Description

Technical Field

[0001] This utility model relates to the field of warm mix asphalt construction technology, specifically to a low-carbon emission, large-void drainage asphalt concrete pavement warm mix construction device. Background Technology

[0002] Asphalt concrete, also known as asphalt concrete, is a mixture made by artificially selecting mineral materials with a certain gradation, such as crushed stone or crushed gravel, stone chips or sand, mineral powder, etc., and mixing them with a certain proportion of road asphalt materials under strict control conditions.

[0003] A search revealed existing technology (publication number: CN217419218U), which describes "an asphalt concrete mixing device for road construction, relating to the field of road construction. This asphalt concrete mixing device includes a base, a working box, a mixing drum, and a servo motor. A mixing blade is fixedly welded to the lower end of the output shaft of the servo motor, and a scraper is fixedly connected to one end of the mixing blade that is far apart from the other. A motor is fixedly installed on the left side of the upper surface of the base, and a spiral blade is fixedly welded to the right end of the motor's output shaft. A discharge pipe is embedded in the bottom right side of the working box. This asphalt concrete mixing device for road construction, through the cooperation of the servo motor, mixing blades, and scraper, can more thoroughly mix the materials in the mixing drum, improving work efficiency. The scraper rotates along the inner wall of the mixing drum, thereby scraping off the asphalt adhering to the inner wall, saving manpower for manual cleaning and improving practicality."

[0004] While existing asphalt concrete mixing plants for road construction have achieved convenient cleaning and material discharge, they still have some shortcomings: the working box of existing asphalt concrete mixing plants can only mix horizontally, and there is uneven mixing in the vertical direction inside the working box, meaning that the internal materials cannot be turned upside down. Secondly, the mixture coming out of the discharge pipe is not convenient to be used directly for road paving and needs to be collected in other containers before paving, which is quite troublesome. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, a low-carbon emission, large-void drainage asphalt concrete pavement warm-mix construction device is provided to solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, a low-carbon emission, large-void drainage asphalt concrete pavement warm-mix construction device is provided, comprising: a movable seat and a base. Rollers are installed on the lower side of the movable seat, and a connector is attached to the outer end of the movable seat. A hydraulic rod and a hinge seat are installed on the upper side of the movable seat. The base is installed on the upper end of the hydraulic rod and the hinge seat, and a side plate is installed on the upper side of the base. A mixing cylinder is installed and connected between the side plates. A conveying screw is provided inside the mixing cylinder, and a driven gear and a driving gear are connected to the outer side of the mixing cylinder. An inlet and outlet are connected to the outer wall of the mixing cylinder. A material distribution plate is provided on the upper side of the base, and a guide plate is provided on the lower side of the material distribution plate. A discharge hole is opened on the lower side of the guide plate inside the movable seat.

[0007] Furthermore, the connector is designed with a Z-shaped structure, and the connector is attached to the end of the movable base.

[0008] Furthermore, the lower side of the base is hinged to the upper end of the hydraulic rod, and the base is also hinged to the hinge seat, and the interior of the base is provided with a through hole.

[0009] Furthermore, the guide plate has a guide groove inside, and the guide plate is connected to the lower side of the through hole and fixed to the lower side of the base.

[0010] Furthermore, the inner side of the material distribution plate is provided with a material guide groove, and the inner side of the material distribution plate is provided with a baffle plate, and one end of the baffle plate is connected to an angle motor.

[0011] Furthermore, the mixing cylinder is rotatably connected between the side plates, and the two ends of the mixing cylinder are connected to rotating shafts. The driven gear is connected to the rotating shaft, and the driving gear meshes with the driven gear for transmission. A first motor is connected to one side of the driving gear.

[0012] Furthermore, one end of the feeding screw rotates through the side plate and connects to the second motor, and the second motor is mounted on the outer wall of the side plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. When using, pour the asphalt concrete raw materials into the mixing drum through the inlet and outlet, then seal the inlet and outlet, and then start the first motor and the second motor. At this time, the first motor drives the mixing drum to rotate through the meshing of the drive gear and the driven gear, while the second motor drives the conveying screw to rotate, thereby achieving mixing and stirring of the raw materials inside the mixing drum. At the same time, the rotation of the mixing drum can drive the internal raw materials to tumble, further enhancing the uniformity of the mixture.

[0015] 2. The hydraulic rod and hinge seat facilitate the reversal of one side of the base. At this time, the inlet and outlet are located on the upper side of the material distribution plate. Then, the valves of the inlet and outlet are opened, and the second motor is started again to control the reversal of the second motor. At this time, the material is fed to the inlet and outlet side through the feeding screw. The mixture passes through the baffle plate inside the material distribution plate, so that the mixture is spread down from the guide trough, and then falls onto the road surface to be paved through the through hole, guide plate and discharge hole, thus achieving the effect of easy direct paving and use.

