Description

Technical Field

[0001] This utility model relates to the field of road construction equipment technology, specifically to an intelligent control epoxy asphalt mixing and spreading integrated equipment. Background Technology

[0002] Epoxy asphalt mixing and spreading technology is widely used in road construction and maintenance, especially in high-traffic areas and under special climatic conditions, to improve road service life and performance. Existing epoxy asphalt mixing and spreading equipment typically employs a step-by-step operation, that is, first mixing the epoxy asphalt, and then spreading it evenly on the road surface using spreading equipment.

[0003] Existing epoxy asphalt spreading equipment is divided into two main categories: spreading trucks and small spreading machines. Spreading trucks are mainly used for spraying epoxy asphalt on large road surfaces, while small spreading machines are mainly used for spraying asphalt on small road surfaces and in narrow areas. Small spreading machines are typically equipped with a small-capacity hopper for loading epoxy asphalt. The material is manually poured into the hopper, and then a pump supplies the epoxy asphalt from the hopper to the spreading gun, which is then manually operated for spreading.

[0004] This type of small spreader, due to its small material hopper and limited machine size, requires manual labor or a separate mixing device to mix the epoxy asphalt raw material before pouring the mixed epoxy asphalt into the material hopper. This results in a time-consuming and inefficient step-by-step operation. Secondly, parameter control during mixing and spreading is unstable and easily affected by the external environment and operator skills, leading to uncontrollable quality. In addition, most existing equipment relies on manual operation.

[0005] Therefore, it is necessary to invent an intelligent control epoxy asphalt mixing and spreading integrated equipment to solve the above problems. Utility Model Content

[0016] As a preferred embodiment of this utility model, the top of the mixing bucket is covered with a bucket lid, and a motor is fixedly installed at the middle of the top of the bucket lid. The output end of the motor passes through the bottom of the bucket lid and is connected to the stirring paddle inside the mixing bucket. A feed pipe is installed on one side of the top of the bucket lid.

[0017] As a preferred embodiment of this utility model, a discharge pipe is installed on one side of the lower part of the collection box. The discharge pipe is connected to the input port of the No. 2 conveying pump through a conduit. The output port of the No. 2 conveying pump is connected to a spray gun through a conduit.

[0018] As a preferred embodiment of this utility model, the input end of the No. 1 conveying pump is connected to the raw material barrel through a conduit, and the output end of the No. 1 conveying pump is connected to the feed pipe at the top of the barrel lid through a conduit.

It is especially suitable for continuous repair or small and medium-sized construction scenarios.

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0035] This utility model provides, for example Figure 1-6 The intelligent control epoxy asphalt mixing and spreading integrated equipment shown includes a frame 1, a mixing tank 2 and a collection box 3. The mixing tank 2 is equipped with a mixing paddle 9. The back of the frame 1 is equipped with a control box 14. The bottom of the mixing tank 2 is equipped with an opening and closing mechanism 4.

[0036] In this embodiment, the main support structure of the frame 1 is equipped with casters at the bottom and a handle 15 at the rear. The size of the frame 1 is suitable for operation in confined spaces, allowing it to access areas inaccessible to traditional spreading vehicles. Its omnidirectional casters at the bottom support turning on the spot, and combined with the handle 15, it can be easily operated by a single person, making it suitable for repair work requiring frequent relocation. The frame 1 integrates components such as the mixing tank 2, the collection bin 3, and the conveying pump. Through structural optimization, it ensures the stability of the equipment's center of gravity during travel and operation, avoiding the risk of tipping over.

[0037] The opening and closing mechanism 4 includes:

[0038] A sealing cap 41 is located below the bottom of the mixing tank 2, and connectors 43 are fixedly installed on both sides of the sealing cap 41.

[0039] Cylinder 42 is vertical and is movably installed on the lower side of the outside of the mixing tank 2;

[0040] At least one raw material bucket 13 is placed above the frame 1 and on one side of the collection box 3. A first conveying pump 11 and a second conveying pump 12 are fixedly installed above the frame 1 and on the other side of the collection box 3, respectively.

[0041] The mixing tank 2 is equipped with at least two viscosity sensors 7 inside, a No. 1 level gauge 5 is installed on the lower side of the outside of the mixing tank 2, and a No. 2 level gauge 6 is installed on the top side of the collection box 3.

[0042] In this embodiment, the epoxy asphalt content in the aggregate bin 3 is detected by a second level gauge 6. When the level is lower than a set value, epoxy asphalt can be replenished in the aggregate bin 3 in a timely manner. The detection of the epoxy asphalt content in the aggregate bin 3 by the second level gauge 6 transmits a signal to the controller in the control box 14. The control box 14 then controls the opening and closing mechanism 4 to open the sealing cover 41 at the bottom of the mixing tank 2, allowing the mixed raw materials in the mixing tank 2 to be directly fed into the aggregate bin 3 through the discharge port 23. The aggregate bin 3 has a volume twice that of the mixing tank 2, capable of storing all the adhesive liquid from a single mixing, preventing interruption of the supply during the spreading process due to the discharge of the mixing tank 2, ensuring stable output flow from the spray gun, and improving spreading uniformity.

