Description

Technical Field

[0001] The invention relates to the field of operation and collection technology, and in particular to a waste operation and collection device for cold road regeneration construction. Background Art

[0002] The traditional asphalt concrete pavement maintenance method is to cold mill the old pavement and then repave it with new cement-stabilized gravel materials or asphalt mixtures. The asphalt pavement cold recycling technology makes 100% use of the old asphalt mixture. Only adhesives and some new materials are added during recycling and maintenance. The cold recycled material can be used as the lower layer or base layer in the new highway structure. It is first repaved by a paver and re-compacted by a roller to form a new pavement base layer. Finally, the pavement asphalt layer is paved on the new base layer. This technology can realize the recycling of old asphalt pavement materials, while reducing electricity consumption, carbon dioxide emissions, the amount of new materials added, transportation volume, and construction period, significantly improving the durability and service life of the pavement structure.

[0003] In the existing technology, the cold recycling construction of pavement is to cut and crush the old asphalt pavement while adding and mixing cement or foamed asphalt. The cold recycled mixture that meets certain road performance is then transferred to the paver hopper. Finally, the paver re-paves the recycled material in the pavement structure and the roller completes the compaction. The core of this process is the W380CR cold recycling machine. However, the current cold recycling machine may not have uniformity during the mixing process, making it difficult to rework and re-mix, which can easily lead to uneven adhesion of the new base pavement, thus affecting the pavement paving quality.

[0004] In addition, because cement or foamed asphalt is added as a binder to the cut pavement material, a layer of adhesive is easily accumulated on the surface of the conveyor after mixing and continuous transportation, which increases the idling load of the conveyor, thereby reducing the transportation volume of the cold recycled mixture and increasing energy consumption.

[0005] In view of this, the present invention proposes a waste collection device for cold pavement regeneration construction to make up for and improve the shortcomings of the prior art. Summary of the invention

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. During transportation, by setting up an auxiliary uniform feeding mechanism and using a diverter plate and a feeding tray in combination, the mixed material can be assisted to be evenly mixed again horizontally and vertically during the feeding process to prevent the unevenness after mixing, thereby improving the road paving quality.

[0018] Among them, since the diverter plate is in an inverted V shape and the bend is arranged near one side of the transmission frame, and the diverter plate is specifically composed of a vertical plate with a bend at the top connected to an inclined plate, when the mixture contacts the connection between the vertical plate and the inclined plate of the diverter plate, it will be diverted to both sides, and the diverted flows are interspersed and converged into the discharge tray, and then the telescopic rod is used to perform telescopic movement, pulling the discharge tray to rotate back and forth, so that the mixture inside it is cut off horizontally for discharge, so that all the mixture in the range from cutting to paving position can be evenly mixed horizontally and vertically, thereby effectively eliminating the variability of the original pavement material.

[0019] 2. Through the setting of the conveying weight reduction mechanism, during the conveying process, since the bumps on the outer surface of the conveyor belt are set in the shape of a quarter elliptical sphere and the lateral distribution of the bumps can effectively increase the surface resistance of the conveyor belt, which is conducive to the transmission of more cold recycled mixtures, and is less likely to cause material backflow, thereby improving the transmission efficiency. At the same time, cement or foamed asphalt adhesives can be collected through the collection box for recycling to avoid waste. After the surface adhesive of the conveyor belt is collected, the idling weight of the conveyor belt can be reduced to increase the transportation volume of the mixture, thereby saving output energy consumption.

[0020] 3. By setting the outer diameter of the first gear larger than the outer diameter of the second gear, the rotation speed of the roller can be faster than the conveying speed of the conveyor belt. Combined with the symmetrical spiral distribution of bristles on the roller, the conveyor belt and the bump passing through the roller are not only brushed by the bristles, but also brushed in the forward and reverse diagonal directions at least twice. The two sides of the bristles are connected end to end, which ensures the continuity of the reciprocating brushing. The increased speed rotation combined with the reciprocating diagonal brushing can effectively remove the adhesive in the dead corners of the bump edges, thereby reducing the load on the conveyor belt surface.

[0040] The support rod 412 is located at the center of the unloading tray 45 .

