Description

Technical Field

[0001] This utility model relates to the field of coal turnover, specifically to a discharge-type turnover box. Background Technology

[0002] Existing slag transfer boxes are widely used in the transfer and unloading of slag in industries such as metallurgy and chemicals. Their typical structure features a bottom-opening double-door design, secured with latches. During unloading, workers must climb onto the side of the transport vehicle to manually pull the latches to open the bottom of the box and discharge the material. This traditional method has the following significant drawbacks: The unloading operation is unsafe: the location of the bottom double doors means that operators must climb to a high point on the side of the vehicle to manually operate the equipment, which is not only physically demanding but also carries a high risk of falling and being injured by falling materials. Furthermore, the open-top unloading process easily leads to the dispersion of large amounts of dust, severely polluting the working environment and posing a hazard to personnel's respiratory system, failing to meet modern industrial safety and environmental protection standards.

[0003] The structural design has inherent limitations: the opening and closing of this type of turnover box relies entirely on manual operation, making it impossible to effectively integrate with automated conveying systems or unmanned processes, thus limiting the continuity and efficiency of unloading operations. Given the continuous improvement of industrial automation, this design is no longer suitable for the needs of large-scale, continuous production, becoming a bottleneck restricting the improvement of overall production efficiency.

[0004] Therefore, existing carbon slag turnover boxes have significant shortcomings in terms of 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. Utility Model Content

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

[0006] To achieve the above objectives, 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 at the bottom of the box body, one side of the self-unloading plate being rotatably connected to the box body, and the other side being detachably connected to the connecting unit; The connecting unit includes a first crossbar, which is rotatably connected to the outside of the box. A hook is provided on the lower side of the first crossbar. The hook includes a rod body, which extends laterally to form a support part. The upper surface of the support part is horizontal, and the bottom of the support part is inclined downward on the side near the rod body. The side of the self-unloading plate away from the rotation center is the free side, and a second crossbar is provided on the free side of the self-unloading plate. Before unloading, the second crossbar is supported on the hook's support. During 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 self-unloading plate flips downward, thereby opening the bottom of the box, and the material inside the box falls downward; After unloading, the lifting equipment lowers the box body, and the lower end of the self-unloading plate contacts the ground. The self-unloading plate drives the second crossbar to flip up together. The second crossbar pushes open the bottom of the support part until it returns to the top of the support part, thereby closing the bottom of the box body.

[0007] The beneficial effects of this plan are: 1. By rotating the first crossbar, the unloading plate flips under gravity, thereby opening the box; the reaction force of the ground on the unloading plate pushes open 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-automation, which is convenient and quick, without the need for full-time worker participation, making the unloading process safe and efficient.

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

[0009] 3. After unloading, the lifting equipment will lower the box. At this time, the bottom of the box will automatically close by using the ground reaction force and the structure of the connecting unit itself. No personnel intervention or drive control is required, which is convenient and quick.

[0010] Furthermore, the free side of the self-unloading plate is equipped with a roller. After unloading, the lifting equipment lowers the box, and the roller contacts the ground.

[0011] Furthermore, it also includes a tension spring and a first linkage unit. The first linkage unit is rotatably connected to the housing. The first linkage unit includes a vertical rod and a first diagonal rod, which are fixedly connected at the rotation center of the first linkage unit. The rotation center of the first linkage unit is higher than the rotation center of the first horizontal rod. The lower end of the first diagonal rod has a strip-shaped hole along its length, and the first horizontal rod has a protrusion that is slidably disposed in the strip-shaped hole. The two ends of the tension spring are respectively connected to the housing and the vertical rod. Before unloading, the tension spring is set horizontally and the vertical rod is set vertically; During unloading, the upper part of the vertical rod is pulled away from the box body, which causes the strip hole of the first diagonal rod to rotate upward. The protrusion slides in the strip hole, causing the first horizontal rod and hook to rotate, thereby opening the bottom of the box body.

