Description

Technical Field

[0001] The invention relates to the technical field of sweepers, and particularly proposes an anti-accumulation material sweeper. Background Art

[0002] When the conveyor belt is transporting 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 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, have uneven tension, and even increase the load on the motor.

[0003] At present, when cleaning the surface and inner wall of the conveyor belt, multiple sweepers are used to clean the surface and inner wall of the conveyor belt respectively, which increases the cleaning cost of the conveyor belt. In addition, materials are easily adhered to the sweepers, resulting in incomplete cleaning of the conveyor belt, poor cleaning effect, and reduced service life of the conveyor belt. In addition, when the conveyor belt is loose, the sweeper is likely 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 simultaneously 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 tension effect with the conveyor belt surface.

[0013] In one possible implementation, the transmission assembly includes two vertical grooves on one of the mounting frames corresponding to the cleaning brush rollers, and the upper and lower corresponding rotating shafts and the cleaning brush rollers are inserted into the same vertical groove and connected through a belt pulley.

[0014] In one possible implementation, the movable guide assembly includes three guide columns, one of which is fixedly mounted in the middle of a fixed plate located on one side of the V-shaped scraper opening, and the other two guide columns are symmetrically arranged along the width direction of the conveyor belt and fixedly mounted on another fixed plate.

At the same time, the sweeper also has its own maintenance capability to prevent accumulated materials from adhering to the cleaning brush roller and affecting the cleaning effect of the cleaning brush roller on the conveyor belt. At the same time, the lower side cleaning mechanism and the inner cleaning mechanism are always in close contact with the inner and outer side walls of the conveyor belt under the elastic adaptive force tensioning action of the elastic tensioning part, and always maintain effective cleaning of the conveyor belt, which greatly improves the cleaning effect.

[0021] 2. The end cleaning mechanism of the present invention always maintains an elastically tight state with the side wall of the conveyor belt through its own elastic adaptive force, which can not only scrape and clean the residue on the conveyor belt, but also avoid excessive pressure when it is pressed against the side wall of the conveyor belt, which may cause wear of the rubber layer of the side wall of the conveyor belt. At the same time, it maintains a constant contact pressure with the side wall of the conveyor belt.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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 are within the scope of protection of the present invention.

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

[0032] See Figure 1 A material accumulation prevention cleaner includes: a fixed frame 1, an end cleaning mechanism 3, a lower side cleaning mechanism 4 and an internal cleaning mechanism 5. Two mounting frames 2 are installed on the top of the fixed frame 1 through an elastic tensioning portion 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 internal cleaning mechanism 5 are both installed between the two mounting frames 2.

[0033] After the conveyor belt 7 transports the material to its end for discharge, the end cleaning mechanism 3 elastically contacts the outer side wall of one end of the conveyor belt 7 in the moving direction, and performs preliminary cleaning and scraping of the outer side wall of one end of the conveyor belt 7 in the moving direction, thereby scraping off the material adhering to the conveyor, avoiding material adhesion and leakage, and protecting the conveyor belt 7 and the conveyor roller.

[0034] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4The lower side 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 one of the mounting frames 2 is provided with a driving portion 42 for driving the two cleaning brush rollers 40; the internal 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 part 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 the integrated cleaning of the outer wall of the conveying end end, the inner wall of the lower horizontal section and the outer wall of the conveyor belt 7 by a sweeper, 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 part 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 end, the inner wall of the lower horizontal section, the outer wall of the conveyor belt 7 and the integrated driving of the cleaning brush roller 40 are realized.

[0036] See 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 the sprocket chain 1. One of the cleaning brush rollers 40 rotates and passes through the mounting frame 2 and is connected to the conveying roller of the adjacent conveyor belt 7 through the sprocket chain 2 (not shown in the figure). 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 cleans the conveyor belt 7 in the width direction. The conveyor belt 7 is not only cleaned by the V-shaped scraper 50 during its own movement, but also is subjected to the scraping force of the V-shaped scraper 50, and the residue is pushed to both sides for discharge, which greatly improves the efficiency of cleaning the inner wall of the conveyor belt 7 and the discharge speed.

[0037] See Figure 1 and Figure 3The 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 wear of the conveyor belt 7. The lower end of the arc-shaped scraper 30 is equipped with multiple connecting frames 31 evenly arranged along its length direction. A mounting groove 32 is provided on the fixed frame 1. The ends of the multiple connecting frames 31 slide into the mounting groove 32 and are then equipped with connecting plates 33. Multiple compression springs 34 are evenly arranged between the connecting plates 33 and the mounting groove 32.

[0038] Under the action of multiple compression springs 34, the arc scraper 30 always maintains an elastically tight state against the side wall of the conveyor belt 7, so that the arc scraper 30 can scrape and clean the residue on the conveyor belt 7, and avoid excessive pressure when the arc scraper 30 is pressed against the side wall of the conveyor belt 7, which may cause wear of the rubber layer of 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 deviates slightly or shakes, it can continue to adhere to the side wall to avoid scraping omissions.

[0039] See Figure 1 and Figure 3 The fixed frame 1 is also equipped with an auxiliary supporting portion 35 for supporting the bottoms of multiple connecting frames 31. The auxiliary supporting portion 35 includes multiple supporting seats 350 evenly arranged and installed on the fixed frame 1. The supporting seats 350 are slidably connected to the connecting frames 31 in a one-to-one manner and support the bottoms of the connecting frames 31. A supporting plate 351 is installed on the frame of the conveyor belt 7 to support the ends of the multiple supporting seats 350, thereby improving the supporting force of the connecting frames 31 and the curved scraper 30.

