DETAILED DESCRIPTION

[0015] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] See also Figure 1-6 A conveyor belt cleaner comprises a cross beam 1 and a cross beam 2. The bottom surfaces of the cross beam 1 and the cross beam 2 are provided with a plurality of equally spaced square rods 3. Both ends of each square rod 3 are integrally connected with a shaft sleeve 4. The shaft sleeve 4 is provided with a shaft hole 13. The shaft hole 13 is a polygonal hole. One end of the square rod 3 is integrally connected with a limit plate 5 at a connection position corresponding to the shaft sleeve 4. The other end of the square rod 3 is bolted with a stop plate 6 at a connection position corresponding to the shaft sleeve. A cleaning cloth cover 7 is sleeved on the square rod 3 between the stop plate 6 and the limit plate 5. The lower surfaces of the cross beam 1 and the cross beam 2 are bolted with a shaft seat 1 8 at the shaft sleeve 4 positions at both ends of the square rod 3. The shaft sleeve 4 is sleeved on the bearing of the shaft seat 1 8 at the corresponding position to form a sleeve connection and fixation.

[0017] In this embodiment, the square bars 3 are coaxially connected, and the linkage rod 12 is inserted into the shaft hole 13 to form a transmission fixation with the shaft sleeve 4 and the square bars 3. The connection between the front two square bars 3 and the connection between the rear two square bars 3 are coaxially connected to the sprocket wheel 9, and the upper sprocket wheel 10 is provided above the cross beam 1 and the cross beam 2 at the position corresponding to the lower sprocket wheel 9. A transmission chain 11 is wound between the upper sprocket wheel 10 and the lower sprocket wheel 9. A transmission rod 14 is passed through the upper sprocket wheel 10 above the cross beam 1 and the cross beam 2. A shaft seat 2 15 is bolted to the cross beam 1 and the cross beam 2 at the position corresponding to the transmission rod 14. The transmission rod 14 is sleeved on the bearing of the shaft seat 2 15 to form a sleeve connection fixation. A motor 16 is bolted to the top of the cross beam 1 and the cross beam 2 at the position corresponding to one end of the transmission rod 14. The shaft of the motor 16 is connected to the transmission rod 14 at the corresponding position by a pin key. A support frame 17 is welded and installed at both ends of the cross beam 1 and the cross beam 2, and an upper fixing plate 18 is welded and installed at the bottom of the support frame 17. A lower clamping plate 19 is provided directly below the upper fixing plate 18, and multiple fastening bolts 20 are passed between the upper fixing plate 18 and the lower clamping plate 19.

[0018] Before use, loosen the fastening bolts 20, then place the upper fixing plate 18 above the belt conveyor frame 29, push the lower clamping plate 19 to the bottom of the frame at the corresponding position, and then tighten the fastening bolts 20 to clamp and fix it, so that the cleaning cloth cover 7 can be attached to the surface of the conveyor belt 30. According to the different specifications of the conveyor belt, the cross beam 1 and the cross beam 2 are also preset with different models of corresponding specifications. When in use, turn on the motor 16, and the motor 16 rotates through the transmission relationship of the transmission rod 14-upper sprocket 10-chain 11-lower sprocket 9-linkage rod 12-square rod 3 to drive the cleaning cloth cover 7 to rotate. The rotation direction of the cleaning cloth cover 7 is opposite to the rotation direction of the conveyor belt 30, and the rotation speed is faster than the rotation speed of the conveyor belt 30, so that the cleaning cloth cover 7 attached to the surface of the conveyor belt 30 cleans its surface through rotation.

[0019] In this embodiment, a cross beam three 21 is provided at a position directly below the cross beam one 1 and the cross beam two 2. The two ends of the cross beam three 21 are fixed to the support frame one 17 at the corresponding position by bolts. A plurality of guide rollers 22 are provided on the top surface of the cross beam three 21. Both ends of each guide roller 22 are provided with an axle seat three 23. The two ends of the guide roller 22 are sleeved into the bearings of the axle seat three 23 at the corresponding position to form a sleeve connection. The axle seat three 23 is fixed to the top surface of the cross beam three 21 by bolts. A gap is reserved between the guide roller 22 and the cleaning cloth cover 7 for the conveyor belt 30 to pass through.

[0020] During installation, the conveyor belt 30 passes through the gap between the guide roller 22 and the cleaning cloth cover 7, and the guide roller 22 supports the conveyor belt 30 from the bottom, thereby ensuring that the cleaning cloth cover 7 can stably and reliably contact the surface of the conveyor belt 30, thereby ensuring that there is sufficient contact force for cleaning during rotation.

[0021] In this embodiment, the cleaning cloth covers 7 on the first cross beam 1 and the second cross beam 2 are staggered and the paths at both ends are partially overlapped, and the width of the overlapped path is not less than 2 centimeters.

[0022] There are inevitably gaps between adjacent cleaning cloth covers 7. By staggering and overlapping the paths, the gaps between them can be covered to ensure a cleansing effect without dead angles on the surface of the conveyor belt 30.

[0023] In this embodiment, a brush roller 24 is provided on the front side of the cross beam 1 in the approaching direction of the conveyor belt 30, and support frames 25 are provided at both ends of the brush roller 24. The bottom of the support frame 25 is also provided with an upper fixing plate 18, a lower clamping plate 19 and a fastening bolt 20 of the same structure, and an axle seat 4 26 is boltedly installed on the support frame 25 at the two end positions corresponding to the brush roller 24. The two ends of the brush roller 24 are sleeved on the bearings of the axle seat 4 26 to form a sleeve connection, and a motor frame 28 is welded and installed on the outer side of the support frame 25 at one end of the brush roller 24. A motor 27 is bolted on the motor frame 28, and the shaft of the motor 27 is connected to the brush roller 24 at the corresponding position through a coupling transmission, and the bristles on the brush roller 24 are against the surface of the conveyor belt 30.

[0024] After the support frame 17 is installed, the support frame 25 can be installed. In this way, when cleaning, the motor 27 is used to drive the brush roller 24 to rotate, so that the bristles on the surface of the brush roller 24 can be used to clean the surface of the conveyor belt 30 in advance, which is suitable for cleaning residual materials or foreign objects that are simply attached to the surface, so as to avoid excessive contamination of the cleaning cloth cover 7, which leads to an increase in the frequency of replacement and the resulting increase in cost. The rotation direction of the brush roller 24 is the same as that of the cleaning cloth cover 7, which is opposite to the rotation direction of the conveyor belt 30.

[0025] In this embodiment, the brush roller 24 is disposed obliquely, and the oblique angle between the brush roller 24 and the conveyor belt 30 is 110°-120°.

[0026] The oblique angle setting allows the brush roller 24 to push the cleaned material to the outside of the conveyor belt 30 through the mutual friction resistance with the cleaned material when rotating for cleaning, thereby making it escape from the conveyor belt 30, avoiding it from being retained on the surface of the conveyor belt 30 and affecting the subsequent cleaning of the brush roller 24.

[0027] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
