Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of dust removal, and in particular relates to a dust removal device for a discharge port of a loader. Background Art
[0002] During the unloading process of the loader, the unloading port is the main source of dust generation, and a large amount of dust will fly from it, causing serious dust pollution. In order to solve this problem, it is usually necessary to fix a dust removal device at the unloading port to effectively collect and remove the generated dust.
[0003] However, traditional dust removal devices have many design deficiencies:
[0004] First, traditional dust removal devices cannot be effectively retracted and stored when not in use, resulting in crowded space in the loading and unloading room of the truck;
[0005] Second, the new generation of loaders adopts a retractable discharge port design, that is, when in use, it is flipped down to the upper position of the corresponding car body, and when no longer unloading, it is flipped up and retracted. However, the above-mentioned lowering and retracting actions often cannot achieve better coordination with traditional dust removal devices;
[0006] Third, during the loading process, in order to make the loading more uniform, the discharge port needs to swing slightly, and the traditional dust removal device often cannot achieve better cooperation at this time;
[0007] Fourth, when replacing the next car body, the discharge port needs to be flipped up and down in sequence to avoid the car body. At this time, the traditional dust removal device often cannot achieve better cooperation.
[0008] In summary, the traditional dust removal device is unable to perform the above-mentioned action coordination due to its fixed design, resulting in low dust removal efficiency.
[0009] Therefore, it is very necessary to invent a dust removal device for the unloading port of a loader. Utility Model Content
[0010] The utility model aims to provide a dust removal device for a discharge port of a loader to solve the problems mentioned in the background technology.
[0011] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0012] The utility model relates to a dust removal device for the discharging port of a loading machine, which comprises two groups of dust removal units that are symmetrically arranged and cooperate to surround the discharging port of the loading machine. Each dust removal unit comprises a support frame, a first transmission mechanism, a connecting plate, a first dust suction port, a mounting plate, a second transmission mechanism, a second dust suction port and a shielding mechanism. The support frame is fixed to the wall between the discharging rooms of the loading machine by bolts, and the first transmission mechanism is fixed on the support frame. The output end of the first transmission mechanism is fixed with the connecting plate. The lower side surface of the end of the connecting plate far away from the support frame is fixed with the first dust suction port, and mounting plates are fixed to both sides of the connecting plate by welding. The second transmission mechanisms are fixed to the upper side surfaces of the mounting plates by bolts, and the output ends of the second transmission mechanisms are fixed with the second dust suction ports. The upper ends of the first dust suction port and the second dust suction port are connected to the input end of an external plastic sintered plate dust collector through air pipes, and the first dust suction port and the second dust suction port are arranged at corresponding positions outside the discharging port. A shielding mechanism is fixed to one side of each second dust suction port close to the discharging port.
[0013] Furthermore, both the first dust suction port and the second dust suction port adopt a hood type with a larger lower part and a smaller upper part. Such a setting facilitates the extraction of dust.
[0014] Furthermore, the first transmission mechanism comprises a first cylinder and a vertical plate. The first cylinder is fixed to the upper side surface of the support frame by bolts. The output end of the first cylinder is fixed to the connecting plate through the vertical plate, and the vertical plate is slidably connected to the support frame. The connecting plate is slidably connected to the support frame through at least one group of first guiding components. Such a setting can adjust the distance between the first dust suction port and the discharging port.
[0015] Furthermore, the second transmission mechanism comprises a second cylinder, an auxiliary plate and a rotating mechanism. The second cylinder is fixed to the upper side surface of the corresponding mounting plate by bolts, and the output end of the second cylinder is fixed to the auxiliary plate by bolts. The auxiliary plate is slidably connected to the mounting plate through at least one group of second guiding components. The rotating mechanism is fixed to the upper side surface of the auxiliary plate, and the output end of the rotating mechanism is fixed with the second dust suction port. Such a setting can adjust the distance between the second dust suction port and the discharging port.
