Description

Technical Field

[0001] This application belongs to the field of material conveying technology, specifically relating to an oscillating belt conveyor and conveying method. Background Technology

[0002] In industrial material conveying and distribution systems, especially in scenarios involving multiple silos arranged side-by-side, achieving efficient and precise material distribution remains a key aspect of engineering design. For situations with multiple silos side-by-side, existing technologies often employ oscillating belt conveyors as material transfer equipment. This equipment uses its entire conveyor to oscillate horizontally around a fulcrum at one end, utilizing the arc-shaped trajectory of the discharge port to sequentially connect to the inlets of each silo arranged in a straight line, thus achieving point-to-point material supply from a single unit to multiple silos. This arrangement offers advantages in simplifying equipment configuration, saving space, and reducing investment costs, and is therefore widely used in metallurgy, building materials, chemical, and grain storage and transportation fields.

[0003] However, in actual operation, the above-mentioned technical solution has obvious structural compatibility problems. Specifically, when the oscillating belt conveyor is working, the trajectory of its discharge end is an arc with the oscillation fulcrum as the center; while the feed inlets of multiple hoppers are usually arranged in parallel in a straight line according to factors such as plant layout, process pipelines, and space utilization. Due to the geometric mismatch between the straight arrangement of the hopper feed inlets and the arc-shaped trajectory of the oscillating belt conveyor, when the belt conveyor oscillates to different positions, it is difficult to achieve precise alignment between the center line of its discharge port and the center line of the corresponding hopper feed inlet. This alignment deviation varies at different oscillation angles: the deviation is relatively small at the hopper in the middle position, while as the oscillation angle increases, the alignment error at the far-end hoppers on both sides increases significantly, resulting in a misalignment gap between the discharge port and the feed inlet.

[0004] In this situation, as materials fall from the oscillating conveyor belt into the hopper, they are highly susceptible to scattering outside the hopper due to alignment deviations, causing material leakage. Material leakage not only results in direct loss of raw materials and increased production costs, but also accumulates around the equipment, affecting the cleanliness and safety of the production environment, increasing the burden of manual cleaning, and in severe cases, may even interfere with the normal oscillation of the conveyor belt, causing equipment jamming or malfunctions, and hindering the continuous and stable operation of the system. Therefore, how to effectively solve the alignment deviation problem between the oscillating conveyor belt's arc-shaped motion trajectory and the linearly arranged hoppers while maintaining the flexibility of the conveyor belt layout, and thus prevent material leakage, has become a pressing technical challenge in this field. This problem is exacerbated, especially in port or open-air applications, when crosswinds are encountered. Summary of the Invention

[0005] This application aims to at least solve one of the aforementioned technical problems existing in the prior art. To this end, in a first aspect, this application provides a swing belt conveyor capable of solving the deviation problem when connecting different hoppers and the deviation problem that may occur during the material feeding process.

[0006] Secondly, this application provides a conveying method applied to the above-mentioned oscillating belt conveyor.

[0007] The oscillating belt conveyor according to the first aspect of this application includes: Rotary support mechanism; An arc-shaped guide rail is provided on the side closest to the hopper; The belt conveyor has its feed end rotatably mounted on the rotary support mechanism. A traveling support mechanism is provided on the side of the belt conveyor near the hopper. The traveling support mechanism is rolled on the arc-shaped guide rail and is used to control the discharge end of the belt conveyor to swing around the feed end. A first locking mechanism is disposed between the walking support mechanism and the arc-shaped guide rail, for limiting the movement of the walking support mechanism relative to the arc-shaped guide rail; A second locking mechanism is provided between the belt conveyor and the hopper to restrict the movement of the belt conveyor relative to the hopper; The detection mechanism is used to detect whether the belt conveyor has reached the position for docking with the hopper; The control system connects the walking support mechanism, the first locking mechanism, the second locking mechanism, and the detection mechanism. It is used to control the belt conveyor to swing, and when the detection mechanism detects that the belt conveyor has reached the position to dock with the hopper, it first controls the corresponding first locking mechanism to lock, and then controls the second locking mechanism to lock.

