A kind of preparation method of asphalt concrete

Abstract

The invention discloses a method for preparing asphalt concrete, which comprises the following steps: step 1: adding heated asphalt into the shell, and controlling the rotating shaft to drive a stirring rod located in the shell to stir the asphalt; step 2: putting crushed stones in the into the screen mechanism, and control the push plate to move to the left to push the crushed stones into the screen, and the push rod to move to the left to connect the pulley assembly connected with the screen mechanism to the rotating shaft; step 3: continue to control the extension of the electric push rod out, the electric push rod drives the push plate to push the large stones blocked on the screen to the left, and the large stones are broken by the rotating gravel knife, and then fall into the asphalt through the screen; Step 4: when the broken stones After all the screening is completed, the push rod controls the screen mechanism to stop rotating; Step 5: Continue to control the stirring rod to fully stir the asphalt mixed with crushed stones. After five minutes, the preparation of asphalt concrete is completed; the preparation method of this asphalt concrete is not only easy to operate , and can quickly realize the preparation of asphalt concrete.

Description

technical field [0001] The invention belongs to the technical field of asphalt concrete, in particular to a preparation method of asphalt concrete. Background technique [0002] Asphalt concrete is a mixture made by mixing gravel or crushed gravel, stone chips or sand, mineral powder, etc., with a certain proportion of road asphalt materials under strictly controlled conditions. Asphalt concrete is often used for paving roads. It has the advantages of economy and safety, smooth surface, no joints, no dust, easy cleaning, fast construction progress, and high strength. There are following problems in the preparation of asphalt concrete in the prior art: 1. When the existing equipment is preparing and processing asphalt concrete, it cannot effectively screen the crushed stone material, resulting in the mixing of finished materials. Blocky crushed stones affect the subsequent processing and use of finished materials; 2. Asphalt concrete preparation equipment that can be screene...

Problems solved by technology

There are following problems in the preparation of asphalt concrete in the prior art: 1. When the existing equipment is preparing and processing asphalt concrete, it cannot effectively screen the crushed stone material, resulting in the mixing of finished materials. Blocky crushed stones affect the subsequent processing and use of finished materials; 2. Asphalt concrete preparation equipment that can be screened usually has the problem of crushed stones blocking the screen holes, resulting in low filtration efficiency and affecting the production period of asphalt concrete
