[0030] Reference below Figures 1 to 4 A belt conveyor having a belt cleaning mechanism according to an embodiment of the present invention is described.

[0031] refer to Figures 1 to 4 As shown, the belt conveyor with a belt cleaning mechanism according to an embodiment of the present invention includes a mounting frame 100 , a belt 200 and a cleaning mechanism 300 .

[0032] The mounting frame 100 is provided with two transmission wheels 101 , which can be arranged side by side, and one of the transmission wheels 101 can be transmission-connected to a driving motor, and the driving motor drives the transmission wheel 101 to rotate.

[0033] The belt 200 is installed between the two transmission wheels 101, that is, the two ends of the belt 200 are respectively arranged around the two transmission wheels 101. The belt 200 has a conveying section 201 and a return section 202. The conveying section 201 and the return section 202 are both located between the two transmission wheels 101. The conveying section 201 can be located above the return section 202. The conveying section 201 is used to convey materials, and the return section 202 is used for return. The driving motor drives the transmission wheels 101 to rotate, and the two transmission wheels 101 can drive the belt 200 to move through friction.

[0034] The cleaning mechanism 300 includes a spray pipe 301, which is installed on the mounting frame 100. The spray pipe 301 can be connected to a water inlet pipe, which can be connected to a water source. The spray pipe 301 can extend along the width direction of the belt 200. The spray pipe 301 is provided with a plurality of nozzles 302, which are arranged along the length direction of the spray pipe 301. The nozzles 302 are directed toward the return section 202, for example, they can be directed toward the surface of the return section 202 that is away from the conveying section 201. In this way, the cleaning water sprayed from the nozzle 302 can clean the surface of the belt 200 used to convey materials, and the cleaning effect is good. Among them, the spray pipe 301 can swing around its own axis to adjust the spray direction of the nozzle 302, so that the cleaning water can be sprayed to the position to be cleaned in the return section 202 in multiple different directions. For example, when the belt 200 is provided with an anti-slip structure, the residue may be located on the side of the anti-slip structure close to the feed end, and the residue may also be located on the side of the anti-slip structure close to the discharge end. By swinging the spray pipe 301, the cleaning water can be sprayed to the position to be cleaned in the return section 202 in multiple different directions. In this way, even if the residue is located at different positions of the anti-slip structure, it can be sprayed with cleaning water, so that the cleaning is more comprehensive and thorough, and the cleaning effect is better.

[0035] In this embodiment, when the belt 200 needs to be cleaned, the belt 200 is driven to move by the driving wheel 101. During the movement of the belt 200, cleaning water is input into the spray pipe 301. The spray pipe 301 can spray cleaning water toward the position of the return section 202 close to the spray pipe 301 through the nozzle 302 for cleaning. During the movement of the belt 200, other parts of the belt 200 can be moved to the vicinity of the spray pipe 301 in sequence, so that various parts of the belt 200 can be cleaned without damaging the belt 200. In addition, during the cleaning process, the spray pipe 301 is swung back and forth around its own axis, so that the spray direction of the nozzle 302 can be adjusted, so that the cleaning water can be sprayed to the position to be cleaned of the belt 200 in multiple different directions, so that the cleaning is more comprehensive and thorough, and the cleaning effect of the belt 200 is better.

[0036] refer to Figure 2 As shown, in some embodiments of the present invention, the cleaning mechanism 300 also includes two guide rollers 303 and a tensioning roller 304. The two guide rollers 303 are rotatably installed on the mounting frame 100 and are arranged along the conveying direction of the belt 200. The guide rollers 303 extend along the width direction of the belt 200. The guide rollers 303 are attached to the surface of the return section 202 that is away from the conveying section 201. The tensioning roller 304 is rotatably installed on the mounting frame 100 and extends along the width direction of the belt 200. The tensioning roller 304 is located below between the two guide rollers 303. The tensioning roller 304 is attached to the surface of the return section 202 that is facing the conveying section 201.

[0037] In this embodiment, the belt 200 can be tensioned by two guide rollers 303 and a tensioning roller 304, which not only improves the conveying effect of the belt 200, but also improves the cleaning effect of the belt 200. In addition, due to the tensioning of the tensioning roller 304, the portion of the belt 200 between the two guide rollers 303 protrudes downward, and then the cleaning water sprayed onto the return section 202 by the nozzle 302 can fall downward under the action of its own gravity when the belt 200 moves between the two guide rollers 303, thereby effectively removing the cleaning water on the belt 200.