[0008] The oscillating belt conveyor according to the embodiments of this application has at least the following beneficial effects: The oscillating belt conveyor provided in this application, through the cooperation of a rotating support mechanism and an arc-shaped guide rail, enables the conveyor to oscillate along a preset arc-shaped trajectory, thereby adapting to the geometric relationship between the linear arrangement of multiple hoppers and the arc-shaped movement trajectory of the discharge end. Based on this, by setting up a first locking mechanism and a second locking mechanism, combined with the linkage control of the detection mechanism and the control system, double locking is achieved after oscillation positioning: first, the first locking mechanism locks the traveling support mechanism to the arc-shaped guide rail, and then the second locking mechanism locks the conveyor and the hopper relative to each other. This step-by-step locking method not only ensures the overall positional stability of the conveyor but also further eliminates residual offset between the discharge end and the hopper inlet, effectively preventing material leakage due to positioning deviation. It is understandable that, since the oscillating belt conveyor is set at an angle, that is, its feeding end is located at a low position and its unloading end is set at a high position, in order to transfer materials into the silo, this application uses the first locking mechanism and the second locking mechanism to limit and fix the unloading end of the belt conveyor from the low position and the high position respectively. This can effectively improve the overall stability of the belt conveyor during the unloading process. While maintaining the flexibility of the oscillating belt conveyor layout, it effectively solves the problem of centering deviation between its arc-shaped motion trajectory and the straight-lined silo, prevents material leakage, and can effectively cope with crosswinds.

[0009] According to some embodiments of this application, the first locking mechanism includes: A clamping assembly is detachably disposed on both sides of the arc-shaped guide rail. The clamping assembly is provided with a clamping head, which has a tapered structure protruding along one side close to the arc-shaped guide rail. A clamping seat is disposed on the walking support mechanism, and tapered recesses are provided on opposite sides of the clamping seat; As the clamping head gradually embeds into the conical recess, it can push the walking support mechanism to move along the arc-shaped guide rail, so that the clamping head and the clamping seat are automatically aligned.

[0010] According to some embodiments of this application, the clamping assembly is provided with a clamping drive, which is connected to the two clamping heads to drive the clamping heads to move towards each other.

[0011] According to some embodiments of this application, the second locking mechanism includes: A locking part is fixedly installed on the side of the belt conveyor near the hopper; A locking assembly is provided on each of the hoppers along the swing path of the locking part. The locking assembly includes a damping part and a limiting part. The damping part is symmetrically arranged on the upper and lower sides of the swing path, and the limiting part is movable to enter or exit the swing path. When the locking part moves to the position of the locking assembly along with the belt conveyor, it first abuts against the damping part to reduce the moving speed, and then abuts against the limiting part to restrict the movement.

[0012] According to some embodiments of this application, the locking part is configured as a rod structure protruding toward the hopper.

[0013] According to some embodiments of this application, the locking assembly is provided with two limiting portions. Along the swing path, the two limiting portions are located on both sides of the locking portion at a set position where it is docked with the hopper, so as to limit the locking portion at the set position where it is docked with the hopper.

[0014] According to some embodiments of this application, along the swing direction of the locking part, inclined surfaces or arc surfaces are provided on both sides of the damping part, the two damping parts that are opposite each other can be opened and closed for adjustment, and the two limiting parts correspond to one damping part respectively; The locking part can push the damping parts away from each other, and when the locking part reaches the set position of docking with the hopper, the two limiting parts press against one of the damping parts respectively, so as to control the two damping parts to press against the locking part.

[0015] According to some embodiments of this application, the detection mechanism includes an angle detection unit disposed on the rotating support mechanism.

[0016] According to some embodiments of this application, the unloading end of the belt conveyor is rotatably equipped with a baffle, the control system is connected to the baffle, and when the belt conveyor is connected to different hoppers, the control system controls the baffle to rotate to the corresponding angle.

[0017] The conveying method according to the second aspect of this application, applied to the above-mentioned oscillating belt conveyor, includes: Step S1: The control system receives the target silo instruction; Step S2: Drive the belt conveyor to rotate around the rotary support mechanism at its feed end, while the traveling support mechanism moves along the arc-shaped guide rail and swings. Step S3: When the detection mechanism detects that the belt conveyor is approaching the target hopper, it triggers deceleration; Step S4: Control the first locking mechanism to lock the traveling support mechanism, and then control the second locking mechanism to lock the belt conveyor; Step S5: Start the belt conveyor to feed materials.

[0018] The conveying method according to the embodiments of this application has at least the following beneficial effects: The conveying method provided by this application forms a complete automated control process by sequentially executing steps such as swinging, deceleration, first locking, second locking, and feeding. This method first completes the coarse positioning and locking of the overall position, and then completes the fine positioning and locking of the local position, effectively avoiding the problem of accumulated positioning errors that may exist in a single locking mechanism, and realizing efficient, accurate, and reliable switching of the swing belt conveyor between multiple hoppers.

