[0036] A feeding mechanism, which is arranged on the right side of the top of the bottom plate 1;

[0037] Among them, the feeding mechanism includes a support frame 6, the bottom of the support frame 6 is fixedly connected to the top of the bottom plate 1, and fixed plates 7 are fixedly installed on the front and rear sides of the top of the support frame 6. A limit plate 8 is fixedly installed between the fixed plates 7. A slider 9 is movably sleeved inside the limit plate 8. A discharge box 10 is fixedly installed between the sliders 9. The outer surface of the discharge box 10 is movably connected to the outer surface of the support frame 6. A feed box 11 is fixedly installed on the top of the discharge box 10, and a round rod 15 is fixedly installed on the right side of the discharge box 10. The movement of the round rod 15 will drive the discharge box 10 to move;

[0038] The driving mechanism is arranged on the top of the inner surface of the supporting frame 6 .

[0039] The operator can pour sand and gravel into the discharge box 10 through the feed box 11. Since the bottom of the inner cavity of the discharge box 10 is inclined, the sand and gravel can slide from the left side of the bottom of the discharge box 10 to the inside of the shell 5. When the round rod 15 moves, it will drive the discharge box 10 to move, so that the sand and gravel falling through the discharge box 10 can fall into the inside of the shell 5 evenly, avoiding the sand and gravel from accumulating in one place after falling into the shell 5, thereby improving the screening efficiency of sand and gravel. Due to the design of the baffle 38, the sand and gravel are prevented from splashing to the outside during the falling process.

[0040] The driving mechanism includes:

[0042] The inner wall of the rotating rod 14 is fixedly sleeved with the outer surface of the rotating shaft 13 , and the inner surface of the rotating rod 14 is movably connected with the outer surface of the round rod 15 .

[0043] The operator starts the first motor 12 so that the rotating shaft 13 drives the rotating rod 14 to move, so that the inner surface of the rotating rod 14 can squeeze and push the round rod 15 to move, and then the round rod 15 can drive the discharge box 10 to move.

[0044] Among them, the inner cavity of the shell 5 is movably connected with a first sieve plate 16, the left side of the shell 5 is fixedly installed with a first discharge plate 17, the inner cavity of the shell 5 is movably connected with a second sieve plate 18 located below the first sieve plate 16, and the left side of the shell 5 is fixedly installed with a second discharge plate 19 located below the first discharge plate 17.

[0045] The diameter of the sieve holes of the first sieve plate 16 is greater than the diameter of the sieve holes of the second sieve plate 18 , so that the first sieve plate 16 and the second sieve plate 18 can perform multi-stage screening on the stone.

[0046] A mounting plate 20 is fixedly mounted on the front of the first sieve plate 16 and the second sieve plate 18 , and a handle 21 is fixedly mounted on the front of the mounting plate 20 .

[0049] By providing the circular shaft 22 , the clamping block 23 can rotate with the circular shaft 22 as the axis.

[0050] Among them, the back sides of the first sieve plate 16 and the second sieve plate 18 are fixedly installed with mounting blocks 24, the inner surface of the mounting block 24 is movably connected to the outer surface of the clamping block 23, the inner part of the mounting block 24 is movably sleeved with a pull rod 27, the right end of the pull rod 27 is fixedly connected with a movable block 25, the outer surface of the movable block 25 is movably sleeved with the inner surface of the mounting block 24, and the right end of the movable block 25 passes through the mounting block 24 and extends to the outside of the mounting block 24.

[0051] The operator can pull the pull rod 27 to the left, thereby driving the movable block 25 to move to the left, thereby releasing the fixation of the clamping block 23 .

[0052] The left side of the movable block 25 is fixedly connected with a return spring 26 , and the left end of the return spring 26 is fixedly connected to the inner wall of the mounting block 24 . The return spring 26 pushes the movable block 25 to move under the action of elastic force.

[0053] By providing the return spring 26 , the return spring 26 can push the movable block 25 to the right to return to its original position under the action of elastic force recovery.

[0054] Among them, a second motor 28 located on the front side of the shell 5 is fixedly installed on the top of the side panel 2, and the other end of the output shaft of the second motor 28 is fixedly connected to a rotating shaft 29. The other end of the rotating shaft 29 passes through the side panel 2 and extends to the inside of the side panel 2 and is movably connected to the inner wall of the side panel 2. An elliptical block 30 is fixedly connected to the outer surface of the rotating shaft 29, and the outer surface of the elliptical block 30 is movably connected to the bottom of the shell 5.

[0055] The operator can start the second motor 28 to make the rotating shaft 29 drive the elliptical block 30 to rotate, so that the elliptical block 30 can squeeze and push the shell 5 to vibrate, thereby screening the sand and gravel.

[0057] By providing the nozzle 34 , the nozzle 34 can spray water mist into the interior of the shell 5 , thereby preventing dust inside the shell 5 from being dispersed to the outside.

[0058] A blanking plate 35 is fixedly mounted on the left side of the bottom of the shell 5 , and a through hole 36 is formed at the bottom of the blanking plate 35 .

[0059] By providing the through hole 36 , the water sprayed by the nozzle 34 can pass through the through hole 36 and fall into the interior of the collection box 37 , thereby preventing the water from mixing with the sand and gravel.

[0060] Working principle and usage process:

[0061] First, the operator starts the second motor 28, so that the rotating shaft 29 drives the elliptical block 30 to rotate, so that the elliptical block 30 can squeeze and push the shell body 5 to move upward, and the elliptical block 30 will stop pushing the shell body 5 when it continues to rotate. The vibration spring 3 will drive the shell body 5 to reset under the action of elastic recovery. As the elliptical block 30 continues to rotate, it will continuously squeeze and push the shell body 5, so that the shell body 5 can vibrate. The operator can pour the stones to be screened into the inside of the discharge box 10 through the feed box 11, and then start the first motor 12, so that the rotating shaft 13 can drive the rotating rod 14 to rotate, and then the inner surface of the rotating rod 14 squeezes and pushes the round rod 15 to move, so that the round rod 15 drives the discharge box 10 to move, and then the stones falling through the discharge box 10 can evenly fall onto the upper surface of the first screen plate 16, avoiding the stones from piling up, so that the stones can be quickly dispersed, thereby improving the screening efficiency.

[0062] When performing screening operations, the operator can start the water pump 31 so that the water inlet pipe 32 can suck water, and then spray it out from the nozzle 34 through the water outlet pipe 33, so as to reduce dust inside the shell 5 and prevent the dust inside the shell 5 from drifting to the outside and causing pollution. The screened stones will be discharged through the first discharge plate 17, the second discharge plate 19 and the lower plate 35 respectively, and the water sprayed by the nozzle 34 will fall into the lower plate 35, and then fall into the collection box 37 through the through hole 36, thereby preventing the stones and water from mixing together.

[0063] When the operator needs to disassemble the first sieve plate 16 or the second sieve plate 18, the operator can pull the pull rod 27 outward, so that the pull rod 27 drives the movable block 25 to move outward, so that the movable block 25 enters the interior of the mounting block 24, thereby releasing the fixation of the clamping block 23, and then the operator rotates the clamping block 23 to make the clamping block 23 disengage from the interior of the mounting block 24, thereby releasing the fixation of the first sieve plate 16. At this time, the operator can pull the handle 21 outward to remove the first sieve plate 16 from the interior of the shell 5, which facilitates the operator to repair and replace the first sieve plate 16 or the second sieve plate 18.
