Description

Technical Field

[0001] The present invention relates to the technical field of sweepers, in particular to an independent shock-absorbing composite sweeper. Background Art

[0002] A sweeper is a device used to clean residual materials on the conveyor. During the material conveying process of the belt conveyor, if residual attached materials enter the roller or roller bearing seat, it will accelerate the wear of the bearing. The materials sticking to the surface of the roller or roller will tear and roughen the conveyor belt surface adhesive, accelerating the wear and damage of the conveyor belt. Therefore, the use of a sweeper is particularly important.

[0003] At present, if the return belt is to be cleaned, a single layer of blades can only block the return belt material floating on the upper layer due to the impact of the return belt material, and cannot clean the material adhering to the belt surface. The cleaning effect is limited. In order to ensure an effective cleaning effect, at least two cleaners are required.

[0004] But in many working conditions, for example, the drum diameter is small and the funnel position problem is seen Figure 10 As shown in the figure, the position of the fixed roller frame is not suitable. For example, the use of a beam type often leads to a lack of installation position for the second sweeper. It is necessary to push it within a very compact range, that is, within a 250mm wide range or a 4 o'clock-5 o'clock range, to place a composite multi-blade sweeper with two or even three blades on a bar. For this reason, we propose an independent shock-absorbing composite sweeper. Summary of the Invention

[0005] The purpose of the present invention is to provide an independent shock-absorbing composite sweeper, which has the advantages of three layers of blades combined in one rod and good cleaning effect, and solves the problem of small installation space resulting in no installation position for sweepers with two or even three blades.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an independent shock-absorbing composite sweeper, comprising a mounting base, wherein the left and right ends of the front face of the mounting base are fixedly connected with fixed covers, the inner side of the fixed cover is fixedly connected with a large-diameter torsion round tube, the middle end of the top of the large-diameter torsion round tube is fixedly connected with an intermediate component, the upper end of the intermediate component is fixedly installed with a first blade, the rear side of the mounting base is fixedly installed with a first mounting seat and a second connecting seat that are alternately arranged and adjacent, the inner sides of the first mounting seat and the second connecting seat are respectively fixedly installed with a first connecting block and a second connecting block, and one side of the first connecting block and the second connecting block is respectively fixedly installed with a third blade and a second blade, the left and right ends of the inner cavity of the large-diameter torsion round tube are fixedly installed with a small-diameter torsion round tube, and the left and right ends of the small-diameter torsion round tube are provided with a composite torsion tensioner.

[0007] Preferably, a shielding plate is fixedly mounted on the upper end of the mounting base plate, and the longitudinal section of the shielding plate is a V-shaped structure.

[0008] Preferably, the first blade has an arc structure and is made of polyurethane.

[0009] Preferably, the first mounting seat and the second connecting seat have the same size and specifications, and rubber base pads are provided on the inner sides of the first mounting seat and the second connecting seat.

[0010] Preferably, the length of the third blade is 1.1 to 1.4 times the length of the second blade.

[0011] Preferably, the composite torsion tensioner includes a mounting plate movably connected to both ends of the outer surface of the large-diameter torsion tube through bearings, a fixing rod is fixedly installed on the inner surface of one end of the mounting plate, and a limiting pin is provided at the end of the fixing rod away from the mounting plate.

[0012] Preferably, the outer surface of the fixed rod is sleeved with a first steering sleeve and a second steering sleeve, and one side of the outer surface of the first steering sleeve and the second steering sleeve is fixedly connected with a first guide rod and a second guide rod respectively.

[0013] Preferably, the outer surface of the first guide rod is provided with a first toggle plate, a first pad, a first spring and two first locking nuts in sequence from the first steering sleeve downward, and the outer surface of the second guide rod is provided with a second toggle plate, a second pad, a second spring and two second locking nuts in sequence from the second steering sleeve upward.

