Description

Technical Field

[0001] The present invention relates to the technical field of waste utilization, in particular to a novel composite material and a temporary road construction device. Background Art

[0002] When constructing roads (such as national highways and expressways) and large-scale infrastructure, it is often necessary to first excavate and remove the soil from the ground. (If the excavated soil is not removed quickly, it will accumulate over time and become a source of pollution.) This is then used as a foundation for the construction of the main facilities. In addition to the construction of the main facilities, temporary access roads are often required for the passage of labor, equipment, machinery, and construction vehicles. The construction standards for access roads vary depending on the purpose. Common access roads are constructed primarily using conventional building materials such as sandstone and concrete. While these materials offer adequate performance, they are wasteful for low-demand, low-standard applications, and their subsequent demolition is cumbersome and costly.

[0003] Using waste soil excavated during construction to build temporary walkways could be a viable solution. Mixing the soil with sand and gravel particles and laying it directly on the ground creates a temporary artificial walkway. This approach is both cost-effective and an effective way to utilize waste soil. However, large chunks of soil are difficult to use directly and must be crushed into small particles or chunks before being mixed with sand and gravel. However, bulky soil has a high water content and high viscosity, making it difficult for conventional crushing equipment to handle this process. Therefore, a more efficient device is needed to fully utilize waste soil resources. Summary of the Invention

DETAILED DESCRIPTION

[0018] Example 1 The following is further explained in conjunction with specific embodiments. This embodiment provides a new composite material for the construction of temporary access roads, including soil particles and sand and gravel particles; the volume ratio of a single soil particle to a single sand and gravel particle is 2:1; and the mass ratio of soil particles to sand and gravel particles is 1.5:1.

[0019] Example 2 As attached Figure 1 -Attached Figure 12As shown, this embodiment provides a temporary road construction device based on the new composite material of Example 1, including a vehicle body 10, a crushing device 20 provided above one end of the vehicle body 10, a mixing device 30 provided below the crushing device 20, a first feeding device 40 provided on the vehicle body 10 and connected to the crushing device 20, and a second feeding device 50 provided on the vehicle body 10 and connected to the mixing device 30; soil particles are stored in the first feeding device 40, and sand and gravel particles are stored in the second feeding device 50. Specifically, the soil blocks excavated during the road construction process are crushed and mixed with sand and gravel, and then spread on the ground. After being flattened by a roller, it can be used as a temporary walkway. In the short term, since the walkway contains a sufficient amount of sand and gravel, it has sufficient stability and support to support the passage of pedestrians and small-weight equipment. In addition, the soil itself has a certain adhesiveness, which can gather the sand and gravel together, eliminating the need for or significantly reducing the use of cement. In addition, the excavated waste soil can be effectively utilized to reduce the transportation cost of the waste soil. In addition, when the project is demolished in the later stage, since there is no need for cement, the walkway can also be efficiently demolished, thereby improving the overall construction efficiency and reducing the project cost. The newly excavated waste soil can be directly fed into the first feeding device 40, and then fed into the crushing device 20 to be crushed into smaller and more uniform particles, making it easier to mix with the sand and gravel particles. The sand and gravel particles can be fed into the second feeding device 50, and then fed into the mixing device 30 to be fully mixed with the crushed soil particles. The above-mentioned devices can be directly installed on a conventional four-wheel structure (or crawler structure) vehicle body 10, and then directly laid on the ground after crushing and mixing to form a temporary access road, making the entire road paving process more convenient and eliminating the need for frequent transfer of raw materials. In addition, the vehicle body 10 itself can have a self-contained drive system (i.e., it can move and turn under the control of the operator, and it can be driven by a conventional motor or engine), or it can use an external power device such as a trolley to pull the vehicle body 10 along the trajectory of the access road to be laid, and the access road can be laid during the movement. After the access road is paved, it is necessary to use equipment such as a roller to compact and level the road surface.

