Description

Technical Field

[0001] The invention relates to the technical field of car unloading equipment, and more particularly to a dust suppression and material taking device for a negative pressure car unloading machine. Background Art

[0002] When transporting materials in train carriages, the single transport volume is large and the cost is low. However, in practical work, the loading and unloading of some bulk materials such as coal, sand and gravel is not only labor-intensive but also very inefficient. Train bulk material unloading equipment such as tippers, chain bucket unloaders, excavators, horizontal screw unloaders, vertical screw unloaders, etc. all have the problem of clearing residual materials.

[0003] Compared with car dumpers, screw car unloaders have little damage to the car body when unloading coal, and are well adaptable to general car models. The length of the unloading line, the amount of coal received and the output capacity can be flexibly selected according to different needs, and the coal can be unloaded in sections. According to the different overall forms, screw car unloaders can be divided into three types: bridge type, gantry type and single arm type;

[0004] Chinese utility model patent CN202021301097.7 discloses a negative pressure car cleaning machine, including a mobile gantry, a lifting slide, a slide guide device, a lifting device, a negative pressure collection device, a cleaning and material taking device, a hydraulic station and an electrical box; wherein the lifting slide is slidably installed in the middle of the crossbeam of the mobile gantry through the slide guide device; the lifting device is installed on one side of the slide guide device and is connected to the lifting slide through a wire rope; the cleaning and material taking device is detachably installed at the bottom end of the lifting slide, and the cleaning and material taking device is connected to the negative pressure collection device through a material conveying pipeline, and the negative pressure collection device is located on the other side of the slide guide device; the hydraulic station and the electrical box are both installed on the crossbeam of the mobile gantry. The above scheme can realize single-sided cleaning and full-carriage cleaning, without opening the door to clean the remaining materials in the car, and can clean the residual materials at the root of the car, which is efficient and environmentally friendly and liberates labor.

[0005] However, the technical solution of the above patent adopts a method of cooperating multiple disc brushes for cleaning aggregates, but the method of cooperating multiple disc brushes often results in material leakage, so that the material cannot fully approach the herringbone adsorption mechanism, resulting in insufficient material collection; at the same time, when the technical solution of the above patent is used for unloading, only the material on one side can be unloaded. In other existing technologies in the field, there are also solutions for symmetrically setting cleaning mechanisms on both sides, but the symmetrical design not only increases the cost, but also greatly increases the weight of the cleaning device, thereby increasing the load of the equipment;

[0006] At the same time, the technical solution of the above patent lacks a dust suppression mechanism, which will generate a large amount of dust when cleaning materials, causing environmental pollution. If a water mist mechanism is used for dust suppression, it will often lead to an increase in the water content in the material, causing a series of subsequent impacts.

[0007] Therefore, how to provide a dust suppression and material taking device for a negative pressure unloader is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0008] In view of this, the present invention provides a dust suppression and material taking device for a negative pressure unloader to at least solve one of the problems raised in the above background technology section.

[0009] In order to realize the above scheme, the present invention adopts the following technical scheme:

[0010] A dust suppression and material taking device for a negative pressure unloader comprises a lifting slide, a feeding pipe is arranged in the lifting slide, a mounting plate is mounted on the bottom end of the lifting slide through a rotating mechanism, a spiral material collector and a transverse roller brush are mounted on the bottom of the mounting plate, and a movable disc brush mechanism is mounted on the side of the mounting plate;

[0011] The rotating mechanism includes a sleeve, an inner tube, a first slewing bearing, a gear ring and a stepper motor, the lifting slide is fixedly connected to the inner wall of the inner tube, the sleeve is installed on the top of the mounting plate, the inner tube extends into the sleeve, and the first slewing bearing is arranged between the inner tube and the sleeve; the gear ring is installed outside the sleeve, the stepper motor is installed on one side of the lifting slide through a bracket, and a first gear meshing with the gear ring is arranged on the motor shaft of the stepper motor; the feed pipe runs through the mounting plate, the feed pipe passes through the inner tube and the sleeve and extends to the bottom of the mounting plate, and is located at the center of the mounting plate, and the bottom end of the feed pipe is rotatably mounted with a suction sleeve through a second slewing bearing; the spiral feeder is installed below one side of the suction sleeve, the transverse roller brush is installed on the side of the spiral feeder away from the suction sleeve, and the movable disc brush mechanism is installed on the side of the transverse roller brush away from the spiral feeder;

[0012] A dust hood is rotatably installed above the movable disc brush mechanism, and the dust hood is connected with the suction sleeve through a first dust collecting pipe; a dust pipe is installed on the side of the mounting plate opposite to the movable disc brush mechanism, and the dust pipe is connected with the suction sleeve through a second dust collecting pipe, and a strip-shaped dust suction port is opened at the bottom of the dust pipe along its axial direction.

