Description

Technical Field

[0001] This utility model relates to the field of bulk-to-container loading technology, specifically to a bulk-to-container loading and unloading guiding device. Background Technology

[0002] Bulk-to-container transport is a multimodal transport method that loads traditional bulk goods such as coal, coke, and bauxite into containers. Through standardized loading, it achieves seamless connection of the transport chain. This mode of transport can effectively reduce environmental pollution and cargo damage accidents, and improve reliability and economy. At present, this model is widely used in port and railway transportation and has become an important measure to promote the upgrading of bulk commodity transportation.

[0003] Currently, after bulk cargo is unloaded from trucks, it is first transferred by belt conveyor to a high-level buffer silo. The material then falls from the buffer silo down a telescopic chute into the container. On the one hand, after the bulk cargo falls into the container, the material pile tends to form a cone shape with a high center and low edges, making it impossible to distribute the material evenly around the container and affecting the loading effect. On the other hand, the drop will generate a large impact force, which will not only cause some impact damage to the container, but also cause serious impact damage to the material (such as coke). As a result, the coke breakage rate will increase significantly in the bulk-to-container transfer process, which will greatly affect the quality of the product. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a bulk-to-container loading and unloading guide device that facilitates the uniform distribution of bulk materials and reduces the damage rate of goods during the bulk-to-container loading and unloading process.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a bulk-to-container loading and unloading guide device, which is installed on the chute section at the end of the telescopic chute, including an installation sleeve fixedly fitted on the chute section at the end of the telescopic chute, and a guide cone connected to the installation sleeve through a support arm, the guide cone being located at the lower center of the chute section at the end of the telescopic chute.

[0006] As a preferred technical solution, the bottom edge of the mounting sleeve is higher than the bottom edge of the end pipe section of the telescopic chute.

[0007] As a preferred technical solution, the guide cone is a frustum of a pyramid or a frustum of a cone.

[0008] As a preferred technical solution, the support arm and the mounting sleeve are detachably connected.

[0009] As a preferred technical solution, the mounting sleeve is equipped with two pre-storage buffer valve plates that can be opened and closed, and the two pre-storage buffer valve plates are engaged and driven; one of the pre-storage buffer valve plates is connected to an opening and closing drive mechanism.

[0010] As a preferred technical solution, the pre-storage buffer valve plate includes two opposing sector plates, a buffer plate is provided between the bottoms of the two sector plates, a baffle plate is provided on the outer side of the buffer plate, and a clearance groove for clearance mounting sleeve is formed above the baffle plate; a gear for meshing transmission is provided at the top of the sector plate.

[0011] As a preferred technical solution, the buffer plate includes a substrate, and an elastic plate is covered on the substrate.

[0012] As a preferred technical solution, the opening and closing drive mechanism is a hydraulic cylinder.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] (1) By setting an installation sleeve on the end section of the telescopic chute, the installation sleeve is connected to the guide cone through the support arm. The guide cone is located at the center below the end section of the telescopic chute. In this way, the bulk cargo will be evenly distributed in the container by the guiding effect of the guide cone during the unloading and loading process, thus ensuring a good loading effect.

[0015] (2) By installing two openable and closeable pre-storage buffer valve plates on the chute section at the end of the telescopic chute, during the bulk-to-container loading operation, the bulk materials can be unloaded into the telescopic chute first, and then the telescopic chute descends to carry the bulk materials into the container. The traditional high-level impact unloading is changed to pre-storage sequential buffer unloading. The entire loading process of the bulk materials from the buffer silo along the telescopic chute to the container is continuous and achieves impact-free unloading due to pre-storage buffer. There will be no impact force due to the drop factor, which greatly reduces the breakage rate of bulk materials (especially coke) and effectively avoids impact damage to the container.

[0016] (3) When the telescopic chute is at the upper limit and the pre-storage buffer valve plate is closed, it can effectively buffer and pre-store the bulk material; when the telescopic chute descends to the lower limit and the pre-storage buffer valve plate is opened to unload the material, it will not affect the vertical discharge speed of the bulk material, nor will it affect the loading efficiency. The structure is unique and the operation is flexible and reliable. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0026] like Figures 1 to 4 As shown, the bulk-to-container loading and unloading guiding device is installed on the chute section at the end of the telescopic chute 1. It includes an installation sleeve 2 fixedly fitted onto the chute section at the end of the telescopic chute 1. For ease of installation, the installation sleeve 2 is preferably square. The installation sleeve 2 is connected to a guide cone 4 via four support arms 3. The guide cone 4 is located at the lower center of the chute section at the end of the telescopic chute 1. Material falling from the telescopic chute is evenly distributed to all directions by the guide cone. In this embodiment, the guide cone 4 is a frustum pyramid shape, but it can also be a frustum cone shape; both are within the protection scope of this utility model.

[0027] refer to Figure 1 To facilitate the installation and fixing of the support arm 3, the bottom edge of the mounting sleeve 2 is higher than the bottom edge of the end pipe section of the telescopic chute 1. The support arm 3 is preferably detachably connected to the mounting sleeve 2, which makes it easier to disassemble, replace, and maintain the guide cone 4.

[0028] refer to Figure 1 and Figure 3The mounting sleeve 2 is equipped with two openable and closable pre-storage buffer valve plates 5, which mesh and drive each other. One of the pre-storage buffer valve plates 5 is connected to an opening and closing drive mechanism 6, which is preferably a hydraulic cylinder, ensuring reliable and stable operation. When the telescopic chute 1 is at its upper limit and the pre-storage buffer valve plate 5 is closed, effective buffering and pre-storage of bulk materials can be achieved. When the telescopic chute 1 descends to its lower limit and the pre-storage buffer valve plate 5 opens for unloading, the vertical discharge speed of the bulk materials will not be affected, nor will the loading efficiency be affected. The structure is uniquely designed and operates flexibly and reliably.

[0029] refer to Figure 2 and Figure 5 The pre-storage buffer valve plate 5 includes two opposing sector plates 51, with a buffer plate 52 positioned between the bottoms of the two sector plates 51. The buffer plate 52 includes a steel base plate 521 covered with a rubber elastic plate 522. During unloading, bulk materials fall from a limited height from the buffer hopper onto the elastic plate 522, avoiding impact from large drops and significantly reducing the breakage rate of bulk materials (especially coke) due to the elastic buffering effect. A baffle plate 53 is provided on the outer side of the buffer plate 52, with an clearance groove 54 formed above the baffle plate 53. This ensures effective material storage and prevents interference with the mounting sleeve 2 when rotated open. A gear 55 for meshing transmission is provided at the top of the sector plates 51. When the pre-storage buffer valve plate 5 on one side is driven to rotate by the opening and closing drive mechanism 6, the pre-storage buffer valve plate 5 on the other side can be driven to rotate synchronously in the opposite direction through the meshing transmission gear 55, thereby realizing the opening and closing of the two pre-storage buffer valve plates 5.

[0030] During bulk-to-container loading operations, bulk cargo can first be unloaded into the telescopic chute 1, and then the telescopic chute 1 descends, carrying the bulk cargo into the container 7. When the telescopic chute 1 carrying the bulk cargo descends to its lower limit, the pre-stored buffer valve 5 is opened to begin the unloading operation. The entire loading process of the bulk cargo along the telescopic chute to the container is continuous and, due to the pre-stored buffer, achieves impact-free unloading, completely eliminating impact forces caused by drop factors. (Reference) Figure 6 During the unloading and loading process, bulk cargo will be evenly distributed in all directions within the container 7 by the guiding action of the guide cone 4, and the material level will always remain relatively level, thus ensuring a good loading effect.

[0031] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
