[0002] The direct shear apparatus is an instrument used to measure the shear strength of soil. Usually four soil samples are used. Horizontal forces are applied to shear the samples under different vertical pressures to obtain the shear stress at failure. Then, the shear strength parameters, internal friction angle and cohesion of the soil are determined according to Coulomb's law.

DETAILED DESCRIPTION

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the above structure, through the arrangement of the main body 1, straight cylinder 2, limit rod 12, pressure spring 13, positioning block 15, and slider 14, when the user performs a direct shear test on the soil through the direct shear instrument, there is no need to manually increase the pressure on the vertical surface of the soil by adding weights. The user only needs to drive the take-up wheel 10 to rotate through the output shaft of the motor 9 to make the wire rope 26 generate a pulling force on the positioning block 15, so that the positioning block 15 descends, thereby achieving the effect of increasing the pressure. The automatic pressure adjustment method replaces the manual change of the pressure on the vertical surface of the soil, thereby improving the user's direct shear test efficiency on the soil.

[0022] In a preferred embodiment: the end of the wire rope 3 away from the rotating rod 4 is fixedly assembled with the outer wall of the positioning block 15, and the end of the wire rope 2 6 away from the take-up wheel 10 is also fixedly assembled with the outer wall of the positioning block 15, and the outer wall of the slider 14 is slidably connected with the inner wall of the straight cylinder 2.

[0023] In the above structure, by setting the structure of steel wire rope 1 3, steel wire rope 2 6, and positioning block 15, the positioning block 15 is lowered by winding the steel wire rope 2 6, so that the positioning block 15 pulls the rotating rod 4 to rotate, and there is no need for the user to manually intervene in the form of adding weights, thereby achieving the effect of automatically adjusting the vertical surface pressure of the soil, thereby improving the practicality of the equipment.

[0024] In a preferred embodiment, the positioning block 15 is made of galvanized iron metal, and the outer wall of the positioning block 15 is slidably connected to the inner wall of the slide groove 11 .

[0025] In the above structure, the galvanized iron metal has the characteristics of hardness and wear resistance, which can effectively reduce the wear of the positioning block 15 during the lifting process, thereby extending the service life of the positioning block 15. At the same time, the galvanized iron metal also has the characteristic of low cost, so as to reduce the production cost of the equipment.

[0026] In a preferred embodiment: a control console and a pressure sensor are respectively provided on the outer wall of the body 1, and the control console is respectively electrically connected to the motor 9, the pressure spring 13 and the pressure sensor.

[0027] In the above structure, by setting up a pressure sensor and a control console structure, the pressure sensor is used to sense the pressure data on the vertical surface of the soil, thereby facilitating the user to read detailed data, and the control console enables the user to adjust the pressure, thereby simplifying the operation process of the device and further improving the practicability of the device.

[0028] In a preferred embodiment, the top of the pressure spring 13 contacts the bottom of the slider 14 , and a detection platform is provided on the top of the body 1 .

[0029] In the above structure, by setting up the pressure spring 13 structure, the pressure sensor can sense the pressure on the soil by utilizing the compressive force of the pressure spring 13, thereby making it easy for the user to read specific data and also making it easy for the user to adjust the data size of the pressure value.

[0030] In a preferred embodiment, the number of the straight cylinders 2 is four, and the four straight cylinders 2 are evenly distributed along the top of the support plate 7 .

[0031] In the above structure, through the setting of four straight cylinders 2 structures, in the prior art, it is necessary to prepare four soil samples for direct shear test at the same time to ensure the accuracy of the test results. Through the four straight cylinders 2, the user can perform direct shear operations on four samples, and also perform the test in a way of automatically adjusting the pressure size, which further improves the user's testing efficiency of soil samples.

[0032] Working principle: After assembling the equipment, the user can place the sample on the main body 1, and then use the motor 9 to drive the take-up wheel 10 to rotate, so that the wire rope 2 6 is wound due to the rotation of the take-up wheel 10. At this time, the shortening of the wire rope 2 6 will pull the positioning block 15 downward, so that the rotating rod 4 is pulled by the cross beam 5 to rotate. This method has the same effect as adding weights manually to adjust the vertical surface pressure of the soil, but the automatic adjustment method is more efficient than the existing technology.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
