Description

Technical Field

[0001] This utility model relates to the field of waste hopper technology, and in particular to a scrap shear waste hopper for a steel production line. Background Technology

[0002] The scrap hopper of a scrap shear is a container installed below the scrap shear equipment to receive and store the scrap materials cut by the scrap shear, such as scrap steel bars and offcuts. It effectively prevents scrap from scattering and accumulating on the production line, maintaining a clean production environment, and also facilitates subsequent processing and recycling of the scrap. The scrap hopper typically works closely with the scrap shear equipment. When the scrap shear cuts strips or plates, the generated scrap is directly conveyed into the scrap hopper. The scrap hopper is designed with a reasonable capacity and structure to ensure stable reception and storage of scrap, while also facilitating subsequent unloading operations.

[0003] In practical use, when a certain amount of waste material is collected inside the waste hopper, operators need to remove the collected debris to facilitate subsequent use. However, if the waste hopper lacks an effective rate control mechanism during unloading, it can lead to significant dust generation during unloading when there is a large amount of waste inside, severely polluting the environment and affecting the health of workers. These problems directly result in reduced production efficiency, a deteriorated operating environment, and failure to meet the stringent environmental and health requirements of modern steel production lines.

[0004] To address the shortcomings of existing technologies, a scrap shear hopper for steel production lines is proposed, which can improve the rate control capability of the unloading process, effectively reduce the generation of smoke and dust, thereby improving the working environment, protecting the health of employees, and better meeting the environmental protection and health requirements of modern steel production lines.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Reference Figure 1 -7. A scrap hopper for edge trimming in a steel production line, comprising a holding hopper 1, a base frame 2 fixedly connected to both sides of the bottom of the holding hopper 1, a closing plate 5 provided on both sides of the bottom of the holding hopper 1, a discharge chute adapted to the closing plate 5 being provided at the center of the bottom of the holding hopper 1, a sliding groove 11 being provided on one side of the base frame 2, and sliding rods 6 adapted to the sliding groove 11 being fixedly connected to both sides of the closing plate 5.

[0027] A limiting block 8 is fixedly connected at the center of the inner cavity of the slide 11. Telescopic rods 9 are fixedly connected to both sides of the limiting block 8, and one end of the telescopic rod 9 is fixedly connected to one side of the adjacent slide rod 6. A mounting box 4 is horizontally arranged on one side of one of the base frames 2, and a bidirectional screw 12 is horizontally arranged in the inner cavity of the mounting box 4. Threaded sleeves 13 are sleeved on both sides of the outer ring of the bidirectional screw 12. An extension block 7 is fixedly connected to the top of the outer ring of the threaded sleeve 13. A through groove 15 is opened on the top of the mounting box 4. The top of the extension block 7 passes through the through groove 15, and one side of the extension block 7 abuts against one side of the corresponding slide rod 6.

[0028] Furthermore, side plates 3 are provided on both sides of the mounting box 4, and one side of the side plate 3 is fixedly connected to one side of the corresponding base frame 2. Through the cooperation between the side plate 3 and the base frame 2, the side plate 3 provides stable support for the mounting box 4 during the working process, ensuring the stability of the mounting box 4 and its internal components during rotation and unloading. This achieves the effect of enhancing the overall structural stability of the waste hopper, ensuring safety and reliability during the production process.

[0029] Furthermore, a rotary motor 16 is installed on one side of one of the side plates 3. The output shaft of the rotary motor 16 passes through a bushing and is connected to one side of the mounting box 4 via a drive shaft. The other side of the mounting box 4 is rotatably connected to the corresponding side plate 3 via a rotating shaft. Through the coordinated arrangement of the rotary motor 16, bushing, side plate 3, and mounting box 4, the rotary motor 16 can drive the mounting box 4 to rotate during the working process, thereby controlling the opening and closing state of the closing plate 5 and realizing the opening and closing of the unloading channel. This achieves the effect of flexibly controlling the opening and closing of the unloading channel, improving the sealing performance of the waste hopper and the flexibility of unloading control.

[0030] Furthermore, a drive motor 14 is installed on one inner wall of the mounting box 4. The output shaft of the drive motor 14 is connected to one end of the bidirectional lead screw 12, and the other end of the bidirectional lead screw 12 is rotatably connected to one inner wall of the mounting box 4 via a rotating shaft. Through the cooperation of the drive motor 14, the bidirectional lead screw 12 and the mounting box 4, in the working process, the drive motor 14 can drive the bidirectional lead screw 12 to rotate, thereby driving the extension block 7 and the slide bar 6 to move, controlling the opening degree of the closing plate 5, achieving the effect of precisely controlling the unloading rate, and avoiding the dust problem caused by excessive speed.

