Description

Technical Field

[0001] This application relates to the field of stacking equipment technology, and in particular to a mobile telescopic stacker. Background Technology

[0002] With the continuous development of the social economy and the increasing level of science and technology, my country's industry is also booming. As a high-efficiency equipment for continuous stacking of bulk materials, stackers are widely used in metallurgy, ports, mines and other places for stacking materials such as coal, coke, ore and salt.

[0003] A mobile telescopic stacker exists in the prior art, comprising a body, on which a connecting truss and a telescopic truss are mounted. The connecting truss is connected to the body and sleeved over the telescopic truss. The telescopic truss and the connecting truss are slidably connected. The body is equipped with a drive mechanism for driving the telescopic truss to slide. Conveyor belts are mounted on both the connecting truss and the telescopic truss, with the conveyor belt on the connecting truss positioned at its top and above the telescopic truss. In use, material is poured onto the bottom end of the conveyor belt on the connecting truss, and the conveyor belt carries the material upwards. Upon reaching the top of the conveyor belt, the material falls downwards under its own weight onto the conveyor belt on the telescopic truss, and then falls to the ground via the top of the conveyor belt.

[0004] Regarding the aforementioned technologies, in actual use, the telescopic stacker raises the end of the telescopic truss away from the connecting truss to a certain height. This causes a large amount of dust to be stirred up when materials fall from the telescopic truss, resulting in environmental pollution and potentially harming the health of workers. Summary of the Invention

[0005] To reduce dust falling from the telescopic truss, this application provides a mobile telescopic stacker.

[0006] This application provides a mobile telescopic stacker, which adopts the following technical solution:

[0007] A mobile telescopic stacker includes a body, a connecting truss, and a telescopic truss. A conveyor belt is installed on the telescopic truss. A dust removal mechanism is also installed at the end of the telescopic truss away from the connecting truss. The dust removal mechanism includes a discharge hood, a dust suction pipe, a dust suction fan, and a storage box. The end of the conveyor belt away from the connecting truss is located directly above the discharge hood. One end of the dust suction fan is connected to a chamber inside the discharge hood through a dust suction pipe, and the other end of the dust suction fan is connected to a chamber inside the storage box through a pipe.

[0008] By adopting the above technical solution and configuring the dust removal mechanism, the material can fall through the discharge pipe under the transport of the conveyor belt on the telescopic truss. During this process, the dust suction fan can absorb the dust in the material passing through the discharge hood and introduce it into the collection box through the pipe, thereby reducing the amount of dust that falls from the telescopic truss and is raised, thus reducing the degree of environmental pollution and the degree of harm of the raised dust to the health of the staff, and effectively ensuring the health of the staff.

[0009] Preferably, the storage box is further provided with a dust collection box with an open top inside the cavity. The dust collection box is slidably connected to the inner wall of the storage box, and the sliding path of the dust collection box extends to the outside of the storage box. The storage box is also provided with a locking component for locking the dust collection box.

[0010] By adopting the above technical solution, the dust collection box is designed so that the dust sucked in by the vacuum fan and passed into the collection box will fall into the chamber of the dust collection box, thereby collecting the dust in the collection box. This allows relevant personnel to clean the dust in the collection box by sliding the dust collection box out of the collection chamber, thus facilitating the cleaning of dust.

[0011] Preferably, the storage box has an opening on one side, the sliding path of the dust collection box is in the same direction as the opening of the storage box, the opening of the storage box is provided with a switch door, one end of the switch door is rotatably connected to the storage box, and the storage box is also provided with a rotating mechanism for driving the switch door to rotate.

[0012] By adopting the above technical solution and setting the opening and closing door, the chance of the dust collection box sliding out of the storage box can be effectively reduced. At the same time, the existence of the opening and closing door can also seal the dust floating in the storage box, thereby reducing the chance of dust leakage from the storage box and thus effectively ensuring the dust collection effect.

[0013] Preferably, the rotating mechanism includes a drive frame and a linkage component. The drive frame is located on the side of the storage box away from the opening and closing door and on the sliding path of the dust collection box. The drive frame is rotatably connected to the storage box, and the drive frame drives the opening and closing door to rotate through the linkage component.

