Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a device for uniformly distributing crushed stone for road base construction. Background Technology

[0002] The road base course is a crucial layer in the road structure system, connecting the upper and lower layers. Its main function is to bear the vehicle loads transmitted from the surface layer and spread them to the subgrade. Due to its good permeability and deformation resistance, graded crushed stone is widely used in the construction of flexible base courses and subbase courses. The quality of base course construction, especially the uniformity and density of crushed stone spreading, directly determines the overall strength, smoothness and service life of the road.

[0003] Most existing cement-stabilized crushed stone paving devices can only spread cement-stabilized crushed stone, and do not guarantee the uniformity of the cement-stabilized crushed stone base after spreading. During the compaction process, unevenness caused by uneven material distribution is likely to occur, so manual repair is required afterward, which is time-consuming and labor-intensive. The existing patent (publication number: CN219157326U) discloses a cement-stabilized crushed stone paving device for road base construction, which relates to the technical field of road base construction. It includes a machine body and a funnel-shaped hopper. The hopper is set on the machine body, and the machine body is provided with a discharge channel for connecting the bottom of the hopper and the bottom of the machine body. The discharge channel is inclined and a discharge mechanism is provided in the discharge channel. A leveling component for leveling the cement-stabilized crushed stone is provided on the side of the machine body near the bottom of the discharge channel. This application achieves uniform paving of cement-stabilized crushed stone by setting a paving device that can level the cement-stabilized crushed stone, effectively reducing the labor intensity of construction personnel in the later stage, and thus helping to improve construction efficiency.

[0004] To address the aforementioned issues, existing patents have provided solutions. However, using a flat plate to level the laid gravel can only level excess gravel, and cannot effectively level low-lying areas and excess protruding gravel, resulting in an inability to achieve effective and uniform distribution of gravel.

[0005] To address this, a device for uniformly distributing crushed stone in road base construction is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a crushed stone uniform distribution device for road base construction, which can solve the problem that existing crushed stone paving devices cannot effectively level low-lying areas and excess protruding crushed stones, resulting in the inability to effectively distribute crushed stones evenly.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a uniform crushed stone distribution device for road base construction, comprising an installation base, a storage bin at the top of the installation base, a distribution port at the bottom of the storage bin, an adjustable leveling mechanism on one side of the installation base, and a uniform distribution mechanism at the bottom of the storage bin. The adjustable leveling mechanism includes a hydraulic push rod disposed on the top of the mounting base. An adjustment plate is disposed at the output end of the hydraulic push rod. Two bearing seats are disposed at the bottom of the adjustment plate. The two bearing seats are inclined. A rotating shaft is disposed inside the bearing seats. A spiral auger is disposed on the side wall of the rotating shaft. A drive assembly is disposed at one end of the rotating shaft.

[0008] Preferably, the drive assembly includes a drive motor disposed on the top of the adjustment plate, and a drive wheel is disposed at one end of both the drive motor and the rotating shaft, and a drive belt is disposed between the two drive wheels.

[0009] Preferably, the uniform speed fabric feeding mechanism includes an adjusting cylinder disposed in the middle of the fabric feeding opening, an adjusting rod rotatably connected to the middle of the adjusting cylinder, a plurality of adjusting wheels disposed on the side wall of the adjusting rod, a plurality of partitions disposed on the side wall of the adjusting wheels, a servo motor bolted to the side wall of the adjusting cylinder, and the output end of the servo motor being fixedly connected to the adjusting rod.

[0010] Preferably, the tail of the adjusting plate is provided with a scraper, and the bottom of the scraper is inclined.

[0011] Preferably, a plurality of sleeves are provided on the side wall of the mounting base, and a movable plate is movably disposed inside the sleeve. The movable plate is bolted to the sleeve, and a movable wheel is connected to the bottom bearing of the movable plate.

[0012] Preferably, a vibration motor is bolted to the side wall of the storage silo.

[0013] Preferably, a pusher plate is provided on the side wall of the scraper, and the pusher plate is V-shaped.

[0014] Preferably, the top of the adjustment plate is provided with multiple stabilizing rods, which are movably connected to the mounting base.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This application incorporates an adjustable leveling mechanism. The auger of this adjustable leveling mechanism is inclined, which can achieve the leveling and compaction of crushed stone during rotation, further improving the uniformity of crushed stone distribution on the base layer. At the same time, it can better adapt to crushed stone of different particle sizes and shapes, ensuring the flatness and density of the base layer. By adjusting the height of the auger through the hydraulic push rod, it can achieve uniform distribution and leveling of crushed stone of different thicknesses.

