DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1-4 The utility model provides a technical solution: a drying drum used for asphalt regeneration, comprising a drying drum 1 and a cleaning mechanism 4, the discharge end of the drying drum 1 is sealed and connected with a discharge drum end seat 2, the inner wall of the drying drum 1 is fixedly connected with a copying plate 3, and a cleaning mechanism 4 is arranged on one side of the discharge end surface of the drying drum 1;

[0023] The cleaning mechanism 4 includes a scraper 415, a mounting base 402 is threadedly connected to one side of the surface of the drying cylinder 1, a mounting groove 405 is provided on one side of the surface of the mounting base 402, a limiting groove 406 is provided inside the mounting base 402, a return spring 407 is provided inside the limiting groove 406, one end of the return spring 407 is fixedly connected to a limiting block 408, one end of the limiting block 408 is fixedly connected to a steel cable 409, a mounting block 412 is embedded in the mounting groove 405, a mounting plate 414 is fixedly connected to one side of the surface of the mounting block 412, and a mounting plate 414 is fixed on one side of the surface of the mounting plate 414. The scraper 415 is connected. When in use, the mounting base 402 is firstly attached to one side of the surface of the drying cylinder 1, and the threaded hole 403 opened on one side of the mounting base 402 is aligned with the threaded groove 401 opened on one side of the surface of the drying cylinder 1. Then the bolt 404 is passed through the threaded hole 403 and is threadedly connected to the drying cylinder 1 through the threaded groove 401. At this time, the mounting base 402 is fixed to one side of the surface of the drying cylinder 1, and then the handle 411 is pulled. At this time, the handle 411 drives the connecting plate 410 to move away from the mounting base 402. Since one end of the steel cable 409 passes through the mounting base 402, The mounting base 402 is fixedly connected to the connecting plate 410, and the other end of the steel cable 409 is fixedly connected to the limit block 408, so that the connecting plate 410 moves through the steel cable 409 to drive the limit block 408 to move. At this time, the limit block 408 moves toward the inside of the limit groove 406, and at the same time, the limit block 408 squeezes the return spring 407 to compress and deform the return spring 407. When the limit block 408 is completely embedded in the inside of the limit groove 406, the mounting block 412 equipped with the scraper 415 is slid into the inside of the mounting groove 405. When the mounting block 412 is completely embedded in the inside of the mounting groove 405, , the slot 413 opened on one side of the surface of the mounting block 412 is aligned with the position of the limit slot 406, and then the force applied to the handle 411 is released. At this time, the return spring 407 loses its force and rebounds, thereby driving the limit block 408 to return to its original position. At this time, one end of the limit block 408 is embedded in the slot 413, so that the limit block 408 fixes the mounting block 412 in the mounting slot 405. At this time, one side of the scraper 415 is in contact with the inner wall of the discharge roller end seat 2, so that the scraper 415 can scrape off the asphalt adhering to the inner wall of the discharge roller end seat 2.

[0024] Furthermore, a threaded hole 403 is provided on one side of the surface of the mounting base 402, a bolt 404 passes through the inside of the threaded hole 403, and the threaded hole 403 is consistent with the size of the threaded groove 401. Through the arrangement of the threaded groove 401 and the threaded hole 403, when one end of the bolt 404 passes through the threaded hole 403 and is threadedly connected to the drying cylinder 1 through the threaded groove 401, the mounting base 402 can be fixed on one side of the surface of the drying cylinder 1.

[0025] Furthermore, the other end of the steel cable 409 is fixedly connected to a connecting plate 410, and a handle 411 is installed on one side of the surface of the connecting plate 410. One end of the steel cable 409 passes through the interior of the reset spring 407. Through the setting of the steel cable 409, when the handle 411 is pulled, the handle 411 drives the steel cable 409 to move through the connecting plate 410. Since the other end of the steel cable 409 is fixedly connected to the limit block 408, the steel cable 409 can transfer the force applied to the handle 411 to the limit block 408, thereby driving the limit block 408 to move.

