Description

Technical Field

[0001] The invention relates to the technical field of pavers, and in particular to a continuous feeding device for pavers. Background Art

[0002] A paver refers to a mechanical equipment used for paving asphalt pavement. When the paver is working, the hopper first receives the asphalt mixture brought by the dump truck, and then transports it backward to the spiral distributor through the scraper conveyor. The spiral distributor distributes the asphalt mixture evenly in front of the ironing plate. The vibrating mechanism in the ironing plate generates high-frequency vibration to make the asphalt mixture dense. Then the ironing plate further compacts and levels the asphalt mixture with its own weight and appropriate elevation angle, thereby completing high-quality asphalt pavement paving operations.

[0003] After searching, a Chinese patent with authorization announcement number CN115821685B discloses a continuous feeding device for a paver, including a frame and a conveyor belt installed on the frame and extending to the paver hopper to transport materials. A buffer storage bin is provided on the frame in front of the conveyor belt. The buffer storage bin has a discharge port and a buffer storage chamber. Materials are poured into the buffer storage bin and first stored in the buffer storage chamber. After the buffer storage chamber is full, it overflows and is discharged to the conveyor belt from the discharge port. The buffer storage chamber is opened during the alternating discharge of the material truck, and the material is discharged to the conveyor belt through the discharge port. The buffer storage chamber has a material holding capacity to keep the material continuously discharged to the conveyor belt during the alternating discharge of the material truck.

[0004] The above-mentioned patent utilizes the cooperation of a buffer storage chamber and a conveyor belt to realize continuous feeding of the paver. However, when the paver performs asphalt mixture paving operations under low temperature conditions, since the asphalt mixture must first enter the buffer storage chamber, and then rely on the conveyor belt to transfer the asphalt mixture in the buffer storage chamber to the paver hopper, this process extends the entire transportation path. Affected by the low temperature factor, the transportation time of the asphalt mixture is greatly increased, and its internal heat loss is large, causing the asphalt in the asphalt mixture to gradually harden, thereby causing the bonding force between the asphalt and the aggregate in the asphalt mixture to weaken. After the paving operation is completed, cracks or potholes are prone to appear on the asphalt pavement, affecting the quality of the asphalt pavement. Therefore, the present application provides a continuous feeding device for a paver to meet the needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a continuous feeding device for a paver to solve the problem that the asphalt mixture is greatly affected by low temperature during transportation, causing the asphalt in the asphalt mixture to gradually harden, resulting in weakened adhesion between the asphalt and the aggregate, and cracks or potholes are prone to appear on the asphalt pavement after the paving operation is completed, thereby affecting the quality of the asphalt pavement.

As the asphalt mixture falls in the heating chamber, the driving element drives the breaking bar to reciprocate up and down to break up the clumped asphalt mixture, and the broken up asphalt mixture continues to fall to the heating plate 1 and the heating plate 2, and the breaking bar drives the heating plate 1 and the heating plate 2 to swing back and forth up and down through the connecting rod, while heating the asphalt mixture, the asphalt mixture passes smoothly from the heating plate 1 and the heating plate 2, and the heated asphalt mixture falls from the discharge port into the feed hopper of the paver, realizing continuous feeding.

[0007] Preferably, the scattered strips are in the shape of an isosceles triangle.

[0008] Preferably, a plurality of notches are provided on the top of the scattering strip, and an inverted V-shaped surface is provided at the bottom of the inner wall of the notch.

[0009] Preferably, the bottom of the scattering strip is provided with a positive V-shaped surface.

[0010] Preferably, baffles are fixed on opposite sides of the breaking strip, and the top of the baffle is provided with inclined plane 1 and inclined plane 2 connected in sequence, inclined plane 2 is connected to the side of the breaking strip, and inclined plane 1 is provided with a plurality of notches evenly spaced.

[0011] Preferably, the tops of the heating plate 1 and the heating plate 2 are both provided with grooves, and the bottoms of the inner walls of the grooves are provided with inclined guiding surfaces.

[0012] Preferably, dividing strips are fixed on opposite sides of the inner wall of the heating chamber, and breaking pieces are fixed on one side of the heating plate 1 and the heating plate 2 close to the dividing strips.

[0013] Preferably, a third slope is provided on the top of the scattering piece, and the height of the scattering strip on the side close to the rotating shaft is smaller than the height of the scattering strip on the side away from the rotating shaft.

