[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] A mixing device for self-leveling asphalt construction includes a mixing assembly, which includes a mixing motor 1. A mixing rod 2 is installed at the output end of the mixing motor 1, and a mixing head 3 is installed at the bottom of the mixing rod 2. Two sets of limiting plates 12 are fixedly installed in the middle of the mixing rod 2, and a protective cover 13 is provided between the limiting plates 12. The protective cover 13 is slidably engaged with the mixing rod 2, and a spring 14 is slidably sleeved on the surface of the mixing rod 2. The top of the spring 14 abuts against the upper limiting plate 12, and the bottom of the spring 14 abuts against the protective cover 13.

[0027] By setting up a mixing assembly, the self-leveling asphalt raw material can be mixed evenly. The mixing assembly is powered by a mixing motor 1, which drives the mixing rod 2 and the bottom mixing head 3 connected to the output end to rotate, thereby fully mixing the asphalt raw material and ensuring that the modifier, thickener and other additives are evenly mixed with the asphalt substrate, thus ensuring the construction performance of the self-leveling asphalt. At the same time, the two sets of limiting plates 12 in the middle of the mixing rod 2 limit the sliding range of the protective cover 13. The protective cover 13 can fit against the opening of the mixing container under the elastic action of the spring 14, which not only avoids asphalt splashing during the mixing process, which would cause raw material waste and safety hazards, but also reduces the entry of dust and other impurities into the mixing system and affect the asphalt quality. The elastic support of the spring 14 can also adapt to mixing containers of different heights, improving the flexibility of use.

[0028] It also includes a lifting assembly, which includes a movable seat 4, which is mounted on the surface of the lead screw 5. The lead screw 5 is rotatably mounted inside the middle of the support frame 6. One side of the movable seat 4 is fixedly connected to one side of the mounting frame 7, and the other side of the mounting frame 7 is fixedly connected to the stirring motor 1. The top of the lead screw 5 is connected to the output end of the lifting motor 16. The lifting motor 16 has a self-locking function and is fixedly mounted on the top of the support frame 6. Two sets of guide rods 17 are provided on both sides of the lead screw 5. The guide rods 17 are fixedly connected to the support frame 6. Two sets of guide seats 18 are slidably mounted on the surface of the guide rods 17. The guide seats 18 are fixedly connected to the mounting frame 7. The mounting frame 7 is provided with a fixing ring that matches the shape of the stirring motor 1. The fixing ring is fixed to the outer shell of the stirring motor 1 by screws.

[0029] The lifting assembly is primarily used for stable support and height adjustment of the mixing assembly to adapt to mixing containers of different depths and achieve automated mixing operations. The lifting motor 16 drives the lead screw 5 to rotate, causing the movable seat 4 on the surface of the lead screw 5 to move along the axial direction of the lead screw 5. This, in turn, drives the mixing assembly to rise and fall synchronously via the mounting frame 7 fixed to the movable seat 4, meeting the mixing requirements of asphalt raw materials at different depths. This eliminates the need for manual adjustment of the mixing position, reducing labor intensity. Simultaneously, the guide rods 17 on both sides of the lead screw 5 and the guide seat 18 form a guiding structure, effectively preventing deviation and shaking of the mixing assembly due to uneven force during lifting, ensuring stable operation of the mixing head 3. Furthermore, the lifting motor 16 has a self-locking function, which can stably fix the mixing assembly in any lifting position, further improving the stability and safety of the mixing process.

[0030] It also includes a folding storage component, which includes a pull-out plate 8. The top of one side of the pull-out plate 8 is rotatably connected to the bottom of the support frame 6 via a pivot 9. A slide block 10 is fixedly installed on the bottom of the other side of the pull-out plate 8. The slide block 10 is slidably installed on the surface of the slide rod 11. The slide rod 11 is fixedly installed inside the base 22. A support block 15 for supporting the support frame 6 is fixedly installed at one end of the pull-out plate 8. The support block 15 can support the bottom of the support frame 6 when it is rotated and erected.

[0031] By incorporating a folding storage component, the core function is to facilitate the convenient extension, fixation, and folding storage of the mixing component, significantly improving the equipment's mobility. During operation, the pull-out plate 8 can be pushed along the slide rod 11 inside the base 22 via the bottom slide block 10, extending the pull-out plate 8, the top-connected support frame 6, and the mixing component from the storage space such as the vehicle compartment. The position of the pull-out plate 8 is then fixed by the third fixing screw 21. Subsequently, the support frame 6 is rotated and erected around the pivot 9, supported by the support block 15 and locked by the first fixing screw 19, putting the mixing component into the working state. After operation, the first fixing screw 19 is loosened to fold the support frame 6 flat around the pivot 9, and the support frame 6 is locked by the second fixing screw 20. The third fixing screw 21 is then loosened to retract the pull-out plate 8 into the base 22 and re-fix it, achieving rapid storage of the mixing component. This avoids repeated loading and unloading of equipment during relocation, significantly improving relocation efficiency and reducing the labor intensity of operators.