[0019] Additional aspects and advantages of this application will be set forth in part in the description which follows, and some of these additional aspects and advantages will become apparent from the description or may be learned by practice of this application. Attached Figure Description

[0026] Reference Figures 1 to 8 This embodiment provides a swing belt conveyor, mainly used to enable a single belt conveyor 100 to selectively feed multiple hoppers 400 arranged in a straight line. The swing belt conveyor includes a rotating support mechanism 200, an arc-shaped guide rail 300, a belt conveyor 100, a first locking mechanism, a second locking mechanism, a detection mechanism, and a control system.

[0027] A rotary support mechanism 200 is located at the feed end of the belt conveyor 100, serving as the rotation center for the belt conveyor 100's oscillation. The rotary support mechanism 200 can adopt a structure combining a slewing bearing and a rotary drive device. The outer ring of the slewing bearing is fixed to the mounting base, and the inner ring is fixedly connected to the feed end frame of the belt conveyor 100. The rotary drive device drives the belt conveyor 100 to rotate around the central axis of the slewing bearing via gear transmission, direct drive, or belt transmission. An angle detection unit is also installed at the rotary support mechanism 200 to detect the oscillation angle of the belt conveyor 100 in real time.

[0028] An arc-shaped guide rail 300 is positioned near the hopper 400, arranged in an arc-shaped manner with the rotation center of the rotary support mechanism 200 as the center and the length from the feed end to the discharge end of the belt conveyor 100 as the radius. The midpoint of the arc-shaped guide rail 300 coincides with the midpoints of multiple hoppers 400. The cross-sectional shape of the arc-shaped guide rail 300 can be V-shaped, rectangular, or I-shaped to provide a stable rolling support surface. A traveling support mechanism 101 is provided on the side of the belt conveyor 100 near the hopper 400, and a set of traveling wheels 1011 is mounted at the lower end of the traveling support mechanism 101 to roll in cooperation with the arc-shaped guide rail 300. When the belt conveyor 100 oscillates around the rotary support mechanism 200, the traveling support mechanism 101 rolls along the arc-shaped guide rail 300, thereby providing support and guidance for the discharge end of the belt conveyor 100.

[0029] The first locking mechanism is located between the traveling support mechanism 101 and the arc-shaped guide rail 300. It is used to lock the traveling support mechanism 101 onto the arc-shaped guide rail 300 when the belt conveyor 100 swings to the target hopper 400 position, so as to prevent the belt conveyor 100 from swinging unexpectedly during subsequent operations.

[0030] The second locking mechanism is located between the belt conveyor 100 and the hopper 400. It is used to lock the belt conveyor 100 and the target hopper 400 relative to each other after the belt conveyor 100 swings into position, thereby further eliminating the positional deviation between the unloading end and the feed inlet of the hopper 400.

[0031] The testing agency is used to check whether the belt conveyor 100 has reached the docking hopper 400.

[0032] The control system is electrically connected to the drive unit, first locking mechanism, second locking mechanism, and detection mechanism of the walking support mechanism 101, and is used to coordinate and control the timing of the actions of each component. Specifically, the control system can be a programmable logic controller or an industrial control computer.

[0033] Understandably, each 400mm hopper corresponds to a specific angle for unloading, for example, referring to... Figure 2 and Figure 3 Using the line connecting the midpoint of the arc-shaped guide rail 300 and the center of the rotating support mechanism 200 as the 0° coordinate line, four hoppers 400 are vertically arranged. When the belt conveyor 100 is aligned upwards with the first hopper 400, the angle is... When connecting to the second 400 hopper, the angle of the belt conveyor is 100°. When connecting downwards to the first 400mm hopper, the angle of the belt conveyor is 100°. When connecting to the second 400 hopper, the angle of the belt conveyor is 100°. Therefore, during operation, the control system acquires the material hopper 400 that needs to be fed, and then, based on the set angle at which the belt conveyor 100 connects to the material hopper 400, controls the belt conveyor 100 to swing to the set angle. A detection mechanism is then used to determine whether the belt conveyor 100 is properly connected to the corresponding material hopper 400. After reaching the set angle, the control system first controls the first locking mechanism to lock, preventing the traveling support mechanism 101 from continuing to move along the arc-shaped guide rail 300. Then, it controls the second locking mechanism to lock, establishing a locked connection between the belt conveyor 100 and the material hopper 400.

