[0015] 1. For this sand and stone separation device, through the design of the second clamping sleeve, the first spring and the cross bar, the sieve frame can move up and down reciprocally under the drive of the motor, so as to improve the screening efficiency. At the same time, during the movement of the sieve frame, the fixing rod will drive the hammer to strike the outer wall of the sieve frame, causing the sieve frame to vibrate, thereby further improving the screening efficiency of the sieve frame and effectively preventing the phenomenon of sieve holes being blocked, ensuring the continuity and high efficiency of the screening process.

[0029] In an embodiment of the present invention, in order to screen sand and gravel, specifically, the screening device 5 includes a motor 51. The motor 51 is fixedly connected to an outer wall of the barrel body 2. An output end of the motor 51 is fixedly connected with a rotating shaft 52. The rotating shaft 52 penetrates the barrel body 2 and is rotatably connected to the barrel body 2. A fixed sleeve 53 is penetrated by the rotating shaft 52 and is fixedly connected to the rotating shaft 52. A third spring 54 is fixedly connected to an outer wall of the fixed sleeve 53. One end of the third spring 54 far from the fixed sleeve 53 is fixedly connected with a first clamping sleeve 55. The first clamping sleeve 55 is penetrated by the rotating shaft 52 and is slidably connected to the rotating shaft ⑤. A pushing rod 56 is provided with a first clamping groove 561. The pushing rod 56 penetrates a sieve frame 57 and is rotatably connected to the sieve frame 57. The sieve frame 57 is provided with a discharge port 570. A sleeve body 571 is fixedly connected to an outer wall of the sieve frame 57. The sleeve body 571 is provided with an arc-shaped groove 572. The pushing rod 56 is penetrated by the rotating shaft 52 and is rotatably connected to the rotating shaft 52. The rotating shaft 52 penetrates a second clamping sleeve 58 and is rotatably connected to the second clamping sleeve 58. The second clamping sleeve 58 is provided with a second clamping groove 580;

[0030] Furthermore, a fixing ring 23 is fixedly connected to an inner wall of the barrel body 2. Guide rods 232 are fixedly connected to an outer wall of the fixing ring 23. The guide rods 232 penetrate the sieve frame 57 and are slidably connected to the sieve frame 57. A first spring 231 is fixedly connected to an outer wall of the fixing ring 23. One end of the first spring 231 far from the fixing ring 23 is fixedly connected to an outer wall of the sieve frame 57;

[0031] Furthermore, a hammer 24 is hinged to an inner wall of the barrel body 2. The hammer 24 is provided with a sliding groove 25. The sliding groove 25 is sleeved with a fixing rod 573. The fixing rod 573 is fixedly connected to an outer wall of the sieve frame 57;

[0032] Furthermore, a second clamping block 551 is slidably connected to the first clamping sleeve 55. A fourth spring 552 is fixedly connected to an outer wall of the second clamping block 551. One end of the fourth spring 552 far from the second clamping block 551 is fixedly connected to an inner wall of the first clamping sleeve 55;

[0033] Further, a first clamping block 521 is slidably connected to the rotating shaft 52. An outer wall of the first clamping block 521 is fixedly connected to a second spring 522. One end of the second spring 522 away from the first clamping block 521 is fixedly connected to an inner wall of the rotating shaft 52;

[0034] In the present utility model, during use, first, sand and gravel are poured into the interior of the barrel body 2 through the feed hopper 3. At this time, the sieve frame 57 will perform a preliminary screening on the sand and gravel. Subsequently, the output end of the control motor 51 rotates clockwise. At this time, the first clamping block 521 will apply a force to the second clamping groove 580, so that the second clamping sleeve 58 rotates synchronously with the rotating shaft 52. During this process, the first clamping sleeve 55 will rotate synchronously with the rotating shaft 52. At this time, the first clamping groove 561 will apply a force to the second clamping block 551, so that the second clamping block 551 completely enters the interior of the first clamping sleeve 55. When the second clamping sleeve 58 rotates, at this time, a cross bar on the second clamping sleeve 58 will indirectly apply a force to the sleeve body 571, so that the sieve frame 57 moves upward. At the same time, the first spring 231 undergoes elastic deformation. When the force exerted by the cross bar on the sleeve body 571 disappears, at this time, the sieve frame 57 will return to its original position under the action of the first spring 231 and gravity. Through the cooperation of the second clamping sleeve 58, the first spring 231 and the cross bar, the sieve frame 57 moves up and down reciprocally inside the barrel body 2, thereby improving the screening efficiency of the sieve frame 57;

[0035] When the sieve frame 57 moves upward, at this time, a fixing rod 573 fixedly connected to an outer wall of the sieve frame 57 will apply a force to the hammer 24, so that the hammer 24 rotates around the hinge point with the inner wall of the barrel body 2, thereby knocking on the outer wall of the sieve frame 57, causing the sieve frame 57 to vibrate, thereby further improving the screening efficiency of the sieve frame 57;

[0036] When the screening of the sand and gravel is completed, the cover body 21 is opened. Subsequently, the driving motor 51 rotates counterclockwise. At this time, the second clamping block 551 on the first clamping sleeve 55 will apply a force to the first clamping groove 561, so that the push rod 56 rotates. At the same time, the second clamping groove 580 will apply a force to the first clamping block 521, so that the first clamping block 521 completely enters the interior of the rotating shaft 52. When the push rod 56 rotates, at this time, the push rod 56 will push the stones inside the sieve frame 57 outwards, so as to discharge the stones from the discharge port 570.