[0043] Then, the content of raw materials that have been mixed in the mixing tank 2 is detected by the No. 1 level gauge 5. When it is detected that the epoxy asphalt in the mixing tank 2 has been discharged, the controller in the control box 14 drives the opening and closing mechanism 4 to close, so that the sealing cover 41 is closed again at the bottom discharge port 23 of the mixing tank 2.

[0044] Furthermore, in the above technical solution, a protruding liquid level chamber 24 is provided on the side of the mixing tank 2 near the bottom. The liquid level chamber 24 is connected to the interior of the mixing tank 2. The first liquid level gauge 5 is fixedly installed on the top of the liquid level chamber 24, and the probe of the first liquid level gauge 5 is located inside the liquid level chamber 24.

[0045] In this embodiment, since a stirring paddle 9 is installed inside the mixing tank 2, if the probe of the first level gauge 5 were directly placed near the inner wall of the mixing tank 2, the size of the stirring paddle 9 would need to be reduced, thus affecting the mixing effect. Therefore, a raised level chamber 24 is separately installed at the bottom of the mixing tank 2, which can accommodate the position of the probe of the first level gauge 5 without changing the size of the stirring paddle 9. It also allows for timely measurement of the epoxy asphalt content within the mixing tank 2.

[0046] Furthermore, in the above technical solution, the collection box 3 is fixedly installed above the frame 1, the bottom of the mixing bucket 2 is fixedly installed on the top of the collection box 3 by a bracket, the bottom of the mixing bucket 2 is provided with a discharge port 23 in the middle position, the top of the collection box 3 is provided with an opening 31 in the middle position, and the discharge port 23 corresponds to the opening 31.

[0047] In this embodiment, since the opening 31 at the top of the collection box 3 corresponds to the discharge port 23 at the bottom of the mixing tank 2, when the opening and closing mechanism 4 controls the sealing cover 41 to open the discharge port 23 at the bottom of the mixing tank 2, the mixed raw materials in the mixing tank 2 can directly fall into the collection box 3 through the opening 31. Furthermore, the opening and closing mechanism 4 employs intelligent control for opening and closing, making unloading more convenient and faster, saving time.

[0048] Furthermore, in the above technical solution, the upper end of the sealing cover 41 is adapted to the discharge port 23, the protrusion at the upper end of the sealing cover 41 can be inserted into the discharge port 23, the connecting piece 43 on one side of the sealing cover 41 is rotatably connected to the shaft on one side of the outer wall of the mixing tank 2, and the connecting piece 43 on the other side of the sealing cover 41 is rotatably connected to the lower part of the output end of the cylinder 42.

[0049] In this embodiment, the protrusion at the upper end of the sealing cap 41 precisely fits with the inner wall of the discharge port 23 to form a seal. The cylinder 42 then extends and retracts via a solenoid valve, its stroke matching the opening height of the discharge port 23. The cylinder 42 drives the sealing cap 41 to open or close smoothly, and the discharge speed can be adjusted by air pressure (e.g., slow opening to avoid splashing of adhesive). When the sealing cap 41 is closed, the protrusion of the sealing cap 41 and the discharge port 23 form a mechanical lock, which, together with the silicone sealing ring, prevents leakage. A logic to prevent discharge during stirring can also be set in the controller. If the motor 8 is running, the cylinder 42 cannot trigger the opening, preventing adhesive splashing during discharge when the stirring paddle 9 is not stopped, thus improving operational safety.

[0050] Furthermore, in the above technical solution, a lid 21 is installed on the top of the mixing tank 2, and a motor 8 is fixedly installed in the middle of the top of the lid 21. The output end of the motor 8 passes through the bottom of the lid 21 and is connected to the stirring paddle 9 inside the mixing tank 2. A feed pipe 22 is installed on one side of the top of the lid 21.

[0051] Furthermore, in the above technical solution, a discharge pipe 32 is installed on one side below the collection box 3. The discharge pipe 32 is connected to the input port of the second conveying pump 12 through a conduit. The output port of the second conveying pump 12 is connected to a spreading spray gun through a conduit.

[0052] Furthermore, in the above technical solution, the input end of the first conveying pump 11 is connected to the raw material barrel 13 through a conduit, and the output end of the first conveying pump 11 is connected to the feed pipe 22 at the top of the barrel cover 21 through a conduit.