[0016] 2. This application incorporates a uniform speed material distribution mechanism. In this process, the uniform speed material distribution mechanism precisely controls the rotation speed of the adjusting wheel through a servo motor, so that the crushed stone can be distributed from the material distribution port at a uniform speed.

[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. 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.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: A uniform crushed stone distribution device for road base construction includes an installation base 1, a storage bin 2 at the top of the installation base 1, a distribution port 3 at the bottom of the storage bin 2, an adjustable leveling mechanism 4 on one side of the installation base 1, and a uniform distribution mechanism 5 at the bottom of the storage bin 2. The adjustable leveling mechanism 4 includes a hydraulic push rod 41 disposed on the top of the mounting base 1. An adjustment plate 42 is disposed at the output end of the hydraulic push rod 41. Two bearing seats 43 are disposed at the bottom of the adjustment plate 42. The two bearing seats 43 are inclined. A rotating shaft 44 is disposed inside the bearing seat 43. A spiral auger 45 is disposed on the side wall of the rotating shaft 44. A drive assembly 46 is disposed at one end of the rotating shaft 44.

[0022] Specifically, such as Figure 2 As shown, the drive assembly 46 includes a drive motor 461 disposed on the top of the adjustment plate 42. One end of the drive motor 461 and the rotating shaft 44 are both provided with a transmission wheel 462, and a transmission belt 463 is disposed between the two transmission wheels 462.

[0023] Specifically, such as Figure 4 As shown, a scraper 6 is provided at the tail of the adjusting plate 42, and the bottom of the scraper 6 is inclined.

[0024] Specifically, such as Figure 3 As shown, multiple sleeves 7 are provided on the side wall of the mounting base 1. A movable plate 8 is movably arranged inside the sleeve 7. The movable plate 8 is bolted to the sleeve 7. The bottom bearing of the movable plate 8 is connected to a movable wheel 9.

[0025] Specifically, such as Figure 3 As shown, a pusher plate 11 is provided on the side wall of the scraper 6, and the pusher plate 11 is V-shaped.

[0026] Specifically, such as Figure 4 As shown, the top of the adjustment plate 42 is provided with multiple stabilizing rods 12, which are movably connected to the mounting base 1.

[0027] In use, the crushed stone is first loaded into the storage bin 2 at the top of the mounting base 1. When construction begins, the uniform speed spreading mechanism 5 at the bottom of the storage bin 2 is activated, causing the crushed stone to be scattered from the spreading port 3 at a uniform speed, thus achieving the initial spreading operation. At the same time, the adjustable leveling mechanism 4 on one side of the mounting base 1 starts to work. The hydraulic push rod 41 pushes the adjusting plate 42 down to a suitable height. The drive motor 461 transmits power to the rotating shaft 44 through the transmission wheel 462 and the transmission belt 463, causing the rotating shaft 44 to drive the spiral auger 45 to rotate. Because the two bearing seats 43 are inclined... The inclined spiral auger 45, during its rotation, not only evenly spreads the crushed stone but also exerts downward pressure, helping it to better embed into the base layer, increasing its density, and ensuring a more uniform distribution. The hydraulic push rod 41, acting as a power source, drives the adjusting plate 42 up and down through its extension and retraction. The height of the adjusting plate 42 can be flexibly adjusted according to the requirements of the road base construction and the distribution of the crushed stone, thus changing the distance between the spiral auger 45 and the ground to ensure the leveling effect meets design standards. The scraper 6 at the tail of the adjusting plate 42 is inclined at the bottom; during leveling, the scraper 6 can scrape away excess crushed stone, further ensuring the flatness of the base surface. The V-shaped pusher 11 on the side wall of the scraper 6 can evenly disperse the crushed stone in the middle to both sides during forward movement. The sleeve 7 on the side wall of the mounting base 1 cooperates with the moving plate 8; by adjusting the position of the moving plate 8 within the sleeve 7, the height of the moving wheel 9 can be changed, thereby adjusting the tilt angle of the entire device, ensuring stable operation under different terrain conditions. The stabilizing rod 12 serves as... The adjustment plate 42 enhances stability and prevents it from shaking during operation. The adjustable leveling mechanism 4, with its inclined auger 45, compacts and levels the crushed stone during rotation, further improving the uniformity of stone distribution on the base layer. It also better accommodates crushed stone of different sizes and shapes, ensuring the flatness and density of the base layer. The hydraulic push rod 41 adjusts the height of the auger 45, enabling uniform distribution and leveling of crushed stone of varying thicknesses.

