Technical Field

[0001] The present application relates to the technical field of sand and gravel separators, and specifically to a sand and gravel separator. Background Art

[0002] The gravel separator, also known as the concrete gravel separator or the concrete gravel separation slurry water recovery equipment, is the core equipment of the concrete recovery system. It is mainly used to clean, separate and recycle the wastewater from the tank truck and the sand and gravel in the residual concrete.

[0003] The existing patent (publication number: CN 221017193 U) has announced a new type of concrete sand and gravel separator, which relates to the field of construction technology. The utility model includes a frame, a feed hopper, a separation cylinder, a sand collecting trough, a stone collecting trough, a water collecting trough and a driving device; the separation cylinder is rotatably arranged on the frame, and includes two fixedly spliced ​​first bar rollers and second bar rollers; the spacing between two adjacent bars on the first bar roller is smaller than the spacing between two adjacent bars on the second bar roller; the feed hopper is fixed on the frame, and its discharge port extends into the first bar roller; the sand collecting trough and the stone collecting trough are arranged side by side and obliquely below the separation cylinder, and the sand collecting trough is located below the first bar roller, and the stone collecting trough is located below the second bar roller. The utility model, through the coordinated design of various structures, can realize the separation of concrete slurry and sand and gravel aggregates, and can further separate large-grained gravel and small-grained sand in the aggregates, thereby improving the separation quality and efficiency of sand and gravel aggregates.

[0004] The above-mentioned sand and gravel separator needs to clean the gravel with larger particles in the drum separately, and the cleaning is laborious, which increases the workload of workers and reduces work efficiency. It is also inconvenient to disassemble and maintain the drum, which reduces the flexibility and practicality of the sand and gravel separator. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides a sand and gravel separator, which has the advantages of avoiding manual cleaning of larger particles of gravel, reducing dependence on manpower, facilitating disassembly and maintenance of the separation structure, reducing the workload of workers, and improving work efficiency. It solves the problem that the existing sand and gravel separator needs to clean the larger particles of gravel in the drum separately, and the cleaning is more laborious, increasing the workload of workers, reducing work efficiency, and is not convenient for disassembly and maintenance of the drum, reducing the flexibility and practicality of the sand and gravel separator.

[0006] To achieve the above object, the present application provides the following technical solution: A sand and gravel separator, including a main body. Inside the main body, three equally spaced sieve plates are slidably connected through empty slots. Inside each sieve plate, a sieve mesh is fixedly connected. On the upper surface of each sieve plate, two side plates are fixedly connected. On the right side surface of the main body, a bracket is fixedly connected. On the upper surface of the bracket, a motor is fixedly connected. Above the motor, a rotating rod is rotatably connected through an output shaft. A connecting plate is rotatably sleeved on the outer circumferential surface of the rotating rod. On the upper surface of the bracket, a fixed seat is fixedly connected. Inside the fixed seat, a sliding frame is slidably connected. On the outer surface of the sliding frame, a fixed rod is fixedly connected. One end of the connecting plate away from the rotating rod is rotatably sleeved on the outer circumferential surface of the fixed rod. On the left side surface of the sliding frame, three positioning seats are fixedly connected. Inside each positioning seat, a control rod is rotatably inserted. A positioning rod is threadedly connected to the outer circumferential surface of the control rod. The outer circumferential surface of the positioning rod is slidably inserted into the inside of the sieve plate respectively.

[0007] Through the above solution, since the existing sand and gravel separator needs to separately clean the larger gravel in the drum, and it is quite laborious during cleaning, increasing the workload of workers, reducing the operation efficiency, and it is not convenient to disassemble and maintain the drum, reducing the flexibility and practicality of the sand and gravel separator. By slidably arranging multiple levels of inclined sieve plates and sieve meshes, it can promote the multi-level separation of sand and gravel and automatically roll and drop the materials, avoiding manual separate cleaning of the larger gravel, and facilitating the disassembly and maintenance of the sieve plates and sieve meshes, reducing the workload of workers and improving the operation efficiency.

[0008] Further, each sieve plate is inclined downward by a certain angle, and the size of the filtering openings of the sieve mesh decreases sequentially from top to bottom.

[0009] Through the above solution, it can promote the separation of sand and gravel of different sizes, and make the sand and gravel flow slowly while passing through the sieve, and automatically drop the materials.

[0010] Further, a limit ring is fixedly sleeved on the outer circumferential surface of the control rod, and the outer circumferential surface of the limit ring is rotatably connected to the inside of the positioning seat.

