Description

Technical Field

[0001] This utility model relates to the field of steel production technology, specifically to a scrap steel hopper that can be vibrated for feeding. Background Technology

[0002] The scrap steel generated during the steel production process is called "returned scrap steel", "self-produced scrap steel" or "recycled scrap steel". It refers to steel scrap that does not become a product (such as trimmed edges, cut ends, etc.). This scrap can be used as raw material for steelmaking. Scrap steel hoppers are containers used to collect scrap steel. When the scrap cut off on the steel production line reaches a certain amount, it needs to be loaded into the scrap steel hopper. The scrap steel in the scrap steel hopper is poured into a dump truck by a crane and transported to the scrap steel site.

[0003] In the current process of rolling bar and wire rod, head and tail sections or scrap materials are generated. Due to the irregular shape of the scrap steel from bars and wire rods, some scrap adheres to the inner wall of the scrap steel hopper when it is dumped, which prevents some scrap from being dumped. This affects the dumping efficiency. Therefore, it is necessary to manually knock the outer wall of the scrap steel hopper to make the scrap adhered to the inner wall fall off. However, the knocking process inevitably involves human-machine contact, increasing the risk of injury. Utility Model Content

[0004] The purpose of this invention is to provide a scrap steel hopper that can be vibrated to discharge scrap steel, so as to solve the problem that some scrap steel is attached to the inner wall of the scrap steel hopper, which requires manual knocking on the outer wall of the scrap steel hopper. However, during the knocking process, human-machine contact is unavoidable, which increases the risk of personnel injury.

[0005] To achieve the above objectives, the basic solution provided by this utility model is as follows: a scrap steel hopper with vibratory feeding, comprising a box body and two booms. The box body is bucket-shaped, with trunnions on both sides of the box body. The two trunnions movably pass through the two booms respectively, and the two booms are rotatably connected to the box body through the trunnions. A crossbeam is provided between the two booms. Several connecting plates are provided on each side of the box body, with each pair of connecting plates forming a group. A rotating shaft is provided between each group of connecting plates, and a rotating plate is provided on each rotating shaft. A torsion spring is provided between each rotating shaft and the rotating plate. Each rotating plate is in a vertical state. A triggering component for triggering the rotation of the rotating plate is provided on the box body. A striking block is provided at the lower end of each rotating plate. A limiting block is provided on the box body. Two fixing plates are provided on one side of the box body, and a lifting rod is provided between the two fixing plates.

[0006] The working principle of this utility model is as follows: when the box is lifted, the lifting rod is used to tilt the box. At this time, the distance between the trigger component and the lifting arm becomes closer until the trigger component touches the lifting arm, triggering the rotating rod to rotate. The torsion spring drives the rotating rod to rotate back. During this process, the striking block repeatedly strikes the box, and the waste residue attached to the inner wall of the box gradually falls off under the action of shaking.

[0007] The beneficial effects of this utility model are as follows: by controlling the rotating plate to rotate back and forth, the striking block strikes the outer surface of the box, and the waste residue slides down along the inclined surface of the box, which improves the dumping efficiency of steel rolling waste. At the same time, it eliminates the need for manual striking of the outer wall of the hopper, reducing human-machine contact and reducing the risk of personnel injury.

[0008] Option 2, a preferred embodiment of the basic design, includes a triggering component comprising a mounting base and support plates. The mounting base is fixedly connected to the housing, and a push rod movably passes through it. The push rod is vertical, with one hemispherical end and a limiting plate at the other. A tension spring is positioned between the limiting plate and the mounting base, movably fitted onto the outside of the push rod. A rack is located on the side of the limiting plate away from the push rod. All support plates are fixedly connected to the housing, and a connecting shaft rotatably connects the support plates. A gear is mounted on the connecting shaft, meshing with the rack. Several protrusions are fixedly passed through the connecting shaft, some flush with the upper end of the rotating plate, and others corresponding to the rotating plate. The housing is struck using the interaction of the boom, push rod, rack, and gear. No additional electric components are required, making the process simple to manufacture and cost-effective.

[0009] Option 3, an optimal choice from the basic option, features two through-holes on both booms, with two trunnions movably connected to the booms through these holes. When the scrap hopper is not needed, the booms are placed vertically. As the booms descend, the trunnions, originally at the bottom of the through-holes, gradually move to the top, facilitating storage and saving space.

