Abstract
Description
Technical Field
[0001] This application relates to the field of paver technology, specifically to a paver auger device and a paver. Background Technology
[0002] During asphalt paving, especially water-stabilized paving, significant vertical segregation often occurs within the auger: larger particles move outward due to centrifugal force as the auger blades rotate, while simultaneously rolling downwards due to gravity and other forces in the gaps between the blades and the front and rear baffles. This results in a higher proportion of coarse aggregate on the surface or bottom of the paved layer, and a lower proportion in the middle, thus creating noticeable vertical segregation. Similar situations exist to varying degrees in asphalt surface layer paving. Severe vertical segregation often leads to insufficient strength at the bottom of the water-stabilized layer, making core sampling impossible, or large pores on the asphalt surface that allow water seepage. After the road is opened to traffic, this often induces early pavement damage.
[0003] Currently, there are two main methods to prevent vertical segregation in pavers. One is to change the shape and pitch of the auger blades to ensure they are embedded in the mix, thus reducing the impact of centrifugal force. The other is to add rubber vertical baffles, material-blocking chains, or flexible curtains to the front baffle. However, the use of different blade sizes is complex in terms of design and installation, and the centrifugal force remains, limiting their effectiveness. Rubber and chain vertical baffles cannot effectively prevent vertical segregation caused by larger particles falling to the bottom under gravity; they only prevent material from overflowing the front baffle. Enclosed or excessively long flexible curtains and chains are easily caught in the mix, causing interference from other forces. Furthermore, these devices cannot effectively prevent the coarse aggregate at the top two right-angled sections of the paver from accumulating into low-flowability, "stagnant" material, still resulting in surface vertical segregation. Summary of the Invention
[0004] The embodiments of this application are intended to at least improve one of the technical problems existing in the prior art or related art.
[0005] In view of this, one object of the embodiments of this application is to provide a paver auger device.
[0006] Another object of embodiments of this application is to provide a paver.
[0007] To achieve the above objectives, a paver auger device is provided according to the first aspect of this application, comprising: a spiral fabric distribution structure; a front baffle disposed on one side of the spiral fabric distribution structure; a non-flexible movable component rotatably disposed at the bottom of the front baffle; a front baffle chamfer disposed at the top of the front baffle and located on the side of the front baffle close to the spiral fabric distribution structure; a rear baffle disposed on the side of the spiral fabric distribution structure away from the front baffle; and a rear baffle chamfer disposed opposite to the front baffle chamfer and connected to the side of the rear baffle close to the spiral fabric distribution structure; wherein the front baffle chamfer, the front baffle, the non-flexible movable component, the rear baffle, and the rear baffle chamfer enclose a non-closed fabric distribution cavity, and the spiral fabric distribution structure is located within the non-closed fabric distribution cavity.
[0008] The paver auger device provided in this application includes a spiral material distribution structure, a front baffle, a non-flexible movable component, a front baffle chamfer, a rear baffle, and a rear baffle chamfer. The non-flexible movable component is rotatably mounted at the bottom of the front baffle, allowing for manual angle adjustment. This improves adaptability to preventing vertical segregation during paving of mixtures with different blade sizes, vertical heights, and particle sizes. It can be adjusted and configured according to different construction scenarios without interfering with the material distribution operation of the blades. The front baffle chamfer, the front baffle, the non-flexible movable component, the rear baffle, and the rear baffle chamfer together enclose a non-enclosed material distribution cavity. The spiral material distribution structure is located within this cavity, preventing the possibility of enclosed soft material curtains getting caught in the mixture and interfering with its distribution. Simultaneously, it releases stress at appropriate locations, avoiding stress interference on the front baffle. A front baffle chamfer is located at the top of the front baffle, and a rear baffle chamfer is located at the top of the rear baffle, effectively reducing dead material at right angles.
[0009] Specifically, in the paving of large-particle-size water-stabilized or asphalt pavements, during the auger placement process of the paver, the coarse aggregate in the mixture encounters the chamfers of the front and rear baffles at the top and returns to the area affected by the auger blades' agitation, blending into the mixture. At the bottom, near the non-flexible moving component, it is supported by the non-flexible moving component and does not roll downwards, continuing to flow within the agitation range of the blades. The aggregate falls and is released at a relatively low distance from the ground at the tail of the non-flexible moving component, at which point there is essentially no vertical segregation.
