Technical Field
[0001] This utility model relates to the field of dust removal technology for mine bin unloading, specifically to a mobile mine bin dust removal and unloading vehicle. Background Technology
[0002] In the metallurgical industry, ore bins are mainly used to store and transfer ore raw materials. Generally, a belt conveyor is used in conjunction with a mobile electrically controlled unloading vehicle to load materials into each bin. The mobile electrically controlled unloading vehicle can move along the conveying direction on the belt conveyor. The ore raw materials conveyed on the belt conveyor can be loaded into multiple bins through the mobile electrically controlled unloading vehicle. During loading, due to the large drop of the material and the positive pressure inside the bin, a large amount of dust-containing gas escapes from the bin inlet after the ore raw materials fall into the bin, seriously polluting the environment around the bin and endangering the health of the operators. Utility Model Content
[0003] This invention addresses the technical problem of large amounts of dust generated when unloading materials from a hopper, which seriously pollutes the surrounding environment. It provides a mobile ore bin dust removal unloading vehicle that can remove dust while loading materials, effectively avoiding the impact of large amounts of dust on the surrounding environment. Furthermore, this design is simple in structure, low in cost, stable in movement, and easy to use.
[0004] The technical solution adopted by this utility model is as follows: 1. A mobile ore bin dust removal and unloading vehicle, including a mobile frame, a slide rail, and a first track wheel rotatably disposed at the lower end of the mobile frame. The first track wheel is adapted to the slide rail. It also includes a conveyor frame disposed on the mobile frame, a roller assembly rotatably disposed on the conveyor frame, a distributor disposed on the mobile frame and located below the output end of the conveyor frame, a dust collector disposed on the conveyor frame, a dust guide cover disposed on the mobile frame and covering the output end of the conveyor frame and the distributor, and an air guide pipe disposed between the air inlet end of the dust collector and the dust guide cover.

Detailed Implementation
[0018] like Figure 1-5 As shown, this utility model provides a mobile ore bin dust removal and unloading vehicle, including a mobile frame 1, a slide rail 2, a first track wheel 3 rotatably mounted at the lower end of the mobile frame 1, the first track wheel 3 being adapted to the slide rail 2, a conveyor frame 4 mounted on the mobile frame 1, a roller assembly rotatably mounted on the conveyor frame 4, a distributor 5 mounted on the mobile frame 1 and located below the output end of the conveyor frame 4, a dust collector 6 mounted on the conveyor frame 4, a dust guide cover 7 mounted on the mobile frame 1 and covering the output end of the conveyor frame 4 and the distributor 5, and an air guide pipe 8 mounted between the air inlet end of the dust collector 6 and the dust guide cover 7. The mobile frame 1 has the freedom to move on the slide rail 2 by means of the first track wheel 3, and the air inlet end of the dust collector 6 is connected to the dust guide cover 7 by means of the air guide pipe 8.
[0019] This design is used in conjunction with a belt conveyor. Two slide rails 2 can be installed on the belt conveyor frame, located on both sides of the conveyor belt, or additional mounting brackets can be added to both sides of the belt conveyor frame to install the slide rails 2. The conveyor belt passes over the roller assembly on the conveyor frame 4. The ore on the belt conveyor can move onto the conveyor frame 4 under the drive of the conveyor belt. The ore falls at the output end of the conveyor frame 4 and into the feed inlet at the upper end of the distributor 5. A large amount of dust is generated when the ore falls; therefore, a dust guide hood 7 is added at this location. The dust guide hood 7 is a box-type structure with openings on one side and the bottom. The openings are located facing the direction of the dust guide hood 7. On one side of the conveyor frame 7, the conveyor belt is not obstructed from conveying ore, and a dust curtain is installed at the opening. The opening at the lower end of the dust guide hood 7 is fixed to the upper feed port of the distributor 5. The output end of the conveyor frame 7 extends into the dust guide hood 7 through the opening on one side. The ore falls into the distributor 5 inside the dust guide hood 7, which can limit the generated dust inside the dust guide hood 7. The dust collector 6 extracts the dust inside the dust guide hood 7 through the air duct 8. After the dust enters the dust collector 6, it is removed, which effectively avoids the pollution of the surrounding environment by dust and eliminates the impact on the health of the workers. Moreover, this design is simple and effective, low in cost, stable in movement, and easy to use.
[0020] like Figure 1 and 3 As shown, it also includes a drive motor 9 mounted on the movable frame 1 and connected to the first track wheel 3 for transmission. The first track wheel 3 and the drive motor 9 are provided in two sets and are spaced apart along the moving direction of the movable frame 1.
[0021] The drive motor 9 can drive the first track wheel 3 to rotate, thereby moving the mobile frame 1 on the slide rail 2. The operation is simple and the control is convenient. Furthermore, the two sets of first track wheels 3 and drive motor 9 can further improve the stability of the unloading vehicle.
[0022] like Figure 1-2 As shown, the roller assembly includes a support roller 10 disposed on the upper end of the conveyor frame 4, a first guide roller 11 disposed on the output end of the conveyor frame 4 and located inside the dust guide cover 7, and a second guide roller 12 disposed on the movable frame 1 and located below the output end of the conveyor frame 4. Multiple sets of support rollers 10 are equidistantly arranged on the upper end of the conveyor frame 4 along the conveying direction. The support rollers 10, the first guide roller 11 and the second guide roller 12 are all rotatably disposed.
