Description

Technical Field

[0001] The invention relates to the technical field of sweepers, and specifically proposes a sweeper to prevent material accumulation. Background Art

[0002] When the conveyor belt is conveying materials, the materials (especially sticky, moist or fine particles) are easy to adhere to the surface of the conveyor belt. After the conveyor belt is unloaded, some materials remain on the belt surface and flow back to the conveyor roller with the conveyor belt, causing material accumulation. The accumulated materials will not only adhere to the surface of the conveyor belt, but may also be rolled in between the conveyor roller and the conveyor belt, accelerating the wear of the conveyor belt and the conveyor roller. At the same time, the accumulated materials will cause the conveyor belt to deviate, the tension is uneven, and even increase the motor load.

[0003] At present, when cleaning the surface and the inner wall of the conveyor belt, multiple cleaners are used to clean the surface and the inner wall of the conveyor belt respectively, which increases the cleaning cost of the conveyor belt, and materials are easily adhered to the cleaner, resulting in incomplete cleaning of the conveyor belt, poor cleaning effect, and reduced service life of the conveyor belt; and when the conveyor belt is loose, the cleaner is easy to have poor contact with the conveyor belt surface or detach from the conveyor belt surface, making it difficult to achieve the expected cleaning effect.

[0004] Therefore, there is an urgent need for an anti-material accumulation sweeper that can perform multiple integrated cleanings on the surface, inner wall side and end of the conveyor belt at the same time. The sweeper should also have its own maintenance capabilities to prevent material from adhering to it, and can adaptively adjust its tensioning effect with the conveyor belt surface.

[0021] 2. The end cleaning mechanism in the present invention always maintains an elastically tightened state with the side wall of the conveyor belt through its own elastic self-adaptive force. It can not only scrape and clean the residues on the conveyor belt, but also avoid excessive pressure when it is in contact with the side wall of the conveyor belt, which may cause wear of the rubber layer on the side wall of the conveyor belt. At the same time, it also maintains a constant contact pressure with the side wall of the conveyor belt. Even if the conveyor belt is slightly deviated or jittered, it can continuously fit the side wall to avoid missed scraping.

[0022] 3. The cleaning brush roller in the present invention drives the V-shaped scraper to reciprocate along the width direction of the conveyor belt through the moving guiding part, so as to clean the conveyor belt in the width direction. This enables the conveyor belt to not only clean the residues through the V-shaped scraper 50 during its own movement, but also be subjected to the moving scraping force of the V-shaped scraper, and push the residues to both sides for discharging. This greatly improves the cleaning efficiency of the inner side wall of the conveyor belt and the discharging speed. Description of the Drawings

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Refer to Figure 1 , a material accumulation prevention cleaner, comprising: a fixed frame 1, an end cleaning mechanism 3, a lower side cleaning mechanism 4 and an inner cleaning mechanism 5. Two mounting frames 2 are installed on the top of the fixed frame 1 through an elastic tensioning part 6; the end cleaning mechanism 3 is arranged on the fixed frame 1 and is elastically slidably connected to the fixed frame 1, and the lower side cleaning mechanism 4 and the inner cleaning mechanism 5 are both installed between the two mounting frames 2.

[0033] After the conveyor belt 7 conveys the material to its end for discharging, the end cleaning mechanism 3 elastically abuts against the outer side wall of one end of the conveyor belt 7 in the moving direction, and preliminarily cleans and scrapes the outer side wall of one end of the conveyor belt 7 in the moving direction, so as to scrape off the material adhered to the conveyor belt, avoid the adhesion and leakage of the material, and protect the conveyor belt 7 and the conveying roller.

