Description

Technical Field

[0001] The present invention relates to the technical field of road construction equipment, and in particular to an environmentally friendly asphalt precise mixing and paving device. Background Art

[0002] In modern road construction projects, asphalt pavement paving is a key link, and its construction quality is directly related to the service life of the road, driving safety and comfort. However, traditional asphalt mixing paving devices have many thorny problems and are difficult to meet the current stringent requirements of high-quality, high-efficiency and environmentally friendly construction.

[0003] On the one hand, it is difficult for traditional equipment to accurately control the composition ratio and mixing uniformity of asphalt mixtures. For example, in the process of mixing aggregates, asphalt and additives, the simple mixing structure cannot ensure that the materials are fully integrated, resulting in segregation of the finished mixture. Local weak areas are easily formed on the paved road surface, which are quickly damaged under long-term vehicle rolling, greatly shortening the road maintenance cycle, increasing the subsequent maintenance costs and the risk of traffic congestion.

[0004] On the other hand, the bottleneck of construction efficiency is obvious. Most traditional devices lack the ability to move flexibly and turn quickly. In large-scale construction sites or complex construction sites, equipment transfer and positioning are time-consuming and labor-intensive, seriously slowing down the progress of the project; the paving process is also unsatisfactory. It is impossible to flexibly adjust the paving thickness, width and slope according to actual working conditions. When facing sections with different design requirements, frequent shutdowns are required for manual adjustments, which seriously affects the continuity of construction and overall efficiency.

[0005] Furthermore, environmental protection problems need to be solved urgently. The heating and mixing of asphalt will release a large amount of harmful gases such as benzene and phenols, as well as pungent smoke and dust. The sealing performance of traditional devices is poor, and harmful gases are released at the feed inlet, mixing barrel and other parts. The air quality at the construction site is poor, and construction workers are exposed to it for a long time, and respiratory diseases are frequent. The untreated pollutants are discharged at will, which also causes irreversible damage to the surrounding ecological environment, causing complaints from surrounding residents, and causing the project to face environmental penalties and the risk of suspension of work for rectification.

[0006] In addition, the cleaning and maintenance problems of traditional equipment cannot be ignored. Asphalt is highly viscous and easily adheres to the barrel wall during the mixing process. Over time, this not only reduces the mixing efficiency, but also affects the heat transfer performance of the equipment, increases energy consumption, and frequent manual cleaning is time-consuming and dangerous, further eroding the normal operation time and economic benefits of the equipment.

[0007] In order to effectively solve the above-mentioned problem, the present invention proposes an environmentally friendly asphalt precise mixing and paving device. Summary of the invention

[0043] A support frame 61 is fixedly installed at the bottom of the base 1, and a support seat 62 is rotatably installed on the support frame 61. Cylinders 6 are hingedly installed on both sides of the support seat 62. Motor three 602 is fixedly installed on the side of the two cylinders 6 close to each other.

[0044] In order to be able to control the deflection of the two cylinders 6 based on the support seat 62 as needed, so as to facilitate the rapid adjustment of the width of a single paving, and at the same time to adjust the inclination of the cylinder 6 as needed, so as to be able to well adapt to the effect of asphalt paving operations on roads with different slopes, a guide ring 71 is rotatably installed on the bottom side of the base 1 based on the support frame 61, and a toothed disc 7 is fixedly installed on the bottom side of the guide ring 71.

The two hydraulic cylinders 63 are hingedly installed on the bottom side of the toothed disc 7 and are symmetrically arranged based on the support frame 61.

[0045] In this embodiment, in order to reduce the emission of harmful gases during the asphalt mixing and stirring process and protect the health of construction workers and the safety of the environment, the air purifier 5 is fixedly installed on the top of the mixing barrel 2, and the air inlet of the air purifier 5 is connected to a multi-head air inlet pipe, and the multi-head air inlet pipe is connected to the mixing barrel 2 and is arranged with the air purifier 5 as the center.

[0046] Among them, a control panel is arranged at the front position of the top side of the base 1, which is used for controlling the electric heating module 22, motor 1 113, motor 2 301, motor 3 602, motor 4 72, hydraulic cylinder 1 12, hydraulic cylinder 2 63 and electric regulating valve, and a display screen and a control keyboard are arranged on the control panel.

[0047] Working principle: When in use, first turn on the power supply, then start the motor 2 301 and the electric heating module 22, and introduce the asphalt material to be processed from the feed pipe 21 into the mixing barrel 2. The motor 2 301 controls the rotation of the spiral blade 1 32 and the plurality of stirring rods 31 through the rotating shaft 3, so that the asphalt material can be evenly turned over and mixed. The electric heating module 22 heats the asphalt material in the mixing barrel 2 to the required temperature range, and controls the flow rate of the added liquid in the delivery pipe 41 through the electric regulating valve, so that the asphalt material in the storage tank 4 that needs to be filled to the asphalt can be evenly turned over and mixed. The liquid material in the green material is quantitatively transported to the mixing barrel 2 to be mixed with the asphalt. During the rotation of the rotating shaft 3, the scraper 33 can be controlled to move along the bottom inner wall of the mixing barrel 2. At the same time, the spiral blade 2 34 will move along the inner wall of the mixing barrel 2 and clean the asphalt stuck to the wall. Since the spiral direction of the spiral blade 2 34 is opposite to that of the spiral blade 1 32, the spiral blade 2 34 will flip the material downward when the spiral blade 1 32 flips the material upward. At the same time, with the cooperation of multiple stirring rods 31, the asphalt in the mixing barrel 2 can be quickly and evenly mixed.

[0048] When paving is required, the motor 113 is used to control the rotation of the support shaft 111 and the moving wheel 112, so that the device moves to the starting position of the required asphalt paving, and then the motor 4 72, the gear 73 and the gear plate 7 control the hydraulic cylinder 2 63 to drive the cylinder 6 to deflect based on the support frame 61, so as to adjust the width of a single paving, and then the inclination angle of the cylinder 6 is controlled by the hydraulic cylinder to adjust the paving slope, and then the height of the base 1 from the ground is controlled by the hydraulic cylinder 12, so as to adjust the paving thickness during paving, and the two motors 3 602 are started to control the corresponding augers 603 to rotate, and the two augers 603 are transported in opposite directions, and the processed asphalt in the mixing barrel 2 enters the cylinder 6 through the telescopic hose 601 and is paved to both sides by the augers 603. At the same time, during the asphalt paving process, the device can be controlled to maintain a suitable speed.

[0049] During feeding, the rotating baffle 211 will deflect downward by itself and will not hinder the feeding. At the same time, after the feeding is completed, the rotating baffle 211 can be reset and the feeding pipe 21 can be closed under the action of the torsion spring 213. Then, the air purifier 5 can be set to cooperate with the multi-head air intake pipe to suck out and purify the harmful gas in the mixing barrel 2, which can effectively reduce the escape of harmful gas in the mixing barrel 2 during the mixing and stirring of the asphalt material, thereby protecting the health of construction workers and the safety of the environment.
