DETAILED DESCRIPTION

[0030] 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.

[0031] See also Figure 1-8 The utility model provides a technical solution: an assembled highway maintenance gravel screening mechanism, including a feeding barrel 1, an adjusting mechanism 2, an adjusting plate 3, a movable column 4, a connecting bracket 5, a spring 6, a fixing block 7, a screening box 8, a screen 9, an electric telescopic rod 10, a connecting column 11, a vertical plate 12, a fixing bracket 13, a mounting frame 14 and a mounting bolt 15.

[0032] When using the assembled highway maintenance gravel screening mechanism, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the gravel required for highway maintenance is screened, an adjusting mechanism 2 is arranged inside the feeding barrel 1, and the adjusting mechanism 2 includes an adjusting plate 3 rotatably connected to the left and right sides of the feeding barrel 1, a movable column 4 fixedly connected to the front end of the adjusting plate 3, a connecting bracket 5 for limiting and a spring 6 sleeved on the middle of the connecting bracket 5. By pulling the connecting bracket 5, the connecting bracket 5 slides with the movable column 4, and the connecting bracket 5 squeezes the spring 6, so that the spring 6 undergoes elastic deformation. At this time, the connecting bracket 5 is separated from the fixed block 7, thereby releasing the limit between the movable column 4 and the feeding barrel 1;

[0033] Then, by rotating the movable column 4, the movable column 4 rotates on the front side of the feeding barrel 1. At this time, the movable column 4 drives the adjusting plate 3 to flip inside the feeding barrel 1, so as to indirectly adjust the opening size of the lower end of the feeding barrel 1. When the adjustment is completed, the connecting bracket 5 is directly loosened. At this time, the spring 6 restores its elastic deformation, driving the connecting bracket 5 and the movable column 4 to slide, so that the connecting bracket 5 and the fixed block 7 at the corresponding position are engaged, thereby facilitating the limiting of the movable column 4 and the feeding barrel 1. Through the above operation, it is convenient to adjust the feeding rate of the stone during screening, prevent the device from being blocked during feeding, and prevent the stone from being excessively accumulated on the screen 9 during screening, affecting the actual screening effect;

[0034] After the adjustment is completed, the screened stones are directly added to the feeding cylinder 1, and the stones fall down through the feeding cylinder 1 into the screen 9 inside the screening box 8, and are screened by the screen 9. Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, during the screening process, the electric telescopic rod 10 installed at the lower end of the feeding barrel 1 can be started, and the electric telescopic rod 10 drives the screening box 8 and the screen 9 to move left and right at the lower end of the feeding barrel 1 through the connecting column 11, thereby greatly improving the actual screening efficiency, and the screening box 8 drives the vertical plate 12 and the fixed bracket 13 to slide, so that the movement of the screening box 8 at the lower end of the feeding barrel 1 is more stable;

[0035] In addition, after the screening is completed, the power is turned off and the mounting bolt 15 can be rotated, and the mounting bolt 15 and the screening box 8 are threadedly connected, so that the mounting bolt 15 is disengaged from the screening box 8 and the mounting frame 14, thereby loosening the limit between the mounting frame 14 and the screening box 8, and then the mounting frame 14 is pulled downward, and the mounting frame 14 drives the screen 9 to move downward, thereby facilitating the disassembly and cleaning of the screen 9, and at the same time, the enlarged stones screened out can be removed.

[0036] Although the 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.
