Description

Technical Field

[0001] This utility model relates to the technical field of unloading devices, and specifically to an unloading device. Background Technology

[0002] In industries such as metallurgy, mining, and chemicals, a large amount of iron-containing waste is inevitably generated during the production process. The iron-containing waste is generally stored through waste collection devices. When the waste collection devices are full, the waste is unloaded from the collection devices manually or mechanically and transported to other processing locations.

[0003] For example, CN210589944U discloses a double-opening leak-proof unloading hopper, which includes a hopper body, a discharge port at the bottom of the hopper body, and two double-opening gates at the bottom of the hopper body for closing the discharge port. A power device for opening and closing the gates is fixedly installed on the outer surface of the hopper body. The hopper temporarily stores materials to be unloaded. After the materials are discharged into the hopper, the gates can be opened to allow the materials in the hopper to be loaded onto vehicles for transfer.

[0004] However, when materials are temporarily stored inside the discharge hopper, the existing system relies solely on the power unit to keep the gate closed. The gate lacks a reliable locking mechanism after closing, making it susceptible to loosening due to material pressure or vibration, potentially leading to accidental opening and posing a safety hazard. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a discharge device to solve the technical problem that the gate in the prior art lacks a reliable locking mechanism after closing, which makes it easy to loosen due to material pressure or vibration, leading to accidental opening and posing certain safety hazards.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a material unloading device, including: a material unloading body, a material unloading gate, and a locking mechanism. The material unloading body has a material unloading cavity inside, and a material unloading port communicating with the material unloading cavity is formed on one side. The material unloading gate includes two gate plates and at least two limiting members. The two gate plates are symmetrically arranged at the material unloading port and can move relative to each other to open or close the material unloading port. The at least two limiting members are respectively connected to the two gate plates. The locking mechanism is installed on the material unloading body and has a locking end. When the gate plates close the material unloading port, the locking end can lock or unlock the at least two limiting members.

[0007] In some embodiments, one side of the limiting member and the mating edge of the gate are located on the same plane. When the two gates close the discharge port, the corresponding two limiting members fit together. The locking end has a groove that cooperates with the two limiting members.

[0008] In some embodiments, the cross-sectional area of ​​the slot gradually increases from its bottom to its opening, and the width of the bottom of the slot is equal to the thickness of the two limiting members.

[0009] In some embodiments, the limiting member includes a U-shaped plate, the side of which is connected to the gate. When the two gates close the discharge port, the U-shaped openings of the corresponding two U-shaped plates are in opposite directions and their sides are in contact.

[0010] In some embodiments, the locking mechanism includes a rotating arm and a limiting block. The rotating arm is rotatably mounted on the unloading body via a mounting base, and the limiting block is mounted on one end of the rotating arm. The rotation of the rotating arm can drive the limiting block to move toward the unloading port. When the gate closes the unloading port, the rotation of the rotating arm can drive the limiting block to move to cooperate with the limiting member.

[0011] In some embodiments, the locking mechanism further includes a rotary drive component, which is mounted on the unloading body and has its output end connected to the rotary arm for driving the rotary arm to rotate, thereby moving the limiting block to a position that cooperates with the limiting component.

[0012] In some embodiments, the locking mechanism is provided in two sets, and the two sets of locking mechanisms are respectively provided at both ends of the gate plate docking position, and corresponding limiting members are provided on both sides of the two gate plates.

[0013] In some embodiments, toothed plates are provided on the inner sides of the mating edges of the two gates, and the two toothed plates mesh with each other when the gate closes the discharge port.

[0014] In some embodiments, a waterproof sealing gasket is provided in the groove of each toothed plate.

[0015] In some embodiments, the unloading device further includes an unloading drive mechanism connected to the gate, which drives the gate to move to open or close the unloading port.

[0016] Compared with the prior art, the unloading device provided by this utility model, by setting up an unloading body, an unloading gate and a locking mechanism, and setting a limiting member on the outer side of the gate's mating edge, cooperates with the locking end of the locking mechanism. When the gate closes the unloading port, the locking end of the locking mechanism moves relative to the unloading port and locks with the limiting member, thereby fixing the relative position of multiple limiting members, effectively restricting the relative movement of the two gates, ensuring that the unloading port remains closed, and the gate is not easily loosened due to material pressure or vibration. This effectively solves the problem that the gate of the unloading device in the prior art is easily loosened due to material pressure or vibration. Attached Figure Description

[0019] 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.

