Problems solved by technology
[0002] At present, traditional test sample preparation instruments all use one-way force to realize sample preparation, and one-way force will make the density index of sample preparation generally exist inhomogeneity, which not only brings great influence on the test results error, which shadows the effect of the experiment

Embodiment Construction
[0015] Such as figure 1 As shown, the structure of the push-type two-way sample preparation instrument of the present invention includes two U-shaped connecting rods 4 and a workbench 7. Be fixed on the workbench 7 on the ground. The openings of the two U-shaped sleeves are opposite, and the two U-shaped connecting rods 4 are fixed at the ports on one side of the workbench and are provided with a pressure plate 9; the two ends of the other side are connected by elastic, and the elastic connection between the connecting rods is through The card slot 2 with the ball 5 inside is connected, and the card slot 2 is covered with a card sleeve, such as figure 2 and image 3 shown.
[0016] The U-shaped sleeve 3 is provided with a ball 5, and the U-shaped connecting rod 4 can roll left and right in the U-shaped sleeve through the ball 5. A handle 1 is installed on the two elastically connected connecting rods, and the "clamping" and "releasing" of the connecting rods are controlle...

The invention discloses a horizontally push-type bidirectional sample preparation instrument, comprising two connecting rods and a workbench, wherein, the connecting rods are loaded into a sleeve which is fixed on the workbench via a bracket; each of the opposite ends of both connecting rods is provided with a pressurizing plate, and the other ends of the two connecting rods are elastically connected; a clamping cylinder is arranged between the two pressurizing plates, and a filling mold is clamped in the clamping cylinder; a sample preparation container is arranged inside the filling mold. By using a horizontally push-type bidirectional mechanical control mode to lead a sample to achieve the effect of bidirectional even stress in sample preparation process instead of unidirectional stress mode in the traditional method, thus the common problem of unevenness density indexes of sample preparation is solved.
Description
technical field [0001] The invention relates to a sample preparation instrument, in particular to a mechanical sample preparation device for remolding soil, which belongs to a geotechnical sample preparation instrument. Background technique [0002] At present, traditional test sample preparation instruments all use one-way force to realize sample preparation, and one-way force will cause the ubiquitous inhomogeneity of the sample preparation density index, which not only brings great influence on the test results error, which affects the effect of the experiment. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned deficiencies in the prior art and provide a horizontal pushing bidirectional sample preparation instrument. The horizontal pushing bidirectional mechanical control mode of the instrument enables the sample to be evenly stressed from two directions and improves the test effect. [0004] The technical solution a...
