Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete aggregate detection, in particular to a concrete aggregate grading and impurity rapid detection integrated device and method. BACKGROUND

[0002] The concrete aggregate grading refers to the combination of different particle sizes of aggregates in concrete, which has an important influence on the workability, strength, durability and other properties of concrete.

[0003] The coarse aggregate grading refers to the distribution of different particle sizes of coarse aggregates (rock particles with a particle size greater than 4.75mm, commonly known as gravel, pebbles, etc.) in concrete, which plays a key role in the performance of concrete. The particle size is continuously graded from large to small, and each level of aggregate has an appropriate proportion. In the 5-40mm continuous grading gravel, the gravel in the particle size range of 5-10mm, 10-20mm, 20-30mm, 30-40mm, etc. has a certain content. The voids between the aggregate particles of such grading can be effectively filled by smaller particles, the mixed concrete has good workability and is not prone to segregation, and is widely used in ordinary concrete engineering.

[0004] The prior art such as the utility model with publication number CN216718119U discloses a concrete aggregate grading detection device, which comprises a screening cylinder composed of a plurality of unit structures connected vertically and end to end, and a fixing support for fixing the screening cylinder. The unit structure comprises an external cylinder, which comprises a vertical section and an inclined section below. A first buffer plate inclined downward is arranged on the inner wall of one side of the vertical section, and a second buffer plate inclined downward is arranged reversely below the opposite side of the first buffer plate. The device further comprises a circular screen, which is arranged in the inclined section through a sliding groove on the top inner wall of the inclined section. The device can replace the shaking screen machine to vibrate and sieve the aggregate by periodically extending and retracting the electric push rod and cooperating with the vibration motor. After the vibration time reaches the standard, the remaining unscreened aggregate on the circular screen is pushed out from the discharge port by retracting the electric push rod, replacing the existing manual material separation step, effectively shortening the detection time, improving the detection efficiency, and reducing the labor cost.

[0005] Although the above-mentioned patent replaces the existing manual material separation step, manual measurement of the content of each level of aggregate is still required in the subsequent detection process. Moreover, the impurities contained in the coarse aggregate are ignored during the detection process. The existing coarse aggregate often contains soil and mud blocks. When the soil and mud blocks adhere to the aggregate, the "apparent particle size" of the aggregate will increase, resulting in that the mass ratio of each level of aggregate after screening does not match the actual grading, and the mass of the impurities will be included in the total mass of the aggregate, causing the grading data to be artificially high and affecting the overall detection structure.

[0006] Therefore, the concrete aggregate grading and impurity rapid detection integrated device and method are provided. SUMMARY
