Description

Technical Field

[0001] This utility model relates to the technical field of roadbed filling construction equipment, and in particular to a layered filling device for highway roadbeds. Background Technology

[0002] Layered filling of highway subgrade is a common construction method. By spreading and compacting the subgrade material in layers, the density, stability and bearing capacity of the subgrade are ensured. Depending on the properties of the subgrade material and the compaction equipment, the thickness of each layer is generally controlled at 20-30cm, and the compaction thickness is not less than 10cm. During construction, bulldozers or graders are used to spread the subgrade material evenly to ensure that the subgrade material is evenly distributed.

[0003] Chinese Patent Publication No. CN218405365U discloses a highway subgrade layered filling device, including a drive vehicle. A height adjustment mechanism is fixedly installed on the side of the drive vehicle via a connecting block. A compaction mechanism is fixedly installed on the moving end of the height adjustment mechanism. The height adjustment mechanism includes a connecting shell, which is fixedly installed on the side of the connecting block. A stepper motor is fixedly installed on the top of the connecting shell. The output shaft of the stepper motor passes through the connecting shell and extends into it, where a first screw is fixedly connected. A lifting block is threaded onto the surface of the first screw. The left side of the lifting block passes through the connecting shell and extends outward. This highway subgrade layered filling device has a reasonable structural design and is easy to use. It can not only adjust the height of the subgrade layered filling and then flatten it, but also adjust the compaction area according to its width, making it highly applicable and fully meeting usage requirements.

[0004] The above-mentioned technology can only achieve the effect of compacting roadbeds at different heights, but cannot realize the paving operation of roadbeds at different heights. Manual paving requires repeated setting out and measurement, which is inefficient. Therefore, this utility model discloses a layered filling device for roadbeds to solve the above problems. Utility Model Content

[0010] As a further embodiment of this utility model, the lifting assembly includes a screw rotatably embedded in the bottom wall of the guide groove and a transmission shaft rotatably embedded between two opposing cavity walls of the transmission cavity. Both ends of the transmission shaft extend out of the frame and are fixed with handles.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model discloses a layered filling device for highway subgrade. When the handle is turned, the handle drives the transmission shaft to rotate, which in turn drives a bevel gear to rotate. The bevel gear meshes with and transmits the rotation of a second bevel gear, which in turn drives a screw to rotate. The screw drives the slider to move up and down by means of a threaded structure. The height of the material distribution box can be adjusted according to the construction thickness of different layers of the highway subgrade. Since the distance from the discharge port to the subgrade surface is constant, the amount of concrete discharged can be effectively limited, so that the thickness of each layer of concrete is consistent and no manual leveling is required.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Please see Figure 1-5 This utility model provides a layered filling device for highway subgrade, including a frame 1 that can move along the highway subgrade. The lower sides of both ends of the frame 1 are fixed with movable chambers 14. The bottom of the movable chambers 14 has an opening, and two traveling wheels 15 are rotatably connected between the inner walls on both sides of the opening.

[0027] Specifically, the design of the traveling wheels 15 enables the entire device to move in a straight line on the roadbed, facilitating layered filling operations along the roadbed.

[0028] Furthermore, two connecting plates 16 are fixedly connected to one side of the frame 1, and each connecting plate 16 is provided with multiple assembly holes;

[0029] Specifically, the assembly hole can be used to bolt the frame 1 to the concrete pump truck, so that the frame 1 can be towed forward by the concrete pump truck. It is worth noting that when filling roadbed materials such as sand, gravel and soil, it is necessary to use equipment such as tractors for traction, and rely on trucks traveling at the same speed as the tractors and belt conveyors on the trucks to inject materials into the feed hopper 32.

[0030] Furthermore, a lifting assembly 2 is installed inside the frame 1. The lifting assembly 2 includes a screw 21 rotatably embedded in the bottom wall of the guide groove 11 and a transmission shaft 22 rotatably embedded between two opposing cavity walls of the transmission cavity 12. Both ends of the transmission shaft 22 extend out of the frame 1 and are fixed with handles 23. Both outer sides of both ends of the transmission shaft 22 are fixed with bevel gear 24. The top of the screw 21 is fixed with bevel gear 25. Both bevel gears 25 are meshed with the adjacent bevel gear 24.

