Problems solved by technology

[0013] 1. Screening device, the relative displacement distance between the sample and the screen is short, the screen is easy to block, and the screening efficiency is low
[0014] 2. The vibration device, the relative displacement distance between the sample and the vibration container is short, the vibration is uneven or the vibration time is long, etc., the effect is relatively poor
[0015] 3. The screening device and the oscillating device are independent of each other and cannot be used in common use. The purchase cost of the device is high and the utilization rate is low

Embodiment 1

[0070] Each elastic member is a vertical support spring, one end of each vertical support spring is fixedly connected with the top or bottom edge of the fixed square frame 105, and the other end of each vertical support spring is fixedly connected with the top plate 201 or the bottom plate 204 .

[0071] The quantity of vertical support spring is preferably two, is respectively upper vertical support spring 104 and lower vertical support spring 109, wherein, the bottom of upper vertical support spring 104 is fixedly connected with the top center of fixed square frame 105, and upper vertical support spring The top of the support spring 104 is fixedly connected to the bottom center of the triangular long side of the top plate 201; The bottom center of the box 105 is fixedly connected.

[0072] Since the distance between the left and right sides of the fixed frame 105 and the support 203 is small, the vertical support spring is generally 10mm.

[0073] Alternatively, the number...

Embodiment 2

[0075] Each elastic component is a side tension spring 110 , one end of each side tension spring 110 is fixedly connected to the side of the fixed frame 105 , and the other end of each side tension spring 110 is fixedly connected to the corresponding bracket 203 .

[0076] The number of side tension springs 110 is preferably two or four, which are arranged symmetrically around the longitudinal central axis of the fixed frame 105 .

[0077] Because the distance between the left and right sides of the fixed frame 105 and the support 203 is large, the elastic properties of the side tension spring 110 or the side tension rubber band are different, and the length of the side tension spring 110 or the side tension rubber band is generally 40-80 mm.

Abstract

The invention discloses a vertical pulse type electric oscillating screening machine and a method for using the same, comprising a support frame, a fixed frame, a vertical pulse driving device and an oscillating screening device. Each elastic part is fixedly connected with the support frame; a vertical gear rack is arranged on the top of the fixed frame; the upper part of the support frame is provided with an incomplete gear that meshes with the gear rack; the incomplete gear, the gear rack and several elastic parts The vertical pulse driving device is formed together; the vibrating screening device and the fixed frame form an integral structure, and under the action of the vertical pulse driving device, periodic vertical pulse motion is carried out. After the above structure and method are adopted, the functions of sieving and oscillation can be realized at the same time, the clogging of the sieve can be avoided, and the efficiency of the sieve can be improved; It can also achieve various screening functions through different combinations of screen meshes to improve the screening or oscillation effect.

Description

technical field [0001] The invention relates to an electric oscillating sieving machine and its usage method, in particular to a vertical pulse electric oscillating sieving machine and its usage method. Background technique [0002] In the field of scientific research, samples must undergo sample pretreatment before analysis, which has an important impact on the efficiency and accuracy of sample analysis. However, the sample preparation stage is often the most time-consuming and labor-intensive process. [0003] In the basic research of soil science, soil and water conservation research, as well as the hot attention and in-depth research on soil pollution phenomena in recent years, it is often necessary to analyze the soil to obtain corresponding experimental data. Grinding and sieving of soil samples is an important process. Part of the test analysis, especially the chemical composition analysis, is often carried out from the leaching solution. In order to fully extract t...