[0032] A first fixing screw 19 is slidably installed on the middle of one side of the support block 15. The first fixing screw 19 is threadedly connected to the bottom of the support frame 6. The first fixing screw 19 can fix the position of the support frame 6 when it is erected. A second fixing screw 20 is slidably installed on the other end of the pull plate 8. The second fixing screw 20 is threadedly connected to the top of the support frame 6. The second fixing screw 20 can fix the position of the support frame 6 when it is rotated and retracted. The two sides of the base 22 are respectively threadedly connected to two sets of third fixing screws 21. The third fixing screws 21 are slidably engaged with the two sides of one set of slide blocks 10. The two sets of third fixing screws 21 can fix the position of the pull plate 8 when it is extended and retracted, respectively.

[0033] By setting the first fixing screw 19, the second fixing screw 20, and the third fixing screw 21, the state of the folding storage component can be fixed after it is unfolded or folded. The first fixing screw 19 is installed on the support block 15 at one end of the pull-out plate 8. When the support frame 6 in the folding storage component rotates and stands up around the pivot 9, and the support block 15 provides support to the bottom of the support frame 6, the support frame 6 can be firmly fixed by the threaded connection with the bottom of the support frame 6, preventing it from tipping over when the mixing component is working or when the equipment shakes slightly, thus ensuring the stability of the mixing operation. The second fixing screw 20 is installed at the other end of the pull-out plate 8. After the operation is completed, the support frame 6 is folded flat around the pivot 9 and placed flat on the pull-out plate. When the surface is folded, the support frame 6 can be locked onto the pull-out plate 8 by connecting it to the top of the support frame 6 with a thread, preventing the support frame 6 from shaking randomly during the transfer and ensuring the stability of the storage state; the third fixing screw 21 is threaded to both sides of the base 22 and slides with the slide block 10 at the bottom of the pull-out plate 8. When the pull-out plate 8 slides along the slide rod 11 through the slide block 10 to the extended working position or the retracted storage position, tightening the third fixing screw 21 so that it abuts against the slide block 10 can fix the pull-out plate 8 in the extended or retracted state respectively, preventing the pull-out plate 8 from accidentally sliding during operation or extending by itself during the transfer, further ensuring the safety and stability of equipment operation and transfer.

[0034] The device also includes a control panel for controlling the lifting motor 16 and the stirring motor 1. The control panel includes a power management chip, an H-bridge motor drive module, and a current detection circuit. It is equipped with five self-resetting waterproof button groups, including a main power switch (with lock), a start / stop button for the stirring motor 1, a lifting button for the lifting motor 16, and an emergency stop button. It also includes four LED indicator groups, including a power indicator, a stirring operation indicator, a lifting operation indicator, and a fault alarm light. The housing also has a terminal block, which is connected to the lifting motor 16, the stirring motor 1, the main power supply of the equipment, and the current sensor via shielded wires. When the control panel is working, the main control module receives the button operation signals and drives the corresponding motor to operate. The device status is fed back through the indicator lights. When a motor overload is detected, the motor power is automatically cut off and the fault alarm light is triggered to achieve safety protection. The control panel is also connected to the motor and power module inside the main body of the equipment via wires.

[0035] In practical use, after moving the device to the designated position, use screws to fix the base 22 to the carriage of the transport vehicle or other fixed parts. First, loosen the fixing of the slide 10 by the third fixing screws 21 on both sides of the base 22, push the pull plate 8 so that the slide 10 at its bottom slides along the slide rod 11 inside the base 22, and extend the pull plate 8, the support frame 6 connected to the top, and the stirring assembly together from the storage space. After the pull plate 8 extends to the working position, pass the third screw through the slide 10 and connect it to the base 22, and then tighten the third fixing screw 21 to fix the pull plate 8. Then loosen the second fixing screw 20 on the pull plate 8, rotate the support frame 6 around the pivot 9 to stand it up, so that the support block 15 at one end of the pull plate 8 fits against the bottom of the support frame 6 to form a support, and then connect the first fixing screw 19 on the support block 15 to the bottom of the support frame 6 to lock the support frame 6 in the standing state. Then operate the main power switch on the control panel. Turn on the power supply to the equipment. The power indicator light will illuminate. Depending on the depth of the mixing container, press the up or down button on the lifting motor 16. The lifting motor 16 drives the lead screw 5 to rotate, which in turn drives the mixing components connected to the moving seat 4 and the mounting frame 7 to rise and fall synchronously until the mixing head 3 is lowered to the appropriate mixing depth. Finally, press the start / stop button on the mixing motor 1. The mixing motor 1 drives the mixing rod 2 and the mixing head 3 to rotate and mix the asphalt raw materials. During the mixing process, the protective cover 13 is in contact with the container opening under the elastic action of the spring 14 to prevent asphalt from splashing and impurities from entering. After the operation is completed, first press the stop button on the mixing motor 1, then raise the mixing components to the high position using the lifting button. Then, loosen the first fixing screw 19, fold the support frame 6 around the pivot 9 and lay it flat on the surface of the pull-out plate 8. Lock the support frame 6 with the second fixing screw 20, loosen the third fixing screw 21, retract the pull-out plate 8 into the base 22 and fix it again. Turn off the main power switch to complete the operation.
