Description

Technical Field

[0001] The utility model relates to the technical field of engineering detection, in particular to a sample drying device for sand and gravel screening experiments. Background Technique

[0002] In the research of fields such as geology, water conservancy, and civil engineering, the analysis of the particle composition, particle size distribution and other characteristics of sand and gravel samples is indispensable. When sand and gravel are classified and screened, a large amount of soil on their surfaces will be screened into the sand and gravel with smaller particle sizes, thus affecting the determination of the content of each level of sand and gravel.

[0003] The Chinese patent discloses a sample water washing and drying device for sand and gravel screening tests (authorization announcement number CN216522657U). In this patented technology, the setting of the conveying mechanism can convey the sand and gravel to be cleaned, so that the sand and gravel can be washed and dried in sequence. The setting of the cleaning mechanism can wash the sand and gravel conveyed by the conveying mechanism. When the sand and gravel are conveyed to the first filter pipe, they pass through the cleaning mechanism for cleaning. Subsequently, the surface impurities and moisture after cleaning can be collected through the collecting pipe. The setting of the drying mechanism can perform wind drying on the sand and gravel after water washing. The set second servo motor can drive the turning plate to rotate, so that the sand and gravel after water washing can be turned over, so that the air drying fan can fully dry the sand and gravel.

[0004] However, it has certain drawbacks: when the conveying mechanism conveys the sand and gravel, the cleaning mechanism cleans the sand and gravel synchronously. The sand and gravel on the outside are easy to come into contact with water for cleaning, while the sand and gravel on the inside cannot fully come into contact with water. These dusts that are not washed away by water but only come into contact with less water will only adhere more firmly to the surface of the sand and gravel. Coupled with the fact that the conveying rods in the conveying mechanism can only convey the sand and gravel and are not convenient for dispersing the sand and gravel, the sand and gravel on the inside cannot fully come into contact with water, so the sand and gravel cannot be efficiently cleaned.
