[0002] Shipbuilding, also known as ship construction, is a specialized manufacturing industry dedicated to building or manufacturing various types of vessels. It encompasses multiple areas, including ship design, materials, equipment, construction, and repair. During the shipbuilding process, surface polishing machines are used to remove rust from steel plates.

[0003] When existing flat polishing machines remove rust from steel plates, debris and impurities adhere to the conveyor belt. If these impurities are not removed in time, they will form a material drop zone in the entire working channel, causing environmental pollution. Therefore, a rust removal device for shipbuilding has been proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rust removal device for shipbuilding, which has advantages such as automatic conveyor belt cleaning. It solves the problem that when existing flat polishing machines remove rust from steel plates, the conveyor belt will be covered with debris and impurities. If these impurities are not removed in time, they will form a material drop zone in the entire working channel, causing environmental pollution.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rust removal device for shipbuilding, comprising a body and a cleaning chamber.

[0007] Furthermore, a door is movably installed on the left side of the cleaning chamber.

[0008] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0009] 1. This rust removal device for shipbuilding uses a cleaning mechanism to remove accumulated impurities from the conveyor belt as it moves, causing them to fall into the cleaning port. Starting the drive motor rotates the brush on the rotating shaft, sweeping away the debris and impurities attached to the conveyor belt. Starting the negative pressure fan creates negative pressure in the cleaning chamber, allowing dust and impurities to enter through the discharge port and accumulate on the filter screen. This achieves the purpose of automatically cleaning the conveyor belt.

[0010] 2. This rust removal device for shipbuilding, through its scraping mechanism, allows the rust-removed steel plate to enter the U-shaped chamber. Simultaneously, the dual-shaft cylinders on both sides move the cleaning brush downwards to the surface of the steel plate. At the same time, the feed hopper moves between two adjacent rollers. As the steel plate travels on the rollers, the cleaning brush removes debris from the surface of the steel plate. The removed debris falls from the feed hopper into the cleaning chamber, thus achieving automatic cleaning of the workpiece and improving the practicality of the device. Attached Figure Description

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] Please see Figure 1-3 A rust removal device for shipbuilding in this embodiment includes a body 1 and a cleaning chamber 3. A conveyor belt 2 is provided on the body 1. A roller conveyor mechanism 4 is provided above the cleaning chamber 3. A U-shaped chamber 5 is provided above the roller conveyor mechanism 4. A cleaning mechanism 7 is provided on the right side of the cleaning chamber 3 and below the conveyor belt 2. A filter screen 8 is fixedly installed at the bottom of the interior of the cleaning chamber 3. A negative pressure fan 9 is fixedly installed inside the cleaning chamber 3 and below the filter screen 8. A scraping mechanism 6 is provided on the cleaning chamber 3.

[0017] In this embodiment, the roller conveying mechanism 4 includes multiple round rollers and mounting frames. Mounting frames are fixedly installed at both the front and rear ends of the top of the cleaning chamber 3. Multiple round rollers are rotatably installed between two mounting frames. A pulley with one end penetrating through and extending to the front of the front mounting frame is fixedly installed on the front of the round roller. The pulley is movably connected by a belt. A drive motor is fixedly installed on the left end of the front of the front mounting frame. The output end of the drive motor is fixedly connected to the left pulley. Tensioning pulleys are provided on the front of the front mounting frame, both above and below the belt.

[0018] Specifically, starting the drive motor can rotate the left-side pulley, which transmits power to other pulleys via belts. In this way, multiple rollers can rotate simultaneously to transport workpieces. The tension wheel can adjust the belt tension between two adjacent pulleys.

[0019] In this embodiment, the scraping mechanism 6 includes a cleaning brush 61, a feeding hopper 62, a dual-axis cylinder 63, and a connecting rod 64. The cleaning brush 61 is movably installed inside the U-shaped chamber 5, and the feeding hopper 62 is movably installed inside the cleaning chamber 3. Connecting rod holes are provided on both the front and back sides of the U-shaped chamber 5 and the cleaning chamber 3.

[0020] It should be noted that the dual-shaft cylinder 63 is located on one side of the two mounting brackets facing away from each other.

[0021] Specifically, after the rust-removed steel plate enters the U-shaped chamber 5, the dual-axis cylinders 63 on both sides of the operation bring the cleaning brush 61 downwards to the surface of the steel plate. At the same time, the feed hopper 62 moves between two adjacent rollers. As the steel plate moves on the rollers, the cleaning brush 61 can brush away the debris on the surface of the steel plate. The brushed debris can fall from the feed hopper 62 into the cleaning chamber 3. In this way, the automatic cleaning of the workpiece is achieved.

[0022] In this embodiment, the cleaning mechanism 7 includes a cleaning chamber 71, a cleaning port 72, a drive motor 73, a rotating shaft 74, a brush 75, and a discharge port 76.

[0023] Specifically, as the conveyor belt 2 moves, the impurities accumulated on it can fall into the cleaning port 72. The drive motor 73 is started, which rotates the brush 75 on the rotating shaft 74 to sweep off the debris and impurities attached to the conveyor belt 2. The negative pressure fan 9 is started, and negative pressure is generated in the cleaning chamber 3. The dust and impurities in the cleaning chamber 71 can enter the cleaning chamber 3 through the discharge port 76 and accumulate on the filter screen 8.

[0024] In this embodiment, a door is movably installed on the left side of the cleaning chamber 3.

[0025] Specifically, opening the compartment door allows for the cleaning of debris and impurities.