[0034] Refer to Figure 1 , Figure 2 , Figure 3 And Figure 4The lower cleaning mechanism 4 includes two cleaning brush rollers 40 symmetrically distributed along the length direction of the conveyor belt 7 and rotatably connected between the two mounting frames 2. A cleaning portion 41 for cleaning the cleaning brush rollers 40 is also provided between the two mounting frames 2, and a driving portion 42 for driving the two cleaning brush rollers 40 is provided on one of the mounting frames 2; the inner cleaning mechanism 5 includes a V-shaped scraper 50 with an opening facing the moving direction of the conveyor belt 7 and a moving guide portion 51. The lower end surface of the V-shaped scraper 50 is in close contact with the inner side wall of the lower horizontal section of the conveyor belt 7. The material that falls on the inner side wall of the lower horizontal section of the conveyor belt 7 during the movement of the conveyor belt 7 is scraped and cleaned by the V-shaped scraper 50, and the scraped material moves along the inclined surface of the V-shaped scraper 50 and is discharged.

[0035] The driving unit 42 drives the two cleaning brush rollers 40 to clean the outer wall of the conveyor belt 7, and the V-shaped scraper 50 cleans the inner wall of the lower horizontal section of the conveyor belt 7, thereby realizing integrated cleaning of the outer wall of the conveying end portion of the conveyor belt 7, the inner wall of the lower horizontal section and the outer wall by one cleaner, which greatly improves the convenience and efficiency of cleaning the residual materials on the conveyor belt 7. At the same time, the V-shaped scraper 50 also drives the cleaning unit 41 to clean the residual materials on the cleaning brush roller 40, so that the materials remaining on the conveyor belt 7 can be effectively cleaned after the cleaning brush roller 40, and at the same time, the outer wall of the conveying end portion of the conveyor belt 7, the inner wall of the lower horizontal section, the outer wall cleaning and the integrated driving of the cleaning brush roller 40 are realized.

[0036] See also Figure 4 The driving part 42 includes a connecting groove 420 opened on one of the mounting frames 2. The ends of the two cleaning brush rollers 40 are inserted into the connecting groove 420 and then driven by sprocket chain 1. After one of the cleaning brush rollers 40 rotates and passes through the mounting frame 2, it is connected to the conveying roller of the adjacent conveyor belt 7 by sprocket chain 2 (not shown in the figure), so that the cleaning brush roller 40 rotates synchronously with the conveying roller under the connection action of the driving part 42, without the need for an external driving source, and the cleaning brush roller 40 drives the V-shaped scraper 50 to reciprocate along the width direction of the conveyor belt 7 through the moving guide part 51, and moves and cleans the conveyor belt 7 in the width direction, so that the conveyor belt 7 not only cleans the residue through the V-shaped scraper 50 during its own movement, but also can be subjected to the moving scraping force of the V-shaped scraper 50, and pushes the residue to both sides for discharge, which greatly improves the cleaning efficiency and discharge speed of the inner wall of the conveyor belt 7.

[0037] See also Figure 1 and Figure 3, the end cleaning mechanism 3 includes an arc-shaped scraper 30 for cleaning the outer side wall of the end of the conveyor belt 7. The scraping head of the arc-shaped scraper 30 is made of rubber to avoid abrasion of the conveyor belt 7. A plurality of connecting frames 31 are uniformly arranged along the length direction at the lower end of the arc-shaped scraper 30. An installation groove 32 is formed on the fixed frame 1. After the ends of the plurality of connecting frames 31 slide into the installation groove 32, a connecting plate 33 is installed. A plurality of compression springs 34 are uniformly arranged between the connecting plate 33 and the installation groove 32.

[0038] Under the action of the plurality of compression springs 34, the arc-shaped scraper 30 always maintains an elastically abutted state with the side wall of the conveyor belt 7, so that the arc-shaped scraper 30 can scrape and clean the residues on the conveyor belt 7, and avoid excessive pressure when the arc-shaped scraper 30 abuts against the side wall of the conveyor belt 7, resulting in wear of the rubber layer on the side wall of the conveyor belt 7. At the same time, it also maintains a constant contact pressure with the side wall of the conveyor belt 7. Even if the conveyor belt 7 is slightly deflected or vibrates, it can continuously fit the side wall to avoid missed scraping.

