Description

Technical Field

[0001] The present invention relates to the field of coal turnover, and in particular to a discharge type turnover box. Background Art

[0002] Existing slag turnover boxes are widely used in the transportation and unloading of slag in industries such as metallurgy and chemical engineering. Their typical structure features a bottom-opening door design secured by latches. During unloading, operators must climb onto the side of the transport vehicle to manually pull out the latches to open the bottom of the box and discharge the material. This traditional method has the following significant drawbacks: Unloading operations are unsafe: The location of the double-door at the bottom requires operators to climb high up on the side of the vehicle to manually operate the machine. This is not only labor-intensive but also carries a high risk of falling or being hit by materials. Furthermore, the open unloading process easily results in the dispersal of large amounts of dust, which seriously pollutes the working environment and poses respiratory hazards, failing to meet modern industrial safety and environmental standards.

[0003] The structural design has inherent limitations: the opening and closing of this type of turnover box relies entirely on manual labor, and cannot be effectively integrated with automated conveying systems or unmanned operation processes, which limits the continuity and efficiency of unloading operations. In the context of the current continuous improvement of industrial automation, this type of design is no longer suitable for the needs of large-scale and continuous production, becoming a bottleneck restricting overall production efficiency.

[0004] Therefore, the existing carbon slag turnover box has obvious deficiencies in safety, environmental protection and automation compatibility. A new structural design is needed to solve the above technical problems and achieve safe and efficient unloading operations. Summary of the Invention

[0005] The present invention aims to provide a discharge type turnover box to achieve safe and efficient discharge operations.

[0006] To achieve the above object, the present invention adopts the following technical solution: a discharge type turnover box, comprising a box body, a self-unloading plate and a connecting unit provided at the bottom of the box body, one side of the self-unloading plate is rotatably connected to the box body, and the other side is detachably connected to the connecting unit; The connecting unit includes a first crossbar, which is rotatably connected to the outside of the box body. A hook is provided on the lower side of the first crossbar. The hook includes a rod body. The side of the rod body extends laterally to form a support portion. The upper surface of the support portion is horizontal. The bottom of the support portion is inclined downward near the side of the rod body. The side of the self-unloading plate away from the rotation center is a free side. The free side of the self-unloading plate is provided with a second crossbar. Before unloading, the second crossbar is supported on the support portion of the hook; When unloading, the lifting equipment lifts the box, the first crossbar drives the hook to rotate, the hook moves away from the second crossbar, the second crossbar loses support, the unloading plate flips downward, thereby opening the bottom of the box, and the material in the box falls out downward; After unloading, the lifting equipment lowers the box, the lower end of the self-unloading plate contacts the ground, the self-unloading plate drives the second cross bar to flip up together, and the second cross bar pushes the bottom of the support part until it returns to the top of the support part, thereby closing the bottom of the box.

[0007] The beneficial effects of this program are: 1. By rotating the first crossbar, the unloading plate flips under the action of gravity, thereby opening the box; the reaction force of the ground on the unloading plate pushes the bottom of the hook, thereby resetting the unloading plate; the operator only needs to trigger the rotation of the first crossbar to achieve semi-automatic, convenient and fast operation, without the need for full worker participation, making the unloading process safe and efficient.

[0008] 2. The first crossbar can be rotated manually or by a driving member. If it is rotated by a driving member, full automation can be achieved.

[0009] 3. After unloading, the lifting equipment will inevitably lower the box. At this time, through the reaction force of the ground and the structure of the connecting unit itself, the bottom of the box will automatically close. No human intervention is required and no drive control is required. It is convenient and fast.

[0010] Furthermore, a rotating wheel is provided on the free side of the self-unloading plate. After unloading, the lifting equipment lowers the box body and the rotating wheel contacts the ground.

[0011] Furthermore, it also includes a tension spring and a first connecting rod unit, the first connecting rod unit is rotatably connected to the box body, the first connecting rod unit includes a vertical rod and a first oblique rod, the vertical rod and the first oblique rod are fixedly connected at the rotation center of the first connecting rod unit, the rotation center of the first connecting rod unit is higher than the rotation center of the first cross rod, the lower end of the first oblique rod is provided with a strip hole along the length direction, the first cross rod is provided with a protrusion, and the protrusion is slidably arranged in the strip hole; the two ends of the tension spring are respectively connected to the box body and the vertical rod; Before unloading, the tension spring is set horizontally and the vertical rod is set vertically; When unloading, the upper part of the vertical rod is pulled away from the box body, driving the strip hole of the first oblique rod to rotate upward, and the protrusion slides in the strip hole, driving the first cross bar and the hook to rotate, thereby opening the bottom of the box body.

