Technical Field
[0001] This utility model relates to the field of construction engineering, and in particular to an asphalt mixing device for construction engineering that is easy to clean. Background Technology
[0002] Asphalt is a black or dark brown viscous liquid or semi-solid, mainly composed of hydrocarbons, and is a residue from petroleum distillation. It possesses waterproof, adhesive, and durable properties, and is widely used in paving (asphalt concrete), building waterproofing, and corrosion protection projects. Based on its source, it can be divided into natural asphalt and petroleum asphalt. It needs to be softened by heating before use and hardens upon cooling. Its properties are significantly affected by temperature, and environmentally friendly asphalt is becoming a development trend.
[0003] In construction projects, asphalt mixing is a crucial step in preventing premature asphalt solidification and ensuring its normal use. However, after mixing asphalt, the mixing rods of the asphalt mixing device have a large amount of residual asphalt on their surface, which is difficult to remove from the motor output end and clean. In addition, some mixing devices are equipped with internal wall cleaning scrapers, but it is difficult to replace the scrapers in a timely and efficient manner after they wear out. This greatly reduces the cleaning efficiency of the device and thus affects the construction progress of the entire construction project.
[0004] Therefore, those skilled in the art have provided an asphalt mixing device for construction projects that is easy to clean, in order to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an easy-to-clean asphalt mixing device for construction projects. The device fixes one end of the mixing rod to the mounting plate, passes through the through groove to the hook rod, and rotates the adjusting rod 90 degrees. Then, the mounting plate is pulled down so that the hook rod engages with the slot on the mounting plate, thus completing the initial fixation of the mixing rod and the servo motor. Then, the locking plate at one end of the hook rod is twisted 90 degrees to abut against the pad block. Rotating the knob moves the rotating ring and the locking block down to engage with the locking plate. This completes the quick fixation and replacement of the mixing rod, improving the cleaning efficiency of the device.
[0006] To achieve the above objectives, this utility model provides the following technical solution: An easy-to-clean asphalt mixing device for construction projects includes a tank, a support, a controller, a tank cover, a protective shell, a servo motor, and a mixing rod. The output end of the servo motor is fixedly connected to a quick disassembly and assembly mechanism, and one end of the outer wall of the mixing rod is provided with a convenient replacement mechanism. The quick-assembly and disassembly mechanism includes a threaded rod, one end of which is fixedly connected to a connecting rod. Sliding grooves are formed on both sides of the outer wall of the connecting rod. A knob is fitted onto the outer wall of the threaded rod. A rotating ring is fixedly connected to one side of the knob. Two locking blocks are slidably connected to one side of the outer wall of the rotating ring. An adjusting rod is rotatably connected to one end of the connecting rod. Hook rods are fixedly connected to both sides of the outer wall of the adjusting rod. A locking plate is hinged to one end of the hook rod. A mounting plate is engaged with one end of the hook rod. A through groove is formed in the middle of one side of the mounting plate. Locking grooves are formed at both ends of one side of the mounting plate. Two pads are formed in the middle of one side of the mounting plate. Through the above technical solution, the device achieves initial fixation of the stirring rod and servo motor by passing the mounting plate fixed at one end of the stirring rod through the through groove, rotating the adjusting rod 90 degrees, and then pulling down the mounting plate to engage the hook rod with the slot on the mounting plate. Then, the locking plate at one end of the hook rod is twisted 90 degrees to abut against the pad, and the knob is rotated to move the rotating ring and locking block down to engage with the locking plate. This completes the quick fixation and replacement of the stirring rod, improving the cleaning efficiency of the device.
[0007] Furthermore, the convenient replacement mechanism includes two fixing blocks. A threaded rod is rotatably connected to the middle of one end face of the fixing block. An adjusting plate is fixedly connected to one end of the outer wall of the threaded rod. A slider is sleeved on the outer wall of the threaded rod. Slide rails are fixedly connected to both sides of the outer wall of the stirring rod. A scraper is slidably connected to one side of the outer wall of the slide rail. Through the above technical solution, the device is initially fixed by sliding the scraper into the bottom of the slide rail. Then, the adjustment disc is turned so that the slider slides under the limit of the upper end of the stirring rod. One end of the slider slides to the upper end of one side of the slide rail and passes through its outer wall to form a locking connection with the upper end of one side of the scraper. This facilitates the replacement and maintenance of the scraper and improves the cleaning efficiency of the device.
[0008] Furthermore, a bracket is fixedly connected to the lower end of the tank, a controller is provided on one side of the outer wall of the tank, a tank cover is provided at the upper end of the tank, a protective shell is fixedly connected to the middle of the upper surface of the tank cover, a servo motor is provided inside the protective shell, and a stirring rod is fixedly connected to the middle of the lower surface of the mounting plate. Through the above technical solution, the bracket is used to support the tank, the controller controls the overall operation of the device, the tank cover is used to seal the tank to prevent foreign objects from entering during mixing, the protective shell protects the servo motor, and the servo motor drives the mixing rod to stir the asphalt.
[0009] Furthermore, a locking block is slidably connected to one side of the outer wall of the slide groove, and one end of the locking block is engaged with the lower end of one side face of the locking plate. Through the above technical solution, the sliding of the card block is more stable and the slide groove can play a limiting and fixing role. The engagement of the card block and the card plate allows the mounting plate to be completely fixed with the hook rod, thereby completing the fixing of the stirring rod and the servo motor.
[0010] Furthermore, the hook rod and the slot form an engaging connection, and the opening area of the through groove is consistent with the area of the cross-section of the adjusting rod and the hook rod; With the above technical solution, the hook rod can easily pass through the mounting plate and form a snap-fit connection with it.
[0011] Furthermore, a threaded rod is fixedly connected to the output end of the servo motor; Through the above technical solution, the servo motor drives the threaded rod, which in turn drives the mounting plate and the stirring rod.
[0012] Furthermore, one end of the threaded rod is rotatably connected to the upper end of one side face of the slide rail, and the lower end of the slider is slidably connected to the upper end face of the stirring rod. Through the above technical solution, the threaded rod can have a more stable fulcrum of rotation, thereby driving the slider to slide stably under the limit of the upper end face of the stirring rod.
[0013] Furthermore, one end of the slider passes through the upper end face of one side of the slide rail and forms a locking connection with the upper end of the one side of the scraper. With the above technical solution, the scraper can be fixed on the slide rail and is not easy to loosen.
[0014] This utility model has the following beneficial effects: 1. This utility model proposes an easy-to-clean asphalt mixing device for construction projects.
