Description

Technical Field

[0001] This utility model relates to the field of asphalt recycling technology, and in particular to a waste asphalt recycling device. Background Technology

[0002] Waste asphalt, after crushing and screening, can be recycled for use in new road construction or repair projects, saving resources and reducing environmental pollution. Through hot or cold recycling technologies, waste asphalt can be recombine with new asphalt mixtures to form new materials with good performance for reuse, reducing usage costs. An existing patent (publication number: CN119189127A) discloses a device for recycling asphalt waste from highway pavements. This invention uses a drive mechanism and a first crushing mechanism to crush the asphalt waste fed into the inlet. The crushed asphalt fragments fall into a screening box, where they are further screened. Larger asphalt fragments undergo secondary crushing, achieving continuous crushing of asphalt waste and improving work efficiency. However, in practical applications, this device only uses one motor to provide power, which is transmitted through a second pulley and other transmission components. The transmission structure is relatively complex, and when a fault occurs, the relevant transmission structures need to be checked one by one, which is inconvenient for later maintenance. Therefore, we propose a waste asphalt recycling device. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a waste asphalt recycling device.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] Design a waste asphalt recycling device, including a box body with supporting legs. A feed chute and a discharge chute are connected to the upper and lower sides of the box body, respectively. A pair of opposing rotating crushing rollers are located below the feed chute. The crushing rollers are connected to the box body via a rotating shaft, which is driven by a servo motor. A screening structure is movably located below the crushing rollers. The screening structure includes a diversion track with screening mesh openings. A vibration mechanism is located between the diversion track and the bottom of the box body. A material collection shell is fixed to the bottom of the diversion track. A guide cylinder inserted into the discharge chute is connected to the bottom end of the material collection shell. A secondary processing mechanism is located below the end of the diversion track. The secondary processing mechanism includes a guide tray and a discharge tray. The crushing roller, driven by the servo motor, is located inside the guide tray.

[0006] In the above scheme, pulleys are installed on both the end of the rotating shaft and the output shaft of the servo motor, and a belt connects the pulleys.

[0007] In the above scheme, the diversion track is in the shape of an inverted V, and baffles are fixed on both sides of the diversion track.

[0008] In the above scheme, the vibration mechanism includes a support plate disposed inside the box, a vibration motor connected to a baffle is mounted on the support plate, and a buffer spring is also connected between the baffle and the support plate.

[0009] In the above scheme, the guide tube is covered with a buffer sleeve.

[0010] In the above scheme, the second crushing roller is connected to the housing via the second rotating shaft, and the second output shaft of the second servo motor and the second rotating shaft are both equipped with pulleys, and the pulleys are connected by a belt.

[0011] In the above scheme, the flow guide tray is tilted downward and connected to the discharge tray. The inner wall of the flow guide tray is covered with a grinding plate, and the two sides of the box are provided with discharge ports adapted to the discharge tray.

[0012] The advantages and beneficial effects of this utility model are as follows: By setting up a box body, feeding chute, crushing roller one, servo motor one, screening structure, collection shell, discharge chute, guide cylinder, crushing roller two, servo motor two, guide tray and discharge tray, the recycled waste asphalt is introduced into the box body through the feeding chute. The servo motor one provides power to make the crushing roller one rotate in opposite directions, crushing the asphalt blocks falling on the crushing roller one. The crushed asphalt blocks fall onto the diversion track, and are screened through the screening mesh to separate large and small asphalt blocks. The fully crushed small asphalt blocks pass through the screening mesh and enter the collection shell. The asphalt blocks are then discharged from the discharge chute through the guide tube, while the large asphalt blocks that are not fully crushed slide down the diversion track and fall into the guide tray. At the same time, the large asphalt blocks are further crushed by the second crushing roller. After processing, they are discharged outward through the discharge tray. Compared with the existing technology, by setting servo motor one and servo motor two to drive crushing roller one and crushing roller two respectively, the transmission structure is simplified, which facilitates later maintenance and improves practicality. By setting a vibration mechanism and using a vibration motor to vibrate the diversion track, the asphalt blocks are diverted, the processing speed of asphalt blocks is increased, and the work efficiency is effectively improved.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a waste asphalt recycling device, including a box 1 with support legs 2 installed. The upper and lower sides of the box 1 are respectively connected to a feeding trough 3 and a discharge trough 12. The support legs 2 are used to suspend the discharge trough 12 at the bottom of the box 1 so that a collection container can be placed below the box 1 to collect the processed waste asphalt. A pair of crushing rollers 4 rotating in opposite directions are provided below the feeding trough 3. The crushing rollers 4 are connected to the box 1 through a rotating shaft 5. The rotating shaft 5 is connected to a servo motor 6 for transmission.