[0011] Through the above solution, the control rod is restricted to prevent the control rod from sliding and shifting, increasing the stability of the control rod movement.

[0012] Further, a limit block is fixedly connected to the outer circumferential surface of the positioning rod, and the outer surface of the limit block is slidably connected to the positioning seat through an empty slot opened inside the positioning seat.

[0013] Through the above solution, the positioning rod is restricted to prevent the positioning rod from rotating along with the control rod, and promote the positioning rod to always perform longitudinal lifting and lowering to complete the connection of the sieve plate.

[0014] Furthermore, a water collecting tank is provided at the bottom of the main body, and a water outlet is provided at the bottom of the main body.

[0015] Through the above solution, the water in the sand and gravel can be gathered in the water collecting tank and discharged through the water outlet.

[0016] Furthermore, a material guiding frame is fixedly connected to the outer surface of the main body. The material guiding frame is composed of three material guiding plates with different lengths. The three material guiding plates are all inclined downward at a certain angle, and the lengths of the three material guiding plates decrease in turn from top to bottom.

[0017] Through the above solution, the discharging positions of the sand and gravel are different, which is convenient for separately discharging the separated sand and gravel.

[0018] Furthermore, a water supply pipe is fixedly connected to the top end of the main body, and evenly arranged spray heads are fixedly connected to the outer circumferential surface of the water supply pipe.

[0019] Through the above solution, the water supply pipe can be connected to an external water pipe, and the sand and gravel during screening can be rinsed through the spray heads, which is convenient for separating sand and gravel of different specifications and sizes.

[0020] Furthermore, four sliding plates are fixedly connected to the bottom surface of each sieve plate, and the sliding plates are respectively slidably connected to the main body through empty slots provided inside the main body.

[0021] Through the above solution, the sieve plate is always moved horizontally to prevent the sieve plate from slipping out of the main body.

[0022] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0023] This sand and gravel separator, by slidably arranging multiple levels of inclined sieve plates and sieve meshes, enables the sand and gravel to be separated at multiple levels and automatically roll down for discharging, achieving the effects of avoiding manual cleaning of larger crushed stones, facilitating the disassembly and maintenance of the sieve plates and sieve meshes, reducing the labor intensity of workers, and improving the operation efficiency. It solves the problems that the existing sand and gravel separators need to separately clean the larger crushed stones in the drum, which is laborious during cleaning, and it is not convenient to disassemble and maintain the drum, reducing the flexibility and practicality of the sand and gravel separator.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0033] Please refer to Figure 1 , Figure 2 and Figure 3 , a sand and gravel separator in this embodiment includes a body 1. Three equally spaced sieve plates 2 are slidably connected inside the body 1 through empty slots. A sieve mesh 3 is fixedly connected inside each sieve plate 2. Two side plates 4 are fixedly connected to the upper surface of each sieve plate 2. A bracket 5 is fixedly connected to the right side surface of the body 1. A motor 6 is fixedly connected to the upper surface of the bracket 5. A rotating rod 7 is rotatably connected above the motor 6 through an output shaft. A connecting plate 8 is rotatably sleeved on the outer circumferential surface of the rotating rod 7. A fixed seat 9 is fixedly connected to the upper surface of the bracket 5. A sliding frame 10 is slidably connected inside the fixed seat 9. A fixed rod 11 is fixedly connected to the outer surface of the sliding frame 10. One end of the connecting plate 8 away from the rotating rod 7 is rotatably sleeved on the outer circumferential surface of the fixed rod 11. Three positioning seats 12 are fixedly connected to the left side surface of the sliding frame 10. A control rod 13 is rotatably inserted into each positioning seat 12. A positioning rod 14 is threadedly connected to the outer circumferential surface of the control rod 13. The outer circumferential surface of the positioning rod 14 is slidably inserted into the inside of the sieve plate 2 respectively.

[0034] Please refer to Figure 1 , Figure 4 and Figure 5, each sieve plate 2 is inclined downward at a certain angle, and the size of the filtering openings of the sieve mesh 3 decreases successively from top to bottom, prompting the separation of sands and gravels of different sizes and enabling the sands and gravels to flow slowly while being sieved, for automatic feeding.

[0035] Please refer to Figure 3 , a limiting ring 15 is fixedly sleeved on the outer circumferential surface of the control rod 13, and the outer circumferential surface of the limiting ring 15 is rotatably connected to the inside of the positioning seat 12 to limit the control rod 13 and prevent the control rod 13 from sliding and shifting, thereby increasing the stability of the movement of the control rod 13.

