A cam 17 is fixedly connected to the surface of the rotating rod 16. The cam 17 is slidably connected to the bottom surface of the sand flow grooves 13.
[0021] Reference Figure 1 , reciprocating telescopic rods 18 are provided at both ends on the left side of the separation box 1. A T-shaped plate 19 is fixedly connected to the top of the reciprocating telescopic rod 18. A round rod 20 is fixedly connected to the bottom surface of the right end of the T-shaped plate 19. A number of pressing plates 21 are fixedly connected to both sides of the surface of the round rod 20. The bottom end of the round rod 20 is conical.
[0022] As a technical optimization scheme of the present utility model, through the setting of the round rod 20, when the sand and gravel mixture is put in through the feeding port 2, if the sand and gravel are put in quickly, it will cause the through port on the left side of the guide plate 3 to be blocked. At this time, the reciprocating telescopic rod 18 can be started to drive the T-shaped plate 19 to descend. The T-shaped plate 19 drives the round rod 20 and the pressing plates 21 to descend to dredge the sand and gravel, avoiding the problem that the separation efficiency is affected due to the blockage of the feeding port 2, and further improving the practicability of the device.
[0023] Reference Figure 1 , a water tank 22 is fixedly connected to the left side of the separation box 1. A water pump 23 is fixedly connected to the top of the water tank 22. A water pipe 24 is communicated with the left side of the water tank 22. The output end of the water pipe 24 is communicated with the input end of the water pump 23. An atomizing nozzle 25 is provided on the right side of the water pump 23. The bottoms of the reciprocating telescopic rods 18 are fixedly connected to the water tank 22.
[0024] As a technical optimization solution of the present utility model, through the setting of the water pump 23, the water pump 23 is started to draw water flow from the inside of the water tank 22 through the water pipe 24 and then sprayed out through the atomizing nozzle 25, which can play a role in dust reduction for the dust generated when the sand and gravel raw materials are put in, and avoid the harm to the health of the staff by inhaling it into the body.
[0025] Reference Figure 1 , the output end of the water pump 23 is communicated with a hollow frame 26. The hollow frame 26 is located at the top of the separation box 1 and is fixedly connected thereto. The number of atomizing nozzles 25 is several, and the top and the inside of the hollow frame 26 are both communicated with the atomizing nozzles 25.
[0026] As a technical optimization solution of the present utility model, through the setting of the hollow frame 26, the dust reduction range and the dust reduction direction are greatly increased, thereby further improving the dust reduction effect, avoiding environmental pollution, and making the device more environmentally friendly.
[0027] Reference Figure 2 and Figure 3 , the right ends of the sieve plate 4 and the lifting plate 12 are both inclined downward, and the rear end of the sand guiding plate 7 is higher than the front end.
[0028] As a technical optimization solution of the present utility model, through the setting that the right ends of the sieve plate 4 and the lifting plate 12 are both inclined downward and the rear end of the sand guiding plate 7 is higher than the front end, the discharging speed of the gravel and stones is accelerated, and the accumulation of the gravel and stones inside the separation box 1 affecting the separation efficiency is avoided, and the bottom wall of the stone discharging port 5 is higher than the surface of the right end of the sieve plate 4, so as to avoid the gravel from being discharged through 105.
[0029] Reference Figure 1 、 Figure 2 and Figure 4 , the height of the left sliding groove 8 is greater than that of the right side. The tops of the springs 10 are both fixedly connected with leveling blocks 27. The leveling blocks 27 are both slidably connected with the sliding grooves 8. The tops of the leveling blocks 27 are both fixedly connected with the connecting blocks 11. The surfaces of the tops of the two leveling blocks 27 are both located on the same horizontal plane. Protective covers 28 are fixedly connected to both sides of the separation box 1, and the height of the left protective cover 28 is greater than that of the right side.
[0030] As a technical optimization solution of the present utility model, through the setting of the leveling blocks 27, it is avoided that due to the inclination of the sieve plate 4 and the lifting plate 12, the stretching distances of the connecting blocks 11 by the springs 10 on both sides are inconsistent, resulting in the problem that the probing needles 14 on the right side cannot be completely inserted into the sieve holes on the right side of the sieve plate 4 for dredging, so that the device is more practical, and 128 the situation that the staff is accidentally touched and pinched is avoided.
[0031] Working principle and usage process of the utility model: During use, the user first starts the water pump 23 to pump water from the inside of the water tank 22 through the water pipe 24, and then the water flows into the inside of the hollow frame 26 and is sprayed out by several atomizing nozzles 25 for dust reduction. Subsequently, the sand and gravel raw materials are put in through the feeding port 2, and at the same time, the reciprocating telescopic rod 18 is started to be in an operating state. The reciprocating telescopic rod 18 will drive the T-shaped plate 19 to move up and down back and forth. The T-shaped plate 19 drives the round rod 20 and the pressing plate 21 to move up and down back and forth to dredge the sand and gravel, avoiding the problem that the feeding port 2 is blocked due to the relatively fast input of sand and gravel. The falling sand and gravel are filtered by the sieve plate 4, and the stones are discharged through the stone discharge port 5. The gravel falls onto the surface of the sand guiding plate 7 and is discharged through the sand discharge port 6. Then, the motor 15 is started to make the rotating rod 16 rotate. The rotating rod 16 drives the cam 17 to rotate. When the left end of the cam 17 rotates to the bottom of the lifting plate 12 and slides with it, the lifting plate 12 is forced to extend upward. The lifting plate 12 drives the connecting block 11 to move upward and stretches the spring 10 at the bottom upward. The lifting plate 12 drives the probing thorn 14 to extend upward and pass through the sieve holes, and pushes out the stones blocked inside the sieve holes. When the left end of the cam 17 separates from the lifting plate 12, the spring 10 contracts, thereby driving the lifting plate 12 and the probing thorn 14 to separate from the sieve plate 4 to complete automatic dredging, avoiding the blockage of the sieve plate 4.