[0010] In addition, the technical solution provided in this application may also have the following additional technical features:
[0011] In some technical solutions, the paver auger device may optionally include: a stop bar located at the bottom of the rear baffle, the stop bar protruding towards the side closer to the non-enclosed concrete distribution chamber, and the side of the stop bar away from the non-enclosed concrete distribution chamber being flush with the rear baffle.
[0012] In this technical solution, the paver auger device also includes a stop bar. The stop bar is located at the bottom of the rear baffle, protruding towards the side closest to the non-enclosed material distribution chamber. This effectively reduces the lateral force and bending moment on the bottom edge of the rear baffle, minimizing the possibility of affecting the vibratory beam and improving the compaction of the feed material. The side of the stop bar facing away from the non-enclosed material distribution chamber is flush with the rear baffle, reducing interference and ensuring it does not affect the placement of components such as the vibratory beam. Specifically, the stop bar is a small semi-circular bar structure on the right. When the mixture encounters the rear baffle, influenced by the stop bar, some of the mixture rises back into the blade agitation range, while some downwards is distributed into the pavement thickness. Simultaneously, the stop bar provides a certain feed angle, aiding in the vibration of the vibratory beam and the action of the screed. The stop bar's decomposition of the horizontal force on the mixture effectively reduces the horizontal force and bending moment at this location, significantly mitigating the possibility of long-term stress and deformation at this end affecting the operation of the vibratory beam or even causing it to stall. By incorporating chamfered front baffles, non-flexible movable components, chamfered rear baffles, and stop bars, the mixture, especially coarse aggregate, can be effectively kept within the effective agitation range of the auger blades throughout the entire material distribution process, improving the flowability of the coarse aggregate. This significantly reduces vertical segregation and, to some extent, increases the initial compaction degree. It also effectively ensures the working efficiency of the vibratory beam and extends its service life.
[0013] In some technical solutions, the non-flexible moving component may optionally include a guide part, a connecting part, and a rotating part. The rotating part is rotatably disposed at the bottom of the front baffle via a rotating shaft. The connecting part, the rotating part, and the guide part are connected in sequence. The rotating part has a circular structure, and the rotating shaft is located at the center of the rotating part.
[0014] In this technical solution, the non-flexible moving component includes a guiding part, a connecting part, and a rotating part. The rotating part is rotatably mounted on the bottom of the front baffle via a rotating shaft, and the connecting part, rotating part, and guiding part are connected in sequence. The connecting part, rotating part, and guiding part can be integrally formed or welded together.
[0015] In some technical solutions, optionally, the guide section extends into the non-enclosed fabric cavity, the cross-section of the guide section is an S-shaped arc surface, and the end of the guide section away from the rotating part is provided with a rounded chamfer.
[0016] In this technical solution, the material guide extends out in an S-shaped arc, and its end is also rounded with a chamfer. The overall design of the non-flexible moving component maintains a smooth and linear shape from the front baffle to the end.
[0017] In some technical solutions, optionally, the radius of curvature of the S-shaped arc surface is 300mm-450mm, and the rotating part is a cylinder with a diameter of 80mm-140mm.
[0018] In this technical solution, the radius of curvature of the S-shaped arc surface is 300mm-450mm, extending 150mm-250mm into the non-enclosed fabric cavity. The rotating part is a cylinder with a diameter of 80mm-140mm, which can maintain the transition angle between the component and the front baffle unchanged during rotation.
[0019] In some technical solutions, the paver auger device may optionally include an adjustment device connected to the connecting part for adjusting the rotation angle of the non-flexible moving component.
[0020] In this technical solution, the paver auger device also includes an adjustment device for adjusting the rotation angle of the non-flexible moving component. Specifically, the adjustment device is connected to the connection part of the non-flexible moving component, and the rotation angle of the non-flexible moving component is adjusted by changing the position of the connection part.
