Description

Technical Field

[0001] This utility model relates to the field of highway paving technology, specifically to an asphalt mixture paving device. Background Technology

[0002] Asphalt paving, a core component of road construction, encompasses numerous steps including material preparation, paving operations, compaction and shaping, and post-construction maintenance. Its construction quality has a direct and crucial impact on road smoothness, durability, and driving safety. Therefore, during road construction, specialized asphalt paving equipment is typically used, following standardized procedures and processes to ensure precise and efficient asphalt paving operations and guarantee the quality of road construction.

[0003] For example, Chinese invention patent CN114775375B discloses a road asphalt mixture paving device, including a mixing bin. A mounting plate is fixedly installed at the bottom of the mixing bin. A scraper is located behind the mounting plate at the bottom of the mixing bin, and a connecting frame is located behind the scraper at the bottom of the mixing bin. An opening is formed on the outer surface of the bottom of the mixing bin. This road asphalt mixture paving device, by setting up a mixing bin, baffles, sliding knobs, and side plates, allows for the activation of a cylinder inside the top frame during paving. This pushes the side plates downwards, aligning the asphalt on both sides to prevent asphalt from spilling and improving the paving effect. When the spacing between the side plates needs adjustment, a motor on the mounting plate is activated, driving a screw to rotate. The screw is threadedly connected to the top frame, causing the top frame to move along the screw, thus adjusting the position of the side plates. This device is quite practical.

[0004] The aforementioned asphalt pavement paving equipment for highways still has certain defects:

[0005] Although the aforementioned asphalt paving device can adjust the spacing between its two sides to even out the sides of the paved asphalt, in actual operation, the asphalt flowing from the mixing tank tends to accumulate in the middle, before it has been leveled by the scraper. In this situation, the accumulated asphalt easily comes into contact with and adheres to the screw, causing problems such as jamming and difficulty in rotation, ultimately interfering with the normal adjustment function of the paving device's side spacing. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an asphalt mixture paving device that makes the side plates easier to move and less prone to jamming.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an asphalt mixture paving device, comprising a mixing tank body and a baffle, wherein motors are fixedly connected to both sides inside the mixing tank body, a screw is fixedly connected to the output end of the motor, a connecting plate is threadedly connected to the screw, a connecting rod is fixedly connected to the end of the connecting plate away from the baffle, a side plate is fixedly connected to the end of the connecting rod away from the connecting plate, and a guide plate is slidably connected to the side of the side plate away from the connecting rod.

[0008] Furthermore, a fixing groove is provided in the middle of the side plate, and a lead screw is slidably connected inside the fixing groove. The end of the lead screw near the guide plate is fixedly connected to the guide plate, and the end of the lead screw away from the guide plate is threaded with a nut.

[0009] Furthermore, positioning grooves are provided at both ends of the side plate, and positioning blocks are slidably connected inside the positioning grooves. The end of the positioning block near the guide plate is fixedly connected to the guide plate.

[0010] Furthermore, the end of the connecting plate away from the connecting rod is fixedly connected to the baffle.

[0011] Furthermore, both ends of the top of the side plate are provided with sliding grooves, and a slider is slidably connected inside the sliding groove, and the slider is fixedly connected to the main body of the mixing box.

[0012] Furthermore, the end of the slider near the baffle is inclined.

[0013] Furthermore, an anti-detachment block is fixedly attached to the end of the screw away from the motor.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] When the side plate of this asphalt mixture paving device needs to be moved, simply start the motor. The motor then drives the screw to rotate, and the connecting plate, which is threaded to the screw, will slide along the bottom of the mixing box body with the side plate, thereby changing the position of the side plate. Since the screw is located on the outside of the mixing box body, the screw is less likely to stick to the asphalt mixture, making the movement of the side plate simpler and more convenient.

[0020] 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.

[0021] Please see Figure 1-3 An asphalt mixture paving device includes a mixing tank body 1 and a baffle 2. Motors 3 are fixedly connected to both sides inside the mixing tank body 1. A screw 4 is fixedly connected to the output end of the motor 3. A connecting plate 6 is threadedly connected to the screw 4. A connecting rod 7 is fixedly connected to the end of the connecting plate 6 away from the baffle 2. A side plate 8 is fixedly connected to the end of the connecting rod 7 away from the connecting plate 6. A guide plate 11 is slidably connected to the side of the side plate 8 away from the connecting rod 7.

[0022] In this utility model, when the side plate 8 needs to be moved, only the motor 3 needs to be started. Then, the motor 3 drives the screw 4 to rotate, and the connecting plate 6, which is threaded to the screw 4, will slide along the bottom of the mixing box body 1 with the side plate 8, thereby changing the position of the side plate 8. Since the screw 4 is located on the outside of the mixing box body 1, the screw 4 is not easy to stick to the asphalt mixture, and the movement of the side plate 8 is simpler and more convenient. In addition, the structure of the mixing box body 1 in this utility model is similar to the prior art, which discloses a highway pavement asphalt mixture paving device structure in the patent authorized publication number CN114775375B, so it will not be described in detail here.

[0023] like Figure 3 As shown, a fixing groove 10 is provided in the middle of the side plate 8. A lead screw 13 is slidably connected inside the fixing groove 10. The end of the lead screw 13 near the guide plate 11 is fixedly connected to the guide plate 11, and the end of the lead screw 13 away from the guide plate 11 is threadedly connected to a nut 14.

[0024] Specifically, when it is necessary to adjust the height of the guide plate 11 according to the thickness of the asphalt mixture, simply loosen the nut 14 first, then slide the guide plate 11 until it slides to the appropriate position, and then tighten the nut 14 again.

[0025] like Figure 3 As shown, both ends of the side plate 8 are provided with positioning grooves 9, and positioning blocks 12 are slidably connected inside the positioning grooves 9. The end of the positioning block 12 near the guide plate 11 is fixedly connected to the guide plate 11.

[0026] Specifically, during the movement of the guide plate 11, the positioning block 12 will slide in the positioning groove 9, thereby restricting the guide plate 11 and making the guide plate 11 more convenient to slide.

[0027] like Figure 1 and Figure 3 As shown, the end of the connecting plate 6 away from the connecting rod 7 is fixedly connected to the baffle 2. The connection between the connecting plate 6 and the baffle 2 allows the baffle 2 to move together with the connecting plate 6, thus making the movement of the baffle 2 more convenient.

[0028] like Figure 1 and Figure 3 As shown, both ends of the top of the side plate 8 are provided with sliding grooves 15, and a slider 16 is slidably connected inside the sliding groove 15. The slider 16 is fixedly connected to the mixing box body 1.

[0029] Specifically, during the movement of the side plate 8, the slider 16 and the groove 15 will restrict the slider 16, making it easier for the side plate 8 to move.

[0030] like Figure 1 As shown, the end of the slider 16 near the baffle 2 is inclined. The inclined slider 16 makes it difficult for the asphalt mixture to enter the groove of the slider 16, thus preventing the side plate 8 from being blocked by the asphalt mixture.

[0031] like Figure 1 and Figure 2 As shown, an anti-detachment block 5 is fixed to the end of the screw 4 away from the motor 3. The anti-detachment block 5 restricts the connecting plate 6, making it difficult for the connecting plate 6 to detach from the screw 4.

[0032] 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.