[0034] It is also understood that the oscillation of the belt conveyor 100 can be driven separately in the rotary support mechanism 200, driven separately in the traveling support mechanism 101, or driven simultaneously in both the rotary support mechanism 200 and the traveling support mechanism 101. Those skilled in the art can flexibly set it as needed.

[0035] In this embodiment, the oscillating belt conveyor 100, through the cooperation of a rotating support mechanism 200 and an arc-shaped guide rail 300, allows the conveyor 100 to oscillate along a preset arc-shaped trajectory, thereby adapting to the geometric relationship between the linear arrangement of the multiple hoppers 400 and the arc-shaped movement trajectory of the discharge end. Furthermore, by setting up a first locking mechanism and a second locking mechanism, combined with the linkage control of the detection mechanism and the control system, double locking is achieved after oscillation positioning: first, the first locking mechanism locks the traveling support mechanism 101 to the arc-shaped guide rail 300, and then the second locking mechanism locks the conveyor 100 relative to the hoppers 400. This step-by-step locking method ensures the overall positional stability of the conveyor 100 and further eliminates residual offset between the discharge end and the feed inlet of the hopper 400, effectively preventing material leakage due to positioning deviation. It is understandable that, since the oscillating belt conveyor is set at an angle, that is, its feeding end is located at a low position and its unloading end is set at a high position, in order to transfer the material into the silo 400, this application uses the first locking mechanism and the second locking mechanism to limit and fix the unloading end of the belt conveyor 100 from the low position and the high position respectively. This can effectively improve the overall stability of the belt conveyor 100 during the unloading process. While maintaining the flexibility of the oscillating belt conveyor layout, it effectively solves the problem of the centering deviation between its arc-shaped motion trajectory and the straight-lined silo 400, prevents material leakage, and can effectively cope with crosswinds.

[0036] Combination Figure 6 and Figure 7In some embodiments, the first locking mechanism adopts a clamp-type automatic centering structure. Specifically, the first locking mechanism includes a clamp assembly 102 and a clamping seat 103. The clamp assembly 102 is disposed on both sides of the arc-shaped guide rail 300, and its two clamping heads 1021 are respectively located on opposite sides of the arc-shaped guide rail 300. The two clamping heads 1021 are connected by a clamp drive transmission and can move towards each other or away from each other under the command of the control system. The side of the clamping head 1021 facing the arc-shaped guide rail 300 is configured with a protruding conical structure. The clamping seat 103 is fixedly disposed on the walking support mechanism 101, and conical recesses 1031 matching the conical structure of the clamping head 1021 are respectively provided on opposite sides of the clamping seat 103. When the clamping drive drives the two clamping heads 1021 to move towards each other, the clamping heads 1021 gradually embed into the conical recess 1031 of the clamping seat 103. During this process, the radial component force generated by the conical surface contact can push the walking support mechanism 101 to make a small displacement along the arc-shaped guide rail 300 until the clamping head 1021 and the clamping seat 103 are completely in contact, thereby realizing the automatic centering and locking between the walking support mechanism 101 and the arc-shaped guide rail 300.

[0037] Since the clamping assembly 102 is fixed with reference to the set angle during installation, when there is a slight deviation between the swing angle of the walking support mechanism 101 when it stops and the set angle, the clamping assembly 102 can be used to correct it, thereby ensuring the accuracy of the swing angle.

[0038] Combination Figure 6 Specifically, in some embodiments, the clamping drive adopts a motor-screw transmission structure, and a guide structure, such as a guide post or guide rail, is provided between the two clamping heads 1021. During operation, the control system controls the motor to rotate, thereby moving the clamping heads 1021 closer together or further apart.

[0039] In some embodiments, the two clamping heads 1021 are rotatably mounted. During rotation, the upper ends of the two clamping heads 1021 can be adjusted to open and close, and this adjustment is accompanied by a lifting adjustment. Specifically, the clamping assembly 102 has pits on both sides of the arc-shaped guide rail 300. The bottoms of the two clamping heads 1021 are rotatably mounted within these pits, and their upper ends can extend upwards during rotation to clamp the clamping seat 103. A telescopic adjustment structure, such as a hydraulic cylinder or linear motor, is provided for each of the two clamping heads 1021 to drive the clamping heads 1021 to rotate. Using the structure of this embodiment, the clamping heads 1021 can be concealed within the pits when open, achieving a hidden design.

