Description

Technical Field

[0001] The present application relates to the field of ship unloader reclaimers, and in particular to a ship unloader with an upper-driven reclaimer. Background Art

[0002] Screw ship unloader is mainly used for picking up and delivering bulk materials at the dock. Its main working units for transporting materials are a horizontally installed screw conveyor and at least one vertically installed screw conveyor and a rotary reclaimer. The horizontally installed screw conveyor is installed on the horizontal support rod of the ship unloader, and the vertically installed screw conveyor is installed on the vertical support arm of the ship unloader. The horizontally installed screw conveyor is installed on the horizontal support arm of the ship unloader, and the reclaimer is installed at the feed port of the vertically installed screw conveyor. The driving motor of the reclaimer will be directly installed on the outer wall of the reclaimer to facilitate power provision.

[0003] The material is fed into the vertically mounted screw conveyor through the material reclaimer, then transported to the horizontally mounted screw conveyor through the vertically mounted screw conveyor, and then transported to the conveyor belt for transportation by the horizontally mounted screw conveyor.

[0004] Small screw ship unloaders are usually designed with two vertically mounted screw conveyors that are rotatably connected to each other to facilitate the more complex space conditions on small bulk carriers and small docks.

[0005] During actual use of the small ship unloader, it was found that the drive motor of the reclaimer would easily collide with the equipment in the cabin. At the same time, since the drive motor of the reclaimer was installed at the feed end of the vertically installed screw conveyor, the end weight of the screw conveyor was increased, and the joint motor that drove the screw conveyor to rotate needed to provide greater torque to drive the rotation of the screw conveyor, resulting in higher energy consumption compared to the designed energy consumption. Utility Model Content

[0009] Through the above technical solution, since the drive motor is located on the end of the No. 2 vertical arm screw conveyor away from the material picker, the collision between the drive motor and the internal equipment of the cabin when the material picker is picking up materials is avoided, so that the drive motor will not be damaged due to collision.

[0010] Optionally, the drive motor is installed away from the rotating connection between the No. 2 vertical arm screw conveyor and the No. 1 vertical arm screw conveyor, and the distance between the drive motor and the material grabber is greater than the distance between the rotating connection between the No. 2 vertical arm screw conveyor and the No. 1 vertical arm screw conveyor and the material grabber.

[0024] The following is combined with Figure 1-3 This application is described in further detail.

[0025] The embodiment of the present application discloses a ship unloader driven by a reclaimer, referring to Figure 1 The ship unloader comprises a ship unloader body 1 and a conveying mechanism 2. The conveying mechanism 2 comprises a horizontal arm screw conveyor 21, a first vertical arm screw conveyor 22, and a second vertical arm screw conveyor 23. One end of the horizontal arm screw conveyor 21 is rotatably mounted on the ship unloader body 1, one end of the first vertical arm screw conveyor 22 is rotatably mounted on the end of the horizontal arm screw conveyor 21 away from the ship unloader body 1, and one end of the second vertical arm screw conveyor 23 is rotatably mounted on the end of the first vertical arm screw conveyor 22 away from the horizontal arm screw conveyor 21. A rotary material reclaimer 3 is also coaxially fixedly mounted on the end of the second vertical arm screw conveyor 23 away from the first vertical arm screw conveyor 22.

[0026] The horizontal arm screw conveyor 21, the No. 1 vertical arm screw conveyor 22 and the No. 2 vertical arm screw conveyor 23 are interconnected. The material picker 3 rotates to take the material out of the cabin and sends it into the No. 2 vertical arm screw conveyor 23, and then it is transported to the conveyor belt along the No. 2 vertical arm screw conveyor 23, the No. 1 vertical arm screw conveyor 22 and the horizontal arm screw conveyor 21 in sequence.

[0027] Reference Figure 1 and Figure 2 The above-mentioned reclaimer 3 needs to be driven by a drive motor 4. The drive motor 4 is located on the second vertical arm screw conveyor 23. The distance between the drive motor 4 and the reclaimer 3 is greater than the distance between the rotation connection axis of the first vertical arm screw conveyor 22 and the second vertical arm screw conveyor 23 and the reclaimer 3. The drive motor 4 is connected to the reclaimer 3 through a transmission shaft 5.

[0028] Reference Figure 2 A mounting plate 6 is welded on the side wall of the No. 2 vertical arm screw conveyor 23. The surface of the mounting plate 6 is perpendicular to the axis of the No. 2 vertical arm screw conveyor 23. The drive motor 4 is detachably mounted on the side of the mounting plate 6 away from the material picker 3 by bolts.

[0029] Reference Figure 2 A reinforcing rib 61 is provided between the side of the mounting plate 6 facing the material picker 3 and the side wall of the second vertical arm screw conveyor 23. The reinforcing rib 61 is in the shape of a right triangle, and the two right-angled sides of the reinforcing rib 61 are respectively welded to the side wall of the second vertical arm screw conveyor 23 and the side of the mounting plate 6 facing the material picker 3.