[0014] By adopting the above technical solution and configuring the drive frame, when the dust collection box slides into the storage chamber, one end of the dust collection box can abut against one end of the drive frame, thereby pushing the drive frame to rotate. The drive frame then uses a linkage component to gradually close the door. As personnel slide the dust collection box into the storage chamber, the door gradually closes simultaneously, which facilitates operation and saves manpower.

[0015] Preferably, the linkage component includes a driven gear, a driving rack, and a linkage member. The driven gear is connected to the opening and closing door rotation point, the driving rack is slidably connected to the storage box, the driving rack meshes with the driven gear, and the drive frame drives the driving rack to slide through the linkage member.

[0016] By adopting the above technical solution and configuring the drive mechanism of the linkage components, when the drive frame rotates, the drive frame can cause the active rack to slide through the linkage, thereby driving the driven gear to rotate. This causes the driven gear to drive the door to rotate as well, thus driving the door to open and close. At the same time, the configuration of the active rack and driven gear allows a small rotation of the drive frame to drive a large rotation of the door to open and close through the active rack and driven gear, thereby ensuring the closing effect of the door.

[0017] Preferably, the linkage includes a sliding block and a connecting frame. The sliding block is sleeved on the end of the drive frame away from the dust collection box. The sliding block and the connecting frame are rotatably connected. The connecting frame is slidably connected to the storage box and has the same sliding direction as the active rack. The connecting frame is connected to the active rack.

[0018] By adopting the above technical solution and specifically setting the linkage components, the rotation of the drive frame can drive the sliding block to rotate together, and the sliding block can slide along the length direction of the drive frame, so that the connecting frame can always be located on its own sliding trajectory, thereby realizing the drive of the active rack and ensuring that the rotation of the drive frame and the door opening and closing are continuous.

[0019] Preferably, the locking assembly includes a locking frame and an elastic element. The locking frame is slidably connected to the storage box, one end of the locking frame is inserted into the outer wall of the dust collection box, and the elastic element is used to allow the locking frame to be continuously inserted into the dust collection box.

[0020] By adopting the above technical solution and specifically setting the locking component, when the dust collection box slides to the designated position inside the storage box, the locking frame can be inserted into the dust collection box to lock the dust collection box. At the same time, the presence of the elastic element can also ensure that the locking frame is continuously inserted into the dust collection box, thereby ensuring the locking effect on the dust collection box.

[0021] Preferably, the drive frame is also provided with a limiting component, which includes a rotating frame and a limiting frame. One end of the rotating frame is rotatably connected to the end of the drive frame near the dust collection box, and the other end of the rotating frame is rotatably connected to the limiting frame. The limiting frame is slidably connected to the storage box, and the sliding direction of the limiting frame is the same as that of the locking frame, and it abuts against the locking frame.

[0022] By adopting the above technical solution and configuring the limiting component, when the door gradually closes, the rotation of the drive frame causes the active frame to shift, thereby causing the limiting frame to gradually slide away from the locking frame. During this process, under the action of the elastic element, the limiting frame always abuts against the locking frame, allowing the limiting frame to gradually contact and restrict the locking frame, thus allowing the locking frame to gradually insert into the dust collection box. At the same time, when the door is open, the limiting frame and the locking frame abut against each other, keeping the locking frame detached from the dust collection box. This replaces the manual steps of manually pulling out the locking frame and manually maintaining the locking frame detached from the dust collection box when sliding out and in, thus facilitating the operation of relevant personnel and saving manpower.

[0023] Preferably, the storage box is also provided with a locking assembly, which includes a locking frame and a spring element. The locking frame is slidably connected to the storage box and inserted into the closed switch door. The spring element is used to allow the locking frame to be continuously inserted into the switch door.

[0024] By adopting the above technical solution and setting the locking component, when the door is in the closed state, the locking bracket can be inserted into the door to lock it. At the same time, the presence of the spring element can also ensure that the locking bracket is continuously inserted into the door, thereby ensuring the locking effect of the door.

