[0023] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0024] like Figures 1 to 4 As shown, an asphalt regeneration and crushing device includes a frame 11 and a driving motor 12 fixedly arranged on the frame 11, a first collecting trough 13, a slide rail 15 and a crushing bin 21, a driving shaft 221 and a driven shaft 222 are rotatably arranged on the crushing bin 21, a crushing roller 24 is fixedly arranged on the driving shaft 221 and the driven shaft 222, the driving shaft 221 is fixedly connected to the output end of the driving motor 12, the driving shaft 221 and the driven shaft 222 are connected by gear transmission, a screening bucket 31 is slidably arranged on the slide rail 15, the driving shaft 221 and the driven shaft 222 are transmission-connected to the screening bucket 31, and the first collecting trough 13 is located below the screening bucket 31.
[0025] In this embodiment, after the drive motor 12 is started, the material is put into the crushing bin 21, the material is squeezed and crushed into small particles by the crushing roller 24, and rolls into the screening bucket 31 through the drop plate 25. The driving shaft 221 and the driven shaft 222 are connected to the slider 311 through the first spiral groove 231, driving the screening bucket 31 to move away from the drive motor 12, and the tension spring 16 accumulates force; the initial position of the slider 311 is located at the first intersection of the first spiral groove 231 and the second spiral groove 232. When the screening bucket 31 moves to the extreme position, that is, the slider 311 slides to the second intersection of the first spiral groove 231 and the second spiral groove 232, the slider 311 slides in the second spiral groove 232, and the tension spring 16 pulls the screening bucket 31 to quickly approach the drive motor 1 2, so that the screening bucket 31 is quickly reset. In the process of the screening bucket 31 moving away from and approaching the driving motor 12, the material rolls in the screening bucket 31, so that small particles of material pass through the screening holes 313 and fall into the first collecting tank 13, while large particles of material are retained. In the resetting process, the pushing plate 312 pushes the large particles of material to move in the direction close to the second collecting tank 14. When the screening bucket 31 moves to the initial position, affected by inertia, the large particles of material roll relative to the screening bucket 31 in the direction of the second collecting tank 14. Finally, the small particles of material fall into the first collecting tank 13, and the large particles of material fall into the second collecting tank 14, thereby completing the automatic screening of the materials, improving the convenience of screening the crushed asphalt concrete fragments, saving time and effort, improving the convenience of use, and improving the crushing quality.
[0026] like Figures 2 to 4As shown, the driving shaft 221 and the driven shaft 222 are both provided with a first spiral groove 231 and a second spiral groove 232, the first spiral groove 231 and the second spiral groove 232 are connected end to end to form a driving groove, the driving grooves are symmetrically arranged on the driving shaft 221 and the driven shaft 222, a slider 311 is arranged on the screening bucket 31 corresponding to the driving groove, and the driving shaft 221 and the driven shaft 222 are transmission-connected to the slider 311 via the driving groove. In this embodiment, the first spiral groove 231 and the second spiral groove 232 have the same pitch, different numbers of turns, and opposite rotation directions. The number of turns of the first spiral groove 231 is 0.8 turns, and the number of turns of the second spiral groove 232 is 0.2 turns. The first spiral groove 231 is used to push the screening bucket 31 to move through the slider 311, and the second spiral groove 232 is used to guide the slider 311, so that when the slider 311 is reset, it can be located at the first intersection of the first spiral groove 231 and the second spiral groove 232, and be pushed by the first spiral groove 231 again. When the slider 311 is located in the first spiral groove 231, the tension spring 16 cannot pull the screening bucket 31 to reset through the second mounting seat 315. The rotation of the driving shaft 221 and the driven shaft 222 can push the slider 311 through the first spiral groove 231, thereby pushing the screening bucket 31 to move. When the slider 311 is located in the second spiral groove 232, the tension spring 16 can pull the screening bucket 31 to quickly reset through the second mounting seat 315.
[0027] like Figure 2 As shown, the frame 11 is fixedly provided with a first mounting seat 111, and the screening bucket 31 is correspondingly provided with a second mounting seat 315, and the first mounting seat 111 and the second mounting seat 315 are fixedly connected by a tension spring 16. In this embodiment, in order to enable the material to be fully screened in the screening bucket 31, the screening bucket 31 is horizontally arranged, and the material will not spontaneously roll toward the second collecting tank 14 after falling into the screening bucket 31, so the first spiral groove 231 and the second spiral groove 232 with different turns and the same pitch are arranged, and the tension spring 16 is used to pull the screening bucket 31 to reset when the slider 311 is located in the second spiral groove 232, so that the screening bucket 31 performs reciprocating motion to screen the material, and the reset speed is faster, thereby driving the large particle material in the screening bucket 31 to roll toward the second collecting tank 14.
