Description

Technical Field

[0001] This utility model relates to the field of paving machine technology, specifically to a base stabilization soil paver. Background Technology

[0002] Stabilized soil is an artificially produced soil that can improve the mechanical properties and stability of soil by changing its structure and composition. The application of stabilized soil is mainly concentrated in the fields of civil engineering, roads, railways and water conservancy projects, where it can significantly improve the mechanical properties and stability of soil.

[0003] A paver with publication number CN115874509A for preventing segregation of cement-stabilized aggregate base course includes a main body and a carriage installed on the main body. The carriage consists of a loading box, an inclined plate, a transition box, a discharge nozzle, and a solenoid valve. The transition box is connected to the end of the loading box away from the main body. Regardless of whether paving is in progress, the turning mechanism, mixing mechanism, and conversion mechanism all operate in a cyclical manner. This triple interference ensures that the cement maintains a highly efficient cyclical movement, which can further improve the anti-segregation effect of the cement.

[0004] The disclosed technology equipment has a strip-shaped discharge port during paving, while its material conveying pipeline is only a single discharge nozzle. This results in uneven material output at different locations during actual paving. Furthermore, when laying multiple layers, the bonding between different layers is prone to delamination due to the long paving interval or compaction, affecting the firmness of the bonding between multiple layers. Utility Model Content

[0005] Therefore, this utility model provides a base stabilized soil paver to solve the problems in the prior art where uneven material distribution in the paver leads to uneven output and easy stratification between different layers of stabilized soil.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A base stabilized soil paver includes a connecting plate, a box body, and a rotating belt. The box body is installed at the bottom of the connecting plate, and the rotating belt is installed inside the box body. An inclined plate is rotatably connected to the outer wall of the box body away from the connecting plate, and a mixing roller is provided at the bottom of the inclined plate.

[0008] A mounting plate is fixedly connected to the bottom of the connecting plate near the box body, and a base plate is fixedly connected to the side of the mounting plate near the box body.

[0009] The rotating belt has rotating rollers at both ends inside, and the rotating rollers are rotatably connected to the top of the base plate. Multiple rotating blades are arranged around the outer wall of the rotating belt.

[0010] The outer wall of the stirring roller is surrounded by multiple spiral impellers. Both ends of the stirring roller are rotatably connected to connecting blocks. The end of the connecting block away from the stirring roller is slidably connected to the housing. One end of the stirring roller is connected to a motor.

[0011] Furthermore, the bottom end of the side wall of the box body away from the connecting plate is inclined to one side of the connecting plate, and a movable baffle is slidably connected to the bottom of the bottom plate, with the top of the movable baffle away from the connecting plate inclined to the bottom.

[0012] Furthermore, a rotating plate is rotatably connected to one bottom end of the inclined plate, and electric push rods are installed on both sides of the top of the inclined plate. The top of the electric push rods is rotatably connected to the housing, and the bottom protruding end of the electric push rods is rotatably connected to the inclined plate.

[0013] Furthermore, the bottom of the rotating belt is in contact with the top of the end of the base plate away from the mounting plate, and a drive motor is provided at one end of the connecting plate near the top of the rotating roller. The bottom power output end of the drive motor is fixed to the rotating roller.

[0014] Furthermore, an electric telescopic rod is installed on the mounting plate near the bottom of the base plate, and the inner protruding end of the electric telescopic rod is fixedly connected to the movable baffle.

[0015] Furthermore, slide rails are installed on both side walls of the box body near the stirring roller. The slide rails and connecting blocks are slidably connected to each other. The interior of the connecting block is threaded with a fixing bolt at the corresponding position of the slide rail. One end of the fixing bolt passes through the side wall of the connecting block and fits against the slide rail.