[0025] Preferably, the telescopic truss is also equipped with a dust suppression mechanism, which includes a water storage tank, a dust suppression pump and a dust suppression nozzle. The water storage tank is installed on the telescopic truss, and the water storage tank is connected to the dust suppression pump through a pipe. The dust suppression pump is connected to the dust suppression nozzle through a pipe, and one end of the dust suppression nozzle extends into the discharge hood and is located below the suction pipe.

[0026] By adopting the above technical solution and configuring the dust suppression mechanism, the dust suppression pump can draw water from the water storage tank and introduce it into the dust suppression nozzle. This allows the dust suppression nozzle to spray water onto the material in the discharge hood, thereby suppressing dust in the material. This reduces the amount of dust that falls from the telescopic truss and is raised, thus reducing environmental pollution and minimizing the harm of the raised dust to the health of workers, effectively ensuring their health.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The dust removal mechanism is designed so that when materials are transported by the conveyor belt on the telescopic truss, they can fall through the discharge pipe under the transport of the conveyor belt. During this process, the dust suction fan can absorb the dust in the materials passing through the discharge hood and put it into the collection box through the pipe. This reduces the amount of dust that falls from the telescopic truss and is raised, thereby reducing the degree of environmental pollution and the degree of harm of the raised dust to the health of the staff, effectively ensuring the health of the staff.

[0029] 2. The design of the dust collection box, the opening and closing door, and the rotating mechanism allows relevant personnel to collect dust through the dust collection box and seal the dust in the collection chamber through the opening and closing door. At the same time, the presence of the rotating mechanism also ensures that the opening and closing door gradually closes as the relevant personnel slide the dust collection box into the collection box, thereby facilitating the operation of relevant personnel and saving manpower.

[0030] 3. The dust suppression mechanism is designed so that the dust pump can draw water from the water storage tank and supply it to the dust suppression nozzles. The nozzles can then spray water onto the material in the discharge hood, thereby suppressing dust in the material. This reduces the amount of dust that falls from the telescopic truss and is raised, thus reducing environmental pollution and minimizing the harm of raised dust to the health of workers, effectively protecting their health.

[0038] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0039] This application discloses a mobile telescopic stacker. (Refer to...) Figure 1 and Figure 2 The mobile telescopic stacker includes a body 1, a connecting truss 2, and a telescopic truss 3. A moving belt 21 is installed on the connecting truss 2, and a conveyor belt 31 is installed on the telescopic truss 3. A dust removal mechanism 4 is also installed on the end of the telescopic truss 3 away from the connecting truss 2. The dust removal mechanism 4 includes a discharge hood 41, a dust suction pipe 42, a dust suction fan 43, and a storage box 44. The end of the conveyor belt 31 away from the connecting truss 2 is located directly above the discharge hood 41. One end of the dust suction fan 43 is connected to the chamber inside the discharge hood 41 through the dust suction pipe 42, and the other end of the dust suction fan 43 is connected to the chamber inside the storage box 44 through a pipe.

[0040] Reference Figure 1 and Figure 2 The top of the discharge hood 41 is fixedly connected to the telescopic truss 3 by bolts. The end of the conveyor belt 31 is located at one end directly above the discharge hood 41. The discharge hood 41 is a tubular hood. An installation ring 45 is also fitted on the outside of the discharge hood 41. The installation ring 45 is fixedly connected to the discharge hood 41 by bolts, and a cavity is opened inside the installation ring 45. Multiple suction pipes 42 are arranged circumferentially along the axis of the installation ring 45. One end of each suction pipe 42 communicates with the internal cavity of the installation ring 45, and the other end extends to the inside of the discharge hood 41.

[0041] Reference Figure 1 and Figure 2The mounting ring 45 is connected to one end of the vacuum cleaner 43 via a pipe, and the vacuum cleaner 43 is fixedly connected to the side wall of the storage box 44 by bolts and brackets. The other end of the vacuum cleaner 43 is connected to the chamber inside the storage box 44 via a pipe, and the top of the storage box 44 is fixedly connected to the telescopic truss 3 by bolts.