[0038] refer to Figure 2 As shown, in some embodiments of the present invention, the portion of the return section 202 between the guide roller 303 and the tension roller 304 forms a cleaning section 203, two spray pipes 301 are provided, the two spray pipes 301 are respectively located on the opposite sides of the two cleaning sections 203, and the nozzles 302 face the cleaning sections 203. For example, the return section 202 forms one of the cleaning sections 203 between the tension roller 304 and one of the guide rollers 303, and the return section 202 forms another cleaning section 203 between the tension roller 304 and the other guide roller 303. The two cleaning sections 203 may extend vertically or extend obliquely downward, the two spray pipes 301 are respectively located on the opposite sides of the two cleaning sections 203, and the nozzles 302 on the spray pipes 301 face the adjacent cleaning sections 203.

[0039] In this embodiment, the return section 202 is configured in this way, and when it passes near one of the spray pipes 301, it can be initially cleaned by the cleaning water sprayed from the nozzle 302 on the spray pipe 301, and when it passes near another spray pipe 301, it can be cleaned again by the cleaning water sprayed from the nozzle 302 on the spray pipe 301, so that the cleaning is more comprehensive and thorough, and the cleaning effect of the belt 200 is better. In addition, the cleaning water sprayed from the nozzle 302 can just flow down from the bottom ends of the two cleaning sections 203, so as to better remove the cleaning water on the belt 200.

[0040] refer to Figure 2 and Figure 3As shown, in some embodiments of the present invention, a transmission component 305 is provided between the tension roller 304 and the two spray pipes 301. When the belt 200 drives the tension roller 304 to rotate, the tension roller 304 drives the two spray pipes 301 to swing simultaneously through the transmission component 305. When the belt 200 moves, the friction between the belt 200 and the tension roller 304 drives the tension roller 304 to rotate, and the tension roller 304 drives the two spray pipes 301 to swing through the transmission component 305, without the need to set up an additional drive member to drive the spray pipes 301 to swing, the structure is simpler, and the cost is lower. Secondly, the movement of the belt 200 and the swing of the spray pipe 301 are synchronous, so the cleaning effect of the belt 200 is better. In addition, the two spray pipes 301 also swing simultaneously, which can further improve the cleaning effect.

[0041] refer to Figure 2 As shown, in some embodiments of the present invention, the swing directions of the two spray pipes 301 are opposite. For example, when one of the spray pipes 301 swings clockwise, the other spray pipe 301 can swing counterclockwise, so that after the return section 202 of the belt 200 passes by the two spray pipes 301 in sequence, generally, each position of the return section 202 can be cleaned by the cleaning water sprayed by the nozzles 302 of the two spray pipes 301, and the cleaning is more comprehensive and thorough.

[0042] refer to Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the transmission assembly 305 includes a cam 306, two gears 307 and a rack 308, the cam 306 is connected to one end of the tensioning roller 304, the two gears 307 are respectively connected to one end of the two spray pipes 301 corresponding to the cam 306, the rack 308 is vertically slidably installed on the mounting frame 100, the rack 308 extends vertically, and the rack 308 is located between the two gears 307, wherein the two gears 307 are respectively meshed with two sides of the rack 308, and the top end of the cam 306 abuts against the bottom end of the rack 308. For example, the rotation axis of the cam 306 can be coaxial with the center line of the tensioning roller 304, the gear 307 can be arranged at one end of the spray pipe 301 close to the cam 306, the gear 307 can be coaxial with the spray pipe 301, the rack 308 can be arranged between the two gears 307 and located above the cam 306, and meshing teeth can be provided on both sides of the rack 308, which mesh with the corresponding gears 307.

