[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 1-5 The utility model provides the following technical solutions: a multi-layer sand and gravel screening machine for a quarry, comprising a main body box 1, a first screen plate 14 and a second screen plate 15 are fixedly installed inside the main body box 1, connecting plates 17 are fixedly installed on both left and right ends of the first screen plate 14, and mounting plates 18 are fixedly installed on both left and right ends of the second screen plate 15, mounting boxes 10 are fixedly installed on both left and right sides of the main body box 1, a driving motor 3 is fixedly installed on one side of the mounting box 10, a movable block 19 is fixedly installed on the driving motor 3 through the rotating shaft at the output end, and the connecting plate 17, the mounting plate 18 and the movable block 19 are all arranged inside the mounting box 10, and the movable block 19 is arranged between the connecting plate 17 and the mounting plate 18, and the movable block 19 is elliptical.

The arrangement of the threaded rod 20, the mounting block 21 and the fixed plate 22 can facilitate the placement of the device on the ground. Since the threaded rod 20 is threadedly connected to the mounting block 21, the mounting block 21 can be rotated to facilitate the adjustment of the positions of the mounting block 21 and the fixed plate 22 up and down, so that the device can be placed on different uneven ground. After that, the driving motor 3 is started to drive the movable block 19 to rotate through the rotating shaft at the output end. Since the movable block 19 is elliptical and the movable block 19 is arranged between the connecting plate 17 and the mounting plate 18, when the movable block 19 rotates, it can continuously drive the connecting plate 17, the mounting plate 18, the first screen plate 14 and the second screen plate 15 to vibrate up and down, so as to simultaneously drive the first screen plate 14 and the second screen plate 15 to vibrate up and down. Since the mesh apertures of the first screen plate 14 and the second screen plate 15 are different , so the purpose of screening materials of different particle sizes can be achieved, which is beneficial to increasing the practicality of the device. Since the movable door panel 9 is movably installed on the front of the main box 1 through the connecting hinge 2, the movable door panel 9 can be opened by the fixed handle 6 to clean out the materials inside the main box 1. In the screening process, since the connecting buckle 7 is slidably connected to the surface of the sliding track 8, the connecting buckle 7 can be moved downward so that the connecting buckle 7 is inserted into the inside of the connecting slot 5 to fix the movable door panel 9. The setting of the mounting handle 13 can facilitate the transportation of the device. The setting of the anti-slip sleeve can avoid the problem of hand slip when the user holds the mounting handle 13. As for the setting of the blanking plate 16, and since the blanking plate 16 is in the shape of a "human", the materials inside the main box 1 can slide outward through the discharge port 4, so that the materials inside the main box 1 can slide out, which increases the convenience of using the device. All electrical equipment in the device is powered by an external power supply.

[0024] In one aspect of the present embodiment, since the movable door panel 9 is movably mounted on the front side of the main box 1 via the connecting hinge 2, the movable door panel 9 can be conveniently opened via the fixed handle 6 to facilitate cleaning out the materials inside the main box 1. During the screening process, since the connecting buckle 7 is slidably connected to the surface of the sliding track 8, the connecting buckle 7 can be moved downward so that the connecting buckle 7 is inserted into the interior of the connecting slot 5 to facilitate fixing the movable door panel 9.

[0025] In one aspect of this embodiment, when the device is in use, the material can be poured into the interior of the main box 1 through the feed hopper 12 and the feed port 11, so as to facilitate the pouring of the material into the interior of the main box 1 to ensure the smooth progress of the material screening process. The arrangement of the threaded rod 20, the mounting block 21 and the fixed plate 22 can facilitate the placement of the device on the ground, and since the threaded rod 20 is threadedly connected to the mounting block 21, the mounting block 21 can be rotated to facilitate the up and down adjustment of the position of the mounting block 21 and the fixed plate 22, so that the device can be placed on different uneven ground.

[0026] In one aspect of the present embodiment, the setting of the mounting handle 13 can facilitate the carrying of the device, and the setting of the anti-slip cover can prevent the user from slipping when holding the mounting handle 13. As for the setting of the blanking plate 16, since the blanking plate 16 is in a "human" shape, it can facilitate the material inside the main box 1 to slide out through the discharge port 4, so as to facilitate the material inside the main box 1 to slide out, thereby increasing the convenience of using the device.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