[0014] Preferably, one end of the small-diameter torsion tube away from the large-diameter torsion tube is fixedly installed with a first movable sleeve fixedly connected to the first toggle plate and a second movable sleeve fixedly connected to the second toggle plate in sequence from near to far by bolts.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention can make three layers of blades work on a rod by installing a base plate and setting a large-diameter torsion round tube. While the composite torsion tensioner ensures the tensioning force, the first blade can block the return material floating on the upper layer of the belt surface when the return material impacts, and the second blade and the third blade can "scrape" the material adhered to the belt surface, thereby ensuring the cleaning effect of the cleaner.

[0016] 2. The present invention can realize the cleaning ability of three layers of blades in a small space. It is easy to use, has good cleaning effect, long service life, and is conducive to replacement, maintenance and market promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figures 1-10As shown, the present invention provides a technical solution: an independent shock-absorbing composite sweeper, comprising a mounting base 1, the left and right ends of the front face of the mounting base 1 are fixedly connected with a fixed cover 7, the inner side of the fixed cover 7 is fixedly connected with a large-diameter torsion circular tube 2, the middle end of the top of the large-diameter torsion circular tube 2 is fixedly connected with an intermediate component 6, the upper end of the intermediate component 6 is fixedly installed with a first blade 5, the rear side of the mounting base 1 is fixedly installed with a first mounting seat 13 and a second connecting seat 14 that are alternately arranged and adjacent, the inner sides of the first mounting seat 13 and the second connecting seat 14 are fixedly installed with a first connecting block 8 and a second connecting block 15 respectively, and one side of the first connecting block 8 and the second connecting block 15 are fixedly installed with a third blade 11 and a second blade 12 respectively, the left and right ends of the inner cavity of the large-diameter torsion circular tube 2 are fixedly installed with a small-diameter torsion circular tube 3, and the left and right ends of the small-diameter torsion circular tube 3 are provided with a composite torsion tensioner 4.

[0024] This technical solution: After the installation plate 28 of the composite torsion tensioner 4 is installed, the sweeper (such as Figure 1 As shown) cooperates with the belt, and by arranging the first mounting seat 13 and the second connecting seat 14 in an alternating and adjacent manner, the third blade 11 and the second blade 12 can be mounted on the mounting base 1 (as shown) through the cooperation of the first connecting block 8 and the second connecting block 15. Figures 2 to 6 As shown), through the setting of the intermediate member 6, it can form a whole with the first blade 5, and can improve the overall strength of the first blade 5 through its own metal material characteristics, thereby ensuring the service life of the first blade 5 (as shown in FIG. Figures 2 to 5 As shown), in this cleaner Figure 1 After installation as shown, and with the assistance of the small diameter torsion tube 3 and the composite torsion tensioner 4, the tip of the first blade 5 can be in close contact with the belt surface, while the second blade 12 and the third blade 11 can contact the belt surface in a "scraping" manner to remove materials with strong adhesion (such as Figure 1 and Figure 2 as well as Figure 9 As shown), the belt Figure 2 When working in the rotation direction shown, the cooperation of the small-diameter torsion tube 3 and the composite torsion tensioner 4 can block the return material floating on the upper layer of the belt surface when the return material impacts the first blade 5, and the second blade 12 and the third blade 11 can "scrape" the material adhering to the belt surface, thereby ensuring the cleaning effect of the cleaner and meeting the following requirements: Figure 10 Use as shown.

[0025] It is understandable that Figure 10 The content is that during on-site use, the width of the lower opening of the funnel is limited. In order to ensure that the material can fall smoothly into the lower opening, the positions of the funnel and the roller are relatively fixed. Figure 10 This area in the center circle is often too small to fit a second sweeper.

[0026] See also Figures 1-9 As shown, a shielding plate 9 is fixedly mounted on the upper end of the mounting base plate 1 , and the longitudinal section of the shielding plate 9 is a V-shaped structure.

[0027] This technical solution: through the setting of the shield plate 9, the cleaned belt material can be blocked when the tip of the first blade 5 contacts the belt surface and works, preventing it from entering between the second blade 12 and the third blade 11 below, so as to avoid affecting the "scraping" cleaning method of the second blade 12 and the third blade 11.