[0012] Furthermore, it also includes a pull rod, which consists of a slide cylinder and a slide bar. One end of the slide cylinder is connected to the box body, and the end of the slide cylinder near the box body has a strip-shaped notch. One end of the slide bar passes through the slide cylinder and is rotatably connected to the slide cylinder. The end of the slide bar has a short crossbar, which is slidably set in the strip-shaped notch. After the short crossbar passes through the strip-shaped notch, it is used to pull the upper part of the vertical bar away from the box body.

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

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

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

[0016] Furthermore, two self-unloading plates are symmetrically arranged on the box body. Several strip-shaped connectors are vertically arranged on the side of the self-unloading plate away from the central axis of the box body. The upper end of the connector is hinged to the side of the box body, and the lower end of the connector is fixedly connected to the self-unloading plate.

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

[0018] This solution also has the following effects: 1. The free side of the self-unloading plate is equipped with a roller so that after unloading, when the ground supports the self-unloading plate, the free side can move smoothly horizontally relative to the ground and return to the initial position.

[0019] 2. The first crossbar at the bottom of the box is connected through the first linkage unit so that it is easy for a person to operate from the side of the box.

[0020] 3. Use a tension spring to hold the vertical rod horizontally so that it can automatically return to its original position after being pulled.

[0021] 4. To further ensure operator safety, operators should maintain a certain distance from the box during unloading. Therefore, this solution adds a pull rod. Through the cooperation of the slide cylinder and the slide rod, the first linkage unit is rotated to open the bottom of the box. To facilitate the retrieval and use of the pull rod, the pull rod is rotatably connected to the box so that it can be rotated horizontally to be flush with the side of the box and placed on the support for easy storage. It also facilitates vertical rotation to adjust the angle of the pull rod to adapt to the operator's position in different scenarios.

[0022] 5. Since the operator is a certain distance from the container, and directly opening the bottom of the container may result in incomplete emptying of materials, this solution incorporates the following technical features to ensure more complete emptying of materials from the container: 1) The connector and the self-unloading plate are fixedly connected, and the connector and the side of the box are hinged, so that when the bottom of the box is opened, the self-unloading plate is in an inclined state. At this time, when the material falls, it will continuously hit the self-unloading plate, thereby increasing the shaking of the self-unloading plate, which in turn causes the box to vibrate up and down, shaking the material off the inner wall of the box. If the side of the self-unloading plate is directly hinged to 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 will not hit the self-unloading plate, and there will be no large shaking.

[0023] 2) To ensure rapid unloading and that the material falls directly below the container, this design uses two symmetrically arranged self-unloading plates. When the bottom of the container is opened, the horizontal swaying of the two self-unloading plates cancels each other out, leaving only vertical vibration and reducing the vibration effect. However, in this design, during unloading, if the pulling part rotates too much with the vertical rod, the short horizontal bar can pass over the upper end of the pulling part. After the pulling part loses support, the vertical rod is quickly pulled back to its original position by the tension spring. The vertical rod hits the horizontal sleeve, causing the container to rotate horizontally. This disrupts the symmetry of the two self-unloading plates, causing their vibration frequencies to be inconsistent. The horizontal forces cannot be completely canceled out, thus increasing the vibration amplitude and shaking the material off the inner wall of the container. Attached Figure Description

The right side of the rod body 33 extends laterally to form a support part 34. The upper surface of the support part 34 is horizontal, and the bottom of the support part 34 is inclined downward on the side near the rod body 33. The second crossbar 25 is supported on the support part 34 of the hook 32. The rectangular portion 12 is also provided with a connecting rod unit, a horizontal sleeve 42, and a tension spring 41. The connecting rod units are all rotatably connected to the rectangular portion 12.

