Abstract
Description
Technical Field
[0001] The utility model relates to the field of shear force test tools, in particular to a shear force test soil compactor. Background Art
[0002] The shear test is used to measure the shear strength and internal cohesion of the sampled soil. It is a test commonly used in civil engineering. The soil sample taken out by the ring knife is generally pressed vertically into the shear box by the thumbs of both hands. The soil pressing process is completed by the thumbs of both hands at the same time. This soil pressing method is not only inefficient, but also inevitably causes deformation of the sample soil, affecting the test results. Utility Model Content
[0003] The utility model aims to provide a shear force test soil compactor to solve the above technical problems.
[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a shear test soil compactor, including a handle, a tee, a sliding column, a limit groove, a pressure block, a fixing hole, and a positioning push box, the handle being respectively fixed to the left and right interfaces of the tee, the sliding column being fixed to the bottom interface of the tee, the limit groove being axially opened at the side end of the sliding column, a fixing hole being opened in the middle of the top end of the pressure block, and the sliding column fixing the pressure block through the fixing hole, and the positioning push box being installed on the sliding column.
[0005] On the basis of the above technical scheme, the positioning push box includes a positioning block, a positioning groove, a sample push port, a sliding hole, a sliding rail, and an exhaust hole. A positioning groove is opened at the bottom end of the positioning block, the sample push port is opened in the middle of the positioning groove, and the pressure block corresponds to the inside of the sample push port. The sliding hole is opened to the sample push port through the top of the positioning block, and the sliding column is slidably connected to the sliding hole, the sliding rail is fixed to the side end of the sliding hole, and the sliding rail corresponds to the limit groove, and the exhaust holes are distributed on the side end of the positioning block.
[0006] Based on the above technical solution, the positioning block is positioned at the top of the shear box through the positioning groove to press the soil.
[0007] Compared with the prior art, the utility model has the following advantages: the utility model uses a T-shaped soil compacting structure held by both hands, in conjunction with a positioning push box for positioning, to maintain stable sample compacting in a cutting box, thereby improving soil compacting efficiency and ensuring the accuracy of test results.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0014] like Figures 1 to 4 As shown, a shear force test soil compactor includes a handle 1, a tee pipe 2, a sliding column 3, a limiting groove 4, a pressing block 5, a fixing hole 6, and a positioning push box 7. The handle 1 is respectively fixed to the left and right interfaces of the tee pipe 2, the sliding column 3 is fixed to the bottom interface of the tee pipe 2, the limiting groove 4 is axially opened at the side end of the sliding column 3, a fixing hole 6 is opened in the middle of the top end of the pressing block 5, and the sliding column 3 fixes the pressing block 5 through the fixing hole 6, and the positioning push box 7 is installed on the sliding column 3.
[0015] The positioning push box 7 includes a positioning block 8, a positioning groove 9, a sample push port 10, a sliding hole 11, a sliding rail 12, and an exhaust hole 13. The positioning block 8 has a positioning groove 9 at the bottom end, the sample push port 10 is opened in the middle of the positioning groove 9, and the pressing block 5 corresponds to the inside of the sample push port 10. The sliding hole 11 is opened to the sample push port 10 through the top of the positioning block 8, and the sliding column 3 is slidably connected to the sliding hole 11, the sliding rail 12 is fixed to the side end of the sliding hole 11, and the sliding rail 12 corresponds to the limiting groove 4, and the exhaust holes 13 are distributed on the side end of the positioning block 8.
[0016] The positioning block 8 is positioned at the top of the shear box through the positioning groove 9 to press the soil.
[0017] The working principle of the utility model is as follows: during the sample loading and soil pressing stage, the ring knife with the sample soil is placed on the opening of the shear box, and the positioning block 8 of the soil presser is buckled on the shear box through the positioning groove 9, so that the ring knife with the sample soil enters the bottom of the sample pushing port 10, and the handle 1 is held by hand to press down the slide column 3, and the slide column 3 along the slide hole 11 is maintained by the slide rail 12, and the pressing block 5 is pressed down in the sample pushing port 10 to press the sample soil in the ring knife into the shear box.
