Description

Technical Field

[0001] This application relates to the field of asphalt mixing technology, specifically to an automatic asphalt mixing machine. Background Technology

[0002] Asphalt is mainly used in industries such as coatings, plastics, and rubber, as well as in road paving. Asphalt mixing plants are essential mixing machines for preparing asphalt, sand and gravel mixtures or cement, sand and gravel mixture samples.

[0003] An existing patent (publication number: CN 220952796 U) discloses an asphalt mixture mixing machine, belonging to the field of asphalt mixing technology. It includes a mixing mechanism, a lid mechanism, and a heating component. The mixing mechanism comprises a mixing drum, a feeding auger, a first receiving trough, a second receiving trough, and support legs. The bottom of the mixing drum is connected to the feeding auger. The first receiving trough is formed on the top of the mixing drum wall, and the second receiving trough is formed on the wall of the feeding auger. Support legs are provided at the bottom of the mixing drum. The lid mechanism is located on the top of the mixing drum and includes a cover plate, a stirrer, and a hopper. The stirrer is located at the center of the cover plate. The feeding auger conveys the mixed asphalt mixture. Heating components are provided on the mixing drum and the feeding auger to heat the asphalt mixture, maintaining its flowability and facilitating mixing and flow of the asphalt mixture.

[0004] Although the device in the aforementioned comparative document solves the problem of not being able to continue heating asphalt, the device has a simple structure, poor mixing effect when mixing materials, cannot clean the asphalt residue on the inner wall of the device, and is not convenient for people to filter and discharge the exhaust gas generated during the mixing process. In order to solve the above problems, an automatic asphalt mixing machine is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an automatic asphalt mixing machine with advantages such as a multi-functional mixing structure and gas filtration and emission functions. This solves the problems of poor mixing effect, inability to clean residual asphalt on the inner wall of the device, and inconvenience for filtering and emitting exhaust gas generated during the mixing process.

[0006] To achieve the above objectives, this application provides the following technical solution: an automatic asphalt mixing machine, comprising a barrel body, wherein a top cover is installed on the top of the barrel body by a plurality of mounting bolts, and an agitator motor, a feed pipe and an exhaust pipe are fixedly connected to the top of the top cover;

[0007] The output end of the agitator motor rotates through the top of the top cover and is fixedly connected to a rotating rod. Multiple agitator rods are fixedly connected to the surface of the rotating rod. An agitator auger is fixedly connected to the bottom end of the rotating rod. An L-shaped scraper is fixedly connected to the surface of the rotating rod. The side of the L-shaped scraper overlaps the inner wall of the barrel. A feed box is fixedly connected to the top of the feed pipe. A rotating baffle is movably connected to the inner side of the feed box via a pin. A connecting spring is fixedly connected to the bottom of the rotating baffle. The bottom end of the connecting spring is fixedly connected to the inner side of the feed box. An exhaust fan and a filter box are fixedly connected inside the exhaust pipe. An mounting plate is bolted to the front of the filter box. A filter plate is fixedly connected to the surface of the mounting plate. The filter plate is located inside the filter box.

[0008] The above scheme, by setting up an agitator motor, causes the rotating rod, agitator rod, agitator auger, and L-shaped scraper to rotate. The rotation of the agitator rod breaks up material clumps, promoting uniform mixing of asphalt and aggregate. The rotation of the agitator auger pushes the material at the bottom upwards, forming a circulating mixing flow and preventing sedimentation. The rotation of the L-shaped scraper removes asphalt adhering to the barrel wall, preventing clumping and improving mixing efficiency. By setting up a rotating baffle and connecting spring, the inlet of the device can be blocked during material mixing, preventing dust from entering the barrel. By setting up an exhaust pipe and exhaust fan, exhaust gas can be forcibly drawn in. By setting up a filter plate, multiple layers of filters can adsorb harmful substances and purify the exhaust gas.