[0014] Preferably, a through groove is provided on one side of the heating plate 1 and the heating plate 2 close to the dividing strip, a fixed shaft is fixed in the through groove, and the bottom of the connecting rod is rotatably sleeved on the fixed shaft.

[0015] Preferably, a guide sleeve is fixed on the top of the feed cover, and the bent rod is slidably connected to the inner wall of the guide sleeve.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, the insulation cover, the heating element, the breaking-up strips and the heating plate 1 are arranged, the insulation cover is used to keep the asphalt mixture transported by the feeder warm. After the feeder feeds it into the heating element, the falling asphalt mixture is broken up by the breaking-up strips driven by the driving element so that it can be fully and evenly heated by the heating plate 1, the heating plate 2 and the heating element. When it falls to the heating plate 1 and the heating plate 2, the breaking-up strips make the heating plate 1 and the heating plate 2 swing back and forth up and down, which can adapt to the low temperature environment while heating and preventing material blockage, enhance the adhesion between asphalt and aggregate, prevent road cracks or potholes, and improve the paving quality.

[0017] Through the setting of the driving member, the driving member can drive the scattering bar to move upward for a specific distance, and then make it reciprocate up and down. When the scattering bar moves upward for this distance, the connecting rod will drive the heating plate 1 and the heating plate 2 to rotate upward, so that the distance between the heating plate 1 and the heating plate 2 and the inner wall of the heating chamber is reduced. When the asphalt mixture falls from the heating chamber, its residence time in the heating chamber is increased, thereby effectively improving the heating effect of the asphalt mixture, so that it can adapt well to the weather environment with lower temperature.

[0018] Through the setting of the notch, when the agglomerated asphalt mixture contacts the top of the breakup strip, given that the breakup strip is in the shape of an isosceles triangle with a notch on the top, part of the asphalt mixture will contact the solid part of the top of the breakup strip and produce a dispersion effect, while the rest of the asphalt mixture falls directly into the notch due to the design of the notch, thereby achieving initial dispersion of the asphalt mixture. The asphalt mixture that falls into the notch is further refined and dispersed under the action of the inverted V-shaped surface. Through the coordinated cooperation of the isosceles triangle shape and the notch, the dispersion capacity of the agglomerated asphalt mixture is greatly improved, thereby further improving the uniformity and comprehensiveness of the heating of the asphalt mixture.

[0019] Through the setting of the baffle bar, the asphalt mixture falling along the oblique edge of the breaking up bar contacts with the baffle bar and is further dispersed under the action of the notch on the baffle bar. At the same time, the design of the inclined surface on the baffle bar effectively enhances the blocking ability of the asphalt mixture passing through the baffle bar, so that part of the clumped asphalt mixture is intercepted at the baffle bar, and the remaining part of the clumped asphalt mixture falls from the baffle bar, which significantly improves the ability to break up the clumped asphalt mixture, thereby further improving the effect of breaking up the clumped asphalt mixture, and further improving the uniformity and comprehensiveness of the heating of the asphalt mixture.

[0020] By setting the breaking pieces and dividing strips, when the asphalt mixture falls from the heating plate one and the heating plate two, it can be further dispersed under the action of the breaking pieces and the dividing strips, thereby further improving the ability to break up the agglomerated asphalt mixture, and further making the heating of the asphalt mixture more sufficient and comprehensive.

[0021] Through the setting of the groove and the guide surface, when the asphalt mixture falls into the groove, it can flow downward smoothly under the guidance of the guide surface, preventing the asphalt mixture from accumulating in the groove, avoiding the influence of the accumulation on the up and down reciprocating swing of the heating plate 1 and the heating plate 2, and making the up and down reciprocating swing of the heating plate 1 and the heating plate 2 more stable and smooth.

