Detailed implementation mode

[0024] The following further non-restrictive detailed description of the technical solution of the present invention is made in conjunction with the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0025] Please refer to Figures 1-5 As shown, a discharge structure for an asphalt crushing and screening machine includes the main body 2 of the crushing and screening machine. A chute 4 is provided on the outer wall of the main body 2 of the crushing and screening machine, and a slider 26 is connected inside the chute 4. A sliding frame 5 is installed on the outer wall of the slider 26, and a connecting plate 6 is connected inside the sliding frame 5.

The connecting plate 7 is sleeved on the outer wall of the main body 2 of the crushing and screening machine, and the bottom of the connecting plate 7 is connected with a connecting ring 8. The bottom of the connecting ring 8 is connected with a rotating frame 9.

[0026] A support base 3 is installed on the outer wall of the main body 2 of the crushing and screening machine, and a base 14 is connected to the outer wall of the support base 3. A driving shaft 11 is installed on the top of the base 14. The top end of the driving shaft 11 is connected with a motor 10. A first installation groove 13 is provided on the outer wall of the driving shaft 11, and a second installation groove 15 is provided on the outer wall of the rotating frame 9. The outer wall of the driving shaft 11 and the outer wall of the rotating frame 9 are movably connected through the first installation groove 13 and the second installation groove 15 with a conveyor belt 12.

[0027] During operation, open the top cover 1, and pour the asphalt raw materials to be crushed into the interior of the crushing and screening machine main body 2 through the crushing and screening machine main body 2. The crushing and screening machine main body 2 processes the asphalt raw materials. After the asphalt raw materials are crushed, they are discharged downward through the discharge port 25. At the same time, start the motor 10 to drive the drive shaft 11 to rotate. The rotating drive shaft 11 drives the rotating frame 9 to rotate by means of the conveyor belt 12. Furthermore, after the crushed asphalt is rotated, it can play a role in dispersing it. Then start the vibration motors 16 on both sides of the bottom. The vibration motors 16 drive the vibration frame 18 to vibrate up and down, so that the asphalt raw materials fall downward onto the surface of the filter plate 19. The vibrating filter plate 19 allows the small-particle asphalt raw materials to fall downward through the filter holes 20. The asphalt raw materials with larger particles remain on the surface of the filter plate 19. The filter plate 19 can be disassembled to pour the large-particle asphalt raw materials on the surface of the filter plate 19 back into the crushing and screening machine main body 2 for re-crushing, thus completing the work.

[0028] In this embodiment, a receiving groove 24 is formed at the bottom of the rotating frame 9, and a receiving plate 17 is connected inside the receiving groove 24. The bottom of the receiving plate 17 is connected to a vibration frame 18, and a vibration motor 16 is installed at the bottom of the vibration frame 18. By inserting the receiving plate 17 into the receiving groove 24 and leaving a certain distance between the two, it is convenient to drive the vibration motor 16 so that the receiving plate 17 can move up and down inside the receiving groove 24, achieving the effect of vibrating the vibration frame 18 up and down.

[0029] In this embodiment, a cavity 23 is formed in the inner bottom wall of the vibration frame 18, and a filter plate 19 is arranged inside the cavity 23. A positioning groove 21 is formed in the inner top wall of the cavity 23, and a positioning block 22 that is identical in shape and size to the positioning groove 21 is installed at the top of the filter plate 19. The filter plate 19 is snap-connected to the bottom of the vibration frame 18 through the positioning groove 21 and the positioning block 22. By providing the positioning groove 21 and the positioning block 22, the filter plate 19 can be installed at the bottom of the vibration frame 18, facilitating the disassembly of the position of the filter plate 19.

[0030] In this embodiment, filter holes 20 are formed at the top of the filter plate 19, and the filter holes 20 penetrate to the bottom of the filter plate 19. A plurality of filter holes 20 are evenly distributed on the surface of the filter plate 19. By installing a vibration frame 18 at the bottom of the rotating frame 9 and installing a filter plate 19 inside the vibration frame 18, the two vibration motors 16 installed on the outer wall of the vibration frame 18 can vibrate the vibration frame 18 up and down, enabling the asphalt raw materials falling onto the surface of the filter plate 19 to be sieved again, realizing that the discharge structure of the asphalt crushing and screening machine can perform multiple sieving operations on the asphalt raw materials, solving the problems of simple structure and single functionality of general asphalt crushing and screening machines, and improving the adaptability of the discharge structure of the asphalt crushing and screening machine.

[0031] In this embodiment, grooves are provided at both the bottom of the connecting plate 7 and the top of the rotating frame 9. The bottom of the connecting plate 7 and the top of the rotating frame 9 are both movably connected with a connecting ring 8 through the grooves. The centers of the connecting plate 7, the connecting ring 8, and the rotating frame 9 coincide. The rotating frame 9 is rotationally connected to the bottom of the connecting plate 7 through the connecting ring 8. The provided connecting ring 8 facilitates the rotation of the rotating frame 9 at the bottom of the connecting plate 7, and the rotating frame 9 can play a supporting role.

[0032] In this embodiment, a fixing groove 28 is provided at the top of the connecting plate 6. A fixing block 27 whose shape and size are exactly the same as those of the fixing groove 28 is provided at the bottom of the sliding frame 5. The sliding frame 5 is fixedly connected to the connecting plate 6 through the fixing block 27 and the fixing groove 28. The sliding frame 5 is slidably connected to the outer wall of the crushing and screening machine main body 2 through a slider 26 and a chute 4. By providing the slider 26 and the chute 4, the position of the sliding frame 5 can be slid up and down. Sliding the sliding frame 5 downward facilitates the connection between the sliding frame 5 and the connecting plate 6. After the sliding frame 5 and the connecting plate 6 are disassembled, the overall discharge structure at the bottom of the crushing and screening machine main body 2 can be disassembled downward, which is convenient for use.

[0033] In this embodiment, a top cover 1 is installed at the top of the crushing and screening machine main body 2, and the center lines of the top cover 1 and the crushing and screening machine main body 2 coincide. By providing the top cover 1 covering the top of the crushing and screening machine main body 2, the top of the crushing and screening machine main body 2 can be installed and connected.

[0034] In this embodiment, a discharge port 25 is provided at the bottom of the crushing and screening machine main body 2, and the discharge port 25 is located at the top of the rotating frame 9. The center lines of the rotating frame 9 and the discharge port 25 coincide. By arranging the discharge port 25 at the top of the rotating frame 9, after the asphalt aggregates are crushed, they can fall downward through the discharge port 25 into the interior of the rotating frame 9.

[0035] In summary, for the discharge structure of this asphalt crushing and screening machine, when the rotating frame 9 rotates, the asphalt raw materials inside the crushing and screening machine main body 2 can fall downward through the discharge port 25 into the rotating frame 9 for rotational discharge, improving the working efficiency of the asphalt crushing and screening device for asphalt discharge. It solves the problem that general asphalt crushing and screening devices simply pour raw materials with different particle sizes into the device, crush them, and then screen them, and cannot fully crush the raw materials, resulting in possible blockage and difficulty in removal during the discharge of asphalt raw materials, reducing the working efficiency and practicality of the asphalt crushing and screening machine, and improving the efficiency of the discharge structure of this asphalt crushing and screening machine.
