Abstract
Description
Technical Field
[0001] This utility model relates to the field of sand and gravel separation technology, and in particular to a sand and gravel separation device for building construction. Background Technology
[0002] In the construction industry, sand and gravel separation is a crucial step in material recycling and reuse. Currently, traditional sand and gravel separation relies heavily on manual sorting or simple screening equipment, resulting in low efficiency, high labor costs, and an inability to meet the demands of large-scale construction. Existing screening equipment commonly suffers from easily clogged filters, requiring frequent shutdowns for cleaning and severely impacting operational continuity. Simultaneously, sand adhering to the stone surface is difficult to completely separate, leading to insufficient separation purity and affecting the quality of recycled materials for secondary use. Furthermore, the cleaning components of most equipment lack stable support structures, making them prone to rapid wear due to movement and vibration, thus shortening equipment lifespan. Moreover, sand and gravel recycling often involves mixed collection, resulting in significant resource waste and failing to meet the requirements of green construction development. Utility Model Content

A turntable is fixedly connected to the end of the auger away from the motor. An eccentric block is fixedly connected to the side surface of the turntable via a push rod. A sliding chute is movably connected to the side surface of the push rod. A cleaning brush is fixedly connected to the side surface of the sliding chute, and a slider is fixedly connected to the side surface of the sliding chute. Through these components, the auger, driven by a motor, transports sand and gravel, and in conjunction with the filter screen, achieves automatic sand and gravel separation, significantly improving separation efficiency. A cleaning mechanism is synchronously installed in the device. When the auger rotates, it drives the cleaning brush to move along the filter screen, which can promptly remove blockages on the filter screen surface, ensuring smooth screening and reducing equipment downtime for cleaning. The eccentric block vibrates as it impacts the impact plate as the turntable rotates, effectively shaking off sand adhering to the stone surface and improving separation purity.

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0016] Reference Figure 1-4 This utility model embodiment provides a sand and gravel separation device for construction, which includes: a separation cylinder 3, a filter screen 6 fixedly connected to the side surface of the separation cylinder 3, a motor 9 fixedly connected to the side surface of the separation cylinder 3, and an auger 15 fixedly connected to the output end of the motor 9;
[0017] Specifically, after the sand and gravel are put into the separation cylinder 3, the motor 9 drives the auger 15 to rotate, so that the sand and gravel can be transported along the separation cylinder 3, and when passing through the filter screen 6, the sand will fall through the filter screen 6 and be separated from the stone. An impact plate 14 is fixedly connected to the side surface of the separator 3. A turntable 12 is fixedly connected to the end of the auger 15 away from the motor 9. The side surface of the turntable 12 is rotatably connected to the separator 3. An eccentric block 13 is fixedly connected to the side surface of the turntable 12 via a push rod 17. A sliding chute 11 is movably connected to the side surface of the push rod 17. The side surface of the sliding chute 11 is slidably connected to the separator 3. A cleaning brush 10 is fixedly connected to the side surface of the sliding chute 11. The side surface of the cleaning brush 10 is in contact with the filter screen 6. A slider 16 is fixedly connected to the side surface of the sliding chute 11. The side surface of the slider 16 is slidably connected to the separator 3.
[0018] Specifically, as the auger 15 rotates, it drives the turntable 12 outside the separation cylinder 3 to rotate. Through the push rod 17 on the turntable 12, the sliding plate 11 can slide along the arc-shaped sliding groove on the separation cylinder 3 under the drive of the slider 16, thereby driving the cleaning brush 10 to move along the outer wall of the separation cylinder 3 and cleaning the filter screen 6 with the cleaning brush 10 to prevent the filter screen 6 from clogging. The push rod 17 is also equipped with an eccentric block 13. As the turntable 12 rotates, the eccentric block 13 will hit the impact plate 14 on the separation cylinder 3, thereby causing the separation cylinder 3 to vibrate, which makes it easier to shake off the sand attached to the surface of the stone and improve the separation effect.
[0019] A feed inlet 7 is fixedly connected to the side surface of the separator 3, a discharge outlet 8 is fixedly connected to the side surface of the separator 3, a support 2 is fixedly connected to the side surface of the separator 3, a base plate 1 is fixedly connected to the lower surface of the support 2, a storage box 4 is placed on the upper surface of the base plate 1, the storage box 4 is located below the filter screen 6, a recycling box 5 is placed on the upper surface of the base plate 1, the recycling box 5 is located below the discharge outlet 8, and a slider 2 18 is fixedly connected to the end of the cleaning brush 10 away from the slide plate 11, and the side surface of the slider 2 18 is slidably connected to the support 2.
[0020] Specifically, the separating cylinder 3 is fixed to the base plate 1 by the bracket 2, and the base plate 1 also has a collection box 4 and a recycling box 5. Sand and gravel are poured into the separating cylinder 3 through the feed port 7 and screened by the filter screen 6. The sand will fall into the collection box 4 through the filter screen 6, while the stone will continue to be transported by the auger 15 until it is discharged from the discharge port 8 and falls into the recycling box 5. The end of the cleaning brush 10 is equipped with a slider 2 18, and when the cleaning brush 10 moves, the slider 2 18 slides along the bracket 2 to provide support for the cleaning brush 10 and improve the service life of the cleaning brush 10.
[0021] Working Principle: First, sand and gravel are poured into the separation cylinder 3 through the inlet 7, which is fixed to the base plate 1 by the bracket 2. After starting the motor 9, its output end drives the auger 15 to rotate, causing the sand and gravel to be transported along the inside of the separation cylinder 3. During the transportation process, when the sand and gravel pass through the filter screen 6, the sand falls into the collection box 4 below, achieving sand and gravel separation. At the same time, the rotation of the auger 15 drives the turntable 12 outside the separation cylinder 3 to rotate synchronously. The turntable 12 pushes the sliding plate 11 through the push rod 17, causing the sliding plate 11 to slide along the arc-shaped sliding groove of the separation cylinder 3 under the action of the slider 16, thereby driving the cleaning brush 10 to move along the outer wall of the filter screen 6, effectively preventing the filter screen 6 from clogging. When the eccentric block 13 on the push rod 17 rotates with the turntable 12, it hits the impact plate 14, causing the separation cylinder 3 to vibrate and shake off the sand attached to the surface of the stone, improving the separation effect. Finally, the stone is transported to the outlet 8 by the auger 15 and falls into the recycling box 5. The slider 18 at the end of the cleaning brush 10 slides along the bracket 2 to provide support and extend its service life.
[0022] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
