Description

Technical Field

[0001] The utility model relates to the technical field of soil sample moisture content test equipment, in particular to an automatic cleaning device for a soil sample weighing box, which is mainly used for cleaning and drying the soil sample weighing box in a soil sample moisture content test. Background Art

[0002] The moisture content test is an experiment to measure the moisture content of coarse-grained soil, fine-grained soil, organic soil and frozen soil. The determination of soil moisture content is an important part of geotechnical testing. When testing the moisture content of existing soil samples, a representative sample or a sample from a ring cutter is placed in a weighing box to weigh the wet soil mass. The box lid is then opened and the weighing box is placed in an oven. After drying at a constant temperature to a constant weight, the box is removed and placed in a drying container to cool to room temperature to obtain the dry weight of the soil sample. The moisture content is then calculated based on the wet weight and dry weight of the soil sample.

[0003] In the process of measuring the moisture content of soil samples, weighing boxes are essential test containers. In general, multiple sets of data need to be measured during moisture content tests to ensure the accuracy of the calculations. Therefore, multiple weighing boxes are used for each moisture content test. In traditional methods, after the soil moisture content test, these weighing boxes are manually cleaned and then placed in a drying oven for drying and storage to ensure that the weighing boxes are clean and dry the next time they are used, without affecting the accuracy of the test. Sometimes, to ensure the accuracy of the test, the weighing boxes are also cleaned and dried a second time before the test. Since a large number of weighing boxes are used in each test, and the weighing boxes are generally cylindrical and not large in size, manual cleaning is cumbersome. The entire process is not only time-consuming and labor-intensive, but also has the problem of incomplete cleaning. Especially when the humidity of wet soil is relatively high, or when measuring sticky soil, it is difficult to wipe the weighing boxes clean after drying, which can lead to incomplete cleaning and inaccurate test results. In addition, since the weighing box consists of two parts, the box body and the box cover, errors are easily introduced during manual cleaning, and the disassembly process can easily lead to the problem of incorrect matching between the box body and the box cover, affecting the test results.

[0004] Therefore, it is very necessary to develop an automated cleaning and drying system. Summary of the Invention

After cleaning is completed, the control lift 4 drives the box body fixed plate 100 and the box cover fixed plate 104 to a position higher than the ultrasonic cleaning tank 4 slots, and again controls the spray mechanism to rinse the box body fixed plate 100, the box cover fixed plate 104 and the weighing box 9 fixed in the pan body for a second time;

[0051] S8. After rinsing is complete, turn on the hot air blower 16 and adjust the temperature. Control the drying mechanism to blow hot air toward the rinsed box fixing plate 100, the box cover fixing plate 104, and the weighing box 9 fixed in the plate body, thereby quickly drying the cleaned weighing box. After drying is complete, the lifting frame 4 is moved to the top of the waste soil collection box 3 by the transmission motor 10 and the transmission screw 11.

[0052] S9. Lower the box body fixing plate 100 to between the two sets of first electric telescopic rods 600. Control the two sets of first electric telescopic rods 600 to extend and engage the holes on both sides of the box body fixing plate 100. Control each rotating telescopic rod of the lifting frame 4 to continue rotating to 45 degrees. At this time, the first connecting block 401 is no longer engaged with the box body fixing plate 100, and the second connecting block 402 remains engaged with the box cover fixing plate 104. Then, control the third section of the three-section telescopic clamping tube to retract and disengage from the box body fixing plate 100. At this time, the box body fixing plate 100 is fixed between the two first electric telescopic rods 600. The first rotating motor 601 is again used to drive the box body fixing plate 100 to flip 180 degrees so that the plate opening faces upward.

[0053] S10. Control the second section of the three-section telescopic clamping tube of the lifting frame 4 to extend and drive the box cover fixing plate 104 to cover the box body fixing plate 100, and cut off the power to the electromagnetic suction cup of the box cover fixing plate 104, so that the box cover of the weighing box 9 is not connected to the box cover fixing plate 104, and then rotate the three-section telescopic clamping tube to the original position, and then control the second section and the third section of the tube to retract, so that the rotating three-section telescopic clamping tube is separated from the box body fixing plate 100 and the box cover fixing plate 104, and the cleaned box body fixing plate 100 and the box cover fixing plate 104 can be taken out.