[0009] Furthermore, a sliding frame is fixedly connected to the inner side of the filter box, and the filter plate is slidably connected within the sliding frame.

[0010] The above solution, by setting a sliding frame, can guide the filter plate to slide along the track, which can simplify the disassembly and assembly process.

[0011] Furthermore, a concave sealing strip is provided at the bottom of the top cover, and a convex sealing strip is provided at the top of the barrel body, with the convex sealing strip snapping into the concave sealing strip.

[0012] The above solution, through the interlocking of the convex and concave sealing strips, can form a double seal to prevent liquid leakage.

[0013] Furthermore, a conical hopper is fixedly connected to the bottom of the barrel, an L-shaped discharge pipe is fixedly connected to the bottom of the conical hopper, and a conical discharge pipe is fixedly connected to the output end of the L-shaped discharge pipe.

[0014] The above scheme uses a conical hopper to guide the mixture towards the outlet, avoiding residue; an L-shaped discharge pipe to extend the material discharge path, facilitating control of the discharge speed; and a conical discharge pipe to concentrate the discharge and prevent splashing.

[0015] Furthermore, a control valve is installed inside the L-shaped discharge pipe.

[0016] The above solution allows for precise control of the discharge volume by adjusting the opening and closing degree of the L-shaped discharge pipe through the setting of a control valve.

[0017] Furthermore, a discharge motor is fixedly connected to the surface of the L-shaped discharge pipe, and the output end of the discharge motor rotates through the L-shaped discharge pipe and is fixedly connected to an output auger.

[0018] The above scheme, by setting up a discharge motor, can drive the output auger to rotate, thus providing forced discharge power for high-viscosity asphalt mixture.

[0019] Furthermore, both the interior of the L-shaped discharge pipe and the interior of the barrel are equipped with heating layers.

[0020] The above solution, by setting up a heating layer, can maintain the temperature of the asphalt in the barrel and the discharge pipe, preventing it from cooling and solidifying.

[0021] Furthermore, a plurality of support rods are fixedly connected to the bottom of the conical bucket, and a support pad is fixedly connected to the bottom end of the support rods.

[0022] The above solution, by setting up support rods and support pads, can distribute the weight of the equipment, provide stability, and reduce equipment vibration.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This automatic asphalt mixing machine features an agitator motor that rotates a rotating rod, an agitator, an agitator auger, and an L-shaped scraper. The rotation of the agitator breaks up material clumps, promoting uniform mixing of asphalt and aggregates. The rotation of the agitator auger pushes material upwards from the bottom, creating a circulating mixing flow and preventing sedimentation. The rotation of the L-shaped scraper removes asphalt adhering to the drum wall, preventing clumping and improving mixing efficiency. A rotating baffle and connecting spring can seal the feed inlet during mixing, preventing dust from entering the drum. An exhaust pipe and exhaust fan forcefully extract waste gas, and multiple filter plates adsorb harmful substances, purifying the emitted gases. Attached Figure Description

A feed box 208 is fixedly connected to the top of the feed pipe 207. A rotating baffle 209 is movably connected to the inner side of the feed box 208 via a pin. A connecting spring 2010 is fixedly connected to the bottom of plate 209. The bottom end of the connecting spring 2010 is fixedly connected to the inner side of the feed box 208. An exhaust fan 2012 and a filter box 2013 are fixedly connected inside the exhaust pipe 2011. A mounting plate 4 is bolted to the front of the filter box 2013. A filter plate 401 is fixedly connected to the surface of the mounting plate 4. The filter plate 401 is located inside the filter box 2013. By setting an agitator motor 202, when the agitator motor 202 is running, it can rotate the rod 203. The stirring rod 204, the agitator 205, and the L-shaped scraper 206 rotate. The rotation of the stirring rod 204 breaks up material clumps, promoting uniform mixing of asphalt and aggregate. The rotation of the agitator 205 pushes the material at the bottom upwards, forming a circulating mixing flow and preventing sedimentation. The rotation of the L-shaped scraper 206 scrapes away asphalt adhering to the barrel wall, preventing clumping and improving mixing efficiency. A rotating baffle 209 and a connecting spring 2010 are installed to enhance the mixing effect during material mixing. The feed inlet of the device can be blocked to prevent dust from flowing into the barrel 1. By setting the exhaust pipe 2011 and exhaust fan 2012, exhaust gas can be forcibly sucked in. By setting the filter plate 401, multiple layers of filter screens can adsorb harmful substances and purify the exhaust gas. The inside side of the filter box 2013 is fixedly connected to the sliding frame 2014, and the filter plate 401 is slidably connected in the sliding frame 2014. By setting the sliding frame 2014, the filter plate 401 can be guided to slide along the track, which can simplify the disassembly and assembly process.

