It is mainly used in stress absorption layers and surface layers in road structures. During the production of rubber asphalt, the waste rubber raw materials need to be sheared into suitable fine particles so that they can fully react when mixed with base asphalt.

[0003] The existing utility model with authorization announcement number CN220146420U discloses a raw material crushing device for rubber processing, including a crushing shell, both sides of the inside of the crushing shell are rotatably connected to rotating rollers, one end of the two rotating rollers passes through the crushing shell and is fixedly connected to connecting columns, and the surfaces of the two connecting columns are fixedly installed with linkage gears, and the other end of one of the rotating rollers is fixedly connected to the output end of the first motor.

[0024] See also Figure 1-4 A rubber raw material processing mechanism for producing rubber asphalt includes a housing 1, a screening mechanism 2 is provided inside the housing 1, and a dust removal mechanism 3 is provided on the left side of the housing 1;

[0025] The screening mechanism 2 includes a discharge port 201, which is opened on the left side of the shell 1. Two crushing rollers 202 are rotatably connected to the inside of the shell 1. The left end of each crushing roller 202 is fixedly connected to a forward and reverse motor 5. The upper surface of the shell 1 is fixedly connected to a feed pipe 6. The two forward and reverse motors 5 respectively drive the two crushing rollers 202 to rotate in opposite directions, thereby providing power for the crushing rollers 202 to increase the crushing effect. At the same time, the feed pipe 6 can increase the convenience of adding raw materials to the shell 1.

[0026] The inner wall of the shell 1 is fixedly connected with a material guide plate 203, and a rubber filter screen 204 is arranged inside the shell 1. The inner wall of the shell 1 is fixedly connected with an auxiliary block 205, and the interior of the auxiliary block 205 is slidably connected with a reset block 206. The back of the reset block 206 is fixedly connected to the front of the rubber filter screen 204, and the inner wall of the auxiliary block 205 is fixedly connected with two reset springs 4. The end of each reset spring 4 close to the reset block 206 is fixedly connected to the front of the reset block 206. The reset block 206 is continuously pushed to move by the telescopic force of the reset spring 4 itself, so that the reset block 206 can achieve the reset ability, thereby improving the effect of vibrating the rubber filter screen 204.

[0027] The interior of the shell 1 is slidingly connected to a collection box 207 and a moving block 208, and the bottom surface of the collection box 207 is fixedly connected to a sliding block 9, which is slidingly connected to the interior of the shell 1. The sliding block 9 can move simultaneously with the collection box 207, and relies on the friction generated by itself on the shell 1 during the movement to improve the stability of the collection box 207 during movement, thereby increasing the stability of the device.

[0028] The front of the moving block 208 is fixedly connected to the back of the rubber filter 204, and two fixed blocks 209 are fixedly connected to the back of the outer shell 1. The fixed blocks 209 and the outside of the servo motor 211 are jointly covered with a protective shell 10. The front of the protective shell 10 is fixedly connected to the back of the outer shell 1. The protective shell 10 can provide a protective effect for the fixed block 209 and the servo motor 211 to avoid injuries to people when they are not paying attention. At the same time, it can also prevent dust from entering the inside of the servo motor 211, thereby increasing the durability of the device.

[0029] The two fixed blocks 209 are internally connected to a cam 210 for common rotation. The top of the cam 210 is fixedly connected to a servo motor 211. The outer surface of the cam 210 is sleeved with an auxiliary bearing 11, which is embedded in one of the fixed blocks 209. The auxiliary bearing 11 can effectively reduce the friction generated by the cam 210 during rotation, making the cam 210 more sensitive during rotation. It can also reduce the wear of the cam 210 and increase the service life of the cam 210.

[0030] The dust removal mechanism 3 includes an auxiliary box 301, the right side of the auxiliary box 301 is fixedly connected to the left side of the outer shell 1, the interior of the auxiliary box 301 is slidably connected to the dust storage box 302, the interior of the dust storage box 302 is clamped with a dust filter plate 303, the bottom surface of the auxiliary box 301 is fixedly connected to the air pump 304, the upper surface of the auxiliary box 301 is fixedly connected to the exhaust pipe 305, the right end of the exhaust pipe 305 is fixedly connected to the left side of the outer shell 1, and two groups of support legs 7 are fixedly connected to the bottom surface of the outer shell 1. The outer surface of each group of support legs 7 is fixedly connected to a firm block 8. The support legs 7 can increase the height of the outer shell 1 and increase the moisture-proof ability of the outer shell 1. At the same time, the firm block 8 can increase the contact area between the support legs 7 and the ground, so that the support legs 7 are more stable when supporting.

[0031] The working principle of the present invention is as follows: when in use, firstly connect the servo motor 211, the air pump 304 and the forward and reverse motor 5 to the power supply, and load the rubber raw material into the shell 1 through the feed pipe 6, then start the forward and reverse motor 5, and use the power generated by the forward and reverse motor 5 to drive the two crushing rollers 202 to move in opposite directions, thereby crushing the raw material, and the crushed raw material will fall to the upper surface of the guide plate 203, and the slope of the guide plate 203 will cause the rubber particles to continue to roll downward, and then fall to the left side of the rubber filter 204, at this time, the servo motor 211 will drive the cam 210 to rotate, and then the cam 210 will intermittently push the moving block 208 to move, thereby moving the rubber filter 204 and the reset block 206, at this time the reset spring 4 will be compressed due to the pressure, and when the pressure disappears, it will push the reset block 206 and the rubber filter 204 to reset, thereby causing them to shake continuously. , and screen the rubber particles. Qualified rubber particles will fall into the collection box 207, and unqualified particle raw materials will continue to move through the slope of the rubber filter 204 until they are removed from the discharge port 201, thereby realizing the ability to screen the rubber particles and effectively improving the quality of the processed rubber particles. When dust removal is required, the vacuum pump 304 is started, and the vacuum pump 304 is used to extract the air in the auxiliary box 301 and make it in a negative pressure state. At this time, due to the different pressures, the exhaust pipe 305 will continue to extract the air mixed with dust in the shell 1, and transmit the air to the auxiliary box 301, and then filter the dust in the air through the dust filter plate 303, so that the dust remains in the dust storage box 302. The filtered air can be discharged along with the vacuum pump 304, thereby realizing the dust removal ability and preventing the operator from inhaling a large amount of dust during work, thereby effectively increasing the practicality of the device.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
