Description

Technical Field

[0001] This utility model relates to the field of belt elevators, specifically to a tail roller of a belt elevator. Background Technology

[0002] Belt elevators are a common type of continuous conveying equipment, mainly used for vertical or inclined conveying of powdery, granular, and lumpy bulk materials. Buckets are installed on the surface of the belt, and the belt is driven by two rollers.

[0003] The publication number CN215247531U discloses a drum for a bucket elevator, including a central sleeve, and a mounting plate is fixedly connected to the outer wall of the central sleeve. The mounting plate is coaxial with the central sleeve, and the distance from the mounting plate to the two end faces of the central sleeve is the same.

[0004] The aforementioned rollers have the advantage of improving the connection stability between the rollers and the belt, and reducing the probability of damage to the grain. However, some belt conveyors have relatively small housing dimensions. In this case, the two ends of the support plates on the outer side of the rollers will be close to the inner wall of the housing. When adjusting the position of the tail roller using the tensioning mechanisms on both sides, if the adjustment heights on both sides are slightly different, there will be friction between the two ends of the support plates and the inside of the housing when the rollers rotate. This can lead to damage to the inner wall of the housing and the two ends of the support plates, reducing the overall service life of the equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a tail roller for a belt elevator to solve the technical problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A tail roller of a belt elevator includes a cylinder body. Several support plates are fixedly welded to the outside of the cylinder body. Sliding components are installed at both ends of the support plates. Anti-slip components are installed on the outer surface of the support plates. The sliding components include limiting grooves and rollers. The limiting grooves are opened at both ends of the bottom of the support plates. A threaded groove is opened inside the limiting groove. A limiting block is connected to the top of the roller. A connecting hole is opened through the roller and the limiting block. A connecting bolt is connected between the inside of the connecting hole and the threaded groove.

[0008] Preferably, the limiting block and the roller are connected by a bearing, and the bearing at the bottom of the limiting block is installed through the inside of the roller.

[0009] Preferably, the limiting block is hexagonal and the limiting blocks are located inside the limiting groove and are mutually matched.

[0010] Preferably, the connecting bolt is movably disposed within the connecting hole, and the connecting bolt and the threaded groove are connected by a thread.

[0011] Preferably, the anti-slip component includes a fixing plate and a slot, the slot extending through the top of the support plate, a locking strip fixedly installed at the bottom of the fixing plate, and several rubber pads provided at the top of the fixing plate.

[0012] Preferably, both the card strip and the card slot have a "convex" shaped cross-section, and the card strip is inserted into the card slot in a snap-fit ​​configuration.

[0013] Preferably, the rubber pads are fused together with the fixing plate, and a plurality of rubber pads are arranged at equal intervals.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) The tail roller has rollers at both ends of the support plate on the outer side of the cylinder. When the roller rotates in a horizontal state, the rollers at both ends can be in contact with the inner wall of the casing and rotate in the direction of roller rotation. Moreover, since the rollers are in contact with the inner wall of the casing but not pressed tightly, when the tail roller is adjusted using the tensioning mechanisms on both sides, some rollers will press against the inner wall of the casing when the adjustment height is different, making the roller unable to move up and down. This ensures that the adjustment height of the tensioning mechanisms on both sides is consistent, ensuring that the roller is in a horizontal state, and thus avoiding the phenomenon of friction between the two ends of the roller support plate and the inside of the casing. In addition, by setting a sliding component, the limit block is inserted into the limit groove, and the roller and the limit block are connected by a bearing. The connection between the connecting bolt and the screw groove facilitates the installation and removal of the roller.

[0016] 2) The tail roller is equipped with anti-slip components. The clip slides into the slot and increases the friction between the support plate and the belt through the contact between the rubber pad and the belt, thereby improving the transmission efficiency. At the same time, it can provide support space for the material particles and further prevent some materials from being squeezed and damaged when stuck. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] Combination Figures 1-3 A tail roller of a belt elevator includes a cylinder body 1, a plurality of support plates 2 are fixedly welded to the outside of the cylinder body 1, sliding components 3 are installed at both ends of the support plates 2, and anti-slip components 4 are installed on the outer surface of the support plates 2.