[0028] like Figure 1-Figure 9 As shown, an embodiment of the present invention provides a continuous feeding device for a paving machine, comprising a feeder 1, and further comprising: The heating mechanism 4 includes a heating element 5 fixed to the end of the frame of the feeder 1, and the heating element 5 is composed of a plurality of heating plates spliced ​​together. A heat preservation cover 2 is installed on the conveyor belt of the feeder 1, and the heat preservation cover 2 is buckled on the frame at the conveyor belt of the feeder 1 by buckles. A feed cover 3 is fixed on the top of the heating element 5, and a driving member 13 is fixed on the top of the feed cover 3. The driving member 13 is a cylinder, and the movement of the driving member 13 can be controlled by a PLC control system. A connecting frame 12 is fixed to the telescopic end of the driving member 13, and a plurality of bent rods 11 are fixed to the bottom of the connecting frame 12. A plurality of heating chambers 6 are arranged inside the heating element 5, and a plurality of breaking strips 7 are arranged in the heating chamber 6. The bottom of the bent rod 11 movably penetrates the feed cover 3 and is fixedly connected to the bottom of the scattering bar 7. The number of the scattering bars 7 can be two, and each scattering bar 7 corresponds to two curved rods 11. The connecting frame 12 can be composed of two vertical rods and a horizontal rod. The vertical rod is used to connect the two curved rods 11 on the same side. The horizontal rod is fixed on the vertical rod and connected to the telescopic end of the driving member 13. A rotating shaft 27 is fixed in the heating chamber 6. The heating plate 18 and the heating plate 2 19 are respectively rotatably sleeved on the rotating shaft 27. The heating plate 1 18 and the heating plate 2 19 are both located below the scattering bar 7. A circular shaft 22 is fixed on the side of the curved rod 11. The heating plate 1 18 and the heating plate 2 19 are rotatably connected to the two circular shafts 22 in the same heating chamber 6 through the rotating shaft 27. The bottom and side of the heating element 5 are provided with discharge ports; During operation, the feeder 1 insulates the asphalt mixture through the heat preservation cover 2 during the transportation process, effectively reducing the heat loss to the external environment, maintaining the temperature of the asphalt mixture, and preventing it from cooling too quickly in a low temperature environment, thereby maintaining the good fluidity and adhesion of the asphalt. The feeder 1 feeds the asphalt mixture into the heating chamber 6 of the heating element 5. During the asphalt mixture falling in the heating chamber 6, the driving element 13 drives the breaking strip 7 to reciprocate up and down to break up the agglomerated asphalt mixture. The broken asphalt mixture continues to fall to the heating plate 18 and the heating plate 19. At the hot plate 19, the breaking strip 7 drives the heating plate 18 and the heating plate 2 19 to swing back and forth up and down through the connecting rod 24, so that the asphalt mixture can be heated and pass smoothly from the heating plate 1 18 and the heating plate 2 19, and the heated asphalt mixture falls from the discharge port into the feed hopper of the paver, so as to realize continuous feeding, break up the asphalt mixture and then heat it, so that the heating of the asphalt mixture is more sufficient and uniform, improve the adhesion between asphalt and aggregate in the asphalt mixture, prevent road cracks or potholes, and improve the paving quality.

[0029] like Fig. 9As shown, in the present embodiment, the breaking-up strip 7 is in the shape of an isosceles triangle. When the isosceles triangle comes into contact with the agglomerated asphalt mixture, the sharp corner at the top of the breaking-up strip 7 can be inserted into the interior of the agglomerated asphalt mixture, and force is applied evenly from both sides, so as to more effectively destroy the integrity of the agglomerated asphalt mixture during the up and down reciprocating motion. At the same time, the symmetrical structure of the isosceles triangle has good stability, and can maintain a precise motion trajectory during frequent motion, so as to continuously and stably break up the agglomerated asphalt mixture, thereby greatly improving the pretreatment effect of the asphalt mixture, laying a solid foundation for subsequent uniform heating and high-quality paving, and further reducing the hidden dangers of road quality caused by the agglomeration of the asphalt mixture.

[0030] like Figure 7 As shown, in the present embodiment, a plurality of notches 8 are provided on the top of the breaking strip 7, and an inverted V-shaped surface 9 is provided on the bottom of the inner wall of the notch 8. When the agglomerated asphalt mixture contacts the top of the breaking strip 7, due to the isosceles triangle shape of the breaking strip 7 with the notches 8, part of the asphalt mixture is physically contacted and dispersed with the top of the breaking strip 7, and part of the asphalt mixture falls into it through the notches 8, achieving preliminary dispersion first, and the asphalt mixture falling into the notches 8 is further refined and dispersed under the action of the inverted V-shaped surface 9. The isosceles triangle and the notch 8 cooperate with each other, which greatly improves the dispersion ability of the agglomerated asphalt mixture, thereby enhancing the uniformity and comprehensiveness of the heating of the asphalt mixture.

