Description

Technical Field

[0001] This utility model relates to the technical field of equipment for converting dry bulk cargo transportation modes at wharves, and in particular to a coal loading equipment based on a direct truck-ship loading mode. Background Technology

[0002] In traditional ship loading operations, material can only be retrieved by large equipment within the process line, such as bucket wheel stacker-reclaimers and unloading machines, and then transported via belt conveyors. Therefore, it can only utilize the fixed stockpile within the original design and lacks flexibility.

[0003] Storage yards or off-site storage areas without automated loading lines cannot utilize these lines for loading onto ships. Instead, they must use double-axle dump trucks in conjunction with loaders and other mobile equipment for road transport. The materials are then transported to the North Yard gantry crane terminal, where the cranes retrieve the materials and load them onto the ships.

[0004] Compared to conveyor belt transportation, road transport has higher operating costs, higher human resource costs, greater difficulty in production scheduling, lower cargo transfer efficiency, and extremely low loading efficiency.

[0005] The process line involves picking up and loading materials onto ships, but the source of the materials for loading is singular and fixed, and can only be obtained from the originally designed fixed cargo yard. The fixed and rigid model makes it impossible to utilize other cargo yards for cargo turnover.

[0006] The loading efficiency of gantry cranes for transporting trucks to ships is highly dependent on the skill level of the crane operators, fluctuating significantly across different shifts and time periods, and is also greatly affected by weather conditions, hindering overall production planning and scheduling. Furthermore, each gantry crane requires a loader to assist with loading, and after transfer, the goods are unloaded at the freight yard before being handled by the crane; the process is complex, resulting in significant waste of human resources and low efficiency. The loading capacity of gantry cranes is only 18 to 25 tons, and due to the limited space in the freight yard, even with multiple gantry cranes operating simultaneously, their transport efficiency is extremely low compared to a conveyor belt system transporting 3000 tons per hour.

They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0027] like Figures 1 to 5 As shown, a coal loading device based on a direct truck-ship loading mode includes a material receiving hopper 6. A replaceable modular wear-resistant layer 602 is laid inside the material receiving hopper. The modular wear-resistant layer is a modular wear-resistant plate that is attached to the inner wall of the material receiving hopper. The modular wear-resistant plate is made of non-adhesive polyethylene material.

[0028] The dual-axle dump truck automatically unloads materials into the receiving hopper, where they slide smoothly down the modular wear-resistant plates. The receiving hopper is also equipped with a receiving vibration motor, which vibrates to accelerate the material's descent.

[0029] A vibrating feeder 5 is provided below the material receiving hopper 6. The vibrating feeder includes a feeding bin that can feed materials at a uniform speed. The feeding bin includes a horizontally arranged feeding cylinder 502. A vertically arranged guide cylinder 501 is provided at the discharge end of the feeding cylinder. A dropping cylinder 601 is provided below the material receiving hopper. A receiving port is opened on the top wall of the feeding cylinder, which is directly opposite to the dropping cylinder. The inner diameter of the receiving port is larger than the outer diameter of the dropping cylinder. The dropping cylinder extends into the receiving port. An elastic connector 8 is provided between the dropping cylinder and the feeding cylinder. The elastic connector includes four connecting springs 801 evenly distributed around the circumference of the dropping cylinder. The top of the connecting spring is vertically connected to the lower outer wall of the material receiving hopper. A spring hanging ring 802 is provided at the lower part of the connecting spring. An arc-shaped mounting plate is provided on the upper outer wall of the feeding cylinder along the circumference. A lower hanging ring 803 is provided on the arc-shaped mounting plate that is connected to the spring hanging ring. The connecting spring is always in a suspended state.

[0030] A flexible baffle assembly 9 is provided between the material receiving hopper and the feeding cylinder. The flexible baffle assembly is set on the annular gap between the material dropping cylinder and the material receiving port. The flexible baffle assembly includes an annular flexible baffle 901, which wraps around the annular gap in the circumferential direction. The circumferential dimension of the annular flexible baffle is always larger than the outer circle dimension of the annular gap.

[0031] The feed cylinder 502 has an inclined end block plate at its feed end. Several bin wall vibration motors 503 are located at one end of the feed cylinder near the material receiving hopper. There are two bin wall vibration motors, symmetrically arranged along both sides of the feed cylinder wall.

[0032] When the material falls into the feeding cylinder 502 through the receiving port along the discharge cylinder, the bin wall vibration motor 503 is started to vibrate at a uniform speed, so that the material moves in a uniform linear motion along the inner wall of the feeding cylinder, and the material is fed at a uniform speed.

[0033] During uniform vibration, the connecting spring vibrates at the same frequency as the silo wall vibration motor, and the annular gap between the discharge cylinder and the receiving port provides space for vibration movement and buffering.

[0034] The annular flexible baffle remains in a shielding state throughout the vibration process. This ensures that material does not leak outside the feed cylinder while achieving efficient vibration.

[0035] The lower end of the feed cylinder 501 is provided with a belt conveyor hopper 3, which extends into the belt conveyor hopper. The lower end of the belt conveyor hopper is provided with a discharge port, and the high-level belt conveyor 1 is located directly below the discharge port. The belt conveyor hopper is a cone-shaped feed bin 301 with an upward opening. The discharge port is located at the lower part of the cone-shaped feed bin. A flexible baffle 323 is provided around the discharge port in a circumferential direction. A locking connecting plate 321 is provided between the flexible baffle and the cone-shaped feed bin. The upper part of the locking connecting plate is provided with a locking hole. The wall of the cone-shaped feed bin is provided with a fixing hole corresponding to the locking hole. Locking bolts 322 are inserted into the locking hole and the fixing hole. Locking nuts are fitted on the bolts. The lower part of the locking connecting plate is connected to the outer wall of the flexible baffle.

[0036] The flexible baffle 323 serves as a conical guide, ensuring that the material falls along the flexible baffle.

[0037] The high-level belt conveyor 1 includes a corrugated sidewall conveyor belt 101 arranged inclined from bottom to top. One end of the corrugated sidewall conveyor belt is designated as a drive end 103, with a drive motor and a drive roller at the shaft end. The other end is designated as a driven end 102, with a driven roller. A pressure roller is provided on the upper surface of the bearing surface of the corrugated sidewall conveyor belt, and several evenly distributed idler rollers are provided on the lower surface of the bearing surface. A redirecting roller is provided on the lower surface of the non-bearing surface of the corrugated sidewall conveyor belt. Strip baffles 4 are provided on both sides of the discharge port, arranged along the direction of the high-level belt conveyor.

[0038] The strip baffle 4 extends along the direction of the corrugated side conveyor belt, and the material falls completely onto the corrugated side conveyor belt. The drive motor 1 starts and drives the drive roller to rotate in one direction, and the material is continuously conveyed along the corrugated side conveyor belt.

[0039] The high-level belt conveyor 1 is located directly below the drive end of the process line high-level belt conveyor 7. The material at the top of the high-level belt conveyor is transferred to the process line high-level belt conveyor, and a gravity hopper is located below the process line high-level belt conveyor for unloading.

[0040] There are four material receiving hoppers 6, each with a feeding bin below it. Below each feeding bin is a corresponding belt conveyor hopper 3. Below each belt conveyor hopper is a high-level belt conveyor and a large-level belt conveyor 7 that connects to the high-level belt conveyor for material transfer. This forms a series of combined conveyor lines that simultaneously transport large quantities of material at a uniform speed and stability.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