[0012] Furthermore, it also includes a pull rod, which includes a slide tube and a sliding rod. One end of the slide tube is connected to the box body, and a strip-shaped notch is provided at one end of the slide tube close to the box body. One end of the sliding rod passes through the slide tube and is rotatably connected to the slide tube. A short cross bar is provided at the end of the slide rod, and the short cross bar is slidably set in the strip-shaped notch. After the short cross bar passes through the strip-shaped notch, it is used to pull the upper part of the vertical rod away from the box body.

[0013] Furthermore, an L-shaped pulling portion is provided on the side of the vertical rod away from the box body. When unloading, the short cross bar is inserted between the pulling portion and the vertical rod, and the short cross bar of the sliding rod pulls the pulling portion and the upper part of the vertical rod away from the box body.

[0014] Furthermore, a support member for supporting the slide and the slide rod is provided on the side of the box body. A first rotating shaft is horizontally connected to the box body, a second rotating shaft is vertically connected to the first rotating shaft, and the second rotating shaft is connected to the end of the slide.

[0015] Furthermore, the end position of the strip notch needs to meet the following requirements: when unloading, the short cross bar pulling part and the upper part of the vertical bar are away from the box body until the pulling part rotates too much with the vertical bar, and the short cross bar can pass over the upper end of the pulling part.

[0016] Furthermore, two self-unloading plates are symmetrically provided on the box body, and a plurality of strip-shaped connecting pieces are vertically provided on the side of the self-unloading plates away from the central axis of the box body. The upper end of the connecting piece is hinged to the side of the box body, and the lower end of the connecting piece is fixedly connected to the self-unloading plate.

[0017] Furthermore, the outer sleeve of the tension spring is provided with a horizontal sleeve, which is fixed on the box body. When unloading, the short cross bar can pass over the upper end of the pulling part, and the vertical bar collides with the horizontal sleeve under the tension of the tension spring.

[0018] This solution also has the following effects: 1. The free side of the dump deck is equipped with a running wheel so that after unloading, when the ground supports the dump deck, the free side can move smoothly horizontally relative to the ground and return to its original position.

[0019] 2. The first cross bar at the bottom of the box is connected through the first connecting rod unit to facilitate manual operation while standing on the side of the box.

[0020] 3. Pull the vertical rod horizontally through the tension spring so that it can automatically reset after pulling the vertical rod.

[0021] 4. To further ensure the safety of operators, operators should keep a certain distance from the box when unloading. Therefore, this solution adds a pull rod, which pushes the first connecting rod unit to rotate through the cooperation of the slide cylinder and the slide rod, thereby opening the bottom of the box. To facilitate the removal and use of the pull rod, the pull rod is connected to the box body so that it can be rotated horizontally to be flush with the side of the box and placed on the support for daily storage. It is also convenient to adjust the pull rod angle vertically to adapt to the operator's position in different scenarios.

[0022] 5. Since the operator is at a certain distance from the box, and the material may not be poured out cleanly if the bottom of the box is opened directly, this solution adds the following technical features to make the material in the box pouring out more cleanly: 1) connecting piece and self-unloading plate are fixedly connected, and the connecting piece and the side of the box are hingedly connected, so that when the bottom of the box is opened, the self-unloading plate is in an inclined state, and when the material falls, it continuously hits the self-unloading plate, thereby increasing the shaking of the self-unloading plate, and further causing the box to vibrate up and down, thereby causing the material on the inner wall of the box to fall; if the side of the self-unloading plate is directly hingedly connected with the bottom of the box, when the bottom of the box is opened, the self-unloading plate is close to a vertical state, and the material basically does not hit the self-unloading plate, and does not produce a large shaking.

[0023] 2) In order to quickly unload, ensure that the material falls directly below the box, the two self-unloading plates are symmetrically arranged, when the bottom of the box is opened, the horizontal shaking of the two self-unloading plates cancels each other out, only leaving vertical vibration, reducing the vibration effect; in this scheme, when unloading, the short horizontal rod can pass over the upper end of the pulling part after the pulling part rotates with the vertical rod at too large an angle, after the pulling part loses support, the vertical rod is quickly pulled back to the original position by the tension spring, the vertical rod hits the horizontal sleeve, causing the box to rotate horizontally, thereby destroying the symmetry of the two self-unloading plates, making the vibration frequency of the two self-unloading plates inconsistent, and the horizontal force cannot be completely canceled out, thereby increasing the vibration amplitude, and causing the material on the inner wall of the box to fall.