[0020] The crushing device 20 in this embodiment includes a shell 21 vertically arranged on the vehicle body 10, a plurality of fixed blocks 24 arranged on the inner wall of the shell 21 close to the vehicle body 10, a feed port 22 opened at the upper end of the shell 21, a discharge port 23 opened at the lower end of the shell 21 away from the vehicle body 10, a hollow crushing roller 25 horizontally rotatably arranged in the shell 21, a plurality of crushing blocks 26 arranged on the side walls of the crushing roller 25, and a first driving device 60 for driving the crushing roller 25 to rotate; the plurality of fixed blocks 24 are evenly distributed in the horizontal direction; along the horizontal direction, the fixed blocks 24 and the crushing blocks 26 are alternately distributed; both ends of the crushing roller 25 are rotatably connected to the side walls of the shell 21, and the axial direction of the crushing roller 25 is perpendicular to the length direction of the vehicle body 10. Specifically, after large pieces of soil enter the shell 21 through the feed port 22, the first drive device 60 drives the crushing roller 25 to rotate, and during the rotation of the crushing roller 25, the crushing block 26 is driven to rotate. Through the action of the crushing block 26 and the fixed block 24, the large pieces of soil can be squeezed and cut into small pieces, and then fall into the mixing device 30 below the shell 21 to be mixed with sand and gravel particles.

[0021] The crushing device 20 in this embodiment also includes a plurality of through holes 27 opened on the side wall of the crushing roller 25, a plurality of sliding tubes 28 provided on the inner wall of the crushing roller 25, an adjustment block 210 horizontally provided in the crushing roller 25, and a connecting rod 211 for connecting the adjustment block 210 and the shell 21; a sliding tube 28 is fixedly provided at a through hole 27, and a crushing block 26 is slidably provided in a sliding tube 28; the length direction of the adjustment block 210 is parallel to the axial direction of the crushing roller 25; the upper side of the adjustment block 210 is a convex arc surface, and the lower side of the adjustment block 210 is a flat surface; the arc surface of the adjustment block 210 is arranged close to the upper side of the inner wall of the crushing roller 25, and the arc surface of the adjustment block 210 is arranged close to the inner wall of the crushing roller 25 on the side close to the vehicle body 10; the connecting rod 211 is connected to the end of the adjustment block 210. Specifically, by providing the structure of the through hole 27 and the slide tube 28, the crushing block 26 can move in the through hole 27 and the slide tube 28, that is, the crushing block 26 can protrude from the outer surface of the crushing roller 25, or can be completely located inside the slide tube 28. Its function is as follows: since the upper side of the adjustment block 210 is an arc-shaped surface and is arranged close to the side of the vehicle body 10, when the crushing block 26 on the crushing roller 25 rotates to approach the adjustment block 210, the crushing block 26 will be gradually pushed out of the slide tube 28 by the adjustment block 210 from the moment it contacts the adjustment block 210 (that is, the crushing block 26 protrudes from the outside of the crushing roller 25). At this time, the crushing block 26 and the fixed block 24 can play a crushing role. When the crushing block 26 continues to rotate until it leaves the arc-shaped surface of the adjustment block 210, the crushing block 26 loses the squeezing effect of the adjustment block 210, and the crushing block 26 continues to rotate until it contacts the inner wall of the shell 21 (attached). Figure 5 and attached Figure 7(The housing 21 is shown as open-sided for ease of illustration; it is actually closed-sided.) The shredder 26 is squeezed into the slide tube 28 by the inner wall of the housing 21. The high-water content dirt adhering to the outer wall of the shredder 26 is then scraped off and falls to the lower end of the housing 21. Each shredder 26 undergoes a contraction and expansion process with each rotation, effectively scraping away dirt adhering to the shredder 26.

[0022] The pulverizing device 20 in this embodiment further includes a plurality of horizontally arranged connecting plates 29 distributed along the circumference of the pulverizing roller 25. The connecting plates 29 are used to connect one end of a plurality of pulverizing blocks 26 located in a straight line within the pulverizing roller 25. Specifically, the connecting plates 29 serve to improve the consistency of movement of the pulverizing blocks 26 in the straight line and prevent the pulverizing blocks 26 from dislodging from the slide tube 28.

[0023] The mixing device 30 in this embodiment includes a feed pipe 35 connected to the side of the shell 21 close to the vehicle body 10; the feed pipe 35 is a flat structure arranged at an angle, and the feed pipe 35 is connected to the second feeding device 50; the mixing device 30 also includes a first rotating shaft 31 horizontally arranged at the lower end of the inside of the shell 21 close to the side of the vehicle body 10, a plurality of stirring blades 32 connected to the first rotating shaft 31, a second rotating shaft 33 horizontally arranged inside the shell 21 close to the discharge port 23, a plurality of levers 34 connected to the second rotating shaft 33, and a second driving device 70 for driving the first rotating shaft 31 and the second rotating shaft 33 to rotate; the axial direction of the first rotating shaft 31 and the axial direction of the second rotating shaft 33 are both parallel to the axial direction of the crushing roller 25; both ends of the first rotating shaft 31 and the second rotating shaft 33 are rotatably connected to the side wall of the shell 21. Specifically, after the sand and gravel particles are fed into the housing 21 through the feed pipe 35 , the soil particles and the sand and gravel particles can be stirred and mixed by the stirring blade 32 and the shifting rod 34 , and the mixed materials are naturally discharged through the discharge port 23 .

