Description

Technical Field

[0001] This application relates to the field of conveyors, and more particularly, to a turning drum of a belt conveyor. Background Art

[0002] A belt conveyor is a machine that uses friction drive to continuously transport materials. It mainly consists of a frame, a conveyor belt, idlers, drums, a tensioning device, a transmission device, etc. It has the characteristics of strong conveying capacity, long conveying distance, simple structure, easy maintenance, and can be easily programmed and automated. The motor of the belt conveyor drives the driving drum to rotate through the transmission device. Friction is generated between the belt and the driving drum to drive the belt to run. The material to be conveyed is fed onto the belt by a device at one end of the belt and is conveyed to the other end or other specified positions as the belt rotates, completing the conveying process.

[0003] At present, when some roadways need to turn, a turning belt conveyor is required. For example, Chinese Patent Publication No. CN109733805A discloses a two-way transportation turning belt conveyor, in which both the carrying system and the return system can turn to convey materials and are arranged vertically; both the carrying system and the return system include: a belt, a turning drum, a redirecting drum, and a frame; the belt first bypasses the turning drum at a certain angle along its conveying direction and then bypasses the redirecting drum and turns back; both the redirecting drum and the turning drum are installed on the frame.

[0004] Another example is Chinese Patent Publication No. CN203819967U, which discloses a turning device for a belt conveyor. It includes a frame, a redirecting drum, a belt, a spiral drum, a buffer idler, and a drum seat installed on the frame. The spiral drum is installed on the drum seat, and the redirecting drum and the buffer idler are respectively installed on the frame. The belt bypasses the redirecting drum and the spiral drum. The spiral drum includes a slidable adapter plate, an adjustable roller seat, planetary rollers installed on the adjustable roller seat, a shaft, and an expansion sleeve. Both ends of the shaft are installed on the drum seat. The slidable adapter plate is installed on the shaft through the expansion sleeve, and a plurality of adjustable roller seats are evenly installed on the slidable adapter plate through bolts.

[0005] However, when the planetary rollers of the above-mentioned belt conveyor drum are severely damaged after long-term operation and need to be replaced, the entire drum needs to be replaced, and the severely damaged planetary rollers cannot be replaced individually, resulting in a high cost.

[0029] The embodiment of the present application discloses a turning drum of a belt conveyor. Referring to Figures 1-3 , it includes a cylindrical barrel 1. Shafts are coaxially and fixedly arranged at both ends of the barrel 1. A plurality of roller seats 2 are arranged at intervals along the axial and radial directions of the barrel 1. Planetary rollers 21 are arranged on the roller seats 2. Both ends of the planetary rollers 21 are rotationally supported on the inner walls of the roller seats 2. The plurality of roller seats 2 are arranged in multiple rows on the circumferential surface of the barrel 1. A plurality of fixing blocks 3 are arranged at intervals along the radial direction of the barrel 1. The fixing blocks 3 are located between two adjacent rows of roller seats 2. The fixing blocks 3 are connected to the barrel 1 by welding, so the connection is more firm. At the same time, inserting blocks 22 are welded on both opposite sides of the roller seats 2. Inserting grooves 31 are formed on both opposite side walls of the fixing blocks 3. The inserting blocks 22 on both sides of the roller seats 2 are respectively inserted and matched with the inserting grooves 31 on two adjacent fixing blocks 3. And the inserting blocks 22 are triangularly arranged, so that the inserting blocks 22 can be inserted into the inserting grooves 31 more smoothly.

[0030] At the same time, a fixing assembly is arranged between the roller seat 2 and the fixing block 3. Specifically, the fixing assembly includes a cover plate 4 arranged on the fixing block 3, a plurality of screw holes 32 arranged on the fixing block 3 at intervals along the axial length direction of the cylinder body 1, and a plurality of bolts 41 threadedly connected to the cover plate 4 and the screw holes 32. When the plug-in block 22 is inserted into the plug-in groove 31, the cover plate 4 covers the plug-in block 22, and the cover plate 4 fits with the surface of the side of the fixing block 3 away from the cylinder body 1. The operator installs a plurality of roller seats 2 on the cylinder body 1, and respectively inserts the plug-in blocks 22 on both sides of the roller seat 2 into the plug-in grooves 31 on two adjacent fixing blocks 3, and then closes the cover plate 4, and then uses the bolts 41 to fix the cover plate 4 and the fixing block 3 together, so that the roller seat 2 can be fixed. In addition, a pad 221 is welded on the top of the plug-in block 22, and a receiving groove 34 is opened on the fixed block 3. The pad 221 is embedded in the receiving groove 34. The pad 221 can reduce the pressure on the cover plate 4, so that the contact point between the cover plate 4 and the plug-in block 22 is not easy to deform, causing the roller seat 2 to be unreliably fixed.

[0031] In addition, the cover plate 4 is integrally formed with a plurality of extension blocks 45 on one side surface facing the fixed block 3, and the cover plate 4 is provided with a plurality of countersunk grooves 44 on one side surface facing away from the fixed block 3, and the countersunk grooves 44 extend into the extension blocks 45, and the bolts 41 are hexagon socket bolts 41, and the nuts of the bolts 41 are embedded in the countersunk grooves 44, so that the bolts 41 can be flush with the cover plate 4 and not protrude. At the same time, the fixed block 3 is provided with a plurality of receiving grooves 33, and the plurality of extension blocks 45 are respectively plugged into and matched with the plurality of receiving grooves 33, and the plugging of the extension blocks 45 into the receiving grooves 33 not only plays a positioning role, but also can accommodate the extension blocks 45. In addition, both ends of the cover plate 4 are integrally formed with bending portions 42, and the bending portions 42 fit the end faces of the fixed block 3, and screws 43 are threadedly connected between the bending portions 42 and the fixed block 3, and the bending portions 42 can prevent the two ends of the cover plate 4 from being easily lifted.

[0032] The implementation principle of a belt conveyor steering roller in an embodiment of the present application is as follows: an operator installs multiple roller seats 2 on the cylinder body 1, and respectively inserts the plug-in blocks 22 on both sides of the roller seat 2 into the plug-in grooves 31 on two adjacent fixed blocks 3, and then closes the cover plate 4, and then uses bolts 41 to fix the cover plate 4 and the fixed blocks 3 together to fix the roller seat 2. When a single roller seat 2 and a planetary roller 21 need to be replaced, the screws 43 and the multiple bolts 41 are unscrewed, and the single planetary roller 21 can be removed and replaced without replacing the entire roller, thereby reducing costs.

[0033] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