[0041] The diverter plate 410 is composed of a vertical plate with a bent top connected to an inclined plate, and the chamfer of the diverter plate 410 avoids affecting the concentration of the mixed material after diversion.

[0042] The effects achieved by this embodiment are as follows: In the prior art, the cold regeneration machine may have insufficient uniformity during the mixing process, which makes it difficult to rework and re-mix, and easily leads to uneven adhesion of the new base road surface, thereby affecting the quality of road paving. Compared with the prior art, through the implementation of this embodiment, an auxiliary uniform feeding mechanism 4 is set up, which can adopt the coordinated use of the diverter plate 410 and the feeding tray 45, which can assist in mixing the mixed material evenly again horizontally and vertically during the feeding process to prevent the uneven uniformity after mixing, thereby improving the road paving quality.

[0043] For further examples, please refer to Figures 1 to 3 , Figures 7 to 10 As shown, the conveying weight reduction mechanism 5 includes a collecting box 52 fixedly connected to the bottom of the transmission frame 2, the bottom of the collecting box 52 is fixedly connected to a discharge pipe 51, the top edge of the collecting box 52 is also fixedly connected to the outer wall of the protective cover 43, the middle of the collecting box 52 is rotatably connected to a rotating shaft 59, one side of the rotating shaft 59 is rotatably connected to the inner wall of the collecting box 52, the other side of the rotating shaft 59 rotates through the outer wall of the collecting box 52 and is fixedly connected to a second gear 54, the outer wall of the second gear 54 is meshedly connected to the first gear 53, and the center of the first gear 53 is fixedly connected to the axis of the pulley 3.

[0044] The conveying weight reduction mechanism 5 also includes a transmission belt 55 rotatably connected to the outer wall of the pulley 3, and the outer wall of the transmission belt 55 is fixedly connected with a plurality of protrusions 56 at equal intervals. The outer wall of the rotating shaft 59 is fixedly connected with a roller 57, and the outer wall of the roller 57 is fixedly connected with a plurality of bristles 58, and the outer walls of the plurality of bristles 58 are in contact with the outer walls of the protrusions 56.

[0045] The protrusions 56 are in the shape of a quarter ellipsoid and are distributed laterally on the outer surface of the conveyor belt 55 .

[0046] The bristles 58 are symmetrically distributed in spirals on both sides of the roller 57, and the two sides are connected end to end.

[0047] The outer diameter of the first gear 53 is greater than the outer diameter of the second gear 54 .

[0048] The second gear 54 is used to speed up the roller 57, and the symmetrical spiral distribution of the bristles 58 facilitates the oblique reciprocating brushing of the bristles 58.

[0049] The effects achieved by this embodiment are as follows: In the prior art, a layer of adhesive is easily accumulated on the surface of the conveying device after continuous transportation after mixing, which increases the idling weight of the conveying device, thereby reducing the transportation volume of the cold recycled mixture and increasing energy consumption. Compared with the prior art, through the implementation of this embodiment, the conveying weight reduction mechanism 5 is set to enable the plurality of protrusions 56 distributed laterally on the outer surface of the conveyor belt 55 to be set in a quarter ellipsoidal shape during the conveying process, which can effectively increase the surface resistance of the conveyor belt 55, is conducive to the transportation of more cold recycled mixture, is less likely to cause material backflow, and improves the transmission efficiency. At the same time, the cement or foam asphalt adhesive can be collected by the collection box 52 for recycling to avoid waste. After the adhesive on the surface of the conveyor belt 55 is collected, the idling weight of the conveyor belt 55 can be reduced to increase the transportation volume of the mixture.

[0050] The complete usage steps and working principle of the above embodiment are as follows: In the initial state: the telescopic rod 44 is on the connecting rod 47 and is located on the side close to the discharge tray 45, a pair of discharge ports 46 are parallel to the collection box 52, and the pulley 3 and the conveyor belt 55 are in a stationary state.