[0031] Furthermore, a spring 10 is installed on the outer ring of the telescopic rod 9. One end of the spring 10 is fixedly connected to one side of the corresponding limiting block 8, and the other end of the spring 10 is fixedly connected to one side of the corresponding sliding rod 6. Through the coordinated arrangement of the spring 10, the telescopic rod 9, the limiting block 8, and the sliding rod 6, the spring 10 and the telescopic rod 9 provide buffering and shock absorption for the movement of the closing plate 5 during the working process, reducing the impact force during unloading. This achieves the effect of protecting the waste hopper structure and reducing noise and dust emissions, thus improving the working environment for operators.

[0032] Furthermore, the top of the closing plate 5 is in contact with the lower surface of the holding hopper 1. Through the cooperation between the closing plate 5 and the holding hopper 1, the top of the closing plate 5 is in contact with the lower surface of the holding hopper 1 during the working process, ensuring the sealing of the waste hopper in the closed state. This achieves the effect of improving the sealing performance of the waste hopper, preventing the leakage and scattering of waste, and maintaining the cleanliness of the production environment.

[0033] In summary: When the scrap shear cuts strip or steel plate, the resulting waste is directly guided into the holding hopper 1. As the waste accumulates, when it reaches a point where it needs to be cleaned, the operator needs to perform an unloading operation. First, the operator controls the drive motor 14 to run, and its output shaft begins to rotate, driving the bidirectional lead screw 12 to rotate through the transmission connection. The rotational motion of the bidirectional lead screw 12 is converted into the linear movement of the extension blocks 7 through the screw sleeve 13. Due to the design of the bidirectional lead screw 12, the two extension blocks 7 move simultaneously and in opposite directions. Guided by the through groove 15, the extension blocks 7 contact the corresponding slide rods 6 and push them to move. Since the slide rods 6 are fixedly connected to the closing plate 5 and slide within the sliding groove 11, the closing plate 5 is smoothly pushed open, thereby opening the discharge chute and allowing the waste to be discharged from the holding hopper 1. During the unloading process, if the operator needs to reduce the unloading rate, the operator can control the drive motor 14 to rotate in the opposite direction, causing the two extension blocks 7 to move closer to each other. At this point, under the force of spring 10 and telescopic rod 9, the two closing plates 5 will move closer to each other, thereby reducing the opening size of the discharge chute and achieving the effect of reducing the unloading rate. One end of the telescopic rod 9 is fixed to the limiting block 8, and the other end is connected to the sliding rod 6, which not only limits the movement range of the closing plate 5, but also ensures the smoothness of the movement of the closing plate 5. Spring 10 absorbs part of the impact force and slows down the movement speed of the closing plate 5. Especially when reducing the unloading rate, the buffering effect of spring 10 is more obvious, effectively reducing the dust generated by rapid unloading. This allows operators to flexibly adjust the unloading rate according to actual needs, avoiding dust problems caused by excessive speed. When reducing the unloading rate, the buffering effect of spring 10 is more obvious, effectively reducing the impact force generated by rapid movement, protecting the structure of the waste hopper from damage, and reducing noise and dust emissions during the unloading process. By precisely controlling the unloading rate and effectively reducing dust generation, this waste hopper significantly improves the working environment of operators. This not only helps protect the health of employees, but also improves their work efficiency and satisfaction. At the same time, it reduces equipment maintenance costs and the risk of production interruption caused by smoke and dust pollution.

[0034] In the scrap shearing operation of a steel production line, after the scrap shear cuts the strip or steel plate, the waste is guided into the holding hopper 1. After unloading, the operator starts the rotary motor 16, whose output shaft drives the mounting box 4 to rotate. This rotation causes the extension block 7 to lose contact with the corresponding slide rod 6. At this time, under the force of the spring 10, the two closing plates 5 move closer to each other, thus sealing the bottom of the holding hopper 1 and closing the unloading channel. When it is necessary to open the unloading channel, the operator simply reverses the rotary motor 16, causing the mounting box 4 to rotate back to its original position. At this time, the extension block 7 contacts the slide rod 6 again, and under the action of the drive motor 14, pushes the closing plate 5 to move, opening the discharge chute for unloading, thereby improving the control method for rapid cutting and unloading at the bottom of the scrap hopper.