[0039] Refer to Figure 1 And Figure 3 , an auxiliary supporting part 35 for supporting the bottoms of the plurality of connecting frames 31 is further installed on the fixed frame 1. The auxiliary supporting part 35 includes a plurality of uniformly arranged supporting seats 350 installed on the fixed frame 1. The supporting seats 350 are slidably connected to the connecting frames 31 one by one and support the bottoms of the connecting frames 31. A supporting plate 351 for supporting the ends of the plurality of supporting seats 350 is installed on the frame of the conveyor belt 7, thereby improving the supporting force of the connecting frames 31 and the arc-shaped scraper 30.

[0040] Refer to Figure 1 、 Figure 2 And Figure 5 , the moving guiding part 51 includes rotating shafts 510 corresponding to the cleaning brush rollers 40 one by one and located directly above them. The two rotating shafts 510 are rotatably connected between the two mounting frames 2. Two fixing plates 511 are installed on the V-shaped scraper 50. A moving guiding component is provided between the two fixing plates 511 and the two rotating shafts 510. The V-shaped scraper 50, the two rotating shafts 510 and the two cleaning brush rollers 40 are connected by a transmission component. The transmission component includes two vertical grooves corresponding to the cleaning brush rollers 40 one by one formed on one of the mounting frames 2. The rotating shafts 510 and the cleaning brush rollers 40 corresponding up and down are inserted into the same vertical groove and are connected by belt pulley transmission.

[0041] During the rotation of the cleaning brush roller 40, the rotating shaft 510 is driven to rotate through the belt pulley. When the rotating shaft 510 rotates, the V-shaped scraper 50 is driven to reciprocate along the width direction of the conveyor belt 7 through the moving guiding component, so as to clean the inner side wall of the conveyor belt 7.

[0042] Refer to Figure 1 、Figure 2 With Figure 3 , the moving guiding assembly includes three guiding columns 520. One of the guiding columns 520 is fixedly installed in the middle of the fixing plate 511 on one side of the opening of the V-shaped scraper 50, and the other two guiding columns 520 are symmetrically and fixedly installed on the other fixing plate 511 along the width direction of the conveyor belt 7. Guiding grooves 521 corresponding to the guiding columns 520 one by one are formed on both rotating shafts 510. The guiding groove 521 is composed of two inclined grooves symmetrically arranged along the axis of the rotating shaft 510 and communicated at both ends. The guiding column 520 is slidably connected with the corresponding guiding groove 521.

[0043] When the rotating shaft 510 rotates, the three guiding columns 520 respectively perform sliding cooperation with their corresponding guiding grooves 521, thereby driving the V-shaped scraper 50 to perform reciprocating movement and improving the stability of the movement of the V-shaped scraper 50.

[0044] When the guiding column 520 cooperates with the guiding groove 521: when the guiding column 520 moves from one end of one of the inclined grooves of the guiding groove 521 to the other end of the inclined groove of the guiding groove 521, the V-shaped scraper 50 moves to one side in the width direction of the conveyor belt 7; when the rotating shaft 510 continues to rotate, the guiding column 520 enters the other inclined groove of the guiding groove 521, and then moves along the inclined groove to its other end, driving the V-shaped scraper 50 to move in the reverse direction for resetting. Thus, when the rotating shaft 510 rotates, it drives the V-shaped scraper 50 to perform reciprocating movement, and at the same time realizes the function of integrated driving of the lower cleaning mechanism 4 and the inner cleaning mechanism 5.

[0045] Refer to Figure 2 With Figure 3 , an auxiliary support assembly is slidably connected between the two fixing plates 511 and the two rotating shafts 510. The auxiliary support assembly includes two support wheels 530 fixedly sleeved on the rotating shaft 510 on one side of the opening of the V-shaped scraper 50, and one support wheel 530 fixedly sleeved on the other rotating shaft 510 at the vertex angle of the V-shaped scraper 50. The support wheel 530 is slidably connected with the adjacent fixing plate 511 through a connecting seat 531 rotatably connected thereto. The support wheel 530 is used to support the middle part of the rotating shaft 510 and the V-shaped scraper 50, thereby improving the supporting force of the rotating shaft 510 and the V-shaped scraper 50.

