Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and specifically to a cleaning device for belt conveyors. Background Technology

[0002] Belt conveyors are general-purpose equipment that achieves continuous material transport through the cyclical movement of a conveyor belt. They are widely used in construction, mining and other fields. In concrete transportation, concrete needs to be transported from the mixing point to the construction point via a conveyor belt, and its conveying efficiency and equipment stability directly affect the construction progress.

[0003] During the material conveying process of belt conveyors, a common problem is material adhesion to the conveyor belt surface. Specifically, concrete often adheres to the surface of the lower conveyor belt. This adhered concrete passes synchronously with the lower conveyor belt over the lower idler rollers. During this process, the adhered concrete exerts a squeezing effect on the lower idler rollers and also tends to adhere to the surface of the lower idler rollers, ultimately causing the surface of the lower idler rollers to be rough or the height of each idler roller to be inconsistent. This directly leads to obstruction of the conveyor belt and prevents it from running smoothly. This not only wastes the conveyed material but also increases the failure rate of the belt conveyor, reduces the working efficiency of the conveyor, and makes the conveyor belt transport no longer smooth. At the same time, the concrete adhering to the lower conveyor belt will also continuously fall to the ground during transportation, causing pollution to the construction site environment.

[0004] Therefore, it is necessary to provide a cleaning device for belt conveyors. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a cleaning device for belt conveyors to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a cleaning device for a belt conveyor, comprising a conveyor body, a cleaning mechanism located below the conveyor body, the cleaning mechanism comprising a movable frame, a collection box, a scraper, an adjusting component, and a brush roller, wherein the bottom of the scraper is hinged to the movable frame, the collection box is located on one side of the scraper and is connected to the bottom of the scraper, and the other side of the scraper is connected to the adjusting component, which controls the scraper to swing left and right around the hinge point, so that the top of the scraper contacts the lower surface of the conveyor belt on the conveyor body, and is adaptable to conveyors with different inclination angles; the movable frame is also provided with a lifting component, and the brush roller is rotatably mounted on the top of the two lifting components in the front-back direction, for controlling the up-and-down movement of the brush roller through the lifting components, so that the brush roller contacts the lower surface of the conveyor belt on the conveyor body.

[0007] Furthermore, the adjustment assembly includes a central screw, a slider, a first motor, and a connecting rod. The moving frame has a groove along the left-right direction. The central screw is rotatably installed in the groove. The slider is threadedly connected to the central screw and is adapted to slide in the groove. One end of the central screw is drivenly connected to the first motor. The connecting rod is inclinedly hinged between the scraper and the slider.

[0008] Furthermore, the lifting assembly includes an outer sleeve, an inner screw, an adjusting sleeve, and a top plate. The outer sleeve is rotatably mounted on the movable frame in a vertical direction. The inner screw is fitted inside the outer sleeve, and the top of the inner screw extends vertically upward and is fixed to the top plate at its end. The adjusting sleeve is disposed on the outer sleeve and the inner screw, and rotating the adjusting sleeve drives the inner screw to move up and down.

[0009] Furthermore, a bearing seat is fixed on the top plate, and a rotating shaft is rotatably mounted on the bearing seats of the front and rear top plates. The brush roller is fixedly mounted on the rotating shaft, and one end of the rotating shaft is connected to a second motor to drive the brush roller to rotate. The direction of rotation of the brush roller is opposite to the running direction of the conveyor belt of the belt conveyor.

[0010] Furthermore, the lower part of the adjusting sleeve is rotatably mounted on the outer sleeve, the upper inner diameter of the adjusting sleeve is smaller than the lower inner diameter, and its upper part is threadedly connected to the inner screw.

[0011] Furthermore, the scraper has a crescent-shaped arc structure, and the side of the scraper near the collection box is concave inward. When the scraper scrapes off the concrete adhering to the conveyor belt, the concrete is guided down along its concave surface and falls into the collection box.

[0012] Furthermore, the bottom of the mobile frame is equipped with lockable casters.

[0013] The beneficial effects of the above technical solution are as follows: The cleaning device for belt conveyors provided by this utility model, with its scraper and corresponding adjustment components, achieves efficient scraping and self-guiding collection, smoothly guiding the scraped concrete to the collection box, effectively solving the problems of easy clogging and material splashing of traditional flat scrapers, and realizing the integration of scraping and collection; at the same time, it can also precisely control the tilt angle of the scraper, ensuring that no matter how the tilt angle of the conveyor changes, the scraper can always maintain the best contact state with the belt surface, realizing all-round adaptive fitting, greatly improving scraping efficiency and versatility.

[0014] A brush roller is installed after the scraper, running in the opposite direction to the belt conveyor. The reverse rotation generates stronger shearing force, effectively removing sticky residues that are difficult for the scraper to remove, achieving deep and thorough secondary cleaning. In addition, the height of the brush roller is adjustable, which not only allows the brush roller to adapt to conveyor belts of different heights, but also allows for precise control of contact pressure. While ensuring cleaning effect, it effectively avoids excessive wear on the brush bristles and conveyor belt, extending the service life of the equipment. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Example 1: This example aims to provide a cleaning device for belt conveyors to solve the common problem of material adhering to the surface of the conveyor belt, thereby achieving cleaning and maintenance of the conveyor belt. For example... Figure 1-4 As shown, the cleaning device for a belt conveyor provided in this embodiment includes a cleaning mechanism located below the main body of the conveyor. The cleaning mechanism includes a movable frame 2, a collection box 4, a scraper 5, an adjustment component, and a brush roller 6, etc. The bottom of the movable frame 2 is provided with lockable casters 3. Pushing the movable frame 2 can lock it in the position to be cleaned below the main body of the conveyor.

