AI Technical Summary
In existing technologies, excessively thick spiral blades can lead to an excessively large contact area with the mixture, increasing the risk of segregation and energy consumption. Conversely, excessively thin blades reduce wear resistance. Furthermore, if compaction is not followed closely after paving, the temperature of the mixture will drop, affecting the uniform compaction effect and construction efficiency.
The design employs spiral blades and spiral blocks that gradually thin outwards. Combined with multiple sets of initial compaction mechanisms on the rear distribution baffle and multiple sets of material blocking mechanisms on the front distribution baffle, the paving thickness is adjusted by filling gaps with spiral blocks, initial compaction, and material blocking mechanisms, ensuring uniform mixing and conveying of the mixture.
It effectively reduces the contact area between the spiral blades and the mixture, lowers the risk of segregation and energy consumption, ensures that the temperature of the mixture does not drop, and improves the uniform compaction effect and construction efficiency.

Abstract
Description
Technical Field
[0001] A paver with an improved slewing mechanism is used for road paving and belongs to the field of paver technology. Background Technology
[0002] During road construction, the mixture should be laid evenly across the required width according to the specified loose thickness. Cement-stabilized crushed stone base courses should be laid using asphalt concrete pavers or dedicated stabilized soil pavers. The pavers should have the performance characteristics of automatic leveling, full-width paving, large paving thickness, automatic control of operating speed and material supply speed, and high pre-compaction density.
[0003] The moisture content of the mixture during paving should be 0.5% to 1.0% higher than the optimum moisture content to compensate for moisture loss during paving and compaction.
[0004] The auger distributor is one of the core components of a paver. It uses the rotation of the auger blades to laterally transport the mixture from the central trough to the paving width direction, achieving a uniform distribution of the mixture. Specifically, the auger blades rotate under the drive of the drive unit, propelling the mixture axially (in the paving width direction).
[0005] However, the existing helical blades have the following technical problems:
[0006] 1. If the spiral blades are too thick, the contact area with the mixture will be too large, which will increase the risk of segregation and increase energy consumption. If the blades are too thin, the wear resistance will be reduced.
[0007] 2. If the mixture is compacted with a road roller after paving, and compaction is not followed immediately after paving, the temperature of the mixture may drop, which will affect the uniform compaction effect and reduce construction efficiency.
[0008] 3. The bottom of the front analysis baffle in the spiral distributor cannot effectively block the material sliding during the spiral blade conveying process, which can easily cause the paving thickness to not reach the required level quickly. Utility Model Content
[0009] The purpose of this invention is to provide a paver with an improved slewing mechanism, which solves the problems in the prior art where the auger blades are too thick, which easily leads to an excessively large contact area with the mixture, increasing the risk of segregation and energy consumption, and the blades are too thin, which easily leads to reduced wear resistance.
[0010] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0011] A paver with an improved slewing mechanism includes a vehicle body, a support frame mounted on the vehicle body, and a auger distributor mounted on the support frame. The auger distributor includes a front distribution baffle and a rear distribution baffle mounted on the support frame, and an auger mechanism mounted on the front distribution baffle and the vehicle body. The auger mechanism includes a drive mechanism and an auger assembly. The auger assembly includes an auger shaft driven to rotate by the drive mechanism, auger blades mounted on the auger shaft, and auger blocks mounted on the auger shaft between the auger blades. The thickness of the auger blades and auger blocks gradually decreases from the inside to the outside.
[0012] Furthermore, on the opposite side of the front distribution baffle, there are multiple sets of initial pressing mechanisms on the rear distribution baffle.
[0013] Furthermore, the initial pressing mechanism includes two mounting blocks A welded to the rear distribution baffle, and rotating holes A disposed opposite to each other on the two mounting blocks A. A roller A, with its bottom lower than the rear distribution baffle, is rotatably mounted on the rotating holes A; or
[0014] The initial pressure mechanism includes two L-shaped mounting blocks A that are threadedly fixed on the rear distribution baffle, a through hole A on the vertical plate of the two L-shaped mounting blocks A, a rotating hole B that is oppositely set on the two L-shaped mounting blocks A, and a roller B with its bottom lower than the rear distribution baffle is rotatably mounted on the rotating hole B.
[0015] Along the height direction of the rear material distribution baffle, the rear material distribution baffle is provided with multiple threaded holes A corresponding to the through holes A, and bolts A that mate with the through holes A and the threaded holes A.
