Description

Technical Field

[0001] This utility model relates to the field of asphalt mixture technology, specifically to an asphalt mixture density measuring device. Background Technology

[0002] When determining the density of asphalt mixtures, specific density measuring equipment is required, and the internal temperature of the equipment must be kept constant during the measurement. However, existing asphalt mixture density measuring equipment typically operates at room temperature, making it difficult to measure the density of asphalt mixtures under constant temperature, which affects the measurement results. Therefore, designing a new asphalt mixture density measuring device is very important. For example:

[0003] A device for measuring the density of asphalt mixture, disclosed in Chinese Patent Publication No. CN217638529U, includes: a support base, a weighing sensor disposed at the center of the upper part of the support base, a weighing frame disposed above the weighing sensor, a support frame plate disposed above the weighing frame, and a weighing container disposed inside the support frame plate. This invention adds the mixture to the weighing container through a discharge pipe, then controls an electric valve to quantitatively add the mixture into the weighing container. An electric push rod then moves a scraper to scrape the surface of the weighing container, removing excess mixture from the top of the container, thus ensuring greater accuracy in volume measurement. The density of the mixture is then determined by weighing using the weighing sensor. A protective cover isolates the device from the external environment during discharge, preventing external air from affecting the measurement and thus the accuracy of the results.

[0004] However, the above-mentioned existing technical solutions have the following drawbacks: they are not convenient for asphalt mixture density measuring equipment to carry out input experiments on asphalt mixtures of different volumes, and at the same time, they are not convenient for temperature control function during asphalt mixture density measurement. Therefore, this utility model provides an asphalt mixture density measuring equipment to solve the above-mentioned problems. Utility Model Content
