Description

Technical Field

[0001] This utility model relates to the field of ship unloading machine technology, specifically to an environmentally friendly dust removal hopper for a bridge-type ship unloader. Background Technology

[0002] A bridge-type ship unloader is a continuous bulk cargo unloading device installed on a dockside rail system. It spans the ship's hold via a bridge structure and uses grab buckets, chain buckets, or suction hoppers to unload bulk cargo (such as coal, ore, and grain) from the hold onto the dock's conveyor system. However, traditional bridge-type ship unloaders have hoppers with small opening angles, making it easy for large pieces of material to get stuck in the opening. Precise control of the hopper opening angle is also difficult, making them unsuitable for different material sizes and prone to leakage. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-5 As shown, this utility model is an environmentally friendly dust removal hopper for a bridge-type ship unloader, including a fixed base 1 and a U-shaped frame 2. An opening and closing control mechanism 3 is provided between the fixed base 1 and the U-shaped frame 2. The opening and closing control mechanism 3 includes four connecting bars 31 rotatably connected to the fixed base 1, two hydraulic telescopic rods 32 fixedly connected to the top of the U-shaped frame 2, and four connecting arms 33 rotatably connected to the inner wall of the U-shaped frame 2. The hydraulic telescopic rods 32 can accurately control the extension and retraction accuracy to ensure clamping accuracy, and their output shafts have a locking function, which can lock the output shafts to maintain the stability of the hopper when closed. The hydraulic telescopic rods 32 are electrically connected to an external power source and are controlled by an external program. Half-hoppers 34 are fixedly connected between two adjacent connecting arms 33. A sleeve 35 is fixedly connected to the bottom of the left half-hopper 34, and a strip 36 is fixedly connected to the bottom of the right half-hopper 34. By setting an opening and closing control mechanism 3, the opening and closing angle of the hopper is precisely controlled by the hydraulic telescopic rod 32 to adapt to different material sizes. At the same time, the strip 36 is inserted into the matching sleeve 35 to achieve a tight sealing effect and prevent material leakage.

[0024] A dust extraction fan 4 is fixedly connected to the top of the U-shaped frame 2. The dust extraction fan 4 generates a strong negative pressure to draw dust generated during the unloading process from inside the hopper and the surrounding environment, preventing dust from spreading into the air. The drawn-in dust is separated and collected by the filtration system inside the hopper, while clean air is discharged, thus improving the air quality of the working environment. This is existing technology and will not be elaborated further in this article. The dust extraction fan 4 is electrically connected to an external power source and is controlled by an external program. A suction pipe 5 is connected to the bottom of the dust extraction fan 4. A quick-release anti-blocking mechanism 6 is installed between the U-shaped frame 2 and the suction pipe 5. This mechanism allows for quick disassembly and assembly of the anti-blocking mesh layer 64, reducing the operation time required for disassembly and facilitating its replacement.

[0025] The quick-release anti-clogging mechanism 6 includes two electric telescopic rods 61 fixedly connected to the inner wall of the U-shaped frame 2 and four positioning rods 62 slidably connected to the inner wall of the suction pipe 5. Each of the two electric telescopic rods 61 has a locking rod 63 fixedly connected to its output end. The electric telescopic rods 61 can precisely control their extension and retraction accuracy to ensure clamping precision, and their output shafts have a locking function to maintain the stability of the anti-clogging mesh layer 64. The electric telescopic rods 61 are electrically connected to an external power source and controlled by an external program. The anti-clogging mesh layer 64 is fixedly connected between the bottom ends of the four positioning rods 62, and the anti-clogging mesh layer 64 has mesh holes to prevent material blockage.

[0026] The four connecting bars 31 are rotatably connected to the adjacent connecting arms 33 respectively, and the output ends of the two hydraulic telescopic rods 32 are rotatably connected to the fixed base 1.

[0027] The insert 36 and the sleeve 35 are compatible with each other. The two half hoppers 34 have the same structure and are symmetrically distributed with the U-shaped frame 2 as the center.

[0028] Both buckle rods 63 are compatible with the anti-clogging mesh layer 64. The four positioning rods 62 are inserted into the suction pipe 5 to quickly and initially position the anti-clogging mesh layer 64. The suction pipe 5 and the U-shaped frame 2 are fixedly connected.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] The working principle of this utility model is as follows: First, the four positioning rods 62 are slidably inserted into the suction pipe 5 to quickly align and position the anti-clogging mesh layer 64 on the suction pipe 5. Then, the output shafts of the two electric telescopic rods 61 are extended, allowing the two electric telescopic rods 61 to drive the two locking rods 63 into the anti-clogging mesh layer 64 to quickly lock the anti-clogging mesh layer 64 (the disassembly operation can be quickly achieved by controlling the retraction of the output shafts of the two electric telescopic rods 61). After the fixing seat 1 is installed on the steel cable of the unloader, the two hydraulic telescopic rods 32 are activated to allow the two output shafts to retract. The retraction mechanism drives the U-shaped frame 2 to move upwards. When the U-shaped frame 2 moves, it drives the four connecting arms 33 to move through the four connecting bars 31. At the same time, it drives the two half-hoppers 34 to move through the four connecting arms 33, so that the two half-hoppers 34 close to grab the material. At the same time, the insert bar 36 is inserted into the insert sleeve 35 to close and prevent material leakage (by controlling the extension of the output shaft of the two hydraulic telescopic rods 32, the closed state can be quickly released and the material can be unloaded). At the same time as unloading, the dust suction fan 4 is started, so that it can suck up the dust through the suction pipe 5.