[0042] Reference Figure 2 , Figure 3 and Figure 4 An opening is provided on the side wall of the storage box 44 away from the vacuum cleaner fan 43, and the opening communicates with the cavity inside the storage box 44. A dust collection box 5 with an opening at the top is also provided inside the cavity of the storage box 44. The dust collection box 5 is slidably connected to the inner wall of the storage box 44 via a slide rail. The sliding direction of the dust collection box 5 is the opening direction of the opening, and the sliding path of the dust collection box 5 extends to the outside of the storage box 44. A pull-out handle 51 is also provided at the bottom of the dust collection box 5, and the pull-out handle 51 is fixedly connected to the dust collection box 5 by bolts.

[0043] Reference Figure 3 , Figure 4 and Figure 5 The storage box 44 is also equipped with a locking assembly 6, which includes a sliding frame 61, a locking frame 62, and an elastic element 63. The sliding frame 61 is located inside the storage box 44 and is slidably connected to the storage box 44. The sliding direction of the sliding frame 61 is perpendicular to the sliding direction of the dust collection box 5. There are two locking frames 62, which are distributed along the width direction of the dust collection box 5, and the bottom end of each locking frame 62 is fixedly connected to the connecting frame 8232 by welding. Each locking frame 62 is located on the sliding path of the dust collection box 5, and the top of each locking frame 62 near the opening of the storage box 44 has an arc-shaped guide surface.

[0044] Reference Figure 3 , Figure 4 and Figure 5 Each locking frame 62 is provided with an elastic element 63. Optionally, the elastic element 63 is a compression spring. The elastic element 63 is sleeved on the corresponding locking frame 62, and the top end of the elastic element 63 abuts against the locking frame 62, and the bottom end of the elastic element 63 abuts against the inner wall of the storage box 44, so that the elastic element 63, through its own elastic force, keeps the locking frame 62 continuously inserted at the bottom of the dust collection box 5 for locking.

[0045] Reference Figure 3The storage box 44 is equipped with a switch door 441 at its opening. The top of the switch door 441 is rotatably connected to the storage box 44 via a pin. A ventilation groove 4411 is formed through the top of the side wall of the switch door 441, and the ventilation groove 4411 communicates with the chamber inside the storage box 44. A filter screen 46 is also installed inside the ventilation groove 4411. The filter screen 46 is fixedly connected to the inner wall of the ventilation groove 4411 by bolts to prevent dust from entering the storage box 44, thus keeping the dust inside the storage box 44.

[0046] Reference Figure 3 and Figure 4 The bottom side wall of the switch door 441 is also provided with a clearance groove 4412 to allow the pull handle 51 on the dust collection box 5 to pass through. The bottom of the switch door 441 is also provided with two locking grooves 4413, which are located at both ends of the switch door 441 along its own length.

[0047] Reference Figure 3 , Figure 4 and Figure 5 A locking component 7 is also provided at the bottom of the opening of the storage box 44. Optionally, two locking components 7 are provided, distributed along the width of the storage box 44, and corresponding one-to-one with the locking grooves 4413. Each locking component 7 includes a locking frame 71 and a spring element 72. The bottom end of each locking frame 71 is fixedly connected to the sliding frame 61 by welding and is slidably connected to the inner wall of the storage box 44.

[0048] Reference Figure 3 , Figure 4 and Figure 5 Each locking bracket 71 is located on the displacement path of the opening and closing door 441, and an arc-shaped guide surface is provided on the side of the top of each locking bracket 71 away from the locking bracket 62. Optionally, the elastic element 72 is a pressure spring, and each elastic element 72 is sleeved on the corresponding locking bracket 71. The bottom end of each elastic element 72 abuts against the locking bracket 71 and the inner wall of the storage box 44.

[0049] Reference Figure 3 , Figure 4 and Figure 5 Initially, the switch door 441 is in the open state. When the switch door 441 is rotated downwards, closing the switch door 441, the bottom end of the switch door 441 gradually approaches the locking bracket 71, and the bottom end of the switch door 441 abuts against the arc-shaped guide surface on the locking bracket 71, causing the locking bracket 71 to slide downwards and avoid the switch door 441. When the locking bracket 71 corresponds to the locking groove 4413 on the switch door 441, the locking bracket 71 is inserted into the locking groove 4413 under the elastic force of the elastic member 72, thus locking the switch door 441.