An L-shaped discharge pipe 103 is fixedly connected to the bottom of the conical hopper 101. A conical discharge pipe 105 is fixedly connected to the output end of the L-shaped discharge pipe 103. By setting the conical hopper 101, the mixture can be guided to the outlet to concentrate and avoid residue. By setting the L-shaped discharge pipe 103, the material discharge path can be extended, making it easier to control the discharge speed. By setting the conical discharge pipe 105, the discharge can be concentrated and splashing can be prevented. A control valve 104 is set inside the L-shaped discharge pipe 103.

A discharge motor 108 is fixedly connected to the surface of the L-shaped discharge pipe 103. The output end rotates through the L-shaped discharge pipe 103 and is fixedly connected to the output auger 109. By setting the discharge motor 108, the operation of the discharge motor 108 can drive the output auger 109 to rotate, which can provide forced discharge power for high viscosity asphalt mixture. The L-shaped discharge pipe 103 and the barrel 1 are both provided with heating layers 1010. By setting the heating layers 1010, the temperature of the asphalt in the barrel 1 and the discharge pipe can be maintained to prevent cooling and solidification. Multiple support rods 102 are fixedly connected to the bottom of the conical bucket 101. Support pads 1107 are fixedly connected to the bottom of the support rods 102.

[0040] In this embodiment, by setting up an agitator motor 202, the operation of the agitator motor 202 can rotate the rotating rod 203, agitator rod 204, agitator auger 205, and L-shaped scraper 206. The rotation of the agitator rod 204 can break up material clumps and promote uniform mixing of asphalt and aggregate. The rotation of the agitator auger 205 can push the material at the bottom upward to form a circulating mixing flow and avoid sedimentation. The rotation of the L-shaped scraper 206 can scrape off the asphalt adhering to the barrel wall to prevent clumping and improve mixing efficiency. By setting up a rotating baffle 209 and a connecting spring 2010, the inlet of the device can be blocked when the material is being mixed, which can prevent dust from flowing into the barrel 1. By setting up an exhaust pipe 2011 and an exhaust fan 2012, exhaust gas can be forcibly sucked in. By setting up a filter plate 401, multiple layers of filter screens can adsorb harmful substances and purify the exhaust gas.

[0041] The working principle of the above embodiment is as follows: During use, materials can be poured into the barrel 1 through the feed box 208 and feed pipe 207. After pouring, the stirring motor 202 runs, which can rotate the rotating rod 203, stirring rod 204, stirring auger 205 and L-shaped scraper 206. The rotation of the stirring rod 204 can break up material clumps and promote the uniform mixing of asphalt and aggregate. The rotation of the stirring auger 205 can push the bottom material upward to form a circulating stirring flow and avoid sedimentation. At the same time, the rotation of the L-shaped scraper 206 scrapes off the asphalt adhering to the barrel wall to prevent clumping. After the mixing is completed, the control valve 104 is opened, and the mixture can flow into the L-shaped discharge pipe 103. Then the discharge motor 108 runs, which can drive the output auger 109 to rotate, which can provide forced discharge power for the high viscosity asphalt mixture, so that the mixture can be discharged.
