[0027] The machine body 1 inside is connected with the screening barrel 12 through a rotating mechanism, the rotating mechanism comprises the second motor 8, the worm 9, the worm gear 10, the rotating rod 11 and the screening barrel 12, the machine body 1 inside is connected with the second motor 8, the second motor 8 is connected with the worm 9, the worm 9 is engaged with the worm gear 10, the worm gear 10 is connected with the rotating rod 11, the rotating rod 11 is fixedly connected with the screening barrel 12, the machine body 1 inside is provided with the sieve plate 16, the sieve plate 16 is fixedly connected with the vibration motor 15, the machine body 1 inside is connected with the adjusting plate 22 through an adjusting mechanism, the adjusting mechanism comprises the third motor 17, the lead screw 18, the transmission belt 19, the sliding block 20, the moving block 21, the adjusting plate 22 and the supporting rod 23, the machine body 1 inside is fixedly connected with the third motor 17, the third motor 17 is connected with the lead screw 18, the lead screw 18 is connected with the transmission belt 19, the lead screw 18 is threadedly connected with the sliding block 20, the sliding block 20 is fixedly connected with the moving block 21, the moving block 21 is connected with the adjusting plate 22, the adjusting plate 22 is hingedly connected with the supporting rod 23, the tail of the supporting rod 23 is hingedly connected with the upper side of the machine body 1, the lead screw 18 is symmetrically arranged about the center of the transmission belt 19, the sliding block 20 is connected with the adjusting plate 22 at both ends, the adjusting plate 22 is connected with the baffle 27 through a buffer mechanism, the buffer mechanism comprises the adjusting plate 22, the fixed rod 24, the spring 25, the connecting block 26 and the baffle 27, the adjusting plate 22 inside is fixedly connected with the fixed rod 24, the surface of the fixed rod 24 is provided with the spring 25, the upper end of the fixed rod 24 is slidingly connected with the connecting block 26 inside, the connecting block 26 is slidingly connected with the adjusting plate 22 inside, and the upper end of the connecting block 26 is fixedly connected with the bottom of the baffle 27.

[0028] At this time, the second motor 8 is started to drive the worm 9 to rotate. Since the worm 9 and the worm wheel 10 are engaged, the worm wheel 10 drives the rotating rod 11 to rotate at this time, so that the rotating rod 11 drives the screening barrel 12 to rotate. At this time, the screening barrel 12 swings left and right, and the swing degree is not more than 120 degrees. The screening barrel 12 screens the stones. After the screened stones fall above the screen plate 16 below, the vibration motor 15 is started to drive the screen plate 16 to screen. Since the screen plate 16 is slightly inclined, the stones roll to one side during the screening process at this time. The larger stones are left on the screen plate 16 and move left and right. The smaller stones fall above the baffle 27 below. Since the screen holes in the screening barrel 12 are larger than the screen holes of the screen plate 16, the stones can be screened into different sizes in multiple stages. When the stones above the screen plate 16 are all taken out, the rotating angle of the screening barrel 12 is more than 180 degrees, so that the stones left inside can roll above the screen plate 16 and then move left to fall outside. During the screening process, the third motor 17 is started to drive the lead screw 18 to rotate, so that the transmission belt 19 above the lead screw 18 rotates synchronously. The lead screws 18 on both sides rotate at the same time. At this time, the sliding block 20 above the lead screw 18 drives the moving block 21 to move at the same time, so that the moving block 21 drives the adjusting plate 22 to adjust through the hinge shaft. At the same time, the adjusting plate 22 adjusts the angle through the hinge shaft and cooperates with the support rod 23 to adjust the angle, so that the adjusting plate 22 adjusts the angle and inclines. At this time, the baffle 27 above the baffle 27 inclines synchronously. After the stones fall above the baffle 27, the baffle 27 drives the connecting block 26 to slide above the fixed rod 24. At the same time, the spring 25 on the surface of the fixed rod 24 is contracted, so that the baffle 27 is buffered. The stones are prevented from being too large in force and being damaged on the baffle 27 above. In use, only the corresponding receiving device needs to be placed at the discharge port on the left side of the machine body 1 to collect the screened stones.

[0029] Working principle: in the use of stone production with screening device, use when the stone through the body 1 right side into after, at this time start the first motor 2 in the body 1 drive comminution shaft 3 rotation, make comminution shaft 3 one end drive first gear 4 rotation, because first gear 4 and second gear 5 meshing, make both sides comminution shaft 3 synchronous rotation, to the input stone comminution, prevent stone block head is bigger, at this time after comminution stone through the conveyor belt 6 drive surface multiple fixed plate 7 move, because fixed plate 7 bending setting, can better the stone is transported to the top after entering into the screening bucket 12 inside, start dust collector 13 at the same time, the dust generated after entering into the dust collection box 14 inside, at this time start second motor 8 drive worm 9 rotation, because worm 9 and worm wheel 10 meshing, at this time worm wheel 10 drive rotating rod 11 rotation, make rotating rod 11 drive screening bucket 12 rotation, at this time screening bucket 12 left and right swing, swing degree not more than 120 degrees, screening bucket 12 to stone screening, after screening stone drop to the lower side of the screen plate 16 above, start vibration motor 15 drive screen plate 16 screening, because screen plate 16 slightly inclined setting, at this time the stone in the screening process to one side rolling, larger stone residue in screen plate 16 above direction left and right movement, smaller stone drop to the lower side of the baffle 27 above, because the screen hole in the screening bucket 12 inside is greater than the screen hole of screen plate 16, can carry out multistage screening of stone and screen the stone into different size, when the stone on the screen plate 16 above is taken out, the rotating angle of the screening bucket 12 is more than 180 degrees, which can make the residual stone in the interior roll to the screen plate 16 above and then move to the left side and drop to the outside. In the screening process, the third motor 17 drives the screw rod 18 to rotate, so that the transmission belt 19 above the screw rod 18 rotates synchronously. The two screw rods 18 rotate at the same time. At this time, the sliding block 20 above the screw rod 18 drives the moving block 21 to move at the same time, so that the moving block 21 drives the adjusting plate 22 to adjust through the hinge shaft. At the same time, the adjusting plate 22 adjusts the angle through the hinge shaft and the supporting rod 23, so that the adjusting plate 22 adjusts the angle and inclines, so that the baffle 27 above inclines synchronously. At this time, the stone falls on the baffle 27 above, the baffle 27 drives the connecting block 26 to slide on the fixed rod 24, and the spring 25 on the surface of the fixed rod 24 contracts, so that the baffle 27 is buffered to prevent the stone from being damaged by excessive force on the baffle 27 above. In use, only the corresponding receiving device is placed at the discharge port of the body 1 left side to collect the screened stone, thereby completing a series of work. The contents not described in detail in the specification belong to the existing technology known to those skilled in the art.

[0030] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