[0050] Reference Figure 3 , Figure 4 and Figure 5 The sliding frame 61 is also equipped with a switch handle 611. One end of the switch handle 611 extends into the storage box 44 and is fixedly connected to the sliding frame 61 by bolts. The switch handle 611 is also slidably connected to the storage box 44. When it is necessary to unlock the door 441 and the dust collection box 5, the switch handle 611 is pulled out. At this time, the switch handle 611 drives the locking frame 71 and the locking frame 62 to slide through the sliding frame 61, causing the locking frame 71 to slide out of the locking groove 4413 and the locking frame 62 to slide out of the dust collection box 5, thereby unlocking the door 441 and the dust collection box 5. Afterwards, the relevant personnel pull the handle 51 to slide the dust collection box 5 and push the door 441 to open.

[0051] Reference Figure 3 , Figure 4 and Figure 6 The storage box 44 is also equipped with a rotating mechanism 8, which includes a drive frame 81 and a linkage component 82. The upper middle part of the drive frame 81 is rotatably connected to the storage box 44 via a bearing. The drive frame 81 is located on the side of the dust collection box 5 away from the switch door 441. The drive frame 81 is located on the sliding path of the dust collection box 5, and the bottom end of the drive frame 81 is offset towards the dust collection box 5 so that the dust collection box 5 first contacts the bottom end of the drive frame 81, thereby driving the bottom end of the drive frame 81 to rotate away from the drive frame 81.

[0052] Reference Figure 3 , Figure 4 and Figure 6 Optionally, the number of linkage components 82 is set to two, and they are located on both sides of the drive frame 81 along the width direction of the storage box 44. Each linkage component 82 includes a driven gear 821, a driving rack 822, and a linkage member 823. The linkage member 823 includes a sliding block 8231 and a connecting frame 8232. An extension frame 811 is also provided at the top of the drive frame 81. The extension frame 811 is integrally formed with the drive frame 81 and extends along the height direction of the drive frame 81.

[0053] Reference Figure 3 , Figure 4 and Figure 6 Each sliding block 8231 corresponds one-to-one with an extension frame 811. Each sliding block 8231 is fitted onto its corresponding extension frame 811 and is slidably connected to it. Each sliding block 8231 is rotatably connected to one end of a connecting frame 8232 via a bearing. Each connecting frame 8232 is slidably connected to the storage box 44. The sliding direction of the connecting frame 8232 is always along the length of the storage box 44.

[0054] Reference Figure 3 and Figure 4Each connecting bracket 8232, at its end furthest from the sliding block 8231, is fixedly connected to one end of the corresponding active rack 822. The active rack 822 is slidably connected to the storage box 44 and its sliding direction is consistent with that of the connecting bracket 8232. Two driven gears 821 are located on both sides of the opening and closing door 441 along the width direction of the storage box 44, and are fixedly connected to the opening and closing door 441 by welding. Each driven gear 821 is located below the corresponding active rack 822 and meshes with the corresponding active rack 822.

[0055] Reference Figure 3 , Figure 4 and Figure 6 In the initial state, that is, when the switch door 441 is in the open state, the bottom end of the drive frame 81 is located on the side of its own rotation axis close to the switch door 441. When the relevant personnel slide the dust collection box 5 into the chamber inside the storage box 44, the dust collection box 5 gradually approaches the drive frame 81 and finally abuts against the bottom end of the drive frame 81, pushing the drive frame 81 to rotate.

[0056] Reference Figure 4 and Figure 6 At this time, the rotation of the drive frame 81 causes the sliding block 8231 to slide relative to the extension frame 811, and the sliding direction is upward along the extension direction of the extension frame 811. This causes the sliding block 8231 to drive the connecting frame 8232 to slide closer to the switch door 441, thereby causing the drive rack 822 to slide. During this process, the drive rack 822 continuously drives the driven gear 821 meshing with itself to rotate, thereby driving the switch door 441 to rotate downward. When the dust collection box 5 slides to the bottom of its sliding path, the drive frame 81 is in a vertical state, and at this time the switch door 441 is closed.

