Description

Technical Field

[0001] This utility model relates to the field of asphalt concrete technology, specifically to a recycled asphalt concrete collection device. Background Technology

[0002] Asphalt roads are widely used in my country, especially highways, which are mostly paved with asphalt concrete. Highways have now entered the maintenance stage. In order to reduce maintenance costs and improve the utilization rate of recycled resources, asphalt concrete recycling technology is often used. Asphalt concrete recycling technology requires the collection of waste materials generated from milling old road surfaces.

[0003] Among them, announcement number CN210420835U discloses a recycled asphalt concrete collection device, which uses an exhaust fan installed on the side plate to collect the dust generated during the collection of old materials into a dust storage bin, thus avoiding pollution to the surrounding environment during construction.

[0004] However, in actual use, due to the large amount of dust inside the milled asphalt waste, the waste will vibrate and some waste will roll and fall during the process of entering the collection shovel. The vibration and falling of the waste will generate a large amount of dust, and the exhaust fan on the side plate surface cannot effectively suck up the external dust, which will cause this dust to drift into the environment and pollute the surrounding environment.

[0005] Therefore, it is necessary to invent a recycled asphalt concrete collection device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a recycled asphalt concrete collection device to solve the problem that the exhaust fan on the side plate surface cannot effectively suck up external dust, which causes the dust to drift into the environment and pollute the surrounding environment.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a recycled asphalt concrete collection device, comprising a collection hopper, the collection hopper comprising a collection shovel, a support frame, a conveyor net, and an equipment shell, the support frame being fixedly connected to the rear end of the collection shovel, the lower end of the equipment shell being fixedly connected to the upper end of the collection shovel and the support frame, the conveyor net being disposed inside the support frame, and a dust suppression component being disposed at the upper end of the equipment shell, the dust suppression component comprising a water storage tank, a suction pump, a first diversion pipe, a connecting pipe, a second diversion pipe, a first nozzle, a mounting frame, a mounting groove, a second nozzle, a fixing screw, and a locking nut.

[0008] By adopting the above technical solution, the collection hopper is used to collect waste materials. During the collection process, the water inside the water storage tank is pumped by the suction pump to the inside of the first and second nozzles, and water mist is sprayed into the inside and around the outside of the collection hopper. This effectively reduces the dust generated during the waste collection process, effectively prevents dust from spreading, and improves the cleanliness of the surrounding environment.

[0021] Optionally, the surface of the material shovel is provided with multiple sets of positioning grooves, and each set of positioning grooves is rotatably connected to a transmission roller.

[0022] By adopting the above technical solution, the transmission roller reduces the friction between waste and the collection shovel, thereby increasing the waste collection speed.

[0026] 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.

[0027] This utility model provides, for example Figures 1 to 4 The illustrated recycled asphalt concrete collection device includes a collection hopper 1, which comprises a collection shovel 11, a support frame 12, a conveyor net 17, and a housing 2. The surface of the collection shovel 11 has multiple sets of positioning grooves 15, each containing a drive roller 16 rotatably connected to it. The support frame 12 is fixedly connected to the rear end of the collection shovel 11, and two sets of drive rollers 13 are rotatably connected inside the support frame 12. Both ends of the conveyor net 17 are connected to the two sets of drive rollers 13. A first sprocket 14 is fixedly connected to the right end of the rear drive roller 13. The lower end of the shell 2 is fixedly connected to the upper end of the material shovel 11 and the support frame 12. The conveyor net 17 is set inside the support frame 12. A first protective cover 21 is fixedly connected to the right side surface of the equipment shell 2. A transmission chain 22 is set inside the first protective cover 21. A second protective cover 23 is fixedly connected to the right side of the upper end of the equipment shell 2. A drive motor 24 is fixedly installed inside the equipment shell 2. A second sprocket 25 is fixedly connected to the output end of the drive motor 24. The upper and lower ends of the transmission chain 22 are respectively connected to the first sprocket 14 and the second sprocket 25.

[0028] During the waste collection process, the collection hopper 1 is pushed forward, and the collection shovel 11 scoops up the waste from the bottom, allowing the waste to slide into the collection hopper 1 through multiple sets of transmission rollers 16 on its surface. When the waste comes into contact with the conveyor net 17, the conveyor net 17 quickly moves the waste to the rear, which facilitates the rapid collection of waste and improves the waste collection speed.

