Description

Technical Field

[0001] This utility model belongs to the field of conveyor technology, specifically relating to a small adjustable belt conveyor. Background Technology

[0002] Belt conveyors are a common type of mechanical equipment used in industrial production for the turnover or transfer of goods. The appropriate type of conveyor can be selected based on the application scenario. Currently, most adjustable belt conveyors on the market primarily rely on adjustable lifting legs for tilt angle adjustment. Some belt conveyors that combine platforms and ramps have the adjustable lifting legs installed separately at the bottom of the platform and ramp frames for support. During adjustment, the platform portion is limited to height adjustment and cannot have its tilt angle adjusted independently. Furthermore, these belt conveyors that integrate ramps and platforms lack length extension adjustment functionality. Consumers often have to customize them according to the actual needs of the site, and cannot effectively adapt to changes in site layout, thus limiting the use of belt conveyors.

[0003] Therefore, we propose a small adjustable belt conveyor. Utility Model Content

[0004] The purpose of this invention is to provide a small adjustable belt conveyor to solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A small adjustable belt conveyor specifically includes a platform conveyor section, an inclined conveyor section, and a conveyor belt. The platform conveyor section is adjustablely mounted at the end of the inclined conveyor section via an arbitrary angle adjustment plate and bolts. The arbitrary angle adjustment plate is a conventional metal connector among hardware accessories. One end of the plate is square and is mounted at the end of the inclined conveyor section. The other end of the plate is arc-shaped and has two concentric arc-shaped grooves for mounting the platform conveyor section with bolts, thus making the angle of the platform conveyor section adjustable.

[0007] Furthermore, to enable the belt conveyor to adjust its length, we designed the inclined conveyor section into two adjustable structures that interlock. Specifically, the inclined conveyor section is divided into a left frame and a right frame, which are slidably interlocked. To make the length adjustment of the entire inclined conveyor section more convenient, a top frame is installed at the bottom of both the left and right frames, and an electric push-pull cylinder that controls the extension and retraction of the left and right frames is hinged between the two top frames.

[0008] Furthermore, to ensure the adaptability of the belt conveyor in different application scenarios, at the bottom of the left and right frames of the inclined conveyor section, at opposite ends, there is a set of adjustable lifting legs connected by bolts to an arc-shaped angle adjustment bracket plate. The bottoms of the two sets of adjustable lifting legs are connected by two sets of telescopic beams. The adjustable lifting legs are the conventional H-type lifting legs used in small adjustable belt conveyors. The two sets of H-type lifting legs, together with the two sets of telescopic beams, ensure that the entire belt conveyor frame stands firmly on the ground. In addition, to facilitate the movement of the belt conveyor, a caster wheel with brakes is installed at the bottom of each set of adjustable lifting legs.

[0009] Furthermore, to achieve the length-short extension design of the belt conveyor, the left frame includes two parallel left beams, and an extension beam is installed at the end of each of the two left beams near the right frame. A follower roller is rotatably installed on the opposite side of the front end of the two extension beams. A left belt support plate is horizontally fixed between the two left beams. Several left connecting plates are integrally formed at equal intervals from left to right at the end of the left belt support plate near the right frame. When the sub-frame is angled, in order to make the transition of the conveyor belt between the inclined conveyor section and the platform conveyor section smoother and reduce the friction of the conveyor belt, a transition roller is rotatably installed at the end of the two left beams away from the right frame.

[0010] The right frame includes two hollow right beams that are opposite to the left beam in the left frame. The two extension beams are slidably inserted into the right beams on their respective sides. A clearance groove is provided on the opposite side of the two right beams in the right frame along the sliding direction of the extension beams to facilitate the displacement of the follower rollers as the extension beams move. To make the displacement between the left and right frames smoother, several rollers are hinged at equal intervals at the top and bottom of the extension beams. The rollers are preferably silent rubber wheels.

[0011] Furthermore, to ensure better connection and cooperation between the right frame and the left frame, a right belt support plate is horizontally fixed between the two right beams. Several right connecting plates are integrally formed at the gaps between adjacent left connecting plates on the right belt support plate near the left frame, from left to right. The right belt support plate, left belt support plate, right connecting plate, and left connecting plate are all on the same plane. The several left and right connecting plates are alternately slidably inserted. When the left and right frames are closed, the gaps between the left and right connecting plates fill and close, forming a complete belt support panel. To improve the compressive strength of the left and right connecting plates, crossbeams are fixed at opposite ends of the two left beams and two right beams to support the right and left connecting plates respectively. The bottoms of the left and right connecting plates slide against the surface of the corresponding crossbeams.

[0012] Furthermore, a driven roller is rotatably mounted between the ends of the two right beams away from the left frame, while a secondary roller is rotatably mounted at the bottom of the other ends of the two right beams via a bracket. The height of the secondary roller is lower than that of the driven roller.

