Abstract

The utility model relates to a double function vibrator for an experiment, comprising a tank body, a vibrating table and an objective table. The utility model is characterized in that the vibrating table is supported by four tower springs and pulled by two pairs of crossed side drawing springs. Because of the rotation of a rotating shaft with an eccentric block, which is arranged in a bearing seat at the bottom surface of the vibrating table, the vibrating table can make side-to-side movement and be also vibrated in three directions. In addition, the utility model can be added with a bracket and a vibrating sieve which is connected with the vibrating table. The vibrator has simple structure, small size and light weight and especially saves electric energy (The motor power is about ten watts). The utility model can be conveniently used and widely used in a physics test, a chemic test, a biologic test, etc.

Description

The difunctional bobbing machine of experiment

The utility model relates to a kind of institution of higher learning, the difunctional bobbing machine that scientific research institution, industrial enterprise use in the laboratory.

The ZD-4 type klystron oscillator machine complex structure of Jintan, the Jiangsu county enviromental protection instrument factory product of selling in the market, power consumption is big, the cost height, and only can be shimmy along a direction.

The purpose of this utility model is to overcome weak point in the prior art, and provides a kind of energy-conservation, the difunctional bobbing machine that the laboratory is used.

The purpose of this utility model can reach by following technical scheme.The difunctional bobbing machine of this experiment, it comprises casing, and shake table can be assigned the examination villous themeda, and the objective table of beaker is characterized in that:

4 turriform springs that support shake table vertically upward are installed in place, 4 angles of casing respectively.

One end of the layback spring of 2 pairs of intersections is fixed on the place, 2 long limits of casing, and the other end is fixed on the bottom surface of shake table.

The motor rotary shaft that is installed in casing central authorities links to each other with the rotating shaft that has eccentric block in being installed in shake table bottom central part position bearing block by the axle sleeve spring.

The vibratory sieve of can also additional body and linking to each other with shake table.

The difunctional bobbing machine of this experiment usefulness compared with prior art has simple in structure, and volume is little, in light weight, multiple functional, easy to operate, mode of vibration is adjustable, advantages such as cost is low, saving electric energy.

Fig. 1 a is the front view of this bobbing machine.

Fig. 1 b is the left view of this bobbing machine,

Fig. 1 c is the upward view of this bobbing machine,

Now in conjunction with the accompanying drawings, the utility model is further described.

With reference to Fig. 1 a, 1b, 1c, on the spring base 2 at the place, 4 angles of casing 1,4 turriform springs 3 are installed, the gap of turriform spring 3 and casing 1 inwall is one of the factor that influences the swinging distance of

turriform spring

3,4 turriform springs of installing vertically upward 3 are supporting shake table 4, and the objective table 5 of assigning test tube and beaker is fixed on the shake table 4, the rotating shaft of motor 6 that is installed in casing 1 central authorities is by linking to each other with the rotating shaft that has eccentric block 9 in being installed in shake table 4 bottom bearings 8 as the axle sleeve spring 7 of flexible axle, and power of electric motor is about 10W.One end of two pairs of intersection layback springs 10 is installed in respectively on the long limit spring base of casing 1, and the other end links to each other with extension spring seat 11 on shake table 4 bottom surfaces respectively, the effect of two offside extension springs 10 is to be used for balance and stable vibration platform 4, and weakens up and down shimmy of shake table 4 front and back.

When adjusting motor controller 12, in order to change the rotating speed of motor 6, under slow-revving situation, because the effect of the turning cylinder eccentric block 9 of rotation, shake table 4 periodically swings, and under high-revolving situation, will cause the vibration of shake table 4 on three directions.

Can add a support in addition, and the vibratory sieve that links to each other with shake table 4, in order to a screening material, powdered rubber or to the filtration of solution, so that satisfy the needs of various experiments better.

Claims

1, the difunctional bobbing machine of a kind of experiment, it comprises casing, and shake table can be assigned test tube, and the objective table of beaker is characterized in that:

4 turriform springs that support shake table vertically upward are installed in place, 4 angles of casing respectively,

One end of 2 pairs of intersection layback springs is fixed on 2 long limits of casing, and the other end is fixed on the bottom surface of shake table,

The motor rotary shaft that is installed in casing central authorities links by axle sleeve spring and the rotating shaft that has eccentric block that is installed in the bearing block of shake table bottom central part position.

The difunctional bobbing machine of 2 experiments according to claim 1 is characterized in that adding a support, and a vibratory sieve that links to each other with shake table.
