Technical Field
[0001] This utility model relates to the field of asphalt mixing technology, specifically to a fiber asphalt mixing device. Background Technology
[0002] Nano-montmorillonite-bagasse fiber asphalt is a composite material in which nano-montmorillonite and bagasse fiber are added as modifiers to asphalt to improve its performance. This type of modified asphalt aims to combine the advantages of nano-montmorillonite and bagasse fiber to enhance the mechanical properties, durability, and environmental adaptability of conventional road paving asphalt.
[0003] When using nano-montmorillonite and bagasse fiber as asphalt raw materials, an asphalt mixer is also required to uniformly mix them with other raw materials. Most existing asphalt mixers use a motor to drive a drive gear, which in turn meshes with a moving gear ring containing a mixing drum to rotate and ensure uniform mixing inside the mixing drum.
[0004] However, since asphalt mixers are mostly installed outdoors, their working parts are easily clogged by debris in the air or impurities in the asphalt raw materials. This not only affects the normal mixing and blending effect of the asphalt raw materials, but may also lead to mechanical failures such as broken teeth or chipped teeth in the working parts, resulting in inconvenience and safety hazards. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a fiber asphalt mixing device that can automatically lubricate the transmission gears and gear rings periodically.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a fiber asphalt mixing device, comprising a support frame, a mixer body mounted on the support frame, a rotating motor mounted on one side of the support frame, a transmission gear mounted on the output shaft of the rotating motor, and a gear ring mounted outside the mixer body and meshing with the transmission gear. A protective shell is fixedly connected to the middle of the support frame. The protective shell is fitted and rotatably connected to the outside of the mixer body, and both the transmission gear and the gear ring are located inside the protective shell. An oil storage component is connected to the bottom surface of the protective shell. One end of the oil storage component is connected to a diversion component, and the other end of the diversion component is connected to a pumping mechanism. The other end of the pumping mechanism penetrates into the inside of the protective shell.
[0007] Furthermore, a protective cavity is provided inside the protective shell, and an oil leakage port is provided through the bottom surface of the protective cavity. The transmission gear and gear ring are both located inside the protective cavity, and the oil leakage port is connected to the oil storage component.
[0008] Furthermore, the oil storage assembly includes an oil storage tank and a refueling pipe. The upper surface of the oil storage tank has a waste oil chamber that communicates with the oil leak port, and the lower end of the oil storage tank has a clean oil chamber. One end of the refueling pipe is fixedly connected to the lower end of the oil storage tank, and a sealing cap is threaded onto the outer wall of the refueling pipe. The refueling pipe communicates with the clean oil chamber, and the end of the oil storage tank away from the refueling pipe is connected to the diversion assembly.
[0009] Furthermore, the diversion assembly includes a three-way pipe, two oil suction pipes, and two solenoid valves. One end of each of the two oil suction pipes is fixedly connected to the oil storage tank, and the two oil suction pipes are respectively connected to the waste oil chamber and the clean oil chamber. The other end of each of the two oil suction pipes is fixedly connected to one end of the three-way pipe, and the other end of the three-way pipe is connected to the pumping mechanism. The two solenoid valves are respectively installed inside the two oil suction pipes. Both the two oil suction pipes and the three-way pipe are connected to the inside of the pumping mechanism.
[0010] Furthermore, the pumping mechanism includes an oil pump, an oil outlet pipe, and an oil inlet pipe. The outer wall of the oil pump is fixedly connected to the bracket. The input end of the oil pump is fixedly connected to one end of the oil inlet pipe, and the other end of the oil inlet pipe is fixedly connected to a tee pipe. The output end of the oil pump is fixedly connected to one end of the oil outlet pipe, and the other end of the oil outlet pipe extends into the interior of the protective shell. The tee pipe, the oil outlet pipe, the oil pump, and the oil inlet pipe are all connected to the interior of the protective shell.
[0011] Furthermore, the end of the oil outlet pipe located inside the protective casing points towards the meshing point of the transmission gear and the gear ring.
[0012] Furthermore, two observation ports are opened at one end of the oil storage tank, which are respectively connected to the waste oil chamber and the clean oil chamber. Both observation ports are equipped with transparent glass, and scale lines are set on the transparent glass.
[0013] Furthermore, liquid level sensors are fixedly connected to the lower ends of the inner walls of both the waste oil chamber and the clean oil chamber.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] This fiber-reinforced asphalt mixing device effectively isolates impurities from the external environment (such as dust in the air and debris from asphalt raw materials) by setting up a protective shell to enclose the transmission gears and gear rings. This prevents the meshing parts from being blocked by debris, significantly reduces the risk of mechanical failures such as broken teeth or chipped teeth in the transmission gears and gear rings, and improves the stability and safety of the equipment operation.
