Description

Technical Field

[0001] The invention relates to the technical field of soil sample moisture content test equipment, in particular to an automatic cleaning and drying device for a soil sample moisture content test weighing box, which is mainly used for cleaning and drying a 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, take a representative sample or a sample from a ring knife, put it into a weighing box to weigh the wet soil mass, then open the box lid, put the weighing box in an oven, dry it at a constant temperature until it reaches a constant weight, then take it out, put it in a drying container and cool it to room temperature to get the dry weight of the soil sample, and then calculate its moisture content through 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 indispensable test containers, and generally, multiple sets of data need to be measured in the process of moisture content test to ensure the accuracy of calculation, so multiple weighing boxes are used for each moisture content test; in the traditional method, after the soil sample moisture content test is completed, these weighing boxes used for the test are manually cleaned, and after cleaning, they are placed in a drying oven for drying and storage to ensure that the weighing boxes are clean and dry when used next time, which will not affect the accuracy of the test; sometimes, in order to ensure the accuracy of the test, the weighing boxes are also cleaned and dried twice before the test. Since there are a large number of weighing boxes used in each test, and the weighing boxes are generally cylindrical and not large in size, it is troublesome to clean them manually. The whole process is not only time-consuming and laborious, but also has the problem of incomplete cleaning, especially when the humidity of wet soil is relatively high, or when measuring relatively sticky soil, it is difficult to wipe the weighing boxes clean after drying, which will also lead to incomplete cleaning, which may lead to inaccurate test results. In addition, since the weighing box consists of two parts, a box body and a box cover, errors are easily introduced during the manual cleaning process, and the disassembly process is prone to mismatching of 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

[0059] S7. After the cleaning is completed, the lifting frame 4 is controlled to drive the box body fixing plate 100 and the box cover fixing plate 104 to rise to a position higher than the notch of the ultrasonic cleaning tank 4, and the spray mechanism is controlled again to perform a secondary rinse on the box body fixing plate 100, the box cover fixing plate 104 and the weighing box 9 fixed in the plate body;

[0060] S8. After the rinsing is completed, the hot air blower 16 is turned on and the temperature is adjusted, and the drying mechanism is controlled to blow hot air toward the rinsed box body fixing plate 100, the box cover fixing plate 104 and the weighing box 9 fixed in the plate body to quickly dry the cleaned weighing box; after the drying is completed, the lifting frame 4 is driven by the transmission motor 10 and the transmission screw 11 to move to the top of the waste soil collection box 3;

[0061] S9. Lower the box body fixing plate 100 to between the two groups of first electric telescopic rods 600, control the two groups of first electric telescopic rods 600 to stretch out and insert into the holes on both sides of the box body fixing plate 100; control each rotating telescopic rod of the lifting frame 4 to continue to rotate to 45°, at which time the first connecting block 401 is not engaged with the box body fixing plate 100, and the second connecting block 402 is still engaged with the box cover fixing plate 104, and then control the third section of the three-section telescopic clamping tube to shrink and detach from the box body fixing plate 100, at which time the box body fixing plate 100 is fixed between the two first electric telescopic rods 600, and the first rotating motor 601 is used again to drive the box body fixing plate 100 to flip 180° until the plate mouth faces upward;

[0062] 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 shrink, 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, so that the box body fixing plate 100 and the box cover fixing plate 104 that have been cleaned can be taken out.
