[0021] In a possible design, a plurality of longitudinal supporting plates are fixedly connected between the sides of the two side edge plates, a plurality of transverse supporting plates are fixedly connected to the top of the longitudinal supporting plates, a plurality of fixed shafts are fixedly connected between the two side edge plates, a plurality of rotating supporting wheels are rotatably sleeved on the outer wall of the fixed shaft, and the rotating supporting wheels and the transverse supporting plates are in abutment with the inner surface of the conveying belt.

[0022] In the application, when in use, the material falls from the top end of the conveying belt, the driving motor is started, the output shaft of the driving motor drives one of the rotating rollers to rotate through the second synchronous wheel and the second synchronous belt, the rotating roller drives a plurality of pulleys to rotate, thereby the conveying belt can be conveyed forward, the conveying belt can convey the material above forward, and the function of material conveying is achieved.

[0023] When the conveying belt is conveying, the plurality of auxiliary supporting legs can support the conveying belt, the plurality of rotating supporting wheels are in abutment with the inner surface of the conveying belt, the stability of the two auxiliary supporting legs is guaranteed by the setting of the reinforcing plate, the height of the auxiliary supporting leg can be adjusted through the rotating adjusting bolt, and thereby the application range of the device can be improved.

[0024] When the conveying belt is loose, the position of the rotating roller can be adjusted to realize the tensioning operation, the position of the side edge rectangular plate relative to the lug plate can be adjusted by unscrewing the first limiting nut, the limiting rod can slide in the slot-shaped hole, and thereby the position of the rotating roller on one side can be adjusted, and the conveying belt can be tensioned to ensure the normal transportation of the material.

[0025] When the material is transported, a small amount of dust or impurities will be left on the surface of the conveying belt. When the driving motor starts, the output shaft of the driving motor drives the first transmission shaft to rotate through the first synchronous wheel and the first synchronous belt. The first transmission shaft drives one of the first driving shafts to rotate, and the first driving shaft drives the corresponding eccentric plate to rotate. The eccentric plate continuously pushes the support horizontal plate upwards, and the support horizontal plate drives the cutter to move upwards to cut the impurities on the surface of the conveying belt, facilitating subsequent cleaning. When the eccentric plate no longer abuts against the support horizontal plate, the elastic force of the spring can drive the support horizontal plate to reset;

[0026] Meanwhile, the first driving shaft can drive the second driven shaft to rotate through the third synchronous wheel and the third synchronous belt. The second driven shaft drives the drum brush to rotate, which sweeps the outer surface of the conveying belt. The second driven shaft drives the first bevel gear to rotate, which drives the second bevel gear to rotate. The second bevel gear drives the second driving shaft to rotate, which drives multiple second transmission shafts to rotate through the meshing of the driving gear, the second bevel gear and the connecting gear. The second transmission shafts drive the circular brushes at both ends to rotate, which sweeps the outer surface of the conveying belt from the side again to ensure the cleaning intensity.

[0027] When one of the second transmission shafts rotates, it can drive the rotating rod to rotate, which drives the half gear to rotate. The half gear continuously meshes with the toothed strips on the upper and lower sides, thereby continuously driving the elliptical ring to move back and forth in the horizontal direction. The elliptical ring drives the strip-shaped brush to move back and forth in the horizontal direction, thereby cleaning the dust remaining on the bottom of the conveying belt again to improve the cleaning effect.

[0028] After cleaning the outer surface of the conveying belt, the infrared emitter can also emit infrared rays, which are received by the infrared receiver on the opposite side. By monitoring the height of the inner surface of the conveying belt, the tension of the conveying belt can be understood. By monitoring the height of the outer surface of the conveying belt, the dust residue on the surface of the conveying belt can be monitored. If there is too much dust residue, the micro motor can be started to drive the cleaning assembly on the other side to clean again, thereby ensuring the cleaning effect of the conveying belt for normal transportation.

[0029] After the dust is swept out, it falls into the interior of the U-shaped plate for collection. The dust slides down the surface of the inclined plate into the interior of the dust discharge hole and enters the interior of the dust collection box for final collection. When the dust inside the dust collection box needs to be treated, the side pull plates on both sides can be moved away from each other, which drives the inclined plate to move horizontally. When the inclined plate no longer supports the L-shaped block, the L-shaped block can be removed from the inside of the gap. Thus, the dust collection box and the L-shaped block can be removed from below the U-shaped plate for easy cleaning of the internal dust.