[0036] Please refer to Figure 3 , a limiting block 16 is fixedly connected to the outer circumferential surface of the positioning rod 14, and the outer surface of the limiting block 16 is slidably connected to the positioning seat 12 through an empty groove formed inside the positioning seat 12 to limit the positioning rod 14 and prevent the positioning rod 14 from rotating following the control rod 13, prompting the positioning rod 14 to always perform vertical lifting and lowering to complete the connection of the sieve plate 2.

[0037] Please refer to Figure 1 and Figure 5 , a water collecting tank 17 is opened at the bottom of the main body 1, and a water outlet 18 is opened at the bottom of the main body 1, enabling the water in the sands and gravels to converge in the water collecting tank 17 and be discharged through the water outlet 18.

[0038] Please refer to Figure 1 and Figure 4 , a material guiding frame 19 is fixedly connected to the outer surface of the main body 1. The material guiding frame 19 is composed of three material guiding plates with different lengths. All three material guiding plates are inclined downward at a certain angle, and the lengths of the three material guiding plates decrease successively from top to bottom, prompting the discharging positions of the sands and gravels to be different and facilitating the separate discharging of the separated sands and gravels.

[0039] Please refer to Figure 1 and Figure 5 , a water supply pipe 20 is fixedly connected to the top end of the main body 1. Nozzles arranged at equal intervals are fixedly connected to the outer circumferential surface of the water supply pipe 20. The water supply pipe 20 can be connected to an external water pipe, and the sands and gravels being sieved can be rinsed through the nozzles, facilitating the separation of sands and gravels of different specifications and sizes.

[0040] Please refer to Figure 1 , Figure 5 and Figure 6 , four sliding plates 21 are fixedly connected to the bottom surface of each sieve plate 2. The sliding plates 21 are respectively slidably connected to the main body 1 through empty grooves formed inside the main body 1, prompting the sieve plate 2 to always perform lateral movement and preventing the sieve plate 2 from slipping out of the main body 1.

[0041] A sand and gravel separator in this embodiment slides and arranges multiple levels of inclined sieve plates 2 and sieve meshes 3, which enables the sand and gravel to be separated at multiple levels and automatically roll down for discharging. This achieves the effect of avoiding manual cleaning of larger crushed stones, facilitating the disassembly and maintenance of the sieve plates 2 and sieve meshes 3, reducing the labor burden of workers, and improving the operation efficiency. It solves the problems of the existing sand and gravel separator that requires separate cleaning of larger crushed stones in the drum, which is laborious during cleaning, and is not convenient for disassembling and maintaining the drum, reducing the flexibility and practicality of the sand and gravel separator.

[0042] It should be noted that a knob is provided at the top of the control rod 13, which facilitates the manipulation of the control rod 13 through the knob.

[0043] The working principle of the above embodiment is as follows:

[0044] When sand and gravel separation operation is required, the sand and gravel are poured onto the topmost sieve mesh 3. The motor 6 is started as the power, and the output shaft drives the rotating rod 7 to rotate. The rotating rod 7 drives the sliding frame 10 to reciprocate through the connecting plate 8 and the fixed rod 11. The sliding frame 10 drives the positioning rod 14 to reciprocate through the positioning seat 12. The positioning rod 14 then drives the sieve plate 2 to vibrate, assisting the sand and gravel to pass through the sieve, promoting the separation of sand and gravel of different specifications. The smaller-sized sand and gravel will fall successively. During the sand and gravel separation process, it will slowly flow forward under the action of the downward inclination of the sieve plate 2. Finally, the separated sand and gravel will fall on different guide plates of the guide frame 19 respectively. Containers for collecting sand and gravel can be placed in advance under each guide plate, so that the separated sand and gravel can fall into different containers through different guide plates. The water supply pipe 20 can be connected to an external water pipe, and the sand and gravel during screening can be rinsed through the nozzle, facilitating the separation of sand and gravel of different specifications. The water in the sand and gravel will flow downward and converge in the water collecting tank 17, and the water will be discharged through the water outlet 18. When the sieve plate 2 and the sieve mesh 3 need to be disassembled and maintained, the corresponding control rod 13 can be rotated to drive the positioning rod 14 to move upward, so that the positioning rod 14 is removed from the inside of the corresponding sieve plate 2, and then the sieve plate 2 can be removed from the main body 1.
