Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyors, in particular to a large-angle adjustment mechanism for a belt conveyor. Background Art

[0002] Belt conveyor is a commonly used continuous conveying equipment, mainly composed of a frame, conveyor belt, belt roller, tensioning device, transmission device, etc. It drives the conveyor belt to move under the action of the roller through a power device to transport materials from one place to another. The conveyor belt is made of multiple layers of rubber, polyester fiber and other materials, and has a certain flexibility and load-bearing capacity. One end of the conveyor belt is fixed on the bracket, and the other end is gripped on the driving and tensioning device, so that when the driving device is started, the conveyor belt will drive the material forward. The support roller and the transmission roller play the role of supporting the conveyor belt and transmitting power. The belt conveyor has the advantages of large conveying capacity, simple structure, easy maintenance, and standardized components. It is widely used in mining, metallurgy, coal and other industries. When the belt conveyor is used in plain mines and other places, the belt conveyor is often equipped with an angle adjustment mechanism to facilitate the adjustment of its conveying angle, so as to improve the adaptability of the belt conveyor to the environment during use, but it still has the following disadvantages in actual use:

[0003] The utility model with publication number CN219636203U discloses a belt conveyor height and angle adjustment device, wherein a leg assembly is fixedly connected to a conveyor frame, the leg assembly comprises a fixed plate, an angle adjustment plate is connected to the outer side of the fixed plate by connecting bolts, an upper leg is connected below the angle adjustment plate, a lower leg is movably connected to the lower leg at the lower end of the upper leg, and the lower end of the lower leg is connected to a working platform, the angle adjustment device can adjust the conveying angle of the belt in the vertical direction, undertake and convey materials of different heights, and improve the convenience of use, but in a field environment, when conveying, it is often necessary not only to consider the height difference between the two places, but also to consider whether there are obstacles in the environment that hinder the belt conveyor from adjusting the angle, and the angle adjustment device has a limited angle adjustment range for the belt conveyor;

[0004] When the belt conveyor needs to be adjusted at a larger angle, the impact caused by the material falling onto the belt surface is often larger. The larger impact often causes damage to the support frame of the belt conveyor and reduces the service life of the belt conveyor. Utility Model Content

[0005] The purpose of the present utility model is to provide a large-angle adjustment mechanism for a belt conveyor. Through a moving base, a belt support frame, and an angle adjustment component, it solves the problem that the angle adjustment mechanism of the belt conveyor can only adjust the vertical angle of the belt, making it difficult to be applicable to the field environment with many obstacles. Moreover, when the adjustment mechanism makes a large-angle adjustment to the belt, the impact force generated by the material falling onto the belt surface is relatively large, which is likely to damage the belt conveyor.

[0006] To solve the above technical problems, the present utility model is realized through the following technical solutions:

[0007] The present utility model is a large-angle adjustment mechanism for a belt conveyor, including a moving base, a belt support frame, and an angle adjustment component. A filter screen is fixedly clamped inside the moving base. A first stepping motor is arranged on one side of the moving base. Multiple belt support frames are arranged on the top of the moving base from bottom to top. A shock-absorbing airbag is arranged on the top of each belt support frame. A second stepping motor is arranged on one side of each belt support frame. An angle adjustment component is slidably clamped on one side of the moving base and multiple belt support frames. A rotating support frame is clamped on the top of each angle adjustment component. A slider is welded and fixed on one side of each angle adjustment component. One end of the slider penetrates and is clamped with a threaded pipe. A conveyor belt is rotatably clamped inside each belt support frame;

[0008] When the material is conveyed to the moving base, the material first falls onto the filter screen for filtration and then moves to the required position for further processing of the material. After an angle adjustment of a belt support frame, the shock-absorbing airbag on the upper side of the adjacent bottom belt support frame is moved to an appropriate position, and the shock-absorbing airbag is inflated to expand and press against the bottom side of the angle-adjusted belt support frame, so that when the material falls onto the surface of the conveyor belt, the shock-absorbing airbag can buffer the conveyor belt and the belt support frame, reducing the damage probability of the belt support frame. By the first stepping motor and the second stepping motor, the positions between the moving base and the belt support frame, and between the belt support frames can be adjusted, so that the material conveyed by one conveyor belt can fall onto the surface of the adjacent conveyor belt when the belt conveyor is in use, and the belt conveyor can be folded in the vertical direction when not in use, which is convenient for storage and transportation. The rotating support frame can rotate horizontally on the angle adjustment component, and the belt support frame can rotate vertically on one side of the rotating support frame to greatly adjust the conveying angle of the material, so that the belt conveyor can be applicable to the environment with obstacles and improve the convenience of use.

[0009] Further, moving wheels are rotatably clamped on both sides of the bottom of the moving base, and a waste residue chute is opened on the top of the moving base. The filter screen is clamped inside the waste residue chute;

[0010] The moving wheel can drive the adjusting mechanism to move, thereby improving the convenience of transportation and use. The dust and waste residue filtered by the filter can be moved and discharged along the waste residue chute, and the material can be discharged from the other end of the mobile base along the filter, which is convenient for the collection and further use of the material.