[0053] Furthermore, in the above technical solution, a handle frame 15 is fixedly installed on the back of the frame 1, and a control box 14 is fixedly installed on the outside of the handle frame 15. The control box 14 is equipped with a controller and other components inside, and a control switch is installed outside. At least two viscosity sensors 7 are fixedly installed on the upper and lower sides of the inner wall of one side of the mixing tank 2, respectively.

[0054] In this embodiment, the raw materials are directly transported from the raw material tank 13 to the empty mixing tank 2 via the first delivery pump 11, eliminating the need for manual emptying and preventing the high-temperature adhesive from contacting the operators. When the raw material content in the mixing tank 2 reaches a specified value, the motor 8 is immediately started. The motor 8 drives the stirring paddle 9 to thoroughly and evenly stir the material in the mixing tank 2, ensuring sufficient viscosity. The stirring paddle 9 achieves thorough stirring throughout the entire tank, and in conjunction with the upper and lower dual viscosity sensors 7 (detecting the viscosity of the adhesive at different heights), when the viscosity difference between the upper and lower layers is less than a given value, the controller in the control box 14 determines that mixing is complete and automatically stops the machine, avoiding excessive stirring and energy waste.

[0055] Furthermore, in the above technical solution, the first transfer pump 11, the second transfer pump 12, the cylinder 42, the first level gauge 5, the second level gauge 6, the viscosity sensor 7, and the motor 8 are electrically connected to the controller, receiver, and other components in the control box 14 through wires.

[0056] In this embodiment, the control box 14 integrates a controller (PLC or microcontroller), relays, frequency converters, and other components internally. Externally, it features a touchscreen or push-button switches to display information such as mixing status, spreading parameters, and fault alarms. Operators only need to set target parameters (such as mixing time, spreading amount, and stirring speed) in the control box 14, and the equipment automatically completes the entire process of feeding, mixing, unloading, and spreading, reducing manual intervention. When the viscosity sensor 7 malfunctions, the level gauge fails, or the pump is overloaded, the control box 14 will issue a real-time alarm and display fault codes, guiding operators to quickly troubleshoot the problem.

[0057] The intelligent control epoxy asphalt mixing and spreading integrated equipment provided by this utility model operates as follows:

[0058] Epoxy asphalt components A and B are loaded into the raw material tank 13 located above the frame 1, and connected to the input of the first conveying pump 11 via conduits. The output of the first conveying pump 11 is then connected to the feed pipe 22 via conduits. The operator then selects start in the control box 14. The controller automatically starts the first conveying pump 11 based on the remaining capacity of the mixing tank 2 detected by the first level gauge 5. The first conveying pump 11 delivers the epoxy asphalt raw material from the raw material tank 13 to the mixing tank 2 through the feed pipe 22. When the first conveying pump 11 delivers the set amount of raw material, it automatically stops to prevent overflow.

[0059] After the material is fed in, motor 8 automatically starts, driving the stirring paddle 9 to stir the raw materials in mixing tank 2. The stirring paddle 9 adopts a ribbon or blade design to ensure thorough mixing throughout the tank. At this time, the upper and lower dual viscosity sensors 7 in mixing tank 2 detect the viscosity of the adhesive at different heights in real time and transmit the data to the control box 14. When the viscosity difference between the upper and lower layers is less than the set threshold and the overall viscosity reaches the target value, the controller determines that mixing is complete and automatically stops motor 8.

[0060] After mixing, level gauge 6 monitors the epoxy asphalt level in aggregate bin 3 in real time. When the level drops below the set value, level gauge 6 sends a signal to control box 14. Upon receiving the signal, control box 14 first confirms that motor 8 has stopped operating (based on the logic of prohibiting unloading during mixing), and then drives cylinder 42 to operate. Cylinder 42 drives the sealing cover 41 to flip and unfold through connector 43, opening the discharge port 23 at the bottom of mixing tank 2. The mixed epoxy asphalt falls directly into aggregate bin 3 through discharge port 23 and opening 31 at the top of aggregate bin 3. When level gauge 5 detects that the epoxy asphalt in mixing tank 2 has been completely discharged, control box 14 drives cylinder 42 to retract, causing sealing cover 41 to close discharge port 23 again to prevent leakage.

[0061] The epoxy asphalt in aggregate bin 3 is conveyed to the second conveying pump 12 through discharge pipe 32. The second conveying pump 12 precisely adjusts the output flow rate according to the spreading amount and spray gun movement speed set in control box 14. The operator holds the spreading spray gun and moves along the road surface to perform the spreading operation. The gun barrel is equipped with a heating layer to ensure that the adhesive maintains a suitable temperature during the spreading process and avoids condensation and blockage. During the spreading process, if the liquid level in aggregate bin 3 is too low, the equipment automatically triggers the unloading process of mixing tank 2 to ensure continuous material supply, maintain a stable spray gun output flow rate, and improve the uniformity of spreading.

[0062] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
