Detailed Implementation
[0022] like Figures 1-4As shown, this utility model provides a technical solution: a construction equipment for asphalt concrete core wall dams in plateau areas, including a base 1, a fixing frame 2 fixedly installed on the top of the base 1, a mixing tank 3 fixedly installed on the top of the base 1, a conveying pipe 4 fixedly connected to one end of the mixing tank 3, a pump body 5 fixedly connected to the other end of the conveying pipe 4, a pump body 5 fixedly installed on the top of the base 1, a feeding pipe 6 fixedly connected to the feeding pipe 6, the feeding pipe 6 passing through the fixing frame 2 and fixedly connected to the fixing frame 2, a motor 7 fixedly installed at the bottom of the base 1, the output shaft of the motor 7 fixedly connected to the bottom of a stirring rod 8, and the stirring rod 8 connected to the inner wall of the mixing tank 3. The mixing tank 3 is equipped with a control component 9, which includes a triangular plate 91, a slide bar 92, a support block 93, and a mixing component 94. When the cam 944 rotates, it will abut against the tangential surface of the support block 93. When the tangential surface of the support block 93 is abutted, the slide bar 92 fixed to the surface of the support block 93 can slide the triangular plate 91 at the bottom of the fixed plate 942. Since the cam 944 abuts against the support block 93 intermittently, the two sets of triangular plates 91 can move laterally alternately, pushing the material on one side to the other side, thereby forcing the formation of a transverse convection circulation, enhancing the mixing effect, and avoiding the occurrence of dead zones in the mixing.
[0023] A sliding rod 92 is fixedly mounted on the top of the triangular plate 91, and a support block 93 is fixedly mounted on the top of the sliding rod 92. The front end of the support block 93 is triangular in shape. When the cross-section of the support block 93 is in contact with the sliding rod 92, the sliding rod 92 fixed to the surface of the support block 93 can drive the triangular plate 91 to move synchronously. The mixing component 94 includes a crossbar 941, which passes through the sliding rod 92 and is slidably connected to it. The crossbar 941 is fixedly mounted on the inner wall of the fixing plate 942, which is fixedly mounted on the inner wall of the mixing tank 3. The crossbar 941 ensures the stability of the sliding rod 92 during movement. The inner wall of the fixing plate 942 is fixedly connected to one end of a spring 943, and the other end of the spring 943 is fixedly mounted on the side of the sliding rod 92. When the sliding rod 92 is not in hand, it can spring up under the action of the spring 943. The top of the fixed plate 942 is rotatably connected to the bottom of the cam 944, and the bottom of the cam 944 is fixedly connected to the top of the stirring rod 8. The stirring rod 8 passes through the fixed plate 942 and is rotatably connected to it. When the stirring rod 8 rotates on the top of the fixed plate 942, the cam 944 fixed to the top of the stirring rod 8 will rotate synchronously. The mixing tank 3 is penetrated by the pressure rod 945 and slidably connected to it. The arc surface of the pressure rod 945 is fixedly connected to one end of the second spring 946, and the other end of the second spring 946 is fixedly installed on the outer wall of the mixing tank 3. When the pressure rod 945 is no longer resisted, it can spring up under the action of the second spring 946. An arc ring 947 is fixedly installed on the side of the pressure rod 945, and a knocking block 948 is fixedly installed on the inner wall of the arc ring 947. When the pressure rod 945 springs up, the arc ring 947 fixed on the surface of the pressure rod 945 can drive the knocking block 948 to spring up synchronously, striking the outer wall of the mixing tank 3.
[0024] In this invention, when constructing an asphalt concrete core wall dam in a high-altitude area, asphalt, aggregate, and mineral powder are placed into a mixing tank 3. After placement, the motor 7 at the bottom of the base 1 is started. The output shaft of the motor 7 drives the stirring rod 8 to rotate. As the stirring rod 8 rotates, it agitates the asphalt. During the rotation of the stirring rod 8, the cam 944 fixed at the top of the stirring rod 8 rotates synchronously on the top of the fixed plate 942. When the cam 944 rotates, it abuts against the tangential surface of the support block 93. When the tangential surface of the support block 93 is abutted, the sliding rod 92 fixed on the surface of the support block 93 can slide the triangular plate 91 at the bottom of the fixed plate 942. Since the cam 944 abuts against the support block 93 intermittently, the two sets of triangular plates 91 can move laterally alternately, thereby agitating the asphalt. Material on one side is pushed to the other, thus forcing a transverse convection circulation, enhancing the mixing effect and avoiding the occurrence of dead zones in the mixing. During the opening of the triangular plate 91, it will contact the surface of the pressure rod 945. When the pressure rod 945 is contacted, the arc ring 947 fixed on the surface of the pressure rod 945 will move away from the outer wall of the mixing tank 3. When the pressure rod 945 is no longer contacted, the pressure rod 945 will drive the arc ring 947 to bounce up under the action of the spring 946. When the arc ring 947 bounces up, the knocking block 948 fixed on the inner wall of the arc ring 947 can intermittently knock on the outer wall of the mixing tank 3. The mechanical vibration generated by the knocking will be transmitted to the interior of the asphalt material through the tank wall, causing the air bubbles to be subjected to high-frequency impact force, float up and break. After mixing, the pump body 5 and the conveying pipe 4 will extract the asphalt material and send it out through the feeding pipe 6 for construction.
[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
