Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of trench backfilling auxiliary devices, and in particular to a rapid backfilling vehicle. Background Technology
[0002] As we all know, with the advancement of urbanization, road construction is becoming increasingly important. Most roads require the laying of pipelines, and after the pipeline construction is completed, trench backfilling is often necessary.
[0003] Existing technologies have certain shortcomings in trench backfilling: First, the stockpiling of external backfill materials occupies urban roads, affecting normal traffic and easily causing traffic safety hazards; second, the construction efficiency is low, requiring the use of machinery to push the stockpiled soil into the trench, which is time-consuming and labor-intensive; third, the quality cannot be guaranteed, as excessively thick layers of soil pushed into the trench can easily damage pipelines, and the layer thickness is difficult to control, making it difficult to guarantee the compaction degree of the backfill material. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a rapid backfilling vehicle to solve the problems of soil stockpiling occupying urban roads and affecting traffic during the backfilling process; the need for secondary stockpiling of soil before pushing it into the trench, resulting in low construction efficiency; and uneven thickness of soil pushed into the trench, leading to unreliable quality.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid backfilling vehicle, including a cargo box with a V-shaped bottom. A conveying trough is provided at the center of the V-shaped bottom along the length of the cargo box. A first screw conveyor is installed in the conveying trough. The drive end of the first screw conveyor is driven by a motor, and the output end is the unloading end. A receiving hopper is provided directly below the unloading end, and the receiving hopper is detachably fixed to the rear of the cargo box. A second screw conveyor is detachably installed in the receiving hopper. The drive end of the second screw conveyor is driven by a motor, and the output end is the unloading end, which extends outside the cargo box. An unloading port is provided at the rear, enabling the vehicle to unload soil while moving, without occupying the road.
[0006] As a further technical solution, the second screw conveyor is installed in the vertical direction of the first screw conveyor.
[0007] As a further technical solution, the discharge port of the second screw conveyor is fixed with a tail ring in the circumferential direction by multiple fixing rods, and the tail end of the drive shaft inside the second screw conveyor is supported in the tail ring by a bearing.
[0008] As a further technical solution, the three fixing rods are arranged at 120 degrees, and a gap for unloading is evenly left between the fixing rods.
[0009] As a further technical solution, the fixing rod is an equilateral angle steel with a side width of 80mm.
[0010] This invention modifies the bottom of the vehicle compartment into a V-shape and adds a conveying trough. A first screw conveyor is installed in the conveying trough to transport the soil in the compartment to the rear of the compartment. A receiving hopper and a second screw conveyor are installed on the outside of the rear. After the soil transported by the first screw conveyor enters the receiving hopper at the rear, the second screw conveyor in the receiving hopper transfers the soil to the top of the trench, where it is discharged from the unloading port for backfilling.
[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model allows for the unloading of soil while moving, without occupying urban roads or requiring large-scale cleaning operations. This reduces the frequency of manual cleaning of urban roads and ensures environmentally friendly construction.
[0012] 2. The backfill material of this utility model is directly backfilled into the pipeline trench by a screw conveyor, which improves work efficiency, eliminates the need to use machinery to push the backfill material into the pipeline trench again, and reduces construction costs.
[0013] 3. The backfilling vehicle of this utility model can unload backfill material evenly, avoiding concentrated soil entering the trench and damaging the constructed pipelines. It can also control the thickness of each layer, ensuring layered backfilling. Layered backfilling avoids damage to pipelines from excessively thick layers, and the layer thickness is easy to control, reducing the amount of manual secondary leveling work and ensuring the compaction of each layer.

[0021] 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.
[0022] Example: Reference Figure 1-5 The illustrated rapid backfill vehicle includes a cargo box 1 with a V-shaped bottom. A conveying trough 11 is located at the center of the V-shaped bottom along the length of the cargo box. A first screw conveyor 2 is installed inside the conveying trough 11. The drive end of the first screw conveyor 2 is driven by a motor 3, and its output end is a discharge end. A receiving hopper 12 is located directly below the discharge end and is detachably fixed to the rear of the cargo box 1. A second screw conveyor 4 is detachably installed inside the receiving hopper 12 and is perpendicular to the first screw conveyor 2. The drive end of the second screw conveyor 4 is driven by a motor 3, and its output end is a discharge end that extends 2m beyond the outer edge of the cargo box 1. A discharge port 41 is located at the rear of the second screw conveyor 4.
[0023] like Figure 3-5 As shown, the discharge port 41 of the second screw conveyor 4 is fixed with a tail ring 6 in the circumferential direction by three fixed rods 7 arranged at 120 degrees. The tail end of the drive shaft 42 inside the second screw conveyor 4 is supported in the tail ring 6 by a bearing 5.
[0024] Furthermore, the fixing rod 7 is an equilateral angle steel with a side width of 80mm.