[0023] The conveyor belt of the belt conveyor is first laid from the outer end of the conveyor frame 4 onto multiple sets of idlers 10 on the conveyor frame 4 along the feeding direction. After passing the idlers 10, it is wrapped around the first guide roller 11, and then wrapped downwards to the second guide roller 12, and finally returns to the belt conveyor. The horizontal position of the second guide roller 12 is below the front end of the first guide roller 11. After passing the first guide roller 11, the conveyor belt folds back in the input direction so that the ore falling onto the distributor 5 will not collide with the conveyor belt.
[0024] like Figure 1-2 As shown, the conveyor frame 4 includes an output frame 13 mounted on the movable frame 1, an input frame 14 mounted on the movable frame 1 and corresponding to the input end of the output frame 13, and a second track wheel 15 rotatably mounted at the lower end of the input frame 14. The second track wheel 15 is horizontally corresponding to the first track wheel 3. One end of the input frame 14 corresponding to the output frame 13 is hinged to the movable frame 1, and the other end extends horizontally forward along the moving direction of the movable frame 1. The output end of the output frame 13 is located inside the dust guide cover 7.
[0025] The conveyor frame 4 is a split design, consisting of an output frame 13 and an input frame 14. The output frame 13 is fixedly installed, while the input frame 14 is hinged and supported at its lower end by the second track wheel 15. During the installation of the unloading vehicle, if the installation accuracy is not up to standard, the first track wheel 3 in the middle and the slide rail 2 are prone to gaps or even separation, causing unstable movement and power failure. After the moving frame 1 is installed on the slide rail 2, the hinged connection of the input frame 14 can swing adaptively according to the force conditions, ensuring that the two sets of first track wheels 3 and slide rail 2 are effectively engaged, improving the running stability of the unloading vehicle and reducing the installation accuracy requirements.
[0026] like Figure 3-4 As shown, the feeder 5 includes a housing 16, a feed inlet 17 located at the upper end of the housing 16, a middle discharge outlet 18 located at the lower end of the housing 16, and side discharge outlets 19 located at the lower end of the housing 16 and respectively located on both sides of the middle discharge outlet 18, and a discharge pipe 20 located on the side discharge outlets 19. The upper end of the discharge pipe 20 is connected to the side discharge outlet 19, and the lower end is vertically downward.
[0027] The distributor 5 adopts a four-way structure, with a feed inlet 17 at the top and three outlets at the bottom: a central outlet 18 and two side outlets 19. The distributor 5 uses a slide valve to control which outlet the ore exits from. The central outlet 18 is used in conjunction with other belt conveyors, allowing the ore to fall onto these conveyors and thus transfer the ore. The two side outlets 19 correspond to the feed inlets of the two rows of silos, allowing the ore to fall into the silos through the discharge pipe 20. The structure of the distributor 5 is existing technology and was purchased from the market; its principle will not be explained in detail here.
[0028] like Figure 1 and 3 As shown, it also includes a first guide roller 21 disposed on both sides of the lower opening of the feeding pipe 20, a second guide roller 22 disposed on the movable frame 1 and located on both sides of the side discharge port 19 and respectively above the first guide roller 21, a covering strip 23 sequentially surrounding the first guide roller 21 and the second guide roller 22 on the same side, the second guide roller 22 and the first guide roller 21 on the other side, and mounting frames 24 corresponding to the positions of the two ends of the slide rail 2. The first guide roller 21 and the second guide roller 22 are both rotatable. The covering strip 23 is arranged parallel to the moving trajectory of the movable frame 1, and the two ends of the covering strip 23 are respectively mounted on the mounting frames 24.
[0029] During loading, the feed inlet of the silo is generally kept open. To prevent dust remaining in the silo from spraying out after the ore is loaded, a covering belt 23 is added. The length of the covering belt 23 is the same as that of the slide rail 2. Both ends of the covering belt 23 are fixed by the mounting bracket 24. The position of the mounting bracket 24 corresponds to the position of both ends of the slide rail 2. Guided by the first guide roller 21 and the second guide roller 22, the covering belt 23 avoids the silo corresponding to the side discharge port 19, does not hinder unloading, and covers the feed inlet of the other silos, effectively preventing dust from escaping from the silos that have been loaded with ore, and further reducing the impact of dust on the surrounding environment.
[0030] like Figure 5 As shown, it also includes an intermediate air extraction pipe 25 and two side air extraction pipes 26 disposed between the dust collector 6 and the distributor 5. The output ends of the intermediate air extraction pipe 25 and the two side air extraction pipes 26 are connected to the air inlet end of the dust collector 6. The input end of the intermediate air extraction pipe 25 is arranged side by side with the intermediate discharge port 18, and the two side air extraction pipes 26 are arranged side by side with the discharge pipes 20 at the lower end of the two side discharge ports 19, respectively.
[0031] On one side of the discharge port of the distributor 5, there is a parallel exhaust pipe, including a central exhaust pipe 25 and two side exhaust pipes 26. When the ore falls from the central discharge port 18, the dust collector 6 sucks dust from the central discharge port 18 at the lower end of the distributor 5 through the central exhaust pipe 25. A cover is designed on the output end of the side exhaust pipes 26 and the discharge pipe 20. The cover is a box-shaped structure with an open bottom. The lower ends of the side exhaust pipes 26 and the discharge pipe 20 are inserted from the upper end of the cover and communicate with the inner cavity of the cover. The size of the cover is larger than the feed inlet of the hopper and can cover the feed inlet of the hopper to reduce the leakage of dust from the hopper. At the same time, the dust collector 6 can suck dust from the hopper through the side exhaust pipes 26, which can not only further improve the dust removal effect, but also balance the air pressure in the hopper.
