Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for test sieves, specifically a portable test sieve placement device. Background Technology

[0002] In the testing and inspection of building materials, test sieves are key tools for screening aggregates such as sand and gravel. They must be operated in accordance with specifications such as "Test Procedure for Hydraulic Concrete" SL / T 352-2020, "Sand for Construction" GB / T 14684-2022, and "Pebbles and Crushed Stone for Construction" GB / T14685-2022.

[0003] While the test sieves currently used in laboratories can meet basic testing requirements, the following problems exist in actual operation, especially in the storage, management, and retrieval of test sieves: 1. There is a lack of standardized placement for test sieves after use. Testers often pile them up randomly on the ground or workbench, which not only takes up space but also easily leads to wear on the sieve holes or damage to the sieve body, affecting the accuracy of subsequent tests.

[0004] 2. Some testing sites may use a method of stacking test sieves in sequence. However, in some routine tests, it is necessary to frequently combine test sieves of specific specifications. For example, in the coarse aggregate mud content test, test sieves with 1.25mm and 0.08mm mesh sizes need to be frequently used. The process of taking out and putting back the test sieves stacked in sequence is cumbersome. If a certain sieve needs to be taken out, all the sieves above it must be taken out in sequence. The operation efficiency is low and the workload of the test personnel is increased. Summary of the Invention
