Description

Technical Field

[0001] This application relates to the technical field of road construction, and more particularly to a spiral paver and a paver machine. Background Technology

[0002] A paver is an important piece of equipment in road construction, used to spread aggregates such as asphalt, concrete or stabilized soil evenly on the roadbed to form a smooth pre-compacted layer.

[0003] There are many specifications and models of pavers, and the structures of different types of pavers are not entirely the same, but their structures generally include: frame, power system (including engine and hydraulic transmission system), walking system, electrical control system, material receiving and conveying system (including front push roller, receiving hopper, scraper conveyor, and auger distributor), leveling system, screed device, and auger paver (commonly known as the auger distribution system), etc. The auger paver is used to evenly distribute the aggregate conveyed by the material receiving and conveying system across the full width of the paver. Specifically, the auger paver spreads the aggregate by rotating the auger.

[0004] To ensure the stability of the auger, a support frame is usually installed in the middle section of the auger. This support frame connects the auger to the screeding device and supports the auger. In related technologies, aggregate segregation is prone to occur at the support frame, leading to uneven aggregate paving and affecting the paving quality. Summary of the Invention

[0005] Based on this, this application provides a spiral paver and a paver to solve the problem of uneven paving by spiral pavers in related technologies.

[0006] In a first aspect, embodiments of this application provide a spiral paver, applied to a paver, comprising:

[0007] Support components, fasteners connected to the paver;

[0008] An auger includes a rotating shaft and a material distributing spiral blade. The rotating shaft is rotatably connected to the support assembly about a first axis, and the material distributing spiral blade is wound around the rotating shaft along the first axis.

[0009] The first helical assembly includes a first rotating member and a first helical blade. The first rotating member is rotatably connected to the support assembly about a second axis. The first helical blade is wound around the first rotating member along the second axis, and the second axis intersects the first axis.

[0010] In some embodiments, along the first axis, the projections of the dispensing spiral blades and the projections of the first spiral blades have an overlapping area.

[0011] In some embodiments, the spiral paver further includes a first drive element, the output end of which is connected to the first rotating element for driving the first rotating element to rotate.

[0012] In some embodiments, the first rotating member is arranged along the height direction of the paver.

[0013] In some embodiments, at least a portion of the first helical blade is located outside the dispensing helical blade along the radial direction of the rotation axis.

[0014] In some embodiments, the support component includes:

[0015] Support base, connected to the fixing member;

[0016] The rotating seat is rotatably connected to the rotating shaft;

[0017] A cantilever is connected to the support base and the rotating base, and the first rotating component is sleeved on the outside of the cantilever and rotatably connected to the cantilever.

[0018] In some embodiments, the spiral paver further includes a second spiral assembly, the second spiral assembly comprising:

[0019] The second rotating member is rotatably connected to the support assembly about the third axis, and the second rotating member and the first rotating member are respectively located on opposite sides of the rotating axis along the radial direction, and the third axis intersects the first axis;

[0020] The second helical blade is wound around the second rotating member along the third axis.

[0021] In some embodiments, along the first axis, the projections of the dispensing spiral blades and the projections of the second spiral blades have an overlapping area.

[0022] In some embodiments, the spiral paver further includes a second drive member, the output end of which is connected to the second rotating member for driving the second rotating member to rotate.

[0023] In some embodiments, the second rotating member is arranged along the height direction of the paver.

[0024] In some embodiments, at least a portion of the second helical blade is located outside the dispensing helical blade along the radial direction of the rotation axis.

[0025] In some embodiments, the support component includes:

[0028] A cantilever is connected to the support base and the rotating base, and the first rotating component is sleeved on the outside of the cantilever and rotatably connected to the cantilever.

[0029] The boom and the cantilever are respectively located on opposite sides of the rotating shaft along the radial direction. The boom is connected to the rotating seat. The second rotating component is sleeved on the outside of the boom and is rotatably connected to the boom.

[0030] Secondly, embodiments of this application provide a paver, including the auger paver described in the first aspect.