[0043] When the distance between the position where the cam 306 abuts against the rack 308 and the rotation axis of the cam 306 gradually increases, the rack 308 will slide upward, thereby driving the two gears 307 to rotate synchronously, thereby driving the two spray pipes 301 to swing upward at the same time; when the distance between the position where the cam 306 abuts against the rack 308 and the rotation axis of the cam 306 gradually decreases, the rack 308 will slide downward, thereby driving the two gears 307 to rotate synchronously, thereby driving the two spray pipes 301 to swing downward at the same time, thereby adjusting the spray direction of the nozzle 302; the structure is simple, the operation is convenient, the adjustment effect is good, and the rotational motion mode of the tensioning roller 304 can be converted into the swinging motion mode of the spray pipe 301, thereby avoiding the waste of cleaning water and the reduction of the cleaning effect caused by the spray pipe 301 rotating a full circle, and the design is ingenious.

[0044] It should be noted that the transmission assembly 305 may also be other structures, for example, it may be set as a crank rocker mechanism, which only needs to be able to drive the spray pipe 301 to swing.

[0045] refer to Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the transmission assembly 305 further includes an elastic member 309, which is disposed between the rack 308 and the mounting bracket 100 to apply a downward elastic force to the rack 308. For example, the elastic member 309 can be configured as a spring, and the elastic member 309 can extend vertically, the top end of the elastic member 309 can be connected to the mounting bracket 100, and the bottom end of the elastic member 309 can be connected to the rack 308. When the cam 306 pushes the rack 308 to slide up and down, the elastic member 309 is always in a compressed state, and can apply a downward elastic force to the rack 308, and can make the rack 308 pressed against the cam 306, so that the cam 306 drives the rack 308 to slide up and down better.

[0046] It should be noted that the elastic member 309 may also be other structures, for example, an elastic sheet.

[0047] refer to Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the cam 306 is detachably connected to the tension roller 304. In this way, when the belt 200 does not need to be cleaned, the cam 306 can be separated from the tension roller 304. In this way, the tension roller 304 only needs to rotate by itself following the movement of the belt 200, and does not need to drive the transmission assembly 305 and the spray pipe 301 to move, so that the belt 200 moves more smoothly and the driving force required by the driving motor is smaller.

[0048] refer to Figure 3 and Figure 4As shown, in some embodiments of the present invention, a spline groove 311 is provided at one end of the tension roller 304, a threaded hole 312 is provided on the inner end surface of the spline groove 311, an external spline is provided on the cam 306, the external spline is inserted into the spline groove 311, a connecting hole is provided on the cam 306, and a fastening bolt 313 is installed between the connecting hole and the threaded hole 312. In this way, through the cooperation between the external spline and the spline groove 311, and the fastening effect of the fastening bolt 313, the cam 306 can be relatively stably installed on the tension roller 304.

[0049] refer to Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the rack 308 can slide upward to be separated from the cam 306. When the cam 306 needs to be disassembled, the rack 308 is pushed upward to slide the rack 308 to be separated from the cam 306, so that the rack 308 can avoid interfering with the disassembly of the cam 306, making the disassembly of the cam 306 more convenient.

[0050] refer to Figure 3 and Figure 4 As shown, in some embodiments of the present invention, a limiting member 310 is provided between the rack 308 and the mounting frame 100. When the rack 308 slides upward to separate from the cam 306, the limiting member 310 can lock the rack 308 to limit the sliding of the rack 308. For example, the limiting member 310 can be a limiting bolt, the rack 308 can be provided with a first positioning hole 314, and the mounting frame 100 can be provided with a second positioning hole correspondingly. When the rack 308 slides upward to a preset position and separates from the cam 306, the first positioning hole 314 is aligned with the second positioning hole, and then the limiting member 310 is inserted to limit the random sliding of the rack 308, and then when the cam 306 is disassembled, the rack 308 can be prevented from sliding down randomly and interfering with the installation of the cam 306, and after the cam 306 is disassembled, the rack 308 can also be prevented from sliding down randomly and interfering with the tension roller 304.

[0051] It should be noted that the limiting member 310 may also be other suitable structures, for example, it may also be a limiting pin.

[0052] refer to Figures 1 to 4 As shown, in some embodiments of the present invention, the mounting frame 100 is provided with a water collecting box 102, a water outlet pipe is provided at the bottom end of the water collecting box 102, and the tensioning roller 304 and the spray pipe 301 are located in the water collecting box 102. In this way, the water collecting box 102 can not only collect the washing water to avoid the waste of the washing water, but also play a certain blocking role when the nozzle 302 sprays the washing water to prevent the washing water from splashing randomly.

[0053] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
