Description

Technical Field

[0001] This application relates to the field of municipal paving equipment technology, and in particular to a municipal road asphalt paving device. Background Technology

[0002] As is well known, in municipal road asphalt paving operations, the problem of asphalt residue in storage tanks directly affects construction efficiency and material utilization. Asphalt has the characteristics of high temperature viscosity and low temperature curing. After each paving operation, asphalt is easily left on the inner wall of the storage tank, the outlet and other parts, especially forming hardened lumps in corners and gaps. This not only wastes materials, but also reduces the effective volume of the storage tank, affecting the accuracy of subsequent operations.

[0003] Currently, a search reveals that a utility model patent with publication number CN209854237U discloses an asphalt concrete mixing equipment, whose storage tank adopts an inclined bottom design to reduce residue. However, the applicant has found that the existing technology is difficult to optimize the ease of cleaning the inner wall of the tank. The inclined angle is limited and there is a lack of corresponding active cleaning mechanisms. Asphalt adhering to the tank wall still needs to be manually scraped or melted at high temperature for cleaning, which is time-consuming, laborious and poses safety hazards.

[0004] Therefore, in response to the aforementioned technologies, we propose a municipal road asphalt paving device. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] The present application will be further described in detail below with reference to the accompanying drawings.

[0017] Please see Figures 1-4 In this embodiment of the utility model, a municipal road asphalt paving device includes: Main warehouse body 1; The cover 2 is adapted to the main body 1, and a limit component is provided between the cover 2 and the main body 1; The drive motor 3 is detachably connected to the compartment cover 2 via two mounting brackets 4, and the output shaft of the drive motor 3 is fixedly connected to the connecting shaft 5. Connecting ring 6 is disposed inside the cover 2, and connecting shaft 5 is rotatably disposed inside connecting ring 6; The connecting plate 7 is fixedly connected to the bottom of the connecting shaft 5, and two stirring rods 8 are fixedly connected to the bottom of the connecting plate 7. Multiple stirring blades 9 are fixedly connected to the outside of the stirring rods 8. Feed pipe 10 is installed on the bin cover 2 and is connected to the inner cavity of the main bin body 1. The unloading pipe 11 is located at one end of the main chamber 1 and is connected to the inner cavity of the main chamber 1. A regulating valve 12 is installed on the unloading pipe 11. The mounting component is located on the outer wall of the main compartment 1 and is used to fix the main compartment 1 in the usage position.

[0018] This municipal road asphalt paving device, during use, fixes the main chamber 1 to the paving machinery platform by installing components. Then, opens the pipe cover 18 of the feed pipe 10 and injects asphalt into the main chamber 1 through the feed pipe 10. Tightens the pipe cover 18 to prevent dust from entering. Starts the drive motor 3, whose output shaft drives the connecting plate 7 to rotate through the connecting shaft 5, causing the mixing rod 8 and spiral mixing blades 9 to mix the asphalt. During paving operations, the chamber cover 2 is closed, and a seal is achieved through the cooperation of the latch lock 13 and the clamping buckle 14. Opens the regulating valve 12 of the discharge pipe 11, and the asphalt is transported to the paving screed through the connecting pipe 19 under the push of gravity and the mixing blades 9. At this time, the mixing components prevent asphalt sedimentation during the discharge process. After paving is completed, the drive motor 3 and regulating valve 12 are turned off, the latch lock 13 is removed and the chamber cover 2 is taken off, and the inner wall of the main chamber 1 is flushed with high-pressure steam. The mixing blades 9 can be disassembled and cleaned with the connecting shaft 5, shortening the single cleaning time and ultimately achieving efficient asphalt paving and convenient equipment maintenance.

[0019] exist Figure 1-3 The limiting components include a latch lock 13 and a clamping buckle 14. The latch lock 13 and the clamping buckle 14 are symmetrically arranged at one end of the main body 1 and the cover 2, and the latch lock 13 and the clamping buckle 14 are compatible with each other.

[0020] This municipal road asphalt paving device, through this structure, can quickly achieve a sealed connection between the hopper cover 2 and the main hopper body 1. When the latch lock 13 is engaged and the buckle 14 is tightened, the sealing strip is compressed to 2mm, which effectively prevents asphalt vapor leakage. At the same time, it facilitates the quick disassembly of the hopper cover, with a single disassembly time of ≤10 seconds.

[0021] exist Figure 1-4 The installation component includes three installation blocks 15, which are symmetrically arranged on the outer wall of the main body 1. Each installation block 15 has an installation ring 16, and an installation bolt 17 is threaded into the installation ring 16.

[0022] This municipal road asphalt paving device, through its structure, has three mounting blocks arranged in a triangle, which are fixed to the paving machinery platform by mounting bolts 17, ensuring that the horizontal deviation of the main body is ≤0.5° and maintaining stability during vibration operation. The self-locking structure of the mounting rings 16 can prevent the bolts from loosening due to long-term vibration.

[0023] exist Figure 1-4In the main body 1, the feed pipe 10 is threaded with a pipe cap 18, one end of the discharge pipe 11 is connected to a connecting pipe 19, and a strip handle 20 is fixedly connected to the bin cover 2. The outer side of the strip handle 20 is fitted with an anti-slip rubber sleeve 21, and the bottom of the main bin body 1 is provided with an anti-slip rubber pad 22. With this structure, the pipe cap 18 of the feed pipe 10 can prevent dust from entering when not feeding. The discharge pipe 11 is connected to the paving equipment through the connecting pipe 19. The regulating valve 12 can adjust the flow rate from 0-90°. The strip handle 20 and the anti-slip rubber sleeve 21 make it easy for a single person to carry the bin cover. The anti-slip rubber pad 22 at the bottom of the main bin body has a friction coefficient ≥0.8, which prevents the equipment from slipping.

[0024] In this embodiment, the drive motor 3 is a commercially available device known to those skilled in the art. It can be customized or selected according to actual needs. Here, we are only using it without making any structural or functional improvements. We will not go into details here. The drive motor 3 is equipped with a matching control switch. The installation position of the control switch is selected according to actual usage needs to facilitate operation and control by the operator. The technology is already very mature and can be implemented.

[0025] The implementation principle of a municipal road asphalt paving device according to an embodiment of this application is as follows: First, the main chamber 1 is fixed to the paving machinery platform by the cooperation of three mounting blocks 15 and mounting bolts 17. The bottom anti-slip rubber pad 22 ensures the stability of the equipment. Then, the pipe cover 18 is opened, and asphalt (temperature 160-180℃) is injected into the main chamber 1 through the feed pipe 10. After closing the pipe cover, the drive motor 3 is started, and the stirring blade 9 starts to rotate and stir for 10 minutes to make the asphalt temperature uniform. Then, the chamber cover 2 is closed and locked with the latch lock 13. The main chamber is sealed with the clamping buckle 14. During the paving operation, the regulating valve 12 of the unloading pipe 11 is opened to a 60° opening. Asphalt is transported to the paving screed through the connecting pipe 19. At the same time, the mixing component runs at a low speed of 8 rpm to prevent asphalt sedimentation during unloading. After paving is completed, the regulating valve 12 is closed, the buckle lock 13 is removed and the chamber cover 2 is taken off. The inner wall of the main chamber is rinsed with high-pressure steam (150°C). The mixing blade 9 can be disassembled and cleaned with the connecting shaft 5. The cleaning time is shortened to 15 minutes and the risk of pipe blockage is reduced by 70%.

[0026] 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.