[0031] The auger paver provided in this application uses the rotation of the auger to evenly distribute aggregate across the full width of the paver. During the rotation of the first auger assembly around the second axis in a set direction, the first auger blades can move the large aggregates that have sunk near the support assembly toward the side away from the roadbed, and move them to the middle or upper area of ​​the paver's distribution trough to supplement the gradation. This, to a certain extent, prevents segregation caused by gradation loss due to the sinking of large aggregates, improves the uniformity of aggregate paving, and ensures paving quality.

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0041] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0042] The terms “first,” “second,” and “third” (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0043] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0044] In related technologies, to ensure the stability of the auger, a support bracket is usually installed in the middle area of ​​the auger. This bracket connects the auger to the screeding device and provides support. However, after installing the support bracket, aggregate segregation is prone to occur at the bracket location, leading to uneven aggregate paving and affecting the paving quality. Segregation refers to the situation where large aggregates are not evenly and fully coated by smaller aggregates, resulting in uneven aggregate texture after hardening.

[0045] After repeated consideration and verification, the inventors discovered that due to the presence of the hanger, the material distribution spiral blades of the auger are discontinuous at the hanger, resulting in poor mixing effect near the hanger. Furthermore, due to the obstruction of the aggregate by the hanger, large aggregates form local deposits near the hanger, causing segregation.

[0046] In view of this, the inventors designed a spiral paver 100 and a paver. The spiral paver 100 adds a first spiral component 130 to the support component 110, so that the large aggregates that sink near the support component 110 can move upward under the pushing action of the first spiral component 130 and move to the middle or upper area of ​​the paver's distribution trough to supplement the gradation. To a certain extent, this prevents the segregation caused by the sinking of large aggregates and the resulting gradation loss, and ensures that the aggregates are evenly spread on the roadbed.

[0047] The spiral paver 100 and paver provided in the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, the auger paver 100 is applied to a paver. The auger paver 100 includes a support assembly 110, an auger 120, and a first auger assembly 130. The support assembly 110 is connected to the paver's fixing member 200. The auger 120 includes a rotating shaft 121 and a distributing auger blade 122. The rotating shaft 121 is rotatably connected to the support assembly 110 about a first axis 120a, and the distributing auger blade 122 is wound around the rotating shaft 121 along the first axis 120a. The first auger assembly 130 includes a first rotating member 131 and a first auger blade 132. The first rotating member 131 is rotatably connected to the support assembly 110 about a second axis 130a, and the first auger blade 132 is wound around the first rotating member 131 along the second axis 130a. The second axis 130a intersects the first axis 120a.

[0049] It is understood that the auger paver 100 may also include components such as a drive mechanism and an auger support. The auger support supports the rotating shaft 121 of the auger 120, with both ends of the rotating shaft 121 rotatably connected to the auger support around a first axis 120a. The material-distributing auger blades 122 of the auger 120 are fixedly connected to the rotating shaft 121, and can be fixed by means of snap-fit, welding, bolt connection, etc., which are not limited here. The drive mechanism is installed on the auger support and drives the rotating shaft 121 of the auger 120 to rotate around the first axis 120a. The rotating shaft 121 drives the material-distributing auger blades 122 to rotate around the first axis 120a. The drive mechanism can be a motor, etc.

[0050] When the auger paver 100 is in use, the rotating shaft 121 of the auger 120 is usually arranged horizontally, that is, the first axis 120a is usually arranged horizontally. When the rotating shaft 121 rotates, the material distribution auger blades 122 evenly distribute the aggregate conveyed by the paver's material collection and conveying system onto the full width of the paver.

[0051] The fixed component 200 of the paver refers to the component fixed relative to the rotating shaft 121, such as the auger support, the screed plate of the screed device, etc., which are not limited in this application. Those skilled in the art can connect the support component 110 to the corresponding component according to the specific circumstances.

[0052] The support assembly 110 is fixedly connected to the fixing member 200, and can be fixedly connected by means of snap-fit, welding, bolt connection, etc. When the auger 120 rotates, the support assembly 110 does not rotate with the auger 120.

