Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a grinding machine for regenerated asphalt raw materials. Background Art

[0002] The regeneration of asphalt is the reverse process of aging. Usually, regeneration agents can be added, such as corn oil, lubricating oil, etc. After adding the regeneration agent, the relative content of asphaltene is reduced, and the solubility of soft asphalt to asphaltene is increased, the compatibility of asphalt is improved, and the penetration and ductility of asphalt are increased, so that it can be restored to or close to its original performance.

[0003] After searching, Chinese patent CN220444053U was found and announced an asphalt raw material grinder. Through the cooperation of the second motor, the second connecting rod and the cam, the extension block can be driven to rotate, so as to drive the baffle to rotate synchronously to realize the opening of the bottom port of the feeding port, and realize the transportation of the asphalt raw material. With the help of the rotation of the cam and the action of the coil spring, the baffle can block the bottom port of the feeding port to the left and suspend the feeding. In this way, intermittent feeding to the feed port is realized to avoid the accumulation of asphalt raw materials due to continuous transportation. It can be seen that this patent achieves the avoidance of the accumulation of asphalt raw materials and reduces the burden of grinding. As a grinder, it is necessary to continuously extrude and refine the regenerated asphalt raw materials until the regenerated asphalt raw materials become small particles. However, this patent does not realize the function of refined grinding. In order to improve the grinding effect of raw asphalt raw materials, a regenerated asphalt raw material grinder is proposed.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 and Figure 3 A recycled asphalt raw material grinding machine includes a base plate 1, a support rod 2 is fixedly installed on the top of the base plate 1, a grinding seat 3 is fixedly installed on the top of the support rod 2, a support frame 4 is fixedly installed on the top of the base plate 1 and located on the outside of the grinding seat 3, a vertical rod 5 is fixedly installed on the top of the support frame 4, a mounting plate 6 is slidably connected to the outer surface of the vertical rod 5, the mounting plate 6 moves up and down on the outer surface of the vertical rod 5, and a stopper 8 corresponding to the mounting plate 6 is fixedly installed on the top of the vertical rod 5, which tries to avoid the mounting plate 6 from moving out of the vertical rod 5 and plays a limiting role.

[0021] See also Figure 2 and Figure 4 An extrusion and torsion assembly 7 for grinding the regenerated asphalt raw material is arranged on the grinding seat 3, the support frame 4 and the mounting plate 6. The extrusion and torsion assembly 7 includes a servo motor 71, a threaded column 72, a movable cylinder 73, a grinding head 74, a groove 75 and a grinding groove 76. The servo motor 71 is fixedly mounted on the top of the mounting plate 6, and the threaded column 72 is fixedly mounted on the output shaft of the servo motor 71. When the servo motor 71 is started, the threaded column 72 rotates to gradually grind the regenerated asphalt raw material. The threaded column 72 is rotatably connected to the mounting plate 6, and the threaded column 72 is threadedly connected to the top wall of the support frame 4. Under the threaded connection, the servo motor 71 and the mounting plate 6 can move up and down, and the movable cylinder 73 is fixedly mounted at the tail of the threaded column 72.

[0022] Moreover, the grinding head 74 is fixedly installed on the inner top wall of the movable cylinder 73. The threaded column 72 is threadedly connected to the top wall of the support frame 4, which not only allows the movable cylinder 73 and the grinding head 74 to rotate but also enables them to move up and down. The groove 75 is formed at the top of the grinding seat 3, and the movable cylinder 73 is inserted into the groove 75. After the movable cylinder 73 and the groove 75 cooperate with each other, it prevents the recycled asphalt raw materials from flying out of the grinding seat 3 during grinding and extrusion, playing a blocking role. The shape of the groove 75 is annular.

[0023] Meanwhile, the grinding groove 76 is formed at the top of the grinding seat 3 and is located inside the groove 75. The recycled asphalt raw materials are ground in the grinding groove 76. The shapes of both the grinding head 74 and the grinding groove 76 are frustum-shaped, and the grinding head 74 and the grinding groove 76 are adapted to each other. As the grinding head 74 rotates and moves down, the space between the grinding head 74 and the grinding groove 76 becomes smaller, causing the recycled asphalt raw materials to be squeezed and frictionally crushed at the same time, improving the grinding effect of the recycled asphalt raw materials. The outer surface of the grinding head 74 and the inner side wall of the grinding groove 76 are both provided with grinding bosses to increase the frictional force on the recycled asphalt raw materials and better crush the recycled asphalt raw materials. The bottom of the grinding seat 3 is provided with a discharge hole 9 communicating with the grinding groove 76 for discharging the ground recycled asphalt raw materials.

[0024] Please refer to Figure 2 and Figure 4 , a slot 10 communicating with the discharge hole 9 is formed on the outer surface of the grinding seat 3. A movable baffle 11 is inserted into the inner wall of the slot 10. The movable baffle 11 can move horizontally in the slot 10. When the movable baffle 11 no longer blocks the discharge hole 9, the ground recycled asphalt raw materials can be discharged. A fixing block 12 is fixedly installed on the movable baffle 11, and a mounting screw threadedly connected to the side wall of the grinding seat 3 is passed through the fixing block 12 for disassembling and assembling the movable baffle 11. A handle 13 is fixedly installed on the side wall of the movable baffle 11 and outside the fixing block 12, which is convenient for pulling the movable baffle 11. The top view shape of the handle 13 is U-shaped. A receiving bucket 14 is placed on the top of the bottom plate 1 and directly below the discharge hole 9 for collecting the ground recycled asphalt raw materials.

[0025] When this embodiment is in use, first pour the recycled asphalt raw materials into the grinding groove 76, start the servo motor 71, and the threaded column 72 rotates. Under the threaded connection between the threaded column 72 and the top wall of the support frame 4, the movable cylinder 73 and the grinding head 74 are driven to rotate and move down. The movable cylinder 73 is inserted into the groove 75. At this time, the space between the grinding head 74 and the grinding groove 76 becomes smaller, and under the rotation of the grinding head 74, the recycled asphalt raw materials can be squeezed and ground. After repeated squeezing and grinding, the recycled asphalt raw materials are ground into small particles. Unscrew the mounting screw and pull out the movable baffle 11 to discharge the small-particle recycled asphalt raw materials into the receiving bucket 14 for collection.

[0026] The beneficial effects of the above embodiment are:

[0027] The regenerated asphalt raw material grinding machine is provided with an extrusion and twisting component 7. After use, the extrusion and twisting component 7 drives the grinding head 74 connected to the threaded column 72 to rotate and move up and down under the threaded connection between the threaded column 72 and the top wall of the support frame 4, so that the space between the grinding head 74 and the grinding groove 76 gradually becomes smaller, and with the friction between the outer wall of the grinding head 74 and the inner wall of the grinding groove 76, the regenerated asphalt raw material can be squeezed and ground. The reduction in space will also cause the regenerated asphalt raw materials to be squeezed and ground against each other, prompting the regenerated asphalt raw materials to be ground into small particles, thereby achieving the purpose of fine grinding and ensuring the grinding effect of the regenerated asphalt raw materials.

[0028] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