[0028] Specifically, such as Figure 4 As shown, the uniform speed fabric feeding mechanism 5 includes an adjusting cylinder 51 located in the middle of the fabric feeding port 3. An adjusting rod 52 is rotatably connected to the middle of the adjusting cylinder 51. Multiple adjusting wheels 53 are provided on the side wall of the adjusting rod 52. Multiple partitions 54 are provided on the side wall of the adjusting wheels 53. A servo motor 55 is bolted to the side wall of the adjusting cylinder 51. The output end of the servo motor 55 is fixedly connected to the adjusting rod 52.

[0029] Specifically, such as Figure 2 As shown, a vibration motor 10 is bolted to the side wall of the storage bin 2.

[0030] In use, the servo motor 55 drives the adjusting rod 52 to rotate, and the adjusting rod 52 drives the adjusting wheel 53 to rotate. Multiple baffles 54 on the adjusting wheel 53 divide the internal space of the adjusting cylinder 51 into multiple relatively independent small areas. When the adjusting wheel 53 rotates, the crushed stone enters these small areas in sequence and is evenly distributed from the distribution port 3 under the push of the baffles 54. By controlling the rotation speed of the servo motor 55, the rotation speed of the adjusting wheel 53 can be precisely adjusted, thereby controlling the distribution speed of the crushed stone and achieving uniform distribution. The vibration motor can effectively prevent the crushed stone from clogging in the storage bin 2 and ensure the continuous operation of the uniform distribution mechanism 5. Thus, through the setting of the uniform distribution mechanism 5, the uniform distribution mechanism 5 precisely controls the rotation speed of the adjusting wheel 53 through the servo motor 55, so that the crushed stone can be distributed from the distribution port 3 at a uniform speed, avoiding the problem of inconsistent base thickness caused by uneven distribution speed in traditional distribution methods, and providing a basic guarantee for the uniformity of the road base.

[0031] By adopting the above technical solution, the problem that existing crushed stone paving devices cannot effectively level low-lying areas and excess protruding crushed stones, resulting in the inability to effectively and evenly distribute the crushed stones, is solved.

[0032] Working Principle: In use, the crushed stone is first loaded into the storage bin 2 at the top of the mounting base 1. The servo motor 55 drives the adjusting rod 52 to rotate, which in turn drives the adjusting wheel 53 to rotate. Multiple baffles 54 on the adjusting wheel 53 divide the internal space of the adjusting cylinder 51 into several relatively independent small areas. When the adjusting wheel 53 rotates, the crushed stone enters these small areas in sequence and is evenly distributed from the feeding port 3 under the push of the baffles 54. By controlling the rotation speed of the servo motor 55, the rotation speed of the adjusting wheel 53 can be precisely adjusted, thereby controlling the feeding speed of the crushed stone and achieving uniform feeding. The vibration motor can effectively prevent the crushed stone from clogging in the storage bin 2. The adjustable leveling mechanism 4 on one side of the mounting base 1 starts to work. The hydraulic push rod 41 pushes the adjusting plate 42 down to a suitable height. The drive motor 461 transmits power to the rotating shaft 44 through the transmission wheel 462 and the transmission belt 463, causing the rotating shaft 44 to rotate. The auger 45 rotates, and because the two bearing seats 43 are inclined, the auger 45 can not only spread the crushed stone evenly during rotation, but also exert a certain downward pressure on the crushed stone, which helps the crushed stone to better embed into the base layer, improve the density of the base layer, and make the crushed stone more evenly distributed on the road base layer. The hydraulic push rod 41 serves as a power source, and through the extension and retraction of its output end, it drives the adjusting plate 42 to move up and down. According to the requirements of the road base construction and the spreading of crushed stone, the height of the adjusting plate 42 can be flexibly adjusted, thereby changing the distance between the auger 45 and the ground, ensuring that the leveling effect meets the design standards. The scraper 6 at the tail of the adjusting plate 42 is inclined at the bottom. During the leveling process, the scraper 6 can scrape off excess crushed stone, further ensuring the flatness of the base layer surface. The V-shaped push plate 11 on the side wall of the scraper 6 can evenly disperse the crushed stone in the middle to both sides during the forward movement.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