[0053] The first helical blade 132 and the first rotating component 131 are fixedly connected, and can be fixedly connected by means of snap-fit, welding, bolt connection, etc., which are not limited here.

[0054] The first rotating member 131 is rotatably connected to the support assembly 110 about the second axis 130a. The intersection of the second axis 130a and the first axis 120a means that the second axis 130a and the first axis 120a are set at an angle, which can be a right angle, an acute angle or an obtuse angle, and is not limited in this application.

[0055] It is important to understand that when the auger paver 100 is in use, the first auger blade 132 extends into the aggregate, and the second axis 130a has a projected component in the height direction of the paver. In other words, when the auger paver 100 is in use, the second axis 130a cannot be horizontally arranged; that is, the second axis 130a must be set at a right angle, an acute angle, or an obtuse angle with the horizontal plane. This arrangement allows the first auger assembly 130 to rotate around the second axis 130a in the first rotation direction 130b, during which the first auger blade 132 can drive the aggregate to move away from the roadbed.

[0056] like Figure 3 As shown, when the auger paver 100 is in use, the first auger assembly 130 needs to rotate around the second axis 130a in the first rotation direction 130b. The first auger assembly 130 can be driven by a first driving component such as a motor, or it can be driven by aggregate. When the first auger assembly 130 is driven by a first driving component such as a motor, the motor can be mounted on the support assembly 110, and the output shaft of the motor can be fixedly connected to the first rotating component 131 of the first auger assembly 130, or the output shaft of the motor can be connected to the first auger assembly 130 through a transmission component such as a gear, so that the rotation of the motor output shaft drives the first rotating component 131 to rotate. When the auger 120 rotates around the first axis 120a in the second rotation direction 120b, the aggregate moves along the width direction of the paver under the drive of the auger 120. During the movement of the aggregate, it can apply a force to the first auger blade 132, thereby pushing the first auger blade 132, so that the first auger blade 132 rotates in the first rotation direction 130b. The first rotation direction 130b can be clockwise or counterclockwise, and is related to the rotation direction of the first helical blade 132, etc., and is not limited in this application. Similarly, the second rotation direction 120b can be clockwise or counterclockwise, and is related to the rotation direction of the distributing helical blade 122, etc., and is not limited in this application.

[0057] The auger paver 100 provided in this application, through the rotation of the auger 120, causes the aggregate to be evenly distributed across the full width of the paver. During the rotation of the first auger assembly 130 around the second axis 130a in the first rotation direction 130b, the first auger blades 132 cause the large aggregate pieces that have sunk below the support assembly 110 to move towards the side away from the roadbed, i.e., as... Figure 2 As shown, it moves upwards to the middle or upper part of the paver's distribution trough to supplement the gradation. This, to a certain extent, prevents segregation caused by the sinking of large aggregates and resulting in gradation loss, improves the uniformity of aggregate paving, and ensures paving quality.

[0058] In some embodiments, along the first axis 120a, the projections of the dispensing spiral blade 122 and the first spiral blade 132 have an overlapping area.

[0059] In other words, the projection of the distribution auger blade 122 along the first axis 120a at least partially overlaps with the projection of the first auger blade 132 along the first axis 120a, and at least a portion of the first auger blade 132 is located within the auger groove 122c formed by the distribution auger blade 122. During paving, the aggregate is mainly propelled by the distribution auger blade 122. To a certain extent, the thrust experienced by the aggregate located within the auger groove 122c is greater than the thrust experienced by the aggregate located outside the auger groove 122c. These embodiments, by arranging at least a portion of the first helical blade 132 within the helical groove 122c, enable the aggregate within the helical groove 122c, which experiences greater thrust, to better propel the first helical blade 132 around the second axis 130a in the first rotation direction 130b during the process of being pushed by the distributing helical blade 122. This ensures that during the process of the auger 120 rotating around the first axis 120a in the second rotation direction 120b to pave aggregate, the first helical blade 132 can be pushed by the aggregate to rotate around the second axis 130a in the first rotation direction 130b. These embodiments, by having the aggregate drive the first helical blade 132 to rotate, eliminate the need for a motor or other driving mechanism to drive the first helical blade 132, simplifying the structure of the auger paver 100, reducing its energy consumption, and facilitating its use.

