一、用  途

Ⅰ.Use

LY型搖床是供實驗室開展礦石可選性研究、試驗和小型選廠等進行重力選礦常用的設備之一。適用于細粒和微細粒稀有金屬、黑色金屬、有色金屬、貴重金屬等礦石和煤的選別。它不僅可以作為一個獨立的選礦作業(yè)，亦可以與跳汰機、螺旋選礦機、離心選礦機等或其他選取礦方法配合使用。本產品由原地礦部唯一指定企業(yè)生產，執(zhí)行行業(yè)標準。

本設備依據(jù)入選礦物比重差和在往復不對稱運動并呈傾斜的床面橫向水流中的分層性能進行選別。具有不同比重礦物在床面上分帶明顯，精礦質量高、操作和調節(jié)方便等特點。

搖床面結構有礦砂、礦泥之分，材質分別有玻璃鋼或鋁合金。

LY Shaking Table is one of the commonly used equipment to conduct gravity concentration for feasibility study and test of ores for labs. and small beneficiation plant. It is applicable for separations of fine-grained and micro-grained rare metal, ferrous and non-ferrous metal, precious metal , coal and other minerals. It can carry out ore concentration operation independently and also can operate in conjunction with jig, screw separator, centrifugal separator and other equipment. The product is made by the only manufacturer designated by the former Ministry of Geology and Mineral Resources, in compliance with the Industrial standards.

LY Shaking Table is to make separations based on the difference of specific gravity of feed materials, reciprocating asymmetrical movement and the stratification performance of the inclined table surface in the lateral water flow with obvious zone of the minerals with different specific gravities on the table, high quality of concentrates produced, convenient operation and adjustment and other features.

The table surface is constructed of ore sand or slime and is made up of glass fibre reinforced plastic or aluminum alloy.

三、總圖及主要結構說明

III. General Drawing and Main Structure

        本機由床頭箱，床面，機架，三個主要部分組成。

This machine mainly consists of  table box, table surface, and table frame.

1、床頭箱的構造為雙曲連桿機構，當偏心軸轉動時，帶動連桿作上下運動。連桿向下運動，肘板張開。右方的肘板支持在與拉桿固定在一起的支座上，左方肘板則支持在可調動的支座上(此座只限上下移動)，通過特制螺栓和支座安裝在一起。彈簧的一端套在支座上上，另端套在固定套管上的調整螺柱盤上。

1. The table box is hyperbolic  link mechanism. When the eccentric shaft rotates, it drives the upward and  downward movement of the connecting rod. When the connecting rod moves  downward, the toggle plate expands. The toggle plate on the right is supported  on the supporting seat fixed with the draw bar while the toggle plate on the  left is supported on the adjustable supporting seat (this seat can only move  upward and downward), which is installed together with the supporting seat  through special bolts. One end of spring is covered on the supporting seat and  the other end is covered on the adjusting stud disk above the fixed sleeve.

從電動機通過的此帶輪得到動力轉動偏心，帶動邊桿向下推動肘板壓縮彈簧，推動拉桿向前帶動床面；當連桿向上時，利用彈簧張力，推動床面向后運動，這樣運動連續(xù)起來，則旋轉運動變?yōu)榭v向直線往復運動。

The belt pulley passing the  motor is driven to rotate. It drives the connecting rod and pushes downward the  toggle plate to press the spring, as well as pushes the draw bar to carry the  table surface forward. When the connecting rod moves upward, it drives the table  surface to move backward under the action of spring tension. By doing it, the  motion becomes continuous. The rotary motion becomes longitudinal straight  reciprocating motion.

沖程大小，扭轉特殊螺柱而獲得，整個機構都放在一個床頭箱殼中。

The stroke is obtained through  the twisting of special stud. The whole mechanism is put in the shell of table  box.

2、搖床的工作部份，是一個鋁合金制成的床面，其外形為不規(guī)則的四邊形。

2. The working part of shaking  table is a table surface made of aluminum alloy. Its appearance is an irregular  quadrangle.

床面的表面上漆灰，并噴黑色漆3-4次。過去的來復條改用刨槽，槽的排列與床面搖動方向平行，靠近床面上的給礦端處的槽較短，越往下越長，它們的終點排列在離床面排礦端處距離為50毫米的對角線上。

Paint the outside of table  surface with ash and spray black lacquer for 3 to 4 times. The original rifle  bar can be replaced with dadoing. The dadoing is arranged in parallel with the  shaking direction of table surface. The dadoing near the feeding end on the  table surface is short. It become gradually long as the lower part of it  becomes. Their finishing points are arranged on the diagonal 50mm away from the discharging end of table  surface.

順著床面上邊緣，靠床頭箱一側的角上，有給料箱，與給料箱平列有水槽，均用有機玻璃制成，用以加給沖洗水。沖洗水通過槽底固定著可轉動的菱形膠閘塊流到床面上，改變菱形膠閘塊的角度的位置，可調節(jié)水量和水流的方向，此給料箱裝在床面的右角上故叫右式。

There is feeding box along the  end of the table surface and next to the corner at the one side of the table  box. A water tank is parallel to the feeding box. Both of them are made of  organic glass and are used to add flushing water. The flushing water flows to  the table surface through rotatable rhombus rubber brake block fixed at the  bottom of tank, and change the position of the angle of the rhombus rubber  brake block. The water flow and its direction can be adjusted. Such feeding box  is installed in the right corner of the table surface, hence called right  feeding box.

3、床面安裝在兩根鑄鐵橫梁上，串通橫梁固定著滑動軸承上，而軸承固定在角鋼機架上。

3. The bed surface is installed  on the two cast iron beams. The beams are fixed on the sliding bearings and the  bearings are fixed on the angle iron frame.

床面在橫向有傾斜角度，它的傾斜角可由0度～10度，調節(jié)橫向角度的滑動軸承，中間處手輪，手輪軸一端是螺桿，與具有弧形槽的螺母相配合，該螺母與固定在拉桿上的連相滑動配合，當手輪轉動螺母向一方移動帶著連桿拉桿以及床面一起轉動而實現(xiàn)。

There is inclination  angle for the table surface horizontally which can be from 0° to 10°. Adjust  the horizontal sliding bearing and hand wheel in the middle. At the one end of  the hand wheel shaft which match the nut with arc groove. Such nut matches the  connecting rod fixed on the draw bar. When the hand wheel turns to the  direction of nut, it drives the rotation of connecting rod, draw bar, and table  surface