[0026] Furthermore, a slot 413 is provided on one side of the surface of the mounting block 412, the mounting slot 405 is a "T"-shaped slot, the mounting block 412 is a "T"-shaped block, the mounting slot 405 and the mounting block 412 are of the same size, and one end of the limit block 408 is embedded in the slot 413. Through the arrangement of the mounting slot 405 and the mounting block 412, since the mounting slot 405 is a "T"-shaped slot, the mounting block 412 is a "T"-shaped block and the mounting slot 405 and the mounting block 412 are of the same size, when the mounting block 412 is embedded in the mounting slot 405, the connection between the mounting block 412 and the mounting base 402 can be made more stably.

[0027] Furthermore, one end of the return spring 407 is fixedly connected to the mounting base 402 inside the limit groove 406, and one end of the limit block 408 is embedded in the limit groove 406. Through the setting of the return spring 407, when in use, based on the characteristics of the return spring 407, when the return spring 407 is subjected to an extrusion force, it will be compressed and deformed. When the force disappears, the compressed return spring 407 will rebound and deform, so that the return spring 407 will not affect its movement when the limit block 408 moves. When the force applied to the limit block 408 disappears, the rebound deformation of the return spring 407 can drive the limit block 408 to return to its original position.

[0028] Furthermore, the scraper 415 is made of stainless steel, and three groups of scrapers 415 are provided. Through the provision of the scraper 415, the stainless steel scraper 415 can have a longer service life, can perform asphalt scraping operations for a long time, and reduce the occurrence of damage that affects the scraping effect.

[0029] Furthermore, one side of the scraper 415 is in contact with the inner wall of the discharge roller end seat 2. Through the setting of the scraper 415, when in use, since one side of the scraper 415 is in contact with the inner wall of the discharge roller end seat 2, the scraper 415 can effectively scrape off the asphalt adhering to the inner wall of the discharge roller end seat 2.

[0030] Working principle: first, fit the mounting base 402 to one side of the surface of the drying cylinder 1, and at the same time, align the threaded hole 403 opened on one side of the surface of the mounting base 402 with the threaded groove 401 opened on one side of the surface of the drying cylinder 1, and then pass the bolt 404 through the threaded hole 403 and threadedly connect it to the drying cylinder 1 through the threaded groove 401. At this time, fix the mounting base 402 to one side of the surface of the drying cylinder 1, and then pull the handle 411. At this time, the handle 411 drives the connecting plate 410 to move away from the mounting base 402. Since one end of the steel cable 409 passes through the mounting base 402 and is fixedly connected to the connecting plate 410, and the other end of the steel cable 409 is fixedly connected to the limit block 408, the connecting plate 410 moves through the steel cable 409 to drive the limit block 408 to move. At this time, the limit block 408 moves toward the inside of the limit groove 406, and at the same time, the limit block 408 squeezes the return spring 407 to compress the return spring 407. When the mounting block 412 is fully engaged in the limiting groove 406, the mounting block 412 equipped with the scraper 415 is slid into the mounting groove 405. When the mounting block 412 is fully engaged in the mounting groove 405, the slot 413 opened on one side of the surface of the mounting block 412 is aligned with the limiting groove 406. Then the force applied to the handle 411 is released. At this time, the return spring 407 loses its force and rebounds, thereby driving the limiting block 408 to return to its original position. At this time, one end of the limiting block 408 is engaged in the slot 413, so that the limiting block 408 fixes the mounting block 412 in the mounting groove 405. At this time, one side of the scraper 415 is in contact with the inner wall of the discharge roller end seat 2, so that the scraper 415 can scrape off the asphalt adhering to the inner wall of the discharge roller end seat 2, and place the asphalt in the drying cylinder 1. When passing through the copying plate 3, the asphalt is dried over a large area, and then discharged through the discharge roller end seat 2.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
