[0029] Embodiment 1

[0030] A multifunctional grading and de-sludging hopper for processing construction waste sand, as Figures 1 to 4 shown, includes a tank body 2 supported by a fixing frame 1. Inside the tank body 2, an inner hopper 4, an outer hopper 5 and a sludge chamber 6 are sequentially arranged from the center outwards. The inner hopper 4, the outer hopper 5 and the sludge chamber 6 are connected by an overflow pipe 7. A feeding port 3 is arranged at the top end of the tank body 2, and the bottom end of the feeding port 3 is connected to the inner hopper 4. A buffer plate 8 is arranged at the bottom end of the feeding port 3, and the buffer plate 8 is conical. A gate plate 9 is arranged between the bottom ends of the outer hopper 5 and the inner hopper 4. The top end of the gate plate 9 is connected to an electric telescopic rod. A water outlet 11 is arranged on the side wall at the bottom end of the sludge chamber 6, and a filter plate 10 is installed on the inner wall of the sludge chamber 6. The bottom end of the inner hopper 4 is connected to a sand outlet pipe 20 through a sand outlet 12. A spiral blade 21 is rotatably connected to the inner wall of the sand outlet pipe 20. A connecting piece 14 is connected to the inner wall of the sand outlet 12. The top end of the connecting piece 14 is rotatably connected to a water adding pipe 15. A driven gear 13 is rotatably connected to the middle section of the sand outlet 12. The inner wall of the driven gear 13 is connected to the water adding pipe 15 through a connecting frame. The top end of the connecting frame is connected to a stirring rod 16. The connecting piece 14 is communicated with a water delivery pump 19 through a hose. The water inlet end of the water delivery pump 19 is connected to a water storage container. A driving mechanism for driving the driven gear 13 and the spiral blade 21 is arranged at the bottom end of the fixing frame 1.

[0031] When dewatering construction waste sand, the waste sand is put into the inner hopper 4 from the feeding port 3. At the same time, the water pump 19 injects water into the inner hopper 4 through the connecting piece 14 and the water supply pipe 15. When the waste sand falls from the feeding port 3, it is blocked and buffered by the buffer plate 8 and dispersed around, effectively slowing down the impact speed of the waste sand, avoiding local accumulation of the waste sand in the inner hopper 4, and improving the dewatering efficiency. The water injected into the inner hopper 4 floats the waste sand. The coarse sand settles by gravity and accumulates at the sand outlet 12. The soil and part of the fine sand overflow into the outer hopper 5 with the water through the overflow pipe 7. The fine sand settles in the outer hopper 5, and the soil overflows into the sludge chamber 6 with the water. The filter plate 10 in the sludge chamber 6 filters the muddy water, and the soil is collected in the sludge chamber 6. The water filtered by the filter plate 10 is discharged through the water outlet 11; during the dewatering process, the driving mechanism drives the driven gear 13 to rotate, driving the water supply pipe 15 and the stirring rod 16 to rotate, so that the water injected into the inner hopper 4 rotates in a spiral manner. The coarse sand deposits, and the fine sand is difficult to deposit and overflows into the outer hopper 5 together with the water, realizing the effective separation of coarse sand particles and fine sand particles; after dewatering a certain amount of waste sand, the driving mechanism drives the spiral blade 21 to rotate, and discharges the coarse sand at the bottom of the inner hopper 4 through the sand discharge pipe 20. After the discharge of the coarse sand at the bottom of the inner hopper 4 is completed, the electric telescopic rod drives the gate plate 9 to rise, and the fine sand at the bottom of the outer hopper 5 slides into the bottom of the inner hopper 4 for discharging. During the discharging process, the stirring rod 16 can disperse the sand, making the discharging smoother.

[0032] By setting the stirring rod 16, the sand discharge pipe 20 and the spiral blade 21, after dewatering a certain amount of waste sand, the driving mechanism drives the spiral blade 21 to rotate, and discharges the coarse sand at the bottom of the inner hopper 4 through the sand discharge pipe 20. At the same time, during the discharging process, the stirring rod 16 can disperse the sand, making the discharging smoother and avoiding the accumulation of sand in the sand discharge pipe 20 and difficult discharging.

[0033] By setting the buffer plate 8, when the waste sand enters the inner hopper 4, the waste sand is blocked and buffered by the buffer plate 8 and dispersed around, effectively slowing down the impact speed of the waste sand, avoiding local accumulation of the waste sand in the inner hopper 4, and improving the dewatering efficiency.