[0030] Reference Figure 2 and Figure 3 A cylindrical limiting tube 62 is integrally mounted on the side of the mounting plate 6 facing the material reclaimer 3. A mounting tube 7 is coaxially slidably mounted within the limiting tube 62. The mounting tube 7 comprises a transmission tube 71 and two connecting tubes 72. A first retaining ring 711 is coaxially integrally mounted on the inner wall of one end of the transmission tube 71. A first coupling 712 is coaxially slidably mounted within the other end of the transmission tube 71. One end of the first coupling 712 is tightly fitted against one end surface of the first retaining ring 711.

[0031] Reference Figure 2 and Figure 3 The transmission tube 71 is provided with a first retaining ring 711 at one end which is a threaded end. One end of a connecting tube 72 is threadedly installed on the threaded end of the transmission tube 71, and a second retaining ring 721 is coaxially arranged in the connecting tube 72. A bearing 722 is installed between the first retaining ring 711 and the second retaining ring 721. The bearing 722 is coaxial with the transmission tube 71, and the two end faces of the outer ring of the bearing 722 are respectively in contact with one end face of the first retaining ring 711 and one end face of the second retaining ring 721.

[0032] Reference Figure 2 and Figure 3 One end of the second connecting tube 72 is threadedly installed on the end of the first connecting tube 72 away from the transmission tube 71, and a bearing 722 is also provided between the two second retaining rings 721. The two end faces of the outer ring of the bearing 722 are respectively fitted against the opposite end faces of the two second retaining rings 721.

[0033] Reference Figure 2 and Figure 3 Therefore, the number of connecting tubes 72 can be increased or decreased according to the required number of bearings 722, and the port at the free end of the connecting tube 72 farthest from the transmission tube 71 is a normal port rather than a threaded port, so as to facilitate sliding installation in the limiting tube 62. Similarly, if there is only one connecting tube 72, the end of the connecting tube 72 away from the transmission tube 71 is a normal port.

[0034] Reference Figure 2 and Figure 3 A No. 1 key groove 8 is opened on the side wall of the transmission tube 71, and a metal flat key 9 is embedded in the No. 1 key groove 8. At the same time, a No. 2 key groove 621 is opened on the inner wall of the limiting tube 62 to slide with the flat key 9. When the mounting tube 7 is slidably installed in the limiting tube 62, the two sides of the flat key 9 are slidably embedded in the No. 1 key groove 8 and the No. 2 key groove 621 respectively.

[0035] Reference Figure 2 and Figure 3 The outer walls of both the transmission tube 71 and the connecting tube 72 are coated with a rubber layer 73, which covers the first keyway 8. This rubber layer 73 allows the mounting tube 7 to rotate within a relatively small range, facilitating the connection between the transmission shaft 5 and the output shaft of the drive motor 4 and the first coupling 712. This layer also reduces the resonance of the first coupling 712 caused by vibrations generated during operation of the ship unloader, thereby reducing wear on the transmission shaft 5 and the output shaft of the drive motor 4 caused by this resonance.

[0036] Reference Figure 2 and Figure 3 A retaining ring 622 is threadedly mounted on each end of the retaining tube 62. The retaining ring 622 is coaxial with the retaining tube 62, with one end extending out of the tube 62 and having a regular hexagonal cross-section. When the mounting tube 7 is slidably installed in the retaining tube 62, the end surfaces of the mounting tube 7 respectively abut against the opposing surfaces of the two retaining rings 622. To remove the mounting tube 7, simply unscrew either retaining ring 622.

[0037] Reference Figure 2 and Figure 3One end of the transmission shaft 5 is coaxially fixedly connected to the first coupling 712 in the transmission tube 71, and the other end of the transmission shaft 5 extends to the material picker 3. A triangular dustproof cover 10 is fixedly installed on the side wall of the connection end between the material picker 3 and the second vertical arm screw conveyor 23. One side of the driving gear of the material picker 3 is located in the dustproof cover 10. A cylindrical dustproof tube 101 is welded on the dustproof cover 10, and the dustproof tube 101 is coaxial with the material picker 3.

[0038] Reference Figure 2 and Figure 3 A mechanical rotating seal and a second coupling are installed in the dustproof tube 101 in a sliding manner in the direction away from the dustproof shell 10. A connecting shaft is also provided in the dustproof tube 101. One end of the connecting shaft is coaxially connected to the driving gear of the material picker 3, and the other end of the connecting shaft is coaxially connected to the second coupling. The end of the transmission shaft 5 away from the drive motor 4 is coaxially and fixedly connected to the second coupling.

[0039] Reference Figure 2 and Figure 3 A trumpet-shaped dust cover 102 is also welded on the material picker 3. The end of the dust cover 102 with a smaller diameter is fixedly and sealedly connected to the end of the material picker 3 facing the No. 2 vertical arm screw conveyor 23, and the end of the dust cover 102 with a larger diameter extends toward the end of the material picker 3 away from the No. 2 vertical arm screw conveyor 23.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
