Although the device has many beneficial effects, the cleaning system performs cleaning after screening the river sand, and the process is complicated and not streamlined enough. In view of this, we propose a river sand grading and cleaning device. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example:

[0022] See also Figure 1-3 A river sand grading and cleaning device includes a base 1, on which are arranged a plurality of cylinders 2, the bottom end of the cylinder 2 located above extends into the cylinder 2 below it, and two adjacent cylinders 2 are connected and fixed, and a filter screen 201 is arranged at the bottom of the cylinder 2, and the aperture of the filter screen 201 at the bottom of each cylinder 2 decreases from top to bottom. The plurality of cylinders 2 are vertically stacked in sequence, and the filter screens 201 with different apertures at the bottom of the cylinder 2 are arranged. When the river sand flows into the upper cylinder 2, the large particles of river sand will be blocked by the upper filter screen 201, and the small particles of river sand fall into the lower cylinder 2, and the river sand is classified according to the particle size through the multiple filter screens 201, and then water is injected into the cylinder 2 to clean the river sand.

[0023] A stirring assembly 3 is provided within the cylinder 2. The stirring assembly 3 stirs the river sand to facilitate cleaning of the river sand. A drive motor 4 is provided on the base 1. A rotating shaft 5 is connected to the output shaft of the drive motor 4. The rotating shaft 5 passes through multiple filter screens 201 in sequence. The rotating shaft 5 is rotatably connected to the middle of the filter screens 201. The stirring assembly 3 is movably connected to the rotating shaft 5. The driving motor 4 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the stirring assembly 3 to stir and clean the river sand.

[0024] In this application, support frames 6 are provided on opposite sides of the base 1 to fix the cylinder 2. The number of cylinders 2 can also be set according to the size of the river sand to be classified. A mounting shaft 7 is provided on both side walls of one of the cylinders 2, and the mounting shaft 7 is rotatably connected to the support frame 6. The base 1 is provided with multiple sets of cylinders 8, which are arranged at an angle. The output shafts of the cylinders 8 are rotatably connected to the bottom surface of the lowest cylinder 2. The multiple sets of cylinders 8 arranged at an angle can push the cylinder 2 to tilt to one side, making it easier to discharge the river sand in the cylinder 2 from the discharge port.

[0025] In the present application, multiple sets of limiting mechanisms are sleeved on the rotating shaft 5, and the limiting mechanisms include a first limiting body 9 and a second limiting body 10. The first limiting body 9 and the second limiting body 10 are respectively located on the top and bottom surfaces of the filter screen 201. The first limiting body 9 has a conical structure, and the second limiting body 10 has a circular ring structure. The first limiting body 9 and the second limiting body 10 are provided to limit the vertical position of the filter screen 201 and the cylinder 2. The conical structure of the first limiting body 9 facilitates the river sand to remain along the conical surface and will not accumulate on the first limiting body 9.

[0026] In the present application, the stirring assembly 3 includes a connecting rod 301, one end of which is connected to the rotating shaft 5. The connecting rod 301 is provided with multiple groups of stirring rods 302, which are driven to rotate by the rotating shaft 5. The stirring rods 302 can also be provided with a roller brush to facilitate scrubbing the sticky mud and sand on the surface of the river sand.

[0027] In this application, a discharge port is opened on the side wall of the cylinder 2, and a sealing baffle 202 is provided at the discharge port. One end of the sealing baffle 202 is rotatably connected to the discharge port, and the other end of the sealing baffle 202 is clamped with the side wall of the cylinder 2. The sealing baffle 202 and the discharge port can be in sealing contact. When it is necessary to discharge the material, the clamped end of the sealing baffle 202 is opened and the sealing baffle 202 is pulled open.

[0028] like Figure 1 The upper end of the sealing baffle 202 shown in the figure is connected to the side wall of the cylinder 2 by a clip, and the lower end of the sealing baffle 202 is rotatably connected to the side wall of the lower end of the discharge port of the cylinder 2. When the sealing baffle 202 is opened, the sealing baffle 202 is tilted downward, and the sealing baffle 202 is an arc structure adapted to the cylinder 2. The downward tilted sealing baffle 202 can facilitate the river sand to flow out along the inner wall surface of the sealing baffle 202.

[0029] In the present application, a cover 11 is provided on the uppermost cylinder 2 , a feed port 12 and a water inlet 13 are provided on the cover 11 , and a water outlet is provided on the lowermost cylinder 2 .

[0030] Working principle: The river sand to be graded and cleaned is fed into the uppermost cylinder 2 through the feed port 12. At the same time, the driving motor 4 can be used to drive the rotating shaft 5 to rotate, and the rotating shaft 5 drives the stirring assembly 3. At this time, large particles of river sand will be blocked by the upper filter screen 201, and small particles of river sand fall into the lower cylinder 2. The river sand is classified according to particle size through multiple filter screens 201, and then water is injected from the water inlet 13 to allow the water to enter the cylinder 2 to clean the river sand. At the same time, the stirring rod 302 is driven to rotate by the rotating shaft 5 to turn the river sand over, thereby achieving rapid cleaning of the river sand. After cleaning, the clamped end of the sealing baffle 202 is opened, and the sealing baffle 202 is rotated and tilted downward to allow the river sand to flow out along the inner wall surface of the sealing baffle 202.
