Description

Technical Field

[0001] This utility model relates to the field of belt cleaning technology for belt conveyors, and in particular to a belt conveyor cleaning device and a belt conveyor. Background Technology

[0002] A belt conveyor, also known as a rubber belt conveyor, is a type of continuously operating transportation equipment that uses a conveyor belt as both a traction and load-bearing component. The traction force is generated by the frictional resistance between the tensioned conveyor belt and the drive drum. During operation, fine coal dust, mud, and powdery materials can adhere to the working surface of the belt.

[0003] In the prior art, in order to clean the residue on the belt, a belt cleaning device disclosed in patent CN107161646A is used, which includes: a drive shaft installed on the belt frame and fitted with a drive roller; a lower shaft parallel to the drive shaft is movably supported on the belt frame directly below the drive shaft; a plurality of scraper plates are arranged circumferentially on the shaft body of the lower shaft; a small sprocket is fitted on one side of the shaft end of the lower shaft; a large sprocket is fitted on the shaft end of the drive shaft on the same side as the small sprocket; and a transmission chain is wound between the large sprocket and the small sprocket.

[0004] In the above scheme, several scraper blades are installed on the shaft of the lower rotating shaft. After long-term use, the scraper blades are prone to wear, which affects the cleaning effect of residual materials. Utility Model Content

[0005] In response to the problem that scraper blades are prone to wear after prolonged use, affecting the cleaning effect of residual materials, this utility model provides a belt conveyor cleaning device and belt conveyor.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0007] A belt conveyor cleaning device includes a first bearing housing, within which a drive roller neck is rotatably mounted. The drive roller neck is connected to a cleaning roller via a transmission assembly, which is housed within a mounting box. The mounting box is positioned between the first bearing housing and the drive roller body. The drive roller neck passes through the mounting box and connects to the transmission assembly. The end of the transmission assembly furthest from the drive roller is connected to the cleaning roller neck. A rotation drive assembly is connected to the outer wall of the mounting box, driving the mounting box to rotate around the drive roller neck. The rotation drive assembly facilitates the rotation of the mounting box around the drive roller neck after the cleaning roller wears down, thereby adjusting the distance between the cleaning roller and the belt conveyor, ensuring proper cleaning of the belt conveyor by the cleaning roller.

[0008] Preferably, the rotation drive assembly includes a steel wire rope; one end of the steel wire rope is connected to the housing of the mounting box; the other end is connected to a turnbuckle. By adjusting the length of the turnbuckle, the steel wire rope drives the mounting box to rotate, thereby adjusting the distance between the cleaning roller and the conveyor belt.

[0009] Preferably, one end of the wire rope is connected to a connecting rod; the end of the connecting rod away from the wire rope is hinged to a mounting box. The connecting rod reduces wear on the wire rope from the cleaning roller, extending the service life of the wire rope.

[0010] Preferably, the mounting box is shaped like a rectangular shell; a hinge rod is fixedly mounted on the outer wall of the mounting box at the end away from the drive roller; the connecting rod is hinged to the hinge rod via a pin. This facilitates the hinged connection between the connecting rod and the mounting box.

[0011] Preferably, the transmission assembly includes a drive sprocket keyed to the neck of the drive roller; the drive sprocket is connected to a driven sprocket via a chain; and the driven sprocket is keyed to the neck of the cleaning roller.

[0012] Preferably, a second bearing seat is installed on the inner wall of the mounting box to mate with the drive roller; a third bearing seat is installed on the inner wall of the mounting box to mate with the cleaning roller. This ensures the stability of the drive roller and the cleaning roller on the mounting box and reduces wear.

[0013] Preferably, a fixing pin is provided at the neck of the cleaning roller after it passes through the mounting box.