[0046] Refer to Figure 2 With Figure 3 , the cleaning part 41 includes two brush plates 410, and the two brush plates 410 are respectively used to clean the two cleaning brush rollers 40. An installation plate 411 fixedly connected with the installation frame 2 is slidably connected to the brush plate 410. Ear plates 412 are fixedly installed at both ends of the brush plate 410. The ear plates 412 are slidably sleeved on the corresponding rotating shafts 510 and fixedly connected with the V-shaped scraper 50 or the corresponding fixing plate 511.

[0047] When the V-shaped scraper 50 moves along the width direction of the conveyor belt 7, the brush plate 410 is driven by the V-shaped scraper 50 to move axially along the cleaning brush roller 40 to clean the cleaning brush roller 40, preventing materials from remaining on the bristles of the cleaning brush roller 40 when the cleaning brush roller 40 cleans the conveyor belt 7, which affects the cleaning effect of the cleaning brush roller 40 on the conveyor belt 7. An inclined baffle 20 is installed on the mounting frame 2, and the inclined baffle 20 is used to guide the residues removed by the reciprocating movement of the V-shaped scraper 50 to prevent the residues pushed out by the V-shaped scraper 50 from flying around.

[0048] Refer to Figure 1 And Figure 5 , the elastic tensioning part 6 includes symmetrically distributed mounting cavities 60 opened on the fixed frame 1. The bottom of the mounting frame 2 is provided with a support frame 61 that slides up and down and inserts into the mounting cavity 60. A plurality of springs 62 are uniformly arranged between the support frame 61 and the mounting cavity 60. A supporting component 63 is installed between the two mounting frames 2, and the springs 62 are used to push the support frame 61 and the supporting component 63 to tension the conveyor belt 7.

[0049] Refer to Figure 1 And Figure 2 , the supporting component 63 includes two supporting rollers 630 rotatably connected between the two mounting frames 2 through ear seats. The two cleaning brush rollers 40 are located between the two supporting rollers 630, and the supporting rollers 630 are used to push and tension the conveyor belt 7.

[0050] The mounting frame 2 and the support frame 61 are pushed by the springs 62 below them to keep the two supporting rollers 630 always in contact with the conveyor belt 7, preventing the V-shaped scraper 50 or the cleaning brush roller 40 from separating from the conveyor belt 7 when the conveyor belt 7 becomes slack, resulting in difficulty in effectively cleaning the conveyor belt 7.

[0051] Refer to Figures 1 - 5 , working principle: After the conveyor belt 7 conveys the materials to its end for discharging, the end cleaning mechanism 3 initially cleans and scrapes the outer side wall of one end of the conveyor belt 7 in the moving direction.

[0052] When the conveyor belt 7 continues to move after the initial cleaning, the two cleaning brush rollers 40 clean the materials remaining after the initial cleaning of the outer side wall of the conveyor belt 7 again.

[0053] Meanwhile, the lower end surface of the V-shaped scraper 50 is in close contact with the inner side wall of the lower horizontal section of the conveyor belt 7. During the movement of the conveyor belt 7, the materials that fall on the inner side wall of its lower horizontal section are scraped and cleaned by the V-shaped scraper 50. The scraped materials move along the inclined surface of the V-shaped scraper 50 and then fall off. The V-shaped scraper 50 also moves along the width direction of the conveyor belt 7 under the guiding action of the moving guiding part 51, so as to clean the conveyor belt 7 in the width direction. This enables the conveyor belt 7 to not only clean the residues through the V-shaped scraper 50 during its own movement, but also be subjected to the moving scraping force of the V-shaped scraper 50, and the residues are pushed to both sides for discharging.

[0054] Moreover, the V-shaped scraper 50 also drives the cleaning part 41 to clean the residues on the cleaning brush roller 40, preventing the residues from remaining on the bristles of the cleaning brush roller 40 when the cleaning brush roller 40 cleans the conveyor belt 7, which may affect the cleaning effect of the cleaning brush roller 40 on the conveyor belt 7.