[0028] like Figure 1 and Figure 2 As shown, the frame 11 is fixedly provided with a second collecting trough 14 on the same horizontal plane as the first collecting trough 13, and a guide plate 32 is fixedly provided at one end of the screening hopper 31, and the guide plate 32 is located above the second collecting trough 14. In this embodiment, since the screening hopper 31 performs reciprocating motion, the guide plate 32 is provided to guide the large particle materials to fall into the second collecting trough 14 smoothly.
[0029] like Figures 1 to 3As shown, a reinforcing plate 316 is fixedly provided on the inner side of the screening bucket 31 away from the guide plate 32. In this embodiment, the reinforcing plate 316 is provided on one side of the connection position between the screening bucket 31 and the driving shaft 221 and the driven shaft 222 to improve the structural strength.
[0030] like Figure 1 and Figure 2 As shown, a push plate 312 is fixedly provided on the screening bucket 31 between the reinforcing plate 316 and the guide plate 32, and a screening hole 313 is provided on the push plate 312. In this embodiment, a plurality of right-angled triangular prisms are provided on the upper surface of the push plate 312, and the right-angled sides of the right-angled triangular prisms face the second collecting tank 14, so that when the large-size material falls on the push plate 312, when the push plate 312 moves away from the second collecting tank 14, the large-size material rolls relative to the push plate 312, and when the push plate 312 moves toward the second collecting tank 14, the large-size material moves toward the second collecting tank 14 together with the push plate 312.
[0031] like Figure 2 As shown, a drop plate 25 is provided on the crushing bin 21 below the crushing roller 24. In this embodiment, the drop plate 25 is used to guide the crushed material to fall on the side of the push plate 312 away from the second collecting tank 14, so that the small particles can be fully screened and prevent the small particles from falling directly into the second collecting tank 14 when the push plate 312 moves toward the second collecting tank 14.
[0032] like Figure 3 As shown, the drop plate 25 is hinged with the crushing bin 21, a support rod 251 is fixedly provided on the drop plate 25, a corrugated plate 314 is fixedly provided on the screening bucket 31, and the support rod 251 is slidably provided on the corrugated plate 314. In this embodiment, when the screening bucket 31 is reciprocating, the corrugated plate 314 moves synchronously with the screening bucket 31, and the corrugated plate 314 pushes the end of the drop plate 25 away from the second collecting trough 14 through the support rod 251 to shake up and down around the hinged position of the drop plate 25 and the crushing bin 21, so that the material falling on the drop plate 25 can fully and quickly fall into the screening bucket 31.
[0033] When implementing:
[0034] After the drive motor 12 is started, the material is put into the crushing bin 21, and the material is squeezed and crushed into small particles by the crushing roller 24, and rolls into the screening bucket 31 through the drop plate 25. The driving shaft 221 and the driven shaft 222 are connected to the slider 311 through the first spiral groove 231, and the slider 311 pushes the screening bucket 31 to move away from the second collecting tank 14. After the material falls into the screening bucket 31, the small particles fall into the first collecting tank 13 through the screening hole 313, while the large particles are retained. When the screening bucket 31 moves to the limit position, that is, the slider 311 slides to the first spiral groove 23 1 and the second intersecting position of the second spiral groove 232, the slider 311 slides in the second spiral groove 232, and the tension spring 16 pulls the screening bucket 31 to quickly move toward the direction close to the drive motor 12, so that the screening bucket 31 is quickly reset. During the resetting process, the push plate 312 pushes the large particle material to move toward the direction close to the second collecting tank 14. When the screening bucket 31 moves to the initial position, affected by inertia, the large particle material rolls relative to the screening bucket 31 toward the direction of the second collecting tank 14, and finally the small particle material falls into the first collecting tank 13, and the large particle material falls into the second collecting tank 14, completing the automatic screening of the material.
[0035] During the reciprocating motion of the screening bucket 31, the corrugated plate 314 on the screening bucket 31 pushes the end of the drop plate 25 away from the second collecting trough 14 through the support rod 251 and shakes up and down around the hinge position of the drop plate 25 and the crushing bin 21, so that the material falling on the drop plate 25 can fall into the screening bucket 31 fully and quickly.
[0036] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any technician familiar with the field can make many possible changes and modifications to the technical solution of the utility model by using the above-mentioned technical content without departing from the scope of the technical solution of the utility model, or modify it into an equivalent embodiment of equivalent changes. Therefore, any changes, modifications, equivalent changes and modifications made to the above embodiments based on the technology of the utility model without departing from the content of the technical solution of the utility model shall fall within the protection scope of the technical solution of the utility model.