[0021] Reference Figures 1 to 4 As shown, this utility model provides a low-carbon emission, large-void drainage asphalt concrete pavement warm-mix construction device, including: a movable seat 1 and a base 2. Rollers 11 are installed on the lower side of the movable seat 1, and a connector 12 is connected to the outer end of the movable seat 1. A hydraulic rod 13 and a hinge seat 14 are installed on the upper side of the movable seat 1. The base 2 is installed on the upper end of the hydraulic rod 13 and the hinge seat 14. A side plate 21 is installed on the upper side of the base 2, and a mixing cylinder 3 is installed and connected between the side plates 21. A conveying screw 35 is provided inside the mixing cylinder 3, and a driven gear 32 and a driving gear 33 are connected to the outer side of the mixing cylinder 3. An inlet and outlet port 31 is connected to the outer wall of the mixing cylinder 3. A material equalization plate 22 is provided on the upper side of the base 2, and a guide plate 23 is provided on the lower side of the material equalization plate 22. A discharge hole 15 is opened on the lower side of the guide plate 23 and inside the movable seat 1.

[0022] In this embodiment, the movable seat 1, the base 2, and the mixing cylinder 3 constitute the main structure of the low-carbon emission, large-void drainage asphalt concrete pavement warm-mix construction device involved in this application.

[0023] Specifically, the side plate 21 is configured as a set of parallel plate structures, and the driving gear 33 and the driven gear 32 are located inside the side plate 21.

[0024] Specifically, the mixing cylinder 3 is designed as a cylindrical structure, with the inlet and outlet 31 and the uniform material plate 22 located on one side, and there is no interference between the mixing cylinder 3 and the uniform material plate 22 during the rotation of the mixing cylinder 3.

[0025] like Figure 1 , Figure 3 and Figure 4 In the middle, the connecting member 12 is set as a Z-shaped structure, and the connecting member 12 is connected to the end of the movable seat 1. The lower side of the base 2 is hinged to the upper end of the hydraulic rod 13, and the base 2 is also hinged to the hinge seat 14. The interior of the base 2 is provided with a through hole 24. The interior of the guide plate 23 is provided with a guide groove 231, and the guide plate 23 is connected to the lower side of the through hole 24 and fixed to the lower side of the base 2. The inner side of the material equalization plate 22 is provided with a guide groove 221, and the inner side of the material equalization plate 22 is provided with a baffle plate 222. One end of the baffle plate 222 is connected to the angle motor 223.

[0026] Specifically, the material distribution plate 22 is open on the side facing the inlet / outlet 31, and the baffle plate 222 is an inclined rectangular plate structure. The baffle plate 222 has connecting shafts at both ends, and there is a discharge gap between the baffle plate 222 and the inner wall of the material distribution plate 22.

[0027] As a preferred implementation, by setting an angle motor 223, it is easier to control the angle of the baffle plate 222, thereby making it easier to control the size of the material discharge gap between the baffle plate 22 and the inner wall of the material distribution plate 22, and thus making it easier to control the material discharge speed.

[0028] like Figure 1 and Figure 2 In the middle, the mixing cylinder 3 is rotatably connected between the side plates 21, and the two ends of the mixing cylinder 3 are connected to the rotating shafts, and the driven gear 32 is connected to the rotating shafts. At the same time, the driving gear 33 meshes with the driven gear 32 for transmission, and a first motor 34 is connected to one side of the driving gear 33. One end of the conveying screw 35 rotates through the side plate 21 and is connected to the second motor 36, and the second motor 36 is installed on the outer wall of the side plate 21.

[0029] Specifically, one side of the mixing drum 3 is designed as a hollow shaft structure, and one end of the conveying screw 35 rotates through the hollow shaft and the side plate 21, so that the conveying screw 35 and the mixing drum 3 do not interfere with each other when they rotate, thereby achieving a more uniform mixing effect.

[0030] In use, asphalt concrete raw materials are poured into the mixing drum through the inlet and outlet, then the inlet and outlet are sealed. The first and second motors are then started. The first motor drives the mixing drum to rotate via the meshing of the drive and driven gears, while the second motor drives the conveying screw to rotate. This mixes the raw materials inside the mixing drum, and the drum's rotation also causes the internal materials to tumble, further enhancing the uniformity of the mixture. A hydraulic rod and hinged seat facilitate reversing one side of the base, placing the inlet and outlet above the material leveling plate. The valves at the inlet and outlet are then opened, and the second motor is started again, reversing it. The material is then conveyed to the inlet and outlet side via the conveying screw. The mixture passes through the baffle plate inside the material leveling plate, spreading downwards from the guide trough. It then passes through the through holes, guide plates, and discharge holes onto the road surface to be paved, thus achieving a convenient direct paving application.

[0031] The low-carbon emission, large-void drainage asphalt concrete pavement warm-mix construction device of this utility model can effectively solve the problems mentioned in the background technology. It achieves better uniform mixing effect and direct discharge paving effect on the basis of existing low-carbon emission, large-void drainage asphalt concrete pavement warm-mix construction device technology.
