Description

Technical Field

[0001] This utility model relates to the technical field of port bulk cargo loading and unloading equipment, and more specifically, to a high-efficiency and environmentally friendly bulk cargo bucket structure for a crane. Background Technology

[0002] As a core node in the global logistics chain, the efficiency of bulk cargo handling and environmental protection directly affect port operating costs, ship turnaround rates, and the quality of the surrounding ecological environment.

[0003] Currently, in traditional port bulk cargo loading and unloading operations, mainstream hopper equipment generally adopts a single-bucket structure design. Its limitations are mainly reflected in two aspects: "prominent bottleneck in operational efficiency" and "difficulty in meeting environmental performance standards." Specifically, the single-bucket structure can only load one transport vehicle or one conveyor belt at a time, resulting in a "single-thread" loading operation and low efficiency. Regarding environmental performance, during bulk cargo loading and unloading, material drop, impact, and wind forces generate a large amount of dust. Traditional hoppers only control dust through simple spraying or covering with tarpaulins, which cannot solve the following problems: First, spraying easily leads to excessive material moisture; second, covering with tarpaulins requires frequent manual opening and closing, which is cumbersome, has poor sealing, and results in a high dust escape rate, threatening the health of operators.

[0004] Therefore, how to provide a high-efficiency and environmentally friendly bulk cargo bucket structure with high loading and unloading efficiency, which can reduce dust emission concentration in the operating area, reduce air pollution and material loss has become a technical problem that urgently needs to be solved by those skilled in the art.

The efficient and environmentally friendly bulk cargo hopper structure disclosed in this utility model consists of a main frame assembly, a feeding channel, a dust removal mechanism, a dust removal grid, a double hopper mechanism, and a telescopic chute mechanism. All components are integrated through the main frame. The material to be loaded or unloaded is input from the feeding channel, falls into the double hopper mechanism after passing through the dust removal grid, and is finally unloaded onto a vehicle or drive belt through the telescopic chute mechanism, forming an integrated system of efficient operation and precise dust control, achieving a dual improvement in loading and unloading efficiency and environmental performance.For efficient operation, the bulk cargo hopper structure incorporates a double-hopper mechanism, which allows for parallel parking of two vehicles, significantly improving loading and unloading efficiency compared to traditional single-hopper structures.

The first stage utilizes the dust removal mechanism for negative pressure adsorption of dust. In this mechanism, a negative pressure fan is connected to the dust removal chamber. When the grab bucket unloads, the negative pressure fan activates, creating a negative pressure field within the dust removal chamber, drawing in dust escaping from the upper part of the hopper. The dust removal chamber is equipped with a filter cartridge assembly for dust adsorption. The collected dust is then directly filtered by a pulsed gas jet emitted from a pulse valve. The material falls into the hopper; secondly, the second-level strategy is to intercept dust through the dust removal grid. The material enters from the feeding channel, then passes through the dust removal grid into the double-hopper mechanism. The dust removal grid can intercept large particles and prevent some dust particles from overflowing. Finally, the third-level strategy for precise dust control is sealing and suppression. The material falls into the double-hopper mechanism and then exits from the telescopic chute mechanism. The telescopic chute mechanism can adjust the chute length according to the stacking height of the material pile to prevent the material from impacting the pile and causing dust to overflow. Furthermore, the telescopic chute mechanism is connected to the dust removal mechanism through the suction pipe. The suction pipe draws the dust from the telescopic chute mechanism into the dust removal box for negative pressure dust removal, further reducing dust overflow. Through the above multi-stage coordinated dust control, the dust emission concentration is reduced, precisely meeting environmental protection requirements. Therefore, the technical solution provided by this utility model, compared with the prior art, has high loading and unloading efficiency, can reduce the dust emission concentration in the working area, and reduce air pollution and material loss.

Compared with existing technologies, the technical solution provided by this utility model has high loading and unloading efficiency, can reduce dust emission concentration in the working area, and reduce air pollution and material loss.

[0027] The technical solution of this utility model will be specifically described below with reference to the embodiments: Specifically, in an embodiment of this utility model, the high-efficiency and environmentally friendly bulk material hopper structure further includes: an operation control mechanism 7 disposed on the main frame assembly 1; the operation control mechanism 7 is provided with an operation control system connected to the dust removal mechanism 3, the double hopper mechanism 5, and the telescopic chute mechanism 6; wherein, the operation control system includes: a human-machine interaction unit for manually inputting operation requirements; an operation mode switching unit for automatically matching valve opening, telescopic length of the central chute 604, and hopper collaborative operation mode according to operation requirements; and a fault early warning unit for real-time monitoring of key parameters of equipment operation, triggering audible and visual alarms when abnormalities occur, and recording alarm logs.

