Description

Technical Field

[0001] The present application relates to the technical field of river management, and in particular to a dredged soil transfer device. Background Art

[0002] Due to long-term sedimentation, the river channel will have a reduced depth and narrowed width, which will affect the passage of ships. In this case, the river channel needs to be dredged and desilted. In addition, as the river channel becomes busier, the demand for the river channel's traffic capacity will also increase. In this case, dredging can also be carried out proactively to widen the river channel. Dredging projects use a cutter suction dredger, which uses the rotary motion of the auger installed at the front end of the auger bridge to dig and break the ground. The excavated mud and water are pumped above the water surface by a mud pump, and then the mud is moved to the shore through transfer equipment.

[0003] The utility model patent with the existing announcement number CN219729479U discloses a dredged soil transfer device for river dredging, including a screw feeder, a feed hopper is fixedly installed at the feed end on one side of the top of the screw feeder, positioning shafts are fixedly installed at both ends of the feed hopper, a feed pipe is arranged in the feed hopper, bearing seats are fixedly installed at the bottom of both ends of the feed pipe, one end of the positioning shaft is fixedly connected to the rotating circle of the bearing seat, a feed hopper is fixedly installed on the top of the feed pipe, and cylinders are fixedly installed on both sides of the feed hopper. The principle of the transfer device is to transport soil through a screw feeder.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the river channel is long and the height difference between the river bank and the water surface is also different. When the height difference is too large, the transfer equipment is difficult to install and use at one end of the ship, and the geological conditions on the shore are different. Some locations are difficult to receive silt, which is inconvenient. Utility Model Content

[0005] The present application provides a dredged soil transfer device, which is provided with two sections and can adjust the angles in the vertical and horizontal directions. It has the advantages of being located at one end on the ship for easy installation and the output position on the shore being adjustable.

[0006] The present application provides a dredged soil transfer device, which adopts the following technical solution:

[0007] A dredged soil transfer device includes a screw conveyor 1 and a screw conveyor 2. The feed end of the screw conveyor 2 is connected below the discharge end of the screw conveyor 1. The bottom of the screw conveyor 1 is rotatably connected to a turntable, and a support plate is fixed to the turntable. A hinge seat is fixed on the screw conveyor 2, and the bottom end of the support plate is hinged to the hinge seat.

[0008] Through the above technical solution, the turntable is used to realize the horizontal angle swing of the screw conveyor 2, and the support plate and the hinge seat are used to realize the vertical angle swing of the screw conveyor 2. By setting up two screw conveyors, the screw conveyor 1 connected to the ship can be placed as flat as possible, which is convenient and safer to install. The screw conveyor 2 can adjust the vertical and horizontal angles, and the output position on the shore can be flexibly adjusted to avoid the position that cannot receive mud, which is convenient for use.

[0009] Preferably, two support plates are provided, and the two support plates are symmetrically distributed about the circumference of the turntable.

[0010] Through the above technical solution, by setting two support plates, the force is made more balanced and the supporting force of the screw conveyor is improved.

[0011] Preferably, a rotating groove is provided at the bottom of the screw conveyor 1, and the rotating disk is located in the rotating groove.

[0012] Through the above technical solution, the turntable can be separated from the screw conveyor by moving downward, so that it is easy to disassemble.

[0013] Preferably, the bottom surface of the screw conveyor 1 is rotatably connected to a limiting plate, and the limiting plate abuts against the bottom surface of the turntable.

[0014] Through the above technical solution, the limit plate prevents the turntable from separating from the turntable, thereby improving the stability of the transfer equipment during operation.

[0015] Preferably, the limiting plate is a metal plate, an annular groove is provided on the bottom surface of the turntable, a hemispherical block is fixed on the top surface of the limiting plate, and the hemispherical block is embedded in the annular groove.

[0016] Through the above technical solution, when the turntable rotates, the hemispherical block slides relatively in the annular groove, and the annular groove prevents the hemispherical block from spontaneously detaching and prevents the limit plate from spontaneously rotating. The limit plate made of metal sheet material is elastic, and personnel can apply force to the limit plate to deform it, so that the hemispherical block is detached from the annular groove, and then the limit plate is rotated outside the turntable. At this time, the turntable can be separated from the rotating groove, which is convenient for disassembly and assembly.

[0018] Through the above technical solution, a positioning bolt is screwed into the support plate, and the end of the positioning bolt is inserted into the aligned positioning hole, thereby limiting the relative rotation between the support plate and the hinge seat, thereby improving the stability of the transfer equipment during operation.

[0019] Preferably, the second screw conveyor is rotatably connected to a support foot, the support foot is threadedly connected to a second positioning bolt, and a plurality of second positioning holes for inserting the second positioning bolts are circumferentially provided on the second screw conveyor.

[0020] Through the above technical solution, by screwing the second positioning bolt into the support leg and inserting the end of the second positioning bolt into the aligned second positioning hole, the relative rotation between the support leg and the screw conveyor is limited, so that the support leg will not swing at an arbitrary angle, thereby improving stability.

[0021] Preferably, a support plate is fixed to the lower end of the support leg, and a pointed cone is fixed to the bottom end of the support plate.

[0022] Through the above technical solution, the pointed cone is used to be inserted into the ground to prevent the lower end of the support leg from moving, and the support plate is used to contact the ground for support. Through the combination of the support plate and the pointed cone, the stability of the support leg can be significantly improved.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up two screw conveyors, the screw conveyor 1 connected to the ship can be placed flat as much as possible, which is convenient and safer to install.