[0020] To address the technical problem that gates lack a reliable locking mechanism after closing, making them prone to loosening due to material pressure or vibration, which could lead to accidental opening and pose certain safety hazards, this utility model provides a discharge device that can effectively limit the relative movement of the two gates, ensuring that the discharge port remains closed. This effectively solves the problem that gates in existing discharge devices are prone to loosening due to material pressure or vibration.

[0021] It should be noted that the unloading device described in this utility model is used for, but not limited to, iron-containing waste materials. For ease of explanation, this utility model only uses the application of the unloading device to iron-containing waste materials as an example. The principle of the unloading device in unloading other types of materials is essentially the same as that in unloading iron-containing waste materials, and will not be described in detail here.

[0022] Please see Figure 1 and Figure 2 The unloading device includes: an unloading body 1, an unloading gate 2, and a locking mechanism 3. The unloading body 1 has an unloading cavity inside, and an unloading port communicating with the unloading cavity is formed on one side. The unloading gate 2 includes two gate plates 21 and at least two limiting members 22. The two gate plates 21 are symmetrically arranged at the unloading port and can move relative to each other to open or close the unloading port. The at least two limiting members 22 are respectively connected to the two gate plates 21. The locking mechanism 3 is installed on the unloading body 1 and has a locking end. When the gate plate 21 closes the unloading port, the locking end can lock or unlock the at least two limiting members 22.

[0023] In this design, the unloading body 1 is equipped with an unloading chamber and an unloading port. The iron-containing scrap to be unloaded is temporarily stored in the unloading chamber. The unloading port is opened and closed by a gate. During the unloading process, the unloading port can be easily opened or closed by driving the gate plate 21 to facilitate the unloading operation. Through the limiting members 22 on the gate plate 21 and the locking mechanism on the unloading body 1, when the gate plate 21 closes the unloading port, the locking end moves relative to the unloading port, locking or unlocking at least two limiting members 22. This fixes the relative positions of the multiple limiting members 22, effectively restricting the relative movement of the two gate plates 21, ensuring the unloading port remains closed, and effectively preventing the gate plate 21 from accidentally opening due to impact or vibration from the iron-containing scrap during the unloading process.

[0024] Preferably, in this embodiment, the unloading body 1 is an unloading hopper, and the bottom sides of the unloading hopper are set as inclined surfaces that gradually slope from top to bottom towards the middle. The unloading port is located at the bottom of the unloading hopper, which facilitates the collection of iron-containing waste and its discharge from the unloading port. The side walls of the unloading hopper and the outer wall of the gate 21 are provided with reinforcing ribs 12, which can enhance the structural strength of the unloading hopper and the gate 21 and improve their service life.

[0025] Furthermore, in order to enhance the locking effect of the gate plate 21, in some possible embodiments, the locking mechanism 3 is provided in two sets. The two sets of locking mechanisms 3 are respectively installed on the vertical sidewalls on both sides of the unloading hopper and respectively set at both ends of the gate plate 21 docking position. Each gate plate 21 has a limiting member 22 on both sides. The two limiting members 22 located on the same side of the gate plate 21 correspond to each other and are used to cooperate with the locking end of one locking mechanism 3. Thus, when the locking end moves, it can lock and cooperate with the two limiting members 22 at the same time, which further improves the locking stability and reliability of the gate plate 21.

[0026] To achieve the locking engagement between the limiting member 22 and the locking mechanism 3, please refer to... Figures 1 to 3 In some possible embodiments, one side of the limiting member 22 is on the same plane as the mating edge of the gate 21 on which it is located. Two limiting members 22 located on the same side of the two gates 21 correspond to each other. When the two gates 21 close the discharge port, the corresponding two limiting members 22 are in contact with each other. The locking end has a groove 321 that mates with the two limiting members 22. The movement of the locking end has a locked position and an unlocked position. In the locked position, the groove 321 is engaged with the outside of the two limiting members 22, locking the two limiting members 22 together and preventing the gate 21 from opening. In the unlocked position, the groove 321 separates from the limiting member 22, allowing the gate 21 to move and open the discharge port.

[0027] Further, please refer to Figures 1 to 4 To facilitate the connection between the slot 321 and the limiting member 22, in some possible embodiments, the cross-sectional area of ​​the slot 321 gradually increases from its bottom to its opening. This design allows the opening of the slot 321 to be flared, making it easier for the limiting member 22 to engage or disengage from the slot 321. Furthermore, the width of the bottom of the slot 321 is equal to the thickness of the two limiting members 22. When the locking end is in the locked position, the bottom of the slot 321 is in close contact with the two limiting members 22, providing a stable locking force and further preventing the limiting members 22 from shaking or disengaging during the locking process.

