheet material be flexed into the L font by compression machine, simultaneously be formed for being fixed to a plurality of bolt insertion holes of wall body at it, but forming the tapped bore that screw joint is inserted in the bolt spiral advance and retreat ground of the other end of vibrator spiral with the rectangular another side of this one side.

; the general vibrator that uses is owing to be provided with the coil spring of the vibration that is used for the transmitting vibrations device therein; so; the vibration that is accompanied by vibrator produces reversing around the axle center parallel with the direction of vibration of vibrator at coil spring; this reverses and is delivered to dictyosome, produces the phenomenon that makes that dictyosome disperses and vibrates towards the direction of vibration of vibrator.

In addition, by this dictyosome discrete make dictyosome about the end and the interval of the wall of hopper produce bigger change, the powder body pressurized that clips betwixt and luming can increase the resistance of vibration of the above-below direction of relative dictyosome.

Like this, the vibrational energy of vibrator is invalidly consumed, and can not eliminate effectively and take doming effect, in addition, takes doming effect in order positively to eliminate, and uses the big large-scale vibrator of horsepower output, and integral body becomes large-scale, and has the problem of cost of equipment costliness.

In addition, because the interval that need increase the wall of dictyosome and hopper to a certain extent prevents that the wall of dictyosome and hopper from colliding, so, can not directly take the more effective hopper wall of arch powder body nearby and apply vibration elimination, unfavorable to raising the efficiency.

Therefore, take in the anti-locking apparatus of doming effect of the present invention, wall at hopper is provided with 1 pair of open-work, on 1 pair of elastic body of inaccessible these open-works, support the dictyosome that is disposed in the hopper by axle respectively, simultaneously, the direction of vibration both ends that are disposed at the outer vibrator of hopper are directly connected to this 1 pair of axle, and this is desirable especially.

Like this, the vibration of vibrator is not passed through spring and direct connection, and the direction of vibration both ends of vibrator are directly connected to axle, so, do not produce the motion of the direction of its direction of vibration intersection relatively at vibrator.Like this, the direction motion that the diaxon that is connected in vibrator does not intersect at direction of vibration relatively, only with the Motion Transmission of the direction of vibration of vibrator to dictyosome.

Therefore, dictyosome can not reverse around the axle center parallel with the direction of vibration of vibrator, powder body between the wall of dictyosome and hopper is oppressed, and the possibility of the resistance of the vibration of the above-below direction of dictyosome increase disappears the generation that can be prevented to take arch by less power effectively relatively.

In addition, the possibility that dictyosome reverses around the axle center parallel with the direction of vibration of vibrator disappears, the result, can reduce the interval of the wall of dictyosome and hopper, take in elimination and to encircle actv. hopper wall and nearby make the dictyosome vibration, can improve and take arch elimination effect, result, the generation that can further prevent to take arch effectively by littler power.

In addition, owing to do not use the spring of the deviation that is easy to produce scale error and elastic force etc., so the normalisation of parts is easy, by making each parts in a large number by batch manufacturing, but cost-cutting.

In this occasion, the shape of open-work that is formed at the wall of hopper does not limit especially, but is circle in order not apply the directivity of intensity at wall, to be preferably formed as.In addition, the interval of these open-works can be corresponding to the length decision of vibrator along direction of vibration.

In addition,, simultaneously, be out of shape around making open-work, tension member preferably is set in order to prevent vibration in the weight that the anti-locking apparatus of doming effect is taken in the circumference supporting of this open-work.Certainly, this tension member preferably is arranged at the wall outside of hopper for the flatness of the wall inner face that do not damage hopper.

The elastomeric shape of inaccessible above-mentioned open-work and big I become cover open-work and complete around size and shape, but in order to increase the amplitude of dictyosome towards the direction of vibration of vibrator, be preferably formed as the lid shape of protruding for towards the inboard of hopper, in addition, the oral-lateral that is preferably in this lid shape is connected with outward flange so that reliable and can improve inaccessible air-tightness in the installation of the wall of hopper.

