Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing devices, in particular to an anti-clogging concrete sand and gravel separator. Background Art

[0002] Concrete sand and gravel separators are widely used in washing, grading, removing impurities, and washing fine-grained and coarse-grained materials in the highway, hydropower, construction and other industries. They are particularly suitable for sand and gravel used in construction and road construction. If concrete is not treated and discharged into the river at will, it will cause pollution and waste a lot of concrete materials. At the same time, if the remaining concrete materials after use are directly discarded, it will not only waste resources but also be detrimental to environmental protection. The existing patent number CN211802233U proposes a concrete sand and gravel separator, in which concrete sand and gravel are poured into a feed trough, and then the concrete sand and gravel flow from the inside of the feed trough into the inside of the separation net, the motor starts to rotate, driving the rotation, and then the separation net fixedly connected to the inner ring of the outer gear ring starts to rotate, and the rotating blades inside the separation net start to rotate, and then the concrete sand and gravel inside the separation net are separated by the separation net, and the smaller sand and gravel are drilled out from the through holes on the side of the separation net, and the larger sand and gravel roll out from the left end of the separation net due to gravity. The high-pressure nozzle can flush the gravel in the mesh of the separation net to prevent the separation net from being blocked, and then the smaller gravel rolls out from the left outlet of the gravel collecting net due to gravity, and the larger stones roll into the inside of the stone collecting trough, and then roll out from the side outlet of the stone collecting trough, but the device may cause part of the sand to roll out with the stones during the separation process, resulting in waste of sand.

The separation barrel 104 can be assisted by the feeding component, or it can be directly fed manually. The rotation of the screening barrel 104 is controlled by the rotating control component to separate the sand and gravel. During the separation process, the leakage holes 110 and the filter holes on the screening barrel 104 are staggered, so that the sand thrown out during the separation process hits the inner wall of the mounting hole 102, and slides to the leakage holes 110 by gravity and flows out. The staff can collect it through the recovery box. This arrangement can prevent the screening barrel 104 from directly throwing out the sand and splashing out due to the centrifugal force during the high-speed rotation, which is not conducive to subsequent cleaning. In addition, the cover plate 101 can be set to prevent the sand and gravel from being thrown out due to excessive speed during the separation process. The cover plate 101 can be opened. A slot is opened on the working box 100, and a handle is set on the cover plate 101. The cover plate 101 can be pulled out from the working box 100 by pulling the handle, so that the gravel rolls off the discharge end of the screening barrel 104.

The motor frame 106 is provided to facilitate the installation of the driving motor 107. The driving motor 107 is started, and the driving motor 107 drives the rotating shaft 108 to rotate, thereby driving the driving gear 109 to rotate. Since the driving gear 109 and the driven gear 105 are meshed with each other, when the driving gear 109 rotates, it drives the driven gear 105 to rotate, thereby driving the screening barrel 104 to rotate.