[0060] In some embodiments, the spiral paver 100 further includes a first drive member (not shown in the figure), the output end of which is connected to the first rotating member 131 for driving the first rotating member 131 to rotate.

[0061] Specifically, the first driving element drives the first rotating element 131 to rotate around the second axis 130a in the first rotation direction 130b. These embodiments, through the arrangement of the first driving element, help ensure the continuous and stable rotation of the first spiral assembly 130, improving the uniformity of aggregate paving and guaranteeing paving quality. The first driving element can be a motor, etc., and is not limited in this application. If the first driving element is a motor, the output end is the motor's output shaft, which is connected to the first rotating element 131 via a transmission connection, allowing the output shaft to drive the first rotating element 131 to rotate. The transmission connection between the output shaft and the first rotating element 131 can be varied. For example, the output shaft and the first rotating element 131 can be connected by a coupling, allowing the output shaft to drive the first rotating element 131 to rotate, thus achieving a transmission connection between the output shaft and the first rotating element 131; another example is that a gear is fixedly arranged on both the output shaft and the first rotating element 131, the two gears mesh, and the rotation of the output shaft drives the two gears to rotate, thereby driving the first rotating element 131 to rotate, thus achieving a transmission connection between the output shaft and the first rotating element 131. The first drive unit can be installed on the support assembly 110 or on the fixed part 200 of the paver, such as the auger bracket or the screed plate of the screed device, etc., which are not limited in this application.

[0062] In some embodiments, the first rotating member 131 is arranged along the height direction of the paver. With this design, when the auger paver 100 is installed at the corresponding position on the paver, the second axis 130a is arranged along the height direction of the paver, that is, the second axis 130a is parallel to the height direction of the paver. The first auger assembly 130 pushes the aggregate upwards by the first auger blades 132. The second axis 130a is arranged along the height direction of the paver, so that the first auger blades 132 are wound around the first rotating member 131 along the height direction of the paver. This design helps to quickly transport large aggregates that have sunk near the support assembly 110 to the middle or upper part of the distribution trough, and can reduce the amount of large aggregates falling off during the upward transport by the first auger blades 132, ensuring the uniformity of aggregate mixing.

[0063] In some embodiments, at least a portion of the first helical blade 132 is located outside the distributing helical blade 122 along the radial direction of the rotation shaft 121. That is, the first helical blade 132 extends beyond the distributing helical blade 122 along the radial direction of the rotation shaft 121. Either the upper end or the lower end of the first helical blade 132 may extend beyond the distributing helical blade 122. When the upper end of the first helical blade 132 extends beyond the distributing helical blade 122, large aggregates that have sunk near the support assembly 110 can move to the top of the helical groove 122c under the action of the first helical blade 132; when the lower end of the first helical blade 132 extends beyond the distributing helical blade 122, large aggregates that have sunk to the bottom below the helical groove 122c can return to the helical groove 122c under the action of the first helical blade 132. Both of these situations help to ensure uniform mixing of the aggregates near the support assembly 110, guaranteeing the uniformity of aggregate mixing.

[0064] In some embodiments, the first helical blade 132 is located above the rotating shaft 121, and the upper end of the first helical blade 132 extends out of the dispensing helical blade 122.

[0065] The structure of the support component 110 is varied. The support component 110 can be a rod, with one end of the rod fixedly connected and the other end connected to the rotating shaft 121.

[0066] In some embodiments, the support assembly 110 includes a support base 111, a rotating base 112, and a cantilever 113. The support base 111 is connected to the fixing member 200. The rotating base 112 is rotatably connected to the rotating shaft 121. The cantilever 113 is connected to the support base 111 and the rotating base 112, and a first rotating member 131 is sleeved on the cantilever 113 and rotatably connected to the cantilever 113.

