Sieve shaker

Abstract

The invention discloses a sieve shaker. The sieve shaker comprises a sieve frame, a sieve tray, a pressing rod assembly and an amplitude amplifying device. The sieve tray and the pressing rod assemblyare both installed on the sieve frame. The pressing rod assembly is positioned above the sieve tray; the amplitude amplifying device is located between the pressing rod assembly and the sieve tray. The amplitude amplifying device comprises an elastic reset component, a first connecting component and a second connecting component. The first connecting part is connected with the sieve tray, the second connecting part is connected with the pressing rod assembly, and the elastic reset part is installed between the first connecting part and the second connecting part so as to guide the first connecting part to be close to or away from the second connecting part in the vertical direction to increase the amplitude of the sieve tray. When the sieve tray vibrates under the effect of the sieve shaker, the sieve tray can drive the first connecting part to vibrate up and down, and meanwhile, the elastic reset part can absorb and release vibration energy transmitted by the first connecting part, so that the amplitude of the sieve tray in the up-down direction is increased, the difficulty of particle sieving is reduced, and the sieving effect is improved.

Description

technical field [0001] The invention is used in the technical field of vibrating sieve machines, and in particular relates to a vibrating sieve machine. Background technique [0002] The vibrating screen machine is a machine that cooperates with the test sieve to analyze the particle size of the material, which replaces the traditional manual screening. When conducting particle analysis tests on soil samples with a particle size of 0.075mm to 60mm, the soil samples should be sieved layer by layer according to sieve trays with different apertures to separate the soil samples with the required particle size. The sieve trays are placed in the vibrating sieve machine from top to bottom according to the pore size from large to small. Under the vibration of the vibrating sieve machine, soil sample particles with different particle sizes fall into the sieve trays with corresponding apertures.

Problems solved by technology

[0003] In the prior art, after the vibrating sieve machine vibrates the soil sample particles for a certain period of time, the soil sample particles do not completely fall into the screen with the corresponding aperture, and the vibration effect is not good, which not only affects the experimental results, but also takes up a lot of personnel.
