Portable weighing and charging-integrated asphalt mixture mixing device

Abstract

The invention relates to a portable weighing and charging-integrated asphalt mixture mixing device, which comprises a mixing pot with a heating device, a horizontal base and a support skeleton arranged on the base, wherein a weighing and measuring system is arranged on the base; the mixing pot is located on the weighing and measuring system; the support skeleton is provided with a liftable and lowerable mixer; the mixer is located above the mixing pot; a mixing shaft of the mixer is sleeved with a sealing pot cover capable of sealing the mixing pot while mixing and the lower end of the mixing shaft is connected with a mixing blade; and the bottom of the mixing pot is connected with an automatic charging system. The raw materials can be directly weighed through the mixing pot, and the mass loss and the heat loss of raw materials in the transfer process are reduced, so that the dose of the raw materials is more accurate, the test temperature is more accurate, the test accuracy rate is improved, the quality of a prepared test specimen is improved, and asphalt mixture mixing, automatic weighing and charging integration is achieved.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of asphalt mixture mixing equipment, and in particular relates to a portable asphalt mixture mixing device integrating weighing and charging. [0003] 【Background technique】 [0004] With the development of science and technology and the increasing intensity of infrastructure construction, asphalt mixture has become the main road construction material in road engineering. Asphalt mixture is a kind of composite material, mainly composed of asphalt, coarse aggregate, fine aggregate, mineral powder, sometimes mixed with materials such as polymer and fiber for modification. In the laboratory, the raw materials of asphalt mixture are weighed, mixed by mixing equipment, charged, and compacted to form Marshall specimens or rut plate specimens for experimental research, which can more appropriately reflect the road performance of the materials. Among them, the mixing of the mixture is a very important link. During th...

Problems solved by technology

In this process, it will not only cause a certain quality loss of raw materials, but also make the temperature of the raw materials not reach the expected temperature, so that the performance indicators of the Marshall test piece or the rut plate test piece cannot reach the ideal value.

In addition, this series of operations is relatively complicated and the temperature is too high during loading, which is prone to burns. It requires the use of weighing instruments, ovens, etc., which not only consumes time and energy, but also causes waste of energy, which is contrary to the concept of economic and environmental protection. It is highly dependent on other instruments, which reduces the convenience of the test