[0016] This fiber asphalt mixing device can collect excess lubricating oil (waste oil) that naturally slides down the protective chamber due to gravity or centrifugal force by connecting the oil drain at the bottom of the protective shell to the waste oil chamber of the oil storage tank, thus realizing waste oil recycling. The waste oil in the waste oil chamber is preferentially extracted by the diversion component for circulation lubrication. When the waste oil is insufficient, it is switched to the clean oil chamber to extract new oil, thereby reducing lubricating oil waste and lowering the cost of use.
[0017] The fiber-reinforced asphalt mixing device allows for direct observation of the oil levels in the waste oil chamber and clean oil chamber through the observation port (with transparent glass and scale lines) of the oil storage tank. The level sensor can monitor the oil level in real time and issue a warning when the oil level is insufficient, preventing the inability to replenish lubricating oil in time due to lack of oil, which could lead to dry grinding or excessive wear of gears, thus further ensuring the reliability of the equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Please see Figures 1-4 The fiber asphalt mixing device includes a support 1, a mixer body 2 mounted on the support 1, a rotary motor 3 mounted on one side of the support 1, a transmission gear 15 mounted on the output shaft of the rotary motor 3, and a gear ring 9 mounted on the outside of the mixer body 2 and meshing with the transmission gear 15. A protective shell 6 is fixedly connected to the middle of the support 1. The protective shell 6 is fitted and rotatably connected to the outside of the mixer body 2, and the transmission gear 15 and the gear ring 9 are both located inside the protective shell 6. An oil storage component is connected to the bottom surface of the protective shell 6. One end of the oil storage component is connected to a diversion component, and the other end of the diversion component is connected to a pumping mechanism. The other end of the pumping mechanism penetrates into the inside of the protective shell 6.
[0025] like Figures 1 to 4As shown, after a period of use, the fiber asphalt mixing device of this utility model can periodically start the pumping mechanism to prevent the transmission gear 15 and gear ring 9 from aggravating wear due to lack of lubrication. After the pumping mechanism is started, its input end will draw lubricating oil from the oil storage component through the diversion component, and then automatically pump the lubricating oil to the protective shell 6 through the output end to lubricate the transmission gear 15 and gear ring 9, thereby reducing the wear rate.
[0026] As a preferred embodiment of this utility model, a protective cavity 601 is provided inside the protective shell 6, and an oil leakage port 602 is provided through the bottom surface of the protective cavity 601. The transmission gear 15 and the gear ring 9 are both located inside the protective cavity 601, and the oil leakage port 602 is connected to the oil storage component.
[0027] More specifically, by setting up a protective cavity 601 and an oil drain 602, excess lubricating oil inside the protective shell 6 can be collected, reducing lubricating oil waste.
[0028] As a preferred embodiment of this utility model, the oil storage assembly includes an oil storage tank 7 and a refueling pipe 8. The upper surface of the oil storage tank 7 is provided with a waste oil chamber 702 that communicates with the oil drain port 602. The lower end of the oil storage tank 7 is provided with a clean oil chamber 703. One end of the refueling pipe 8 is fixedly connected to the lower end of the oil storage tank 7. A sealing cap is threaded onto the outer wall of the refueling pipe 8. The refueling pipe 8 communicates with the clean oil chamber 703. The end of the oil storage tank 7 away from the refueling pipe 8 is connected to a diversion assembly.
[0029] More specifically, when the amount of clean oil in the clean oil chamber 703 of the oil reservoir 7 is insufficient and lubricating oil needs to be added, simply turn the sealing cap, open the filling pipe 8, and then add clean lubricating oil into the clean oil chamber 703 through the filling pipe 8. It is convenient and quick.
[0030] Furthermore, when adding lubricating oil, the entire protective cavity 601 of the protective shell 6 will not be filled with lubricating oil. It is only necessary to ensure that there is a certain amount of lubricating oil at the meshing point of the transmission gear 15 and the gear ring 9 (i.e., the surface of the transmission gear 15 and the gear ring 9). Therefore, when adding lubricating oil, it is only necessary to control the main body 2 of the mixer to rotate one or more times so that the lubricating oil is evenly coated on the surface of the transmission gear 15 and the gear ring 9. As the transmission gear 15 and the gear ring 9 move, the lubricating oil on the surface of the transmission gear 15 and the gear ring 9 will also slide off by gravity or centrifugal force. At this time, the excess lubricating oil inside the protective shell 6 will automatically flow into the waste oil chamber 702 through the oil drain port 602 for collection. When it is time for the next refueling, lubricating oil can be drawn from the waste oil chamber 702 first for refueling, thus saving resources.