[0028] Specifically, in an embodiment of this utility model, the double-bucket mechanism 5 includes: a first bucket 501 disposed on the main frame assembly 1; a second bucket 502 symmetrically arranged alongside the first bucket 501; a feeder 503 disposed between the first bucket 501 and the second bucket 502; and an electro-hydraulic flat gate 504 disposed at the bottom of the first bucket 501 and the second bucket 502.

[0029] like Figure 4 , 5As shown, in this embodiment of the invention, the double-bucket mechanism 5 is used to improve loading and unloading efficiency. In this embodiment, the double-bucket mechanism 5 consists of a first bucket 501, a second bucket 502, a distributor 503, and an electro-hydraulic flat gate 504. The first bucket 501 and the second bucket 502 are symmetrically arranged side-by-side. The first bucket 501 and the second bucket 502 are linked to the port gate machine via the main frame assembly 1. The center-to-center distance between the two buckets is 3 to 4 meters, which is sufficient for two standard 2.5-meter-wide dump trucks. Parallel docking requirements; the electro-hydraulic flat gate 504 is installed at the bottom of the first bucket 501 and the second bucket 502. The gate opening is infinitely adjustable to adapt to the loading and unloading needs of different materials. Furthermore, the operation control system can switch between multiple operating modes such as "first bucket 501 unloading, second bucket 502 on standby", "first bucket 501 and second bucket 502 unloading simultaneously", and "first bucket 501 unloading, second bucket 502 replenishing". The distributor 503 is used to evenly divide the material so that it falls into the two buckets. In this embodiment, the independent and controllable dual-bucket design realizes "1 bucket = 2 operating units", supporting a dual-bucket loading mode, which greatly improves loading and unloading efficiency compared to traditional single-bucket operations. Furthermore, as... Figure 10 , 11 As shown, the double bucket body is compatible with both "belt loading" and "vehicle loading" functions. The opening degree of the flat gate and the extension parameters of the telescopic chute mechanism 6 can be switched through the operation control system. It can flexibly adapt to the scenarios of continuous material feeding by belt conveyor or batch loading by vehicle, expand the scope of application of the equipment, and has high applicability.

[0030] Specifically, in an embodiment of this utility model, the distributor 503 includes: a mounting base 8; an electro-hydraulic push rod 9 disposed on the mounting base 8; a connecting mechanism 10 disposed at the end of the electro-hydraulic push rod 9; and a distributor plate 11 disposed on the connecting mechanism 10.

[0031] like Figure 6 As shown in this embodiment of the utility model, the distributor 503 is composed of the mounting base 8, the electro-hydraulic push rod 9, the connecting mechanism 10, and the distributor plate 11. The electro-hydraulic push rod 9 is mounted on the mounting base 8, and the distributor plate 11 is mounted on the movable end of the electro-hydraulic push rod 9 through the connecting mechanism 10. When material needs to be divided, the electro-hydraulic push rod 9 pushes the distributor plate 11 to move and adjust the position of the distributor plate 11, so that the material can be divided into two equal parts and unloaded into the first hopper 501 and the second hopper 502.

[0032] Specifically, in an embodiment of this utility model, the telescopic chute mechanism 6 includes: a mounting housing 601 disposed at the bottom of the electro-hydraulic flat gate 504; a telescopic dustproof cover 602 connected to the mounting housing 601; a pipe interface 603 disposed on the side wall of the telescopic dustproof cover 602; one end of the suction pipe 305 connected to the pipe interface 603; a central chute 604 disposed inside the telescopic dustproof cover 602; a drive mechanism 605 disposed inside the mounting housing 601; a lifting mechanism 606 connecting the drive mechanism 605 and the telescopic dustproof cover 602; and a dustproof skirt 607 disposed at the bottom of the telescopic dustproof cover 602.