[0016] Furthermore, on the opposite side of the rear material distribution baffle, the front material distribution baffle is provided with multiple sets of material blocking mechanisms.
[0017] Furthermore, the material blocking mechanism includes two mounting blocks B welded to the front material distribution baffle, a rotating shaft A fixedly mounted on the two mounting blocks B or rotatably mounted on the two mounting blocks B, an inverted T-shaped baffle A rotatably mounted on the rotating shaft A or fixedly mounted on the rotating shaft A, and a torsion spring A sleeved on the rotating shaft A between the mounting blocks B and the inverted T-shaped baffle A and connected to the mounting blocks B and the inverted T-shaped baffle A; or
[0018] The material blocking mechanism includes two L-shaped mounting blocks B threadedly fixed to the front material distribution baffle, a through hole B on the vertical plate of the two L-shaped mounting blocks B, a rotating shaft B fixedly mounted on the horizontal plate of the L-shaped mounting blocks B or rotatably mounted on the L-shaped mounting blocks B, an inverted T-shaped baffle B rotatably mounted on the rotating shaft B or fixedly mounted on the rotating shaft B, and a torsion spring B sleeved on the rotating shaft B between the L-shaped mounting blocks B and the inverted T-shaped baffle B and connected to the L-shaped mounting blocks B and the inverted T-shaped baffle B;
[0019] Along the height direction of the front material distribution baffle, the front material distribution baffle is provided with multiple threaded holes B corresponding to the through holes B, and bolts B that mate with the through holes B and the threaded holes B.
[0020] Furthermore, along the length direction of the inverted T-shaped baffle A and the inverted T-shaped baffle B, multiple baffles A and B are respectively provided at intervals on the inverted T-shaped baffle A and the inverted T-shaped baffle B.
[0021] Furthermore, the horizontal plates of the inverted T-shaped baffles A and B corresponding to torsion springs A and B are inclined surfaces that tilt towards one end.
[0022] Compared with the prior art, the advantages of this utility model are:
[0023] I. The threaded assembly in this utility model can not only convey and stir the mixture through the spiral blades and spiral blocks, but also effectively fill the gap between the spiral blades through the spiral blocks, reducing the reverse sliding of the mixture. The spiral blades and spiral blocks gradually become thinner from one side of the spiral shaft outward, which can effectively avoid the spiral blades being too thick, which can easily cause an excessive contact area with the mixture, increasing the risk of segregation and increasing energy consumption. If the thickness is too thin, it can easily cause the problem of reduced wear resistance. That is, the thin end can be effectively inserted into the mixture, further playing the role of uniform stirring and conveying.
[0024] II. This utility model, by setting multiple sets of initial compaction mechanisms on the rear distribution baffle, facilitates the initial compaction of the paved mixture by rotating the roller A on the mounting block A or the roller B on the L-shaped mounting block A after the auger blades and auger blocks have mixed and transversely conveyed the mixture. This ensures that the compaction is carried out immediately after paving, effectively preventing the temperature of the mixture from dropping and affecting the uniform compaction effect. It also improves construction efficiency. Furthermore, when the multiple sets of initial compaction mechanisms are engaged with the threaded fixing of the rear distribution baffle, it is also convenient to adjust the through hole A and the threaded hole A of different heights to adjust the initial compaction thickness of the roller B.
[0025] Third, this utility model, by setting multiple sets of material blocking mechanisms on the front distribution baffle, facilitates the resetting action of the inverted T-shaped baffle A or B applied by the torsion spring A or torsion spring B in the multiple sets of material blocking mechanisms when the spiral blades and spiral blocks are mixing and transversely conveying the mixture. This allows the mixture to act on the side of the paving thickness (i.e., the side of the mixture at the front end), effectively preventing a large amount of the mixture from sliding forward and making it difficult to quickly reach the paving thickness. At the same time, by setting torsion spring A or torsion spring B, the inverted T-shaped baffle A or inverted T-shaped baffle B can be rotated when its forward movement is obstructed, avoiding damage from force. Furthermore, when the multiple sets of material blocking mechanisms are threadedly fixed to the front distribution baffle, it is also convenient to adjust the through hole B and the threaded hole B of different heights, so as to adjust the material blocking height of the inverted T-shaped baffle A or inverted T-shaped baffle B according to the paving thickness.
[0026] IV. This utility model has multiple baffles A and B spaced apart on the inverted T-shaped baffle A and inverted T-shaped baffle B, which is beneficial for observing the paving of the mixture and avoids excessive weight of the equipment.