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] Reference Figure 1 A dredged soil transfer equipment includes a screw conveyor 1 and a screw conveyor 2. The feed end of the screw conveyor 1 is located on a ship, the feed end of the screw conveyor 1 is equipped with a feed hopper 11, the discharge end of the screw conveyor 1 is equipped with a discharge hopper 12, the feed end of the screw conveyor 2 is connected below the discharge end of the screw conveyor 1, the feed end of the screw conveyor 2 is equipped with a feed hopper 21, the feed hopper 21 is flared to increase the scope of receiving soil, the discharge end of the screw conveyor 2 is located on the shore, and the discharge end of the screw conveyor 2 is equipped with a discharge hopper 22. The screw conveyor 1 and the screw conveyor 2 are driven by a motor to rotate the internal spiral blades to transport soil, which is a prior art.

[0033] Reference Figure 1 and Figure 2 A rotating groove 13 is provided at the bottom of the screw conveyor 1 near the discharge hopper 12, and a turntable 3 is rotatably connected in the rotating groove 13. The turntable 3 is placed in the rotating groove 13, and the turntable 3 can be separated from the screw conveyor 1 by moving downward. The turntable 3 is fixed with a support plate 4, and two support plates 4 are provided. The two support plates 4 are symmetrically distributed about the circumference of the turntable 3. A hinge seat 23 is fixed on the screw conveyor 2, and the hinge seat 23 is close to the feed hopper 11. The bottom ends of the two support plates 4 are hinged to the hinge seat 23. By providing two support plates 4, the force is more balanced, and the support force for the screw conveyor 1 is improved.

[0034] The turntable 3 is used to realize the horizontal angular swing of the screw conveyor 2, and the support plate 4 and the hinge seat 23 are used to realize the vertical angular swing of the screw conveyor 2.

[0035] The bottom surface of the screw conveyor 1 is rotatably connected with a limiting piece 14, and two limiting pieces 14 are symmetrically arranged about the circumference of the turntable 3, and the limiting pieces 14 abut the bottom surface of the turntable 3. The limiting piece 14 is a metal sheet, and an annular groove 31 is provided on the bottom surface of the turntable 3. A hemispherical block 15 is fixed on the top surface of the limiting piece 14, and the hemispherical block 15 is embedded in the annular groove 31. When the turntable 3 rotates, the hemispherical block 15 slides relatively in the annular groove 31, and the annular groove 31 prevents the hemispherical block 15 from spontaneously detaching. The limiting piece 14 plays a role in preventing the turntable 3 from detaching from the rotating groove 13, thereby improving the stability of the transfer equipment during operation. The limiting piece 14 made of a metal sheet is elastic, and a person can deform the limiting piece 14 by applying force to the limiting piece 14, so that the hemispherical block 15 detaches from the annular groove 31, and then the limiting piece 14 is rotated outside the turntable 3. At this time, the turntable 3 can be separated from the rotating groove 13, which is convenient for disassembly and assembly.

[0036] The relative position of the support plate 4 and the hinge seat 23 can be fixed, and the fixing structure is as follows: a positioning bolt 41 is threadedly connected to the support plate 4, and the positioning bolt 41 is set through the support plate 4, and a plurality of positioning holes 42 for the positioning bolt 41 to be inserted are opened in the circumferential direction on the hinge seat 23. After the relative position of the support plate 4 and the hinge seat 23 is rotated, the threaded hole on the support plate 4 is aligned with the nearest positioning hole 42, and the personnel screws the positioning bolt 41 into the support plate 4, and inserts the end of the positioning bolt 41 into the aligned positioning hole 42, thereby limiting the relative rotation between the support plate 4 and the hinge seat 23, and improving the stability of the transfer equipment during operation.

[0037] Reference Figure 3 , the screw conveyor 22 is rotatably connected with a support leg 5, the position of the support leg 5 is close to the discharge hopper 22, and the support leg 5 is arranged on both sides of the screw conveyor 22. The relative position of the support leg 5 and the screw conveyor 22 can be fixed, and its fixing structure is as follows: the support leg 5 is threadedly connected with a positioning bolt 251, and the positioning bolt 251 is arranged through the support leg 5. A plurality of positioning holes 24 for the positioning bolt 251 to be inserted are opened along the circumference of the screw conveyor 22. After the relative position of the support leg 5 and the screw conveyor 22 is rotated, the threaded hole on the support leg 5 is aligned with the nearest positioning hole 24. The personnel screws the positioning bolt 251 into the support leg 5, and inserts the end of the positioning bolt 251 into the aligned positioning hole 24, thereby limiting the relative rotation between the support leg 5 and the screw conveyor 22, so that the support leg 5 will not swing at an angle at will, thereby improving stability.

[0038] A support plate 52 is fixed at the lower end of the support leg 5, and a sharp cone 53 is fixed at the bottom end of the support plate 52. The sharp cone 53 is used to be inserted into the ground to prevent the lower end of the support leg 5 from moving, and the support plate 52 is used to contact the ground for support. The combination of the support plate 52 and the sharp cone 53 can significantly improve the stability of the support of the support leg 5.

[0039] The implementation principle of the dredged soil transfer equipment of this embodiment is: the feed end of the screw conveyor 1 is placed on the ship, and the discharge end of the screw conveyor 2 is placed on the shore. The soil entering from the feed hopper 11 is discharged from the discharge hopper 12 through the conveying action of the screw conveyor 1, and then falls into the feed hopper 21, and then the soil is discharged from the discharge hopper 22 through the conveying action of the screw conveyor 2, thereby completing the transfer of the dredged soil from the ship to the shore.

[0040] By setting up two screw conveyors, the screw conveyor 1 connected to the ship can be kept in a flat state as much as possible, which is convenient and safer to install. The screw conveyor 2 can adjust the vertical and horizontal angles, and the output position on the shore can be flexibly adjusted to avoid the position that cannot receive soil, which is easy to use.
