一、用  途

Ⅰ.Use

LY型摇床是供实验室开展矿石可选性研究、试验和小型选厂等进行重力选矿常用的设备之一。适用于细粒和微细粒稀有金属、黑色金属、有色金属、贵重金属等矿石和煤的选别。它不仅可以作为一个独立的选矿作业，亦可以与跳汰机、螺旋选矿机、离心选矿机等或其他选取矿方法配合使用。本产品由原地矿部唯一指定企业生产，执行行业标准。

本设备依据入选矿物比重差和在往复不对称运动并呈倾斜的床面横向水流中的分层性能进行选别。具有不同比重矿物在床面上分带明显，精矿质量高、操作和调节方便等特点。

摇床面结构有矿砂、矿泥之分，材质分别有玻璃钢或铝合金。

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、总图及主要结构说明

III. General Drawing and Main Structure

本机由床头箱，床面，机架，三个主要部分组成。

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

1、床头箱的构造为双曲连杆机构，当偏心轴转动时，带动连杆作上下运动。连杆向下运动，肘板张开。右方的肘板支持在与拉杆固定在一起的支座上，左方肘板则支持在可调动的支座上(此座只限上下移动)，通过特制螺栓和支座安装在一起。弹簧的一端套在支座上上，另端套在固定套管上的调整螺柱盘上。

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.

从电动机通过的此带轮得到动力转动偏心，带动边杆向下推动肘板压缩弹簧，推动拉杆向前带动床面；当连杆向上时，利用弹簧张力，推动床面向后运动，这样运动连续起来，则旋转运动变为纵向直线往复运动。

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.

冲程大小，扭转特殊螺柱而获得，整个机构都放在一个床头箱壳中。

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

2、摇床的工作部份，是一个铝合金制成的床面，其外形为不规则的四边形。

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，并喷黑色漆3-4次。过去的来复条改用刨槽，槽的排列与床面摇动方向平行，靠近床面上的给矿端处的槽较短，越往下越长，它们的终点排列在离床面排矿端处距离为50毫米的对角线上。

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.

顺着床面上边缘，靠床头箱一侧的角上，有给料箱，与给料箱平列有水槽，均用有机玻璃制成，用以加给冲洗水。冲洗水通过槽底固定着可转动的菱形胶闸块流到床面上，改变菱形胶闸块的角度的位置，可调节水量和水流的方向，此给料箱装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、床面安装在两根铸铁横梁上，串通横梁固定着滑动轴承上，而轴承固定在角钢机架上。

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.

床面在横向有倾斜角度，它的倾斜角可由0度～10度，调节横向角度的滑动轴承，中间处手轮，手轮轴一端是螺杆，与具有弧形槽的螺母相配合，该螺母与固定在拉杆上的连相滑动配合，当手轮转动螺母向一方移动带着连杆拉杆以及床面一起转动而实现。

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
