Description

Technical Field

[0001] The utility model belongs to the technical field of asphalt mixers, and in particular relates to an asphalt mixer which is convenient for heating asphalt. Background Art

[0002] Asphalt mixing equipment, commonly known as asphalt mixer or asphalt slurry mixer, is a special equipment used for preparing asphalt mixture. In road engineering, airport construction, parking lot paving and other construction, asphalt mixture is a material made by mixing asphalt, mineral materials (such as crushed stone or gravel) and fillers (such as mineral powder) in a certain proportion. It has good adhesion, water resistance and certain elasticity, and is widely used in road paving.

[0003] There is a common technical difficulty in the use of existing asphalt mixers, that is, the operation of uniformly heating the asphalt being mixed inside is not convenient enough. This problem leads to uneven temperature distribution of the asphalt during the mixing process, which may affect the quality of the asphalt mixture. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an asphalt mixing machine that is convenient for heating asphalt, comprising a barrel body, a barrel cover is snap-connected to the inner upper end of the barrel body, a support structure is fixedly connected to the upper surface of the barrel cover, a driving motor is arranged at the upper end of the support structure, a stirring shaft is transmission-connected to the output end of the driving motor, a stirring blade is fixedly connected to the side surface of the stirring shaft, connecting rods are fixedly connected to the four corners of the lower surface of the support structure, a lifting groove is provided on the inner surface of the connecting rod, a micro motor is fixedly connected to the inner bottom end of the lifting groove, a threaded screw is transmission-connected to the output end of the micro motor, a lifting block is threadedly connected to the surface of the threaded screw, and an electric heating rod is fixedly connected to one side surface of the lifting block.

[0006] Preferably, four electric heating rods are provided, and the four electric heating rods are all arranged inside the barrel body.

[0007] Preferably, the lower end of the barrel body is fixedly connected to a base.

[0008] Preferably, a transparent pipe is fixedly connected through the side surface of the barrel body.

[0009] Preferably, a discharge port is installed through the lower end of one side surface of the barrel body.

[0010] Preferably, a valve is installed on the discharge port.

[0011] Preferably, an emergency stop button is installed on the upper end of the side surface of the barrel body.

[0012] Compared with the prior art, the utility model provides an asphalt mixing machine which is convenient for heating asphalt and has the following beneficial effects:

[0013] 1. The utility model is provided with a connecting rod and a lifting block and other structures. When the asphalt is stirred by the stirring blade, the threaded screw is driven to rotate by the micro motor, so that the lifting block drives the inner electric heating rod to rise and fall inside the barrel, thereby heating the asphalt at different depths and positions more evenly, effectively avoiding a common technical problem of the existing asphalt mixing machine during use, that is, the operation of uniformly heating the asphalt being stirred inside is not convenient enough, which leads to uneven temperature distribution of the asphalt during the mixing process, which may affect the quality of the asphalt mixture;

[0014] 2. The utility model provides a transparent pipe. Before the asphalt raw material is passed into the barrel for mixing, since the barrel is not made of transparent material, outsiders cannot clearly know the amount of asphalt in the barrel. The lower end of the transparent pipe is connected to the inside of the barrel, and the amount of asphalt in the barrel can be directly displayed through the transparent pipe, thereby making the asphalt mixing machine more practical to use.

[0027] In the utility model, preferably, a transparent pipe 5 is fixedly connected to the side surface of the barrel body 1. Through the transparent pipe 5, before the asphalt raw material is passed into the barrel body 1 for mixing, since the barrel body 1 is not made of transparent material, outsiders cannot clearly know the amount of asphalt inside the barrel body 1. Through the lower end of the transparent pipe 5 and the inside of the barrel body 1, the amount of asphalt inside the barrel body 1 can be directly displayed through the transparent pipe 5, thereby making the asphalt mixing machine more practical to use.

[0031] The working principle and use process of the utility model are as follows: when in use, the asphalt raw material is passed into the barrel body 1, and the amount of the asphalt raw material is observed through the transparent pipe 5 to ensure that the asphalt raw material in the barrel body 1 is sufficient; turn on the power, start the drive motor 8, drive the stirring shaft 9 to rotate, and stir the asphalt in the barrel body 1 through the stirring blade 10; at the same time, start the micro motor 13, drive the threaded screw 14 to rotate, so that the lifting block 15 drives the inner electric heating rod 16 to rise and fall inside the barrel body 1. Four electric heating rods 16 are evenly distributed in the barrel body 1, and the asphalt at different depths and different positions is heated more evenly; during the mixing process, the temperature of the asphalt in the barrel body 1 is monitored in real time through the temperature sensor to ensure that the temperature distribution of the asphalt during the mixing process is uniform; if the amount of asphalt in the barrel body 1 needs to be adjusted, it can be controlled through the valve 4 on the discharge port 3. When the asphalt volume reaches the ideal state, close valve 4 and continue to mix and heat. If an emergency occurs during the mixing and heating process, press the emergency stop button on the upper side of the barrel 1 to stop all equipment to ensure safe operation. When the asphalt is mixed evenly and the temperature reaches the set requirements, turn off the power and stop all equipment. Take out the mixed asphalt mixture through the discharge port 3 for subsequent use or storage. After completing the mixing task, close valve 4, clean the asphalt residue in the barrel 1, clean and maintain the equipment, and prepare for the next use.

[0032] Through the above working process, the asphalt mixer provided by the utility model that is convenient for heating asphalt can achieve uniform heating of the internal asphalt while mixing the asphalt, effectively improving the quality of the asphalt mixture, and at the same time is easy to operate, safe and reliable.