[0016] Furthermore, the rotating mechanism comprises a gearbox, a motor, a rotating column and an extension plate. The gearbox is fixed to the upper side surface of the auxiliary plate by bolts. The input end of the gearbox is fixed to the output end of the motor, and the base of the motor is fixed to the box body of the gearbox by bolts. The output end of the gearbox is connected to the rotating column through gear meshing, and the rotating column is rotatably installed on the auxiliary plate through a support bearing. The extension plate is fixed to the outer side surface of the rotating column by welding, and the other end of the extension plate is fixed with the second dust suction port by bolts. Such a setting can change the state of the second dust suction port.
[0017] Further, the shielding mechanism includes a telescopic curtain, an electromagnet, a reciprocating plate, a clamping plate and an electric bolt. One end of the telescopic curtain is fixed to the corresponding second dust suction port, and electromagnets are fixed on both sides of the other end of the telescopic curtain. Reciprocating plates are fixed to the sides of the electromagnets close to the second dust suction port by bolts. The reciprocating plates are movably arranged inside the corresponding clamping plates, and the clamping plates are fixed to the second dust suction port by bolts. Chutes are formed through the interiors of the reciprocating plates. Electric bolts are fixed to the upper sides of the clamping plates by bolts. The output ends of the electric bolts slide through the chutes formed inside the clamping plates and the reciprocating plates. Such an arrangement can shield the gap between the second dust suction port and the discharge port.
[0018] Compared with the prior art, the utility model has the following beneficial effects:
[0019] When not in use, the utility model can move away from the discharge port and retract to the position of the wall of the loading machine discharge room, effectively saving space and making the loading machine discharge room cleaner and more orderly. When discharging at the discharge port, through the cooperation of the first transmission mechanism and the second transmission mechanism, the first dust suction port and the second dust suction port can be moved to the outside of the discharge port, and then through the cooperation of the first dust suction port, the second dust suction port and the external plastic sintered plate dust collector, the dust generated during the discharging process of the discharge port can be collected. And when the discharge port shakes, the shielding mechanism can act accordingly to prevent dust from passing through the gap between the second dust suction port and the discharge port. When changing to the next car body, the second dust suction port can be moved correspondingly with the displacement of the discharge port through the second transmission mechanism, so that the whole device does not need to be retracted, thus saving valuable time and improving work efficiency.

[0033] Please refer to Figures 1 to 8As shown in the figure, the utility model relates to a dust removal device for the discharging port of a loading machine, which comprises two groups of dust removal units symmetrically arranged and cooperatively surrounding the discharging port of the loading machine. Each group of the dust removal units comprises a support frame 1, a first transmission mechanism 2, a connecting plate 3, a first dust suction port 4, a mounting plate 5, a second transmission mechanism 6, a second dust suction port 7 and a shielding mechanism 8.

[0034] Specifically, the first transmission mechanism 2 comprises a first cylinder 21 and a vertical plate 22. The first cylinder 21 is fixed to the upper side of the support frame 1 by bolts.

The first guiding frame is fixed to the support frame 1 by bolts, and the first sliding block is fixed to the connecting plate 3. When in use, the connecting plate 3 can be driven by the first cylinder 21 to move, so that the first dust suction port 4 approaches or moves away from the discharging port 10.
[0035] Specifically, the second transmission mechanism 6 comprises a second cylinder 61, an auxiliary plate 62 and a rotating mechanism 63. The second cylinder 61 is fixed to the upper side of the corresponding mounting plate 5 by bolts, and the output end of the second cylinder 61 is fixed to the auxiliary plate 62 by bolts; the auxiliary plate 62 is slidably connected to the mounting plate 5 through at least one group of second guiding components. Each group of the second guiding components is composed of a second guiding frame and a second sliding block; the second sliding block is slidably connected to the second guiding frame. The second guiding frame is fixed to the mounting plate 5 by bolts, and the second sliding block is fixed to the auxiliary plate 62; the rotating mechanism 63 is fixed to the upper side of the auxiliary plate 62, and the output end of the rotating mechanism 63 is fixed with the second dust suction port 7. When in use, the auxiliary plate 62 can be driven by the second cylinder 61 to move, so that the second dust suction port 7 approaches or moves away from the discharging port 10.
