Soil test remolded soil preparation appearance
Technical Field
The utility model belongs to civil engineering test field relates to a soil sample preparation appearance, specifically is geotechnical test remolded soil preparation appearance.
Background
The soil in nature is a heterogeneous, multiphase and porous discontinuous medium consisting of mineral particles and multiminerals such as liquid, gas and the like existing in the pores of the mineral particles, and the properties of the soil are complicated and changeable due to the heterogeneity and complexity of the constituent substances. The geotechnical test can obtain various physical and mechanical parameters of the soil sample, and provides a basis for engineering design or numerical calculation. The general geotechnical test needs to study disturbed soil, so that the natural soil needs to be reshaped. A large amount of dust is generated in the process of remodeling the soil, so that the soil is unfavorable for human bodies; meanwhile, sundries are easy to enter, so that experimental results generate errors; meanwhile, when the amount of remolded soil is large, great manpower and material resources are wasted. When the water content is used for preparing remolded soil, the water content loss caused by nonuniform manual mixing and overlong time can cause adverse effects on experimental results.
In order to solve the above problems, some devices have been used in the prior art for remoulded soil preparation. For example, the Chinese utility model No. 201620181688.2 discloses a rolling device for remolded soil, which needs manual force application and can only roll and crush soil, and the soil crushing efficiency is not high when the function is too single; like the utility model No. 201811519119.4, the utility model discloses a cube remolded soil sample preparation appearance still needs a large amount of manpower and remolded efficiency is not high.

The working principle of the soil test remolded soil preparation instrument lies in: the particle size of remolded soil particles is controlled by selecting the vibrating screening net meeting the required aperture, after the dry soil blocks which are fully dried are poured into the feed inlet, the crushed soil falls on the vibrating screening net under the action of the crushed soil roller with the veins, the vibrating screening net works under the action of the vibrator, the sieved crushed soil falls on the feed inlet provided with the integrated balance under the action of gravity, when the unscreened soil reaches a certain amount, the unscreened soil can be discharged from the unscreened soil outlet by opening the gate of the unscreened soil outlet under the action of powerful vibration, the crushed soil can be poured into the feed inlet again for reutilization, the mass and the water content of the appointed soil are set by the control device, the gate can be opened after the temporary soil reserve amount under the vibrating screening net meets the requirement, and the crushed soil falls into the stirring barrel. Under the effect of the control device, the quantitative water of the water tank is sprayed in the stirring barrel along with the water injection pipe, the soil stirring machine is used for fully stirring, soil materials which are stirred and finished flow into the soil outlet box through the internal pipeline, and soil which flows into the soil outlet box at the moment is remolded soil required by the experiment.
Advantageous effects
(1) The soil test remolded soil preparation instrument limits the whole process of preparing remolded soil in the instrument, thereby reducing the flying of dust and the entering of sundries in the preparation process; (2) the preparation instrument saves most of the manpower work; (3) the preparation instrument avoids the uneven manual mixing and the water content loss caused by overlong time when the water content is applied to prepare remolded soil.