[0014] A belt conveyor includes a drum with a belt wound around it. A tension roller is provided on the outer wall of the return section of the belt. The belt conveyor also includes the aforementioned belt conveyor cleaning device. The belt is disposed between the drive roller and the cleaning roller. The drive roller abuts against the inner wall of the belt and is disposed between the tension roller and the drum. The end of the rotation drive assembly away from the mounting box is connected to the ground.

[0015] As can be seen from the above technical solutions, the advantages of this utility model include: by setting the rotation drive component, it is convenient to drive the mounting box to rotate around the neck of the active roller after the cleaning roller wears out, thereby adjusting the distance between the cleaning roller and the belt of the conveyor belt, and ensuring that the cleaning roller cleans the belt of the conveyor belt.

Detailed Implementation

[0022] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0023] Example 1

[0024] like Figure 1 and Figure 2 As shown, a belt conveyor cleaning device includes a first bearing housing 1, within which the neck of a drive roller 2 is rotatably disposed. The neck of the drive roller 2 is connected to a cleaning roller 3 via a transmission assembly, which is disposed within a mounting box 4. The mounting box 4 is disposed between the first bearing housing 1 and the body of the drive roller 2. The neck of the drive roller 2 passes through the mounting box 4 and is connected to the transmission assembly. The end of the transmission assembly away from the drive roller 2 is connected to the neck of the cleaning roller 3. A rotation drive assembly is connected to the outer wall of the mounting box 4. The rotation drive assembly is used to adjust the distance between the cleaning roller 3 and the belt of the belt conveyor.

[0025] In use, one end of the rotary drive assembly is connected to the ground, and the angle between the center line of the rotary drive assembly and the conveyor belt is set to an acute angle. The rotary drive assembly drives the mounting box 4 to rotate around the neck of the drive roller 2, thereby ensuring that the bristles or scraper of the cleaning roller 3 on the mounting box 4 contacts the conveyor belt 15. The belt 15 is placed between the drive roller 2 and the cleaning roller 3, with the drive roller 2 contacting the belt 15. The belt 15 drives the drive roller 2 to rotate, which in turn drives the cleaning roller 3 to rotate through the transmission assembly. The bristles or scraper of the cleaning roller 3 clean the residual material on the belt 15. After the cleaning roller 3 wears down, the rotary drive assembly drives the mounting box 4 to rotate around the neck of the drive roller 2, thereby adjusting the distance between the cleaning roller 3 and the conveyor belt 15 to ensure that the cleaning roller 3 cleans the conveyor belt 15.

[0026] In the above configuration, the rotation drive assembly includes a steel wire rope 5; one end of the steel wire rope 5 is connected to the housing of the mounting box 4; the other end is connected to a turnbuckle 6. By adjusting the length of the turnbuckle 6, the mounting box 4 is driven to rotate around the neck of the drive roller 2, thereby adjusting the distance between the cleaning roller 3 and the conveyor belt 15. In use, the center lines of the steel wire rope 5 and the turnbuckle 6 are set at an acute angle with the belt 15, and the steel wire rope 5 is not taut. The brush or scraper of the cleaning roller 3 contacts the belt 15. After the brush or scraper of the cleaning roller 3 wears down, rotating the turnbuckle 6 causes the steel wire rope 5 to tighten, driving the mounting box 4 to rotate around the neck of the drive roller 2, reducing the distance between the cleaning roller 3 and the conveyor belt 15, and ensuring that the cleaning roller 3 cleans the conveyor belt 15.

[0027] In order to reduce the wear of the cleaning roller 3 on the wire rope 5 and extend the service life of the wire rope 5, a connecting rod 7 is connected to one end of the wire rope 5; the end of the connecting rod 7 away from the wire rope 5 is hinged to the mounting box 4.

[0028] The mounting box 4 is generally rectangular in shape; a hinge rod 401 is fixedly mounted on the outer wall of the mounting box 4 at the end away from the drive roller 2; the connecting rod 7 is hinged to the hinge rod 401 via a pin. This facilitates the hinged connection between the connecting rod 7 and the mounting box 4.