[0028] In one embodiment, please refer to Figures 1 to 4The limiting component 22 includes a U-shaped plate 221, and the locking mechanism 3 includes a rotating arm 31 and a limiting block 32. Specifically, the side of the U-shaped plate 221 is connected to the gate 21. When the two gates 21 close the discharge port, the U-shaped openings of the corresponding two U-shaped plates 221 are in opposite directions and one side is in contact with each other. The rotating arm 31 is rotatably mounted on the vertical side wall of the discharge body 1 via the mounting base 11. The central axis of the rotating shaft of the rotating arm 31 is perpendicular to the mating surface of the gate 21. The limiting block 32 is fixedly mounted on one end of the rotating arm 31, and a flared groove 321 is provided on the side near the discharge port to form a locking end. The rotation of the rotating arm 31 can drive the limiting block 32 to move toward the discharge port. When the gate 21 closes the discharge port, the rotating arm 31 is rotated so that the groove 321 on the limiting block 32 is engaged with the outside of the two U-shaped plates 221, thereby locking the two gates 21. At this time, the rotating arm 31 cannot continue to rotate, thus achieving locking. When it is necessary to open the discharge port, drive the rotating arm 31 to rotate in the opposite direction, causing the limit block 32 to move away from the discharge port, so that the slot 321 separates from the U-shaped plate 221, and then the gate 21 can be moved to open the discharge port.

[0029] Furthermore, to improve the stability of the engagement between the U-shaped plate 221 and the limiting block 32, the locking mechanism 3 also includes a rotary drive component 33. The rotary drive component 33 is mounted on the unloading body 1, and its output end is connected to the rotating arm 31. It drives the rotating arm 31 to rotate, thereby moving the limiting block 32 to a position that engages with the limiting member 22. The rotary drive component 33 not only automatically drives the rotating arm 31 to rotate, enabling automatic switching between the locking and unlocking positions, but also provides a locking force to restrict the rotation of the rotating arm 31 when the limiting block 32 is connected to the limiting member 22, further enhancing the stability and reliability of the locking mechanism 3.

[0030] Specifically, the rotary drive component 33 can be driven by electricity, pneumatics, or hydraulics. Preferably, in this embodiment, the rotary drive component 33 includes a first cylinder 331. One end of the first cylinder 331 is rotatably mounted on the unloading body 1 via a first rotating seat 332. Its telescopic drive end is rotatably connected to the top end of the rotating arm 31, and the bottom end of the rotating arm 31 is connected to a limiting block 32. The telescopic movement of the first cylinder 331 can be controlled by a control signal to achieve rapid opening and closing of the unloading port. After the unloading operation is completed, by controlling the telescopic end of the first cylinder 331 to retract, the rotating arm 31 is driven to rotate, thereby causing the slot 321 on the limiting block 32 to separate from the U-shaped plate 221. At this time, the gate 21 can be moved to open the unloading port to achieve unloading. After closing the unloading port, the telescopic end of the first cylinder 331 is controlled to extend again, pushing the rotating arm 31 to rotate in the opposite direction, so that the slot 321 on the limiting block 32 engages with the outer side of the two U-shaped plates 221 to achieve locking. By setting the rotary drive component 33, the gate 21 can be easily driven without manual operation, further improving the automation level of the unloading process.

[0031] Of course, in other possible embodiments, the locking mechanism 3 can also take other forms. For example, the locking mechanism 3 can also include a sliding plate slidably disposed on the unloading body 1 and a sliding drive member connecting the sliding plate. One side of the sliding plate is provided with a locking block that engages with the limiting member 22. The sliding drive member drives the sliding plate to slide relative to the unloading body 1. When the gate 21 closes the unloading port, the locking block can slide to the position where it engages with the limiting member 22, thereby locking the two gates 21. The sliding drive member can also be electrically driven, pneumatically driven, or hydraulically driven to achieve automatic engagement and disengagement of the locking block and the limiting member 22.

[0032] To enable the gate 21 to open and close the discharge port, in some possible embodiments, please refer to... Figure 1 It is also equipped with a discharge drive mechanism 4, which is connected to the gate 21 and is used to drive the gate 21 to move to open or close the discharge port.