[0029] Specifically, the output of the drive motor 24 drives the second sprocket 25 to rotate. The second sprocket 25, in conjunction with the transmission chain 22, drives the first sprocket 14 to rotate, which in turn drives the rear transmission roller 13 to rotate. The two sets of transmission rollers 13 work together to drive the conveyor net 17 to rotate, quickly moving the waste material to the rear of the collection hopper 1. The surface of the conveyor net 17 is provided with multiple sets of anti-slip protrusions to increase the friction with the waste material.

[0030] See Figure 1 , Figure 4 and Figure 5 The upper end of the equipment housing 2 is equipped with a dust suppression component, which includes a water storage tank 3, a suction pump 31, a first diversion pipe 32, a connecting pipe 33, a second diversion pipe 34, a first nozzle 35, a mounting bracket 4, a mounting groove 41, a second nozzle 42, a fixing screw 43, and a locking nut 44. The water storage tank 3 is fixedly connected to the left side of the upper end of the equipment housing 2. The suction pump 31 is fixedly installed at the front end of the water storage tank 3. The outlet end of the suction pump 31 is fixedly connected to the first diversion pipe 32. The end of the first diversion pipe 32 away from the suction pump 31 is fixedly connected to three sets of second nozzles 42. The connecting pipe 33 is fixedly connected to the lower side of the first diversion pipe 32. The second diversion pipe 34 is fixedly connected to the lower end of the connecting pipe 33. The surface of the second diversion pipe 34 is fixedly connected to four sets of first nozzles 35.

[0031] In addition, during the waste collection process, the suction pump 31 is activated. The suction pump 31 delivers water through the first diversion pipe 32 to the interior of the three sets of second nozzles 42. The second nozzles 42 atomize the water and spray it onto the outside of the collection hopper 1 to suppress dust on the outside of the collection hopper 1. At the same time, the suction pump 31 delivers water through the connecting pipe 33 and the second diversion pipe 34 to the interior of the four sets of first nozzles 35. The first nozzles 35 atomize the water and spray it into the interior of the collection hopper 1 to suppress dust on the inside of the collection hopper 1, effectively preventing the spread of dust during the waste collection process and improving environmental cleanliness.

[0032] See Figure 5 and Figure 6 Three sets of mounting brackets 4 are provided on the upper side of the equipment housing 2. Each of the three sets of mounting brackets 4 has a mounting groove 41 at its upper end. The left and right sides of the second nozzle 42 are fixedly connected to the fixing screws 43. The fixing screws 43 are locked inside the mounting grooves 41. The locking nut 44 is threadedly connected to the end of the fixing screw 43. The left and right sides of the upper end of the equipment housing 2 are fixedly connected to the linear guide rails 5. The upper side of the linear guide rails 5 is slidably connected to the mounting base 51. The lower ends of the left and right sets of mounting brackets 4 are fixedly connected to the surface of the mounting base 51. The lower end of the middle mounting bracket 4 is fixedly connected to the surface of the equipment housing 2. The upper surface of the mounting base 51 near the rear side is threadedly connected to the locking screw 52. The lower end of the locking screw 52 abuts against the surface of the linear guide rail 5.

[0033] Meanwhile, during the waste collection process, when the dust is large, the mounting base 51 can be slid forward on the surface of the linear guide rail 5, thereby moving the second nozzles 42 on the left and right sides forward, increasing the spraying range of the second nozzles 42. Furthermore, the spraying angle can be adjusted by rotating the second nozzles 42, further improving the dust suppression effect.

[0034] The working principle of this utility model is as follows: The water inside the water storage tank 3 is pumped by the suction pump 31 to the inside of the first nozzle 35 and the second nozzle 42, spraying water mist into the inside and around the outside of the collection hopper 1, effectively reducing dust generated during the collection of waste materials, effectively preventing dust diffusion, and improving the cleanliness of the surrounding environment; At the same time, the mounting base 51 slides back and forth on the surface of the linear guide rail 5, thereby adjusting the front and back positions of the second nozzles 42 on the left and right sides, thereby effectively increasing the spraying range of the second nozzles 42, increasing the coverage of the water mist, and further improving the dust reduction effect.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