[0016] This utility model has the following advantages:

[0017] 1. The drive motor drives the rotating belt to rotate via the rotating roller, which in turn rotates the rotating blades. This causes the rotating blades to move the stabilized soil, ensuring that the stabilized soil at the bottom of the rotating blades is at the same height. Excess stabilized soil is pushed to one side, resulting in a more even distribution of stabilized soil. This allows the stabilized soil to be evenly discharged to the bottom inside the box, maintaining a uniform discharge amount at different locations when the device discharges stabilized soil to the outside. At the same time, the device can also activate the tilting plate, causing it to tilt to the bottom. This adjusts the distance between the tilting plate and the ground, pushing any stabilized soil that is too high onto the bottom of the tilting plate. This height adjustment control allows the stabilized soil to move to areas that are too low, further maintaining a uniform distribution of stabilized soil.

[0018] 2. Adjusting the sliding connecting block adjusts the height of the mixing roller, allowing it to contact the bottom stabilized soil. Rotating the fixing bolt secures the connecting block, driving the mixing roller to rotate, which in turn drives the spiral impeller. This mixes the newly laid stabilized soil with the bottom soil, effectively preventing soil stratification and ensuring a more uniform distribution of the stabilized soil. After mixing, the height of the stabilized soil can be adjusted by adjusting the bottom of the inclined plate. The contact between the rotating plate and the surface of the stabilized soil ensures that the soil maintains the required height after mixing and compaction, facilitating subsequent compaction.

Detailed Implementation

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] refer to Figure 1-5 The illustrated base stabilized soil paver includes a connecting plate 1, a housing 2, and a rotating belt 3. The housing 2 is installed at the bottom of the connecting plate 1, and the rotating belt 3 is installed inside the housing 2. An inclined plate 4 is rotatably connected to the outer wall of the housing 2 away from the connecting plate 1, and a mixing roller 5 is provided at the bottom of the inclined plate 4. An mounting plate 101 is fixedly connected to the bottom of the connecting plate 1 near the housing 2, and a base plate 102 is fixedly connected to the mounting plate 101 near the housing 2. Rotating rollers 302 are provided at both ends inside the rotating belt 3, and the rotating rollers 302 are rotatably connected to the top of the base plate 102. Multiple rotating blades 301 are arranged around the outer wall of the rotating belt 3. Multiple spiral impellers 501 are arranged around the outer wall of the mixing roller 5. Connecting blocks 502 are rotatably connected to both ends of the mixing roller 5. The end of the connecting block 502 away from the mixing roller 5 is slidably connected to the housing 2. A motor is connected to one end of the mixing roller 5.

[0029] like Figure 3 , Figure 4 As shown, the bottom end of the side wall of the box body 2 away from the connecting plate 1 is inclined towards one side of the connecting plate 1. A movable baffle 201 is slidably connected to the bottom of the bottom plate 102. The top of the movable baffle 201 away from the connecting plate 1 is inclined towards the bottom. An electric telescopic rod 202 is installed on the mounting plate 101 near the bottom of the bottom plate 102. The inner protruding end of the electric telescopic rod 202 is fixedly connected to the movable baffle 201, which transports the corresponding material into the inside of the box body 2, so that the material can fall to the bottom through the gap between the bottom side of the box body 2 and the bottom plate 102. At the same time, the electric telescopic rod 202 can be activated, so that the movable baffle 201 moves closer to the bottom side of the box body 2, thereby adjusting the size of the gap between the bottom of the box body 2 and one end of the bottom plate 102, and thus adjusting the falling and discharge speed of the stabilized soil.

[0030] like Figure 2 , Figure 3 As shown, a rotating plate 401 is rotatably connected to one bottom end of the inclined plate 4. Electric push rods 402 are installed on the top of the inclined plate 4 near both sides. The top of the electric push rods 402 is rotatably connected to the housing 2, and the bottom protruding end of the electric push rods 402 is rotatably connected to the inclined plate 4. When the device moves, the inclined plate 4 can be activated, causing the inclined plate 4 to tilt to the bottom, thereby adjusting the distance between the inclined plate 4 and the ground. As a result, the stabilized soil that is too high will be pushed by the bottom of the inclined plate 4, realizing the adjustment and control of the height, so that the stabilized soil moves to the position where the height is insufficient, and further maintaining the uniform distribution of the stabilized soil.