[0013] Furthermore, the platform conveying unit includes a sub-frame hinged to the left frame. The sub-frame includes two sub-beams rotatably mounted at the ends of the two left beams via arbitrary angle adjustment plates, and rollers rotatably mounted at the bottom of the two arbitrary angle adjustment plates. A drive roller is rotatably mounted at the end of the two sub-beams away from the left beam. One end of the drive roller is connected to a drive motor assembly mounted at the bottom of one of the sub-beams. A sub-belt support plate is installed between the two sub-beams. The drive motor assembly includes a drive motor and gears mounted on the output shaft of the drive motor and at the end of the drive roller. The two gears are connected by a chain drive.

[0014] Furthermore, to facilitate the telescopic adjustment between the left and right frames, the frame at the bottom supporting the conveyor also needs to be telescopic. Specifically, the telescopic beam mainly consists of a plug beam and a sleeve beam, which are slidably plugged together. The plug beam and sleeve beam are fixed to the bottom of two sets of adjustable lifting legs. The sleeve beam has a locking bolt on the outer side of its tube end. During length adjustment, the locking bolt needs to be loosened in advance to allow the plug beam and sleeve beam to slide freely. After the length adjustment between the left and right frames is completed, the locking bolt can be tightened again.

[0015] To control the operation of the belt conveyor, a starter controller for controlling the drive motor assembly is installed on the outside of one of the adjustable lifting outriggers.

[0016] To ensure stable belt conveying while maintaining its extendable and adjustable function, the conveyor belt sequentially passes through the drive roller, transition roller, driven roller, auxiliary roller, follower roller, idler roller, and drive roller to form a closed loop. During the extension and retraction adjustment between the left and right frames, the follower roller moves left and right along with the extension beam. The distance between the follower roller and the auxiliary roller is the total extension and retraction distance of the conveyor. If the conveyor belt is missing or extra during the extension or retraction adjustment, it is automatically compensated by the movement of the follower roller, thereby ensuring the tension between the conveyor belt and the drive roller and driven roller.

[0017] Beneficial effects:

[0018] The belt conveyor described in this utility model integrates an inclined plane and a platform. The platform conveying section and the inclined conveying section are hinged together using an adjustable plate at any angle. Adjustable lifting legs are installed at the bottom of the inclined conveying section for support. Combined with the telescopic design of the inclined conveying section, this conveyor has more flexible angle and length adjustment functions compared to traditional platform inclined conveyors. The height, inclination, and length of the platform conveying section and the inclined conveying section can be flexibly adjusted according to actual usage needs. Moreover, the design of the left and right belt pallets on the inclined conveying section ensures that the left and right belt pallets are always on the same plane during the length adjustment process. Compared with the height design of the pallet extension connection position in traditional telescopic belt conveyors, there is no inclined transition zone, resulting in smoother material conveying. Furthermore, this telescopic structure design is relatively simpler than the telescopic structure design of traditional conveyors. Attached Figure Description

[0024] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0025] Example:

[0026] like Figure 1-4 As shown, this embodiment provides a small adjustable belt conveyor, specifically including a platform conveyor section, an inclined conveyor section, and a conveyor belt 4. The platform conveyor section is adjustablely mounted at the end of the inclined conveyor section via an arbitrary angle adjustment plate 7 and bolts. The arbitrary angle adjustment plate 7 is a conventional metal connector among hardware accessories. One end of the plate is square and is mounted at the end of the inclined conveyor section. The other end of the plate is arc-shaped and has two concentric arc-shaped grooves for mounting the platform conveyor section with bolts, making the angle of the platform conveyor section adjustable.

[0027] To enable length adjustment of the belt conveyor, we designed the inclined conveyor section into two adjustable structures that interlock. Specifically, the inclined conveyor section is divided into two parts: a left frame 1 and a right frame 2. The left frame 1 and the right frame 2 are connected by a sliding interlocking joint. To make the length adjustment of the entire inclined conveyor section more convenient, a top frame 5 is installed at the bottom of both the left frame 1 and the right frame 2. An electric push-pull cylinder 6 that controls the extension and retraction of the left frame 1 and the right frame 2 is hinged between the two top frames 5.

[0028] To ensure the adaptability of the belt conveyor in different application scenarios, at the bottom of the left frame 1 and the right frame 2 in the inclined conveyor section, at the ends far apart from each other, there is a set of adjustable lifting legs 9 connected by bolts to the arc-shaped angle adjustment bracket plate 8. The bottoms of the two sets of adjustable lifting legs 9 are connected by two sets of telescopic beams. The adjustable lifting legs 9 adopt the conventional H-type lifting legs used in small adjustable belt conveyors 4. The two sets of H-type lifting legs, together with the two sets of telescopic beams, can ensure that the entire belt conveyor frame stands firmly on the ground. In addition, to facilitate the movement of the belt conveyor, a universal wheel with brakes is installed at the bottom of each set of adjustable lifting legs 9.