[0067] The support base 111 is fixedly connected to the fixing member 200. One side of the cantilever 113 is fixedly connected to the support base 111, and the other side is fixedly connected to the rotating seat 112. The support base 111 supports the cantilever 113, the cantilever 113 supports the rotating seat 112, and the rotating seat 112 supports the rotating shaft 121. The first rotating member 131 is sleeved on the outside of the cantilever 113 and rotatably connected to the cantilever 113. The support assembly 110 includes components such as the support base 111, the rotating seat 112, and the cantilever 113, allowing these components to be processed individually and then assembled to form the support assembly 110. This reduces the manufacturing difficulty of the support assembly 110 and facilitates its processing. The first rotating member 131 is a hollow tube, which is sleeved on the outside of the cantilever 113, preventing the aggregate from being blocked by the cantilever 113. This helps to reduce the contact area between the support assembly 110 and the aggregate, thereby reducing the possibility or degree of segregation.

[0068] In some embodiments, the cantilever 113 has a circular cross-section, and the first rotating member 131 has an annular cross-section. The inner diameter of the first rotating member 131 is larger than the diameter of the cantilever 113, so that the first rotating member 131 is rotatably connected to the cantilever 113. The first rotating member 131 is located between the support base 111 and the rotating base 112, which respectively limit the upper and lower ends of the first rotating member 131 to prevent it from detaching from the cantilever 113.

[0069] In some embodiments, the spiral paver 100 further includes a second spiral assembly 140, which includes a second rotating member 141 and a second spiral blade 142. The second rotating member 141 is rotatably connected to the support assembly 110 about a third axis 140a, and the second rotating member 141 and the first rotating member 131 are respectively located on opposite sides of the rotation axis 121 along the radial direction, and the third axis 140a intersects the first axis 120a. The second spiral blade 142 is wound around the second rotating member 141 along the third axis 140a.

[0070] The second rotating member 141 and the first rotating member 131 are respectively located on opposite sides of the rotating shaft 121 along the radial direction, so that the second helical blade 142 and the first helical blade 132 are respectively located on opposite sides of the rotating shaft 121 along the radial direction. This ensures that the second helical blade 142 and the first helical blade 132 can respectively mix the aggregate on opposite sides of the rotating shaft 121 along the radial direction, ensuring the mixing effect of the aggregate near the support assembly 110. When the spiral paver 100 is in use, one of the second rotating member 141 and the first rotating member 131 is located on the upper side of the rotating shaft 121, and the other is located on the lower side of the rotating shaft 121. For the convenience of the following description, the following description takes the second rotating member 141 being located on the lower side of the rotating shaft 121 and the first rotating member 131 being located on the upper side of the rotating shaft 121 as an example. The intersection of the third axis 140a and the first axis 120a means that the third axis 140a and the first axis 120a are set at an angle, which can be a right angle, an acute angle, or an obtuse angle, and is not limited in this application. When the auger paver 100 is in use, both the first auger blade 132 and the second auger blade 142 extend into the aggregate, and the third axis 140a also has a projected component in the height direction of the paver. This means that the third axis 140a cannot be horizontally arranged during use; it must be perpendicular, acute, or obtuse to the horizontal plane. This arrangement allows the second auger assembly 140 to rotate around the third axis 140a in the third rotation direction 140b, while the second auger blade 142 also drives the aggregate to move away from the roadbed.

[0071] When the auger paver 100 is in use, the second auger assembly 140 needs to rotate around the third axis 140a in the third rotation direction 140b. The second auger assembly 140 can be driven by a second driving component such as a motor, or it can be driven by aggregate. When the second auger assembly 140 is driven by a second driving component such as a motor, the motor can be mounted on the support assembly 110, and the output shaft of the motor can be fixedly connected to the second rotating component 141 of the second auger assembly 140, or the output shaft of the motor can be connected to the second auger assembly 140 through a transmission such as gears, so that the rotation of the motor output shaft drives the first rotating component 131 to rotate. When the auger 120 rotates around the first axis 120a in the second rotation direction 120b, the aggregate moves along the width direction of the paver under the drive of the auger 120. During the movement of the aggregate, it can apply a force to the second auger blade 142, thereby pushing the second auger blade 142 to rotate in the third rotation direction 140b. The third rotation direction 140b can be clockwise or counterclockwise. The third rotation direction 140b is related to the rotation direction of the second helical blade 142, etc., and is not limited in this application.