[0013] The present invention improves the cleaning and material-grabbing device in a negative pressure car cleaning machine of the prior art Chinese utility model patent CN202021301097.7. The mounting plate is installed at the bottom end of the lifting slide through a rotating mechanism so that it can rotate at a certain angle. When the car cleaning operation is performed, when the material on one side of the car is unloaded, the material-grabbing device can be rotated 180°, driving the components on the mounting plate to rotate 180° together, so that it can clean and collect the material on the other side of the car, which not only reduces the cost investment, but also reduces the weight of the material-grabbing device, thereby reducing the load on the equipment.

[0014] With the cooperation of the spiral collector, transverse roller brush and movable disc brush mechanism, the material can fully move in the direction of the feed pipe and move to the feed port at the bottom of the feed pipe to the maximum extent, realizing negative pressure suction collection.

[0015] When the mobile disc brush mechanism is collecting materials, the generated dust will be adsorbed by the dust hood installed rotatably above the mobile disc brush mechanism, and enter the suction sleeve through the first dust collecting pipe for collection; due to the presence of the mounting plate, the dust generated by the transverse roller brush will not spread upward, thereby preventing the dust from spreading outward from the inner tube; the dust suction pipe installed on the side of the mounting plate opposite to the mobile disc brush mechanism can collect the dust generated by the transverse roller brush to prevent it from spreading to the outside; since the other two sides of the mounting plate are in contact with the inner walls of the two sides of the car during operation, the dust will not spread outward from the other two sides of the mounting plate, thereby achieving effective dust suppression.

[0016] Preferably, in the above-mentioned dust suppression and material taking device for a negative pressure unloader, the transverse roller brush comprises a roller brush rotating tube, a first hydraulic motor, a nylon wire and steel wire mixed brush sheet, a wire rope brush sheet, a galvanized steel wire brush sheet and a nylon wire brush sheet; the nylon wire and steel wire mixed brush sheets are installed at both ends of the outer tube wall of the roller brush rotating tube; the wire rope brush sheet, the galvanized steel wire brush sheet and the nylon wire brush sheet are arranged in sequence to form a brush sheet group, and the brush sheet group is provided with multiple groups; multiple groups of the brush sheet groups are arranged in sequence and installed on the outer tube wall of the roller brush rotating tube, and multiple groups of the brush sheet groups are located between the nylon wire and steel wire mixed brush sheets at both ends;

[0018] A combination of nylon wire and steel wire mixed brushes, steel wire rope brushes, galvanized steel wire brushes and nylon wire brushes are used. Multiple groups of the brushes are arranged in sequence and installed on the outer tube wall of the roller brush rotating tube, and multiple groups of the brushes are located between the nylon wire and steel wire mixed brushes at both ends, which can achieve a better cleaning effect and a long life of the bristles; at the same time, the steel wire rope brushes can whip the materials collected by the roller brush when rotating to prevent the materials from piling up behind the horizontal roller brush, thereby reducing the height of the material pile and facilitating collection. The first hydraulic motor is built-in, so that the two ends of the horizontal roller brush can be closer to the inner wall of the carriage, enhancing the cleaning effect.

[0019] Preferably, in the above-mentioned dust suppression and material picking device for a negative pressure unloading machine, the movable disc brush mechanism includes a mounting beam, a second hydraulic motor, a second gear, a cylindrical linear guide, a slider, a rack, a third hydraulic motor and a disc brush; wherein two cylindrical linear guides are arranged in parallel, the rack and the cylindrical linear guide are installed in parallel on the mounting beam, and the cylindrical linear guide is located below the rack; two second gears are provided, which are respectively installed on the rotating shafts of two second hydraulic motors, and the two second hydraulic motors are respectively connected to the two sliders, and the second gear is meshed with the rack; the slider is provided with a slide groove matching the cylindrical linear guide, and the cylindrical linear guide is embedded in the slide groove; the third hydraulic motor is installed on the slider through a mounting plate and is located below the second hydraulic motor, and the disc brush is installed on the rotating shaft of the third hydraulic motor; the dust hood is installed on the mounting beam, and the mounting beam is installed on the side of the mounting plate.