[0040] Combination Figure 8In some embodiments, the second locking mechanism includes a locking part 104 and a locking assembly. The locking part 104 is fixedly disposed on the side of the belt conveyor 100 near the hopper 400, and may specifically adopt a rod structure protruding towards the hopper 400, with a smooth outer surface to reduce frictional resistance when in contact with the damping part 105. The locking assembly is disposed on each hopper 400 along the swing path of the locking part 104, that is, each hopper 400 is provided with a corresponding set of locking assemblies. The locking assembly includes a damping part 105 and a limiting part 106. The damping parts 105 are symmetrically disposed on the upper and lower sides of the swing path, and the two damping parts 105 are disposed opposite each other, with the two sides of their opposite surfaces being set as inclined or arc surfaces to form a guide when the locking part 104 enters. The two damping parts 105 adopt an adjustable structure, that is, the distance between them can vary within a certain range. The limiting part 106 can move up and down. When locking is required, the limiting part 106 rises / falls into the swing path; when unlocking is required, the limiting part 106 falls / rises out of the swing path.

[0041] During the oscillation of the belt conveyor 100, the locking part 104 moves with the belt conveyor 100. When it approaches the target hopper 400, the locking part 104 first enters between the upper and lower damping parts 105. The damping parts 105 apply damping force to the locking part 104, causing its moving speed to gradually decrease. When the locking part 104 continues to move to the set position, the locking part 104 abuts against the limiting part 106, which restricts its continued movement. At this time, the locking part 104 is exactly located at the precise position of docking with the hopper 400. To further improve the locking stability, this embodiment provides two limiting parts 106 in each locking assembly, located on both sides of the locking part 104 when it is in the docking set position, forming a bidirectional limiting.

[0042] Combination Figure 8 In some embodiments, the two limiting parts 106 correspond to one damping part 105. When the locking part 104 reaches the set position, the two limiting parts 106 press the corresponding damping parts 105 respectively. That is, one limiting part 106 is installed above the swing path and one limiting part 106 is installed below the swing path. During lifting and lowering, the two damping parts 105 press the locking part 104 from the upper and lower sides, thereby forming a continuous and stable holding force.

[0043] Specifically, the locking assembly has two mounting seats, which are symmetrically fixed to the hopper 400. Two damping parts 105 are each mounted on one mounting seat and are vertically slidably installed. A spring 1052 is provided on the opposite side of the two damping parts 105 on each mounting seat. The spring 1052 holds the damping parts 105 together, ensuring they remain close together when no external force is applied and move away from each other when an external force is applied. Along the swing direction of the locking part 104, the damping part 105 has inclined surfaces on both sides and a plane connecting the two inclined surfaces. A limiting part 106 extends from the area corresponding to this plane and enters the swing path of the locking part 104. A nylon layer 1051 is provided on the side of the damping part 105 facing the swing path to balance lifespan and damping effect.

[0044] In some embodiments, the detection mechanism includes an angle detection unit disposed at the rotary support mechanism 200. The angle detection unit may be an absolute encoder or a rotary transformer, capable of outputting the swing angle value of the belt conveyor 100 in real time. The control system determines whether the belt conveyor 100 is close to or has reached the target hopper 400 position based on the angle value fed back by the angle detection unit and in conjunction with the pre-stored angle threshold values ​​corresponding to each hopper 400.

[0045] In some embodiments, the detection mechanism includes a proximity switch or radio sensor corresponding to the walking support mechanism 101, which triggers the detection mechanism when the walking support mechanism 101 moves to a set position on the arc-shaped guide rail 300.

[0046] Based on the structural foundation provided by the above embodiments, in some embodiments, this application also proposes a conveying method using a swing belt conveyor. This method specifically includes the following steps: In step S1, the control system receives a target silo 400 instruction sent by the host computer or operation panel. This instruction contains the number information of the target silo 400.

[0047] In step S2, the control system retrieves the pre-stored target angle value corresponding to the target hopper 400 based on its number, and obtains the locking assembly located on the path of the belt conveyor 100 rotating to dock with the target hopper 400. First, it controls the locking assembly on the path to raise and lower the limiting part 106 completely out of the swing path of the locking part 104. Then, it controls the locking assembly on the target hopper 400 to move the limiting part 106, which is used to stop the locking part 104, onto the swing path. Next, it controls the rotary support mechanism 200 to start, or controls the traveling support mechanism 101 to start, driving the belt conveyor 100 to rotate around its feed end, causing the belt conveyor 100 to swing towards the target hopper 400. During the swing, the angle detection unit provides real-time feedback of the current angle value. The control system compares the current angle value with the target angle value. When the difference between the two is less than a preset deceleration threshold, it proceeds to the next step.