In addition, dictyosome supports to 1 pair of elastic body of inaccessible open-work respectively by axle, but as supporting construction, for example can list such example, that is, using has the head axle as this axle, should axle insert and lead to dictyosome, simultaneously, by this head and elastic body clamping dictyosome, maybe will there be head or axle without a head to be welded in dictyosome.

The formation that is disposed at the outer vibrator of hopper is not particularly limited as long as constitute quiveringly towards certain direction of vibration, for example can use over known various vibrator.Yet, in these known vibrators, preferably use small-sized but strength is big and amplitude is big shakes type cylinder (rocking frame).

This shake the type cylinder have the cylinder at sealing two ends, slidably be inserted into piston in the cylinder, moving contact airtightly in the flange of the periphery of the pars intermedia of this piston, between the cylinder of these flange both sides and the piston along the inlet that forms in full week be separated in the downstream chamber, in cylinder the piston both sides 1 pair of compression chamber, and be connected switching channel, this connection switching channel is formed in the piston and the compression chamber of this end side is connected from the downstream chamber in the end of travel of piston and switches to inlet, from inlet the compression chamber of opposite ends side is connected to switch to the downstream chamber; When supplying with forced air equipressure fluid to inlet and being communicated to the downstream chamber in the atmosphere by for example noise silencer etc., piston is crank motion in cylinder, simultaneously, the interior pressure of both sides' compression chamber alternately switched to supply with press and barometric pressure, cylinder is towards its axis direction vibration.

And, shake the cylinder of type according to this, do not make the rotating such power of cylinder owing to do not produce, so axle and dictyosome are reversed.

In this vibrator, be connected with earrings by two ends at cylinder, can be connected simply with being connected to dictyosome and being supported on elastomeric axle.For example, lead to the hole of earrings, and fastening screw joint is in the nut of the end of axle, thereby can simply vibrator be directly connected to axle by the end of axle is inserted.In this occasion, as for example using fly nut etc. as nut, then serviceable tool can not carry out the mounting or dismounting of vibrator by relative simply axle.

The formation that vibrator is directly connected to axle is not limited thereto example, for example also can not vibrator be directly connected to axle by welding, bonding, riveted joint etc. with decomposing, but the material appearance miniaturization when carrying in order to make, save and carry cost, and improve the comfort feature of the maintenance of part replacement etc., use nut as described above, or use bolt, can directly vibrator be connected to axle with decomposing, then better.

Below, describe powder supply device of the present invention in detail.

Powder supply device of the present invention is characterised in that: the doming effect of taking that is provided with the invention described above at hopper is prevented locking apparatus.

Promptly, powder supply device of the present invention mainly comprises device body, dictyosome, reaches vibrator, this device body has the hopper that forms the tiny taper in bottom, this dictyosome along the inside wall configuration of this hopper and elastic support in above-mentioned hopper, this vibrator makes this dictyosome vibration, by such formation, do not produce the doming effect of taking of powder body, can successfully discharge the powder body from hopper.

Yet, in powder supply device of the present invention, when having 1 dictyosome and make 1 vibrator of this dictyosome vibration, the dictyosome that is driven by vibrator is 1, can not apply the different vibration of direction to the powder body overlappingly, like this, it is a lot of that the pseudodensity of powder body is improved, so, for the pseudodensity that improves the powder body very time-consuming, according to the difference of powder body, the occasion that can not realize desired raising pseudodensity is arranged also.

In this occasion, particularly the degree of compression Gao Shike when material powder sees effect, but when the degree of compression of material powder hanged down, the raising of the pseudodensity of powder body was very time-consuming, according to the situation of powder body, also has the occasion that can not realize desired raising pseudodensity.

Therefore, in the present invention, at 1 hopper a plurality of the present invention are set and take the anti-locking apparatus of doming effect ideal especially, like this, can apply the different vibration of direction at the powder body overlappingly, the result can be in the pseudodensity of extremely short time raising powder body.