[0028] See also Figures 1-6 As shown, the first blade 5 adopts an arc structure, and the first blade 5 is made of polyurethane. The first mounting seat 13 and the second connecting seat 14 are of the same size, and a rubber base pad is provided on the inner side of the first mounting seat 13 and the second connecting seat 14. The length of the third blade 11 is 1.1 to 1.4 times the length of the second blade 12.

[0029] This technical solution: By adopting an arc structure and a material of polyurethane for the first blade 5, the angle between the first blade 5 and the belt surface when it is first used can be ensured, and the service life of the first blade 5 can be improved. The rubber base pad is arranged on the inner side of the first mounting seat 13 and the second connecting seat 14, and with the cooperation of the first connecting block 8 and the second connecting block 15, after the third blade 11 and the second blade 12 are installed, the rubber base pad can buffer the vibration generated by the third blade 11 and the second blade 12 when "scraping" and cleaning, while ensuring the service life of the belt, and can always ensure the cleaning effect of the third blade 11 and the second blade 12 on the belt, and the third blade 11 and the second blade 12 have different lengths, and cooperate with the alternating and adjacent first mounting seat 13 and the second connecting seat 14, which can make the "scraped" belt material quickly discharged, avoiding the occurrence of material piling.

[0030] See also Figures 1-9As shown, the composite torsion tensioner 4 includes a mounting plate 28 movably connected to the outer surface of the large-diameter torsion tube 2 at both ends through a bearing. A fixing rod 10 is fixedly mounted on the inner surface of one end of the mounting plate 28. A limit pin 26 is provided at the end of the fixing rod 10 away from the mounting plate 28. The outer surface of the fixing rod 10 is sleeved with a first steering sleeve 29 and a second steering sleeve 24. One side of the outer surface of the first steering sleeve 29 and the second steering sleeve 24 is fixedly connected to a first guide rod 30 and a second guide rod 21 respectively. The outer surface of the first guide rod 30 is downwardly directed from the first steering sleeve 29 A first toggle plate 16, a first pad 25, a first spring 31 and two first locking nuts 27 are arranged in sequence. The outer surface of the second guide rod 21 is sequentially provided with a second toggle plate 19, a second pad 23, a second spring 22 and two second locking nuts 20 from the second steering sleeve 24 upward. The end of the small-diameter torsion tube 3 away from the large-diameter torsion tube 2 is fixed with a first movable sleeve 17 fixedly connected to the first toggle plate 16 and a second movable sleeve 18 fixedly connected to the second toggle plate 19 by bolts from near to far.

[0031] The present technical solution is that the sweeper can be installed by setting the mounting plate 28. When the first blade 5 vibrates and twists during use, the first blade 5 can drive the large-diameter torsion tube 2 to twist through the intermediate member 6. When the large-diameter torsion tube 2 twists, it will drive the small-diameter torsion tube 3 to twist. When the small-diameter torsion tube 3 twists, it will drive the first movable sleeve 17 and the first toggle plate 16 and the second movable sleeve 18 and the second toggle plate 19 to twist. At this time, due to the fixed position of the mounting plate 28, the position of the fixed rod 10 remains unchanged. When the first toggle plate 16 and the second toggle plate 19 twist, one end thereof will slide on the outer surface of the first guide rod 30 and the second guide rod 21 respectively. The first guide rod 30 and the second guide rod 21 are respectively restricted by the first locking nut 27 and the second locking nut 20. Under the cooperation of the first pad 25 and the second pad 23, the torsionally sliding first toggle plate 16 and the second toggle plate 19 will compress or pull the first spring 31 and the second spring 22 respectively (such as Figures 7 to 8 As shown), the torsion is buffered, and with the cooperation of the first spring 31 and the second spring 22 in composite tensioning, the tip of the first blade 5 can always be in contact with the belt surface, thereby ensuring the use effect of the present cleaner.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