[0072] With the above design, the auger 120 rotates, causing the aggregate to be evenly distributed across the full width of the paver. The first auger assembly 130 rotates around the first rotation direction 130b, and the second auger assembly 140 rotates around the third rotation direction 140b. This causes the large aggregates that have sunk below the support assembly 110 to move away from the roadbed under the combined action of the first auger blade 132 and the second auger blade 142. Figure 2 As shown, the upward movement is specifically: the large aggregate on the lower side of the rotating shaft 121 is transported to the middle of the paver's distribution trough by the second helical blade 142, while the large aggregate on the upper side of the rotating shaft 121 is transported to the top of the paver's distribution trough by the first helical blade 132. This replenishes the gradation and, to a certain extent, prevents the large aggregate from sinking and causing segregation due to gradation loss, thereby improving the uniformity of aggregate paving and ensuring paving quality.

[0073] In some embodiments, along the first axis 120a, the projections of the dispensing spiral blade 122 and the second spiral blade 142 have an overlapping area.

[0074] In other words, the projection of the distribution auger blade 122 along the first axis 120a at least partially overlaps with the projection of the second auger blade 142 along the first axis 120a, and at least a portion of the second auger blade 142 is located within the auger groove 122c formed by the distribution auger blade 122. During paving, the aggregate is mainly propelled by the distribution auger blade 122. To a certain extent, the thrust experienced by the aggregate located within the auger groove 122c is greater than the thrust experienced by the aggregate located outside the distribution auger blade 122. These embodiments, by arranging at least a portion of the second helical blade 142 within the helical groove 122c, enable the aggregate within the helical groove 122c, which experiences greater thrust, to better propel the second helical blade 142 around the third axis 140a in the third rotation direction 140b during the process of being pushed by the distributing helical blade 122. This ensures that during the process of the auger 120 rotating around the first axis 120a in the second rotation direction 120b to pave aggregate, the first helical blade 132 can be pushed by the aggregate to rotate around the third axis 140a in the third rotation direction 140b. These embodiments, by using the aggregate to propel the second helical blade 142, eliminate the need for a motor or other driving mechanism to drive the second helical blade 142, simplifying the structure of the auger paver 100, reducing its energy consumption, and facilitating its use.

[0075] In some embodiments, the spiral paver 100 further includes a second drive member (not shown in the figure), the output end of which is connected to the second rotating member 141 for driving the second rotating member 141 to rotate.

[0076] Specifically, the second driving element drives the second rotating element 141 to rotate around the third axis 140a in the third rotation direction 140b. These embodiments, through the arrangement of the second driving element, help ensure the continuous and stable rotation of the second spiral assembly 140, improving the uniformity of aggregate paving and guaranteeing paving quality. The second driving element can be a motor, etc., and is not limited in this application. If the second driving element is a motor, the output end is the motor's output shaft, and the output shaft is connected to the second rotating element 141, allowing the output shaft to drive the second rotating element 141 to rotate. The transmission connection between the output shaft and the second rotating element 141 can be varied. For example, the output shaft and the second rotating element 141 can be connected by a coupling, so that the output shaft drives the second rotating element 141 to rotate, thus achieving a transmission connection between the output shaft and the second rotating element 141; another example is that a gear is fixedly arranged on both the output shaft and the first rotating element 131, and the two gears mesh. The rotation of the output shaft drives the two gears to rotate, thereby driving the second rotating element 141 to rotate, thus achieving a transmission connection between the output shaft and the second rotating element 141. The second drive component can be installed on the support assembly 110 or on the fixed component 200 of the paver, such as the auger bracket or the screed plate of the screed device, etc., which are not limited in this application.