[0027] 5. The horizontal plates of the inverted T-shaped baffles A and B corresponding to torsion springs A and B in this utility model are inclined surfaces that tilt towards one end. The purpose is to prevent material from accumulating at the position of torsion spring A or torsion spring B, thereby increasing its rotational resistance. Attached Figure Description

[0047] Example 1
[0048] To address the problems in existing technologies, such as excessively thick spiral blades leading to an excessively large contact area with the mixture, increasing the risk of segregation and energy consumption, and excessively thin blades resulting in reduced wear resistance, the following solutions are needed. Figures 1-10 As shown, a paver with an improved slewing mechanism is provided, including a vehicle body, a support frame 1 mounted on the vehicle body, and a auger distributor 2 mounted on the support frame. The auger distributor 2 includes a front distribution baffle 3 and a rear distribution baffle 4 mounted on the support frame 1, and an auger mechanism mounted on the front distribution baffle 3 and the vehicle body. The auger mechanism includes a drive mechanism 9 and an auger assembly 5. The auger assembly 5 includes an auger shaft 6 driven to rotate by the drive mechanism 9, auger blades 7 mounted on the auger shaft 6, and auger blocks 8 mounted on the auger shaft 6 between the auger blades 7. The thickness of the auger blades 7 and the auger blocks 8 gradually decreases from the inside to the outside, that is, from one side of the auger shaft 6 to the outside. The specific thickness is selected according to actual needs. The vehicle body, support frame, drive mechanism, etc. are existing and are not described in detail here.
[0049] In practice, during paver operation, the mixture enters from the hopper between the front distribution baffle 3 and the rear distribution baffle 4. The drive mechanism rotates the auger shaft 6, which in turn rotates the auger blades 7 and auger blocks 8, thus mixing the mixture and conveying it laterally to both ends. The threaded assembly, through the auger blades and auger blocks, not only conveys and mixes the mixture but also effectively fills the gaps between the auger blades, reducing reverse slippage of the mixture. The auger blades and auger blocks gradually thin outwards from one side of the auger shaft, effectively avoiding excessively thick auger blades that could lead to an excessively large contact area with the mixture, increasing the risk of segregation and energy consumption, or excessively thin blades that could reduce wear resistance. The thinner ends effectively insert into the mixture, further promoting uniform mixing and conveying.
[0050] Example 2
[0051] Based on Embodiment 1, multiple sets of initial pressing mechanisms 10 are located on the rear material distribution baffle 4 on the opposite side of the front material distribution baffle 3. The initial pressing mechanism 10 includes two mounting blocks A11 welded to the rear material distribution baffle 4, and rotating holes A12 oppositely arranged on the two mounting blocks A11. Rollers A13 with bottoms lower than the rear material distribution baffle 4 are rotatably arranged on the rotating holes A12.
[0052] In practice, after the auger blades and auger blocks mix and transversely convey the mixture, the forward movement of the paver drives the roller A on the mounting block A to rotate and perform initial compaction on the paved mixture. This ensures that the compaction follows closely after paving, effectively preventing the temperature of the mixture from dropping and thus affecting the uniform compaction effect, while also improving construction efficiency.
[0053] or
[0054] The initial pressing mechanism 10 includes two L-shaped mounting blocks A14 threadedly fixed on the rear material distribution baffle 4, a through hole A15 on the vertical plate of the two L-shaped mounting blocks A14, a rotating hole B16 oppositely disposed on the two L-shaped mounting blocks A14, and a roller B17 with its bottom lower than the rear material distribution baffle rotatably disposed on the rotating hole B16.
[0055] Along the height direction of the rear material distribution baffle 4, the rear material distribution baffle 4 is provided with multiple threaded holes A18 corresponding to the through holes A15, and bolts A19 that cooperate with the through holes A15 and the threaded holes A18.
[0056] In practice, based on the required initial compaction thickness, the through hole A15 is matched with threaded holes A18 of different heights and fixed with bolts A. This allows the auger blades and auger blocks to mix and laterally convey the mixture, and then, through the forward movement of the paver, drive the rollers B on the L-shaped mounting block A to rotate and initially compact the paved mixture. This ensures that the subsequent rolling compaction follows closely, effectively preventing the temperature of the mixture from dropping and affecting the uniform compaction effect. It also improves construction efficiency. Furthermore, when multiple sets of initial compaction mechanisms are matched with the threaded fixing of the rear distribution baffle, it is also convenient to adjust the matching of the through hole A with threaded holes A of different heights to adjust the initial compaction thickness of the rollers B.