[0021] In some technical solutions, the adjusting device may optionally include: a screw connected to the front baffle, the screw being inserted into the connecting part, the connecting part being slidable relative to the screw; a spring sleeved on the screw, the two ends of the spring abutting against the connecting part and the front baffle respectively; and an adjusting nut threadedly connected to the screw and located on the side of the connecting part away from the spring.
[0022] In this technical solution, the adjusting device includes an adjusting nut, a screw, and a spring. The screw is welded to the outside of the front baffle, and a connecting part of the screw, which is a non-flexible moving component, is inserted through the screw. The connecting part can slide relative to the screw. The spring is sleeved on the screw, with its two ends abutting against the connecting part and the front baffle, respectively. The adjusting nut is located on the side of the connecting part facing away from the spring and is threadedly connected to the screw. By rotating the adjusting nut in both directions, the connecting part can be moved axially along the screw. The adjusting device can adjust the component to adapt to fabric blades of different radii, forming a semi-enclosed cavity that is nearly concentric, ensuring consistent flow space, reducing resistance to the flow of the mixture, and improving the smoothness within the cavity. Adjustment is achieved through the adjusting nut, screw, and spring, making installation simple and reliable. The spring keeps the component in a state of force balance and has a certain range of elastic movement. The adjusting nut limits the counterclockwise rotation range of the component. When the amount of mixture in the fabric cavity increases and the pressure increases, the component moves clockwise as a whole, increasing the space of the fabric cavity and accelerating pressure release to reduce spatial flow resistance, while simultaneously compressing the spring until it reaches its limit. As the amount of mixed material in the fabric cavity decreases, the pressure decreases. Under the rebound action of the spring, the entire component moves counterclockwise, reducing the space of the fabric cavity to ensure that the mixed material is as close as possible to the fabric blades and improve its fluidity.
[0023] In some technical solutions, optionally, the auger structure includes: auger blades; a spreader boom connected to the auger blades; and / or the paver auger device also includes: a vibrating beam connected to the rear baffle; and a screed connected to the rear baffle.
[0024] In this technical solution, the auger structure includes auger blades and a distributor rod, with the distributor rod connected to the auger blades. The paver auger also includes a vibrating beam and a screed. The vibrating beam is connected to the rear baffle. The screed is connected to the rear baffle.
[0025] In some technical solutions, optionally, there are multiple non-flexible movable components, which are detachably connected to the front baffle; and / or the front baffle has a right-angle chamfer with an inner radius of 250mm-350mm and extends 120mm-200mm into the non-enclosed fabric cavity; and / or the rear baffle has a right-angle chamfer with an inner radius of 250mm-350mm and extends 120mm-200mm into the non-enclosed fabric cavity.
[0026] In this technical solution, there are multiple non-flexible movable components, which are detachably connected to the front baffle. It can be understood that these multiple non-flexible movable components can be manufactured in sections, allowing for flexible installation, removal, and replacement. Specifically, through an adjustment device, different adjustment ranges can be set in different sections of the front baffle, allowing the operator to make differentiated adjustments based on the actual paving conditions. During specific adjustments, the material level height across the cross-section of the screed during actual paver construction can be considered. Generally, for the front baffle furthest from the paver body, a higher adjustment range (reducing the material cavity) helps maintain the embedment depth of the material blades across the entire cross-section of the material cavity and the material head height in front of the screed. The consistency and stability of the material head height in front of the screed is one of the core factors ensuring the overall force balance of the screed. Therefore, the differentiated adjustment of the non-flexible movable components ultimately contributes to the overall smooth operation of the paver and the improvement of paving quality. The front baffle and rear baffle have right-angle chamfers, effectively reducing the phenomenon of dead material at right-angle locations. The inner radius of the right-angle chamfer of the front and rear baffles is 250mm-350mm, which can adapt to the spatial size design of the "material trough" of the spiral concrete pack of various pavers and the size and layout of the blades. At the same time, it extends laterally into the non-enclosed concrete packing cavity by a certain length of 120mm-200mm, which improves the flowability of the "dead material" at the top of the concrete packing cavity without hindering the operator's observation of the material level in the concrete packing cavity.
[0027] According to the technical solution of the second aspect of this application, a paver is provided, including: a paver auger device as described in any of the technical solutions of the first aspect of this application.
