Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belt cleaning, in particular to an adaptive sweeper. Background Art

[0002] Conveyor belts, also known as transport belts, are composite products made of rubber, fiber, metal, or plastic and fabric that carry and transport materials. They are widely used in industries such as cement, coking, metallurgy, chemical engineering, and steel where conveying distances are short and volumes are low.

[0003] During the conveying process, the conveyor belt will have residues left by the transported objects on its surface. The residues will contaminate the surface of the conveyor belt, and the accumulated residues will cause wear on the surface of the conveyor belt, accelerating the damage of the conveyor belt. Therefore, a cleaning device is required to clean the conveyor belt.

[0004] Traditional belt conveyor cleaning methods utilize a cleaner installed at the conveyor's head discharge point to remove material particles adhering to the return working surface. Currently available cleaning devices rely on a rigid physical contact cleaning principle. However, due to the long-term friction between the scraper and the material on the outer contact surface of the belt, the belt surface can harden and slip, accelerating the aging of the conveyor belt's carrying surface.

[0005] In view of this, there is an urgent need for an adaptive sweeper. Utility Model Content

[0006] In view of the problems existing in the prior art, the present invention solves the problem with the following technical structure.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] An adaptive sweeper includes: a plurality of scraper assemblies, each of which includes a mounting seat, a blade holder, a scraper, and an elastic assembly, wherein the blade holder is rotatably mounted on the mounting seat, the scraper is mounted on the blade holder, and the elastic assembly is used to apply an elastic force to the blade holder to rotate toward one side of the scraper blade;

[0009] The scrapers are distributed in a straight line.

[0010] It is further characterized in that

[0011] It also includes a cross bar, and the mounting seat is provided with a mounting hole, and a plurality of the mounting seats are sleeved on the cross bar through the mounting holes.

[0012] A limiting strip is provided on the ring side of the crossbar, and the extending direction of the limiting strip is consistent with the axial direction of the crossbar. A limiting hole is provided on one side of the mounting hole of the mounting seat, and the limiting strip is passed through the limiting hole.

[0013] Both sides of the mounting seat are provided with a straight groove, and the knife seat is provided with a mounting shaft, and the two ends of the mounting shaft are respectively arranged in the two straight grooves.

[0014] A mounting plate is provided on the mounting seat, and a screw is threadedly connected to the mounting plate. The axial direction of the screw is consistent with the extension direction of the I-shaped groove. The screw is passed through the mounting shaft, and the axial direction of the screw is perpendicular to the axial direction of the mounting shaft. A nut is provided on the side of the screw away from the mounting plate.

[0015] The knife seat is provided with a sleeve ring, and the scraper is inserted in the sleeve ring.

[0016] A tightening bolt is threadedly connected to the collar, and one end of the tightening bolt abuts against the scraper.

[0017] The knife seat is rotatably connected to the mounting shaft.

[0018] The elastic component is a torsion spring, which is arranged on the mounting shaft. One end of the torsion spring is arranged on the mounting shaft, and the other end is against the knife seat.

[0019] It also includes two connecting seats and two pull rods respectively arranged at both ends of the cross bar. Both ends of the cross bar are provided with slides, and the two connecting seats are provided with slide rails extending in the vertical direction. The two slides are respectively slidably arranged on the slide rails of the two connecting seats, and the two pull rods are slidably arranged on the connecting seats. The bottom end of the pull rod is connected to the end of the cross bar, the axial direction of the pull rod is consistent with the extension direction of the slide rail, and a spring is sleeved on the pull rod, and the spring provides thrust for the pull rod to move upward.

[0020] The above structure of the utility model can achieve the following beneficial effects:

[0021] Since the knife seat is rotatably arranged on the mounting seat, when the return working surface of the conveyor belt is uneven, if the horizontal height of the return working surface of the conveyor belt becomes low or the material is firmly adhered, the scraper is subjected to greater resistance, causing the scraper to rotate toward the side where the return working surface of the conveyor belt is moving, thereby achieving an avoidance effect. If the horizontal height of the return working surface of the conveyor belt becomes high, the resistance encountered by the scraper becomes smaller, and the elastic component causes the scraper to rotate toward the side away from the return working surface of the conveyor belt, thereby achieving a compensation effect, thereby ensuring the cleaning effect of the conveyor belt. In this way, the scraper has the function of adapting itself according to the situation of the return working surface of the conveyor belt, causes less damage to the surface of the conveyor belt, and extends the service life of the conveyor belt.

[0027] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0028] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or equipment.

[0029] The following is combined with Figure 1-4 This application is described in further detail.

[0030] refer to Figure 1-4The adaptive sweeper shown in the figure comprises: a plurality of scraper assemblies, the scraper assemblies comprising a mounting seat 1, a knife seat 2, a scraper 3 and an elastic assembly, the knife seat 2 is rotatably arranged on the mounting seat 1, the scraper 3 is arranged on the knife seat 2, and the elastic assembly is used to apply an elastic force to the knife seat 2 to rotate toward one side of the blade of the scraper 3; the plurality of scrapers 3 are distributed in a straight line. When installing, the scrapers 3 of the plurality of scraper assemblies are arranged in parallel at the bottom of the return working surface of the conveyor belt. When the conveyor belt moves, the material residue on the surface of the conveyor belt is scraped off by the scraper 3. Since the knife seat 2 is rotatably arranged on the mounting seat 1, when the return working surface of the conveyor belt is uneven, if the conveyor belt When the horizontal height of the return working surface of the conveyor belt becomes lower or encounters firmly adhered materials, the scraper 3 is subjected to greater resistance, causing the scraper 3 to rotate toward the side where the return working surface of the conveyor belt moves (compressing the elastic component), thereby achieving adaptive adjustment or avoidance. If the horizontal height of the return working surface of the conveyor belt becomes higher, the resistance encountered by the scraper 3 becomes smaller, and the elastic component causes the scraper 3 to rotate toward the side away from the return working surface of the conveyor belt, thereby achieving compensation and ensuring the cleaning effect of the conveyor belt. In this way, the scraper 3 has the function of adapting itself according to the situation of the return working surface of the conveyor belt, causing less damage to the surface of the conveyor belt and extending the service life of the conveyor belt.