[0033] Preferably, please refer to Figure 1 , Figure 5 and Figure 6In this embodiment, the unloading drive mechanism 4 includes a second cylinder 41, a second rotating seat 42, and a third rotating seat 43. One end of the second cylinder 41 is rotatably mounted on the unloading body 1 via the second rotating seat 42, and its telescopic drive end is rotatably connected to the third rotating seat 43. The third rotating seat 43 is fixedly connected to the gate 21, and both ends of the gate 21 are rotatably connected to the unloading body 1. When it is necessary to close the unloading port, the telescopic drive end of the second cylinder 41 extends, pushing the third rotating seat 43 and the gate 21 connected to it to rotate relative to the unloading body 1, causing the gate 21 to gradually close the unloading port. When unloading is required, the telescopic drive end of the second cylinder 41 is controlled to retract, driving the third rotating seat 43 and the gate 21 to rotate in the opposite direction until the gate 21 opens the unloading port. Through the telescopic action of the second cylinder 41, the opening and closing of the gate 21 can be easily controlled, realizing rapid operation of the unloading port.

[0034] Of course, in other possible embodiments, the gate 21 can also be operated manually, for example, by manually rotating a lever or manually pushing and pulling a mechanism. The gate 21 can be moved by manually rotating the lever or manually pushing and pulling the mechanism to open or close the discharge port. The discharge drive mechanism 4 can also use other drive elements, such as a motor drive.

[0035] To improve the valve's sealing performance, please refer to [link / reference]. Figure 7 In some possible embodiments, toothed plates 23 are provided on the inner sides of the mating edges of both gates 21. The toothed plates 23 have a pointed tooth structure. When the gates 21 close the discharge port, the two toothed plates 23 mesh with each other. The toothed structure has a larger alignment tolerance and more reliable sealing. In addition, waterproof sealing gaskets are embedded in the grooves of the toothed plates 23. When the gate is closed, the toothed plates 23 interlock, and the waterproof sealing gaskets are deformed under pressure to fill the gaps. The waterproof sealing gaskets on the toothed plates 23 can be sequentially installed at the connection positions of the toothed plates 23, thereby enhancing the sealing performance between the two gates 21.

[0036] Furthermore, the top of the pointed tooth portion of the toothed plate 23 is provided with a guide slope. The guide slope gradually slopes outward and downward from the middle position of the pointed tooth. The guide slope is used to guide the iron-containing waste material remaining in the tooth groove to the top of the toothed plate 23 when the gate 21 closes the discharge port, so as to avoid the iron-containing waste material remaining between the two toothed plates 23 and affecting the sealing effect of the gate 21.

[0037] To better understand this utility model, the following is combined with... Figures 1 to 7The technical solution of this utility model is described in detail as follows: When it is necessary to close the discharge port, the second cylinder 41 is activated, and the telescopic drive end of the second cylinder 41 extends, pushing the third rotating seat 43 and the gate 21 fixedly connected to it to rotate relative to the discharge body 1. The two gates 21 gradually close during rotation until the gates 21 completely close the discharge port. At this time, the first cylinder 331 is activated, and the telescopic drive end of the first cylinder 331 extends, driving the rotating arm 31 to rotate. During the rotation of the rotating arm 31, the limiting block 32 on it gradually approaches the discharge port until the slot 321 on the limiting block 32 engages with the outer side of the two U-shaped plates 221, providing a stable locking force.

[0038] When it is necessary to open the discharge port for unloading, the first cylinder 331 is activated to retract its telescopic drive end, causing the rotating arm 31 to rotate in the opposite direction. During the rotation of the rotating arm 31, the limiting block 32 gradually moves away from the discharge port until the slot 321 separates from the U-shaped plate 221. At this time, the second cylinder 41 can be activated to retract its telescopic drive end, causing the third rotating seat 43 and the gate 21 to rotate in the opposite direction. During the rotation of the gate 21, the discharge port is gradually opened, and the iron-containing scrap can be discharged from the discharge port.

[0039] This invention comprises a discharge body 1, a discharge gate 2, and a locking mechanism 3. Limiting elements 22 are installed on the outer side of the gate 21's mating edge. These limiting elements 22, in conjunction with the locking end of the locking mechanism 3, allow the locking end of the locking mechanism 3 to move relative to the discharge port when the gate 21 closes, locking in place with the limiting elements 22. This effectively restricts the relative movement of the two gates 21, ensuring the discharge port remains closed. The gate 21 is less prone to loosening due to pressure or vibration from iron-containing waste, effectively solving the problem of gates in existing discharge devices easily loosening due to pressure or vibration from iron-containing waste. Furthermore, the use of a toothed plate 23 and a waterproof sealing gasket further improves the sealing performance of the discharge device, preventing leakage of iron-containing waste. The invention offers advantages such as simple structure, convenient operation, and high safety and reliability.