[0028] The paver provided by this application includes the paver auger device of any of the technical solutions in the first aspect of this application, and therefore has all the beneficial effects of the paver auger device of any of the technical solutions in the first aspect of this application, which will not be repeated here.

Detailed Implementation
[0036] To better understand the above-mentioned objects, features, and advantages of the embodiments according to this application, the embodiments according to this application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the features of the embodiments according to this application can be combined with each other.
[0037] Numerous specific details are set forth in the following description in order to provide a full understanding of the embodiments according to this application. However, the embodiments according to this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection provided by the embodiments according to this application is not limited to the specific embodiments disclosed below.
[0038] The following reference Figures 1 to 4 Some embodiments provided in this application are described.
[0039] like Figure 1 and Figure 2 As shown, a paver auger device 10 according to an embodiment of this application includes an auger structure 110, a front baffle 120, a non-flexible movable member 130, a front baffle chamfer 140, a rear baffle 150, and a rear baffle chamfer 160. Specifically, the front baffle 120 is disposed on one side of the auger structure 110. The non-flexible movable member 130 is rotatably disposed at the bottom of the front baffle 120. The front baffle chamfer 140 is disposed at the top of the front baffle 120 and is located on the side of the front baffle 120 closest to the auger structure 110. The rear baffle 150 is disposed on the side of the auger structure 110 away from the front baffle 120. The rear baffle chamfer 160 is disposed opposite to the front baffle chamfer 140 and is connected to the side of the rear baffle 150 closest to the auger structure 110. Among them, the front baffle chamfer 140, the front baffle 120, the non-flexible movable component 130, the rear baffle 150, and the rear baffle chamfer 160 enclose the non-closed fabric cavity 170, and the spiral fabric structure 110 is located inside the non-closed fabric cavity 170.
[0040] The paver auger device 10 provided in this embodiment includes a spiral material distribution structure 110, a front baffle 120, a non-flexible movable component 130, a front baffle chamfer 140, a rear baffle 150, and a rear baffle chamfer 160. The non-flexible movable component 130 is rotatably mounted at the bottom of the front baffle 120, and its angle can be manually adjusted. This improves adaptability to preventing vertical segregation during the paving of mixtures with different blade sizes, vertical heights, and particle sizes. It can be adjusted and set according to different construction scenarios without interfering with the material distribution operation. The front baffle chamfer 140, front baffle 120, non-flexible movable component 130, rear baffle 150, and rear baffle chamfer 160 enclose a non-enclosed material distribution cavity 170. The spiral material distribution structure 110 is located within the non-enclosed material distribution cavity 170, which can prevent the possibility of enclosed soft material curtains rolling into the mixture and interfering with the mixture distribution. Simultaneously, it releases stress at appropriate locations to avoid stress interference on the front baffle 120. The top of the front baffle 120 is provided with a front baffle chamfer 140, and the top of the rear baffle 150 is provided with a rear baffle chamfer 160, which can effectively reduce the phenomenon of dead material at right angles.
[0041] Specifically, during the paving of large-particle-size water-stabilized or asphalt pavements, when the paver is using a 30-inch auger for material distribution, the coarse aggregate in the mixture encounters the chamfers 140° and 160° of the front and rear baffles at the top. It then returns to the area affected by the auger blades' agitation and integrates into the mixture. At the bottom, near the non-flexible movable component 130, it is supported by the component and does not roll downwards, continuing to flow within the agitation range of the blades. The aggregate is released at a lower position above the ground at the tail of the non-flexible movable component 130, at which point there is virtually no vertical segregation.