[0031] like Figure 1 As shown, in order to arrange the scrapers 3 of multiple scraper assemblies in parallel, this embodiment also includes a cross bar 5, and a mounting hole 11 is opened on the mounting seat 1. Several mounting seats 1 are mounted on the cross bar 5 through the mounting hole 11, and the mounting seats 1 of multiple scraper assemblies are connected in series through the cross bar 5. In order to ensure that the multiple scrapers 3 are at the same angle, a limiting strip 51 is provided on the ring side of the cross bar 5, and the extension direction of the limiting strip 51 is consistent with the axial direction of the cross bar 5. The mounting seat 1 is provided with a limiting hole 12 on one side of the mounting hole 11, and the limiting strip 51 is passed through the limiting hole 12, so that the mounting seat 1 can only be mounted on the cross bar 5 at a unique angle.

[0032] like Figure 2-3 As shown, the specific installation method between the mounting seat 1 and the knife seat 2 is as follows: a straight groove 13 is provided on both sides of the mounting seat 1, and a mounting shaft 6 is provided on the knife seat 2. The two ends of the mounting shaft 6 are respectively provided in the two straight grooves 13, and the knife seat 2 is rotatably connected to the mounting shaft 6, and the elastic component is a torsion spring 4, which is provided on the mounting shaft 6. One end of the torsion spring 4 is provided on the mounting shaft 6, and the other end rests on the knife seat 2. In this way, when the scraper 3 encounters a large resistance, the knife seat 2 compresses the torsion spring to rotate the scraper 3. When the resistance disappears or becomes smaller, the elastic force of the torsion spring 4 causes the knife seat 2 to rotate in the direction of movement away from the return working surface of the conveyor belt (a limiting component for limiting the rotation angle of the knife seat 2 is provided on the mounting seat 1 to ensure that the blade of the scraper 3 contacts the return working surface of the conveyor belt, for example, the side of the knife seat 2 away from the torsion spring 4 rests on the mounting seat 1).

[0033] like Figure 2-4 As shown, in order to complete the cleaning of the return working surface of the conveyor belt at different heights, a mounting plate 14 is provided on the mounting seat 1, and a screw 7 is threadedly connected to the mounting plate 14. The axial direction of the screw 7 is consistent with the extension direction of the I-shaped groove 13. The screw 7 is passed through the mounting shaft 6, and the axial direction of the screw 7 is perpendicular to the axial direction of the mounting shaft 6. The screw 7 is provided with a nut on the side of the mounting shaft 6 away from the mounting plate 14. In this way, the screw 7 can be rotated to make the mounting shaft 6 move in the two I-shaped grooves 13 to adjust the height of the knife seat 2, so as to achieve the purpose of adjusting the height of the scraper 3 to adapt to the cleaning work of the return working surface of the conveyor belt at different heights.

[0034] Further optimization is, Figure 2-3 As shown, a collar 21 is provided on the knife holder 2, and the scraper 3 is inserted in the collar 21 so that the scraper 3 will not fall off during the cleaning process. In order to facilitate the installation and removal of the scraper 3, a tightening bolt 22 is threadedly connected to the collar 21, and one end of the tightening bolt 22 is in contact with the scraper 3. By tightening the tightening bolt 22, the scraper 3 can be locked and made movable.

[0035] Further optimization is, Figure 1 and Figure 4 As shown, it also includes two connecting seats 8 and two pull rods 9 respectively arranged at both ends of the cross bar 5. A slide plate 52 is provided at both ends of the cross bar 5. The two connecting seats 8 are provided with a slide rail 81 extending in the vertical direction. The two slide plates 52 are respectively slidably set on the slide rails 81 of the two connecting seats 8. The two pull rods 9 are slidably set on the connecting seats 8. The bottom end of the pull rod 9 is connected to the end of the cross bar 5. The axial direction of the pull rod 9 is consistent with the extension direction of the slide rail 81. A spring 91 is sleeved on the pull rod 9, and the spring 91 provides the pull rod 9 with a thrust for upward movement.

[0036] In summary, since the knife seat 2 is rotatably arranged on the mounting seat 1, when the return working surface of the conveyor belt is uneven, if the horizontal height of the return working surface of the conveyor belt becomes lower or the material is firmly adhered, the scraper 3 is subjected to greater resistance, causing the scraper 3 to rotate toward the side of the return working surface of the conveyor belt (compressing the elastic component) to achieve the avoidance effect. If the horizontal height of the return working surface of the conveyor belt becomes higher, the resistance encountered by the scraper 3 becomes smaller, and the elastic component causes the scraper 3 to rotate toward the side away from the return working surface of the conveyor belt to achieve the compensation effect, ensuring the cleaning effect of the conveyor belt. In this way, the scraper 3 has the function of adapting itself according to the situation of the return working surface of the conveyor belt, causes less damage to the surface of the conveyor belt, and extends the service life of the conveyor belt.

[0037] The above are only preferred embodiments of the present application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations directly derived or imagined by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the scope of protection of the present invention.