[0031] like Fig. 9 As shown, in the present embodiment, a positive V-shaped surface 10 is provided at the bottom of the breaking strip 7. When the bottom of the breaking strip 7 contacts with the asphalt mixture, the positive V-shaped surface 10 can disperse the asphalt mixture in contact, thereby avoiding flattening the asphalt mixture. The special shape structure generates an outward thrust on the asphalt mixture, causing the asphalt mixture to disperse to both sides. Through the synergistic effect with the top structure of the breaking strip 7, the ability to break up the agglomerated asphalt mixture is improved in all directions, ensuring the uniform dispersion of the asphalt mixture before heating, facilitating the uniform transfer and absorption of heat during the subsequent heating process, reducing the risk of uneven heating due to local accumulation or compaction of the asphalt mixture, and ensuring the flatness and quality stability of the asphalt pavement.

[0032] like Figure 7 and Fig. 9As shown, in this embodiment, the two opposite sides of the scattering strip 7 are fixed with baffles 14, and the top of the baffle 14 is provided with a slope 15 and a slope 2 17 connected in sequence, and the slope 2 17 is connected to the side of the scattering strip 7. The slope 15 is provided with a plurality of gaps 16 evenly distributed at intervals. When the asphalt mixture falling along the oblique side of the scattering strip 7 contacts the baffle 14, the gaps 16 further divide and disperse the asphalt mixture, thereby increasing the crushing degree and dispersion uniformity of the asphalt mixture, and the slope 15 enhances the blocking ability of the asphalt mixture, so that the agglomerated asphalt is Part of the mixture is intercepted at the baffle 14, and the remaining part continues to fall. This selective interception and release design significantly improves the ability to break up agglomerated asphalt mixtures, and further improves the dispersion of the asphalt mixture, which is not only conducive to subsequent uniform heating, but also can reduce the local overheating or insufficient heating problems that may be caused by the agglomeration of large particles during the heating process, thereby improving the quality stability of the asphalt pavement. The second inclined surface 17 is connected to the oblique edge of the side of the breaking strip 7, which increases the contact area between the baffle 14 and the breaking strip 7, and improves the connection strength between the baffle 14 and the breaking strip 7.

[0033] like Figure 6 As shown, in the present embodiment, a groove 20 is provided at the top of each of the heating plates 18 and 19, and an inclined guiding surface 21 is provided at the bottom of the inner wall of the groove 20. When the asphalt mixture falls into the groove 20, it can flow downward smoothly under the guidance of the guiding surface 21, thereby preventing the asphalt mixture from accumulating in the groove 20, thus avoiding obstruction to the up and down reciprocating swing of the heating plates 18 and 19 due to the accumulation, and enabling the heating plates 18 and 19 to operate stably.

[0034] like Figure 4-Figure 6 As shown, in the present embodiment, dividing strips 28 are fixed on opposite sides of the inner wall of the heating chamber 6, and breaking pieces 25 are fixed on the side of the heating plate 1 18 and the heating plate 2 19 close to the dividing strips 28. The dividing strips 28 in the heating chamber 6 and the breaking pieces 25 on the heating plates 1 18 and 19 play an important role in further dispersing and heating the asphalt mixture. When the asphalt mixture falls from the heating plates 1 18 and 19, the asphalt mixture is further dispersed under the synergistic action of the breaking pieces 25 and the dividing strips 28, so that the heating of the asphalt mixture is more sufficient and comprehensive.

[0035] like Figure 8As shown, in the present embodiment, a slope three 26 is provided on the top of the scattering piece 25, and the height of the scattering strip 7 on the side close to the rotating shaft 27 is smaller than the height of the scattering strip 7 on the side away from the rotating shaft 27. When the asphalt mixture falls through the scattering piece 25, the slope three 26 causes the asphalt mixture to be subjected to upward and outward forces, thereby improving the blocking ability of the asphalt mixture passing through the scattering piece 25, increasing the collision and friction between the asphalt mixture and the scattering piece 25, promoting the crushing and dispersion of the asphalt mixture, and further improving the dispersion effect of the asphalt mixture.

[0036] like Figure 4 and Figure 6 As shown, in the present embodiment, a through groove 23 is provided on one side of the heating plate 18 and the heating plate 2 19 close to the dividing strip 28, a fixed shaft is fixed in the through groove 23, and the bottom of the connecting rod 24 is rotatably sleeved on the fixed shaft. The two connecting rods 24 in the same heating chamber 6 are rotatably connected to the heating plate 1 18 and the heating plate 2 19 respectively through the fixed shaft in the through groove 23, so that the heating plate 1 18 and the heating plate 2 19 are driven to reciprocate up and down through the connecting rod 24 during the reciprocating up and down motion of the beating strip 7.