[0057] Example 3
[0058] Based on Embodiment 2, on the opposite side of the rear material distribution baffle 4, the front material distribution baffle 3 is provided with multiple sets of material blocking mechanisms 20. The material blocking mechanism 20 includes two mounting blocks B21 welded to the front material distribution baffle 3, a rotating shaft A22 fixedly mounted on the two mounting blocks B21 or rotatably mounted on the two mounting blocks B21, an inverted T-shaped baffle A23 rotatably mounted on the rotating shaft A22 or fixedly mounted on the rotating shaft A22, and a torsion spring A24 sleeved on the rotating shaft A22 between the mounting blocks B21 and the inverted T-shaped baffle A23 and connected to the mounting blocks B21 and the inverted T-shaped baffle A23;
[0059] In practice, by setting multiple sets of material blocking mechanisms on the front material distribution baffle, when the auger blades and auger blocks are mixing and conveying the mixture laterally, the torsion spring A in the multiple sets of material blocking mechanisms applies a reset action to the inverted T-shaped baffle A, causing it to act on the side of the mixture of the paving thickness (i.e., the side of the mixture at the front end), which effectively prevents a large amount of the mixture from sliding forward and making it difficult to quickly reach the paving thickness. At the same time, by setting torsion spring A, it is possible to make the inverted T-shaped baffle A rotate along the rotation axis A or along the mounting block B when its forward movement is blocked, thus avoiding damage from stress.
[0060] or
[0061] The material blocking mechanism 20 includes two L-shaped mounting blocks B25 threadedly fixed on the front material distribution baffle 3, through holes B26 on the vertical plates of the two L-shaped mounting blocks B25, a rotating shaft B27 fixedly mounted on the horizontal plate of the L-shaped mounting block B25 or rotatably mounted on the L-shaped mounting block B25, an inverted T-shaped baffle B28 rotatably mounted on the rotating shaft B27 or fixedly mounted on the rotating shaft B27, and a torsion spring B29 sleeved on the rotating shaft B27 between the L-shaped mounting block B25 and the inverted T-shaped baffle B28 and connected to the L-shaped mounting block B25 and the inverted T-shaped baffle B28.
[0062] Along the height direction of the front material distribution baffle 3, the front material distribution baffle 3 is provided with multiple threaded holes B30 corresponding to the through holes B26, and bolts B31 that cooperate with the through holes B26 and the threaded holes B30.
[0063] In practice, based on the required thickness of the mixture to be paved, the through hole B26 is matched with threaded holes B30 of different heights and fixed with bolts B31. This facilitates the lateral conveying of the mixture by the auger blades and auger blocks. The torsion springs B in the multiple material-blocking mechanisms apply a resetting action to the inverted T-shaped baffle B, causing it to act on the side of the mixture at the paving thickness (i.e., the side of the mixture at the front end). This effectively prevents a large amount of mixture from sliding forward, making it difficult to quickly reach the paving thickness. Simultaneously, the torsion springs B allow the inverted T-shaped baffle B to rotate along the rotation axis B or along the L-shaped mounting block B25 when its forward movement is obstructed, preventing damage from stress. Furthermore, when the multiple material-blocking mechanisms are threadedly fixed to the front distribution baffle, it also facilitates adjusting the matching of the through hole B with threaded holes B of different heights, allowing for adjustment of the material-blocking height of the inverted T-shaped baffle A or B according to the paving thickness.
[0064] Example 4
[0065] Based on Example 3, multiple baffles A32 and B33 are respectively spaced apart on the inverted T-shaped baffles A23 and B28 along their length direction. Multiple baffles A and B are also spaced apart on the inverted T-shaped baffles A and B. This is to facilitate the observation of the paving of the mixture and to avoid problems such as excessive equipment weight caused by making all the inverted T-shaped baffles A23 and B28 into blocks to meet the blocking requirements.
[0066] Example 5
[0067] Based on Example 4, the horizontal plates of the inverted T-shaped baffles A23 and B28 corresponding to torsion springs A24 and B29 are inclined surfaces that tilt towards one end. One end is the lower end, and the tilt angle is set according to actual needs. The purpose is to prevent material from accumulating at the position of torsion spring A or torsion spring B, thereby increasing its rotational resistance.
