Abstract

The utility model relates to a shaking table head of shaking tables. A plurality of shaking tables are used for separating fine heavy minerals. The stroke adjuster is moved from the upper end of a rock arm to the position between the rock arm and a lift plate by the utility model. The utility model solves the problems that a pull rod is moved up and down when the stroke is adjusted so that deviation is produced between the pull rod and the spring centerline under the bed surface, and the normal operation of the shaking table can not be ensured. The utility model can not be stopped when the stroke is adjusted. The stroke adjusting range is widened from 9.1 mm to 24.6 mm to 6 mm to 27 mm, and the weight of a cover plate is reduced by 84%. The utility model has the advantages of convenient operation, convenient maintenance and repair, and low cost. The total weight of the shaking table head is reduced by 1/4 because the measures, such as the eccentric shaft is changed to a rolling bearing, etc.

Description

Swinging head with single pull rod, four shafts, four-bar linkage

The utility model relates to a kind of Gravity Separation equipment, particularly a kind of driving mechanism that is widely used in the shaking table of graded shot heavy mineral, i.e. four four-bar linkage shaking table heads of simplex pull rod.

At gravity mill, generally adopt a large amount of shaking tables to separate fine-grained heavy minerals, the driving mechanism of shaking table (shaking table head) uses the cam lever shaking table head mostly, but mainly there is following problem in this shaking table head:

When 1, regulating the stroke of shaking table face, pull bar can move up and down, and the spring that bed surface is advanced under the shaking table face is irremovable, therefore the center line of pull bar and spring will produce skew, shaking table can not guarantee to run well, and on multideck table, this problem is more serious especially.

2, be limited to 9.16 millimeters under the stroke, in the time of can not satisfying the fine mineral of sorting, the stroke lower limit should be less than 8 millimeters requirement.

3, the head of a bed covers heavyly 45.5 kilograms, and two male workers just can lift, and all makes troubles for operation, M R.

4, when the spring under the head of a bed and bed surface and the bed surface does not also install, the head of a bed can not remain on duty (be clamp with lift plate thread off), therefore when manufactory's assembling head of a bed, must push against with timber, in operation process, also can thread off Operation and maintenance inconvenience sometimes.

5, the outlet of the pull bar of headstock (casing) is bigger, and sand, water, mud etc. easily are splashed into.

The purpose of this utility model is to overcome the above-mentioned shortcoming of prior art, and a kind of kinetic characteristic and advantage that keeps existing cam lever shaking table head is provided, but mechanical performance is better and be more suitable for the shaking table head of the fine valuable mineral of sorting.

The purpose of this utility model reaches by following approach: the utility model is mainly by pull bar; Casing; Protecgulum; Rocking arm; The semicircle card; Nut; Spring; Pressing plate; Front link rod; Stroke adjuster; Rear link rod; The large eccentricity axle; Roller; Belt pulley; Lifting the parts such as plate and bonnet forms; The large eccentricity axle is installed in the rear portion of shaking table head; The supporting of employing rolling bearing; One end of large eccentricity axle stretches out casing; Driving pulley is installed in its end; The end of large eccentricity axle in casing; Insert in the endoporus of roller; Roller with lift plate and join; The rear end of lifting plate is enclosed within on the fixed axis; The up and down two ends of rear link rod connect with the little axle of the little axle of lifting the front bottom of plate and stroke adjuster rear end respectively; Lifting plate and stroke adjuster joins together; The lower end of rear link rod is that both sides are asymmetric (short on one side; Another length of side) be stuck in clamp on the little axle of stroke adjuster tail end; Front link rod joins stroke adjuster and rocking arm together; Little axle on the anterior slideway of the rear end of front link rod and stroke adjuster connects; Rotatable adjusting handle is housed on the stroke adjuster; The rotation adjusting handle can change the position of little axle on the slideway and change the stroke of shaking table; The front end of front link rod is that the top is longer; The following short clamp that is stuck on the little axle in rocking arm lower end; There is a hole of inserting fixed axis at the middle part of rocking arm; After living from the rear surface of rocking arm epimere the semicircle card is installed successively; The nut of location hinge connection; Spring and pressing plate; The rear end of pull bar connects with nut; The leading portion of pull bar stretches out forward from the hole on the casing, and its front end connects with the shaking table face.

Compared with prior art, the utility model possesses following major advantage:

When 1, regulating stroke, pull bar can not move up and down, thereby shaking table can guarantee normal operation, and can not shut down during the adjustment stroke.

2, the adjustable range of stroke is wide, can adjust between 6～26 millimeters, can satisfy the different requirements that sort various different grain size mineral, can improve the valuable mineral rate of recovery.

3, head of a bed top cover is divided into two (protecgulum and bonnets), and the weight of the existing head of a bed of its weight ratio reduces by 84%, is convenient to operation, maintenance and repairing.

4, head of a bed inside is provided with spring, and the clamp that adds back link rod lower end and preceding link rod front end is both sides dissymmetrical structure (longer on one side, another side is shorter), can accomplish that internals do not thread off, and is convenient to install and operation.

5, the bearing of large eccentricity axle adopts rolling bearing, reduces manufacturing expense, reduces running power, turns round steadily, and noise is little.

6, head of a bed tie rod hole is little, and ore pulp and other foreign material are difficult for entering casing.

7, head of a bed gross weight reduces by 1/4 than original, and cost is lower.