[0010] Option 4, a preferred option of the basic design, features several overflow holes on both sides of the container, all located at the bottom of the container. The collected scrap steel, along with its own cooling water, enters the scrap steel hopper, where the overflow holes discharge the accumulated cooling water and other impurities.

[0011] Option 5, an optimal choice from the basic options, features corrugated patterns on both the crossbeam and the lifting rod. These corrugated patterns increase friction during lifting, enhancing the stability of the scrap steel hopper during unloading.

[0012] Option 6, an optimal choice from the basic option, features several casters on the base. These casters facilitate moving the scrap steel hopper to the desired collection area, reducing the workload of workers and accelerating the scrap collection process. Attached Figure Description

The box body 1 is bucket-shaped, and trunnions 3 are provided on both sides of the box body 1. The two trunnions 3 respectively movably pass through the two booms 2, and the two booms 2 are rotatably connected to the box body 1 through the trunnions 3. Each boom 2 is provided with a strip-shaped through hole 14, and the two trunnions 3 are movably connected to the boom 2 through the two strip-shaped through holes 14 respectively. A crossbeam 4 is provided between the two booms 2. Several connecting plates 5 are provided on each side of the box body 1, and every two connecting plates 5 are... Each set consists of a set of connecting plates 5, each with a rotating shaft 6, a rotating plate 7 on each shaft 6, and a torsion spring 8 between each shaft 6 and the rotating plate 7. Each rotating plate 7 is vertical. The housing 1 is equipped with a triggering assembly 9 for triggering the rotation of the rotating plate 7. Each rotating plate 7 has a striking block 10 at its lower end. The triggering assembly 9 includes a mounting base 901 and a support plate 906. The mounting base 901 is fixedly connected to the housing 1, and a push rod 902 movably passes through the mounting base 901. 2. The push rod 902 is in a vertical position. One end of the push rod 902 is hemispherical, and the other end is equipped with a limiting plate 903. A tension spring 904 is provided between the limiting plate 903 and the mounting base 901. The tension spring 904 is movably sleeved on the outside of the push rod 902. A rack 905 is provided on the side of the limiting plate 903 away from the push rod 902. All support plates 906 are fixedly connected to the housing 1. A connecting shaft 907 is rotatably connected between the support plates 906. A gear 908 is provided on the connecting shaft 907. The gear 908 meshes with the rack 905. Several protrusions 909 are fixedly inserted through the shaft 907. The protrusions 909 are flush with the upper end of the rotating plate 7. The protrusions 909 and the rotating plate 7 are respectively provided with limiting blocks 11 on the housing 1. Two fixing plates 12 are provided on one side of the housing 1. A lifting rod 13 is provided between the two fixing plates 12. Several overflow holes 15 are provided on both sides of the housing 1. The overflow holes 15 are all located at the bottom of the housing 1. The crossbeam 4 and the lifting rod 13 are both provided with wavy patterns. Several universal wheels 16 are provided at the bottom of the housing 1.

[0021] The implementation method of this embodiment is as follows:

[0022] During waste disposal, the scrap steel hopper, containing the waste material, is first collected and pushed to the vicinity of the dump truck using the casters 16. Then, the overhead crane lifts the crossbeam 4 and lifting rod 13, tilting the entire container 1. At this point, the push rod 902 tilts along with the container 1, gradually contacting the boom 2. Once the push rod 902 is against the boom 2, as the container 1 continues to tilt, the push rod 902 moves backward, compressing the tension spring 904 until it is tightly pressed against the limiting plate 903. This pushes the limiting plate 903, causing the rack 905 to move backward. The movement of the rack 905 causes the gear 908 to rotate, which in turn drives the connecting shaft 907 to rotate. The connecting shaft 907 then drives several protrusions 909 to rotate together. When the protrusions 909... When the 9th rotating plate is rotated to the opposite side from its stationary position, it will contact the rotating plate 7 and push the rotating plate 7 outward. At this time, the striking block 10 at the lower end of the rotating plate 7 will strike the box 1 once. At this time, the torsion spring 8 will pull the rotating plate 7 back from its outward rotation. After the force of the protrusion 909 and the torsion spring 8, the rotating plate 7 will rotate repeatedly due to inertia, thus achieving multiple strikes to the box 1. After all the collected waste is poured into the tipper truck, first release the lifting rod 13 to restore the box 1 to a vertical state. At this time, the limiting block 11 will abut against the boom 2 to limit the box 1. After the scrap steel hopper is placed on the ground, release the crossbeam 4. Finally, use the caster wheel 16 to move the scrap steel hopper to the next waste collection point.