[0029] In other alternative embodiments, the rotation drive assembly includes an electric push rod, the piston rod of which is hinged to the hinge rod 401, and the cylinder of the electric push rod is hinged to the ground. The electric push rod drives the mounting box 4 to rotate around the neck of the drive roller 2, thereby reducing the distance between the cleaning roller 3 and the conveyor belt 15 and ensuring that the cleaning roller 3 cleans the conveyor belt 15.

[0030] like Figure 3As shown, the transmission assembly includes a drive sprocket 8 keyed to the neck of the drive roller 2; the drive sprocket 8 is connected to a driven sprocket 10 via a chain 9; the driven sprocket 10 is keyed to the neck of the cleaning roller 3. A second bearing seat 11 is mounted on the inner wall of the mounting box 4 to fit the neck of the drive roller 2; a third bearing seat 12 is mounted on the inner wall of the mounting box 4 to fit the neck of the cleaning roller 3. This ensures the stability of the drive roller 2 and the cleaning roller 3 on the mounting box 4 and reduces wear. A fixing pin 13 is provided after the neck of the cleaning roller 3 passes through the mounting box 4.

[0031] In other alternative embodiments, the driving sprocket 8 is replaced by a driving pulley, the driven sprocket 10 is replaced by a driven pulley, and the chain 9 is replaced by a timing belt.

[0032] Example 2

[0033] like Figure 4 As shown, a belt conveyor includes a drum 14 with a belt 15 wound around it. A tension roller 16 is provided on the outer wall of the return section of the belt 15. It also includes a belt conveyor cleaning device as described in Embodiment 1. The belt 15 is positioned between a drive roller 2 and a cleaning roller 3. The drive roller 2 abuts against the inner wall of the belt 15 and is positioned between the tension roller 16 and the drum 14. The end of an adjusting assembly away from the mounting box 4 is connected to the ground. A first bearing seat 1 is fixed to a support rod (not shown). One end of a turnbuckle 6 is fixed to the ground, and the other end of the turnbuckle 6 is connected to a steel wire rope 6. The end of the steel wire rope 5 away from the turnbuckle 6 is connected to a connecting rod 7.

[0034] In use, the tension of the belt 15 is adjusted using the tension roller 16 to ensure that the belt 15 is in contact with the drive roller 2. At this time, the turnbuckle 6, wire rope 5, and connecting rod 7 are not connected in a straight line, and the bristles or scraper of the cleaning roller 3 are in contact with the belt 15. The roller 14 drives the belt 15 to rotate, which in turn drives the drive roller 2 to rotate, which in turn drives the drive sprocket 8 on the roller neck of the drive roller 2 to rotate, which in turn drives the driven sprocket 10 to rotate via the chain 9, thereby driving the cleaning roller 3 to rotate. The cleaning roller 3 uses the bristles or scraper to clean the material remaining on the belt 15.

[0035] After a period of use, when the bristles or scraper of the cleaning roller 3 wear down and can no longer contact the belt 15, the turnbuckle 6 is rotated to reduce its length, causing the wire rope 5 to tighten. This, in turn, drives the connecting rod 7 to move. At this point, the turnbuckle 6, wire rope 5, and connecting rod 7 are connected in a straight line. The connecting rod 7 drives the mounting box 4 to rotate around the neck of the drive roller 2 by a certain arc, reducing the distance between the bristles or scraper of the cleaning roller 3 and the belt 15. This allows the bristles or scraper of the cleaning roller 3 to contact the belt 15 again, cleaning the residual material on the belt 15. This extends the service life of the cleaning roller 3, reduces the frequency of replacement, and lowers maintenance workload. Furthermore, no additional power is required. The friction between the belt 15 and the drive roller 2 drives the cleaning roller 3 to rotate and clean the belt 15. The tangential direction of the rotating cleaning roller 3 is opposite to the return direction of the belt 15, improving the cleaning effect on the residue on the belt 15.

[0036] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