[0022] Furthermore, pulleys 24 are installed at the end of shaft 5 and on the output shaft of servo motor 6, and belts are connected between pulleys 24. Servo motor 6 is mounted on the surface of housing 1 via a bracket. There are two sets of belts here. One set is the belt connecting the pulleys 24 installed on adjacent shafts 5. Its characteristic is that they are staggered so that the adjacent pulleys 24 rotate in opposite directions. The other set is the belt connecting the pulley 24 installed on the output shaft of servo motor 6 and the pulley 24 installed on one of the shafts 5. These belts are connected sequentially and are mainly used to transmit power. They not only achieve the purpose of transmitting power, but also enable adjacent crushing rollers 4 to rotate in opposite directions, causing asphalt blocks to gather in the gap between crushing rollers 4, so that the asphalt blocks can fully contact the crushing rollers 4, thereby enabling the asphalt blocks to be fully processed.

[0023] A screening structure is provided below the crushing roller 4. The screening structure includes a diversion track 7, on which screening mesh 8 is provided. The screening mesh 8 is used to screen asphalt blocks of different sizes.

[0024] Furthermore, the diversion track 7 is inverted V-shaped, allowing the asphalt blocks falling on the diversion track 7 to slide along the diversion track 7 under the action of gravity. Baffles 9 are fixed on both sides of the diversion track 7 to prevent the asphalt blocks from splashing outwards.

[0025] A vibration mechanism is provided between the diversion track 7 and the bottom of the box 1;

[0026] Furthermore, the vibration mechanism includes a support plate 13 installed on the inner wall of the bottom of the housing 1. A vibration motor 14 connected to the baffle 9 is installed on the support plate 13. The vibration motor 14 is used to make the diversion track 7 vibrate rapidly. A buffer spring 15 is also connected between the baffle 9 and the support plate 13. The buffer spring 15 is a rigid spring. In conjunction with the buffer spring 15, it can not only provide a certain support for the diversion track 7, but also buffer the vibration of the diversion track 7, so that the vibration effect is kept within a suitable range.

[0027] Specifically, by setting up a vibration mechanism and using a vibration motor 14 to vibrate the diversion track 7, the asphalt blocks are diverted, the speed of processing the asphalt blocks is increased, and the work efficiency is effectively improved.

[0028] The bottom of the diversion track 7 is fixed with a material collection shell 10. The bottom end of the material collection shell 10 is connected to a guide cylinder 11 that is inserted into the discharge trough 12. The material collection shell 10 and the guide cylinder 11 are used to construct a discharge channel so that the fully crushed asphalt blocks move toward the discharge trough 12 and prevent asphalt blocks from accumulating in the box 1.

[0029] Furthermore, the guide tube 11 is covered with a buffer sleeve; the buffer sleeve is made of rubber, which improves the wear resistance of the buffer sleeve and reduces the impact on the discharge chute 12, inhibits the guide tube 11 from being damaged due to long-term collision with the discharge chute 12, and extends the service life.

[0030] A secondary processing mechanism is provided below the end of the diversion track 7. The secondary processing mechanism includes a guide tray 16 and a discharge tray 17. The guide tray 16 is equipped with a crushing roller 19 driven by a servo motor 22.

[0031] Furthermore, the crushing roller 19 is connected to the housing 1 via the rotating shaft 20. Both the output shaft of the servo motor 22 and the rotating shaft 20 are equipped with pulleys 21, and a belt is connected between the pulleys 21. The servo motor 22 provides power to make the crushing roller 19 rotate, thereby crushing the large pieces of asphalt that fall into the guide tray 16.

[0032] Furthermore, the flow guide tray 16 is tilted downward and connected to the discharge tray 17. The inner wall of the flow guide tray 16 is covered with a grinding plate 18. In conjunction with the grinding plate 18, the crushing effect on large pieces of asphalt is enhanced. The two sides of the box body 1 are provided with discharge ports 23 that are adapted to the discharge tray 17 so that the asphalt after secondary processing can be discharged.

[0033] Specifically, the system comprises a housing 1, a feeding chute 3, a first crushing roller 4, a servo motor 6, a screening structure, a collection shell 10, a discharge chute 12, a guide cylinder 11, a second crushing roller 19, a second servo motor 22, a guide tray 16, and a discharge tray 17. Recycled waste asphalt is fed into the housing 1 through the feeding chute 3. The servo motor 6 provides power, causing the first crushing roller 4 to rotate in opposite directions, crushing the asphalt blocks that fall onto it. The crushed asphalt blocks fall onto the diversion track 7 and are then screened through the screening mesh 8 to separate large and small asphalt blocks. The fully crushed asphalt lumps enter the aggregate shell 10 through the screening mesh 8, and then are discharged from the discharge trough 12 through the guide tube 11. The asphalt lumps that are not fully crushed slide down the diversion track 7 and fall into the guide tray 16. At the same time, the crushing roller 19 further crushes the asphalt lumps. After processing, the asphalt lumps are discharged outward through the discharge tray 17. Compared with the prior art, by setting servo motor 6 and servo motor 22 to drive crushing roller 4 and crushing roller 19 respectively, the transmission structure is simplified, which facilitates later maintenance and improves practicality.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