[0042] In some embodiments, the paver auger device 10 may optionally include a stop bar 180. The stop bar 180 is located at the bottom of the rear baffle 150 and protrudes towards the side near the non-enclosed material distribution chamber 170. This effectively reduces the lateral force and bending moment on the bottom edge of the rear baffle 150, reduces the possibility of affecting the vibrating beam 210, and improves the compaction of the material. Specifically, the stop bar 180 protrudes in an arc shape towards the side near the non-enclosed material distribution chamber 170, such as a default round bar structure with a small semicircle on the right side. When the mixture encounters the rear baffle 150, influenced by the stop bar 180, part of the mixture rises back into the blade agitation range, while part downwards is distributed into the paving thickness. Simultaneously, the stop bar 180 provides a certain entry angle, aiding in the vibration of the vibrating beam 210 and the action of the screed 220. Furthermore, the side of the stop bar 180 facing away from the non-enclosed spreading cavity 170 is flush with the rear baffle 150, reducing interference and ensuring it does not affect the placement of components such as the vibrating beam 210. The stop bar 180 effectively reduces the horizontal force and bending moment at this location by decomposing the horizontal force of the mixture, significantly mitigating the possibility of long-term stress deformation affecting the operation of the vibrating beam 210 or even causing it to stall. By incorporating the front baffle chamfer 140, the non-flexible movable component 130, the rear baffle chamfer 160, and the stop bar 180, it is effectively ensured that the mixture, especially coarse aggregate, remains within the effective agitation range of the auger blades throughout the paving process, improving the flowability of the coarse aggregate. This significantly reduces vertical segregation and improves initial compaction to a certain extent. It also effectively ensures the working efficiency of the vibratory beam 210 and extends its service life. In an optional embodiment, the front baffle chamfer 140 can be fixedly installed on the front baffle by welding. Similarly, the rear baffle chamfer 160 and the stop bar 180 can be fixedly installed on the rear baffle 150 by welding.
[0043] like Figure 3 As shown, in some embodiments, the non-flexible movable component 130 optionally includes a guiding part 132, a connecting part 136, and a rotating part 134. The rotating part 134 is rotatably disposed at the bottom of the front baffle 120, and the connecting part 136, the rotating part 134, and the guiding part 132 are connected in sequence. The connecting part 136, the rotating part 134, and the guiding part 132 can be integrally formed or welded together. Specifically, the rotating part 134 is rotatably connected to the front baffle 120 via a rotating shaft, and the rotating part 134 is circular in shape, i.e., the rotating part 134 has a circular structure, with the rotating shaft located at the center of the rotating part 134. This ensures that the transition angle between the rotating part 134 and the front baffle 120 remains unchanged when the non-flexible movable component 130 rotates, thus guaranteeing consistent flow space, reducing resistance to the flow of the mixture, and improving the smoothness within its cavity.
[0044] In some embodiments, the paver auger device 10 may optionally include an adjusting device 190, which is used to adjust the rotation angle of the non-flexible movable member 130. The adjusting device 190 is connected to the connecting portion 136 of the non-flexible movable member 130. By changing the position of the connecting portion 136, the rotation angle of the non-flexible movable member 130 can be adjusted. Since the transition angle between the rotating portion 134 and the front baffle 120 remains unchanged when the non-flexible movable member 130 rotates, the adjusting device 190 can adjust the member to adapt to the fabric blades of different radii, forming a semi-enclosed cavity that is close to a concentric circle, so as to ensure consistent flow space, reduce the resistance of the mixture flow, and improve the smoothness of the cavity.
[0045] In some embodiments, the adjusting device 190 optionally includes an adjusting nut 192, a screw 194, and a spring 196. The screw 194 is welded to the outside of the front baffle 120 and is inserted into the connecting portion 136, i.e., the screw 194 passes through the connecting portion 136 of the non-flexible movable member 130. The connecting portion 136 can slide relative to the screw 194. It is understood that the connecting portion 136 is provided with a through hole for the screw 194 to pass through, and the diameter of the through hole is larger than the diameter of the screw 194. The spring 196 is sleeved on the screw 194, and the two ends of the spring 196 abut against the connecting portion 136 and the front baffle 120, respectively. The adjusting nut 192 is located on the side of the connecting portion 136 facing away from the spring 196. The adjusting nut 192 is threadedly connected to the screw 194. By rotating the adjusting nut 192 in both directions, the connecting portion 136 can be moved axially along the screw 194. The non-flexible movable component 130 can be adjusted by the adjusting device 190 to adapt to fabric blades of different radii, forming a semi-enclosed cavity that is nearly concentric, ensuring consistent flow space while reducing resistance to the flow of the mixture and improving its smoothness within the cavity. Adjustment is achieved through the adjusting nut 192, screw 194, and spring 196, making installation simple and reliable. The spring 196 keeps the component in a state of force balance and provides a certain range of elastic movement. The adjusting nut 192 limits the counterclockwise rotation range of the non-flexible movable component 130. When the mixture in the non-enclosed fabric cavity 170 increases and the pressure rises, the non-flexible movable component 130 moves clockwise as a whole, increasing the space of the non-enclosed fabric cavity 170 and accelerating pressure release to reduce flow resistance. Simultaneously, this compresses the spring 196 until it reaches its limit. As the amount of mixture in the non-enclosed fabric cavity 170 decreases, the pressure decreases. Under the rebound action of the spring 196, the non-flexible movable component 130 moves counterclockwise as a whole, reducing the space of the non-enclosed fabric cavity 170 to ensure that the mixture is as close as possible to the fabric blades, thereby improving its flowability. In some embodiments, optionally, the connecting portion 136 is connected to the rotating portion 134 at the outer edge of the rotating portion 134, and the line connecting the connection point of the connecting portion 136 and the rotating portion 134 to the rotation axis is substantially perpendicular to the extension direction of the connecting portion 136, thereby amplifying the lever effect and improving the force distribution.
