Description

Technical Field

[0001] This utility model relates to the technical field of roadbed filler mixing equipment, and in particular to a uniform mixing device for highway roadbed filler. Background Technology

[0002] The roadbed of a highway is the foundation of the road surface. It is an earthwork structure formed by excavation or filling. The raw materials required for the roadbed filling are generally lime, fly ash, crushed stone and cement. Before the roadbed filling is carried out, the required raw materials need to be mixed. At this time, the raw materials need to be stirred by mixing equipment.

[0003] There is a roadbed material mixing device for highways (authorization announcement number: CN217629270U), which drives a rotating rod to rotate by starting a drive motor. The rotating rod drives the stirring fan blades and stirring rod to stir the roadbed material in the material mixing tank. Although it can mix the roadbed material in the material mixing tank, it is not convenient to quickly discharge the mixed roadbed material after the mixing is completed, which is inconvenient to use. Therefore, this utility model is proposed to solve the above problems. Utility Model Content

A conveying drive mechanism is provided on the conveying cylinder. A feed hopper is provided on one outer wall of the conveying cylinder. A lifting drive mechanism for the conveying cylinder is provided on the top side of the annular mixing tank. Two mixing mechanisms for corresponding mixing chambers are provided on the top side of the support frame.

[0007] Preferably, the conveying chamber in the annular mixing tank is located in the middle of the two mixing chambers, and the conveying chamber is connected to the two mixing chambers to facilitate the counter-current circulation of the roadbed filler in the conveying chamber and the two mixing chambers.

One end of the first drive rod is fixedly installed on the output shaft of the first motor. The other end of the first drive rod extends into the conveying cylinder and is fixedly installed with an auger. The outer contact surface of the auger rotates and fits against the inner wall of the conveying cylinder. Through the conveying drive mechanism, the roadbed filler is conveyed upward from the bottom of the conveying cylinder by the rotation of the auger, and then slides down through the two top openings on the conveying cylinder into the two mixing chambers of the annular mixing tank.

[0020] Furthermore, the conveying chamber 4 inside the annular mixing tank 2 is located in the middle of the two mixing chambers 3. The conveying chamber 4 is connected to the two mixing chambers 3, which facilitates the counter-current circulation of the roadbed filler in the conveying chamber 4 and the two mixing chambers 3.

[0021] Specifically, the two top openings 7 on the conveying cylinder 6 are connected to the two stirring chambers 3, and the two bottom openings 8 on the conveying cylinder 6 are connected to the two stirring chambers 3.

One end of the first drive rod 10 is fixedly installed on the output shaft of the first motor 9. The other end of the first drive rod 10 extends into the conveying cylinder 6 and is fixedly installed with the auger 11. The outer contact surface of the auger 11 rotates and fits against the inner wall of the conveying cylinder 6. Through the conveying drive mechanism, the roadbed filler is conveyed upward from the bottom of the conveying cylinder 6 by the rotation of the auger 11, and then slides down through the two top openings 7 on the conveying cylinder 6 into the two mixing chambers 3 of the annular mixing tank 2.

[0023] Specifically, the lifting drive mechanism includes a U-shaped mounting frame 13, a hydraulic rod 14, and a rod plate 15. The U-shaped mounting frame 13 is fixedly installed on the top side of the annular mixing tank 2. The hydraulic rod 14 is fixedly installed on the inner wall of the U-shaped mounting frame 13. The rod plate 15 is fixedly installed on the output end of the hydraulic rod 14. The bottom end of the rod plate 15 is fixedly connected to the top side of the conveying cylinder 6.

[0025] In use: When mixing highway subgrade filler, the subgrade filler to be mixed is poured into the conveying cylinder 6 inside the annular mixing tank 2 through the feed hopper 12. The first motor 9 is started, causing the first drive rod 10 to drive the auger 11 to rotate inside the conveying cylinder 6. The rotation of the auger 11 conveys the subgrade filler upwards from the bottom of the conveying cylinder 6, and then it slides down through the two top openings 7 into the two mixing chambers 3 of the annular mixing tank 2. Simultaneously, two second motors 16 are started, causing the two second drive rods 17 to synchronously drive the two sets of mixing paddles 18 to rotate, thus mixing the subgrade filler that has slid down into the mixing chambers 3. After mixing, the subgrade filler slides down into the two bottom openings 8 of the conveying cylinder 6, and then is again conveyed upwards by the rotating auger 11 for a second mixing. This cycle is repeated to achieve the mixing of the subgrade filler in the annular mixing tank 2. The two mixing chambers 3 and the conveying chamber 4 are used for counter-cyclic mixing to achieve uniform and thorough mixing of the roadbed filler. After the roadbed filler in the annular mixing tank 2 is mixed, the first motor 9 and the two second motors 16 are turned off, and the hydraulic rod 14 is started to push the conveying cylinder 6 downward, so that the bottom end of the conveying cylinder 6 extends out of the annular mixing tank 2 until the extended part reaches the middle position of the height of the two bottom openings 8 on the conveying cylinder 6. The mixed roadbed filler flows out through the two openings below the two bottom openings 8 on the conveying cylinder 6. By starting the first motor 9, the first drive rod 10 drives the auger 11 to rotate in the opposite direction, accelerating the downward conveying and discharge of the mixed roadbed filler in the annular mixing tank 2. The operation is simple and fast, and it has the characteristics of thorough and uniform mixing of roadbed filler and rapid discharge, which improves the practicality of the highway roadbed filler mixing device.