[0033] like Figure 7 , 8 As shown, in this embodiment of the present invention, the telescopic chute mechanism 6 is used to unload materials from the bucket onto a transmission belt or a dump vehicle. In this embodiment, the telescopic chute mechanism 6 consists of the mounting housing 601, a telescopic dustproof cover 602, a central chute 604, a drive mechanism 605, a lifting mechanism 606, and a dustproof skirt 607. The drive mechanism 605 provides power support, linking the lifting mechanism 606 to execute the lifting and lowering action (telescopic action) of the central chute 604. The central chute 604 is connected to the electro-hydraulic flat gate 504. It serves as the main channel for material descent; the telescopic dustproof cover 602 wraps around the outside of the central chute 604, forming a dust-sealed space; the dustproof skirt 607 is located at the bottom of the telescopic dustproof cover 602, making flexible contact with the material pile, and can prevent dust from overflowing during operation; when the material falls onto the material pile through the central chute 604, the height of the material pile gradually increases as the material accumulates, and the operation control system controls the height of the central chute 604 through the lifting mechanism 606 to keep it at a suitable distance from the material, preventing the material from impacting the material pile and causing dust to overflow.

[0034] Specifically, in an embodiment of this utility model, the telescopic dust cover 602 includes: a telescopic cover 12 vertically disposed on the mounting box 601; a first support component 13 connected to the telescopic cover 12; and a second support component 14 disposed at the bottom end of the telescopic cover 12.

[0035] Specifically, in the embodiments of this utility model, the first support component 13 is provided in multiple sets; the multiple sets of the first support components 13 are arranged parallel to each other on the telescopic cover 12, and the first support components 13 are spaced apart by a predetermined distance.

[0037] like Figure 7 , 8 As shown, in this embodiment of the present invention, the lifting mechanism 606 connects the first support component 13 and the second support component 14 and performs lifting and lowering operations on them, thereby executing the extension and retraction of the central chute 604. In this embodiment, the central chute 604 is a conical chute with a conical structure design. The opening at the upper end of the chute is larger than the opening at the lower end. The upper opening side of each central chute 604 is connected to the corresponding first support component 13. Multiple central chute 604s are connected end-to-end to form the main channel for material unloading. As shown in the figure, when the central chute 604 adopts... When using a conical structure design, as the material falls, the cross-section of the cone bottom of the central chute 604 gradually decreases, the fluid velocity increases, and a local negative pressure zone is formed at the rear of the cone bottom. This negative pressure zone generates a Venturi effect, drawing air from the connection between the upper and lower cones into the central chute 604. After mixing with the material flow, the material continues to fall, preventing dust from spreading out of the protective cover. In addition, in conjunction with the dust removal mechanism 3, the fine dust remaining in the telescopic dustproof cover 602 is drawn into the dust removal box 301 through the suction pipe 305, so that the dustproof cover is always kept in a slightly negative pressure state, which can completely block the dust overflow path.

[0038] Specifically, in an embodiment of this utility model, the lifting mechanism 606 includes: a first fixed pulley group 15 disposed within the mounting housing 601; a second fixed pulley group 17 disposed within the mounting housing 601 and arranged parallel to the first fixed pulley group 15; a first lifting wire rope 16 disposed on the drive mechanism 605; one end of the first lifting wire rope 16 is connected to the drive mechanism 605, and the other end successively passes upward around the first fixed pulley group 15, downward through the first support assembly 13, and is connected to the second support assembly 14; a second lifting wire rope 18 disposed on the drive mechanism 605; one end of the second lifting wire rope 18 is connected to the drive mechanism 605, and the other end passes upward around the second fixed pulley group 17, and downward to the first support assembly 13.

[0039] like Figure 7 , 8As shown, in this embodiment of the present invention, the lifting mechanism 606 is used to link the drive mechanism 605 to perform the extension and retraction action of the central chute 604; in this embodiment, the lifting mechanism 606 is composed of a first fixed pulley group 15, a second fixed pulley group 17, a first lifting wire rope 16, and a second lifting wire rope 18; wherein, the first fixed pulley group 15 and the first lifting wire rope 16 are combined to form a first lifting system, one end of the first lifting wire rope 16 in the first lifting system is connected to the drive mechanism 605, and the other end first passes around the first fixed pulley group 15, and then... The second lifting system consists of a second fixed pulley block 17 and a second lifting wire rope 18. The second lifting wire rope 18 passes through multiple first support components 13 in sequence and is finally connected to the second support component 14 via a fastening device. One end of the second lifting wire rope 18 in the second lifting system is connected to the drive mechanism 605, and the other end, after passing around the second fixed pulley block 17, is directly connected to the second support component 14 via a fastening device. When lifting operations are performed, the first lifting system and the second lifting system rise or fall synchronously, and work together to realize the extension and retraction of the central chute 604.