[0011] Furthermore, a first positioning slot is provided on one side of the mobile base, a first threaded rod is rotatably connected to one end of the first stepper motor, the first threaded rod and the first stepper motor are connected to the inner side of the first positioning slot, a slider of the angle adjustment assembly is slidably connected to the first positioning slot, and the first threaded rod is threadedly connected to one end of the threaded tube;

[0012] The first stepper motor can drive the first threaded rod to rotate, so that an angle adjustment component drives a belt support frame to move along the first positioning slide groove, and the relative position between the mobile base and the belt support frame is adjusted, so that the material transported by a conveyor belt of the belt conveyor can fall onto the filter surface when the belt conveyor is needed, and the belt conveyor can be folded vertically when not in use, which is convenient for storage and transportation.

[0013] Furthermore, each of the belt support frames has driving rollers rotatably connected at both ends, and a driving motor is penetrated and clamped on one side of each of the belt support frames, and the driving motor is connected through the belt support frame and the driving roller, and the driving roller is attached to the inner side of the conveyor belt, and a movable slide groove is provided at the top of each of the belt support frames, and a limiting plate is welded and fixed at the bottom of each of the belt support frames, and a second positioning slide groove is provided on one side of each of the belt support frames, and a second threaded rod is rotatably connected to one end of the second stepper motor, and the second stepper motor and the second threaded rod are clamped on the inner side of the second positioning slide groove, and a slider of the angle adjustment assembly is slidably connected to the inner side of the second positioning slide groove, and the second threaded rod penetrates and is screwed on one end of the threaded tube;

[0014] The driving motor can drive the driving roller to rotate, and further drive the conveying belt to rotate to transport the material. The limit plate can limit the shock-absorbing airbag to prevent the expanded shock-absorbing airbag from squeezing the conveying belt and affecting the conveying efficiency. The second stepper motor can drive the second threaded rod to rotate, so that an angle adjustment component drives a belt support frame to move along the second positioning slide groove, and the relative position between two adjacent belt support frames is adjusted, so that the material conveyed by one conveying belt can fall to the surface of the adjacent conveying belt when the belt conveyor is needed, and the belt conveyor can be folded vertically when not in use, which is convenient for storage and transportation.

[0015] Furthermore, a slide plate is fixedly connected to the bottom of each shock-absorbing airbag, and the slide plate is slidably connected to the inner side of the movable slide groove, and an air pump is connected to the bottom of the slide plate, and the air pump is connected to the shock-absorbing airbag through the slide plate;

[0016] After the angle of a belt support frame is adjusted, the slide plate on the upper side of the adjacent bottom-side belt support frame slides along the moving chute to an appropriate position, and the shock-absorbing airbag is inflated by an air pump so that it expands and presses against the bottom of the limiting plate. When the material falls onto the surface of the corresponding conveyor belt, the shock-absorbing airbag can buffer the conveyor belt and the belt support frame, reducing the probability of damage to the belt support frame.

[0017] Further, a first rotating motor is clamped at the bottom of each of the rotating support frames, and a second rotating motor is clamped through one side of each of the rotating support frames. The bottom end of the first rotating motor is clamped to the top of the angle adjustment assembly, and one end of one of the second rotating motors is rotatably clamped to one side of a belt support frame;

[0018] When adjusting the angle of the belt support frame, the first rotating motor can drive the belt support frame to adjust the angle in the horizontal direction, and the second rotating motor can drive the belt support frame to adjust the angle in the vertical direction, greatly adjusting the conveying angle of the material, so that the belt conveyor can be applicable to an environment with obstacles, improving the convenience of use.

[0019] The utility model has the following beneficial effects:

[0020] By providing a belt support frame and an angle adjustment assembly, the utility model solves the problem that the angle adjustment device can adjust the conveying angle of the belt in the vertical direction, receive and convey materials at different heights, and improve the convenience of use. However, in the wild environment, when conveying, it is often necessary to consider not only the height difference between two places, but also whether there are obstacles in the environment that hinder the angle adjustment of the belt conveyor, and the angle adjustment range of the angle adjustment device for the belt conveyor is limited. When adjusting the angle of the belt support frame, the first rotating motor drives the belt support frame to adjust the angle in the horizontal direction, and the second rotating motor drives the belt support frame to adjust the angle in the vertical direction, greatly adjusting the conveying angle of the material, so that the position of the belt conveyor can avoid obstacles in the environment, improving the convenience of use.

[0021] The utility model solves the problem that when a large-angle adjustment mechanism of a belt conveyor needs to make a large-angle adjustment to the belt conveyor, the impact generated when the material falls onto the belt surface is often large, and the large impact often causes damage to the support frame of the belt conveyor and shortens the service life of the belt conveyor by setting a belt support frame. After an angle adjustment of a belt support frame, the sliding plate on the upper side of the adjacent bottom-side belt support frame is slid along the moving chute to an appropriate position, and the shock-absorbing airbag is inflated by an air pump so that it expands and presses against the bottom of the limiting plate. When the material falls onto the corresponding conveyor belt surface, the shock-absorbing airbag buffers the conveyor belt and the belt support frame, reducing the damage probability of the belt support frame.