[0051] During use, when the cold recycled mixture that has been cut and mixed by the machine body 1 is transported to the transmission frame 2, the operator starts the driving device to rotate the conveyor belt 55 around the pulley 3, and the conveyor belt 55 drives the mixture to be transported in the direction of the protective cover 43. When the mixture enters the protective cover 43, it first passes through the diverter plate 410. Since the diverter plate 410 is in an inverted V shape and the bend is arranged close to one side of the transmission frame 2, and the diverter plate 410 is specifically composed of a vertical plate with a bend at the top connected to an inclined plate, when the mixture contacts the connection between the vertical plate and the inclined plate of the diverter plate 410, it will be diverted to both sides. The mixture close to the vertical plate will quickly slide down along the inner wall of the protective cover 43 and directly fall into the discharge tray 45, and then pass through the discharge tray 45. The mixture is discharged from the outlet 46 into the hopper of the paver, while the mixture on the side of the inclined plate of the diverter plate 410 slides along the inclined plate to the side away from the transmission frame 2 until it reaches the long rod 411. Under the action of gravity and the rotation acceleration of the long rod 411, the mixture can slide down smoothly along the inner wall of the other side of the protective cover 43 without being blocked. At this time, the mixture falls into the lower material tray 45 with a certain delay compared to the first batch of mixture diverted to the vertical plate. Therefore, the first batch of mixture diverted to the side of the inclined plate of the diverter plate 410 will be gathered in the lower material tray 45 together with the second batch of mixture diverted to the side of the vertical plate. In this way, the continuous diversion, interlacing, convergence and mixing can achieve the effect of longitudinal mixing.

[0052] Furthermore, when the pulley 3 rotates for transmission, it can also drive the turntable 41 to rotate synchronously, thereby causing the first slide post 48 eccentrically fixed on the turntable 41 to rotate synchronously, and then the top of the slide slot rod 42 is driven to swing back and forth continuously through the first slide post 48. Under the action of the lever principle, the bottom of the slide slot rod 42 will swing in the opposite direction synchronously, and then the slide slot rod 42 drives the second slide post 413 to slide continuously, and then through the limiting effect of the slide rail 49, the telescopic rod 44 fixed to the second slide post 413 performs a reciprocating telescopic motion. When the telescopic rod 44 performs the telescopic motion, the connecting rod 47 pulls the discharge tray 45 to rotate back and forth. At this time, the telescopic rod 44 on the connecting rod 47 will also change from the initial state to a side position away from the discharge tray 45. When the discharge tray 45 is driven by the connecting rod 47 to rotate back and forth, the pair of discharge ports 46 at the bottom will also make reciprocating rotation motion accordingly, and then the mixture inside the discharge tray 45 is cut off horizontally for discharge, thereby achieving a horizontal mixing effect of the mixture. Combined with the above-mentioned vertical mixing effect, it can assist in mixing the mixed mixture evenly again horizontally and vertically during the discharge process to prevent uneven mixing, thereby improving the road paving quality.

[0053] Please refer to the above working process Figures 1 to 8 .

[0054] Furthermore, when the pulley 3 rotates for transmission, it can also drive the first gear 53 to rotate synchronously. Since the outer diameter of the first gear 53 is larger than the outer diameter of the second gear 54, the rotation speed of the second gear 54 will be faster than the first gear 53, so the second gear 54 can drive the roller 57 to rotate quickly, and the rotation speed of the roller 57 is also faster than the transmission belt 55. During transportation, the bumps 56 are in the shape of a quarter ellipsoid and are laterally distributed on the outer surface of the transmission belt 55, which can effectively increase the surface resistance of the transmission belt 55, which is conducive to the transmission of more cold recycled mixed materials, and is not prone to material backflow, thereby improving the transmission efficiency. However, due to The cement or foamed asphalt adhesive mixed in the mixture is easy to adhere to the conveyor belt 55 and the bump 56. Therefore, the bristles 58 are arranged on the roller 57, and the bristles 58 are symmetrically spirally distributed on both sides of the roller 57, so that the conveyor belt 55 and the bump 56 passing through the roller 57 will be brushed by the bristles 58 at least twice in the forward and reverse directions. The two sides of the bristles 58 are connected end to end, which ensures the continuity of the reciprocating brushing and can effectively remove the adhesive in the dead corner of the edge of the bump 56, thereby reducing the extra weight caused by the adhesive on the conveyor belt 55, so as to increase the transportation volume of the mixture, and finally the adhesive is collected by the collection box 52 for recycling.
