Description

Technical Field

[0001] This utility model relates to the technical field of bulk cargo loading and unloading equipment at port terminals, specifically a bulk cargo hopper. Background Technology

[0002] Port terminals are the core hubs of global trade, playing a decisive role in the smooth operation of international trade with their powerful cargo loading, unloading, storage, and transshipment capabilities. As a key piece of terminal equipment, hoppers, through efficient coordination with conveyor systems and loading / unloading machinery, can significantly improve cargo handling efficiency.

[0003] Traditional hopper loading and unloading processes typically involve a crane → hopper → truck, which cannot achieve continuous unloading and suffers from low efficiency and non-compliance with environmental standards. This invention adopts a loading and unloading process of "crane → hopper → intermediate belt conveyor → rear conveyor belt," which significantly improves loading and unloading efficiency compared to traditional methods.

[0004] When the hopper supplies material to the rear conveyor belt, the intermediate belt of the hopper must not only overcome the problem of long-distance material transportation, but also meet the requirement that the intermediate belt can perform loading and unloading operations on different rear conveyor belts.

[0005] Furthermore, when the hopper passes the transfer tower, the conveyor belt in the middle of the hopper needs to retract and extend to avoid collisions with the transfer tower and causing safety accidents. Meeting these requirements necessitates a conveyor belt extension / retraction stroke exceeding 10 meters, which is technically difficult to implement.

[0006] Patent No. CN116654657A proposes a movable hopper for a belt conveyor. This hopper can push the intermediate belt conveyor outward to expand the conveying distance of the hopper and realize the separate feeding of different conveyor belts under different working conditions. It solves the problem of interference with large spans and transfer station facilities. However, its structure is too complicated, requiring the addition of belt conveyor tracks, belt conveyor wheels, anchoring devices, pressure rollers, etc., resulting in high manufacturing costs. In addition, there is a risk of the hopper tipping over when the intermediate belt conveyor is pushed outward.

[0007] To address the problems faced by existing technologies, this utility model proposes a hopper consisting of a hopper, an intermediate belt conveyor, and a rotating belt. It is capable of large-span continuous loading and unloading operations and feeding different conveyor belts under different working conditions, thereby improving the unloading efficiency of the dock and significantly reducing the manufacturing cost of the hopper. Utility Model Content

[0008] This utility model addresses the problems of low loading and unloading efficiency and limited feeding conditions of traditional hoppers by providing a new type of hopper that achieves continuous loading and unloading operations over a long span through structural innovation and functional integration. It is suitable for various working conditions and can perform different conveyor belt feeding functions, thereby reducing the manufacturing cost of the hopper.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a bulk cargo hopper, including a hopper gantry, on which a hopper body, an intermediate belt conveyor, and a rotary belt conveyor are installed. The intermediate belt conveyor is installed at an incline on the hopper gantry, with its feed end located below the hopper body. The rotary belt conveyor is rotatably installed on the hopper gantry, with its feed end located below the output end of the intermediate belt conveyor, and its output end connected to the conveyor belt assembly of the dock transfer station. The intermediate belt conveyor is used to transport materials unloaded from the hopper body to the rotary belt conveyor, which then feeds the conveyor belt assembly of the dock transfer station.

[0010] The present invention is further configured such that the hopper gantry includes support legs, a gantry platform and a traction rod, and the two ends of the traction rod can be connected to other structures, and the connection form is not limited.

[0011] The present invention is further configured such that one end of the traction rod is connected to the outrigger and the other end is connected to a crane, so that when the crane moves by means of the traction rod, the entire hopper can be moved at the same time.

[0012] The present invention is further configured such that the hopper body is mounted on the gantry platform via a frame structure.

[0013] The present invention is further configured such that the rotating belt conveyor is located at the end of the gantry platform near the dock transfer station.

[0014] The present invention is further configured such that, in the working state, the rotating belt conveyor can rotate a certain angle to rotate the overall structure outward; in the non-working state, the rotating belt conveyor retracts inward to reduce the space occupied by the hopper in the horizontal direction.

[0015] The present invention is further configured such that the rotating belt conveyor includes a steering mechanism and a belt conveyor assembly, wherein the steering mechanism is mounted on a gantry platform and can drive the belt conveyor assembly to rotate.