[0029] To achieve the length extension design of the belt conveyor, its left frame 1 includes two parallel left beams 101, and an extension beam 102 is installed at the end of each of the two left beams 101 near the right frame 2. A follower roller 106 is rotatably installed on the opposite side of the front end of the two extension beams 102. A left belt support plate 103 is horizontally fixed between the two left beams 101. Several left connecting plates 104 are integrally formed at equal intervals from left to right at the end of the left belt support plate 103 near the right frame 2. When the auxiliary frame 3 is angled, in order to make the transition of the conveyor belt 4 between the inclined conveying section and the platform conveying section smoother and reduce the friction of the conveyor belt 4, a transition roller 105 is rotatably installed at the end of the two left beams 101 away from the right frame 2.

[0030] The right frame 2 includes two hollow right beams 201 that are opposite to the left beam 101 in the left frame 1. Two extension beams 102 are slidably inserted into the right beams 201 on the corresponding side. A clearance groove is provided on the opposite side of the two right beams 201 in the right frame 2 along the sliding direction of the extension beams 102 so that the follower rollers 106 can move with the movement of the extension beams 102. In order to make the displacement between the left frame 1 and the right frame 2 smoother, several rollers are hinged at equal distances at the top and bottom of the extension beams 102. The rollers are preferably silent rubber wheels.

[0031] To ensure better connection and coordination between the right frame 2 and the left frame 1, a right belt support plate 202 is horizontally fixed between the two right beams 201. Several right connecting plates 203 are integrally formed at the gaps between adjacent left connecting plates 104 on the left side of the right belt support plate 202 near the left frame 1. The right belt support plate 202 and the left belt support plate 103, as well as the right connecting plates 203 and the left connecting plates 104, are all on the same plane. The several left connecting plates 104 and the right connecting plates 203 are connected by an interlocking mechanism. The alternating sliding plug-in connection allows the gap between the left connecting plate 104 and the right connecting plate 203 to be filled and closed after the left frame 1 and the right frame 2 are closed, forming a complete belt lifting panel. In order to improve the compressive strength of the left connecting plate 104 and the right connecting plate 203, cross beams are fixed at opposite ends of the two left beams 101 and the two right beams 201 to support the right connecting plate 203 and the left connecting plate 104 respectively. The bottom of the left connecting plate 104 and the right connecting plate 203 slides against the surface of the cross beam at the corresponding position.

[0032] A driven roller 204 is rotatably mounted between the ends of the two right beams 201 away from the left frame 1, while a secondary roller 205 is rotatably mounted at the bottom of the other ends of the two right beams 201 via a bracket. The height of the secondary roller 205 is lower than that of the driven roller 106.

[0033] The platform conveying unit includes a sub-frame 3 hinged to the left frame 1. The sub-frame 3 includes two sub-beams 301 rotatably mounted at the ends of the two left beams 101 via an arbitrary angle adjustment plate 7, and rollers 305 rotatably mounted at the bottom of the two arbitrary angle adjustment plates 7. A drive roller 304 is also rotatably mounted at the end of the two sub-beams 301 away from the left beam 101. One end of the drive roller 304 is connected to a drive motor assembly 303 mounted at the bottom of one of the sub-beams 301. A sub-belt support plate 302 is installed between the two sub-beams 301. The drive motor assembly 303 includes a drive motor and gears mounted on the output shaft of the drive motor and at the end of the drive roller 304. The two gears are connected by a chain drive.

[0034] To facilitate the telescopic adjustment between the left frame 1 and the right frame 2, the frame at the bottom supporting the conveyor also needs to be telescopic. Specifically, the telescopic beam mainly consists of a plug beam 10 and a sleeve beam 11. The plug beam 10 and the sleeve beam 11 are slidably plugged together, and the plug beam 10 and the sleeve beam 11 are respectively fixed to the bottom of two sets of adjustable lifting legs 9. The outer side of the tube end of the sleeve beam 11 is provided with a locking bolt. During the length adjustment process, the locking bolt needs to be loosened in advance so that the plug beam 10 and the sleeve beam 11 can slide freely. After the length adjustment between the left frame 1 and the right frame 2 is completed, the locking bolt can be tightened again.

[0035] In order to control the operation of the belt conveyor, a start controller 12 for controlling the drive motor assembly 303 is installed on the outside of one of the adjustable lifting legs 9.

[0036] To ensure stable belt conveying while maintaining its extendable and adjustable function, the conveyor belt 4 sequentially passes through the drive roller 304, transition roller 105, driven roller 204, auxiliary roller 205, follower roller 106, idler roller 305, and drive roller 304 to form a closed loop. During the extension and retraction adjustment between the left frame 1 and the right frame 2, the follower roller 106 moves left and right following the extension beam 102. The distance between the follower roller 106 and the auxiliary roller 205 is the extension and retraction distance of the entire conveyor. If the conveyor belt 4 is missing or extra during the extension or retraction adjustment, it will be automatically compensated by the movement of the follower roller 106, thereby ensuring the tension between the conveyor belt 4 and the drive roller 304 and driven roller 204.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