[0031] Specifically, rotating the handle 23 causes the transmission shaft 22 to rotate, which in turn drives the first bevel gear 24 to rotate. The first bevel gear 24 meshes with and transmits the rotation of the second bevel gear 25, which in turn drives the screw 21 to rotate. The screw 21 drives the slider 31 to move up and down using its threaded structure. The height of the material distribution box 3 can be adjusted according to the construction thickness of different layers of the roadbed.

[0032] Furthermore, both ends of the material equalization box 3 are fixed with sliders 31, the sliders 31 can slide along the adjacent guide grooves 11, and the sliders 31 are threadedly connected to the adjacent screws 21.

[0033] Specifically, the slider 31 slides up and down along the guide groove 11 to provide a stable guide path for the lifting and lowering movement of the equalization box 3, ensuring that the equalization box 3 maintains vertical movement during the lifting and lowering process and does not deviate.

[0034] Furthermore, a material equalization box 3 is installed on the lifting assembly 2, and a material equalization assembly 4 is installed inside the material equalization box 3. The material equalization assembly 4 includes a rotating shaft 41 rotatably connected between the inner walls of both sides of the material equalization box 3 and a drive motor 42 fixedly connected to the outer wall of one side of the material equalization box 3. The output end of the drive motor 42 is fixedly connected to the rotating shaft 41. A material roller 43 is fixedly sleeved on the outer side of the middle part of the rotating shaft 41. Multiple spiral blades 44 with opposite directions are respectively provided on the outer sides of both ends of the material roller 43. Multiple stirring rods 45 are provided on the outer wall of the material roller 43 and between adjacent spiral blades 44.

[0035] Specifically, the drive motor 42 drives the material roller 43 to rotate, and the spiral blades 44 spread the concrete evenly to both sides, so that the concrete can be discharged evenly from the discharge port 33. At the same time, the mixing rod 45 continuously turns the concrete at the discharge port 33, which can prevent the concrete from blocking and avoid the inefficiency and unevenness of manual leveling, thereby improving construction efficiency and the quality of roadbed filling.

[0036] Furthermore, guide grooves 11 are provided on both opposite side walls of the frame 1, and a transmission cavity 12 is connected between the two guide grooves 11. A clearance groove 13 is provided on the frame 1 and below the guide grooves 11, and the drive motor 42 is located in one of the clearance grooves 13.

[0037] Specifically, the design of the clearance groove 13 provides installation space for the drive motor 42 and other components, avoiding interference between components. This allows the frame 1 to not only provide guidance and transmission functions for the lifting assembly 2, but also to provide installation space for the drive motor 42, thus realizing the multi-functional integration of the filling device.

[0038] Furthermore, a feeding hopper 32 is fixedly embedded in the middle of one side of the material equalization box 3, and a discharge port 33 is provided at the bottom of the material equalization box 3, the width of the discharge port 33 gradually narrows from top to bottom;

[0039] Specifically, the design of the feed hopper 32 allows the roadbed material to enter the uniform material box 3 smoothly, while reducing the impact on the internal structure. It is worth noting that the feed hopper 32 is located in the middle of the uniform material box 3, which makes it easy for the spiral blades 44 to spread the roadbed material evenly to both sides. The gradually narrowing design can effectively control the discharge speed and amount of the material, which helps to ensure that the thickness of each layer of filling is uniform.

[0040] Working principle:

[0041] Before construction, turn the handle 23. The handle 23 drives the transmission shaft 22 to rotate. The transmission shaft 22 drives the first bevel gear 24 to rotate. The first bevel gear 24 meshes with and transmits the second bevel gear 25 to rotate. The second bevel gear 25 drives the screw 21 to rotate. The screw 21 drives the slider 31 to move up and down by means of the thread structure. The height of the material distribution box 3 can be adjusted according to the construction thickness of different layers of the roadbed.

[0042] During construction, the frame 1 is connected to the rear of the concrete pump truck, allowing it to move forward with the truck. The truck continuously injects concrete into the feed hopper 32, while the drive motor 42 rotates the material roller 43. The spiral blades 44 spread the concrete evenly to both sides, ensuring that the concrete is discharged uniformly from the discharge port 33. Simultaneously, the mixing rod 45 continuously agitates the concrete at the discharge port 33, preventing blockage. It is worth noting that since the distance from the discharge port 33 to the roadbed surface is constant, this effectively limits the amount of concrete discharged, ensuring that each layer of concrete is laid to a uniform thickness, eliminating the need for manual leveling.