The first connecting rod unit is as follows: Figure 4 As shown, the first linkage unit includes a vertical rod 53 and a first diagonal rod 55. A connecting protrusion 54 is integrally formed on the upper side of the vertical rod 53. The vertical rod 53 and the first diagonal rod 55 are integrally connected at the rotation center of the first linkage unit. The rotation center of the first linkage unit is higher than the rotation center of the first horizontal rod 3. A strip-shaped hole 56 is provided at the lower end of the first diagonal rod 55 along the length direction. A protrusion 35 is provided on the first horizontal rod 3. The protrusion 35 is slidably disposed in the strip-shaped hole 56. A horizontal sleeve 42 is welded to the front side of the rectangular part 12 of the housing 1. The right end of the tension spring 41 is welded to the inner side of the horizontal sleeve or passes through the horizontal sleeve and is welded to the housing 1. The left end of the tension spring 41 passes through the horizontal sleeve and is welded to the connecting protrusion 54 of the vertical rod 53. An L-shaped pulling part 58 is provided on the side of the vertical rod 53 away from the central axis 16. The second linkage unit includes a second diagonal rod 57, which is symmetrically arranged with the first diagonal rod 55. Furthermore, it is connected in the same way as the first horizontal bar 3, with the upper end of the second diagonal bar 57 and the end of the fifth rotating shaft 51 being integrally formed.

[0031] The rectangular part 12 is also provided with a pull rod, a first rotating shaft 61 and a second rotating shaft 62, such as Figure 5 As shown, the pull rod includes a slide cylinder 63 and a slide rod 65. The first rotating shaft 61 is vertically arranged and horizontally rotatably connected to the rectangular part 12. The second rotating shaft 62 is integrally formed with the upper end of the first rotating shaft 61. The second rotating shaft 62 is horizontally arranged and vertically rotatably connected to the right end of the slide cylinder 63. A strip-shaped notch 64 is opened along the length direction on the right side of the slide cylinder 63. The right end of the slide rod 65 passes into the slide cylinder 63 and is rotatably connected to the slide cylinder 63. A short horizontal bar 66 is integrally formed at the right end of the slide rod 65. The short horizontal bar 66 is slidably arranged in the strip-shaped notch 64. After the short horizontal bar 66 passes through the strip-shaped notch 64, it is used to pull the upper part of the vertical rod 53 away from the box body 1. A handle 67 is provided at the left end of the slide rod 65. A limiting section 68 is provided on the slide rod 65. The outer diameter of the limiting section 68 is larger than the inner diameter of the slide cylinder 63. The limiting section 68 is arranged between the slide cylinder 63 and the handle 67. A return spring can be installed between the slide cylinder 63 and the slide rod 65 as needed, so that the short crossbar 66 can automatically return to the fixed position.

[0032] The following is a method for using a discharge-type turnover box: Before unloading, such as Figure 3 As shown, the second crossbar 25 is supported on the support part 34 of the hook 32; the slide cylinder 63 and the slide rod 65 are supported on the support member 15; the vertical rod 53 is set vertically. During unloading, the lifting equipment lifts container 1, such as... Figure 4 As shown, the operator picks up the handle 67 of the slide bar 65, causing the slide bar 65 to rotate horizontally via the first rotating shaft 61, and then vertically via the second rotating shaft 62, so that the short horizontal bar 66 is inserted between the pulling part 58 and the vertical bar 53. Pulling the handle 67 and the slide bar 65 causes the short horizontal bar 66 to pull the pulling part 58, as shown. Figure 5 As shown, pulling the pulling part 58 and the upper part of the vertical rod 53 away from the box body 1 causes the strip hole 56 of the first inclined rod 55 to rotate upward. The protrusion 35 slides in the strip hole 56, which in turn causes the first horizontal rod 3 and the hook 32 to rotate. The hook 32 moves away from the second horizontal rod 25, and the second horizontal rod 25 loses support. The self-unloading plate 2 flips downward, thereby opening the bottom of the box body 1, and the material inside the box body 1 falls downward. Pulling the pulling part 58 and the upper part of the vertical rod 53 further away from the box body 1 until the pulling part 58 rotates too much with the vertical rod 53, the short horizontal rod 66 can pass over the upper end of the pulling part 58. Then, the vertical rod 53 is quickly pulled back to its original position by the tension spring 41, and the connecting protrusion 54 of the vertical rod 53 hits the horizontal sleeve 42.

[0033] After unloading, the lifting equipment lowers the box 1, and the wheel 24 of the self-unloading plate 2 contacts the ground. The self-unloading plate 2 drives the second crossbar 25 to flip up together. The second crossbar 25 pushes open the bottom of the support part 34 until it returns to the top of the support part 34, thereby closing the bottom of the box 1.

[0034] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
