Abstract
Description
Technical Field
[0001] This utility model relates to the field of sand pumps, specifically a rotatable telescopic multi-angle sand suction combination arm for a sand pump. Background Technology
[0002] Sand dredging pumps are used for dredging rivers, lakes, and reservoirs to keep water bodies clean and unobstructed; for land reclamation in coastal areas by extracting sand from the seabed; and for the maintenance of ports and waterways by clearing sediment from the bottom of waterways to ensure the depth and width of the waterways.
[0003] In river dredging projects, sand pumps are widely used. However, sand pumps need to be used in conjunction with suction arms. Currently, the suction arms of sand pumps are difficult to rotate and extend, making it impossible to flexibly reach every corner of the river. This results in some areas of silt being difficult to remove effectively, seriously affecting the dredging effect of the river. Therefore, those skilled in the art have provided a rotatable and telescopic multi-angle suction arm combination for sand pumps to solve the problems mentioned in the background art.

[0022] Please see Figures 1-4In this embodiment of the utility model, the rotatable telescopic multi-angle sand suction combination arm of the sand pump includes a support base 1, a drainage cover 2 fixedly connected to the bottom surface of the support base 1, a first bearing 4 fixedly embedded in the upper surface of the support base 1, a rotating tube 9 fixedly connected to the inner ring of the first bearing 4, a drive cover 3 fixedly installed on the upper surface of the support base 1, a drive motor 8 fixedly installed on the upper surface of the drive cover 3, a drive shaft 7 fixedly installed at the output end of the drive motor 8, a drive gear 6 fixedly installed at the bottom end of the drive shaft 7, an annular gear disk 5 fixedly connected to the outer surface of the rotating tube 9, and the top end of the rotating tube 9... A support pipe 10 is fixedly connected, and a lower annular plate 15 is fixedly connected to the outer surface of the support pipe 10. Multiple electric hydraulic push rods 11 are fixedly installed on the upper surface of the lower annular plate 15. A sliding sand suction pipe 13 is slidably connected to the inner ring of the support pipe 10. A telescopic hose 14 is fixedly connected to the bottom end of the sliding sand suction pipe 13. The outer surface of the bottom end of the telescopic hose 14 is fixedly connected to the inner ring of the support pipe 10. A filter screen 17 is fixedly connected to the bottom end of the sliding sand suction pipe 13. The filter screen 17 is used to suck up sand and can filter out larger impurities, allowing only sand and smaller particles to pass through.
[0023] As a further improvement of this utility model: multiple reinforcing blocks 16 are fixedly connected to the outer surface of the support tube 10. The side of each reinforcing block 16 that is far apart from each other is fixedly installed to the outer surface of each electric hydraulic push rod 11. A second bearing 19 is fixedly embedded in the upper surface of the drive cover 3. The inner ring of the second bearing 19 is fixedly connected to the outer surface of the rotating tube 9. A bearing ring 18 is fixedly embedded in the upper surface of the drive cover 3. The inner ring of the bearing ring 18 is fixedly connected to the outer surface of the drive shaft 7. By fixing multiple reinforcing blocks 16 to the electric hydraulic push rods 11, the connection strength between the support tube 10 and the electric hydraulic push rods 11 is enhanced, and the structural stability of the entire sand suction combination arm is improved. The setting of the first bearing 4 can make the rotating tube 9 more stable when rotating. The setting of the bearing ring 18 can also make the drive shaft 7 rotate stably.
[0024] As a further embodiment of this utility model: the bottom end of the drainage cover 2 is fixedly connected to a connecting plate 20, and the bottom surface of the connecting plate 20 is provided with multiple connecting holes 21. The left end of the drive gear 6 meshes with the right end of the ring gear disk 5, which is located inside the drive cover 3. The outer surface of the sliding sand suction pipe 13 is fixedly connected to an upper ring plate 12. The telescopic end of each electric hydraulic push rod 11 is fixedly installed with the bottom surface of the upper ring plate 12. Through the setting of the connecting plate 20 and multiple connecting holes 21, it can be connected and installed with a sand pump, improving the flexibility of connection and installation. The meshing of the drive gear 6 and the ring gear disk 5 will better transmit power. With the setting of the upper ring plate 12 and the electric hydraulic push rod 11, the electric hydraulic push rod 11 can drive the sliding sand suction pipe 13 to move up and down, providing power for its lifting and lowering movement.
[0025] The working principle of this utility model is as follows: First, the entire sand suction assembly arm is connected to the sand pump through the connecting plate 20 and multiple connecting holes 21, and by using bolts and other connecting parts. When the angle of sand suction is adjusted, the drive motor 8 is started, which can drive the drive shaft 7 and drive gear 6 to rotate and mesh with the ring gear disk 5. This can drive the rotating tube 9, support tube 10 and sliding sand suction tube 13 to rotate, so that the sliding sand suction tube 13 can achieve the purpose of multi-angle sand suction.
[0026] When the sliding sand suction pipe 13 is extended or retracted, the electric hydraulic push rod 11 is controlled to extend or retract, which can push the upper annular plate 12 and the sliding sand suction pipe 13 to slide within the inner ring of the support pipe 10. The bottom end of the sliding sand suction pipe 13 is connected to the inside of the support pipe 10 through the telescopic hose 14, which can ensure the sealing of the connection during extension and retraction, so that the sliding sand suction pipe 13 can extend or retract within a certain range, thereby adjusting the depth and position of sand suction.
