。[Detailed description of the invention] The present invention relates to an improvement of a resonant sieve in which two vibrating frames are connected to each other by an elastic body and are vibrated in opposite directions by being given an excitation force by a common drive device. It is something.

る方向に運動するようになっている。As shown in Japanese Patent Application Laid-Open No. 51-90063, this type of device connects two vibrating frames arranged one above the other with an elastic body, and further supports the connected vibrating frames with a common elastic body. The resonant sieve is constructed such that the classifying surfaces formed by the bars of the vibrating frame lie on the same plane, so that the equal classifying surfaces move in opposite directions.

、分級面上の負荷が２個の振動篩共に同一負荷となるの
で振巾の変化は全く影響なく安定した運転が出来るとい
う特徴がある。The resonant sieve has a large impact force on the raw material, which prevents clogging due to material adhesion.Furthermore, since the classification surface is composed of a so-called bar screen with a bar shape, the sieve has a high porosity and is easy to open. Clogging due to low porosity is also prevented, and since the load on the classification surface is the same for both vibrating sieves, changes in the shaking width have no effect and stable operation is possible.
しかしながらバーの形状が直線形状で、しかも互に隣合

為、偏平なサイズのものは原料の流れ方向のスリット規
制がないところから、バーから通過してしまい粒度を荒
くしているという欠点がある。However, since the shape of the bars is linear, and the sorting size is regulated by the spacing between adjacent bars, flat-sized bars have no slit regulation in the flow direction of the raw material. The disadvantage is that it passes through the grains, making the grain size coarse.

その目的とするものである。This project was devised to improve the above-mentioned drawbacks, and it is difficult to restrict the passage of a vibrating sieve for sorting rocks and ores, especially flat ones that are larger than the opening size of the bar screen of a resonant vibrating sieve. The purpose is to obtain a bar screen that is possible.

の大きな事を損なわないようにしたものである。For this purpose, projections are formed on the side of the bar plate to regulate the slits in the flow direction.This allows for a sorting accuracy similar to that of woven or punched nets, while not impairing the large throughput of the bar screen. This is what I did.
以下図面に示す実施例について説明する。The embodiments shown in the drawings will be described below.
本案の振動篩は上段枠１と下段枠２とからなるもので、

されている。The vibrating sieve of the present invention consists of an upper frame 1 and a lower frame 2,
The upper frame 1 and the lower frame 2 are arranged vertically at an appropriate interval, and a resonant spring (not shown) is attached to each case through a case 6 protruding from each frame.The upper and lower frames 1 and 2 are connected by a connecting rod 7. ing.
この連結棒７の取付角度は水平に対して３０〜６０°で
ある。The mounting angle of this connecting rod 7 is 30 to 60 degrees with respect to the horizontal.

取付けられている。Also, attach the metal fittings 8, so that the plate spring 4 is perpendicular to the connecting rod 7.
It is fixed to each of the upper and lower frames 1 and 2 at 8', and is attached to the foundation via an installation spring 5 at an equal distance from the combined center of gravity of the assembled upper and lower frames.

ー１ａ、２ａが装着されている。The upper and lower frames are driven by an eccentric drive device 3, and a horizontal beam 9 and a horizontal beam 10 are attached to the upper frame 1 and lower frame 2 of the vibrating body, respectively. bars 1a and 2a are attached.
之等は偏心駆動装置３で上段枠１と下段枠２とが反対方
向に動くことで、之れに同調して反対方向に動く。By moving the upper frame 1 and the lower frame 2 in opposite directions by the eccentric drive device 3, the upper frame 1 and the lower frame 2 move in opposite directions in synchronization with the upper frame 1 and the lower frame 2.
バー１ａ、２ａは又板状で互に隣合った網棒を形成する

て選別粒度を荒くする。The bars 1a and 2a are also plate-shaped and form mutually adjacent mesh rods, but since the flat-sized ones pass through the mesh rods from a place where there is no slit restriction in the flow direction of the raw material, the sorting particle size is determined by this. make it rough.

。Therefore, in the present proposal, a protrusion a is formed on the side of the bar plate,
This allows the slits in the flow direction to be regulated, making it possible to approach the sorting accuracy similar to that of woven or punched nets, without sacrificing the large throughput of bar screens.
突起ａは図示のような波形突起の外任意形状の突起であ

規制することが出来るという特徴がある。In any case, the proposed method performs sieving by vibrating bars adjacent to each other in the same plane alternately in the same direction. The strong impact force prevents clogging, and the ability to sieve while destroying the cross-linking phenomenon caused by the raw materials, making it possible to perform the sieving work efficiently. Of course, it has the feature of being able to restrict the passage of objects (flat objects larger than the opening size of the bar screen).
