Description

Technical Field

[0001] The utility model relates to the technical field of sand and pebble screening devices, in particular to a sand and pebble separator. Background Art

[0002] The existing sand and gravel separator is a device used to effectively separate sand and pebbles. A screen is usually used to separate sand and pebbles. The screen is installed on an inclined frame. When a mixture containing sand and pebbles is conveyed onto the screen, the mixture will roll down along the surface of the screen. The pebbles, due to their larger particle size, will continue to roll on the surface of the screen and be discharged from one end of the screen, while the sand particles can pass through the small holes of the screen, thereby achieving the separation of sand and pebbles.

[0003] However, when it is in use, it does not have a dust suction device to remove dust. During operation, the staff will continue to inhale air containing a large amount of sand, dust, stone powder and other particles. Long-term exposure to this environment can easily cause diseases, seriously affecting the physical health and quality of life of the staff. In addition, a large amount of dust will affect the staff's vision, making it difficult to clearly observe the working status of the sand and gravel separator. The staff may need to check and clean frequently, thereby interrupting the work process and reducing overall work efficiency. Utility Model Content

The upper end of the support rod 5 is fixedly connected to the slide rail 4, which is used to provide a sliding track for the screen plate 18, so that the screen plate 18 can reciprocate therein to achieve screening of sand and pebbles.

[0023] The inner surface of the slide rail 4 is fixedly connected with an electric push rod 17, which is used to provide power for reciprocating motion of the screen plate 18, so that the screen plate 18 can continuously perform screening operations, thereby improving screening efficiency. The other end of the electric push rod 17 is fixedly connected to the side surface of the screen plate 18, and the inner surface of the slide rail 4 is slidably connected with the screen plate 18, which is used to screen sand and pebbles and separate sand and pebbles. The upper surface of the slide rail 4 is fixedly connected with the feed hopper 3 for feeding materials. The upper surface of the feed hopper 3 is fixedly connected with a cover plate 2, and the upper surface of the cover plate 2 is fixedly connected with a handle 1, and the lower surface of the cover plate 2 is fixedly connected with a sealing strip 16. The side surface of the sealing strip 16 is movably connected to the feed hopper 3. The upper surface of the slide rail 4 is fixedly connected with a cover shell 12, which is used to cooperate with the dust collection box 9 to form a relatively closed space to prevent dust generated during the screening process from spreading to the surrounding environment.

[0024] The upper surface of the cover shell 12 is fixedly connected to a dust box 9, which is used to use the negative pressure generated by the air pump 10 to suck the dust generated during the screening process into the dust box 9, thereby purifying the working environment. The front surface of the dust box 9 is movably connected to a sealing cover 22, and a plurality of suction holes 23 are provided on the dust box 9, and the plurality of suction holes 23 are connected to the cover shell 12.

[0025] Working principle: When in use, turn on the motor 8, the motor 8 drives the conveyor roller 20 to start rotating, thereby starting the conveyor belt 19 to run, turn on the air pump 10, and the air pump 10 generates a negative pressure state inside the dust box 9 through the suction head 11, open the cover 2 on the feed hopper 3, and slowly pour the sand and pebble mixture into the feed hopper 3. The sand and pebble mixture will fall evenly on the screen plate 18 under the action of gravity, and the electric push rod 17 starts working, pushing the screen plate 18 to do reciprocating motion in the slide rail 4. The sand and pebble mixture reciprocates on the screen plate 18. Screening starts under movement. During the screening process, due to the aperture design of the sieve plate 18, the sand particles will pass through the sieve holes and fall onto the conveyor belt 19 below, while the larger pebbles will remain on the sieve plate 18 and slide down along the sieve plate 18. The dust generated during screening will be sucked into the interior of the dust box 9 through the suction holes 23 to prevent it from spreading to the outside. The sand that falls on the conveyor belt 19 will be transported backward as the conveyor belt 19 runs. After use, open the sealing cover 22 on the dust box 9 to clean the dust inside the dust box 9.