[0037] like Figure 1 and Figure 2 As shown, in this embodiment, a guide sleeve 29 is fixed to the top of the feed cover 3, and the bent rod 11 is slidably connected to the inner wall of the guide sleeve 29. The guide sleeve 29 guides the movement of the bent rod 11, thereby guiding the up and down reciprocating motion of the breaking bar 7, making the up and down reciprocating motion of the breaking bar 7 more stable and smooth.

[0038] Working principle: When used in a low temperature environment, the feeder 1 is started. During the operation of the feeder 1, the heat preservation cover 2 on the conveyor belt first insulates the asphalt mixture to reduce heat loss, and then the asphalt mixture is fed into the heating element 5 of the heating mechanism 4; When the asphalt mixture reaches the heating mechanism 4, it first enters the heating chamber 6 of the heating element 5. At this time, the driving member 13 located on the top of the feed cover 3 is started, and the piston rod of the driving member 13 reciprocates up and down to drive the connecting frame 12 to reciprocate up and down. The connecting frame 12 drives the breaking strip 7 to reciprocate up and down through the bending rod 11; By utilizing the isosceles triangle shape of the breaking strip 7 and the coordination with the notch 8, when the breaking strip 7 contacts the agglomerated asphalt mixture, the agglomerated asphalt mixture is dispersed. Specifically, when the agglomerated asphalt mixture contacts the top of the breaking strip 7, a part of the asphalt mixture interacts with the solid part of the top of the breaking strip 7 and begins to disperse under the shear force and impact force of the up and down movement of the breaking strip 7. At the same time, another part of the asphalt mixture directly falls into the notch 8 due to the existence of the notch 8 and is further refined and dispersed under the guidance of the inverted V-shaped surface 9. In addition, the positive V-shaped surface 10 at the bottom of the breaking strip 7 can also disperse the asphalt mixture in contact during the downward movement of the breaking strip 7 to prevent the asphalt mixture from being flattened. When the asphalt mixture falling along the oblique edge of the breaking strip 7 contacts the stop bar 14, the notch 16 further divides and disperses the asphalt mixture, and the inclined surface 15 enhances the blocking ability of the asphalt mixture, so that part of the agglomerated asphalt mixture is intercepted at the stop bar 14, and the remaining part continues to fall, thereby significantly improving the ability to break up the agglomerated asphalt mixture, further improving the dispersion degree of the asphalt mixture, and laying a solid foundation for subsequent uniform heating; When the scattering bar 7 reciprocates up and down, the round shaft 22 on the bent rod 11 and the connecting rod 24 cooperate to drive the heating plate 18 and the heating plate 2 19 to reciprocate up and down with the rotating shaft 27 as the axis. The up and down reciprocating swing allows the asphalt mixture to pass smoothly through the heating plate 18 and the heating plate 2 19 to prevent material blockage and achieve heating of the passing asphalt mixture. At the same time, the groove 20 opened on the top of the heating plate 18 and the heating plate 2 19 and the inclined guide surface 21 at the bottom of the inner wall of the groove 20 effectively prevent the asphalt mixture from accumulating on the heating plate 18 and the heating plate 2 19, ensuring the smooth operation of the heating plate 18 and the heating plate 2 19. When the ambient temperature is lower, the piston rod of the driving member 13 moves upward for a specific distance, and then the piston rod is reciprocated up and down. When the scattering bar 7 moves upward for this distance, the connecting rod 24 drives the heating plate 18 and the heating plate 2 19 to rotate upward, so that the distance between the heating plate 18 and the heating plate 2 19 and the inner wall of the heating chamber 6 is reduced. When the asphalt mixture falls from the heating chamber 6, the residence time of the asphalt mixture in the heating chamber 6 is increased, thereby effectively improving the heating effect of the asphalt mixture, so that it can well adapt to the weather environment with lower temperature; When the asphalt mixture falls from the heating plate 18 and the heating plate 2 19, the asphalt mixture is further dispersed under the further action of the dispersing piece 25 and the dividing strip 28, and the upward inclined surface 3 26 can improve the blocking ability of the asphalt mixture passing through the dispersing piece 25, further improving the dispersing effect of the dispersing piece 25 on the asphalt mixture; Finally, the asphalt mixture after the above dispersion and heating falls from the discharge port at the bottom of the heating element 5 and falls into the feed hopper of the paver, and then the paver can pave the asphalt mixture.

In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