[0023] See Figure 2 Furthermore, the sliding component 3 includes a limiting groove 5 and a roller 7. The limiting groove 5 is opened at both ends of the bottom of the support plate 2. A screw groove 6 is opened inside the limiting groove 5. A limiting block 8 is connected and installed on the top of the roller 7. A connecting hole 9 is opened through the roller 7 and the limiting block 8. A connecting bolt 10 is connected between the inside of the connecting hole 9 and the screw groove 6. The cylinder 1 is composed of a date-shaped body and circular plates evenly distributed in the middle and both ends of the date-shaped body. The circular plates at both ends are supported by several lining plates welded at intervals to both sides of the date-shaped body. The design of the date-shaped body allows the incoming material to slide out to both ends. Several support plates 2 are welded on the outside of the circular plates to form the whole roller. The roller is preferably an injection-molded roller.

[0024] The limiting block 8 and the roller 7 are connected by a bearing. The bearing at the bottom of the limiting block 8 is installed inside the roller 7. The roller 7 rotates through the bearing connection, and the side of the roller away from the support plate extends out of the end of the support plate.

[0025] The limiting block 8 is hexagonal and is located inside the limiting groove 5 to match each other. The limiting block 8 is fixed by the snap-fit ​​between the limiting block 8 and the limiting groove 5.

[0026] The connecting bolt 10 is movably installed inside the connecting hole 9, and the connecting bolt 10 is threadedly connected to the screw groove 6. The connecting bolt 10 is used for the installation and removal of the roller 7.

[0027] Specifically, by engaging the limiting block 8 within the corresponding limiting groove 5, and with the connecting bolt 10 passing through the interior of the roller 7 and the limiting block 8, and connecting and fixing it with the screw groove 6, the roller 7 rotates via the bearing connection, preventing the limiting block 8 from loosening. When the roller rotates in a horizontal state, the roller can adhere to the inner wall of the machine housing and rotate in the direction of roller rotation. When adjusting the tail roller using the tensioning mechanisms on both sides, if the adjustment height is different, some rollers will press against the inner wall of the machine housing, preventing the roller from moving up and down. This ensures that the adjustment height of the tensioning mechanisms on both sides is consistent, ensuring that the roller is in a horizontal state, thereby avoiding friction between the ends of the roller support plate and the inside of the machine housing. Example 2

[0028] See Figure 3 Furthermore, based on Embodiment 1, the anti-slip component 4 includes a fixing plate 11 and a slot 12. The slot 12 extends through the top of the support plate 2. A clip 13 is fixedly installed at the bottom of the fixing plate 11, and several rubber pads 14 are provided at the top of the fixing plate 11.

[0029] Both the clip 13 and the slot 12 have a "convex" shaped cross-section. The clip 13 is inserted into the slot 12 in a snap-fit ​​configuration. The clip 13 is used to be inserted laterally into the slot 12. The clip and the slot can be interference fit or clearance fit. When clearance fit, the two ends of the clip are fixed by bolts to facilitate the installation and removal of the fixing plate 11.

[0030] The rubber pads 14 are fused together with the fixing plate 11. Several rubber pads 14 are arranged at equal intervals. The rubber pads 14 are used to increase the friction with the belt.

[0031] Specifically, by inserting the card strip 13 into the inside of the card slot 12 and fixing both ends by bolts, the friction between the card strip 13 and the belt is increased by the rubber pad 14, while providing support space for the material particles and further preventing the material from embedding.

[0032] In actual operation, several support plates 2 are welded around the outer surface of the cylinder 1. The inside of the cylinder 1 is shaped like a date pit. The support plates 2 are used to support the belt, so that the material enters through the gap between every two support plates 2 and is discharged to both sides through the inside of the cylinder 1, reducing the material getting stuck.

[0033] When installing roller 7, the limiting block 8 is engaged in the corresponding limiting groove 5, and the connecting bolt 10 passes through the inside of roller 7 and limiting block 8, and is connected and fixed with the screw groove 6. This allows roller 7 to rotate through the bearing connection and prevents the connecting bolt 10 from loosening due to the rotation of limiting block 8. During the rotation of cylinder 1, the rollers at both ends of support plate 2 will be in contact with and rotate against the inner wall of the machine casing. The rollers ensure that the roller is in a horizontal state when adjusting up and down, and also prevent the two ends of the roller support plate from rubbing against the inside of the machine casing, which could cause damage to the inner wall of the machine casing and the two ends of the support plate.

[0034] When anti-slip is applied, the clip 13 is inserted into the slot 12 and fixed by bolts. The belt contacts the rubber pad 14, and the rubber pad 14 increases the friction between the belt and the belt. At the same time, it can provide support space for the material particles and further prevent some materials from being squeezed and damaged when stuck.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
