Abstract

The utility model relates to an energy-saving shaking table, comprising a table body, a relative support, and a drive bedside, which is characterized in that rollers are arranged on an eccentric drive shaft in a headstock, a rocker arm is arranged under the rollers, the other end of the rocker arm is fixed on a support arm shaft at one side of the rollers, and the lower of the rocker arm is connected with one end of a swigging arm through a joint lever. The swing arm is fixed on the swing arm shaft on the other side of the rollers, and the other end of the swing arm is connected with a draw rod arranged with a spring. The other end of the draw rod is connected with the table body. Current sliding friction is changed to rolling friction in the utility model, therefore the mechanical friction force is lowered and the useless power for overcoming friction is reduced. The power consumption is reduced from 1.5Kw to 0.37 Kw, the vibration is diminished, and the noise is lowered. Users do not have to inject lube into the box, therefore oil leakage is stopped, environment pollution is avoided, and box weight is lowered. And the utility model uses an adjustable brace to replace the cumbersome cement peg, which makes installment and adjustment simple, swift, safe and reliable.

Description

A kind of energy-conservation shaking table

Technical field

The utility model relates to a kind of shaking table, and the shaking table that especially a kind of ore dressing is used belongs to mining machinery design and manufacturing technology field.

Background technology

Shaking table is a kind of equipment of industrial sorting material, is applicable to the metal of difference of specific gravity, the gravity treatment of nonmetallic mineral.The present shaking table that uses has multiple, cloudlike tin shaking table, CC-2 shaking table, 6-S shaking table or the like.The structure one of these shaking tables is that the copper sheathing sliding bearing is set in headstock, and need inject a large amount of machine oil in case is lubricated it, the 2nd, the bed surface bottom needs to support with powerful concrete column, and under bed surface mounting spring, and the supporting base bed surface under also is the employing sliding friction.The structure that these volumes are big and heavy not only brings frictional force big, and vibration is big, and the power consumption height will could drive with the motor of 1.5kw, the electric motor starting difficulty, need forward big belt pulley to a certain ad-hoc location with manpower could start, and difficulty is installed, carrying inconvenience, the cost height, the cycle is long.Copper sheathing in headstock source is limited in addition, and the cost height, in the running damage of each parts fast, directly influence its service life, the noise height causes bigger harm to surrounding environment simultaneously, working environment is directly polluted in the very easily leakage of oil of lubricating oil in the case.Therefore, be necessary prior art is improved.

Summary of the invention

Big for overcoming the wearing and tearing that prior art exists, the power consumption height, noise is big, and is seriously polluted, the high deficiency of cost, it is a kind of simple in structure, safe and reliable that the utility model provides, free of contamination energy-conservation shaking table.

The utility model is realized by following technical proposal: a kind of energy-conservation shaking table, comprise a body and support member thereof and the power head of a bed, it is characterized in that the power eccentric shaft in the headstock is provided with roller, the roller below is provided with the rocking bar support arm, the rocking bar support arm other end is fixed on the support arm shaft of roller one side, rocking bar support arm below links to each other with rocking arm one end by connecting rod; rocking arm is fixed on the rocker arm shaft of roller opposite side; the other end of rocking arm links to each other with the pull bar which is provided with spring, and the pull bar other end links to each other with the bed body.

The side that described rocking bar support arm links to each other with roller is made as arcwall face, and arcwall face is provided with oil groove, is used for lubricating and preventing mechanical wear.

Described power eccentric shaft links to each other with electric machine main shaft by belt pulley set, belt or chain wheel set, sprocket wheel, so as under driven by motor, to make eccentric shaft and on the roller rotation.

Described bed body support member is by being fixed on a universal joint at the body back side, the pole that links to each other with universal joint is located at the pole lower end and the axle sleeve that is fixed on the frame constitutes, by this support member, shaking table is together shaken with head of a bed power part, realize the gravity separation of mineral on the bed surface.

The utility model compared with prior art has following advantage and effect: adopt such scheme, promptly change the existing glide friction and be rolling friction, reduced mechanical friction power, reduced, made power consumption drop to 0.37kw by original 1.5kw to overcoming the idle work that friction is done, reached energy-conservation effect, simultaneously, vibration reduces, and improve the service life of each parts, noise reduces, environment is purified, and other need not to inject lubricating oil in casing, has stopped leakage of oil, no longer environment is polluted, casing can adopt open, has reduced weight, has reduced cost, spring is changed between the bed surface and the head of a bed under bed surface, replace heavy concrete stake with adjustable cramp bar simultaneously, make installation and adjusting simpler and easy quick, safety and reliability, therefore, be an ideal, practical energy-conservation shaking table.
