Description

Technical Field

[0001] This utility model relates to the field of asphalt mixing and processing technology, and in particular to an asphalt mixture mixer. Background Technology

[0002] Asphalt mixture, a composite material, is composed of asphalt, coarse aggregate, fine aggregate, and mineral powder, and is an important material for paving asphalt roads. An asphalt mixture mixer is a specialized piece of equipment used to mix asphalt, coarse aggregate, fine aggregate, and mineral powder in a specific ratio to produce asphalt mixtures that meet engineering requirements.

[0003] In the prior art, Chinese patent document CN212426634U discloses an asphalt mixture mixing machine. The asphalt mixture mixing machine adopts a lifting mechanism to connect with the mixing pot, so that the mixing pot is raised. After the mixing work is completed, the rotation of the mixing pot is not restricted by the base, and the angle of rotation is increased, making it easier to pour out the asphalt mixture.

[0004] However, the aforementioned asphalt mixing plant has the problem of inconvenient cleaning of the mixing pot. When cleaning the mixing pot, water usually needs to be added into the mixing pot by hand with a water hose. If the water flow rate of the hose is not properly controlled, the water in the mixing pot will splash out of the mixing pot, making the production working environment worse. At the same time, the existing mixing pot does not have a discharge port at the bottom, making it inconvenient to drain the cleaning water from the mixing pot.

[0005] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0006] The present invention provides an asphalt mixture mixer, which aims to solve the problem of inconvenient cleaning of the mixing pot in existing asphalt mixture mixers.

[0043] Please see Figures 1 to 6As shown, this utility model provides an asphalt mixture mixer, including a base 1, a lifting mechanism 2, a mixing pot 3, a top seat 4, a drive motor 5, a rotating rod 6, a mixing assembly (not shown in the attached diagram), and an annular cover 7. The lifting mechanism 2 is existing technology (it can also be achieved by a motor driving a lead screw to rotate, thus raising and lowering the mixing pot 3), and is located on both sides of the mixing pot 3. The mixing pot 3 is positioned above the base 1 and connected to the lifting mechanism 2, so the lifting mechanism 2 can drive the mixing pot 3 to rise and fall. To heat and mix the asphalt mixture inside the mixing pot 3, a jacket is provided between the inner and outer walls of the mixing pot 3. Heat-conducting oil is injected into the jacket, and by heating the heat-conducting oil, its heat is transferred to the mixing pot 3, thereby heating the asphalt mixture. The top seat 4 is fixedly positioned above the mixing pot 3, and its interior is used to mount the drive motor 5. The rotating rod 6 is located below the top seat 4 and is connected to the output shaft of the drive motor 5. The mixing assembly is detachably mounted on the lower end of the rotating rod 6. When the drive motor 5 is working, it can drive the rotating rod 6 and the mixing assembly to rotate, thereby mixing the asphalt mixture in the mixing pot 3. The annular cover is fixed to the bottom of the top seat 4 and surrounds the rotating rod 6. Thus, when the mixing pot 3 is raised, the annular cover 7 can cover the mixing pot 3, thereby closing the opening above the mixing pot 3.

[0044] like Figure 1 , Figure 2 as well as Figure 6 As shown, the asphalt mixture mixer further includes a water spraying assembly 8, a first water supply pipe 9, a water pump 10, and a water storage tank 11. The water spraying assembly 8 is located inside the top seat 4, and its spray nozzle 811 extends into the annular cover 7. When cleaning the mixing pot 3 is required, the mixing pot 3 rises to a position where the annular cover 7 can cover it. At this time, there is no need to manually add water to the mixing pot 3 using a water hose; the water spraying assembly 8 sprays water downwards, allowing the cleaning water to fall into the mixing pot 3. Furthermore, the mixing action of the assembly automatically cleans the mixing pot 3, making cleaning more convenient. Also, because the annular cover 7 prevents water from splashing out of the mixing pot 3, the working environment around the asphalt mixture mixer will not deteriorate during cleaning.

[0045] To supply water to the water spray assembly 8, the first water supply pipe 9 is detachably connected to the water spray assembly 8, the output end of the water pump 10 is connected to the first water supply pipe 9, and the outlet of the water storage tank 11 is connected to the input end of the water pump 10. When the water pump 10 is working, the cleaning water in the water storage tank 11 is transported to the water spray assembly 8 through the first delivery pipe under the suction force of the water pump 10.

