[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figures 1-6 , a stone conveying mechanism provided in this embodiment includes a frame 1, a belt 3 is arranged on the frame 1 through a driving roller 2, several support legs 4 are arranged at the bottom of the frame 1 and are evenly arranged along its length direction, and a cleaning mechanism 5 for scraping and flushing the dust and sediment on the surface of the belt 3 is arranged on the frame 1. A baffle 7 located on both sides of the belt 3 is arranged on the top of the frame 1 through a support rod 6.

[0025] In the present utility model, when using the stone conveying mechanism to convey stones, the conveying mechanism is placed on the working site through the support legs 4. The driving roller 2 on the frame 1 drives the belt 3 to move, and the stones are conveyed through the moving belt 3. During the conveying process, the baffle 7 on the support rod 6 plays a role of shielding and protection, preventing the stones on the belt 3 from falling during the conveying process. During the cyclic rotation of the belt 3, the cleaning mechanism 5 on the frame 1 can clean the dust, sediment and other impurities on the belt 3, avoid the increase of the resistance of the belt 3, ensure the conveying speed of the stones, and at the same time reduce the wear of the belt 3 and extend the service life of the conveying mechanism;

[0026] It should be noted that the driving roller 2 adopts the driving structure of an existing belt conveyor, and the motor group is used to drive the roller to rotate, and the belt 3 is driven to move in cooperation with several idlers in the middle of the frame 1.

[0027] Specifically, as Figure 2 and Figure 3As shown in the figure, the cleaning mechanism 5 includes a mounting plate 51 fixed to the side of the frame 1. A pressing roller 52 is provided on the mounting plate 51, and a cleaning brush 54 in contact with the belt 3 is provided on the mounting plate 51 at a position below the pressing roller 52 through a fixing plate 53.

[0028] Among them, the mounting plate 51 is fixed to the frame 1 by fasteners. The pressing roller 52 on the mounting plate 51 and the cleaning brush 54 on the fixing plate 53 clamp the belt 3, so as to ensure that the cleaning brush 54 on the fixing plate 53 can fully contact the belt 3. When the belt 3 moves in a cycle, the dust and sediment attached to the belt 3 can be brushed off by the cleaning brush 54, ensuring the cleanliness of the belt 3.

[0029] It should be noted that, as Figure 5 shown in the figure, the cleaning mechanism 5 further includes a flushing assembly 55. The flushing assembly 55 includes a fixed pipe 551 provided on the mounting plate 51 through a connecting frame 552. A nozzle 553 is provided on the fixed pipe 551, and a pipe joint 554 is provided at the middle position of the fixed pipe 551.

[0030] Among them, when it is necessary to thoroughly clean the belt 3 and remove the impurities that are difficult to scrape off on the belt 3, a flushing water pipe can be connected through the pipe joint 554 on the fixed pipe 551. The flushing water impacts on the belt 3 through the nozzle 553 on the fixed pipe 551, so as to wash away the impurities that are difficult to brush off on the belt 3, and then cooperate with the cleaning brush 54 to achieve thorough cleaning.

[0031] It should be noted that the nozzle 553 is arranged obliquely towards the belt 3 at a position close to the end of the fixed pipe 551. The obliquely arranged nozzle 553 can ensure that the sprayed flushing water can act on the belt 3 in a large range, and avoid the accumulation of dust and sediment on the nozzle 553 when the cleaning brush 54 is cleaning impurities, causing blockage of the nozzle 553.

[0032] Specifically, as Figures 2-4 shown in the figure, a chute 511 is opened on the mounting plate 51. A sliding seat 512 connected to the pressing roller 52 is provided in the chute 511 through an adjusting bolt 513. A guide rail 514 is provided on the sliding seat 512, and a guide groove 515 matching the guide rail 514 is opened on the chute 511.

[0033] Among them, the pressing roller 52 is rotatably installed on the sliding seat 512. When the belt 3 is relatively loose, in order to ensure that the cleaning brush 54 on the fixing plate 53 can effectively remove impurities, the sliding seat 512 is moved in the chute 511 by rotating the adjusting bolt 513, so that the pressure of the pressing roller 52 on the belt 3 increases, and the pressure of the cleaning brush 54 on the belt 3 becomes larger, improving the cleaning effect. The design of the guide rail 514 and the guide groove 515 can ensure the accurate movement of the sliding seat 512 and ensure that the sliding seat 512 will not deviate during movement.

[0034] Specifically, as Figure 4 and Figure 6 shown, an insertion plate 532 is provided at the end of the fixed plate 53 through a storage groove 531. A spring 533 is provided between the insertion plate 532 and the inner wall of the storage groove 531. A through hole 534 communicating with the storage groove 531 is formed at the bottom of the fixed plate 53, and a pull plate 535 penetrating through the through hole 534 is provided at the bottom of the insertion plate 532. A positioning hole 516 matching with the insertion plate 532 is formed on the mounting plate 51.

[0035] Among them, when it is necessary to clean and replace the cleaning brush 54 on the fixed plate 53, the insertion plate 532 is pulled by the pull plate 535 in the through hole 534, so that the insertion plate 532 compresses the spring 533 and moves towards the inside of the storage groove 531. After the insertion plate 532 is disengaged from the positioning hole 516, the fixed plate 53 can be removed from the mounting plate 51. Reverse operation can be performed during installation, thereby facilitating the cleaning and replacement of the cleaning brush 54.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