[0031] As a preferred embodiment of this utility model, the diversion assembly includes a three-way pipe 11, two oil suction pipes 12, and two solenoid valves 13. One end of each of the two oil suction pipes 12 is fixedly connected to the oil storage tank 7, and the two oil suction pipes 12 are respectively connected to the waste oil chamber 702 and the clean oil chamber 703. The other end of each of the two oil suction pipes 12 is fixedly connected to one or both ends of the three-way pipe 11. The other end of the three-way pipe 11 is connected to the pumping mechanism. The two solenoid valves 13 are respectively installed inside the two oil suction pipes 12. The two oil suction pipes 12 and the three-way pipe 11 are all connected to the inside of the pumping mechanism.
[0032] More specifically, when lubricating oil needs to be added, the pumping mechanism will draw lubricating oil from the inside of the two oil suction pipes 12 through the three-way pipe 11 (either individually or in sequence, no specific limitation is made). Then, lubricating oil can be drawn from the waste oil chamber 702 and the clean oil chamber 703. The drawn lubricating oil can then be pumped by the pumping mechanism to the meshing point of the transmission gear 15 and the gear ring 9 inside the protective shell 6 for lubrication.
[0033] In addition, see details Figure 4 When the pumping mechanism extracts lubricating oil, it prioritizes extracting the waste oil in the waste oil chamber 702. During extraction, the solenoid valve 13 on the suction pipe 12 corresponding to the waste oil chamber 702 is opened, and the waste oil can be extracted by the pumping mechanism. If the waste oil is insufficient, clean oil needs to be extracted from the clean oil chamber 703. At this time, the solenoid valve 13 on the suction pipe 12 corresponding to the waste oil chamber 702 is closed, and the solenoid valve 13 corresponding to the clean oil chamber 703 is opened to extract the clean oil.
[0034] In a preferred embodiment of this utility model, the pumping mechanism includes an oil pump 4, an oil outlet pipe 5, and an oil inlet pipe 10. The outer wall of the oil pump 4 is fixedly connected to the bracket 1. The input end of the oil pump 4 is fixedly connected to one end of the oil inlet pipe 10, and the other end of the oil inlet pipe 10 is fixedly connected to a three-way pipe 11. The output end of the oil pump 4 is fixedly connected to one end of the oil outlet pipe 5, and the other end of the oil outlet pipe 5 extends into the interior of the protective shell 6. The three-way pipe 11, the oil outlet pipe 5, the oil pump 4, and the oil inlet pipe 10 are all connected to the interior of the protective shell 6. The end of the oil outlet pipe 5 located inside the protective shell 6 points towards the meshing point of the transmission gear 15 and the gear ring 9.
[0035] More specifically, when it is necessary to extract lubricating oil, simply turn on the oil pump 4. The input end of the oil pump 4 can extract lubricating oil from the inside of the oil inlet pipe 10 and the three-way pipe 11. Then, the oil pump 4 will transport the extracted lubricating oil back to the inside of the protective shell 6 through the oil outlet pipe 5.
[0036] As a preferred embodiment of this utility model, one end of the oil storage tank 7 is provided with two observation ports 701 that are respectively connected to the waste oil chamber 702 and the clean oil chamber 703. The two observation ports 701 are provided with transparent glass, and the transparent glass is provided with scale lines.
[0037] More specifically, by setting up an observation port 701, transparent glass, and scale lines, the remaining oil volume inside the waste oil chamber 702 and the clean oil chamber 703 can be observed in real time.
[0038] As a preferred embodiment of this utility model, liquid level sensors 14 are fixedly connected to the lower ends of the inner walls of both the waste oil chamber 702 and the clean oil chamber 703.
[0039] More specifically, by setting up a liquid level sensor 14, a warning can be issued when the oil level reaches a certain value (a simple audible and visual alarm can be set on bracket 1) to remind staff to replenish the oil level in time;
[0040] It should be noted that the liquid level sensor 14 is a mature existing technology, and its principle and internal structure will not be described in detail here. In addition, the liquid level sensor 14 can monitor and provide feedback on the oil level in the waste oil chamber 702 and the clean oil chamber 703 in real time. This allows the lubricating oil to be replenished first from the waste oil chamber 702 when it is being extracted. When the waste oil level drops to a certain level, the liquid level sensor 14 in the waste oil chamber 702 will issue an alarm. At this time, the solenoid valve 13 will be changed to extract clean oil from the clean oil chamber 703.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
