Vacuum stirring barrel for soil tests

Abstract

The invention discloses a vacuum stirring barrel for a soil test. The vacuum stirring barrel comprises a stirring barrel body, a supporting frame, a stirring mechanism, an operation table, a rotating wheel, a rotating speed handle and the like. The supporting frame is connected with the stirring barrel, a discharge port is formed in the side wall of the stirring barrel, a barrel cover is arranged above the stirring barrel, and a vacuum meter, a vacuum connector, an eyepiece and a motor support are arranged at the top of the barrel cover; the upper end of the stirring rod penetrates through the barrel cover and is connected with the driving motor, the lower end is connected with stirring blades, a sealing ring is arranged between the barrel cover and the stirring barrel, the barrel cover and the stirring barrel are fixed through screws, and the barrel cover is connected with the driving rod through a connecting frame; during discharging, the stirring barrel can be inclined by adjusting the rotating wheel, so that discharging is facilitated; in the stirring process, the stirring condition of the materials can be observed through the eyepiece; after stirring is completed, the barrel cover is lifted, and the lifting speed can be controlled through a handle on the operation table; and the rotating speed of the stirring blades can be controlled by controlling the positive and negative switch to enable the stirring blades to rotate positively and negatively and adjusting the rotating speed handle, so that the stirring speed and uniformity are improved.

Description

technical field [0001] The invention relates to the technical field of vacuum mixing barrels, in particular to a vacuum mixing barrel used for geotechnical tests. Background technique [0002] In the model test in the field of geotechnical engineering, it is often necessary to use a stirring device to mix the soil to make a sample, but the conventional stirring device cannot avoid the influence of air bubbles, and it is difficult to ensure that the saturation and uniformity of the soil sample meet the requirements, so Generally, a vacuum mixing barrel device is required. [0003] In addition, since most of the equipment of the vacuum mixing tank is concentrated on the lid of the mixing tank, the weight of the lid itself is increased, and the operator needs to open the lid when filling and unloading. At this time, the weight of the lid will increase. It is difficult to operate, and because the vacuum mixing tank is generally fixed, it takes time and effort to load and unload...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a vacuum mixing tank for geotechnical tests, which can specifically solve the problems of uneven stirring, low saturation and inconvenient loading and unloading during sample preparation.