[0077] In some embodiments, the second rotating member 141 is arranged along the height direction of the paver. With this arrangement, when the auger paver 100 is installed at the corresponding position on the paver, the third axis 140a is arranged along the height direction of the paver, that is, the third axis 140a is parallel to the height direction of the paver. The second auger assembly 140 pushes the aggregate upwards by the second auger blades 142. The third axis 140a is arranged along the height direction of the paver, so that the second auger assembly 140 is wound around the first rotating member 131 along the height direction of the paver. This design helps to quickly transport large aggregates that have sunk near the support assembly 110 to the center of the distribution trough, and can reduce the amount of large aggregates falling off during the upward transport by the second auger blades 142, ensuring the uniformity of aggregate mixing.

[0078] In some embodiments, at least a portion of the second helical blade 142 is located outside the distributing helical blade 122 along the radial direction of the rotation shaft 121. That is, the second helical blade 142 extends beyond the distributing helical blade 122 along the radial direction of the rotation shaft 121. Either the upper end or the lower end of the second helical blade 142 may extend beyond the distributing helical blade 122. When the upper end of the second helical blade 142 extends beyond the distributing helical blade 122, large aggregates that have sunk near the support assembly 110 can move to the top of the helical groove 122c under the influence of the second helical blade 142; when the lower end of the second helical blade 142 extends beyond the distributing helical blade 122, large aggregates that have sunk to the bottom below the helical groove 122c can return to the helical groove 122c under the influence of the second helical blade 142. Both of these situations help to ensure uniform mixing of the aggregates near the support assembly 110, guaranteeing the uniformity of aggregate mixing.

[0079] In some embodiments, the first helical blade 132 is located above the rotating shaft 121, and the upper end of the first helical blade 132 extends out of the dispensing helical blade 122. The second helical blade 142 is located below the rotating shaft 121, and the lower end of the second helical blade 142 extends out of the dispensing helical blade 122.

[0080] In some embodiments, the third axis 140a and the second axis 130a are coaxially arranged.

[0081] The spiral directions of the first helical blade 132 and the second helical blade 142 may be the same or different, and are not limited in this application.

[0082] In some embodiments, the first helical blade 132 and the second helical blade 142 have the same helical direction. In these embodiments, the first rotation direction 130b and the third rotation direction 140b are in the same direction, so that when the first helical blade 132 and the second helical blade 142 rotate, they can both drive the aggregate to move upward.

[0083] like Figure 4 As shown, in some embodiments, the support assembly 110 includes a support base 111, a rotating base 112, a cantilever 113, and a boom 114. The support base 111 is connected to the fixing member 200. The rotating base 112 is rotatably connected to the rotating shaft 121. The cantilever 113 is connected to the support base 111 and the rotating base 112, and a first rotating member 131 is sleeved on the outside of the cantilever 113 and rotatably connected to the cantilever 113. The boom 114 and the cantilever 113 are located on opposite radial sides of the rotating shaft 121, the boom 114 is connected to the rotating base 112, and a second rotating member 141 is sleeved on the outside of the boom 114 and rotatably connected to the boom 114.

[0084] The support base 111 is fixedly connected to the fixing member 200. One side of the cantilever 113 is fixedly connected to the support base 111, and the other side is fixedly connected to the rotating seat 112. The support base 111 supports the cantilever 113, the cantilever 113 supports the rotating seat 112, and the rotating seat 112 supports the rotating shaft 121. The first rotating member 131 is sleeved on the outside of the cantilever 113 and rotatably connected to the cantilever 113. The cantilever 113 and the boom 114 are located on the upper and lower sides of the rotating shaft 121, respectively. The boom 114 is fixedly connected to the rotating seat 112, and the second rotating member 141 is sleeved on the outside of the boom 114 and rotatably connected to the boom 114. The support assembly 110 includes components such as the support base 111, the rotating seat 112, the cantilever 113, and the boom 114. These components can be processed individually and then assembled to form the support assembly 110, which can reduce the manufacturing difficulty of the support assembly 110 and facilitate its processing. The first rotating component 131 is a hollow tube, fitted over the cantilever 113, preventing the aggregate from being obstructed by the cantilever 113. This helps reduce the contact area between the support assembly 110 and the aggregate, thereby reducing the likelihood or degree of segregation. Similarly, the second rotating component 141 is a hollow tube, fitted over the boom 114, preventing the aggregate from being obstructed by the boom 114. This helps reduce the contact area between the support assembly 110 and the aggregate, thereby reducing the likelihood or degree of segregation.