[0040] See Figure 1 、 Figure 2 and Figure 5 The movable guide portion 51 includes a rotating shaft 510 corresponding to the cleaning brush roller 40 and located directly above it. The two rotating shafts 510 are rotatably connected between the two mounting frames 2. Two fixed plates 511 are installed on the V-shaped scraper 50. A matching movable guide component is provided between the two fixed 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 through a transmission component. The transmission component includes two vertical grooves corresponding to the cleaning brush rollers 40 on one of the mounting frames 2. The upper and lower corresponding rotating shafts 510 and the cleaning brush rollers 40 are inserted into the same vertical groove and then connected through a belt pulley.

[0041] During the rotation, the cleaning brush roller 40 drives the rotating shaft 510 to rotate through the belt pulley. When the rotating shaft 510 rotates, it drives the V-shaped scraper 50 to move back and forth along the width direction of the conveyor belt 7 through the moving guide assembly, thereby cleaning the inner side wall of the conveyor belt 7.

[0042] See Figure 1 、 Figure 2 and Figure 3 The movable guide assembly includes three guide posts 520, one of which is fixedly mounted on the middle of a fixed plate 511 located on one side of the opening of the V-shaped scraper 50, and the other two guide posts 520 are fixedly mounted on the other fixed plate 511 symmetrically along the width direction of the conveyor belt 7. Guide grooves 521 corresponding to the guide posts 520 are provided on the two rotating shafts 510. The guide grooves 521 are composed of two inclined grooves symmetrically arranged along the axis of the rotating shaft 510 and connected at both ends. The guide posts 520 are slidably connected to the corresponding guide grooves 521.

[0043] When the rotating shaft 510 rotates, the three guide posts 520 slide in cooperation with the corresponding guide grooves 521 , thereby driving the V-shaped scraper 50 to move back and forth, thereby improving the stability of the movement of the V-shaped scraper 50 .

[0044] When the guide post 520 cooperates with the guide groove 521: when the guide post 520 moves along one end of one of the inclined grooves of the guide groove 521 to the other end of the inclined groove of the guide 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 guide post 520 enters the other inclined groove of the guide groove 521, and then moves along the inclined groove to its other end, driving the V-shaped scraper 50 to move in the opposite direction for reset, so that the rotating shaft 510 drives the V-shaped scraper 50 to move back and forth during the rotation process, and at the same time realizes the function of integrated driving of the lower cleaning mechanism 4 and the internal cleaning mechanism 5.

[0045] See Figure 2 and Figure 3 An auxiliary support assembly is slidably connected between the two fixed 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 a support wheel 530 located at the top corner of the V-shaped scraper 50 also fixedly sleeved on the other rotating shaft 510. The support wheel 530 is slidably connected to the adjacent fixed plate 511 through a connecting seat 531 rotatably connected thereon. 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] See Figure 2 and Figure 3 The cleaning part 41 includes two brush plates 410, which are used to clean the two cleaning brush rollers 40 respectively. The brush plates 410 are slidably connected to a mounting plate 411 fixedly connected to the mounting frame 2. Ear plates 412 are fixedly installed at both ends of the brush plate 410. The ear plates 412 are slidably mounted on the corresponding rotating shaft 510 and are fixedly connected to the V-shaped scraper 50 or the corresponding fixed plate 511.

[0047] When the V-shaped scraper 50 moves along the width direction of the conveyor belt 7, the brush plate 410 moves axially along the cleaning brush roller 40 driven by the V-shaped scraper 50 to clean the cleaning brush roller 40, to prevent the cleaning brush roller 40 from leaving material on the bristles of the cleaning brush roller 40 when cleaning the conveyor belt 7, thereby affecting 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] See Figure 1 and Figure 5 The elastic tensioning part 6 includes symmetrically distributed installation cavities 60 opened on the fixing frame 1, and a support frame 61 is installed at the bottom of the installation frame 2, which slides up and down and is inserted into the installation cavity 60. A plurality of springs 62 are evenly arranged between the support frame 61 and the installation cavity 60, and a supporting assembly 63 is installed between the two installation frames 2. The spring 62 is used to push the support frame 61 and the supporting assembly 63 to tension the conveyor belt 7.

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

[0050] The mounting frame 2 and the support frame 61 push the two supporting rollers 630 to always keep close to the conveyor belt 7 under the pushing action of the spring 62 below them, to prevent the V-shaped scraper 50 or the cleaning brush roller 40 from detaching from the conveyor belt 7 when the conveyor belt 7 becomes loose, making it difficult to effectively clean the conveyor belt 7.

[0051] See Figure 1-Figure 5 Working principle: After the conveyor belt 7 transports the material to its end for discharging, the end cleaning mechanism 3 performs preliminary cleaning and scraping on 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 preliminary cleaning, the two cleaning brush rollers 40 clean the residual materials on the outer side wall of the conveyor belt 7 again after the preliminary cleaning.

[0053] At the same time, 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 is scraped and cleaned by the V-shaped scraper 50. The scraped material moves along the inclined surface of the V-shaped scraper 50 and is discharged. The V-shaped scraper 50 also moves along the width direction of the conveyor belt 7 under the guidance of 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 residues through the V-shaped scraper 50 during its own movement, but also is subjected to the moving scraping force of the V-shaped scraper 50, and pushes the residues to both sides for discharge.

[0054] In addition, the V-shaped scraper 50 also drives the cleaning part 41 to clean the residual material on the cleaning brush roller 40, to prevent the material from remaining on the bristles of the cleaning brush roller 40 when the cleaning brush roller 40 cleans the conveyor belt 7, thereby affecting the cleaning effect of the cleaning brush roller 40 on the conveyor belt 7.