[0031] like Figure 2 , Figure 5 As shown, the bottom of the rotating belt 3 is in contact with the top of the end of the base plate 102 away from the mounting plate 101. A drive motor 303 is provided at one end of the connecting plate 1 near the top of the rotating roller 302. The power output end of the drive motor 303 is fixed to the rotating roller 302. When the drive motor 303 is started, it drives the rotating belt 3 to rotate through the rotating roller 302, which in turn causes the rotating blade 301 to rotate. This causes the rotating blade 301 to move the stabilized soil and distribute it evenly inside the box 2, making the height of the stabilized soil at the bottom of the rotating blade 301 the same. This pushes the excess stabilized soil to one side, making the stabilized soil evenly distributed, thus allowing the stabilized soil to be evenly discharged to the bottom inside the box 2.

[0032] like Figure 2 , Figure 3 As shown, slide rails 503 are installed on both sides of the box 2 near the mixing roller 5. The slide rails 503 and the connecting blocks 502 are slidably connected to each other. The connecting blocks 502 are threaded with fixing bolts 504 at the corresponding positions of the slide rails 503. One end of the fixing bolts 504 passes through the side wall of the connecting blocks 502 and fits against the slide rails 503. Adjusting the sliding connecting blocks 502 will drive the height adjustment of the mixing roller 5, so that the spiral impeller 501 on the outer wall of the mixing roller 5 can contact the bottom stabilized soil. Then, rotating the fixing bolts 504 will fix the connecting blocks 502, which can drive the mixing roller 5 to rotate, thereby driving the spiral impeller 501 to rotate. This will mix the newly laid stabilized soil with the bottom soil, effectively avoiding the separation between the soil and the stabilized soil, and also making the distribution of the stabilized soil more uniform.

[0033] Working Principle: During use, the corresponding materials can be conveniently conveyed into the interior of the box 2, allowing them to fall to the bottom through the gap between the bottom side of the box 2 and the bottom plate 102. Simultaneously, the electric telescopic rod 202 can be activated, causing the moving baffle 201 to move closer to the bottom of the box 2, thus adjusting the gap between the bottom of the box 2 and one end of the bottom plate 102, thereby regulating the falling and discharge speed of the stabilized soil. When the stabilized soil accumulates inside the box 2, the drive motor 303 can be activated, causing the drive motor 303 to drive the rotating belt 3 to rotate via the rotating roller 302, which in turn causes the rotating blades 301 to rotate, thus causing the rotating blades 301 to... The stabilized soil is moved and evenly distributed inside the housing 2, so that the height of the stabilized soil at the bottom of the rotating blade 301 is the same. Excess stabilized soil is pushed to one side, making the stabilized soil evenly distributed. This allows the stabilized soil to be evenly discharged to the bottom inside the housing 2, thus maintaining a uniform discharge amount at different positions when the device discharges stabilized soil to the outside. At the same time, when the device moves, the tilting plate 4 can also be activated, causing the tilting plate 4 to tilt to the bottom, thereby adjusting the distance between the tilting plate 4 and the ground. Stabilized soil that is too high will be pushed by the bottom of the tilting plate 4, realizing height adjustment and control, and moving the stabilized soil to the position where the height is insufficient, further maintaining the even distribution of stabilized soil.

[0034] During use, the stabilized soil falls from the bottom of the box 2, and the sliding connecting block 502 can be adjusted according to the laying height, which in turn drives the height adjustment of the mixing roller 5. This allows the spiral impeller 501 on the outer wall of the mixing roller 5 to come into contact with the bottom stabilized soil. Then, the fixing bolt 504 is rotated to fix the connecting block 502, which drives the mixing roller 5 to rotate, thereby driving the spiral impeller 501 to rotate. This mixes the newly laid stabilized soil with the bottom soil, effectively preventing the separation between the soil and the stabilized soil, and making the distribution of the stabilized soil more uniform. After mixing, the height of the stabilized soil can be adjusted by the height of the bottom of the inclined plate 4. The contact between the rotating plate 401 and the surface of the stabilized soil ensures that the stabilized soil maintains the required height after mixing and compression, which is convenient for subsequent compaction operations.

[0035] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
