Prediction, which requires the simulation of actual engineering geological conditions with corresponding materials. However, the physical properties of various materials are very different. In many cases, a small change in the amount of the material itself will cause a great change in the simulated formation conditions. Therefore, if material loss, uneven mixing or If the mixing time is too long, some or all of the physical properties of the materials will change, which will directly lead to a large difference in the simulation of the formation conditions, resulting in the failure of the experiment.

在本发明的一种实施例中，所述壳体端部还设有防尘盖8，防止物料溢出。In one embodiment of the present invention, a dustproof cover 8 is provided at the end of the housing to prevent material from overflowing.
本发明的工作过程如下：Working process of the present invention is as follows:
将各种物料的配比经过精密的计算后，进行精确的称量，然后将物料倒入混合装置主体1进行混合，在混合过程中盖上防尘盖8以防止物料溢出。混合时打开电动机开关，电动机会带动与其连接轴转动，直接使得装置内内部中心三角搅拌轴转动，并通过与连接轴相对固定的齿轮带动中间过渡齿轮14转动。由于中间过渡齿轮14通过轴承直接固定在最外层的壳体结构上，所以过渡齿轮14会使得外部搅拌叶相对于内部的三角搅拌轴向相反的方向转动。且外部搅拌叶10与最外部壳体间接触较为紧密，使得内部物料可以在正反旋转力的作用下充分均匀的混合。After precise calculation of the ratio of various materials, carry out accurate weighing, and then pour the materials into the main body 1 of the mixing device for mixing, and cover the dust-proof cover 8 during the mixing process to prevent the materials from overflowing. Turn on the motor switch when mixing, and the motor will drive its connecting shaft to rotate, directly making the inner center triangular stirring shaft in the device rotate, and drive the intermediate transition gear 14 to rotate through the gear relatively fixed to the connecting shaft. Since the intermediate transition gear 14 is directly fixed on the outermost shell structure through bearings, the transition gear 14 will cause the external stirring blades to rotate in opposite directions relative to the internal triangular stirring shaft. Moreover, the contact between the outer stirring blade 10 and the outermost casing is relatively close, so that the inner materials can be fully and evenly mixed under the action of positive and negative rotational forces.
在将物料混合均匀后，可打开防尘盖8向内部加入适当的溶剂，将混合后物料与溶剂进行再次充分混合后，可通过尾部旋转液压缸4使得壳体结构翻转，将物料倒出后进行压实，以模拟实际地层条件。After the materials are mixed evenly, the dust cover 8 can be opened to add an appropriate solvent to the inside, and after the mixed materials and the solvent are fully mixed again, the shell structure can be turned over by rotating the hydraulic cylinder 4 at the tail, and the materials are poured out Compaction is performed to simulate actual formation conditions.