[0040] Specifically, in an embodiment of this utility model, the side wall of the mounting box 601 is provided with a pipe interface 603, and one end of the suction pipe 305 is connected to the pipe interface 603.

[0041] Specifically, in an embodiment of this utility model, the dust removal grid 4 includes: multiple L-shaped grid plates 401 arranged side by side; a rubber sheet 402 vertically arranged at the end of the L-shaped grid plate 401; the bottom end of the rubber sheet 402 abuts against the adjacent L-shaped grid plate 401.

[0042] like Figure 9 As shown in the embodiment of this utility model, the dust removal grid 4 is composed of multiple L-shaped grid plates 401 and multiple rubber sheets 402. The L-shaped grid plates 401 are arranged parallel to each other, and one end of the rubber sheet 402 is vertically installed at one end of the L-shaped grid plate 401, while the bottom end of the rubber sheet 402 abuts against the adjacent L-shaped grid plate 401. The L-shaped grid plates 401 are used to intercept large particles (such as ore blocks), while the rubber sheet 402 can suppress the overflow of dust particles larger than 5 mm.

[0043] As described above, the efficient and environmentally friendly bulk cargo hopper structure provided by this utility model aims to solve the problems of low loading and unloading efficiency and serious dust overflow during the loading and unloading process of traditional bulk cargo hopper structures. To address these problems, this utility model discloses an efficient and environmentally friendly bulk cargo hopper structure, which includes the main frame assembly 1, feeding channel 2, dust removal mechanism 3, dust removal grid 4, double hopper mechanism 5, and telescopic chute mechanism 6. By setting up the double hopper mechanism 5 and adopting a double hopper structure design, loading and unloading requirements are improved. Furthermore, combined with the dust removal mechanism 3, dust removal grid 4, and telescopic chute mechanism 6, a three-level dust control strategy of "negative pressure adsorption - grid interception - sealing inhibition" is formed, which can reduce the concentration of dust overflow and accurately meet environmental protection requirements. Specifically, the high-efficiency and environmentally friendly bulk cargo hopper structure disclosed in this utility model consists of a main frame assembly 1, a feeding channel 2, a dust removal mechanism 3, a dust removal grid 4, a double hopper mechanism 5, and a telescopic chute mechanism 6. The components are integrated through the main frame. The material to be loaded or unloaded is input from the feeding channel 2, passes through the dust removal grid 4, and falls into the double hopper mechanism 5. Finally, it is loaded or unloaded onto a vehicle or drive belt through the telescopic chute mechanism 6, forming an integrated system of high-efficiency operation and precise dust control, achieving a dual improvement in loading and unloading efficiency and environmental performance.For efficient operation, the bulk cargo hopper structure includes a double-hopper mechanism 5, which allows for parallel parking of two vehicles, significantly improving loading and unloading efficiency compared to the traditional single-hopper structure. For precise dust removal, the efficient and environmentally friendly bulk cargo hopper structure disclosed in this invention employs a three-stage dust control strategy: negative pressure adsorption, grid interception, and sealing suppression. The first stage utilizes the dust removal mechanism 3 to adsorb dust under negative pressure. In the dust removal mechanism 3, the negative pressure fan 302 is connected to the dust removal box 301. When the grab bucket unloads, the negative pressure fan 302 activates, creating a negative pressure field within the dust removal box 301, drawing dust escaping from the upper part of the hopper into the dust removal box 301. The dust removal box 301 is equipped with a filter cartridge assembly 303 for dust adsorption. The collected dust is then directionally sprayed by pulsed gas emitted from a pulse valve. The material falls directly into the hopper; secondly, the second-level strategy is to intercept dust through the dust removal grid 4. The material is input from the feed channel 2, then passes through the dust removal grid 4 into the double-hopper mechanism 5. The dust removal grid 4 can intercept large particles and prevent some dust particles from overflowing; finally, the third-level strategy for precise dust control is sealing and suppression. The material falls into the double-hopper mechanism 5 and then exits from the telescopic chute mechanism 6. The telescopic chute mechanism 6 can adjust the length of the chute according to the stacking height of the material pile to prevent the material from impacting the pile and causing dust to overflow. The telescopic chute mechanism 6 is connected to the dust removal mechanism 3 through the suction pipe 305. The suction pipe 305 is used to suck the dust in the telescopic chute mechanism 6 into the dust removal box 301 for negative pressure dust removal, further reducing dust overflow.
