Description

Technical Field

[0001] This utility model relates to the field of port machinery technology, specifically to a scraper arch-breaking device for a ship unloader. Background Technology

[0002] Currently, the ship unloading equipment commonly used in ports can be divided into intermittent and continuous types. Intermittent types are mainly bridge-type grab unloaders, which are characterized by their wide applicability and simple maintenance, but are not environmentally friendly, have high costs, high energy consumption, and low efficiency, and have been gradually phased out by the market. Continuous ship unloaders are mainly divided into chain bucket unloaders and buried scraper unloaders. This application mainly discusses a technology applied to buried scraper unloaders.

[0003] Scraper unloaders are widely used in grain terminals. They are characterized by high loading and unloading efficiency for materials with good flowability (such as corn and soybeans), but there is no good solution for materials that are prone to caking (such as fertilizers and cement), especially for materials that have already caking. Summary of the Invention

[0004] In order to solve the technical problem that the existing scraper unloaders are not good at handling materials that are prone to caking, this application proposes a scraper arch breaking device for the unloader, which solves the above two technical problems.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] This utility model provides a device for breaking arches on a scraper plate of a ship unloader, comprising: a fixed plate, which is sleeved on the support of the scraper plate of the ship unloader and is movably disposed at the feed inlet at the bottom of the scraper plate to push out or retract the support of the scraper plate from the feed inlet; and a rotating plate, which is rotatably disposed on the fixed plate and located on the side of the fixed plate facing the material, wherein an arch-breaking component is disposed on the side of the rotating plate facing the material.

[0007] Furthermore, the fixed plate is vertically and flexibly mounted on the scraper of the ship unloader via multiple sets of hydraulic cylinders. The cylinder body of the hydraulic cylinder is connected to the outer wall of the support of the scraper of the ship unloader near the feed inlet, and the piston rod of the hydraulic cylinder is connected to the fixed plate.

[0008] Furthermore, the tail end of the cylinder body of the hydraulic cylinder is hinged to the outer wall of the support of the scraper of the unloader, and the piston rod of the hydraulic cylinder is hinged to the side of the fixed plate away from the material. When the piston rod of the hydraulic cylinder retracts into the cylinder body, the fixed plate is sleeved on the support of the scraper of the unloader. When the piston rod of the hydraulic cylinder extends out of the cylinder body, the fixed plate extends out of the support of the scraper of the unloader from the feed port.

[0009] Furthermore, the rotating disk is mounted on the fixed disk via a gear bearing. The gear bearing includes an inner ring fixedly connected to the fixed disk and an outer ring rotatably mounted on the inner ring. Meanwhile, a hydraulic motor for driving the rotating disk is mounted on the fixed disk. A drive pinion is mounted on the shaft of the hydraulic motor, and the drive pinion meshes with the outer teeth of the outer ring of the gear bearing.

[0010] Furthermore, the arch-breaking assembly includes multiple arch-breaking blades evenly distributed on the rotating disk.

[0011] Furthermore, the arch-breaking blade is also equipped with multiple arch-breaking rakes.

[0012] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:

[0013] This utility model relates to a scraper-mounted arch-breaking device for ship unloaders. Targeting materials prone to caking in ships, it features a liftable fixed plate at the feed inlet at the bottom of the scraper. A rotating disc is mounted on the fixed plate, and an arch-breaking component is installed on the rotating disc to actively break up the arch as it rotates. When arch breaking is needed, the fixed plate can be pushed down to extend the scraper's support, effectively solving the arching problem. When the arch-breaking function is not needed, the fixed plate retracts upwards to extend the scraper's support, effectively improving efficiency and broadening its applicability.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] like Figure 1-3 As shown, this utility model provides a device for breaking arches of a scraper plate of a ship unloader, including a fixed disk 1 and a rotating disk 2. The fixed disk 1 is sleeved on the support a of the scraper plate of the ship unloader and is movably configured at the feed inlet at the bottom of the scraper plate of the ship unloader so as to push out or retract the support a of the scraper plate of the ship unloader from the feed inlet. The rotating disk 2 is rotatably configured on the fixed disk 1 and is located on the side of the fixed disk 1 facing the material. An arch-breaking component 21 is configured on the side of the rotating disk 2 facing the material.

[0020] The arch-breaking device of the ship unloader buried scraper of this utility model can be modified and added to the existing ship unloader buried scraper, which is low in cost; the modified ship unloader buried scraper has both an arch-breaking mode that can realize the arch-breaking function and an efficient mode without the arch-breaking function, which greatly expands its applicability.

[0021] In one specific embodiment of this utility model, the fixed plate 1 is vertically and flexibly mounted on the scraper plate of the ship unloader by multiple sets of hydraulic cylinders 3. In this embodiment, there are four sets of hydraulic cylinders 3. The cylinder body of the hydraulic cylinder 3 is connected to the outer wall of the bracket a of the scraper plate of the ship unloader near the feed inlet, and the piston rod of the hydraulic cylinder 3 is connected to the fixed plate 1.

[0022] Furthermore, the rear end of the cylinder body of hydraulic cylinder 3 is hinged to the outer wall of the bracket a of the scraper of the unloader, and the piston rod of hydraulic cylinder 3 is hinged to the side of fixed plate 1 away from the material. When the piston rod of hydraulic cylinder 3 retracts into the cylinder body, fixed plate 1 is fitted onto the bracket a of the scraper of the unloader. When the piston rod of hydraulic cylinder 3 extends out of the cylinder body, fixed plate 1 extends out of the bracket a of the scraper of the unloader from the feed inlet. The hinged connection of hydraulic cylinder 3 makes the installation of fixed plate 1 more versatile and easier to adjust.

[0023] In one specific embodiment of this utility model, the rotating disk 2 is assembled on the fixed disk 1 by a gear bearing 4. The gear bearing 4 includes an inner ring 41 fixedly connected to the fixed disk 1 and an outer ring 42 rotatably assembled on the inner ring 41. Meanwhile, a hydraulic motor 5 for driving the rotating disk 2 is installed on the fixed disk 1. A driving pinion 51 is installed on the shaft of the hydraulic motor 5, and the driving pinion 51 meshes with the outer teeth on the outer periphery of the outer ring 42 of the gear bearing 4.

[0024] In one specific embodiment of the present invention, the arch-breaking component 21 includes a plurality of arch-breaking blades 22 evenly distributed on the rotating disk 2, and the arch-breaking blades 22 are vertical on the rotating disk 2.

[0025] Furthermore, the arch-breaking blade 22 is also equipped with multiple arch-breaking rakes 23, which are vertically mounted on the arch-breaking blade 22.

[0026] It should be understood that the specific embodiments described above are only for explaining the present invention and are not intended to limit the present invention.