The cylindrical linear guide rails are embedded in the slide grooves, so that the sliding is more stable and less affected by the deadweight, and stable sliding can be maintained. When a large piece of solid material is stuck at the meshing point between the second gear and the rack, the vibration motor arranged on the mounting beam can be turned on to drive the slider to vibrate, so as to facilitate the vibration of the stuck solid material and solve the problem of jamming.

[0023] The dust hood is only affected by gravity in the absence of external force, and the barrier rod maintains an angle of 45° with the vertical direction under the action of the limit rod. During the cleaning process, when the movable disc brush mechanism approaches the car wall, the rollers installed on the side of the dust hood through the pin shaft contact the car wall.

When the movable disc brush mechanism is completely close to the car wall, the angle between the dust hood and the vertical direction reaches a minimum value and is greater than 15°. After the movable disc brush mechanism completes the collection at the corner of the car wall, it starts to retreat. At this time, the rollers on the side of the dust hood gradually lose contact with the car wall, and finally the angle between the dust hood and the vertical direction is restored to 45° in the absence of external force.

[0024] Preferably, in the above-mentioned dust suppression and material taking device for a negative pressure car unloader, a roller is installed on the other side of the dust hood opposite to the hinge shaft through a pin shaft.

[0059] Working principle:

[0060] The present invention improves the cleaning and material-collecting device in a negative pressure car cleaning machine of the prior art Chinese utility model patent CN202021301097.7. The mounting plate 4 is mounted on the bottom end of the lifting slide 1 through the rotating mechanism 3 so that it can rotate at a certain angle. When the car cleaning operation is performed, when the material on one side of the car is unloaded, the material-collecting device can be rotated 180°, driving the components on the mounting plate 4 to rotate 180° together, so that it can clean and collect the material on the other side of the car, which not only reduces the cost investment, but also reduces the weight of the material-collecting device, thereby reducing the load on the equipment.

[0061] With the cooperation of the spiral collector 5, the transverse roller brush 6 and the movable disc brush mechanism 7, the material can fully move in the direction of the feed pipe 2 and move to the feed port at the bottom end of the feed pipe 2 to the maximum extent, realizing negative pressure suction collection.

[0062] When the mobile disc brush mechanism 7 is collecting materials, the generated dust will be adsorbed by the dust hood 8 rotatably installed above the mobile disc brush mechanism 7, and enter the suction sleeve 37 through the first dust collecting pipe 81 for collection; the dust generated by the transverse roller brush 6 will not diffuse upward due to the obstruction of the mounting plate 4, thereby preventing the dust from diffusing outward from the inner tube 32; the dust suction pipe 9 installed on the side of the mounting plate 4 opposite to the mobile disc brush mechanism 7 can collect the dust generated by the transverse roller brush 6 to prevent it from diffusing to the outside; since the other two sides of the mounting plate 4 are in contact with the inner walls of the two sides of the car during operation, the dust will not diffuse outward from the other two sides of the mounting plate 4, thereby achieving effective dust suppression.

[0063] The dust hood 8 is only affected by gravity in the absence of external force. The blocking rod 84 maintains an angle of 45° with the vertical direction under the action of the limit rod 85. During the cleaning process, when the movable disc brush mechanism 7 approaches the carriage wall, the roller 86 installed on the side of the dust hood 8 through the pin shaft contacts the carriage wall. When the movable disc brush mechanism 7 continues to approach the carriage wall, the dust hood 8 starts to rotate, and the angle with the vertical direction gradually decreases. When the movable disc brush mechanism 7 is completely close to the carriage wall, the angle between the dust hood 8 and the vertical direction reaches the minimum value and is greater than 15°. After the movable disc brush mechanism 7 completes the collection at the corner of the carriage wall, it starts to retreat. At this time, the roller 86 on the side of the dust hood 8 gradually loses contact with the carriage wall, and finally the angle between the dust hood 8 and the vertical direction is restored to 45° in the absence of external force.

[0064] With the cooperation of the spiral collector 5, the transverse roller brush 6 and the movable disc brush mechanism 7, the material can fully move in the direction of the feed pipe 2 and move to the feed port at the bottom end of the feed pipe 2 to the maximum extent, realizing negative pressure suction collection.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