[0016] The present invention is further configured such that the steering mechanism is a slewing bearing, and the belt conveyor assembly is mounted on the gantry platform via the slewing bearing.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution: Please refer to Figures 1-3 A bulk cargo hopper includes a hopper gantry 1, on which a hopper body 2, an intermediate belt conveyor 3, and a rotary belt conveyor 4 are mounted. The intermediate belt conveyor 3 is inclinedly mounted on the hopper gantry 1, with its feed end located below the hopper body 2. The rotary belt conveyor 4 is rotatably mounted on the hopper gantry 1, with its feed end located below the output end of the intermediate belt conveyor 3, and its output end connected to the conveyor belt assembly of the terminal transfer station. The intermediate belt conveyor 3 is used to transport materials unloaded from the hopper body 2 to the rotary belt conveyor 4, which then feeds the conveyor belt assembly of the terminal transfer station.

[0027] Please see Figures 1-3As one embodiment of the hopper gantry 1: the hopper gantry 1 includes support legs 11, gantry platform 12 and traction rod 13. The two ends of the traction rod 13 can be connected to other structures, and the connection form is not limited.

[0028] Specifically, one end of the traction rod 13 is connected to the outrigger 11, and the other end is connected to the crane. When the crane moves, the hopper can be driven to move as a whole.

[0029] Specifically, the hopper body 2 is installed on the gantry platform 12 via a frame structure.

[0030] Please see Figures 1-3 As one embodiment of the rotary belt conveyor 4: the rotary belt conveyor 4 is located at the end of the gantry platform 12 near the dock transfer station.

[0031] When in operation, rotating the belt conveyor 4 at a certain angle can rotate the entire structure outward;

[0032] When not in operation, the rotating belt conveyor 4 retracts inward to reduce the horizontal space occupied by the hopper. Please refer to [link / reference]. Figures 1-3 As one embodiment of the rotary belt conveyor 4: the rotary belt conveyor 4 includes a steering mechanism 41 and a belt conveyor assembly 42. The steering mechanism 41 is mounted on the gantry platform 12 and can drive the belt conveyor assembly 42 to rotate.

[0033] Please see Figures 1-3 As one embodiment of the steering mechanism 41: the steering mechanism 41 is a slewing bearing, the belt conveyor assembly 42 is mounted on the gantry platform 12 through the slewing bearing and is connected to an external drive system. The external drive system can be a motor or hydraulic motor, or an electric slewing bearing product can be directly used, and the motor and slewing bearing can be directly integrated into the design. The above are all existing structures or existing products, and can be flexibly selected as needed. This utility model will not elaborate further.

[0034] In summary, the working principle and specific workflow of this utility model are as follows:

[0035] The hopper is connected to the corresponding crane via a traction rod 13, and the crane pulls the entire hopper to the work area.

[0036] During operation, with the cooperation of the steering mechanism 41, the belt conveyor component 42 in the rotating belt conveyor 4 rotates outward. After the belt conveyor component 42 rotates at a certain angle according to the material working conditions, it forms a "connection" with the corresponding belt of the transfer station 100, so that the output end of the belt conveyor component 42 is matched with the loading position of the corresponding belt of the transfer station 100.

[0037] Then, the crane unloads the material into the hopper body 2, and the material is discharged into the intermediate belt conveyor 3 through the hopper body 2;

[0038] The intermediate belt conveyor 3 is arranged at an angle. After transporting the material to the belt conveyor component 42 in the corresponding rotating belt conveyor 4, the belt conveyor component 42 in the rotating belt conveyor 4 sends the material to the corresponding conveyor belt in the transfer station 100 to realize the loading and unloading operation of the material.

[0039] After the loading and unloading operation is completed, the belt conveyor component 42 in the control hopper rotating belt conveyor 4 rotates inward and retracts, and is pulled away by the crane.

[0040] like Figure 3 As shown, in this utility model, when the hopper is unloading material under different working conditions, the rotation angle of the steering mechanism 41 is adjusted to change the docking position between the belt conveyor assembly 42 and the different conveyor belts of the transfer station 100, so as to realize diversified use conditions.

[0041] Taking a transfer station 100 equipped with two sets of conveyor belts—the first conveyor belt 101 and the second conveyor belt 102—as an example:

[0042] like Figure 3 As shown:

[0043] When the belt conveyor assembly 42 is docked with the first conveyor belt 101, it forms a first working state 1001;

[0044] When the rotation is adjusted and connected to the second conveyor belt 102, a second working state 1002 is formed;

[0045] It is in a non-working state 1000 when it rotates inward to retract.

[0046] In this utility model, the number of conveyor belts that connect with the transfer station 100 is not limited to two sets, and can be selected for installation according to the actual situation.