[0046] like Figure 1As shown, optionally, the water spray assembly 8 includes multiple inclined water spray pipes 81 and a second water supply pipe 82 simultaneously connected to the multiple water spray pipes 81. When the mixing pot 3 rises to a position where the annular cover 7 can cover the mixing pot 3, the water spray pipes 81 can spray water towards the inner wall of the mixing pot 3, so that the material adsorbed on the inner wall of the mixing pot 3 can be separated from the inner wall of the mixing pot 3 by the water flow, thereby improving the cleaning effect of the mixing pot 3. The second water supply pipe 82 is detachably connected to the first water supply pipe 9, for example, by means of a flange connector, so that when the water spray assembly 8 experiences pipe blockage, it is easy to disassemble and clean the water spray assembly 8.

[0047] like Figure 1 As shown, optionally, the outer wall of the water storage tank 11 is provided with an observation window 12, and the observation window 12 is provided with water level scale lines. By providing an observation window 12 on the outer wall of the water storage tank 11 and using the water level scale lines, the operator can easily observe the water level changes in the water storage tank 11, which can prevent excessive water from being added to the mixing pot 3.

[0048] like Figure 4 and Figure 5 As shown, optionally, the asphalt mixture mixer also includes a cleaning component 13; the cleaning component 13 is detachably mounted on the lower end of the rotating rod 6, and is used to rotate and clean the inner wall of the mixing pot 3. Since both the mixing component and the cleaning component 13 are detachably mounted on the lower end of the rotating rod 6, when it is necessary to further improve the cleaning effect of the mixing pot 3, the operator can remove the mixing component located at the lower end of the rotating rod 6 and replace it with the cleaning component 13, thereby further improving the cleaning effect of the mixing pot 3 by rotating the inner wall of the mixing pot 3 through the cleaning component 13.

[0049] like Figure 4 and Figure 5 As shown, optionally, the cleaning component 13 includes a sleeve 131, a first connecting rod 132, and a first brush body 133.

[0050] The sleeve 131 is fitted onto the lower end of the rotating rod 6, facilitating the disassembly and installation of the cleaning component 13. When the rotating rod 6 rotates, the sleeve 131 rotates along with it, allowing the cleaning component 13 to rotate for cleaning operations. The first connecting rod is horizontally positioned, and the first connecting rod 132 is connected to the sleeve 131. The first brush body 133 is vertically positioned and detachably connected to the first connecting rod 132. When the mixing pot 3 rises to a position where the annular cover 7 can cover the mixing pot 3, the cleaning component 13 is located inside the mixing pot 3, and the first brush body 133 contacts the inner wall of the mixing pot 3. The rotating first brush body 133 cleans the inner wall of the mixing pot 3, effectively removing material adsorbed on the inner wall of the mixing pot 3.

[0051] like Figure 4 and Figure 5 As shown, optionally, the cleaning assembly 13 further includes a second connecting rod 134 and a second brush body 135. The second connecting rod 134 is horizontally positioned below the first connecting rod 132 and is fixedly connected to the sleeve 131. The second brush body 135 is inclined and detachably connected to the second connecting rod 134, and is used to clean the bottom inner wall of the mixing pot 3. Since the bottom of the mixing pot 3 is usually inverted conical in the prior art, by setting the second connecting rod 134 below the first connecting rod 132 and connecting the second connecting rod 134 to the inclined second brush body 135, the bottom of the inverted conical mixing pot 3 can be effectively cleaned by the second brush body 135.

[0052] It should be noted that this utility model does not limit the number of the first brush body 133 and the second brush body 135, and there can be more than two of the first brush body 133 and the second brush body 135.

[0053] like Figure 1 and Figure 3 As shown, optionally, the upper end of the sleeve 131 is provided with two corresponding pin holes; the two pin holes are provided with pins 14; the pins 14 are inserted into the rotating rod 6, and both ends of the pins 14 are located on the outside of the sleeve 131 and are provided with external threads, so that the cleaning component 13 and the rotating rod 6 can be fixedly connected by fitting a locking nut 15 connected to the external threads on the pins 14.

[0054] It is understood that the stirring assembly can also be fixedly connected to the rotating rod 6 in the manner described above.

[0055] like Figure 1 As shown, optionally, a discharge pipe 16 is provided at the bottom of the mixing pot 3; the discharge pipe 16 is equipped with a water control valve 17, and a drain hose 18 is detachably connected to the discharge pipe 16. By opening a discharge port at the bottom of the mixing pot 3 and connecting the discharge port to the discharge pipe 16, it is convenient to discharge the cleaning water and the washed material inside the mixing pot 3 to the outside of the mixing pot 3. It is understood that a pump is needed to drain the water from the drain hose 18.

[0056] like Figure 4 As shown, optionally, a bracket 19 is also provided between the top seat 4 and the base 1. The bracket 19 is equipped with a limit switch 20 for detecting the support members on both sides of the mixing pot 3, thereby controlling the upward stroke of the mixing pot 3 and avoiding excessive compression between the annular cover 7 and the mixing pot 3.

[0057] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