[0018] A scraper 5 is hinged to the movable frame 2. The tilt angle of the scraper 5 can be adaptively adjusted by an adjustment component connected to the scraper 5 to accommodate different inclinations of the conveyor body, ensuring that the top of the scraper 5 always contacts the lower surface of the conveyor belt 102 on the conveyor body. Specifically, as shown... Figure 2 and 3 As shown, the adjustment assembly includes a central screw 10, a slider 8, a first motor 9, and a connecting rod 7. The moving frame 2 has a groove along the left and right direction. The central screw 10 is rotatably installed in the groove along the left and right direction. The slider 8 is threadedly connected to the central screw 10 and is adapted to slide in the groove. One end of the central screw 10 is connected to the first motor 9 for transmission.

[0019] The connecting rod 7 is inclinedly hinged between the scraper 5 and the slider 8. That is, one end of the connecting rod 7 is hinged to the top of the scraper 5, and the other end is hinged to the back of the scraper 5. The collection box 4 is located on one side of the scraper 5 and is connected to the bottom of the scraper 5. In this embodiment, the scraper 5 has a crescent-shaped arc structure, and the side of the scraper 5 near the collection box 4 is concave inward.

[0020] In this embodiment, the scraper is configured such that the controller controls the first motor 9 to rotate forward and backward, thereby driving the central screw 10 to rotate. This causes the slider 8 to move back and forth within the groove, and under the action of the connecting rod 7, the scraper 5 swings left and right around its bottom hinge shaft. This causes the scraper 5 to contact the lower surface of the conveyor belt 102 and scrape off the concrete adhering to the conveyor belt 102. After the scraper 5 scrapes off the concrete adhering to the conveyor belt 102, the concrete is guided down its concave surface and falls into the collection box 4, facilitating the collection of waste.

[0021] Furthermore, a lifting assembly is also provided on the movable frame 2. The brush roller 6 is rotated and mounted on top of the lifting assembly in the front-to-back direction, thereby controlling the height of the brush roller 6 through the lifting assembly, so that the brush roller 6 contacts the lower surface of the conveyor belt 102 for secondary cleaning. Figure 3 and 4 As shown, in this embodiment, the lifting assembly includes an outer sleeve 14, an inner screw 11, an adjusting sleeve 12, and a top plate 13. The outer sleeve 14 is vertically rotatably mounted on the movable frame 2. The inner screw 11 is fitted inside the outer sleeve 14, and the top of the inner screw 11 extends vertically upward and is fixed to the top plate 13. A bearing seat is fixed on the top plate 13. A rotating shaft is rotatably fitted on the bearing seats of the front and rear top plates 13. The brush roller 6 is fixedly fitted on the rotating shaft, and the rotation direction of the brush roller 6 is opposite to the running direction of the conveyor belt 102 of the conveyor 1. One end of the rotating shaft is connected to a second motor 15. The second motor 15 is driven to rotate by the controller to drive the rotating shaft and the brush roller 6 to rotate, thereby performing a secondary cleaning of the conveyor belt 102 after the first scraping by the brush roller 6.

[0022] In addition, an adjusting sleeve 12 is provided on the outer sleeve 14 and the inner screw 11. Specifically, the lower part of the adjusting sleeve 12 is rotatably fitted on the outer sleeve 14. The upper inner diameter of the adjusting sleeve 12 is smaller than the lower inner diameter, and its upper part is threadedly connected to the inner screw 11. Thus, by rotating the adjusting sleeves 12 on both sides simultaneously, the inner screw 11 can move up and down vertically inside the outer sleeve 14 to adjust the height of the brush roller 6 so that it matches the height of the conveyor belt 102.

[0023] Working principle description: The cleaning device for belt conveyors provided in this embodiment, in actual application, involves pushing the movable frame 2 and using its bottom casters 3 to move it to the section below the conveyor 1 that needs cleaning, taking care to avoid the idler rollers 101 on the conveyor 1. After positioning, the casters 3 are locked to fix the entire cleaning mechanism in the working position. The controller starts the first motor 9, driving the central screw 10 to rotate. The screw drives the slider 8 on it to move horizontally within the groove, which in turn pushes the scraper 5 to swing around its hinge point until the top edge of the scraper 5 adheres to the lower surface of the conveyor belt 102, forming an effective scraping angle. Then, manually rotate the adjusting sleeves 12 on both sides synchronously to adjust the brush roller 6 to a suitable height so that its bristles can contact the lower surface of the conveyor belt 102. Then, when the conveyor belt 102 of the conveyor 1 is running, the scraper 5, which has been adjusted to the correct angle, can scrape off the concrete adhering to its surface. The scraped material slides smoothly down along the concave arc surface of the scraper 5 and is guided into the collection box 4 to achieve centralized recycling of dirt and avoid secondary pollution. At the same time, the second motor 15 is started to drive the brush roller 6 to rotate. The brush roller 6 performs a deep scrubbing of the conveyor belt 102 after one scraping to remove residual fine particles. After cleaning, the moving frame 2 can be removed.

[0024] The cleaning device for belt conveyors provided in this embodiment achieves efficient and flexible cleaning of the conveyor belt through the synergistic effect of a scraper and a liftable, counter-rotating brush roller. It can not only adaptively adjust to fit the conveyor belt at different inclination angles to ensure scraping effectiveness, but also generate a strong shearing action through the counter-rotating brush roller to deeply remove stubborn residues. Its convenient height adjustment mechanism ensures a balance between cleaning effect and equipment safety. At the same time, the cleaning mechanism can be quickly deployed to the working position, making it flexible and convenient.

[0025] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