[0036] Specifically, the rotating mechanism 63 includes a gearbox 631, a motor 632, a rotating column 633, and an extension plate 634. The gearbox 631 is fixed to the upper side of the auxiliary plate 62 by bolts; the input end of the gearbox 631 is fixed to the output end of the motor 632, and the base of the motor 632 is fixed to the housing of the gearbox 631 by bolts; the output end of the gearbox 631 is connected to the rotating column 633 through gear meshing, and the rotating column 633 is rotatably mounted on the auxiliary plate 62 through a support bearing; the outer side of the rotating column 633 is fixed with an extension plate 634 by welding, and the other end of the extension plate 634 is fixed with a second dust suction port 7 by bolts. When in use, the cooperation of the motor 632 and the gearbox 631 can drive the rotating column 633 to rotate, thereby changing the state of the second dust suction port 7, that is, the change between the vertical standby state and the horizontal working state.
[0037] Specifically, the shielding mechanism 8 includes a telescopic curtain 81, an electromagnet 82, a reciprocating plate 83, a clamping plate 84, and an electric bolt 85.

When in use, the electromagnets 82 can adsorb on the discharge port 10, so that the telescopic curtain 81 is unfolded, and the gap between the second dust suction port 7 and the discharge port 10 is shielded by the telescopic curtain 81. Moreover, the reciprocating plate 83 can slide inside the clamping plate 84, so that when the discharge port 10 shakes slightly, the telescopic curtain 81 can still shield the gap between the second dust suction port 7 and the discharge port 10. In addition, when the telescopic curtain 81 needs to be replaced, the output end of the electric bolt 85 can be retracted, so that the reciprocating plate 83 and the telescopic curtain 81 can be removed from the clamping plate 84.
[0038] Please refer to Figures 1-8 As shown, the present utility model is a dust removal device for the discharge port of a loading machine, and its working principle is as follows:
[0039] During installation, first, two dust removal units are respectively arranged on both sides of the discharge port 10, and then fixed to the wall of the loading machine discharge compartment by bolts.
[0040] In the standby state, through the first transmission mechanism 2 and the second transmission mechanism 6, the first dust suction port 4 and the second dust suction port 7 are moved away from the discharge port 10, and through the rotating mechanism 63 inside the second transmission mechanism 6, the second dust suction port 7 is in the vertical standby state.
[0041] During the loading process, first, the first dust suction port 4 is arranged to be in contact with the corresponding side surface of the discharge port 10 through the first transmission mechanism 2. Then, the second dust suction port 7 is in a horizontal working state through the rotating mechanism 63 inside the second transmission mechanism 6. Next, the second dust suction port 7 is brought close to the corresponding side surface of the discharge port 10 through the second transmission mechanism 6, and a corresponding gap is formed between the second dust suction port 7 and the discharge port 10. Then, the gap between the second dust suction port 7 and the discharge port 10 is blocked by the shielding mechanism 8. When the discharge port 10 generates a slight shake, the slight shake will drive the reciprocating plate 83 to slide correspondingly inside the clamping plate 84, and the telescopic curtain 81 will fold and unfold correspondingly, so as to prevent the dust generated during the discharging process from passing through between the second dust suction port 7 and the discharge port 10. Then, through the cooperation of the first dust suction port 4, the second dust suction port 7 and the external plastic sintered plate dust collector, the dust generated during the discharging process of the discharge port 10 is collected.
[0042] When changing to the next wagon 9, since the discharge port 10 needs to perform the actions of flipping up and flipping down in sequence, at this time, the second transmission mechanism 6 drives the two second dust suction ports 7 to move correspondingly, so that the distance between the second dust suction port 7 and the discharge port 10 is always the same, that is, the telescopic curtain 81 can block the gap between the second dust suction port 7 and the discharge port 10 when the discharge port 10 is displaced.
[0043] In the description of this specification, the descriptions referring to terms such as "one embodiment", "example", "specific example", etc. mean that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention.