[0034] Embodiment 2

On the basis of Embodiment 1, the following improvements are made, such as Figure 5 、 Figure 6As shown, the driving mechanism includes a motor 18 installed on a fixed frame 1 and a second driven bevel gear 27 connected to the rotating shaft of a spiral blade 21. The output shaft of the motor 18 is connected with a driving gear 17. The driving gear 17 is in transmission engagement with a driven gear 13. An outer wall of the output shaft of the motor 18 is fixed with a first driving bevel gear 22. A first driven bevel gear 23 is in transmission engagement with one side of the first driving bevel gear 22. A first transmission bevel gear 24 is connected to one side of the first driven bevel gear 23 through a coupling 28. A second transmission bevel gear 25 is in transmission engagement with one side of the first transmission bevel gear 24. The other end of the rotating shaft of the second transmission bevel gear 25 is connected with a second driving bevel gear 26. The second driving bevel gear 26 is in transmission engagement with the second driven bevel gear 27. The coupling 28 includes a housing 29, a first half shaft 30 and a second half shaft 31 which are rotatably connected to two ends of the inner wall of the housing 29. One end of the first half shaft 30 is connected with the first driven bevel gear 23. One end of the second half shaft 31 is connected with the first transmission bevel gear 24. A spline 32 is slidably connected to an inner wall of the first half shaft 30. A groove which is in limit fit with the spline 32 is formed at one end of the second half shaft 31. An electromagnet 33 is fixed to the inner wall of the first half shaft 30. A permanent magnet opposite to the electromagnet 33 is fixed to an outer wall of one end of the spline 32.

[0036] When driving the driven gear 13 to rotate, the motor 18 drives the driving gear 17 to rotate. At the same time, the first driving bevel gear 22 drives the first driven bevel gear 23 to rotate. At this time, the electromagnet 33 adsorbs the permanent magnet, the spline 32 retracts into the first half shaft 30, the connection between the first half shaft 30 and the second half shaft 31 is disconnected, and the first transmission bevel gear 24 will not rotate with the first driven bevel gear 23. When discharging, the electromagnet 33 repels the permanent magnet by magnetic force, the spline 32 inserts into the second half shaft 31, and the first half shaft 30 is connected with the second half shaft 31. At this time, when the motor 18 drives the driving gear 17 to rotate, the first driving bevel gear 22 drives the first driven bevel gear 23 to rotate, the first transmission bevel gear 24 rotates with the first driven bevel gear 23, the transmission engagement between the first transmission bevel gear 24 and the second transmission bevel gear 25 drives the second driving bevel gear 26 to rotate, and the second driving bevel gear 26 drives the second driven bevel gear 27 to rotate, so that the spiral blade 21 rotates.

[0037] By arranging the driving mechanism, the motor 18, as a power source, is used to drive the driven gear 13 and the spiral blade 21 to rotate, reducing the arrangement of power sources and making the structure of the device more compact.

[0038] Working principle: When de-sludging construction waste sand, the waste sand is put into the inner hopper 4 from the feeding port 3. At the same time, the water pump 19 injects water into the inner hopper 4 through the connecting piece 14 and the water adding pipe 15. When the waste sand falls from the feeding port 3, it is blocked and buffered by the buffer plate 8 and disperses around, effectively slowing down the impact speed of the waste sand, avoiding local accumulation of the waste sand in the inner hopper 4, and improving the de-sludging efficiency. The water injected into the inner hopper 4 floats the waste sand. The coarse sand settles under gravity and accumulates at the sand outlet 12. The mud and part of the fine sand overflow into the outer hopper 5 with the water from the overflow pipe 7. The fine sand settles in the outer hopper 5, and the mud overflows into the sludge chamber 6 with the water. The filter plate 10 in the sludge chamber 6 filters the muddy water, and the mud is collected in the sludge chamber 6. The water filtered by the filter plate 10 is discharged through the water outlet 11; during the de-sludging process, the motor 18 drives the driving gear 17 to rotate, the driving gear 17 drives the driven gear 13 to rotate, driving the water adding pipe 15 and the stirring rod 16 to rotate, which can make the water injected into the inner hopper 4 rotate in a spiral. The coarse sand deposits, and the fine sand is difficult to deposit and overflows into the outer hopper 5 together with the water, realizing the effective separation of coarse sand particles and fine sand particles. At the same time, the first driving bevel gear 22 drives the first driven bevel gear 23 to rotate. At this time, the electromagnet 33 adsorbs the permanent magnet, the spline 32 retracts into the first half shaft 30, and the connection between the first half shaft 30 and the second half shaft 31 is disconnected. The first driving bevel gear 24 will not rotate with the first driven bevel gear 23. After de-sludging a certain amount of waste sand, the electromagnet 33 repels the permanent magnet magnetically, the spline 32 inserts into the second half shaft 31, and the first half shaft 30 is connected to the second half shaft 31. At this time, when the motor 18 drives the driving gear 17 to rotate, the first driving bevel gear 22 drives the first driven bevel gear 23 to rotate, and the first driving bevel gear 24 rotates with the first driven bevel gear 23. The meshing transmission between the first driving bevel gear 24 and the second driving bevel gear 25 drives the second driving bevel gear 26 to rotate, and the second driving bevel gear 26 drives the second driven bevel gear 27 to rotate, making the spiral blade 21 rotate, and discharging the coarse sand at the bottom of the inner hopper 4 through the sand outlet pipe 20. After the discharging of the coarse sand at the bottom of the inner hopper 4 is completed, the electric telescopic rod drives the gate plate 9 to rise, and the fine sand at the bottom of the outer hopper 5 slides into the bottom of the inner hopper 4 for discharging. During the discharging process, the stirring rod 16 can disperse the sand to make the discharging smoother.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
