Description

Technical Field

[0001] The invention relates to the technical field of soil spreading, in particular to a soil spreading device and a construction method for layered filling of lime-soil improved soil roadbed. Background Art

[0002] The effect of layered filling of lime-soil improved soil roadbed is mainly reflected in enhancing the overall performance and stability of the roadbed. Through layered filling, it can be ensured that each layer of soil or filler can reach the specified compaction degree, thereby improving the density and uniformity of the roadbed. As a high-quality roadbed filler, the stability and strength of lime-soil improved soil are significantly improved, and it can effectively resist the influence of external loads and the natural environment. In addition, layered filling also helps to control the construction quality, facilitates the timely discovery and treatment of potential problems, and thus ensures the safety and durability of the road.

[0003] In the process of layered filling of the lime-soil improved soil roadbed, soil spreading is a crucial step. The purpose of spreading is to lay the soil evenly and flatly on the roadbed to lay the foundation for subsequent compaction work. The quality and uniformity of paving directly affect the overall performance of the roadbed and the service life of the road surface. At present, bulldozers are often used in the prior art to rough-level the filling materials, but the paving area that can be covered by a single operation of a traditional bulldozer is relatively small. When faced with large-scale paving tasks, multiple repeated operations have to be adopted, which not only significantly increases the construction time, but may also lead to low work efficiency. In addition, conventional bulldozers are not convenient for multi-layer uniform paving, and local accumulation or missing materials may occur, resulting in uneven distribution of materials, which in turn affects the stability and bearing capacity of the roadbed. What is particularly critical is that these bulldozers often lack flexible reciprocating movement capabilities during paving operations, which limits the continuity and uniformity of the paving operations, thereby affecting the final construction effect, resulting in uneven road surface quality and difficulty in meeting high-standard construction requirements. Therefore, it is of great significance to study a new soil paving device and construction method for layered filling of gray-soil improved soil roadbed to solve the above-mentioned problem domain.

The regulating component 201 includes two groups of regulating structures 2011 and an assembly plate 2012. The position of the adjustable shovel plates 206 can be adjusted through the regulating structures 2011 to meet the needs of soil paving. The two groups of regulating structures 2011 are assembled on the front and rear sides of the bulldozer 100. The number of each group of regulating structures 2011 is two and they are cross-arranged. Two regulating structures 2011 are installed on the assembly plate 2012. The regulating component 201 is connected to one of the adjustable shovel plates 206. The adjustable shovel plate 206 includes a guide rail 2061. The other two regulating structures 2011 are installed on one of the guide rails. On the rail 2061, the guide rail 2061 and the fixed shovel plate 205 are both provided with a slide groove 204, and the guide rail 2061 is provided with a slide rail 2063 sliding inside. The slide rail 2063 and the guide rail 2061 are designed with a dovetail so that the slide rail 2063 is embedded in the guide rail 2061, so that the guide rail 2061 can be limited to prevent the slide rail 2063 from falling off. At the same time, the slide rail 2063 can slide smoothly in the guide rail 2061, so as to meet the longitudinal adjustment operation of the shovel plate structure 2062. The shovel plate structure 2062 is fixedly connected below the slide rail 2063. The right sides of the two adjustable shovel plates 206 are provided with a hydraulic longitudinal adjustment component 208, and the upper parts of the two hydraulic longitudinal adjustment components 208 are connected through two connection components 209.

[0046] A displacement assembly 202 is arranged above one of the adjustable shovel plates 206. The displacement assembly 202 includes a screw 2021 and two fixing plates 2022. The two fixing plates 2022 are fixedly connected above one of the guide rails 2061. The screw 2021 is rotatably mounted on the two fixing plates 2022 through two bearings. The fixing plates 2022 and the bearings can play a role in erecting and fixing the screw 2021, and the bearings can assist the screw 2021 in rotating, thereby reducing the resistance to the rotation of the screw 2021. A nut 2026 is threadedly connected to the screw 2021.

The slide plate 2027 slides in one of the slide grooves 204. The slide plate 2027 can slide smoothly in the slide groove 204, so that the nut 2026 maintains a stable movement. Both ends of the screw rod 2021 are fixedly connected with the threaded seat 2023. The threaded seat 2023 is threadedly connected with a fixing bolt 2024. The fixing bolt 2024 penetrates the fixing port 2025. The fixing bolt 2024 is screwed into the fixing port 2025 through the threaded transmission of the fixing bolt 2024 and the threaded seat 2023, so that the fixing bolt 2024 is screwed into the fixing port 2025, thereby locking the screw rod 2021 and improving stability. The fixing port 2025 is opened on the fixing plate 2022, and the displacement component 2 A reciprocating motion assembly 207 is connected to the lower side of the slide 2027. The reciprocating motion assembly 207 includes two support plates 2072, and the two support plates 2072 are fixedly connected to the slide 2027. A motor 2071 is installed on one side of one of the support plates 2072. The output shaft of the motor 2071 is fixedly connected to a crank 2073. The crank 2073 is rotatably mounted on the other support plate 2072 through a bearing. One end of the crank 2073 is arranged in an annular frame 2074. The notch of the annular frame 2074 can provide a movable space for the crank 2073, so that the crank 2073 can rotate smoothly. At the same time, the rotation of the crank 2073 can drive the annular frame 2074 to reciprocate. The annular frame 2074 is fixedly connected to the slide 2027. It is connected to the top of one of the sliders 2032, the bottom of the reciprocating motion component 207 is connected to one end of the telescopic component 203, and the tops of the two adjustable shovel plates 206 and the fixed shovel plate 205 are connected through the telescopic component 203. The telescopic component 203 includes a telescopic frame 2031, and the telescopic frame 2031 is hinged to one end of the two guide rails 2061 and the top of the fixed shovel plate 205. The telescopic frame 2031 is also hinged to the three sliders 2032. The slider 2032 can slide smoothly along the slide groove 204, so that the telescopic frame 2031 can stably extend and retract, so that the telescopic frame 2031 can smoothly drive the adjustable shovel plate 206 and the fixed shovel plate 205 to move smoothly, and the slider 2032 slides in the slide groove 204.

[0047] In this embodiment, the crank 2073 is driven to rotate by the motor 2071, and the crank 2073 drives the annular frame 2074 to reciprocate. The annular frame 2074 drives the telescopic frame 2031 to reciprocate through the slider 2032, so that the telescopic frame 2031 drives the adjustable shovel board 206 and the fixed shovel board 205 to realize reciprocating motion, so that the fixed shovel board 205 can preliminarily spread the soil, and then cooperate with the bulldozer 100 to advance, so that the two adjustable shovel boards 206 can perform paving operations in turn after the fixed shovel board 205, thereby effectively improving the paving uniformity, and through multi-layer paving, the soil can be spread more evenly, while improving the paving quality and efficiency.

Since the two piston rods 2082 are arranged in opposite directions, a liquid circuit can be formed between the two cylindrical tubes 2081, so that the two piston rods 2082 can move in a staggered manner, and then the two shovel plate structures 2062 can be driven to move in a staggered manner through the slide rail 2063, and the paving area can be adjusted to meet the construction needs in different situations. In addition, by increasing the paving area, the construction process can be accelerated and the construction efficiency can be improved.