[0046] In some embodiments, the spiral fabric structure 110 may optionally include spiral fabric blades 112 and fabric feeder rods 114, with the fabric feeder rods 114 connected to the spiral fabric blades 112.
[0047] In some embodiments, the paver auger 10 may optionally include a vibratory beam 210 and a screed 220. The vibratory beam 210 is connected to the rear baffle 150. The screed 220 is connected to the rear baffle 150.
[0048] In some embodiments, optionally, there are multiple non-flexible movable components 130, and these multiple non-flexible movable components 130 are detachably connected to the front baffle 120. It is understood that the multiple non-flexible movable components 130 can be manufactured in sections for flexible loading, unloading, and replacement. Specifically, different adjustment ranges can be set in different sections of the front baffle 120 via the adjustment device 190, allowing the operator to make differentiated adjustments based on the actual paving situation. Specifically, the adjustment can be combined with the cross-sectional material height within the full width of the screed 220 during paver construction. Generally, the higher the adjustment range of the front baffle 120, which is farther from the paver body (reducing the size of the non-enclosed material cavity), the better it helps maintain the embedment depth of the material blades across the entire cross-section of the non-enclosed material cavity 170 and the material head height in front of the screed 220. The consistency and stability of the material head height in front of the screed 220 are one of the core factors ensuring the overall force balance of the screed 220. Therefore, the differentiated adjustment of the non-flexible movable components 130 ultimately contributes to the overall smooth operation of the paver and the improvement of paving quality.
[0049] In some embodiments, optionally, the length of each non-flexible movable member 130 and the front baffle 120 is between 0.5m and 1m. The number of adjusting devices 190 can be set to two, with the two adjusting devices 190 spaced apart on the front baffle 120 and respectively connected to the connecting part 136, thereby adjusting the rotation angle of the non-flexible movable member 130.
[0050] In some embodiments, the guide portion 132 may extend out in an S-shaped arc, with its end also having a rounded chamfer. The overall design of the non-flexible movable component 130 maintains a smooth and linear shape from the front baffle 120 to the end.
[0051] In some embodiments, the radius of curvature of the S-shaped arc surface is optionally 300mm-450mm, extending 150mm-250mm into the non-enclosed fabric cavity 170. The rotating part 134 is a cylinder with a diameter of 80mm-140mm, which can maintain the transition angle between the component and the front baffle 120 unchanged during rotation.
[0052] In some embodiments, optionally, the front baffle chamfer 140 is a right-angle chamfer, and the rear baffle chamfer 160 is also a right-angle chamfer, which can effectively reduce the phenomenon of dead material at the right angle. The inner arc radius of the right-angle chamfer of the front and rear baffles is 250mm-350mm, which can adapt to the spatial size design of the "material trough" of the auger of various pavers and the size and layout of the blades. At the same time, it extends laterally into the non-enclosed material cavity for a certain length of 120mm-200mm, which improves the flowability of "dead material" at the top of the material cavity while not hindering the operator's observation of the material level in the material cavity.