[0048] In step S3, the control system controls the belt conveyor 100 to decelerate, so that the belt conveyor 100 approaches the target hopper 400 at a low speed.

[0049] In step S4, when the difference between the angle value fed back by the angle detection unit and the target angle value enters the allowable error range, the oscillation operation of the belt conveyor 100 is stopped, putting it into a powerless state. The control system first controls the first locking mechanism to move, driving the two clamping heads 1021 of the clamping assembly 102 to move towards each other. The clamping heads 1021 gradually embed into the conical recess 1031 of the clamping seat 103. During this process, the centering adjustment between the walking support mechanism 101 and the arc-shaped guide rail 300 is automatically completed until it is fully locked. Subsequently, the control system controls the second locking mechanism to move, driving the second limiting part 106 in the locking assembly at the target hopper 400 to rise / fall into the oscillation path, completing the front and rear limiting. Then, the two limiting parts 106 are simultaneously driven to continue moving along the direction of intrusion into the oscillation path, so that the damping part 105 presses the upper and lower sides of the locking part 104 to clamp the locking part 104, completing the relative locking between the belt conveyor 100 and the hopper 400.

[0050] In step S5, after the control system confirms that both the first locking mechanism and the second locking mechanism are in the locked state, it starts the conveyor motor of the belt conveyor 100 to start feeding material to the hopper 400.

[0051] Throughout the feeding process, the control system continuously monitors the feedback value of the angle detection unit. If the belt conveyor 100 is detected to deviate due to vibration or other external forces, the rotary drive device can be controlled to make minor adjustments to compensate for the deviation, ensuring the stability of the feeding process.

[0052] After the material feeding is completed, the control system first controls the belt conveyor 100 to stop running, and then controls the second locking mechanism to unlock and the first locking mechanism to unlock in sequence, so that the belt conveyor 100 returns to a state where it can swing freely, waiting for the next swing command.

[0053] It should be noted that the limiting part 106 in this method is controlled by a two-stage stroke. The first stage of the stroke is from the position of exiting the swing path of the locking part 104 to the position of entering the swing path. At this position, the limiting part 106 does not press the damping part 105, which has a lifting and lowering adjustment stroke. The second stage of the stroke continues to enter the swing path from the end of the first stage to press the damping part 105, forcing the damping part 105 to press the locking part 104.

[0054] In addition, a rotatable baffle 500 can be installed at the unloading end of the belt conveyor 100. A drive motor is installed between the baffle 500 and the frame of the belt conveyor 100. The control system controls the baffle 500 to rotate to the corresponding angle according to the current position of the docked hopper 400, so that the discharge direction of the baffle 500 is optimally matched with the feed inlet of the hopper 400, further preventing material leakage.

[0055] Combination Figure 3 Specifically, when the belt conveyor 100 connects to the hopper 400 at the middle position, the horizontal intrusion into the hopper 400 is greater. However, when connecting to the hopper 400 at the side position, the horizontal intrusion is less. Based on the position of the target hopper 400, the control system controls the baffle 500 to gradually rotate upwards in the direction from the middle to both sides (the arrangement direction of the hoppers 400), thereby limiting the material throwing distance. When connecting to the hopper 400 at the middle position, the baffle 500 rotates downwards at a certain angle to prevent material from being thrown too far beyond the hopper 400. When connecting to the hopper 400 at the side position, the baffle 500 rotates upwards at a certain angle to allow material to be smoothly fed into the hopper 400 from the middle position.

[0056] In summary, the oscillating belt conveyor and its conveying method provided in this application achieve stable oscillation of the belt conveyor 100 through the cooperation of the rotating support mechanism 200 and the arc-shaped guide rail 300. The sequential action of the two-stage locking mechanism achieves precise positioning and locking from the whole to the part. The automatic centering conical surface structure and the damping limit structure achieve position correction and buffer protection during the locking process. It effectively solves the problems of centering deviation and material leakage when the oscillating belt conveyor is docked with the linearly arranged silos 400. It has the advantages of high positioning accuracy, stable operation and high degree of automation.