[0085] In some embodiments, the cantilever 113 has a circular cross-section, and the first rotating member 131 has an annular cross-section. The inner diameter of the first rotating member 131 is larger than the diameter of the cantilever 113, so that the first rotating member 131 is rotatably connected to the cantilever 113. The first rotating member 131 is located between the support base 111 and the rotating base 112, which respectively limit the upper and lower ends of the first rotating member 131 to prevent it from detaching from the cantilever 113.

[0086] In some embodiments, the boom 114 has a circular cross-section, and the second rotating member 141 has an annular cross-section. The inner diameter of the second rotating member 141 is larger than the diameter of the boom 114, so that the second rotating member 141 is rotatably connected to the boom 114. In these embodiments, a limiting member (not shown in the figure) can be provided at the end of the boom 114 away from the rotating seat 112. The limiting member is detachably connected to the boom 114. The second rotating member 141 is located between the rotating seat 112 and the limiting member. The rotating seat 112 and the limiting member respectively limit the upper and lower ends of the second rotating member 141 to prevent the second rotating member 141 from disengaging from the cantilever 113. The limiting member can be a limiting pin, etc., and is not limited in this application.

[0087] Understandably, when the spiral paver 100 is in use, there are gaps between the boom 114, the second rotating component 141, and the second spiral blade 142 and the roadbed, so that they do not come into contact with the roadbed, in order to ensure that the paving work can proceed smoothly.

[0088] In some embodiments, a shaft hole is provided in the middle of the rotating seat 112, and the rotating shaft 121 passes through the shaft hole to be rotatably connected to the rotating seat 112.

[0089] In some embodiments, such as Figure 4 As shown, the cantilever 113 and the boom 114 are both arranged along the height direction of the paver. The rotating seat 112 is located between the cantilever 113 and the boom 114 and is fixedly connected to the cantilever 113 and the boom 114. The support seat 111 is located above the cantilever 113 and is fixedly connected to the cantilever 113.

[0090] The working principle of the spiral paver 100 of this application is described below:

[0091] When the auger 120 rotates around the first axis 120a in the second rotation direction 120b, the aggregate moves along the width direction of the paver under the drive of the auger 120. During the movement of the aggregate, it exerts a force on the first auger blade 132 and the second auger blade 142, pushing the first auger blade 132 to rotate in the first rotation direction 130b and pushing the second auger blade 142 to rotate in the third rotation direction 140b. The large aggregates that sink under the rotation of the first auger blade 132 and the second auger blade 142 move toward the side away from the roadbed and move to the middle or upper area of ​​the paver's distribution trough to supplement the gradation, thereby improving the uniformity of aggregate paving and ensuring paving quality.

[0092] Based on the same inventive concept, this application also provides a paver, which includes the above-described auger paver 100.

[0093] Since the paver includes the aforementioned auger paver 100, it naturally possesses all the beneficial effects of the auger paver 100, which will not be elaborated upon here.

[0094] A paver typically includes a frame, power system (including engine and hydraulic transmission system), walking system, electrical control system, material receiving and conveying system (including front push roller, receiving hopper, scraper conveyor, and auger distributor), leveling system, and screed device. After a dump truck delivers asphalt and other aggregates into the receiving hopper, the scraper conveyor transports the aggregates to the distribution system, where the auger paver spreads them evenly. Finally, the screed compacts and levels the surface, completing the high-precision road paving. The structure of these devices and the connections between them are well-known to those skilled in the art and will not be elaborated upon here.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
