The material leakage box 3 is used for feeding and continuously leaking the incoming materials into the main body 2 of the crushing device.
[0022] On one side of the main body 2 of the crushing device, a connecting device 5 is provided. The connecting device 5 is used to connect the crushing device and the pretreatment table 8. On one side of the connecting device 5, a pretreatment table 8 is fixedly installed. The pretreatment table 8 is used to process and crush larger objects and irregular asphalt blocks that are not easy to crush. A groove 25 is formed on the upper surface of the pretreatment table 8. The asphalt blocks to be pretreated can be placed in the groove 25. A second electric push rod 12 is fixedly installed on the side wall of the groove 25. The output end of the second electric push rod 12 penetrates the side wall of the groove 25 and is slidably connected thereto. The output end of the second electric push rod 12 is fixedly installed with a push plate 16. The push plate 16 is used to push away the pretreated asphalt blocks and make this part of the asphalt blocks pass through the main body 2 of the crushing device. Above the groove 25, a bracket 9 is provided. The bracket 9 is arranged in an inverted U shape. A first electric push rod 10 is fixedly installed on the upper surface of the bracket 9. The output end of the first electric push rod 10 penetrates the top wall of the bracket 9 and is slidably connected thereto. The output end of the first electric push rod 10 is provided with a pressing block assembly 11. The pressing block assembly 11 is used to crush the pretreated asphalt blocks.
[0023] Normal small asphalt blocks can be directly put into the hopper 3, and they will be crushed by the main body 2 of the crushing device. The crushed materials will flow out from the discharge port 4. When encountering larger and round asphalt blocks that are not easy to break, they can be placed on the pretreatment table 8. Then, the first electric push rod 10 is started. The first electric push rod 10 will drive the entire pressing block assembly 11 to press down and crush the asphalt blocks. After crushing, the pressing block assembly 11 is retracted. Then, the second electric push rod 12 is started. The second electric push rod 12 drives the push plate 16 to push away the pretreated crushed materials.
[0024] Embodiment 2
[0025] Please refer to Figure 2 - Figure 3 As shown in, on the basis of Embodiment 1, the pressing block assembly 11 includes a pressing block body 13, a screw 14 and a pressing head 15. The pressing block body 13 is fixedly installed at the output end of the second electric push rod 12. The movement of the output end of the second electric push rod 12 will drive the pressing block to move. The pressing head 15 is arranged on the lower surface of the pressing block body 13 and extends into the pressing block body 13. The lower end of the pressing head 15 is tapered. A threaded hole is formed at the upper end of the pressing head. The screw 14 is arranged on the upper surface of the pressing block body 13. One end of the screw 14 extends into the pressing block body 13 and the pressing head 15 and is threadedly connected to the pressing head 15. The screw 14 is threadedly connected to the threaded hole. An inclined plate 6 is arranged on the connecting device 5. After the push plate 16 pushes away the pretreated crushed materials, the crushed materials will be pushed onto the inclined plate 6. One end of the inclined plate 6 is arranged above the hopper 3. In this way, the crushed materials will flow into the hopper 3 along the inclined plate 6.
[0026] On one side of the pretreatment table 8, a rectangular groove 21 is provided. A third electric push rod 20 is arranged in the rectangular groove 21. The third electric push rod 20 is fixedly installed at the top of the rectangular groove 21, and the output end of the third electric push rod 20 penetrates through the top wall of the rectangular groove 21 and extends into the sliding groove. A sliding groove is provided at the bottom of the groove 25. A telescopic baffle 19 is slidably connected in the sliding groove. The retractable plate can lift and lower in the sliding groove. The output end of the third electric push rod 20 extends into the sliding groove and is fixedly connected to the lower surface of the telescopic baffle 19. The third electric push rod 20 is used to control the lifting and lowering of the retractable plate. When encountering a circular asphalt block, it will roll in the groove 25, and the setting of the retractable plate blocks the possible rolling directions, so that it will not roll towards the inclined plate 6 during the crushing process.
[0027] When encountering a spherical asphalt block, it will roll in the groove. At this time, start the third electric push rod to lift the telescopic plate so that it can block the spherical asphalt block and make it be crushed stably. After the push plate pushes away the pretreated crushed material, the crushed material will be pushed onto the inclined plate. One end of the inclined plate is arranged above the material leakage box. In this way, the crushed material will flow into the material leakage box along the inclined plate.
[0028] Embodiment III
[0029] Please refer to Figure 3 - Figure 4 , on the basis of Embodiment II, a plurality of cylindrical grooves are provided at the bottom of the groove. A telescopic device is arranged in the cylindrical groove. The telescopic device is used to prevent the pointed end of the pressing head from colliding with the pretreatment table due to too much force when the pressing head presses down. In this way, once a collision occurs, the pressing head will extend into the cylindrical groove. The telescopic device includes a telescopic column and a spring. When the pressing head extends into the cylindrical groove, the crushed material will also enter the cylindrical groove. Then when the pressing plate is lifted, under the action of the spring, the crushed material will pop out of the telescopic column and fall into the groove. The telescopic column is slidably connected to the cylindrical groove. The spring is arranged in the telescopic column. An inclined surface is provided on the upper surface of the telescopic column. The setting of the inclined surface makes the telescopic column pass through when the push plate is pushing the material, so that it will contact the inclined surface and press the telescopic column into the cylindrical groove.
[0030] In actual use, normal small asphalt blocks can be directly placed into the channel leakage box and will be crushed by the main body of the crushing device. The crushed materials will flow out from the discharge port. When encountering large, round asphalt blocks that are difficult to crush, they can be placed on the pretreatment table, and then the first electric push rod is started. The first electric push rod will drive the entire pressing block assembly to press down and crush the asphalt block. After crushing, the pressing block assembly is retracted, and then the second electric push rod is started. The second electric push rod drives the push plate to push away the pretreated crushed materials. When encountering spherical asphalt blocks, they will roll in the groove. At this time, the third electric push rod is started to lift the telescopic plate so that it can block the spherical asphalt block and make it be crushed stably. After the push plate pushes away the pretreated crushed materials, the crushed materials will be pushed onto the inclined plate. One end of the inclined plate is arranged above the leakage box. In this way, the crushed materials will flow into the leakage box along the inclined plate. During the process of the push plate pushing the materials, the push plate will contact the inclined surface and under the action of the inclined surface, the telescopic column will be pressed into the columnar groove. In this way, the materials can be smoothly pushed onto the inclined plate.
[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
