Description

Technical Field

[0001] The present application relates to the technical field of belt conveyors, and in particular to a return ground material cleaning machine for belt conveyors. Background Art

[0002] Belt conveyor, also known as belt conveyor, is widely used in various industries such as machinery, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, and food.

[0003] At present, the belt conveyor mainly includes a driving roller, a supporting roller and a conveyor belt. The conveyor belt is set on the outside of the driving roller and the supporting roller. The driving roller is driven by an electric motor, and the conveyor belt is dragged by the friction between the driving roller and the conveyor belt. In the process of material conveying by the belt conveyor, the conveyor belt on the upper side of the belt conveyor conveys the material to the discharge end, and then conveys the material from the discharge end to the head funnel. At this time, the conveyor belt bypasses the driving roller and moves in the reverse direction. The conveyor belt on the lower side of the belt conveyor is the return conveyor belt of the belt conveyor.

[0004] When the material conveyed by the belt conveyor is sticky, adhesive or has high humidity, the material accumulated on the conveyor belt will press the bottom material onto the conveyor belt, causing some of the material to stick to the conveyor belt. These materials are difficult to fall off the conveyor belt at the unloading end, but will continue to be transported along the return conveyor belt. However, with the vibration of the belt conveyor and the gravity of the material itself, some of the material attached to the return conveyor belt will fall to the ground under the belt conveyor, and this part of the material will cause environmental pollution problems.

[0005] Based on this problem, existing belt conveyors often have sweepers on the conveyor belts. The sweepers remove materials on the conveyor belts by scraping or washing, thereby reducing the residual materials on the return conveyor belts. However, a small amount of material will still fall to the ground, and the sweeper cannot remove this part of the material, so this part of the material will still have an impact on the environment. Summary of the invention

[0006] The present application provides a return ground cleaning machine for a belt conveyor, the purpose of which is to remove materials that have fallen to the ground and reduce the impact of the belt conveyor's material transportation on the environment.

[0007] The present application provides a belt conveyor return ground cleaning machine adopts the following technical solution: A belt conveyor return ground cleaning machine comprises a shell, a travel drive mechanism is provided on the shell, and the travel drive mechanism is used to drive the shell to move along its own length direction; a driving roller group is provided on the shell, and a cleaning belt is sleeved on the outer side of the driving roller group, and the driving roller group is used to drive the cleaning belt to rotate and transport along the length direction of the shell; a plurality of scrapers are provided on the cleaning belt, and the plurality of scrapers are arranged in sequence at intervals along the length direction of the cleaning belt; a semicircular shell is provided on one side in the length direction of the shell, and an arc-shaped material guiding channel is formed between the semicircular shell and the cleaning belt, and the arc-shaped material guiding channel connects the space above and below the cleaning belt, and the arc-shaped material guiding channel is used to guide the material below the cleaning belt to the upper side of the cleaning belt.

[0008] By adopting the above technical solution, firstly, the cleaning machine is installed under the belt conveyor through the cooperation of the outer shell, the driving roller group and the cleaning belt. The material on the return conveyor belt in the belt conveyor will fall onto the cleaning belt. Under the action of the driving roller group, the cleaning belt will transport the material back to the head funnel, thereby realizing the transportation of part of the material dropped by the belt conveyor.

[0009] Secondly, the material cleaner cooperates with the cleaning belt through the arc-shaped material guide channel. When the driving roller group drives the cleaning belt to work, the scraper on the lower side of the cleaning belt scrapes up the material on the ground and pushes it toward the direction of the arc-shaped material guide channel, and then the scraper pushes the material into the arc-shaped material guide channel. Under the joint action of the arc-shaped material guide channel and the scraper, the material is transported to the upper side of the cleaning belt, and then under the continuous transportation of the cleaning belt, the material is re-transported to the head funnel.

[0010] The setting of the travel drive mechanism enables the sweeper to move to the position that needs to be cleaned, and then after the material falls to the ground, the travel drive mechanism drives the cleaning mechanism to move to the corresponding position. At this time, the cleaning mechanism can transport the material on the ground to the upper side of the cleaning belt, which can transport the material on the ground to the head funnel in advance.

[0011] Therefore, through the cooperation of the shell, the travel drive mechanism, the drive roller group, the cleaning belt and the arc-shaped guide channel, the materials dropped to the ground can be cleared, and the impact of the belt conveyor conveying materials on the environment can be reduced.

[0015] By adopting the above technical solution, the matching arrangement of the mounting bolts and the long straight holes facilitates the adjustment of the position of the deadweight sealing plate in the vertical direction to ensure that both sides of the shell in the width direction remain sealed. Moreover, when the deadweight sealing plate is worn too seriously, the position of the deadweight sealing plate can be adjusted to ensure that both sides of the shell in the width direction always remain sealed.

[0017] By adopting the above technical solution, the travel drive mechanism cooperates with a plurality of wheel groups and a drive assembly. When the drive assembly drives the corresponding wheel group, the transmission shaft drives the corresponding two travel wheels to rotate, which can drive the entire sweeper to move.

[0018] Optionally, the driving roller group includes an electric roller and a head roller, the axial directions of the electric roller and the head roller are both arranged along the width direction of the outer shell, the electric roller and the head roller are arranged at intervals along the length direction of the outer shell, the cleaning belt is arranged on the outside of the electric roller and the head roller, and the electric roller is coaxially connected to the driving motor.

A plurality of filter layers are arranged in the filter box 76, and the plurality of filter layers are located between the air return pipe 77 and the air inlet pipe 74. In this embodiment, the air extraction member 73 adopts a fan.

[0077] The implementation principle of the embodiment of the present application is: when the material is conveyed by the cleaning machine, the vacuum piece 73 is started, the vacuum piece 73 blows the air into the air outlet pipe 75, the air outlet pipe 75 inputs the gas into a plurality of dust blowing pipes 72, and the air is blown into the arc-shaped material guide channel 6 through the plurality of dust blowing pipes 72. At this time, the dust attached to the inner wall of the cleaning belt 4 and the semicircular shell 5 can be blown off, and then the blown off dust or the attached material dust is sucked into the filter box 76 through the plurality of dust suction pipes 71, and then the filter layer in the filter box 76 filters the air, and the dust-separated air is transported to the vacuum piece 73 through the air inlet pipe 74, which can realize air circulation.