[0030] When the internal components of the device need to be repaired and replaced, the two side pull plates can be continuously moved, the side pull plates drive the inclined plate to continue to move, at this time the side pull plates drive the two positioning rods from the inside of the positioning groove, thereby the braking state of the rotating baffle can be released, and then the rotating baffle can be opened from one side, after opening, the internal components can be conveniently taken out by the staff for replacement and repair.

[0031] Beneficial effects:

[0032] The application drives the rotating roller and the belt pulley by the driving motor, realizes continuous and stable conveying of the conveying belt, and improves the efficiency of material conveying.

[0033] By adjusting the assembly, the distance between the side rectangular plate and the side plate can be adjusted, and the position of the rotating roller can be adjusted, so that the tensioning operation of the conveying belt is realized, and the stability and reliability of the conveying process are ensured.

[0034] The design of the lifting assembly makes the height of the side plate adjustable, which meets the needs of different scenes and enhances the application range of the device.

[0035] The auxiliary leg slides in the main leg and is stable through the reinforcing plate, and the height can be accurately adjusted through the adjusting bolt.

[0036] The cleaning assembly cooperates with the eccentric plate, cutter, drum brush, circular brush and strip brush to clean the surface of the conveying belt in multiple layers and all directions, effectively removing dust and impurities.

[0037] Especially the reciprocating movement of the strip brush in the horizontal direction further improves the cleaning effect and ensures the cleanliness of the conveying belt.

[0038] The tensioning degree and surface dust residue degree of the conveying belt are monitored by the infrared emitter and the infrared receiver, realizing intelligent monitoring.

[0039] When the dust residue is too much, the micro motor can be automatically started to drive the cleaning assembly on the other side for re-cleaning, ensuring the continuous cleaning of the conveying belt.

[0040] The collection assembly is reasonably designed, which collects dust through the inclined plate and dust collection box, and is convenient to clean.

[0041] The design of the side pull plate and the rotating baffle makes the repair and replacement of the internal components of the device simple and fast. BRIEF DESCRIPTION OF DRAWINGS

The letting holes 41 are used in cooperation with the L-shaped blocks 42. Symmetrically arranged two inclined plates 38 are slidingly connected to the inner wall of the bottom of the U-shaped plate 3. The inclined plates 38 are used for supporting the L-shaped blocks 42. A side edge pull plate 29 is fixedly connected to one side of the inclined plate 38. Two symmetrically arranged rectangular holes 35 are formed in one side of the U-shaped plate 3. A rotating baffle 34 is hingedly connected to the inside of the rectangular hole 35. Two symmetrically arranged positioning grooves 40 are formed in one side of the rotating baffle 34. Two symmetrically arranged positioning rods 39 are fixedly connected to one side of the side edge pull plate 29. The positioning rods 39 are clamped with the positioning grooves 40. First rectangular blocks 31 are fixedly connected to the top of both sides of the U-shaped plate 3. An infrared receiver 33 and an infrared emitter 32 are arranged on the sides of the two first rectangular blocks 31 which are close to each other. After the dust is swept out, it falls into the inside of the U-shaped plate 3 for collection. The dust slides along the surface of the inclined plate 38 to the inside of the dust discharging hole 37 and then enters the inside of the dust collecting box 30 for final collection. When it is necessary to process the dust in the inside of the dust collecting box 30, the side edge pull plates 29 on both sides can be moved away from each other. The side edge pull plate 29 drives the inclined plate 38 to move horizontally. When the inclined plate 38 no longer supports the L-shaped block 42, the L-shaped block 42 can be removed from the inside of the letting hole 41. Then the dust collecting box 30 and the L-shaped block 42 can be removed from the bottom of the U-shaped plate 3, so that the inside dust can be conveniently cleaned. When it is necessary to overhaul and replace the parts in the inside of the device, the two side edge pull plates 29 can be continuously moved. The side edge pull plate 29 drives the inclined plate 38 to continuously move. At this time, the side edge pull plate 29 drives the two positioning rods 39 to be removed from the inside of the positioning groove 40. Then the state of the rotating baffle 34 being braked can be released. Then the rotating baffle 34 can be opened from one side. After being opened, the inside parts can be conveniently taken out by the staff for replacement and overhaul.