[0024] In this embodiment, the length direction of the lever 34 is parallel to the length direction of the second rotating shaft 33, and multiple levers 34 are distributed in a circular pattern outside the second rotating shaft 33. During the rotation of the second rotating shaft 33 and the crushing roller 25, the lever 34 abuts against the lower side of the outer wall of the crushing roller 25. The linear velocity of the outer wall of the crushing roller 25 is the same as the linear velocity of the side of the lever 34 away from the second rotating shaft 33. The mixing device 30 also includes a scraper 212 horizontally arranged on the lower side of the shell 21 near the discharge opening 23. The scraper 212 abuts against the outer wall of the crushing roller 25 near the discharge opening 23. Both ends of the scraper 212 are fixedly connected to the inner wall of the shell 21. Specifically, the rotation of the second rotating shaft 33 drives the lever 34 to rotate. The rotation of the lever 34 facilitates the mixing of soil particles and sand and gravel particles and also promotes the discharge of soil particles and sand and gravel particles from the discharge opening 23. In addition, the lever 34 will periodically contact the crushing block 26 and squeeze the crushing block 26 into the slide tube 28 (as shown in the attached figure). Figure 6 As shown, the second rotating shaft 33 rotates in the opposite direction to the crushing roller 25). When the crushing block 26 is pressed into the slide tube 28, the scraper 212 can scrape off the soil adhering to the outer wall of the crushing roller 25 and the end of the crushing block 26 to prevent it from adhering for a long time.

[0025] In this embodiment, the first drive device 60 includes a first motor 61 fixed to the side wall of the housing 21, a first driving pulley 62 provided on the output shaft of the first motor 61, and a first transmission belt 63 for connecting the first driving pulley 62 and the crushing roller 25. The second drive device 70 includes a second motor 71 fixed to the lower side of the housing 21, a second driving pulley 72 provided on the output shaft of the second motor 71, a first driven pulley 73 provided at the end of the first rotating shaft 31, a second driven pulley 74 provided at the end of the second rotating shaft 33, and a second transmission belt 75 for simultaneously connecting the second driving pulley 72, the first driven pulley 73, and the second driven pulley 74. Specifically, the rotation of the crushing roller 25, the first rotating shaft 31, and the second rotating shaft 33 is mainly driven by the motor and the transmission belt (which requires a tensioning pulley), but can also be driven by a chain, gear, or other means.

[0026] In this embodiment, the first feeding device 40 includes a conical first hopper 41 provided on the vehicle body 10, a first conveyor belt 42 inclined within the first hopper 41, and a feed plate 43 inclined above the vehicle body 10; the upper end of the feed plate 43 is located below the upper end of the first conveyor belt 42, and the lower end of the feed plate 43 is located above the feed port 22. The second feeding device 50 includes a conical second hopper 51 provided on the vehicle body 10, and a second conveyor belt 52 inclined within the second hopper 51; the upper end of the second conveyor belt 52 is located above the feed pipe 35. Specifically, the first conveyor belt 42 feeds large lumps of soil from the first hopper 41 onto the feed plate 43, where they naturally slide down into the housing 21 for crushing. The second conveyor belt 52 feeds sand and gravel particles from the second hopper 51 into the feed pipe 35, where they naturally slide down to the lower end of the housing 21 and mix with the soil particles. Baffle-like mechanisms can be provided on both the first conveyor belt 63 and the second conveyor belt 52 to better transport materials.

[0027] This embodiment also includes a water spray device 80 mounted on the vehicle body 10. The water spray device 80 comprises a water spray pipe 81 horizontally positioned below the discharge port 23, a plurality of nozzles 82 disposed on the sides of the water spray pipe 81, a water supply pipe 83 connected to the water spray pipe 81, a water pump connected to the water supply pipe 83, and a water storage tank 84 mounted on the vehicle body 10. The water pump is disposed in the water storage tank 84. Specifically, the water pump delivers water from the water tank through the water supply pipe 83 into the water spray pipe 81, where it is sprayed through the nozzles 82. The sprayed water is then directly sprayed onto the material discharged from the discharge port 23, moistening the material to a certain extent and improving the efficiency of subsequent compaction.