[0053] like Figure 4 As shown, a paver 30 according to an embodiment of this application includes a paver auger device 10 as described in any of the above embodiments.
[0054] The paver 30 provided according to the embodiments of this application includes the paver auger device 10 as described in any of the above embodiments, and thus has all the beneficial effects of the paver auger device 10 as described in any of the above embodiments, which will not be repeated here.
[0055] like Figure 1 and Figure 2 As shown, the paver auger device 10 according to a specific embodiment of this application has a rotating movable component that allows for manual angle adjustment, and the material is non-flexible. This improves adaptability to prevent vertical segregation when paving mixtures with different blade sizes, vertical heights, and particle sizes. It also does not interfere with the blade's material distribution. By forming a non-enclosed structure, the possibility of enclosed soft material curtains rolling into the mixture and interfering with its distribution is eliminated. Simultaneously, stress is released at appropriate locations to avoid stress interference on the front baffle 120. By designing a stop bar 180 at the bottom of the rear baffle, the lateral stress and bending moment at the bottom edge of the baffle are effectively reduced, decreasing the possibility of affecting the vibrating beam 210 and improving the compaction of the feed material. The right-angle chamfered component at the top of the baffle effectively reduces the "dead material" phenomenon at right-angle locations.
[0056] Specifically, the paver auger device 10 includes a front baffle 120, a front baffle chamfer 140, a non-flexible movable component 130, a spreader rod 114, a spiral spreader blade 112, a rear baffle chamfer 160, a rear baffle 150, a stop bar 180, a vibrating beam 210, a screed 220, an adjusting nut 192, and a screw 194.
[0057] During the paving of large-particle-size water-stabilized or asphalt pavements, when the paver is using a 30-inch auger for material distribution, the coarse aggregate in the mixture encounters the chamfers 140° on the front baffle and 160° on the rear baffle at the top. It then returns to the area affected by the auger blades' agitation and integrates into the mixture. At the bottom, near the non-flexible movable component 130, it is supported by this device and does not roll downwards, continuing to flow within the agitation range of the blades. The aggregate is released at a relatively low distance from the ground at the tail of the non-flexible movable component 130, at which point there is virtually no vertical segregation.
[0058] When the mixture encounters the rear baffle 150, influenced by the stop rod 180, part of the mixture rises back into the blade agitation range, while part downwards is distributed into the pavement thickness. Simultaneously, the stop rod 180 provides a certain feed angle, aiding in the vibration of the vibrating beam 210 and the action of the screed 220. The stop rod 180 effectively reduces the horizontal force and bending moment at this location by decomposing the horizontal force of the mixture, significantly mitigating the possibility of long-term stress deformation affecting the operation of the vibrating beam 210 or even causing it to stall. The adjusting nut 192 is fixed to the non-flexible movable component 130, and the screw 194 is fixed to the front baffle 120. Through the toothed blocks on the screw 194 and the locking holes on the adjusting nut 192, the rotation and locking of the non-flexible movable component 130 can be achieved, allowing for adjustment and adaptation according to different construction conditions.
[0059] The entire system effectively ensures that the mixture, especially the coarse aggregate, remains within the effective agitation range of the auger blades throughout the entire material placement process, improving the flowability of the coarse aggregate. This significantly reduces vertical segregation and, to some extent, increases the initial compaction degree. It also effectively ensures the working efficiency of the vibratory beam 210 and extends its service life.
[0060] In summary, the beneficial effects of the embodiments of this application are as follows:
[0061] 1. A rotating, non-flexible movable component is installed under the front baffle, allowing for manual angle adjustment. The material is non-flexible. This improves adaptability to preventing vertical segregation in mixtures with different blade sizes, vertical heights, and particle sizes, and can be adjusted and configured according to different construction scenarios. Simultaneously, it does not interfere with the material distribution operation of the auger blades. The movable component can be manufactured in sections for flexible loading, unloading, and replacement.
[0062] 2. The design of the bottom stop bar component of the rear baffle effectively reduces the horizontal force and bending moment at the bottom edge of the baffle, reducing the possibility of the vibratory beam being suffocated due to bending of the bottom of the rear baffle. At the same time, it can provide a certain feeding angle, which helps to improve the compactness of the feeding material.