[0057] Reference Figure 3 , Figure 4 and Figure 6 The drive frame 81 is also equipped with a limiting component 83, which includes a rotating frame 831 and a limiting frame 832. Optionally, the number of rotating frames 831 can be set to several. One end of each rotating frame 831 is rotatably connected to the bottom end of the drive frame 81 on the side away from the dust collection box 5 via a pin, and the other end of each rotating frame 831 is rotatably connected to the limiting frame 832 via a pin. The rotatable connection between the limiting frame 832 and the rotating frame 831 is higher than the rotatable connection between the rotating frame 831 and the drive frame 81. The limiting frames 832 are all slidably connected to the inner wall of the storage box 44, and the sliding direction of the limiting frame 832 is the same as the sliding direction of the sliding frame 61.

[0058] Reference Figure 3 and Figure 6The storage box 44 is also equipped with several guide rods 833. Both ends of each guide rod 833 are fixedly connected to the inner wall of the storage box 44, and each guide rod 833 extends along the sliding direction of the limiting frame 832. One end of each guide rod 833 passes through the limiting frame 832 and is slidably connected to the limiting frame 832. The bottom end of the limiting frame 832 abuts against the top end of the sliding frame 61.

[0059] Reference Figure 3 and Figure 6 Each guide rod 833 is fitted with a return spring 834, and each return spring 834 is located above the limiting frame 832. The top end of each return spring 834 abuts against the inner wall of the storage box 44, and the bottom end of each return spring 834 abuts against the top end of the limiting frame 832.

[0060] Reference Figure 3 , Figure 4 and Figure 6 In the initial state, that is, when the door 441 is open, the bottom of the drive frame 81 is close to the door 441. At this time, the limit frame 832 is located at the lower part of its own sliding path. At this time, the sliding frame 61 is abutted by the bottom of the limit frame 832, so it is located at the bottom of its own sliding path. At this time, the locking frame 71 and the locking frame 62 both slide into the storage cavity.

[0061] Reference Figure 3 , Figure 4 and Figure 6 When the drive frame 81 rotates under the drive of the dust collection box 5, the drive frame 81 drives the rotating frame 831 to move, and the rotating frame 831 drives the limiting frame 832 to slide upward. At this time, the reset spring 834 is compressed, and the limiting frame 832 releases the current state of the restriction on the sliding frame 61, so that the sliding frame 61 can slide upward under the elastic force of the elastic member 63 and the elastic member 72.

[0062] Reference Figure 1 and Figure 2 The telescopic truss 3 is also equipped with a dust suppression mechanism 9, which includes a water storage tank 91, a dust suppression pump 92, a sleeve ring 93, and dust suppression nozzles 94. The sleeve ring 93 is fixedly sleeved on the discharge hood 41 and located below the mounting ring 45. A chamber is formed inside the sleeve ring 93, and multiple dust suppression nozzles 94 are arranged circumferentially along the axis of the sleeve ring 93. One end of each dust suppression nozzle 94 communicates with the chamber inside the sleeve ring 93 and is fixedly connected to the sleeve ring 93, while the other end of each dust suppression nozzle 94 extends to the inside of the discharge hood 41.

[0063] Reference Figure 1 and Figure 2One end of the dust pump 92 is connected to the sleeve ring 93 via a pipe, and the other end of the dust pump 92 is connected to the chamber inside the water storage tank 91 via a pipe. The water storage tank 91 is fixedly installed on the telescopic truss 3 by bolts, and the chamber of the water storage tank 91 stores liquid water.

[0064] The implementation principle of a mobile telescopic stacker according to an embodiment of this application is as follows: During use, the material is transported via the conveyor belt 31 on the telescopic truss 3 to directly above the discharge hood 41, falls into the interior of the discharge hood 41, and exits through the bottom end of the discharge hood 41 onto the ground. During this process, the dust extraction fan 43 uses the dust extraction pipe 42 to absorb the dust passing through the discharge hood 41 and directs it into the collection box 44 for storage. Simultaneously, the dust suppression pump 92 draws water from the water storage tank 91 and directs it into the sleeve ring 93, which is then sprayed out through the dust suppression nozzle 94 to suppress dust.

[0065] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
